 * No-op if sig->cert_offset is 0 (a genesis-mode Zuse drive has no cert
 * region -- that's capsule_zuse_boot_try_attach()'s own job, not this
 * one's) or if mama_vm has no installed Zuse cert yet (nothing to verify
 * the attached cert against). Otherwise: reads the cert devblock(s),
 * calls vm_identity_from_cert() against mama_vm's own zuse_cert_pubkey
 * and sig->drive_uuid. On success, reads the drive's own
 * user_identity_seed_t for its username and births a console VM +
 * RUNCAP-born user VM pair (idempotent -- no-ops if that username is
 * already live this session), installs the verified VMIdentity onto the
 * user VM, and registers the "<username>~user" pairing
 * (sk_repl_dispatch_line(), repl.c, looks for this). Does NOT USE the
 * new console automatically -- that stays an explicit, later,
 * ACL-gated step (BINDSTEP, §F.9), not something a bare attach should
 * trigger silently.
 *
 * @param dev     The just-attached, already-open block device.
 * @param sig     Its already-checked homeblocks_sig_t.
 * @param mama_vm Hera's own VM (the verifier -- her zuse_cert_pubkey is
 *                the trust root regular user certs are checked against).
