Subject: [PATCH] docs: record the a11y tail, and four names written where
 nothing reads
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Phase 3 shipped in six landings and a11y.md is closed, which closes all
four audits from 2026-08-11.

The pass's one lesson is that an accessible name is computed on the
element carrying the role, and every tier we check with looks somewhere
else: the audit read the source and credited a name that was never
computed, an AX sweep read the tree and reported a placeholder-only box
as clean, and a component test asserted the attribute and pinned the
bug it existed to prevent.

Six of the audit's claims turned out to be wrong or smaller than
written, and one of the plan's own findings was false — the page
header's sort control is named on all nine views. All of them are
written down, which is where a third of the value of the last two plans
came from.

+
+Plan 008 phase 3: the tail of `a11y.md`, which closes it — and with it
+all four audits from 2026-08-11.
+
+The generalisation, and it is the whole of this pass: **an accessible
+name is computed on the element carrying the role, and every way we
+have of checking one looks somewhere else.** The audit read the
+*source* and credited a name that was never computed. My AX sweep read
+the *tree* and reported a weak name as no problem. A component test
+asserted the *attribute* and pinned the bug it was written to prevent.
+Three tiers, three different wrong answers, all about the same
+property.
+
+Concretely, and each of these is a finding:
+
+| where it was written | where the role is | computed name |
+|---|---|---|
+| `aria-label` on `<wa-slider>` | a div in its shadow root, `aria-labelledby="label"` | `""` |
+| `<label>` beside a `<select>` in `config-field` | the select | `""` |
+| `placeholder` on Explore's search input | the input | the placeholder |
+| `label` on `<wa-progress-bar>` | inner div's `aria-label` | correct |
+
+The first is `wa-dialog`'s trap one component over and cost two
+sessions in 007. The fix is different, though, and the difference is
+worth keeping: `wa-progress-bar`'s `label` *is* an `aria-label` and is
+invisible, so it is just the right API; `wa-slider`'s `label` is
+**visible**, so the name comes from the library's own property and
+`styles/wa-slider-label.css.ts` hides it by part. That is preferred
+over `name-dialog.ts`'s reach into the shadow root for one reason —
+if Web Awesome renames the part, the label becomes *visible* and
+correctly named, rather than silently nameless again. Choose the
+failure you would rather have.
+
+Nine more things worth keeping:
+
+- **A sweep for empty names cannot see a weak one.** A `placeholder`
+  is an accname fallback, so `getFullAXTree` reported the whole Explore
+  view *clean* — which is why `a11y.26` survived four phases of people
+  looking for exactly this class of bug. "0 unnamed" answers a
+  narrower question than it reads as, which is the third time in this
+  plan a *count* has done that.
+- **The count that sent Phase 1 hunting was wrong in both halves.**
+  "Two unnamed native `<select>`s, one of them the page header's sort
+  control on nine views": the sort control is named `Sort: ` by its
+  wrapping `<label>` (`from: relatedElement`) on all nine, and the two
+  unnamed roles were one `config-field` select and the *seek bar*.
+  Recorded as a finding in the plan, believed for a phase, false.
+- **…and the thing it was pointing at was nine times bigger.** With
+  Settings' sections expanded: **24 of 93 controls unnamed**, every
+  `config-field` select and toggle and all eighteen column checkboxes.
+  No finding names it, and `a11y.6` is not wrong — it says in its own
+  line that it scanned every `<button>`. Same shape as phase 2's
+  contrast number.
+- **A fix's own test can be pinning the bug.** `transport.test.ts`
+  asserted `aria-label` on the `wa-slider` host under the title
+  "carries an accessible name". It passed for six phases. *Run the
+  existing tests* found it — third plan running that this is the rule
+  that pays.
+- **`a11y.21`'s mechanism does not exist, and the real one is on the
+  other axis.** "The 4em bars grow while the viewport does not and
+  anything that no longer fits is clipped" — the middle grid row is
+  `1fr` and absorbs them exactly: at 200% text on 800×600 the bars go
+  64 → 128px, the panel 472 → 344px, and the footer still lands on 600.
+  Nothing is clipped vertically. Horizontally the shell is 784px inside
+  a 320px viewport (400% page zoom, the width 1.4.10 names) with 464px
+  of it behind `overflow: hidden`. Measure the axis the finding does
+  not mention.
+- **`overflow: hidden` still permits programmatic scrolling**, so
+  `scrollLeft = 9999` returns a healthy 464 on the build that has the
+  bug. My first spec passed against the broken build for that reason.
+  A wheel gesture is the probe. Fifth entry in this plan's "the probe
+  was wrong, not the code" column, and the tell was the oldest one
+  there is: **it could not fail.**
+- **A synthetic `MouseEvent` does not reach a delegated handler.**
+  Three probes in a row reported a queue row as never becoming active;
+  `getByTestId('queue-row').dblclick()` made it active immediately.
+  Delegation reads things a hand-built event does not carry.
+- **A finding can be half-closed by a phase that was not about it,
+  and the half that remains is smaller than the sentence.** `a11y.34`
+  reads "the sort direction is a 10px glyph *or nothing*" — Phase 1's
+  `aria-sort` closed the *or nothing*, leaving one declaration. Second
+  time in this plan (`a11y.11` was the first), and both times reading
+  the sentence rather than the residue would have built something that
+  already existed.
+- **The state a fix lands in, again, and it was three pixels.**
+  `a11y.29` takes the subtitle's bottom margin away with the `<h3>`,
+  which *shortens* the flex-centred title block and moves it **down**
+  into the bar's clip — the hgroup had measured 67px inside a 64px bar
+  since before any of this, and the descenders of "meant to bee." were
+  cut. Found by reading a screenshot of the fix, which is the fifth
+  regression in three plans that only a PNG has caught.
+
+And one thing that went right and is worth copying: **the marker for
+`a11y.22` is a shape drawn in padding the row already had.** The track
+list's grid columns are computed from the host width, so anything in
+the flow moves every cell on the playing row and nothing else. A
+`::before` triangle in the 8px left padding costs no layout, and both
+tiers assert it is *absent* on the other rows — a marker that renders
+everywhere satisfies "the playing row has one" for free.

+
+#### Where the plan was wrong — Phase 3
+
+Ten things. The first four are the audit or the plan being wrong about
+where a control's name lives.
+
+- **The two unnamed `<select>`s from Phase 1 were one `<select>` and a
+  slider, and neither was the page header's.** `page-header`'s sort
+  control computes "Sort: " from its wrapping `<label>`, on every one
+  of the nine views — checked with `getFullAXTree`, `from:
+  relatedElement`. The other unnamed role was the **seek bar**, which
+  `a11y.md` lists under *what is already correct*. Fourth probe error
+  in two passes, and the same shape as the rest: read at the wrong
+  level.
+- **`aria-label` on a Web Awesome host does not name the control.**
+  `wa-slider` puts `role="slider"` on a div in its own shadow root
+  pointing `aria-labelledby` at an empty internal `<label>`, and that
+  IDREF outranks the host's `aria-label`. Both sliders computed `""`.
+  Exactly `wa-dialog`'s trap one component over, and the audit made
+  exactly the same mistake in the opposite direction — it read the
+  source and credited a name that was never computed.
+  `volume-control` did not even have the `aria-label` it is credited
+  with.
+- **`a11y.25` is not "unnamed".** `wa-progress-bar` falls back to the
+  localised word *progress*, so it announced "Progress, 45%" — named
+  after the widget rather than after the work. Same fix, smaller claim.
+- **Settings was full of unnamed controls and no finding says so.** 24
+  of 93. `a11y.6` is not wrong: it says in its own line that it scanned
+  every `<button>`. Third time this pass that a count in the audit was
+  answering a narrower question than it reads as.
+- **A placeholder is an accessible name.** Explore's search box
+  therefore reported *clean* in an AX sweep of all eleven views, which
+  is why `a11y.26` outlived four phases of people looking for exactly
+  this. A sweep for empty names cannot see a weak one.
+- **`a11y.21`'s mechanism does not exist.** "The 4em bars grow while
+  the viewport does not, and anything that no longer fits is clipped
+  with no scrollbar" — the middle row is `1fr` and absorbs them
+  exactly. At 200% text on 800×600 the bars go 64 → 128 and the panel
+  472 → 344, footer still on 600. The real failure is horizontal, which
+  the finding does not mention: 784px of app in a 320px viewport, 464px
+  of it unreachable.
+- **…and the obvious probe for it passes on the broken build.**
+  `overflow: hidden` still permits *programmatic* scrolling, so
+  `scrollLeft = 9999` returns a healthy number on the build with the
+  bug. It did. The spec is a wheel gesture now.
+- **A fix's own test was pinning the bug.** `transport.test.ts`
+  asserted `aria-label` on the `wa-slider` host and called it "carries
+  an accessible name". Running the existing suite is what found it,
+  for the third plan running.
+- **`a11y.34` was half closed by Phase 1 and nobody had noticed.** "The
+  sort direction is a 10px glyph *or nothing*" — it is announced now,
+  via the `aria-sort` Phase 1 added. What was left is one declaration.
+- **The queue's `aria-current` is dead in the common path.** A track
+  started from the *track list* leaves the queue's `currentIndex` at
+  −1, so the panel has no current row at all — which is why `22`'s
+  marker looked broken the first time it was checked in the running
+  app. Pre-existing, not fixed here, and the reason the e2e case plays
+  from the queue.
+
+And one that is about the harness rather than the audit: **a synthetic
+`MouseEvent` does not reach a delegated handler the way a real gesture
+does.** Three probes in a row reported the queue row as never becoming
+active; `page.getByTestId('queue-row').dblclick()` made it active
+immediately. Same family as everything above — the probe was wrong, not
+the code.

+The name comes from `label` now, the library's own API, and
+`styles/wa-slider-label.css.ts` hides it: preferred over reaching into
+the shadow root the way `name-dialog.ts` must, because if Web Awesome
+renames the part the label becomes *visible and correctly named*
+rather than silently nameless. Its second rule is load-bearing —
+`#slider` takes an 8px margin the moment a label exists, which grows
+the bar 6px → 14px and moves the transport with it.
+`wa-progress-bar`'s `label` *is* an `aria-label` and is invisible, so
+there it is just the right attribute.
+
+The same thing in the light DOM: `config-field` rendered a `<label>`
+as a **sibling** with no `for`, so **24 of 93 controls on Settings**
+computed an empty name. They use `for`/`id` (a fixed id, safe only
+because each field is its own shadow root) rather than `aria-label`,
+for what it buys beyond the name — the label text becomes a click
+target. And three surfaces are named but identify nothing, which is
+the same fault one step milder: three shortcut buttons announced
+themselves as "S", thirty-six column arrows as "Move up", and every
+queue row's remove button as "Remove from queue".
+
+**Checking any of this needs the browser's own answer, and "0 unnamed"
+is not it.** A `placeholder` is an accname fallback, so an
+`Accessibility.getFullAXTree` sweep of all eleven views reported
+Explore's search box — the audit's own `a11y.26` — as clean. A sweep

+lands on 600. Horizontally the shell is 784px inside a 320px viewport
+(400% page zoom, the width WCAG 1.4.10 names) and 464px of it,
+including the job indicator and the queue button, used to sit behind
+`overflow: hidden`. Keeping the vertical axis fixed is what keeps the

+`scrollLeft` passes on the broken build; the spec uses a wheel gesture.

+**The playing row is a shape, not a hue.** `track-list` and
+`queue-panel` draw a `::before` triangle in each row's own left
+padding, plus `aria-current` — before, both rows were a background tint
+and a text colour and nothing else (WCAG 1.4.1). It is in the padding
+because the track list's grid columns are computed from the host width,
+so a marker in the flow moves every cell on the playing row and nothing
+else. Both tiers assert it is **absent** on the other rows: a marker
+that renders everywhere satisfies "the playing row has one" for free.
+One thing to know before checking it — a track started from the *track
+list* leaves the queue's `currentIndex` at −1, so the panel has no
+current row at all in that flow, which reads exactly like the marker
+not working.
+
+**The first thing Tab reaches is a skip link.** Two details are
+load-bearing and neither is the link's text. It is `position: absolute`
+in **both** states, because `body` is a grid with named areas and an
+in-flow extra child is auto-placed into one of them. And `<main>`
+carries `tabindex="-1"`, or the fragment moves the scroll, leaves the
+tab sequence exactly where it was, and looks like it worked. The
+subtitle beside it is a `<p>`, which is also what an `hgroup` is
+supposed to contain — and dropping the `<h3>`'s bottom margin shortened
+the flex-centred title block enough to move it down into the 4em bar's
+clip, so `.title` zeroes both margins.

 **A selectable grid is a listbox.** The four grids that ctrl/shift-select
 (`artists-view`, `genres-view`, `cover-grid`, and the queue) are
 `role="listbox" aria-multiselectable` over `role="option"` cards, not
