Reports

Five formats plus a manifest:

• HTML — single <base>.html (success / failure rows in one document).

• JSON — split <base>_success.json + <base>_failure.json.

• XML — split <base>_success.xml + <base>_failure.xml.

• JUnit XML — single <base>_junit.xml (CI-native).

• Allure — directory of <uuid>-result.json files (Allure CLI input).

generate_all_reports(base, allure_dir=None) runs every generator and writes <base>.manifest.json mapping each format to the actual paths produced — downstream CI globs no longer need format-specific knowledge.

Reporting & CI extras

• pr_comment.post_or_update_comment(repo, pr_number, body, token=) — idempotent via a hidden HTML marker.

• trend_dashboard.compute_trend("ledger.json") + render_html(trend) — daily pass-rate / duration / SVG chart.

CI reproducibility & long-term observability

• workspace_lock.build_lock(drivers=..., playwright_versions={"chromium": "127.0.0.0"}) — snapshots every Python distribution + driver + Playwright browser version; write_lock / diff_locks round-trip.

• a11y_trend.aggregate_history(history) + render_html(points) — per-day per-impact axe-violation count, self-contained SVG chart.

• perf_drift.detect_drift({"lcp_ms": samples}, baseline_window=20, recent_window=5, tolerance=0.1) — sliding-window P95 drift detection; assert_no_regression(report) is the strict path.
