# Orientation brief — eng-coulomb-railiance01-ho-001

**Status:** scaffold (RU-03)
**Date:** 2026-07-16

## Context for host-operator

- First forward-deployed host-operator pilot for coulomb on **railiance01**
- Prior agency craft: sys-medic + k3s node health protocol
- Related ops docs live in `railiance-hosts` (inventory, forgejo-on-railiance01, ADR-004 runner)
- No prior engagement vault session history

## Coach notes

If project memories exist on related repos, run:

```bash
kaizen-agentic memory brief sys-medic --target <related-repo>
```

Paste relevant non-secret patterns here. Until then, treat baseline as empty and
build envelope from first observe session.

## Watch from inventory/docs (pre-memory)

- Single-node k3s production sensitivity
- Privileged runner/DinD implications
- Prefer observe-class first session

## RU-03 mark

When this file is accepted as orientation, mark RU-03 `done` in
`checklists/ramp-up-status.md` (scaffold counts as filed; refresh after first live session if needed).
