ROLE: Senior backend + security engineer. Implement PHASE 2 — FACTORY ENROLLMENT +
SCOPED ROTATABLE TOKENS (§12) for the fleet coordinator in platform-service, plus two
small artifact-route hardening fixes found in review.

PARALLEL-SAFETY (another Devin is running in a DIFFERENT repo — agent-queue/devops-tools —
on feature flags; no file overlap with you. Stay within platform-service):
- You OWN: a NEW modules/fleet/enrollment.ts, modules/fleet/tokens.ts (or one
  enrollment.ts), enrollment.test.ts, and ADDITIVE edits to types.ts, repository.ts,
  routes.ts, cosmos-init.ts (factory token fields + enrollment endpoints + token-auth
  middleware). You MAY edit artifacts-blob.ts/routes.ts ONLY for the two review fixes below.
- You MUST NOT change the scheduler.ts scoring, coordinator.ts claim/lease/fence CAS, or
  the heartbeat/claim PAYLOAD shape (only ADD an optional auth check around them, behind a
  flag — see below). Do not break any of the existing 79 fleet tests / 1591 platform tests.

READ FIRST:
- modules/fleet/types.ts — FleetFactoryDoc (id, productId, capabilities, health, load,
  lastHeartbeatAt...). repository.ts — factory upsert (heartbeat). routes.ts — POST
  /fleet/factories/heartbeat, POST /fleet/claim (these will optionally require a token).
- modules/auth/** in platform-service AND ../../packages/auth — reuse the EXISTING token/
  hashing primitives (bcrypt/sha-256 recovery-code pattern). Do NOT invent new crypto.
  Tokens are stored HASHED at rest; the plaintext is returned exactly once at enroll/rotate.
- ../learning_ai_devops_tools/agent-queue/docs/GIGAFACTORY/GIGAFACTORY_ROADMAP.md §12 (enrollment,
  scoped tokens, rotation, revocation) + §18 (trust boundary).

PREREQUISITE / BRANCHING: branch off CURRENT main → feat/gigafactory-p2-enrollment.
Push + open PR. DO NOT merge.

DELIVERABLES
1. Factory enrollment + token lifecycle (enrollment.ts):
   - enrollFactory({productId, capabilities, label?}) → creates/links a FleetFactoryDoc and
     issues a SCOPED token: scope = {productId, factoryId, capabilities[]}. Persist only the
     HASH (+ tokenId, createdAt, lastUsedAt, status). Return plaintext token ONCE.
   - rotateToken(factoryId, productId) → issue a new token, invalidate the previous (grace:
     mark old `rotating` with a short overlap TTL so an in-flight worker isn't cut off).
   - revokeToken(tokenId|factoryId, productId) → status=revoked; immediately rejected.
   - verifyToken(plaintext) → resolves {factoryId, productId, capabilities, status} or null;
     constant-time hash compare; updates lastUsedAt. Revoked/expired ⇒ null.
2. Token-auth on the fleet endpoints — GATED so existing tests keep passing:
   - Add a `requireFactoryToken` check to POST /fleet/factories/heartbeat and POST
     /fleet/claim that is ENFORCED only when enforcement is on (env/flag
     FLEET_REQUIRE_FACTORY_TOKEN, default OFF so the 79 existing tests are unaffected). When
     on: missing/invalid/revoked token ⇒ 401; token scope must cover the requested productId
     + the claim's capabilities ⇒ else 403. When off: behaves exactly as today.
   - The claim's effective capabilities/productId must be taken from the VERIFIED token scope
     when enforcement is on (a factory cannot claim outside its scope).
3. Routes (additive): POST /fleet/factories/enroll, POST /fleet/factories/:id/token/rotate,
   POST /fleet/factories/:id/token/revoke — all auth + productId + Zod validated, registered
   like the existing fleet routes (do not reorder others).
4. REVIEW FIXES (small, same module):
   - listArtifactsByJob must be productId-scoped: thread `productId` through
     repo.listArtifactsByJob + the GET /fleet/jobs/:id/artifacts handler (use the request
     productId), so a caller can only list artifacts for their own product.
   - Upload must prefer the request/auth productId over body.productId (drop the
     `body.productId ||` precedence; use getRequestProductId(req), body value only as a
     non-overriding hint or removed).

TESTS (enrollment.test.ts + targeted additions; tests are sacred, all prior green):
- enroll returns a plaintext token once; the stored doc holds only a hash (assert no
  plaintext persisted) + scope (productId, capabilities).
- verifyToken: valid → scope; tampered/unknown → null; revoked → null.
- rotate: old token still works during the overlap TTL, then is rejected; new token works.
- revoke: immediate rejection.
- enforcement OFF (default): heartbeat/claim behave exactly as the existing tests expect
  (re-assert claim works with NO token).
- enforcement ON: no token → 401; out-of-scope productId or capability → 403; in-scope → ok,
  and claim is constrained to the token's scope.
- artifact fixes: list is productId-scoped (a different product cannot see the pointers);
  upload ignores a spoofed body.productId.

VERIFY GATE:
- pnpm --filter @lysnrai/platform-service exec vitest run src/modules/fleet  (all green;
  count grows from 79)
- pnpm --filter @lysnrai/platform-service build
- pnpm build && pnpm test  (no regression across consumers)

CONSTRAINTS: ESM .js imports; no any; no console.log; productId on every doc; tokens HASHED
at rest, plaintext shown once; reuse existing auth/crypto primitives (no new schemes);
enforcement default OFF; conventional commits (feat(platform-service): ...); do not touch
scheduler scoring or the claim CAS; do not edit the agent-queue repo.

FINAL OUTPUT — report in EXACTLY this format:
## Implementation Report — Phase 2 Factory Enrollment + Scoped Tokens (§12)
### Branch & commits / PR
### Files changed
### What was implemented (enroll/rotate/revoke/verify, scope model, gated auth, artifact fixes)
### Tests added (+ pnpm test summary; esp. hashed-at-rest, scope 401/403, enforcement-off no-op)
### Verify gate results
### Deviations / assumptions (which crypto primitive, rotation overlap TTL, flag name)
### Suggested next slice
