The shared front half of provision and guest-loss DR as a journaled reconcile job
(internal/reconcile/bringup.go), mirroring the restore-test's crash-safety but keeping
the guest on success and applying a scenario-specific identity policy. Agent-only; no
hub/wire change. Grounded by the slice-7 bring-up spike (commit 3342993): F1/F3/F4.
- RunBringUp: restore -> reset identity -> size -> attach mounts -> start link-up;
verdict is liveness (waitRunning), success KEEPS the guest.
- identity policy: provision = fresh MAC (net0 sans hwaddr -> PVE regen) + hostname,
host-side; machine-id/host-keys regenerate guest-side (systemd + baked golden unit).
dr_guest_loss = preserve continuity (keep hostname; keep MAC unless KeepMAC=false).
- compensating rollback: mid-flight failure destroys the just-created guest
(SameTxnCreated provenance, gated); new Rollback journal flag + Recover.recoverBringUp
reap a half-built guest from a crash.
- F4: coalesced config PUT + bounded retry on the transient PVE config-lock 500 only.
- --selftest=bring-up (mode/archive/vmid/hostname/keep).
- configs/build-golden.sh: validated golden recipe incl. the F3 first-boot host-key unit.
- doc-03 §9 + identity-reset settled/implemented.
Deferred (stated): provisioning back half -> slice 8; host-loss DR + escrow consumption
and the BringUpSpec source (hub desired-state) -> slice 10.
