check / check (push) Failing after 2m22s
atime left mf.proto earlier and nothing reads or writes it, but docs/FORMAT.md still narrated its removal and listed it among the determinism rules. The spec now describes the file entry by its fields only. A new test compares the MFFilePath message descriptor, by name and number, with a list copied from the spec's field table. It does not read the spec, so changing a field means changing the proto, the spec and that list together. Model: opus-5-5
