+# Final visual and comprehension QA
+
+## Conclusion
+
+SINGLE_OPERATOR_QA was executed on 2026-08-09 against exact candidate
+`1842769004c044efa9e4414aa1c2df1ca0123629`.
+
+Conclusion: PASS
+
+Findings: P0 `0`, P1 `0`, P2 `0`.
+
+No independent second reviewer is claimed. The maintainer performed the
+implementation-separated visual/product QA required by the current
+single-operator workflow.
+
+## Candidate and method
+
+- Repository: <https://github.com/OriginShift/AnteSig>
+- Exact checkout: `1842769004c044efa9e4414aa1c2df1ca0123629`
+- Deployed RC: <https://antesig.vercel.app>
+- Node.js: `v22.23.1`
+- pnpm: `11.16.0`
+- Runtime profile: `CLEAR402_ENABLED=false`
+
+The application was built and served from the exact local checkout. Browser
+screenshots were captured from that production build, not from a prior build or
+an unrelated URL. Dynamic run IDs were replaced with the stable
+`run_redacted-for-stable-qa` marker before capture; no other visible evidence
+was changed.
+
+## Fixed viewports
+
+| Viewport | Scenario | Screenshot | Result |
+| --- | --- | --- | --- |
+| 1440x900 | Happy path | [`visual-1440x900-happy.png`](../artifacts/screenshots/visual-1440x900-happy.png) | PASS |
+| 1280x720 | Amount mismatch | [`visual-1280x720-stop.png`](../artifacts/screenshots/visual-1280x720-stop.png) | PASS |
+| 390x844 | Happy path | [`visual-390x844-happy.png`](../artifacts/screenshots/visual-390x844-happy.png) | PASS |
+| 360x800 | Amount mismatch | [`visual-360x800-stop.png`](../artifacts/screenshots/visual-360x800-stop.png) | PASS |
+
+Each screenshot retains the complete page so reviewers can inspect the first
+result viewport and the long-form evidence below it.
+
+## Automated evidence
+
+`pnpm test:e2e --grep 'visual|responsive'` passed against the production server:
+8 tests passed and 2 Clear402-enabled-only tests were skipped as required by
+the disabled runtime profile. The matched suite covered desktop/mobile happy
+and STOP paths, accessible controls, loading stability, disabled-profile
+isolation, and explicit Live-failure recovery.
+
+An additional exact-candidate Playwright audit covered all four fixed
+viewports. Every viewport reported:
+
+- document width equal to viewport width;
+- zero horizontally out-of-bounds visible elements;
+- zero clipped buttons, inputs, textareas, or selects;
+- zero overlaps between adjacent result sections;
+- zero fixed or sticky control occlusions;
+- response provenance within the first viewport of the result pane; and
+- zero browser console errors and zero uncaught page errors.
+
+## Acceptance review
+
+| Requirement | Result | Evidence |
+| --- | --- | --- |
+| No overlap, clipping, or horizontal scroll | PASS | DOM geometry audit and four screenshot inspections |
+| No text hidden behind fixed controls | PASS | Zero fixed/sticky occlusions |
+| Amount mismatch understandable without raw JSON | PASS | Intent and prepared amounts plus critical Alignment failure are visible in the comparison and STOP sections |
+| Status is not color-only | PASS | `MANUAL_REVIEW`, `STOP`, `FAIL`, icons, headings, and reason text remain visible |
+| Provenance in result and exported evidence boundary | PASS | `Response source FIXTURE` is in the result header; result facts and raw evidence exports retain `FIXTURE` |
+| `MANUAL_REVIEW` is not green approval | PASS | Amber presentation explicitly says human review remains required and this is not approval or authorization |
+| STOP action boundary is visible | PASS | Red STOP banner shows `DO_NOT_PROCEED_TO_SIGNER` without opening raw JSON |
+| Long address, reason, and reference text fits | PASS | 360px audit has no overflow or clipped control and screenshot inspection confirms wrapping |
+| Loading, error, and result states are stable | PASS | Responsive suite covered stable loading width, Live error isolation, and explicit Fixture recovery |
+| Core result is understandable in 20 seconds | PASS | Maintainer timed comprehension check identified request, prepared capability, observed simulation, provenance, and the final action boundary from the result header and three-way comparison |
+| Screenshots belong to exact candidate | PASS | Built and captured from exact checkout; candidate SHA and commands recorded above |
+
+The 20-second check is a bounded maintainer comprehension check, not a claim of
+an independent user study. The visible summary supports this reading without
+requiring the raw JSON drawers.
+
+## Release impact
+
+No product code or test source was changed during this QA task. No P0/P1 defect
+blocks the M5 release-candidate freeze.
