Punch list §25 item 4.3.5a complete.
Firmware (EDK2 RISC-V) leaves Sv57 paging active at kernel entry with an
identity mapping that has at least one confirmed hole (PLIC threshold
register). Verified live before acting: satp.MODE/PPN and __kernel_start's
address confirmed identity mapping; switched to Bare mode (csrw satp, x0 +
sfence.vma) in arch_early_init(), ahead of pmm_init()/vmm_init().
Three-arch acceptance boot clean, zero exceptions; riscv64's PLIC_THRESHOLD
write now survives (PLIC driver code itself lands separately with 4.3.5b).

Three-arch acceptance run (amd64/aarch64/riscv64) after adding -device
ramfb to aarch64/riscv64, plus the interactive GOP-verification and cube
sessions on both.
Three-arch acceptance run (amd64/aarch64/riscv64) plus the interactive
sessions used to test LINE/CIRCLE/ARC/ELLIPSE, the block-span test, and
verify the Q.TO-INT fix.
Three-arch acceptance run (amd64/aarch64/riscv64) plus the interactive
fabric.4th verification sessions used to test CART-PLOT and find the
VARIABLE alignment bug.
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.

Punch list §25 item 0.1 complete.
Verified: all three architectures build clean and boot to the ok> prompt with
Hera alone. Blocks executed are exactly 2057 -> 2049 (-> lib.4th/4050) -> 2050.
Zero occurrences of "Hermes" or "Tripod" in any of the three serial logs, and
the only parity record is MAMA_INIT -- no baby VM is born. mkcapsule --lint
passes 26 files, 0 failing, 0 violations.
Deleted blocks 2051, 2052, 2053, 2054, 2055, 2056, 2058, 2059 -- readiness
handshake, broadcast test, TRIPOD-TEST, HERMES-E2E and the fleet-DoE
scaffolding. Edited 2057 (banner), 2049 (dropped both births with their
CD-INIT calls and the common:msg.4th / process.4th loads, which are wholly
Hermes-dependent; kept lib.4th; VM-TREE and VM-CHILDREN no longer name absent
children) and 2050 (kept the BOOT-BANNER call, dropped the two calls to the
deleted words). capsules/hermes/ and capsules/artemis/ untouched on disk.
New Hera-alone parity baseline, identical across all three ISAs:
dict_hash=0x3d4e1daf289da94f capsule_hash=0xb4c4b5559146a3bd
This supersedes the pre-prune baselines in logs/ and is what item 0.10's
double-boot reproducibility check compares against.
Commit contents beyond the item's own edit, noted rather than slipped in:
capsules/BLOCK_MAP.md is regenerated by any build; the three serial logs are
this item's acceptance evidence and CLAUDE.md requires committing them; the
DoE CSVs are auto-extracted by the qemu target on every run. Leaving generated
output from this item's acceptance run for a later item to sweep up would be
worse than including it here.
Reported, not fixed: tools/mkcapsule.c emits two -Wstringop-truncation warnings
on the host build (:404, :562), pre-existing.

The generic block subsystem (blk_format_or_load_disk) auto-reformatted
any disk lacking its own low-level 'STFR' header at attach time, before
Artemis's Forth-level BLANK/LithosAnanke/Unrecognized classification
ever ran -- so ART-HALT-UNRECOG's "Disk preserved" message was false.
Split detection from commit: an unrecognized/blank disk is now left
PROVISIONAL (geometry computed in memory only, all writes refused)
until explicitly confirmed via the new blk_subsys_confirm_format() /
BLK-CONFIRM-FORMAT primitive. Artemis calls it from ART-FORMAT and
ART-RESUME, never from ART-HALT-UNRECOG.
Verified on amd64/aarch64/riscv64: parity intact (identical dict_hash),
normal recognized-disk resume + persist-read unaffected, and a
regenerated disk/artemis-unrecognized-test.img (the old copy had itself
been silently corrupted by this exact bug) now stays byte-for-byte
identical across a halted boot on amd64 and riscv64.
