Use one dispatchInternalPrompt surface with mode: async | sync so source, settle, hold, timeout, status checks, reservations, and release semantics stay in one runner. Keep the old helper names temporarily so caller migration can land atomically in follow-up commits.

- Wrap isSessionActive in withDispatchTimeout (capped at 5s) so a
stuck OpenCode SDK status() call cannot block internal prompts forever.
- Catch the timeout and treat session as inactive so the prompt can
proceed rather than hanging indefinitely.
- Add regression test: session.status that never resolves now times out
and allows dispatch instead of hanging the test (and production).
Refs: AGENTS.md internal-message-injection safety note
Preserve delegated child prompt/bootstrap metadata for early runtime fallback before OpenCode has persisted the first user turn. Bind prompt gate calls to the SDK session receiver and keep completed background task lookup visible across plugin manager instances.
BLOCKER-1 (dispatch deadlock): wrap session.promptAsync / session.prompt in
withDispatchTimeout() that uses Promise.race with a default 30s timeout.
Stalled upstream responses no longer hold the reservation forever.
BLOCKER-2 (post-dispatch failure released too early): collapse the
holdReservationAfterDispatch flag into a dispatchAttempted state so the
post-dispatch hold runs in the finally block regardless of whether
promptAsync resolved or threw. AGENTS.md's documented race window where
promptAsync 'returns before durably accepted, later failures arrive as
session.error' is now covered.
HIGH-6 (sync/async protocol duplicated): extract dispatchAfterSessionIdle
internal runner. promptAsyncAfterSessionIdle and promptAfterSessionIdle
become thin wrappers passing client.session.promptAsync vs prompt as
the dispatch callback. Future reservation semantics fixes apply once.
HIGH-7 (releasePromptAsyncReservation prefix foot-gun, partial): tighten
reservationSourceMatches to require prefix strings to end in ':' so
release cannot accidentally free reservations whose source merely starts
with the same identifier characters. Symbol token verification is still
internal-only as the audit invariant prevents external callers from
bypassing the gate.
Closes BLOCKER-1, BLOCKER-2, HIGH-6
Refs HIGH-7 (prefix hardened; token-required release deferred to follow-up)
Co-authored-by: gate-correctness (deep / gpt-5.3-codex high)
Keep prompt reservations briefly after successful dispatch so rapid idle/message/error transitions cannot inject the same follow-up twice.
Route all production session prompt calls through the shared gate, restore skipped background resume state, release holds after abort/recovery paths, and preserve Ralph/ULW loop state when a dispatch is deferred.
Add regression coverage for session routing, static prompt route auditing, team-mode live messaging, model suggestion retries, call-omo-agent reuse, background parent wakes, runtime fallback, compaction recovery, Atlas, and Ralph/ULW loops.
