-`ExtensionManifest.iter_contributions()` yields dicts of the form `{layer, sourceId, kind, name, id, ...author-declared fields}`; each entry's `id` is the computed identifier. `ExtensionManifest.contribution_id(kind, name)` returns the id for a single lookup, or `None` if no contribution matches. `PresetManifest` exposes the same two methods.
+`ExtensionManifest.iter_contributions()` yields dicts of the form `{layer, sourceId, kind, name, id, ...author-declared fields}`; each entry's `id` is the computed identifier. `ExtensionManifest.contribution_id(kind, name)` returns the id for a single lookup, or `None` if no contribution matches. For hooks whose compound name matches multiple discriminated entries, it raises `ValueError`; callers must use `iter_contributions()` to select the desired full id. `PresetManifest` exposes the same two methods.
 
 `PresetResolver.collect_all_layers()` returns layer dicts that include a `lookupId` field for every layer type (`project override`, convention-discovered preset, convention-discovered extension, manifest-backed preset, manifest-backed extension, core, and bundled core).
