Run a Quick QA test on ${testServer.url}/qa-only.html
This fixture has one static homepage, one console error, no links or user journeys, and no test framework. Its index.html is an exact copy of the served page. Scope this run to homepage load and console health; do not expand into navigation, form, visual-design or framework-discovery audits.
Write one concise charter and a concise report, retaining required evidence, scores and untested-coverage fields. Use short factual summaries and evidence IDs instead of repeating full commands or the charter in multiple sections.
Use the supplied read-only browser probe for the baseline and any replay, as this child command after the guard's --: bash -c 'bun "${path.join(qaOnlyDir, 'fixture-browser-probe.ts')}" "${browseBin}" "${testServer.url}/qa-only.html" "${path.join(qaOnlyDir, 'qa-reports/screenshots/initial.png')}"'
Run it inside the deadline guard. It navigates, reads console errors and saves the screenshot, returning one JSON object with actual command outputs and exit codes. Preserve that decoded object in checkpoints. This case tests report-only authority and provenance; terminal-text framing is covered separately by deterministic regressions.
For a replay, pass a fresh screenshot filename in the same screenshots directory; the probe refuses to overwrite earlier evidence.
Do NOT use AskUserQuestion — run Quick tier directly.
Use ${qaOnlyDir}/qa-reports as the caller-owned directory for all reports, checkpoints and screenshots.
