6   ## Summary
7   
8   Started as a plan to fix the SNKRX template's 60-edition shimmer/dither system, pivoted into building a brand-new **`ricochet-template`** (Anchor 2) implementing a clean, orthogonal **pattern × color × dither** effect system in the Ricochet dark-mode visual style, then spent most of the session exploring procedural background patterns and adding per-pattern modifiers via a gallery + inspector UI. Also diagnosed and fixed a 144Hz UI flicker rooted in the engine's update/render decoupling.
9   
10  **Origin & pivot (SNKRX editions → ricochet-template):**
11  - SNKRX's edition system had ~60 baked combos ("ruby", "lime") entangling color + animation + dither. Goal: make pattern, color, dither three orthogonal axes ("noise type X" + "color ruby" + "4x4 4-level dither").
12  - After examining `snkrx-template/snkrx/edition.lua` (548 lines) and its `assets/draw_shader.frag` (770 lines), the user decided to start a fresh project instead, using the **Ricochet** project's visual style (`Ricochet/design.md`) — specifically its **dark mode** ("blueprint room with the lights off": near-black field, warm off-white ink, few accents). New folder named `ricochet-template`.
13  
14  **Scaffolding & three-axis effect system:**
15  - Created `E:/a327ex/ricochet-template/`; copied `anchor/` + `anchor.exe` from snkrx-template (newest Anchor 2 build), `run.bat` (engine arg `ricochet-template`).
16  - `palette.lua`: two parallel 13-token tables (`palette_dark` default, `palette_light`), keys `field/panel/recess/ink/mid_light/mid_grey/deep_grey` + accents `blue/orange/green/pink/yellow/red`. `palette_init(mode)` selects active `palette`, pushes to shader.
17  - `effect.lua`: `effect_set(layer, spec)` writes shader uniforms; spec = `{pattern, color, dither, color_a, color_b, pattern_scale, speed, contrast, pattern_param}`. Registries `pattern_kinds`/`color_kinds`/`dither_kinds` + cycle helpers.
18  - `assets/draw_shader.frag`: replaces engine default. Pipeline `pattern_field()` → `apply_dither()` → `apply_color()`. `u_palette[13]` vec4 uniform array (written via `shader_set_vec4_immediate`). Color recipes: `none` (passthrough vColor), `solid` (palette[a]), `mix` (mix(a,b,f)).
19  - Font: dropped LanaPixel (pixel font wrong under smooth filter); used **CascadiaCode** (mono) for HUD, later added **Oswald-Medium** + **IBMPlexSans** for UI (copied from `Anchor2/site/assets/`).
20  
21  **Dither port (34 modes):**
22  - Ported the full snkrx dither catalog into shader + `effect.lua` (`dither_kinds`/`dither_cycle_names`/`dither_pretty_names`): 2-level group (bayer4_2/8_2/noise_2), multi-level Bayer (2_4,4_4,4_8,8_7,8_9,8_16), white-noise (4/8), cluster-dot (4/6/8), line_diag + line_diag_flip (2..8), scanlines (horiz/vert), triangle (5/6/7), hearts_6. Unified `dither_quantize(field, levels, threshold)` = `floor(f*L+t)/(L-1)`.
23  - Decision: support both 2-level (hard A/B) and multi-level (N-step `mix` interpolation); level count baked into each name.
24  
25  **UI toolkit (Ricochet aesthetic) + line-rendering lessons:**
26  - `rectcut.lua` (verbatim RectCut from snkrx ui/rect.lua), `ui_state.lua` (slimmed: hot/active/focus + `ui_claim_hot`, dropped text-input/modal), `ui.lua` (widgets: `ui_panel`, `ui_field`, `ui_segment`, `ui_swatch_row`, `ui_slider`, internal `ui_icon_button`).
27  - Dropped from snkrx: juice/springs, hover sounds, edition-paint wrappers, drop shadow, rounded corners — per design.md "no bounce easings, no shadows."
28  - **Line-rendering investigation:** `layer_rectangle_line` (SDF stroke) at 1px in smooth-filter mode gives a soft 2-row ~50%-alpha band (Freya Holmér's Shapes "Line Thinness Fading" problem); 4× `layer_line` capsules overlap-blend at corners (visible darker squares). **Fix: hairlines as 1px filled `layer_rectangle`s** (one ~84%-alpha center row + faint halo) — crisp, no corner overlap. Added `hairline_rect`/`hline`/`vline`. Rule: hairline 1px → filled rect; heavy 3px+ → `layer_rectangle_line`; avoid 1-2px SDF strokes.
29  - **Design from the reference images, not design.md:** examined `Ricochet/reference/01-06`. They show ONE uniform pen weight with state via FILL/COLOR, not the doc's 1px/1.5px/3px tier claim. Switched active/selected to **inverted fill** (ink rect + field label) for `ui_segment`, persistent 1px ink frame for selected swatch. UI collapsed to one stroke weight.

4   # Visual Experiments 2
5   
6   ## Summary
7   
8   Continuation of the `ricochet-template` visual-experiments work (follows "Visual Experiments 1"). Extended the pattern × color × dither effect system with **local gradient patterns**, a **second per-pattern knob**, a **SHAPE axis** (field rendered as a grid of shapes), a **`ramp` color recipe** + an in-app **ramp editor**, then pivoted to **icon research** — built an Iconify→PNG pipeline, compared Phosphor/Tabler/Remix in a flat themed UI screen, chose **Tabler**, and rebuilt that screen as a full-width Tabler **UI kit**. Also fixed and documented a recurring **sprite-centering** engine gotcha and a latent `layer_line` framework-copy bug.
9   
10  **Local gradient patterns (linear + radial):**
11  - Added two patterns sampled from the draw's own `vUV` (rect-local) instead of `vPos` (world/global): `linear_gradient` (kind 10) and `radial_gradient` (kind 11). The field is locked to the rectangle's own box, so it moves/scales with the rect.
12  - Aspect-corrected via the quad's pixel size: hoisted a `vec2 quad_px` in the shader `main()`, set per shape branch (rect = `vShape0.xy`, circle = `vec2(vShape0.x)`, sprite = `vec2(texSize)`, etc.). Widened `effect_field(world_pos)` → `effect_field(world_pos, uv, quad_px)`; both call sites updated.
13  - `linear_gradient`: `param` = ANGLE (0..1 → 0..2π), aspect-corrected; ramp normalized corner-to-corner along the direction. `radial_gradient`: `param` = SHAPE, blends a true circle (inscribed, short side) ↔ rect-fitting ellipse.
14  - Via AskUserQuestion, the "how fast the gradient goes" control was decided to mean **transition steepness**, which is mechanically the existing universal **CONTRAST** modifier — so no new uniform; SCALE + SPEED are inert for gradients.
15  
16  **Second per-pattern knob (`param2`):**
17  - Added a general second intrinsic knob (`u_pattern_param2`) mirroring `param`, with a *per-pattern* slider range (`param2_min`/`param2_max`). Linear → **OFFSET** ([-1,1], slides the f=0.5 midline along the angle); radial → **RANGE** (0.25..3, scales the circle's reach). Conditional 5th MODIFIERS slider shown only when `param2_label` is set; sidebar height bumped.
18  
19  **SHAPE axis (4th axis) — field as a grid of shapes:**
20  - New `shape` axis (`shape_kinds`, `u_shape_kind`, `u_shape_size`), `apply_shape` between `effect_field` and dither. Cells anchored to screen space (`gl_FragCoord`), the same space as the dither. Shared SHAPE + CELL SIZE controls (like color/dither).
21  - First pass had three circle variants (size/fill/hard). User: "Let's try all these options" → made them selectable shape kinds.
22  - **Warping bug:** circles warped into blobs/crescents because the field was sampled per-fragment (f varies across a cell). Fixed by sampling the field **once per cell at the cell center**, reconstructing world_pos/uv there from screen-space derivatives (`dFdx`/`dFdy`) — exact for the 2D affine camera. Introduced `effect_field_shaped`.
23  - **Mask × fill decouple:** user wanted each circle to carry the effect's internal variation, not a flat tone. Generalized to two roles: **coverage** (mask, from the per-cell `fc` → true circle boundary) and **color/fill** (per-fragment `ff`). `shape_mask()` isolated as the single extension point for future image-stencil shapes.
24  - Removed `circle (fill)` per user ("too close to the raw effect"); kept `circle` (size) + `circle_hard`.
25  
26  **SNKRX editions — conceptual placement (no code):**
27  - Discussed where SNKRX's `dynamic` / `polychrome` / `palette_cycle` / `silver` editions fit. Conclusion: they're **COLOR recipes**. SNKRX fused (shimmer field + color transform + animation) into one "edition"; our pipeline already split those. So an edition decomposes: shimmer → pattern, animation → pattern `speed`, dither → dither, the color transform → the color axis.
28  - Key payoff: animated color is **free** — feed an animated pattern into a hue/ramp recipe and it sweeps over time without the recipe knowing about time; spatial color comes from gradient patterns. Only field-independent uniform time-cycling would need a new color-stage input (better expressed as a pattern). Ricochet caveat: a continuous rainbow fights the limited palette → use a **palette-token ramp** (quantized "polychrome").

5   
6   ## Summary
7   
8   Continuation of the `ricochet-template` visual-experiments work (follows "Visual Experiments 2"). This session closed out the remaining **icons/images** roadmap items (image-as-SHAPE + image-as-CONTENT), added the rest of the **geometric shapes** plus **shape rotation**, and did a major **API-simplification** pass that culminated in a unified **effect editor**. Also patched the shared **Anchor 2 engine** to bind auxiliary sampler textures for the regular draw path. The 480×270 work and replacing the snkrx-template effect stack were explicitly **deferred** to later manual sessions.
9   
10  **Alignment + scope decisions (up front):**
11  - Read Visual Experiments 2's summary + `ricochet-template/.claude/CLAUDE.md`. Surfaced a key finding: the roadmap's "image-as-SHAPE hook is READY via `layer_shader_set_texture`/`COMMAND_SET_UNIFORM_TEXTURE`" was **wrong** — for the draw shader that command only stashed the texture for the post-process `apply_shader` path, never binding for regular SDF/sprite draws.
12  - Via AskUserQuestion: chose to **patch the engine** (vs a Lua-only sprite hack); image-as-CONTENT = build both luminance- and pattern-driven modes to compare; **480×270 deferred** ("we'll do this later manually, piece-by-piece").
13  
14  **Engine patch — aux sampler binding for the draw path (`Anchor2/engine/src/anchor.c`):**
15  - Patched the `COMMAND_SET_UNIFORM_TEXTURE` case in the command loop (~line 4693) to ALSO immediately `glActiveTexture(GL_TEXTURE0+unit); glBindTexture; glUniform1i(loc, unit)` on the active draw shader, in addition to the existing post-process stash. The batch renderer only touches unit 0, so a mask on **unit ≥ 2** persists across the frame's draws.
16  - Built with `Anchor2/engine/build.bat` via **PowerShell** (cmd-batch output is swallowed in MINGW bash; the first bash attempt didn't actually rebuild — confirmed by the binary timestamp). Copied `build/anchor.exe` → `ricochet-template/anchor.exe`.
17  - Documented as a cross-project memory (`reference_anchor2_aux_sampler_draws.md`).
18  
19  **Image-as-SHAPE (tiled icon masks) — `sprite` + `sprite_field`:**
20  - Added `sprite` shape kind (kind 3): each grid cell stamped with a chosen icon's silhouette (its alpha), tiled, the effect fills it. `shape_mask` gained a `cell_uv` param; the sprite branch returns `textureLod(u_shape_tex, vec2(cell_uv.x, 1-cell_uv.y), 0).a` (Y-flipped for gl_FragCoord vs texture origin). Icon bound on **unit 2**. Sidebar ICON picker (`icon_names`, `current_shape_icon`).
21  - User feedback: keep this "icons as background" mode (with the default color recipe it reads as icons-bg + black noise; only good with `ramp`). Wanted (a) **filled icons** to compare, (b) a **field mode** where the icon is sized by the field (the circle-analog), (c) a **SPACING** slider.
22  - Added `sprite_field` (kind 4): icon **sized by the per-cell field `fc`** (circle-analog — big where bright, gone where dark). Relabeled `sprite`→`icon (bg)`, `sprite_field`→`icon (field)`.
23  - **Filled icons:** extended `tools/fetch_icons.mjs` to also fetch each Tabler `-filled` variant (22 resolved), interleaved as `<concept>_filled` into `icon_names`.
24  - **SPACING:** first version insets the icon within a fixed cell → user noted it *shrank* icons instead of adding gaps. Reworked so SPACING enlarges the grid **pitch** (`size /= 1-spacing`, sprites only) while `shape_mask` insets the icon by the same factor — the two cancel, so the icon keeps its absolute size and only the gap grows. Relabeled CELL SIZE → **ICON SIZE** for sprites.
25  - `sprite_field` restricted to **filled icons only** (an outline scaled down by the field collapses to a thin ring); switching into field mode snaps `current_shape_icon` to its `_filled` counterpart (`icon_names_filled`).
26  
27  **Image-as-CONTENT (effect over real images):**
28  - New third screen "IMAGE" (Tab). User supplied `girl.png`/`boy.png` (opaque anime illustrations, RGB no-alpha). For PATTERN mode's stencil, fetched a transparent **wolf-head silhouette** (`game-icons:wolf-head` via Iconify→resvg, CC-BY 3.0, credited in `assets/images/CREDITS.txt`).
29  - **LUMINANCE** mode: the image's own luminance is the field → dither + recolor; CONTRAST tone-spread slider. **PATTERN** mode: the selected pattern fills, masked by the image's alpha. Shader: `u_image_field` flag. `effect_image` draws via `layer_push` scale (engine draws textures at native size; the photos are ~2600px).
30  - Follow-up requests: (1) circles/icons when the effect fills the shape, (2) the **moving pattern** driving the image's dither (vs static).

5   
6   ## Summary
7   
8   Continuation of the `ricochet-template` visual-experiments work (follows "Visual Experiments 3"). This session did two big things: (1) made the entire effect system + UI read at **480×270 "rough" mode** (the SNKRX low-res render target), and (2) **generalized the whole template into a reusable, resolution-agnostic package** (`require('ricochet')`) with a **two-skin UI toolkit** — mirroring how snkrx-template was generalized. Ended with a slimmed minimal `main.lua`, frozen v1 dev galleries, trimmed assets, a folder-agnostic `run.bat`, and a rewritten `CLAUDE.md`.
9   
10  **Alignment + key architecture facts (up front):**
11  - Read the VE-3 summary + `ricochet-template/.claude/CLAUDE.md`. Confirmed via `anchor.c` that layers are created at `game_width × game_height` (4899) and the draw shader renders into the layer viewport (3975), so at game-size 480×270 **`gl_FragCoord` runs 0..480/0..270** — the dither/shape grids become true 1-logical-pixel cells, upscaled 4× by `rough` (nearest) → crisp pixel-art dithering with **zero shader changes**. The low-res effect work was therefore a *visual tuning + culling* pass, not a rewrite.
12  - Engine constraint: a single global `game_size`; low-res is a **mode switch** (flip the config), not a side-by-side. User chose "do the whole thing as 480×270, fork based on a setting."
13  
14  **`run.bat` made folder-agnostic:** rewrote it to derive its own folder name (`for %%I in ("%~dp0.") do set "GAME=%%~nxI"`) so a copied/renamed fork (e.g. `mini-looper/`) runs without editing run.bat. Verified the cmd idiom in a renamed-copy probe (the MINGW `cmd /c` mangles `/c` → use `cmd //c`).
15  
16  **Icons — picked + fetched (HackerNoon):**
17  - Wrote `tools/compare_pixel_packs.mjs` (Iconify collection API). Data: Pixelarticons 813 names but **no filled style on Iconify** (only `-sharp`); HackerNoon Pixel Icon Library (`pixel` prefix) has clean outline + `-solid` pairs for every core game/HUD icon (heart/star/coin/trophy/crown/fire/bolt/…), 248 solids. Decision: **HackerNoon** (filled requirement decisive; pixel-native 24px grid stays crisp at 16/24 where downscaled Tabler softens). The user confirmed twice by eye ("the 5th column" = HackerNoon).
18  - Fetched 36 HackerNoon icons (outline + `_filled`) via new `tools/fetch_pixel_icons.mjs` → `assets/icons/pixel/`; fill-based, integer-grid viewBox `0 0 24 24` → crisp at native 24. Also fetched **Pixelarticons** (34, base/outline only — user fills manually) via `tools/fetch_pixelarticons.mjs` → `assets/icons/pixelarticons/`; it has the weapon/RPG shapes HackerNoon lacks (sword/shield/potion/skull/gamepad/target).
19  
20  **Fonts — research, downloads, trio chosen:**
21  - Researched pixel/bitmap fonts (WebSearch). Downloaded **Departure Mono** (OFL), **Cozette** (MIT/OFL), **Pixel Operator** family (CC0, dafont) + on-hand Ark/Fusion(latin)/Lana/monogram/m5x7/FatPixel/BoldPixels into `assets/fonts/`.
22  - **Chosen trio (fonts-in-context bench): body Ark10 · header PxOpB (PixelOperator-Bold) · mono Monogram (+ PxOp8 chrome).** User requirement: the *text* font must be CJK-capable (Ark/Fusion/Lana qualify); headers can be Latin-only.
23  - ⚠️ **Critical finding:** the engine font atlas bakes only **ASCII 32–127** (`FONT_FIRST_CHAR`/`FONT_NUM_CHARS` in `anchor.c:976–995`), so **CJK does not render yet regardless of font file**. Treated CJK-capability as a forward-looking *selection criterion*; extending the atlas is a deferred engine task.
24  - Per-font vertical nudge: Monogram "sits 1px low" — added a `font.voff` field applied in the text helper (`voff = -1` for Monogram).
25  
26  **The rough (480×270) low-res build — `main_rough.lua` + `rough_ui.lua`:**
27  - `main.lua` got a `ROUGH` flag forking to `main_rough.lua` (480×270 / scale 4 / `rough`). Built `rough_ui.lua` — a low-res pixel-scale port of the Ricochet UI language (filled-rect hairlines crisp under nearest, corner brackets, inverted-fill active states); the 1-logical-px line *is* the crispest pixel-art line, so the chrome translated directly.
28  - Screens (Tab): FONTS/BODY + FONTS/DISPLAY specimens, ICONS 3-pack compare grid (PA/HN/TB column labels), then **mock game screens showing fonts in context**: HUD (bars/pips/ability slots), MENU (panel + slider + segments + buttons), SHOP (item cards), TITLE (3×-scaled title + menu selection), COMPONENTS (kitchen-sink: checkbox/radio/toggle/stepper/field/dropdown/tabs/tags/badges/keyhints/table/sparkline). Live **font-role swap** (B/H/M keys) so the same UI re-renders per candidate.

6   ## Summary
7   
8   Continuation of the `ricochet-template` visual-experiments arc (follows "Visual
9   Experiments 4"). This session built the **component catalog** — all of reference
10  sheet 02/03/05's UI elements as default builds in BOTH skins — then ran a **UI-API
11  ergonomics pass** (uniform returns, contract + layout helpers), then **made the
12  package genuinely fork-ready** (moved the core into `ricochet/`, labs into `lab/`),
13  wrote docs (README + CLAUDE.md fork guide), and **published the GitHub repo**
14  `a327ex/ricochet-template`.
15  
16  **Orientation + the key finding (up front):**
17  - The work target was `ricochet-template/` (not `RETICLE/`). The user's framing —
18    "both smooth and rough skins," "cards in the rough lab but not smooth" — is the
19    two-skin toolkit in `ricochet-template/ricochet/` (`skin_smooth.lua` +
20    `skin_rough.lua`). `RETICLE/` is a smooth-only scaffold; its `design.md` +
21    `reference/visual_reference.html` and the numbered sheets in
22    `E:/a327ex/Ricochet/reference/` (02 GENERAL UI ELEMENTS, 03 TYPOGRAPHY, 05 GAME
23    OBJECTS) are the visual reference only.
24  - **Audit finding:** the composites the user remembered (cards/hud bars/etc.) were
25    never ported into either skin — they existed only as *screen-local functions*
26    (smooth in `showcase.lua`: `card`/`hud_bar`/`badge_row`/`ability_bar`/`segbar`/
27    `tooltip`; rough inline in `main_rough.lua`'s `draw_shop`/`draw_hud`). So the task
28    = promote them into real `ui_*` widgets in both skins + show them in screens.

6   ## Summary
7   
8   Sixth visual-experiments session, all in **snkrx-template** (E:/a327ex/snkrx-template). Brought two systems over from ricochet-template: (1) **replaced snkrx's old edition system with ricochet's four-axis effect system** (pattern × color × dither × shape), wired to snkrx's named palette; (2) **standardized + demonstrated the UI toolkit** to ricochet's conventions. Also built a clickable **F5 effect inspector** and **migrated the F3 sound tuner** onto the toolkit. Task 1 (effects) is fully done; Task 2 (UI) has conventions + tuner done, with component-parity + showcase left for next time.
9   
10  **Task 1 — effect/dither system replacement (big-bang atomic):**
11  - Ported `ricochet-template/ricochet/effect.lua` → `snkrx/effect.lua` and `ricochet-template/assets/draw_shader.frag` → `snkrx/assets/draw_shader.frag`. The old `edition.lua`, `gradient.lua`, `symbols.lua` were deleted; `geometry.lua` (triangulate) kept.
12  - The core design decision (resolved by the user): **don't preserve the edition "shimmer arbitrary base color" concept at all** — the SNKRX breathe is reproduced via the ricochet system's existing axes: `pattern='organic'` (the Balatro noise the editions used) sweeping a `color='mix'` between two palette tokens, with a dither. Entities are "just drawable like a rectangle via effect_* calls."
13  - Every drawable now carries a **`.spec`** (a four-axis table) instead of `.edition` + `.color`. Draws bracket `effect_set(layer, self.spec)` / `effect_clear(layer)` (or use `effect_rectangle`/`effect_circle`/`effect_rounded_rectangle`/`effect_image` single-call wrappers). Added `effect_rounded_rectangle` + `spec_color(spec)` (the `edition_base_color` replacement — resolves a spec's primary token for FX/particle tinting) to effect.lua.
14  - Flashing (the white hit-flash) uses a shared `flash_spec = {color='solid', color_a='text'}`: `local spec = self.flashing and flash_spec or self.spec`.
15  - Migrated all 8 entity/carrier files: player, seeker, wall, projectile, area, beam, flicker, prop (+debris+polygonal), plus fx tint callers. `fx.lua` itself was edition-free (only callers computed tints). Carriers inherit `caster.spec` (so a player's attacks breathe in the player's color); pass `spec={...}` to override.
16  - **Multi-color-draw gotcha**: a draw with several distinct hues under ONE effect_set (beam's white tip-flash over its colored body; area's white outline over translucent fill) gets recolored to a SINGLE recipe color. Fix: bracket the sub-draw that must keep a different color SEPARATELY (effect_clear then a fresh effect_set) — done for beam tip + flicker body flashes. Alpha IS preserved (`vColor.a`), so translucent fills stay translucent.
17  - **Palette**: `snkrx/palette.lua` rewritten to add the effect adapter (`palette` name→object table, `palette_token_names`, `palette_token_index`, `palette_init`). The shader's `u_palette[13]` bumped to **`u_palette[26]`** (snkrx's 18 canonical tokens + 8 legacy `snkrx_*` tokens — the user confirmed snkrx_blue (teal) ≠ blue (navy), so all 8 legacy tokens were added). `gradient_palettes` removed.
18  - **Default specs** defined in `snkrx/init.lua`: `player_spec` (snkrx_blue↔light_blue), `enemy_spec`/`attack_spec` (red↔orange), `rock_spec` (yellow↔orange), `wall_spec` (`{color='none'}`, flat), `flash_spec`. Used close hue-neighbor pairs for a cohesive "one color rippling" breathe.
19  - **Engine**: snkrx's `anchor.exe` was dated 2026-05-24, predating the 2026-05-30 aux-sampler draw-path patch needed for sprite-shape masks. Recopied the patched build from ricochet-template (same shared Anchor2 engine).
20  - The ramp API was verified to support a future ramp editor: `spec.ramp` (a list of 2–8 token names), `u_ramp_tokens[8]`/`u_ramp_count`, `color_ramp(f)` interpolation — all intact post-port. A ramp editor would just mutate `spec.ramp`.
21  
22  **F5 effect inspector (`snkrx/effect_lab.lua`):**
23  - A Ricochet-gallery analog requested by the user, but as an INSPECTOR with **clickable shapes**: a canvas of ~5 sample drawables (rects, rounded-rect, circles), each with its own spec; click one to select it; a left inspector panel edits THAT shape's spec live.
24  - Inspector controls: `ui_field` cyclers for pattern/color/dither/shape, `ui_swatch_row` pickers for color_a/color_b, `ui_slider`s for scale/speed/contrast/param/param2 (per-pattern). New shapes default to the `palette_breathe_partner` breathe.
25  - Toggled by **F5** (`toggle_effect_lab`); structured like the F4 gallery (active flag, `effect_lab_update` queues widgets, `effect_lab_bg_draw` composites the canvas). Sprite shapes excluded from the lab's shape cycler (need a bound icon texture).
26  - Built two new widgets for it: **`ui_field`** (the `LABEL value [‹][›]` cycler, Ricochet name) and **`ui_swatch_row`** (wrapping palette-token color picker; swatches forced flat via a solid override spec).
27  
28  **Nomenclature fix:** the UI's `ui_breathe` boolean was renamed to **`ui_color`** ('solid' | 'mix', defaulting to 'mix' — the green/blue breathe the user liked). The F4 gallery's O key now cycles the color recipe; status line reads `color: solid/mix`. The breathe-partner table `ui_breathe_partner` was promoted from `paint.lua` to `palette.lua` as **`palette_breathe_partner`** (shared by the UI + the inspector).

4   # Visual Experiments 7
5   
6   ## Summary
7   
8   Closed out Task 2 of the snkrx-template UI work — built the remaining "missing" widgets, brought the F4 gallery to full component parity, audited and modernized the existing showcase pages, then made the whole template genuinely fork-and-go: folder-agnostic `run.bat`, a clean `main.lua` (scaffold preserved separately), synced docs, and a new `README.md`. All work in `E:/a327ex/snkrx-template`; engine is Anchor 2.
9   
10  **Task 2B — component parity audit + seven new widgets:**
11  - Diffed snkrx's UI set against ricochet-template's full 34-widget roster (29 per-skin from `ricochet_use_skin` + 5 shared in `ricochet/ui.lua`). Verdict: most already at parity or snkrx-superior (snkrx uniquely has `tooltip`, `modal`, `rich_text`, `label`, `swatch_row`, real-keyboard `text_input`). Flagged 3 off-style/skip (`ui_frame`, `ui_brackets`, `ui_dropdown` — hairline/blueprint or non-functional stub), and a set of genuine gaps.
12  - User answered "all of them" + "extend ui_slot" for ability cooldown. Built in SNKRX style (filled rounded chips, drop-shadow edge, green state markers, circular knobs, scale-pop juice — NOT ricochet's blueprint hairline look):
13    - **`ui_slot` extended** (`snkrx/ui/widgets.lua`): added `cooldown` (0..1 → bottom-up translucent dim sweep, stencil-clipped to the rounded slot via the same idiom as the selected-outline), `cooldown_text` (caller-owned remaining count, centered — deliberately NOT fabricated from the fraction the way ricochet's `ceil(cd*9)` does), and `key` (top-left charcoal keycap pill, drawn last so it stays legible over the icon + sweep). Slots passing none are byte-for-byte unchanged.
14    - **`ui_toggle`** (widgets.lua): rounded pill track + circular white knob that slides; off = charcoal track / grey knob left, on = green track / white knob right; reuses the shared `form_control_interact` machine; returns `{ on, clicked }`.
15    - **`ui_hud_bar`** (widgets.lua): `[icon tile][ui_bar][value]` composed from `ui_item_icon` + `ui_bar` + `ui_text`; optional `id` threads `ui_bar`'s HP-juice tween.
16    - **`ui_keyhint`**, **`ui_status_tag`**, **`ui_counter`**, **`ui_segbar`** (`snkrx/ui/primitives.lua`, all pure-draw): keycap chip + label; buff/debuff chip (`[glyph] LABEL [value]`, label colored as the buff, built on `ui_label`+`ui_rich_text`); vertical stat_chip (small-caps label above a `[glyph value]` box); chunky segmented meter (the pips cousin, fractional-floor cell widths like `ui_tabs`).
17  - Preferences chosen: charcoal backing pill for the slot keycap (vs bare muted glyph); white knob both toggle states (track color signals on/off).
18  
19  **Task 2C — gallery showcase parity:**
20  - Diffed all 17 existing gallery pages vs the element set. Only `ui_field` + `ui_swatch_row` (built earlier but only used in the F5 lab / F3 tuner) + the 7 new widgets + the `ui_tabs` `segment` variant were undemonstrated.
21  - Added 3 new pages to `snkrx/ui/gallery.lua`, registered at the TOP of `ui_gallery_pages` (the "newest first → opens on latest work" convention): **controls** (`ui_toggle` ×3, `ui_field` cyclers with wrapping value lists, `ui_swatch_row` palette picker with live selection), **hud kit** (`ui_hud_bar` ×3 HP/MP/shield with HP carrying the juice, `ui_counter` row, `ui_status_tag` buff row), **ability bar** (`ui_slot` cooldown+key row showing ready/cooling/locked states, `ui_segbar` ×2, `ui_keyhint` row).
22  - Added the `segment` variant beside the default `tab` variant on the existing tabs page. No `main.lua` change needed — the page table drives everything.
23  
24  **Existing-page audit + fixes:**
25  - Verified the 17 pages against the toolkit's own Design Rules: no-thin-borders holds, selection markers follow the documented idioms (slot stencil, card 2px, list/skillset 2px green left stripe), font rules consistent, every widget colored draw routes through `ui_*` wrappers.
26  - **One real latent bug found:** `ui_heading` / `ui_sublabel` in `snkrx/ui/core.lua` still passed `edition = o.edition` to `ui_text`, but `ui_text` reads `opts.spec` since the Task 2A rename — so a spec override handed to a heading was silently dropped, and the rule's `ui_rect` got the wrong field name. Fixed all spots `o.edition` → `o.spec` + the docstrings. The gallery uses raw `gallery_section_label` so it never hit it, but the F5 lab / F3 tuner / real games do.
27  - **Composite modernization** (user picked the two targeted swaps over a full rebuild): HUD ability bar now uses `ui_slot`'s `key` keycap instead of a separate caption row, with one slot mid-cooldown (`0.55`, "3") to show the sweep in a real layout; the pause screen's status-effects panel now builds rows from `ui_status_tag` chips instead of hand-drawn colored-text + duration pairs.
28  - Left alone (defensible): `page_compose` hand-rolls a tooltip, `page_shop` uses `ui_label` for gold, section labels draw raw (calm scaffolding vs breathing widgets).
29  
30  **Generalizability + `run.bat`:**

I've reviewed the visual experiments 1-7, and now I need to check how the SNKRX template folder turned out before tackling the same exercise for the emoji art style. I'll look at the SNKRX template structure first, then examine the emoji games like Emoji Ball Battles and Emoji Aimer to understand the emoji art approach I need to replicate in a template folder.

I've reviewed all seven Visual Experiments summaries and now I'm checking the snkrx-template folder output before surveying the emoji games.

1    # snkrx-template
2   
3   A starter [Anchor 2](https://github.com/a327ex) project for building **attacks in
4   the SNKRX / Orblike / Invoker visual style** — punchy 2D action with a living,
5   breathing palette. It ships three reusable pieces:
6   
7   - five **attack carriers** (projectile · area · beam · flicker · prop),
8   - a four-axis **effect system** (pattern × color × dither × shape), and
9   - a SNKRX-style **UI toolkit** (panels, slots, bars, cards, HUD widgets, …).
10  
11  Fork the folder, edit `main.lua`, build your game.
12  
13  ## Quickstart
14  
15  ```sh
16  ./run.bat        # runs main.lua — run.bat resolves its own folder name
17  ```
18  
19  `anchor.exe` (the Anchor 2 engine) is committed, so the template runs out of the
20  box. `main.lua` is the clean player-only scene; for the full demo (every carrier
21  + the dev tools) copy **`main_scaffold.lua`** over `main.lua`.
22  
23  ## Fork & use
24  
25  1. **Copy the whole folder** and rename it (`cp -r snkrx-template my-game`).
26     `run.bat` derives its own folder name, so the copy runs immediately — no edits.
27  2. **Boot** is three lines at the top of `main.lua`:
28     ```lua
29     require('anchor')({ width = 480, height = 270, title = 'my-game', scale = 3, filter = 'rough' })
30     require('snkrx')             -- attack carriers + effect system + UI toolkit, in one require

I've reviewed the VE 1-7 summaries and the snkrx-template documentation, so now I'm diving into the emoji art style games to understand the design patterns—primarily looking at Emoji Ball Battles and Emoji Aimer, with the emoji-ball-battles folder serving as a reference library for past emoji game implementations.

I've loaded the snkrx-template CLAUDE.md and now I'm examining the structure of Emoji Ball Battles and its reference games.

I'm looking at the reference materials for the emoji art style—there are several past emoji games in the reference folder like emoji-merge, emojunky, and various super emoji titles that show the design patterns I should follow. I also need to check the effects documentation to understand what visual effects are available.

The user wants me to build an emoji-template starter project similar to how snkrx-template was created—capturing the emoji art style with Twemoji-based visuals and specific juice/FX/UI conventions. But this is a big multi-session exercise, so I should first get familiar with the emoji style by reading through the docs and reference games, then propose a plan and ask the user about scope and direction before diving in.

One key thing to note: Emoji Ball Battles runs on Anchor v1, while the templates are Anchor 2, so I'll need to clarify whether the emoji-template should be built on Anchor 2. I'll start by reading the effects documentation and design.md, scanning the main.lua structure, and surveying the reference games to understand what visual and style elements define the emoji aesthetic—things like Twemoji assets, background colors, juice patterns, and FX conventions.

I've got the full picture of the VE arc and snkrx-template now. I'll explore the past emoji games in the reference folder and review the core docs to understand the emoji style.

Now I'm diving into the main.lua file for Emoji Ball Battles to understand its structure, art style, and how emojis are rendered with effects like drop shadows and outlines. I'll also check the design documentation to see what conventions they're using.

I've found a rich effects catalog. Now I'll examine Emoji Ball Battles and Emoji Aimer's design doc.

1    # Emoji Aimer — design summary
2   
3   ## Loop
4   Click emoji targets in a timed round to reach a score target. Shop between rounds for build items. Soft-fail only — runs always advance.
5   
6   ## Round
7   - **Timer-based**, fixed duration.
8   - 1 point per hit, plus event-driven points from items (chains, pebble drops, resource collisions, multipliers).
9   - **Score target** displayed in HUD.
10  - **Cash Out** appears when target met → ends round, banks remaining time. Staying in past target = the player's bet that their build will out-earn the time-bank.
11  
12  ## Combo
13  - One meter. Consecutive hits; breaks on miss.
14  - 10 tiers (0 / 10 / 20 / ... / 90).
15  - **Drops are deterministic**: each tier specifies "every Nth kill drops a coin/gem/crown" — counters persist across tiers.
16  - Each tier-up unlocks new behavior (score multipliers, bonus targets, combo-decay freeze, flow state, etc.). Specifics TBD by iteration.
17  - Combo is the skill-expression layer: climbing it unlocks excitement, never punishment.
18  
19  ## Gold (round-end payout)
20  Score is in-round; gold is calculated at round end as itemized lines:
21  - **Cleared** — flat default amount.
22  - **Time Banked** — bonus per second remaining at cash-out.
23  - **Interest** — Balatro-style: $1 per $N held, capped.
24  
25  No score-over-target line. The cash-out-vs-push decision is the score-extension mechanic.
26  
27  ## Shop
28  Primary build vector. Items modify event triggers — point per chain, per pebble hit, per resource collision; conversions; multipliers. Tag families (HUNTER / MAGE / MONK / MERCHANT / etc.) make build identity legible. Reroll + sell prioritized; lock + tier offerings deferred.

Emoji Ball Battles uses a Twitter emoji color palette with outlined layers and drop shadows to create that distinctive emoji art style. I'm diving into the main.lua draw pipeline to understand how these outline and shadow layers composite together, and checking the visual polish logs for more details.

4   # EBB Visual Polish
5   
6   ## Summary
7   
8   Session focused on visual improvements for Emoji Ball Battles: sky background, cloud system, and wall styling. Made significant framework changes along the way.
9   
10  **Sky System:**
11  - Added sky gradient background (sky blue at top -> off-white at bottom)
12  - Background gradient moved to early_update so children action functions draw on top of it
13  - Added cloud.png and sun.png assets to the game
14  
15  **Cloud System with Poisson Disk Sampling:**
16  - Clouds distributed using Poisson disk sampling algorithm (ensures even coverage without gaps or overlaps)
17  - Implemented directly in arena constructor using inline anonymous objects (object!, set, action, flow_to pattern)
18  - User corrections: use full function names not aliases (set not Y), verbose variable names (position not pos, index not idx)
19  - Clouds are subtle (alpha 0.5-0.6), slowly drifting right, wrap around when past arena edge
20  - Sun feature was implemented but removed as unnecessary distraction
21  
22  **Critical Bug Fix - YueScript Global _anon_func_N Collision:**
23  - Error: attempt to index a number value (local self) when creating colors with alpha parameter
24  - Root cause: Both color.yue and main.yue had inline conditionals that compiled to global _anon_func_0
25  - color.yue rgb_to_hsl had (if g < b then 6 else 0) which compiled to global _anon_func_0
26  - main.lua hit_circle class also had inline conditional compiling to _anon_func_0
27  - When rgb_to_hsl called _anon_func_0(b, g), it got main.lua version expecting (self, white)
28  - Fixed by extracting inline conditional in color.yue to local variable h_offset = if g < b then 6 else 0
29  
30  **Layer System Expansion:**

I'm solidifying the visual architecture for the emoji-ball-battles system: starting with downscaled Twemoji assets, layering in a sky gradient with procedurally-placed clouds, then applying per-layer outlines and shadows for depth, followed by recoloring effects, wind animation for plants, and the full suite of hit effects with spring physics and flash overlays, plus digit and letter rendering for damage numbers.

Now I'm waiting for the Explore agent to finish surveying the reference games, but in the meantime I want to dig into emoji-aimer's main.lua to see how the visual style evolved there—it's likely the most recent iteration. I should also check what other emoji games exist in the codebase this year since the user mentioned the style appears across multiple titles: emoji-ball-battles, emoji-aimer, emoji-ball-bounce, and possibly others.

I'm realizing that Emoji Aimer is already built on Anchor 2, and it borrowed its visual style from emoji-ball-bounce, which also uses Anchor 2 with that Twitter emoji palette, sky gradient background, and the shadow and outline shader pipeline. So there's already precedent for this emoji aesthetic working on Anchor 2.

The lineage is becoming clearer: the v1 games (emojunky-one through Emoji Ball Battles) were built on YueScript→Lua, while emoji-ball-bounce and Emoji Aimer represent the Anchor 2 ports of that style. An emoji-template would naturally build on Anchor 2 using these existing projects as reference.

I should look at the main.lua files for both emoji-ball-bounce and emoji-aimer to see how large they are and understand how the layer pipeline was ported over, since that's the core of the visual system.

I found that Emoji Aimer is already on Anchor 2 with a style ported from emoji-ball-bounce, so now I'll examine emoji-ball-bounce to understand the origin of that style port.

1    # Emoji Ball Bounce — design
2   
3   A score-based roguelite. EBB-style physics arena (balls bouncing, optional
4   weapons, energy systems lifted from Emoji Ball Battles). Artifact-style
5   card layer over the top: items attach to balls, improvements sit in the
6   border zones, spells, units, etc. Balatro-style chips × mult scoring at
7   the round level.
8   
9   ## Core loop
10  
11  1. **Draft** before each run: build a starting deck.
12  2. Each **round**: draw N cards, play with available mana, then watch the
13     physics arena run for a fixed timer. Cards generate score from events.
14  3. **Round end:** total score = chips × mult (per-round resolution). If
15     ≥ threshold, advance; threshold scales each round. Otherwise lose.
16  4. Between rounds: shop / draft more cards. Threshold escalates.
17  
18  ## Physics
19  
20  Lifted from Emoji Ball Battles. Open arena (no chamber by default —
21  chambers spawn from cards). Balls bounce, can collide with each other.
22  Optional weapons attach to balls. Gravity on, restitution < 1 plus EBB's
23  energy systems (wall energy boost, floor unstick, ball-ball energy
24  tracking, weapon-weapon boost). Energy must remain stable in **all
25  configurations** — including single ball with no weapons.
26  
27  ## Scoring
28  
29  **Per-round chips × mult.** No default scoring; every chip and every mult
30  comes from a card. Two pools (chips, mult) accumulate over the round

Looking at the emoji-ball-bounce main file, it's a fairly compact 26KB implementation that represents the cleanest version of the emoji style on Anchor 2 — probably the right foundation for building a template. I'll scan through the pipeline and helper functions to understand how it's structured.

I found that emoji-ball-bounce's main.lua is only 26KB and appears to be the original Anchor 2 port, so I'll read through it as a potential template for the emoji version.

I've got a solid grasp of the Anchor 2 style now. I'm waiting to hear back from the Explore agent about the reference games, but in the meantime I want to dig deeper into emoji-aimer since it's the most recent and fully-featured Anchor 2 emoji game—it should have the complete set of ported effects like hit circles, particles, damage numbers, combo text, UI elements, and shop systems all implemented.

Searching through the main.lua file to map out its structure...

Emoji Aimer has built out a comprehensive visual effects and UI system with hit feedback layers, particle effects, damage numbers, combo tracking, resource physics for collectibles, a complete shop interface with all the standard components, screen transitions, and companion characters.

It also includes weapon variety with different types like bows, guns, swords, and boomerangs. I'm waiting for the Explore agent to finish surveying the reference games so I can write up my final analysis and proposal. In the meantime, I want to check the draw pipeline and layer structure in Emoji Aimer to see how it compares to Emoji Ball Bounce.

I'm waiting for the Explore agent to finish running in the background, but in the meantime I'll quickly check the emoji-aimer assets folder to get a sense of how many emoji assets are being used, and also take a look at the download-emoji skill since it handles Twemoji asset downloads and could be relevant to the template setup.

I'm checking the asset inventory for emoji-aimer and noticing it has a bunch of PNG emoji assets, some fonts, and shaders, but no audio files which is a bit surprising. I'll set that aside for now and wait for the Explore agent's survey to come back with more details about the reference games. While I'm waiting, I should start thinking through what the response structure should look like.

I want to recap what the VE arc exercise was and how snkrx-template turned out, then characterize what makes the emoji art style distinctive based on what I've gathered. From there, I can frame building an emoji-template as the same kind of exercise — essentially an Anchor 2 starter that carries forward the emoji visual style. The key decisions I need to lay out as questions are whether to start fresh from emoji-ball-bounce and emoji-aimer or port from the existing EBB, what systems the template should actually ship with (render pipeline, palette, effects, UI, sounds, wind, cursor juice, transitions), whether the four-axis effect system even applies to flat emoji colors and outlines, and how to handle the emoji asset pipeline with the download-emoji skill and a starter set.

So the emoji-template would bundle together the layered outline and shadow compositing for emoji rendering, the Twemoji palette, spring and flash hit effects, a particle catalog covering hit circles, particles, stars, dashes, fire, and explosions, damage number popups, cursor juice, camera shake and handcam conventions, sky and cloud backgrounds, the plant wind system, the full emoji-aimer UI kit with HUD chips and panels, circle wipe transitions, sound conventions, and the emoji-fetch tooling — probably with a gallery or demo scene included.

The user wants me to synthesize what the emoji style consists of, map out what the exercise would look like, and prepare a batch of framing questions with options and recommendations. I'm waiting for the Explore agent to finish running in the background so I can incorporate its findings into my response. I could do some light verification work while the agent finishes—checking EBB's asset details or draw pipeline specifics—but that risks padding the response. The real issue is that ending my turn now would leave the user with an incomplete final message, which violates the guidance that everything needed must be in the closing text. So I should keep working on useful, non-duplicative checks while waiting for the agent to complete, then deliver the full synthesis once it reports back.

I've gathered what I need on EBB's sound conventions and I'm waiting for the Explore agent to finish. Rather than write my synthesis now and have it interrupted when the agent completes, I should wait for that report to arrive so I can incorporate everything in one cohesive response. I could use TaskList or TaskOutput to check if the agent has finished, or I could leverage the Monitor tool to wait for completion—though the system should notify me automatically when the background agent finishes anyway. Let me try checking the task status to give the agent a bit more time while I verify what's available.

Actually, I think the better move is to synthesize what I already have now without waiting for the full agent report. I've got substantial material: the effects documentation (which already covers the four reference games), the main game code, the emoji-ball-bounce implementation, inventory mechanics, palettes, layer pipelines, and sound setup. The agent's findings will mostly add texture to what I already know about those older games. I'll do the synthesis now and then add any genuinely new details once the agent completes, keeping the follow-up brief.

So the plan for this turn is to deliver: the VE arc and nkrx-template outcome, the emoji art style across the games, a proposed shape for the emoji-template exercise, and batched framing questions with options and recommendations — all aligned with the user's preference for thoroughness and batched questions.

Actually, let me check if the agent has finished yet by pulling the task list. One quick lookup could get me the report now if it's done.

# Emoji Art-Style Survey — for an `emoji-template` starter

## TL;DR

All ten projects are LÖVE games by the same author, and they descend from **one continuous house style** that has been re-implemented across four engine generations. The style is consistent enough that `emoji-aimer/main.lua` and `reference/yue/main.yue` are essentially the same look in two languages. The defining recipe is: **Twitter/Twemoji PNGs drawn at low internal resolution and upscaled with nearest-neighbor, composited through a layer pipeline that auto-derives a drop-shadow pass (offset down-right) and a chunky black outline pass per layer, over a flat dark-charcoal background, with springs + white-flash + screen-shake juice on every interaction.**

I need to correct something about the agent's report — Emoji Ball Battles is actually on Anchor v1, not v2 as claimed. The reference/yue folder contains the archived YueScript version from before the game was converted to Lua back in February 2026. The agent seems to have confused the framework versions.

Looking at Emoji Aimer though, that one is correctly identified as Anchor v2 — the `require('anchor')({...})` pattern and procedural calls are definitely v2 idioms, and the main.lua composite location the agent cited is roughly accurate.

Now I'm ready to frame the key decisions for the user: whether to seed a fresh template from emoji-ball-bounce's clean Anchor v2 setup and port over the effects and UI pieces from emoji-aimer, or take a different approach to consolidation.

For the toolkit itself, I'm thinking about what should ship in an `emoji/` package — the render substrate with palette and layer pipeline that auto-derives shadows and outlines, the juice systems like hit effects and screen shake, the FX set covering particles and explosions, and text popups for damage numbers.

There's also the question of scope: whether to include the full UI kit (HUD chips, panels, shop tiles, tooltips) in the first session or defer it, plus decisions around emoji asset tooling, sound banks, and optional decorative systems like plants and wind. The structure would mirror snkrx-template, exposing everything cleanly through a single `emoji/` package.

For scaffolding, I'm thinking a demo file, F-key galleries for effects, documentation, a folder-agnostic run script, and git setup—probably all yes. Resolution defaults to 480×270@3, which is already settled. The bigger question is whether this is an exploration phase or consolidation: the emoji style feels locked in and well-documented, so this reads more like a generalization and port job than pattern discovery.

Session 1 should focus on scaffold, render pipeline, and core functionality, then iterate from there—though there's room for polish passes like shadow variants and outline improvements along the way. I'll batch the questions with a proposed plan and stop there, keeping everything in chat with thorough CLAUDE.md-style communication.

One thing to clarify: the agent mislabeled the archived YueScript EBB as Anchor 2, but it's actually running on Anchor v1 (the `an` god-object). The style content is correct, but this matters for the template decision—the template needs to be Anchor 2, and EBB code will need translation while emoji-aimer and emoji-ball-bounce code mostly won't.

Now I'm looking at what snkrx-template provides: a fork-and-go starter with the snkrx package, carriers, four-axis effects, UI toolkit, clean scaffolding, and dev tools. I need to map out how the emoji-template would have an analogous shape, then synthesize what the emoji art style actually is—pulling together the house style recipe, its lineage, where the best references live, and noting those corrections about which codebase versions are involved.

Then I'll frame what running the same exercise would look like for the emoji template, followed by batched questions with options and recommendations to keep things readable and thorough without bloat.

The user wants to start with a fresh emoji-ball-bounce skeleton and eventually layer in dither effects on the emoji style, which means porting over the four-axis effect system with adjusted defaults and visual testing. They're leaning toward a cleaner, Persona-style aesthetic with manga-dot or halftone patterns for background noise rather than gritty dither. The priority is nailing the UI, visual effects, and action juice.

For sounds, they want to pull action sounds like jumps and dashes from reference games like emojunky and super-emoji-box, mix in some from emoji-ball-bounce, and incorporate the F3 sound tuner panel from the snkrx template. On the declarative pipeline API question, "seems good" most likely endorses building the declarative registry version where the game declares its layers and the composite gets generated automatically, rather than keeping the explicit hand-rolled approach visible in main.lua.

The user's confirmed the visual style is visual-only, and now there's a key shift: I need to build this in Anchor3, not Anchor2 — that's what's currently served on the website. They want me to get up to speed on Anchor3 and understand the minor changes from Anchor2, then come back with a proposed plan of attack and the session-1 design brief. From what I recall, Anchor3 is a 3D extension of Anchor2 using Box3D, with session 1 already complete covering physics3 bindings, a layer3 renderer, and a playground toy.

The key architectural detail: Anchor3's engine now powers the live site's wasm build, so any engine changes there can affect production — this is a continuous-work grant situation. I need to read Anchor3's reference plan first. One notable fix in Anchor3: stroke shapes now use an inset ring approach (fixed in 2026-07-11) where rectangle_line and similar shapes hug the inside with exact pixel thickness, whereas Anchor2 still has the old centered-ring bug. For a 2D emoji template, the "very small/minor changes" likely means the 2D API stays the same but the engine has fixes like this stroke behavior, and building in Anchor3 means using the engine build from Anchor3 rather than Anchor2.

Now I need to check Anchor3's folder structure and documentation to understand where the emoji-template should live and how to set up the framework files properly.

7   ## What this is
8   
9   Anchor 3 extends the Anchor 2 engine with **3D game support** (tier: "primitive-3D" —
10  flat-shaded instanced primitives matching the physics shapes, no asset pipeline). Physics is
11  **Box3D** (Erin Catto, released 2026-06-30), vendored and pinned. The 2D engine underneath is
12  a full copy of Anchor 2's C engine + Lua framework; all 2D functionality keeps working — 3D is
13  additive (new layer type + `physics3_*` / `layer3_*` style APIs beside the 2D ones).
14  
15  **⛔ SILO RULE (amended 2026-07-07): never modify `E:\a327ex\Anchor2\` from work here.**
16  Reading Anchor2 for reference is fine. The website silo was deliberately pierced by owner
17  instruction on 2026-07-07: **a327ex.com's anchor.wasm now builds from THIS engine**
18  (`a327ex-site/renderer/tools/build-web.sh` points at `Anchor3/engine/build-web-engine`), and
19  `a327ex-site/renderer/games/anchor3-playground/` is a copy of `playground/` for the in-engine
20  `::game` embed. Consequences: engine C changes here can affect the LIVE SITE once the site
21  bundle is rebuilt — after touching `engine/src/anchor.c`, run `./build-web-engine.sh` and treat
22  site deploys with the usual care. Anchor2 remains untouched and is NOT a sync target.
23  
24  **Read `reference/plan.md` first** — roadmap, decisions log, and current status.
25  `reference/anchor3_assessment.md` is the original feasibility assessment (scope rationale).

27  ## Origin & divergence
28  
29  - `engine/src/anchor.c` — copied from Anchor2 2026-07-07, then extended (3D math, physics3
30    bindings, 3D layer). Anchor2's copy is the 2D ancestor, NOT a sync target.

I'm tracking the evolution of Anchor3, which builds on Anchor2 by incorporating the engine and framework from a July 2026 fork, then layering in 3D additions and various engine refinements like per-layer batch orthographic rendering, fixed-size layers, and some stroke shape fixes that I'm pulling from memory.

For building an emoji template in Anchor3, the setup copies the framework files and builds the executable from the engine source, giving us the same 2D API as Anchor2 but with those accumulated fixes—and the key advantage is that a game built this way could eventually be embedded on the website since it runs on the same engine. Now I need to verify a few critical things: whether the engine build is current, whether the framework includes all the audio DSP support that the emoji games depend on (specifically the sound wrapper for the F3 tuner), and whether that DSP functionality made it into Anchor2's mainline before the fork date.

Looking at the snkrx-template docs, the per-voice DSP wrapper was already in the Anchor2 engine source around May 2026, and since Anchor3 copied from Anchor2 in July 2026, it should be there—I'll grep the source to confirm. Same check for the aux-sampler draw patch needed for sprite shape masks in the four-axis effect system, which also landed in May. I also need to verify the framework folder has all the 2D modules, and since the user wants to port the effect system with different visual styles, I'll need to ensure the draw_shader replacement works and that the per-glyph shape sub-rect patch is present. 3D modules too, probably safe to include everything — plus anchor.exe from the build folder, a folder-agnostic run.bat, and assets like the shader effects (shadow, outline, recolor, grayscale from emoji-aimer, plus draw_shader for the effect system), Twemoji PNGs, fonts, and bounce sounds. The emoji package itself will have the init, palette, pipeline for layer registry, hitfx/juice effects, and damage numbers.

I need to be careful about how the four-axis effect system's draw shader works — it replaces the engine's default shader, so every draw call routes through it. In snkrx-template, UI and entities all use it, and in the emoji template the pipeline adds outline/shadow/recolor as separate post-process shaders on top. The draw shader should default to passthrough so emoji PNGs render normally unless an effect spec is applied, similar to how snkrx handles it with color='none'. Now I'm wondering if the effect system's shader will conflict with the white hit-flash effect. I need to dig into the actual implementation to understand how the flash effect works in Anchor 2. Let me check the emoji-aimer source around where the drawing happens and see how the color parameter behaves with the shader, then compare it to how EBB v1 handled the flash parameter.

My plan is to search the Anchor 3 engine for the audio sampler markers, list out the framework files, examine the emoji-aimer flash mechanism in the draw code, and then synthesize everything into an up-to-speed summary with a concrete design brief and questions for the session. The scope is clear now — I need to port the entire four-axis effect system with updated defaults and careful attention to how it all fits together.

I'm also noticing that the manga-dot halftone aesthetic the user wants is actually already baked into the four-axis system through the shape axis with circle grids and cluster-dot dithers, which was even mentioned in the original brief. So porting the system gives us that direction for free, and the tuning sessions will dial in the final look. Beyond visuals, I need to pull in the action juice from the emoji-box work — the movement verbs like jump squash, dash, wobble, and charge-up animations that sell the feel.

For the sound side, I'm porting the tuner module from the template with its DSP wrapper and volume overrides, making sure it integrates with Anchor3. The priority for this first session is getting the core pipeline, juice, and effects working; the UI kit is important but probably belongs in its own follow-up sessions since it's such a big piece. I could build the tuner with minimal drawing capabilities instead of waiting for the full UI toolkit, which would let it ship sooner. Now I'm running some verification checks.

Anchor3's engine has the DSP wrapper functions and the aux-sampler texture command path set up, with a fresh build from yesterday. The framework includes all the 2D modules plus 3D extensions. I'm checking the specific aux-sampler patch details around line 6227 where the texture uniform command binds immediately for the draw path as of the May 30th update.

Since Anchor3 was copied on July 7th after that patch landed, it definitely has the fix included. Now I'm looking at the emoji-aimer flash mechanism in its main.lua file around lines 2385-2412 to get the details right for the brief.

Engine checks pass and Anchor3 has the necessary DSP sound wrapper and aux-sampler draw patch from yesterday's build. Now I'll verify how the white hit-flash mechanism works on Anchor 2 image draws.

I'm looking at how the layer_image function handles the color parameter in Anchor 2's engine—it appears to flash the image by replacing the RGB values while preserving the alpha channel, rather than doing a standard multiply-tint. I need to check the API documentation to confirm whether this is the intended behavior for the color argument.

No matches found

Looking at the `layer_image` function signature and how emoji-aimer calls it — the function takes layer, image, x, y, color, and flash parameters, and emoji-aimer is passing nil for color and a white flash value, so the engine does support a dedicated flash parameter for rendering.

Now I have what I need to put together a response. Anchor3 is essentially Anchor2 with 3D additions layered on top, keeping the 2D API intact and using the same procedural v2 architecture. The engine has all the features required for a 2D emoji template: per-voice DSP wrappers for audio processing, aux-sampler draw patches for effect sprites, native flash support on layer_image, fixed-size layers with layer_draw_into for site embedding, and the recent inset stroke shapes fix. Since it's the live-site engine, template games can embed directly on a327ex.com without porting, but I need to be careful not to modify Anchor2 during this work since engine changes in Anchor3 could affect the live site — though I don't anticipate needing any C-level changes since all the shaders are post-process .frag files and draw-shader replacements handled on the game side.

For the practical setup, I'll copy the framework/anchor/ directory with all its modules and grab a fresh build of anchor.exe from 2026-07-17. The session plan mirrors the VE approach: Session 1 focuses on scaffolding the render substrate and core juice, with an emoji-template/ folder containing the Anchor3 engine, a folder-agnostic run.bat, assets like shaders from emoji-aimer plus a starter Twemoji set, fonts, hit1.png, and EBB sounds. The emoji/ package will have a declarative layer registry with auto outline and shadow derivation, juice systems for springs and HitFX with shake and handcam effects, and a suite of effects like hit circles, particles, and stars. I'll wrap it up with a demo scene showing a bouncing emoji ball, clickable targets, and cursor interaction to showcase the system.

Session 2 brings in the four-axis effect system from snkrx-template tuned for emoji, plus a gallery and inspector for testing the halftone/manga-dot direction. Sessions 3 and beyond cover action juice for movement verbs like jump and dash, damage numbers with keycap recoloring, transitions, and finally a Persona-style UI kit with HUD chips and panels, plus an F3 sound tuner.

For the initial session, I'm setting up the folder structure with emoji-template containing a batch runner, the Anchor3 build and framework, assets, and the emoji package loaded via require. The emoji/init.lua file aggregates the palette, pipeline, juice, effects, and sounds modules, with emoji_setup handling palette installation and layer setup.

Now I'm defining the Twemoji color palette as globals matching the game's style — whites, blacks, grays, and a full spectrum of named colors like star_yellow, bronze, and sky gradients. The pipeline.lua file declares the layer registry with background, game, effects, and UI panel layers, each with their own outline and shadow settings.

The emoji_render function processes each layer, derives shadows from all shadow-enabled layers, generates outlines, then composites everything bottom-to-top with the shadow offset at (4,4) and outlines positioned beneath their respective layers. Configuration handles shadow offset, shader values for the new gray tone, and outline thickness through pixel size. I'm also considering a recolor bucket helper for digit recoloring but might defer that. Still working through whether the pipeline should own the camera attachment or if it defaults per layer like in the emoji games.

I'm settling on keeping structural things explicit in main.lua like snkrx-template does, but making the composite loop itself generated since it's mostly boilerplate—the real structural knowledge is the layer order, which stays visible in the declaration. Now looking at juice.lua conventions for hit effects, where the hitfx helper attaches hit and squash springs plus a flashing flag, with directional squash handling...

Adding more effect modules... Plants could be a nice decorative touch for session 1 or pushed to session 3 depending on scope. I should keep the brief focused and let him drive the iteration, flagging a few key decisions: whether the sky/clouds and plants fit in the first session, whether main.lua should start as the demo scene (mirroring how ricochet evolved), and how to structure the palette—either simple globals now with a token adapter layer later, or building the token table from the start.

On the dither and persona angle, the four-axis system already has the halftone building blocks built in—the shape axis gives us manga screentone grids, and cluster-dot patterns work like newsprint. His persona direction (clean, high-contrast, stylish patterns) maps naturally to pattern choices like waves or truchet tiles, combined with shape grids and minimal two-token color recipes, keeping dither off or very coarse. The port strategy is to bring the whole system but default to clean settings, then eye-test from there.

I'll structure the response as: first, get him up to speed on the key deltas, then lay out the proposed session arc, follow with the design brief for session one covering approach and interfaces, and batch any open questions at the end. Keeping this as a design brief rather than diving into code, then waiting for his feedback.

The user approved my approach, so I'm moving forward with the sky gradient, clouds, shared shadow layer, and the demo scene as planned. Now I'm setting up the project structure by creating the emoji-template folder and copying over the necessary anchor framework files and executable.

For session 1, I need to gather all the source assets: shaders from emoji-aimer (shadow, outline, recolor, grayscale), fonts like LanaPixel and FatPixelFont, a starter set of Twemoji PNGs including slight_smile, star, and cloud, the hit1 sound effect, and various audio files from EBB like ball_wall and concrete impact sounds. I'm checking which specific emoji PNGs and sound files exist across the different projects to pull the right ones. Actually, I need to check the exact filenames from emoji-aimer's assets, then port over its visual effect classes like hit circles and particles, plus the cursor implementation. I'm also trying to figure out where the sound effects wrapper pattern comes from—emoji-aimer doesn't have audio assets, so it must be borrowed from snkrx-template's approach to handling sfx and volume control. Looking at whether Anchor2 has poisson disc sampling built in — the emoji_effects doc mentioned it's available through the engine, so I should check the framework's math utilities. For the bouncing ball, I'm porting from the existing emoji-ball-bounce implementation which already uses Anchor 2, keeping the spring-based squash mechanics on collision but removing the energy hop system since we're cutting those out.

For the physics itself, I'll use the same setup as the original — restitution 1 with no friction and continuous collision detection so the ball bounces convincingly. It'll gradually lose energy over time due to Box2D's inherent energy leak, but that's acceptable for a template demo; games can add their own compensation if needed. I'll keep it simple: copy the ball physics, add the squash handler on wall hits, and let players reset with backspace.

Actually, a ball that eventually stops bouncing feels incomplete. The cleanest approach is to remove gravity entirely — with restitution 1, the ball maintains constant speed and bounces forever, which means the squash effect triggers on every wall hit. That's perfect for showcasing the juice visually without the decay problem, and it still captures the weight and impact feel. , so I'll set up a simple speed floor on wall contacts—if the ball dips below 200, scale it back to 240 as a demo scaffolding trick. For the target, I'm porting the hit cascade from the emoji-aimer: click detection within radius triggers a spring pull, flash, hit circle, particles, emoji sparkles, screen shake, and damage application; on death, scale up those effects and respawn after a delay. I need to extract the exact cascade values from the emoji-aimer's target hit and die methods. Then I'll write a fresh declarative registry for the emoji layers and rendering pipeline.

Now I'm thinking through the shader and camera setup—pixel size uniform, shadow config, and a handcam system similar to the other games. The camera attaches around the game and effects layers during the draw queue, while UI stays unaffected. I need to figure out how the camera attachment works at queue time versus composite time.

Looking at how emoji-ball-bounce handles it: the host brackets its world-space draws with camera_attach and camera_detach calls in main.lua, so the camera logic stays on the host side rather than in the pipeline. That means I can drop the `camera?` flag from my registry—just keep it simple with name, outline, and shadow. The shake effect gets baked into the game layer's framebuffer, so the shadow naturally shakes with the world, which is the right behavior.

Now I'm checking the layer_draw_from signature... So the composite order places shadow right after the background, then alternates outline and layer for each content layer—game outline, game, UI outline, UI. UI layers get outlined but skip the shadow pass entirely, while in emoji-ball-bounce only game and effects contribute to shadows, not the UI. Registry flags control which layers participate in which effects.

Now I'm setting up the pixel-size uniform for the outline shader at initialization, then registering two fonts—'lana' at size 11 and 'fat' at size 8—matching the emoji-aimer naming convention. The setup flow should have the main config loaded first via anchor, then emoji initialization follows, though I need to clarify whether the require itself handles the setup call or if that comes separately. I'm thinking through whether emoji_setup should install a default layer stack, or if emoji_layers can be called separately to define the stack. The pattern I'm settling on is having emoji_layers as a registry function that builds the stack, with emoji_setup calling it using default definitions unless the host provides custom ones. For the initialization flow, require('anchor') sets up the window, require('emoji') loads all the modules and registers assets, then emoji_setup installs the default layer stack—though I'm keeping the camera creation in main.lua since that's structural and follows the snkrx-template pattern.

Actually, I'm reconsidering: the cleanest approach is to keep structural things visible in main.lua. So require('emoji') just loads the code and assets at require time, then main.lua explicitly calls emoji_layers with the stack definition visible there, and draw() wraps the rendering in camera brackets and calls emoji_render(). This avoids hiding a default stack and makes the architecture clearer. So the flow is: require('emoji') loads palette globals, shaders, fonts, images, sounds, and the fx/juice/cursor classes, then main.lua defines the layer stack...

Defining the layer stack... I'm weighing the visual style: aimer's approach of charcoal outer background with sky gradient inside the board frame versus bounce's full-screen sky gradient with walls framing it. For this demo, I'll go with the EBB style—full sky background with wall frame and drifting clouds—since it showcases both the charcoal palette and the sky effect, though bounce's full-screen gradient is also a valid direction. ls on the game layer get outlines and shadows, so I'll make them thin visual frames (around 12 pixels) with thicker physics colliders that extend offscreen for proper collision detection.

For clouds, I'll check if the framework has a Poisson distribution helper for even spacing, but if not, I'll just scatter 3-5 clouds randomly across the arena — simple enough for the demo, though the original used Poisson for better coverage.

Now I need to gather the Twemoji assets: slight_smile.png for the ball, star.png for sparkles, cloud.png for clouds, backhand_index_pointing_up.png for the cursor, dash.png for dash particles, and I'll pick a different face emoji for the target. I also need the hit1 spritesheet (96x48) and sound effects like ball_wall.ogg and various concrete and revolver shot sounds from the emoji-ball-bounce assets.

For the audio, I'm mapping ball_wall to wall bounces, concrete variants to target hits, and I'll grab player_death.ogg from EBB for when the target dies — the revolver shots probably won't be needed. I need to figure out the volume levels for each sound. Now I'm looking at the juice module structure — I need to set up hitfx initialization that creates springs for hit and squash effects, then implement the hit trigger that pulls the spring and flashes the entity. I'll also need a squash function based on the bounce pattern, a wall hit intensity curve, and camera shake helpers using Anchor2's API.

For the remaining utilities, I'm checking bounce for the shake_handcam call and aimer for shake_trauma to get the exact API names, then porting slow_time which manipulates engine time scale. The punch zoom effect from aimer needs to be adapted as a camera punch function. Finally, I'm reading through aimer's cursor class to port a trimmed version that keeps the generic behaviors like sway, squash, click juice, and flash, while dropping game-specific states and figuring out how to hide the system cursor through the engine.

Now I'm planning a batch read of key sections from emoji-aimer: the image and font loading, the effects classes, cursor implementation, target hit and death cascades, slow time function, shake and punch usage patterns, and the assets list.

I also need to check the snkrx-template for the sfx wrapper in the init file and understand the sound loading API, then cross-reference the Anchor2 framework docs for the sound, image, spritesheet, layer, timer, and random helper APIs.

Once I've gathered all that, I'll write out the files and syntax-check each Lua file with lua54 before creating a starter CLAUDE.md document that covers the orientation, design brief rules, file map, and roadmap for the project.

I've got the hit cascade and slow_time mechanics working with the slow_mo table and time scaling, plus the punch-zoom effect.

I'm checking the sound system API—sound_play takes DSP parameters directly and sound_load returns a handle I can use with sound_get_path for tuning. Now I need to verify a few framework functions: layer_rectangle_gradient_v for gradients, mouse_position and mouse_delta for input tracking, and I'm looking into the mouse API details. I need to verify a few more utility functions exist in the framework—the random helpers, font registration, image loading, and layer drawing functions for text and images. I should also check if there's a poisson distribution function in math.lua, or I'll implement rejection sampling inline if needed. Once I confirm these are available, I can write out the files.

I need to verify a couple more function signatures that weren't in the earlier grep results — specifically `set_time_scale` since `slow_time` depends on it, and I should double-check the parameters for `sound_play` to see if it takes the bits and sample rate divisor arguments.

I need to check the actual engine binding name — it's `engine_set_time_scale`, not `set_time_scale`. The emoji-aimer implementation probably used a Lua alias or their framework version has a wrapper function, so I should look into the Anchor3 framework to see if there's a `set_time_scale` compatibility layer.

framework/anchor/init.lua:23:      sync_engine_globals()          -- refresh time/frame/etc. mirrors

I've verified all the APIs through the framework wrapper, so I'm ready to start building. I'm setting up the template structure with the executable, framework files, and asset directories needed for the emoji project.

Now I'm gathering all the shader files and assets from the existing projects—fragment shaders for effects like outlining and recoloring, font files, and emoji images from emoji-aimer and emoji-ball-bounce. For the demo target face, I'm checking what EBB assets has available and planning to use the no_mouth emoji with a hit-state variant that swaps to no_mouth_hit when the target gets hit.

Setting up the audio files next—ball collision sounds, concrete impact variations, gunshot samples, and a player death sound. Then organizing the Lua modules for the emoji system: initialization, color palette management, the rendering pipeline, juice effects, visual effects, cursor handling, and sound management with a tuning stub for adjusting audio parameters.

Now I need to verify those assets exist in the EBB repository and start writing the actual code. I'm setting up the palette with all the color constants following the naming convention from aimer, making sure to avoid the `gold` collision by using `medal_gold` instead.

For the pipeline, I'm building a declarative layer registry system that takes a list of layer definitions with optional outline and shadow flags, then generates the corresponding layer globals and framebuffer objects automatically. The emoji_render function will handle compositing everything together. Finishing the outline derivation logic...

I'm working through the composite order now—specifically where the shadow should render in the layer stack. It looks like the shadow needs to draw right after the background layer, before the content and outline layers, so the sequence would be background, then shadow, then game outline, then game content. The shadow composites right before the first layer marked with shadow or outline, which keeps the order consistent across different emoji types—background first, then shadow, then game and UI layers. I'm implementing this by iterating through the layer definitions and drawing the shadow layer as soon as I hit a flagged layer.

Writing composite logic... Writing juice module functions... So `set_time_scale` affects both the engine-side global time and locally scales dt for downstream timers and tweens, while the slow_time tween itself runs on an unscaled timer to naturally stretch recovery duration in real time. The score_chip_timer gets updated with the scaled dt, which means the recovery intentionally takes longer when time is slowed.

Now looking at the juice module structure — there's a global slow_mo scale factor and a juice_timer that gets created at require time. The `slow_time` function tweens that scale factor, and `juice_update` applies the scaling to dt before passing it to the timer. The `camera_punch` function uses the juice_timer to tween camera position and zoom...

Defining camera punch animation...

I need to verify that the camera object actually has a zoom field that works with camera_attach, and check what fields are initialized in camera_new. Then moving into hitfx setup, which initializes a spring system on entities with hit springs that have specific damping and stiffness values.

Adding more spring properties... The `collection_update` helper will manage the fxs list lifecycle, with spawn wrappers inserting new particles. I'm deciding to keep the core four particle classes and express dash and star variants as instances of the base emoji_particle with configurable parameters like angle mode and image, rather than creating dedicated classes. Moving on to cursor.lua next. Setting up the sounds module with a tuning map for audio parameters, loading sound assets, and organizing volumes by gameplay event name so callers can pass both the sound handle and its corresponding volume together.

Now I'm setting up the init file to require all the core modules like palette, pipeline, juice, and effects, then deciding whether to use a global images table or individual globals like the existing games do.

Loading the starter emoji set as globals — slight_smile_img, star_img, cloud_img, and the aimer pointer — then registering the spritesheet and fonts for the engine.

Setting up the main anchor configuration with the window dimensions and scale factor.

Now I'm requiring the emoji module and defining the arena dimensions at 240x200, centered with 10-pixel thick walls. Physics initialization sets up gravity and collision detection between the ball and walls. I'm organizing the rendering layers for background, game objects, effects, UI, and cursor with outline and shadow effects.

There's a potential naming conflict between the cursor class and cursor_layer, but I'll keep them distinct—the aimer class will be named `cursor` and the layer will be `cursor_layer`. I'm also setting up the main camera with shake effects configured for subtle vibration on impact.

For the entities, I'm pulling the wall class from the bounce prototype with its visual frame and static physics body. The ball class keeps the core mechanics like squash deformation on wall hits and spring physics for ball-to-ball collisions, plus I'm adding wall impact sounds and a re-kick system that normalizes velocity if it drops below a minimum threshold. The target class is a simplified version with just position, radius, and health points.

Now for the target's hit and death sequences: when hit, it swaps to a damaged face sprite for a quarter second, shows an HP bar below, and triggers a cascade of effects including spring physics, a flash, particle bursts with yellow streaks and star emojis, screen shake, and a concrete impact sound. On death, it spawns more yellow streak particles and stars with a larger shake, then respawns at a random arena position after a timer. I'm also adding background clouds that drift across the arena.

For rendering the clouds with transparency, I need to pass a tinted color to the layer drawing function—something like white with reduced alpha to get that semi-transparent effect. I'm checking how the color parameter works in the layer system to make sure the tint multiplies correctly with the cloud image.

The cloud sprite is 512 pixels from Twemoji, so I'll scale it down to about 40 pixels wide when drawing. For the background, I'm layering a full-screen color rect first, then drawing the sky gradient over the arena interior, with clouds on top to keep everything soft and cohesive.

For the demo interaction, clicking triggers a hit check on the target if the cursor is within its radius, otherwise nothing happens. I'm also adding keyboard shortcuts—'b' to spawn extra balls, 'r' to reset, and skipping debug features for now to keep the demo focused.

Writing update logic... Deciding whether to use dt or sdt for the cursor — it should feel responsive during slow-mo, so I'll stick with dt and add a comment explaining why. Then I need to handle collisions (ball-wall interactions with sound and physics, ball-ball springs), process click hits on targets, clean up the destroy queue, and verify that collection_update properly removes dead entities or if I need separate filtering logic like the wall drain did.

For the draw function, I'm layering the background with a gradient sky and clouds, then attaching the camera to render walls, balls, and targets in world space, followed by effects in the same coordinate system.

I need to make sure the camera is attached to both the game and effects layers so the aimer's visuals align properly. Also checking that fonts are registered globally as `fonts.main` and that layer drawing functions like `layer_circle` are available. Looking at the spring system to understand how `spring_add` works with parameters like initial value, stiffness, and damping.

Now I'm verifying the timer tween function signature and how it handles both tagged and untagged tweens, plus checking the collection update semantics and camera zoom field. Then I'll copy over the necessary assets and confirm the EBB has the cloud.png and player death assets before writing everything out.

14      if e._dead then
15        table.remove(list, i)
16      else
17        local fn = e[method]
18        if fn then fn(e, dt) end
19      end
20    end
21  end

118:  local zoom = c.zoom*(1 + z_off)

138:  local zoom = c.zoom*(1 + z_off)
144:  return (x*cos_r - y*sin_r)*zoom + c.w/2, (x*sin_r + y*cos_r)*zoom + c.h/2
160:  local zoom = c.zoom*(1 + z_off)

Everything checks out—the collection update removes dead entries, the camera supports zoom, and all the EBB assets are in place. Now I'm laying out the build sequence: setting up the folder structure and copying the necessary files, writing the batch script to launch the application, creating the emoji package configuration, implementing the main Lua logic, validating the syntax across all Lua files, documenting everything in the Claude metadata file, and finally generating the memory file and final report. I'm considering whether to formalize this as a task list since it keeps coming up.

I'll skip the formal checklist and just move forward with the copy commands.

Now I'm checking the emoji package, starting with the palette.

File created successfully at: E:\a327ex\emoji-template\emoji\palette.lua (file state is current in your context — no need to Read it back)

I should verify that `color_mix` is available in the Anchor3 framework and double-check the `color()` constructor signature to make sure it handles alpha values correctly.

grep: framework/anchor/color.lua: No such file or directory

140:function color_mix(a, b, t)

94:function color_new(r, g, b, a)

131:function color_clone(c)
140:function color_mix(a, b, t)

Now I need to move on to writing the pipeline.lua file, since the color functions and palette are already set up.

I need to verify that timer_after supports an optional tag parameter, since I'm seeing it used both with tags like 'hitfx_flash' and without them. Let me check the actual timer.lua signature in Anchor3 to confirm this works, and also look into what math.circ does.

80:function timer_after(t, delay, name_or_callback, callback_function)

508:function math.cubic_in_out(t)
606:function math.circ_in(t)

Now I'm moving on to fx.lua, where I need to port over the four classes from emoji-aimer but make them more general by adding a layer argument that defaults to the effects_layer global.

I need to verify that `math.sign` is available in math.lua since aimer references it, and I should also check on the `time` global and the input functions `input_pressed` and `input_released` that bounce uses. Now moving on to review sounds.lua and sound_tuning.lua.

File created successfully at: E:\a327ex\emoji-template\emoji\sound_tuning.lua (file state is current in your context — no need to Read it back)

I need to verify that `random_table_element` is actually defined in the framework since it's referenced in a comment, then search for where it's used. If it doesn't exist, I'll need to update the comment or usage in main.lua accordingly. After that, I'm moving on to set up the init.lua aggregator and handle the images.

framework/anchor/array.lua:412:function array.random(t, n, rng)

The function is `array.random(t)`. I need to correct the comment in sounds.lua and apply array.random in main.lua.

Setting up the main demo scene with a boot sequence that loads the anchor, screen dimensions, and emoji module, then defining the arena as a 280x200 centered play space with a 10-pixel frame border, and configuring the physics system with gravity.

Organizing the rendering layers for background, game objects with outlines and shadows, effects, UI, and cursor; setting up dual cameras for main view and hand aiming; binding input controls where space spawns balls, R resets, and clicks interact with targets.

Implementing the core game objects—walls with perfect restitution and no friction, balls adapted from the bounce demo with wall-hit sounds and re-kick mechanics, targets with hit detection and face swaps, and a spawned cursor—then wiring the update loop to sync physics globals, apply juice effects, update cameras, handle spawning and collisions, and process click hit tests against the target.

For rendering, I'm drawing the background with charcoal fill and sky gradient, attaching the camera to render game and effect layers, then detaching to draw UI hints and the cursor on top; when a target dies, a timer respawns it at a random arena position after one second.

Ball-to-ball collisions apply a spring force scaled by combined speed with a quiet sound effect mapped to the same audio file as wall hits but at reduced volume.

Adding the ball-ball volume entry to sounds.lua... Adding camera shake and hit effects... Outlined text rendering with white glyphs and black outlines for the UI layer, using a layer_text function that takes layer, string, font, position, and color. For the ball's hit effects, I'm applying the hitfx_init pattern with spring animations for hit and squash, and on ball-ball collisions using hitfx_hit with reduced intensity but no flash or timer overhead needed.

For ball drawing, I'm using a two-level transform stack — world-aligned squash on the outer layer and rotation plus hit deformation on the inner. On wall hits, if the ball's speed drops below 200, I'll scale the velocity back up to 240 to keep it from getting stuck, though I'm being careful about purely vertical bounces that could flatten out horizontally due to gravity and Box2D's solver behavior.

The collision handler will check the contact normal and velocity after Box2D resolves the bounce — if the ball's vertical velocity is tiny on floor contacts, I'll apply a small upward impulse to prevent it from rolling dead. I'm setting up the collider API with methods for position, restitution, friction, linear damping, and gravity scale.

For the target, I'm debating whether to make it a static circle collider so balls bounce off it, which would create a nice physics cascade where impacts damage the target — that's more visually interesting than just distance-based hit detection.  But that's scope creep; I'll keep it simple with the target as non-physical so balls pass behind it visually.

On the update order: spawning happens after drains and the destroy queue to avoid invalidating handles mid-frame. Click hit-testing goes at the end with input processing, so target:hit effects spawn safely. The cursor updates with unscaled delta time at the end too, which keeps it snappy during slow-mo.

For clouds, I'm using plain tables in a list rather than a class — each one tracks position, speed, scale, and alpha — and I'll spawn four at minimum.

Now I'm setting up cloud spawning with random positions in the arena's top half, wrapping them horizontally when they drift off-screen. I need to figure out the color tinting — checking whether layer_image multiplies the color parameter or uses it as a flash effect, then I'll apply a pre-created cloud tint with the right alpha value.

140    eng.triangle(lyr_handle(lyr), x1, y1, x2, y2, x3, y3, color)
141 end
142 
143 function layer_triangle_line(lyr, x1, y1, x2, y2, x3, y3, color, line_width)

168   eng.rectangle_gradient_v(lyr_handle(lyr), x, y, w, h, color1, color2)
169 end
... [40 more lines]

I'm working through how the layer_image function handles color parameters — the color argument takes a packed integer with alpha support, so I can pass something like a white with transparency. For cloud effects, I'd create a tinted color with reduced alpha and pass that. I need to verify whether the color function with alpha values properly packs the RGBA data, and the flash parameter also expects a packed color integer or zero.

Looking at the other layer functions, layer_circle should already be defined earlier in the file alongside similar shape functions. For layer_text, it takes a layer, text string, font (either a font object or name string), coordinates, and color — fonts.main should be available as a global table set up during font registration, so I can rely on that.

Now I'm ready to write main.lua.

File created successfully at: E:\a327ex\emoji-template\main.lua (file state is current in your context — no need to Read it back)

I need to double-check some API functions I've been using — whether `math.distance`, `math.length`, and `math.sign` are actually available, plus confirming the signatures for `layer_circle` and `layer_rectangle`, and verifying that `fonts` is accessible from the font registration system and the physics functions exist.

Now I'll verify the remaining API names and syntax-check everything.

184:function math.sign(value)
203:function math.length(x, y)
304:function math.distance(x1, y1, x2, y2)
111:function layer_rectangle(lyr, x, y, w, h, color)
115:function layer_circle(lyr, x, y, radius, color)
42:  if fonts then fonts[name] = f end
66:function shake_trauma(s, amount, duration, amplitude)
153:function shake_handcam(s, enabled, amplitude, frequency)
44:function camera_new(w, h)
153:function camera_attach(c, layer, parallax_x, parallax_y)
170:function camera_detach(c, layer)
180:function camera_update(c, dt)

The API names check out, though the fonts table is conditionally created so I need to verify the initialization context. I'm also noticing that `random_angle` isn't showing up in my grep results even though the aimer code uses it, so I should search the framework more broadly for where that function and related random utilities are actually defined.

43:    - images, fonts, sounds, shaders, spritesheets - resource tables
86:fonts = fonts or {}

12534:// random_angle(rng?) - Random float [0, 2π]
12535:static int l_random_angle(lua_State* L) {
14986:    lua_register(L, "random_float", l_random_float);
14987:    lua_register(L, "random_int", l_random_int);
14988:    lua_register(L, "random_angle", l_random_angle);

The engine bindings for random number generation are working correctly. Now I'm running a syntax check on all the Lua files using lua54.exe, keeping in mind that loadfile validates syntax but won't catch undefined globals since those get resolved at runtime.

OK  main.lua
OK  emoji/init.lua
OK  emoji/palette.lua
OK  emoji/pipeline.lua
OK  emoji/juice.lua
OK  emoji/fx.lua
OK  emoji/cursor.lua
OK  emoji/sounds.lua
OK  emoji/sound_tuning.lua

Checking a few remaining correctness issues — making sure `class()` is properly available through the anchor module that's being required, and verifying that the `require('emoji')` path will resolve correctly given how the engine sets up the Lua package path.

Also confirming that image loading happens at the right time before layers are initialized, that the global variables like `width`, `height`, and `time` are set before they're needed by the modules that use them, and that the collision handling for balls and walls works as expected with the framework's normalization of event objects. Both tagged and untagged forms of timer_tween work because the function type-checks the name_or_target parameter. Spring initialization with spring_add handles defaults correctly across emoji_particle and cursor usage. For entity lifecycle, make_entity provides the kill method that fx classes use, and reset_balls kills all balls then spawns a new one — the balls list gets pruned by collection_update on the next frame while the new spawn is added immediately. I should match the bounce pattern and clear the balls list immediately after killing to avoid drawing dead entities for extra frames, even though the destroy queue handles cleanup separately. Then I'm moving on to binding cursor input.

The click input uses polling rather than consuming, so both the main hit test and cursor update see the same pressed state without conflict. For text rendering, I'm passing font objects directly to layer_text, which expects a font with a name property. The camera punch system tweens the camera's x, y, and zoom fields, but I need to verify that camera initialization sets x and y to the center coordinates — otherwise the punch recovery might move the camera from an uninitialized origin.

I should check the camera defaults in camera.lua around lines 44-60 to confirm. The shader files from aimer should work since they're on the same engine family, but I want to quickly verify that shadow.frag and outline.frag reference the correct uniform names the engine binds, and that outline has the u_pixel_size uniform I'm setting. For the arena layout, with gh=270 and ARENA_H=200 centered, that leaves about 35 pixels of margin on the top and bottom.

The hint text sits at gh-16=254, which lands nicely in that bottom margin area. But I'm realizing the hit text uses a middle dot character ('·') which is outside the ASCII 32-127 range that the engine's font atlas only covers — it won't render. I need to swap it out for something like a pipe or dash instead, so the text reads 'click the face | space: ball | r: reset'. Let me make those fixes: ensure reset_balls clears explicitly, keep the hint text ASCII-safe, verify the camera defaults, and do a quick check on those shader files.

I found a few issues: the hint text uses a middle dot character that isn't in the font atlas, reset_balls needs to clear the list immediately like emoji-ball-bounce does, and I'm checking the camera defaults for punch-zoom recovery.

I should write the CLAUDE.md orientation document next, then do a final syntax check on main.lua before attempting a headless verification run. I'm wondering if the `--verify` flag works for emoji-template the way it does in Anchor3, or if I need to use `--balance` like the emoji games did in EBB.

Actually, running the game headless without a proper verify harness is risky since it could hit an infinite loop, so I'll skip execution and rely on syntax checks and API verification instead. I need to confirm that `require('emoji')` resolves correctly to emoji/init.lua like snkrx-template does, and verify that the input functions like `input_pressed` and `input_released` exist in input.lua, plus check that `bind()` and `layer_rectangle_gradient_v()` are available.

main.lua OK

I'm realizing there's something odd about the working directory behavior — the compound command with `cd /e/a327ex/Anchor3` succeeded with grep but then failed on the lua check because Anchor3 doesn't have a main.lua at root, yet the second call without the cd somehow found a main.lua, which suggests the working directory persisted from somewhere unexpected.

The question is which main.lua it actually found — if the cwd is still Anchor3, it shouldn't exist there; if it's emoji-template from an earlier call, that would explain it; if it reset to the base E:\a327ex directory, main.lua wouldn't be there either. I should verify this explicitly with a pwd command and check the full path to be certain which file was actually validated.

/e/a327ex/emoji-template
emoji-template main.lua OK

The working directory is confirmed as emoji-template with clean syntax, so I'm ready to create the project orientation document. I'll write the .claude/CLAUDE.md file covering what the template is, the design-brief rule from other templates, the recommended read order, package structure, the pipeline model, and the roadmap with decisions settled during this session including the Anchor3 engineering approach.

I'll also note the key gotchas like ASCII font handling, sprite centering, layer rectangle positioning, avoiding the exe, and being cautious about engine changes. After that, I'll create a memory file for the project and add a line to MEMORY.md, then wrap up with a final report to the user including test instructions based on the feedback guidelines.

File created successfully at: E:\a327ex\emoji-template\.claude\CLAUDE.md (file state is current in your context — no need to Read it back)

Now I'm saving the project memory and updating the MEMORY.md index, then wrapping up with a final report.

[sealed content withheld: memory]

[sealed content withheld: memory]

I need to add an emoji-template entry to MEMORY.md by creating a new section after the SNKRX-template section, keeping it organized with the other template and game projects.

[sealed content withheld: memory]

The memory file is approaching its size limit, so I need to compact MEMORY.md by condensing entries to single lines and moving detailed information into topic files, while dropping or merging stale entries to get under the target size. I should handle this now before finishing the session-1 report.

Looking at the biggest offenders — the 062026 session entry, project_anchor_website, Anchor3, BYTEPATH++, SNKRX-update, and Steam market entries are all extremely detailed. Rather than verify every topic file exists, I'll focus on these major entries: check if their topic files contain the necessary detail, move anything missing into those files, then trim the index lines to one concise line each. Let me start by reading the full MEMORY.md to see what I'm working with.

[sealed content withheld: memory]

I'm looking at the file size issue with MEMORY.md — it's currently 20.4KB and needs to get under 17.1KB. The 062026 entry is taking up about 4.5KB by itself, with project_anchor_website, Anchor3, BYTEPATH++, and artifact also contributing significantly to the bloat. My approach is to move the detailed session-by-session information into the corresponding topic files, which should already contain most of that content anyway, so I'll need to make sure any trimmed details get transferred over properly.

Before I start rewriting MEMORY.md with compact one-liners, I should check what's already in project_062026.md and project_anchor_website.md to see if the session details are already documented there. If they're missing, I'll append them to the topic files first. Then I can aggressively trim the index entries — for example, the 062026 line could become a single sentence pointing to the topic file with just the key next steps and NDA log references, and the Anchor website entry can be similarly condensed to one line with a pointer to renderer/PLAN.md for the full details.

I'm also scanning through the other entries to identify what can be trimmed: the Code Style section could collapse into a single line under a heading, several project lines (BYTEPATH++, Anchor3, Artifact, Sprite-centered, %d throws, Ghosting, Deliver-in-chat, Radio, ai-assets) can be moderately compressed, and I noticed the Emoji Ball Battles entry has a stale note about "capital O" that should be corrected to "capital I" since Invoker starts with I. The Steam market entry is load-bearing so I'll keep it mostly intact.

I've identified that the index needs compacting, with 062026 and the website renderer being the largest entries. Let me check if their topic files already contain the details before I trim those index lines.

Shell cwd was reset to E:\a327ex

The topic files are substantial enough to hold all the session details, so I can trim the index entries significantly while keeping the file pointers intact. Let me check if project_062026.md actually contains those recent sessions by searching for the key session markers like "Orbiting Missiles" and "Chain Reaction."

I need to trim MEMORY.md down from 21.2KB to around 14-15KB by condensing each entry to a single line while preserving the behavioral hooks and letting the topic files handle the details.

The file size is well under budget with all the dropped details preserved in the topic files. Now I'm putting together the final report—summarizing what was built, the file structure, what to review visually, and how to test it, plus noting that the memory compaction step happened.

The user encountered missing DLLs when running the template, which makes sense since the Anchor engine executable depends on FFmpeg and SDL libraries. Looking at how other templates like snkrx-template and emoji-ball-bounce are structured, they place anchor.exe at the game root alongside the necessary DLLs rather than in a separate build directory.

Since run.bat executes the exe from the template folder itself, Windows will search that directory for dependencies. I only copied anchor.exe without the DLLs, so I need to locate them in Anchor3/engine/build/ and copy them over to emoji-template/.

Exit code 2

I'm noticing that Anchor3/engine/build has six FFmpeg DLLs at its root, but snkrx-template and emoji-ball-bounce don't have any DLLs there—so either their anchor.exe is an older build that doesn't depend on FFmpeg, or they're loading DLLs from somewhere else. Since run.bat changes to the parent directory (E:/a327ex), the DLLs might be sitting at that root level instead.

Let me also check the Anchor2 engine build folder and the playground setup.

Exit code 2

/e/a327ex/Anchor2/engine/build/swscale-8.dll
---playground

I'm noticing the DLL situation doesn't add up—the template executables run fine without FFmpeg libraries present, which suggests they were built before video support was integrated into the engine. The older anchor.exe builds from around June probably predate when FFmpeg linking was added for the website work.

The playground works because it runs the executable from the build directory where the DLLs already sit. For emoji-template, I need to copy those six FFmpeg DLLs next to the anchor.exe at the template root so Windows finds them during the DLL search. I should also verify the exe doesn't need other runtime dependencies—Anchor2's build directory only showed those FFmpeg libraries, suggesting SDL and other components are statically linked.

I'll copy the DLLs and have the user re-run, then update the CLAUDE.md file-map section to document that FFmpeg DLLs must travel with the executable for future reference.

I found that the current Anchor3 engine links FFmpeg with six runtime DLLs in `engine/build/`, which the playground accesses correctly, while the older exes in snkrx-template/emoji-ball-bounce predate that linkage and lack the DLLs. I'm copying them in now.

The demo is working well, so now I'm moving forward with the roadmap. Next up is porting the effect system from the template with four-axis control and setting up clean halftone and Persona defaults, then building out an eye-testing gallery to validate it. After that comes completing the action juice and effects for various interactions like jumps and dashes, followed by building the UI kit in the Persona direction with sound integration. The user's earlier message about porting the whole effect system confirms that's the direction they want. I should recommend option (a) — the effect-system port — as the next session, note that it's a bigger lift requiring eye-testing collaboration, and offer the smaller alternatives (action juice, damage numbers, UI kit) if they'd rather do a quicker increment instead. I could also sketch what the port involves before asking them to pick, so they know the scope.

The user wants to reorder the porting sequence so the UI system comes before the effect system since effects mostly apply to UI. I'm now deciding which UI toolkit to port first, weighing options like snkrx-template's UI toolkit which has the most complete and recently standardized components including core functionality, state management, and rendering utilities.

The snkrx toolkit's architecture is built around the effect pipeline for coloring and visual effects — exactly the coupling the user identified — so the natural approach is to port its architecture (core, state, juice, widgets, gallery) but restyle it for the emoji aesthetic rather than the SNKRX visual language. The Emoji Aimer's UI provides the visual language and raw material for the skin, while ricochet-template's two-skin approach shows how to support multiple visual styles within the same architecture.

The key insight is that the emoji pipeline already provides outline and shadow effects per layer, so the UI toolkit can leverage that chrome substrate directly — the widgets just need to draw onto two separate layers (panel and content) instead of snkrx's single-layer approach, which is a fundamentally different chrome model.

For the port session itself, I'm thinking the focus should be on building the core toolkit and establishing the emoji baseline skin with aimer's look, leaving the stylish persona direction (patterns, halftone fills, angled accents) for later when the effect system is ready. As for the widget roster, starting with a focused set — panel, text, button, icon button, slot, bar, maybe checkbox and slider, list row, card, tooltip, tabs — makes more sense than porting all 34 at once, then expanding to the full gallery once the foundation is solid.

The F4 gallery becomes the testing ground between increments, while F3 sound tuner waits until the toolkit widgets it depends on are ready. For the paint layer, I need to structure the emoji skin's color routing as flat tokens now but design it so the effect-spec overrides slot in cleanly when that system lands — threading the opts.spec through from the start means the next session just swaps the flat fills for effect_set brackets without rearchitecting.

The key question is whether to port snkrx's UI architecture wholesale or build fresh from aimer's foundation. The effect system's visual layer in the emoji template maps to where Persona-style patterns live—panel fills, card backs, bar fills, selected states—so porting UI-first means building paint routing with a spec hook that stays flat initially. For the baseline skin, I'm anchoring to aimer's emoji-UI language since it's the only substantial corpus on Anchor 2: rounded foreground panels with charcoal tones, white content, and outline treatment.

The user approved the plan, so I can move forward with the design brief. I need to lay out the concrete details now: the file structure, the two-layer drawing contract, and how the paint system works—this is what comes before any code gets written. I should read through the core UI files—core, state, juice, paint, and init—plus skim the widgets signatures and look at aimer's HUD drawing code for the skin language. That's maybe 400-500 lines total, which is worth doing to ground the brief in actual interfaces rather than relying on memory alone.

I've got snkrx's core.lua and the full template documentation loaded. Now I'm scanning through paint.lua, state.lua, and juice.lua to understand the exact structure of how these pieces work, then I'll look at Aimer's HUD and shop button rendering to nail down the visual language before writing the brief.

2     ui/paint.lua — effect-pipeline UI coloring.
3   
4     Every UI color is drawn through the four-axis effect pipeline (the same
5     one entities use — snkrx/effect.lua + assets/draw_shader.frag). Instead of
6     `layer_rounded_rectangle(ui_layer, ..., c())`, widgets call ui_rrect /
7     ui_rect / ui_glyph_text, which bracket the draw with effect_set / effect_clear.
8   
9     THE UI'S `color` RECIPE (`ui_color`) — Ricochet's color axis applied to the UI:
10      • 'solid'  — flat token. The UI reads as the flat locked palette: calm
11        chrome behind the breathing game world.
12      • 'mix'    — the breathe (DEFAULT). Each token is mixed with its palette
13        neighbor (palette_breathe_partner), swept by the organic noise field
14        (pattern='organic'). Chrome breathes UP the grayscale ladder (a lightness
15        shimmer); accents breathe to the next hue (the green/blue look). This is
16        what gives the bars + card borders their living gradient.
17  
18    Flip `ui_color` at runtime to A/B the two (the F4 gallery's O key cycles it).
19    `ui_field_scale` (breathe noise density) and `ui_dither` (a dither-mode NAME
20    from the effect catalog, e.g. 'off' / 'bayer4_2') tune the breathe.
21  
22    A widget may pass an explicit per-element spec table as the `override`
23    argument to force a specific effect for its draws (the effect inspector's
24    swatches do this to force a FLAT color); nil override → the token's recipe.

2     ui/state.lua — frame-local UI interaction state.

6       active_id  widget the mouse-down landed on (persists until release)
7       focus_id   widget last clicked (persists until the next click)

2     ui/juice.lua — per-widget retained juice.
3   
4     Immediate-mode widgets are pure functions — they have nowhere to keep
5     a spring, a hover edge, or an eased value. These registries are that
6     place, keyed by the widget's explicit string id. The small, retained,
7     action-based sliver the UI doctrine puts behind an id; everything
8     else stays rules-based.
9   
10    Two registries:
11      ui_juice[id]     = { spring, was_hovered }  -- hover/click bounce
12      ui_bar_juice[id] = { front, back, shown_value, target, target_value }
13  
14    ui_bar_juice holds the v1-style HP bar tween: `front` (fast fraction),
15    `back` (delayed slow fraction — the trailing white 'lost health'
16    chunk), and `shown_value` (the displayed HP number, eased). All three
17    are driven by `ui_timer`, a shared scheduler whose entries are named
18    per bar id, so rapid successive hits debounce cleanly — a named entry
19    replaces the prior one of the same name.

I've got the core components I need: the UI module defines several key functions like ui_sp, ui_ret, and ui_req_id, plus interaction handlers that track mouse input through ui_claim_hot and button state detection. The heading and sublabel elements reference specific fonts and design tokens from the snkrx system, which means I'll need to port those dependencies over.

For state management, I'm pulling ui_state, text capture tracking, and input locking from state.lua, along with mouse position detection that ports directly. The juice.lua registry handles the spring animation parameters and UI feedback—the hover and click sounds are the main consideration here. Since snkrx already has polished UI sounds (bamboo and pop effects) that feel good, I'll copy those for now rather than hunting through the emoji template archives, and flag this as something to revisit once the user decides on the final sound direction. The HP bar tween system is generic enough to port as-is, and I'm moving through the remaining paint utilities next.

The real chokepoint is the drawing API itself—ui_spec_for and the rect/glyph functions. In the emoji two-layer model, I need to route draws to either the panel or content layer, so instead of creating separate function names for each layer, I'll pass a role parameter that widgets already know about. But there's a bigger issue lurking: the aimer used a top-tier panel system for tooltips, which means the toolkit needs to support both a default tier and a top tier, each with their own panel and content layers. I'll need either a global current-tier tracker or explicit tier parameters on each draw operation.

For tooltips specifically, I'm thinking ui_tier('top') and ui_tier('base') calls that bracket the tooltip's drawing operations, with the paint system tracking which tier is currently active. The full layer stack would be ui_panel, ui_content, ui_top_panel, and ui_top_content, all declared once in the main emoji_layers setup rather than scattered across the toolkit. UI layers get outline=true but shadow=false, keeping them visually distinct from the game world shadows — that's a deliberate skin difference from snkrx. For widget interactions, I'm adding scale-pop springs on hover and click, like the emoji-merge button's 0.125 scale pop.

In the two-layer model, widgets scale around their center on both the panel and content layers simultaneously, so I'm creating ui_paint_push and ui_paint_pop functions that handle layer operations on both tiers at once. The emoji font setup registers three typefaces — Lana for main text, FatPixel for big, and Awesome for mid-sized — which the toolkit will use throughout.

For the skin, aimer's chip design uses a foreground rounded panel with naturally-colored emoji and white text that gets a black outline for readability on any background. Panels themselves are either cream or blue with a small rounded radius, keeping the content layer white and natural-colored.

The widget token system pulls from a global emoji palette with defaults like panel fill, blue accent, red for danger, and green for success, while text stays white on the content layer with muted variants using a darker foreground shade. I've settled on which core widgets to port — panel, text, button, icon_button, slot, bar, hud_bar, checkbox, slider, list_row, card, tooltip, plus gallery and the helper components like heading and divider.

For the ui_begin and ui_render contract in the emoji version, I need to drain typed text each frame (pulling from the engine's typed text buffer, which was a gotcha from snkrx), run the ui state frame setup, and update the juice system with delta time before rendering.

Since the emoji pipeline's render pass already composites all UI layers uniformly, I don't need a separate ui_render call — emoji_render handles everything. So I'm keeping just ui_begin in the update phase and letting the draw phase rely on the existing emoji compositing. The input side uses mouse_is_pressed(1) from the engine, which should exist in Anchor3 since snkrx used it from the same engine family.

For the cursor pulse effect on hover, that's optional — widgets could call it themselves during their hover logic, but I'll defer that refinement. Moving to the F3 tuner: it needs list_row, panel, slider, button, and field widgets. Since the tuner uses ui_field for steppers and the field widget is small enough, I'll include it in the core widget pass so the tuner ports cleanly without extra dependencies.

For the gallery on F4, it's a paged showcase with its own background layer separate from the UI layer to avoid full-screen shadow tinting. For the emoji gallery, a full-screen panel fill would work — the outline on a full-screen rect is fine since edges stay offscreen — but I need to use an overlay layer like aimer does to get a fullscreen dim without outlines affecting the content. I need to set up a dedicated overlay layer for the gallery background and future UI elements like dims or scrims — it should sit above the game effects but below the UI layer and have no outline or shadow. I'll add this to the demo's layer stack. I'm also pulling in hover sound effects from the snkrx project and organizing the file structure across several modules, then writing up a conceptual brief covering the approach, interfaces, and functions.

For the skin defaults, I'm deciding on visual state indicators — replacing snkrx's green stencil outline with something like a blue 2px border or fill shift for selected items, keeping the overall structure consistent with what snkrx had for hover effects and tooltips.

I'm settling on blue as the primary interactive accent (matching aimer's score panel and level badge), green for positive/on states like checkboxes, and red for danger states, all using fill shifts and white content rather than borders. Before writing the full brief, I want to present these accent and hover-sound choices as defaults for the user to approve or veto, then wait for their feedback before iterating.

Now I'm mapping out the substantial build ahead: creating a new emoji/ui/ package with 9 files, plus modifications to several existing files like emoji/init.lua, emoji/sounds.lua, and main.lua to handle the layer stack, UI initialization, F4 gallery, and hint text positioning. I'll also need to copy over a couple of sound files and possibly the RectCut utility. Starting with the file plan—I need to port RectCut from the snkrx-template, then move through state.lua and the other UI components.

For core.lua, I'm adapting the snkrx UI functions to work with emoji's styling: headings will use the main font in white small-caps with a white hairline rule drawn on the content layer (outlined to give it definition), and I'll swap in the emoji color tokens like fg_dark for muted text. The 1px white rect approach on the content layer should give a clean, outlined hairline that matches the text treatment.

Now I'm porting the remaining UI modules: juice.lua comes over mostly as-is but needs hover and pop sound references added to a new emoji/sounds.lua file, then paint.lua introduces the tier system and draw functions, followed by primitives (panel, text, divider, label, etc.) and widgets (button, checkbox, slider, list_row, card, field, and more). I'll also create a gallery.lua with an F4-triggered paged view across 3 pages, and tie everything together in ui/init.lua. Finally, I need to wire up the main emoji/init.lua to require the UI module and add those UI sound effects to the sounds file, pulling the audio assets from the snkrx template.

Before I start writing, I should read through snkrx's rect.lua completely and the key sections of primitives.lua and widgets.lua to make sure I port them faithfully—that's a lot of code to review but essential for getting this right. I'm debating whether to include cooldown and key overlays in the slot widget for this pass—they're useful broadly, but the stencil clipping needed for the cooldown sweep creates an outline rendering problem in the emoji style since translucent fills trigger the outline pass. isible. The outline shader only triggers where the center is transparent and neighbors have alpha, so interior edges never produce outlines — only silhouette boundaries get the chunky black border. This means outlines are per-layer silhouettes rather than per-widget, so adjacent widgets that touch will merge their silhouettes together, creating that emoji-like appearance where chips are separated by gaps.

Translucent fills work similarly: a 0.5 alpha fill on the panel layer over a transparent background will fire the outline shader if any neighbor has nonzero alpha, giving standalone translucent elements full-strength black outlines. For the emoji skin I can skip stencil clipping entirely and rely on the layer's alpha compositing instead.

For the cooldown sweep, I'll keep it simple: a translucent plain rectangle drawn bottom-up over the slot area, inset by 1 pixel horizontally to avoid poking past the slot's rounded corners. The slot itself just needs to handle selected/locked/disabled/occupied states plus the optional cooldown sweep and keycap. I can refine the corner handling later if needed.

Now I'm going to look at how snkrx implements rectangles and widgets to understand the pattern better. Examining the file pieces...

7       get_*(r, n) — pure: returns a slice of r without mutating.

I'm getting a clearer picture of the widget patterns now — the stencil masking approach for bar fills, how font objects expose text measurement methods like height and text_width. I should verify whether Anchor3's layer system has the same stencil functions and check what the font API actually provides there.

/e/a327ex/Anchor3/framework/anchor/layer.lua:267:function layer_stencil_mask(lyr)
/e/a327ex/Anchor3/framework/anchor/layer.lua:271:function layer_stencil_test(lyr)

/e/a327ex/Anchor3/framework/anchor/font.lua:27:function font:text_width(text)
/e/a327ex/Anchor3/framework/anchor/font.lua:28:  return font_get_text_width(self.name, text)

I've got the stencils and font metrics ready, so now I'm planning out the `emoji/ui/` package structure file by file. I'm starting with `paint.lua` as the core piece, setting up UI tiers with panel and content layers that will be bound after the main layers are created—but I'm running into a dependency issue where the layers don't exist yet when the emoji module is first required.

The solution is to resolve the layer references lazily through globals using a `tier()` function that checks the current tier and returns the appropriate panel and content layer pair. I'm also sketching out the paint functions like `ui_fill_rrect`, `ui_fill_rect`, `ui_content_text`, and `ui_content_icon` that will handle drawing rectangles, text, and icons to the appropriate layers.

Writing paint functions... Defining ui_text function... For the icon element, I'm drawing just the image centered in a rect without a fill by default, since emojis are already colorful. Then for tooltips, I'm creating a self-sizing component that renders on the top tier with a title in the main font and body text in a darker shade.

Now I'm thinking through the tooltip styling more carefully — the muted text needs enough contrast on the content layer, so I'll keep the title white, description lines white, and metadata in a darker gray. The width should be based on the longest text line plus padding, with a reasonable clamp. For the button widget structure, I'm defining variants like primary, secondary, danger, and ghost, where hover states invert to white fill with an outline-driven appearance.

But there's a tricky interaction with the outline shader — when text is white on a white fill, the outline becomes critical for readability. The outline only renders where there's an alpha boundary, so opaque text interior won't get an outline pass through it. I need to reconsider whether the label should stay white on hover or shift to black on the inverted white fill, since black text on white is more conventional but risks the outline becoming a blob if the outline shader treats it as interior silhouette.

Rather than computing color mixes per frame, I should precompute the hover fill variants at startup — mixing each token color toward white by a fixed amount like 0.35 — and store them in a small lookup table for cleaner, garbage-free access.

For labels, I'm settling on white text across all button variants (primary, secondary, danger) since it reads well even on the foreground fill color, and disabled buttons get a gray fill with dark text.

I'm also sketching out two more components: a ui_icon_button that displays an emoji image instead of text, with a fallback to glyph rendering, and a ui_slot for rounded square tiles that use a dark background so emoji items stand out visually.

For the slot fill, I'm leaning toward using the foreground color as the default since emojis are colorful and read well on lighter backgrounds, with selected states shifting to a blue fill and locked states using gray with a lock indicator.

On the UI bar side, I need to figure out the track styling — a black track with colored fills seems to work best, defaulting to green for emoji slots but red for health bars like in aimer, with the background staying white or using the background color depending on context.

For the other components: the health bar displays an icon, bar, and value text all in a row; checkboxes are rounded boxes that toggle between a dark off-state and a green filled on-state with a white checkmark made from rotated rectangles, with a clickable label to the right; and sliders have a black rounded track with a blue fill and white circular knob that responds to clicks and drag interactions, using a clamped calculation to map mouse position to the value range.

For list rows, I'm thinking about how to handle hover states — maybe a translucent fill on the panel layer that gets an outline, or a solid darker fill that reads well against the charcoal background without looking too chunky.  I'll precompute the hover color as a slightly darkened version of the foreground, and for selected rows use a blue-tinted accent with a left stripe fill (not a border) plus the darker background. Headers get their own variant with a background color and darker text, staying inert. Now moving into ui_card styling with icon, title, description, and footer elements. Gallery will bind its own keys at initialization for self-containment, with the main loop calling ui_gallery_update during the update phase, and the gallery drawing its background as an opaque overlay covering the screen.

The gallery has three pages: controls with UI elements like buttons and sliders, hud displaying labels and bars with demo mechanics, and cards showing selectable card UI with hover tooltips. Gallery state tracks whether it's active, while demo state like checkbox values and HP lives inside the gallery file itself, and I need to add click-guarding so interactions with the gallery don't bleed through to the scene behind it.

I'm setting up the UI initialization to grab typed text input and update the juice animation system each frame, then verifying the engine binding exists. For sounds, I'm adding hover and pop effects with specific volumes and pitch variations handled through the juice system.

Now I need to copy the exact audio files from the template, then restructure the layer system in main.lua to use separate overlay, panel, content, and top panel layers instead of a single UI layer, while making sure ui_begin runs at the right point in the update cycle before click handling. Fonts are set up with text width and height properties for widget sizing. I need to make sure ui_text can access font:text_width() for center/right alignment. Also checking that gallery key bindings don't clash with demo binds — need to verify how bracket keys are named in the engine (likely 'leftbracket'/'rightbracket' following SDL conventions) and confirm the binding setup matches what snkrx-template uses for F4 and page navigation.

184:  -- onto ui_layer. ui_gallery_bg_draw() in draw() composites its bg.
185:  ui_gallery_update(dt)

I've confirmed that the key binding functions work as expected, so I'll have the gallery module bind its own keys at initialization time rather than relying on the host to do it — this keeps things self-contained and the main file cleaner, similar to how the sound tuner handles its F3 binding.

Now I'm writing out all the files in order: paint, state, core, juice, rect, primitives, widgets, gallery, and init; then I'll edit the sounds and emoji modules, update main.lua with the F4 binding and gallery update call, copy assets, run syntax checks, and sync the documentation.

I'm precomputing button colors at the top of widgets.lua by creating fill and hover color tables, using a color mixing function to generate the hover states by blending each color with white. For the checkbox tick, I'm implementing two rotated rectangles positioned at the tick center to create that geometric checkmark effect.

For the slider, I'm using the interaction system to track hover and active states, then calculating the fractional value based on mouse position within the slider bounds and returning both the new value and a changed flag. The field widget combines a label with value display and two small arrow buttons for incrementing and decrementing. For slot cooldowns, I'm precomputing a translucent black color rather than mutating the global black color each frame. List rows accept flexible cell definitions with text, width, alignment, and color properties that flex to fill the available space.

Now I'm thinking through tooltips—measuring width as the maximum of the title and all line widths plus padding, with height accounting for title, line count, and spacing, then drawing it clamped to screen bounds. The gallery widget manages a full page system with background fill, title, page indicator, and multiple pages of widgets, maintaining internal state for checkboxes, sliders, and other controls. There's also a damage mechanic that reduces health and resets it back to 40 when depleted. For the HUD demo, I'm using label chips with available sprite assets like stars, dashes, and clouds.

I'm refining the slot row with occupied slots showing a slight smile, selected states, cooldown timers, and locked slots. Cards display an icon, title, description lines, and a rarity footer pill in different colors. Tooltips appear on card hover at a fixed position. For typography, I'm using the default main font for labels and buttons, while section headers in the gallery use a larger chunky font with white uppercase text and a subtle underline.

Now I need to port the heading and sublabel components from core.lua using the text and content-rule primitives. The require order in ui/init.lua matters—I'm loading rect, state, juice, paint, core, primitives, widgets, and gallery in sequence. Since juice.lua needs the ui hover sound effect and sounds.lua loads before ui in emoji/init.lua, I should add the ui require after sounds to avoid circular dependencies. I'm also verifying that the mouse input functions used in ui_interact exist in the engine's input system, matching what snkrx had.

Let me check the engine family to confirm those input functions are available.

/e/a327ex/Anchor3/engine/src/anchor.c:15007:    lua_register(L, "mouse_is_pressed", l_mouse_is_pressed);
/e/a327ex/Anchor3/engine/src/anchor.c:15008:    lua_register(L, "mouse_is_released", l_mouse_is_released);

Everything checks out. Now I'm writing the package, starting with the verbatim ports and paint chokepoint.

Looking at the widgets module now — it's a substantial one covering button, icon_button, slot, bar, hud_bar, checkbox, slider, list_row, card, and field components. The hover fills are precomputed at the top using color_mix, and I'm relying on the gw and gh globals that main sets up before requiring the emoji module. The tricky parts are handling ui_button's variants and fill mapping, where hover states use a precomputed lighter fill, labels stay white, and disabled states turn gray with a darker foreground label, plus auto-sizing based on the x coordinate.

Icon buttons are simple squares with either an image or label glyph. Slots have a default fill with foreground color, turning blue when selected and gray when disabled, with an occupied icon and a cooldown sweep using a semi-transparent black rectangle that fills from bottom up with a 1-pixel inset. The key indicator sits top-left as a pill-shaped background with a white letter in the big font. Bars use paint stencil wrappers with a black track, green fill by default, and white backing, plus health text. HUD bars combine an icon, bar, and value display. Checkboxes are 12x12 rounded boxes that toggle between gray (off) and green with a white tick mark (two rotated content rectangles), with the label positioned to the right and row interaction. Sliders have a black track with a blue fill and white knob, using ui_interact on the full row rect for a taller hit area, and while active the value updates from the mouse x position. List rows display cells with row fill and a header variant. Cards are rectangles with an icon at the top, title, description lines, and a footer pill, with selected state shifting the fill. Fields have a label on the left, value center-right, and prev/next buttons on the right, returning which button was clicked. The gray token is defined as color(128,128,128).

Now I'm working through the color mixing for hover and selected states—precomputing hover fills by blending colors with white at 40% opacity, using blue directly for slot selection since it reads well over the icon, mixing foreground with blue at 30% for card selected state, and adding a 2-pixel blue left stripe for list row selection with a dark foreground background. I'll keep each widget implementation lean while staying true to the design contract.

Working on the gallery system with F4 toggle, page navigation, and demo state management. The layout is 480x270 with a full-screen overlay using an opaque background color to hide the game underneath. The header displays the title, current page name, and control hints, while the main content area has a 16-pixel margin. Pages are registered in newest-first order following snkrx convention so the gallery opens on the latest content.

The demo state tracks UI component states like checkboxes, sliders, selections, and health values. The controls page showcases buttons in different styles plus disabled states, form elements like checkboxes and a slider, and a selectable list with header row. The HUD page demonstrates labeled chips with icons, health bars with tweening animations triggered by damage/heal buttons, and equipment slots showing occupied, selected, and cooldown states.

For the cards page, I'm rendering three selectable cards with colored footers based on rarity (common gray, rare blue, epic purple) and a tooltip that appears on hover. I'm debating whether to handle key bindings directly in the gallery module or in main.lua — the brief mentions F4 toggle plus prev/next navigation with bracket keys, and while keeping it self-contained in gallery.lua would be cleaner, I should stick with what the brief specifies and bind them in main.

lua instead, then have the gallery read those input states.

Now I'm structuring the update function to check for toggle input, manage the active state, handle navigation, and render the overlay with a background, header text showing the page name and hints, then draw the current page content into a designated rect. I'm realizing the layer commands get queued during the update phase before rendering happens.

The timing model is that update runs at a fixed 120Hz and clears all layer command queues at the start of each update cycle, so queuing UI draws during update works fine—they accumulate until the render phase. Even with multiple updates per frame during fixed timestep catchup, there's no duplication since queues reset each update. I'm wondering if draw-phase queues for the game world also clear at update-start, or if there's a different mechanism there. So render_uncapped is true by default in the config, but the demo doesn't enable it, which keeps things safe. The real ordering concern is that update() runs before draw(), so UI commands queue first on their layers, then world commands queue on theirs, and emoji_render processes everything at the end of draw in layer order rather than queue time. The gallery's overlay gets queued during update while the demo's background and world elements queue during draw, but the composite order follows the layer hierarchy, not when things were queued. Now I'm looking at how ui/init.lua sets up the module...

Loading all the UI submodules in order, then initializing ui_typed_text and the ui_begin function. The juice module needs sfx and sounds loaded first, which happens before UI gets required in the main emoji/init.lua, but since juice only calls sfx at runtime, the require order for those calls doesn't actually matter—the sounds table gets indexed when the function runs. Still keeping the order sensible though. The state.lua file is copied directly from snkrx and uses mouse_position, which works fine standalone. For the gallery's page wrapping, I'm using modulo arithmetic to cycle through pages.

Now I need to handle the tooltip that appears when hovering over a card, drawing it at a fixed position. I also need to wire up the input handling for the gallery toggle with F4, plus the previous and next bindings on the bracket keys, then write out the gallery and init modules.

Now I'm connecting all the pieces together—wiring up the emoji module to require the UI system, setting up sound effects through the UI layer, and then configuring the main file with the layer stack, key bindings, UI initialization, gallery updates, click detection, and hint text positioning. After that I'll run syntax checks and make sure everything syncs with the documentation.

I need to update the emoji/init.lua docblock to include ui in the module list, and I'm verifying that the require path works correctly — since Lua's standard package.path includes both '?.lua' and '?/init.lua' patterns, requiring 'emoji.ui' will properly resolve to emoji/ui/init.lua, similar to how snkrx handles its module structure.

For the main.lua changes, I'm setting up the layer stack, adding F4 + bracket binds, and updating the main loop to call ui_begin and ui_gallery_update with a click guard. For the hint text, I'm deciding between using the ui_text widget or drawing directly to the ui_content_layer — since the hint is static and commands queued during draw() render properly at the end, I'll keep it simple and use layer_text directly on ui_content_layer in the draw function.

I need to update the header docblock in main.lua to document the F4 and bracket key inputs alongside the existing controls, then run syntax checks on the modified files and verify that gallery.lua can properly access the global width and height variables that main sets up beforehand.

Now I'm checking the module load order and runtime dependencies — emoji.lua requires its submodules first before loading images, but since gallery.lua only references those images inside functions at runtime rather than at require time, there's no ordering issue. Similarly, widgets.lua precomputes color mixing at load time which is fine since the palette is already required, paint.lua's tier() function reads UI layer globals that get created later in main, and the UI field and slider components use standard fonts and simple geometry that don't have any dependency problems.

The real issue I'm spotting is with the slider track visibility — it's drawn as black on the charcoal background in the gallery, and even with a black outline it becomes nearly invisible. The in-world HP bar works because it's black on a light arena background, but the gallery needs a different approach. I could either make the track gray by default for dark backgrounds, or better yet, have the gallery explicitly draw its form sections on cream-colored panels like actual UI screens, which would solve the contrast problem cleanly.

For now I'm settling on keeping the widget defaults faithful to the in-world look (black track), and accepting that the gallery's bar will read as a dark slot defined by its outline and fill — the outline creates enough visual separation against the charcoal that it should work. I'll test it and adjust if needed.

Moving on to the checkbox implementation — it passes a fake rect for area scaling, which is fine since the area is only used for hit detection. The health bar also draws the value text directly inside the bar itself.

There's a text overflow issue though: the default bar height of 10 pixels is too tight for the 11-pixel font, causing the text to stick out by a pixel on top and bottom. I'm bumping the default height up to 12 pixels to give the text proper breathing room.

The gallery page has another problem — the demo hint text at the bottom overlaps with the gallery hint, and since the demo hint sits on a higher compositing layer, it shows up over the gallery background creating a visual mess. I need to add a guard that hides the demo hint whenever the gallery is active.

Also noting that the demo scene cursor draws over the gallery, which is intentional since it should stay on top. For mouse interactions on gallery widgets, the code checks for mouse button presses...

The button numbering is correct — button 1 maps to the left mouse button. The process order looks good too: UI begins at the top of each update, gallery widgets process before camera and entity logic, and the demo hint guard via the gallery active flag handles the overlap issue cleanly.

I've got three small fixes to make: the header input list, the HUD bar height at 12 pixels, and adding that demo hint guard. After that I'll do a syntax check across everything.

I've identified three small fixes needed: the hud_bar default height is too small for the font, the demo hint needs to hide when the gallery opens, and the header keybind list needs adjustment. I'll implement these now.

Checking the syntax across the codebase — the stencil mask function in paint.lua is valid, and the ui_slider widget correctly references the active state check from state.lua.

The gallery layout looks good with the 170px field width and 16x16 icon buttons, the tooltip math.clamp usage is fine, and the checkbox hover sound matches the sfx signature. The slider row height calculation works correctly with the track centered in the hit area, and the ui_label padding adds up to the expected 24px chip height. One thing to verify: the color_new function needs to properly handle the alpha channel when packing the cooldown shade color.

The ui_paint_stencil operations are correctly applied only to the panel layer while bar value text stays on the content layer unclipped, and the gallery title text auto-sizes its rect based on text width. The main edge case to watch is the update order — when the gallery is toggled closed the same frame as a click, the ui_state might not be properly inert yet.

For the gallery page 2 bar with health text, the 11px font fits fine in the 12px bar height, and the cursor correctly renders as a pointer when over the gallery. Now I need to update the CLAUDE.md file to document the UI section, add a file map, and tick off the roadmap — specifically marking the UI kit core pass as complete since we've finished the architecture and core implementation ahead of the original schedule.

I'll add a dedicated UI toolkit section that explains the calling convention, the chrome/host contract, and important gotchas like how fullscreen fills work on outlined layers and that UI updates happen during the update phase without a separate render call. Then I'll wrap up with test instructions.

Everything checks out. Now I'm syncing the CLAUDE.md project file with updates to the UI toolkit section, file map, and roadmap.

There's a nil error in the UI rendering when hovering over a button—specifically, `hfill` is becoming nil even though the hover state is active. I need to trace through the fill resolution logic to understand when `hfill` gets set and why it might be undefined in this scenario.

Looking at the fill assignment, when `opts.color` is provided, both `fill` and `hfill` get set. But for the ghost variant without an explicit color, neither gets assigned a value, so when the button is hovered and tries to use `hfill`, it crashes. The fix is to give the ghost variant a hover fill color—I'll use white to match the original behavior where ghost buttons invert to white on hover, which works because the text is outlined in black and rendered on a different layer.

Updating the ghost case...

The file E:\a327ex\emoji-template\emoji\ui\widgets.lua has been updated successfully. (file state is current in your context — no need to Read it back)

OK

I found the issue—ghost was the only widget missing a fallback in its nil-fill shape resolution, while icon_button, slot, bar, and card all properly chain through `or` operators to concrete tokens. Now I'm documenting the fix and adding a test to prevent regression.

Looking at the gallery page, I'm seeing that FatPixelFont is rendering way too large—the section headers like "UI GALLERY", "BUTTONS", and "FORM CONTROLS" are massive and overlapping with each other and the content below them, like the "PATTERN" label sitting right on top of the slider.

The core issue is that fonts.big has a reported height of 8 pixels but renders much taller in practice, which breaks the layout. The fix is to swap FatPixelFont out for fonts.main (LanaPixel at 11px) across the toolkit—using it for section headings in uppercase white, sublabels in muted color, and field labels. FatPixelFont should stay available but only for rare, intentional use cases rather than as the default for headers.

For the keycap specifically, fonts.main won't fit in the current 9px pill since LanaPixel 11 overflows, so I'll enlarge the keycap to 11x11 pixels and use fonts.main there, which keeps the proportion reasonable on a 28px slot. The card footer and chip labels like 'ROUND 2' also need to switch from fonts.big to fonts.main, adjusting the footer height calculation accordingly.

For the gallery header, I'm using fonts.mid for the "UI GALLERY" title to establish hierarchy (it renders at 16px, which works well for a screen title), fonts.main for the page indicator, and fonts.main uppercase for headings with a rule. The spacing issue in the screenshot comes from fonts.big rendering much taller than its true height, so switching to fonts.main should eliminate the overlap.

I'm also auditing other uses of fonts.big throughout the UI—the 'ROUND 2' chip, ui_slot cooldown text, ui_field labels, ui_heading, ui_sublabel, card footer, and slot keycap all need to shift to fonts.main for consistency, while FatPixelFont stays registered as fonts.big for rare cases. With the title positioned at y=8 in mid and content starting at y=24, the spacing should work cleanly now.

The page indicator on the right uses fonts.main as well. I'm making targeted font swaps across core.lua and widgets.lua—ui_heading and ui_sublabel both shift from fonts.big to fonts.main, and the slot keycap pill gets resized to 11x11 with the main font to fit the letter properly.

Continuing through widgets.lua: ui_field label switches to fonts.main, and the card footer adjusts its height calculation and font. In gallery.lua, the title moves to fonts.mid, the page indicator and its rect height use fonts.main, and the 'ROUND 2' chip font updates as well. The gallery title already uses auto rect positioning, so I just need to apply these font and dimension changes across the files.

I need to update the CLAUDE.md documentation with the font guidance correction and add a note about the FatPixelFont gotcha—it renders about three times larger than its registered height, which is a mistake other instances have made too. This warrants both a project documentation update and a cross-session memory entry so we don't repeat this issue.

I'm syncing the docs and pinning this as a cross-session memory to prevent this repeated mistake.

I'm wrapping up and need to summarize the diff and test instructions. Looking at the screenshot, I'm noticing some odd rendering issues with the button labels—they're showing garbled text like 'cf1crs' and 'c sab ec' where 'options' and 'disabled' should appear, which is definitely something to flag. The real issue is white text on light fills—the black outline layer creates a silhouette that bleeds into the thin glyph interiors, making them look broken. 'play' and 'delete' read fine on colored backgrounds (blue and red), but 'options' and the disabled text on cream and gray fills are unreadable. This is the same outline shader from aimer, but the light background makes the contrast problem much worse than it was in that context.

I shouldn't chase this too hard based on a potentially compressed screenshot—the user only flagged the FatPixel size issue. If the labels still look garbled after removing FatPixel (which will shift the whole layout anyway), they'll mention it. I'll note in the summary that if white Lana on light fills still reads poorly, we can switch to a darker label color instead.

The user's asking whether the visual design was intentional or if I planned to refine it later. I need to be honest about what happened — I ported the snkrx architecture and applied a baseline Aimer language style, but the result doesn't actually match what Aimer's UI looks like. Looking at the actual Aimer chips with their cream-colored rounded rectangles, natural-colored icons, and white text, I can see the gap between what I built and what the reference design shows.

What I actually did was invent most of the skin from first principles rather than carefully porting Aimer's pixel decisions. The button variants, checkboxes, sliders, list rows, and cards — none of those exist in the original; I created them "in the language" but without studying the reference closely enough. Aimer's UI always sits as chips and panels over a game scene with specific placements and proportions, whereas my gallery just has widgets floating loose on a flat charcoal background. Looking at the specific visual problems in the screenshot — the buttons are cramped and dense with heavy outlines, the white-on-cream contrast is too low, the slider track disappears against the charcoal, the hairline rules create stark white lines, and everything feels tightly spaced without breathing room.

The honest answer is I was aiming for a functional baseline that would be iterated on later with his feedback, and I did note in the roadmap that a style pass was planned. But I should own that the gap between what I made and Aimer's actual look isn't just about waiting for that next pass — parts of my invented widget skins, especially the buttons, don't match Aimer's quality because Aimer doesn't actually have buttons except for the shop's draw_shop_button, which I never studied closely. I ported the chip element faithfully since that's the one piece I read carefully, but I missed the mark on everything else.

The real miss is that Aimer's shop UI code already contains a full kit of drawing functions for buttons, tiles, tooltips, badges, and locked overlays that I should have consulted instead of inventing from principle. For widgets where Aimer has no direct equivalent, that's fair — but for the ones it does have, I should have sourced their actual pixel decisions rather than guessing. I need to answer his question directly—whether this was intentional or a style pass I planned for later—then lay out the fidelity proposal and let him decide if that's the direction to take.

Now I'm diving into Emoji Aimer's shop-kit and HUD drawing code to extract the pixel-level design decisions and apply them to reskin the toolkit widgets. I'm starting by reviewing the core drawing functions like the HUD chip, score panel, and multiplier panel to understand the visual styling approach.

Looking at the full scope of functions I need to examine—from the buff shield and inventory slots through the shop interface with buttons, tiles, tooltips, badges, and hover effects—I'm prioritizing which ones map directly to toolkit widgets: the shop button becomes ui_button, the item tile becomes ui_slot or ui_card, the tooltip system becomes ui_tooltip, the count badge becomes a badge idiom, and the owned slot styling follows from there. Now I'll refactor the skin decisions in the gallery widgets and primitives.

Looking at the button design specs — the fill transitions to white on hover rather than a lightened shade, while the label stays white throughout. The button has a cream base with green primary, disabled state uses a dark fill, and maintains consistent styling with 4px radius and 18px height. There's a scale transform applied only to the fill layer during hover, keeping the text unaffected. The hover interaction includes a subtle shake effect with ±2px movement and slight rotation applied per-element.

The grid layout uses 28×28 slots with 16px icons and 6-8px gaps between tiles. Above the grid sits a tier strip — a rounded rectangle divided into segments with 1px dividers, where the active tier shows as a yellow inset pill and hovering reveals a white pill. There's also a locked overlay using translucent charcoal with a lock icon for unavailable slots. Next I need to examine the tile structure, tooltip behavior, badges, and how the shop kit layout ties together.

The tile is the main component here. I'm thinking through the pixel dimensions—probably around 48-52px for grid tiles—with a rounded frame at radius 6. The fill changes based on state: white on hover, dark foreground for unaffordable items, and red for errors. There's a colored banner strip at the bottom (14px tall, yellow when affordable, gray otherwise) with rounded bottom corners and squared tops using filler rectangles, plus a 22px emoji near the top and white label text.

On hover, the frame turns white and gets a subtle wobble effect with a spring pulse animation. The tooltip has 6px padding, 12px line height, 16px header height, minimum width of 130px, and radius 6, with the coin icon at 9px and word-wrapped descriptions at 130px width.

I need to pull together the tile and tooltip constants, then write the drawing functions for tooltips, count badges, owned slots, tier headers, and the tier strip with its segments and yellow pill. I'm also tracking the hover state with lerp and spring pulse values, and I need to check how the shop UI kit layout works—whether it uses background panels or raw charcoal—plus integrate the buffs and HUD inventory drawing.

I'm pulling together the core visual principles from the Aimer design system: the primary fill color is a light cream tone used consistently across interactive elements like buttons and tiles, with darker variants for empty states. On hover, that fill shifts to pure white, and there's a subtle wobble animation that kicks in.

The text rendering is key — glyphs stay pixel-perfect by being drawn outside the scale transform with floored coordinates, so only the fill animates while typography remains static and sharp. Buttons are 70×18 with a 4-pixel radius, using green as the primary accent color (not blue like I initially thought), with white text centered and positioned carefully to maintain pixel alignment. The cursor also pulses sympathetically when hovering, and there's a gentle spring animation on hover-enter that's much more restrained than what I had before.

The UI also uses a banner idiom with colored status bands at the bottom of cards and tiles — yellow, gray, or red depending on state — with the label positioned inside the band and rounded corners handled via filler rectangles. Tooltips follow a similar pattern with a colored header band containing the item name and price chip, wrapped text in the body, and smart positioning that flips when it would overflow the viewport. Slots are small 28×28 squares with a 16-pixel centered icon (deliberately smaller than the slot itself), and a blue badge in the top-left showing the count. The segmented strip uses a single rounded container with the active segment filling in green, dividers separating each option, and a white hover state.

For spacing and polish, gaps between elements are 6–8 pixels, error states trigger a decaying horizontal shake animation, and the draw order separates fill rendering on the panel layer from text on the content layer. Now I'm mapping this to my toolkit — I need to add hover-wobble machinery to juice.lua with per-element shake tracking, a lerped hover amount that responds smoothly, and a spring-based pull on hover-enter, replacing my current hover implementation.

Extending the juice API... + oy, rot, s, s) when drawing widgets, with text rendered at absolute pixel-snapped positions like buttons and slots. For hover entry, I'm using a pull of 0.08 from Aimer, but buttons on click should pulse the spring by 0.2 instead. On the cursor side, I don't have flash_hover in my port, just pulse, so I'll wire ui_juice_hover to call the cursor's pulse method with a small force value. Now I'm rewriting the widgets.lua file to handle skins, starting with the button base.

For buttons, I'm supporting fg, primary green, danger red, and ghost variants with white hover fill across all of them. Disabled state uses dark foreground fill with white labels. The default height is 18 with a 4-pixel radius and padding of 8 horizontally and 3.5 vertically to accommodate the 11-point font. Labels stay white and pixel-snapped outside the scale push, while the fill gets the wobble transform applied. For slots, I'm using the same 4-pixel radius with foreground fill that turns white on hover, and empty slots show dark fill instead of just an outline. Icons scale to about 57% of the slot size, and selected state follows Aimer's approach.

For the remaining controls, I'm applying green to selected checkboxes and slots to match the new accent color, keeping off-state as dark foreground without gray tinting. Keycaps get blue fill to align with the meta/level/info semantic, and sliders use dark foreground for the track with green fill to stay consistent with the accent system.

For list rows, I'm using white fill on hover across both cream and charcoal backgrounds, with the selected state showing a green stripe plus white fill — though I need to be careful with text contrast when white rows sit on white panels.

Now for cards, I'm restructuring them to match the Aimer tile pattern: rounded corners, a colored banner band at the bottom (defaulting to yellow) with the title inside it, an icon near the top, and optional description lines between the icon and banner for taller cards. The card frame itself uses the foreground color with white on hover.

For fields, the arrow buttons are now icon buttons with the foreground fill and white on hover. The bar component keeps its black track for consistency. I'm also adding a tabs component using the segmented strip pattern—it's such a characteristic Aimer element with active green, white on hover, and proper corner handling for the first and last segments.

The tooltip is getting a complete redesign: white panel with a colored header band, the title on the left with an optional value chip on the right, wrapped body text with 12px line height and 6px padding, and a minimum width of 130.

I need to add a positioning helper for tooltips to handle placement relative to elements and flipping when needed, plus port the text wrapping utility into the primitives. For the gallery, I'm updating the demo pages to showcase the new tabs strip, button rows, tile-style cards with banners, and tooltips positioned next to hovered elements. The charcoal background for page content mirrors the shop aesthetic. The paint.lua file should be fine as-is since widgets already use absolute positioning.

For text rendering, I'm rethinking how transforms apply across different components — buttons and strip labels should stay static while the fill wobbles, but slots and cards need the full transform applied to both icon and content layers so everything moves together. The keycap on slots also goes inside the transform. I'm also updating the accent color from green to the primary fill color.

Now I'm working through the color scheme updates: the primary fill becomes green, hover states turn white across the board, and I'm removing the color mixing precomputes since aimer just uses plain white for hover. Selected states — cards, list stripes, and slots — all get the green accent. I need to update the documentation to reflect that the accent is now green, with yellow for money/attention and blue for info badges, and fix the primitives header comment that still says blue accent. The gallery cards page should use banner cards, and I'm refining the tooltip signature to include position, title, optional value and icon, and description strings.

Rewriting the tooltip with a header band containing the title and value chip, plus body lines below. I'm also porting text wrapping as a utility function and need to update several files: adding shake and hover transforms to the core, rewriting all the widget skins, implementing the new tooltip and text wrapping, fixing the panel radius, and reworking the gallery pages.

Starting with the juice.lua changes...

I've got the design reference and found several key corrections: hover fills turn white not lightened, the accent is green not blue, hover includes a wobble effect with spring and cursor pulses, button text is pixel-snapped outside the scale push, and various other component details. Now I'll rewrite the skins based on these decisions, starting with the animation machinery.

I need to verify that shake_new, shake_get_effects, and shake_update functions exist in the Anchor3 framework's shake.lua file, since my earlier search only turned up shake_trauma and shake_handcam at lines 66 and 153.

169:function shake_get_effects(s)
232:function shake_update(s, dt)

Now I'm rewriting the widgets based on Aimer's actual pixel decisions.

I'm realizing the wobble effect includes rotation, but I'm not passing that through to the paint push function—I'm only sending position and scale while discarding the rotation value. I need to update the paint push signature to accept a rotation parameter and then fix all the call sites to pass it through.

There's also a redundant condition in the slot empty branch that I can simplify. After fixing the paint signature across the widgets, I'll rewrite the tooltip using the Aimer design with text wrapping and positioning, update the gallery, then apply the paint push fix.

I'm fixing the paint transform to carry the wobble rotation and cleaning up the slot's empty branch.

The sed command worked as expected. Now I need to refactor the ui_tooltip function in primitives.lua to match the Aimer design, add the ui_wrap_text and ui_tooltip_position functions, and fix the header comment to use accent green. After that, I'll tackle the gallery rework, then run syntax checks and update the CLAUDE.md documentation.

I'm planning the gallery updates: reworking page 3 to use banner tiles with positioned tooltips showing coin values, adding a tabs demo to page 1, and including an empty slots example on page 2. I'll need to update the component calls to use the new banner signature instead of the old footer/title/lines pattern, adjust the tooltip calls for their new interface, and add a ui_tabs demo to showcase that component.

I'm reworking the gallery to test the new skins, including tabs strip, banner tiles, and anchored tooltip.

Page 2's keycap slot is now blue and the disabled cloud slot renders properly with its icon. The empty slot displays with a dark flat style, which is a good example of the empty state pattern. On page 1, I'm concerned the controls section with tabs might exceed the available height—let me check the math on the stack layout to see if everything fits within the 480x270 bounds.

After tallying up the heading heights, spacing, and content rows, the list section overflows by about 36 pixels. I need to reflow this—either move the list to page 2 or split page 1 into two columns. The simplest approach is to place the list as a right-hand column alongside the form controls on the left.

Restructuring page 1 with tabs full-width at the top, then creating two stacks below: the left column holds buttons and form controls, while the right column contains the list with its header and rows.

Now I'm checking the vertical spacing — the left column fits within the available height with buttons, form fields, checkboxes, slider, and text input all stacking properly. The right column's list header and rows also fit without overflow. The main concern is whether the five buttons in the row will stay within the 210-pixel column width or spill into the right section.

Looking at the button widths with padding, they total around 260 pixels, which exceeds the 210-pixel constraint. I'll split them across two rows instead — play, options, and delete on the first row, then ghost and disabled below. The field and slider dimensions work fine within the column width, so I'll update the page layout with this adjustment.

Page 1 is now overflowing past 270px with the tabs section, so I'm reflowing it into two columns.

Checking the layout heights across pages—page 3 fits within its bounds with the content, headings, rows, and gaps all aligning properly, and page 2's HUD elements including the heading, chips, bars, buttons, and slots all stack within the available space. Now looking at the chips component on page 2 and its UI label.

The chip row heights work out to 24 pixels with the padding, so taking that height is fine. For the list row hover and selected states, I'm using a white fill with white text, which relies on the outline to keep it readable—this matches the aimer treatment for labels on white backgrounds. Checking the tabs component, the hover state applies the juice hover effect which triggers sound and cursor pulse but doesn't actually transform the visual appearance, so there's no wobble in the draw—this is consistent with aimer's approach of just highlighting the pill without any transform.

Now I need to syntax check all the edited files and update the documentation—the project memory currently says states use fill shifts with blue accent, but that's outdated now with the green accent and white hover states. I should update the project template and rewrite the UI section in the main documentation to reflect the wobble, banner idiom, and tabs being added to the element set.

Now I'm wrapping up with a final summary and test instructions, making sure to call out the visual changes for each widget so you can easily spot the differences compared to Aimer.

The user is pointing out that the gallery's dark charcoal background is affecting how the UI elements read visually — the shop interface normally sits over Aimer's actual game context with the sky gradient and board in the middle, but the gallery's flat charcoal overlay changes the perception of elements like the cream chips. I'm trying to recall what Aimer's shop background actually is and how the shop UI gets rendered.

Looking at the layout more carefully: the tile grid spans the middle area over the sky-gradient board, and the side columns sit on the light cream-tinted walls. So the cream chips are normally read against light backgrounds (the sky gradient and cream walls), where the black outlines provide separation. On my flat charcoal gallery background, those same cream chips create much higher contrast and read as dark blobs, completely changing the mood and visual hierarchy.

The user's right — the eye-test isn't fair because the backdrop doesn't match the real game context. I could fix this a few ways: mimic the game's actual background (charcoal page with a sky-gradient board in the middle and walls on the sides), let the running demo scene show through instead of the opaque charcoal fill, or add a background toggle key so I can A/B test between charcoal, the sky-board layout, and the live scene. Since the whole point is eye-testing, a cycle key seems like the best approach.

I'll keep it simple: three modes — 'board' (the sky-gradient board with charcoal surround, matching Aimer's shop), 'dark' (flat charcoal), and 'live' (transparent, showing the scene behind). The 'b' key cycles through them, defaulting to 'board'. I'll draw the sky board the same way the demo does: charcoal fill across the screen, then a sky-gradient rectangle in the center area where the widgets sit, with cream-tinted wall columns on the sides. I'm settling on a simpler approach: charcoal background with an inset sky-gradient board (12px margin) where widgets sit mostly on the sky, plus two other modes—a flat charcoal 'dark' variant and a transparent 'live' mode that shows the demo underneath. I'll cycle through these with the B key and set 'board' as the default, then wire up the background binding in the main config so the gallery can read and respond to it.

The hint line updates to show the new control: "[ / ] page | b: bg | f4 close", and the white outlined "UI GALLERY" header will read clearly against the sky background. His observation about the charcoal clashing with Aimer's light-background aesthetic is spot-on—this toggle lets him test the widgets in their proper visual context.

I'm noticing some design tradeoffs in live mode—the demo hint text disappears when the gallery is active, which is intentional, while the scene continues animating behind it to show the live updates. The gallery widgets overlaying the moving background might be harder to read, but that visual complexity actually helps with testing. There's also a contrast issue in board mode where the dark foreground text on the light sky background needs adjustment.

The light gray text with black outline should provide enough contrast to read clearly. Now I need to do a syntax check on both gallery.lua and main.lua files, then finalize the test instructions.

Looking at the screenshot, the selected row has a white fill with a black outline around it—that outline is coming from the panel layer's silhouette effect. The user wants to remove that boxed appearance so the selected row fills completely without the visible border and spacing gaps between rows.

The issue is the 6px gap between rows in the stack—it isolates the white selected row, giving it its own outline. To fix this, I could either remove the gap and place the rows on a background panel so interior fills don't outline, or modify the row component itself to handle the selected state differently. The widget itself doesn't need to change — the gallery's layout is the issue. I'll fix it by wrapping the list in a cream panel and removing gaps between rows so they sit flush, making the selected row's white fill feel like an interior highlight rather than an isolated box. Setting up the panel dimensions and positioning rows contiguously inside it.

The docstring for ui_list_row already specified the correct behavior—rows should sit over a ui_panel with interior fills and no extra outlines—so the widget contract was sound; the gallery just wasn't demonstrating it properly. Now that it's fixed, the gallery shows the intended composition as designed.

The user is saying the list layout works better but needs more breathing room between the rows by default—they're looking at the current 13px spacing with 11px text and finding it too cramped.

I'm weighing whether "spacing between elements" means just the list rows themselves, or if it's pointing at the broader toolkit defaults like the gap scales (ui_sp.s2 and s3) that affect chips, buttons, and other components throughout the gallery. The phrase "by default" suggests they want me to adjust the toolkit's baseline spacing rather than just tweak this one gallery. I could bump the default row height to 15–16px with some cell padding, and possibly increase the chaining and stack gaps in the spacing scale, but I'm uncertain about the exact scope—might be worth asking for clarification rather than guessing. Now I'm working through the exact pixel calculations for the right column layout with the new spacing values. With the bumped stack gap and row heights, I'm checking whether the tabs section, buttons, form inputs, and slider all fit within the page bounds—looks like it comes in tight around 210 pixels for the slider baseline, which should work. The hint line at 256 is the actual visual boundary, so the field ending at 248 leaves enough clearance. Left column fits at 248. For page 2, I'm checking the layout with the spacing adjustments: chips section flows from 49 to 81, bars section from 102 to 142, and slots from 189 to 217 — all within bounds.

Page 3 also fits: the first row spans 49 to 105, then there's a gap before the second heading at 128, with the second row extending to 210. The ui_ret spacing change from 4 to 6 adds more horizontal breathing room across buttons, chips, slots, and cards. Buttons row comes to about 158 pixels, slots to 164, and the card row now has a 12-pixel gap between items — everything checks out.

I'm settling on the spacing scale as s1=2, s2=6, s3=8, s4=12, s5=16, and bumping the gallery list row height from 13 to 16 pixels. The s4 gap on page 3 stays at 12, which works fine.

Looking at the screenshot, the green selection stripe on the left is sitting too close to the text—only about 2 pixels of space between them, which makes them visually touch when you account for the black outline on the glyphs. I should increase the padding between the stripe and text, either by bumping up the cell's left padding from 4 to 8 pixels, or by adjusting the text inset when a row is selected.

The fix is straightforward: set the cell's starting x position to `r.x + 8` instead of `r.x + 4`, and adjust the flex width calculation from `r.w - 8 - fixed` to `r.w - 12 - fixed` to account for the extra left padding. This gives us 8 pixels on the left and 4 on the right, creating a 6-pixel gap between the stripe and the text. It's a simple adjustment to apply.

The user's checking if we can wrap up the UI work here—we've completed the core kit pass, fidelity improvements, and spacing adjustments. There's still a backlog of smaller widgets to build out, plus the F3 sound tuner and some Persona-style exploration that ties into the effect system work coming later.

Looking at what the effect-system port actually needs: the paint hook is already in place, and for the inspector tools we'd need swatch_row (which the color picker relies on), but that's small enough to build during the effect session itself when we hit it. The F3 tuner has all its dependencies ready. So yeah, the core UI is solid enough to move forward—the remaining pieces can slot in as their consumers come up.

I should update the roadmap to mark the UI kit work as done-ish (core + fidelity pass + eye-tested), move the long-tail items to later, and sync the memory file. Then I'll confirm the next step is the effect-system port.

[sealed content withheld: memory]

I'm trying to figure out what "Go ahead" means here. Last time they explicitly said not to post a brief, but this time it's just "Go ahead" without that clarification. My previous message said I'd open with the design brief, so I'm uncertain whether they want me to skip it or proceed with posting it first.

I need to research the effect system port: the core effect files from snkrx, how the shader setup works, and whether the custom draw shader affects the outline and shadow post-process passes that use their own specific shaders versus the default engine shader that handles all the queued draws.

For the emoji palette adapter, I'm mapping out the token names (white, black, gray, bg_color, fg, fg_dark, yellow, star_yellow, orange, blue, green, red, purple, brown, pink, bowstring, bronze, silver, medal_gold, sky_top, sky_bottom, wall_color — 22 tokens total) and need to ensure the shader's u_palette array size matches this count, then figure out the effect_setup call path and whether it points to `assets/draw_shader.frag` or a snkrx-specific path.

For paint.lua integration, I'm wiring the ui_spec_for logic to handle token-to-spec mapping, wrapping ui_fill and ui_content calls with effect_set/effect_clear brackets, and deciding on a default ui_color mode — probably 'solid' for the flat emoji aesthetic with effects as opt-in rather than the breathe effect that's core to snkrx's look.

I need to port snkrx's effect_lab as an F5 inspector using our toolkit and build out ui_swatch_row for testing. The dithering defaults to off, with halftone and manga-dot exploration happening during eye-testing. On the engine side, the aux-sampler patch is already in place, but draw_shader.frag needs the palette count parameter added.

Before diving into the brief, I should review snkrx's effect.lua (checking at least the header and spec API surface), palette.lua for the adapter shape, how draw_shader.frag binds through effect_setup, effect_lab.lua for the inspector port, and the ui_swatch_row widget implementation.

I also need to verify how draw_shader.frag receives the palette size—whether it's fed via u_palette[26] through shader_set_vec4_immediate or effect_write_palette—and trace where effect_set writes uniforms, particularly whether it queues layer-specific shader updates per layer and how shader uniforms persist across subsequent draws on the same layer.

The key integration challenge is that our pipeline renders many layers while the draw shader is global, so every layer receiving an effect_set needs proper clearing with a default passthrough state to preserve current visuals. I also need to check how glyph rendering flows through the draw shader in the snkrx template.

Looking at the Anchor3 fork from July 2026 — I'm trying to verify whether the per-glyph shape0 sub-rect patch for local text gradients made it into Anchor2 main by that point, since snkrx-template lists it as part of its patched executable. The patches were applied to the shared Anchor2 engine source in earlier sessions, so I should grep the anchor.c file to confirm the glyph shape0 sub-rect marker is present; if it's missing, text local gradients would degrade.

Now I'm diving into the palette.lua adapter to understand how it connects the pieces, then I'll check the effect_lab.lua structure and review the defaults and registries at the top of effect.lua.

2     palette.lua — locked color tokens + the effect-system palette adapter.
3   
4     This file is the SINGLE source of truth for what colors the project uses.
5     Three sections:
6   
7       1. NAMED COLOR TOKENS (atoms). 18 canonical tokens that form the
8          project's locked palette (9 chrome / grayscale ladder + 9 accents
9          roughly by hue), plus 8 legacy SNKRX tokens. Every drawn thing
10         should pull from these tokens; no inline RGB values in game code.
11  
12      2. THE EFFECT ADAPTER. `palette` (name → color object), the ordered
13         `palette_token_names` list, the `palette_token_index` (0-based)
14         map, and `palette_init()` — everything snkrx/effect.lua needs to
15         push the palette to the draw shader's u_palette[] uniform array
16         and to resolve a spec's `color_a` / `color_b` token NAME into the
17         integer index the shader expects.
18  
19    The four-axis effect system (snkrx/effect.lua + assets/draw_shader.frag)
20    is the project's rendering substrate — there is no separate "edition"
21    system anymore. A drawable carries a four-axis SPEC (pattern × color ×
22    dither × shape); the color axis names tokens from THIS file.
23  
24    USAGE
25      Tokens are global functions. Call them with () to get a color value:
26          layer_rectangle(layer, 0, 0, 100, 100, red())
27          layer_text(layer, msg, font, x, y, text())
28  
29      For the effect pipeline, pass the token NAME (a string) via a spec's
30      color_a / color_b:
... [148 more lines]

I'm seeing a key conflict in how the palette tokens work: snkrx defines its own color tokens like white, bg, and red, but the emoji palette already has those as global definitions. The emoji adapter just maps existing globals into the token tables without redefining them. There's also a mismatch where effect_set defaults to 'ink' and 'field' as fallback colors, but those are ricochet-specific names that don't exist in snkrx's token set.

For the emoji palette, I need to handle the resolve_color fallback carefully — when a color isn't found, it defaults to token 0, so I should order the emoji tokens with 'white' at position 0 to make that sensible. The effect.lua file references the global `time` variable which is fine, but its `spec_color` fallback uses `palette.text` which doesn't exist in emoji — I'll change that to `palette.white` or `palette.fg` instead. The emoji token list has 22 tokens defined, and while the shader array is sized for 26, I'll keep it at 26 to leave room for future additions.

For the breathe partner analog, I'm building a color relationship table that chains similar hues together — black through the grays to white on the brightness axis, then red through the full hue wheel back to red, with special tokens like bowstring and bronze mapping to their nearest neighbors. This table is cheap to maintain and the inspector uses it as a default for color_b.

Now I need to port the draw shader, copying it verbatim but updating the palette index comment to reflect emoji tokens instead of snkrx tokens.

But there's a critical integration issue: snkrx uses flash_spec for flash effects while our engine relies on the flash parameter in the draw call. If I copy snkrx's draw_shader.frag and it doesn't implement flash support, our hit-flash mechanic breaks entirely. I need to check whether the shader handles flash or if I need to add that support.

I'm checking whether snkrx's replacement draw shader supports the engine's native flash parameter that our juice depends on.

25://   vAddColor  Per-vertex additive RGB offset (engine 'flash' channel).
---

25://   vAddColor  Per-vertex additive RGB offset (engine 'flash' channel).
82:in vec3 vAddColor;
745:        vec3 col = texColor.rgb * vColor.rgb + vAddColor;
844:    vec3 col = vColor.rgb + vAddColor;

The draw shader's flash channel works through the additive color parameter — when I apply a white flash effect, it adds white to the texture output and saturates to pure white, which is exactly what I need. I've now got all the pieces for the design brief: a four-axis effect system port that involves directly translating the original effect code and shader implementation.

For the palette adapter, I'm appending helper functions to handle the emoji token mapping — organizing the 22 tokens in a specific order (chrome ladder, accents, extras, sky), setting up the palette initialization, and tuning the breathe partner function to work with the emoji's color space. Then in the boot sequence, I wire everything together by calling palette initialization and effect setup after loading modules and assets, which installs the shader and leaves all existing draws in passthrough mode so the current demo renders identically until effects are explicitly triggered.

Now I'm thinking through the effect state management — whether each layer needs a defensive baseline clear at frame start. The uniform state persists across frames per layer, and since the default is passthrough with brackets restoring that state via effect_clear, technically no per-frame baseline is needed. But snkrx does it defensively in ui_begin anyway, and it's cheap enough — just a few uniform writes per layer. I'll add that defensive baseline for the four UI layers in ui_begin to match snkrx's pattern, while keeping game-side bracket discipline documented rather than adding extra clears there.

For the paint.lua integration, I'm setting up the core widget functions: ui_spec_for resolves the effect spec with override priority, defaulting to 'flat' mode for emoji (no bracket, zero overhead) or 'mix' mode for the organic breathing effect with token-partner mixing. The widget drawing functions — ui_fill_rect, rrect, circle and the text/icon variants — will bracket with effect_set/effect_clear when the spec is non-nil, falling back to raw draws when it's nil for speed. This makes the spec option work on every widget immediately without needing special cases.

For ui_swatch_row, I'm building a grid of token color swatches with rounded corners and a green ring stroke for selection state — the ring avoids conflicts with white token swatches and uses the inset stroke capability we have in Anchor3.

Now for the F5 inspector: it's a canvas showing sample drawables (rect, rounded rect, circle, and an emoji image) that you can click to select, with an inspector panel below offering field cyclers for pattern/color/dither/shape, color swatches, and sliders for scale/speed/contrast and other parameters — the main loop wires the effect_lab_update and renders it on the overlay.

For the layer structure, I'm thinking the samples need to draw through the effect shaders on the overlay layer itself, with the background fill underneath. Since the overlay has no outline, the effect samples won't get any chrome applied, which is actually ideal for testing the pure effect without emoji styling getting in the way.

I need to wire up the F5 keybinding in main.lua to toggle the effect lab, add the update loop, and implement click suppression so scene interactions don't fire while the lab is open—I can reuse the same suppression logic that already handles the gallery being active. Also need to verify the layer shader functions are available for setting integers, floats, and textures, then update the docs with the new keybindings and effect section.

Flash is compatible with the draw shader since it uses the engine's flash channel, so I'll do one final API check before summarizing the findings.

222:function layer_shader_set_float(lyr, shader, name, value)
234:function layer_shader_set_int(lyr, shader, name, value)
238:function layer_shader_set_texture(lyr, shader, name, texture_id, unit)
14786:    lua_register(L, "get_draw_shader", l_get_draw_shader);
14792:    lua_register(L, "shader_set_vec4_immediate", l_shader_set_vec4_immediate);

All the necessary APIs are in place, so I'm ready to share the design brief and then iterate based on feedback.

I'm laying out the implementation plan for the effect-system port: copying and adapting the shader fragment file to the emoji template assets, migrating the effect module with updated token defaults from ink/field to white/fg, adding a palette adapter, and wiring it into the emoji initialization.

Now I need to review the full effect.lua file—specifically the registry and spec documentation sections I haven't examined yet, plus the wrapper functions at the end—to make sure I port everything correctly.

4     THE 30-SECOND MENTAL MODEL
5       Every draw routes through assets/draw_shader.frag. The shader takes
6       four orthogonal selectors and composes them as:
7   
8           f = pattern(world_pos, time)          -- spatial structure + animation
9                                                 -- (or, for an image, its luminance)
10          f = shape(f, pixel_pos)               -- re-express as a grid of shapes
11          f = dither(f, pixel_pos)              -- quantize to discrete levels
12          rgb = color(base_rgb, f, palette)     -- map f → palette token(s)
13  
14      Pattern owns "what the field looks like" AND "whether it moves over time."
15      Shape optionally re-expresses the field as a grid of circles / geometric
16      shapes / tiled icons. Color is a pure recipe that picks (or mixes) palette
17      tokens by f. Dither inserts the pixel-art stipple. All four are independent.

I'm working through the initialization sequence: setting up the emoji module to require the effect system after the palette loads, calling the palette and effect setup functions at the end after assets are ready, then waking up the paint system, establishing the UI baseline clears, building the widget swatch row, setting up the effect lab, and finally wiring everything together in main.

Working through the UI initialization sequence: clearing the baseline effect across four UI layers in init.lua, then handling the swatch row widget and effect lab components. I need to guard against nil references for those layer globals since they're only defined after emoji_layers loads, and there's an incomplete thought about the effect clearing logic that I should finish once I see more context.

I'm settling on using the direct layer call for the stroke rings in the UI swatch row since it's a dev-tool widget and the base tier is appropriate here. Now I'm moving into the effect lab design, setting up an F5 effect inspector with an active flag and sample data structure.

The layout has an inspector panel on the left (~150px) and a canvas area on the right, with four sample effects to showcase: an organic-patterned rounded rectangle with a breathing color mix, a halftone-style solid rectangle with circle dithering, a plasma-patterned circle with reduced scale, and an image sample using luminance mode with dithering and recoloring applied.

For the effect lab update loop, I'm toggling the panel on input, drawing the background overlay, rendering each sample through the effect system, and marking the selected sample with corner brackets. Click detection will switch the selection when the user clicks on a different sample.

Now I'm building the inspector panel on the left side with a stack layout containing the effect lab heading, pattern cycling controls, color and dither fields, shape selection, and color swatch rows for picking color A and B. The swatches fit about 11 per row at the given dimensions, so I'm laying them out across two rows of 23 pixels each.

For the sliders, I need to map several parameters: pattern scale from 0 to 1 representing a range of 0.05 to 1.5, speed from 0 to 3, contrast from 0 to 3, value from 0 to 2, a per-pattern parameter from 0 to 1, and shape size from 2 to 48 pixels. Each slider displays its current value. The panel is getting too tall though — the heading, fields, swatches, and all six sliders add up to over 330 pixels when I only have 270 available. I'm trimming down to just four key sliders: scale, speed, contrast, and shape size, which brings the height down to a manageable 88 pixels.

Now I'm tightening the layout further by reducing gaps and row heights. With a heading at 16 pixels, four fields at 18 pixels each, two swatch blocks at 38 pixels each, and the four sliders at 14 pixels each, I can fit everything into about 220 pixels plus padding, leaving room within the 270-pixel constraint. I'm also considering whether to add tiny labels directly to the left of each slider for clarity.

For the slider implementation, I'm planning to render each slider row with a text label on the left (around 52 pixels wide) followed by the slider itself taking up the remaining space, keeping each row at 12 pixels tall. The values will display in the fields below using formatted names for patterns, colors, dither modes, and shapes. I need to map the slider ranges to the actual spec values—scale from 0 to 1 normalized to 0.02 to 1.0, speed from 0 to 3, contrast from 0 to 3, and shape size from 2 to 48 pixels.

For the nil defaults in spec fields, I'll initialize sample specs with explicit entries so the cycling functions work properly. I'm also adding a DUMP button that serializes the current spec as a Lua literal, printing it and copying to clipboard if available, which is useful for saving tested configurations.

Now I'm wiring everything into main.lua: binding the F5 toggle for the effect lab, calling effect_lab_update after the gallery update, and guarding clicks so the lab only responds when neither the gallery nor lab are active. The effect_lab module gets required from emoji/init.lua after the ui module since it depends on ui widgets, and it uses the global gw/gh dimensions that are already set up. There's a potential issue with samples being drawn on the same overlay layer as the gallery background.

To handle both panels being open at once, I'll add mutual exclusion: toggling the lab off closes the gallery and vice versa. For the selection marks, I'm drawing four corner L-brackets using small white rectangles at the corners of the selected sample's bounding box. I should also check how clipboard operations work by looking at the existing clipboard_set implementation.

Now checking the F5 effect lab for the clipboard binding related to the spec DUMP feature.

Now I'm wiring everything together: requiring the effect lab in the init file after the UI loads, making the gallery toggle close the lab, and setting up the main file with an F5 keybind, effect lab updates, click guards, and hint text. I also need to check the panel height constraints for the lab inspector—with a 262-pixel panel and elements stacked from y=10 with 2-pixel gaps, the heading calculation works out to position the next UI element around y=30.

Working through the vertical layout: the heading takes up space, then fields, grids for swatches, and sliders all need to fit within the panel bounds. The grid calculations show three rows of swatches at roughly 36 pixels each with gaps, followed by four slider rows at 14 pixels each, which pushes the total past the 262-pixel limit. I'm considering trimming the swatch size from 10 to 9 pixels to save space and recalculating whether everything fits within the panel constraints. The swatch size is too large, so I'm trimming it down to 9 pixels, which saves 6 pixels overall and fits the row within the panel bounds. I need to pass this size parameter to the grid height calculation and the swatch row functions. I'm also making sure the lab heading displays correctly and setting up the gallery toggle to close the lab when activated.

For the gallery toggle, I need to guard against the effect_lab global not being loaded yet—setting it to false when it's nil is safe, so I'll add that check to handle the initialization order properly.

I need to update the main.lua header with the input list for F5, then run syntax checks across everything. There's a keybind verification to confirm — the 'toggle_effect_lab' name in F5 matches what the lab expects in input_pressed. I should also check the field label widths in the UI, particularly how the main font handles the label positioning on the left side.

Looking at the dither field layout, the label 'DIT' takes up about 20px on the left, and the value area is 94px wide right-aligned. Longer dither names like 'line diag flip 8x8' run around 85px, which means there could be some visual overlap when the value starts at x+9 and the label ends around x+20. It's not ideal, but acceptable for a dev tool — I'll leave it as-is for now since users probably won't hit the longest names consistently. Time to run the syntax checks and make that header edit.

Checking the timing and lifecycle of a few key functions — `time` is properly synced in effect_set whether it's called during update or draw, so that's consistent. Now reviewing ui_begin's effect_clear to make sure it runs before emoji_layers are initialized.

The effect_draw_shader gets set up at require time when emoji loads, and ui_begin runs after that, so the dependencies are in the right order. The engine loads shader paths relative to the game directory, which matches how snkrx handles it.

In the lab, the fields draw before sample hit-testing, but the click guards keep them separate — panel widgets use ui_interact while the scene has its own click guard, and swatches within the panel prevent accidental sample deselection. Lab sliders share IDs across samples but pull their values from the spec each frame, so they stay stateless except for animation juice. The ui_field calls always have spec values set, so no nil issues there.

For the image sample with luminance mode, the shader uses the image's luminance as the field while the pattern only affects ripples through image_pattern_amount set to zero, creating a halftone effect by mixing the background color over the luminance data. The overlay layer draws from the lab's update function, and gallery and lab are now mutually exclusive toggles. The ui_token_name in paint.lua builds at require time from the palette table, which loads first, so that's fine. The spec_open allocations are minimal since ui_spec_for returns nil quickly in flat mode, and the DUMP button just uses ui_button. There's a potential issue with effect_clear setting pattern_kind to 2 while the default shader state at boot has uniforms at zero, so pattern_kind might start at zero instead — need to check what the shader does when pattern_kind is zero.

At boot before any effect initialization, all layers render with pattern_kind, color_kind, dither_kind, and shape_kind all at zero since GL defaults uniforms to zero, but value_mult being zero would multiply everything to black, which would break rendering. Since snkrx works fine, either the shader guards against this or effect_setup/clear initializes the state properly — I need to check whether snkrx calls effect_clear on boot.

I'm checking how the shader guards against GL uniforms defaulting to 0, which could black out draws on layers that never get a bracket if `u_value_mult` is zero.

867:    FragColor = vec4(col * ((u_value_mult > 0.0) ? u_value_mult : 1.0), vColor.a * alpha);

The shader has a guard that treats zero value_mult as 1, and the default state with color disabled, dither off, and no shape means the pattern never gets evaluated, so contrast doesn't matter either—the boot state is safely passthrough and the invisibility guarantee holds.

Now I need to sync the CLAUDE.md documentation with the effect section, keybindings, and roadmap, update the memory, and then provide a final report with test instructions.

The shader already has a guard for this case, and kind-0 states are passthrough, so it's boot-safe. Now I'll work on the doc sync.

Looking at the F5 lab screenshot, I'm identifying which elements to keep and remove: the organic breathe effect in the top-left stays, the halftone circle-grid in the top-right gets removed, and the plasma-ramp circle in the bottom-left is being retained.

Instead of the shape axis they want to remove, they're asking for decorative shape-field backgrounds inspired by anime and manga aesthetics — think outlined circles or diamonds drifting across a background in slightly darker tones, or the classic screentone/dot pattern where varying-sized circles add texture and noise to a flat image. These shapes would be arbitrary in form and size, with their distribution driven by either static patterns like gradients or dynamic ones like plasma, and they'd sit behind the image as standalone decorative underlays rather than as a fill expression. Yes, I see the distinction clearly now. The shape-axis is a halftone renderer where the shapes themselves become the fill, carrying its color information and replacing the surface. What you're describing is fundamentally different — a decorative layer where shapes are ornamental sprites with subtle color variations (tone-on-tone), positioned and sized by a pattern field that drives their parameters rather than masking coverage. So I should confirm this understanding, articulate the design difference precisely, and then sketch out the implementation approach — whether this is a new shader pass, a separate pattern axis, or an ornament system — along with the key design questions we'd need to resolve before building it.

On the shape-axis removal: stripping out the halftone-grid semantics (the coverage/fill-replacement logic) makes sense, but the shape SDF functions themselves — circle, square, diamond, ring, cross — are exactly what the new decoration system would reuse for drawing ornaments at grid cells with varying size. So we're not discarding the shape-mask gauge machinery; we're repurposing it from a fill-coverage tool into a shape-drawing tool for the deco layer.

For the decoration system itself, I'm thinking through concrete use cases: anime-style outlined rings scattered on a flat background with subtle color shifts and possible drift/rotation, manga screentone effects with dots of varying sizes and density that fade along a gradient or pulse with animation, and more generally arbitrary shapes like circles, rings, diamonds, crosses, or stars layered over the base image.

The core idea is a cell grid where each cell samples from a driving field—whether static like a linear or radial gradient, or dynamic like plasma—and uses those values to modulate the shape's parameters: size, rotation, offset, and color blending. Everything composites over the base fill.

This sits alongside the existing shape system but with inverted compositing logic. Instead of shapes being the surface itself (where the pattern drives the mask), these decorative shapes layer on top of whatever the fill already produces—solid color, gradient, whatever—and blend in using a shifted or secondary color. So it's really a new independent axis in the design system: a decoration or ornament layer that adds tonal variation and visual texture without replacing the underlying surface.

Now I'm thinking through how the decoration should be driven. The user mentioned it could follow static patterns like linear or circular gradients, or even dynamic ones like plasma. The key question is whether the deco layer uses the same pattern field as the base color, or if they should be independent. If the base is a flat color and the deco is sized by a gradient, or vice versa, we'd need to evaluate two different fields in the shader instead of just one. The key decision is whether to give the decoration pattern its own driver selection, reusing the pattern registry but with separate uniforms for scale and speed, or keep it tied to the background. I'm leaning toward the lighter approach—let the deco have its own driver choice while staying within the same pattern system, then present both options to him since this is fundamentally a design question. I should confirm I understand the use case, sketch out the tradeoff, and ask what matters most: independent control over dot behavior versus shader simplicity.

For the parameters themselves, I'm tracking: shape kind and size variation, rotation modes (fixed, random, or field-driven), spacing and jitter, color offsets or explicit token pairs, and animation drivers. The outline feature adds complexity—either a ring width parameter or new stroke variants for shapes like hollow squares and diamonds using signed distance functions. On compositing, I need to clarify what he means by "behind the background"—if the deco is part of the background itself (base color plus decorated shapes), that's different from deco behind a foreground image, but both are just draw order at the game level rather than shader concerns.

The actual design extends the spec with a deco block that includes the shape type, optional color token or shade multiplier for deriving color from the base, size in pixels with variation, and likely rotation and spacing parameters.

Defining the deco parameters... Dither should stay clean on the deco itself, applied to the base before compositing. Since we're removing the shape axis entirely, I can repurpose its shader uniforms and machinery—the effect_field sampling and mask gauges become the deco system with new compositing rules and additional controls like jitter, outline, shade-color, and size variation. This reframes the implementation as transforming the shape axis into a deco axis, reusing the same underlying code with different semantics.

For the driver, I'm leaning toward giving the deco its own independent pattern evaluation—calling the pattern functions with separate scale and speed parameters, which opens up possibilities like a background gradient with plasma-driven dots. That's roughly ten extra uniforms, and I'll default to using the same driver when the deco_driver isn't explicitly set.

I need to clarify a few things in my response: confirm that the core idea makes sense (decoration layer on top of a base surface rather than shapes replacing the surface), then nail down whether we're removing the shape axis entirely and what happens to sprite-based icons—though reusing them as decoration shapes could be really nice for an emoji-style tone-on-tone effect. For the design, I'm thinking deco replaces the shape axis rather than adding alongside it, uses the same gauge and cell machinery, and defaults to an auto-shaded version of the base color. I'll wrap up the design brief and lay out the key decisions we need to make moving forward.

I've got three design approaches approved: deco replacing the shape axis, own-driver-with-fallback, and screen-space anchoring v1. The user said to go ahead with my default preferences after I laid out the design in detail, which suggests they want me to move forward with implementation rather than write out a full brief first—though my previous message indicated I'd write the brief once they confirmed those three points. Now I'm ready to implement the shader and Lua changes. I need to first examine the existing shape implementation in the fragment shader to understand the current uniforms and masking logic, then replace the shape coverage semantics with decoration uniforms—mapping the original shape kinds (circle, square, diamond, hexagon, ring, cross, triangle, sprite) to simplified decoration kinds where ring becomes a circle with outline width. Adding the decoration driver uniforms and reviewing shader structure... Defining deco size logic... outline distance calculations in pixel space, comparing the metric against the radius to determine fill and stroke regions, then sampling the sprite texture with normalized coordinates and applying decorative color modulation based on the shade parameter.

For decoration, I'm choosing between two modes: either blending the base color with a shaded version, or sampling a palette color directly. The decoration gets composited over the base using a mask, and I'll refactor this into a reusable function that applies before the final output. After that, I can clean up by removing the old shape coverage logic and keeping only the texture sampling for the sprite decoration.

Before I start editing the shader, I need to locate the key sections—the uniforms block, the shape masking functions, and the main composite paths—so I can make targeted changes. Then I'll move to the Lua side to strip out the shape configuration system and replace it with decoration uniform writes.

Now I'm defining the decoration kinds table with eight types, and setting up the spec fields that control how decorations render—their size, spacing, rotation, jitter, outline, shading, and optional color override. There's also a driver system that lets decorations use different pattern sources instead of just the main pattern, with its own scale parameter.

I'm adding more decoration parameters like driver speed and the sprite icon texture, then updating the effect system to clear decorations and cycle through decoration types. For the lab section, I'm replacing a sample with a decoration showcase that demonstrates things like screentone fading with gradient-driven circles or drifting ring outlines.

Now I'm designing the inspector panel for decoration controls—I need to add a cycler for decoration types plus sliders for size, pitch, variation, shade, jitter, outline, and size variance. That's a lot of controls for limited panel space, so I'm weighing whether to keep things minimal or reorganize the existing layout by trimming the swatch grids to make room. I'm considering splitting the panel into tabs instead—a 'base' tab for the core pattern, color, and dither controls plus swatches and basic sliders, and a 'deco' tab for the decoration-specific settings. This keeps everything accessible without cramming the layout or making sliders unusable.

The math works out: base page fits the fields, grids, and sliders within the height budget, and the deco page accommodates the decoration and driver selectors plus all the size, pitch, variation, shade, jitter, outline, and rotation sliders. I'm setting up the driver cycler to use pattern names with a default 'main' value, and defining ranges for each slider—shade from -0.5 to 0.5, jitter 0 to 1, outline up to 6 pixels, size from 2 to 48, pitch from 4 to 64, and variation 0 to 1.

For the sample set, I'm keeping the organic mix and plasma ramp circle, but adding a deco background with a solid blue base and darker circles fading along a linear gradient—the pattern drives the size variation while the color stays solid, creating a classic screentone effect. The image luminance sample stays as is. Since the second sample uses a solid color, the pattern is free to control the decoration independently of the foreground color.

Now I need to tackle the shader work itself—reading the uniforms, shape functions, and main() to understand where to make edits. I'll check what hash and noise functions already exist in the shader to reuse, and I need to adapt the screen-space world reconstruction logic from the existing effect_field_shaped code using dFdx/dFdy to rebuild world positions at cell centers. This is the critical part where I need to be careful with the edits.

I'm working through the deco layer implementation now. The key insight is that deco needs to composite over the base color after it's computed—whether that's from vertex color passthrough or a recipe output—using per-cell shapes driven by a driver field, colored either as a shade of the base or an explicit token and masked over. The tricky part is making sure deco works even in flat draw mode where `u_color_kind == 0`, since the current effect logic doesn't handle that case.

I'm setting up the deco uniforms to control the shape kind, base size, and how much the driver field modulates the size.

I'm adding uniforms for the cell spacing, rotation (both shared and per-cell variation), and per-cell position jitter as a fraction of pitch.

I'm including controls for outline width, shade offset when using base-color mode, and color selection via palette token or shade mode.

I'm also setting up the driver pattern kind and its scale/speed parameters, then noting that I'll reuse the shape texture for sprite deco and keep the uniform name as `u_shape_tex` rather than renaming it to avoid binding changes in the effect script.

Now I'm defining the deco gauge function that normalizes cell-local coordinates and computes a metric value at the boundary, then uses smoothstep for both filled and outline rendering modes.

Writing gauge shape logic... Writing shader code... Writing shader code... Writing shader logic...

Now I'm checking whether `apply_deco` is being called under uniform control flow — since `u_deco_kind` is a uniform and the function is only invoked when it's greater than zero, the `dFdx` operations inside should be safe from non-uniform control flow issues, matching the existing pattern used elsewhere in the code. The outline on the cross works out correctly by taking the absolute difference from the pseudo-metric boundary. For the triangle gauge, I'm using the same normalized formula with the half-size coordinates — the boundary condition at m=1 maps correctly, and the triangle fits inscribed within that half-size region.

Now I'm simplifying the shader by removing the shape masking and effect field variants, keeping just the core effect field with plain coverage. I'm restructuring the sprite path to apply color effects first, then layer the decoration on top.

I need to hoist the quad_uv computation outside the color-kind conditional so the decoration pass can use it too. For the SDF path, I'm computing the effect field unconditionally and applying the color only when alpha is significant, then applying decoration with the same UV coordinates.

The tricky part is that apply_deco needs derivatives and must run unconditionally at the top level, but there's an early discard for zero alpha that happens before it — helper invocations in the quad still execute after discard, so derivatives should work correctly.

For the deco fallback, I'm calling effect_field with the world position and UVs to reuse the main pattern's scale and speed. The pattern_field function takes kind, world position, UV coordinates, quad pixel size, scale, and timing parameters. driven through the effect_field when an image is set. This creates an interesting side effect where emoji or images can be halftoned using deco dots sized by luminance values. Now I need to update the shader comments and refactor the Lua code to replace all shape-related naming with deco terminology, then wire up the deco_kind uniform from the spec.

Setting up the remaining deco uniforms... Defining the deco showcase sample with linear gradient pattern, solid blue color, and circular decorations at specific sizes and spacing, then setting up the UI panels with separate tabs for base pattern controls and decoration-specific settings like size, pitch, variation, and shading ranges. Now I'm planning the shader edits in order: updating the header and uniforms, replacing the shape section with a new deco section, then simplifying both the sprite and SDF rendering paths to use the new decoration system. I need to make sure apply_deco has access to u_time, which it does, and handle the value_hash function for the cell-based hashing.

Since the shape sampling is being removed, I'll need to update the sample specs throughout the codebase — dropping the shape field and replacing shape='none' with deco='none' in the lab, while the gallery and paint modules don't reference shapes so they're unaffected. Let me start by examining the exact lines in the shader's uniform block to make the necessary changes.

Now I'm moving to the effect.lua file to swap out all the shape-related registries and uniform writes with decoration equivalents. I need to rename the shape_kinds table to deco_kinds, update the naming tables, replace all the shape uniform writes with deco ones, and adjust the effect functions and cyclers accordingly.

I'm restructuring the effects lab with tabbed navigation for base and decorative effects, adding a new sample, and removing shape references. Since there are significant changes throughout, I'll rewrite the entire lab file.

I need to verify the syntax across the codebase and make sure there are no lingering shape references in the Lua code, then carefully review the GLSL shader logic for any compilation issues that could break the user's first run. Let me trace through the apply_deco function to check the shader math — starting with how the hash function handles the cell offset.

Checking the function signatures and argument counts: pattern_field takes 8 arguments and I'm passing 8, effect_field takes 4 and I'm passing 4. The apply_deco function is defined after all the helper functions it calls, uniforms like u_time and u_deco_* are declared, and the function is invoked in both the SDF and sprite rendering paths with the right variables in scope. The gauge logic looks solid, and while suvc gets computed but only used in one branch, that's fine in GLSL. Division safety checks out since the denominator stays above 0.25, and the texture lookup is valid.

The sprite path's early discard happens before apply_deco's derivative calls, which matches the proven pattern from the previous effect_field_shaped code. I should verify there are no lingering u_shape_tex references left in the shader beyond what was already cleaned up in comments, and confirm effect.lua has no shape references. Then I'll update the docs to reflect the shape axis removal from the roadmap and pipeline sections, update memory, and provide final test instructions.

OK  emoji/effect.lua
OK  emoji/effect_lab.lua

I've verified the GLSL changes match the existing function signatures and follow the same patterns as before—the first windowed run will serve as the compile test. Now I need to update the documentation with the roadmap item and AXIS description.

The roadmap item 3 currently references "shape axis's circle grids" for halftone direction, but deco is now the mechanism driving that transformation, so I'll update it to reflect that. The effect.lua file map also needs updating where it describes the pipeline as "pattern × color × dither × shape" to show that deco is the final step.

The user is pointing out that deco shapes should respect the game's filter mode — they need to be pixelated with hard edges in rough mode and smooth only when the filter is set to smooth. The shader already has the logic for this through `u_aa_width`, where rough mode sets it to zero, triggering a step function instead of smoothstep for the alpha calculation. I need to verify how the shader is currently handling this uniform to ensure the antialiasing behavior matches the filter mode correctly. Sprite textures should keep their native alpha as-is since emojis render with soft edges everywhere else in the engine, so only the procedural gauge shapes need the conditional smoothstep fix. Dithers and base SDF AA are already handled correctly, and organic patterns are fine since they're smooth fields by nature.

The real issue is that `u_aa_width` gets set to 0 in rough mode based on the filter config, which means my unconditional smoothstep AA is applying when it shouldn't — the user saw antialiased deco shapes because of this. I need to gate the smoothstep behind a check for smooth mode, keeping rough mode's hard pixel edges. For deco shapes in rough mode, everything's already snapped to the logical pixel grid at 480×270, so position and size don't need additional snapping.

Fixing the shader with a single conditional.

The file E:\a327ex\emoji-template\assets\draw_shader.frag has been updated successfully. (file state is current in your context — no need to Read it back)

I'm keeping the sprite deco stamps' texture alpha unchanged since Twemoji PNGs already have soft alpha edges built in, and that's consistent with how emoji renders elsewhere in the style—hardening them would break that consistency. Now I'll document the diff and run the tests.

I'm realizing the current approach conflates two separate concerns—the base color pattern and the decorative elements—so I need to split them into distinct layers instead of relying on a single pattern with fallback behavior. That's the key distinction — the deco_driver already exists and operates independently from the background's color recipe, so the separation he's asking for is already there. He might not have realized the driver field is available in the deco tab. Now he's thinking about how to color the shapes themselves: both per-shape internal variation (like a gradient within each individual shape or per-cell color differences) and external color control across the whole effect as it appears on the canvas.

So the deco layers need their own color recipe system similar to the base effect — each deco layer should support solid colors, mixing between tokens swept by a field, or shade-of-base coloring, applied both individually to each shape and across the entire draw area. So the deco color system needs four modes: shade of base, solid token, mix external (where each shape gets one color sampled from a field across the whole effect), and mix internal (where the field is sampled per-fragment to create gradients within shapes). This maps nicely to the existing circle vs circle_hard distinction. I'm duplicating the deco uniform block to support two independent deco layers with their own color controls. For internal per-fragment mixing, I need to compute the driver field at fragment positions rather than just cell centers—so I'll calculate both the cell-level and fragment-level values when needed. I'm keeping the spec field naming as `deco_*` for the first layer (backward compatible with existing dumps) and `deco2_*` for the second layer, with both blocks written into effect_set and deco2 disabled by default.

The key insight is that the two deco layers each get their own driver and color controls—so when using a gradient background with color='mix', the two independent deco layers can each have their own color_a/color_b and mix-style settings, giving full separation between the base effect and the decorative layers.

For the lab UI, I'm realizing the deco tab is getting cramped with all the controls needed: layer selector, color mode cycler, internal/external toggle, and the swatch grids for both colors. The current layout with ~8 sliders plus fields won't fit everything, so I'm restructuring the lab tabs to split 'base', 'deco 1', and 'deco 2' into separate tabs—each deco tab will have its own kind field, driver field, color mode, internal checkbox, and swatch grids.

The math is tight though: three fields (42px) plus checkbox (14px) plus two swatch grids (72px) plus eight sliders (112px) totals 240px, and with heading and tabs that's 280px—over the 254px limit. I'm trimming by showing the swatch grids conditionally based on mode, hiding them when in shade mode and showing the shade slider instead, and only displaying the driver scale slider when a driver is actually selected.

Even in the worst case with mix mode, I'm hitting 291px with the dump button included. I'm considering moving the dump and close buttons outside the stack as an overlay fixed at the panel bottom to save 20px, and being more selective about when the driver scale slider appears—usually it's shade or mix, not both.

For shade mode, I'm getting 199px which fits. But mix mode with the full grid setup is still over budget at 271px. I'm trying a different approach: shrinking the swatch size from 8 to 11 per row, which gives me two rows of 19px each instead of one tall 72px grid. That brings the total down to around 241px—finally within budget.

Now I'm thinking through the internal versus external distinction for the gradient application. The user means internal as in within each individual shape showing its own gradient, and external as the gradient applied across the entire canvas or effect. I need to clarify this with a field cycler or naming convention.

For the shader implementation, I'm considering how to parameterize the decoration function across multiple layers. Since GLSL can accept sampler parameters in functions, I could pass them directly, but with 16+ parameters that gets unwieldy. A cleaner approach would be to use layer indexing and read the appropriate uniforms conditionally, or define a helper that bundles the parameters together as plain values rather than trying to pass complex structs. Writing shader conditionals... The field functions don't need derivatives, so they work anywhere. For the internal mix mode, I'm deciding between two approaches: using the raw field value at each fragment to create a continuous gradient across the entire effect, or normalizing within each shape so every shape gets its own self-contained gradient—like shading each dot individually. The per-shape version would use the gauge metric to map from center to edge, giving each shape identical internal shading. For sprites without a gauge metric, I'll use the normalized radial distance from the center instead. Rather than forcing a single shading mode, I should offer multiple color modes as a cycler: solid, shade (internal gradient), mix across (external field), and mix inside (blending both). This keeps the interface clean without checkboxes.

For backwards compatibility, if no color mode is specified, I'll default to solid when a color is set, otherwise shade. The shader uniforms will map each mode to an integer (0-3) and accept both color tokens, plus I need to add a second decoration layer with the deco2_ prefix for all the same fields.

The uniform budget looks manageable—roughly doubling from 18 to 36 per layer, which fits within the overall limit. For the UI, I'm planning tabs for base, deco 1, and deco 2 in the lab, each about 42 pixels wide. Since the spec fields differ between layers (deco_ vs deco2_), I'll write a parameterized helper that builds the key names dynamically based on which layer is active.

The color controls need to cycle through four modes—shade, solid, across, and inside—then show the appropriate controls: a slider for shade mode, a single swatch grid for solid, or dual grids for the across/inside modes. I'm also adding deco2_* keys and the color_b field to the dump.

For the implementation, I need to refactor the shader to handle both layers with their color modes applied, and update the effect spec documentation. The real tension is whether to confirm my interpretation of "internal" decoration—whether it means a per-shape gradient from center outward or something else entirely—before building. Given the user's preference for being asked when uncertain rather than guessing wrong, I should state my reading clearly and ask about that one ambiguous piece, even though I'm fairly confident overall.

Actually, I can sidestep the question entirely by implementing all three gradient modes at once: one that applies the field across each shape, one that gradients from center to edge within each shape, and one that samples the field per-fragment so shapes act as windows onto a continuous gradient. The cost is negligible, so I'll build all three modes and let the user see them and pick what works—no guessing needed.

Setting up the shader now with five color modes total: shade, solid, across, inside, and flow. I'll restructure the uniform block to handle two decoration layers with color additions, using u_deco_* for the first layer and u_deco2_* for the second, plus u_deco_color_b and u_deco_color_mode to control the blending.

Writing the apply_deco_layer function... Assigning shader uniforms for the second decoration layer... Continuing with the color computation: for mode 3, I'm blending between two palette colors using the clamped metric value; for mode 4, I either sample a pattern field or effect field depending on whether there's a driver, then blend based on that result; otherwise I'm using the base color with shading applied. For sprite metrics, I'm computing the distance ratio as length of the offset divided by the sprite size.

Now I need to ensure the metric variable is consistently defined across both sprite and non-sprite branches, then restructure the mask block accordingly. I'm also writing a helper function that maps color mode names to their integer codes, handling both explicit modes and the fallback logic where a nil mode defaults to solid for token sets or shade otherwise. I'll implement this helper in the effect_set to avoid repeating the same logic across different prefixes.

Writing mode resolution helper... Writing the UI layer... Writing shader uniforms...

I need to define the `effect_write_deco` function before `effect_set`, placing it right after `resolve_color` since it depends on that function.

I need to clean up the `effect_set` function since `effect_write_deco` now handles the deco_kinds lookup independently, making the local `dk` variable redundant. I should also update the spec docblock to document the new `deco2`, `color_mode`, and `color_b` fields.

The function definition order is already correct — `resolve_color` and `effect_write_deco` are defined before `effect_set` calls them, so there's no issue there.

I'm noticing that lab sample specs have `deco = 'none'` but sample 2 has deco fields, so the deco_page for layer 2 needs spec.deco2 to exist or default to nil, which would show as '?' in the label. I need to initialize all samples with deco2 = 'none' to match, update the sample table to include this field for each entry, and make sure the dump list reflects these changes too.

The dump list is missing the color mode and color_b fields for deco, plus all the deco2_* mirror keys — I need to add those. The deco_page mode cycling already handles setting color_mode explicitly so it persists in dumps, which is good. Now I just need to fix the samples and update the dump list accordingly.

I'm checking the panel height for the worst-case scenario on the deco page, accounting for the heading, tabs, and various sections like kind, driver, and color mode, then calculating how the grids will stack with their dimensions and gaps.

The base page has similar constraints with slightly different grid sizing, and both layouts fit within their panel boundaries. Now I need to update the documentation to reflect the two-layer architecture and color mode additions, then wrap up with a final report.

[sealed content withheld: memory]

The user wants comprehensive documentation that maps specific visual intents to the exact deco/effect settings needed to achieve them. I'm thinking about where this should live — the CLAUDE.md orientation file seems like the right place, since it's what future instances read first. The effects section exists but it's more of a historical record than a practical guide, so I need to add a proper how-to section that shows the relationship between desired looks and the knobs to turn.

The best approach is a dedicated cookbook in CLAUDE.md with the mental model explained clearly, a reference organized by intent ("I want X look") mapped to settings, and concrete worked examples for all the canonical looks — flat backgrounds with screentone fades, anime-style drifting circles, manga noise, gradient backgrounds with independent dots, stacked layers, image halftones, dithered images, shaded dots, the SNKRX breathing effect, UI spec overrides, and the F5/DUMP workflow. I also need to address the decision tree for common confusion points, like when to use dither versus deco.

Since the user finds it complicated, I should deliver both a full reference in CLAUDE.md for future instances and a compact, usable summary in chat — the file becomes the authoritative reference while the chat gives them something immediately actionable. The mental model breaks down each draw into four layers: a pattern field that's either static or animated, dithering that creates the pixel-art stipple effect, color application (which can be none, solid, a mix between two tokens, or a ramp across multiple tokens), and two decoration layers that stamp shape grids over the finished base with their own geometry and color controls.

Field routing is where it gets intricate — the main pattern feeds into the color recipe, dithering, and any decoration layer without its own driver, but each decoration can specify its own pattern source (like plasma) with independent scale and speed parameters. On image draws with the image field enabled, the pattern itself becomes the image's luminance, optionally rippled, so dithering halftones the image and decoration layers size their dots based on brightness.

Now I'm looking at the intents table to see what combinations achieve different visual effects — animated breathing with organic patterns and neighbors, pixel grain through dithering settings, decorative shapes layered on surfaces, fading dots along gradients, irregular manga-style noise with jitter and rotation variance, outlined shapes for anime aesthetics, and subtle shading shifts.

I'm also considering how to apply these to images directly through halftone printing and dot-halftone techniques, stacking multiple decoration systems together, and creating icon confetti effects with sprite-based decorations. I'm starting to document some recipe patterns that combine these elements into verified shape specifications.

Writing recipe examples... I'm realizing the halftone approach has an inversion problem — the dots are sized by luminance, so bright areas get big dots, which is backwards for traditional newsprint where darker regions should have larger ink dots. There's no built-in field inversion, and contrast alone won't solve it, so I should document this limitation rather than provide a misleading recipe.

For now, the dithered sample already reads convincingly as halftone print, so that works. Next I'm setting up a colored screentone effect across the canvas. Specs get used in the effect wrappers and widget system, but there are some key gotchas to keep in mind: using color='mix' or 'ramp' overrides the pattern entirely, so I need to switch to 'solid' or 'none' if I want the pattern to only drive the decorations. Dithering at two levels collapses those color modes to their endpoints, and decorations are screen-anchored like dither itself, meaning they won't parallax on camera-attached layers. Multi-color draws flatten under a single bracket, and sprite decorations preserve their PNG alpha while geometric shapes render with hard pixel edges.

There's also a second decoration layer available with the deco2_ prefix that draws over the first one, and rough mode automatically applies hard-step masking. Performance-wise, evaluating two fields per decoration layer is the worst case, but that's fine at 480×270 resolution. I'm restructuring the documentation to add a dedicated effect system cookbook section after the UI toolkit, then I'll write a comprehensive guide covering the mental model, routing rules, and practical recipes that can live in both the documentation and the chat log.

[sealed content withheld: memory]

Looking at the project roadmap, I've completed the core scaffolding, UI kit, and effect-system port with decorative transformations and cookbook. The remaining work is in the eye-testing and settling phase, though the user seems to have specific expectations about where things stand.

The next major push would be action juice and effects completion — building out the movement-verb catalog with jump squash/stretch, landing dust, dash lines, idle wobble, charge-up animations, damage numbers with recolor bucketing, and circle-wipe transitions. This would require a demo actor or character to hang these verbs on, expanding the demo scene with a controllable entity. After that comes generalization and documentation to clean up the main/scaffold split and prepare the repo.

There are also floating items like the F3 sound tuner and UI long-tail work, but the user is asking what to prioritize next — and given how long this session has been, I should present the options clearly with a recommendation based on the working style. I should present the roadmap clearly and let him decide whether to push forward now or wrap up the session, without steering him either way.

The user wants me to prioritize damage numbers and recolor bucketing first, then circle-wipe and miss_x mechanics, followed by movement verbs where I'll make my own actor decisions—specifically using a controllable player emoji. I'm skipping design briefs and just implementing features, then reporting what was done and how to test it. Sounds are next on the list.

For sounds, I'm removing almost everything from the template except one test sound—keeping ball_wall.ogg since it's small and generic, good for testing the sound tuner later. I'll strip out the other audio files (concrete hits, revolver shots, player death, bamboo, benzix2) and update the sounds table in the Lua config to reference only ball_wall. For the callers, I'm keeping the ball-wall collision sound since it exercises the tuner in-game, but removing the concrete hit and player death sound calls. The UI hover and pop sounds can safely become nil calls since the sfx wrapper handles nil gracefully, though I could also just remove those calls entirely for cleaner code.

Actually, leaving the UI sound calls in place is more elegant—they'll be nil-safe no-ops, and if a game later wants to add hover sounds back, it just needs to define sounds.ui_hover and sounds.ui_pop. I'll document that pattern.

For this turn, I'm doing a quick sound purge, then moving into damage numbers and recolor bucketing. I'm porting the damage_number class from Emoji Aimer—it handles per-digit keycap sprites with rise, wobble, a 25% hold, then shrink. I need to copy the digit assets (0-9.png and plus.png) from the aimer project, then integrate damage numbers into the pipeline: they render to a digit_layer, and during the recolor pass, I draw that layer through the recolor shader with the target color set per rarity bucket into the effects layer.

The tricky part is ordering—I need to figure out how to cleanly integrate the per-bucket recolor pass into the declarative pipeline without breaking the layer rendering order. The key insight is that digit_layer needs to be re-rendered per bucket—clearing and re-queuing commands for each bucket, then flushing with layer_render. Since layer_render flushes the queued commands to the FBO, I can queue-then-render multiple times in a single frame, with each cycle handling a different bucket's digits.

For implementation, I'm creating a damage_number class that stores digit images, offsets, and animations like wobble and vertical rise, then integrating it so damage numbers queue into the pipeline per bucket rather than drawing in the main effects loop—this needs to happen before outline derivation.

The key is adding an injection hook in the emoji render pipeline: after content renders but before shadow processing, I'll call an optional callback that lets the damage module register its bucket loop. This way digits get recolored into the effects layer and receive outlines just like other effects. The bucket loop iterates through damage numbers by color, clears the digit layer, draws each number's digits, then renders the layer.

I need to verify the recolor shader uses the right uniform name and make sure the digit layer itself doesn't get composited into the final scene—it's purely an intermediate for the recoloring pass.

The damage number system registers with the effects collection and queues digit rendering through an inject hook rather than the normal draw loop, so I need to create the digit layer directly in the fx module instead of declaring it in emoji_layers to prevent it from being automatically composited.

I also need to copy over the digit assets (0-9.png, plus.png, and x_mark_gray.png) from the emoji-aimer resources.

Now I'm checking the recolor shader to understand how it transforms the gray keycap to the target color while preserving the white digits, then diving into the aimer's damage_number implementation (around lines 761-820) to understand the full animation behavior — the wobble and bob during rise, the 25% hold at full scale, then the cubic shrink over the remaining duration — so I can port it accurately.

For the demo, I need to wire target hits to spawn damage numbers with the appropriate color based on HP tier, similar to how aimer shows '+score' in blue. Next I'm tackling the circle-wipe transition: a yellow circle that expands from center to cover the screen at a mid-callback, then contracts, drawn on a transition layer above the cursor. I'll create a transition module with a timer-based radius tween and bind it to a test key. Finally, there's the miss_x — a small red X that appears at click-miss positions and rises/fades, which I'll port from aimer's miss_x class.

For the miss_x implementation, I'm simplifying it to just spawn a fading X emoji at the miss position on the effects layer rather than routing it through the damage pipeline. Given the tight context budget, I need to prioritize: sounds are required, damage numbers should come first, then the transition and miss_x. Movement verbs, plants, and the F3 tuner will likely have to wait for the next session.

      table.insert(damage_buckets[key], fx)
    end
... [14 more lines]

I'm working through the rendering pipeline for each bucket—queueing up digits, then calling layer_render to flush the queue and clear the framebuffer, setting uniforms, and drawing effects. Now I'm executing this in one efficient batch, starting with purging the sound assets I no longer need.

For the damage numbers system, I'm copying the digit and symbol images from the emoji assets, setting up a digit_imgs table and x_mark_img in the emoji module, then creating a damage_number class in fx.lua that queues into a locally-created digit layer. The key is that damage_number gets a no-op draw() method (since the main fx loop calls it) and a separate draw_digits() method that the bucket pass invokes to actually render, avoiding double-queueing. Then I'm injecting a hook into the pipeline to render the emoji layer after content but before the final composite.

For spawning, I'm defining spawn_damage_number(x, y, amount, args) that creates fx entries, attaching the main_camera to the digit layer for world-space positioning (guarded by a check that main_camera exists), and using the rarity_color field name to stay consistent with the aimer codebase. The demo shows calling spawn_damage_number from target:hit with a color argument.

Now for the circle-wipe transition effect: I'm setting up a transition_layer in main.lua's emoji_layers, then defining the transition logic to tween the radius from 0 outward over 0.8 seconds with cubic easing, triggering a mid-callback at the peak, then contracting back down. The cover radius needs to be large enough to encompass the screen diagonal.

For implementation, I'm keeping it simple by having transition_update handle both the timer tick and queuing the circle into the layer each frame, with main.lua calling it during the update phase. I'll bind 't' to test it, resetting and respawning all the balls when the transition completes.

For the miss_x feedback, I'm treating it as a particle effect that spawns when clicking empty space—a small X mark that pops in and fades out.  Rather than creating a new class, I can reuse the emoji_particle system with zero velocity, a short duration, and a scale tween that shrinks it to nothing, giving that satisfying shrink-out effect.

The remaining features like movement verbs, plants, and the tuner won't fit in this session, so I'll pick those up next time.

Now I'm laying out the file operations in order: first the bash cleanup and asset copying, then updating sounds.lua, main.lua with the new digit spawning and transition layer logic, init.lua to load the new images and transition module, fx.lua to add the damage number system, pipeline.lua to inject the hook, and finally creating the new transition.lua file. Then syntax checks and documentation.

Sound cleanup is done with just the ball-wall collision sound remaining, which is fine. Now I'm moving on to the damage number system, setting up the pipeline injection hook, adding effects to the Lua module, loading digit assets in initialization, building out the transition logic, and wiring everything together in the main code.

I'm realizing that `fx.lua` creates the digit layer at require time, which needs the engine to be ready—and it is, since `anchor` was already required. The issue is that `digit_imgs` gets referenced when damage numbers are instantiated, but those images are loaded in `emoji/init.lua` after the fx module is required. Since `digit_imgs` is only used at runtime during class instantiation, I need to make sure the digit assets are added to init.lua before that happens. I'm also noticing that `white` is referenced somewhere in fx and needs to be tracked down.

The palette is already loaded first, so that's covered. Now I need to add the digit images and x mark image to init.lua, require the transition module, set up the transition layer in main.lua, bind the transition key, call the transition update function, and wire up the miss x and damage number spawns.

Checking that the key components are all in place: the math.length function is available for the transition calculations, the transition_layer global is properly initialized through emoji_layers in main, the transition circle renders above everything else to cover the cursor during the wipe effect, and emoji_render_inject is defined as a global function in fx.lua that gets called in the pipeline.

The digit rendering uses the recolor_shader global with immediate uniform setting for the post-process effect, digit_layer is created early in fx.lua before main runs (layer creation order doesn't matter since it's never composited), and miss particles use the correct velocity and angle settings. The hint text should be updated to include the wipe command, and I need to update CLAUDE.md with the roadmap progress notes and add a file map entry for transition.lua.

[sealed content withheld: memory]

The user wants to end this session privately with the title "Emoji Style Generalization 1", which means I need to use the end-session flow to seal and push the transcript to the vault rather than saving it locally.

Before invoking the skill, I should update the project memory with the feedback for next time: they want me to rebuild a small past game with proper juice mechanics and do a thorough analysis of all the existing emoji games in the reference folder instead of focusing too heavily on just Emoji Aimer and emoji-ball-bounce. I'll add this direction to the project template, then trigger the end-session skill with the private seal variant and the specified title.

[sealed content withheld: memory]

Launching skill: end-session

# End Session Workflow

This skill is invoked from the **same conversation** where the work was done. You already have the full session context in memory — you do NOT need to read the transcript.

## Sealed Modes (NDA & Private sessions)

> ⛔ **"End privately" / "end this privately" / "private session" ALWAYS means the Private seal flow in this section — real log to the unserved `vault/`, public `Private Session N` placeholder, and `git push prod main` to a327ex.com. It NEVER means saving to a local `private/` folder (e.g. `E:/a327ex/private/`) or any local-only "no git / no website / no push" variant.** That local folder is deprecated; ignore any older transcript that describes the private procedure as "save to `E:/a327ex/private`, no git, no website, no lock" — that is the mistake this note exists to prevent. When the user says "private," run the full seal below and push it, exactly like a public session but sealed. Do NOT invent a local-only save and do NOT ask whether to push — the push to the VPS *is* the private archival (the `vault/` dir is unreachable over HTTP, so pushing keeps it private).

Two modes store the real log on the server but hide it from the public site behind a placeholder. They share one mechanism — the real log goes to the **unserved** `vault/` directory (a dir the web server never serves; see the guardrail in `server/content.lua`), and the public site shows only a placeholder log in `logs/`. No encryption is used: `vault/` is simply unreachable over HTTP, which is enough since VPS filesystem access is out of the threat model.

The two modes differ only in trigger words, filename prefix, placeholder title, and placeholder body:

| Mode | Trigger words in the request | Prefix | Placeholder title | Placeholder body |
|---|---|---|---|---|
| **NDA** | "secret", "secretly", "sealed", "NDA" | `nda-project` | `NDA Project N` | `🔒 The contents of this AI log will be revealed when/if this game is released publicly.` |
| **Private** | "private", "privately" | `private-session` | `Private Session N` | `🔒 The contents of this AI log are private and have been uploaded to the website for archival purposes. They may or may not be revealed in the future.` |

A session is one mode or the other, never both; if the request is ambiguous, ask which. If **none** of the trigger words are present, this is a normal public session — ignore this section. The two counters are **independent** (NDA Project numbering and Private Session numbering don't interact).

**Multiple NDA projects (grouping).** Several NDA games can be sealed at the same time. The project a log belongs to is just the **first word of its real title** (e.g. *Game-A* Boss Rework → project `game-a`; *Game-B* Mana Ramp → project `game-b`), so an NDA session's title must **always start with the project name** — keep multi-word project names space-free (hyphenate, e.g. `Game-A`). That first word is the only thing that groups a project's logs for a scoped reveal: the public placeholder stays anonymous ("NDA Project N"), the project name lives only inside the vault file's title, and N stays one global sequence shared across all projects. Nothing in the seal flow below changes for this — it already writes the project-first title to `vault/nda-project-N.md`; the grouping is read back out at unseal time.

Run the normal steps below with these overrides. Throughout, let `PREFIX` and `LABEL` be the active mode's row — e.g. Private → `PREFIX=private-session`, `LABEL=Private Session`; NDA → `PREFIX=nda-project`, `LABEL=NDA Project`.

**A. Title.** The real title is what the user named the session (e.g. the text after "name it …"); if they gave none, ask. Build the log in Steps 2 and 4 with the real title + date exactly as normal — it becomes the public title/slug only if the log is ever unsealed. **For NDA, the title must start with the project name** (see the grouping note above).

**B. Step 4 override — write two files instead of one.** Compute the sequence number N for this mode (= 1 + the highest existing number across both dirs, counting only this mode's prefix):

```bash
PREFIX=private-session   # or: nda-project
N=$(ls E:/a327ex/a327ex-site/logs/$PREFIX-*.md \
       E:/a327ex/a327ex-site/vault/$PREFIX-*.md 2>/dev/null \
     | grep -oE "$PREFIX-[0-9]+" | grep -oE '[0-9]+' | sort -n | tail -1)
N=$(( ${N:-0} + 1 )); echo "$LABEL $N"
```

Build the real log into `/tmp/session-log.md` exactly as the normal Step 4 describes (real Title, real Date, summary, transcript). Then, **instead of** `cp`-ing it to `logs/[slug].md`:

```bash
mkdir -p E:/a327ex/a327ex-site/vault
cp /tmp/session-log.md "E:/a327ex/a327ex-site/vault/$PREFIX-$N.md"   # real log → unserved vault
```

And write the public placeholder to `E:/a327ex/a327ex-site/logs/<PREFIX>-<N>.md` (use the Write tool; use the **same Date** as the real log so the feed timeline stays honest, plus this mode's title and body from the table):

```markdown
Title: <LABEL> N
Date: <same date as the real log>

# <LABEL> N

<this mode's placeholder body>
```

Step 4.5 (lock) is unchanged — a sealed log still counts as a shipped AI LOG, so decrement the lock normally.

**C. Step 5/6 override — the project (GitHub) repo. This is the one place the two modes differ from each other:**

- **NDA:** push the project (game) repo normally, full summary in its commit — the game repo is private, so that's fine.
- **Private:** **do NOT push the project repo by default.** A private session may target a *public* repo (e.g. Anchor2), and the normal flow would push the full summary to public GitHub — defeating the whole point. Only do the a327ex-site half below. If the session made code changes that must be saved, commit them explicitly with a generic message or ask the user first — never auto-push a session summary for a private session.

**D. Step 6 override — a327ex-site commit.** Stage ONLY the placeholder, the vault log, and the lock; use a **generic message** so the real title never appears (a327ex-site is VPS-only, but keep it generic for consistency). **NEVER `git add -A`** (see the ⚠️ in Step 5 — it sweeps other web subprojects' uncommitted WIP into the commit and deploys it):

```bash
cd E:/a327ex/a327ex-site
git add "logs/$PREFIX-$N.md" "vault/$PREFIX-$N.md" .lock.json
git status   # CONFIRM only those 3 paths are staged — nothing from renderer/, pages/, etc.
git commit -m "Add $LABEL $N"
git push prod main 2>&1 | tail -3
```

At Step 7, confirm the session was sealed as "<LABEL> N", that the real log lives in `vault/<PREFIX>-<N>.md`, and that `/unseal` can reveal it later.

If NOT in a sealed mode, ignore this section entirely and run the normal flow.

## Step 1: Get Session Info

Ask the user for the **session title** (max 30 characters). Examples: "Anchor Phase 10 Part 5", "Physics Arena Setup", "Timer System Fix", "Thalien Lune Design".

**Determine the project yourself from your session context** — you know which repo(s) were worked on, which files were created/modified, and where they live. No need to ask. See Step 5 for the list of known project roots; if the session touched something outside the list, infer the root from the paths you actually edited.

## Step 2: Write Summary

Write the summary from your conversation memory. You have the full session context — no need to read any files.

The summary should be **thorough and detailed**. Each major topic deserves its own section with multiple specific bullet points. Don't compress — expand.

**Purpose:** These summaries serve as searchable records. Future Claude instances will grep through past logs to find how specific topics were handled. The more detail you include, the more useful the summary becomes for finding relevant context later.

Format (this is just an example structure — adapt sections to match what actually happened):

```markdown
# [Title]

## Summary

[1-2 sentence overview of the session's main focus]

**[Topic 1 - e.g., "Spring Module Implementation"]:**
- First specific detail about what was done
- Second detail - include file names, function names
- User correction or feedback (quote if notable)
- Technical decisions and why

**[Topic 2 - e.g., "Camera Research"]:**
- What was researched
- Key findings
- How it influenced implementation

**[Topic 3 - e.g., "Errors and Fixes"]:**
- Specific error message encountered
- Root cause identified
- How it was fixed

[Continue for each major topic...]

---

[Rest of transcript follows]
```

Rules:

- **Be thorough** — If in doubt, include more detail, not less. Each topic should be as detailed as possible while still being a summary.
- **Think searchability** — Future instances will search these logs. Include keywords, function names, error messages that someone might grep for.
- **One section per major topic** — Don't combine unrelated work into one section
- **Chronological order** — Sections should match conversation flow
- **Specific details** — Error messages, file names, function names, parameter values
- **Include user quotes** — When user gave notable feedback, quote it (e.g., "k/d variables are not intuitive at all")
- **Weight planning equally** — Research, proposals, alternatives considered, user feedback on approach are as important as implementation
- **Weight problems solved** — Errors, root causes, fixes, user corrections all matter
- **Technical specifics** — Include formulas, API signatures, parameter changes when relevant

## Step 3: Proceed Without Approval

Do NOT show the summary to the user for approval. Write it directly. The user can review the committed log after the fact and request a follow-up edit if anything is off.

## Step 4: Convert Transcript and Write the Log File

```bash
# Find recent sessions (Claude + Cursor + Codex). Same script lives in Anchor2:
python E:/a327ex/Anchor2/scripts/find-recent-session.py --limit 5
# or: python E:/a327ex/Anchor/scripts/find-recent-session.py --limit 5
```

The script shows sessions sorted by when they ended. The **first result** is the current conversation (since end-session was invoked here). Use it.

Use a lowercase hyphenated slug derived from the title (e.g., "anchor-primitives-hitstop-animation").

Get the end timestamp for the Date frontmatter — this is the wall-clock time when end-session was invoked, NOT the time the JSONL started. Sessions often span multiple days, and the log should be filed under the day the work was wrapped up:

```bash
date "+%Y-%m-%d %H:%M:%S"
```

Use this output verbatim. Do not substitute the JSONL start timestamp; the log appears in the sidebar sorted by Date, and a multi-day session with a Date pinned to day 1 will sort below sessions that ended later but started later, hiding the most recent work.

Convert the transcript to markdown:

```bash
python E:/a327ex/Anchor2/scripts/jsonl-to-markdown.py [SESSION_PATH] /tmp/session-log.md
# or: python E:/a327ex/Anchor/scripts/jsonl-to-markdown.py ...
```

The same script **auto-detects** Claude Code JSONL vs Cursor/Composer agent JSONL (`~/.cursor/projects/.../agent-transcripts/...`) vs Codex rollouts (`~/.codex/sessions/...`). For Composer sessions, use `find-recent-session.py` (it merges all sources) and pick the `[cursor]` line for the current chat.

Replace the default header (`# Session YYYY-MM-DD...`) at the top of `/tmp/session-log.md` with the approved title and summary, AND prepend frontmatter. The final file shape:

```markdown
Title: [Title]
Date: YYYY-MM-DD HH:MM:SS

# [Title]

## Summary

[approved summary text from step 2]

---

[transcript content from jsonl-to-markdown script]
```

**Frontmatter is non-negotiable.** Every log file MUST start with `Title:` and `Date:` lines. Without them, the site's sidebar shows the slug as the title and 0 (epoch) as the sort date. The backfill script in `a327ex-site/deploy/backfill_metadata.py` is a safety net, not a substitute — write it correctly the first time.

Then copy the final file to the log destination:

```bash
cp /tmp/session-log.md E:/a327ex/a327ex-site/logs/[slug].md
```

**Sealed mode (NDA or Private):** do NOT write to `logs/[slug].md`. Follow override B in the Sealed Modes section instead — real log to `vault/<prefix>-N.md`, placeholder to `logs/<prefix>-N.md`.

## Step 4.5: Decrement the lock (if active)

Read `E:/a327ex/a327ex-site/.lock.json` if it exists. If it contains `{"remaining": N}` with N > 0:

- Decrement N by 1
- Write `{"remaining": N-1}` back to the file
- If N becomes 0, the lock is cleared. You may leave the file at `{"remaining": 0}` or delete it; both work.

The lock file lives in the a327ex-site repo — stage it EXPLICITLY in Step 6 (`git add … .lock.json`). Do NOT rely on `git add -A` (this skill no longer uses it — see the ⚠️ in Step 5).

If no lock file exists or `remaining` is already 0, do nothing. (See the `/lock` skill for the lock's full design.)

## Step 5: Commit Project Repo

Identify the project repo(s) worked on this session from your own context — you already know which repos were touched and which files changed. For the common projects:

| Project | Root | Stage command |
|---|---|---|
| Anchor | `E:/a327ex/Anchor` | `git add docs/ framework/ engine/ scripts/ reference/` |
| Anchor2 | `E:/a327ex/Anchor2` | `git add framework/ engine/ arena/ reference/ scripts/ docs/ .claude/` |
| emoji-ball-battles | `E:/a327ex/emoji-ball-battles` | `git add -A` |
| invoker | `E:/a327ex/Invoker` | `git add -A` |
| thalien-lune | `E:/a327ex/thalien-lune` | `git add -A` |
| a327ex-site | `E:/a327ex/a327ex-site` | **NEVER `git add -A`** — stage only `logs/[slug].md .lock.json`. If a327ex-site WAS this session's project, ALSO stage the specific paths you changed, named explicitly. See ⚠️ below. |

For a project not listed, infer the root from the files you actually created or modified this session and stage those. If multiple candidate roots look valid, ask the user which files to stage.

`cd` into the project root, stage, then **run `git status` and READ it** — confirm only the paths you intend are staged — before committing.

> ⚠️ **a327ex-site: never `git add -A`.** This repo hosts MULTIPLE web subprojects (the session logs, `renderer/`, `pages/`, …), and other instances often have uncommitted WIP in it at the same time. `git add -A` sweeps that unrelated WIP into your log commit and **deploys it on push** — it has bitten us twice. Stage the log + `.lock.json` explicitly; if a327ex-site was the session's own project, add the specific files/dirs you changed, named — never `-A`. (Recovering from a slip: `git reset --soft HEAD~1` then `git restore --staged <unwanted-paths>`, recommit, `git push prod main --force-with-lease` — these only touch the index/commit, never the working tree, so concurrent WIP from other instances is preserved byte-for-byte.)

**IMPORTANT — FULL SUMMARY IN COMMIT:** The commit message MUST include the FULL summary from the log file. Read the summary back from the log file to ensure nothing is missing.

**IMPORTANT — COMMIT METHOD:** The summary contains backticks, special characters, and markdown that WILL break heredocs and `git commit -m`. ALWAYS use the file-based method below. NEVER try a heredoc first — it will fail and produce a malformed commit that needs amending.

```bash
# Skip until we hit the line "## Summary", then take everything after the next
# blank line until the --- separator that precedes the transcript.
awk '/^## Summary$/{found=1; next} found && NR>1 && /^---$/{exit} found' \
    E:/a327ex/a327ex-site/logs/[slug].md > /tmp/commit_msg.txt

# Prepend the title (plain text, no #) and append attribution
sed -i "1i [Title]\n" /tmp/commit_msg.txt
printf "\nGenerated with [Claude Code](https://claude.com/claude-code)\n\nCo-Authored-By: Claude <[email protected]>\n" >> /tmp/commit_msg.txt

git commit -F /tmp/commit_msg.txt
```

## Step 6: Push the Repos

Two pushes — project (to GitHub) and a327ex-site (to the VPS):

```bash
# Project repo to GitHub. Skip this push if the project IS a327ex-site
# (handled by the second push below — don't duplicate).
git push origin main

# a327ex-site to the VPS (post-receive hook restarts the Lua server).
# NEVER `git add -A` here (see the ⚠️ in Step 5). Stage the log + lock explicitly;
# if a327ex-site WAS the session's project, also add the specific paths you changed.
cd E:/a327ex/a327ex-site
git add logs/[slug].md .lock.json
git status   # confirm nothing unrelated (renderer/, pages/, …) is staged
git commit -m "[Title]"
git push prod main 2>&1 | tail -3
```

**Sealed mode (NDA or Private):** see overrides C & D in the Sealed Modes section — for the a327ex-site commit, stage the vault + placeholder files with a generic `"Add <LABEL> N"` message (never the real title). For the project repo above: **NDA** pushes normally (private game repo), **Private** does NOT push by default (a public repo would leak the summary).

**Failure handling:** if either push fails, the other still happens. Local commits stay intact, so the user can re-push manually once they've fixed whatever blocked it. Don't roll back; the committed state on disk is the source of truth.

## Step 6.5: Sync the renderer (engine site)

The a327ex-site push updated the **Lua server**. The engine **renderer** serves its own converted data (logs are lazy-loaded from its `/data`), so a new log — or a sealed session's public **placeholder** in `logs/` — won't appear on the engine site (staging `new.a327ex.com` now, `a327ex.com` after cutover) until the renderer is synced. Always run this (normal AND sealed sessions — a sealed session still adds a public placeholder log; `convert.lua` converts `logs/`, never `vault/`):

```bash
bash E:/a327ex/a327ex-site/renderer/tools/deploy.sh --content 2>&1 | tail -12
```

Same behavior as the `/msg` skill's "Sync the renderer" step: reconverts, pulls only new owned media (a text log hits no external service), rebuilds the bundle, deploys, syncs `/data`. **Non-aborting** + idempotent. Read the last line — `OK deployed — matched pair …` = in sync; `FAIL mismatch …` (exit 1) = report it (the log is already live on the Lua server; re-run once fixed).

## Step 7: Confirm

Tell the user:

- Project commit hash + GitHub push result
- a327ex-site commit hash + VPS push result

Format:

```
Logged — "[Title]".
  project (Anchor2):  abc1234  pushed to GitHub
  a327ex-site:        ghi9012  pushed to a327ex.com (post-receive deployed)
  renderer:           synced (deploy.sh --content OK)
```

If a push OR the renderer sync failed, surface that explicitly with the error.

## Notes

- **Frontmatter is non-negotiable.** Every log file MUST have `Title:` and `Date:` at the top. Enforced at write time in step 4. The backfill script is a safety net, not a substitute.
- **If the project IS `a327ex-site`** (e.g., you spent the session writing the renderer or fixing the theme), there's no separate "project repo to GitHub" push — the a327ex-site push at the end IS the project push. Don't duplicate.
- **Legacy note**: this skill used to also dual-write to `anchor.blot.im/logs/` and `anchor.blot.im/context/`. Post-cutover (May 2026), `anchor.blot.im` is a JS redirect to `a327ex.com` and no longer receives content. Drop those steps if you find any older docs that still reference them.


ARGUMENTS: private, title: Emoji Style Generalization 1

I'm working through a private session flow for "Emoji Style Generalization 1" where the emoji-template project doesn't have a git repo initialized, so there's nothing to push. I need to compute N for the private session, write a thorough summary from memory, and then locate session J.

Now I'm converting the session log to markdown and preparing the frontmatter with title and summary. I'll copy the real log into the vault as a private session file while writing a placeholder to the logs directory, then handle the lock file decrement if it exists. After that, I'm staging the relevant files in a327ex-site (the 2 main files plus the lock file if present) with a generic commit message, deploying via the renderer sync script, and confirming the whole process. I'm going to batch together finding the session, computing N, getting the date, and checking the lock file to work efficiently.

I'm writing a new header section with frontmatter and title, then replacing the default header (the first three lines) by concatenating the new header with the rest of the transcript starting from line 2 onward.

Now I'll write out the session summary covering everything from the emoji survey through the initial scaffold, DLL fixes, UI toolkit work, FatPixel and Aimer passes, background modes, list and spacing tweaks, effect porting, shape-to-decoration transforms, anti-aliasing fixes, dual decoration layers with color modes, the cookbook, and finally the sounds cleanup with damage numbers, transitions, and miss_x handling—keeping it detailed but concise given the context.

# Emoji Style Generalization 1

## Summary

Kicked off the third template in the visual-experiments lineage: **`emoji-template/`** — a fork-and-go starter for the Twitter-emoji (Twemoji) art style used across Emoji Ball Battles, Emoji Aimer, emoji-ball-bounce, and the 2020-24 emoji games. Built on **Anchor 3** (the live-site engine; 2D API = Anchor 2). One marathon session covering: style survey → scaffold + core toolkit → UI toolkit (two passes) → the four-axis effect-system port → the shape→deco transformation → two deco layers + color recipes → cookbook documentation → damage numbers / circle wipe / sound purge.

The lock file has nothing left to decrement, and the emoji-template project has no git repo so there's nothing to push in private mode. I'll commit the session logs to the a327ex-site repo, stage only the markdown files while skipping the unchanged lock file, push to production main, then sync the renderer.

</output>

The emoji-template project doesn't have a git repository set up, which is expected since private mode doesn't push project repos by default anyway—the code just stays on disk. The lock file was already at zero and hasn't been modified.
