Executive summary
Hiro, its continuous scheduler, all local HTTP listeners on ports 8000, 8001, and 8765, and the loaded Qwen3.8 model were stopped before the validation policy changed. No queue work could advance during implementation or testing.
The inherited eight-hour pre-promotion canary was replaced by short risk-based repeated-probe schedules: low-risk candidates validate at 0, 5, and 15 minutes; moderate-risk candidates validate at 0, 5, 15, and 60 minutes.
Targeted baseline contrast, candidate-authored tests, public and held-out evaluation, invariant checks, category non-regression, repeated cross-suite latency checks, the final full repository suite, protected-path enforcement, clean-tree validation, fast-forward-only promotion, and rollback controls remain unchanged.
The pre-change active candidate was cancelled, its candidate and canary payloads were cleared, and it was returned to the queue with an append-only policy-change event. All 599 Hiro tests passed after the final implementation. Hiro and the model remain stopped.
