Module migration_inference 

Static analysis for automatic migration dependency inference.

Scans a migration body (raw SQL string) for collection references and returns which collection names it touches. The engine uses this to infer dependency edges between migrations that share a collection — without requiring the developer to write explicit DEPENDS ON.

Conservative by design: ambiguous references produce no inferred edge rather than a wrong one. The developer can always add an explicit DEPENDS ON to override.

Functions

infer_dependencies

Infer dependency edges for a new migration given existing migration metadata.

referenced_collections
