internal/localapi: per-guest local-API server (doc 03 §6) — 7 self-scoped endpoints, hashed per-guest token store, persisted self-signed leaf with stable SHA-256 pin, optional 6th daemon goroutine. internal/provision: back-half — mint token, render bootstrap.json (no registry cred), write 0600, chown 100000:100000, attach pct-set bind mount (host-side, F3, no pct exec). --selftest=provision. build-golden.sh bakes the controller image + bootstrap unit. sudoers FELHOM_PROVISION; firewall narrowing artifact.
