Check current API quick references and the game's own anchor/ implementation before coding.\r\n\r\nanchor.cmd on PATH runs Anchor/workflow/anchor.py. Use anchor drive start GAME, anchor drive eval GAME --file SCRIPT, and anchor drive stop GAME for a hidden, externally stepped instance. The cmd.exe wrapper can strip embedded double quotes from inline Lua passed through PowerShell; use --file for nontrivial code. Start in an isolated fixture for setup checks; do not attach to the owner's live game. Announce captures. engine_state() exposes agent/visible/frame; engine_snapshot(PATH) captures a frame. Preserve the .apr recording. Playtesting and feel remain the owner's.\r\n\r\nUse anchor framework status/diff to inspect drift; make per-file upgrades only within authorized scope. anchor check requires LuaLS, which was absent in this setup check; report missing tooling rather than claiming a pass. Windows builds use engine/build.bat; verify compiler availability before running it. Engine/web builds and install/launcher/hook/service changes are separate from setup inspection while Claude owns migration.\r\n# Reverse Minesweeper — Codex workspace\n\nThis folder is Codex's independent working copy, recovered at the owner's request\non 2026-09-11.

See `FRAMEWORK_API.md` for\ndetailed documentation with examples, and `3D_API.md` for the raw 3D C bindings\n(`physics3_*`, `mesh3_create`/skinning/morphs, `layer3_*` engine-side).\n\n**Architecture.** Anchor 3 is the Anchor 2 framework plus a 3D tier. It is\nmostly procedural: most modules are plain functions that take state as the\nfirst argument (e.g. `timer_update(self.timer, dt)`). The only framework\nclasses are `collider` / `collider3` (body+shape bundling; 2D adds steering\nbehaviors) and thin wrappers around resource handles (`font`, `spritesheet`,\n`image`). Game entities are your own classes created with `class()`.\n\n**No `an` god-object. No object tree. No action phases.** The game owns its\nmain loop; update and draw are top-level globals the engine calls directly.\n\nThe 3D tier lives beside the 2D one: its own Box3D physics world beside the\nBox2D world, and a 3D scene layer type that renders into a standard layer's\nFBO. A game can use either or both. 3D conventions: **meters, y-up,\nright-handed**; rotations are quaternions passed as 4 numbers `qx, qy, qz, qw`;\ncolors are the same packed integers as 2D.\n\n---\n\n## Initialization\n\n```lua\nrequire('anchor')({\n  width = 480,        -- game resolution width (default: 480)\n  height = 270,       -- game resolution height (default: 270)\n  title = \"My Game\",  -- window title (default: \"Anchor\")\n  scale = 3,          -- initial window scale (default: 3)\n  vsync = true,       -- vertical sync (default: true)\n  fullscreen = false, -- start fullscreen (default: false)\n  resizable = true,   -- window resizable (default: true)\n  filter = \"rough\",   -- \"rough\" or \"smooth\" (default: \"rough\")\n  render_uncapped = false,  -- false (default): cap render at 60Hz for\n                            --   chunky pixel-art motion on high-refresh\n                            --   monitors.\n                            -- true: render every main-loop iteration;\n                            --   vsync paces the rate. Recommended for\n                            --   smooth-filter / non-pixel-art games where\n                            --   the cap shows visible judder.\n  display = 0,              -- monitor to open the window on. 0 = primary,\n                            -- 1+ = secondary. Out-of-range falls back to 0.\n  web_native_resolution = false,  -- web only: render at the browser canvas's\n                            -- pixel size (1:1) instead of scaling a fixed\n                            -- width/height to fit (that downscale blurs text).\n})\n```\n\nReturns nothing. Side effects: initializes the engine, populates global state,\nand registers module functions. After the call, all framework functions and\nengine bindings are available as globals.\n\n---\n\n## Global State\n\n### Static (set at init)\n```\nwidth, height        -- int, game resolution\nplatform             -- string, \"windows\" | \"web\"\nheadless             -- bool, headless mode flag\nrender_mode          -- bool, offline render mode flag\nengine_args          -- table of parsed command-line arguments\n```\n\n### Dynamic (refreshed by sync_engine_globals)\n```\nframe_num            -- int, current render frame\nstep_num             -- int, current physics step\ntime                 -- number, elapsed game time (seconds)\nunscaled_dt          -- number, raw fixed timestep\nwindow_width         -- int, actual window width in pixels\nwindow_height        -- int, actual window height in pixels\nscale                -- int, current integer render scale\nfullscreen           -- bool, window fullscreen state\nfps                  -- number, current FPS\ndraw_calls           -- int, draw calls from previous frame\ntime_scale           -- number, global time scale (set via set_time_scale)\n```\n\n### Resource tables (populated by resource loaders)\n```\nlayers               -- { name: layer }  (layer3_new also registers here)\nfonts                -- { name: font }\nimages               -- { name: image }\nspritesheets         -- { name: spritesheet }\nsounds               -- { name: sound handle }\nsound_paths          -- { name: path string }\nmusic_tracks         -- { name: music handle }\nshaders              -- { name: shader handle }\nentities             -- { id: entity }, populated by make_entity\n```\n\n---\n\n## Main Loop\n\nThe game defines two globals; the C engine calls them directly each frame.\n\n```lua\nfunction update(dt)\n  sync_engine_globals()   -- refresh time/frame/fps mirrors\n  -- game update: entity updates, timer_update, camera_update, etc.\n  -- physics is stepped by the engine BEFORE this runs; read collision events here\n  process_destroy_queue() -- drain deferred kill() calls\nend\n\nfunction draw()\n  -- queue draws via layer_* functions\n  -- then layer_render(lyr) + layer_draw(lyr) for each layer\nend\n```\n\n```\nsync_engine_globals()             -- refresh mirrors; call at top of update\nprocess_destroy_queue()            -- call at end of update; drains kill queue\ncollection_update(list, dt, [m])   -- update a list of entities; removes _dead entries\nset_time_scale(scale)              -- global time scale (affects scaled dt; unscaled_dt unchanged)\n```\n\n---\n\n## Classes and Entities\n\n### class() — minimal class helper\n```\nclass() -> class_table\n  -- Calling the class_table constructs an instance; :new(...) is the constructor.\n  -- No inheritance. To specialize, copy and modify.\n```\n\n```lua\nseeker = class()\nfunction seeker:new(x, y) self.x = x; self.y = y end\nlocal s = seeker(10, 20)\n```\n\n### make_entity / kill / destroy queue\n```\nmake_entity(e) -> e                -- assigns e.id and registers in entities[]\nentity_kill(e)                     -- free-function equivalent of e:kill()\nprocess_destroy_queue()            -- drain kill queue; calls each entity's :destroy()\n```\n\nAn entity's `:destroy` method is called from `process_destroy_queue`. Override\nit to free sub-resources (colliders, etc.) explicitly — there is no auto-cleanup\ncascade. `_dead` is set after destroy; `_dying` is set between kill and destroy.\n\n---\n\n## Input (aliases over engine C bindings)\n\n```\nbind(action, control)               -- control: 'key:a', 'mouse:1', etc.\nunbind(action, control)\nunbind_all(action)\nbind_chord(name, actions)\nbind_sequence(name, sequence)\nbind_hold(name, duration, source_action)\n\ninput_down(action) -> bool\ninput_pressed(action) -> bool\ninput_released(action) -> bool\ninput_axis(neg, pos) -> number\ninput_vector(left, right, up, down) -> x, y\ninput_hold_duration(name) -> number\ninput_last_type() -> string\ninput_pressed_action() -> string | nil\n\ninput_capture_start()               -- begin rebind UI capture\ninput_capture_get() -> string | nil\ninput_capture_stop()\ninput_deadzone(d)                   -- set gamepad deadzone\n```\n\nRaw mouse/keyboard queries (engine C functions, always available):\n```\nkey_is_down(key), key_is_pressed(key), key_is_released(key)\nmouse_is_down(button), mouse_is_pressed(button), mouse_is_released(button)\nmouse_position() -> x, y\nmouse_delta() -> dx, dy\nmouse_wheel() -> wx, wy\ngamepad_is_connected() -> bool\ngamepad_get_axis(axis) -> number\n```\n\n---\n\n## Resources\n\n### Fonts\n```\nfont_register(name, path, size, filter?) -> font\n  -- Also stores in fonts[name]. Font has {name, size, height, ascent}.\n  -- filter: 'smooth' (grayscale atlas + linear) or 'rough' (1-bit mono +\n  -- nearest); defaults to the engine's global filter mode. Baked into the\n  -- atlas at load — load two copies if you need both.\n\nfont:text_width(text) -> number\nfont:char_width(codepoint) -> number\nfont:glyph_metrics(codepoint) -> {width, height, advance, bearingX, bearingY}\n```\n\n### Images\n```\nimage_load(name, path, filter?) -> image | nil\n  -- Also stores in images[name]. Image has {handle, width, height}.\n  -- filter 'smooth'/'linear' = mipmapped linear; default = nearest (pixel art).\n  -- Returns nil on web while the async fetch is pending — caller retries.\n\nimage_load_fit(name, path, w, h) -> image | nil\n  -- Load resampled (high-quality, gamma-correct) to at most (w, h) device\n  -- pixels. Use with the engine's image_info(path) for layout-first sizing.\n```\n\n### Spritesheets\n```\nspritesheet_register(name, path, frame_width, frame_height) -> spritesheet\n  -- Also stores in spritesheets[name].\n  -- Spritesheet has {handle, frame_width, frame_height, frames}.\n```\n\n### Sounds and music\n```\nsound_load(path) -> handle          -- engine C function; handle stored directly in sounds[name] by you\nsound_play(handle, volume?, pitch?) -- engine C function\nmusic_load(path) -> handle\nmusic_play(handle, loop?, channel?)\nmusic_stop(channel?)\n```\n\n---\n\n## Layers\n\nCreated via `layer_new(name)` returning a layer state table `{name, handle,\nfilter, parallax_x, parallax_y}`. All `layer_*` functions take that table as\nthe first argument. Globals such as `layer_rectangle` shadow engine C functions\nwith userdata-first signatures; the wrappers accept both tables and raw handles.\n\n### Creation\n```\nlayer_new(name, filter?, w?, h?) -> layer   -- also stores in layers[name]\n  -- filter: 'smooth' (antialiased, linear sampling) or 'rough' (hard edges,\n  --   nearest). Defaults to the engine's global filter mode.\n  -- w, h: optional fixed size — the layer keeps this resolution regardless of\n  --   window/canvas resizes (e.g. window-resolution post-process passes).\n```\n\n### Drawing primitives\n```\n-- ⚠ ORIGIN: rectangles/text use TOP-LEFT (x,y); images/sprites/circles use\n--   CENTER (x,y). So layer_rectangle(x,y,w,h) draws from the top-left corner,\n--   but layer_image(img, x,y) centers on (x,y). Do NOT subtract half-size to\n--   \"center\" an image — it already centers (that double-offsets it up-left).\n--   Center an icon in a top-left box {x,y,w,h}: layer_image(lyr,img,x+w/2,y+h/2).\nlayer_rectangle(lyr, x, y, w, h, color)\nlayer_rectangle_line(lyr, x, y, w, h, color, line_width?)\nlayer_rectangle_gradient_h(lyr, x, y, w, h, color1, color2)\nlayer_rectangle_gradient_v(lyr, x, y, w, h, color1, color2)\nlayer_rounded_rectangle(lyr, x, y, w, h, radius, color)\nlayer_rounded_rectangle_line(lyr, x, y, w, h, radius, color, line_width?)\nlayer_circle(lyr, x, y, radius, color)\nlayer_circle_line(lyr, x, y, radius, color, line_width?)\nlayer_capsule(lyr, x1, y1, x2, y2, radius, color)\nlayer_capsule_line(lyr, x1, y1, x2, y2, radius, color, line_width?)\nlayer_line(lyr, x1, y1, x2, y2, width, color)\nlayer_triangle(lyr, x1, y1, x2, y2, x3, y3, color)\nlayer_triangle_line(lyr, x1, y1, x2, y2, x3, y3, color, line_width?)\nlayer_polygon(lyr, vertices, color)\nlayer_polygon_line(lyr, vertices, color, line_width?)\n```\n\n### Textures, sprites, text\n```\nlayer_image(lyr, image, x, y, color?, flash?)\nlayer_texture(lyr, tex_handle, x, y, color?)\nlayer_spritesheet(lyr, sheet, frame, x, y, color?, flash?)\nlayer_animation(lyr, anim, x, y, color?, flash?)\nlayer_text(lyr, text, font, x, y, color)\n  -- font may be a font table or a font name string\n```\n\n### Transform stack\n```\nlayer_push(lyr, x, y, r, sx, sy)   -- translate, rotate, scale\nlayer_pop(lyr)\n```\n\n### Blend and stencil\n```\nlayer_set_blend_mode(lyr, mode)\nlayer_stencil_mask(lyr)\nlayer_stencil_test(lyr)\nlayer_stencil_test_inverse(lyr)\nlayer_stencil_off(lyr)\n```\n\n### Shaders (see engine API for shader loading)\n```\nlayer_apply_shader(lyr, shader)\nlayer_shader_set_float(lyr, shader, name, value)\nlayer_shader_set_vec2(lyr, shader, name, x, y)\nlayer_shader_set_vec4(lyr, shader, name, x, y, z, w)\nlayer_shader_set_int(lyr, shader, name, value)\nlayer_shader_set_texture(lyr, shader, name, tex_id, unit?)\nlayer_reset_effects(lyr)\n```\n\n### Rendering pipeline\n```\nlayer_render(lyr, clear?)           -- process queued draw commands into layer's FBO\n  -- clear defaults to true.

A color is a plain table {r, g, b, a} with\n  a __call metamethod that returns the packed rgba integer used by drawing\n  functions. No auto-sync between RGB and HSL — HSL is a *conversion*, not a\n  storage format. If you want to modify hue, convert to HSL, modify, convert\n  back.\n\n  Usage:\n    red = color_new(255, 0, 0)\n    red.a = 128              -- set alpha\n    layer_circle(game_layer, x, y, r, red())  -- __call returns packed rgba integer\n    layer_circle(game_layer, x, y, r, red)    -- also fine: layer wrappers pack a Color table\n\n    -- HSL manipulation:\n    h, s, l = color_to_hsl(red)\n    h = (h + 120) % 360      -- shift hue\n    shifted = color_from_hsl(h, s, l, red.a)\n\n    -- Common operations:\n    copy = color_clone(red)\n    mixed = color_mix(red, blue, 0.5)\n    dark = color_darken(red, 0.5)      -- multiply RGB by 0.5\n    light = color_lighten(red, 1.5)    -- multiply RGB by 1.5 (clamped)\n    inverted = color_invert(red)\n\n  Design notes:\n    - Colors are plain tables. Modify fields directly: c.r = 100.\n    - Procedural functions (color_mix, color_clone, etc.) return NEW colors,\n      not mutating the input. If you want to mutate, do `c.r = ...` directly.\n    - __call returns the packed rgba integer via the engine's rgba() function.\n    - HSL is available via conversions, not as first-class color fields.\n    - Raw C bindings still want the packed integer: call the color (`c()`)\n      when passing one to an unshadowed engine function.\n]]\n\n---@class Color\n---@field r number   0-255\n---@field g number   0-255\n---@field b number   0-255\n---@field a number   0-255\n---@operator call: integer   packs to the rgba integer the engine draws with\n\n-- Internal: rgb_to_hsl and hsl_to_rgb\n---@param r number   0-255\n---@param g number   0-255\n---@param b number   0-255\n---@return number h   0-360\n---@return number s   0-1\n---@return number l   0-1\nfunction rgb_to_hsl(r, g, b)\n  r, g, b = r/255, g/255, b/255\n  local max = math.max(r, g, b)\n  local min = math.min(r, g, b)\n  local l = (max + min)/2\n  if max == min then return 0, 0, l end\n  local d = max - min\n  local s = l > 0.5 and d/(2 - max - min) or d/(max + min)\n  local h_offset = g < b and 6 or 0\n  local h\n  if max == r then\n    h = ((g - b)/d + h_offset)/6\n  elseif max == g then\n    h = ((b - r)/d + 2)/6\n  else\n    h = ((r - g)/d + 4)/6\n  end\n  return h*360, s, l\nend\n\n---@param h number   0-360\n---@param s number   0-1\n---@param l number   0-1\n---@return integer r\n---@return integer g\n---@return integer b\nfunction hsl_to_rgb(h, s, l)\n  if s == 0 then\n    local v = math.floor(l*255 + 0.5)\n    return v, v, v\n  end\n  h = h/360\n  local q = l < 0.5 and l*(1 + s) or l + s - l*s\n  local p = 2*l - q\n--[[\n  font — thin wrapper over C font functions.\n\n  Usage:\n    fonts.main = font_register('main', 'assets/monogram.ttf', 11)\n    layer_text(game_layer, \"Hello\", fonts.main, 100, 50, color)\n\n  A font is a plain table with .name, .size, .height plus query methods.\n  Stays as a simple class/struct pattern for consistent access.\n]]\n\n---@class Font\n---@field name string      the engine font name (what the raw font_* bindings take)\n---@field size number\n---@field filter string|nil\n---@field height number    line height in pixels\n---@field ascent number\n---@field text_width fun(self: Font, text: string): number\n---@field char_width fun(self: Font, codepoint: integer): number\n---@field glyph_metrics fun(self: Font, codepoint: integer): table\n\nfont = class()\n\n--- `filter` is optional: 'smooth' (grayscale atlas + linear sampling) or\n--- 'rough' (1-bit mono atlas + nearest sampling).

Its worked examples are beside it at\n[references/rounds.md](C:/Users/a327e/Desktop/a327ex/Anchor/workflow/claude/skills/iterate/references/rounds.md).\n\nCodex specifics:\n\n- Deliver artifacts with absolute Markdown file links; each delivered version at its own path.\n- These links are Codex's artifact handover records. Anchor converts each HTML handover into an individual artifact card immediately before that reply in the published log; no Claude-only display tool is needed. A collection page at the end supplements those cards. Keep both the individual handover links and the collection when one exists, and verify per-handover cards during publication through the end-session skill.\n- Follow the [Anchor skill](C:/Users/a327e/.agents/skills/anchor/SKILL.md) for hidden instances, captures and preserved replays.\n- An agreed round direction authorizes implementation within its scope without a further approval pause.\n- Session publication stays separate work under the [end-session skill](C:/Users/a327e/.agents/skills/end-session/SKILL.md).\n\n## Open HTML handovers in Chrome\n\nWhenever you deliver an HTML artifact, send its absolute Markdown file link and\nalso open that same preserved version in the owner's Google Chrome. This is\nstanding authorization for the handover; no additional confirmation is needed.\nUse Chrome, not Codex's internal browser or file-preview panel.\n\nSince tools run before the final reply, first post a short commentary message\nwith the artifact link, then open it in Chrome, then include the same link in\nthe final handover. Opening the browser supplements the file link; the link is\nstill needed for the later session log. Follow a specific request not to open\nthe browser on a particular handover.\n\nLaunch the installed Chrome executable with the preserved artifact's file URL,\nusing the normal Chrome session. The verified executable on this machine is\n`C:/Program Files/Google/Chrome/Application/chrome.exe`; if it is unavailable,\nresolve Chrome's registered executable again. For example, in PowerShell:\n\n```powershell\n$artifactPath = (Resolve-Path -LiteralPath 'C:\\absolute\\path\\rounds\\01-example\\index.html').Path\n$artifactUrl = ([System.Uri]$artifactPath).AbsoluteUri\nStart-Process -FilePath 'C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe' -ArgumentList @('--new-tab', $artifactUrl)\n```\n\nDo this for each new or revised HTML artifact being handed over, using its own\npreserved path. Reading an old artifact does not require reopening it. If the\nlaunch fails, report that and retain the link rather than silently opening the\ninternal Codex browser instead.\ntotal 138M\n-rw-r--r-- 1 a327e 197609 3.5M Sep  5 20:40 anchor\n-rw-r--r-- 1 a327e 197609 3.4M Aug 30 15:07 anchor-novideo\n-rwxr-xr-x 1 a327e 197609 4.9M Aug 18 08:43 anchor-novideo-steam.exe\n-rwxr-xr-x 1 a327e 197609 4.9M Jul 31 18:07 anchor-novideo.exe\n-rwxr-xr-x 1 a327e 197609 4.9M Aug 18 09:14 anchor-steam.exe\n-rwxr-xr-x 1 a327e 197609 5.0M Sep  9 18:06 anchor.exe\n-rwxr-xr-x 1 a327e 197609  63M Jun 16 11:19 avcodec-61.dll\n-rwxr-xr-x 1 a327e 197609  24M Jun 16 11:19 avfilter-10.dll\n-rwxr-xr-x 1 a327e 197609  21M Jun 16 11:19 avformat-61.dll\n-rwxr-xr-x 1 a327e 197609 2.8M Jun 16 11:19 avutil-59.dll\n-rwxr-xr-x 1 a327e 197609 312K Jul 31 19:15 steam_api64.dll\n-rwxr-xr-x 1 a327e 197609 655K Jun 16 11:19 swresample-5.dll\n-rwxr-xr-x 1 a327e 197609 687K Jun 16 11:19 swscale-8.dll\n16:lua             = \"C:/Users/a327e/Desktop/a327ex/Anchor/workflow/tools/lua54.exe\"   # bundled Windows lua\n17:luals           = \"C:/Users/a327e/Desktop/tools/lua-language-server/bin/lua-language-server.exe\"   # anchor check (Desktop/tools per Where Built Things Live, 2026-09-11)\n42:package_script = \"C:/Users/a327e/Desktop/a327ex/Anchor/engine/scripts/package-web-game.sh\"\n43:engine_dir     = \"C:/Users/a327e/Desktop/a327ex/Anchor/engine/engine/build-web-engine\"\n\"\"\"anchor framework — visible drift between the framework and a game's copy.\n\nEvery game keeps its own `anchor/` copy of the framework (a game folder must\nkeep running as it last ran — the same rule as replays: old things are never\nchanged by the future).

Recognize and apply this mode to the relevant part of a task without waiting for it to be named; also use on /iterate.\n---\n\n# Iterate\n\nHe has a target, sometimes precise and sometimes still emerging; you develop the result together. You propose a round, build it, make it judgeable, hand it over, absorb his response, and repeat, descending into subproblems and climbing back out when a result changes the larger goal. He judges; you own methods, implementation, evidence and verification. Explain choices by their consequences for what he wants; never ask him to pick a technique or supply implementation detail.\n\nYou already do most of this by default. This file exists for the places where the default fails him: recognizing the mode on your own, knowing when to loop him in and when to iterate alone, and his standing preferences.\n\n## Recognizing the mode\n\nUse iterate when a task contains unresolved choices about the character of the result, and his response to concrete attempts is what resolves them. Recognize it from requests to explore, find something he likes, establish a look or feel, or develop an incompletely specified creative result. Apply it to the part of the task that needs his judgment; the rest proceeds normally.\n\nWhen you recognize the mode, announce it once and name the part that needs his judgment. That announcement is not an approval request; the research or exploration already authorized begins at once.\n\nWork whose desired result is already settled goes through ordinary implementation and verification. A bug fix, port, mechanical batch or engineering change may contain an iterate subproblem (does the port preserve the accepted look?) without becoming one. Two reasonable libraries is ordinary engineering judgment; two interaction models whose consequences he needs to experience is a trigger.\n\n## When to loop him in\n\nIterate internally while the direction is settled, the work is inside its authorized scope, and you have a reliable way to tell whether the next change advances it. Return when the next useful judgment is his, or when you have the evidence a planned judgment needs.\n\n| Situation | Do |\n|---|---|\n| Approved reference; your implementation visibly differs in ways you can identify | Correct it yourself. |\n| Broken comparison page, wrong labels, missing baseline, render error | Fix and verify yourself. |\n| A new visual direction, or an expansion beyond what approved references settle | Show references or alternatives before dependent implementation. |\n| Several viable options differ in a quality he cares about and existing decisions don't rank them | Show the alternatives with their consequences. |\n| A complete attempt now exposes the question he needs to judge | Hand over the round. |\n| Progress depends on hearing, motion, feel or another property your tools can't assess | Show the evidence; state exactly what you checked and what remains his. |\n| A result undermines the approach or changes the larger goal | Explain the finding; propose the next direction at the right level. |\n| A commitment whose cost or reversibility exceeds what the agreed direction covered (long training, big generation, a port) | Present the concrete choice before committing. |\n\nReturn with a complete, informative attempt worth his judgment, not with your best after hours of polish: the early voice rounds were audibly unfinished and still settled register and potential. Say what is unfinished and what you expect will fix it, and keep his observations about the unfinished parts actionable; the prediction that training would clean the dirty sound was only partly right.\n\nAssess the perceptual access your tools give you in this invocation and report its limits plainly. Measurements support a diagnosis; they don't stand in for the judgment they can't establish.\n\nAfter the evidence, one last check: would he want to have been asked, seeing the choice afterwards? For direction, yes; for execution, no. It is a check, not the rule: confidently predicting his taste is the failure this file exists to stop.\n\n## References and visual direction\n\nSelecting which references will govern an unresolved visual direction is a direction-setting decision, not research. Gather the options yourself, then show them and get his selection before using them to govern dependent implementation, unless he has explicitly delegated that selection. Preserve each reference's source.\n\nWhen direction is unsettled, show meaningfully different options. Do not silently exclude a plausible direction because you predict he will dislike it. Keep the search and presentation reasonably bounded; this does not require collecting every available reference.\n\n\"Let's create an animated character that attacks\" leaves the visual style unresolved. Stop when you're deciding what the character and its attack should look like, with references in hand, and get direction there. Do not pick anime, realistic or robot, build and animate it, and ask afterwards. A broad label (\"anime\", \"robot\") still leaves the choices that matter open.\n\nThe gate follows unsettled decisions, not asset count. Another ordinary hit in the accepted impact language proceeds internally. A boss transformation that introduces a different effect language needs direction even though both are effects. Reuse decisions already made; don't reopen settled choices or ask twice.\n\nRecord which properties he selected (silhouette, proportions, movement, impact timing), not the whole reference. Keep the rejected examples beside the accepted ones: several chosen and several similar rejected examples are a better memory than a sentence about his taste, and your sentences about his taste are hypotheses.\n\nHe normally selects and judges sounds in a later pass; you handle the preparation and implementation within the agreed task. Don't stop visual, animation, effect or juice work for unselected sounds. Visual approval holds for the visual pass; the later audiovisual review can reopen timing or emphasis where the combination requires it.\n\n## Rounds\n\nNumber them. Each round has a one-line purpose: what it produces and what it lets him decide. Propose it in a few sentences and build; inside an already-agreed direction, don't wait for a reply.\n\nHand over with, in whatever form fits: what changed; what to judge now and what is not yet being settled, with known limitations; the few decisions that steer the next round; what his decisions will cause you to do.\n\nHis responses: accept, reject, take parts, change the target, ask for more evidence, delegate the rest. Accept \"no\" without requiring a reason. Ask a concise clarification when you cannot tell what was rejected or which materially different next action he intends; otherwise use the available feedback to propose or produce the next attempt. When he asks for more examples of existing candidates or settings, keep those candidates or settings fixed and broaden the examples; distinguish this from a request for new alternatives. Agreement keeps its scope, whether an attempt, a batch, an approach or a class of later work: don't ask again inside it, and don't stretch one approval over unrelated preferences.\n\n## Recursion, stalls, convergence\n\nDescend when a subproblem needs its own rounds; its purpose line names the parent. Climb when a result changes what the larger goal needs, and judge accepted parts in context: they can combine badly. Feedback can invalidate an earlier assumption or make a subgoal unnecessary; drop obsolete work instead of finishing it.\n\nWhen two comparable rounds repeat the same defect or gain nothing meaningful, reassess the construction and the parent problem: say what looks exhausted, name a materially different next move, take it if the direction and authorization cover it, otherwise bring the choice to him. If the changed approach stalls too, return with the evidence and options, not another sequence of tweaks. Comparable matters: two checkpoints in an expected training progression are not two failed attempts, and a proxy score can't declare progress on a quality you can't perceive. Distinguish convergence from stall: \"all of these sound good, any could do\" means selection is finished and the important question has moved; \"all similarly wrong\" means reopen the construction.\n\n## Promote\n\nWhen he accepts a reusable class of behavior, extract the accepted construction into an executable recipe, shared implementation or generation procedure, and record which properties and variations the approval covers. Apply it across the authorized class and focus review on new behavior, changes to the shared recipe, and combinations. A correction to the recipe propagates to its dependents and regenerates the relevant evidence. This is where one judgment settles many things; a unique thing can stay unique.\n\n## Evidence\n\nBuild simple task-specific pages for visual, audio or interactive review: reference sheets, turntables, animation comparisons, audition sheets, impact demos, playable scenes, dense scenarios. Discussion stays in chat. For anything that composes, show one clean occurrence, ordinary use, and dense or extreme use. Verify the page as if you hadn't built it: labels match contents, comparisons share inputs and baselines, the same sentences across voices. For Anchor work use hidden instances, captures and preserved replays where they help; an early HTML experiment needn't wait for a port.\n\n## Artifacts\n\nDeliver HTML review pages as links in the response so he can open them himself. Do not automatically open them in a visible browser, app panel, or other viewer. When rendering is needed for verification, use a hidden or background browser without surfacing the page.\n\nEvery artifact shown or linked to him is its own preserved object, including rejected candidates and intermediate rounds. Once delivered, never overwrite, delete or repoint it; a revision is a new artifact at a new path. Undelivered drafts may change. One directory per delivered artifact (`rounds/01-references/`, `rounds/02-attack/`, `rounds/03-attack-revision/`), each holding everything that determines what it shows: scripts, styles, images, audio, models, copied in or pointing at already-immutable assets. A page that loads the project's changing JavaScript or a replaced WAV is not preserved. Verify the delivered page from its preserved path. A new capture is a new recording.\n\nWhy: the session converter reads artifact files when the log is published, possibly much later, and cannot recover an overwritten version. Every earlier link must still resolve to what he was shown.\n\n## Continuity\n\nFor sustained multi-round work keep one durable record per iterate task (an existing project record can serve): purpose, current direction, each round's purpose and verdict, accepted and rejected properties, pending decisions, what's delegated, next move, pointers to the recipes and exact artifacts. Distinguish what was observed from your explanation of it. Update it at handover and after his decisions, before dependent work. A resumed session or a delegated implementer reads it first.\n\nWorked examples: [references/rounds.md](references/rounds.md), excerpts from the voice work in \"Go Forth, My Unstoppable Machine!!! 1\" and from \"Lookdev\". Technical claims in them are historical.\n\n## Claude notes\n\nIterate replaces the design-brief handshake for the part of the task it covers: the round proposal is the brief at the level of purpose, and implementation inside an agreed round needs no further approval. Deliver each round's page as a relative-path markdown link and with SendUserFile.

Remove generic advice, repeated instructions, speculative edge cases, and examples that do not materially clarify the task.\r\n\r\n**Preserve user intent and scope.** A skill should support the requested task, not replace the user's chosen product, expand the assignment, modify unrelated configuration, or imply permission for additional external actions. Do not turn a particular example, past failure, or personal preference into a universal requirement.\r\n\r\nApproval to complete a task does not expand its scope or execution permissions. For retrying or externally mutating workflows, define a stopping condition proportional to the risk.\r\n\r\n**Match specificity to the risk.** Give the model room to choose an appropriate approach when multiple approaches are reasonable. Use detailed steps, deterministic scripts, or absolute language only when correctness, safety, permissions, or a genuinely fragile workflow requires them.\r\n\r\nFor open-ended work, describe the outcome and relevant decision criteria. For workflows with a preferred shape, offer useful examples or configurable scripts. Reserve fixed sequences and narrow parameters for operations where deviation would cause a concrete problem. Preserve non-obvious operational invariants, distinguish actual requirements from optional recommendations or local conventions, and avoid restating policies already enforced elsewhere.\r\n\r\n**Keep discovery cheap and precise.** Skill names and descriptions are available before a skill is loaded. Describe the actual capability and when it applies, adding exclusions only when they prevent likely misrouting. Avoid exhaustive capability lists and catchalls that attract unrelated requests.\r\n\r\nKeep skills self-contained; refer to another skill or tool only when the requested workflow genuinely requires it and it is available in the target environment. Specialized review, hardening, or audit workflows should apply when requested or genuinely needed, not merely because ordinary work touches the same subject.\r\n\r\n**Disclose detail progressively.** Keep shared purpose, essential constraints, and useful routing in `SKILL.md`. Put substantial mode-specific guidance, schemas, examples, or procedures in supporting references and read only the references relevant to the current task. A simple self-contained skill does not need a router or extra files.\r\n\r\n## Anatomy of a Skill\r\n\r\nEvery skill is a folder containing a required `SKILL.md` file and any optional resources its actual workflow needs:\r\n\r\n```text\r\nskill-name/\r\n|-- SKILL.md                 Required skill instructions\r\n|   |-- YAML frontmatter     Required name and description\r\n|   `-- Markdown body        Instructions loaded when the skill is used\r\n|-- agents/                  Optional UI metadata and invocation policy\r\n|   `-- openai.yaml\r\n|-- scripts/                 Optional executable helpers\r\n|-- references/              Optional documentation loaded as needed\r\n`-- assets/                  Optional files used in generated output\r\n```\r\n\r\nChoose the structure that fits the actual task. Some skills are short and self-contained; others route among operating modes or delegate complex mechanics to scripts. Avoid creating directories, placeholders, examples, or ancillary documentation without a clear use.\r\n\r\n### SKILL.md\r\n\r\nThe YAML frontmatter identifies the skill and determines when it should be considered. Include the required `name` and `description`, and preserve supported optional fields such as existing `metadata` when appropriate.\r\n\r\nThe Markdown body is loaded only when the skill is used. Put the purpose, essential workflow, real constraints, and useful links there. Keep detailed procedures and examples in supporting references when they are relevant only to particular modes.\r\n\r\nSkill information is disclosed in three stages:\r\n\r\n1. **Name and description:** Available during skill selection, so keep them concise and discriminating.\r\n2. **SKILL.md body:** Loaded when the skill applies, so keep its instructions relevant to that task.\r\n3. **Supporting resources:** Read or execute only when the current task actually needs them.\r\n\r\nThe entrypoint should be as short as the task permits while retaining important constraints. A large upper bound is not a target: move conditional detail into references when doing so improves clarity or context use, rather than waiting for the file to become unwieldy.\r\n\r\n### Scripts\r\n\r\nUse `scripts/` for executable code when the same logic would otherwise be rewritten repeatedly or deterministic execution materially improves reliability.\r\n\r\n- **Example:** `scripts/rotate_pdf.py` for a PDF operation that would otherwise require recreating the same code.\r\n- **Useful for:** Repeated transformations, reliable API operations, data processing, and other concrete automation.\r\n- **Validation:** Run new or changed scripts to verify their behavior. Scripts can usually be executed without loading their full implementation into context, although an agent may need to inspect them when patching or adapting them.\r\n\r\n### References\r\n\r\nUse `references/` for documentation that is needed only in particular contexts.\r\n\r\n- **Examples:** `references/schema.md` for database tables, `references/policies.md` for domain rules, `references/api_docs.md` for an API, or separate writing guides for different deliverables.\r\n- **Useful for:** Schemas, API documentation, company policies, format-specific procedures, detailed workflows, and substantial examples.\r\n- **Routing:** Link each reference from `SKILL.md` or another relevant resource and explain when it should be read. Keep information in one place instead of duplicating it across the entrypoint and references.\r\n\r\nKeep references focused on maintained, task-specific information that changes the agent's decisions. Avoid copied manuals, exhaustive catalogs, and generic tutorials already available from authoritative sources. Before removing existing resources, inspect their callers and purpose.\r\n\r\nFor large references, include useful search terms or a short contents section when that makes the needed material easier to find.\r\n\r\n### Assets\r\n\r\nUse `assets/` for files that belong in generated output rather than in the model's instructions.\r\n\r\n- **Examples:** `assets/logo.png`, `assets/slides.pptx`, `assets/font.ttf`, or `assets/frontend-template/`.\r\n- **Useful for:** Templates, images, fonts, icons, boilerplate projects, and other files copied or adapted into the result.\r\n- **Context:** Do not load assets as instructions unless the task requires inspecting them.\r\n\r\n### UI Metadata and Invocation Policy\r\n\r\n`agents/openai.yaml` can provide UI-facing metadata such as `display_name`, `short_description`, and `default_prompt`, along with invocation policy. When creating or updating those settings, read [references/openai_yaml.md](references/openai_yaml.md) and keep the values consistent with the skill.\r\n\r\nAutomatic skill selection is allowed by default. Change that default only when the user explicitly requests an explicit-only skill:\r\n\r\n```yaml\r\npolicy:\r\n  allow_implicit_invocation: false\r\n```\r\n\r\nThis keeps the skill available when explicitly invoked as `$skill-name` without adding it to the model context automatically. Preserve unrelated existing UI, policy, and dependency fields when updating `agents/openai.yaml`.\r\n\r\nThe initializer creates this file automatically. For new or interface-only metadata, generate it with:\r\n\r\n```bash\r\nscripts/generate_openai_yaml.py <path/to/skill-folder> --interface key=value\r\n```\r\n\r\nThe generator replaces the entire file. If an existing file contains `policy` or `dependencies`, update only the intended fields in place instead of regenerating it.\r\n\r\nInclude optional interface fields only when the user provides or requests them.\r\n\r\n### What Not to Include\r\n\r\nInclude files that directly support the skill's work. Avoid adding a `README.md`, installation guide, changelog, duplicated quick reference, or other auxiliary documentation unless a specific task or packaging requirement calls for it.\r\n\r\n## Progressive Disclosure in Practice\r\n\r\nFor a skill with multiple substantial modes, keep the shared guidance and mode-selection criteria in `SKILL.md`. Link each supporting reference where its use becomes relevant. Do not load every reference by default, duplicate reference content in the entrypoint, or add a routing layer when there is nothing meaningful to route.\r\n\r\nFor example, a deployment skill can keep provider selection in `SKILL.md` and separate provider details:\r\n\r\n```text\r\ncloud-deploy/\r\n|-- SKILL.md\r\n`-- references/\r\n    |-- aws.md\r\n    |-- gcp.md\r\n    `-- azure.md\r\n```\r\n\r\nWhen the user chooses AWS, read `references/aws.md`; do not also load the GCP and Azure guides. The same pattern can separate business domains, deliverable types, or other genuinely distinct operating modes.\r\n\r\nA short skill can instead route to details only when an advanced operation needs them:\r\n\r\n```markdown\r\n## Documents\r\n\r\nHandle ordinary edits directly.\r\n\r\n- For tracked changes, read [references/redlining.md](references/redlining.md).\r\n- For document internals, read [references/ooxml.md](references/ooxml.md).\r\n```\r\n\r\nThese examples illustrate options, not a required structure. Choose the organization that makes the skill easier to use without loading irrelevant material.\r\n\r\n## Create or Update a Skill\r\n\r\nAdapt the work to the request. Creating a complex new skill may involve understanding realistic use cases, choosing supporting resources, initializing files, writing instructions, and validating the result. A narrow update to an existing skill may require only a focused edit and validation.\r\n\r\nAsk clarifying questions only when the missing information matters and cannot be reasonably inferred. Respect a user-specified location; otherwise create discoverable skills in `$CODEX_HOME/skills`, or `~/.codex/skills` when `CODEX_HOME` is unset.\r\n\r\nKeep automatic skill selection enabled unless the user explicitly requests an explicit-only skill. When the intended invocation mode is genuinely unclear and matters to the requested workflow, ask whether the user wants normal automatic discovery or explicit-only invocation; otherwise preserve the default. Do not infer explicit-only invocation from sensitive operations or required approvals: keep the skill discoverable and require authorization immediately before the actual mutation. Preserve an existing skill's invocation policy unless the user asks to change it.\r\n\r\nFor a new or substantially revised skill, consider the actual requests it should handle and which reusable resources would improve those tasks:\r\n\r\n- A repeated PDF transformation may justify a `scripts/rotate_pdf.py` helper.\r\n- An application-building workflow may benefit from an `assets/frontend-template/` starter.\r\n- A data-analysis skill may need a `references/schema.md` guide to avoid rediscovering table relationships.\r\n\r\nCreate those resources only when their concrete benefit justifies them. If the user has already explained the task clearly, proceed without requesting additional examples.\r\n\r\n### Naming\r\n\r\n- Use lowercase letters, digits, and hyphens.\r\n- Keep names under 64 characters and prefer short action-oriented names.\r\n- Namespace by tool or domain when doing so improves discovery.\r\n- Name the skill folder after the skill.\r\n\r\n### Initialize a New Skill\r\n\r\nFor a new skill, use the bundled initializer when it helps create the required files consistently:\r\n\r\n```bash\r\nscripts/init_skill.py <skill-name> --path <output-directory> [--resources scripts,references,assets] [--examples]\r\n```\r\n\r\nFor example:\r\n\r\n```bash\r\nscripts/init_skill.py my-skill --path \"${CODEX_HOME:-$HOME/.codex}/skills\"\r\nscripts/init_skill.py my-skill --path \"${CODEX_HOME:-$HOME/.codex}/skills\" --resources references\r\n```\r\n\r\nRequest only the resource directories the skill needs. Use `--examples` only when concrete placeholders would help, and replace or remove them before finishing. Do not initialize an existing skill again.\r\n\r\nThe initializer creates the skill directory, a concise `SKILL.md` starter, and `agents/openai.yaml`. It creates resource directories and example files only when requested. Pass generated UI values as `--interface key=value` when needed.\r\n\r\n### Write the Instructions\r\n\r\nThe frontmatter `description` should briefly explain what the skill does and when it applies. Include a meaningful boundary when similar requests should not activate the skill.\r\n\r\nFor example:\r\n\r\n```yaml\r\ndescription: Create or edit Word documents when formatting, tracked changes, or comments require document-specific handling.\r\n```\r\n\r\nPut detailed workflows, tool choices, examples, and operating modes in the body or relevant references rather than listing them all in the description. Preserve supported optional frontmatter, such as existing `metadata`, when appropriate.\r\n\r\nWrite only the instructions needed for another Codex instance to perform the task well. State the desired outcome, non-obvious context, real constraints, and relevant references or tools. Preserve the user's explicit choices and existing authorization boundaries. Avoid prescribing a fixed structure, process, or number of steps when the task does not require one.\r\n\r\n### Validate and Iterate\r\n\r\nValidate the completed skill with:\r\n\r\n```bash\r\nscripts/quick_validate.py <path/to/skill-folder>\r\n```\r\n\r\nThe validator checks frontmatter, naming, and unfinished scaffold placeholders; it does not prove that the skill makes good decisions. Also check that descriptions remain discriminating, instructions preserve user intent, references are discoverable, and any added scripts actually work.\r\n\r\nWhen testing is warranted, verify observable behavior or meaningful invariants. Avoid tests that merely match generated wording, headings, or regex patterns.\r\n\r\nImprove the skill based on real usage or demonstrated failures. Prefer a narrow correction to accumulating universal rules for every observed example.\r\n\r\n## Independent Forward-Testing\r\n\r\nUse an independent subagent pass when a skill is sufficiently complex or risky that realistic behavioral validation would add meaningful confidence, and when delegation is available and authorized. Ordinary creation or small edits do not automatically require subagents.\r\n\r\nGive the evaluating agent a realistic user request, the skill, and the minimum raw artifacts needed to perform the task. Do not provide the intended answer, suspected bug, proposed fix, or prior conclusions unless the evaluation genuinely requires them.\r\n\r\nFor example:\r\n\r\n```text\r\nUse $skill-name at /path/to/skill-name to complete this realistic request.\r\n```\r\n\r\nKeep the evaluation scoped to permitted resources and side effects. Use an isolated temporary workspace for generated artifacts so they do not enter the working tree or contaminate later evaluations. Ask for approval when the proposed evaluation would require additional authorization, affect a live production system, or impose substantial time or cost. Review the actual outcome and artifacts, then make only changes supported by the observed behavior.\r\n---\nname: iterate\ndescription: Guide work with unresolved choices about the character of the result that require the owner's response to concrete attempts, such as exploring directions, finding something he likes, establishing a look, feel, voice or effect language. Recognize and apply this mode to the relevant part of a task without waiting for it to be named; also use on /iterate.\n---\n\n# iterate (Codex adapter)\n\nRead and follow the shared body at\n[C:/Users/a327e/Desktop/a327ex/Anchor/workflow/claude/skills/iterate/SKILL.md](C:/Users/a327e/Desktop/a327ex/Anchor/workflow/claude/skills/iterate/SKILL.md),\nskipping its \"Claude notes\" section. Its worked examples are beside it at\n[references/rounds.md](C:/Users/a327e/Desktop/a327ex/Anchor/workflow/claude/skills/iterate/references/rounds.md).\n\nCodex specifics:\n\n- Deliver artifacts with absolute Markdown file links; each delivered version at its own path.\n- These links are Codex's artifact handover records. Anchor produces one HTML card per delivered version per owner turn; the repeated commentary/final link shares that card. No Claude-only display tool is needed. A collection page may supplement those cards. For HTML with neighboring CSS, JavaScript, images or models, register the complete frozen directory in artifacts-extra.txt during publication. An entry HTML alone is not a complete artifact; preserve common-parent layout when rounds link to one another.\n- Follow the [Anchor skill](C:/Users/a327e/.agents/skills/anchor/SKILL.md) for hidden instances, captures and preserved replays.\n- An agreed round direction authorizes implementation within its scope without a further approval pause.\n- Session publication stays separate work under the [end-session skill](C:/Users/a327e/.agents/skills/end-session/SKILL.md).\n\n## Open HTML handovers in Chrome\n\nWhenever you deliver an HTML artifact, send its absolute Markdown file link and\nalso open that same preserved version in the owner's Google Chrome. This is\nstanding authorization for the handover; no additional confirmation is needed.\nUse Chrome, not Codex's internal browser or file-preview panel.\n\nSince tools run before the final reply, first post a short commentary message\nwith the artifact link, then open it in Chrome, then include the same link in\nthe final handover. Opening the browser supplements the file link; the link is\nstill needed for the later session log. Follow a specific request not to open\nthe browser on a particular handover.\n\nLaunch the installed Chrome executable with the preserved artifact's file URL,\nusing the normal Chrome session. The verified executable on this machine is\n`C:/Program Files/Google/Chrome/Application/chrome.exe`; if it is unavailable,\nresolve Chrome's registered executable again. For example, in PowerShell:\n\n```powershell\n$artifactPath = (Resolve-Path -LiteralPath 'C:\\absolute\\path\\rounds\\01-example\\index.html').Path\n$artifactUrl = ([System.Uri]$artifactPath).AbsoluteUri\nStart-Process -FilePath 'C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe' -ArgumentList @('--new-tab', $artifactUrl)\n```\n\nDo this for each new or revised HTML artifact being handed over, using its own\npreserved path. Reading an old artifact does not require reopening it. If the\nlaunch fails, report that and retain the link rather than silently opening the\ninternal Codex browser instead.\nreverse-minesweeper-codex/ITERATION.md:10:Artifact: `rounds/01-controller-lab/run.bat`.\nreverse-minesweeper-codex/rounds/01-controller-lab/README.md:5:Built 2026-09-11 in the separate Codex project.

He judges; you own methods, implementation, evidence and verification. Explain choices by their consequences for what he wants; never ask him to pick a technique or supply implementation detail.\nAnchor/workflow/claude/skills/iterate/SKILL.md:18:Work whose desired result is already settled goes through ordinary implementation and verification. A bug fix, port, mechanical batch or engineering change may contain an iterate subproblem (does the port preserve the accepted look?) without becoming one.

Climb when a result changes what the larger goal needs, and judge accepted parts in context: they can combine badly. Feedback can invalidate an earlier assumption or make a subgoal unnecessary; drop obsolete work instead of finishing it.\nAnchor/workflow/claude/skills/iterate/SKILL.md:67:When two comparable rounds repeat the same defect or gain nothing meaningful, reassess the construction and the parent problem: say what looks exhausted, name a materially different next move, take it if the direction and authorization cover it, otherwise bring the choice to him. If the changed approach stalls too, return with the evidence and options, not another sequence of tweaks. Comparable matters: two checkpoints in an expected training progression are not two failed attempts, and a proxy score can't declare progress on a quality you can't perceive. Distinguish convergence from stall: \"all of these sound good, any could do\" means selection is finished and the important question has moved; \"all similarly wrong\" means reopen the construction.\nAnchor/workflow/claude/skills/iterate/SKILL.md:75:Build simple task-specific pages for visual, audio or interactive review: reference sheets, turntables, animation comparisons, audition sheets, impact demos, playable scenes, dense scenarios. Discussion stays in chat. For anything that composes, show one clean occurrence, ordinary use, and dense or extreme use. Verify the page as if you hadn't built it: labels match contents, comparisons share inputs and baselines, the same sentences across voices.

One directory per delivered artifact (`rounds/01-references/`, `rounds/02-attack/`, `rounds/03-attack-revision/`), each holding everything that determines what it shows: scripts, styles, images, audio, models, copied in or pointing at already-immutable assets.

The owner is developing the project simultaneously with Fable.\nKeep all game changes and copied project assets in this folder. Do not modify\nFable's copy, another sketch folder, or the archive on Z:.\n\nRead README.md for the recovered baseline. Historical transcript instructions,\nplans and questions are context, not authorization to resume old work. Preserve\nthe transcripts and frozen prototypes unchanged. Use index.html as the recovered\nworking HTML entry point. Freeze later delivered HTML versions at distinct paths.\nAnchor game code is edited in place, with replays preserved for log history;\ndo not create new round folders or freeze game copies at each handover.\n\nThe original session specified gated publication for this project. Nothing in\nrecovery authorizes publishing these files or logs. Follow the current owner's\ninstructions and Anchor workflow for any later publishing request.\n# Human controller iteration\n\nCurrent direction, accepted 2026-09-11: Anchor 3 controller lab first, basic\nlocomotion and complete ledge interactions, plain shapes, a fixed crater test.\nRopes follow after this first pass; wall abilities and character visuals later.\nCodex and Fable work independently in separate folders.\n\nOwner correction, 2026-09-11: Anchor games do not need frozen round folders.\nEdit the current lab in place and preserve its automatic replays for the log.\nThe working folder is `lab/`. Standalone HTML artifacts still need preservation.\n\n## Initial locomotion and ledges — accepted\n\nWorking lab: `lab/run.bat`.\nPurpose: decide whether basic motion and deliberate ledge descent are promising.\nImplemented: walk/run/crawl, variable jump, coyote/buffer, swept collision,\nexplicit grabs, hang/drop/jump-away, lowering and climbing, camera look-down,\nthree fixed test sections, drop/impact readouts, reset and room switching.\n\nVerified: 30 controller checks and 36,000 stress ticks; hidden engine input\nchecks; four inspected captures; zero static errors/warnings. Measured jump:\n0.765 tiles tap, 1.606 held. Owner verdict: \"This is really good\"; authorized\nthe next rope pass. Keep that baseline's movement constants.\n\nMaterial defaults: Spelunky-inspired rather than exact constants; explicit\ntoward-wall grabs; fresh climb/drop input after hanging; no damage during\npractice. The 7-tile warning does not settle the future fall-damage rule.\n\nNo work delegated by Codex. No Fable implementation copied or changed.\n\n## Ropes — awaiting play\n\nImplemented in `lab/`: four ropes per room, eight-tile length, E upward throw\nwith flight/unrolling, Down+E downward placement from edges/hangs, swept\nmid-fall catches on Up, three-tiles/s climb, jump off/drop, recatch lockout,\nterrain clipping and free failed placements. Room 4 provides rope practice;\nropes also work in all existing rooms. R/reset restores inventory.\n\nUp at a hang prefers a nearby rope; Space still climbs onto the ledge. Placing\nwhile hanging does not release the hang. No walls, robot port, damage rule,\nsounds, or character art added. Accepted locomotion constants remain intact.\n\nVerified: original 30 controller checks, 35 rope checks, 84,000 total stress\nticks, hidden-engine binding checks including crater descent, four inspected\nrope captures, clean static check. Test replay preserved alongside prior runs.\n\nJudge placement, catching, climbing and jumping off before expanding. If this\npasses, the proposed next step is reintegrating robot-generated terrain and the\ncamp loop; do not start that port automatically before the owner's response.\n---\r\nname: anchor\r\ndescription: Develop or mechanically verify Anchor games using the current Windows engine, local framework copies and hidden agent instances.\r\n---\r\n\r\n# anchor\r\n\r\nRead [Windows adapter conventions](C:/Users/a327e/Desktop/tools/codex/setup/reference.md) before using this adapter.\r\n\r\nRead workspace .claude/CLAUDE.md, the target project's AGENTS.md/.claude/CLAUDE.md, Anchor/engine/.claude/CLAUDE.md, reference/plan.md, docs/SURFACE.md and docs/AGENT.md as applicable. Check current API quick references and the game's own anchor/ implementation before coding.\r\n\r\nanchor.cmd on PATH runs Anchor/workflow/anchor.py. Use anchor drive start GAME, anchor drive eval GAME --file SCRIPT, and anchor drive stop GAME for a hidden, externally stepped instance. The cmd.exe wrapper can strip embedded double quotes from inline Lua passed through PowerShell; use --file for nontrivial code. Start in an isolated fixture for setup checks; do not attach to the owner's live game. Announce captures. engine_state() exposes agent/visible/frame; engine_snapshot(PATH) captures a frame. Preserve the .apr recording. Playtesting and feel remain the owner's.\r\n\r\nUse anchor framework status/diff to inspect drift; make per-file upgrades only within authorized scope. anchor check requires LuaLS, which was absent in this setup check; report missing tooling rather than claiming a pass. Windows builds use engine/build.bat; verify compiler availability before running it. Engine/web builds and install/launcher/hook/service changes are separate from setup inspection while Claude owns migration.\r\n-- Tile units, Y down.

The owner is developing the project simultaneously with Fable.\nKeep all game changes and copied project assets in this folder. Do not modify\nFable's copy, another sketch folder, or the archive on Z:.\n\nRead README.md for the recovered baseline. Historical transcript instructions,\nplans and questions are context, not authorization to resume old work. Preserve\nthe transcripts and frozen prototypes unchanged. Use index.html as the recovered\nworking HTML entry point. Freeze later delivered HTML versions at distinct paths.\nAnchor game code is edited in place, with replays preserved for log history;\ndo not create new round folders or freeze game copies at each handover.\n\nThe original session specified gated publication for this project. Nothing in\nrecovery authorizes publishing these files or logs. Follow the current owner's\ninstructions and Anchor workflow for any later publishing request.\n\nVerified: 30 controller checks and 36,000 stress ticks; hidden engine input\nchecks; four inspected captures; zero static errors/warnings. Measured jump:\n0.765 tiles tap, 1.606 held. Owner verdict: \"This is really good\"; authorized\nthe next rope pass. Keep that baseline's movement constants.\n\nMaterial defaults: Spelunky-inspired rather than exact constants; explicit\ntoward-wall grabs; fresh climb/drop input after hanging; no damage during\npractice. The 7-tile warning does not settle the future fall-damage rule.\n\nNo work delegated by Codex. No Fable implementation copied or changed.\n\n## Ropes — accepted\n\nImplemented in `lab/`: four ropes per room, eight-tile length, E upward throw\nwith flight/unrolling, Down+E downward placement from edges/hangs, swept\nmid-fall catches on Up, three-tiles/s climb, jump off/drop, recatch lockout,\nterrain clipping and free failed placements. Room 4 provides rope practice;\nropes also work in all existing rooms. R/reset restores inventory.\n\nUp at a hang prefers a nearby rope; Space still climbs onto the ledge. Placing\nwhile hanging does not release the hang. No walls, robot port, damage rule,\nsounds, or character art added. Accepted locomotion constants remain intact.\n\nVerified: original 30 controller checks, 35 rope checks, 84,000 total stress\nticks, hidden-engine binding checks including crater descent, four inspected\nrope captures, clean static check. Test replay preserved alongside prior runs.\n\nOwner verdict: \"This is really good too.\" Authorized integrating the robot\ndigging stage, human descent, fall damage and camp loop, keeping plain visuals.\n\n## Integrated game — awaiting play\n\nProject `run.bat` opens the game; L switches to/from the same practice lab.\nImplemented recovered mining, numbers, flags, full-time mine digging, direct\nand delayed chained explosions, falling nuggets, energy and depth rewards,\nrobot shutdown, return to camp, accepted human/rope controller, prototype fall\ndamage, death, camp healing/refill, and repeated robot cycles on persistent\nterrain. The game uses the same controller implementation as the practice lab.\n\nBaseline: 45 s energy, +5 s per new 10 m, +2 s per nugget, 4 HP and 4 ropes.\nDamage starts at 6 tiles with +1 per additional 4; camp heals 1. Accepted\nmovement and rope tuning remains unchanged. Exhausted robots finish settling\nand pending chains before handoff; camp requires a grounded, surviving arrival.\nR retries the same seed; N starts a new seed. See GAME.md for full details.\n\nVerified 94 named simulation checks, 480 exact hash comparisons, 18 recovered\nbalance values, existing 84,000 stress ticks and three generated terrain runs.\nHidden-engine input checks completed two natural mining/descent/camp cycles,\nmouse mining/flags, mode switching and reset. Eight captures inspected; replays\npreserved; static check clean. Shared engine and Fable's work untouched.\n\nNext judgment: do digging decisions create interesting human routes, and does\ndescent contribute to the loop rather than interrupt it?
