Accessibility Audit Plugin v1.7.0

Audit-quality contract release

This release makes AUDIT_QUALITY_CONTRACT.md the normative product and release contract for the public accessibility audit plugin.

What changed

• Accounts for every WCAG 2.2 Level A and AA success criterion with explicit automated, guided, manual, not-applicable, or blocked status.
• Applies one central confidence gate before any issue can be labelled a confirmed failure; uncertainty remains a review candidate or coverage blocker.
• Strengthens contrast, overlap, visibility, applicability, repeatability, evidence, and deterministic deduplication checks to reduce false positives and inflated counts.
• Captures keyboard journeys, interactions, 320 px reflow, 200% text resize, WCAG text spacing, and native NVDA/VoiceOver evidence without presenting synthetic DOM inspection as screen-reader proof.
• Keeps canonical JSON, accessible HTML, validated XLSX, screenshots, and evidence records aligned.
• Adds executable contract, adversarial, fresh-consumer Action, package, native assistive-technology, and exact two-run BuggyLand release gates.

Verified baseline

The public BuggyLand regression was identical across two complete runs: 31 confirmed failures, 36 review candidates, 1 blocker, 68 consolidated findings, 55 A/AA manual procedures, and 485 evidence records.

Honest conformance boundary

This tool provides complete WCAG 2.2 A/AA accountability and evidence-led pre-audit support. It does not claim that automation alone certifies conformance. Criteria requiring human judgement remain unresolved until a qualified reviewer records evidence and a verdict.

See the Audit Quality Master Contract for the authoritative requirements and acceptance gates.
