fix(ext): stub dynamicPrompts.v2 pending defineWidgetAugmenter

Per D-no-node-widget-access (2026-05-19, bilateral A1 closure), nodes
can no longer enumerate widgets — `node.getWidgets()` was removed
from NodeHandle. The previous dynamicPrompts.v2 implementation
iterated node widgets to attach per-widget `beforeSerialize`
handlers; that pattern is now forbidden.

Stubbed pending a follow-up public API (`defineWidgetAugmenter` or
per-widget `setup` on `defineWidget`) that lets extensions attach
behavior to existing widget types matching a predicate. v1
(`Comfy.DynamicPrompts`) continues to work — this is a v2 surface
gap only, not a user-visible regression.

+# 9. Subgraph promoted widgets use linked inputs
+
+Date: 2026-05-05

+
+- [Before/after flow diagrams](./0009-subgraph-promoted-widgets-use-linked-inputs/before-after-flows.md)

+
+## Status
+
+Proposed
+
+## Context
+
+Subgraph widget promotion historically had two overlapping representations:
+
+1. `properties.proxyWidgets`, a serialized list of source node/widget tuples;
+2. linked subgraph inputs, where an interior widget-bearing input is exposed
+   through the subgraph boundary.
+
+This created ambiguous ownership. Runtime value reads could collapse to an
+interior source widget, while host `widgets_values` could also carry an
+exterior value. Multiple host instances of the same subgraph could therefore
+stomp one another, and serialization could mutate interior widgets as a
+persistence carrier for exterior values.
+
+The ECS widget migration makes that ambiguity more expensive: widgets are
+becoming entities with component state keyed by stable entity identity, and
+subgraphs are modeled as graph boundary structure rather than a separate
+promotion-specific entity kind.
+
+## Decision
+
+Promoted widgets are represented only as standard linked `SubgraphInput`
+widgets. A promoted widget is a host-scoped widget entity owned by a subgraph
+input on a host `SubgraphNode`. The interior source widget supplies schema,
+type, options, tooltip, and default metadata, but it is not the owner of the
+host value.
+
+Display-only preview surfacing, such as `$$canvas-image-preview`, is not a
+promoted widget. It is a separate preview-exposure system because it has no
+host-owned widget value, does not feed prompt serialization, and often points at
+virtual `serialize: false` pseudo-widgets that may not exist on the source node.
+
+`properties.proxyWidgets` becomes a legacy load-time input only. Successful
+repair consumes entries from `proxyWidgets`; canonical saves do not re-emit
+those entries. The standard serialized representation is the existing subgraph
+interface/input form plus host-node `widgets_values`.
+
+Display-only preview exposures use their own host-node-scoped serialized entry,
+`properties.previewExposures`, instead of `properties.proxyWidgets` and instead
+of linked `SubgraphInput` widgets. Canonical preview-exposure JSON uses preview
+language, not widget language:
+
+```ts
+type PreviewExposure = {
+  name: string
+  sourceNodeId: string
+  sourcePreviewName: string
+}
+```
+
+Host-node scope preserves current behavior where different instances of the
+same subgraph can choose different exposed previews.
+
+The entry intentionally stores only host preview identity and source locator
+identity. `name` is the host-scoped stable identity for this preview exposure,
+analogous to `SubgraphInput.name`; it is not a display label. It is generated
+with existing collision behavior, such as `nextUniqueName(...)`, when an
+exposure is created. Media type, display labels, titles, image/video/audio URLs,
+and other runtime preview details are derived from the current graph and output
+state. Array order is the canonical display order. Preview exposures do not get
+a separate persisted `label` in this slice; if a future rename UX needs one, it
+should follow the same rule as subgraph inputs: `name` is identity and `label`
+is display-only.
+
+Preview exposures are persisted user choices after creation. Packing nodes into
+a subgraph may auto-add recommended preview exposures for supported output
+nodes, and users may explicitly add or remove additional preview exposures
+afterward. Normal load/save does not re-derive previews from node type alone,
+because that would make old workflows change when support for new preview node
+types is added. Unresolved preview exposures remain persisted and inert;
+automatic cleanup does not prune them. They are removed only by explicit user
+action or by destruction/unpacking of the owning host.
+
+Preview exposures compose through nested subgraph hosts by chaining immediate
+boundaries. If an outer subgraph wants to show a preview exposed by an inner
+subgraph host, the outer `previewExposures` entry points at the immediate inner
+`SubgraphNode`, and `sourcePreviewName` names the inner host's preview-exposure
+identity, not the deepest interior preview name. Runtime preview resolution may
+then follow the inner host's own preview exposures to find media. Canonical JSON
+does not persist flattened deep paths, because deep paths would couple host UI
+state to private nested graph internals.
+
+## Identity and value ownership
+
+- UI/value identity is host-scoped: host node locator plus
+  `SubgraphInput.name`.
+- Host-scoped identity means the host `SubgraphNode` instance within its
+  containing `graphScope`; the interior source node is not the state or
+  persistence owner.
+- `SubgraphInput.name` is the stable internal identity.
+- `SubgraphInput.label` / `localized_name` are display-only.
+- `SubgraphInput.id` may be used for slot-instance reconciliation, not as the
+  persisted widget value key.
+- Source node/widget identity remains metadata for diagnostics, missing-model
+  lookup, schema projection, and migration only.
+- The host/exterior value wins over the interior/source value during repair,
+  persistence, and prompt serialization.
+
+This follows the existing widget/slot convention: `name` is identity, `label`
+is display.
+
+Promoted-widget value state is a host-scoped sparse overlay over source-widget
+metadata and defaults. The source widget remains the schema/default provider;
+host value state is materialized only when the exterior value differs from the
+effective source default or when restored from persisted host state. Canonical
+save/load must not eagerly mirror source defaults or use interior widgets as
+persistence carriers.
+
+## Forward migration
+
+Loading a workflow with legacy `proxyWidgets` runs a one-way repair:
+
+1. Parse `properties.proxyWidgets` with the existing Zod-inferred tuple type.
+2. Invalid raw `proxyWidgets` data logs `console.error`, does not throw, and is
+   not quarantined.
+3. Build a multi-pass association map before mutation:
+   - normalized legacy proxy entry;
+   - projected legacy promoted-widget order;
+   - host `widgets_values` value, preserving sparse holes;
+   - repair strategy or failure reason;
+   - whether the entry is a value widget or display-only preview exposure.
+4. Defer mutations until node IDs/entity IDs are stable and the subgraph graph
+   is configured.
+5. On flush, re-resolve against current graph state, because clone/paste/load
+   flows may have remapped or created nodes and links.
+6. If already represented by a linked `SubgraphInput`, consider the legacy
+   entry resolved and consume it.
+7. Otherwise repair through existing subgraph input/link systems.
+8. If the entry is display-only preview surfacing, migrate it into the separate
+   preview-exposure representation instead of creating a linked `SubgraphInput`.
+9. If value-widget repair fails, write inert quarantine metadata and warn.
+
+The repair is idempotent. Pending plans store tuple/value data and re-check the
+current graph before applying mutations.
+
+Legacy entries are classified as preview exposures when either:
+
+- the legacy source name starts with `$$`; or
+- the source node resolves to a matching pseudo-preview widget, such as a
+  `serialize: false` preview/video/audio UI widget.
+
+Everything else is treated as a value-widget promotion candidate. An unresolved
+preview-shaped entry remains inert at runtime and is still persisted, because
+preview-capable pseudo-widgets and output media can be removed and re-added
+dynamically. It is not quarantined because it has no user value to preserve. A
+non-`$$` entry that cannot resolve to a source widget is a value-widget repair
+failure and follows the quarantine path unless it can resolve to a
+pseudo-preview widget.
+
+## Proxy widget error quarantine
+
+Valid legacy entries that cannot be repaired are persisted in
+`properties.proxyWidgetErrorQuarantine`. Quarantined entries are inert: they do
+not hydrate runtime promoted widgets, do not participate in execution, and are
+not used for app-mode/favorites identity.
+
+Quarantine entries preserve enough information to avoid data loss and support
+future tooling:
+
+```ts
+type ProxyWidgetErrorQuarantineEntry = {
+  originalEntry: ProxyWidgetTuple
+  reason:
+    | 'missingSourceNode'
+    | 'missingSourceWidget'
+    | 'missingSubgraphInput'
+    | 'ambiguousSubgraphInput'
+    | 'unlinkedSourceWidget'
+    | 'primitiveBypassFailed'
+  hostValue?: TWidgetValue
+  attemptedAtVersion: 1
+}
+```
+
+Unresolved legacy UI selections/favorites are dropped with `console.warn`.
+Workflow-level promotion/value intent is preserved by
+`proxyWidgetErrorQuarantine`, not by a second UI quarantine format.
+
+## Primitive-node repair
+
+Legacy `proxyWidgets` may point at `PrimitiveNode` outputs. Primitive nodes
+serve nearly the same purpose as subgraph inputs: they provide a widget value to
+one or more target widget inputs. The migration repairs this expected legacy
+shape in the first migration rather than quarantining it by default.
+
+Primitive repair:
+
+- coalesces exact duplicate legacy entries during planning;
+- uses the primitive node's user title as the base input name when the node was
+  renamed, otherwise the primitive output widget name;
+- applies existing naming behavior and `nextUniqueName(...)` for collisions;
+- uses the existing primitive merge/config compatibility logic;
+- creates one `SubgraphInput` for the primitive fanout;
+- reconnects every former primitive output target to that input in target
+  order, using standard connect/disconnect APIs;
+- applies the host value when one exists, otherwise seeds from the source
+  primitive value;
+- leaves the primitive node and its widget value in place, but disconnected and
+  inert.
+
+Primitive repair is all-or-quarantine. If any target cannot be validated or
+reconnected, the migration does not leave a partial rewrite; it quarantines the
+entry with `hostValue` and logs the reason.
+
+## Serialization
+
+After repair/quarantine:
+
+- `properties.proxyWidgets` is omitted for repaired entries;
+- display-only preview entries are omitted from `properties.proxyWidgets` and
+  emitted through `properties.previewExposures`;
+- `properties.proxyWidgetErrorQuarantine` carries unrepaired valid entries;
+- preview exposures do not carry quarantine values because they do not own user
+  values; unresolved preview exposures remain inert in `previewExposures`;
+- host `widgets_values` contains host-owned values only for canonical host
+  widgets, not source-owned defaults or interior persistence copies;
+- quarantined legacy values live in `proxyWidgetErrorQuarantine.hostValue`;
+- array-form `widgets_values` remains for now.
+
+Preview exposures are display-only UI metadata. They drive host canvas/app-mode
+preview rendering, but they do not create prompt inputs, do not create
+`widgets_values`, do not alter node execution order, do not become executable
+graph edges, and do not participate in prompt serialization. Runtime mapping
+from backend `display_node`/output messages to a host preview exposure is a UI
+projection only.
+
+The old `SubgraphNode.serialize()` behavior that copied exterior promoted
+values into connected interior widgets is removed. A temporary TODO should mark
+that removal point until the migration is proven stable. Host values are
+serialized through standard subgraph-input widgets instead.
+
+Longer term, `widgets_values` should move from array order to an object/map
+keyed by stable widget name, but that migration is out of scope for this
+decision.
+
+## App mode, builder, and favorites
+
+The runtime migration and UI identity migration ship in the same slice. The UI
+must not persist promoted selections by source node/widget identity after this
+change.
+
+Canonical UI identity is:
+
+```ts
+type PromotedWidgetUiIdentity = {
+  hostNodeLocator: string
+  subgraphInputName: string
+}
+```
+
+Legacy source-identity selections are migrated when they resolve through the
+standard input created or confirmed by the migration. Unresolved selections are
+dropped with a warning.
+
+Preview exposure output selections are also host-scoped and must not persist
+interior source node identity. Canonical preview/output identity is:
+
+```ts
+type PreviewExposureUiIdentity = {
+  hostNodeLocator: string
+  previewName: string
+}
+```
+
+The UI references the explicit preview exposure itself. This keeps subgraphs
+opaque: consumers select the host boundary contract, not the interior node that
+currently supplies media. Legacy output selections that refer to interior
+preview source nodes may migrate if they resolve to a preview-exposure chain;
+otherwise they are dropped with `console.warn`. There is no separate preview UI
+quarantine.
+
+## PromotionStore
+
+`PromotionStore` becomes vestigial. It may remain temporarily as a derived
+runtime compatibility/index layer for existing consumers, but it is not
+serialized authority, must not create promotions without linked
+`SubgraphInput`s, and should be removed once consumers query the standard graph
+interface directly.
+
+## Considered options
+
+### Keep `proxyWidgets` as canonical serialized topology
+
+Rejected. This preserves two representations for the same concept and keeps
+source-widget identity in the value-ownership path.
+
+### Preserve bare promoted widgets as degraded runtime state
+
+Rejected. This would avoid some migration complexity, but it perpetuates the
+ambiguity that caused host/source value bugs and makes ECS identity less clear.
+
+### Quarantine primitive-node promotions by default
+
+Rejected. Primitive-node proxy promotions are expected legacy workflows, and
+quarantining them would break users unnecessarily. They are repaired by bypassing
+the primitive node when the repair can be validated all-or-nothing.
+
+### Migrate `widgets_values` to object/map form now
+
+Rejected for this slice. Name-keyed object form is the desired long-term
+direction, but combining it with the promotion migration increases blast radius
+for existing workflow consumers that still assume array order.
+
+## Consequences
+
+- Promoted widget values become host-instance-owned and ECS-compatible.
+- Source widgets remain metadata/default providers, not persistence carriers.
+- Legacy workflows are repaired toward one standard representation.
+- Quarantine preserves unrepaired valid legacy data without reintroducing bare
+  runtime promotion.
+- Primitive fanout repair is more complex, but avoids breaking common existing
+  workflows.
+- UI code must migrate with the runtime migration to avoid mixed identity states.
+- `PromotionStore` has a clear removal path.

+# Appendix: Before and after flows
+
+This appendix visualizes the ownership and migration flows described in
+[ADR 0009](../0009-subgraph-promoted-widgets-use-linked-inputs.md).
+
+## Before: proxy widgets and linked inputs overlap
+
+Historically, promoted widgets could be represented both as serialized
+`properties.proxyWidgets` entries and as linked subgraph inputs. Runtime value
+reads could collapse back to the interior source widget, while host
+`widgets_values` could also carry an exterior value for the same promoted UI.
+
+```mermaid

+
+  class proxyWidgets,promotionStore legacy
+  class sourceWidget,hostValues ambiguous
+  class linkedInput,hostWidget canonical
+```
+
+Key problems in the old flow:
+
+- `properties.proxyWidgets` and linked `SubgraphInput` widgets could describe
+  the same promotion.
+- Interior source widgets supplied both schema metadata and, in some flows,
+  persisted host values.
+- Multiple host instances of the same subgraph could stomp one another through
+  the shared interior widget value.
+- Display-only previews were mixed into widget-promotion language even though
+  they do not own values or feed prompt serialization.
+
+## After: linked inputs are the promoted-widget boundary
+
+Promoted value widgets are now represented only as standard linked
+`SubgraphInput` widgets. The source widget remains the schema/default provider,
+but the host `SubgraphNode` owns the promoted value.
+
+```mermaid
+flowchart TD
+  workflow[Workflow JSON] --> subgraphInterface[Subgraph interface / inputs]
+  workflow --> hostValues[host widgets_values]
+  subgraphInterface --> subgraphInput[SubgraphInput.name]
+  subgraphInput --> hostWidget[Host-scoped widget entity]

+
+  class subgraphInterface,subgraphInput,hostWidget,hostIdentity owner
+  class sourceWidget,schema,diagnostics metadata
+  class workflow,hostValues persisted
+```
+
+Canonical ownership after the migration:
+
+- UI/value identity is host-scoped: host node locator plus
+  `SubgraphInput.name`.
+- `SubgraphInput.name` is stable identity; labels and localized names are
+  display-only.
+- Host values win during repair, persistence, and prompt serialization.
+- Source widgets provide metadata and defaults only.
+- Canonical saves omit repaired `properties.proxyWidgets` entries.
+
+## Legacy load migration
+
+Loading a workflow with legacy `proxyWidgets` performs an idempotent repair. The
+repair builds a plan before mutating graph state, then re-resolves against the
+current graph when node IDs and links are stable.

+
+## Preview exposures are separate from value widgets
+
+Display-only previews, such as `$$canvas-image-preview`, are not promoted
+widgets. They have host-scoped serialized identity, but they do not create
+prompt inputs, do not create `widgets_values`, and do not own user values.

+# Appendix: Removing `disambiguatingSourceNodeId`
+
+This appendix explains where the existing promotion system needs
+`disambiguatingSourceNodeId`, why that need appears, and how the canonical form
+chosen by [ADR 0009](../0009-subgraph-promoted-widgets-use-linked-inputs.md)
+removes the pattern from promoted-widget identity.
+
+## Why the disambiguator exists
+
+The legacy promotion model identifies a promoted widget by source location:
+
+```ts
+type PromotedWidgetSource = {
+  sourceNodeId: string
+  sourceWidgetName: string
+  disambiguatingSourceNodeId?: string
+}
+```
+
+`sourceNodeId` is the immediate interior node visible from the host subgraph.
+That is not always the original widget owner. When promotions pass through
+nested subgraphs, two promoted widgets can have the same immediate
+`sourceNodeId` and `sourceWidgetName` while pointing at different leaf widgets.
+`disambiguatingSourceNodeId` carries the deepest source node ID so the runtime
+can choose the right promoted view.
+
+```mermaid
+flowchart TD
+  outerHost[Outer host SubgraphNode] --> middleNode[Interior middle SubgraphNode]
+  middleNode --> middleWidgetA[Promoted widget view: text]
+  middleNode --> middleWidgetB[Promoted widget view: text]
+  middleWidgetA --> leafA[Leaf source node 17 / widget text]
+  middleWidgetB --> leafB[Leaf source node 42 / widget text]
+
+  oldKeyA[Old key: middleNodeId + text + disambiguatingSourceNodeId 17]
+  oldKeyB[Old key: middleNodeId + text + disambiguatingSourceNodeId 42]
+  middleWidgetA -. requires .-> oldKeyA
+  middleWidgetB -. requires .-> oldKeyB
+
+  classDef host fill:#d1e7dd,stroke:#0f5132,color:#052e16
+  classDef ambiguous fill:#fff3cd,stroke:#a66f00,color:#332200
+  classDef leaf fill:#cff4fc,stroke:#055160,color:#032830
+
+  class outerHost host
+  class middleNode,middleWidgetA,middleWidgetB,oldKeyA,oldKeyB ambiguous
+  class leafA,leafB leaf
+```
+
+The disambiguator is therefore not a domain concept. It is compensating for an
+identity model that asks host UI state to identify private nested internals.
+
+## Existing places that need it
+
+| Area                         | Current use of `disambiguatingSourceNodeId`                                                                                                   | Ambiguity being patched                                                                             |
+| ---------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------- |
+| Promotion source types       | `PromotedWidgetSource` and `PromotedWidgetView` carry the optional field.                                                                     | Source identity needs more than immediate node ID plus widget name for nested promoted views.       |
+| Concrete widget resolution   | `findWidgetByIdentity(...)` matches promoted views by `(disambiguatingSourceNodeId ?? sourceNodeId)` when a source node ID is supplied.       | Multiple promoted views under the same intermediate node can share a widget name.                   |
+| Legacy proxy normalization   | Prefixed legacy names such as `123:widget_name` are converted into structured source identity and tested with candidate disambiguators.       | Old serialized names encode leaf identity inside the widget name string.                            |
+| Promotion store keys         | `makePromotionEntryKey(...)`, `isPromoted(...)`, and `demote(...)` include the field in equality.                                             | Store-level uniqueness would collapse distinct nested promotions without the leaf ID.               |
+| Linked promotion propagation | `SubgraphNode._resolveLinkedPromotionBySubgraphInput(...)` preserves the leaf ID when a linked input targets an inner subgraph promoted view. | The outer host otherwise sees only the immediate inner `SubgraphNode` and the promoted widget name. |
+| Subgraph editor UI           | The editor uses the field when resolving active widgets and when writing reordered/toggled promotions back to the store.                      | UI list operations must not merge same-name promoted views from different leaves.                   |
+
+## New promoted-widget identity
+
+ADR 0009 moves promoted value identity to the host boundary:
+
+```ts
+type PromotedWidgetUiIdentity = {
+  hostNodeLocator: string
+  subgraphInputName: string
+}
+```
+
+The canonical widget is owned by a `SubgraphInput` on the host
+`SubgraphNode`. The host widget no longer needs to identify the deepest source
+node to preserve value identity. The source widget is consulted for schema,
+defaults, diagnostics, and migration, but it is not the value owner.
+
+```mermaid
+flowchart TD
+  host[Host SubgraphNode] --> inputA[SubgraphInput.name: prompt]
+  host --> inputB[SubgraphInput.name: negative_prompt]
+  inputA --> hostWidgetA[Host-owned widget entity]
+  inputB --> hostWidgetB[Host-owned widget entity]
+
+  hostWidgetA -. schema/default metadata .-> sourceA[Interior source widget text]
+  hostWidgetB -. schema/default metadata .-> sourceB[Interior source widget text]
+
+  identityA[Identity: hostNodeLocator + prompt] --> hostWidgetA
+  identityB[Identity: hostNodeLocator + negative_prompt] --> hostWidgetB
+  sourceA -. not part of host value key .-> identityA
+  sourceB -. not part of host value key .-> identityB
+
+  classDef owner fill:#d1e7dd,stroke:#0f5132,color:#052e16
+  classDef metadata fill:#cff4fc,stroke:#055160,color:#032830
+  classDef removed fill:#f8d7da,stroke:#842029,color:#330000
+
+  class host,inputA,inputB,hostWidgetA,hostWidgetB,identityA,identityB owner
+  class sourceA,sourceB metadata
+```
+
+This is the same rule the subgraph interface already uses: `name` is stable
+identity, and `label` / `localized_name` are display-only.
+
+## How the new form removes each need
+
+| Previous disambiguation site                      | New canonical replacement                                                                                                         |
+| ------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------- |
+| `PromotedWidgetSource.disambiguatingSourceNodeId` | Host value identity is `hostNodeLocator + SubgraphInput.name`; source locator fields become migration/diagnostic metadata only.   |
+| `PromotedWidgetView.disambiguatingSourceNodeId`   | Host-scoped widget entities are derived from subgraph inputs, not from promoted views chained through nested source widgets.      |
+| `findWidgetByIdentity(...)` leaf matching         | Runtime value lookup starts from the host input identity; source traversal is metadata resolution, not value identity resolution. |
+| Legacy prefixed widget-name normalization         | Load migration consumes legacy source-shaped entries and writes standard subgraph input state or quarantine metadata.             |
+| PromotionStore source-key equality                | `PromotionStore` becomes a temporary derived index; canonical consumers query subgraph inputs directly.                           |
+| Linked promotion propagation across nested hosts  | Nested value composition is represented boundary-by-boundary by linked subgraph inputs with stable names.                         |
+| Subgraph editor active widget matching            | Editor state can operate on host boundary entries instead of matching leaf source widgets through same-name promoted views.       |
+
+## Boundary-by-boundary nested flow
+
+The new form avoids flattened deep source paths. Each host boundary exposes its
+own named input, and the next outer host links to that immediate boundary
+contract.
+
+```mermaid
+flowchart LR
+  leaf[Leaf node widget] --> innerInput[Inner SubgraphInput.name: text]
+  innerInput --> innerHostWidget[Inner host-owned widget]
+  innerHostWidget --> outerInput[Outer SubgraphInput.name: prompt]
+  outerInput --> outerHostWidget[Outer host-owned widget]
+
+  innerIdentity[Inner value key: innerHost + text] --> innerHostWidget
+  outerIdentity[Outer value key: outerHost + prompt] --> outerHostWidget
+  leaf -. schema/default source .-> innerHostWidget
+  leaf -. not persisted as outer value key .-> outerIdentity
+
+  classDef boundary fill:#d1e7dd,stroke:#0f5132,color:#052e16
+  classDef source fill:#cff4fc,stroke:#055160,color:#032830
+  classDef note fill:#fff3cd,stroke:#a66f00,color:#332200
+
+  class innerInput,innerHostWidget,outerInput,outerHostWidget,innerIdentity,outerIdentity boundary
+  class leaf source
+```
+
+Because each layer has its own stable `SubgraphInput.name`, two same-name leaf
+widgets no longer require a persisted leaf-node disambiguator at the outer host.
+If the user exposes both, the collision is resolved when the host inputs are
+created by assigning distinct input names with the existing unique-name
+behavior.

+| Primitive-node promotions  | Legacy tuples may point at `PrimitiveNode` outputs.                                                      | Not the canonical primitive fanout representation by itself.                                     | Repaired all-or-nothing into one `SubgraphInput` that reconnects validated fanout targets.                  |
+| Invalid or unresolved data | Invalid data could sit in legacy promotion state or fail repair paths.                                   | Missing linked inputs can be ambiguous when proxy data exists.                                   | Invalid raw data logs and is ignored; unrepaired valid value entries go to `proxyWidgetErrorQuarantine`.    |
+| Display-only previews      | Often mixed into `proxyWidgets` despite not being value widgets.                                         | Linked inputs are inappropriate because previews do not own values or prompt inputs.             | Separate host-scoped `properties.previewExposures` entries model preview UI only.                           |
+| Preview persistence        | Preview selections can depend on source preview/widget-like identity.                                    | No clean distinction from promoted widget inputs.                                                | Preview identity is host node locator plus `previewName`; unresolved previews stay inert and persisted.     |
+| Nested preview behavior    | Deep source identity can leak through host UI state.                                                     | Linked value inputs do not model display-only preview composition.                               | Preview exposures chain across immediate subgraph host boundaries; deep private paths are not persisted.    |
+| ECS compatibility          | Weak: value identity can depend on source widget tuples and mutable interior widgets.                    | Partial: linked inputs fit boundary modeling, but duplicate authority remains.                   | Strong: host-scoped widget entity identity maps cleanly to ECS component state.                             |
+| Long-term status           | Legacy load-time input only.                                                                             | Becomes the standard representation once overlap is removed.                                     | Canonical system; `PromotionStore` becomes a temporary derived compatibility/index layer.                   |

+# 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
+      |                      |                   |
+      |  defineNode({...})   |                   |
+      |--------------------->|                   |
+      |     (push to array)  |                   |
+      |                      |                   |
+      |                      | startExtensionSystem()
+      |                      |------------------>|
+      |                      |   (watch for NodeType entities)
+      |                      |                   |
+      |                      |   NodeType added  |
+      |                      |<------------------|
+      |                      |                   |
+      |                      | mountExtensionsForNode(id)
+      |                      |   (runs setup)    |
+```
+
+## 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.

+# 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.
