What problem does it solve? Downstream deliverables like outlines and prose can silently distort, omit, or misrepresent upstream source materials such as domain syntheses and evidence bases. This Skill cross-checks downstream artifacts against upstream pipeline outputs to detect distortions, omissions, and fidelity losses before content reaches publication. ## Core Features & Use Cases - Upstream-to-Downstream Mapping Verification: Explicitly maps where each piece of upstream content appears in the downstream artifact and assesses coverage. - Distortion and Omission Detection: Identifies paraphrasing that changes meaning, flags silently omitted upstream content, and evaluates fidelity against defined standards. - Accuracy Rule Compliance: Enforces 9 Critical Accuracy Rules (ACC-001 through ACC-009) covering terminology, attribution, and methodology correctness, validated by a Python script. - Use Case: After generating a prose section from an outline and domain synthesis, run this verification to produce a YAML report confirming 94%+ of upstream content is represented with no meaning drift. ## Quick Start Verify that my generated prose section faithfully represents the upstream outline and domain synthesis, and produce a TT-09 consistency report in YAML.
