Implements the unattended-birth mechanism FABRIC-3.md §XXXII.2 designed: UNATTENDED-BIRTH ( name-c name-u -- ok? ) births a VM from a named (p) capsule via capsule_birth_baby() (completely unmodified, the same generic build-time-capsule path CAPSULE-BIRTH already uses), then installs its identity the same way capsule_wirebind.c already does live for WIREBIND attaches -- vm_identity_from_cert() verification followed by a plain post-birth struct assignment -- rather than anything RUNCAP-shaped, since RUNCAP requires a real blkio_dev+ homeblocks_sig_t an unattended identity never has. The born VM's own capsule payload is expected to lay down two CREATE'd buffers (UNATTENDED-ID-UUID, UNATTENDED-ID-CERT) via MINT-SCRATCH- EMIT's own literal format; their addresses are fetched by interpreting a two-word line inside the *new* VM's own context (vm_interpret(born_vm, ...)), the same "run inside that VM's own dictionary" idiom capsule_wirebind.c already uses for VM-NAME-REG. Explicit invariant preserved: never touches g_wirebind_attached_username or any console-pairing state, births no console VM -- an unattended identity stays un-promptable (§VIII.1) until a human pairs a console to it later via the already-working VM-NAME-REG mechanism. Verified live end-to-end on amd64: minted a real test identity via MINT-SCRATCH, captured its MINT-SCRATCH-EMIT output, built a throwaway test capsule from it (discovered along the way: mkcapsule's real block constraints are range [2048,5120) and max 16 content lines per block -- neither matches this repo's own doc comment, corrected via ground truth from the tool itself, not assumed), then ran UNATTENDED-BIRTH against it: cert verified against Zuse's root pubkey, identity installed, "no console attached" reported, Hera stayed healthy afterward (5 6 + . -> 11). Test capsule reverted after capture per this project's own probe convention -- not a real identity, never committed. Clean 3-arch qemu boot (amd64/aarch64/riscv64) on the real committed C-only change. Remaining punch-list item (the ACL cap bit for console attachment) not started.
