+# RM-02 Governing Claim Index
+
+This index binds remediation claims that live in orchestrator-owned `TASKS.md` without modifying that file. The source heading and quoted text are the reviewable anchor; `gate:verify` enforces each marker-to-criterion binding. Marker completeness beyond this approved slice remains RM-54.
+
+## Prose is an enforceable claim
+
+<!-- GATE-CLAIM:PROSE-IS-A-CLAIM -->
+
+- Source: `docs/remediation/TASKS.md`, heading `D-20 — the orchestrator's own documentation overclaimed, and a reviewer disproved it empirically`.
+- Anchored text: “The defect was not in the code — it was in this file.”
+
+## Generated-state verification scope
+
+<!-- GATE-CLAIM:GENERATED-STATE-SCOPE -->
+
+- Source: `docs/remediation/TASKS.md`, heading `D-19 — an integrity property that cannot exist at the layer it was specified`.
+- Anchored text: “a verifier that cannot detect the attack is not a verifier.”
+
+## Criterion restatement provenance
+
+<!-- GATE-CLAIM:CRITERION-RESTATEMENT -->
+
+- Source: `docs/remediation/TASKS.md`, heading `D-18 — two pre-registered criteria were mutually unsatisfiable, discoverable only at implementation`.
+- Anchored text: “Both criteria were pre-registered. They cannot both be satisfied.”
