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.

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.

FABRIC-3.5 SXXXII, closing FABRIC-3 SXXIX bug 2 (SXXXVI). A send marks the
receiver for the switch signal; the VM's own loop on its native stack takes
its messages and yields; Hera's idle beat makes the pending switch instead
of running other VMs' messages on her stack; every VM gets switcher turns
from birth; the drain refuses any call outside the VM's own context (the
test: it held every relayed line before, none now).
Found on the way: amd64's first-entry frame left rsp 8 bytes off the SysV
entry alignment (#GP on the first interpreter run on a VM's own stack), and
a VM yielding from its loop was marked SWITCHED_OUT, which stopped console
relay after one message and would have made KILL refuse it.
Relay of four lines to a WIREBIND identity on all three ISAs, five
hot-plugged identities, and standard acceptance (POST 1052, hash
0x08873e0f44b7cb2a) all pass.

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
