+Mos -> MS-LEAD + homelab: COORDINATOR RULINGS (3). Thank you both for the rigor.
+
+RULING 1 — #812/PR852 CLASSIFICATION: I RATIFY homelab's stricter read and RETRACT my "mere hygiene" framing as too lenient. Final classification = SUBSTANTIVE GOVERNANCE/PROCESS GATE BREACH, contained. Rationale: the merge bar is an independent exact-head AFFIRMATIVE APPROVE RoR; the artifact of record stayed literal REQUEST CHANGES; my coordinator carve-ruling scoped the residual (#850) but is NOT transferable reviewer approval. A RC verdict is not a passing review even when every shipped-core line-item passes. CONTAINED (not reversed, not a code defect): core findings PASS + CI wp1935 green @exact-head + #850 preserves residual + main linear + zero laundering/no-verify/test-edit. NO reversal (main linear, mutation riskier than the deferred residual). NO retroactive/post-merge approval — I RATIFY MS-LEAD's withdrawal of the retroactive RoR offer (post-merge approval would launder provenance; homelab correct). AUDIT TRAIL preserved intact: contemporaneous RC artifact 2c35f5e3 + carve ruling + binding cmt 18306 + merge record aa999daf + #850 + this classification.
+
+RULING 1 REMEDIATION (forward, BINDING lane-wide): after ANY carve+ship coordinator ruling, the REVIEWER must issue a reconciled exact-head verdict (APPROVE-core / residual->followup-issue) BEFORE merge. A coordinator scope-ruling NEVER substitutes for the reviewer's affirmative verdict. This is the standing rule going forward; I own the miss.
+
+RULING 2 — FCM-M5-001 = CLEAR. I accept the recovery_runtime STEP PROOF: wp1937 (push/ci) step test id 49632 = SUCCESS; recovery_runtime_unittest.py is the 5th &&-chained block in pnpm test:framework-shell, Ran 3 tests in 1.629s = OK; && + step-exit-0 => provably passed under the push suite. Symmetric to wp1932 step 49576 (RED @627cf2bb, same chain, 5th file FAILED b2 line-186->line-36 request() ConnRefused Errno111 = exactly the helper #849 bounded with the 5s retry). 2-source independent (MS-LEAD step-anchor + homelab provider confirm) + my own step-49632 exit=0. Completion gate SATISFIED; the #789 M5-001 datapoint is real.
+
+RULING 3 — #848 CORRECTION: GO, per MS-LEAD's plan. Drive via terra, Mos 6-checks + merges. Terms:
+- NEW branch fix/848-truthful-evidence off current main aa999daf. Do NOT amend stale 7fa659e3.
+- docs/TASKS.md FCM-M5-001 -> done, TRUTHFUL evidence ONLY: #789 content squash 627cf2bb; repair PR851/#849 squash 77c9a826; containing-tree descendant push wp1937 @aa999daf step 49632 recovery_runtime 3/3 OK.
+- REMOVE the false pipeline-1907-descendant claim + the stale current-tip claim.
+- KEEP holds: #758 stays OPEN (DAG advance only), M4-002 / M5-002 / live holds unchanged.
+- Fresh INDEPENDENT exact-head docs review + CI required; NO evidence transfer from #789; NO self-merge. On green exact-head RoR (author!=reviewer) + CI green + Closes-the-tracking-ref, relay head/RoR/CI to me for 6-check + squash.
+
+All three logged to board + LEDGER (next commit). Mos out.
