+# Level 10.2B Workspace Manager Palette Binding Report
+
+## BUILD
+- `BUILD_PR_LEVEL_10_2B_WORKSPACE_MANAGER_PALETTE_BINDING_FIX`
+
+## Changed Files
+- `tools/shared/platformShell.js`
+- `tests/runtime/GamesIndexWorkspaceManagerOpen.test.mjs`
+- `docs/dev/roadmaps/MASTER_ROADMAP_ENGINE.md`
+- `docs/dev/reports/level_10_2b_workspace_manager_palette_binding_report.md`
+
+## Root Cause
+- Workspace Manager shared palette hydration in `platformShell.js` depended on catalog palette loading and an entries-oriented palette normalization path.
+- Active game palette data is now modeled under `game.manifest.json` at `tools["palette-browser"].palette` with `swatches` data.
+- Result: workspace opened without diagnostic but rendered `Shared Palette: No shared palette selected`.
+
+## Fix Applied
+- Added manifest lookup for game launch context (`games/<game>/game.manifest.json`).
+- Preferred shared palette source is now:
+  - `gameManifest.tools["palette-browser"].palette`
+- Added compatibility fallback read from root `palette` only when present.
+- No root palette objects were created.
+- Added resilient palette color normalization for `swatches`, `entries`, and legacy `colors` arrays before writing shared palette handoff.
+- Kept catalog-based palette hydration as fallback when manifest palette is unavailable.
+
+## Level 10.2A Test Update
+- Updated asset-presence assertions so shared asset selection is required only for games that declare non-palette catalog assets.
+- This prevents false negatives for games that only need palette hydration in this flow.
+
+## Validation
+- Command: `npm run test:workspace-manager:games`
+- Result: `PASS`
+- Workspace actions: `11`
+- `gameId` valid: `11/11`
+- `mount=game` valid: `11/11`
+- legacy `?game=` usage: `0`
+- shared palette present: `11/11`
+- asset presence failures: `0`
+- Bouncing-ball verification:
+  - shared palette present: `True`
+  - palette label: `Bouncing Ball Palette`
+  - shared asset label: `Bouncing Ball Classic Skin`
+  - no missing-palette message: `True`
+
+## Direct Launch Regression Check
+- Command: `npm run test:launch-smoke:games`
+- Result: `PASS` (`12/12` games)
+- Direct game launch behavior remained unchanged.
+
+## Constraints Check
+- No validators added.
+- No `start_of_day` files modified.

+# BUILD_PR_LEVEL_10_2B_WORKSPACE_MANAGER_PALETTE_BINDING_FIX
+
+## Objective
+Make Workspace Manager load the game's singleton palette as the shared palette.
+
+## Expected Manifest Palette Location
+Current model:
+
+```json
+{
+  "tools": {
+    "palette-browser": {
+      "schema": "html-js-gaming.tool.palette-browser",
+      "version": 1,
+      "name": "Palette Browser",
+      "source": "manifest",
+      "palette": {
+        "schema": "html-js-gaming.palette",
+        "version": 1,
+        "name": "Game Palette",
+        "swatches": []
+      }
+    }
+  }
+}
+```
+
+## Required Behavior
+When opening:
+
+```text
+/tools/Workspace%20Manager/index.html?gameId=<id>&mount=game
+```
+
+Workspace Manager must:
+1. Load `games/<game>/game.manifest.json`.
+2. Read:
+   ```text
+   tools["palette-browser"].palette
+   ```
+3. Bind it as the shared palette.
+4. Display its name/swatch count instead of:
+   ```text
+   Shared Palette: No shared palette selected
+   ```
+
+## Fallback Compatibility
+If older manifests still have root `palette`, Workspace Manager may read it temporarily as compatibility, but the preferred source is:
+
+```text
+tools["palette-browser"].palette
+```
+
+Do not create a new root palette.
+
+## Tests
+Run/update the Level 10.2A test so it catches:
+- Bouncing-ball missing shared palette
+- any other game missing shared palette despite manifest palette existing
+
+## Acceptance
+- Bouncing-ball no longer shows `Shared Palette: No shared palette selected`.
+- Games with manifest palettes show shared palette as loaded.
+- Level 10.2A test passes or reports only games genuinely missing palette data.
+- No direct launch regression.
+- No validators added.
+- No start_of_day changes.

+# PLAN_PR_LEVEL_10_2B_WORKSPACE_MANAGER_PALETTE_BINDING_FIX
+
+## Purpose
+Fix Workspace Manager shared palette binding for game manifests.
+
+## Problem
+Workspace Manager can load a game workspace without diagnostic, but still show:
+
+`Shared Palette: No shared palette selected`
+
+even when the game manifest contains palette data.
+
+## Scope
+- Bind Workspace Manager shared palette from the game manifest singleton palette tool section.
+- Keep direct game launch unchanged.
+- Use the Level 10.2A asset presence test to validate.
+- No start_of_day changes.
