Interface: PredecessorOutputs

Defined in: packages/core/src/graph/types.ts:125

The union of predecessor outputs fed into a node's combine function. The shape carries BOTH id-keyed and label-keyed views so custom combines can choose the one that fits — id is stable across renames, label is stable across refactors within a graph. order is the topologically-sorted list of predecessor node ids, useful for fold-style combines.

sourceRowId is the provenance tag the default combine aligns on. Custom combines that change cardinality (join, aggregate) are responsible for emitting a NEW sourceRowId for their output rows.

Properties​

byId​

byId: Record<string, unknown>

Defined in: packages/core/src/graph/types.ts:127

Output keyed by predecessor node id (stable).

byLabel​

byLabel: Record<string, unknown>

Defined in: packages/core/src/graph/types.ts:129

Output keyed by predecessor node label (ergonomic in prompts).

order​

order: string[]

Defined in: packages/core/src/graph/types.ts:131

Predecessor node ids in topological position.

sourceRowId​

sourceRowId: string

Defined in: packages/core/src/graph/types.ts:133

Provenance tag for this execution. See Provenance Invariant.
