Every AssetNode is assigned an AssetType during the Loading build report phase by BuildReportAdapter's private ClassifyType() method. Classification is by Unity runtime type name only — there is no file-extension fallback. If the runtime type is null, or its name doesn't match a known type, or it's some other unmatched type, the asset is classified as Other.
ScriptableObject is the one exception that isn't a flat name match: ClassifyType() walks the type's base-class chain looking for ScriptableObject, so any subclass — including types BuildLens has never heard of — is correctly classified, not dumped into Other.

This list is intentionally short. If you're seeing assets you'd expect to be more
specifically classified land in Other, that's almost certainly why — there's no
secondary classification pass to catch them.
Unity packs shader variants as separate BuildReport entries. Each variant is an individual AssetNode with Type = Shader. The treemap shows every variant as a separate rectangle. The total size contribution of a shader in the filter is the sum of all its variant entries.
Shader variant keyword analysis is not currently available.
TMP_FontAsset does not match the Font type name check — it's matched on the exact
string "Font", and TMP_FontAsset doesn't match that. Since TMP_FontAsset is itself a
ScriptableObject subclass, it falls through to the ScriptableObject classification
instead. If you're tracking font atlas size, look for it under ScriptableObject, not
Font.
Other has its own chip in the filter bar, the same as every other type — there is no special-cased exemption. Unchecking it hides Other assets from the treemap and asset list exactly like any other category, though they still count toward the summary bar's totals and participate fully in the dependency graph.
