 ## Purpose
-Polish the shared toolbox status bar context display so it shows only selected-game name/purpose on the left and categorized tool context in the center.
+Prove that Game Hub keeps existing project/game identity read-only while allowing normal create and metadata-edit workflows.
 
 ## Source Of Truth
-This `BUILD_PR.md` is the source of truth for `PR_26175_ALFA_002-toolbox-status-bar-context-polish`.
+This `BUILD_PR.md` is the source of truth for `PR_26175_ALFA_007-game-hub-project-readonly-proof`.
 
 ## Exact Scope
-- Do not include environment text in the status bar because environment already appears in the platform banner.
-- On the left side, display the selected Game Hub game name and selected Game Hub game purpose.
-- On the center side, display tool context messages for tool actions, save state, validation messages, warnings, or errors.
-- Preserve normal placement above the footer.
-- Preserve fullscreen/tool display mode bottom anchoring.
-- Preserve Idea Board selected-game filtering exclusion.
-- Preserve Game Hub as selected-game owner through the existing repository contract.
-- Keep the shared Theme V2 toolbox component model.
-- Update targeted Playwright coverage for the polished left and center context.
+- Add targeted Playwright proof that existing Game Hub project identity is read-only in edit mode.
+- Prove legacy Project Workspace project-information and project-record table controls are absent from Game Hub.
+- Prove source-idea child rows are read-only context, not editable project controls.
+- Prove add/create remains the only place where a new game name can be entered.
+- Preserve existing valid create/open/edit/delete behavior.
+- Do not change product UI or repository/API/service behavior unless targeted validation proves it is required.

 - No engine core changes.
 - No `start_of_day` folder changes.

+# PR_26175_ALFA_007-game-hub-project-readonly-proof Report
+
+## Overall Status
+PASS
+
+ALFA_007 adds targeted proof coverage that Game Hub keeps existing project/game identity read-only outside the create row. No product UI, repository, API, or service code changes were required.
+
+## Evidence Matrix
+
+| Requirement | Status | Evidence |
+| --- | --- | --- |
+| Replace BUILD source of truth with ALFA_007 | PASS | `docs_build/dev/BUILD_PR.md:1` identifies `PR_26175_ALFA_007-game-hub-project-readonly-proof`. |
+| Existing Game Hub project identity is read-only in edit mode | PASS | The proof test opens an existing row for edit and asserts the `Game` input value remains `Readonly Lantern Reef` with `readonly`: `tests/playwright/tools/GameHubMockRepository.spec.mjs:541`, `tests/playwright/tools/GameHubMockRepository.spec.mjs:543`, `tests/playwright/tools/GameHubMockRepository.spec.mjs:544`. |
+| Metadata edit controls remain available | PASS | The proof verifies `Purpose` and `Status` are not readonly: `tests/playwright/tools/GameHubMockRepository.spec.mjs:545`, `tests/playwright/tools/GameHubMockRepository.spec.mjs:546`. |
+| Legacy Project Workspace project panels are absent | PASS | The proof asserts Game Hub does not render legacy project-information or project-record tables: `tests/playwright/tools/GameHubMockRepository.spec.mjs:521`, `tests/playwright/tools/GameHubMockRepository.spec.mjs:522`. |
+| Source idea child rows are read-only context | PASS | The source-idea table has no buttons, inputs, textareas, selects, contenteditable elements, or role buttons: `tests/playwright/tools/GameHubMockRepository.spec.mjs:531`, `tests/playwright/tools/GameHubMockRepository.spec.mjs:532`, `tests/playwright/tools/GameHubMockRepository.spec.mjs:533`. |
+| Source-linked project destructive action remains unavailable | PASS | The proof expects `Delete Open Game` to be hidden for the source-linked active game: `tests/playwright/tools/GameHubMockRepository.spec.mjs:525`. |
+| Add/create remains the place where new game names can be entered | PASS | The proof opens the add row and verifies the create-row `Game` input is editable and not readonly: `tests/playwright/tools/GameHubMockRepository.spec.mjs:549`, `tests/playwright/tools/GameHubMockRepository.spec.mjs:551`, `tests/playwright/tools/GameHubMockRepository.spec.mjs:552`. |
+| Preserve product behavior and contracts | PASS | ALFA_007 changes only `tests/playwright/tools/GameHubMockRepository.spec.mjs` plus build/report artifacts. |
