Render parsed source identifiers back to their canonical SourceOp form before source policy evaluation. This lets Git subdir cleanup use the existing source parser and avoids policy-specific Git parsing. Add String methods for source identifiers and cover them with unit tests, plus a client integration regression for canonical Git subdir policy matching.
