What problem does it solve? Changes to EightForge's truth and validation core can silently collapse distinct provenance classes, let stale dependencies pass validation, or desynchronize findings from decisions and execution. This Skill provides a structured expert review lens that catches those violations before they ship. ## Core Features & Use Cases - Authority Classification: Classifies every reviewed path and finding as production authority, compatibility, shadow, design target, or superseded, preventing legacy projections from masquerading as truth sources. - Truth-Record Separation Checks: Verifies that source-derived, derived, human, and effective truth records stay distinct with intact provenance and supersession history. - Validation Freshness and Lifecycle Review: Traces snapshot identities, rule versions, rerun deduplication, finding resolution, suppression, overrides, and downstream decision/execution reconciliation. - Use Case: When a PR modifies lib/projectFacts.ts, validator assembly, or finding closure logic, run this review to confirm compatibility fallbacks cannot hide stale inputs and that findings drive execution through idempotent reconciliation. ## Quick Start Review this pull request touching lib/projectFacts.ts and the validation findings lifecycle using the EightForge truth-engine review checklist.
