Rewrote EXEC-STD79-DOE-CD's dispatch to coordinate via MSG-SEND/ MSG-TICK instead of blocking VM-EXEC, now that Hera can genuinely message (§XX). RUN-TEST/EXEC-STD79-DOE (the serialized baseline) are untouched, kept as a byte-for-byte-reproducible historical comparison point. A small 2-identity smoke test before any multi-architecture commitment caught two real defects the design alone didn't predict: 1. Absolute VM-HEAT can't produce fine-grained interleaving -- a fresh identity starts at heat=0 against Hera's ~62000+, a gap no 1..24 divisor closes, so priority locked onto whichever identity had executed least, for its entire campaign. Fixed with BASE-HEAT: each identity's heat is snapshotted once at campaign start, and priority is computed from heat gained *this campaign*, not lifetime heat. 2. Single-test-per-message granularity silently drops most of a campaign's data: MSG-SEND no-ops on MSG-ALLOC failure, and the turn bookkeeping advanced regardless, so rows looked complete while missing most of their tests. A live reservoir probe showed Hera's own STADIUM-RES@ draining ~725/cycle with no replenishment observed -- a 648-send full campaign would exhaust it almost immediately. Fixed by dispatching a whole rep (24 tests, one concatenated command, measured 442 bytes, well under VM-EXEC's 1025-byte cap) per message instead -- 27 sends for a full campaign, not 648. Re-verified after both fixes: 99/99 expected test outputs present, zero drops, zero faults, genuine rep-level interleaving instead of either the serialized baseline's fixed order or the first cut's 72-test lock-in.

FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.
