PRIMARY COMMAND
10+
Create `BUILD_PR_SPRITE_EDITOR_PROJECT_INTEGRATION` for the HTML-JavaScript-Gaming repo. Implement the approved Sprite Editor project integration contract from `PLAN_PR_SPRITE_EDITOR_PROJECT_INTEGRATION` with small, surgical changes only. Enforce disabled-until-selected paint/stroke behavior, preserve locked palette behavior after explicit selection, persist and restore palette references safely across save/load, and keep new/load/import/resize/duplicate flows contract-compliant. Do not broaden scope beyond Sprite Editor project integration. Refresh `docs/dev/reports/change_summary.txt`, `docs/dev/reports/validation_checklist.txt`, and `docs/dev/reports/file_tree.txt`, and package a repo-structured ZIP to `<project folder>/tmp/BUILD_PR_SPRITE_EDITOR_PROJECT_INTEGRATION_delta.zip`.

`build(sprite-editor): integrate project palette selection and persistence contracts`
1314

14-
Goal:
15-
Implement a small, surgical Sprite Editor integration PR so palette flow uses engine authority and session/project lock rules.
16-
17-
Required integration rule:
18-
1. Sprite Editor must use engine paletteList as source of truth.
19-
2. Palette list is loaded from engine contract, not local hardcoded tool authority.
20-
3. Editing remains disabled until palette selected.
21-
4. Selected palette becomes locked for active project/session.
22-
5. Palette switching remains blocked unless explicit new/reset project flow is used.
23-
6. Lock behavior must match plan contracts for new project/load/import/resize/duplicate/save-load.
24-
7. No engine-boundary bypass and no duplicated palette authority inside tool.
25-
26-
Scope rules:
27-
- Do not review/modify legacy sprite editor implementations outside tools/Sprite Editor/
28-
- Keep scope small and surgical
29-
- Prefer public engine-facing contracts only
30-
- No unrelated engine/tool rewrites
31-
- Docs-first and one PR per purpose
32-
- Preserve file headers
33-

Packaging:

NEXT COMMAND
16+
MODEL: GPT-5.4
17+
REASONING: high
18+
COMMAND: After BUILD validation is complete, create `APPLY_PR_SPRITE_EDITOR_PROJECT_INTEGRATION` that verifies final repo readiness, confirms project-format compatibility, summarizes user-visible behavior changes, and packages the final repo-structured delta ZIP.

BUILD_PR target:
7+
Integrate isolated Sprite Editor project flow with engine-authoritative palette selection and locked palette project/session contracts.

9-
Planned BUILD focus:
10-
- engine-authoritative palette source in Sprite Editor
11-
- disabled editing until palette selection
12-
- locked palette semantics for active project/session
13-
- palette reference persistence contract in project JSON
14-
- clear fallback behavior when engine palette source is unavailable
9+
Implemented changes:
10+
- tools/Sprite Editor/index.html
11+
- Added engine palette bootstrap script include (`../../engine/paletteList.js`)
12+
- Added palette selector UI and lock-state readout
13+
- Kept color input as display-only (disabled) so palette swatches remain authority path
14+
- tools/Sprite Editor/modules/constants.js
15+
- Removed hardcoded default palette authority constants
16+
- Added palette contract constants (`PALETTE_SOURCE_ID`, `NO_PALETTE_ID`)
17+
- tools/Sprite Editor/modules/projectModel.js
18+
- Added `paletteRef` project contract
19+
- Updated new/load/serialize model behavior for palette reference persistence
20+
- Save serialization now stores palette identity (`paletteRef`) rather than authoritative palette catalog
21+
- tools/Sprite Editor/modules/spriteEditorApp.js
22+
- Added engine palette catalog loader from `globalThis.palettesList`
23+
- Added disabled-until-selected edit gate
24+
- Added explicit palette-selection lock flow
25+
- Enforced lock-preserving behavior for import/resize/duplicate operations
26+
- New project flow now unlocks palette and requires explicit re-selection
27+
- Load flow resolves paletteRef and auto-locks when available; unresolved refs fall back to blocked selection mode
28+
- Updated save/load status messaging for palette lock resolution
29+
- tools/Sprite Editor/spriteEditor.css
30+
- Added disabled control and select styling for clearer lock/gate UX
31+
- tools/Sprite Editor/README.md
32+
- Added project integration contract notes

# BUILD_PR_SPRITE_EDITOR_PROJECT_INTEGRATION
7+
8+
## Goal
9+
Implement the approved Sprite Editor project integration contract from `PLAN_PR_SPRITE_EDITOR_PROJECT_INTEGRATION` with small, surgical changes in `tools/Sprite Editor/` only.
10+
11+
## Approved contract implemented
12+
- Sprite Editor now consumes palette authority from engine `globalThis.palettesList` (loaded from `../../engine/paletteList.js`).
13+
- No local hardcoded tool-authoritative palette catalog is used for selection flow.
14+
- Editing remains disabled until a palette is selected.
15+
- Palette selection locks for the active project/session.
16+
- Palette switching is blocked after lock through normal interaction.
17+
- `Create New Canvas` is the explicit reset/new-project unlock flow.
18+
- Save JSON now persists `paletteRef` identity metadata.
19+
- Load JSON restores/locks palette by `paletteRef.id` when resolvable; unresolved refs load in blocked palette-selection state.
20+
21+
## Operation-specific lock behavior
22+
- New project (`Create New Canvas`): clears lock and requires new palette selection.
23+
- Load existing JSON:
24+
- resolvable `paletteRef.id` -> auto-lock to that engine palette
25+
- missing/unresolvable `paletteRef.id` -> blocked mode until explicit palette selection
26+
- PNG import: preserves current palette lock; no palette switching side effects.
27+
- Resize canvas: preserves current palette lock.
28+
- Duplicate frame: preserves current palette lock.
29+
- Save/load flow: persists and restores palette reference identity safely.
30+
31+
## Scope boundaries honored
32+
In scope:
33+
- `tools/Sprite Editor/index.html`
34+
- `tools/Sprite Editor/spriteEditor.css`
35+
- `tools/Sprite Editor/README.md`
36+
- `tools/Sprite Editor/modules/constants.js`
37+
- `tools/Sprite Editor/modules/projectModel.js`
38+
- `tools/Sprite Editor/modules/spriteEditorApp.js`
39+
- docs/reports for this BUILD
40+
41+
Out of scope:
42+
- engine rewrites
43+
- unrelated tools
44+
- pre-existing sprite editor implementations outside `tools/Sprite Editor/`
45+
46+
## Validation summary
47+
- Syntax checks passed:
48+
- `node --check tools/Sprite Editor/modules/spriteEditorApp.js`
49+
- `node --check tools/Sprite Editor/modules/projectModel.js`
50+
- `node --check tools/Sprite Editor/modules/constants.js`
51+
- Palette-gating and lock flows implemented per plan contract.
52+
- Save/load palette reference behavior implemented with unresolved-reference fallback to blocked mode.
53+
54+
## Packaging
55+
- Delta ZIP: `tmp/BUILD_PR_SPRITE_EDITOR_PROJECT_INTEGRATION_delta.zip`
56+
- ZIP includes only PR-relevant files.

## Project Integration Contract
36+
- Palette source of truth is engine-owned `globalThis.palettesList` from `engine/paletteList.js`.
37+
- Editing remains disabled until a palette is selected from the engine palette list.
38+
- Once selected, palette is locked for the active project/session.
39+
- Palette can only be changed through explicit new-project flow (`Create New Canvas`), which resets lock.
40+
- Saved project JSON persists `paletteRef` identity (`source`, `id`, `locked`) instead of storing an authoritative palette catalog.
41+
- Loading JSON attempts to resolve and lock `paletteRef.id` against engine palette list; unresolved refs load in blocked selection mode.
