The Rust runtime gains the reference's content chunk messages on the raw
path, CultMeshCdnArtifactManifest with wire-ordered metadata,
normalize_hash, pack_content, validate_manifest,
answer_content_chunk_request (every bad request is answered, byte
identical to the reference server) and fetch_content (one owner of
receiving-side verification; refuses zero-size floods and unnormalised
hashes before any request). Vectors run both ways between C# and Rust.
The operator ruled Q-BP1 A: chunks travel on the session already held.
This is the explicit Rust content path until an authenticated connector
exists.
Soul passed it after two fix batches. cultnet-rs: content 24, cultnet 53,
rudp 7, lib 110. cargo-mutants on content.rs misses 0.
