feat(extension-api): test framework reorg + harness + content fill (I-TF.2/3/6)

- Layout reorg: nested __tests__/{v1,v2,migration}/BC.XX/ → flat
  __tests__/bc-XX.{v1,v2,migration}.test.ts (124 deletions, 121 fills)
- src/extension-api-v2/harness/: synthetic mini-ComfyApp + World stub
  with loadEvidenceSnippet() pulling R8 clone-and-grep excerpts
- vitest.extension-api.config.mts: adjusted for flat layout
- BC coverage: 41 categories × 3 stub types (v1/v2/migration)

Stacks on ext-api/i-foundation. Coworkers converting core extensions
should also branch off i-foundation, parallel to this PR.

-# 10. Deprecate Node-Level Serialization Control
-
-Date: 2026-05-12
-
-## Status
-
-Accepted
-
-## Context
-
-The v2 extension API initially included `node.on('beforeSerialize', handler)` as a migration path from v1 patterns like `node.onSerialize` and `nodeType.prototype.serialize` patching. This allowed extensions to:
-
-1. **Append extra fields** to the serialized node object
-2. **Transform the entire serialized object** via a replace function
-
-However, during design review (PR #12142), we questioned whether node-level serialization control is the right abstraction:
-
-### The Problem
-
-Node-level serialization control is fundamentally **wrong-layered**:
-
-- **Extension state should live in widgets**, not as arbitrary fields on the node
-- Widget-level `beforeSerialize` already handles all legitimate use cases
-- Node-level hooks encourage storing extension state in ad-hoc `node.properties` or custom fields, which:
-  - Breaks the clean separation between framework concerns and extension concerns
-  - Creates hidden dependencies between serialization format and extension behavior
-  - Makes migration and format evolution harder
-
-### v1 Usage Analysis
-
-Touch-point audit of `nodeType.prototype.serialize` and `node.onSerialize` patterns in the wild:
-
-| Use Case                    | Proper v2 Alternative                               |
-| --------------------------- | --------------------------------------------------- |
-| Store extension state       | Use widget values with `beforeSerialize`            |
-| Persist per-instance config | Use `widget.setOption()` → `widget_options` sidecar |
-| Add metadata for export     | Use a dedicated extension state widget              |
-| Transform output format     | Framework concern, not extension concern            |
-
-No use case requires node-level control that can't be better served by widget-level APIs.
-
-## Decision
-
-**Deprecate `node.on('beforeSerialize')`** — mark as `@deprecated` with clear guidance pointing to widget-level alternatives. Remove in v1.0.
-
-Widget-level serialization control (`widget.on('beforeSerialize')`) remains fully supported as the correct abstraction.
-
-### Migration Path
-
-Extensions currently using `node.on('beforeSerialize')` should:
-
-1. **Store state in widgets** instead of arbitrary node fields
-2. **Use `widget.on('beforeSerialize')`** to control serialization per-widget
-3. **Use `widget.setOption()`** for per-instance configuration
-
-Example migration:
-
-```ts
-// BEFORE (v1 / deprecated v2)
-node.on('beforeSerialize', (e) => {
-  e.data['my_extension_state'] = computeState()
-})
-
-// AFTER (recommended v2)
-const stateWidget = node.addWidget('STRING', '_my_state', '', {
-  hidden: true,
-  serialize: true
-})
-stateWidget.on('beforeSerialize', (e) => {
-  e.setSerializedValue(JSON.stringify(computeState()))
-})
-```
-
-### Implementation Steps
-
-1. Add `@deprecated` tag to `node.on('beforeSerialize')` with migration guidance
-2. Add console.warn when the deprecated event is used (dev mode only)
-3. Update documentation to recommend widget-level patterns
-4. Remove `NodeBeforeSerializeEvent` type and handler in v1.0
-
-## Consequences
-
-### Positive
-
-- **Cleaner architecture**: Extension state flows through widgets, the designed data channel
-- **Better debuggability**: Widget values are visible in workflow JSON at predictable locations
-- **Easier migration**: Future format changes only need to consider widget serialization
-- **Reduced API surface**: One less event type to maintain and document
-
-### Negative
-
-- **Migration burden**: Extensions using node-level serialization must refactor
-- **Potential edge cases**: Some exotic use cases may require workarounds
-
-### Risk Mitigation
-
-- Deprecation warning gives extension authors runway to migrate
-- Widget-level APIs are already more capable than node-level alternatives
-- The `@deprecated` tag and docs provide clear migration path
-
-## Notes
-
-This decision was made during design review of PR #12142 (ext-api foundation). See `design-review-12142.md` Topic 11 for the full discussion thread.
-
-Related decisions:
-
-- Widget-level `beforeSerialize` remains the primary extension serialization hook
-- `setSerializeEnabled()` remains for simple static opt-out cases

-# 11. Immutability Enforcement via Fresh Copies
-
-Date: 2026-05-12
-
-## Status
-
-Accepted
-
-## Context
-
-The extension API exposes collection-returning methods like `widgets()`, `inputs()`, `outputs()`, and object-returning methods like `getProperties()`. These methods need immutability guarantees to prevent extensions from accidentally or intentionally mutating internal state.
-
-### The Problem
-
-Without runtime immutability enforcement:
-
-- Extensions could push items into `widgets()` array, corrupting internal state
-- Mutations to returned objects would silently affect internal data
-- Debugging would be difficult — state corruption could surface far from the mutation site
-- Internal framework code might inadvertently rely on returned arrays being stable
-
-TypeScript's `readonly` modifier and JSDoc annotations provide compile-time protection, but:
-
-- JavaScript consumers have no protection
-- Type assertions can bypass readonly
-- Agent-generated code may not respect type hints
-
-### Options Considered
-
-| Option                   | Pros                                                      | Cons                                                     |
-| ------------------------ | --------------------------------------------------------- | -------------------------------------------------------- |
-| **1. `Object.freeze()`** | Runtime immutability, throws on mutation                  | Performance overhead, nested objects need deep freeze    |
-| **2. Return fresh copy** | Simple, functional style, no mutation affects source      | Slight memory overhead, multiple calls = multiple arrays |
-| **3. Proxy wrapper**     | Helpful error messages, can intercept specific operations | Complexity, performance overhead, harder to debug        |
-| **4. TypeScript only**   | Zero runtime cost                                         | No protection for JS consumers, can be bypassed          |
-| **5. Private fields**    | True encapsulation                                        | Blocks read access too, not suitable for APIs            |
-
-## Decision
-
-**Return fresh copies** (Option 2) for all collection-returning and object-returning methods in the extension API.
-
-### Implementation Pattern
-
-```ts
-// CORRECT: Return fresh copy
-widgets(): readonly WidgetHandle[] {
-  const container = world.getComponent(nodeId, WidgetComponentContainer)
-  return (container?.widgetIds ?? []).map(createWidgetHandle)
-  // Each call creates new array — mutations don't affect internal state
-}
-
-getProperties(): Record<string, unknown> {
-  return { ...world.getComponent(nodeId, NodeTypeKey)?.properties }
-  // Shallow copy — mutations don't affect source
-}
-```
-
-### Scope
-
-Apply this pattern to:
-
-- `NodeHandle.widgets()` — returns fresh `WidgetHandle[]`
-- `NodeHandle.inputs()` — returns fresh `SlotInfo[]`
-- `NodeHandle.outputs()` — returns fresh `SlotInfo[]`
-- `NodeHandle.getProperties()` — returns fresh `Record<string, unknown>`
-- `WidgetHandle` methods that return objects (if any)
-- Any future collection/object-returning methods
-
-### Internal Callers
-
-Framework-internal code must also use mutation APIs rather than mutating returned collections:
-
-```ts
-// WRONG: Mutating returned array
-const widgets = node.widgets()
-widgets.push(newWidget) // No effect on node!
-
-// CORRECT: Use mutation API
-node.addWidget(type, name, value, options)
-```
-
-## Consequences
-
-### Positive
-
-- **True immutability**: Mutations to returned data never affect internal state
-- **Predictable behavior**: Each call returns fresh data reflecting current state
-- **Simple mental model**: "This is your copy, do what you want with it"
-- **JavaScript-safe**: Works regardless of TypeScript types
-
-### Negative
-
-- **Memory overhead**: Multiple calls create multiple arrays (usually negligible)
-- **No mutation detection**: Extensions silently get isolated copies, won't know their mutations are ignored
-- **Fresh reference each call**: Cannot use `===` to detect changes (use deep comparison or events)
-
-### Mitigations
-
-- Document that returned collections are snapshots
-- Use events (`valueChange`, `propertyChange`) to observe changes
-- The memory overhead is negligible for typical widget/slot counts
-
-## Notes
-
-This decision was made during design review of PR #12142 (ext-api foundation). See `design-review-12142.md` Topic 14 for the full discussion thread.
-
-The alternative of `Object.freeze()` was rejected because:
-
-- It requires deep freezing for nested objects
-- Performance overhead for each call
-- Fresh copies achieve the same goal more simply

-# 12. Pure Function Loader Pattern for Extension Registration
-
-Date: 2026-05-12
-
-## Status
-
-Accepted
-
-## Context
-
-The v2 extension API needs a mechanism for extensions to register themselves with the runtime. Two broad approaches exist:
-
-### Side-Effect Registration (Vue 2 Plugin Pattern)
-
-```ts
-// Extension self-registers at import time
-import { app } from '@comfyorg/core'
-
-app.use({
-  install(app) {
-    app.component('MyWidget', MyWidget)
-    app.directive('my-directive', myDirective)
-  }
-})
-```
-
-Problems:
-
-- **Import order matters**: If extension A depends on extension B being registered first, import order must be carefully managed
-- **Hard to test**: Side effects at import time make mocking difficult; tests must manipulate module cache
-- **Hard to tree-shake**: Bundlers can't eliminate unused extensions — the import executes
-- **Timing coupling**: Registration and activation are conflated; can't collect extensions first, then activate later
-
-### Pure Function + Loader Pattern
-
-```ts
-// Extension declares intent — no side effects
-export default defineNode({
-  name: 'my-extension',
-  nodeTypes: ['MyNode'],
-  nodeCreated(handle) {
-    // ...
-  }
-})
-
-// App bootstrap activates all registered extensions
-startExtensionSystem()
-```
-
-## Decision
-
-**Adopt the pure function + loader pattern** for v2 extension registration.
-
-### Implementation
-
-```ts
-// Extension Registry (data collection only)
-const nodeExtensions: NodeExtensionOptions[] = []
-
-export function defineNode(options: NodeExtensionOptions): void {
-  nodeExtensions.push(options)
-}
-
-// Loader (activation)
-export function startExtensionSystem(): void {
-  const world = getWorld()
-  watch(
-    () => world.entitiesWith(NodeTypeKey),
-    (nodeEntityIds) => {
-      for (const id of nodeEntityIds) {
-        mountExtensionsForNode(id)
-      }
-    },
-    { immediate: true }
-  )
-}
-```
-
-### Key Properties
-
-1. **Pure registration**: `defineNode()` has no side effects beyond pushing to an array. It doesn't touch the World, DOM, or any reactive state.
-
-2. **Centralized activation**: `startExtensionSystem()` is called exactly once during app bootstrap. This single entry point controls when the extension system "goes live".
-
-3. **Reactive mounting**: The loader watches the World for entity changes. Extensions are mounted/unmounted in response to ECS state, not imperative calls.
-
-4. **Order independence**: Extensions can be defined in any order. The loader sorts by name (lexicographic, see D10b) for deterministic execution.
-
-### Registration Flow
-
-```
-Extension files         App bootstrap           World

-## Consequences
-
-### Positive
-
-- **Testability**: Extensions are plain objects; tests can construct them without side effects. `_clearExtensionsForTesting()` resets state between tests.
-- **Tree-shakeable**: Bundlers can eliminate unused extension files if their exports are never referenced.
-- **Order independent**: No import order bugs — the loader handles activation order.
-- **Lazy activation**: Registration is instant; activation only happens when `startExtensionSystem()` is called.
-- **SSR friendly**: Pure functions don't execute browser-only code at import time.
-
-### Negative
-
-- **Manual bootstrap**: App must call `startExtensionSystem()` — forgetting it silently disables extensions.
-- **Two-step mental model**: Developers must understand "register" vs "activate" phases.
-
-### Mitigations
-
-- App bootstrap is a well-defined location; the call is hard to miss.
-- Clear documentation and starter templates include the bootstrap call.
-- Dev-mode warnings if extensions are defined but the system never starts.
-
-## Notes
-
-This pattern aligns with modern framework conventions:
-
-- **Vite plugins**: `vite.config.ts` collects plugins as an array; Vite activates them at build time.
-- **Vue 3 Composition API**: `setup()` returns reactive state; the framework activates it.
-- **React hooks**: Pure functions declare effects; React schedules them.
-
-The key insight is separating **declaration** (what do I want?) from **execution** (make it happen). This separation enables testing, lazy loading, and predictable behavior.

+# Names That Must Agree Across Layers
+
+**Task:** DOC1.E6  
+**Date:** 2026-05-08  
+**Patterns cross-walked:** S2.N16 (widget array access), S13.SC1 (ComfyNodeDef inspection), S15.OS1 (dynamic output mutation)
+
+This appendix enumerates the terms that span at least two of the four layers — Python backend, v1 frontend (`ComfyExtension`/LiteGraph), v2 extension API (`NodeHandle`/`WidgetHandle`), and ECS World components — and calls out real inconsistencies where the same concept is named differently or the semantics diverge. Future contributors who rename or refactor any of these terms must propagate the change across all layers listed.
+
+---
+
+## Layers
+
+| Layer | Owner | Primary source |
+|-------|-------|---------------|
+| **Python backend** | ComfyUI server | `NODE_CLASS_MAPPINGS`, `INPUT_TYPES`, `RETURN_TYPES` |
+| **v1 frontend** | LiteGraph / ComfyExtension | `src/types/comfy.ts`, `src/schemas/nodeDefSchema.ts`, `LGraphNode.ts` |
+| **v2 extension API** | This project | `src/extension-api/node.ts`, `src/extension-api/widget.ts` |
+| **ECS World** | Alex's branch (PR #11939) | `src/services/extension-api-service.ts` (stubs), `@/world/entityIds` |
+
+---
+
+## Term 1 — Node class identifier (`class_type` / `type` / `comfyClass`)
+
+**What it is:** The string that identifies which Python class backs a node. Used to look up `object_info`, serialize the prompt, and match `INPUT_TYPES` definitions.
+
+| Layer | Name | Value example | Notes |
+|-------|------|--------------|-------|
+| Python backend | Python class name | `'KSampler'` | The class registered in `NODE_CLASS_MAPPINGS` |
+| Execution prompt JSON (API format) | `class_type` | `"class_type": "KSampler"` | Key in the flat prompt dict |
+| UWF backend spec | `class_type` | `"class_type": "KSampler"` | Unchanged from API format (per `uwf-backend-data-model.md`) |
+| `ComfyNodeDef` (v1 schema) | `name` | `nodeData.name === 'KSampler'` | The `name` field in the server's `/object_info` response |
+| `LGraphNode` (v1) | `node.type` | `node.type === 'KSampler'` | LiteGraph's class string; set at registration |
+| v2 `NodeHandle` | `handle.type` | `handle.type === 'KSampler'` | `readonly type: string` in `src/extension-api/node.ts:260` |
+| v2 `NodeHandle` | `handle.comfyClass` | `handle.comfyClass === 'KSampler'` | `readonly comfyClass: string` in `src/extension-api/node.ts:269` |
+| ECS `NodeTypeData` component | `type` + `comfyClass` | both fields | Stub in `extension-api-service.ts:61–63` |
+
+**⚠ Inconsistency — `type` vs `comfyClass`:** v2 `NodeHandle` exposes **both** `type` and `comfyClass` because for most nodes they are equal, but for virtual/reroute nodes `type` is the LiteGraph registration string while `comfyClass` is the actual Python class backing the node. Extensions that compare against ComfyUI node names should always use `comfyClass`. Extensions that filter by LiteGraph registration (for `nodeTypes:` filter in `defineNodeExtension`) should use `type`. The distinction must be preserved — collapsing them back to one field would break reroute/virtual-node detection.
+
+**Rule:** `class_type` (wire format, Python, UWF) = `comfyClass` (v2 API) = `name` in `ComfyNodeDef` = `node.type` in LiteGraph for non-virtual nodes.
+
+---
+
+## Term 2 — Node display name (`display_name` / `title`)
+
+**What it is:** The human-readable label shown in the node header and search results. Distinct from the class identifier.
+
+| Layer | Name | Notes |
+|-------|------|-------|
+| Python backend | `NODE_DISPLAY_NAME_MAPPINGS[class]` (optional) | If absent, falls back to the class name |
+| `ComfyNodeDef` (v1 schema) | `display_name` | `nodeData.display_name` — always a string per zod schema (`src/schemas/nodeDefSchema.ts:279`) |
+| `LGraphNode` (v1) | `node.title` | Set during `nodeCreated`; extensions mutate `node.title` directly to rename nodes |
+| v2 `NodeHandle` | `handle.title` (getter) + `handle.setTitle(s)` | `src/extension-api/node.ts:304–315`; accessor pair per D3.3/D6 hybrid rule |
+| ECS `NodeVisualData` component | `title` | Field name consistent with LiteGraph |
+
+**No inconsistency.** `display_name` lives only in the schema/backend layer; `title` is the runtime/frontend term. The two layers don't overlap. Extension authors should use `handle.setTitle()` in v2; `node.title =` is the v1 equivalent. Both are stable.
+
+---
+
+## Term 3 — Widget name (`name` / `input_name` / `widget.name`)
+
+**What it is:** The stable per-node-instance identifier for a widget slot. Used as the key in `widgets_values_named`, `promoted_inputs`, and for `WidgetHandle` lookup.
+
+| Layer | Name | Notes |
+|-------|------|-------|
+| Python backend `INPUT_TYPES` | Dict key (e.g. `'seed'`, `'steps'`) | The name as declared in the Python class |
+| UWF `promoted_inputs` | `input_name` | `{ node_id, input_name, display_name }` — snake_case to match Python origin |
+| UWF `spec.nodes.{id}.inputs` | Named key in the inputs object | e.g. `"seed": { "value": 123, "link": null }` |
+| v1 `LGraphNode.widgets` | `widget.name` | `widget.name === 'seed'` — used in `node.widgets.find(w => w.name === ...)` (S2.N16 pattern) |
+| v1 `node.widgets` iteration | position index (implicit) | `widgets_values` positional array — the root cause of widget shift bugs (S17.WV1) |
+| v2 `NodeHandle.widget(name)` | `name` argument | Lookup by name, not position (`src/extension-api/node.ts:383`) |
+| v2 `NodeHandle.addWidget(type, name, ...)` | `name` parameter | `src/extension-api/node.ts:396–403`; stable key for the widget's lifetime |
+| v2 `WidgetHandle.name` | `readonly name: string` | `src/extension-api/widget.ts:277` — "stable within the node's lifetime" |
+| ECS `WidgetComponentSchema` | `name` field (inferred) | Widget schema component expected to carry `name` per `widgetComponents` import |
+
+**⚠ Inconsistency — positional array vs. named:** v1 serialization stores widget values as a positional array (`widgets_values: [123, 20, 7.5]`). v2 API and UWF both use `name` as the stable key. The bridge is Austin's PR #10392 (`widgets_values_named`). Until that merges, any code that reads `node.widgets[i]` by index is fragile; code that reads `widget.name` is UWF-safe. The v2 `WidgetHandle` **must** be looked up by name, never by index — this is enforced by the API shape.
+
+**Rule:** Always use the Python-declared input name as the canonical widget identifier. Never use position. `widget.name` (v1) = `name` parameter (v2 addWidget) = `input_name` (UWF wire format).
+
+---
+
+## Term 4 — Widget type string (`type` / `widgetType` / widget constructor key)
+
+**What it is:** The string describing what kind of widget a slot is (e.g. `'INT'`, `'STRING'`, `'COMBO'`, `'IMAGE'`). Controls which widget constructor is used and which validation rules apply.
+
+| Layer | Name | Notes |
+|-------|------|-------|
+| Python backend | Return value of `INPUT_TYPES()` tuple: first element | e.g. `("INT", {"default": 42})` — the type string |
+| `ComfyNodeDef` / `InputSpec` | Type string as zod-inferred from the schema | `INPUT_TYPES['required']['steps'] = ['INT', {...}]` |
+| `zBaseInputOptions` | `widgetType` field (optional override) | `src/schemas/nodeDefSchema.ts:33` — overrides the slot type for widget selection; rare |
+| v1 `getCustomWidgets` return | Record key | `{ MY_WIDGET: constructor }` — extension-registered type strings |
+| v1 `node.addWidget(type, ...)` | `type` first arg | The LiteGraph widget constructor key |
+| v2 `NodeHandle.addWidget(type, name, ...)` | `type` first arg | `src/extension-api/node.ts:395, 403` |
+| v2 `WidgetHandle.type` | `readonly type: string` | `src/extension-api/widget.ts` line ~280 |
+| ECS `WidgetComponentSchema` | `type` field | Expected to match the Python-declared type string |
+
+**⚠ Inconsistency — `widgetType` override:** The `widgetType` field in `zBaseInputOptions` is an override that makes the frontend render a different widget than the Python type implies. Extensions that inspect `nodeData.input.required[name][1].widgetType` to determine rendering (S13.SC1 pattern) must check this field **before** using the slot's primary type. The v2 `ComfyNodeDef`-inspection helper (`ctx.inspectNodeDef`) must resolve this correctly — it cannot just return `InputSpec[0]` (the Python type) as `widgetType`.
+
+**Rule:** Python type string = v1 `widget.type` = v2 `WidgetHandle.type` = `widgetType` override if present (takes precedence).
+
+---
+
+## Term 5 — Slot type string (connection type / `'IMAGE'`, `'LATENT'`, etc.)
+
+**What it is:** The type label on a node's input/output slot that governs which connections are valid. Distinct from widget type (a slot may be a pure connection point with no widget).
+
+| Layer | Name | Notes |
+|-------|------|-------|
+| Python backend | `RETURN_TYPES` tuple element | e.g. `RETURN_TYPES = ('IMAGE', 'MASK')` |
+| Python backend `INPUT_TYPES` | First element of required/optional tuple | `'IMAGE'` means "must receive an IMAGE connection" |
+| UWF `spec.nodes.{id}.outputs` | `{ "name": "IMAGE" }` per output | Output type declarations (new in UWF — not in old API format) |
+| v1 `LGraphNode` slot | `slot.type` | String on the slot object; extensions read/mutate via S15.OS1 |
+| v1 `node.addInput(name, type)` | `type` second arg | e.g. `node.addInput('mask', 'MASK')` |
+| v1 `node.addOutput(name, type)` | `type` second arg | S15.OS1 pattern |
+| v2 `SlotInfo` | `readonly type: string` | `src/extension-api/node.ts:82–83` |
+| v2 slot events | `event.slot.type` | Available in `onSlotConnected`, `onSlotDisconnected` |
+
+**⚠ Inconsistency — dynamic mutation (S15.OS1):** v1 allows `slot.type = 'IMAGE'` and `node.outputs[i].type = newType` at runtime. v2 restricts this: output types must be declared in `INPUT_TYPES` / schema; runtime mutation is only via `node.declareOutputs(spec)` (proposed, not yet implemented). This is an intentional breaking change. The UWF spec formalizes this by requiring `spec.nodes.{id}.outputs` to be declared at save time, not derived from runtime state.
+
+**Rule:** Slot type strings are uppercase by convention (matching Python `RETURN_TYPES`). v2 enforces schema-declaration; mutation-at-runtime is deprecated.
+
+---
+
+## Term 6 — Node output name (`output_name` / `RETURN_NAMES`)
+
+**What it is:** Optional human-readable names for a node's output slots. Not the type — the label shown on the output connector.
+
+| Layer | Name | Notes |
+|-------|------|-------|
+| Python backend | `RETURN_NAMES` class attribute | e.g. `RETURN_NAMES = ('upscaled_image', 'mask')` — optional |
+| `ComfyNodeDef` schema | `output_name` | `z.array(z.string()).optional()` in `src/schemas/nodeDefSchema.ts:275` |
+| v1 `LGraphNode` | `output.name` | String on the slot object; `node.outputs[i].name` |
+| v2 `SlotInfo` | `readonly name: string` | `src/extension-api/node.ts:80–81` — same field name |
+
+**No inconsistency.** `RETURN_NAMES` → `output_name` in the schema → `slot.name` at runtime. All three refer to the same string. Field name shifts from snake_case (`output_name`) in the schema to camelCase-neutral (`name`) on the slot object — consistent with the rest of the frontend.
+
+---
+
+## Term 7 — Extension name (`ComfyExtension.name` / `ExtensionOptions.name`)
+
+**What it is:** The unique identifier for an extension used for hook ordering (D10b), scope registry keys, deprecation telemetry, and conflict detection.
+
+| Layer | Name | Notes |
+|-------|------|-------|
+| v1 `ComfyExtension` | `name: string` | Required field; `src/types/comfy.ts:108`; typically a dotted namespace like `'Comfy.Sidebar'` |
+| v2 `ExtensionOptions` | `name: string` | Required field; `src/extension-api/lifecycle.ts`; same semantic |
+| ECS scope registry | `extensionName` | Key component of `NodeInstanceScope`; used in `${extensionName}:${nodeEntityId}` scope key |
+| D6 telemetry | `apiVersion` | Separate field added by I-EXT.3 to `ExtensionOptions` for version tracking — not a replacement for `name` |
+
+**No inconsistency.** Same field name and semantics across v1 and v2. The scope registry key format is `${extensionName}:${nodeEntityId}` — both components must be stable.
+
+**Rule:** Extension names should follow the dotted-namespace convention (e.g. `'MyPublisher.MyExtension'`) to avoid collisions. This is currently advisory, not enforced.
+
+---
+
+## Term 8 — Node input display name (`display_name` / widget label)
+
+**What it is:** The label shown next to the widget in the UI. Distinct from the internal `name` (key) used for serialization.
+
+| Layer | Name | Notes |
+|-------|------|-------|
+| Python backend | `display_name` in input options dict | `INPUT_TYPES()['required']['steps'] = ['INT', {'display_name': 'Steps'}]` |
+| `zBaseInputOptions` schema | `display_name: z.string().optional()` | `src/schemas/nodeDefSchema.ts:27` |
+| UWF `promoted_inputs` | `display_name` field | `{ node_id, input_name, display_name }` — the UI label for app-mode promoted inputs |
+| v1 `widget` | `widget.label` | Optional; falls back to `widget.name` if absent. Inspected in S2.N16 patterns |
+| v2 `WidgetHandle` | `label` getter | `src/extension-api/widget.ts:355` — "Defaults to the widget name" |
+
+**No inconsistency** in naming — all layers call it `display_name` (schema/wire) or `label` (runtime). The two forms are consistent: `display_name` is the static schema-declared label; `label` is the runtime-settable display string. v2 exposes `label` as a settable accessor; the Python-declared `display_name` becomes its initial value.
+
+---
+
+## Summary: real inconsistencies to track
+
+| # | Inconsistency | Risk | Resolution |
+|---|--------------|------|-----------|
+| 1 | `type` vs `comfyClass` on `NodeHandle` — two fields, must not collapse | Medium | Document: use `comfyClass` for Python identity, `type` for LiteGraph registration. Enforced by distinct fields. |
+| 2 | Widget identity: positional index (v1 `widgets_values`) vs name key (v2 / UWF) | **HIGH** | Bridge: Austin's PR #10392 (`widgets_values_named`). v2 `WidgetHandle` is name-only. Never look up by position in v2 code. |
+| 3 | `widgetType` override in `InputSpec` takes precedence over slot type for rendering | Medium | `ctx.inspectNodeDef` must resolve `widgetType` before returning slot type. Do not skip this field. |
+| 4 | Slot type mutation (S15.OS1): `slot.type = X` is valid v1, banned in v2/UWF | Medium | v2 must not expose a `setType()` mutator on `SlotInfo`. Schema-declare outputs; UWF enforces at save time. |
+
+---
+
+## Cross-references
+
+- **S2.N16** — widget array iteration/mutation (`node.widgets[i]`, `node.widgets.find(w => w.name === ...)`): the `name` field is the stable key; position is not. v2 forces name-based lookup.
+- **S13.SC1** — `ComfyNodeDef` inspection: callers must resolve `widgetType` override (Term 4) and understand `display_name` vs runtime `label` (Term 8). The `ctx.inspectNodeDef` typed helper (D4 G1 BLOCKER) wraps this correctly.
+- **S15.OS1** — dynamic output mutation: slot `type` strings are the agreed layer (Term 5), but v1 allows mutation that v2/UWF forbids. Track in I-PG.B2 as `strangler-bridge` until UWF Phase 3 covers output schema declaration.
+- **UWF backend data model** — `class_type`, `input_name`, `display_name` snake_case keys mirror Python origin. v2 API uses camelCase (`comfyClass`, widget `name`, widget `label`) per JS convention. No semantic difference; only case convention changes at the API boundary.

-# Research: Canvas vs Client/Pixel Coordinate Usage
-
-Date: 2026-05-12
-
-## Question
-
-How should the extension API handle coordinate systems? Should it expose canvas coordinates, screen/client coordinates, or both?
-
-## Coordinate Systems in ComfyUI
-
-### 1. Canvas Space (Logical Units)
-
-Node positions and sizes are in canvas logical units:
-
-- Independent of zoom/pan
-- `[0, 0]` is the canvas origin
-- Moving a node to `[100, 200]` places it at canvas position (100, 200) regardless of viewport state
-
-### 2. Screen/Client Space (Pixels)
-
-DOM elements use pixel coordinates relative to the viewport:
-
-- Affected by zoom/pan/scroll
-- `clientX`/`clientY` from mouse events
-- `getBoundingClientRect()` returns pixel values
-
-### 3. Widget Height (Pixels)
-
-DOM widgets reserve height in pixels:
-
-```ts
-addDOMWidget({ name: 'preview', element: img, height: 200 }) // 200px
-```
-
-## Current Extension API
-
-| Method                     | Coordinate System | Notes                                     |
-| -------------------------- | ----------------- | ----------------------------------------- |
-| `getPosition()`            | Canvas            | Returns `[x, y]` in canvas units          |
-| `setPosition()`            | Canvas            | Accepts `[x, y]` in canvas units          |
-| `getSize()`                | Canvas            | Returns `[width, height]` in canvas units |
-| `setSize()`                | Canvas            | Accepts `[width, height]` in canvas units |
-| `addDOMWidget({ height })` | Pixels            | Reserved height in pixels                 |
-| `widget.setHeight(px)`     | Pixels            | Widget height in pixels                   |
-
-## Analysis
-
-### When Extensions Need Canvas Coordinates
-
-1. **Node positioning**: Placing nodes relative to each other
-2. **Layout algorithms**: Auto-arranging nodes in a pattern
-3. **Collision detection**: Checking if nodes overlap
-
-### When Extensions Need Screen Coordinates
-
-1. **Custom overlays**: Drawing UI at a specific screen location
-2. **Drag-and-drop from external sources**: Converting mouse position to canvas position
-3. **Context menus**: Positioning menus near the cursor
-
-### Current State
-
-The extension API currently exposes:
-
-- **Canvas coordinates** for node position/size — appropriate, as these are logical values
-- **Pixel values** for DOM widget height — appropriate, as these are DOM measurements
-
-**Missing**: No conversion helpers between canvas and screen coordinates.
-
-## Recommendation
-
-**The current approach is appropriate.** Extensions that manipulate node positions should work in canvas space. This is the natural abstraction — extensions shouldn't need to account for zoom/pan when laying out nodes.
-
-### For Advanced Cases
-
-Extensions needing coordinate conversion (e.g., custom overlays) should either:
-
-1. **Use LiteGraph's existing transform utilities** (available on `app.canvas`)
-2. **Access the transform state** via a future canvas API (not part of node/widget handles)
-
-### Why Not Expose Conversion Helpers on NodeHandle?
-
-- **Wrong abstraction level**: Coordinate conversion is a canvas concern, not a node concern
-- **State dependency**: Conversion requires current zoom/pan state, which changes frequently
-- **Rare use case**: Most extensions work entirely in canvas space
-
-## Future Considerations
-
-If multiple extensions need coordinate conversion, consider:
-
-1. **Canvas API**: `canvas.screenToCanvas(point)` / `canvas.canvasToScreen(point)`
-2. **Events with both coordinates**: `positionChanged` could include both canvas and screen positions
-
-For now, no changes are needed — the current API serves the common cases well.

-# Research: DOM Widget Convergence with Base Widget
-
-Date: 2026-05-12
-
-## Question
-
-Should DOM widgets be unified with base widgets, or kept as a separate concept?
-
-## Current State
-
-### Creation APIs
-
-- `node.addWidget(type, name, value, options)` — creates a standard widget
-- `node.addDOMWidget({ name, element, height })` — creates a DOM-backed widget
-
-### Internal Implementation
-
-Both use the same underlying `CreateWidget` command:
-
-```ts
-addWidget(type, name, defaultValue, options) {
-  return dispatch({ type: 'CreateWidget', widgetType: type, ... })
-}
-
-addDOMWidget(opts) {
-  return dispatch({ type: 'CreateWidget', widgetType: 'DOM', ... })
-}
-```
-
-DOM widgets are just widgets with `widgetType: 'DOM'` and an element reference.
-
-### Shared WidgetHandle Interface
-
-Both widget types share the same `WidgetHandle` interface:
-
-| Method                           | Standard Widget | DOM Widget              |
-| -------------------------------- | --------------- | ----------------------- |
-| `entityId`, `name`, `widgetType` | ✓               | ✓                       |
-| `getValue()` / `setValue()`      | ✓ (scalar)      | ✓ (often unused)        |
-| `isHidden()` / `setHidden()`     | ✓               | ✓                       |
-| `isDisabled()` / `setDisabled()` | ✓               | ✓                       |
-| `setHeight(px)`                  | no-op           | ✓ (updates reservation) |
-| `on('valueChange')`              | ✓               | ✓                       |
-| `getOption()` / `setOption()`    | ✓               | ✓                       |
-
-## Analysis
-
-### Arguments FOR Full Convergence
-
-1. **Single mental model**: Extensions learn one widget concept, not two.
-2. **Consistent behavior**: All widgets appear in `node.widgets()`, serialize the same way.
-3. **Simpler API surface**: Fewer methods to document and maintain.
-
-### Arguments FOR Keeping Separate APIs
-
-1. **Different ergonomics**: Standard widgets are data-driven (name, value, options); DOM widgets are element-driven (pass an HTMLElement).
-2. **Type safety**: `addDOMWidget` can require `element: HTMLElement` at compile time; merging would make it optional with runtime checks.
-3. **Clear intent**: Separate APIs signal different use cases.
-
-## Recommendation
-
-**Keep the current partial convergence.** The implementation is unified (`CreateWidget` command), but the creation APIs remain separate for ergonomic reasons.
-
-### Rationale
-
-1. **Creation differs, usage is unified.** Extensions create DOM widgets differently (need an element), but interact with them the same way (via `WidgetHandle`).
-
-2. **Type safety is valuable.** `addDOMWidget({ element })` is clearer than `addWidget('DOM', name, null, { element })`.
-
-3. **Already well-integrated.** DOM widgets appear in `node.widgets()`, get the same events, and use the same serialization infrastructure.
-
-### What "Convergence" Means Here
-
-The widgets are already converged at:
-
-- **Entity level**: Same `WidgetEntityId` brand
-- **Interface level**: Same `WidgetHandle` type
-- **Command level**: Same `CreateWidget` command internally
-
-The APIs are intentionally separate at:
-
-- **Creation level**: `addWidget` vs `addDOMWidget`
-
-This is the right split — unified where it matters (runtime behavior), separate where it improves DX (creation ergonomics).
-
-## Future Considerations
-
-If we add more widget creation patterns (e.g., `addCanvasWidget`, `addThreeJSWidget`), we might consider:
-
-1. **Factory pattern**: `node.widgets.create('DOM', { element })` / `node.widgets.create('INT', { min, max })`
-2. **Builder pattern**: `node.addWidget('DOM').withElement(el).withHeight(200).build()`
-
-For now, two explicit methods (`addWidget`, `addDOMWidget`) serve the common cases well.

-# Research: Identity Encapsulation in the Extension API
-
-Date: 2026-05-12
-
-## Question
-
-When do extensions need access to raw entity IDs (`NodeEntityId`, `WidgetEntityId`, `SlotEntityId`)? Should these be exposed or hidden?
-
-## Current State
-
-The v2 extension API exposes entity IDs as read-only properties:
-
-```ts
-interface NodeHandle {
-  readonly entityId: NodeEntityId
-  // ...
-}
-
-interface WidgetHandle {
-  readonly entityId: WidgetEntityId
-  // ...
-}
-
-interface SlotInfo {
-  readonly entityId: SlotEntityId
-  // ...
-}
-```
-
-All IDs are **branded types** to prevent accidental mixing at compile time.
-
-## Use Cases for Raw Entity IDs
-
-### 1. Per-Instance State Mapping
-
-Extensions maintaining external state per node:
-
-```ts
-const nodeCache = new Map<NodeEntityId, CachedData>()
-
-defineNode({
-  name: 'my-cache-extension',
-  nodeCreated(handle) {
-    nodeCache.set(handle.entityId, computeExpensiveData())
-    onNodeRemoved(() => nodeCache.delete(handle.entityId))
-  }
-})
-```
-
-### 2. Logging and Debugging
-
-```ts
-node.on('executed', (e) => {
-  console.log(`[${node.entityId}] Output:`, e.output)
-})
-```
-
-### 3. Inter-Extension Communication
-
-Extensions that need to coordinate across multiple nodes:
-
-```ts
-// Extension A stores data
-globalState.set(nodeA.entityId, data)
-
-// Extension B retrieves it
-const data = globalState.get(nodeB.entityId)
-```
-
-### 4. External System Interop
-
-Extensions integrating with analytics, debugging tools, or external services that need stable node identifiers.
-
-## Analysis
-
-### Arguments FOR Exposing Entity IDs
-
-1. **Legitimate need exists** — The use cases above are real and common.
-2. **Branded types prevent misuse** — Can't accidentally use `NodeEntityId` where `WidgetEntityId` is expected.
-3. **Read-only access** — Extensions can't mutate the ID or corrupt internal state.
-4. **Opaque value** — The format (`node:<graphUuid>:<localId>`) is an implementation detail; extensions should treat it as an opaque string.
-
-### Arguments AGAINST Exposing Entity IDs
-
-1. **Format coupling** — Extensions might parse the ID string and break if format changes.
-2. **Internal detail leakage** — Knowing the ID scheme reveals ECS architecture.
-3. **Future migration friction** — Changing ID representation requires careful deprecation.
-
-### Mitigations
-
-- **Document as opaque**: JSDoc clearly states IDs are opaque, not to be parsed.
-- **Branded types**: TypeScript prevents misuse across entity categories.
-- **Phase A format**: Current format includes graph UUID + local ID; this can evolve via semver.
-
-## Recommendation
-
-**Keep exposing entity IDs.** The use cases are legitimate, the branded types provide safety, and the read-only nature limits risk. Document that IDs are opaque strings — extensions should never parse or construct them.
-
-### Guidelines for Extension Authors
-
-1. **Use IDs only for keying** — Maps, Sets, logging, external system references.
-2. **Never parse IDs** — The format is an implementation detail subject to change.
-3. **Prefer handles over IDs** — When passing references between functions, use the handle object, not the raw ID.
-4. **Clean up on removal** — Always use `onNodeRemoved()` to clean up Maps keyed by entityId.
-
-## Future Considerations
-
-If the ID format needs to change significantly, the branded types allow us to:
-
-1. Introduce a new branded type (e.g., `NodeEntityIdV2`)
-2. Deprecate the old ID with migration guidance
-3. Keep both supported during a transition period

-# Research: Serialization Context Simplification
-
-Date: 2026-05-12
-
-## Question
-
-Can the serialization context be simplified from 4 values to fewer?
-
-Current contexts:
-
-- `'workflow'` — saving workflow to disk
-- `'prompt'` — queueing a run (API call)
-- `'clone'` — copy/paste operation
-- `'subgraph-promote'` — widget becoming subgraph IO
-
-## Use Case Analysis
-
-### Context: 'workflow'
-
-**Purpose**: Full persistence of user's work.
-
-**What extensions need**: Serialize everything the user configured.
-
-**Example**: A widget storing user preferences needs to include all settings.
-
-### Context: 'prompt'
-
-**Purpose**: Sending data to the backend for execution.
-
-**What extensions need**:
-
-- Transform values (dynamic prompts → resolved text)
-- Skip preview-only widgets
-- Materialize async sources (webcam → frame data)
-
-**Example**:
-
-```ts
-widget.on('beforeSerialize', async (e) => {
-  if (e.context === 'prompt') {
-    e.setSerializedValue(await captureFrame())
-  }
-})
-```
-
-### Context: 'clone'
-
-**Purpose**: Copy/paste should yield independent copy.
-
-**What extensions need**: Reset instance-specific state while keeping user settings.
-
-**Example**: A random seed widget might want a new seed on paste.
-
-### Context: 'subgraph-promote'
-
-**Purpose**: Widget becomes an input/output on a subgraph.
-
-**What extensions need**: Convert internal representation to subgraph IO format.
-
-**Example**: Internal state becomes an exposed parameter.
-
-## Simplification Options
-
-### Option A: Keep All 4 (Current State)
-
-| Pro                                      | Con               |
-| ---------------------------------------- | ----------------- |
-| Each context has distinct semantics      | 4 cases to handle |
-| Type system enforces valid values        | More complex API  |
-| Clear intent for each serialization path |                   |
-
-### Option B: Collapse to 2 ('persist' | 'execute')
-
-```ts
-context: 'persist' | 'execute'
-// 'persist' = workflow, clone, subgraph-promote
-// 'execute' = prompt
-```
-
-| Pro                                        | Con                             |
-| ------------------------------------------ | ------------------------------- |
-| Simpler mental model                       | Loses clone/promote distinction |
-| Most extensions only care about this split | Can't reset seed on clone       |
-
-### Option C: Remove Context Entirely
-
-Extensions always transform regardless of context. The framework handles differences.
-
-| Pro                          | Con                                            |
-| ---------------------------- | ---------------------------------------------- |
-| Simplest API                 | Loses control for edge cases                   |
-| Framework handles all nuance | Some extensions need context-specific behavior |
-
-## Recommendation
-
-**Keep all 4 contexts.** The use cases are genuinely different:
-
-1. **workflow vs prompt**: Very common distinction. Dynamic prompts only process on prompt; preview widgets skip prompt. This is the most important split.
-
-2. **clone**: Less common, but needed for stateful widgets (random seeds, generated IDs, captured frames).
-
-3. **subgraph-promote**: Specialized, but necessary for the subgraph feature to work correctly.
-
-### Rationale
-
-- Extensions that don't care can ignore the context.
-- Extensions that do care have the information they need.
-- The 4 values map to 4 distinct operations in the framework.
-- Collapsing contexts would remove functionality with no real simplification gain.
-
-### Mitigation for Complexity
-
-- Document common patterns clearly
-- Most extensions only need: `if (context === 'prompt')`
-- Provide examples in JSDoc
-
-## Note on Deprecation
-
-The `NodeBeforeSerializeEvent` is deprecated (ADR-0010). The `WidgetBeforeSerializeEvent` remains supported and uses the same 4 contexts.
-
-Since node-level serialization is being removed, this research applies to widget-level serialization only.

-# Widget State Categories
-
-Date: 2026-05-12
-
-## Overview
-
-Widget state in the v2 extension API is organized into distinct categories, each with different characteristics for mutability, persistence, and event handling.
-
-## Categories
-
-### 1. Identity (Read-Only Invariants)
-
-Set at construction, never change.
-
-| Property     | Type             | Notes                                |
-| ------------ | ---------------- | ------------------------------------ |
-| `entityId`   | `WidgetEntityId` | Branded, stable for widget lifetime  |
-| `name`       | `string`         | Widget name as registered            |
-| `widgetType` | `string`         | e.g., `'INT'`, `'STRING'`, `'COMBO'` |
-| `label`      | `string`         | Display label, defaults to `name`    |
-
-**Constraints:**
-
-- No setters exist for these properties
-- Extensions cannot modify identity after creation
-- Attempting to change identity is a design error
-
-### 2. Value (First-Class, Every Widget)
-
-The primary user-edited data.
-
-| Method              | Notes                               |
-| ------------------- | ----------------------------------- |
-| `getValue()`        | Returns current value               |
-| `setValue(v)`       | Dispatches `SetWidgetValue` command |
-| `on('valueChange')` | Fires on value mutation             |
-
-**Constraints:**
-
-- Type varies by widget type (`number` for INT, `string` for STRING, etc.)
-- Persisted to `widgets_values` in workflow JSON
-- Included in API prompt by default (unless `setSerializeEnabled(false)`)
-- Changes are undo-able via command dispatch
-
-### 3. Properties (First-Class, Every Widget)
-
-Common properties all widgets share.
-
-| Property    | Getter                 | Setter                   | Event            |
-| ----------- | ---------------------- | ------------------------ | ---------------- |
-| `hidden`    | `isHidden()`           | `setHidden(b)`           | `propertyChange` |
-| `disabled`  | `isDisabled()`         | `setDisabled(b)`         | `propertyChange` |
-| `serialize` | `isSerializeEnabled()` | `setSerializeEnabled(b)` | `propertyChange` |
-
-**Constraints:**
-
-- Boolean values only
-- `hidden` affects UI visibility, not serialization
-- `disabled` makes widget read-only in UI
-- `serialize` controls inclusion in workflow/prompt output
-- Changes fire `propertyChange`, not `valueChange`
-
-### 4. Options Bag (Type-Specific)
-
-Per-instance overrides for type-specific configuration.
-
-| Method                  | Notes                                          |
-| ----------------------- | ---------------------------------------------- |
-| `getOption(key)`        | Returns per-instance override or class default |
-| `setOption(key, value)` | Persists to `widget_options` sidecar           |
-| `on('optionChange')`    | Fires on option mutation                       |
-
-**Common options by widget type:**
-
-| Widget Type | Options                            |
-| ----------- | ---------------------------------- |
-| INT, FLOAT  | `min`, `max`, `step`, `precision`  |
-| STRING      | `multiline`, `placeholder`, `rows` |
-| COMBO       | `values`                           |
-
-**Constraints:**
-
-- Options are JSON-serializable values
-- Persisted separately from `widgets_values` (additive, backward-compatible)
-- Extensions can add custom options
-- Option keys should be documented per widget type
-
-### 5. DOM-Specific
-
-Properties unique to DOM widgets.
-
-| Method          | Notes                                      |
-| --------------- | ------------------------------------------ |
-| `setHeight(px)` | Updates reserved height, triggers relayout |
-
-**Constraints:**
-
-- Only meaningful for `addDOMWidget()` widgets
-- No-op for non-DOM widgets
-- Measured in pixels (screen space)
-- No event fired; relayout is automatic
-
-## Category Interaction Rules
-
-### Event Separation
-
-Each category has its own event:
-
-| Category   | Event            |
-| ---------- | ---------------- |
-| Value      | `valueChange`    |
-| Properties | `propertyChange` |
-| Options    | `optionChange`   |
-
-**Rule**: Events do not cross categories. Changing `hidden` does not fire `valueChange`.
-
-### Serialization Behavior
-
-| Category   | Serialization                                                    |
-| ---------- | ---------------------------------------------------------------- |
-| Identity   | Not serialized (derived from node type)                          |
-| Value      | `widgets_values` array                                           |
-| Properties | `hidden`/`disabled` not persisted; `serialize` affects inclusion |
-| Options    | `widget_options` sidecar object                                  |
-
-### Mutability Summary
-
-| Category   | Mutable | Undo-able | Fires Event      |
-| ---------- | ------- | --------- | ---------------- |
-| Identity   | ✗       | —         | —                |
-| Value      | ✓       | ✓         | `valueChange`    |
-| Properties | ✓       | ✓         | `propertyChange` |
-| Options    | ✓       | ✓         | `optionChange`   |
-| DOM Height | ✓       | ✗         | —                |
-
-## Agent Implementation Notes
-
-Agents working with widget state should:
-
-1. **Respect category boundaries**: Don't try to `setValue()` to change visibility; use `setHidden()`.
-
-2. **Use appropriate events**: Listen to `propertyChange` for UI state, `valueChange` for data.
-
-3. **Handle type-specific options carefully**: Check widget type before accessing type-specific options.
-
-4. **Preserve identity invariants**: Never try to change `entityId`, `name`, `widgetType`, or `label`.
-
-5. **Consider serialization context**: Options persist to a sidecar; values persist to the main array.

-  notes:
-    - Categories cluster by intent, not by surface_family. S2 is split into creation / teardown / hydration / interaction /
-      drawing / connection / serialization / properties.
-    - S1 hooks are merged with their prototype-patching equivalents where intent matches (BC.20 node-type reg, BC.22 menus,
-      BC.03 hydration).
-    - S8.P1 isVirtualNode is a registration-time flag, so it lives in BC.20 alongside the node-type registration hooks.
-    - S10.D3 setSize and S15.OS1 dynamic outputs join S10.D1 in BC.09 dynamic-slot-mutation since they all describe runtime
-      topology mutation.
-    - S14.ID1 NodeLocatorId joins S11.G2 graph enumeration in BC.29 because both are about cross-scope node identity/resolution.
-    - S11.G1/G3/G4 (version, batching, setDirtyCanvas) collapse into BC.30 graph change-tracking — the v2 reactivity story replaces
-      all three.
-    - BC.21 (S1.H2 getCustomWidgets) has only 2 evidence rows in database.yaml; this is the 'small family — 2 + 1 minor variant'
-      acceptance carve-out. The two exemplars are kept as-is, no synthetic third row.
-    - BC.31 and BC.32 added 2026-05-08 from Notion API usage research (notion-api-research-evidence.yaml staging).
-      S16 is a new surface family (DOM injection) not previously tracked. S16.VUE1 grouped with BC.32 (embedded runtimes).
-      S3.C2 (ContextMenu replacement) added to BC.06 member list.
-    - Notion source also upgrades occurrence signal on BC.01/BC.02/BC.04/BC.06/BC.07/BC.09/BC.26/BC.29/BC.30 — reflected
-      in staging file; usage_weight values below are NOT yet updated (need re-run of rollup-blast-radius.py after merge).
-    - BC.33 (cross-ext DOM widget obs), BC.34 (settings dialog), BC.35 (pre-queue validation) added 2026-05-08 from Notion COM-3668.
-    - BC.36 (PrimeVue widget API surface) added 2026-05-08 from Notion Widget Component APIs page; was erroneously numbered BC.33 — corrected.
-    - BC.37 (VueNode bridge timing) added 2026-05-08 from Notion Frontend Architecture page (3536d73d). Captures the
-      nodeCreated→VueNode-not-yet-mounted hazard and the waitForLoad3d deferral pattern as a concrete test fixture.
-categories:
-  - category_id: BC.01
-    name: 'Node lifecycle: creation'
-    intent: Hooks fired when a node is constructed or attached to the graph (per-instance setup).
-    notes: >-
-      nodeCreated fires BEFORE the VueNode Vue component mounts. Extensions that need to access
-      VueNode-backed state (DOM widgets, Three.js renderers, etc.) must defer to onNodeMounted
-      (v2) or waitForLoad3d-style callbacks (v1). See BC.37 for the deferred-mount bridge pattern.

-    intent: Transform a widget's value at workflow-serialization time (dynamic prompts, hidden state, expand-on-save).
-    notes: >-
-      widget.options.serialize===false widgets (e.g. control_after_generate) still occupy a widgets_values
-      slot and still fire serializeValue — excluded only from the backend prompt by graphToPrompt(). Test
-      triple must cover this case explicitly. PR #10392 widgets_values_named is the v2 migration path;
-      WidgetHandle identity must be by name not position. See research/architecture/widget-serialization-historical-analysis.md.

-    notes: >-
-      Root cause: widgets_values is positional — prototype.serialize patchers consume/produce this array

-      widgets, V3 IO.MultiType topology-dependent widget count. NaN→null pipeline produces silent

-      default. PR #11884 guard, PR #10392 named map. See research/architecture/widget-serialization-historical-analysis.md.

-    name: Cross-extension DOM widget creation observation
-    intent:
-      An extension observes when *any* DOM widget is created (by any other extension) so it can attach its own
-      listeners — the mechanism the Autocomplete extension needs to wire its input handler to every text widget.

-    usage_weight: 0.0
-    notes: >-
-      Identified from COM-3668. Distinct from BC.05 (creating DOM widgets) and BC.10 (subscribing to value changes).
-      Gap: no v1 hook fires for cross-extension widget creation observation. v2 shape: onDOMWidgetCreated(handler)
-      in defineExtension setup context. usage_weight pending blast-radius re-run.

-    name: VueNode bridge timing — deferred mount access
-    intent: >-
-      Extensions that register in nodeCreated but need to access Vue-component-backed state
-      (Three.js renderer, DOM widget, ComponentWidgetImpl value) must defer until the Vue
-      component's onMounted fires. The v1 pattern is waitForLoad3d(node, cb); the v2 pattern
-      is onNodeMounted(() => { ... }) inside defineNodeExtension.
-    member_pattern_ids:
-      - S4.W5
-    notes: >-
-      Source: Notion Frontend Architecture page 3536d73d (2026-05-08). nodeCreated gives the
-      LiteGraph node; the VueNode Vue component has NOT mounted yet. waitForLoad3d in
-      src/extensions/core/Load3D is the canonical v1 fixture. ComponentWidgetImpl dual-identity:
-      LiteGraph side (value/callback/name) vs Vue side (props/emits/lifecycle).
-      v2 contract: onNodeMounted() hook fires after Vue component mount — this is the correct
-      timing for accessing VueNode-backed resources.
-      Informs: I-SR.2.B2 (NodeInstanceScope must not sync-access VueNode at setup time),
-      I-TF.3.C1 (harness must simulate two-phase mount), I-TF.2 test triple for BC.37.
-      D8 relevance: app.rootGraph is not reactive (confirmed by this doc) — the exact gap D8 solves.

-      behavior, or read-only state across modes need a stable event — not polling or heuristics
