Adds the hand-transcription mechanism FABRIC-3.md §XXXII.2's punch list item 2 calls for: MINT-SCRATCH-EMIT prints the last successful MINT-SCRATCH's drive_uuid + cert devblock as ready-to-paste FORTH source (HEX-based CREATE ... C, ... byte sequences), so packaging an unattended identity into a capsule is a mechanical copy out of the captured boot log rather than a manual hex-to-FORTH translation an operator could transpose a digit in. Refuses (no output) if no MINT-SCRATCH has ever succeeded -- printing 4112 zero bytes as if they were a real identity would be a silent, misleading success, matching this session's own error-handling audit discipline rather than adding a new silent-failure primitive right after finishing one. Verified live on amd64: MINT-SCRATCH-EMIT correctly refuses before any mint, then after MINT-SCRATCH succeeds, emits UNATTENDED-ID-UUID and UNATTENDED-ID-CERT as valid FORTH literals. Cross-checked byte-exact: the cert's own embedded ASN.1 serialNumber field matches the emitted UUID bytes exactly, confirming x509_build_user_cert()'s drive_uuid binding round-trips correctly through the scratch-device path. Clean 3-arch qemu boot (amd64/aarch64/riscv64). Remaining punch-list items (writing/committing a real capsule file for an actual named identity, the unattended-birth call site, the ACL cap bit) not started -- authoring a real committed capsule needs a name/ purpose decision that isn't mine to make.

capsules/
FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.

Block namespace
Block ranges are shared across all loaded capsules — collisions cause silent word-definition overwrites.
| Range | Owner |
|---|---|
| 2048–2099 | init.4th |
| 2100–2199 | doe.4th |
| 3000–3999 | workload capsules |
| 4000+ | user-defined (ACL.4th, zuse.4th, …) |
Each block is limited to 1024 bytes. Verify with wc -c before committing.
