| `Runner` / `ExecRunner.Run`, `RunStdin` | internal/proxmox/privileged.go | `Run(ctx, name, args...) (stdout, stderr []byte, err)` | ALL host command exec (direct or `sudo -n` prefix) | Arg vectors only, never a shell string; `capBuf` caps output at 1 MiB |
| `Privileged` (CreateGoldenLXC/MountUSBByUUID/SMART/Sensors) | internal/proxmox/privileged.go | methods on `*Privileged` | the 3 fenced root-CLI exceptions ONLY | Do NOT add methods — fence is structural (`routing_test.go` asserts it) |

| `Prober.Probe` | internal/capability/probe.go | `Probe(ctx) []Status` | live sudo-policy capability check (`sudo -n -l --`) | Needs a DIRECT runner (never the sudo-prefixing one — double-sudo); never executes probed cmds. v0.86.0: config-gated caps (`Capability.GatedBy` + `Prober.GateActive`) report `inactive`/"disabled by configuration" ONLY when healthy — broken plumbing stays degraded; the pbsdr-* gate answers from `pbsdr.Manager.DRConfigured` (marker-backed across restarts) |
| `stageTemp` | internal/localapi/intermediary.go | `stageTemp(pattern, content) (path, err)` | random-named temp before a root `install` (audit B1) | Fixed /tmp names are a TOCTOU — sudoers globs expect `/tmp/felhom-*-*.ext` |
| `guesthook.InstallSnippet` / `Register` | internal/guesthook/install.go | `InstallSnippet(ctx, runner) error` | pre-start self-heal hook install (C1 net) | Same random-temp+install pattern; snippet delegates to the agent binary (no shell logic). Issues `mkdir -p /var/lib/vz/snippets` FIRST (v0.63.0, B2 — fresh boxes lack the dir; sudoers grants exactly that argv) |
