* fix(core): handle invisible Unicode characters in disable comments (#1472)
When TERMINAL_EMULATOR=JetBrains-JediTerm is set (or similar IDE/terminal
configurations), invisible Unicode characters like zero-width spaces
(U+200B, U+200C, U+200D) and zero-width no-break spaces (U+FEFF/BOM) can
appear at the end of lines. These characters are not matched by JavaScript's
\s regex class, causing the $ anchor in react-doctor-disable patterns to
fail despite the characters being invisible in editors and terminal output.
This fix adds explicit matching for common invisible Unicode characters
before the $ anchor in both DISABLE_NEXT_LINE_PATTERN and DISABLE_LINE_PATTERN,
making them resilient to these characters while maintaining the $ precision
that near-miss detection relies on.
The foreign disable patterns (eslint-disable, oxlint-disable) never anchored
to $ and were unaffected, which is why oxlint-disable-next-line worked while
react-doctor-disable-next-line failed in the reproduction case.
Fixes#1472

* fix(oxlint-plugin): prevent stack overflow in walkAst on deeply nested code
Issue #1438: react-doctor 0.9.0 crashes with 'RangeError: Maximum call stack
size exceeded' when analyzing deeply nested async functions with multiple
try/catch blocks.
Root cause: walkAst() used recursive tree traversal via nested function calls,
hitting V8's stack limit (~10k-15k frames) on pathological but real code —
large orchestrator functions with nested async helpers, each wrapped in
try/catch, plus deep if/else branching.
Fix: Convert walkAst() to iterative traversal using an explicit stack. This
eliminates unbounded recursion while preserving identical visitor semantics
(early-exit via 'return false', depth-first left-to-right order).
Also add memoization to subtreeCanThrowSynchronously's isInsideAbsorbingTry
to cache (node, boundary) results and avoid redundant ancestor walks + catch
handler analysis.
The iterative walkAst benefits all 745 rules that traverse ASTs, not just the
throw-analysis rules that triggered this report.

* 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.
