rajamesandJunie a8b70e88d3 Reorganize source tree: kernel/, v3/, v4/ split and board infrastructure
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

Robert Allan JamesandClaude Sonnet 5 b031b802e3 Rename FABRIC series: FABRIC.md->0, FABRIC-2.md->1, FABRIC-3.md->2, FABRIC-4.md unchanged
FABRIC.md -> FABRIC-0.md
FABRIC-2.md -> FABRIC-1.md
FABRIC-3.md -> FABRIC-2.md (the current/living document)
FABRIC-4.md unchanged (new #3 to follow separately)

Every cross-reference repo-wide updated to match, including doc-comment
citations inside kernel source (.c/.h) files -- done via an ordered
placeholder substitution (FABRIC-3.md->placeholder2, FABRIC-2.md->
placeholder1, FABRIC.md->placeholder0, then placeholders resolved to
final names) in a single pass per file to avoid double-shifting
already-renamed references.

One line in capsules/font.4th grew past the 64-char block-format limit
as a side effect of the longer filename; shortened it and reverified
with mkcapsule --lint (34/34 pass) before rebuilding.

Verified 3-arch boot to ok> (amd64/aarch64/riscv64, each in the
foreground) after the fix; logs and DoE CSVs from this session's
verification runs included per this repo's own audit-artifact
convention.

Robert Allan JamesandClaude Sonnet 5 c07184e984 Add VMIdentity type, relocate homeblocks_sig_t off devblock 0
Phase A of the identity pipeline (FABRIC-3.md §F.2/§F.16, §F.13):

- New include/starkernel/vm_identity.h: VMIdentity{owner_pubkey[32],
  installed, acl_caps}, its own header per the project's "give real-shaped
  data its own header" convention (VMUuid's own precedent), embedded by
  value on struct VM. acl_caps is an independent capability bitmask, not
  an ordered privilege tier (decided 2026-08-28) -- Zuse isn't a
  structurally special VM, her identity just has every bit set
  (VM_IDENTITY_CAP_ALL). No individual capability bits assigned yet,
  deliberate slack matching blk_meta_t's own acl_reserved precedent --
  real bits get names once the operation they gate (BINDSTEP, MINT, ...)
  actually gets built.

- Applied the devblock-1 relocation decided in §F.13: new
  HOMEBLOCKS_SIG_START_FBLOCK constant (homeblocks_sig.h), repl.c's
  homeblocks_sig_check() call site updated from the literal 0. Also
  applied the still-owed blockmap_offset/blockmap_devblocks ->
  identity_src_offset/identity_src_devblocks rename decided in §F.6 (no
  other code referenced the old names). Updated the header's own stale
  GPT-relative doc comments to match -- GPT was dropped permanently, this
  location is final, not an interim stand-in.

Verified live on all three architectures: clean compile, clean boot to
ok>, Hermes/Artemis both confirmed live with no KILL (no regression from
last session's session-less fix). One pre-existing, unrelated anomaly
observed consistently on all three arches, not caused by this change (no
code touched here intersects Zuse's own fence-write path): "Zuse: minted
but fence write FAILED (not persistent)" -- flagged for its own
investigation, not chased here.

Robert Allan JamesandClaude Sonnet 5 2c45744995 Implement homeblocks_sig_check(): the drive signature check (Phase 8)
Real, complete verification logic -- not yet wired to any write path.
homeblocks_sig_check(dev, sig_start_fblock, out_sig) reads the 4
consecutive 1KB blkio forth-blocks the 4KB header spans, verifies
magic -> version -> CRC-64 in order, returns HOMEBLOCKS_SIG_OK/_BLANK/
_BAD_VERSION/_BAD_CRC/_READ_ERROR. Reuses block_subsystem.c's existing
CRC-64/ISO (compute_crc64, previously static/file-local, now exposed
via block_subsystem.h) rather than a second CRC implementation --
same algorithm already proven via per-block checksums. Takes the
header's starting block as a plain parameter rather than resolving it
internally: verifies a signature given a location, finding that
location (GPT-partition-relative) stays the caller's job.

Verified against the actual shipped code, not a reimplementation: a
standalone host test links the real homeblocks_sig.c against a fake
in-memory blkio_dev and exercises all four outcomes -- blank media,
a correctly-minted header (round-trips drive_uuid/minted_time_ns), a
flipped CRC, an unrecognized version. All four pass. A full
QEMU-hotplug live test isn't proportionate yet since nothing calls
this function from the live kernel path -- wiring it into the attach
path is the next punch-list item. Clean zero-warning compile and
clean boot on all three architectures confirms no build/link
regression from exposing compute_crc64 and adding the new source
file to every kernel build.

Robert Allan JamesandClaude Sonnet 5 10b96870c5 Add homeblocks_sig.h: drive signature header struct (Phase 8 kickoff)
Implements the design from the previous commit as-is: homeblocks_sig_t
(4096 bytes, magic+version+drive_uuid+timestamp+cert/blockmap offset
reservations+real hdr_crc), HOMEBLOCKS_SIG_PACK/_GET_MAGIC/_GET_VERSION
macros mirroring CAPSULE_MAGIC_PACK's bit layout, and a C99
compile-time size assertion matching stadium.h's own discipline.

Verified standalone (sizeof == 4096, clean under -std=c99 -Wall
-Wextra -Werror) -- nothing consumes this header yet, so no
functional kernel change and no 3-arch acceptance boot needed for this
step.
