feat(replication): expose connection-truth liveness age in cluster_status (#431)#524
Merged
Conversation
…atus (#431) cluster_status already reports the shared-memory connection truth (connected override + lastConnectionError, from #445). Add the missing piece: lastLiveness, the wall-clock of the link's last proof-of-life (handshake/pong/receive stamp). Operators — and the W1 watchdog-demotion soak — need to see how fresh the truth behind `connected` is, distinguishing an actively-alive link from one nearing the staleness window.

Code Review
This pull request updates the replication/clusterStatus.ts file to surface the last proof-of-life timestamp (lastLiveness) on the socket object when reading connection truth. This allows operators and watchdogs to assess the freshness of the connection state. There are no review comments, and I have no additional feedback to provide.

What
One-field addition to
cluster_status(W1 / #431, W8 Tier-1 overlap):socket.lastLiveness— the wall-clock of the link's last proof-of-life (handshake/pong/receive stamp from the shared-memory truth slots #445 added).cluster_statusalready reports the truth-derivedconnectedoverride andlastConnectionError; liveness age was the missing piece. Operators — and the W1 watchdog-demotion soak (design on #431) — need to see how fresh the truth behindconnectedis: an actively-alive link vs one coasting toward theLIVENESS_STALE_MSwindow reads identically today.Same
asDateformatting as the neighboring fields; a never-alive link omits the field (asDate(0)→undefined), matching house style.Notes
Part of #430 · W1 #431 · follows #445.
