verify the Q.TO-INT fix.

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.

Chases down the amd64/aarch64/riscv64 "FAIL: persist-read" that
capsules/artemis/init.4th's ART-READ-TEST self-test has been reporting
in every boot log in this repo's history.
Root cause: not a code bug. disk/artemis.img had been stuck in a
corrupted state (valid LithosAnanke magic header, but data not matching
what ART-READ-TEST expects) since before this repo's own git history
begins -- already broken at the initial commit, carried over from the
pre-split monorepo. The FAIL was accurate: it correctly reported bad
data, not bad code.
Verified via a fresh disk/artemis-debug-roundtrip.img: format ->
self-test PASS -> write-test PASS -> reboot -> resume -> PASS:
persist-read, confirmed 3 times in a row. The write/read/persist code,
free map, block allocator, and C-level block subsystem cache/writeback
logic are all correct.
Fix: blanked disk/artemis.img and let a normal boot format + write-test
it fresh, then verified PASS: persist-read on amd64, aarch64, AND
riscv64 against the same reformatted image -- confirming the arch-neutral
on-disk format works cross-arch too (a boot on one architecture writes
data the other two can correctly read back).
disk/artemis-debug-roundtrip.img is kept as a regression fixture, already
in a known-good passing state -- a future break here is a real
regression, not fixture rot like artemis.img turned out to be.
disk/README.md: documented both images' state, and corrected a stale
claim that these images are managed via scripts/rundisk.sh -- that
script actually targets a separate, currently-unused disks/ (plural)
directory for the hosted VM's --disk-img= flag, not this kernel-QEMU
disk/ (singular) one.
