The legacy rio v1 stream format authenticates only each frame's ciphertext: the 8-byte header (length + plaintext CRC32) and the end marker sit outside the AEAD, frames carry no position binding, and nothing marks the last frame - header rewrites, frame reordering and truncation of trailing frames are not cryptographically detected. Add a v2 layout in the same format family, dispatched per frame by the type byte: - the header plus the frame's index are AEAD associated data (0x01), so header tampering, reordering and cross-position splicing fail authentication; - the final frame carries its own authenticated type byte (0x02); a clean EOF or an end marker before it is an error, every stream (including the empty one) ends in an authenticated final frame, and a v2 multipart stream fails if it ends before all listed part segments; - the writer accumulates full 8 KiB blocks, so non-final frames are fixed-length (8218 ciphertext bytes) and single-part objects gain a closed-form offset mapping for the follow-up range seek. Key hierarchy, nonce derivation, envelopes and metadata are unchanged; v1 objects stay readable forever, while v2 frames reject the historical nonce fallbacks and unknown frame types become a hard error. Write side ships off by default (RUSTFS_ENCRYPTION_FRAME_V2): mixed version clusters cannot read v2 frames, and encrypted ciphertext travels verbatim through transition, decommission and SSE-C replication passthrough. This release ships read support; the default flips in a following release.
