 ## Gate Results
 - Current branch: PASS - PR_26178_ALFA_001-fix-tags-local-api-crash
 - Started from main: PASS - branch was created after main was fast-forwarded from origin/main.
-- Worktree scope: PASS - only Tags service, Tags service test, and required reports are changed.
+- Worktree scope: PASS - only Tags service, Local API router, targeted Tags tests, and required reports are changed.
 - start_of_day unchanged: PASS.
 
 ## Validation Result
 - PR-scoped branch validation: PASS.
 
 ## Commands
 - `node --check src/dev-runtime/toolbox-api/alfa-tool-services.mjs` - PASS
+- `node --check src/dev-runtime/server/local-api-router.mjs` - PASS
 - `node --check tests/dev-runtime/TagsApiService.test.mjs` - PASS

 ## Out-of-Scope Observation
 - `node ./scripts/run-node-test-files.mjs tests/dev-runtime/DevRuntimeBoundary.test.mjs` - FAIL on an existing router assertion for `parts[1] === "local-db"`.

 - Confirmed no Tags page, browser-owned product data, local storage product source, MEM DB, or page-local product arrays were added.
 - Confirmed the public failure message no longer exposes raw missing-table details such as `relation "project_tags" does not exist`.
 - Confirmed the operator diagnostic still carries the raw cause for developer troubleshooting.
+- Confirmed the Local API route returns HTTP 503 JSON for Tags setup failures instead of allowing the async service rejection to escape.
+- Confirmed the API response body does not include `operatorDiagnostic`, raw relation text, table names, database URLs, hostnames, or credentials.
+- Confirmed Assets no longer triggers an async Tags database read while the Local API data source is being constructed.
 
 ## Expected Manual Behavior
 - With the Tags database schema applied, opening Tags and invoking the repository snapshot/list path should load seeded flat Tags from the API database.
 - If account, Game Hub, or Tags database setup is missing, Tags API requests should fail with a 503 setup message telling the operator to verify the API database connection and apply setup.
 - The service should not return fake data or silently treat missing schema as an empty Tags list.
+- After a Tags setup failure, the Local API server should continue handling other API requests.

 - Wrapped the shared Tags `readTables` flow used by `listTags`, snapshots, and tag write preflight reads.
 - Preserved raw database/schema details in `operatorDiagnostic` while returning Creator-safe actionable error text through the API error message.
 - Added `tests/dev-runtime/TagsApiService.test.mjs` for the Tags service read path.
+- Added a Tags repository API response mapper in `src/dev-runtime/server/local-api-router.mjs` so Tags setup failures return controlled HTTP errors.
+- Prevented Assets from eagerly calling the async Tags API service during Local API data-source startup by giving Assets a synchronous cached-tags facade.
+- Added `tests/dev-runtime/TagsApiErrorResponse.test.mjs` to prove Tags method failures return HTTP 503 JSON responses and do not escape the router.

 - PASS - Tags reads use API/Database contract: the service still reads via the injected database adapter and product tables.
 - PASS - Missing setup fails safely: public error text is actionable, status code is 503, raw cause is operator-only diagnostic.
 - PASS - Targeted tests cover `listTags`/`readTables`: new Node tests cover success, missing schema, and missing adapter paths.
+- PASS - Async Tags service errors are caught by the API layer: HTTP route test covers `listTags`, `getSnapshot`, and `addTag`.
+- PASS - Existing `statusCode` is preserved: `TagsApiSetupError` returns HTTP 503.
+- PASS - Browser response is Creator-safe: tests assert no relation name, raw table name, database URL, host, password, or operatorDiagnostic is present.
+- PASS - No setup failure is converted into empty arrays: Tags API methods return HTTP errors instead of successful empty data.
+- PASS - Node Local API server remains alive: route test confirms the router promise does not escape and a follow-up Tags constants request succeeds.
 - PASS - Required reports produced under `docs_build/dev/reports/`.
 - PASS - Repo-structured ZIP produced under `tmp/`.
 - PASS - No `start_of_day` folders modified.

+## Result
+PASS
+
+## Focus
+Tags Local API service and HTTP repository method error handling.
+
+## Validation Commands
+- PASS - `node --check src/dev-runtime/toolbox-api/alfa-tool-services.mjs`
+- PASS - `node --check src/dev-runtime/server/local-api-router.mjs`
+- PASS - `node --check tests/dev-runtime/TagsApiService.test.mjs`

+- PASS - `git diff --check`
+
+## Coverage
+- Tags service `listTags` reads and seeds through the API database adapter.
+- Tags service wraps missing schema/setup failures in `TagsApiSetupError`.
+- Tags API repository method route returns HTTP 503 JSON for `listTags`, `getSnapshot`, and `addTag` setup failures.
+- Browser response omits raw database details and operator diagnostics.
+- Router promise does not escape to the outer server catch, and the server remains responsive after the failure.
