QA (Quality Assurance) persona orchestrator. Runs audit-test-coverage and audit-security-and-governance in parallel inside an isolated git worktree, synthesises findings tagged [Confidence: Level] / [Risk: Level], then spawns remediate-test-coverage or create-bug-report subagents with clean context in a developer decision loop. Scope calibrated by mode: Delta (post-change: the change + its Seams, adversarial edge cases) or Release-gate (full-surface regression sweep anchored to the resolved target test surface). Working tree never touched.
