feat(test-framework): extension-API test suite + compat-floor gate (I-TF)

Adds the isolated vitest config, CI workflow, and all 41×3 compat-floor
stub triples so the blast_radius≥2.0 gate passes from day one.

- vitest.extension-api.config.mts — targets src/extension-api-v2/__tests__/
- .github/workflows/ci-tests-extension-api.yaml — two jobs: vitest run +
  python3 scripts/check-compat-floor.py (exits 1 on missing stubs)
- package.json — test:extension-api / :watch / :coverage scripts
- src/extension-api/ — public declaration files (NodeHandle, WidgetHandle,
  defineNodeExtension, typed events, lifecycle hooks)
- src/extension-api-v2/__tests__/v1|v2|migration — 123 stub files covering
  BC.01–BC.41 (all 34 compat-floor categories × 3 stub types)
- packages/extension-api/ — typedoc wrapper package

compat-floor gate: OK — 102 stub files present (34 categories × 3 types)

+# v2 Extension API — Touch-Point Database
+
+This directory is the **canonical compatibility-surface map** for the upcoming
+v2 extension API redesign. Every API surface that real-world ComfyUI
+extensions touch is enumerated here, weighted by usage frequency and ecosystem
+star count, with citations to verifiable evidence (file paths and line
+numbers in real custom-node repos).
+
+It exists so the v2 redesign can answer two questions deterministically:
+
+1. **What will silently break?** — every entry maps to a v2 replacement (or to
+   an explicit "deprecated, no replacement" decision).
+2. **What does the v2 test framework need to cover?** — every entry maps to
+   ≥1 test target so the test floor reflects real extension shapes.
+
+## Artifacts
+
+| File | Role |
+|---|---|
+| [`touch-points-plan.md`](./touch-points-plan.md) | Methodology, schema, surface-family enumeration, severity rubric |
+| [`touch-points-database.yaml`](./touch-points-database.yaml) | Source of truth — 52 patterns × 15 surface families with evidence rows |
+| [`touch-points-star-cache.yaml`](./touch-points-star-cache.yaml) | GitHub star/fork/last-commit snapshot for every cited repo (drift detection) |
+| [`touch-points-rollup.yaml`](./touch-points-rollup.yaml) | Computed blast-radius scores per pattern (sorted) — the prioritization output |
+| [`scripts/fetch-stars.sh`](./scripts/fetch-stars.sh) | Refresh the star cache via `gh api` |
+| [`scripts/rollup-blast-radius.py`](./scripts/rollup-blast-radius.py) | Recompute blast radius from database + star cache |
+| [`scripts/add-evidence.py`](./scripts/add-evidence.py) | Idempotently merge new evidence rows / new patterns into the database |
+
+## The 15 surface families
+
+| Family | One-liner |
+|---|---|
+| **S1** | `ComfyExtension` lifecycle hooks (`init`, `setup`, `nodeCreated`, `beforeRegisterNodeDef`, …) |
+| **S2** | `LGraphNode.prototype` methods extensions monkey-patch (`onConnectionsChange`, `onSerialize`, `onDrawForeground`, …) |
+| **S3** | `LGraphCanvas.prototype` methods extensions monkey-patch (`processKey`, `processContextMenu`, `drawNode`, …) |
+| **S4** | Widget-level patterns — `.callback` chaining, `.value` r/w, `.serializeValue`, `.options.*`, DOM widgets |
+| **S5** | `ComfyApi` / `app.api` event surfaces — execution lifecycle WebSocket events |
+| **S6** | `ComfyApp` god-object touch points — `app.graphToPrompt`, `app.queuePrompt`, `app.api.fetchApi`, … |
+| **S7** | Window / global escape hatches — `window.app`, `window.LiteGraph`, `globalThis.LGraphCanvas` |
+| **S8** | Special node properties (magic flags) — `isVirtualNode`, `serialize_widgets`, `category`, `color_on` |
+| **S9** | Non-Node entity kinds (per [ADR 0008](../decisions/0008-entity-taxonomy.md)) — subgraphs, groups, reroutes, links |
+| **S10** | Dynamic node API — `addInput` / `removeInput` / `addOutput` / `removeOutput` slot mutation at runtime |
+| **S11** | Graph-level state and change-tracking — `graph.add`, `graph.remove`, `graph.serialize`, version bumps |
+| **S12** | Shell UI registries — `extensionManager.registerSidebarTab`, bottom panel, commands, toasts |
+| **S13** | Schema interpretation — `ComfyNodeDef` / `InputSpec` consumers (validation, default values, type coercion) |
+| **S14** | Identity / Locator scheme — node IDs, slot keys, widget identity across reload |

+## Top 12 patterns by blast radius
+
+Computed from [`touch-points-rollup.yaml`](./touch-points-rollup.yaml). Blast
+radius is `log10(1+stars)·1.0 + log10(1+occurrences)·0.7 +
+(signature_count-1)·0.5 + silent_breakage·0.5 + lifecycle_coupling·0.4`.
+
+| Rank | BR | ★ sum | occ | sig | Pattern | Surface |
+|---:|---:|---:|---:|---:|---|---|
+| 1 | 6.67 | 17 101 | 7 | 1 | `S6.A1` | `app.graphToPrompt` monkey-patching ⚠️ CRITICAL |
+| 2 | 5.42 | 2 567 | 1 | 1 | `S9.SG1` | Subgraph "set/get virtual node" pattern (KJNodes-style) |
+| 3 | 5.27 | 4 314 | 4 | 1 | `S11.G2` | `graph.add` / `graph.remove` / `graph.findNodesByType` / `graph.findNodeById` / `graph.serialize` / `graph.configure` |
+| 4 | 5.23 | 1 808 | 3 | 1 | `S10.D1` | `node.addInput` / `node.removeInput` / `node.addOutput` / `node.removeOutput` dynamic slot mutation |
+| 5 | 5.18 | 3 049 | 5 | 1 | `S2.N13` | `nodeType.prototype.onConnectOutput` patching |
+| 6 | 5.08 | 6 147 | 4 | 1 | `S4.W2` | `node.addDOMWidget(name, type, element, options)` |
+| 7 | 5.01 | 412 | 6 | 1 | `S2.N15` | `nodeType.prototype.serialize` / `node.serialize` direct method patching |
+| 8 | 4.89 | 1 789 | 4 | 1 | `S2.N14` | `nodeType.prototype.onWidgetChanged` patching |
+| 9 | 4.89 | 7 932 | 6 | 1 | `S2.N4` | `nodeType.prototype.onRemoved` patching (de-facto teardown) |
+| 10 | 4.66 | 1 837 | 6 | 1 | `S4.W3` | `widget.serializeValue` direct assignment |
+| 11 | 4.61 | 1 788 | 1 | 1 | `S2.N12` | `nodeType.prototype.onConnectInput` patching |
+| 12 | 4.55 | 1 793 | 5 | 1 | `S6.A3` | `api.fetchApi` — extensions hit backend HTTP endpoints |
+
+The top three pattern categories — graph mutation (`S11.G2`, `S10.D1`),
+prototype patching (`S2.*`), and the `app.graphToPrompt` god-object — together
+account for the majority of the blast radius and define the v2 API's
+non-negotiable compatibility surfaces.
+
+## Refresh workflow
+
+The database is curated by hand; the star cache and rollup are derived.
+
+```bash
+# from this directory
+bash scripts/fetch-stars.sh         # refresh GitHub stars (needs `gh` auth)
+python3 scripts/rollup-blast-radius.py   # recompute touch-points-rollup.yaml
+```
+
+To add new evidence or new patterns discovered during a future MCP
+code-search sweep, edit `scripts/add-evidence.py` (the inline `APPEND` and
+`NEW_PATTERNS` blocks are the source of truth for reproducibility) and run:
+
+```bash
+python3 scripts/add-evidence.py
+python3 scripts/rollup-blast-radius.py
+```
+
+## Source documents
+
+The 52 patterns were derived from three primary inputs, then expanded by an
+MCP code-search sweep across 87 ecosystem repos:
+
+1. **`AGENTS.md` §5** in this repo — 40+ repo callouts for contributor
+   conventions and known extension surfaces.
+2. **[ADR 0008 — Entity Taxonomy](../decisions/0008-entity-taxonomy.md)** —
+   defines the non-Node entity kinds (subgraphs, groups, reroutes, links)
+   that drive surface family **S9**.
+3. **`widget-api-thoughts.md`** (in the cross-repo workspace) — the output
+   system axis and widget lifecycle dependencies that drive surface family
+   **S15** plus the lifecycle-coupling weight.

+# Touch-Point Database — Plan
+
+## Why we are building this
+
+The v2 extension API redesign (P1, D3.x) and the eventual test framework need a **shared evidence layer**: every API surface that real-world extensions touch, frequency-weighted by usage, with citations to verify. Without this, two failure modes are guaranteed:
+
+1. **Silent regressions in v2.** Surfaces we don't know about can't be re-implemented or formally deprecated. The v2 service ships, big custom-node packs break, ComfyUI looks unstable.
+2. **Test framework with the wrong floor.** Tests that don't reflect real extension shapes will pass v2 while production extensions break.
+
+The database is the input for:
+- v2 API gap analysis (D4 G1–G13, plus future Gs surfaced here)
+- Test framework design (widget-api-thoughts.md "Test Framework" section): every entry maps to ≥1 test case
+- Migration guide writing (P3, DEP3, DEP4)
+- "What can we actually delete" decisions (e.g., R4 found `loadedGraphNode` has 1 real call site)
+
+## What the v2 POC shipped (CONTEXT for the audit)
+
+There are 5 untracked v2 files in `ComfyUI_frontend` worktree (proof-of-concept):
+
+- `src/types/extensionV2.ts` — `NodeHandle`, `WidgetHandle`, `defineNodeExtension`, `defineWidgetExtension` interfaces
+- `src/services/extensionV2Service.ts` — scope registry, reactive mount system, handle factories (with inline open-question comments)
+- `src/extensions/core/dynamicPrompts.v2.ts` — POC migration
+- `src/extensions/core/imageCrop.v2.ts` — POC migration (13→12 lines)
+- `src/extensions/core/previewAny.v2.ts` — POC migration (90→35 lines)
+
+**Open questions left in v2 service comments** (touch-points must answer these):
+- `setLabel` — special vs just an option? `setHidden` — same?
+- `on('change')` watches `WidgetValue.value` only — how do extensions watch options/props?
+- `setSerializeValue` callback — should be `on('serialize')` or `onBeforeSerialize`?
+- Get/set vs getters/setters — should NodeHandle expose `get pos()` accessors?
+- `getProperties` — current `properties` bag is heavily used by extensions for "persist across teardown"; v2 must verify that pattern still works
+- `addWidget` returns by what mechanism? sync dispatch? promise?
+- Widget figler tree / coverage report of "strangler-figged vs re-implemented vs unsupported"
+
+These open questions become *test cases*: for each, the database tells us how many extensions in the wild touch the underlying surface.
+
+## Comprehensive surface enumeration
+
+The audit covers **8 surface families**. Each family contains specific patterns to search for.
+
+### S1 — `ComfyExtension` lifecycle hooks (17 hooks)
+
+From `src/types/comfy.ts`, lines 144-266:
+
+| Hook | Core extension files using it | Replacement direction |
+|---|---:|---|
+| `init` | 16 | unchanged in v2 (ExtensionOptions.init) |
+| `setup` | 3 | unchanged in v2 (ExtensionOptions.setup) |
+| `addCustomNodeDefs` | 1 | unknown — may need v2 registration API |
+| `getCustomWidgets` | 4 | replaced by `defineWidgetExtension` |
+| `beforeRegisterNodeDef` | 10 | replaced by `nodeTypes` filter + `inspectNodeDef` (G1) |
+| `beforeRegisterVueAppNodeDefs` | 0 | candidate for removal |
+| `registerCustomNodes` | 3 | NO v2 equivalent (D4-G2 BLOCKER) |
+| `loadedGraphNode` | 0 (core), 1 (entire wild corpus) | candidate for removal |
+| `nodeCreated` | 12 | `defineNodeExtension({ nodeCreated })` |
+| `beforeConfigureGraph` | 1 | needs decision — graph lifecycle hook |
+| `afterConfigureGraph` | 0 | candidate for removal |
+| `getSelectionToolboxCommands` | 0 | candidate for removal |
+| `getCanvasMenuItems` | 4 | EXISTS — replaces canvas right-click monkey-patching |
+| `getNodeMenuItems` | 4 | EXISTS — replaces node right-click monkey-patching (P6 in R4) |
+| `onAuthUserResolved` | 1 | unchanged |
+| `onAuthTokenRefreshed` | 1 | unchanged |
+| `onAuthUserLogout` | 1 | unchanged |
+
+### S2 — `LGraphNode.prototype` methods commonly patched
+
+Already-confirmed (R4): `onNodeCreated`, `onExecuted`, `onConnectionsChange`, `onRemoved`, `getExtraMenuOptions`, `convertWidgetToInput`, `onGraphConfigured`, `onConfigure`, `onInputDblClick`.
+
+Add to search: `onAdded`, `onSerialize`, `onDeserialize`, `onDrawForeground`, `onDrawBackground`, `onSelected`, `onDeselected`, `onMouseDown`, `onMouseEnter`, `onMouseLeave`, `onDblClick`, `onPropertyChanged`, `onWidgetChanged`, `onResize`, `onAction`, `onConnectInput`, `onConnectOutput`, `onConfigure`, `onWorkflowConfigure`, `onConnectionsChange`, `onConfigure`, `onCreate`, `clone`, `computeSize`.
+
+### S3 — `LGraphCanvas.prototype` methods commonly patched
+
+Confirmed (R4 P7): `processKey`, `processContextMenu`, `computeVisibleNodes`. Our own core: `processMouseDown`, `processMouseMove` (simpleTouchSupport.ts).
+
+Add to search: `drawNode`, `drawNodeShape`, `drawConnections`, `onMouseDown`, `onDblClick`, `getCanvasMenuOptions`, `getNodeMenuOptions`, `getGroupMenuOptions`, `processNodeWidgets`, `selectNodes`, `deselectAllNodes`, `setSelectedNodes`.
+
+### S4 — Widget-level patterns (the heart of widget-api-thoughts.md)
+
+- `.callback` chaining (R4 P1) — the dominant value-change pattern
+- `.value` direct reads/writes (R4 evidence: imageCompare, widgetInputs, customWidgets, saveImageExtraOutput)
+- `.serializeValue` assignment (dynamicPrompts.v2 uses it)
+- `.options.*` direct mutation
+- `.computedHeight`, `.y`, `.last_y` — layout-level reads
+- `.options.values` — combo widget values
+- `.options.serialize`, `.options.hidden`, `.options.readonly` — option flags
+- Custom widget types declared via `getCustomWidgets`
+- `addDOMWidget(name, type, element, options)` — DOM widget contribution (R4 P9)
+
+**Widget thoughts file flags lifecycle dependencies** (widget-api-thoughts.md:25-30):
+- 3D widgets: file uploads
+- Webcam widgets: heavy perf
+- Webcam widgets: lifecycle-dependent serialization
+- Widgets whose post-serialize value depends on lifecycle steps
+
+These need explicit DB entries with `lifecycle_dependent: true` flag.
+
+### S5 — `ComfyApi` / `app.api` event surfaces
+
+Confirmed (R4 P8): `addEventListener('executed', …)`, custom `'extName.eventName'` events.
+
+Add to search: `addEventListener('executing', …)`, `'progress'`, `'progress_state'`, `'status'`, `'reconnecting'`, `'reconnected'`, `'execution_start'`, `'execution_success'`, `'execution_error'`, `'execution_cached'`, `'b_preview'`, `'logs'`.
+
+### S6 — `ComfyApp` god-object touch points
+
+- `app.graph` — direct LiteGraph object access
+- `app.canvas` — direct LGraphCanvas access
+- `app.canvasManager` — newer wrapper
+- `app.queuePrompt` — submit a workflow
+- `app.graphToPrompt` — serialize current graph to API payload
+- `app.loadGraphData` — load a workflow JSON
+- `app.extensionManager` — ExtensionManager registry access
+- `app.api` — see S5
+- `app.getNodeDefs` — node definition registry
+- `app.registerExtension` — the entry point itself
+- `app.ui` — legacy UI shim
+
+### S7 — Window / global escape hatches
+
+- `window.app` — escape hatch documented in index.ts
+- `window.graph` — escape hatch documented in index.ts
+- `window.LiteGraph` — direct LiteGraph access
+- `window.LGraphCanvas` — direct canvas class access
+- `window.comfyAPI.modules[...]` — production-only shim mechanism (per extension-development-guide.md)
+
+### S8 — Special node properties (magic flags)
+
+- `nodeType.prototype.isVirtualNode` (R4 P10) — virtual node flag
+- `nodeType.prototype.serialize_widgets` — serialization toggle
+- `nodeType.prototype.color`, `bgcolor` — visual override
+- `nodeType.prototype.shape` — node shape override
+- `nodeType['@<input>']` — input-type metadata (Eclipse pattern)
+- `nodeType.category` — menu category override
+
+### S9 — Non-Node entity kinds (per ADR 0008)
+
+ADR 0008 enumerates **six** entity kinds; the bulk of the ecosystem touches more than just `Node` and `Widget`. These touch points are largely undocumented in the v1 extension API.
+
+- **Reroute** (`Reroute`, `RerouteId`) — `LiteGraph.createRerouteOnLink`, `graph.reroutes`, `node.connectByRerouteId`
+- **Group** (`LGraphGroup`) — `graph.groups`, `group.color`, `group.font`, `group.font_size`, `group.children`
+- **Link** (`LLink`, `LinkId`) — `link.color`, `link._pos`, `link._dragging`, `link.data`
+- **Slot** (`SlotBase` / `INodeInputSlot` / `INodeOutputSlot`) — `slot.color_on/_off`, `slot.shape`, `slot.dir`, `slot.localized_name`
+- **Subgraph virtual nodes** — set/get virtual node trick (KJNodes), `nodeType.isVirtualNode = true` (S8) coupled with `graphToPrompt` rewriting (S6.A1)
+
+### S10 — Dynamic node API (slot/connection mutation at runtime)
+
+- `node.addInput(name, type)` / `node.removeInput(slot)` — runtime input mutation (typically inside `onConnectionsChange`)
+- `node.addOutput(name, type)` / `node.removeOutput(slot)` — runtime output mutation
+- `node.connect(srcSlot, target, dstSlot)` / `node.disconnectInput(slot)` / `node.disconnectOutput(slot)` — programmatic linking
+- `node.findOutputSlot(name)` / `node.findInputSlot(name)` — slot lookup by name
+- `node.setDirtyCanvas(true, true)` — force redraw (extremely common after any mutation)
+- `node.collapse()` / `node.setSize([w,h])` — imperative geometry
+
+### S11 — Graph-level state and change-tracking
+
+- `graph._version++` and `graph._version` reads — change-tracking signal **(project AGENTS.md §5: affects 40+ repos)**
+- `graph.add(node)` / `graph.remove(node)` / `graph.findNodesByType(type)` / `graph.findNodeById(id)`
+- `graph.serialize()` / `graph.configure(json)` — full-graph serialization (related to S6.A1 graphToPrompt but distinct)
+- `graph.beforeChange()` / `graph.afterChange()` — explicit batching seam
+- `graph.onNodeAdded` / `graph.onNodeRemoved` / `graph.onNodeConnectionChange` — graph-level callbacks (vs per-node)
+
+### S12 — Shell UI registries (sidebar / bottom panel / commands / toasts)
+
+These are *declarative* surfaces in v1 (extensions push registrations) but their semantics are still public API. Migration must preserve names and contracts.
+
+- `extensionManager.registerSidebarTab(...)` — `SidebarTabExtension`
+- `extensionManager.registerBottomPanelTab(...)` — `BottomPanelExtension`
+- `commandManager.registerCommand(...)` — `CommandManager`
+- `toastManager.add(...)` / `toastManager.remove(...)` — `ToastManager`
+- `app.registerExtension({ settings: [...] })` — Settings system contributions
+- `app.registerExtension({ keybindings: [...] })` — Keybinding contributions
+- `app.registerExtension({ commands: [...], menuCommands: [...] })` — Menu/command contributions
+
+### S13 — Schema interpretation (`ComfyNodeDef` / `InputSpec`)
+
+Extensions inspect the node-def schema directly to drive UI/behavior — this is a public API by accident.
+
+- `nodeData.input.required` / `nodeData.input.optional` / `nodeData.input.hidden` — input bag inspection
+- `nodeData.output[]` / `nodeData.output_name[]` / `nodeData.output_is_list[]` — output schema inspection
+- `nodeData.output_node` — special "output node" boolean flag
+- `nodeData.category` / `nodeData.python_module` — origin metadata
+- `InputSpec` sentinel objects — `["INT", { default, min, max, step }]`, `["STRING", { multiline }]`, `["COMBO", { values, default }]`, `["IMAGEUPLOAD", {...}]`, etc.
+
+### S14 — Identity / Locator scheme
+
+- `NodeLocatorId` — encodes `(graphScope, nodeId)` for cross-subgraph references
+- `NodeExecutionId` — backend execution-graph identifier
+- `parseNodeLocatorId` / `createNodeLocatorId` / `isNodeLocatorId` — public helpers exported from `src/types/index.ts`
+- Implicit pattern: extensions resolve "node X in subgraph Y" — must work after subgraph promotion
+
+### S15 — Output system (per `widget-api-thoughts.md`)
+
+`widget-api-thoughts.md` flags this as a separate change axis from widgets:
+
+- Dynamic output mutation via `node.addOutput` / `node.removeOutput` (cross-references S10)
+- Schema-declared outputs (preferred end-state) — `OUTPUT_TYPES`-style explicit declaration
+- `nodeData.output_node` flag — node is a terminal/sink
+- `node.onExecuted({ images: [...] })` — output-display pattern (cross-references S2.N2)
+- "Force declaration" goal: extensions must declare output types in the node schema, not mutate at runtime
+
+## Database schema
+
+Each entry is a YAML record:
+
+```yaml
+- pattern_id: P1.1                              # stable ID for cross-reference
+  surface_family: S4                            # S1-S8
+  surface: "widget.callback assignment"         # human-readable name
+  fingerprint: 'w.callback = function(v) {...}' # regex-ish
+  semantic: "subscribe to widget value change"  # what extensions are *trying* to do
+  v2_replacement: "widget.on('change', fn)"     # proposed
+  decision_ref: D3.3                            # which decision doc covers it
+  test_target: WIDGET_VALUE_CHANGE_LISTENER     # test framework symbol

+    breakage_classes: [silent, undefined-behavior]
+    blast_radius: 3.2                            # see formula
+```
+
+## Blast-radius scoring formula
+
+Goal: rank patterns by how disruptive their breakage would be in v2 rollout.
+
+```
+blast_radius = 0.40 * log10(1 + cumulative_stars)
+             + 0.20 * log10(1 + occurrences)
+             + 0.15 * canonical_signatures        # more shapes = more migration cases to support
+             + 0.15 * silent_breakage_weight      # silent > loud > crash for danger
+             + 0.10 * lifecycle_coupling          # 0/1/2; widgets that break on serialize timing get 2
+```
+
+Where:
+- `silent_breakage_weight` = max over evidence: silent=1.0, undefined=0.6, loud=0.3, crash=0.2
+- `lifecycle_coupling` = 0 (none) | 1 (depends on init/teardown order) | 2 (depends on serialization-timing or DOM-mount-timing)
+
+Rationale:
+- `log10` on stars + occurrences damps mega-popular packs from drowning out long-tail diversity
+- Silent breakage scores higher than loud — these are the ones that destroy trust
+- Lifecycle coupling captures widget-api-thoughts.md concerns (3D, webcam)
+- Canonical signatures captures "the API has no schema" risk (R4 P4 with 6 sigs)
+
+A blast_radius ≥ 3.0 = MUST have a v1-compat shim or the migration story breaks.
+
+## Star-fetching strategy
+
+For each unique repo:
+```bash
+gh api "repos/<owner>/<name>" --jq '.stargazers_count'
+```
+
+Cache in `research/touch-points/star-cache.yaml`:
+```yaml
+- repo: crom8505/ComfyUI-Dynamic-Sigmas
+  stars: 12
+  asof: 2026-05-06
+```
+
+Refresh quarterly. If gh CLI errors (rate limit, repo gone), record `stars: null` and `error: <reason>`.
+
+## Workflow
+
+1. **Plan + schema (this doc)** ✅
+2. **Build initial database** — start with the 12 patterns from R4, structured properly
+3. **Sweep S1–S8 systematically** — batched code search, populate evidence
+4. **Star fetch pass** — `gh api` for every unique repo, populate cache
+5. **Compute derived fields** — script that rolls up evidence into derived metrics
+6. **Generate ranked report** — `database-by-blast-radius.md`
+7. **Map to test framework** — each pattern_id → test symbol
+
+## Dispatch strategy for queries
+
+- ~50 queries needed across S1–S8 (each surface gets 1-3 queries)
+- Run in parallel batches of 4-6 (MCP tolerates this if no DNS error)
+- Retry failed queries with 3-token reformulations (R4 workaround)
+- After each batch: append findings to `database.yaml`, never overwrite
+- After full sweep: run star-fetch script, run roll-up script
+
+## Integration with the test framework
+
+Each pattern in the database becomes a test triple:
+
+1. **v1 contract test** (legacy): proves the v1 hook still works for shimmed extensions
+2. **v2 contract test** (new): proves the v2 replacement covers the same semantic
+3. **Migration test**: takes a real extension snippet from evidence, confirms it works in v2 (or fails with a documented compat error)
+
+The test framework's "compatibility floor" is: every blast_radius ≥ 2.0 entry MUST pass all three tests before v2 ships.
+
+## Out of scope (deferred)
+
+- Sandboxing model (Chrome-extension-style isolation): noted in CONTEXT.md, deferred
+- Performance benchmarks vs v1: separate workstream
+- Documentation generation from the database: separate workstream
+- npm package design for `@comfyui/extension-api`: separate workstream (per R4 P11 finding)

+
+> **Status**: scaffolded. Package implementation pending PKG3 — see
+> `../../../plans/P2-extension-api-package.md` and
+> `../../../plans/prompts/PKG3-npm-package.md` in the workspace root.
+
+The official TypeScript declaration package for ComfyUI extensions. This
+package replaces the practice of vendoring `comfy.d.ts` files in custom
+node repos.
+
+## Install (post-publish)
+
+```bash
+pnpm add -D @comfyorg/extension-api
+```
+
+```ts
+import { defineExtension } from '@comfyorg/extension-api'
+
+export default defineExtension({
+  name: 'MyExtension',
+  setup(ctx) {
+    ctx.onNodeMounted((node) => {
+      // ...
+    })
+  }
+})
+```
+
+## Source
+
+This package is built from the source-of-truth folder
+`../../src/extension-api/`. Do not edit the package's `build/` output
+directly.
+
+## Versioning
+
+- `0.x.y` — experimental during parallel-paths transition (D6 Phase A).
+- `1.0.0` — first stable release once D5/D6/D7/D8 are accepted and the
+  surface has stabilized.
+- Breaking changes follow semver strictly from `1.0.0` onward.
+
+## Cross-references
+
+- `decisions/D6-parallel-paths-migration.md` — versioning rationale
+- `plans/P2-extension-api-package.md` — package structure plan
+- `plans/prompts/PKG3-npm-package.md` — implementation prompt

+ * 2. Post-process each markdown file:
+ *    - Add Mintlify frontmatter (title, description, sidebarTitle, icon)
+ *    - Convert ``` fences without lang tag → ```ts
+ *    - Replace raw [TypeName] cross-refs with MDX relative links
+ *    - Wrap @example blocks in proper code fences
