refactor: migrate remaining first-party readers off deprecated slot mirrors

The deprecation getters fired for every user on the first rendered
frame, making extension telemetry meaningless. drawConnections now does
one pass over graph links instead of per-node per-input getter scans;
the subgraph resolvers take the input from link.resolve() they already
call; findInputByType and unpackSubgraph use the slotLinks helpers.
Adds the missing coverage: getter read/write behavior for both mirrors,
the slotLinks input trio, and a connect-draw-serialize cycle asserting
no deprecation warning fires.

+Two stores joined the dedicated-store set: `linkStore` (link topology,

+`rerouteStore` (reroute chain state with link membership derived from

+follow the proxy-returning registration pattern established by

+registration inserts the class's state object by reference and the class
+adopts the reactive proxy read back from the bucket, so class field
+writes are tracked without an action chokepoint. The `layoutStore` link
+connectivity mirror and the `slot._floatingLinks` sets were deleted in
+the same work; the layout store now holds geometry only.

 ## Context
 
 The litegraph layer is built on deeply coupled OOP classes (`LGraphNode`, `LLink`, `Subgraph`, `BaseWidget`, `Reroute`, `LGraphGroup`, `SlotBase`). Each entity directly references its container and children — nodes hold widget arrays, widgets back-reference their node, links reference origin/target node IDs, subgraphs extend the graph class, and so on.

+[Link Topology Store](link-topology-store.md),

+[Node Badge Store](node-badge-store.md),
+[ADR 0008](../adr/0008-entity-component-system.md).
+
+## Badges
+
+- **Badge** — a small visual annotation rendered on a node: its numeric
+  id, lifecycle state, source pack, execution price, or an
+  extension-provided marker. Badges are presentation state; they never
+  affect execution and are never persisted with the workflow.
+- **Badge kind** — the category a badge belongs to: **core** (identity /
+  lifecycle / source, projected from the node's definition and user
+  settings), **credits** (price of executing an API node, including
+  aggregated prices of nodes inside a subgraph), or **extension**
+  (provided by third-party code).
+- **Badge source** — the domain state a badge's content is computed
+  from (settings, node definition, palette, pricing, widget values,
+  input connectivity). A badge is always a projection of its sources;
+  it is never authored directly by a user.
+
+## Links & Reroutes
+
+- **Link** — a directed data connection from one node's output slot to
+  another node's input slot. At most one live link targets a given input
+  slot.
+- **Floating link** — a link with exactly one attached endpoint, kept
+  alive so a reroute chain survives disconnection. The unattached end is
+  unassigned.
+- **Reroute** — a visual waypoint that a link's rendered path travels
+  through. Purely organisational; never affects data flow. A reroute's
+  identity is unique within a workflow, subgraphs included.
+- **Reroute chain** — the ordered sequence of reroutes a link passes
+  through, from the node output toward the input. Each reroute names its
+  upstream neighbour via _parent_; the link names the chain's most
+  downstream reroute (the **terminal reroute**).
+- **Link membership (of a reroute)** — the set of links whose chains pass
+  through that reroute. Membership is _defined by_ the chains: a link is a
+  member of exactly the reroutes on the chain walked from its terminal
+  reroute upstream. It is never authored independently of the chain.
+- **Floating slot marker** — the annotation on the last reroute of a
+  floating chain recording which side (input or output) the chain still
+  faces.

 Problems: two-phase creation is necessary because nodes need to reference each other's links during configure. Widget value restoration happens deep inside `node.configure()`. Store population is a side effect of configuration. Subgraph creation requires topological sorting to handle nested subgraphs.
 
+Note on load-time id hygiene: root `configure()` deduplicates **node ids** and **reroute ids** across sibling subgraph definitions before configuring them (`deduplicateSubgraphNodeIds` / `deduplicateSubgraphRerouteIds`), because both share root-graph-scoped store buckets. Link-id dedup is deliberately absent — the linkStore key is the target input slot, not the link id, so duplicate link ids across definitions cannot collide. Orphaned reroutes are pruned by the derived `totalLinks === 0` check; the old `validateLinks` set-repair is gone (membership is derived, so there is no stored set to drift).

+# Link Topology Store
+
+Date: 2026-07-05 (retroactive design record; implemented in PR #13436)
+Status: Accepted
+
+Design record for extracting link topology into a dedicated store per
+[ADR 0008](../adr/0008-entity-component-system.md). Amends the
+`LinkEndpoints` component described there. The
+[Reroute Chain Store](reroute-chain-store.md) builds directly on this
+store; shared vocabulary lives in the
+[Domain Glossary](domain-glossary.md).
+
+## Decision 1: One state object, class reads through it
+
+`LLink` no longer owns copies of its topology fields. A single plain
+object,
+
+```
+LinkTopology { id, originNodeId, originSlot, targetNodeId, targetSlot,
+               type, parentId? }
+```
+
+backs the link: `LLink._state` holds it, and `id`, `type`, `origin_id`,
+`origin_slot`, `target_id`, `target_slot`, and `parentId` are accessors
+over it. Registration inserts that same object into the store by
+reference and re-assigns `_state` to the reactive proxy read back from
+the bucket, so subsequent class writes are Vue-tracked (the `BaseWidget`
+pattern — see Decision 4 of the reroute chain store record). There is no
+store-side copy to drift from the class: the store entry _is_ the
+class's state.
+
+The store is runtime state only; `LLink.asSerialisable` reads the same
+fields it always did, and serialization goldens (key order plus
+byte-identical round-trips) pin the wire format.
+
+## Decision 2: Keyed by target input slot, not link id
+
+The primary index is keyed by `` `${targetNodeId}:${targetSlot}` ``.
+Two facts make this the right key:
+
+- **The domain invariant**: at most one live link targets a given input
+  slot. The key is unique by construction for live links.
+- **The dominant query**: consumers ask "is this input slot connected,
+  and by what?" (`isInputSlotConnected`, `getInputSlotLink`). The key
+  answers it in one lookup with no scan.
+
+Link _ids_ are only unique per owning graph, not per root graph, so an
+id-keyed root bucket needed a load-time link-id dedup pass and a
+first-wins registration protocol to survive collisions across sibling
+subgraph definitions. Re-keying by target slot deleted both: colliding
+link ids never touch the index, so workflows load without link-id
+rewrites.
+
+Rejected: keeping the id key plus dedup/first-wins. That machinery
+existed only to compensate for a key the queries never used.
+
+## Decision 3: Root-graph-scoped buckets, unkeyed side set
+
+Buckets are scoped by `rootGraph.id` — subgraphs share their root's
+bucket — matching `widgetValueStore` and the later `rerouteStore`.
+Re-keying entries to their owning graph was evaluated and rejected: it
+reintroduces per-graph lifecycle bookkeeping the root scope avoids, and
+no query wants owning-graph granularity that `graphTopologies` filtering
+doesn't already provide.
+
+Links without a unique live target go in a per-graph side `Set` instead
+of the primary index:
+
+- **Floating links** — exactly one assigned endpoint; the other is
+  `UNASSIGNED_NODE_ID`. A floating link attached to an input slot does
+  not answer `isInputSlotConnected`, preserving `input.link` semantics.
+- **Links targeting `SUBGRAPH_OUTPUT_ID`** — the id is a shared
+  constant, so `targetNodeId:targetSlot` is not unique across the
+  subgraphs sharing a root bucket.
+
+## Decision 4: Registration protocol
+
+- `registerLink` is **first-wins**: if a different topology already
+  holds the target key, the call returns `undefined` and the loser
+  stays detached. `link._graphId` records a won registration; it is the
+  ownership marker that lets `unregisterLink` and re-registration no-op
+  safely for losers.
+- `deleteLink` is **identity-checked** (`toRaw` comparison): only the
+  registered topology can vacate its slot.
+- `updateEndpoint` re-keys atomically — identity-checked displace,
+  patch fields through a reactive wrapper, re-place under the new key —
+  and the move is **authoritative**: an incumbent under the new key is
+  evicted. First-wins only guards _registration_; a re-key is a move of
+  a link that already proved ownership by vacating its old key, so the
+  write wins. This is what keeps slot permutations safe when callers
+  re-key links one write at a time (input reorder, splice shifts): a
+  transiently evicted link re-places itself when its own endpoint write
+  arrives, and every lawful final state is collision-free. The
+  `reactive()` wrap stays even though registered links already hold the
+  proxy: the store is public API and may be handed a raw topology
+  object.
+
+## Decision 5: Mutation chokepoints
+
+All `graph._links` map mutation funnels through `LGraph._addLink` /
+`_removeLink`, which pair the map write with store
+registration/unregistration (and link-layout cleanup on removal).
+`addFloatingLink` / `removeFloatingLink` do the same for the floating
+map. `LLink.disconnect` performs the equivalent effects inline because
+it only holds a `LinkNetwork`, and unregisters before reroute pruning so
+derived reroute counts exclude the dying link. `clear()` and
+subgraph-definition GC unregister whole graphs
+(`unregisterAllLinkTopologies` / `clearGraph`).
+
+## Scope
+
+This design covers link topology (endpoints, type, chain terminus).
+Link visual state (`color`, path caches) and the layout store's link
+_geometry_ records are out of scope. The `output.links` and `input.link`
+slot mirrors have since been deleted — the store is the single source
+for slot connectivity in both directions (see
+[output slot connectivity](output-slot-connectivity.md) Decision 6);
+the remaining fields are deprecated warning getters kept as extension
+migration telemetry.

+# Node Badge Store
+
+Date: 2026-07-05 (updated 2026-07-06)
+Status: Implemented — slice A (store + system) and slice B (consumer
+cutover, resolved decisions below) shipped as
+`src/stores/nodeBadgeStore.ts`, `src/systems/badgeSystem.ts`,
+`src/lib/litegraph/src/nodeBadgeDraw.ts`. Follow-up to the
+[link topology store](link-topology-store.md),
+[reroute chain store](reroute-chain-store.md), and the
+[node data store draft](node-data-store.md)
+
+Design record for extracting node badges off `LGraphNode` instances into
+a dedicated store per [ADR 0008](../adr/0008-entity-component-system.md),
+going straight to plain-data components — no interim closure storage.
+Vocabulary: [domain glossary § Badges](domain-glossary.md#badges).
+
+## Current state (what this replaces)
+
+`LGraphNode.badges: (LGraphBadge | (() => LGraphBadge))[]` mixes three
+things: a **core badge closure** (id / lifecycle / source, re-derived
+independently by the Vue renderer, which skips it positionally via
+`slice(1)`), **credits badge closures** (`creditsBadgeGetter`,
+`buildWrapperAwarePriceBadge` — hand-rolled reactive computeds the
+legacy canvas polls per frame), and a public push surface for
+extensions. Badge changes are announced by a single manual
+`node:property:changed` trigger in `usePriceBadge`; plain pushes are
+invisible. Credits badges are classified by icon identity
+(`icon.image === componentIconSvg`). Badges never serialize (verified:
+no `badges` key in `serialize()`/`configure`).
+
+Every closure is a reactive computed feeding an unreactive array, and
+the Vue renderer has already re-implemented all of their reactivity as
+store-tracked dependencies. The design deletes the closures and makes
+the store rows the single truth both renderers read.
+
+## Decision 1: Plain `BadgeData` rows, no interim shape
+
+The store holds only plain data (ADR 0008 component rule):
+
+```
+BadgeData {
+  kind: 'core' | 'credits' | 'extension'
+  text: string
+  fgColor?: string
+  bgColor?: string
+  iconKey?: string     // resolved via a small icon registry ('credits' → SVG)
+}
+```
+
+No `onClick` (no producer exists; `LGraphButton`/`title_buttons` are a
+separate surface and out of scope). No `Image` objects — icons are
+referenced by key. A `commandId` field can be added if a clickable badge
+requirement ever materialises.
+
+Rejected: an interim `BadgeEntry { kind, source: LGraphBadge | thunk }`
+phase. The public element type of `node.badges` breaks either way; one
+break that lands on the end-state shape beats two.
+
+## Decision 2: Store shape and keying
+
+`nodeBadgeStore`: root-graph-scoped buckets (`rootGraph.id`) keyed by
+`NodeId`, each holding an ordered reactive `BadgeData[]`. Register /
+unregister / unregister-all trio at the `LGraph.add` / `LGraph.remove` /
+`clear()` chokepoints, identity-checked deletes — the shipped store
+conventions.
+
+Rows are partitioned by `kind` at read time; the positional `slice(1)`
+convention and icon-identity credits detection are deleted. Display
+order is kind order (core, credits, extension), not insertion order.
+
+## Decision 3: A reactive BadgeSystem writes the rows
+
+One system module owns the recomputation: per registered node, an
+`effectScope` runs a pure `computeBadges(sources) → BadgeData[]`
+function inside a thin watch shell and writes the node's rows. Sources
+are the existing stores: `nodeDefStore`, `settingStore`,
+`colorPaletteStore`, `useNodePricing` revision refs, `widgetValueStore`,
+`linkStore` input connectivity. The pure function is the future
+command-pipeline phase body (ADR 0003 systems ADR); only the scheduler
+shell changes when that lands.
+
+`useNodeBadge` / `usePriceBadge` stop pushing closures; their derivation
+logic moves into `computeBadges`. The manual `'badges'`
+`node:property:changed` trigger, the `badges` case in
+`useGraphNodeManager`, and `VueNodeData.badges` are deleted.
+`usePartitionedBadges` collapses to a store query partitioned by kind;
+its manual dependency-touching (`trackNodePrice`,
+`trackSubgraphInnerNodePrices`) moves inside the system.
+
+## Decision 4: Core badges are system-written rows too
+
+Core (#id / lifecycle / source) badges are materialized by the system
+like every other kind, so both renderers consume one uniform row set.
+This kills the current dual derivation (legacy closure + Vue-side
+re-derivation). Materialized-by-system is the ECS write path, not a
+mirror: no other component stores this projection.
+
+## Decision 5: Legacy canvas consumes rows via a draw cache
+
+`drawBadges` renders from `BadgeData`, constructing and caching
+`LGraphBadge` draw objects keyed by row content (the `Reroute` id-badge
+pattern, memoized). `_boundingRect` hit-test state stays renderer-side.
+Frame-budget parity per ADR 0008's render mitigations applies.
+
+## Implementation notes (slice A)
+
+- Registration is bucket-key presence: the `LGraph.add`/`remove`/`clear`
+  chokepoints call the import-light store trio
+  (`registerNode`/`unregisterNode`/`clearGraph`), and the system watches
+  `registeredNodeIds` to attach/detach per-node effect scopes. Litegraph
+  never imports the system, so the pricing/nodeDef dependency graph
+  (which runtime-imports the litegraph barrel) stays acyclic. The system
+  takes `resolveGraphId`/`resolveNode` seams and is bootstrapped once at
+  the app layer by the `Comfy.NodeBadge` extension (`useNodeBadge`).
+  The graph id is resolved live on every recompute because
+  `LGraph.clear()` and `configure()` reassign the root graph's id; a
+  captured id strands the system on a dead bucket. Row writes are
+  refused for unregistered nodes so a late effect flush cannot
+  resurrect a bucket key the chokepoints deleted. `LGraph.add`
+  registers the node only after `onNodeAdded`: the store write wakes
+  the system's watcher and queues Vue's flush microtask, which must not
+  overtake the paste-scan microtask `useErrorClearingHooks` enqueues
+  from `onNodeAdded`.
+- The shell still reads `node.constructor.nodeData` and `node.inputs`
+  (untracked instance state) to map pricing input names to slot
+  indices — parity with the legacy closures. Those reads become store
+  lookups when slot data is store-backed (node data store draft).
+- Core rows are fine-grained — one row per part, tagged
+  `part: 'lifecycle' | 'id' | 'source'` and carrying the raw projected
+  text — with one visibility rule (`badgeTextVisible`, the legacy
+  semantics: `HideBuiltIn` respected for every part). Each renderer owns
+  presentation: the legacy draw cache joins parts in id, lifecycle,
+  source order and truncates; the Vue partition trims lifecycle
+  brackets, and replaces a built-in node's source row with its
+  Comfy-logo chip. Known unification effect: the Vue renderer gains
+  `HideBuiltIn` handling for id and lifecycle badges on built-in nodes.
+- A credits row is emitted only when the display price label is
+  non-empty; async pricing fills it via the per-node revision ref.
+
+## Implementation notes (slice B)
+
+- Wrapper `SubgraphNode` credits rows are aggregated by the system over
+  the inner (recursively collected, non-wrapper) api nodes — the same
+  count basis as the old unconditional per-api-node badges: several
+  collapse to `Partner Nodes x N` (localized), exactly one shows its
+  price with the wrapper's promoted widget values overriding the inner
+  node's own. The aggregation tracks the inner nodes' pricing
+  revisions, the registered-node set, and a structure revision.
+  `useNodePricing` caches labels per signature so a leaf's own read and
+  its wrapper's override read do not evict each other and re-schedule
+  forever.
+- Legacy `drawBadges` renders the store rows through a per-node
+  memoized `LGraphBadge` cache (decision 5); `iconKey` resolves through
+  a generic litegraph `badgeIconRegistry`, with the `credits` icon
+  registered by the system module.
+
+## Resolved decisions (2026-07-06 interview)
+
+1. **Legacy `node.badges` surface — kept as a raw extension-only push
+   surface.** Directive: delete unless actively used. A GitHub-wide scan
+   found three custom-node packs actively writing it
+   (ComfyUI-Wildcard-Pipeline pushes and splices `LGraphBadge`
+   instances; ComfyUI-Enhancement-Utils and ComfyUI-XENodes push
+   per-frame getter thunks for ticking execution-time badges), so the
+   array stays, is no longer written by core/credits code, and both
+   renderers append it after the store rows — thunks still evaluate per
+   frame in the legacy canvas. The earlier "zero third-party writers"
+   scan was wrong.
+2. **`node.badgePosition` — deleted**, along with the `BadgePosition`
+   enum. Zero uses outside this repo; the legacy canvas now always
+   renders badges top-right (the only surviving behaviour).
+3. **Subgraph credits aggregation triggers — event-bumped revision.**
+   `litegraph:set-graph`, `subgraph-converted`, and
+   `afterConfigureGraph` bump `bumpSubgraphCreditsRevision()`; swap to
+   reactive `SubgraphStructure` dependencies when that state is
+   store-backed. Aggregation behaviour itself is preserved (explicit
+   user requirement).
+
+## Scope and sequencing
+
+Slices: (A) store + `BadgeData` + system for core and credits +
+chokepoint registration; (B) consumer cutover — Vue partition query,
+legacy draw cache, trigger/`VueNodeData.badges` deletions, legacy
+surface shim; extension-facing deprecation notes. Independent of the
+pending `nodeDataStore` extraction and lands before it, shrinking its
+Decision 4/6 scope (one less `VueNodeData` field, one less property
+handler). `PartnerNodesList`'s `find(isCreditsBadge)` migrates to a
+store query by kind.

+# Node Data Store
+
+Date: 2026-07-05
+Status: Draft (design interview in progress; follow-up to the
+[link topology store](link-topology-store.md) and
+[reroute chain store](reroute-chain-store.md))
+
+Design record for extracting the remaining Node-owned components into a
+dedicated store per [ADR 0008](../adr/0008-entity-component-system.md),
+eliminating the `VueNodeData` mirror and most of
+`src/composables/graph/useGraphNodeManager.ts`.
+
+## Decision 1: One store, one plain state object per node
+
+`nodeDataStore` holds a single plain `NodeState` object per node,
+registered by reference with proxy-returning registration (the
+`BaseWidget` pattern, [reroute store Decision 4](reroute-chain-store.md)).
+ADR 0008's Node component rows (`NodeVisual`, `Execution`, ...) become
+field groupings inside `NodeState`, not separate records or stores.
+
+Buckets are root-graph-scoped (`rootGraph.id`), keyed by `NodeId`.
+Node-id uniqueness across sibling subgraph definitions is already
+guaranteed by the load-time dedup pass
+(`src/lib/litegraph/src/subgraph/subgraphDeduplication.ts`).
+
+## Decision 2: Field set — what is NodeState, what is elsewhere
+
+```
+NodeState {
+  id: NodeId
+  graphId: UUID            // owning (sub)graph — partitioning + locator ids
+  type: string             // identity, with apiNode?: boolean
+  title: string
+  titleMode?: TitleMode
+  mode: number
+  flags: { collapsed?, pinned?, ghost? }
+  color?: string
+  bgcolor?: string
+  shape?: number
+  resizable?: boolean
+  showAdvanced?: boolean
+}
+```
+
+Excluded — owned or derived elsewhere; referencing them here would be a
+mirror (the hard constraint of this phase):
+
+| Field                   | Owner                                                                                                                                                  |
+| ----------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| `selected`              | `canvasStore.selectedNodeIds` (already what `LGraphNode.vue` reads)                                                                                    |
+| `executing`             | `executionStore` via `useNodeExecutionState` (already what Vue reads)                                                                                  |
+| `hasErrors`             | derived from `executionErrorStore` / missing-model/media stores; `node.has_errors` stays a legacy-canvas class field written by `useNodeErrorFlagSync` |
+| position / size / z     | `layoutStore`                                                                                                                                          |
+| widget values / order   | `widgetValueStore`                                                                                                                                     |
+| input link connectivity | `linkStore` (`getInputSlotLink` / `isInputSlotConnected`)                                                                                              |
+| `badges`                | `nodeBadgeStore` — plain `BadgeData` rows written by a badge system; see [Node Badge Store](node-badge-store.md)                                       |
+| `inputs` / `outputs`    | deferred — see Decision 3                                                                                                                              |
+
+`VueNodeData.selected` and `.executing` are dead fields today (no
+production consumer reads them); they are deleted, not migrated.
+
+## Decision 3: Slot arrays deferred; `inputs[].link` readers migrate now
+
+`NodeInputSlot` / `NodeOutputSlot` are class instances with methods —
+Slot entity extraction (ADR 0008 `SlotIdentity` etc.) is its own future
+phase. The slot arrays stay class-side, keeping the `shallowReactive`
+graft for renderer reactivity.
+
+What this phase does remove is the last `inputs[].link` dependency: the
+three remaining readers (`nodeDataUtils.linkedWidgetedInputs` used by
+`NodeSlots`, and `usePartitionedBadges`' badge computed plus its
+exported `trackNodePrice`) move to `linkStore.isInputSlotConnected`
+queries — presence is all any of them needed — which deletes the
+`node:slot-links:changed` → `refreshNodeInputs` reprojection in
+`useGraphNodeManager`, the dead `node:slot-errors:changed` handler
+(zero emitters repo-wide), and the node-removal refresh-all loop.
+Shipped ahead of the store itself (2026-07-05).
+
+## Decision 4: Renderer consumes the NodeState proxy, `VueNodeData` dies
+
+`GraphCanvas` iterates the store's bucket for the active graph (filtered
+by `NodeState.graphId`) and passes the reactive `NodeState` proxy down
+the existing prop-drilling path (`LGraphNode` → `NodeHeader` /
+`NodeSlots` / `NodeContent` / `NodeWidgets`). Children read proxy fields
+directly; Vue tracks the store state, so the per-property
+`node:property:changed` → snapshot-rewrite handlers in
+`useGraphNodeManager` are deleted wholesale.
+
+Slot arrays reach `NodeSlots` via the existing live-node access
+(`getNodeByLocatorId`), not through `NodeState`.
+
+`LGraphNodePreview` constructs a synthetic `NodeState` (as it does a
+synthetic `VueNodeData` today). `AppModeWidgetList` stops calling
+`extractVueNodeData` and reads the registered `NodeState` + live node.
+
+## Decision 5: Registration lifecycle and class adoption
+
+Follows the shipped trio convention (`LLink` / `Reroute`):
+
+- `LGraphNode` constructs its `_state: NodeState` at instantiation;
+  `registerNodeState(graph, node)` inserts it by reference and the class
+  adopts the returned reactive proxy; `node._graphId` (root id) is the
+  registration-ownership marker.
+- Chokepoints: `LGraph.add` / `LGraph.remove` (the canonical sites),
+  `unregisterAllNodeStates(graph)` on graph `clear()`, identity-checked
+  delete (`toRaw` compare) so only the registered state vacates its key.
+- Class fields become accessors reading through `_state`.
+  `LGraphNodeProperties`' instrumented descriptors keep their
+  get/set + `node:property:changed` emission but store the value in
+  `_state` instead of a closure — trigger consumers (minimap,
+  `useErrorClearingHooks`) keep working unchanged.
+- Serialization is unaffected: `serialize()` reads the same properties
+  through the accessors.
+
+## Decision 6: What remains of useGraphNodeManager
+
+Deleted: `extractVueNodeData`, the `vueNodeData` map, all
+`node:property:changed` handlers, `syncWithGraph`, `getNode()`
+(consumers use `graph.getNodeById`), the `node:slot-links:changed`
+handler (Decision 3).
+
+Remaining renderer-side lifecycle, slimmed into `useVueNodeLifecycle`
+(or a small successor):
+
+- layoutStore seeding on node add/remove (`createNode`/`deleteNode`
+  layout mutations, including the `onAfterGraphConfigured` deferral) —
+  layout is renderer policy, not entity data.
+- `node:slot-label:changed` slot-array reprojection — dies with the
+  Slot extraction phase.
+
+## Scope
+
+Covers node shell state, the `VueNodeData` deletion, and the
+`inputs[].link` reader migration. Out of scope: Slot entity extraction,
+`Properties` (`properties` / `properties_info`) and `NodeType` metadata
+beyond `type`/`apiNode` (`category`, `nodeData`, `description` remain on
+the class/constructor), badges, `WidgetContainer` (already owned by
+`widgetValueStore`), and command-pattern mutators (future work per
+ADR 0003/0008).

+# Output Slot Connectivity
+
+Date: 2026-07-06
+Status: Accepted (follow-up to the
+[link topology store](link-topology-store.md); the minimal, non-breaking
+slice of the deferred `SlotConnection` component work in the
+[ECS migration plan](ecs-migration-plan.md))
+
+Design record for answering "is this output slot connected, and by what
+links?" from `linkStore` instead of the `output.links[]` mirror. It is
+the output-side counterpart to the input-side migration shipped in
+[node-data-store Decision 3](node-data-store.md) (#13455). Wiring it lets
+`SlotConnectionDot` show connected state and removes the last renderer
+dependency on `output.links[]`.
+
+This phase does not extract a Slot entity, add a store, or delete any
+mirror field. Those stay in the deferred `SlotConnection` phase. What it
+does is the smallest change that clears the reader debt and lets the
+output dot show connection state.
+
+## Motivation
+
+`SlotConnectionDot.vue` colors slots by type only. It carries a
+`//TODO Support connected/disconnected colors?`. `InputSlot` and
+`OutputSlot` already declare `connected` / `compatible` props and apply
+the `lg-slot--connected` / `lg-slot--compatible` classes, but
+`NodeSlots.vue` passes neither, so the styling path is built but unwired.
+
+Input connectivity is already answerable through
+`linkStore.isInputSlotConnected` (shipped in #13455). The matching output
+query does not exist yet, so the output dot cannot be wired and
+`output.links[]` stays the only source. This phase adds that query and
+consumes it.
+
+## Decision 1: Extend `linkStore`, do not add a store or a Slot entity
+
+Output connectivity is link topology: the mirror image of the input side
+the store already owns. It belongs in `linkStore`, not a new `slotStore`.
+A dedicated Slot store (plain `SlotIdentity` / `SlotVisual` rows, retiring
+the slot class instances) is the full `SlotConnection` phase and is out
+of scope here. Introducing it now would be premature per the
+node-data-store record, which keeps the slot arrays class-side.
+
+This phase adds read-only accessors over state the store already holds.
+It needs no new plain-data component, registration trio, chokepoint, or
+class adoption, though each sibling store required all four.
+
+## Decision 2: Output connectivity is a derived reverse index
+
+The store already exposes `graphTopologies(graphId)` over every
+registered `LinkTopology`. "Which links leave output slot _(node, slot)_"
+is a reverse index over origin endpoints. This is the same pattern
+`rerouteStore` uses for link membership
+([reroute store](reroute-chain-store.md)): a per-graph cached `computed`
+that Vue invalidates when link state changes. Nothing is stored, so the
+membership is always derived and cannot drift from the topology.
+
+```ts
+type OriginIndex = Map<
+  OriginSlotKey /* `${originNodeId}:${originSlot}` */,
+  Set<LinkTopology>
+>
+
+const outputIndexes = new Map<UUID, ComputedRef<OriginIndex>>()
+
+function outputIndex(graphId: UUID): ComputedRef<OriginIndex> {
+  const existing = outputIndexes.get(graphId)
+  if (existing) return existing
+  const next = computed(() => {
+    const index: OriginIndex = new Map()
+    for (const t of graphTopologies(graphId)) {
+      if (t.originNodeId === UNASSIGNED_NODE_ID) continue
+      const key = originKey(t.originNodeId, t.originSlot)
+      const links = index.get(key) ?? new Set<LinkTopology>()
+      links.add(t)
+      index.set(key, links)
+    }
+    return index
+  })
+  outputIndexes.set(graphId, next)
+  return next
+}
+```
+
+The index spans both collections that `graphTopologies` yields, the keyed
+targets and the unkeyed side set, so a floating link with an assigned
+origin (one endpoint only) still reports its output as connected. A
+`SUBGRAPH_INPUT_ID` origin indexes like any other id.
+
+## Decision 3: Two public queries, mirroring the input pair
+
+```ts
+isOutputSlotConnected(graphId, nodeId, slot): boolean
+getOutputSlotLinks(graphId, nodeId, slot): ReadonlySet<LinkTopology>
+```
+
+These match `isInputSlotConnected` / `getInputSlotLink` in name and shape.
+The input side returns a single `LinkTopology`, since at most one link
+targets an input; the output side returns a set, since an output fans out
+to many. The set holds topologies rather than bare `LinkId`s: floating
+links draw their ids from a separate counter (`_lastFloatingLinkId`), so
+an id alone cannot be resolved safely through `graph.links` — a floating
+id can collide with an unrelated regular link. Topologies carry the
+endpoints most readers want and make floating links identifiable
+(`targetNodeId === UNASSIGNED_NODE_ID`) without resolution.
+
+## Decision 4: Migrate readers incrementally, keep the mirror written by hand
+
+This follows the #13455 discipline for `input.link`: move the readers to
+the store, leave the field in place, and keep writing it at the
+chokepoints.
+
+`output.links[]` has roughly 200 read sites but only about 12 write
+sites, all in `LGraphNode`, `LGraph`, and the subgraph paths. Most of the
+reads are litegraph-internal graph algorithms such as traversal, dedup,
+and serialization. Those can keep reading the mirror indefinitely; they
+are not renderer policy and nothing blocks on them.
+
+Migrated readers: the output dot's connected state (`NodeSlots`), the
+minimap link extraction (`AbstractMinimapDataSource`), the drag-start
+disconnect check (`useSlotLinkInteraction`, where one store query replaces
+a mirror read plus a `slotFloatingLinks` scan), widget value propagation
+(`widgetValuePropagation`), and matchType link revalidation
+(`dynamicWidgets.changeOutputType`).
+
+## Decision 6: Delete the mirrors (implemented; extended to `input.link`)
+
+The runtime `output.links[]` field and all nine of its write sites are
+deleted. The same recipe has since been applied to `input.link`: the
+field is a deprecated warning getter, litegraph and app code read through
+the slotLinks input helpers (`inputHasLink`, `inputLinkId`, `inputLink`)
+or `node.isInputConnected` / `node.getInputLink`, serialization derives
+`inputs[].link` from the store, and the mirror-carried association
+shuffles were reworked — `fixLinkInputSlots` consumes the serialized
+graph data, dynamicWidgets' group rebuilds carry slot→link association
+in a module-scoped WeakMap refreshed from the store, and link
+deduplication selects survivors from the store registration (the
+`repairInputLinks` mirror repair is gone; the derived view cannot be
+wrong). The store is the single source; litegraph internals read through
+the pure helpers in `node/slotLinks.ts` (`outputHasLinks`,
+`outputLinkIds`, `outputLinks`), and `NodeOutputSlot.isConnected`,
+`serialize`, and `configure` derive from the store. Details:
+
+- **Wire format unchanged.** `outputAsSerialisable` / `toJSON` emit the
+  serialized `outputs[].links` array from the store, sorted ascending by
+  id (a determinism choice — equal to push order for organically built
+  graphs) and `null` when empty. `configure` fires its output
+  `onConnectionsChange` callbacks from the serialized argument.
+- **Floating links are never returned by link queries.** They are
+  reroute-chain scaffolding, named by `isFloatingTopology`
+  (`src/types/linkTopology.ts`). `isOutputSlotConnected` /
+  `getOutputSlotLinks` see fully-assigned links only, matching the
+  mirror they replace; the one consumer with legacy floating-aware
+  behavior (the slot-drag disconnect check) keeps its own
+  `slotFloatingLinks` scan.
+- **Extension compat = deprecation telemetry, not compatibility.** A
+  read-only prototype getter on `NodeOutputSlot` returns a fresh
+  store-derived `LinkId[] | null` and fires `warnDeprecated`. Writes fire
+  their own `warnDeprecated` naming the replacement APIs
+  (`node.connect()` / `node.disconnectOutput()`) and are otherwise
+  ignored — the store stays authoritative and legacy writers degrade
+  gracefully instead of crashing. A bare accessor-only property would
+  instead throw an unactionable `TypeError` in strict mode.
+  `INodeOutputSlot` keeps `links` as `@deprecated readonly` so
+  `'links' in slot` discriminants still compile and hold at runtime via
+  the prototype. The mirror keys are non-enumerable: `{ ...slot }`,
+  `Object.assign({}, slot)`, and `Object.keys(slot)` do not carry
+  `link` / `links` (use the store queries to snapshot connectivity);
+  `JSON.stringify` still emits them via `toJSON`. `addInput` / `addOutput`
+  drop a stale `link` / `links` key from `extra_info` instead of letting
+  `Object.assign` collide with the accessor — the store is not consulted
+  or mutated by such values.
+- **Duck-typed slots are upgraded in place.** `_setConcreteSlots` writes
+  the concrete `NodeInputSlot` / `NodeOutputSlot` wrappers back into
+  `node.inputs` / `node.outputs`. The concrete classes resolve their slot
+  index by identity (`inputs.indexOf(this)`), so a wrapper that is not
+  the array entry would permanently read as disconnected. Plain-object
+  slots pushed directly into the arrays are therefore upgraded at the
+  next concretisation (`configure`, paste/convert paths, every canvas
+  draw); until then their stale `link` value is dead data. Extensions
+  should use `node.addInput()` / `node.addOutput()` instead of pushing
+  literals.
+- **Serialized-data operators are untouched.** `linkFixer` (serialized
+  branch), `migrateReroute`, and `unpackSubgraph`'s pre-configure strip
+  operate on the wire format, which still carries `links`.
+- **Behavior changes, deliberate:** `PrimitiveNode.onLastDisconnect`
+  fires on disconnect-all (the stale mirror previously suppressed it);
+  `disconnectInput` passes `link_info.origin_slot` — not the old
+  mirror-array index — as the OUTPUT slot in `onConnectionsChange`;
+  serialization emits `null` where a lingering `[]` used to persist.
+
+Extension migration map: presence → `node.isOutputConnected(slot)` /
+`slot.isConnected`; enumerate targets → `node.getOutputNodes(slot)`;
+mutate → `node.connect(...)` / `node.disconnectOutput(slot, target?)`.
+App/Vue code uses `useLinkStore().getOutputSlotLinks(...)` (reactive).
+
+## Decision 5: Wire connected state into the dots (the payoff)
+
+`NodeSlots.vue` passes `connected` to each slot:
+
+- input: `linkStore.isInputSlotConnected(rootGraphId, nodeId, index)`
+  (already available)
+- output: `linkStore.isOutputSlotConnected(rootGraphId, nodeId, index)`
+  (Decision 3)
+
+`InputSlot` and `OutputSlot` already forward `connected` to the
+`lg-slot--connected` class. `SlotConnectionDot` needs no prop of its own:
+the wrapper class is an ancestor styling hook
+(`.lg-slot--connected .slot-dot`), so the visual is one CSS rule away once
+the design-standards check (open question 3) picks it. Threading a
+`connected` prop into the dot before that would be plumbing with no
+consumer. `compatible` stays driven by the existing drag state
+(`useSlotLinkDragUIState`), which this phase leaves alone.
+
+## Scope
+
+In scope: the derived output-side index, the two queries, the output-dot
+reader migration, and wiring `connected` from `NodeSlots` into
+`InputSlot` / `OutputSlot` (whose `lg-slot--connected` class reaches the
+dot via CSS).
+
+Since implemented by Decision 6: `output.links` reader migration, write
+sites, and field deletion.
+
+Out of scope, each a piece of the deferred `SlotConnection` phase:
+
+- Slot entity extraction: `SlotIdentity`, `SlotVisual`, and retiring the
+  `NodeInputSlot` / `NodeOutputSlot` class instances and their
+  `shallowReactive` graft.
+- A `compatible`-state source beyond the current drag UI state.
+- Floating/regular link-id counter unification (mint floating ids from
+  the shared `state.lastLinkId`) — only if the internal wart ever bites;
+  nothing resolves store-returned ids against `graph.links` across the
+  id spaces anymore.
+
+## Open questions
+
+1. **Index granularity.** One `computed` per graph rebuilds the whole
+   origin index on any link change in that graph, the same cost model as
+   `rerouteStore`. If profiling on large graphs shows this is hot, the
+   fallback is an incrementally maintained `Map` updated in `place` and
+   `displace`, which is more code and carries drift risk. Start with the
+   derived version and measure before optimizing.
+2. **Return type of `getOutputSlotLinks`.** Resolved: a set of
+   `LinkTopology`, per Decision 3. Bare ids looked sufficient until the
+   reader migration surfaced both the endpoint needs (minimap, widget
+   value propagation) and the floating-id collision hazard.
+3. **Dot visual.** What "connected" looks like on the dot (fill, ring, or
+   opacity) is a design-standards question rather than an architecture
+   one. Check the Comfy Design Standards before implementing Decision 5.

 ### The Scattered Access Problem
 
 This composable is called at **module scope** in domain objects:
 
-- `LLink.ts:24` — `const layoutMutations = useLayoutMutations()`
-- `Reroute.ts` — same pattern
+- `Reroute.ts:31` — `const layoutMutations = useLayoutMutations()`
 - `LGraphNode.ts` — imported and called in methods
+- `LLink.ts` no longer uses `useLayoutMutations` (its layout writes went away
+  with the `ylinks` mirror), but it still imports `layoutStore` and
+  `useLinkStore` at module scope
 
 These module-scope calls create implicit dependencies on the Vue runtime and make the domain objects untestable without a full app context.

+# Reroute Chain Store
+
+Date: 2026-07-04
+Status: Accepted (design review; follow-up to the
+[link topology store](link-topology-store.md), PR #13436)
+
+Design record for extracting reroute connectivity state into a dedicated
+store per [ADR 0008](../adr/0008-entity-component-system.md). Amends the
+`RerouteLinks` component described there.
+
+## Decision 1: The chain is the single source of truth for membership
+
+"Which links pass through reroute R" is encoded twice today: each link's
+`parentId` chain (`link.parentId` names the terminal reroute;
+`reroute.parentId` walks upstream), and per-reroute `linkIds` /
+`floatingLinkIds` Sets maintained by hand at roughly ten write sites
+(`LGraphNode.connect`, `LLink.disconnect`, `LGraph.addFloatingLink` /
+`removeFloatingLink` / `createReroute`, subgraph unpack,
+`SubgraphInput/Output.connect`, `LinkConnector`), with
+`Reroute.validateLinks` repairing drift at configure time.
+
+The chain is primary. Membership becomes a derived reverse index:
+
+```
+linksThrough(R) = { L : R ∈ chain(L.parentId) }
+```
+
+computed over the link store's topologies plus the reroute chain states,
+cached, and invalidated on chain mutation. The `Reroute` class exposes
+`linkIds` / `floatingLinkIds` as derived accessors. The membership write
+sites and `validateLinks` are deleted.
+
+Rejected: storing membership Sets in the store (the `LLink._state`
+pattern applied to whole membership). It keeps one _stored_ copy but
+preserves the domain-level redundancy — chain and membership can still
+disagree, and every dual write site survives.
+
+## Decision 2: Store shape and keying
+
+`rerouteStore` holds per-reroute chain state objects, registered by
+reference (the class reads through them, mirroring `LLink._state`):
+
+```
+RerouteChain { id, parentId?, floating? }
+```
+
+Buckets are root-graph-scoped (`rootGraph.id`), keyed by `RerouteId`,
+matching `widgetValueStore` and `linkStore` scoping. Owning-graph buckets
+were evaluated and rejected for the link store (2026-07-04) and are
+rejected here for the same reasons.
+
+`RerouteId` is the domain key because runtime allocation is already
+per-root-unique: `Subgraph.state` delegates to the root graph's state, so
+all graphs increment one shared `lastRerouteId` counter.
+
+## Decision 3: Load-time reroute-id dedup
+
+Serialized workflows from older frontends or external tools can carry
+colliding reroute ids across sibling subgraph definitions. Today this is
+tolerated only because `graph.reroutes` is a per-graph map; a root-scoped
+bucket would break on it, and the layout store's bare-`rerouteId` keying
+already collides latently.
+
+On configure, colliding subgraph reroute ids are rewritten to fresh ids
+from the shared counter, patching that subgraph's `link.parentId` and
+`reroute.parentId` references — the same repair the node-id and link-id
+dedup passes already perform. Rewritten ids serialize back changed.
+
+Rejected: a first-wins registration protocol (losers detached via an
+ownership flag). That is the apparatus the target-keyed link store
+redesign existed to delete.
+
+## Decision 4: Registration returns the reactive proxy
+
+The derived membership index requires observable chain mutation.
+`BaseWidget` already establishes the pattern: the store bucket is a
+`reactive(Map)`, registration inserts the raw state and returns the
+value read back from the map — the reactive proxy — and the class holds
+that proxy as `_state` (`BaseWidget.setNodeId`,
+`widgetValueStore.registerWidget`). Every subsequent class write goes
+through the proxy and is tracked.
+
+`rerouteStore.registerReroute` follows this: it returns the proxy and
+the `Reroute` class reads and writes chain state through it, so
+`reroute.parentId` mutations are tracked with no action chokepoint.
+
+`LLink` previously deviated — `registerLinkTopology` left `link._state`
+raw, which is why `linkStore.updateEndpoint` must re-wrap with
+`reactive()` before patching, and why bare `link.parentId` writes were
+invisible to effects. This migration aligns it with the `BaseWidget`
+pattern: link registration re-assigns `_state` to the store proxy,
+making `link.parentId` writes tracked. `updateEndpoint` keeps its
+`reactive()` wrap as a guard — the store is public API and may be
+handed a raw topology object.
+
+## Decision 5: Serialization
+
+`SerialisableReroute.linkIds` remains in the wire format, emitted from
+the derived membership in ascending link-id order. All runtime producers
+append links in ascending id order and the serialization goldens hold
+ascending arrays, so chain-consistent workflows round-trip byte-identical.
+
+Workflows whose stored `linkIds` contradict their chains are repaired on
+the next save (membership re-derived, stale ids dropped, order
+normalized). A reroute that no chain reaches at all is dropped at load —
+where `validateLinks` used to preserve it if its stored ids named live
+links — because the chain is primary. No compatibility shim for such
+files. `floatingLinkIds` stays unserialized, rebuilt at runtime as
+before.
+
+## Scope
+
+This design covers chain state, derived membership, and the `LLink`
+proxy retrofit from Decision 4 (a small self-contained change, done
+first). Reroute visual state (`_colour`, badge) is out of scope. The
+`Reroute.pos` class field still mirrors the layout store's position;
+that pre-existing duplication is a separate concern, not addressed
+here.
