# 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

| Approver | Decision | Date | Notes |
|----------|----------|------|-------|
| _none_ | pending | | Dry-run only for RU-08 |
