Summary

Adds 18 advanced design analysis capabilities across the full stack:

Deterministic Lint Modules (plugin sandbox)

  • Fitts's Law — target size, consecutive click difficulty (ID >4.0 bits), mobile thumb zone violations
  • Gestalt proximity/continuity — spatial clustering, alignment continuity within 2px tolerance
  • Detached instance detectiondetachedInfo API + heuristic fallback for FRAME nodes with component naming
  • Dark mode validation — pure black backgrounds, pure white text, identical light/dark values, missing mode values
  • Responsive design prediction — fixed-width detection, text truncation risk, missing layoutWrap, breakpoint variant checking
  • Real-time incremental lintingfigma.on('documentchange') with debounced re-lint of affected nodes

Design System Compliance (plugin sandbox)

  • DTCG token parser — W3C .tokens.json format with $type inheritance
  • Token compliance engine — Levenshtein fuzzy matching (threshold 3), adoption scoring
  • Variable system collector — full Figma variable extraction (collections, modes, consumers, adoption rate)
  • Mode comparator — light/dark variable value diffing
  • Design debt score — composite metric (orphaned styles, detached instances, hardcoded values, naming violations)

AI Analysis Pipelines (backend — 11 new routes)

  • Attention + Nielsen's Heuristics — focal point prediction, F/Z reading flow, 6 automatable heuristics
  • Cognitive Walkthrough — multi-image prompt, 4 CW questions per step (max 10 frames)
  • PURE Scoring — 3 parallel evaluators (UX Designer, A11y Specialist, Business Analyst), word-overlap dedup, consensus detection
  • Brand Consistency — color tolerance, typography, spacing, personality evaluation
  • Copy/Tone Consistency — text-only analysis (no screenshots, saves tokens), terminology/tone drift

  • Snyk code scan — 0 security issues

Test plan

  • Select a component in Figma → run lint → verify Fitts's Law, Gestalt, detached instance checks appear
  • Test with dark mode variables → verify dark mode validation catches pure black/white/missing modes
  • Run "Sweep Page" on a multi-frame page → verify PageSweepCard renders with scores
  • Hit each new backend endpoint (/api/cognitive-walkthrough, /api/pure-scoring, etc.) with valid payloads
  • Enable real-time lint → modify a node → verify incremental re-lint triggers
  • Test DTCG compliance with a .tokens.json file

Action required

1. Realtime lint invalid nodes 🐞 Bug ⛯ Reliability
Description
Realtime lint adds STYLE_PROPERTY_CHANGE IDs and then casts any non-PAGE/DOCUMENT node returned by
getNodeByIdAsync to SceneNode before calling runDesignLint, which can lint non-scene entities
or cause runtime errors/meaningless updates.
Code

src/lint/realtime-lint.ts[R31-85]

+function onDocumentChange(event: DocumentChangeEvent): void {
+  if (!realtimeConfig || !realtimeConfig.enabled) return;
+
+  for (const change of event.documentChanges) {
+    // Only react to property changes and creations — not deletes
+    if (change.type === 'PROPERTY_CHANGE' || change.type === 'CREATE' || change.type === 'STYLE_PROPERTY_CHANGE') {
+      if ('id' in change && typeof change.id === 'string') {
+        pendingNodeIds.add(change.id);
+      }
+    }
+  }
+
+  if (pendingNodeIds.size === 0) return;
+
+  // Debounce: clear previous timer and start new one
+  if (debounceTimer !== null) {
+    clearTimeout(debounceTimer);
+  }
+
+  const debounceMs = realtimeConfig.debounceMs || 500;
+  debounceTimer = setTimeout(() => {
+    processChangedNodes();
+  }, debounceMs) as unknown as number;
+}
+
+/**
+ * Fetch each changed node, filter to valid SceneNodes, and re-lint.
+ */
+async function processChangedNodes(): Promise<void> {
+  if (!realtimeConfig) return;
+
+  const nodeIds = Array.from(pendingNodeIds);
+  pendingNodeIds.clear();
+  debounceTimer = null;
+
+  const changedNodes: SceneNode[] = [];
+  const changedNodeIds: string[] = [];
+
+  for (const id of nodeIds) {
+    try {
+      const node = await figma.getNodeByIdAsync(id);
+      if (node && 'type' in node && node.type !== 'PAGE' && node.type !== 'DOCUMENT') {
+        changedNodes.push(node as SceneNode);
+        changedNodeIds.push(id);
+      }
+    } catch {
+      // Node may have been deleted between change event and processing — skip
+    }
+  }
+
+  if (changedNodes.length === 0) return;
+
+  try {
+    const result = runDesignLint(changedNodes, realtimeConfig.settings);
+
Evidence
The realtime handler intentionally tracks style changes (STYLE_PROPERTY_CHANGE) but only filters
out PAGE/DOCUMENT before casting to SceneNode. runDesignLint explicitly requires SceneNode[],
so this is an unsafe assumption at the integration boundary.

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
Realtime lint casts arbitrary nodes to `SceneNode` and lints them. Because it also tracks `STYLE_PROPERTY_CHANGE`, it can end up linting objects that are not part of the scene graph.

### Issue Context
`runDesignLint` operates on `SceneNode[]`. The realtime pipeline must guarantee only those are passed.

2. Responsive percent divides zero 🐞 Bug ✓ Correctness
Description
Responsive text truncation messaging divides by textNode.width without guarding for 0/invalid
widths, producing Infinity%/NaN% in lint output.
Code

src/lint/responsive.ts[R161-185]

+    // Only check text nodes with fixed width (not auto-width or auto-height)
+    if (textResize === 'NONE' || textResize === 'TRUNCATE') {
+      const charCount = textNode.characters.length;
+      const estimatedTextWidth = charCount * (fontSize as number) * AVG_CHAR_WIDTH_RATIO;
+      const nodeWidth = textNode.width;
+
+      // Flag if text fills > 80% of available width
+      if (charCount > 5 && estimatedTextWidth > nodeWidth * 0.8) {
+        riskCount++;
+        failed++;
+        issues.push({
+          id: nextId(),
+          type: 'responsive',
+          severity: 'info',
+          nodeId: node.id,
+          nodeName: node.name,
+          message: `Text "${node.name}" may truncate — content fills ~${Math.round((estimatedTextWidth / nodeWidth) * 100)}% of fixed width (${Math.round(nodeWidth)}px). Translations or dynamic content could overflow.`,
+          currentValue: `${charCount} chars in ${Math.round(nodeWidth)}px`,
+          suggestions: [
+            'Use auto-width or auto-height text resizing',
+            'Allow text to wrap by setting textAutoResize to HEIGHT',
+            'Add ellipsis handling if truncation is intentional',
+          ],
+          autoFixable: false,
+        });
Evidence
The message template computes a ratio using estimatedTextWidth / nodeWidth where nodeWidth is
taken directly from textNode.width and never validated; JavaScript will yield Infinity/NaN
when width is 0/invalid.

src/lint/responsive.ts[161-185]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
The responsive lint module can emit invalid percentages due to division by zero/invalid widths.

### Issue Context
The % is used only for messaging, but broken output reduces trust and can leak into UI displays.

3. Parallel analysis wastes tokens 🐞 Bug ➹ Performance
Description
POST /api/analyze runs runExtendedAnalysis() in Promise.all() alongside runAnalysis(), so if
runAnalysis() fails early (e.g., invalid sessionId) the extended Anthropic call can still be
in-flight, wasting cost/latency despite the request returning an error.
Code

backend/src/routes/analyze.ts[R47-59]

+    // Run core analysis and extended analysis in parallel
+    const [coreResult, extendedResult] = await Promise.all([
+      runAnalysis(body),
+      hasExtended
+        ? runExtendedAnalysis(
+            body.screenshot,
+            body.lintResult,
+            body.extractedData,
+            body.sessionId ?? '',
+            features,
+          )
+        : Promise.resolve(undefined as ExtendedAnalysisResult | undefined),
+    ]);
Evidence
The route unconditionally starts both the core and extended jobs concurrently, while runAnalysis()
can throw immediately on an unknown session, and the extended job performs an Anthropic request
(messages.create). This creates an avoidable cost/latency race when the core path errors out.

backend/src/routes/analyze.ts[40-59]

backend/src/services/extended-analyzer.ts[154-180]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`/api/analyze` starts extended AI work in parallel with core analysis. If core analysis fails early (notably when `sessionId` does not exist), the extended Anthropic call can still be sent, wasting cost and time.

### Issue Context
`runAnalysis()` already enforces that a provided `sessionId` must exist and throws if it does not. Because the route uses `Promise.all`, the extended task is started even when that validation is going to fail.

4. Page sweep lacks frame cap 🐞 Bug ⛨ Security
Description
The backend /api/analyze-page endpoint has no server-side cap on frames, and the service builds
large per-frame summaries over all frames, allowing oversized requests to consume CPU/memory and
inflate prompt construction.
Code

backend/src/routes/page-sweep.ts[R15-20]

+    if (!body.frames || !Array.isArray(body.frames) || body.frames.length === 0) {
+      return c.json({ error: 'Missing frames array' }, 400);
+    }
+
+    const result = await analyzePageSweep(body);
+    return c.json({ success: true, ...result });
Evidence
The route only checks that frames is non-empty, then passes through to analyzePageSweep, which
processes every frame and creates a giant frameSummaries string. The plugin UI currently slices to
50 frames, but the backend endpoint is still directly callable and should enforce its own limits.

backend/src/routes/page-sweep.ts[15-20]
backend/src/services/page-sweep-analyzer.ts[91-108]
backend/src/services/page-sweep-analyzer.ts[180-190]
src/ui/message-handler.ts[1551-1552]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`/api/analyze-page` accepts an unbounded `frames` array and the service builds large summaries across all frames, creating DoS risk.

### Issue Context
Even though the plugin currently caps to 50 frames, the backend endpoint should not rely on UI behavior for safety.

### Fix Focus Areas

- backend/src/services/page-sweep-analyzer.ts[91-108]

SyntaxError or other parse issues, log the raw jsonMatch[0] and the error (using
the same logger used in this file), and return a controlled response (e.g., a

57-90: ⚠️ Potential issue | 🟠 Major

consumers сейчас считает не узлы, а отдельные привязки.

По контракту VariableData.consumers — это количество узлов, использующих переменную. Здесь счётчик увеличивается на каждое найденное binding-вхождение, поэтому один узел с той же переменной в нескольких свойствах завышает число; одновременно реально проверяются только fills, хотя комментарий обещает ещё strokes. Из-за этого consumers и unusedVariables становятся недостоверными.

in the block that examines boundVariables (and the subsequent fills loop) to
collect unique variable ids seen for the node (e.g., use a local Set seenIds),
include strokes in the same scan (n.strokes similar to n.fills), and after
scanning node.boundVariables, n.fills and n.strokes, increment consumerMap once
per unique id for that node (and set nodeBound = true if seenIds non-empty).
Update references around consumerMap, nodeBound, n.boundVariables, n.fills and
n.strokes so consumers counts reflect number of nodes using each variable, not
number of bindings.

requiring both a higher overlap threshold (e.g., >= 0.7) AND at least one shared
high-value token such as the same noun or bigram (use simple POS-filtering or
require shared tokens of length>4 that appear in both as exact matches or shared
bigrams), or replace the simple ratio with a normalized similarity on lemmatized

separate severity entries or merge metadata without raising severity in the
combinedIssue (only update counts), and update the logic in the existing

Нормализация сейчас падает на не-объектах внутри массивов.

Во всех ветках Array.isArray(...)? ...map(...) : [] элементы сразу читаются как объекты.

figma.currentPage.findAll(() => true) уже возвращает всех потомков страницы, а countVariableConsumers() затем ещё раз рекурсивно идёт по children. Вложенные узлы будут посчитаны по нескольку раз, поэтому totalEligible, boundCount и все consumer totals раздуваются почти на любой вложенной иерархии.

1. Realtime lint invalid nodes 🐞 Bug ⛯ Reliability

Realtime lint adds STYLE_PROPERTY_CHANGE IDs and then casts any non-PAGE/DOCUMENT node returned by
getNodeByIdAsync to SceneNode before calling runDesignLint, which can lint non-scene entities
or cause runtime errors/meaningless updates.
Agent Prompt
### Issue description
Realtime lint casts arbitrary nodes to `SceneNode` and lints them. Because it also tracks `STYLE_PROPERTY_CHANGE`, it can end up linting objects that are not part of the scene graph.

### Issue Context
`runDesignLint` operates on `SceneNode[]`. The realtime pipeline must guarantee only those are passed.

Проверка текстовых стилей в rich text неполная — возможны ложные срабатывания.

Текстовые узлы с форматированием по сегментам могут применять стили только на уровне отдельных участков текста, не устанавливая top-level textStyleId. Код проверяет только textStyleId узла (строка 194), но пропускает стили в сегментах, доступные через getStyledTextSegments(). Это приводит к ложным срабатываниям об "осиротевших" текстовых стилях.

Рекомендуется для TextNode дополнительно собирать ID стилей из сегментов текста через getStyledTextSegments(['textStyleId']).

Логика проверки constraint'ов не учитывает направление оси.

При primaryMode === 'FILL' проверяются сразу оба constraint'а (width и height). Однако primaryAxisSizingMode зависит от layoutMode родителя:

В saveAnalysisResult() не сериализуется aiReview перед сохранением в БД.

analyzer.ts передаёт aiReview как объект AiReviewResult, но saveAnalysisResult() (строка 25) сохраняет его напрямую без JSON.stringify(). База данных ожидает ai_review: string | null (backend/src/db/queries.ts:34), поэтому объект будет сохранён как "[object Object]" или аналогичная поломанная представление. Когда позже loadSession() возвращает эту строку и buildFollowupPrompt() пытается её распарсить, JSON.parse() молча падает в catch, и данные AiReviewResult теряются.

Исправление: в saveAnalysisResult() нужно добавить условное сериализацию для aiReview и lintResult:

ai_review: typeof aiReview === 'string' ? aiReview : JSON.stringify(aiReview),
lint_result: typeof lintResult === 'string' ? lintResult : JSON.stringify(lintResult),

currently writes aiReview and lintResult objects directly to the DB causing them
to be stored as "[object Object]" and later fail to parse in
loadSession/buildFollowupPrompt; update saveAnalysisResult to conditionally
serialize these fields before saving (e.g., for aiReview and lintResult use
typeof value === 'string' ? value : JSON.stringify(value)) so the ai_review

Не считайте неоцениваемую эвристику за pass.

Для статичного скриншота pass означает “эвристика соблюдена”, а не “мы не смогли это проверить”. В таком виде H7/H10 и похожие случаи будут искусственно завышать итоговую оценку и искажать topViolations/summary; здесь нужен отдельный статус вроде not_assessable либо исключение таких эвристик из агрегирования.

Comment thread ui/src/components/shared/TeamConfigPanel.tsx
Backend (4 fixes):
- CRITICAL: safe fallback for page-type parsing — empty/garbage text
  returns 'other' instead of random tokens (claude.ts)
- Nielsen heuristics: add 'not_assessable' rating for heuristics that
  can't be evaluated from a static screenshot (H7, H10)
- Extended features (three-layer, confidence) now fire-and-forget —
  no longer block /analyze response
- Verified saveAnalysisResult already stringifies objects via queries.ts

Lint modules (6 fixes):
- component-props: check node.description instead of non-existent
  ComponentPropertyDefinition.description field
- constraints: use layoutSizingHorizontal/Vertical === 'FIXED' instead
  of width/height > 0; fix counter to track actual issue count
- grid-check: add skipLocked/skipHidden checks for root-level nodes
- multi-theme: add 'theme' to LintIssueType, replace 'naming' type
- typography: cache collectTextNodes results by node.id to avoid
  redundant tree traversals on large documents
- variable-scope: field-specific color scope validation (fills vs
  strokes vs textRangeFills) instead of blanket isColorField check

UI (4 fixes):
- App.tsx: race condition guard for concurrent page sweep requests
- DarkModeCard: show N/A badge + neutral bar when totalChecked === 0
- ScaleEditor: handleBlur always resets isAdding state
- TeamConfigPanel: useEffect syncs initialConfig prop changes

37-40: ⚠️ Potential issue | 🟠 Major

Проверка color-scope всё ещё пропускает часть mismatch’ей.

На Line 37-40 fills по-прежнему смешивает FRAME_FILL, SHAPE_FILL и TEXT_FILL в один bucket, а в VariableUsage на Line 119-124 нет контекста node.type, чтобы их различить. Поэтому hasMatchingScope на Line 254 становится true даже для TEXT_FILL, привязанного к обычному fill, и ветка с COLOR_FIELD_EXPECTED_SCOPES не выполняется. Плюс textRangeFills есть на Line 239, но отсутствует в FIELD_TO_EXPECTED_SCOPES, из-за чего на Line 247-248 функция выходит раньше и этот кейс вообще не валидируется.

In `@src/lint/variable-scope.ts` around lines 37 - 40, FIELD_TO_EXPECTED_SCOPES
currently lumps fills together and omits textRangeFills, and VariableUsage
matching lacks node.type context so hasMatchingScope returns true incorrectly;
update FIELD_TO_EXPECTED_SCOPES to include separate keys for FRAME_FILL,
SHAPE_FILL, TEXT_FILL and textRangeFills (mapping each to their correct expected
scopes), then modify the VariableUsage matching logic (the code that
constructs/uses hasMatchingScope and the branch that checks
COLOR_FIELD_EXPECTED_SCOPES) to consider the node.type or node.kind when
selecting which fill-key to check so TEXT_FILL bindings are only matched against
TEXT-specific expected scopes; ensure the early-return path that checks
FIELD_TO_EXPECTED_SCOPES covers textRangeFills too so the
COLOR_FIELD_EXPECTED_SCOPES branch executes for text-range fills as intended.

279-283: Проверка на устаревший запрос в else-ветке неэффективна.

На строке 280 проверка pageSweepRequestId.current !== requestId всегда будет false, потому что requestId был только что присвоен из ++pageSweepRequestId.current на строке 258. Эта проверка имеет смысл только в асинхронных колбэках (.then/.catch), где между запросом и ответом мог прийти новый запрос.

threeLayerExplanations, confidencedFindings, sessionId) but never persisted or
returned; fix by actually saving extendedUpdates to the session/store after the
log (use the existing session persistence method used elsewhere in analyzer.ts)
and ensure the outer function’s return (the block that currently returns other
results at the end) includes threeLayerExplanations and confidencedFindings so
callers receive those computed values.
- Around line 56-57: The JSDoc for the boolean option threeLayerExplanations is
misleading ("Default: 0 (disabled)"); update the comment to use a boolean
default wording (e.g., "Default: false (disabled)") and, if there's any default
value assignment or config initialization for threeLayerExplanations elsewhere,
ensure it uses false rather than 0 so the type and docs are consistent with the

with .toLowerCase() and switch/whitelist, otherwise default to 'other'); coerce
parsed.confidence to a number and clamp it to the [0,1] range (fallback to 0.5
if missing/NaN); and ensure parsed.signals is an array of strings by filtering
out non-string elements and trimming entries (or map values to String and filter
empty strings) so the returned object (type, confidence, signals) always
conforms to the legacy fallback contract.

- Around line 204-216: The current traversal can push the same frame twice (via

nodes variable), deduplicate by node.id (or id property) and then return that

~239-259 to avoid duplicated issues and summaries.
- Around line 293-323: Сейчас блок, который вычисляет mostCommonCount

columnCounts и вызов issues.push). Исправьте это: при обходе countFreq
определяйте все значения с freq === maxFreq (например собрать их в массив), и
если их больше одного — не помечать кадры как использующие «большинство» (т.е.
пропустить генерацию предупреждений в цикле по columnCounts или заменить текст
сообщения на нейтральный), иначе продолжать как сейчас; обновите логику вокруг
mostCommonCount/uniqueCounts и места, где используется nextId/issues.push, чтобы

- Around line 16-19: The global issueCounter/nextId causes ID collisions across

locally per invocation of checkMultiTheme (e.g., a local counter variable inside
checkMultiTheme) or use a collision-safe generator such as
crypto.randomUUID()/nanoid. Replace references to the module-level nextId with a
new local generator (or call to crypto.randomUUID()) and ensure issues are
assigned IDs from that local generator so each checkMultiTheme run produces
unique, non-overlapping IDs.
- Around line 272-284: The current check only reports when some mode-values are
missing but not when all are missing or when values exist only as stale keys;
update the condition around the issues.push block (where missingModes,
collection.modes, variable, nextId and issues.push are used) to also trigger
when missingModes.length === collection.modes.length or when all present keys
are stale, and adjust the message/currentValue/suggestions to reflect a fully
missing case (e.g., "no values defined for any modes" and "Defined in 0/N modes"
or include stale-state note). Apply the same change to the analogous block
handling modes at the other location (the block around lines 298-318).

and before pushing TextNode, and include the flags in the cache key (or maintain
separate cache maps) so cached results respect the filters; update callers
(checkInconsistentAlignment, checkParagraphSpacing, any other callers) to pass
the correct flags or predicate so aggregate checks only consider
visible/unlocked text.
- Around line 128-156: The code picks the first encountered align as majority

that checks COLOR_FIELD_EXPECTED_SCOPES) to consider the node.type or node.kind
when selecting which fill-key to check so TEXT_FILL bindings are only matched
against TEXT-specific expected scopes; ensure the early-return path that checks
FIELD_TO_EXPECTED_SCOPES covers textRangeFills too so the
COLOR_FIELD_EXPECTED_SCOPES branch executes for text-range fills as intended.

Nitpick comments:
In `@backend/src/services/analyzer.ts`:
- Around line 258-263: Extract the repeated regex + JSON.parse logic into a
shared helper (e.g., parseLLMJsonResponse or parseJsonFromContent) that accepts
the LLM response content (the same object checked in the analyzer code) and
returns either the parsed object or null, performs the /\{[\s\S]*\}/ match,
wraps JSON.parse in try/catch, and validates the expected shape (e.g., ensures
parsed.explanations is an array); then replace the inline code in analyzer.ts
that sets threeLayerExplanations (the block using response.content[0].text.match
and JSON.parse) and the similar block at the other location (around the second
occurrence) to call this helper, handle nulls consistently, and centralize
logging/errors in the helper.

In `@src/lint/multi-theme.ts`:
- Around line 423-433: The loop is awaiting getVariableInfo sequentially for
each collection.variableIds which hurts performance; instead, batch-load all
variables with Promise.all on collection.variableIds mapped to getVariableInfo,
then filter out null/undefined results, push those into collectionVars and
increment totalVariables accordingly, and finally run checkIdenticalAcrossModes,
checkMissingModeValues, and checkModeCountMismatch for each loaded variable (use
the same function names: getVariableInfo, collectionVars, totalVariables,
checkIdenticalAcrossModes, checkMissingModeValues, checkModeCountMismatch).
- Around line 446-449: The current aggregates (identicalAcrossModes,
missingModeValues, contrastDegradation, modeCountMismatch) compute counts by
string-matching issue.message which is brittle; update the issue creation site
(where issues.push is called) to include an explicit discriminant (e.g.,
issue.subtype or issue.code) for each kind of lint error, then change the
aggregations in multi-theme.ts to count by that discriminant (e.g.,
issues.filter(i => i.subtype === 'IDENTICAL_ACROSS_MODES').length) instead of
message.includes; ensure all existing pushes that create these issue objects are
updated to set the new field and adjust any consumers accordingly.

In `@ui/src/App.tsx`:
- Around line 279-283: The check for a stale request inside the synchronous else
branch is redundant because requestId was just set from
++pageSweepRequestId.current; remove the conditional "if
(pageSweepRequestId.current !== requestId) break;" from that else branch and
simply compute deterministicResult via buildDeterministicSweepResult(sweepData)
and call chat.addMessage({ kind: 'page-sweep-result', data: deterministicResult
}); — keep the stale-request check only in asynchronous callbacks (e.g.,
.then/.catch) where requestId can become outdated.

In `@ui/src/components/messages/DarkModeCard.tsx`:
- Around line 146-151: In DarkModeCard.tsx update the toggle button element that
uses expanded and setExpanded to include explicit type="button" and an
aria-expanded={expanded} attribute; locate the button using the expanded state
and setExpanded handler (and the issues array usage for the label) and add these
attributes to prevent accidental form submits and improve accessibility.
- Around line 3-33: The file defines local duplicate types (DarkModeIssue,
DarkModeMetrics, DarkModeSummary, DarkModeData, DarkModeCardProps) that already
exist in ui/src/lib/messages.ts; replace these local definitions by importing
the shared types from that module (e.g., import { DarkModeMetrics,
DarkModeIssue, DarkModeSummary, DarkModeData } from 'ui/src/lib/messages') and
update DarkModeCardProps to reference the imported DarkModeData (or export a
Props type that uses the shared types) so the component in DarkModeCard.tsx uses
the centralized contracts and avoids schema drift.

In `@ui/src/components/shared/TeamConfigPanel.tsx`:
- Around line 84-88: The button toggling the panel in TeamConfigPanel.tsx (the
button using onClick={() => setOpen(o => !o)} and aria-expanded={open}) should
be linked to the collapsible content with aria-controls and an id on the content
element; generate or use a stable unique id (e.g., via React's useId or a
panelId constant) and set the button's aria-controls to that id and the content
container's id to the same value (ensure the content container is the element
that shows/hides and/or has role="region"). Update references to the button,
open state, and the content container (panel element) accordingly so the ARIA
relationship is present and unique per panel.
- Line 10: В файле TeamConfigPanel.tsx удалите локальное дублирование константы
DEFAULT_SPACING_SCALE и импортируйте её из единого источника (тот модуль, где
она уже объявлена, например lint/types), заменив локальное const
DEFAULT_SPACING_SCALE = [...] на: import { DEFAULT_SPACING_SCALE } from
'that-module'; убедитесь, что все использования в компоненте продолжают
ссылаться на DEFAULT_SPACING_SCALE и выполните сборку/тесты чтобы проверить
отсутствие регрессий.

skipHidden/skipLocked сейчас не действуют на агрегатные text-check’и.

collectTextNodes() кеширует всё поддерево без фильтрации, поэтому checkInconsistentAlignment() и checkParagraphSpacing() учитывают скрытые и locked TEXT, хотя traverse() выше их пропускает. Это даёт ложные issues на видимых frame’ах, если внутри есть скрытый caption или locked layer.

In `@src/lint/typography.ts` around lines 79 - 97, collectTextNodes currently
caches and returns all TEXT nodes under a node without respecting
skipHidden/skipLocked, causing checkInconsistentAlignment and
checkParagraphSpacing to report hidden/locked text; change collectTextNodes to
accept the same skip flags (e.g., skipHidden: boolean, skipLocked: boolean) or a
predicate, apply those checks when recursing and before pushing TextNode, and
include the flags in the cache key (or maintain separate cache maps) so cached
results respect the filters; update callers (checkInconsistentAlignment,
checkParagraphSpacing, any other callers) to pass the correct flags or predicate
so aggregate checks only consider visible/unlocked text.

⚠️ Potential issue | 🟡 Minor

При равенстве alignments здесь нет majority.

Если внутри frame один body text LEFT, а другой CENTER, на Line 129-148 код всё равно выберет первый встретившийся align и зафлагит второй как отклонение от majority. Это ложное срабатывание — нужен строгий победитель.

🐛 Возможный фикс
   let maxCount = 0;
   let majorityAlign = 'LEFT';
+  let hasTie = false;
   for (const [align, nodes] of alignments) {
     if (nodes.length > maxCount) {
       maxCount = nodes.length;
       majorityAlign = align;
+      hasTie = false;
+    } else if (nodes.length === maxCount) {
+      hasTie = true;
     }
   }
+
+  if (hasTie) return 0;

In `@src/lint/typography.ts` around lines 128 - 156, The code picks the first
encountered align as majority even on ties; change the logic around
alignments/majorityAlign so a strict majority is required: compute maxCount,
then check how many groups have nodes.length === maxCount and if that count > 1
(tie) do not set a majority (or return 0) and skip flagging; otherwise keep the
current majorityAlign and proceed to call pushIssue for non-majority items.
Update the block that calculates majorityAlign (using alignments and maxCount)
and the subsequent loop that uses majorityAlign so ties produce no issues.

Используйте стабильный идентификатор вместо индекса массива в качестве key.

key={i} приводит к некорректному переиспользованию DOM-узлов при изменении порядка или фильтрации списка. Добавьте id: string; в интерфейс DarkModeIssue и используйте key={issue.id}:

Предлагаемый фикс
 interface DarkModeIssue {
+  id: string;
   type: string;
   severity: string;
   nodeName: string;
   message: string;
   currentValue?: string;
   suggestions?: string[];
 }

is using array index as React keys in displayIssues.map which can cause
incorrect DOM reuse; update the DarkModeIssue interface to include a unique id:
string, ensure all producers of DarkModeIssue supply that id, and change the map

- Wire 8 extended lint modules (layout-sizing, constraints, typography,
  component-props, style-audit, variable-scope, multi-theme, grid-check)
  into message-handler with run-extended-lint command
- Add PluginEvent types for dark-mode-card-result, extended-lint-result,
  extended-lint-error
- Wire App.tsx handlers for all new plugin events (design-debt, dark-mode,
  token-compliance, variable-system, extended-lint, team-config)
- Add QuickActions buttons for Design Debt, Dark Mode, Token Audit in
  expandable "More..." section
- Fix handleCompareModes to auto-detect first multi-mode collection when
  no collectionId provided
- Fix handleCheckDTCGCompliance to work without dtcgJson (self-compliance)
- Separate raw mode-comparison-result (text summary) from
  dark-mode-card-result (DarkModeCard-compatible transform)
- Add backend API functions for extended analysis features
- All 3 projects typecheck clean, build successfully, Snyk SAST clean
