What problem does it solve? Execution workflows that turn validated decisions into workflow state often drift: duplicate execution items, orphaned outcomes, silent suppression, or UI projections that diverge from server truth. This Skill provides a structured expert review lens to catch those defects before they ship. ## Core Features & Use Cases - Execution Lifecycle Review: Validates execution item states (pending, resolved, suppressed, blocked) against product semantics and the persisted model. - Idempotency & Reconciliation Checks: Ensures outcome, retry, suppression, override, and sync mutations converge safely after duplicate delivery or partial failure. - Authority & Boundary Enforcement: Classifies findings as production authority, compatibility, shadow, or design target, and routes cross-cutting concerns to sibling reviewers (truth engine, audit, UX, Supabase, migration). - Use Case: When reviewing a pull request that adds an outcome endpoint to /api/ execution routes, run this review to verify actor attribution, upstream decision linkage, and consistent operator UI projection. ## Quick Start Review this pull request touching execution outcome routes and sync logic using the EightForge execution reviewer checklist.
