refactor: reconcile workspaceAuthStore with authStore

- Delegate workspace token reads from authStore to workspaceAuthStore
- getAuthHeader(): use workspaceAuthStore.getWorkspaceAuthHeader() instead of sessionStorage
- getAuthToken(): use workspaceAuthStore.getWorkspaceToken() instead of sessionStorage
- onAuthStateChanged logout: use workspaceAuthStore.clearWorkspaceContext()
- Add getWorkspaceToken() to workspaceAuthStore
- Remove WORKSPACE_STORAGE_KEYS import from authStore
- Add authTokenPriority.test.ts with 7 priority chain scenarios

+description: Checks code changes against Architecture Decision Records, with emphasis on ECS (ADR 0008) and command-pattern (ADR 0003) compliance
+severity-default: medium
+tools: [Read, Grep, glob]
+---
+
+Check that code changes are consistent with the project's Architecture Decision Records in `docs/adr/`.
+
+## Priority 1: ECS and Command-Pattern Compliance (ADR 0008 + ADR 0003)
+
+These are the primary architectural guardrails. Every entity/litegraph change must be checked against them.
+
+### Command Pattern (ADR 0003)
+
+All entity state mutations MUST be expressible as **serializable, idempotent, deterministic commands**. This is required for CRDT sync, undo/redo, cross-environment portability, and gateway backends.
+
+Flag:
+
+- **Direct spatial mutation** — `node.pos = ...`, `node.size = ...`, `group.pos = ...` outside of a store or command. All spatial data flows through `layoutStore` commands.
+- **Imperative fire-and-forget mutation** — Any new API that mutates entity state as a side effect rather than producing a serializable command object. Systems should produce command batches, not execute mutations directly.
+- **Void-returning mutation APIs** — New entity mutation functions that return `void` instead of a result type (`{ status: 'applied' | 'rejected' | 'no-op' }`). Commands need error/rejection semantics.
+- **Auto-incrementing IDs in new entity code** — New entity creation using auto-increment counters without acknowledging the CRDT collision problem. Concurrent environments need globally unique, stable identifiers.
+
+### ECS Architecture (ADR 0008)
+
+The graph domain model is migrating to ECS. New code must not make the migration harder.
+
+Flag:
+
+- **God-object growth** — New methods/properties added to `LGraphNode` (~4k lines), `LGraphCanvas` (~9k lines), `LGraph` (~3k lines), or `Subgraph`. Extract to systems, stores, or composables instead.
+- **Mixed data and behavior** — New component-like data structures that contain methods or back-references to parent entities. ECS components are plain data objects.
+- **New circular entity dependencies** — New circular imports between `LGraph` ↔ `Subgraph`, `LGraphNode` ↔ `LGraphCanvas`, or similar entity classes.
+- **Direct `graph._version++`** — Mutating the private version counter directly instead of through a public API. Extensions already depend on this side-channel; it must become a proper API.
+
+### Centralized Registries and ECS-Style Access
+
+All entity data access should move toward centralized query patterns, not instance property access.
+
+Flag:
+
+- **New instance method/property patterns** — Adding `node.someProperty` or `node.someMethod()` for data that should be a component in the World, queried via `world.getComponent(entityId, ComponentType)`.
+- **OOP inheritance for entity modeling** — Extending entity classes with new subclasses instead of composing behavior through components and systems.
+- **Scattered state** — New entity state stored in multiple locations (class properties, stores, local variables) instead of being consolidated in the World or in a single store.
+
+### Extension Ecosystem Impact
+
+Entity API changes affect 40+ custom node repos. Changes to these patterns require an extension migration path.
+
+Flag when changed without migration guidance:
+
+- `onConnectionsChange`, `onRemoved`, `onAdded`, `onConfigure` callbacks
+- `onConnectInput` / `onConnectOutput` validation hooks
+- `onWidgetChanged` handlers
+- `node.widgets.find(w => w.name === ...)` patterns
+- `node.serialize` overrides
+- `graph._version++` direct mutation
+- `getNodeById` usage patterns
+
+## Priority 2: General ADR Compliance
+
+For all other ADRs, iterate through each file in `docs/adr/` and extract the core lesson. Ensure changed code does not contradict accepted ADRs. Flag contradictions with proposed ADRs as directional guidance.
+
+### How to Apply
+
+1. Read `docs/adr/README.md` to get the full ADR index
+2. For each ADR, read the Decision and Consequences sections
+3. Check the diff against each ADR's constraints
+4. Only flag ACTUAL violations in changed code, not pre-existing patterns
+
+### Skip List
+
+These ADRs can be skipped for most reviews (they cover completed or narrow-scope decisions):
+
+- **ADR 0004** (Rejected — Fork PrimeVue) — only relevant if someone proposes forking PrimeVue again
+
+## How to Check
+
+1. Identify changed files in the entity/litegraph layer: `src/lib/litegraph/`, `src/ecs/`, `src/platform/`, entity-related stores
+2. For Priority 1 patterns, use targeted searches:
+
+   ```
+   # Direct position mutation
+   Grep: pattern="\.pos\s*=" path="src/lib/litegraph"
+   Grep: pattern="\.size\s*=" path="src/lib/litegraph"
+
+   # God object growth (new methods)
+   Grep: pattern="(class LGraphNode|class LGraphCanvas|class LGraph\b)" path="src/lib/litegraph"
+
+   # Version mutation
+   Grep: pattern="_version\+\+" path="src/lib/litegraph"
+
+   # Extension callback changes
+   Grep: pattern="on(ConnectionsChange|Removed|Added|Configure|ConnectInput|ConnectOutput|WidgetChanged)" path="src/lib/litegraph"
+   ```
+
+3. For Priority 2, read `docs/adr/` files and check for contradictions
+
+## Severity Guidelines
+
+| Issue                                                    | Severity |
+| -------------------------------------------------------- | -------- |
+| Imperative mutation API without command-pattern wrapper  | high     |
+| New god-object method on LGraphNode/LGraphCanvas/LGraph  | high     |
+| Breaking extension callback without migration path       | high     |
+| New circular entity dependency                           | high     |
+| Direct spatial mutation bypassing command pattern        | medium   |
+| Mixed data/behavior in component-like structures         | medium   |
+| New OOP inheritance pattern for entities                 | medium   |
+| Contradicts accepted ADR direction                       | medium   |
+| Contradicts proposed ADR direction without justification | low      |
+
+## Rules
+
+- Only flag ACTUAL violations in changed code, not pre-existing patterns
+- If a change explicitly acknowledges an ADR tradeoff in comments or PR description, lower severity
+- Proposed ADRs carry less weight than accepted ones — flag as directional guidance
+- Reference the specific ADR number in every finding

+# ADR Compliance Audit
+
+Audit the current changes (or a specified PR) for compliance with Architecture Decision Records.
+
+## Step 1: Gather the Diff
+
+- If a PR number is provided, run: `gh pr diff $PR_NUMBER`
+- Otherwise, run: `git diff origin/main...HEAD` (or `git diff --cached` for staged changes)
+
+## Step 2: Priority 1 — ECS and Command-Pattern Compliance
+
+Read these documents for context:

+docs/architecture/appendix-critical-analysis.md
+```
+
+### Check A: Command Pattern (ADR 0003)
+
+Every entity state mutation must be a **serializable, idempotent, deterministic command** — replayable, undoable, transmittable over CRDT.

+---
+
+# Adding Deprecation Warnings
+
+Adds backward-compatible deprecation warnings for renamed or removed
+properties using the `defineDeprecatedProperty` helper in
+`src/lib/litegraph/src/utils/feedback.ts`.
+
+## When to Use
+
+- A property or API has been renamed and custom nodes still use the old name
+- A property is being removed but needs a grace period
+- Backward compatibility must be preserved while nudging adoption
+
+## Steps
+
+### 1. Search the Custom Node Ecosystem
+
+Before implementing, assess impact by searching for usage of the
+deprecated property across ComfyUI custom nodes:
+
+```text
+Use the comfy_codesearch tool to search for the old property name.
+Search for both `widget.oldProp` and just `oldProp` to catch all patterns.
+```
+
+Document the usage patterns found (property access, truthiness checks,
+caching to local vars, style mutation, etc.) — these all must continue
+working.
+
+### 2. Apply the Deprecation
+
+Use `defineDeprecatedProperty` from `src/lib/litegraph/src/utils/feedback.ts`:
+
+```typescript
+import { defineDeprecatedProperty } from '@/lib/litegraph/src/utils/feedback'
+
+/** @deprecated Use {@link obj.newProp} instead. */
+defineDeprecatedProperty(
+  obj,
+  'oldProp',
+  'newProp',
+  'obj.oldProp is deprecated. Use obj.newProp instead.'
+)
+```
+
+### 3. Checklist
+
+- [ ] Ecosystem search completed — all usage patterns are compatible
+- [ ] `defineDeprecatedProperty` call added after the new property is assigned
+- [ ] JSDoc `@deprecated` tag added above the call for IDE support
+- [ ] Warning message names both old and new property clearly
+- [ ] `pnpm typecheck` passes
+- [ ] `pnpm lint` passes
+
+### 4. PR Comment
+
+Add a PR comment summarizing the ecosystem search results: which repos
+use the deprecated property, what access patterns were found, and
+confirmation that all patterns are compatible with the ODP getter/setter.
+
+## How `defineDeprecatedProperty` Works
+
+- Creates an `Object.defineProperty` getter/setter on the target object
+- Getter returns `this[currentKey]`, setter assigns `this[currentKey]`
+- Both log via `warnDeprecated`, which deduplicates (once per unique
+  message per session via a `Set`)
+- `enumerable: false` keeps the alias out of `Object.keys()` / `for...in`
+  / `JSON.stringify`
+- `configurable: true` allows further redefinition if needed
+
+## Edge Cases
+
+- **Truthiness checks** (`if (widget.oldProp)`) — works, getter fires
+- **Caching to local var** (`const el = widget.oldProp`) — works, warns
+  once then the cached ref is used directly
+- **Style/property mutation** (`widget.oldProp.style.color = 'red'`) —
+  works, getter returns the real object
+- **Serialization** (`JSON.stringify`) — `enumerable: false` excludes it
+- **Heavy access in loops** — `warnDeprecated` deduplicates, only warns
+  once per session regardless of call count

+description: 'Detect DOM elements where CSS contain:layout+style would improve rendering performance. Runs a Playwright-based audit on a large workflow, scores candidates by subtree size and sizing constraints, measures performance impact, and generates a ranked report.'
+---
+
+# CSS Containment Audit
+
+Automatically finds DOM elements where adding `contain: layout style` would reduce browser recalculation overhead.
+
+## What It Does
+
+1. Loads a large workflow (245 nodes) in a real browser
+2. Walks the DOM tree and scores every element as a containment candidate
+3. For each high-scoring candidate, applies `contain: layout style` via JavaScript
+4. Measures rendering performance (style recalcs, layouts, task duration) before and after
+5. Takes before/after screenshots to detect visual breakage
+6. Generates a ranked report with actionable recommendations
+
+## When to Use
+
+- After adding new Vue components to the node rendering pipeline
+- When investigating rendering performance on large workflows
+- Before and after refactoring node DOM structure
+- As part of periodic performance audits
+
+## How to Run
+
+```bash
+# Start the dev server first
+pnpm dev &
+
+# Run the audit (uses the @audit tag, not included in normal CI runs)
+pnpm exec playwright test browser_tests/tests/containAudit.spec.ts --project=audit
+
+# View the HTML report
+pnpm exec playwright show-report
+```
+
+## How to Read Results
+
+The audit outputs a table to the console:
+
+```text
+CSS Containment Audit Results
+=======================================================
+Rank | Selector                        | Subtree | Score | DRecalcs | DLayouts | Visual
+  1  | [data-testid="node-inner-wrap"] |     18  |  72   |    -34%  |    -12%  |   OK
+  2  | .node-body                      |     12  |  48   |     -8%  |     -3%  |   OK
+  3  | .node-header                    |      4  |  16   |     +1%  |      0%  |   OK
+```
+
+- **Subtree**: Number of descendant elements (higher = more to skip)
+- **Score**: Composite heuristic score (subtree size x sizing constraint bonus)
+- **DRecalcs / DLayouts**: Change in style recalcs / layout counts vs baseline (negative = improvement)
+- **Visual**: OK if no pixel change, DIFF if screenshot differs (may include subpixel noise — verify manually)
+
+## Candidate Scoring
+
+An element is a good containment candidate when:
+
+1. **Large subtree** -- many descendants that the browser can skip recalculating
+2. **Externally constrained size** -- width/height determined by CSS variables, flex, or explicit values (not by content)
+3. **No existing containment** -- `contain` is not already applied
+4. **Not a leaf** -- has at least a few child elements
+
+Elements that should NOT get containment:
+
+- Elements whose children overflow visually beyond bounds (e.g., absolute-positioned overlays with negative inset)
+- Elements whose height is determined by content and affects sibling layout
+- Very small subtrees (overhead of containment context outweighs benefit)
+
+## Limitations
+
+- Cannot fully guarantee `contain` safety -- visual review of screenshots is required
+- Performance measurements have natural variance; run multiple times for confidence
+- Only tests idle and pan scenarios; widget interactions may differ
+- The audit modifies styles at runtime via JS, which doesn't account for Tailwind purging or build-time optimizations
+
+## Example PR
+
+[#9946 — fix: add CSS contain:layout contain:style to node inner wrapper](https://github.com/Comfy-Org/ComfyUI_frontend/pull/9946)
+
+This PR added `contain-layout contain-style` to the node inner wrapper div in `LGraphNode.vue`. The audit tool would have flagged this element as a high-scoring candidate because:
+
+- **Large subtree** (18+ descendants: header, slots, widgets, content, badges)
+- **Externally constrained size** (`w-(--node-width)`, `flex-1` — dimensions set by CSS variables and flex parent)
+- **Natural isolation boundary** between frequently-changing content (widgets) and infrequently-changing overlays (selection outlines, borders)
+
+The actual change was a single line: adding `'contain-layout contain-style'` to the inner wrapper's class list at `src/renderer/extensions/vueNodes/components/LGraphNode.vue:79`.

+## Architecture Decision Records
+
+All architectural decisions are documented in `docs/adr/`. Code changes must be consistent with accepted ADRs. Proposed ADRs indicate design direction and should be treated as guidance. See `.agents/checks/adr-compliance.md` for automated validation rules.
+
+### Entity Architecture Constraints (ADR 0003 + ADR 0008)
+
+1. **Command pattern for all mutations**: Every entity state change must be a serializable, idempotent, deterministic command — replayable, undoable, and transmittable over CRDT. No imperative fire-and-forget mutation APIs. Systems produce command batches, not direct side effects.
+2. **Centralized registries and ECS-style access**: Entity data lives in the World (centralized registry), queried via `world.getComponent(entityId, ComponentType)`. Do not add new instance properties/methods to entity classes. Do not use OOP inheritance for entity modeling.
+3. **No god-object growth**: Do not add methods to `LGraphNode`, `LGraphCanvas`, `LGraph`, or `Subgraph`. Extract to systems, stores, or composables.
+4. **Plain data components**: ECS components are plain data objects — no methods, no back-references to parent entities. Behavior belongs in systems (pure functions).
+5. **Extension ecosystem impact**: Changes to entity callbacks (`onConnectionsChange`, `onRemoved`, `onAdded`, `onConnectInput/Output`, `onConfigure`, `onWidgetChanged`), `node.widgets` access, `node.serialize`, or `graph._version++` affect 40+ custom node repos and require migration guidance.

+## Polling Assertions
+
+Prefer `expect.poll()` over `expect(async () => { ... }).toPass()` when the block contains a single async call with a single assertion. `expect.poll()` is more readable and gives better error messages (shows actual vs expected on failure).
+
+```typescript
+// ✅ Correct — single async call + single assertion
+await expect
+  .poll(() => comfyPage.nodeOps.getGraphNodesCount(), { timeout: 250 })
+  .toBe(0)
+
+// ❌ Avoid — nested expect inside toPass
+await expect(async () => {
+  expect(await comfyPage.nodeOps.getGraphNodesCount()).toBe(0)
+}).toPass({ timeout: 250 })
+```
+
+Reserve `toPass()` for blocks with multiple assertions or complex async logic that can't be expressed as a single polled value.
