# Agent Guidelines

## Agent Authority (NON-NEGOTIABLE)

**No work is permissible on any system without an approved Redmine ticket.
There are no exceptions to this rule.**

### Scope of authority

1. **Tickets govern all work.** The agent performs ONLY the work described in
   the approved Redmine ticket. Anything outside that scope — no matter how
   small, helpful, or "obvious" — is prohibited.

2. **No autonomous system changes.** The agent does not modify, configure,
   create, delete, or grant anything on a production system unless it is
   explicitly directed by an approved ticket. "Production system" means
   every system in the fleet — there is no "test" exception unless the ticket
   says so.

3. **Propose, never implement.** If the agent discovers additional work that
   should be done — a bug, a misconfiguration, a missing dependency, an
   enhancement — it does NOT implement it. Instead, it creates a Redmine
   sub-ticket (status Feedback) describing the finding and surfaces it to
   the user for approval.

4. **Security and access changes require extra scrutiny.** Changes to sudoers,
   SSH keys, user accounts, firewall rules, authentication policy, file
   permissions, or any privilege-related configuration are treated as
   policy decisions, not implementation details. The agent may suggest
   them but NEVER implements them without explicit user direction in the
   ticket or a sub-ticket the user has approved.

5. **The user makes policy. The agent implements policy.** The agent does
   not decide who gets sudo, what keys go where, what services run, or what
   the access model is. The agent executes the user's decisions, exactly
   as specified.

6. **When in doubt, ask.** If the ticket is ambiguous, if a task seems to
   require something not explicitly authorized, or if the agent is unsure
   whether an action is in scope — STOP and ask the user via the ticket
   or directly. Asking is always acceptable. Overstepping is never
   acceptable.

7. **NEVER close a ticket without explicit user permission.** You may
   SUGGEST a close when the result is clearly scoped and delivered. If
   it's ambiguous whether the work is truly complete, don't suggest a
   close — leave that decision to the user. This applies to ALL tickets,
   no exceptions.

### Access-channel policy: SSH only (NON-NEGOTIABLE)

**The qemu guest-agent is NEVER an access, execution, or key-delivery
channel.** SSH (`sshd`) is the only approved remote access path. Every
command must flow through sshd so it is captured by the standard
auth/logging/audit infrastructure. This is an ITAR/CMMC/TS/SCI
environment — there is no back-door exception, ever.

- **Forbidden:** `qm guest exec` (runs arbitrary commands inside a guest
  over an unaudited channel) and any wrapper around it (e.g. a `vm-guest`
  mode). This includes using guest-agent to *deliver* an SSH key, even if
  the resulting SSH login is itself audited — the delivery bypassed audit.
- **Allowed:** installing or checking qemu-guest-agent for its intended
  purpose — letting Proxmox see guest state (`qm guest cmd <id> ping`,
  `agent: 1` config, `apt install qemu-guest-agent`). Visibility only;
  never execution.
- **Enforced mechanically:** `scripts/check-rules.sh` rule #11 fails on
  any `qm guest exec` / `vm-guest` pattern in code. `tests/remote.sh` has
  no guest-exec mode.
- **If a system is locked out** (no SSH key, no guest-exec path): surface
  it to the user. Do NOT improvise an alternate back-channel. The user
  authorizes the unblock method (console login, credential, etc.).

### Ticket-closing policy (NON-NEGOTIABLE)

**NEVER close a Redmine ticket without explicit user permission.** You
may SUGGEST a close when the result is clearly scoped and delivered. If
it's ambiguous whether the work is truly complete, don't suggest a close
— leave that decision to the user. This applies to ALL tickets, no
exceptions.

### What this means in practice

- Discovered a typo in a config during approved work? **Finish the approved
  work. Create a sub-ticket for the typo. Do not fix it inline.**
- Think a system should also have localuser sudo configured? **Do not add
  it. Propose it in a sub-ticket.**
- Need to install a package the ticket didn't mention? **Ask first.**
- Found a security issue? **Create a ticket immediately with full details.
  Do not remediate without approval.**

This environment operates in ITAR/CMMC/TS/SCI space. Every action must be
traceable to an approved ticket. There is no "I thought it would help."

## Quick Start

**You are an AI agent working on this project. Your first actions, in order:**

> **SESSION-START GATE (NON-NEGOTIABLE):** Steps 1-3 orient you. Step 4 is the
> check-for-understanding gate (rule summary). Steps 5-7 gather state. Step 8 is
> the scope-alignment gate. You MUST NOT begin any task work until the user
> (a) confirms your rule summary AND (b) names the ticket to work on. This runs
> **every session, automatically** — the user should never have to ask for it.

1. **Set up the environment:** `bash scripts/setup-hooks.sh` (installs git hooks — idempotent).
2. **Read this file** (`AGENTS.md`) — project policy and domain knowledge.
3. **Read the latest questions file** (`questions-v*.md`) — open questions awaiting human input. The version number increments each round (v1, v2, v3...).
4. **Check for understanding — GATE.** In your own words, summarize ALL the rules
   back to the user before doing any work: Agent Authority (ticket-governed,
   propose-never-implement), Access-Channel SSH-only policy, Remote access
   (remote.sh chokepoint mandatory, DNS names only — never IP literals),
   Questions policy (no harness question-tools), Documentation policy
   (Discourse is SoR), Redmine tracking, Git policy (always commit+push,
   shellcheck), Mandatory infra-change documentation (#298 audit log), SSH
   routing chokepoints (`tests/remote.sh`), the mechanically enforced
   `check-rules.sh` rules, and Credentials (Vault migration TODO). Then stop
   and wait for the user to confirm. This checkpoint guarantees every
   session starts aligned.
5. **Check Redmine** — `docker run --rm --env-file ~/.creds/redmine.env git.knownelement.com/reachableceo/redmine-cli:latest list --assigned-to-me -p 55` for active work.
6. **Check current state:** `git log --oneline -10`.
7. **Run rule audit:** `bash scripts/check-rules.sh --fast`.
8. **Scope-alignment — GATE.** Present the session handoff's "What's Left"
   priority list (or the Redmine queue if no handoff exists). Do NOT scan the
   full ticket queue and pick work on your own — **the user directs what gets
   worked on, always.** Note any new or urgent items from the Redmine check,
   then ask which ticket to work on tonight. **STOP and wait.** Do not set
   `.crush/active-ticket`, do not read systems, do not run diagnostics, until
   the user names the target. This gate prevents the agent from burning
   context on work the user didn't ask for.

## Enforcement Model

Git hooks (`scripts/pre-commit`, `scripts/pre-push`) enforce the rules defined in
`scripts/check-rules.sh`. The rules engine checks: shellcheck (zero warnings
including info-level), Docker image pinning (no `:latest`), container naming,
required files, Discourse pointer headers, and more. Run `bash scripts/check-rules.sh`
for a full audit or `--fast` for pre-commit speed. Bypass with `--no-verify`
(emergencies only).

## Task Tracking

- **Redmine is the system of record for all work.**
- **NEVER close a ticket without explicit user permission.** Suggest a
  close when clearly scoped/delivered; if ambiguous, don't suggest.
- **Ticket-first enforcement (mechanically enforced).** Before starting
  any work, set the active ticket: `echo '#NNN' > .crush/active-ticket`.
  The Crush hook (`hooks/ticket-gate.sh`) blocks modifying operations
  until this file exists. If no ticket exists, CREATE ONE FIRST via
  redmine-cli, then set it. Clear when done: `> .crush/active-ticket`.
- **WORKING.md** is the only in-repo task tracker — a scratchpad for the current
  session. The pre-commit hook blocks commits while any task remains unchecked.
- Clear WORKING.md before responding to the user.

## Rolling HUD (session-scoped, NOT persisted)

The rolling HUD is a **live status display** the agent maintains throughout
the session to help the human follow along. It is NOT a system of record —
Redmine, Discourse, and git are the durable systems. The HUD exists purely
for the human's situational awareness during the session.

- **Format:** a compact block shown at the end of each significant response
  (after completing a step, hitting a blocker, or pivoting). Example:

  ```
  ┌─ SESSION HUD ────────────────────────────────────────
  │ Active: #343 (Monitoring coverage matrix)
  │ Done:   ✓ scope-alignment gate added to both AGENTS.md
  │         ✓ committed + pushed (6a2550b)
  │ Now:    drafting coverage matrix on Discourse
  │ Next:   → #341 TEMPer USB (deploy on pfv-tsys1)
  │         → #338 LibreNMS alerts (BLOCKED: pushover.env)
  ├─ USER ACTION ITEMS ──────────────────────────────────
  │ • Populate ~/.creds/pushover.env (unblocks #338, #428)
  │ • Populate ~/.creds/prometheus.env + grafana.env (#430)
  └──────────────────────────────────────────────────────
  ```

- **Placement:** may be written to `.crush/hud.md` on disk to keep context
  window smaller (re-read and update rather than hold in memory). Never
  committed to git. Wiped at session end.
- **Sections:**
  - **Active:** current ticket number + one-line description
  - **Done:** ✓ items completed this session (append as work progresses)
  - **Now:** what the agent is actively doing
  - **Next:** the queued items (per handoff priority or user direction)
  - **User action items:** things ONLY the user can do (populate creds,
    physical work, manual deploys) with the tickets they unblock
- **When to show it:** after each logical unit of work, at blockers, and
    when pivoting between tickets. Not every trivial response — use judgment.
- **NOT a substitute for Redmine/Discourse/git.** The HUD is ephemeral. When
    work completes, update the durable systems (ticket notes, Discourse wiki,
    commits). The HUD just tracks the live narrative for the human.

## Working Style

- **Stop over-thinking.** Get to code and output faster. Explore with code;
  gather ground truth. Do not burn tokens reasoning about things a quick command
  answers.
- **Farm work out to deterministic tooling:** linters, LSPs, formatters, test
  runners. If an LSP is wired up, use it; otherwise pull a Docker image and lint
  inside it.
- **Use sub-agents as subcontractors:** scoped spec in, distilled deliverable out.
  Never read 10+ files sequentially; batch into agent calls.
- **Command timeouts (NON-NEGOTIABLE):** Every command that touches a remote
  system MUST be wrapped with `timeout`. Hard limits: 30s for quick reads
  (status, ps, ls), 120s for standard operations, 300s for deployments/pulls.
  If a command hits the timeout, STOP and investigate root cause — never
  blindly retry. A hung command is a failed command. Detect failure fast,
  diagnose, fix, move on. Example: `timeout 120 bash tests/remote.sh vm 'cmd'`.
  This applies to ALL tools — bash, docker, CLIs, sub-agents.

## Questions (NON-NEGOTIABLE)

**NEVER use a harness "question"/"ask user" tool** (structured prompts,
modal forms, tabbed questions). Banned across every project, every harness.
They are not portable, not version-controlled, and bypass the git record.
**All questions go in the current `questions-v(N).md` file** — write the
question; the human edits the answer inline in the same file. **Version up
the filename each time answers land** (v1 → v2 → v3...): create
`questions-v2.md` with resolved Q&A marked, new questions appended. This
preserves the history of each Q&A round. Synthesize resolved Q&A into
Discourse (decisions) and Redmine (work items). See `BASELINE-PROMPT.md`
§10.

## Documentation policy (IMPORTANT)

**Discourse is the canonical source of truth for all knowledge documentation.**
Knowledge docs (architecture, runbooks, references, audits, policies) have been
migrated to [community.turnsys.com](https://community.turnsys.com/c/vp-techops)
as wiki topics in the **VP TechOps** category.

All `.md` files in this repo (except `AGENTS.md` and `LICENSE`) are now
**pointers** that link to their corresponding Discourse topic. **Do not update
documentation content in git** — edit the Discourse wiki topic instead. Git
edit history no longer serves as the documentation changelog; Discourse
preserves wiki edit history automatically.

Code (scripts, configs, playbooks) still lives in git as the source of truth
for executables. Only *documentation* moved to Discourse.

## Top-level files

All `.md` files now point to Discourse. The key pointers:

| File | Points to | Discourse topic |
|------|-----------|-----------------|
| `README.md` | Project overview | [#296](https://community.turnsys.com/t/296) |
| `STATUS.md` | Ticket index + infra summary | [#297](https://community.turnsys.com/t/297) |
| `docs/docmap.md` | Documentation index | [#296](https://community.turnsys.com/t/296) |

Work tracking stays in [Redmine](https://projects.knownelement.com).

## Repository Layout

```
dcinfra/            Data-center infra: PDU (powerman), serial console (console), UPS (ups)
netinfra/           DNS/NTP/DHCP setup + audit; DNS cluster replication (dns-cluster-setup);
                    switch captures (switches); DHCP config (dhcp)
k8s/                k3s cluster setup scripts (HA control plane over Tailscale) + docs/
proxmox/            Proxmox fleet docs (hardware audit, capacity, storage) + perf tuning (perf/)
awx/                Ansible AWX deployment (k3s + AWX Operator)
tests/              Test suite + VM validation harness + remote.sh SSH chokepoint
scripts/            Framework: git hooks, rule engine (check-rules.sh), shared lib
docs/               Server-build docs, docmap index, and archive
archive/            Historical/superseded code (provisioning -> replaced by KNELIAC project)
vendor/             Vendored KNELShellFramework
```

- **Server provisioning moved to KNELIAC**: The
  [`archive/provisioning/`](archive/provisioning/) tree is historical. Active
  server provisioning lives in the **KNELIAC** project at
  `/home/reachableceo/projects/KNELIAC`.
- **Non-bash files**: Some files under `archive/provisioning/Agents/` have `.sh`
  extension but are PHP (shebang `#!/usr/bin/php`). Skip in syntax checks.
- **Remote access (NON-NEGOTIABLE):** ALL SSH/SCP to ANY host MUST go
  through the chokepoint scripts — [`tests/remote.sh`](tests/remote.sh)
  (Proxmox hosts + all VMs) or
  [`netinfra/dns-cluster-setup/remote-dns.sh`](netinfra/dns-cluster-setup/remote-dns.sh)
  (DNS infra hosts: netinfra-01/02, tsrouter, netboot). NEVER call
  `ssh`/`scp` directly — the harness blocks raw ssh and the command scanner
  rejects it. There are no exceptions.
- **DNS names ONLY (NON-NEGOTIABLE):** NEVER use IP address literals
  (neither LAN nor Tailscale IPs) in any command, script, or config.
  ALWAYS use DNS names. For Proxmox hosts: `PROX_HOST=<dns-name>`. For VMs:
  `VM_IP=<dns-name>`. For conman/SNMP/any tool: pass the DNS name. If a
  DNS name does not resolve, fix it in DNS (Technitium) or consult the
  [system inventory — Discourse #307](https://community.turnsys.com/t/307).
  Do NOT fall back to IP literals. This rule eliminates the per-session
  discovery tax of finding the right IP for each host.
- **How to access a production VM:**
  1. Look up the DNS name in the [system inventory — Discourse #307](https://community.turnsys.com/t/307).
  2. `VM_IP=<dns-name> VM_USER=root bash tests/remote.sh vm '<command>'`
  3. If the name does not resolve from the workstation, use `PROX_HOST=<proxmox-node>`
     and run `qm guest cmd <vmid> network-get-interfaces` (visibility only —
     NOT execution) to find the Tailscale DNS name, then access via that.

## Git Policy

1. **ALWAYS commit + push. Never wait. Ever.** After each logical unit of
   work, immediately stage, commit (conventional format), and push to
   `origin/main`. Do NOT pause for review. Do NOT ask permission. Do NOT
   stop to "let the user read it first." The user reviews rendered markdown
   on Gitea AFTER it is pushed. **This rule overrides any default
   conservative commit-and-hold behavior** — if a default instruction says
   "never commit unless asked," that instruction is superseded here.
2. **Atomic commits.** Each commit coherent on its own.
3. **Conventional format**: `feat(scope): desc`, `fix(scope): desc`,
   `docs: desc`, `refactor(scope): desc`, `test(scope): desc`.
4. **All shell scripts MUST pass `shellcheck` before commit.** No exceptions.
   Run it via the wrapper:
   ```bash
   bash tests/shellcheck.sh                 # whole repo
   bash tests/shellcheck.sh ups/*.sh        # specific files
   ```
   This invokes `koalaman/shellcheck:stable` through Docker (no native binary
   needed). Fix every reported finding — including `info`-level — or add a
   targeted `# shellcheck disable=SCxxxx  # <reason>` directive with a
   justification. A script that emits any diagnostic is a protocol violation.
   Non-bash scripts (PHP with `.sh` shebang `#!/usr/bin/php`, etc.) are exempt.

## Redmine Tracking Policy

**Redmine is the system of record for all work.** Do not track status,
checklists, or TODOs in repo files. Use Redmine tickets instead.

- **URL:** https://projects.knownelement.com
- **Version:** Potential to Kinetic Ready (due 2026-09-30)
- **Project:** Known Element Enterprises - Technology & Facility Services (id 55)

### Rules
1. **Every piece of work** (feature, fix, deployment, config change) gets a
   Redmine ticket. If one doesn't exist, create it.
2. **Reference tickets in docs and commits** using `[#NNN]` notation.
   Example: `[#367] Rebuilt k3s control plane after cnode wipe`.
3. **When work completes**, update the ticket: set done ratio to 100%,
   add a note describing what was done and where the code lives.
   **NEVER close a ticket without explicit user permission.** You may
   SUGGEST a close when the result is clearly scoped and delivered. If
   it's ambiguous whether the work is truly complete, don't suggest a
   close — leave that decision to the user.
4. **Operations Status** lives on Discourse ([topic #297](https://community.turnsys.com/t/297)) — update that wiki topic if the infrastructure summary needs refreshing. The `STATUS.md` file in git is now a pointer only.
5. **Link code to tickets** — ticket descriptions and notes should reference
   the relevant file paths in this repo (e.g., `dcinfra/ups/`).

### CLI access (read + write)

Tickets are managed via the `redmine-cli` container, invoked directly
with `docker run` (no wrapper script). Full command reference, patterns, and
the subtask escape hatch live in the CLI's own `AGENTS.md`
(`~/projects/KNEL-AIMiddleware/tooling-cli/redmine/AGENTS.md`) — read it
for anything beyond the basics.

```bash
# Connection sanity check (run first in any session):
docker run --rm --env-file ~/.creds/redmine.env \
    git.knownelement.com/reachableceo/redmine-cli:latest whoami

# Your queue (project 55):
docker run --rm --env-file ~/.creds/redmine.env \
    git.knownelement.com/reachableceo/redmine-cli:latest list --assigned-to-me -p 55

# Show / create / update / close:
docker run --rm --env-file ~/.creds/redmine.env \
    git.knownelement.com/reachableceo/redmine-cli:latest show 367
docker run --rm --env-file ~/.creds/redmine.env \
    git.knownelement.com/reachableceo/redmine-cli:latest create -p 55 -s "Subject" -d "desc"
docker run --rm --env-file ~/.creds/redmine.env \
    git.knownelement.com/reachableceo/redmine-cli:latest update 367 -n "Done: committed in abc123" --done-ratio 100
docker run --rm --env-file ~/.creds/redmine.env \
    git.knownelement.com/reachableceo/redmine-cli:latest close 367
```

Key IDs: project **55** (`technicaloperations`), user **5** (`reachableceo`).
Statuses: New(1), In Progress(2), Resolved(3,closed), Feedback(4), Closed(5),
Rejected(6). New subtasks go to **Feedback (4)**. Tracker **3** = Support.
**Gotcha:** `create` has no `--parent` flag — to make a subtask, use the
`python-redmine` escape hatch inside the container (see
`tooling-cli/redmine/AGENTS.md`). Always `show` a ticket before updating it.

Credentials (`REDMINE_URL`/`REDMINE_API_KEY`) live in the centralized store
at `~/.creds/redmine.env`.

## Documentation Workflow

**Discourse is the source of truth for all knowledge docs.** After any work
session, an agent MUST:

1. **Update Discourse wiki topics** — if infrastructure facts changed (new
   VM, IP change, host retired), edit the relevant wiki topic at
   [community.turnsys.com/c/vp-techops](https://community.turnsys.com/c/vp-techops).
2. **Update the Operations Status topic** ([#297](https://community.turnsys.com/t/297))
   if tickets were opened or closed.
3. **Grep for stale paths in code** — `grep -rn 'old/path' --include='*.sh'`
   after any rename or restructure. Fix all references in the same commit.
4. **If a new top-level directory was created**, update:
   - `AGENTS.md` → "Repository Layout" code block
   - `AGENTS.md` → "Key Scripts" table (if it has an entrypoint script)
   - Create a new Discourse wiki topic for any documentation
5. **Self-audit before commit.** Code changes must be internally consistent.
   Documentation changes go to Discourse, not git.

### CLI access (read + write)

Wiki topics are managed via the `discourse-cli` container, invoked directly
with `docker run` (no wrapper script). Full command reference, patterns, and
the raw-API escape hatch live in the CLI's own `AGENTS.md`
(`~/projects/KNEL-AIMiddleware/tooling-cli/discourse/AGENTS.md`) — read it
for anything beyond the basics.

```bash
# Connection sanity check (run first in any session):
docker run --rm --env-file ~/.creds/discourse.env \
    git.knownelement.com/reachableceo/discourse-cli:latest whoami

# List VP TechOps topics:
docker run --rm --env-file ~/.creds/discourse.env \
    git.knownelement.com/reachableceo/discourse-cli:latest ls -c vp-techops

# Show a topic / edit a wiki post (find post id via `show`):
docker run --rm --env-file ~/.creds/discourse.env \
    git.knownelement.com/reachableceo/discourse-cli:latest show 297
docker run --rm --env-file ~/.creds/discourse.env \
    git.knownelement.com/reachableceo/discourse-cli:latest update <post_id> -b "new markdown body"
```

VP TechOps = category **74**. Key topics: #296 (project overview), #297
(ops status), #298 (audit log). The API user is trust-level 4 but **not
admin** — admin-only ops (category creation, setting the wiki flag) will
403; surface those to the user rather than retrying. **Gotcha:**
`update`/`delete` take a post **id**, not a post number. Never create a new
topic for an update to existing knowledge — edit the wiki post in place.

Credentials (`DISCOURSE_URL`/`DISCOURSE_API_KEY`/`DISCOURSE_API_USERNAME`)
live in the centralized store at `~/.creds/discourse.env`.

## Switch Console Access (conman)

Switch configs are pulled via serial console through a conman + ser2net
stack on pfv-tsys4.

- **conmand server:** pfv-tsys4 (port 7890)
- **ser2net:** pfv-tsys4, TCP ports 2001-2006
  (do NOT connect to ser2net directly — it conflicts with conman's
  persistent sessions; always use the conman client)
- **Script:** [`proxmox/perf/scripts/conman-console.py`](proxmox/perf/scripts/conman-console.py)
  — drives console sessions read-only via PTY. No expect/tcl required.
- **Command files:** [`netinfra/switches/`](netinfra/switches/) — `.cmds` files
  with switch-specific show commands
- **Query available consoles:** `conman -d 100.70.77.93 -q`

```bash
# Pull a switch config (example):
CONMAN_SERVER=100.70.77.93:7890 python3 proxmox/perf/scripts/conman-console.py \
  --console pfv-r5-core-01 --cmds netinfra/switches/pfv-r5-core-01.cmds
```

| Console name | TCP port | Device |
|--------------|----------|--------|
| pfv-r5-core-01 | 2001 | Dell PowerConnect 5448 (rack 5 core, mgmt+storage) |
| pfv-r3-tor-mgmt-01 | 2002 | Dell PowerConnect 5324 (rack 3 mgmt TOR) |
| pfv-r3-tor-stor-01 | 2003 | Dell PowerConnect 5324 (rack 3 storage TOR) |
| pfv-rrinfra-rtr | 2004 | Cisco router (rrinfra) |
| pfv-r2-tor-01 | 2005 | Rack 2 TOR switch |
| pfv-r6-mgmt-01 | 2006 | Rack 6 management switch |

## Mandatory: Document ALL Infrastructure Changes

**This is non-negotiable. Every infrastructure change (VM config, disk
cache, network setting, service config, storage migration) MUST be
documented BEFORE moving to the next task step — not "later" or "at the
end."**

Required for EVERY infrastructure change:

1. **Redmine ticket** — create one if none exists. Reference as `[#NNN]`.
2. **Discourse audit log** — reply to topic
   [#298](https://community.turnsys.com/t/298) with a dated entry (what
   changed, why, where).
3. **Discourse relevant wiki topic** — update the architecture/reference
   topic if the change affects documented infrastructure facts (storage
   #300, network #299, k8s #305, etc.).
4. **Git commit** — if code/config changed in the repo, commit + push
   immediately per the Git Policy above.

## Tooling

- `gh`, `docker`, `jq` available on the workstation.
- No native shellcheck — use `bash tests/shellcheck.sh` (Docker wrapper
  `koalaman/shellcheck:stable`). ALL scripts must pass including info-level.
- For raw API calls not covered by the Redmine/Discourse CLIs, use
  `python3` inside the CLI Docker containers (escape hatch pattern in
  `tooling-cli/{discourse,redmine}/AGENTS.md`).
- `curl`/`wget`/`httpie` may be blocked by some harnesses. Use the CLIs or
  the python-in-Docker escape hatch for HTTP writes.

## Key Commands Quick Reference

```bash
# Tests + validation:
bash tests/run-tests.sh                        # test suite
bash tests/vm-validation.sh                    # VM validation
bash tests/shellcheck.sh                       # shellcheck whole repo
bash tests/shellcheck.sh path/to/*.sh          # shellcheck specific files

# Redmine + Discourse sanity checks (run first in any session):
docker run --rm --env-file ~/.creds/redmine.env \
    git.knownelement.com/reachableceo/redmine-cli:latest whoami
docker run --rm --env-file ~/.creds/discourse.env \
    git.knownelement.com/reachableceo/discourse-cli:latest whoami

# Proxmox host access (DNS names only — never IPs):
PROX_HOST=pfv-tsys5 bash tests/remote.sh prox 'qm list'
PROX_HOST=pfv-tsys5 bash tests/remote.sh prox 'pvesm status'

# Production VM access (DNS names only — never IPs):
VM_IP=tsys-librenms VM_USER=root bash tests/remote.sh vm 'systemctl status cron'

# DNS infra access:
bash netinfra/dns-cluster-setup/remote-dns.sh netinfra01-root 'systemctl status docker'

# Switch console (read-only config pull — DNS names only):
CONMAN_SERVER=pfv-tsys4:7890 python3 proxmox/perf/scripts/conman-console.py \
  --console pfv-r5-core-01 --cmds netinfra/switches/pfv-r5-core-01.cmds
```

## Credential Management

- API keys currently in `.env` files under KNEL-AIMiddleware (gitignored).
- User goal: migrate all keys to Hashicorp Vault
  (`vault.knownelement.com`). No vault token present yet
  (`~/.vault-token` missing). Track as high-priority TODO.

## Key Docs

→ **All documentation lives on Discourse:**
  [community.turnsys.com/c/vp-techops](https://community.turnsys.com/c/vp-techops)

→ All `.md` files in this repo are pointers to Discourse topics.

→ **Complete Linux System Inventory:**
  [Topic #307](https://community.turnsys.com/t/307) — every Linux system
  (hosts + VMs + physical), with Tailscale IPs, DNS names, SSH access
  status, and tuned profiles. Reference this for monitoring coverage,
  access management, and hostname consistency.

## Project Context

Solo-founder R&D Proxmox cluster in a private residence. Shoestring budget.
Production lives on a Cloudron VPS in Reston VA. See the
[Operations Status topic](https://community.turnsys.com/t/297) for the ticket
index and infrastructure summary.
All work is tracked in [Redmine](https://projects.knownelement.com)
(version: Potential to Kinetic Ready, due 2026-09-30).
