Implements FABRIC-3.md §XXXII.2's scratch-thumbdrive mint mechanism: capsule_mint_identity_scratch() (capsule_mint.c/.h) builds a throwaway RAM-backed blkio_dev via blkio_ram.c's backend and runs capsule_mint_identity() against it completely unmodified -- same live Zuse-signing operation, same rng_get_bytes() draw for drive_uuid a real thumbdrive gets. Reads back only drive_uuid + the cert devblock; the seed devblock is written into the scratch buffer internally but never read out (no seed is ever baked into a capsule, per the ratified no-seed decision). New FORTH word MINT-SCRATCH (mama_forth_words.c), same stack signature as MINT, mints into the scratch device instead of any attached drive and never touches sk_repl_get_attached_blk_dev() or console-pairing state. Prints the drive_uuid as hex so a live boot log itself proves each call drew fresh entropy. Build correction found along the way: blkio_ram.c was excluded from the kernel build (Makefile.starkernel VM_EXCLUDE) alongside blkio_factory.c/blkio_file.c. blkio_factory_open() unconditionally references blkio_file.c's real fopen()/fread() file I/O, which has no freestanding-kernel equivalent, so the factory function couldn't be used as-is. blkio_ram.c itself is pure memcpy over a caller buffer -- pulled it alone into the kernel build and wired it directly in capsule_mint.c, the same way blkio_factory.c's own extern declarations do internally. Verified live on amd64: two MINT-SCRATCH calls produced two genuinely different drive_uuids (b533246d.../ae11b2b2...), confirming fresh entropy per call rather than stale reuse; VM stayed healthy afterward (5 6 + . -> 11). Clean 3-arch qemu boot (amd64/aarch64/riscv64), logs and DoE CSVs committed per standing convention. Remaining punch-list items (hand-transcription into a .4th block, the unattended-birth call site, the ACL cap bit) not started.
