feat(v4.0.0): the nucleus is a capsule, sent to a node born empty
MESH.md step 2. A capsule of F18 code is the words a neighbour writes to a node's port: for each stretch of memory, "@p a! @p push", the address and count, "@p !+ unext" and the words; then a jump to the start. A node born empty executes that from its port, so it needs nothing in it beforehand. - capsule.h/.c: v4_capsule_write, any node's memory as such a capsule - mkimage writes the nucleus so, to capsules/v4/nucleus-64.f18, and the addresses a host needs as a C file; the memory image is no longer linked into either product - mkcapsule is unchanged: the nucleus capsule is a built file kept under capsules/, as BLOCK_MAP.md is, and is baked, hashed and signed with the rest - boot: the node is born empty (v4_image_born); the nucleus capsule is found, its hash and signature checked, and given to the node a word at a time as it reads its port; PARITY:V4_NUCLEUS carries its name and hash Verified: test_fabric.c (59 checks, both widths, and under ASan and UBSan): a memory with a programme and scattered words arrives word for word in an empty node and runs. The nucleus capsule rebuilds byte for byte. hosted-check passes on three ISAs; clean qemu with STARFORTH_V4=1 on amd64, aarch64 and riscv64 takes the nucleus in, passes POST (550 of 550) and answers lines typed at each prompt (logs/20261006-102421, -102706, -103048).

## 5. A capsule of F18 code, and how an empty node takes it in
|
||||
|
||||
**Proposal.** A capsule of F18 code is words of memory and where they go:
|
||||
runs of `(address, count, the words)`, and the address to start at. The
|
||||
nucleus image `mkimage` writes today is this already, as a C file linked
|
||||
into the binary; it becomes a capsule in the capsule directory, with a
|
||||
name, a hash and a signature like any other. (`mkcapsule` takes what is
|
||||
under `capsules/`; the nucleus is built, not written. How a built file
|
||||
enters the directory is to be settled when this is reached, and reported
|
||||
before it is done, since `mkcapsule` is v3's tool too.)
|
||||
**As built.** A capsule of F18 code is not a format a node has to
|
||||
understand. It is the words a neighbour writes to the node's port, in the
|
||||
order they are written: for each stretch of memory that is not zero the
|
||||
two instruction words below with their address and count and then the
|
||||
words themselves, and at the end a jump to where to start. The file is
|
||||
those words, each in a cell's bytes, low byte first, and its hash is the
|
||||
hash of exactly what is sent. The nucleus is one, in the capsule directory
|
||||
with a name, a hash and a signature like any other. `mkcapsule` was not
|
||||
changed: the nucleus capsule is a built file kept under `capsules/v4/`.
|
||||
|
||||
A neighbour puts it into an empty node by writing to the port between
|
||||
them, and the node executes what arrives (4.1). For each run it sends

2. **The nucleus as a capsule, and an empty node made a StarForth node
|
||||
through its port (section 5).**
|
||||
**Done 2026-10-06.** `v4/src/capsule.c`, `v4_capsule_write`: any
|
||||
node's memory as the words to send an empty node. `mkimage` writes the
|
||||
nucleus so, to `capsules/v4/nucleus-64.f18`, a built file kept in the
|
||||
tree as `BLOCK_MAP.md` is; `mkcapsule` is unchanged and bakes, hashes
|
||||
and signs it with the rest. The boot's node is born empty
|
||||
(`v4_image_born`) and is given the nucleus a word at a time as it reads
|
||||
its port, after the capsule's hash and signature are checked
|
||||
(`v4/system/boot.c`). Nothing of the nucleus is linked into either
|
||||
product any more. `test_fabric.c`: a memory with a programme and words
|
||||
here and there arrives word for word and runs. Both products boot so:
|
||||
`hosted-check` on three ISAs; `logs/20261006-102421`, `-102706`,
|
||||
`-103048`.
|
||||
**What a newborn node still has from its host:** the registers the
|
||||
nucleus expects — the console's three, the two stack registers, the
|
||||
error register, the fault table's address, the storage registers — are
|
||||
attached by the host when the node is born, from the description
|
||||
`mkimage` writes. They are the node's hardware as the golden model has
|
||||
it, at addresses the memory map (D-4, still open) will fix. The console
|
||||
and storage ones go when those become devices on ports (steps 3 and
|
||||
6).
|
||||
3. **Messages (section 6):** a StarForth node that reads messages when
|
||||
idle; the console as a device; a line typed is a message.
|
||||
4. **Finding the way (section 7).**
