Merge Sim
fd2d2b7b0d
Four defects from a third review pass over the Codex subagent roster. `write()` set `lastSerialized` before the append and rolled it back only when the APPEND was refused. A refused PUBLISH left it set, so an identical replay short-circuited and the revision was never published again. The repo's own pattern is the opposite: `codex-structured-item-streams.ts` advances `checkpointLengths` only once the append AND the publish are both accepted. Roll back on either half. That alone did not cover the sweep, which is the LAST event a group ever gets: its `changed` guard skips the write on a retry because every child has already latched, stranding the settled roster's final revision. Write when the previous attempt was refused part-way, too. `formatWorkerTranscriptMessage` read `block.agents` as its exhaustive fallback. The journal schema deliberately admits block types this build does not know and `client.call` casts the RPC result instead of validating it, so a newer remote host's block reached that line and threw `agents is not iterable`, taking down the whole `worker read`. It printed a harmless `[image omitted]` before. Match `subagent-group` explicitly and degrade the unknown case. The elapsed clock measured to `now` whenever no child carried a terminal timestamp. That is exactly the roster restored from the journal after the host died: the reconciler latches `unverifiable` without a `settledAt`, so a child that ran four seconds reported the time since the crash as its run length, on a row that is not even counting. Show no duration when none is known. Also restores package.json to origin/main: the merge had deleted one of main's two duplicate `bench:terminal-partial-escape-tail` keys. Behaviour-preserving (JSON is last-wins and the deleted line was the dead one), but unrelated to this PR and better left to its own change. No gate rejects duplicate JSON keys. The new refusal tests also cover the append-side rollback, which had none.
