One boot, v4/system/boot.c, for both products: it starts the nucleus image, finds each capsule in the baked capsule directory, recomputes its hash, checks its signature, gives its blocks to the node a line at a time, and prints PARITY:V4_NUCLEUS, PARITY:V4_CAPSULE and PARITY:OK before the prompt. A line the node does not accept ends the boot with the capsule, block and line named. docs/v4.0.0/NUCLEUS.md. - hosted Linux product for amd64, aarch64 and riscv64 (make -C v4 hosted); make -C v4 hosted-check boots all three and requires identical output - the kernel's v4 entry (STARFORTH_V4=1) calls the same boot - capsules/v4/forth79.4th, block 6000: no definitions yet - mkimage builds the nucleus only; no FORTH source is compiled at build time - capsule_blocks.c: the Block-header parse, free of any VM, for every loader Verified: make -C v4 test passes; hosted-check passes on the three ISAs with the same hashes; the kernel compiles with STARFORTH_V4=1 on the three. Not verified: no bare-metal boot of v4 has been run. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

/* capsule_blocks.h -- the block format of a .4th capsule payload.

*
|
|
* A .4th capsule is text: "Block <num>" header lines, each followed by that
|
|
* block's content lines (tools/mkcapsule.c, validate_forth_blocks). This is
|
|
* the one place that says what a header line is. It depends on no VM, so
|
|
* every loader of capsules can use it: the kernel's and the hosted v4
|
|
* system's (docs/v4.0.0/NUCLEUS.md 5.3).
