Not yet accepted (plan 2026-10-29-stick-5, Task 2, step 3).
- gpt.c: the writer, gpt_grow_last() -- the backup entry array and header to
the disk's end, the last partition to the last usable sector (whole MiB,
capped), both headers' CRCs, the backup before the primary, the
protective MBR's size; gpt_alternate_lba().
- sk_v4_grow.c: the volume grown to its partition -- its fence (the Artemis
signature, Zuse's genesis marker) moved to the new top, the header last;
the partition grown no further than the BAM tracks (the block subsystem
places the fence by the device's size, so a volume must fill it).
- sk_v4_identity.c: a stick of 8 GB or more whose GPT ends short of the disk
is grown before its partitions are opened; "Artemis: grown to fill the
stick" / "under 8 GB -- not grown" / "past 256 GiB ... left unused".
- block_subsystem: blk_volume_compute_totals() (compute_totals_from_B,
public) and blk_subsys_set_format_bam_for(); v3's behaviour unchanged.
- mkartemis --bam-for, mkdiskimage.sh --bam-for, kernel/Makefile
STICK_GROW_MIN_BYTES / STICK_ARTEMIS_CAP_GIB: the stick's and data stick's
Artemis BAM sized for 256 GiB (6144 devblocks). STICK.md 5a: 256 GiB (R1).
After: stick_grow PASS (16 GiB: 12129370 user blocks, 8 s POST to prompt;
second boot not grown, recognised; sfdisk --verify: no errors), stick_small
PASS, check_images.sh PASS.

Any identity could have arbitrary FORTH run as Zuse: KH-ELEVATE-SEND and
KH-BLK-ATTACH-SEND sent any text to Hera, from any VM (shown live). And the
drain popped a message after running it, so a payload calling a colon word
ran twice. Both fixed test first (FABRIC-3 SXXXVII):
- KH-BLK-ATTACH-SEND is ( dev-addr ok? -- sent? ), Artemis only; the kernel
writes the reply text. BLK-ATTACH-ACK is Hera's only.
- The drain pops before it runs.
- Elevation, ruled not needed: KH-ELEVATE-SEND, message type 8,
zuse-eligibility.4th, ZUSE-ELIGIBLE?/ZUSE-ELIGIBILITY-ADD/
ELEVATE-PUBKEY-UNPACK and the eligibility list removed; its disk area
stays reserved, unused. FABRIC-3.7 closed.
Three ISAs: POST 1052 passed; new parity baseline word_count=523
hash=0xb73b58052d591638 (deliberate).

blk_chain_default, blk_chain_new and blk_chain_select (0e761cb1) were for
a node's own drive, which was withdrawn on 2026-10-07 (docs/v4.0.0/MESH.md
8.5). They are taken out. What remains of that change is that
blk_subsys_init takes no VM.
Accepted on the v3 configuration: amd64, aarch64 and riscv64 reach the
zuse prompt, no UNKNOWN WORD, PARITY:M7.1a hash 0x08873e0f44b7cb2a on all
three, as before. logs/20261007-082647, -082752, -082938.

The global state becomes struct blk_chain, reached through a current
pointer: blk_chain_default, blk_chain_new, blk_chain_select. Nothing
that uses the one chain changes. blk_subsys_init loses its VM argument,
which was stored and never used. docs/v4.0.0/MESH.md 8.4.
Accepted on the v3 configuration: amd64, aarch64 and riscv64 reach the
zuse prompt, no UNKNOWN WORD, PARITY:M7.1a hash 0x08873e0f44b7cb2a on
all three, as on 2026-10-03. logs/20261006-202918, -203036, -203230.

Source tree reorganization:
- Move StarForth v3 engine to v3/ (src/, include/, Makefile)
- Move kernel to kernel/ (src/, include/, linker/, Makefile)
- Create v4/ skeleton for F18-ISA golden model (DECOMPOSITION.md, JUSTIFICATION.md)
- Move FABRIC-0..4.md to docs/fabric/
- Move ONTOLOGY.md and ROADMAP.md to docs/
Board infrastructure:
- Add boards/ser5/, boards/raspi/, boards/milkv/, boards/zynq7020/
- Each board has board.mk (ISA, CPU flags, boot recipe) and README.md
- Root Makefile becomes thin dispatcher: boot_image, all, clean, docs take TARGET
- make boot_image TARGET=SER5|RASPI|MILKV builds one GPT/MBR image per board
- ZYNQ7020 target exists but stops with clear error (ARMv7 port not built yet)
- scripts/mkdiskimage.sh builds disk images for all boards
Docs pipeline:
- docs/book/ with LaTeX master (main.tex) and Makefile
- pandoc converts Markdown to LaTeX at build time
- Two Lua filters: table-widths.lua (wide tables wrap), code-breaks.lua (inline code breaks)
- make docs builds single PDF (754 pages, 0 missing characters)
- make docs TARGET=<board> adds board appendix
- build/docs/<book|board>/meta.tex stamps git commit into PDF
Bug fixes:
- 42 include paths that only worked by accident now use correct relative paths
- clang-18 hardcode replaced with configurable CC variable (fixed aarch64 build)
- Pi 5: kernel_2712.img linked at 0x80000, .bss zeroed, memory reserved
- Doxyfile, .clang-tidy, README.md, Kconfig paths updated
Verified:
- Hosted v3 build passes 1012 tests, 0 failures
- SER5 image boots in QEMU (OVMF), POST passes, K exact (65536 = Q48_ONE)
- Milk-V image boots in QEMU (OpenSBI + U-Boot + bootefi), POST passes
- make clean TARGET=<board> removes only that board and its ISA objects
- make all builds all boards, hosted v3, and docs in one run
