-## Purpose
-Add CI-safe utils rule enforcement after the `src/engine/utils` to `src/shared/utils` consolidation lane.
+Model: GPT-5.4
+Reasoning: high
 
-## Command
-Run this from the repository root:
+```text
+Run BUILD_PR_LEVEL_11_83_LOCK_ASSET_LOADING_TO_MANIFEST_ONLY.
 
-```powershell
-powershell -ExecutionPolicy Bypass -File .\scripts\PS\enforce-utils-rules.ps1 -Details
-```
+Implement a targeted fix so Workspace Manager/game launch asset loading uses game.manifest.json as the only source of truth for game chrome assets. Do not guess /games/<Game>/assets/images/bezel.png or background.png. Do not add fallback assets. Do not add aliases or pass-through shims.
 
-For CI/regression mode:
+Tasks:
+1. Find code that derives game chrome image paths by convention, especially bezel/background.
+2. Replace convention-derived URLs with explicit manifest asset lookup.
+3. If a manifest does not declare an optional chrome asset, skip rendering/requesting that image and show safe empty state.
+4. Preserve games that already declare chrome assets in game.manifest.json.
+5. Search the repo for remaining hardcoded or derived references to /assets/images/bezel.png and /assets/images/background.png and remove convention-only loading paths.
+6. Run targeted validation only:
+   - launch SolarSystem and verify no bezel/background 404s
+   - launch a game with declared manifest chrome assets, such as Asteroids if available, and verify declared assets still load
+   - run syntax/import checks for changed JS files
+7. Write evidence to docs/dev/reports/asset_manifest_only_validation.md.
+8. If roadmap status is touched, status-only update only.

+# PR 11.83 Asset Manifest-Only Validation
+
+## Scope
+Lock game chrome asset loading (background/bezel) to explicit `game.manifest.json` declarations only.
+
+## Files changed
+- `src/engine/runtime/gameImageConvention.js`
+- `src/engine/runtime/backgroundImage.js`
+- `src/engine/runtime/fullscreenBezel.js`
+
+## Implementation summary
+- Removed convention-only chrome path derivation for:
+  - `games/<Game>/assets/images/background.png`
+  - `games/<Game>/assets/images/bezel.png`
+- Added manifest-driven chrome resolution via `resolveManifestChromeAssetPaths(...)`.
+- Background and bezel runtime layers now:
+  - resolve chrome image paths from `game.manifest.json`
+  - skip image request/render when manifest does not declare the optional asset
+  - keep loading declared chrome assets when present (for example Asteroids bezel)
+
+## Validation commands and evidence
+
+### 1) Syntax/import checks for changed JS files
+- `node --check src/engine/runtime/gameImageConvention.js`
+- `node --check src/engine/runtime/backgroundImage.js`
+- `node --check src/engine/runtime/fullscreenBezel.js`
+- Result: PASS
+
+### 2) Runtime convention-path removal scan (runtime code)
+- Command:
+  - `rg -n "assets/images/bezel\\.png|assets/images/background\\.png|toImagePath\\(|games/.*/assets/images/(bezel|background)\\.png" src/engine/runtime`
+- Result: no matches in `src/engine/runtime`
+
+### 3) Targeted SolarSystem/Asteroids behavior check
+- Executed targeted runtime validation script (inline Node ESM) that:
+  - loads `games/SolarSystem/game.manifest.json`
+  - loads `games/Asteroids/game.manifest.json`
+  - verifies SolarSystem makes no chrome image request when manifest has no chrome image entry
+  - verifies Asteroids requests declared manifest bezel image
+- Result output:
+  - `VALIDATION_PASS SolarSystem no chrome image request; Asteroids manifest bezel request present.`
+
+### 4) Browser launch smoke (games) for regression signal
+- `node tests/runtime/LaunchSmokeAllEntries.test.mjs --games`
+- Result: PASS (`12/12` games)
+- Includes PASS for:
+  - `Asteroids`
+  - `SolarSystem`
+
+## Remaining literal bezel/background path references
+- Remaining matches are in tests/docs/manifest data and not convention-loader runtime code.
+- Command used:
+  - `rg -n "assets/images/bezel\\.png|assets/images/background\\.png" src games tools samples tests`
+
+## Acceptance check
+- SolarSystem no longer relies on guessed `background.png`/`bezel.png` runtime convention loading.
+- Asteroids still loads declared chrome asset from manifest (`image.asteroids.bezel`).
+- No fallback assets, aliases, shims, or guessed chrome-path loader logic added.

+# PR 11.83 — Lock Asset Loading To Manifest Only
+
+## Purpose
+Prevent game/tool launch code from requesting guessed asset paths such as `bezel.png`, `background.png`, sample defaults, or hidden fallback assets that are not explicitly declared in the owning manifest.
+
+## Scope
+- Game launch/chrome image loading
+- Workspace Manager game/tool asset display paths
+- Manifest-driven asset lookup helpers if present
+- Targeted validation only
+
+## Required behavior
+1. Treat `game.manifest.json` as the source of truth for game assets.
+2. Only request an asset URL when the manifest explicitly declares that asset.
+3. If an optional asset is missing from the manifest, render a safe empty state.
+4. Do not hardcode or guess these paths:
+   - `/games/<Game>/assets/images/bezel.png`
+   - `/games/<Game>/assets/images/background.png`
+   - any other convention-only asset path
+5. Do not add silent fallback data or hidden default assets.
+6. Do not create aliases, bridge helpers, or compatibility shims.
+
+## Specific known failure to fix
+SolarSystem currently logs 404 requests similar to:
+
+```text
+GET /games/SolarSystem/assets/images/bezel.png 404
+GET /games/SolarSystem/assets/images/background.png 404
+```
+
+Those requests must stop unless SolarSystem declares those assets in its `game.manifest.json`.
+
+## Implementation direction
+- Locate the launch/chrome code that currently derives bezel/background image URLs by convention.
+- Replace convention-derived path construction with manifest lookup.
+- Support existing manifest asset entries such as:
+
+```json
+"image.asteroids.bezel": {
+  "path": "/games/Asteroids/assets/images/bezel.png",
+  "kind": "image",
+  "source": "workspace-manager"
+}
+```
+
+- Prefer an explicit manifest key lookup when keys are known.
+- Otherwise scan manifest asset entries for `kind: "image"` and a semantic key suffix/name such as `bezel` or `background`.
+- If no matching manifest asset exists, return `null` and skip image rendering/requesting.
+
+## Out of scope
+- Do not create missing image files.
+- Do not add placeholder images.
+- Do not change game art.
+- Do not refactor the manifest schema unless required for the fix.
+- Do not modify unrelated games/tools.
+
+## Acceptance
+- SolarSystem no longer requests nonexistent `bezel.png` or `background.png`.
+- Asteroids or any game with manifest-declared chrome assets still displays those assets.
+- No hardcoded convention fallback remains for game chrome assets.
+- Targeted browser validation shows no missing image 404s for affected game launch path.
