What problem does it solve? When contracts, amendments, exhibits, rate schedules, and invoices interact, it is hard to verify that code changes correctly determine which document governs, which modifies, and which conflicts. This Skill provides a structured review checklist that keeps cross-document reasoning deterministic, evidence-anchored, and auditable. ## Core Features & Use Cases - Relationship Semantics Review: Verifies that attached_to, supplements, modifies, and replaces keep distinct semantics across governing families, amendments, and exhibits. - Precedence and Authority Classification: Classifies findings as PRODUCTION AUTHORITY, PRODUCTION COMPATIBILITY, SHADOW IMPLEMENTED, DESIGN TARGET, or SUPERSEDED/REJECTED, and ensures unresolved precedence stays unresolved rather than falling back to a fabricated answer. - Provenance-Preserving Selection: Checks that governing selections retain competing records, effective-time basis, and operator-readable explanations. - Use Case: When reviewing a pull request that changes how amendments propagate to rate schedules, use this Skill to trace the six-stage resolution sequence and produce a verdict with severity-ordered issues and minimal fixes. ## Quick Start Ask the reviewer to evaluate your pull request affecting document relationships or governing contract selection using the eightforge-cross-document-reviewer checklist.
