Module federation 

Application-only reference namespaces preserve the engine’s original identities.

Enums

Source

An explicit catalog owner; remote and local identities never collide.

Functions

map

Rewrite schema identity slots only; notes, tags, filenames and source claims remain exact.

qualify

Qualify only an engine identity, preserving its entity kind.

request_origin

Resolve and unwrap known request selectors before choosing a native client. Track lyrics use track, while ordinary catalog routes use ref/reference.

resolve

Unwrap an application identity. Legacy raw references belong to the remote server. Only a marker immediately after the entity kind is structural; keys remain literal.
