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.

The flat-pool storage scope ("Immediate Goal") has been implemented for
some time -- capsules/artemis/init.4th boots live in the Tripod fleet on
every kernel boot -- but the doc still said "do not begin implementation
without explicit instruction from Captain Bob" in two places, and
CLAUDE.md's pointer still said "build-authorization deferred."
.claude/ARTEMIS.md: replaced both stale lines with a dated Build Status
section giving an honest per-criterion accounting rather than a blanket
"done": 4 of 6 acceptance criteria fully confirmed (boot-state detection,
free-map init, fetch/persist, and -- as of the persist-read fix earlier
today -- cross-boot/cross-arch persistence), K-conservation implemented
but not hard-asserted, and the unrecognized-disk halt implemented but
never actually exercised against real unrecognized content. Future
material (zones, USB hot-plug, ACL records, PKI) remains correctly
marked deferred -- unchanged.
.claude/CLAUDE.md: updated the Artemis pointer line so it's consistent
with the above instead of contradicting it.
