Module schema_cache 

Data-source schema cache backed by unified shape.lock artifacts.

This replaces the legacy shape.database.lock.json sidecar file and keeps external schema state in the shared lockfile model.

Structs

DataSourceSchemaCache

Top-level cache model for external data-source schemas.

EntitySchema

Schema for a single data-source entity.

FieldSchema

Schema for a single field.

SchemaCacheDiagnostic

Diagnostic emitted while loading schema artifacts from shape.lock.

SourceSchema

Schema for a single data-source URI.

Constants

CACHE_FILENAME

Top-level cache file path. Kept for call-site compatibility.

load_cached_source_for_uri

load_cached_source_for_uri_with_diagnostics

Load one cached source schema by URI and keep non-fatal diagnostics for stale/invalid artifacts that were ignored.

load_cached_type_schemas_for_uri_prefixes

Load cached schemas and convert matching sources into runtime TypeSchemas.

load_cached_type_schemas_for_uri_prefixes_with_diagnostics

Like load_cached_type_schemas_for_uri_prefixes but also returns non-fatal diagnostics for invalid/stale artifacts that were ignored.

set_default_cache_path

Override the default lock/cache path used by extension-side schema cache helpers during this process.
