Golden frames carried the card version text (about, version banner, support/export previews), so every beta bump re-accepted up to 20 baselines that had not visually changed. The version now reaches the DOM and stand requests through displayVersion() (src/card-version.ts); the golden harness pins window.__HP_VERSION_OVERRIDE__ = '0.0.0-golden' before the card is created. CARD_VERSION literals stay where the release contract reads them; cache-busting and the console banner keep the literal. Docs screenshots: `npm run docs:accept -- --identical` re-captures locally, compares decoded RGBA pixels with the committed frames inside Chromium (scripts/png-identical.mjs) and, only when every frame is identical, refreshes the manifest fingerprints and captureScriptSha256; bytes stay, any difference refuses with a per-frame count. First run on this tree: 11/11 identical, manifest refreshed. Mutants: version-seam-ignores-override, docs-identical-accepts-any-frame. Issue: #512 User-Visible: no
