+MS-LEAD → Mos: WI-6 #833 tuple now FULLY PEER-CONVERGED (MS-LEAD + homelab agree, no open divergence). CANONICAL TUPLE for your sign-off:
+• issue=#833; branch=feat/833-constrained-recovery-command off exact 07553ead (homelab resolved the name divergence to mine).
+• scope: constrained recovery cmd = the single ungated mutator + durable mosaic-context-refresh skill wrapper; recovery MINTS FRESH challenge + identical WI-5 receipt protocol, normal-path receipt replay FORBIDDEN (parity C4); skill framework-native in packages/mosaic/, auto-symlink via merged #824 bridge; OPUS-SECREV mandatory (§7); M1 Claude+Pi; red-first; no live/runtime mutation.
+• AC-1 (homelab-sharpened, adopt): deterministic observable truncation/mutation variants {absent, malformed, prefix-truncated, observable-adapter-mutation} NONE promote; PLUS a negative-capability test/doc assertion that tail-preserving middle-drop is NOT represented as receipt-detectable (disclosed T-C residual → WI-7 server-side evidence). Tail-only counts only if the concrete payload is deterministically malformed/observably-incomplete — NO category-wide claim.
+• review-lane: terra CODE + FRESH Opus SECREV (distinct ≠builder ≠planner-opus ≠ms-wi4-secrev ≠ms-wi5-secrev/secrev2 ≠all prior), exact-head directed scope D1-trust/fresh-challenge/replay-forbidden/recovery-parity/T27-honesty.
+• Boundary A (both concur): BYTE-BUILD ONLY — ship framework-native skill + test #824 bridge projection, NO live ~/.claude/skills mutation under §4 freeze.
+• Boundary B (both concur): HYBRID P6 admission — in-build red-first + standalone shipped-path recovery replay/ordering harness HELD UNFIRED for your FIRE (single ungated mutator, tests fresh-challenge parity; no FIRE inferred).
+NOT dispatched — awaiting your reconciled GO. On sign-off I encode the directive + dispatch ms-wi6-build (pi terra:high, red-first).
