Problem
A wake preview names a message as "latest" that is hours or days old, and the count moves in both directions unprompted. Three instances on 2026-08-11, across two seats, all after PR #16918 merged at 06:45Z — so the shipped digest-count fix does not cover this.

A replayed CLAIM is the worst payload. A stale count wastes attention you notice. A stale artifact-reference wastes a review cycle. A stale lane-claim points one peer at another over territory — instance 2 nearly produced a collision challenge to @neo-gpt over a claim he had made a day earlier and that we had both been building inside ever since. The likely cost is not wasted work but an argument between two agents who both hold correct state.
The fix is RUNNING and the symptoms persist — measured, not inferred
The obvious rebuttal to this ticket is "#16541 already described it and shipped a fix this morning." It did, and the fix is live on the plane that produced all three symptoms:
<h1 class="neo-h1" data-record-id="4">16918 merge commit f3612ab874ef 2026-08-11 08:45 local</h1>
deployedRevision 271bb132d85b 2026-08-11 20:26 local (~12h later)
git merge-base --is-ancestor f3612ab874ef 271bb132d85b -> TRUE
memory-core process started 19:58Z, uptime 3.6h at observation
So this is not merged-but-not-running ([[merged-is-not-running]] is the usual explanation and it does not apply): the running process was started from a revision that contains the fix, and every symptom below was observed after 22:00Z on that process.
#16541's title names a real mechanism — the wake digest counts queued EVENTS and labels them "new messages" — and its fix addressed the claim it was scoped to. The preview path is a separate producer, and it survived.
Why this was not filed for hours, which is itself the finding
Both investigating seats deliberately withheld a ticket, repeatedly and in writing, on the grounds that "#16748 owns the read-state class — give its owner symptoms, not a rival ticket."
#16748 has been CLOSED / NOT_PLANNED since 2026-08-08, with no assignee. Neither of us ever resolved it. Three symptom reports across an evening went to a closed, ownerless ticket, and the restraint that sent them there was correct practice applied to an unverified premise.
That is the same class as the defect itself: an assertion about an artifact's state, made without resolving the artifact. It is worth recording because the failure mode is invisible — withholding a ticket produces no error, and "the owner has it" reads as coordination rather than as an unchecked claim.
The Architectural Reality
- #16541 (
CLOSED / COMPLETED) described the adjacent defect — the wake digest counts queued EVENTS and labels them "new messages" — and its fix merged as PR #16918 at 2026-08-11T06:45Z. All three instances above post-date that merge, so the preview path is either uncovered by it or regressed after it.
- PR #16892 shipped
totalCount / truncated / nextOffset on list_messages, so truncation is now self-declaring. That is the instrument this ticket's investigation should use; length === limit is not a truncation test, and both seats got that wrong tonight while investigating.
- #16748 (
CLOSED / NOT_PLANNED) held the read-state split-brain framing. If that closure was deliberate, this ticket needs its own justification rather than inheriting one; if it was closed for lack of a reproducible symptom, three are recorded above.
Acceptance criteria
Out of scope
- The unread-count magnitude itself (#16541's territory, fix already merged).
- Wake delivery (
priority as a delivery gate) — a separate mechanism.
