📝 WalkthroughWalkthroughThe pull request adds a review record for all 15 accessibility rules. It documents identified defects, severity decisions, mechanical corrections, test gaps, verified behavior, and out-of-scope items. ChangesAccessibility rule validity review
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🔵 Low · up to The documentation accurately records the review’s purpose but currently includes inconsistent counts, an incorrect Japanese title/translation claim, and a cross-record PR attribution that could mislead maintainers. The PR is mergeable with explicit owner awareness and follow-up because these are bounded documentation issues with no product runtime impact. Possibly related PRs

- Around line 24-26: Reconcile the defect counts in the document: update the
Priority 1 false-positive total to match the rows identified as false positives,
including the duplicate described for row 1, and correct the warning total to
reflect the 15 defined rules with use-list marked info (14 warnings), or
explicitly document any excluded rows.
- Line 112: Update the review record’s PR references so PR `#508` is associated
only with 2026-08-16-ecosystem-smoke-design.md and PR `#510` remains identified as
the out-of-scope --route fix; if the objectives currently assign both fixes
here, correct the objectives rather than adding `#508` to this record.
- Line 92: Update the title-count and translation statements at lines 92 and
109: report 10 English titles and 5 translated titles among the 15 pairs, note
the framing mismatch in the top-level-landmark pair, and limit “faithful
translation” to page content when titles are excluded.

Phase B-4. The a11y category shipped after the 2026-08-09 review of all 73 rules, so it never had that pass. This is it, at the same standard: four parallel reviewers, every web-standards claim verified against a fetched primary source or explicitly labelled unverified, every Svelte claim checked against the Svelte MCP docs, every snippet through
svelte-autofixer, and every detection claim re-run against the builtdist. I independently reproduced the element-level and route-scoped Priority 1 rows.Findings only — fixes are tracked separately, matching the August record's precedent.
Headline
3 of 15 rules carry no Priority 1 defect; 12 do. Materially worse than August's 38-of-73, and the reason is structural: the category's own principle is "false negatives acceptable, false positives not", and ten of the fourteen P1 rows are false positives, clustering in three mechanisms:
aria-query@5.3.2is not the clean ARIA 1.2 snapshot it was taken for — it is mixed (1.2's 48 attributes plus three 1.3 additions), and misses five roles and two attributes browsers already ship. Three P1 rows come from this alone. The roadmap already lists the data-source decision as a pre-1.0 dependency question; this is the evidence for it.accessible-nameaccepts any expression foraria-labelbut only a literal foralt, so<img alt={siteName}>inside a link is "unnamed" — the rule contradicts its own principle inside one function.<slot />,<svelte:fragment />and form-associated custom elements are read as empty content rather than content the analyzer cannot see — the distinction those same functions already draw correctly for components.The two sharpest rows
The docs promise something the engine cannot deliver, verbatim in en and ja: "so mutually exclusive branches never fire a false duplicate". Exclusivity is syntactic only —
{:else if}chains fold into one group, but two adjacent guards do not, so this reportsDuplicate main landmark (2 of 2):{#if data.loggedIn}<main>A</main>{/if} {#if !data.loggedIn}<main>B</main>{/if}A bare
<aside>is not a landmark in either mode, sotop-level-landmark's flagship scenario is undetectable in the markup people actually write — and the docs'<aside role="complementary">example is flagged by Svelte's owna11y_no_redundant_roles.Also recorded
Priority 2 holds ten maintainer calls, including two severity questions where the evidence is weaker than the
warningimplies (require-datetime's a11y rationale is simply false — screen readers read "last Tuesday" fine; the loss is to machines — anddoctype's a11y half is unsourced while being the most expensive single a11y finding in the model, since project scope means a flat 5 points regardless of project size).Priority 3 holds the mechanical corrections, the largest being "Checked by static (CLI) analysis" false on all ten component-scoped pages in both languages — the same leftover class August found for the image rules.
"Recorded, no action" is deliberately substantial: the branch fold and the open/closed-world split — the category's central design claim — were verified sound against six world-poisons, and the kitchen-sink samples all exercise their intended arm. Those should not be re-litigated.
Found outside scope, already fixed
#510 —

(#508, the<style lang="scss">crash, belongs to Phase B-3 and is recorded in the ecosystem-smoke design, not here.)Separately confirmed while here: the roadmap's "remaining P2 items after #428" list is stale — all five (single-h1 wording, hreflang x-default framing, the three correctness message-mechanics corrections) are already resolved in the code.
