What problem does it solve? Changes to audit logging, activity tracking, and provenance systems can silently break compliance guarantees, lose history, or blur the line between current state and historical events. This Skill provides a structured review process that catches broken event contracts, missing provenance, and immutability violations before they ship. ## Core Features & Use Cases - Audit Contract Review: Classifies every mutation's history obligation as transactionally required, durable/retriable, or best-effort, and verifies failure handling matches that severity. - Provenance and Immutability Checks: Validates source-to-execution lineage, immutable run history, supersession, override, and correction trails without rewriting the past. - Authority Classification: Labels findings as production authority, compatibility, shadow, design target, or superseded to prevent shadow or design artifacts from masquerading as live truth. - Use Case: When a pull request modifies activity_events writes or adds a new decision override flow, invoke this Skill to verify the event contract, identity fields, and rollback behavior produce a complete, reconstructable audit trail. ## Quick Start Review this pull request touching activity_events and decision provenance for audit contract violations and missing history.
