Migrates Hermes's message/channel lifecycle onto the Stadium's unified heat/capacity economy: MSG-ALLOC/FREE-NODE and CH-ALLOC/FREE-NODE now route entirely through stadium_admit()/stadium_evict(), replacing the old local free-list + independent heat-field mechanism. Eight kernel-only STADIUM-* FORTH primitives (ADMIT, EVICT, RES@, RES-PULL, RES-PUSH, HEAT@, HEAT!, WORD-HEAT), VM.stadium_vm_id threaded through all three vm_core.c dispatch sites (replacing item 4.1's hardcoded vm_uuid_hera()), and the stadium_owner[idx] fix so evict-credit lands in the VM that actually admitted a patron, not whoever owned cell 0. This session's own contribution, on top of that pre-existing implementation: found and fixed two bugs blocking the item's own K≡1.0 conservation self-check (HERMES-K was reading 0, not 65536): - Q.SLOT admission-heat fix (capsules/hermes/init.4th): MSG-SEND/ CH-ACCEPT admitted with Q.1 (the entire fleet-wide "1.0" unit) per item, a leftover from before the Stadium migration when each message/channel had its own unconstrained heat field. Instantly drained the shared, finite reservoir. - Reservoir floor for word-execution admission (stadium_words.c): stadium_word_dispatch() (item 4.1) pulls STADIUM_WORD_HEAT_QUANTUM on every word dispatch, not just first admission -- exhausts a VM's entire reservoir in ~32 dispatches, starving any application-level economy sharing that VM's reservoir before it gets a chance to pull anything. word_dispatch_pull() now clamps word-execution's own pulls to leave a Q48_ONE/3 floor (same fair-share figure COMMON-CH's own floor already uses); application-level pulls are unaffected. - STADIUM-WORD-HEAT primitive + stadium_words_resident_heat(): the floor deliberately leaves word-execution residents holding real heat, invisible to HERMES-K's original formula (MSG+CH+reservoir, no term for word patrons). Adding this term closes K to exactly 65536 on all three architectures. Also rules on two open scope questions in FABRIC.md: MBR-ALLOC/ MBR-FREE-NODE stay off the Stadium (membership records have no heat field, never did -- the acceptance bullet's inclusion of them was a completeness gesture predating a check of the actual layout), and records the effort number (12 implementation files, +759/-120 lines). Verified: all three architectures boot clean, full self-test passes, Stadium conservation closes exactly (resident_sum + reservoir = Q48_ONE) at both the C/Stadium level and the FORTH-level HERMES-K check.

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.
