Add activity_core/state_hub_write: every State Hub write (report-sink, ops-evidence, schedule-miss) now sends a stable Idempotency-Key header derived from run_id:instruction_id:event_type. Makes writes safe to buffer/replay under the future state-hub beachhead without duplicate progress/triage events. The read-based _progress_exists dedup is now best-effort (returns False on connection error instead of hard-failing), so the guarantee lives on the keyed write rather than a live read. Tests + runbook note. Endpoint adoption / proxy retirement stays blocked on the state-hub beachhead capability. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> |
