Use when a multi-slice phase has been implemented and the operator wants an independent audit of ALL slices before sign-off, or asks to "audit the phase", "review all slices", "independent check". Spawns a fresh sub-agent that examines every slice against the spec. Do NOT use for a single-diff review (use code-review), for security-only review (use security-permissions-review), or before a phase is implemented.
