docs/CLAUDE.md Phase 1 output, after the reorganisation.
- docs/README.md: rewritten as the map -- where each kind of document
lives, which one to believe (CLAUDE.md, FABRIC, v4.0.0, reference/,
BRINGUP, code), how to retire a document.
- docs/INDEX.md: regenerated from the tracked tree, 489 rows, every
document with a status (the 2026-06-16 snapshot was stale).
- docs/DEAD-AND-REVISED.md (new): what was abandoned (L4Re, the hal_*
contract, ACL RWT, the Hermes VM, elevation, the knowledge factor, ...)
and what was corrected (ACL overhead, versions, block rules, parity
baseline, ...), each with its date and record.
- docs/DELETE-CANDIDATES.md: 12 duplicates, awaiting a ruling; nothing
deleted.
- CLAUDE.md: versions corrected (3.2.0 / 2.1.0).

boards/BRINGUP.md A3 and S3, FABRIC-3 SXLI. A HID boot keyboard is
configured (interrupt IN endpoint, SET_PROTOCOL boot) and its reports
become the same Linux-keycode events as PS/2 and virtio (usb_kbd.c): the
full layout -- F-keys, navigation block, arrows, Num Lock, keypad. The
console treats Caps and Num Lock as toggles shown on the keyboard's
lights, and the keypad as digits or navigation. While a USB keyboard
runs, its event ring is serviced every tick, not once a second.
Found on the way: with no i8042 (port 0x64 reads 0xFF) the kernel hung at
boot in an endless drain -- a legacy-free PC would stop there. Detected
and skipped now; drains bounded.
QEMU, amd64 with the USB keyboard the only one: 1 2 + . on main keys and
keypad, Caps Lock, Num Lock all right; aarch64/riscv64 configure it too.
Acceptance on three ISAs unchanged; identities hot-plug.

FABRIC-3 SXXXII.4's deferred LOG-FLUSH, built to the 2026-10-14 rulings
(SXXXVIII): everything a VM logs, at or above the log level, goes into its
own buffer; it goes to Artemis on LOG-FLUSH, when full, and at once on an
ERROR, as one kernel-Hermes LOG_BATCH message she writes on her own turn,
the source being the sender the kernel stamped. Records that cannot go yet
are counted and reported with the next flush. LOG-SHOW (Hera only) reads
the ring back -- it had no reader.
Found by the first test that filled it: ring growth overwrote the oldest
record and put blank slots inside the live range. Fixed test first.
Three ISAs: POST 1052 passed; new parity baseline word_count=526
hash=0x82f4ae7cb2e2d424 (deliberate). CLAUDE.md: Phase 8 PKI closed.

FABRIC-3.md XXXIV.1, traced and fixed. vm_interpret() copied each text
into the VM's one input buffer and reset the position. LOAD runs its
block by calling it, so the block replaced the line LOAD was on and
nothing after LOAD or THRU on that line was ever interpreted; the same
for -->, a capsule's EXEC and a message kernel-Hermes delivers.
vm_interpret() now keeps what the outer text had not yet read when it is
called from inside another, and puts it back after, as FORTH-79's LOAD
keeps the input stream it interrupts. In the kernel's VM and the hosted
one alike.
POST: LOAD.rest_of_line (1 LOAD 0 0 /) and THRU.rest_of_line
(1 2 THRU 0 0 /) failed without the fix (logs/20261014-061222) and pass
with it. Three-ISA acceptance: logs/20261014-061508 (amd64), -061624
(aarch64), -061837 (riscv64), 1052 tests, none failed, zuse prompt,
hash 0x08873e0f44b7cb2a unchanged. The hosted binary: 100 LOAD 1 + .
gives 8.

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
