The previous commit cleared source provenance from every served record.
Odin's snapshot source serves runtime-presence records with provenance it
authors itself (source_runtime_id, source_agent_id, source_role and an
odin-observed tag), and a crate test pins that a raw response is served as
the source returned it. The server does not own that shape, so it no
longer rewrites it, and admission again sizes the record as received.
Which rule a Rust server should size by is reported as a fork.
The fragment-count admission, the construction cross-check and the
exact payload-budget fixture stand. The budget fixture's put carries a
longer message id so its frame, the exact budget, is at least its
served-alone response. Polling for a refusal sleeps when the server is
idle, so a put of many fragments has time to arrive.
