Skill activation triggers

Run Debug before any patch when the failure is unexplained. Run Observability when the only reliable repro is production-shaped. Run Testing as soon as a hypothesis is confirmed so the fix cannot regress silently.

Verification that skills worked

• At least two ranked hypotheses existed before the first patch
• Fix is verified in the failing environment, not only locally
• A regression test or monitor would fail on the pre-fix behavior

Changelog

• 1.3 (2026-07-29): Debug skill activation and verification rewritten for this envelope.
