Module reference 

Catalog lookup accepts aliases and source URIs without dropping source identity.

Functions

display_source 🔒

Choose a concise source locator, keeping revision detail for disambiguation.

find 🔒

Lookup may report absence so the resolver can register explicit sources. Store-qualified references inspect catalog metadata, not live store contents.

is_revision 🔒

Immutable revision prefixes use at least eight hexadecimal digits.

lookup 🔒

Resolve exactly one catalog entry; never fall back from an ambiguous source.

matches_selector 🔒

Match an exact source namespace and optional immutable revision prefix.

preferred 🔒

Prefer an alias or unqualified source URI; add revision detail only when needed.

selects 🔒

Confirm that a display selector returns this entry, including alias precedence.
