TestsThe two new tests cover the fix well, including the nested-anchor row shape, and the Checks I ran

WDiv auto-wraps into a WAnchor whenever its className carries `hover:`,
`focus:` or `active:`, purely to get the state WAnchor tracks. WAnchor
published `Semantics(button: true)` unconditionally, so that styling wrap
became a claim the widget cannot keep.
Measured on `WDiv(className: 'px-4 py-3 hover:bg-slate-100', child:
WText('Latency'))`: one button node labelled "Latency" whose action set
was `focus` alone, with no `tap`. A screen reader offers it as a button,
the user activates it, and nothing happens, because there is no gesture
in the tree to run. After the change the same card keeps its "Latency"
label and loses the role.
A gestureless anchor now publishes no node of its own and lets its
descendants speak. An anchor with onTap, onLongPress or onDoubleTap is
untouched, so WButton and every real control keep their single named
button node with its tap action, and an explicit semanticLabel still
wins for the icon-only case that has no child text to merge.
One claim retired rather than shipped: the nesting `WAnchor(onTap:) >
WDiv(hover:...)` did NOT announce twice. It did put two button nodes in
the widget tree, which is what an earlier reading counted, but the inner
one carried `isMergedIntoParent`, so Flutter folded it into the real tap
surface and never sent it to the platform. The test helper now filters
merged nodes, and the test for that shape is labelled a regression guard
rather than a reproducer: it passes both with and without the fix.
The two gestureless tests fail with the guard disabled and pass with it.
Full suite 1700 green at 94.8% coverage.

The "Open, not yet fixed" section outlived all three of its entries. F6 closed in #85 (wall-clock rotation boundaries) and the unlabelled shell controls in #83 (ShellControlSemantics). The third entry was half right and its load-bearing half was wrong. Real: WDiv auto-wraps into a gestureless WAnchor for hover state and WAnchor published a button role regardless, so a decorative hoverable card was offered as a control whose entire action set was `focus`, with no tap behind it. Fixed upstream in fluttersdk/wind#182. Not real: the double announcement. That shape put two button nodes in the WIDGET tree, which is what the original reading counted, but the inner one carried `isMergedIntoParent`, so Flutter folded it into the real tap surface and never sent it to the platform. F19 had already reached that conclusion from the DOM side and said so. The open list kept the claim anyway, which is the point of recording this: a retraction in one place and not the other is how a corrected finding gets re-fixed. The nameless-control half was real and larger than first thought: MSPageHeader's back control was unnamed on every detail page (fluttersdk/magic_starter#101) and five uptizm controls were nameless too (#87).
Second half of the same defect class as the anchor change, found by the consumer audit that produced it. `WCheckbox`'s anchor callback was gated on `disabled` alone, so a caller passing `onChanged: null` (a read-only summary row, or a tile whose own tap drives the toggle) still installed `() => onChanged?.call(!value)`: a control that announces itself as pressable and runs a no-op when pressed. Found in a consumer's region picker, where `IgnorePointer(child: WCheckbox(value: selected, onChanged: null))` published a 16x16 nameless node carrying a tap action inside a tile that was already doing the work, because `IgnorePointer` blocks pointers and leaves the semantics node in place. The gate is now `disabled || onChanged == null`. The `checked` state is still reported either way, so a read-only checkbox still says whether it is ticked. Also lands the measurement that settled the anchor change's shape. Keeping `MergeSemantics` on the gestureless path looked tidier and was wrong: it made a styling-only wrapper ABSORB a descendant control's role and actions, so the same locked region tile published itself as "US West, button" with the checkbox's tap. That is the identical bogus claim one level up, so the wrapper publishes nothing at all. Two new tests, one per direction: a null onChanged offers no tap in the checkbox's subtree, a non-null one still does. The first fails without the gate. Suite 1703 green at 94.8%.

Review caught that the new text overstated the change. `semanticLabel` is checked BEFORE the gesture guard, so a labelled anchor publishes its button node whether or not it carries a gesture, and four places said a gestureless anchor publishes nothing full stop. Measured, to be sure which way to fix it: `WAnchor(semanticLabel: 'Decorative', child: Icon(...))` with no gesture publishes `btn=true tap=false label="Decorative"`. Documented rather than guarded, because the exception is load-bearing. An existing test pins `isDisabled: true, onTap: null, semanticLabel: 'Save'` as a button, and it is right: a disabled control has to tell assistive technology that a control is there and currently unavailable. Extending the guard would have taken that away. So the rule is that the ROLE follows the gesture, the LABEL is a statement of intent, and `WDiv`'s auto-wrap never passes one. A new test pins the exception from the enabled side, which nothing covered: named, one node, no tap action.

Resolves the CHANGELOG conflict: master's `### Fixed` bullet and this branch's two sit at the same position, and master also carries the whole `### Quality` section. All three Fixed bullets now sit under Fixed, master's first because it landed first, with Quality kept last. No wording changed on either side. This is the first build combining #180's whitespace token scan with the semantics changes here, so the full gate ran rather than the workflow-only subset: 1706 tests passed, 1 skipped, coverage 94.8%.
…aim (#86) The "Open, not yet fixed" section outlived all three of its entries. F6 closed in #85 (wall-clock rotation boundaries) and the unlabelled shell controls in #83 (ShellControlSemantics). The third entry was half right and its load-bearing half was wrong. Real: WDiv auto-wraps into a gestureless WAnchor for hover state and WAnchor published a button role regardless, so a decorative hoverable card was offered as a control whose entire action set was `focus`, with no tap behind it. Fixed upstream in fluttersdk/wind#182. Not real: the double announcement. That shape put two button nodes in the WIDGET tree, which is what the original reading counted, but the inner one carried `isMergedIntoParent`, so Flutter folded it into the real tap surface and never sent it to the platform. F19 had already reached that conclusion from the DOM side and said so. The open list kept the claim anyway, which is the point of recording this: a retraction in one place and not the other is how a corrected finding gets re-fixed. The nameless-control half was real and larger than first thought: MSPageHeader's back control was unnamed on every detail page (fluttersdk/magic_starter#101) and five uptizm controls were nameless too (#87).
…ing (#87) Two findings, one method. Walking all 28 component previews and asserting that no platform button node is nameless found controls no widget test could see: a widget test asserts on the widget it built, and `tester.getSemantics` resolves one widget's node, so neither can notice a control that renders correctly and announces nothing. Named, all icon-only and all previously silent to a screen reader: - the key-value editor's row remove (`uptizm.a11y.remove_row`) - the string-value chip remove, which names the value it drops (`uptizm.a11y.remove_value`), because several chips sit in one row and "remove" alone does not say which one - the status-page brand swatch, which names its hex (`uptizm.a11y.select_brand_color`): eight colour circles were eight identical unnamed buttons, and the hex is all that distinguishes them - the status-page preview image, which opens the full render (`uptizm.a11y.open_full_preview`) The region picker's tick is different: it is decoration, since the tile tap drives the toggle, and `IgnorePointer` blocks pointers while leaving the semantics node in place. It now also carries `ExcludeSemantics`, so the tile announces its region once instead of hiding a second nameless control inside itself. The notification bell's header was a `Row` holding an `Expanded` title and an unconstrained action, and the panel is `w-80`, so a 294px content row. Measured against the shipped catalogues at their real styles: the title needs 157 in Turkish and 186 in English, the action 196 in English and 355 in Turkish. English silently clipped its title to 98px; Turkish threw `A RenderFlex overflowed by 61 pixels`. A `Wrap` drops the action to its own line rather than clipping either label, and the Turkish label is now "Tümünü oku", which fits beside the title on one line. The suite could not see any of it: this file's loader hands out English LITERALS, so every assertion passed by construction. The two new header tests read the shipped catalogue for both locales and assert that each label renders at the width it needs, not merely that nothing threw. Both fail with the `Row` restored. The new audit covers the 24 component previews. The three screen previews are excluded because they mount live views whose controllers schedule timers a widget test cannot drain, so they fail on "A Timer is still pending" whatever their semantics; the live dusk walk covers whole screens. Two more findings from the same pass live upstream, and are PRs there: fluttersdk/wind#182 (a gestureless `WAnchor` published a button role with no tap action, and `WCheckbox` installed a tap for `onChanged: null`) and fluttersdk/magic_starter#101 (`MSPageHeader`'s back control was unnamed on every page).

What
Two commits, one defect class: a widget publishing an affordance with nothing behind it.
WAnchorwith no gesture no longer publishesSemantics(button: true). An anchor carryingonTap,onLongPressoronDoubleTapis unchanged, and an explicitsemanticLabelstill wins.WCheckboxno longer installs a tap foronChanged: null. The gate wasdisabledalone; it is nowdisabled || onChanged == null. Thecheckedstate is still reported, so a read-only checkbox still says whether it is ticked.Docs corrected where they stated the old unconditional behaviour:
doc/widgets/w-anchor.md(new Accessibility section),doc/widgets/w-div.md,skills/wind-ui/SKILL.md(v2.12.1),skills/wind-ui/references/widgets.md.Why
WDivauto-wraps itself in aWAnchorwhenever its className carrieshover:,focus:oractive:, purely to get the state that widget tracks. Publishing a button node for that wrap made a claim the widget cannot keep.Measured on
WDiv(className: 'px-4 py-3 hover:bg-slate-100', child: WText('Latency')):focusis the entire action set: notap. A screen reader offers a decorative card as a control, the user activates it, and nothing happens. After the change the card keeps its name and loses the role.The checkbox is the same shape one level down. In a consumer's region picker,
IgnorePointer(child: WCheckbox(value: selected, onChanged: null))published a 16x16 nameless node with a tap action, inside a tile that was already driving the toggle:IgnorePointerblocks pointers and leaves the semantics node in place.A claim I retired instead of shipping
The first version of this PR also said that
WAnchor(onTap:) > WDiv(hover:...), the shape every card and list row is written in, announced twice. That is wrong, and it was in the commit message, the CHANGELOG, the source comment and this description before I measured it.The shape does put two button nodes in the widget tree. But the inner one carries
isMergedIntoParent:Flutter sends only the parent, so no screen reader ever read that row twice. The reading that produced the claim counted raw tree nodes. The test helper now filters merged nodes, and the test covering that shape is labelled a regression guard rather than a reproducer, because it passes with and without the fix.
Why
MergeSemanticsgoes rather than staysKeeping the merge and dropping only the role looked tidier, and measuring it killed the idea: a styling-only wrapper then absorbed a descendant control's role and actions. The same locked region tile, whose own anchor has no gesture, swallowed the display-only
WCheckboxand published itself as "US West, button" carrying the checkbox's tap. That is the identical bogus claim one level up, so the gestureless path publishes nothing at all.Testing
