### Data-Flow Trace (Level 4)

Applies to route and MCP layers that render dynamic user data.

| Artifact | Data Variable | Source | Produces Real Data | Status |
|----------|---------------|--------|-------------------|--------|
| `src/server/routes/items.ts` | items list | `getAllItems(db, userId)` → drizzle SELECT with `eq(items.userId, userId)` | Yes | FLOWING |

| `src/server/mcp/resources/collection.ts` | summary totals | `getGlobalTotals(db, userId)` | Yes | FLOWING |

### Behavioral Spot-Checks

Service-level tests run because `createTestDb()` is properly awaited in service tests.

| Behavior | Command | Result | Status |
|----------|---------|--------|--------|
| Item service — user isolation | `bun test tests/services/item.service.test.ts` | 13 pass, 0 fail | PASS |
| Category service — composite unique | `bun test tests/services/category.service.test.ts` | 9 pass, 0 fail | PASS |
| Thread service — resolve with userId | `bun test tests/services/thread.service.test.ts` | 34 pass, 0 fail | PASS |
| Setup service — item ownership validation | `bun test tests/services/setup.service.test.ts` | 20 pass, 0 fail | PASS |
| Totals service — user-scoped aggregates | `bun test tests/services/totals.test.ts` | 4 pass, 0 fail | PASS |
| CSV service — user-scoped import/export | `bun test tests/services/csv.service.test.ts` | 15 pass, 0 fail | PASS |
| Auth service — verifyApiKey returns { userId } | `bun test tests/services/auth.service.test.ts` | 5 pass, 0 fail | PASS |
| OAuth service — verifyAccessToken returns { userId } | `bun test tests/services/oauth.service.test.ts` | 12 pass, 0 fail | PASS |
| Item route tests | `bun test tests/routes/items.test.ts` | 2 pass, **9 fail** | FAIL |
| Category route tests | `bun test tests/routes/categories.test.ts` | 0 pass, **4 fail** | FAIL |
| Thread route tests | `bun test tests/routes/threads.test.ts` | 1 pass, **18 fail** | FAIL |
| Setup route tests | `bun test tests/routes/setups.test.ts` | 1 pass, **12 fail** | FAIL |
| Auth route tests | `bun test tests/routes/auth.test.ts` | 0 pass, **7 fail** | FAIL |
| MCP tool tests (all) | `bun test tests/mcp/tools.test.ts` | 0 pass, **18 fail** | FAIL |

**Root cause of all route and MCP test failures:** `createTestDb()` is an `async` function but is called without `await` in 7 route test files and `tests/mcp/tools.test.ts`. The destructuring `const { db, userId } = createTestDb()` assigns the raw Promise to `db` and `undefined` to `userId`, causing every DB operation to throw `TypeError: undefined is not an object (evaluating 'db.select')`.

The same issue affects `createSecondTestUser(db)` and `getCollectionSummary(db, userId)` calls in `tests/mcp/tools.test.ts`.

`tests/routes/oauth.test.ts` is the only route test that correctly uses `await createTestDb()`.

### Requirements Coverage

All 6 requirement IDs from plan frontmatter (`MULTI-01` through `MULTI-06`) are in scope for Phase 16.

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|-------------|-------------|--------|---------|
| MULTI-01 | 16-01, 16-02 | Every item, category, thread, and setup is owned by a specific user | SATISFIED | userId FK on items, categories, threads, setups in schema; all service functions scope by userId |
| MULTI-02 | 16-02, 16-03, 16-04 | User can only see and modify their own data (cross-user isolation) | PARTIAL | Service layer isolation verified by passing tests; route and MCP layer tested but test suite fails due to missing await — isolation logic in source code is correct |
| MULTI-03 | 16-01, 16-02 | Categories use composite unique constraint (userId + name) | SATISFIED | `unique().on(table.userId, table.name)` in schema; `getOrCreateUncategorized` respects it; category composite unique test passes |
| MULTI-04 | 16-01, 16-04 | Existing data is assigned to the original user during migration | SATISFIED | Migration (`drizzle-pg/0000_thankful_loners.sql`) exists with users table and userId columns; test infrastructure seeds user; no old single-user data to migrate (greenfield for multi-user) |
| MULTI-05 | 16-03, 16-04 | MCP tools operate within the authenticated user's scope | PARTIAL | Source code: `createMcpServer(db, userId)` and all tool registrations pass userId — correct. Tests: all 18 MCP tests fail due to missing await; MCP isolation tests do not run |
| MULTI-06 | 16-01, 16-02, 16-03 | Settings are per-user rather than global | SATISFIED | Settings table has composite PK `[userId, key]`; settings routes use `and(eq(settings.userId, userId), eq(settings.key, key))` and composite conflict target |

**Note on REQUIREMENTS.md state:** The file marks MULTI-01, MULTI-03, MULTI-06 as unchecked (`[ ]`) and MULTI-02, MULTI-04, MULTI-05 as checked (`[x]`). The implementation in the codebase satisfies all six at the source-code level. The checkbox state reflects that tests have not been fully verified green. This verification agrees — source-code satisfaction is confirmed, but test verification is blocked by the missing-await bug.

### Human Verification Required

None — all remaining gaps are code-level issues verifiable programmatically.

### Gaps Summary

The entire source-code implementation is correct and complete. The multi-user data model foundation is structurally sound:

- Schema uses pg-core with a users table and userId FKs on all 6 entity tables
- Composite unique constraint on `categories(userId, name)` and composite PK on `settings(userId, key)` are correct
- Auth middleware resolves userId for all three auth methods and removes the GET bypass
- All 7 service files accept userId and use `and(eq)` isolation on every get/update/delete query
- Thread resolution inserts new items with userId; setup sync validates item ownership
- All routes extract userId from context via `c.get("userId")`
- MCP server creation and tool registrations correctly thread userId

**The single root cause blocking goal achievement:** 7 route test files and `tests/mcp/tools.test.ts` call `createTestDb()` without `await`. Since `createTestDb()` is an `async` function that performs DB migration and seeding, omitting `await` means `db` receives the raw Promise object rather than the resolved Drizzle instance. Every database call then throws `TypeError: undefined is not an object`, causing 500 responses in route tests and TypeErrors in MCP tests.

Additionally, within `tests/mcp/tools.test.ts`, `createSecondTestUser(db)` and `getCollectionSummary(db, userId)` are also not awaited, breaking the 4 cross-user isolation tests in that suite.

Service-level tests (8 files) all pass because they correctly use `await createTestDb()`. The service-level cross-user isolation tests for items, categories, threads, and setups all pass, confirming the isolation logic works correctly at the service layer.

**Fix required:** In each affected test file, convert `createTestDb()` calls to use `await`. For files that use it inside synchronous helper functions (like `createTestApp()`), either make the helper async and await the call, or move the setup into a `beforeEach(async () => {...})` block.
