Deliverables

Spec: docs/specs/2026-08-20-evidence-results-review-brief.md — intent, AC-1..AC-5, non-goals, clipboard-only decision recorded
Code: buildReviewBrief in compare-model.ts; “Copy review brief” button with clipboard fallback + inline status in CompareView.tsx; styles in shell.css; package in index.ts
Tests: 3 new cases in compare-model.test.ts (full Markdown contract, zero-cost wording, insufficient-pairs wording)

Verification evidence

121 package tests passing, tsc --noEmit clean
Browser end-to-end against fixture evidence: the exact Markdown brief reached the clipboard (verified character-for-character), both the “Copied” and “Clipboard unavailable” states confirmed, wide/narrow screenshots captured, no console errors beyond the pre-existing favicon 404

Next step: push the branch and open a PR against main — want me to?
