+## Resolution

+Closed 2026-05-16 via audit-triage discovery of substrate drift:
+
+- **Deliverable shipped**: `docs/research/meta-cognition-survey-2026-04-21.md` (172 lines, 8 sections, all six acceptance criteria met)
+- **Drift class**: #1 (pure drift) — file's revision history shows 2026-05-10 implementation landing as "B-0037.1 implementation"; the row's `status: open` was never updated
+- **Acceptance verification** (zero gh, from current main):
+  - ✅ File exists and is committed
+  - ✅ Section 3 names all eleven implicit meta-cognitive moves classified by Order (First/Second/Third) in numbered table
+  - ✅ Section 8 includes the retractible-ceiling revision from Aaron's three-message correction arc with chronology preserved
+  - ✅ Section 4 includes six measurables candidates table
+  - ✅ Section 7 cross-references composing memory files + docs
+  - ✅ Pure doc addition — `dotnet build -c Release` unaffected
+- **Surfaced by**: `tools/hygiene/audit-backlog-status-drift.ts` candidate list + manual existence + content-coverage check
+- **Composes with**: parent B-0037 + siblings B-0037.2 / B-0037.3 / B-0037.4 (which remain open and depend on this row's deliverable per the survey doc's section 4 reference to B-0037.3)
