Subject: [PATCH] test(integration): un-skip 11 of 13 stale integration files
 (#3289)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The integration suite landed in #3292 with 13 files dark behind
describe.skip / --exclude, surfacing as #3289. This walks through
every umbrella item:

* auth-mock cluster (8 files) — vi.mock factory was returning a
  partial auth.js shape, so HTTPServer setup tripped on the missing
  optionalAuth import. Switched to importOriginal + override; spread
  the real exports so future auth additions don't re-break tests.
  Added matching csrfProtection mocks so POST/PUT/DELETE no longer
  403 on missing X-CSRF-Token.

* admin-sync-revenue-backfill, self-service-delete — were excluded
  from the script because vi.mock factories referenced top-level vars
  that aren't live until after factory hoisting. Moved shared state
  into vi.hoisted blocks; rewrote the WorkOS class mock so every
  `new WorkOS()` returns the same shared instance methods, so
  per-test mockImplementation overrides actually retarget the right
  spy. Removed --exclude flags from test:server-integration.

* health.test.ts — dropped the stale (server as any).registry.initialize()
  beforeAll (HTTPServer no longer exposes registry) and the two
  database-init tests that exercised it; kept the GET /health checks
  that still match the live response shape.

* mcp-protocol — bearer-auth gate cleared via MCP_AUTH_DISABLED at
  module-load time; the file now stays describe.skip pending an SSE-
  format response-parser update (the only remaining blocker is the
  StreamableHTTP transport returning text/event-stream by default).

* schema-routing — replaced localeCompare(numeric: true) with
  semver.rcompare so the test's idea of "latest in 3.x" matches the
  alias-rewrite middleware (which prefers stable over prerelease at
  the same X.Y.Z).

* digest-email-recipients — counts were hardcoded to a track-B size
  of 3; the cert curriculum grew to 4. Read the live count out of
  certification_modules so the test tracks curriculum changes.

* member-db — logo_url / brand_color / etc. aren't part of
  CreateMemberProfileInput anymore; the create handler doesn't
  persist them. Test reduced to the documented input contract.

* agent-visibility-e2e — fixed `src/db/migrations/...` path to
  `server/src/db/migrations/...` so the legacy-shape test reads the
  migration file CI ships.

* WORKOS_COOKIE_PASSWORD added to revenue-tracking-env.ts setup so
  AUTH_ENABLED resolves true in tests where production code reaches
  for `workos!.userManagement` and would otherwise hit a null deref.

Result: 46 / 50 integration files green (was 35), 596 tests pass
(was 465), 71 still skipped (was 139), 0 failures. Remaining
file-level skips and per-test skips have richer comments pointing
to #3289 with concrete next-step descriptions.

+ci: un-skip 11 of 13 integration test files tracked in #3289. Auth-mock cluster moves to `vi.mock(path, async (importOriginal) => ({ ...await importOriginal(), <overrides> }))` so HTTPServer setup finds the real `optionalAuth` and friends; CSRF middleware is mocked alongside auth so POST/PUT/DELETE tests stop hitting `403 forbidden`. The two `--exclude`'d files (`admin-sync-revenue-backfill`, `self-service-delete`) get `vi.hoisted` for shared mock state and class-form WorkOS mocks, so they load and run instead of erroring at module-eval. `health.test.ts` drops `(server as any).registry.initialize()` (the property is gone). `schema-routing.test.ts` re-aligns with `semver.rcompare` ordering. `digest-email-recipients` and `member-db` reconcile drifted assertions. The `--exclude` flags are removed from `test:server-integration`, and `WORKOS_COOKIE_PASSWORD` is set in the test env so the WorkOS client constructs in tests that need it. **+131 tests now run in CI**; remaining skips are documented in #3289 with concrete next steps.
