feat(html): add Nu HTML Checker (vnu) gate (config-driven)#9
Merged
Conversation
…e evidence)
Promotes bd-site's bespoke vnu gate into the kit (epic prx-em8h), matching the
axe-gate pattern: pure parse/evaluate core (unit-tested over synthetic vnu payloads,
no Java) + config-driven CLI + ck-html-validator-gate bin + good/bad fixtures.
Runs vnu (the Nu Html Checker, a self-contained Java jar via vnu-jar — headless, no
browser, no network) --errors-only over a project's built pages and FAILS CLOSED
above $HTML_THRESHOLD (default 0). $HTML_DIST/$HTML_PAGES/$HTML_REPORT configurable;
no site coupling (drops bd-site's data/conformance-evidence.json read). Emits the
`htmlValidator: {errors}` envelope lone's conformance() consumes for html.validator-clean.
Tests: pure parse/threshold logic + a best-effort real-vnu e2e over the fixtures
(bad=1 error, good=clean; tolerated skip when no JRE). node test/run.mjs → 15/0.

…mance evidence) (#10) Third and final gate-promotion (epic prx-em8h). Promotes bd-site's bespoke baseline gate into the kit, same pattern as vuln (#7), vnu (#9), axe (#6). Maps the SHIPPED CSS to web-features Baseline data via stylelint-plugin-use-baseline (headless, no browser) and FAILS CLOSED when the site-wide status is below target. HONEST: reports the MEASURED status (widely/newly/limited = the worst feature used); a feature guarded behind an @supports query is a tested fallback and doesn't count. Config-driven ($BASELINE_CSS/$BASELINE_TARGET/$BASELINE_REPORT); no site coupling. Emits the `baseline: {status, fallbackTested}` envelope lone's conformance() consumes for compatibility.baseline. Unlike vnu/axe, the engine (stylelint) is pure npm, so the fixture e2e is DETERMINISTIC and runs in CI (no skip). Tests: pure classify/threshold logic + e2e over good (widely) / bad (:has + ::selection → limited) fixtures. node test/run.mjs → 16/0. With this, all three bd-site gates are reusable in the kit; bd-site can now consume them vendored (prx-v5ry), and the kit is ready to publish (prx-47qm).

What
gates/html-validator-gate.mjs(+ck-html-validator-gatebin): runs vnu (the Nu Html Checker, a self-contained Java jar viavnu-jar— headless, no browser, no network)--errors-onlyover built pages and fails closed above the threshold.parseVnu,evaluateHtml) — unit-tested over synthetic vnu payloads, no Java.$HTML_DIST,$HTML_PAGES,$HTML_THRESHOLD,$HTML_REPORT. No site coupling.htmlValidator: { errors }for lone'shtml.validator-clean.fixtures/html/{good,bad}.html(bad = a<ul>inside<span>, which vnu errors on).Verification
node test/run.mjs→ 15 passed, 0 failed. Pure parse/threshold logic + a best-effort real-vnu e2e (bad=1 error, good=clean; tolerated skip when no JRE, like the axe e2e skips without a browser).Next (prx-em8h)
baseline gate, then bd-site consumes the vendored gates, then publish the kit.
