Modules

canonical

Canonicalisation of composition graphs.

deprecation

Deprecation-chain resolver.

resolver

Pinning resolution pass.

Structs

CompositionGraph

A complete composition graph with metadata.

Enums

CompositionNode

A composition graph node. The core AST for Noether’s composition language.

Pinning

How a Stage reference resolves to a concrete stage in the store.

PrefixResolutionError

Errors raised by resolve_stage_prefixes when an ID in the graph cannot be uniquely resolved against the store.

Functions

collect_stage_ids

Collect all StageIds referenced in a composition node.

compute_composition_id

Compute a deterministic composition ID.

parse_graph

Parse a Lagrange JSON string into a CompositionGraph.

resolve_stage_prefixes

Walk a composition graph and replace any stage IDs that are unique prefixes — or human-authored names — of a real stage in the store with their full 64-character IDs.

resolve_stage_ref

Resolve a CompositionNode::Stage reference to a concrete stage in the store, respecting the node’s pinning.

serialize_graph

Serialize a CompositionGraph to pretty-printed JSON.
