+**The Rust alias port landed** (Sonnet). Rust's `schema_alias::matches` is
+now `(candidate, schema_id, schema_name)`, and it matches the C# reference row
+for row: exact id, bare name, `.vN` on the name, case-sensitive, the last

+produced by running the reference source. The hash-stripping overload is
+deleted. `SchemaVersion` and `CompatibleSchemaIds` are not ported, because no
+Rust call site needs them; that is a stated reduction. Rust entries are 40/40
+killed. The whole suite had never run under `-Repo` before, and its commands
+now carry `--manifest-path`.
