# B1 Completion Audit v001

Status: **CANDIDATE · B1 COMPLETION AUDIT · NO B2 UI · NO B3 BRIDGE · NO VPS MUTATION**

Baseline commit: `caa4788e6e1d1e060b5c66517c5fd82a014b0e59` (`target-v2/b1-hardening`)

Assignment: `B1_COMPLETION_AUDIT_ASSIGNMENT_v001.md`

## Review method

Re-read B1 assignment/handoff, B1 hardening handoff, B0 Platform Core handoff, and B0.UI schema-to-view matrix. Inspected migration SQL, `migrate.ts`, repositories, backup path, and Hub domain tests directly. Did not trust prior handoff claims without code/test verification.

## Checked contract items (15)

| # | Required scope item | Verdict |
|---|---|---|
| 1 | Ordered SQL migrations with checksum + deterministic schema versioning | PASS (001 retained; 002 added for immutability triggers; atomic apply + ledger) |
| 2 | Exactly 38 Hub relations including `employee_workspaces` | PASS |
| 3 | Composite/same-project FK enforcement + required indexes | PASS |
| 4 | Four catalog tables only (employees, employee_versions, memberships, runtime_bindings) | PASS |
| 5 | Roles labels / Skills typed refs / capabilities code-owned | PASS |
| 6 | Direct accountability + one planned assignee/reviewer per Task | PASS |
| 7 | `run_actors` observation only | PASS |
| 8 | `tasks.active_mission_id` + reservations + generation fencing | PASS |
| 9 | Context/version/artifact/authorization/history/idempotency/integration/access foundation | PASS after fix (tables existed; typed seams were incomplete) |
| 10 | `employee_workspaces` scope/provisioning identity, no raw Drive tokens | PASS |
| 11 | Typed repository layer + transaction boundaries | PASS after fix |
| 12 | principals/sessions/grants persistence | PASS |
| 13 | Deterministic command idempotency + optimistic revision checks | PASS |
| 14 | Backup foundation via SQLite Online Backup | PASS |
| 15 | Isolation / FK / revision / grants / reservation / long-poll tests | PASS (expanded) |

## Concrete gaps found / fixed

| ID | Severity | Finding | Disposition |
|---|---|---|---|
| A1 | Defect | Context/artifact/authorization/history/integration durable facts had SQL tables but no typed repository seams, so B1 item 9 was not mechanically enforceable/testable beyond table creation. | Fixed: added `registerArtifact`, `approveContextVersion`, `pinContextBundle`, `createMissionScope`, `recordAuthorization`, `appendBusinessEvent`, `recordBoundaryOperation`, `acceptInboxReceipt`, `registerWorker`, `createEmployeeVersion`. |
| A2 | Defect | `context_bundles` and `business_events` could be UPDATEd/DELETEd via raw SQL despite immutability/append semantics; artifact digests could be rewritten. | Fixed: migration `002_hub_immutability` adds fail-closed triggers (no 39th relation). |
| A3 | Gap | Inbox receipt replay-vs-conflict and worker durable identity lacked repository + regression coverage. | Fixed: helpers + tests (same-hash replay / different-hash conflict; worker key scope conflict). |
| A4 | Gap | Context bundle pinning and same-project artifact membership lacked focused tests. | Fixed: domain regression tests for pin replay/conflict, digest immutability, cross-project context artifact FK rejection, authorization same-project binding. |

No 39th Hub relation added. No B2/B3/Drive OAuth/Work auth/queue/VPS scope opened.

## Migration checksums

| Version | SHA-256 |
|---|---|
| `001_hub_foundation` | `9150c549deb341c63ef07472fad22fc0ff90c7400696bde8e567e0bbe24ce48e` |
| `002_hub_immutability` | `8186a95d572f07f9f9d713cc116eda59d777e4723f933be5598711cc6d1720a7` |

Checksum basis: UTF-8 SQL with LF newlines.

## Exact tests added / strengthened

Domain (`test/domain.test.ts`):

- empty-DB apply now expects both `001_hub_foundation` and `002_hub_immutability`;
- re-open checksum verification covers both ledger rows;
- project-scoped artifact register + digest immutability trigger;
- context version artifact membership + cross-project FK rejection;
- context bundle pin replay / different-manifest conflict + UPDATE immutability;
- business event append + UPDATE/DELETE append-only rejection;
- authorization bound to in-project mission scope;
- inbox receipt replay vs payload-hash conflict;
- boundary operation insert seam;
- worker registration identity + cross-scope conflict;
- employee_version catalog seam.

## Relation / forbidden-table checks

- Manifest remains exactly **38** (`HUB_RELATION_COUNT`).
- Forbidden absences unchanged: `roles`, `skills`, `capabilities`, `responsibilities`, `task_reservations`.
- Suite asserts empty-DB apply → 38 relations and forbidden-table absence (passed).

## Verification evidence — PLAN — 2026-09-18

From `target-v2/foundation` (clean sequence executed):

```powershell
cd target-v2/foundation
npm ci
npm run lint
npm run typecheck
npm test
npm run build
npm audit --omit=dev --audit-level=high
```

Also:

```powershell
git diff --check
```

Results:

| Check | Result |
|---|---|
| `npm ci` | PASS |
| `npm run lint` | PASS |
| `npm run typecheck` | PASS |
| `npm test` | PASS — 7 files / **50** tests |
| `npm run build` | PASS (web + hub) |
| `npm audit --omit=dev --audit-level=high` | PASS — **0** vulnerabilities (0 HIGH/CRITICAL) |
| `git diff --check` | PASS |
| Relation count | **38** |
| Forbidden tables absent | PASS |

## Deferred / explicit non-claims

Intentionally **not** implemented (out of B1 / deferred):

- B2 production UI/API vertical slice;
- B3 PLAN bridge / native whole-Mission execution;
- real Google Drive OAuth/API folder provisioning;
- Work auth;
- Redis/Temporal/queue/generic orchestrator;
- VPS/nginx/DNS mutation;
- legacy AA orchestration changes;
- full product CRUD for every Hub relation beyond the durable-fact seams required by B1 (e.g. decisions/blockers/results UI workflows remain B2+);
- treating role labels, profile text, skill refs, or Drive content as capability authority (still non-authoritative per B0 policy evaluator).

## Hand-off boundary

Completion here is implementation self-check only. Independent QA and Human Owner acceptance remain separate. Do not start B2 or B3 from this candidate.
