idunn-rudp.cjs was 324 lines of which almost none were about Idunn. The
transport moved to CultLib as cultnet-ts's signed-daemon-health module, beside
the RUDP session it was already built on. What is left here is 65 lines: the
three constants naming Idunn's wire contract, and the call shapes Odin's
consumers already use.
The constants are declared, not decided. Idunn defines them in
docs/signed-daemon-health-authority.md, which until today did not state the
connection id at all -- the value describing how to reach Idunn existed only in
this consumer. Declaring two constants against a documented contract is not
duplicated authority; duplicating 311 lines of transport across Odin and a
future Hermodr repository would have been.
The module also stops resolving CultLib by walking up three directories from its
own location. It now honours CULTLIB_ROOT with that walk as a fallback, matching
what hermodr-daemon.cjs already did. The old assumption held only while Odin sat
beside CultLib, and Erycina broke on exactly that when it moved.
The signed-health test now supplies IDUNN_HEALTH_CONTRACT to the publisher it
builds by hand, and still asserts the literal wire values, so a change to the
contract constants fails loudly rather than being absorbed.
Verified: 22 tests pass across six files, including signature verification
against the relocated implementation, and the syntax check is clean.
