Tier 1 — violates CLAUDE.md rule 4 ("wire helpers must be pub(crate)"); freezes byte offsets as public API.
Evidence
lib.rs pub mod wire; exposes encode_frame, decode_frame, FrameHeader, FrameOffsets, EncodedFrame, DecodedFrame, WireError, DecodeError, PAYLOAD_ALIGN, HEADER_FIXED_SIZE, and all *_OFFSET consts.- A 2nd adapter only ever needs
encode_frame/decode_frame + the error types (fjall uses exactly those).
Risk after freeze
Downstream code can hard-depend on GLOBAL_SEQ_OFFSET == 0, HEADER_FIXED_SIZE == 18, FrameHeader's field set — freezing the on-disk offsets as public commitments.
Action
Curate wire to a minimal public surface: encode_frame, decode_frame, EncodedFrame, DecodedFrame, FrameOffsets, WireError, DecodeError, PAYLOAD_ALIGN. Demote the *_OFFSET consts, HEADER_FIXED_SIZE, and FrameHeader internals to pub(crate). (Pairs with the T0 frame-version issue.)
From the freeze-readiness audit (store I7 + adapter C2).
