verdict: READY
gaps: []

notes:
  - "task_contract present with mode=standard, requirements REQ-1..REQ-3, surfaces, invariants, risks, verification, regression_plan all populated."
  - "contract_policy.flow=full_spdd with sync_gate=required and verification_path=automated; reason explicitly states why standard reliability path applies."
  - "Each acceptance criterion AC-1..AC-4 has a matching verification row (VER-1..VER-4) plus an aggregate VER-5, and a matching regression_plan check (REG-1, REG-2)."
  - "All verification and regression commands are runnable pytest invocations against tests/test_entity_registry.py — no manual or placeholder steps."
  - "Files list is correctly scoped to mempalace_code/entity_registry.py (only place doing the direct write_text save at line 312) and tests/test_entity_registry.py (new file; no pre-existing entity_registry test module). Backlog metadata is not listed as a touched file."
  - "Design notes correctly call out same-directory temp file (parent of self._path), flush+fsync before os.replace, best-effort 0o600 chmod, temp cleanup on exception, and explicit preservation of the existing malformed-JSON load fallback (matches invariant INV-1 and ACs 1+3)."
  - "AC-2 design (monkeypatch the replace boundary to raise, verify prior bytes still parse to original data) directly proves the crash-safety contract from the backlog description without requiring real process crashes."
  - "Platform-aware permission handling in AC-4 acknowledges Windows / non-POSIX behavior; risk RISK-3 mitigation aligns."
  - "Out-of-scope list explicitly excludes broader atomic-write helper and onboarding files (aaak_entities.md, critical_facts.md), keeping blast radius small."
