Hermes VM 76ef17f26b feat(vm): Phase 2.3 closure — OOM watchdog + orphan-container docs 
OOM watchdog:
- vm-oom-watchdog.sh — scans journalctl -k since cursor for oom-kill,
  killed-process, and "out of memory ... killed" entries; maps cgroup
  hits back to container names via docker inspect; posts a single
  Telegram alert per scan window (no dedupe needed — cursor advances
  on every run). Cursor at /var/log/vm-oom-cursor, log at
  /var/log/vm-oom-watchdog.log.
- Systemd: OnBootSec=10min, OnUnitActiveSec=1h, Persistent=true.

Orphan containers (no compose file on disk):
- trading-backend → docker update --memory=768m (high-I/O bot)
- gitea-npm-registry → docker update --memory=512m
- orphan-containers.md captures canonical configs for recovery
  (env, mounts, networks, restart policy, memory limits).

Closes Phase 2.3 (post-monitoring) and Phase 3.3 (orphan limits).

README.md

Scripts

This directory is the preferred home for self-contained operational scripts.

Current Scripts

  • ubuntu-vm-security-update.sh
    • Supported.
    • Purpose: update and harden Ubuntu VMs with unattended upgrades, UFW, and fail2ban.
    • Risk level: high, because it modifies packages, firewall rules, and reboot behavior.
  • VMs/HostingerVM/vm-health-check.sh
    • Supported.
    • Purpose: read-only VM health and drift check for disk, memory, swap, Docker health, failed systemd units, and stale root crontab script paths.
    • Risk level: low, because it is read-only apart from an optional local log write.

Conventions

  • New standalone operational scripts should go here instead of the repo root.
  • Each script should document:
    • prerequisites
    • required environment variables
    • destructive or privileged behavior
    • example usage
  • Scripts that change host state should support --help and a non-destructive preview mode when practical.

Legacy Note

The repo root still contains older shell utilities. Those are not all deprecated, but new work should prefer scripts/ for clearer ownership and discoverability.
