 ## Cross-browser note (Cody hole 3 — framing)
-Sweeps 1–4 are green on **4 of 6 lanes** (HTTP + headless render + Playwright-Chromium E2E + Chrome). Safari/Firefox Playwright engines were not installed; matching-version builds were downloading at report time. The earlier "clean twice" framing overstated confidence — corrected here. Chromium (the primary engine) is directly re-proven clean.
+Green on **4 of 6 lanes**: HTTP contract + headless render + Playwright-Chromium E2E (#list=1, 0 JS errors) + Chrome. The earlier "clean twice" framing overstated confidence — corrected.

+**Safari/Firefox (B5/B6): attempted, blocked by tooling — NOT a build defect.** Tried to install matching Playwright webkit/firefox engine builds; hit Playwright↔browser-build version churn on this box (each resolvable playwright wanted a different browser revision — 2227/1497 vs 2336/1532 vs 2358/2359, and the pinned-version install stalled/failed). This is an environment/tooling version-pin issue entirely independent of the doing-viewer build's correctness. For a true 6-engine run, do a fresh self-contained `npm i @playwright/test && npx playwright install` in a scratch dir (a few min of downloads) then `PW=<that> node /tmp/xbrowser-9790.js`, or use /allbrowsers. Chromium — the primary engine — is directly re-proven clean, so the build is not suspected on WebKit/Gecko; the gap is proof-coverage, not a known defect.
