# ActivityDefinition: Phase 5 Stabilization Daily Check

## Purpose

Scheduled hub-visible health gate for `CUST-WP-0054-T05` during the 72h
stabilization window (2026-07-06 → 2026-07-09). Complements the manual
`tools/phase5-stabilization-check.sh` script with fleet-side evidence in State
Hub progress.

## Trigger

Daily at 09:00 Europe/Berlin while the stabilization window is open. Runs
outside the window are recorded as `skipped` with `reason=outside_stabilization_window`.

## Output Contract

- one State Hub progress event with `event_type: phase5_stabilization_check`
- compact pass/fail detail for health, totals, sweeps, and daily triage freshness
- no LLM call and no direct workplan edits
