The FusionVault contract: ontology schemas, cross-language conformance vectors, and generated catalogues — self-contained typed bindings for TypeScript.

The FusionVault value-expression language for TypeScript: parse, validate and evaluate the expressions pipelines and filters use, with the function catalogue from the published contract.

Load and validate FusionVault ontology definitions against the contract's meta-schemas, compile them into a manifest, and validate instance values including GeoJSON geometry.

The FusionVault merge: fold property-level edits into an object in a deterministic order, with conflict detection, matching the Rust engine bit for bit.

The pure core of FusionVault transformation pipelines: definition types, the publish gate, the step-kind registry, DAG ordering, column-level lineage and the expectation evaluator. No I/O.

Typed predicate DSL to OpenSearch query DSL, and the declarative label-policy filter builder. Pure functions; no client.
