Ouroboros 35fbf7616c Show since when a reviewer has been awaited, only where the host knows it
On 2026-09-19 a task sat parked behind a reviewer for 7 h 16 min and the task
card gave no hint for how long. PR #1159 made the wait itself visible — a plan
wave or an acceptance panel lists an unanswered reviewer as
`Awaiting answer: <slot> · <model>` — but never said WHEN the host sent that
reviewer its request.

The rule is that a time is never invented, inferred or back-filled. A row whose
send moment the host did not record keeps exactly the text it has today.

The moment is recorded once, at the source: `ActiveReviewAttempt` gains
`started_at`, stamped with `utc_now_iso()` only where this process creates the
entry for a NEW physical operation. The free replay of an already settled answer
is not stamped, and neither is an `exact_recovery` rejoin: that operation was
sent by an EARLIER process and its send moment is persisted nowhere, so this
process honestly has nothing to show.

`ReviewActorRecord` gains `awaiting_since`, set from the entry onto the two rows
that wait — the `pending_dispatch` row released at the dispatch barrier and the
`in_flight` row whose window expired. A settled or answered row never carries it.
The plan row and the durable wave actor record carry it forward beside the other
custody facts, so it reaches `wave.actors`; `_review_actor_projection` publishes
it for `panel.actors` only when one of the two existing wait predicates still
calls the row unanswered AND the stored value parses as an instant — otherwise
the key is absent.

The browser appends ` · since HH:MM` in the viewer's local 24-hour clock, with
the short local date when the wait began on an earlier day so `since 23:50`
cannot be misread as tonight, and renders nothing at all for an absent or
unparseable value.
