 reads do not prove recipient liveness, goal completion or Claude Desktop registration,
 and do not add automatic reply delivery or a reverse Claude transport.
 
+### Bounded reply waiting
+
+`codex_wait_reply` takes the same thread, receipt and optional cursor as
+`codex_read_reply`, plus an optional integer `waitMs` from 1 to 20,000 (default
+20,000). It makes at most three read snapshots with a two-second pause between
+them. The time budget includes all helpers and pauses; each snapshot reuses the
+existing scoped read validation and text limits. At most nine sequential helper
+invocations are possible per wait. Observation age is measured from the start of
+the last successful snapshot, including its metadata reads and helper cleanup.
+Waits share the host's four-operation limit.
+Each wait holds a slot for its entire lifetime: up to 20 seconds of waiting, plus
+time to terminate its helper. Four concurrent
+waits can make sends and metadata calls return busy; excess calls are rejected,
+not queued. Use fewer parallel waits when send capacity must remain available.
+
+Waiting only reads stored data; it does not resume an unloaded recipient. When
+work must continue, the user opens/resumes the selected conversation through the
+native Codex client. Message submission and reply waiting remain separate calls.
+
+An eligible final text returns immediately with `waitOutcome: reply_observed`,
+even if that text already existed. This is not a new-message subscription or
+exclusive reply ownership. An ambiguous input returns `ambiguous`. A non-null
+next page without eligible text returns `needs_pagination`; pass `nextCursor`
+back to continue. The tool does not silently scan all history.
+
+Otherwise, the tool refreshes the matched turn or repeats the same search
+position until the time or snapshot limit, returning `wait_exhausted` with the
+last successful observation. `attempts` counts snapshots attempted and
+`lastObservationAgeMs` describes that observation's age. A snapshot counts only
+when every read behind it completed before the deadline; helper shutdown that
+finishes after the deadline does not discard such a snapshot, and a snapshot
+whose reads completed late is treated as expired even if its data looks valid.
+A timeout with no successful observation, a read failure, or cancellation is
+unavailable. A read failure is not converted to an empty successful wait.
+
+Stored `turnStatus` from another helper can differ from the executing server's
+live state, so even a stored terminal status does not stop the wait early.
+Refresh revisits partially written items; callers still manage pagination and
+update item IDs. Cancellation/disconnect clears pauses and reaps owned helpers.
+The host adds no background watch, automatic delivery, session creation or resume.
