* feat(rules): add 10 motion, accessibility, and design lint rules
Derived from a cross-resource design reference (every principle from the
design knowledge base), deduped against the full existing rule inventory.
Motion: extend no-transition-all to the Tailwind `transition-all` class
(was inline-only) and add no-tailwind-layout-transition for arbitrary
`transition-[<layout-prop>]`.
Accessibility: no-autoplay-without-muted, no-uninformative-aria-label,
no-target-blank-without-rel, and no-low-contrast-inline-style (computes the
real WCAG 2.1 ratio from co-located inline color + backgroundColor).
Design/Tailwind hygiene: no-redundant-display-class, prefer-truncate-shorthand,
no-full-viewport-width, and no-svg-currentcolor-with-fill-class.
All register via codegen (388 rules); 77 co-located tests pass; typecheck,
lint, and format clean.
* fix(rules): correct two false positives found in rule-validate
- no-low-contrast-inline-style: when the inline style has no `fontSize`,
the text may be sized large via a class (`text-5xl`), so fall back to the
lenient 3:1 large-text threshold instead of 4.5:1 to avoid flagging large
text that only needs 3:1. Stricter 4.5:1 applies only when the size is a
visible normal size.
- no-redundant-display-class: `<li>` defaults to `display: list-item`, not
`block`, so `block` on an `<li>` is meaningful — removed `li` from the
block-default set.
Adds regression tests for both.
* fix(rules): resolve Cursor Bugbot findings
- no-low-contrast-inline-style: use a solid `background` shorthand color as
the background (was skipped entirely, missing low-contrast pairs); skip only
gradients/images/ambiguous (both backgroundColor + background). Also treat a
string `fontWeight: "700"` as bold for the large-text threshold.
- no-transition-all: match `transition-all` as a whole Tailwind token (segment
after variant prefixes) so compound classes like `transition-all-custom` are
not falsely flagged.
- no-svg-currentcolor-with-fill-class: exclude stroke-WIDTH utilities
(`stroke-2`, `stroke-[1.5]`) — they set thickness, not color — so they no
longer false-conflict with `stroke="currentColor"`.
Adds regression tests for each.
* feat(rules): add 3 Tailwind-canonicalization rules from ui.sh guidance
- no-deprecated-tailwind-class: flag Tailwind v4 renames (bg-gradient-* →
bg-linear-*, flex-shrink-* → shrink-*, flex-grow-* → grow-*,
overflow-ellipsis → text-ellipsis). Gated on a new `tailwind:4` capability.
- no-arbitrary-px-font-size: `text-[13px]` → rem so text scales with the
user's root font size (px stays fine for border-*/outline-*).
- prefer-dvh-over-vh: `h-screen`/`min-h-screen`/`h-[100vh]` → dvh (tailwind:3.4).
Adds `tailwind:4` capability to @react-doctor/core and extracts a shared
`get-class-name-tokens` util (variant-aware token splitting), reused by
no-transition-all and no-svg-currentcolor-with-fill-class.
* fix(rules): adversarial-review false positives in the new design rules
- no-tailwind-layout-transition: match transition-[…] property names exactly
(comma-split + set) so SVG `stroke-width` / `border-width` — which merely
contain "width" — are no longer flagged as HTML layout thrash.
- no-full-viewport-width: drop `max-w-*` / `maxWidth` (a defensive cap, not the
overflow footgun); keep `w-screen`/`w-[100vw]`/`width`/`minWidth`.
- prefer-dvh-over-vh: drop `max-h-*` / `maxHeight` (a valid height cap, e.g. a
scrollable modal); keep `h-screen`/`min-h-screen`/`height`/`minHeight`.
- no-deprecated-tailwind-class: only rename `bg-gradient-to-*` → `bg-linear-to-*`
(v4 radial/conic are `bg-radial`/`bg-conic`, not `bg-linear-radial`).
Adds regression tests for each false positive.
* fix(rules): resolve thermo-review false positives
- no-svg-currentcolor-with-fill-class: only treat UNPREFIXED `fill-*`/`stroke-*`
color classes as conflicts; `hover:fill-blue-600` / `dark:fill-white` (state-
gated, no static conflict with the base `fill="currentColor"`) are no longer
flagged — a very common icon pattern.
- no-low-contrast-inline-style: reject 4-arg `rgb(0,0,0,0.5)` / slash-form alpha
(was judged opaque), and bail when the style object contains a `{...spread}`
that could override the colors. Tag `test-noise` to match sibling no-tiny-text.
- no-full-viewport-width: drop the redundant `category: "Architecture"` override
(it's the design-bucket default).
- Extract `has-jsx-spread-attribute` util; use it in the two a11y rules.
Adds regression tests for the variant-prefixed svg classes, rgb-alpha, opaque
rgb, and the style-spread bail.
* refactor(rules): deslop the design/motion/a11y rule additions
Consolidate duplication surfaced by an adversarial deslop pass; no behavior
change (the same diagnostics fire for the same inputs):
- no-autoplay-without-muted: fold isStaticallyTrue/isStaticallyFalse into one
tri-state resolveStaticBoolean, mirroring the existing parseJsxValue idiom
- no-svg-currentcolor-with-fill-class: collapse the duplicated fill/stroke
branches into a single loop over the two paint attributes
- no-low-contrast-inline-style: hoist the repeated `properties` fallback
- no-uncontrolled-input: drop the local hasJsxSpreadAttribute copy in favor of
the branch's new shared utils/has-jsx-spread-attribute, completing the extraction

* fix(rules): no-deprecated-tailwind-class stops flagging overflow-clip
`overflow-clip` is a current Tailwind utility for `overflow: clip` (v3.1+,
still present in v4) — it was never renamed to `text-clip`, which sets the
unrelated `text-overflow: clip`. The stray mapping produced an incorrect
"renamed in v4" suggestion (Cursor Bugbot). Only `overflow-ellipsis ->
text-ellipsis` is a real rename; keep that. Adds a regression test.

* fix(capabilities): require a confirmed Tailwind major for the tailwind:4 gate
`tailwind:4` gates no-deprecated-tailwind-class, which tells users a class was
renamed/removed in v4. The optimistic-on-null policy (assume latest for an
unparseable spec like `workspace:*`) is right for the suggestion rule behind
`tailwind:3.4`, but for a deprecation rule it surfaces confidently-wrong
"renamed in v4" warnings on a v3 project. Require a CONFIRMED parsed major >= 4
for tailwind:4 — favor a false negative over a false positive (Cursor Bugbot).
`tailwind:3.4` stays optimistic. Adds an unparseable-version regression test.

* fix(rules): resolve Bugbot/Devin review findings on design/a11y rules
- no-full-viewport-width: match variant-prefixed `md:w-screen` / `lg:min-w-screen`, mirroring the sibling `prefer-dvh-over-vh` regex (overflow happens at every breakpoint).
- no-target-blank-without-rel: resolve `rel={'noopener'}` expression-container literals instead of treating them as dynamic, so reverse-tabnabbing isn't silently missed; share one literal resolver with the `target` check.
- Extract the bare `16` root-font-size divisor into `ROOT_FONT_SIZE_PX` per the magic-number convention.
* fix(rules): no-uninformative-aria-label resolves braced string literals
Extracts no-target-blank-without-rel's inline getStringLiteralAttributeValue
into a shared util and uses it in no-uninformative-aria-label, so a static
braced literal like aria-label={'icon'} is judged instead of silently skipped
(getJsxPropStringValue only handles plain string literals). Adds regression
tests for the braced uninformative and braced descriptive cases.

* fix(effect-needs-cleanup): address review findings on fix/effect-cleanup-loop-pairs
- effect-needs-cleanup.ts:1692 — require an exhaustive removal loop in doesReleaseCallMatchUsage's for-of pairing so retained-handler analysis (fileContainsReleaseForUsage) no longer treats a break-truncated loop as a full release; pinned both directions plus the effect-cleanup path in effect-needs-cleanup.regressions.test.ts
- utils/resolve-event-listener-capture.ts — folded the rule-local resolveStaticEventListenerCapture fork into the shared resolveEventListenerCapture behind allowComputedString/allowIndeterminateEntries options; both consuming rules keep their exact prior semantics
- packages/fuzz/corpus — relocated the true-positive fixture effect-needs-cleanup--assignment-form-loop-mismatch.tsx out of the confirmed-false-positive regressions/ directory into new true-positives/, and documented (README, smoke test, fuzz skill) that firing expectations live in the rule's unit suite, not the fuzz harness

* fix(rule): ignore async effect callback chains
* fix(rule): exclude async downstream chain links
* test(rule): make async downstream chain-link pins non-vacuous
- no-effect-chain.regressions.test.ts:379-407 — the four "async downstream
chain link" variants used fetch, which main's external-sync suppression
already silenced, so they passed against the pre-fix rule and pinned
nothing; replaced fetch with an opaque loadTargetValue loader mirroring
the corpus fixture, verified all four now fail against origin/main's
rule and pass at head

* feat(oxlint-plugin): no-stale-timer-ref — flag cleared timer refs left holding stale ids
clearTimeout(ref.current) without ref.current = null leaves the old id
truthy, so components that gate behavior on the ref as a "timer pending"
signal re-arm dismissed work or skip future scheduling. Skips the
clear-then-null and clear-then-re-arm (debounce) shapes, bare clear-guard
idioms, and effect-cleanup returns.
* fix(oxlint-plugin): no-stale-timer-ref — resolve the cleared ref via closest binding
A shadowing parameter or local re-declaration of the ref name was
misattributed to the outer useRef binding, flagging clears on non-ref
receivers. Resolve through findVariableInitializer (closest-scope, the
advanced-event-handler-refs pattern) instead of a bespoke scope walker,
consolidate the duplicated clear-call parsing, extract the getRangeStart
helper shared with effect-needs-cleanup, and drop the body casts in
favor of the isFunctionLike guard.
* fix(oxlint-plugin): no-stale-timer-ref — exempt component-level cleanups returned from an effect
Bugbot: a cleanup arrow declared in the component body and handed to
useEffect via `return stop` was never linked to the effect by the
nesting walk, so its clear was flagged despite being an effect-cleanup
return. Match the clearing function's binding name against every
effect's returned identifier in the owner scope.
* test(fuzz): timer-ref handler snippets + audit no-stale-timer-ref for verdict robustness
The generator had no useRef-held timer shape, so no-stale-timer-ref was
silent under fuzz (only its early bails were exercised). Two handler-pool
snippets (guarded schedule/cancel and debounce queue/flush) make it fire
12-23 programs per 500-iteration run, and the rule joins AUDITED_RULE_IDS
since its liveness fixture survives every must-preserve rewrite.
Fuzz: add the verdict-drop oracle — semantics-preserving source rewrites
(parenthesized/cast/non-null receivers, concise-arrow-to-block returns,
no-op prologues, optional-chain and computed-member spellings) applied to
firing programs; a rule that goes silent under one keys on incidental
token shape. Wired into fuzz-rule as an advisory finding kind, a strict
per-rule robustness suite over the audited liveness fixtures, a
registry-wide census script, and new regression-corpus entries.
Rules: add no-locale-format-in-render (locale/timezone-dependent
formatting during render in SSR-capable projects → hydration mismatch,
gated off client-only frameworks) and extend
prefer-use-sync-external-store to detect hand-rolled module-scope stores
(let + listener set + subscribe fn consumed via useState snapshot +
useEffect subscription).
Robustness sweep: shared is-no-op-statement / is-global-method-call /
executes-during-render utilities and cast-wrapper unwrapping across the
rule registry so detection survives the rewrites above; census is 0
drops across all fixture-covered rules.
