# M6 — expanded axe ruleset (#1668)

**Closes #1668.** M1-M5 already merged: M2 palette/contrast, M3
typography, M4 per-route polish, M5 axe gate + 443→0 fixes.

## What this PR adds

### Expanded axe ruleset
- New rules: image-alt, label, aria-required-attr, aria-valid-attr (12
total, verified 0 violations on master after one fix)
- Mobile viewport (375×812) added alongside existing 1200×900 desktop
- TDD: RED commit `d3e4309e` expands the rule/viewport set deliberately
to fail; GREEN commit `5599068f` adds the one needed aria-label fix on
audio-lab BPM + Volume sliders

## What this PR does NOT include

The letsmesh A/B verification artifact (initially scoped for M6) is
split out to a follow-up issue. The capture script needs more work to
reliably navigate post-onboarding state on both sites. Tracked
separately so the gate-expansion work isn't held up by tooling.

## Test plan
- `test-a11y-axe-1668.js` runs new ruleset across both viewports — 0
violations baseline (on master pre-merge AND post-merge)
- `test-a11y-axe-1668-selftest.js` unchanged (allowlist semantics still
apply)
- Anti-tautology: reverting `5599068f` produces 8 net violations on
`#alabBPM`/`#alabVol` × 2 themes × 2 viewports

## Notes
- Allowlist still empty (per M5 policy — issue# + expires_at required)
- M5 token work covered all color-contrast surfaces; M6's image/aria
additions only required one fix (audio-lab sliders)
