Two independent defects kept them unreadable, both reached only once the fixture harness could load an inlined object at all. The stream was keyed as if the object were multipart. is_multipart_encrypted_object falls back to an ETag length test when there is a single part, and MinIO stores an *encrypted* ETag for SSE objects — 96 characters for a single-part upload, not the 32 of a plain MD5 — so every such object read as multipart and had a per-part key derived for a stream sealed with the object key itself. MinIO records the answer outright in X-Minio-Internal-Encrypted-Multipart, so that marker is now consulted first, and on a MinIO-written object its absence is treated as just as informative as its presence. The size was then reported as the ciphertext's. MinIO writes an explicit plaintext size only for multipart uploads, deriving it from the DARE stream otherwise, so both the read plan and ObjectInfo::decrypted_size fell back to the physical size — the reader waited for the encoding overhead as if it were payload, and a client would have seen a Content-Length overstated by exactly that much. dare_v2_decrypted_size inverts the package layout the way MinIO's sio.DecryptedSize does. It lives in rustfs-utils so the read plan and the size accessor cannot drift apart, and it returns None for a length no DARE stream can have rather than assigning a malformed object a plausible one. The interop suite is 9/9 with the two single-part cases added, and reverting the classification to the ETag heuristic turns both red. rustfs-ecstore's object_api tests and rustfs-utils are unaffected.
