# RU-08 — Privileged action proposal (DRY RUN — not executed)
|
|||
|
|
|
|||
|
|
**Engagement:** eng-coulomb-railiance01-ho-001
|
|||
|
|
**Date:** 2026-07-16
|
|||
|
|
**Author:** host-operator (grok session)
|
|||
|
|
**Status:** proposal only — **no human approval recorded; no changes applied**
|
|||
|
|
|
|||
|
|
## Purpose
|
|||
|
|
|
|||
|
|
Prove the privilege gate path: agent may **propose** privileged work; execution requires recorded human approval.
|
|||
|
|
|
|||
|
|
## Proposed actions (optional, priority order)
|
|||
|
|
|
|||
|
|
### P1 — Emergency swap file (if OOM imminent)
|
|||
|
|
|
|||
|
|
| Field | Value |
|
|||
|
|
|-------|--------|
|
|||
|
|
| Class | `privileged_ops` |
|
|||
|
|
| Blast radius | Host-wide; disk for swapfile; may pause I/O briefly |
|
|||
|
|
| Rollback | `swapoff` + remove swapfile |
|
|||
|
|
| Command sketch | create 2–4G swapfile on root FS (exact steps only after approval) |
|
|||
|
|
| Risk | Disk wear; masks capacity problem |
|
|||
|
|
|
|||
|
|
### P2 — journald vacuum
|
|||
|
|
|
|||
|
|
| Field | Value |
|
|||
|
|
|-------|--------|
|
|||
|
|
| Class | `privileged_ops` |
|
|||
|
|
| Blast radius | Historical logs discarded |
|
|||
|
|
| Rollback | none (logs gone) |
|
|||
|
|
| Command sketch | `journalctl --vacuum-size=500M` |
|
|||
|
|
| Risk | Loss of forensic depth |
|
|||
|
|
|
|||
|
|
### P3 — Package security upgrades
|
|||
|
|
|
|||
|
|
| Field | Value |
|
|||
|
|
|-------|--------|
|
|||
|
|
| Class | `package_upgrade` |
|
|||
|
|
| Blast radius | Service restarts; possible brief downtime |
|
|||
|
|
| Rollback | package-specific; may need restore |
|
|||
|
|
| Command sketch | `apt-get update && apt-get upgrade` (or unattended security only) |
|
|||
|
|
| Risk | Regression on production single-node |
|
|||
|
|
|
|||
|
|
### P4 — Restrict UFW sources for 6443/8472
|
|||
|
|
|
|||
|
|
| Field | Value |
|
|||
|
|
|-------|--------|
|
|||
|
|
| Class | `firewall_change` |
|
|||
|
|
| Blast radius | May lock out nodes/agents if mis-scoped |
|
|||
|
|
| Rollback | re-add rules |
|
|||
|
|
| Risk | High on single-node misconfiguration |
|
|||
|
|
|
|||
|
|
## Approval record
