feat(kanban): stamp handoff freshness so workers don't read stale state as current - #53973
Merged
Conversation
…te as current Multi-agent boards leak staleness: a sibling worker's parent handoff, comment, or prior-attempt summary gets read by the next worker as live truth even when it's a day old. build_worker_context surfaced the text with (at best) a bare absolute timestamp, which an LLM reads as fact regardless of age — parent results had no timestamp at all. Adds a coarse relative-age stamp (just now / 18h ago / 3d ago) to every recalled-state line and a one-line 'point-in-time snapshot, re-verify against source' frame on the parent-results section, so the worker sees when handoffs were produced and re-checks stale ones before acting.

Summary
Kanban workers now see when a handoff was produced, so a sibling's day-old parent result / comment / report stops being read as live truth.
On multi-agent boards (orchestrator + kanban + multiple workers),
build_worker_contextsurfaced recalled state — parent task results, the comment thread, prior attempts, role history — with at best a bare absolute timestamp. An LLM reads "2026-06-25 14:30" as fact regardless of how old it is, and parent results carried no timestamp at all. So a worker picking up a "quick change" the next day acts on stale state as if it's current.Changes
