1    Title: Anchor App Phase 1 Part 3
2   Date: 2026-05-11 12:39:03
3   
4   # Anchor App Phase 1 Part 3
5   
6   ## Summary
7   
8   Phase 1 Part 3 of the Anchor App: shipped embedded views (step 8), the view clipboard (step 9), recursive input routing through embeds, an indirect-cycle render guard, cross-pane click-outside-deselect, and a visible pane-focus border. Phase 1 foundation now complete except for text editing (deferred to Part 4 / focused-plan Phase A). Also refocused the long-term plan to a two-feature scope (writing + website) in a new `plan_focused.md` and marked the original `plan.md` "on hold."
9   
10  **Session orientation:**
11  - Read the prior session log (`a327ex-site/logs/anchor-app-phase-1-part-2.md`, 6600 lines) head + relevant sections. The summary at the top confirmed Phase 1 Part 2 ended at the natural pause BEFORE step 8 (embedded views) and Phase 1 Part 3 (text editing).
12  - Read `plan.md`, `docs/ui_architecture.md`, current `canvas.lua`, `main.lua`, `workspace.lua`, `pane.lua`, `model.lua` to ground the state.
13  - Read `a327ex-site/README.md` to understand the website's current Lua-server + markdown pipeline.
14  
15  **Plan refocus to writing + website:**
16  - User wanted to scope the app down to two priority features (a story they want to write + a327ex.com maintenance) and discard the filesystem / code editor / music / game-dev / knowledge / background-processing phases from the original 10-phase plan.
17  - Used `AskUserQuestion` to surface four architectural questions: format (native vs markdown export), story shape (prose vs interactive), milestone target, and what to do with the canvas work already shipped.
18  - User chose: **native format all the way** ("the entire website will be Anchor App views, essentially" — WASM-rendered, no markdown export step); **mostly plain prose**; **writing → website order**; **keep canvas architecture, create new plan file**.
19  - Created `Anchor2/app/plan_focused.md` with four sequential phases: Phase A (text element + editing), Phase B (writing mode + multi-document), Phase C (publishing: WASM viewer + server), Phase D (story-shaped polish).
20  - Added a one-paragraph "ON HOLD" banner at the top of `plan.md` pointing to `plan_focused.md`. Did NOT delete or modify the original plan content per user instruction.
21  
22  **Confirming step 8 hadn't actually started:**
23  - User claimed step 8 was "partly working" from the previous session. Pushed back honestly because the log's closing exchange was "Let's pause here" right after the step-8 explanation, and grepping `embedded_view` / `embed_view` / `inner_pane` across the codebase returned zero matches in any source file (only `plan.md` + `docs/ui_architecture.md` mentions).
24  - User confirmed they were misremembering — what they had was step 7 (multi-view of one model). Step 8 implementation started fresh.
25  
26  **Step 8 — embedded views (panes as canvas elements):**
27  - New element kind `{type='embedded_view', pane_id, pane_type, model_id, pane, x, y, w, h}` alongside existing `image` element.
28  - `main.lua`: changed `canvas_b` from `model_id='canvas:scratch'` to `model_id='canvas:host'` so split mode has two distinct models and can host an embed of canvas:scratch in canvas:host. Both still share the canvas pane type.
29  - `save_canvas` extended with embedded_view serialization (writes `pane_id`, `pane_type`, `model_id`, `x/y/w/h`).
30  - `read_canvas_elements` extended with embedded_view branch using idempotent pane creation: `panes[sav.pane_id]` is reused if already registered, otherwise `pane({id, type, model_id})` is created fresh. The inner pane's init runs `canvas_model_load(model_id)` which is itself idempotent (returns existing or creates new).
... [50 more lines]

80   - User feedback: "Currently ctrl+shift+C copies the original after you clicked it, but there's no visual feedback that it's selected. I think that's important."
81  - `pane.lua`: `pane:update` now caches `self._rect = rect` before dispatching to the type's update. Lets external code find any pane's last-drawn rect (slot rect for top-level panes, embed window-rect for inner panes).
82  - `workspace.lua`: new `paint_focus_border()` paints a 1px lavender border around `panes[pane_focus_id]._rect`. Called after pane updates so inner embed panes have their rect cached (they update during their host's render branch, deep in the frame). Drawn in window coords without re-establishing parent stencil — accepted V1 limitation (border on an embed extending past its host's slot will draw past the slot boundary).
83  - Updated Ctrl+Shift+C logic: if focused pane is a canvas with a `selected_el` of type `embedded_view`, capture the embed's `(type, model_id, w, h)` instead of the host pane. Marked with `kind='embed'`. Otherwise capture the pane (marked `kind='pane'`).
84  - Updated paste: uses captured `w`/`h` when present (preserves embed dimensions), falls back to 400×300 for pane captures.
85  
86  **One-thing-selected rule (last visual refinement):**
87  - User feedback: "Only one thing should be selected at a time by default, so if we click an image inside the embed, we want only the image visible as selected. The embed, the pane the embed are in should not be visually showing as selected."
88  - Fix: in `paint_focus_border`, added `if p.selected_el then return end` so the focus border is suppressed when the focused pane has a more specific selection (its element's own chrome already signals focus).
89  - Result: clicking an image inside an embed shows ONLY the image's selection chrome — no focus border on the embed, no focus border on the slot. Alt+click on embed shows only the embed's handle chrome — no focus border on the slot. Clicking empty area in a pane shows the focus border (no element competes).
90  
91  **Mode-scoped keybindings memory:**
92  - User noted: "later when we're actually using the app live we'll want to add modes and so on, because we'll not be doing embed view copies or switching panes around that often, so specific modes to capture those hotkeys so they don't collide with more natural usage makes sense."
93  - Saved a feedback-type memory at `~/.claude/projects/E--a327ex/memory/feedback_anchor_app_mode_scoped_keybinds.md` explaining the partitioning principle (structural commands stay workspace-global, in-mode commands shadow them) and added an entry to MEMORY.md under "Anchor App (Omega App)."
94  
95  **Files modified this session:**
96  - `Anchor2/app/panes/canvas.lua` — embedded_view element type, find_pointer_target callback, owns_pointer gating, cycle guard, click-outside-deselect, canvas_spawn_embedded_view helper, stub-first canvas_model_load
97  - `Anchor2/app/workspace.lua` — pointer target resolution, pane_owns_pointer, recursive route_drops, focus-on-deepest-pane, view clipboard handler, paint_focus_border, cursor baseline
98  - `Anchor2/app/pane.lua` — find_pointer_target dispatch, _rect caching
99  - `Anchor2/app/main.lua` — canvas_b → canvas:host
100 - `Anchor2/app/docs/ui_architecture.md` — TL;DR updated for Phase 1 Part 3 (embedded views, view clipboard, recursive routing, cycle guard, click-outside-deselect, visible focus)
101 - `Anchor2/app/plan.md` — added "ON HOLD" banner, updated Current Status date to 2026-05-11, updated foundation status table, replaced "What's next" with Phase 1 Part 3 changelog + Phase 1 Part 4 forward look
102 - `Anchor2/app/plan_focused.md` — created (new active plan, writing + website scope); updated to mark steps 8 and 9 as shipped
103 - `~/.claude/projects/E--a327ex/memory/MEMORY.md` — added pointer to new feedback memory
104 - `~/.claude/projects/E--a327ex/memory/feedback_anchor_app_mode_scoped_keybinds.md` — new feedback memory

108 > Let's continue on the Anchor App. Last session was Anchor App Phase 1 Part 2 and you can read the summary to get oriented, as well as general documents in Anchor2/app. This session we'll continue with phase 1, but first I want to redo the entire plan a little. The entire plan contains various features for code, filesystem and other things that are not priority right now. I have a story I want to write, and the website (a327ex-site) I want to maintain, so I'd like to focus the app on those two features first: writing + website. This corresponds to two phases of the many that the plan contains. We can discard the others for now (filesystem, coding, everything else).

1    # Anchor App — Focused Plan: Writing + Website
2   
3   *Active plan as of 2026-05-11. The full 10-phase vision in [`plan.md`](plan.md) is on hold; this file scopes current development to two priority features.*
4   
5   ---
6   
7   ## Why this exists
8   
9   The long-term plan in `plan.md` is the omega-app vision: a single environment for writing, code, music, games, knowledge, agents. That's still the destination, but right now there are two things that actually need to ship before anything else:
10  
11  1. **Writing.** A story I want to write. Mostly plain prose, the occasional image.
12  2. **Website.** a327ex.com is currently a self-hosted Lua + markdown pipeline (see `a327ex-site/README.md`). The endgame is for the entire site to be Anchor App views rendered by the engine compiled to WASM — no markdown export step, no source-vs-rendered split. The canvas I wrote in the app IS what gets served to visitors.
13  
14  Everything else (filesystem/tagging, code editor, music views, game-dev views, knowledge graph, background processing, the full multi-agent roster) is parked. Resume from `plan.md` once these two land.
15  
16  ---
17  
18  ## If you're a future session picking this up
19  
20  Read, in this order:
21  
22  1. **This file** — for the focused scope and phase plan.
23  2. **`plan.md`** — for the long-term vision, architecture decisions, and `## Current Status` ledger of what's already shipped. Most of the architecture sections still apply unchanged.
24  3. **`docs/ui_architecture.md`** — UI system architecture (workspace/panes/slots, model–view, hosts, RectCut). Load-bearing and non-obvious from the codebase.
25  4. **`docs/visual_identity.md`** — palette, typography, density, chrome.
26  5. **`docs/mockup_v2_ui_kit.html`** + **`docs/mockup_v2_write.html`** — authoritative visual reference for primitives and writing mode.
27  6. **`Anchor2/.claude/CLAUDE.md`** — framework-v2 coding disciplines.

2     canvas — free-flowing element canvas pane.
3   
4     Drops: image files dropped on the canvas are saved to the content
5     store and added as elements at the cursor position, native pixel
6     size. Oversize images overflow the slot intentionally; the stencil
7     clip below hides anything outside the canvas rect, so overflow
8     doesn't bleed into neighboring panes.
9   
10    Element shapes (in self.elements):
11      {type='image',         blob_id='blob:<hex>.<ext>', image=<image>, x=, y=, w=, h=}
12      {type='embedded_view', pane_id=<string>, pane_type=<string>,
13                             model_id=<string>, pane=<pane instance>, x=, y=, w=, h=}
14  
15    Image elements: blob_id is the persisted reference. `image` is the
16    live texture handle, re-resolved from blob_id on load. x/y are top-
17    left in canvas-local coordinates. w/h are the rendered size, starting
18    at native image dims and changing as the user resizes.
19  
20    Embedded-view elements (step 8): a *pane* hosted as a canvas element.
21    pane_id is the auto-generated stable id under which the inner pane is
22    registered in `panes`. pane_type + model_id are the type + backing
23    model of the inner pane (e.g. type='canvas', model_id='canvas:scratch'
24    for a canvas-in-canvas embed). `pane` is the live pane reference,
25    re-resolved from pane_id at load. Rendering an embedded_view runs the
26    inner pane's update inside the element's bounds, so changes to the
27    shared model propagate as in any other view. Press 'E' with the cursor
28    over a canvas to spawn one (V1: hardcoded to embed canvas:scratch).
29    Self-recursion (a canvas embedding its own model) is blocked with a
30    placeholder render.

2     Anchor app — Phase 1, end of step 4 (workspace + template loader).
3   
4     This file is the entry point: it sets up the engine, theme, fonts, the UI
5     layer, then delegates per-frame rendering to the workspace shell. The
6     workspace walks a template (slots), looks up which pane is in each slot
7     (mode binding), and calls each pane's :update(dt, input, rect).
8   
9     Update vs draw: all UI work — hit-testing, state machine, layer command
10    queueing — runs from `update(dt)`. `draw()` is two lines that flush the UI
11    layer to the screen. See `docs/ui_architecture.md` § 4 "Why one method, not
12    two" for the reasoning.
13  
14    Resolution model: see plan.md "Resolution Model". UI code is written in raw
15    logical pixels. dpr=1 today on a single 1920×1080 monitor; the engine handles
16    device-pixel sizing internally when dpr changes (HiDPI / WASM publishing).
17    Nothing in this file should assume dpr=1.
18  
19    Filter mode: every UI layer + font is smooth (SDF edges, grayscale atlas,
20    linear sampling). Rough mode is reserved for embedded pixel-art game views.

10    Element shapes (in self.elements):
11      {type='image',         blob_id='blob:<hex>.<ext>', image=<image>, x=, y=, w=, h=}
12      {type='embedded_view', pane_id=<string>, pane_type=<string>,
13                             model_id=<string>, pane=<pane instance>, x=, y=, w=, h=}
14  
15    Image elements: blob_id is the persisted reference. `image` is the
16    live texture handle, re-resolved from blob_id on load. x/y are top-
17    left in canvas-local coordinates. w/h are the rendered size, starting
18    at native image dims and changing as the user resizes.
19  
20    Embedded-view elements (step 8): a *pane* hosted as a canvas element.
21    pane_id is the auto-generated stable id under which the inner pane is
22    registered in `panes`. pane_type + model_id are the type + backing
23    model of the inner pane (e.g. type='canvas', model_id='canvas:scratch'
24    for a canvas-in-canvas embed). `pane` is the live pane reference,
25    re-resolved from pane_id at load. Rendering an embedded_view runs the
26    inner pane's update inside the element's bounds, so changes to the
27    shared model propagate as in any other view. Press 'E' with the cursor
28    over a canvas to spawn one (V1: hardcoded to embed canvas:scratch).
29    Self-recursion (a canvas embedding its own model) is blocked with a
30    placeholder render.

2   name: Anchor App keybindings should be mode-scoped once modes land
3   description: Structural app commands (embed copy/paste, pane swap, undo, mode switch) are infrequent and must not collide with frequent in-mode commands like text Ctrl+C; partition the chord space via mode-scoped keybinds when modes get keybinding maps.
4   type: feedback
5   originSessionId: 1911f14a-9f08-4c0f-8e89-4aa44a78e8c9
6   ---
7   Anchor App keybindings should be mode-scoped once modes land. Structural commands operating *on* the workspace (view clipboard via Ctrl+Shift+C/V, pane swap via Ctrl+drag, embed spawn via E, mode switch via F1..F4) stay workspace-global because they're rare and apply regardless of what you're inside. In-mode commands (text Ctrl+C/V/B/I in Writing mode, code Ctrl+/ in Code mode, etc.) are mode-scoped and the active mode's pane gets first claim on those chords.
8   
9   **Why:** today everything is workspace-global because there's only one mode of operation and no prose typing yet. The moment Phase A (text editing) lands, plain Ctrl+C has to mean "copy this text" — not "capture the focused pane to view clipboard." Current placeholder bindings (E to spawn embed, Alt+click to address outer canvas, Ctrl+Shift+C/V for view clipboard) were chosen to be cheap to revise; user explicitly said the structural commands are infrequent in real usage so collision avoidance is the priority, not keybind ergonomics for those.
10  
11  **How to apply:**
12  - When adding any new keybinding in `Anchor2/app/`, ask: "is this structural (works regardless of mode) or in-mode (only meaningful in the active mode)?" Structural goes in `workspace.lua`-style global handlers; in-mode goes in mode-specific keymaps once those exist.
13  - When implementing Phase A text editing: Ctrl+C/V/X/B/I/A and friends MUST be handled by the focused text element / pane and shadow any workspace-global bindings on the same chord.
14  - Resolution rule when modes get keymaps: focused-pane's mode claims a chord first, then workspace global. Or use a clear modifier convention (e.g., Ctrl+Alt+X for all structural commands) so prose typing never accidentally fires a structural action.
15  - Don't bikeshed the current placeholder structural chords until modes land — they're explicitly temporary.

2     workspace — the shell that hosts panes in slots defined by a template.
3   
4     Two registries + one piece of state:
5       workspace_templates  template name → ordered list of slot definitions
6       workspace_modes      mode name     → {template=<name>, panes={slot=pane_id, ...}}
7       workspace_state      active mode + cached resolved template + slot→pane map
8   
9     Templates are ordered arrays of slot defs. The order matters: edge slots
10    cut from the workspace rect one at a time in declaration order, then a
11    fill slot (if present) takes whatever's left. Each slot def is one of:
12  
13      {name='status_top', edge='top',    size=24}
14      {name='status_bot', edge='bottom', size=22}
15      {name='side_a',     edge='left',   size=320}
16      {name='side_b',     edge='right',  size=360}
17      {name='main',       fill=true}
18  
19    Modes bind specific pane ids to slot names. Two modes can share a
20    template — pane assignment is decoupled from layout.
21  
22    Per-frame work (called from main.lua's update(dt)):
23      1. workspace_compute_slot_rects() walks the template, returns
24         {slot_name → rect}.
25      2. For each (slot, pane_id) in the active mode's binding, look up the
26         pane in `panes` (from pane.lua) and call pane:update(dt, input,
27         slot_rect).
28  
29    Step 4 implements only this. Drag-to-swap (step 5), mode switching with
30    persistence (step 6), and splitter resize / free-form override

2     undo — global undo / redo stack.
3   
4     Commands are plain tables with `apply` and `revert` methods. The
5     stack is LIFO; pushing a new command clears the redo stack. Each
6     pane (or whatever else mutates state) builds its own commands; this
7     module only manages the stack and the keybindings.
8   
9     Two construction patterns are both supported:
10  
11      "Apply on push" — the gesture creates the cmd, calls cmd:apply(),
12      then undo_push(cmd). Apply/revert are symmetric so redo works
13      identically. Used for atomic actions like add/delete.
14  
15      "Already applied" — the gesture has already mutated state in place
16      (e.g., the per-frame mutations during a drag). The cmd captures
17      pre + post state; gesture pushes without calling apply. Used for
18      continuous operations where the gesture IS the apply.
19  
20    Commands should be self-contained — reference state via stable
21    identifiers (pane_id strings, element refs by table identity).
22    Don't capture transient state that might change between push and
23    revert (e.g., the current selected_idx).
24  
25    Stack is global (one undo history shared across all panes). User
26    expects Ctrl+Z to undo "the last thing I did" regardless of which
27    pane the action targeted; commands target their pane via pane_id.

2     pane — class + type registry for workspace panes.
3   
4     A pane is a long-lived stateful UI object: file browser, agent panel,
5     code editor, status bar, etc. Each pane has:
6       - id        stable string identity, used in templates / persistence
7       - type      string, looked up in pane_types for behavior
8       - state     per-instance state table (scroll, cursor, fold-state, etc.)
9       - model_id  optional reference to a model (for view/model split)
10  
11    Pane types vs subclassing
12    -------------------------
13    Anchor 2's class() has no inheritance ("if you want a variant, copy and
14    modify"), so we don't subclass pane for each type. Instead:
15  
16      - There is ONE pane class with shared lifecycle plumbing.
17      - Each pane TYPE is a plain table of callbacks registered in
18        pane_types via pane_register_type(name, def).
19      - pane:update / :serialize / :destroy dispatch to the type's
20        callbacks if present.
21  
22    This keeps the stateful object (genuinely OOP) separate from the
23    per-type behavior (procedural data), matching the framework convention.
24  
25    Why panes don't use make_entity
26    -------------------------------
27    Panes manage their own registry (panes, keyed by pane.id) and have an
28    explicit destroy step. They don't need the entity system's collision
29    events, deferred kill queue, or numeric ids. If a specific pane type
30    needs entity integration later, its init callback can call

1    # Anchor App UI Discussion
2   
3   Captured 2026-04-28. Updated 2026-05-11 (Phase 1 Part 3 — embedded views,
4   view clipboard, recursive input routing, and visual focus feedback
5   shipped; Phase 1 foundation is now complete except for text editing,
6   deferred to Part 4 / focused-plan Phase A). Authoritative reference for
7   the app's UI architecture. If you are a future session picking this up,
8   read this file *after* `plan.md` and *before* writing any UI code — most
9   of the decisions here are non-obvious from the codebase alone and were
10  settled by long discussion.
11  
12  The visual side of the UI is covered separately: see `docs/visual_identity.md`
13  and `docs/mockup_v2_ui_kit.html` (the authoritative visual reference). This
14  file is the *system architecture*: how the UI is structured in code, what the
15  units of composition are, how state flows between them.
16  
17  ---
18  
19  ## TL;DR
20  
21  - **Hybrid mode UI**: retained workspace shell (panes are long-lived stateful objects you can drag between slots) + immediate-mode widget functions inside panes (buttons, chips, rows — drawn each frame from state).
22  - **Two-tier layout**: a workspace template defines named **slots** (edge slots + one fill slot); each mode assigns specific **panes** to those slots. Slot names are positional and generic (`side_a`, `main`, `status_top`); pane names are stable identities (`code_editor`, `agent_oracle`).
23  - **RectCut** is the layout primitive inside panes. Small module (~50 lines), mutating-parent style, supplemented by helpers (contract, center, split_h/v).
24  - **Model–view separation** (✅ shipped Phase 1 Part 2 step 7): a separate `models` registry holds canvases, files, conversations etc. Each model has `{id, kind, version, content}`. Panes are *views* of models — they hold `self.model_id` and dereference via `model_get(id)`. Multiple panes can view the same model; edits propagate via per-frame version polling (`self.last_seen_version != self.model.version → re-validate view-local state`).
25  - **Two host types** for panes (✅ shipped Phase 1 Part 3 step 8): workspace **slot** host or canvas-**element** host (`embedded_view` element type). Same pane class either way — what differs is who calls `pane:update(dt, input, rect)` with what rect. Elements persist their `pane_id`, `pane_type`, `model_id` + bounds; the inner pane is created idempotently on load via `pane({id=..., type=..., model_id=...})`.
26  - **Pane content uses canvas-local coordinates** (✅ shipped Phase 1 Part 2 step 7b): element `(x, y)` is offset from the canvas origin (its pane's rect top-left), not from the window origin. Rendering translates by `(rect.x, rect.y)` via `layer_push`; input is translated the other way (`cx = mx - rect.x`). Two panes viewing the same canvas render identical content at identical canvas-local positions — the property that makes embedded views work.
27  - **Workspace owns input routing** (✅ recursive routing shipped Phase 1 Part 3). Drops drain once at the workspace; clicks, drops, focus-on-click, and cursor authority all resolve to the **deepest pane under the cursor** via `pane:find_pointer_target(cx, cy, rect)`, which walks into embedded views by default. The canvas type's callback applies override rules in priority order: (a) Alt held → outer wins (the "address the host" modifier); (b) outer has a selected element with cursor inside its bounds → outer wins (modal selection — clicks on an already-grabbed embed stay with the host); (c) cursor over an embedded view → recurse into it; (d) otherwise the host wins. Panes gate pointer-driven input on `pane_owns_pointer(self)`; drag continuations are NOT gated so a move/resize that started in one pane can wander out without being interrupted.
28  - **Indirect-cycle guard** (✅ Phase 1 Part 3): the canvas type maintains a module-local `rendering_panes` set so a pane that re-enters its own update during a frame's render walk (A embeds B embeds A, easy to construct via copy/paste) short-circuits with a red placeholder instead of stack-overflowing. Direct self-embedding is caught at the element level by `el.model_id ~= self.model_id`.
29  - **Selection by element reference, not index**. When another pane deletes an earlier element, indices shift; refs don't.
30  - **Click-outside-deselect** (✅ Phase 1 Part 3): a click anywhere a pane doesn't own clears that pane's `selected_el`. Combined with the existing same-pane empty-click branch, this gives the uniform rule "clicking outside the selected thing deselects it" regardless of pane boundaries.

31  ## What's already shipped
32  
33  Phase 1 Parts 1, 2, and 3 of the original plan. Full ledger in `plan.md` `## Current Status`. Short version:
34  
35  - **Workspace shell**: panes, slots, templates, modes (F1/F2/F3 + F4 split), persistence, Ctrl+drag pane swap.
36  - **Canvas pane**: drop image files from disk, select/move/resize/delete elements, undo/redo, persistence to `data/canvases/<name>.lua`.
37  - **Model layer**: shared models with version polling; two panes can view the same canvas.
38  - **Canvas-local coordinates**: two panes show identical content — the embed-friendly property.
39  - **Embedded views (step 8)**: a canvas can host another pane as an `embedded_view` element. Press E to spawn. Drops, clicks, keys, and cursor authority route to the deepest pane under the cursor; Alt addresses the host instead.
40  - **View clipboard (step 9)**: Ctrl+Shift+C captures the focused pane (or selected embed with dimensions); Ctrl+Shift+V pastes into the canvas under cursor.
41  - **Visible pane focus**: 1px lavender border around the focused pane, suppressed when an element inside it is selected so there's only one visual cue at a time.
42  - **Engine additions**: drop-event API, cursor API, focus-clickthrough hint, stencil-mask clear.
43  
44  The canvas + element + model architecture is correct and complete for the prose-writing scope. This focused plan exercises a small subset (mostly text elements on a single canvas at a time) and treats embedded views as already-available infrastructure that the story / website can use as soon as text editing lands.

5   ## Vision
6   
7   The omega app is the next evolution of Anchor: a single application for all creative work, built entirely with the Anchor engine. It replaces the scattered collection of tools (Notepad, NeoVim, Claude Code, Explorer, DAW, browser) with one unified environment owned completely by the user.
8   
9   The core insight comes from 4 months of using Claude Code daily: AI is good enough that you stop reading code. Once you stop reading code, you lose ownership of the codebase. Once you lose ownership, you realize what you actually needed to own wasn't the code — it was the *environment*. The code is replaceable. The environment shapes everything.
