1. **P2 — Task 2, Step 1: a missing replicator incorrectly permits a completed release.**

   [`relocRelease`](/home/paulca/amadan.net/carlos/platform/.claude/worktrees/region-ha-two-box/docs/superpowers/plans/2026-10-07-region-ha-hostlife-two-box.md:1330) substitutes the current remote database position when the source’s replicator is gone, then returns a release with `Flushed=false`.

   Crash the live source during `releasing`, after admission closes but before the flush completes. The crash changes its epoch, making the retained database’s replicator stale. The model can journal the fallback release and advance to pinning.

   In 1b-next rev 19, `relocationFlushDB` refuses a missing replicator; `releaseDrain` propagates that error. `Release` permits recovery only from recorded flushed positions and matching stop evidence. Without those, release remains pending and eventually becomes stuck. Region HA §5.8 requires the same behavior.

   **Fix:** require the matching replicator or durable evidence of the completed flush and stop. Otherwise return no release. Add mutation-sensitive tests for a crash before the flush—no release or pin, then deadline—and successful replay after durable release evidence exists.

The pinned-manifest cleanup difference remains the documented at-rest-sweep abstraction: 1b-next’s completion queues local chores and abandoned prepared generations, not that manifest’s cleanup.

The four new Go files reconstructed in memory passed `gofmt` syntax checks. Compilation, runtime tests and mutations were not independently reproduced. No files changed or sweeps ran.

**FIRST PROMPT:**
“Follow the review brief docs/superpowers/plans/CODEX-PLAN-REGION-HA-TWO-BOX-BRIEF-6.md. Review the plan at commit b9d0046d.”

**WHAT:**
Check round 5’s disposition and report new findings.

**STATUS:**
Prior finding resolved; one new P2 release-fidelity finding.

**NEEDED:**
Nothing for this review.

**RECOMMENDED:**
Correct the missing-replicator release path and add the two crash tests.

**SESSION:**
Safe to close — no changes or processes left running.

**Verdict: not ready.**
