What problem does it solve? Reviewing broad pull requests and architecture changes in the EightForge platform risks missing cross-cutting violations such as parallel authority paths, fabricated source truth, shadow-code leakage, and broken layer boundaries. This Skill applies a consistent umbrella review doctrine so every change is checked against the same architectural invariants. ## Core Features & Use Cases - Authority Classification: Classifies every reviewed path and finding as PRODUCTION AUTHORITY, PRODUCTION COMPATIBILITY, SHADOW IMPLEMENTED, DESIGN TARGET, or SUPERSEDED/REJECTED. - Architecture Checklist: Enforces one-way Extraction-to-Audit flow, truth-record separation, shadow isolation, compatibility containment, and minimal-diff scope. - Structured Verdict Output: Produces a fixed report format with verdict, severity-ordered key issues, minimal fixes, regression risks, suggested tests, and one positive note. - Use Case: When reviewing a full PR that touches validation, document pipelines, and project-facing projections, use this Skill to trace writers, consumers, and fallbacks, then route domain-specific checks to the specialized EightForge reviewers. ## Quick Start Review this pull request for EightForge architecture violations and produce a verdict with severity-ordered issues and minimal fixes.
