The dual-proved runtime presence contract existed only in cultnet-rs, so no
TypeScript service could make a statement Odin admits as presence. Odin files
anything else away as an ordinary document and never produces a topology
correlation for it, which is why Heimdall could warm forever without being
promoted.
The port is what it should be: the same fields at the same key slots. The Rust
derive serialises a positional tuple indexed by those slots, so the TypeScript
side names the slots and fills the same 24. Both proofs cover one payload --
the complete record with both signature fields empty -- and the two signing
messages use the domain separation their respective identities already define.
Conformance is against vectors emitted by cultnet-rs, not a fixture written
for both sides at once, which would agree with itself and prove nothing:
`cargo run --example runtime_presence_vector -p cultnet-rs` regenerates them.
