ActivityDefinition: Phase 5 Stabilization Closeout Check

Purpose

One-shot closeout gate at the end of the CUST-WP-0054-T05 stabilization window. Fails visibly when hub-visible gates are not green. When gates pass, records operator_signoff_needed: true for coulombcore teardown approval.

Trigger

Scheduled once at 2026-07-09T17:35:00Z (72h after window open).

Output Contract

• one State Hub progress event with event_type: phase5_stabilization_closeout
• fails the ActivityRun when any gate is red at closeout time
• no LLM call and no direct workplan edits
