Summary

• When an approval (approved or rejected) resumes a parked call and no message run is open, the reactor opens one keyed on the approval message, so the re-dispatched call and its continuation emit the normal message.run.started and message.run.ended events.
• A reactor rebuilt after a restart or corbits resume previously ran an approved call with no open run. The TUI's reload deferral from fix(tui): defer agent reload until the reactor's message run ends #1486 keys on those events, so it could rebuild the agent mid-call on that path.
• When a run is already open (the live case), nothing changes.

Stacked on #1492 (which is stacked on #1485); review those first. The diff against its branch is this change only.

Verification

• bun run check and bun run test pass (9203 tests)
• The new reactor tests for a rehydrated approval and a rehydrated rejection fail on the base branch (no run opened) and pass on this branch; the live-run test passes on both
• All six fixes from this series applied together on current main pass bun run test (9202 tests) and the reload regression test passes 3 of 3 runs

Review · Approve

Opens a message run keyed on the approval's message id when a rehydrated parked call resumes with no run open, so idle-detectors can't rebuild the agent mid-continuation.

Findings

• vendor/intx-inference/src/reactor.ts:853 — follow-up to consider: the gate-cleared exclusion is correct for re-dispatched or answered parked calls, but a rehydrated async marker (no suspended call) resumed after restart still re-infers via the gate-cleared path with no run open. Pre-existing shape, not a regression; suggest either extending the open to that rail when no run is open or recording why the async rail is safe, with a mirroring test.

Superseded by #1494 (CL-10782). When an approval rehydrated from disk resumes with no message run open, #1494 holds the agent rebuild on the Corbits side until the resumed work replies or ends, so the reactor does not need to open a run and nothing changes under vendor/. We don't intend to merge or keep working on this PR. It stays open, as a draft, until #1494 lands, then it gets closed.

#1494 has landed, which is the close condition on this draft. Superseded: when an approval resumes with no message run open, the agent rebuild stays held on the Corbits side until that work replies or ends, so the reactor does not need to open a run and nothing under vendor/ changes. Closing the draft and CL-10777.
