Claude 3bd81097e1 chore(license): an SPDX header on every source file that had none (LicenseRef-Starship-1.0) [skip ci]

The header scan (Captain Bob, 2026-11-10): 788 source files -- 351 with the
SL-1.0 header, 12 with the old name (docs/working/experiments, kept by
ruling), 31 under someone else's licence (tools/kconfig, Linux's, GPL-2.0:
kept), and 394 with none. Ruled: the SPDX form; capsules (.4th, .f18) and
proofs (.thy) left for a ruling of their own (mkcapsule's 64x16 block format,
content-addressed capsules).

253 files now begin

as a /* */ block (C, headers, assembly, linker scripts) or # lines (scripts,
Makefiles, Kconfig; below a shebang or a coding line); tools/mkcapsule.c,
which had the copyright line, gets the SPDX line only.

Not touched: docs/working/ (archive and old campaign material, as the
ruling kept the experiments); v4/system/post_cases.c (generated by
v4/tools/mkpost.py, "do not edit" -- the generator has the header).

Comments only: the kernel builds on amd64, aarch64, riscv64; make -C v4
test-32: 39 programs, 0 failures; every changed script parses.

boards: the amd64 target is PC -- a generic x86-64 UEFI PC, not the SER5

README.md

PC boot media (generic x86-64, UEFI)

make boot_image TARGET=PC builds build/boards/pc/lithos-pc.img: a GPT disk with one FAT32 EFI System Partition, for any x86-64 PC whose UEFI firmware boots a removable medium. Write it to a USB stick with dd. The partition holds:

EFI/BOOT/BOOTX64.EFI: the amd64 monolithic loader, with the whole kernel embedded. Firmware finds it through the UEFI removable-media path, so no boot entry has to be created.
startup.nsh: runs the loader if the firmware drops into the UEFI shell.
starforth.cfg: the boot arguments -- system=v4 as built; change the word to system=v3 to boot v3 (and KERNEL_ARGS="..." adds to it).

Beside the image, lithos-pc.spdx / .spdx.json: its SBOM, every file on it with its SHA-256.

Nothing in the image is specific to one machine: it follows the generic UEFI/ACPI path in FABRIC-3.md §III. Until 2026-10-14 this target was named SER5, after the first PC to be brought up -- a Beelink SER5 (AMD Ryzen), which is still the one on the bench (boards/BRINGUP.md).

Status: booted in QEMU (q35 + OVMF, from this image as its own disk): v4 as built, v3 with system=v3. Not yet booted on real hardware.
