fix(console): enable conmand remote access + add conman client script

conmand was binding to localhost only (server loopback=on default), so
the conman client on workstations couldn't connect. The intended workflow
is: conman client (workstation) → conmand (pfv-tsys4:7890 over Tailscale)
→ ser2net (TCP 2001-2007) → serial device. Without remote conmand access,
users had to telnet directly to ser2net, which conflicts with conmand's
persistent connections (kickolduser kicks the telnet session immediately).

Changes:
- generate-config.sh: add server loopback=off to conman.conf so conmand
  listens on 0.0.0.0:7890 (reachable via Tailscale)
- query-remote.sh: new script for workstations — installs conman client,
  verifies connectivity, lists or connects to consoles
- README.md: clarify access model (conman primary, telnet emergency only
  with conmand stopped). Document the kickolduser conflict.

 # 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.
-8. **User acceptance testing is MANDATORY before declaring work done.**
-   The agent performs implementation and technical validation (services
-   running, configs correct, APIs responding). The user performs UAT —
-   visually confirming dashboards render data, alerts deliver, tools are
-   usable. The agent MUST NOT set done-ratio to 100%, MUST NOT suggest
-   closing, and MUST NOT move to the next ticket until the user explicitly
-   accepts the work. "Technically wired but blank dashboard" is NOT done.
-9. **NEVER access a database directly if an API exists.** APIs are the
-   stable contract; databases change schemas without warning. If a tool
-   has an API, use it — exhaust all API endpoints, check the docs, try
-   alternative methods. Only fall back to direct DB access as a last
-   resort AND with explicit user approval for that specific instance.
-   Soon all DB access will route through a proxy under zero trust;
-   building API-first habits now ensures that transition is clean.
-
-### 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).
+**Top-level files:** [`README.md`](README.md) (project overview),
+[`STATUS.md`](STATUS.md) (living status, agent-maintained),
+[`docs/docmap.md`](docs/docmap.md) (documentation index). Everything else
+lives in subdirectories.

-- **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`
+- **Self-locating scripts**: All provisioning scripts derive their own
+  location via `BASH_SOURCE` and compute `PROJECT_ROOT_PATH` from it. Run
+  from anywhere.
+- **Local configs are the source of truth**: Files in
+  [`provisioning/ConfigFiles/`](provisioning/ConfigFiles/) are read with
+  `cat`/`cp`. Do NOT re-introduce `curl ${DL_ROOT}/...` downloads.
+- **Non-bash files**: Some files under `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.
+- **SSH in Crush**: Direct ssh/scp is blocked. Use
+  [`tests/remote.sh`](tests/remote.sh) or
+  [`dns-cluster-setup/remote-dns.sh`](dns-cluster-setup/remote-dns.sh).

 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.

+
+## Automatic Gardening Protocol
+
+**Docs and code must be kept in sync.** After any work session, an agent MUST:
+
+1. **Update [`STATUS.md`](STATUS.md)** — reflect completed work, new issues,
+   changed infrastructure state. This file is human read-only; agents own it.
+2. **Update [`docs/docmap.md`](docs/docmap.md)** — if a doc was added,
+   removed, or substantively changed, update the table and "Last Reviewed"
+   date.
+3. **Grep for stale paths** — `grep -rn 'old/path' --include='*.md'` after
+   any rename or restructure. Fix all references in the same commit.
+4. **Verify new docs are linked** — every new `.md` file must appear in
+   [`docs/docmap.md`](docs/docmap.md) and be linked from at least one other
+   doc.
+5. **If a new top-level directory was created, update ALL directory listings:**
+   - [`README.md`](README.md) → "Directory Structure" table
+   - [`AGENTS.md`](AGENTS.md) → "Repository Layout" code block
+   - [`AGENTS.md`](AGENTS.md) → "Key Scripts" table (if the directory has
+     an entrypoint script)
+   Missing any one of these is a protocol violation.
+6. **Self-audit before commit.** Before committing, run:
    ```
-   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.

-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

-
-## 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`.
+   grep -lE 'new_dir_name' README.md AGENTS.md docs/docmap.md STATUS.md
+   ```
+   Every new top-level directory must appear in all four files.

-## 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.

+## Current State: STABLE
+
+The merged PFVCluster repo is fully operational across provisioning, DNS
+infrastructure, Proxmox cluster ops, and k8s control plane.
+
+## Completed Work
+
+### Server Provisioning (validated on sectestbed-sandbox)
+- [x] SetupNewSystem.sh deploys end-to-end to rc=0 (Debian 13 trixie)
+- [x] Security hardening: SSH, SCAP-STIG, Wazuh, 2FA (SSH+Cockpit+Webmin)
+- [x] NTP: redundant pfv-netinfra-01/02 (192.168.3.252/253), synced stratum 3
+- [x] DNS resolv.conf: managed static file pointing at netinfra pair
+- [x] Test suite: 5 tests (framework, safe-download, 2fa, https, system-req)
+- [x] VM validation harness: git-based deploy + auto-rollback + guest-agent access
+
+### DNS Cluster (pfv-netinfra-01/02)
+- [x] Production Technitium config replicated from tailscale-router (read-only)
+- [x] 124 zones on both nodes (knel.net + reverse DNS)
+- [x] pfv-netinfra-01 = PRIMARY, pfv-netinfra-02 = SECONDARY
+- [x] Zone replication via rsync systemd timer (every 60s)
+- [x] Credentials + 2FA replicated identically to production
+- [x] Both LAN IPs resolve knel.net device names + recurse externally
+
+### Proxmox Cluster Ops
+- [x] 5 of 7 hosts fully performance-tuned (tsys1/3/6/7/9)
+- [x] Fleet audit complete (PROJECT.md has ground truth)
+- [ ] tsys4: blocked on PCIe NIC + RAM install
+- [ ] tsys5: blocked on 2nd ethernet cable + NVMe install
+- [ ] tsys2: pending rebuild from Win10 to Proxmox
+
+### Kubernetes Control Plane (k3s HA — LIVE)
+- [x] 3-node k3s HA control plane deployed: cnode1/2/3 (v1.36.2+k3s1, embedded etcd)
+- [x] **All traffic over Tailscale IPs** — no LAN IPs in node status or certs
+- [x] All 3 cnodes tainted `control-plane:NoSchedule` (zero user workloads)
+- [x] 13/13 health checks pass (verify.sh): nodes Ready, etcd quorum,
+  Tailscale IPs, CoreDNS, API server, workload isolation
+- [x] Scripts in `k8s/`: wipe, install-cp, join-servers, post-setup, verify
+- [x] Kubeconfig saved to `~/.kube/config.pfv-k8s` (gitignored, embedded certs)
+- [ ] Workers (wnodes) not yet joined to this cluster
+- [ ] Distro decision: **k3s chosen for regular R&D cluster**. Talos docs
+  preserved in `docs/k8s/` for future ITAR/classified cluster.
+
+### PDU Management (powerman on pfv-tsys1 — LIVE)
+- [x] Cyclades AlterPath PM10i (10 outlets) managed via powerman over serial
+- [x] USB-DB9 adapter (Prolific pl2303) with stable udev symlink
+  `/dev/cyclades-pm10`
+- [x] powermand listening on `127.0.0.1:10101` + Tailscale `100.121.189.98:10101`
+- [x] All 10 outlets defined as `outlet-1` through `outlet-10`
+- [x] Validated: outlet 10 cycled off → on (8/8 test checks passed)
+- [ ] Rename outlets to match physical devices (Friday onsite)
+
+### Console Management (ser2net + conman on pfv-tsys4 — LIVE)
+- [x] 7 network switch/router consoles managed via ser2net + conman
+- [x] **USB enumeration problem SOLVED:** udev rules pin each adapter by
+  ID_PATH (physical USB port topology) to stable `/dev/consoles/<name>`
+  symlinks that survive reboot regardless of enumeration order
+- [x] ser2net exposes all 7 consoles on TCP ports (2001-2007) bound to
+  **Tailscale IP only** (`100.70.77.93`)
+- [x] conman connects to TCP ports for logging + multiplexing (7 log
+  files active in `/var/log/conman/`)
+- [x] Both ser2net + conmand enabled via systemd (survive reboot)
+- [x] conmand systemd unit created (Debian package doesn't ship one)
+- [x] Old `/root/conmap` + manual `screen` workflow replaced
+
+### Repo Merge
+- [x] KNELServerBuild merged into PFVCluster (history preserved)
+- [x] Directory structure reorganized (provisioning/, tests/, perf/, docs/)
+- [x] All docs gardened: links fixed, stale refs removed, tailscale.md updated
+

+# Console Management (ser2net + conman)
+
+Network-accessible serial console management for all production network
+switches and routers, running on **pfv-tsys4** (storage server).
+
+## Architecture
+
+```
+USB-DB9 adapters → udev symlinks (/dev/consoles/<name>) → ser2net (TCP) → conman (logging + multiplexing)
+```
+
+ser2net owns the physical serial devices and exposes them on TCP ports
+bound to the **Tailscale interface only** (`100.70.77.93:200X`). conman
+connects to those TCP ports for session logging, output capture, and
+multi-user console sharing.
+
+**conman and ser2net do NOT share ports** — only one process can open a
+serial device at a time. ser2net owns the physical device; conman connects
+over TCP.
+
+## The USB Enumeration Problem (SOLVED)
+
+The 9 Prolific USB-to-DB9 adapters (`067b:2303`) on pfv-tsys4 have **no
+unique USB serial numbers** and get assigned `/dev/ttyUSB0-8` based on
+enumeration order, which shifts on every boot. This made the old
+`/root/conmap` + manual `screen` workflow break after every reboot.
+
+**Fix:** udev rules pin each adapter by its **ID_PATH** (physical USB port
+topology), which is stable across reboots regardless of enumeration order.
+Each adapter gets a named symlink in `/dev/consoles/` that never changes.
+
+The udev rules are generated from `mapping.txt`, which maps each adapter's
+ID_PATH to a console name and TCP port. To re-map after physically moving
+an adapter, update `mapping.txt` and re-run `setup.sh`.
+
+**Fallback:** if udev trigger doesn't create symlinks for already-discovered
+devices (common on first run), `setup.sh` creates them manually by matching
+ID_PATH. On subsequent boots, udev creates them automatically.
+
+## Port Assignments
+
+| TCP Port | Console Name | ID_PATH | Description |
+|----------|-------------|---------|-------------|
+| 2001 | pfv-core-sw01 | usb-0:1.5.4.4 | Dell PowerConnect 5448 (core switch) |
+| 2002 | pfv-tor3-mgmt | usb-0:1.6.3.1 | Rack 3 management TOR switch |
+| 2003 | pfv-tor3-stor | usb-0:1.6.3.3.2 | Rack 3 storage TOR switch |
+| 2004 | pfv-rrinfra-rtr | usb-0:1.6.3.3.1 | Cisco router (rrinfra) |
+| 2005 | pfv-r2-tor-top | usb-0:1.6.3.3.3 | Rack 2 top-of-rack switch |
+| 2006 | subodev-torsw | usb-0:1.5.4.1 | Suborbital device TOR switch |
+| 2007 | pfv-r2-sw | usb-0:1.6.3.2 | Rack 2 old Dell switch |
+
+All ports listen on the Tailscale IP (`100.70.77.93`).
+
+## Scripts
+
+| Script | Purpose |
+|--------|---------|
+| [`mapping.txt`](mapping.txt) | Source of truth: TCP port ↔ ID_PATH ↔ name ↔ baud |
+| [`generate-config.sh`](generate-config.sh) | Generates udev rules, ser2net.yaml, conman.conf from mapping.txt |
+| [`setup.sh`](setup.sh) | Full deploy: generate configs, create symlinks, restart services |
+| [`discover.sh`](discover.sh) | Read-only discovery of USB adapters, existing config, services |
+
+## Usage
+
+### Connect to a console
+
+**Primary method — conman client (with logging + multiplexing):**
+
+```bash
+# From any Tailscale-connected workstation:
+conman -d pfv-tsys4:7890 -f pfv-core-sw01     # connect to console
+conman -d pfv-tsys4:7890 -q                    # list all consoles
+```
+
+Escape sequence: `&.` to disconnect, `&?` for help.
+
+**Direct telnet (emergency only — conflicts with conman):**
+
+```bash
+# Direct telnet to ser2net works ONLY when conmand is stopped, because
+# conmand maintains persistent connections to all 7 TCP ports. Use:
+ssh pfv-tsys4 'systemctl stop conmand'
+telnet pfv-tsys4 2001                          # pfv-core-sw01
+ssh pfv-tsys4 'systemctl start conmand'        # restart when done
+```
+
+**Do NOT use telnet while conmand is running** — conmand will reconnect
+and kick your telnet session immediately ("Connection closed by foreign host").
+The correct workflow is conman client → conmand → ser2net → device.
+
+### Re-deploy after changing mapping.txt
+
+```bash
+PROX_HOST=pfv-tsys4 bash tests/remote.sh prox 'bash /root/console/setup.sh'
+```
+
+### Find the ID_PATH for a new adapter
+
+```bash
+PROX_HOST=pfv-tsys4 bash tests/remote.sh prox-file console/discover.sh
+```
+
+Then match the new adapter's ID_PATH to its physical location and add a line
+to `mapping.txt`.
+
+## Files on pfv-tsys4
+
+| File | Purpose |
+|------|---------|
+| `/etc/udev/rules.d/99-console-ports.rules` | Stable symlinks by ID_PATH |
+| `/etc/ser2net.yaml` | ser2net config (TCP ports → serial symlinks) |
+| `/etc/conman.conf` | conman config (CONSOLE entries between markers) |
+| `/etc/systemd/system/conmand.service` | systemd unit for conmand |
+| `/root/console/mapping.txt` | Copy of the source-of-truth mapping |
+| `/root/console/setup.sh` | Setup script (re-runnable) |
+| `/root/console/generate-config.sh` | Config generator |
+
+## Old workflow (replaced)
+
+The old `/root/conmap` file and manual `screen` sessions are no longer
+needed. The new setup is fully automated and survives reboots.

+ └──────────────────────────────────────────────────────────┘
+```
+
+### How clustering works
+
+Technitium uses standard DNS zone transfers (AXFR/IXFR) for primary/secondary
+replication, not a proprietary protocol:
+
+1. **Primary (01)** holds all zones as authoritative primary zones.
+2. **Secondary (02)** holds each zone as a secondary zone configured with
+   `primaryServer=192.168.3.252:5300`.
+3. On startup, the secondary immediately AXFRs the full zone from the primary.
+4. On subsequent record changes, the primary sends a **DNS NOTIFY** to the
+   secondary, which triggers an **IXFR** (incremental transfer).
+5. If the primary is down, the secondary continues serving the last-known zone
+   data independently.
+
+### Credentials and 2FA
+
+The production `auth.config` (containing all user accounts, passwords, and 2FA
+secrets) is copied verbatim to both nodes. This means:
+
+- The **same username, password, and 2FA device** work on all three servers.
+- The web console is at `http://<host>:5380/` on each node.
+- No credential changes are needed.
+
+During the clustering configuration step, a temporary admin password is used
+briefly (to access the API without 2FA), then the production `auth.config` is
+restored. See "Security notes" below.
+
+## Prerequisites
+
+- SSH key access to all hosts as `localuser` with passwordless sudo.
+- The `remote-dns.sh` wrapper must be able to reach all hosts via Tailscale FQDN.
+- Docker + Docker Compose on netinfra-01/02 (already installed).
+- The production Technitium on tailscale-router must be running.
+
+## Usage
+
+```bash
+cd dns-cluster-setup/
+
+# Step-by-step (recommended for first run):
+./setup.sh export      # 1. Export config from tailscale-router (READ-ONLY)
+./setup.sh deploy01    # 2. Deploy to netinfra-01 as primary
+./setup.sh deploy02    # 3. Deploy to netinfra-02 as secondary clone
+./setup.sh cluster     # 4. Configure clustering (01→02 zone transfers)
+./setup.sh verify      # 5. Run all verification tests
+
+# Or all at once:
+./setup.sh all
+```
+
+### Configuration overrides
+
+All defaults can be overridden via environment variables:
+
+| Variable | Default | Description |
+|---|---|---|
+| `PRIMARY_IP` | `192.168.3.252` | netinfra-01 LAN IP |
+| `SECONDARY_IP` | `192.168.3.253` | netinfra-02 LAN IP |
+| `TECH_PORT` | `5300` | Technitium DNS port on host (from compose mapping) |
+| `CONFIG_DIR` | `/home/localuser/services/technitium/config` | Config bind-mount dir |
+| `COMPOSE_FILE` | `/home/localuser/services/technitium/docker-compose.yml` | Compose file |
+| `TEMP_ADMIN_PW` | `KnelClusterSetup!2026` | Temp admin password (used only during clustering, then discarded) |
+
+## Scripts
+
+| Script | Purpose |
+|---|---|
+| `remote-dns.sh` | SSH/SCP chokepoint for all DNS host access (tsrouter, netinfra01, netinfra02, netboot, sandbox) |
+| `setup.sh` | Master orchestrator: export → deploy → cluster → verify |
+| `verify.sh` | Comprehensive 10-section verification suite |
+| `discover*.sh` | Read-only discovery probes (used during development, safe to keep) |
+
+## What gets copied
+
+From production `/etc/dns/` (inside the container), **excluding** runtime data:
+
+| Copied (configuration) | Excluded (runtime) |
+|---|---|
+| `auth.config` (users, passwords, 2FA) | `cache.bin` (DNS cache) |
+| `dns.config` (server settings) | `stats/` (query statistics) |
+| `webservice.config` (web console) | `logs/` (log files) |
+| `allowed.config` (zone transfer ACL) | |
+| `blocked.config` (blocked domains) | |
+| `blocklist.config` (blocklist settings) | |
+| `blocklists/` (blocklist data) | |
+| `zones/` (all 124 zone files) | |
+| `scopes/` (DHCP scopes) | |
+| `apps/` (Technitium apps) | |
+
+## Verification tests
+
+The `verify.sh` script runs 10 categories of tests:
+
+1. **Container health** — both Technitium containers are Up
+2. **API responds** — web console API is reachable on both nodes
+3. **Zone count** — primary matches production; secondary matches primary
+4. **Forward DNS** — known knel.net records resolve identically on both nodes
+5. **External DNS** — both nodes can resolve external domains (github.com)
+6. **Zone transfer (AXFR)** — secondary can AXFR knel.net from primary
+7. **Reverse DNS** — PTR zones have SOA records on both nodes
+8. **Production untouched** — container still running, zone count unchanged
+9. **Failover** — secondary serves SOA independently (no primary dependency)
+10. **Credentials** — `auth.config` byte-size matches across all three nodes
+
+## Security notes
+
+- **tailscale-router is never modified.** The only operation is `docker cp`
+  (read) to export the config. No writes, no restarts, no config changes.
+- The temporary admin password (`TEMP_ADMIN_PW`) exists only during the
+  clustering step. After configuration, the production `auth.config` (with 2FA)
+  is restored. The temp password is never persisted.
+- The export tarball (`.export/technitium-production-config.tar.gz`) contains
+  production credentials. It is in `.gitignore` and should be deleted after
+  setup: `rm -rf dns-cluster-setup/.export/`
+- Each node's existing config is backed up to `config.backup-<timestamp>` before
+  replacement, so the change is reversible.
+
+## Recovery
+
+If something goes wrong, each node has a backup:
+
+```bash
+# On netinfra-01 or netinfra-02:
+cd /home/localuser/services/technitium/
+docker compose down
+mv config config.failed
+mv config.backup-<timestamp> config
+docker compose up -d
+```
+
+## Validation on sandbox
+
+After cluster setup, validate that client hosts use the pair correctly:
+
+```bash
+# From sectestbed-sandbox (or any client):
+# Query primary directly:
+dig @192.168.3.252 pfv-netinfra-01.knel.net
+
+# Query secondary directly:
+dig @192.168.3.253 pfv-netinfra-01.knel.net
+
+# Both should return the same answer.
+```
+
+The KNELServerBuild provisioning code (`provisioning/ConfigFiles/NTP/ntp.conf`
+and `provisioning/ConfigFiles/Resolv/resolv.conf`) points clients at both
+servers for DNS and NTP redundancy. See `docs/server-build/tailscale.md` for the
+full DNS architecture analysis.

+# AI Review: KNELServerBuild (PFVCluster) Project
+
+## Executive Summary
+
+The KNELServerBuild project is a comprehensive Infrastructure-as-Code (IaC) solution designed for provisioning Linux servers within the TSYS Group environment. The project implements a fetch-and-apply framework that automates the setup and hardening of server systems, incorporating security, monitoring, and operational components.
+
+## Project Overview
+
+The PFVCluster project is a shell-based automation framework that provisions Linux servers with:
+- Security hardening (SSH, 2FA, Wazuh, STIG compliance)
+- Operational monitoring (LibreNMS, cockpit, SNMP)
+- System packages and configurations for enterprise operations
+- Network discovery and management capabilities
+
+## Architecture and Structure
+
+### Key Components
+- **provisioning/**: Main setup and configuration scripts
+- **Project-ConfigFiles/**: Configuration variables and parameters
+- **Project-Includes/**: Reusable shell functions and utilities
+- **tests/**: Comprehensive testing framework
+- **Modules/**: Functional modules for security, operations, etc.
+- **vendor/**: External dependencies and frameworks
+
+### Core Workflow
+The `SetupNewSystem.sh` orchestrates:
+1. Preflight checks and environment validation
+2. Package installation and system updates
+3. Service configuration and hardening
+4. Security implementation (SSH, Wazuh, 2FA)
+5. Operational monitoring setup
+
+## Strengths
+
+### 1. Comprehensive Testing Framework
+- Well-structured testing with unit, integration, security, and validation categories
+- Clear documentation and usage instructions
+- JSON reporting for CI/CD integration
+
+### 2. Security-First Approach
+- Multiple layers of security hardening (SSH, 2FA, audit agents)
+- STIG compliance for government/hybrid environments
+- Proper permission management and configuration validation
+
+### 3. Modular Architecture
+- Separated concerns into functional modules
+- Reusable functions and components
+- Clear separation between framework and project-specific code
+
+### 4. Operational Readiness
+- Built-in monitoring and alerting
+- System performance optimization
+- Network discovery and management tools
+
+### 5. Cross-Platform Considerations
+- Detection for different hardware types (physical, virtual, Raspberry Pi)
+- Distribution-specific handling
+- Environment-aware configurations
+
+## Areas for Improvement
+
+### 1. Documentation Completeness
+- README mentions usage but lacks detailed architecture overview
+- Missing troubleshooting and recovery procedures
+- Limited guidance for extending/adding new modules
+
+### 2. Security and Secrets Management
+- Configuration files may expose hardcoded credentials or tokens
+- No clear secrets management strategy
+- Download URLs and endpoints are hardcoded in scripts
+
+### 3. Error Handling and Resilience
+- While scripts have basic error handling, recovery mechanisms are limited
+- No rollback capabilities for failed installations
+- Some operations may fail silently
+
+### 4. Scalability and Performance
+- Scripts execute sequentially without parallelization
+- No caching mechanisms for downloads
+- Limited handling for high-latency networks
+
+### 5. Configuration Management
+- Configuration values scattered across multiple files
+- No centralized configuration management
+- Difficult to customize for different environments
+
+## Recommendations
+
+### 1. Enhance Security Practices
+- Implement secrets management (HashiCorp Vault, AWS Secrets Manager, etc.)
+- Add configuration validation before applying changes
+- Implement digital signature verification for downloaded content
+- Add security scanning of packages before installation
+
+### 2. Improve Testing Coverage
+- Add end-to-end tests for complete deployment scenarios
+- Implement performance benchmarks
+- Add security validation tests
+- Include tests for different hardware configurations
+
+### 3. Add Monitoring and Observability
+- Implement deployment success/failure metrics
+- Add progress tracking for long-running operations
+- Include health checks post-deployment
+- Add rollback mechanisms for failed deployments
+
+### 4. Refactor for Maintainability
+- Centralize configuration management
+- Abstract environment-specific variables
+- Implement plugin architecture for new modules
+- Add proper logging and audit trails
+
+### 5. Enhance Usability
+- Add dry-run functionality for testing changes
+- Provide rollback/recovery procedures
+- Add interactive mode for new users
+- Implement configuration templates
+
+## Technical Debt Assessment
+
+### High Priority
+- Centralized configuration management
+- Secrets handling and security
+- Error recovery and rollback mechanisms
+
+### Medium Priority
+- Parallel execution of independent operations
+- Caching for downloaded packages/configs
+- Improved logging and monitoring
+
+### Low Priority
+- Code modernization (consider newer shell features)
+- Migration to configuration management tools (Ansible/Terraform)
+
+## Conclusion
+
+The PFVCluster project represents a solid foundation for automated server provisioning with good security practices and testing. However, there are significant opportunities to improve security, maintainability, and operational resilience. Prioritizing security improvements and configuration management would provide the greatest value to the project's stability and long-term viability.
+
+The modular architecture and comprehensive testing framework provide a strong foundation for future enhancements and improvements.

+# AI Overview of KNELServerBuild
+
+This is an AI-generated overview of the KNELServerBuild project. The analysis is based on a read-only review of the project's files.
+
+## Project Overview
+
+The KNELServerBuild project is an Infrastructure as Code (IAC) repository for provisioning and configuring Linux servers. It is based on a collection of bash scripts that automate the installation of packages, configuration of services, and security hardening of the system. The project is designed to be used with the `FetchApply` tool, which is not included in this repository.
+
+The main entry point of the project is the `provisioning/SetupNewSystem.sh` script. This script performs the following actions:
+
+*   **Initializes the environment:** Sets up project paths and sources a shell framework (`KNELShellFramework`) and project-specific includes.
+*   **Installs packages:** Installs a wide range of packages, including monitoring agents (check_mk, snmp), security tools (auditd, aide, lynis, clamav), administration tools (cockpit, webmin), and common utilities (tmux, vim, zsh).
+*   **Configures services:** Configures various services like Postfix for email, `rsyslog` for system logging, `snmpd` for monitoring, `lldpd` for network discovery, and `cockpit`.
+*   **Security Hardening:** It runs a series of security hardening scripts from `Modules/Security`, including `secharden-ssh.sh`, `secharden-wazuh.sh`, `secharden-2fa.sh`, and `secharden-scap-stig.sh`.
+*   **OAM:** It runs an OAM (Operations, Administration, and Maintenance) script for LibreNMS.
+*   **Conditional Logic:** It has conditional logic to apply different configurations based on whether the host is a physical Dell server, a virtual machine (KVM or Hyper-V), or a Raspberry Pi.
+
+## What I Like
+
+*   **Well-structured:** The project is well-structured, with separate directories for code, configuration files, documentation, and tests. This makes it easy to understand and maintain.
+*   **Modularity:** The use of modules for different functionalities (e.g., security hardening, OAM) is a good practice. It allows for easy extension and modification of the project.
+*   **Comprehensive:** The project covers a wide range of aspects of server provisioning, from package installation to security hardening.
+*   **Conditional Logic:** The use of conditional logic to adapt the configuration to different environments is a good feature.
+*   **Good commenting:** The scripts are generally well-commented, which makes them easier to understand.
+
+## Areas for Improvement
+
+*   **Error Handling:** The scripts could benefit from more robust error handling. For example, the `SetupNewSystem.sh` script uses `set -e` to exit on error, but it does not have any specific error handling logic.
+*   **Idempotency:** The scripts are not fully idempotent. For example, some of the `curl` commands will re-download files even if they already exist. This could be improved by adding checks to see if the files already exist.
+*   **Testing:** The project has a `Project-Tests` directory, but it is not clear how the tests are run or what they cover. The testing framework could be improved to provide more comprehensive coverage of the project's functionality.
+*   **Secrets Management:** The scripts contain some hardcoded secrets, such as the `relayhost` for Postfix. These secrets should be managed using a secrets management tool like HashiCorp Vault or AWS Secrets Manager.
+*   **Configuration Management:** The project uses a collection of shell scripts to manage the configuration of the system. While this works, it can be difficult to manage and maintain in the long run. A configuration management tool like Ansible, Puppet, or Chef would be a better choice for this task. The project already installs `ansible-core`, so it would be a natural progression to move the logic to Ansible playbooks.
+*   **Documentation:** The project has some documentation, but it could be improved. For example, the `README.md` file could provide more information on how to use the project and how to contribute to it.
+
+## Recommendations
+
+*   **Improve Error Handling:** Add more robust error handling to the scripts to make them more reliable.
+*   **Improve Idempotency:** Make the scripts more idempotent to avoid unnecessary re-downloads and re-configurations.
+*   **Improve Testing:** Implement a more comprehensive testing framework to ensure the quality of the project.
+*   **Use a Secrets Management Tool:** Use a secrets management tool to manage the secrets in the project.
+*   **Use a Configuration Management Tool:** Use a configuration management tool like Ansible to manage the configuration of the system.
+*   **Improve Documentation:** Improve the documentation of the project to make it easier to use and contribute to.
+
+Overall, the KNELServerBuild project is a good starting point for an IAC repository. It is well-structured and covers a wide range of aspects of server provisioning. However, there are some areas where it could be improved. By addressing the areas for improvement, the project can be made more robust, reliable, and maintainable.

+# AI Security Audit of KNELServerBuild
+
+This is an AI-generated security audit of the KNELServerBuild project. The analysis is based on a read-only review of the project's files.
+
+## Summary of Findings
+
+The KNELServerBuild project has a good security posture overall, but there are a few areas that could be improved. The most significant finding is the presence of SSH authorized keys in the repository. This is a security risk, as it allows anyone with access to the repository to know which public keys are authorized to access the servers.
+
+### High-Risk Findings
+
+*   **SSH Authorized Keys in Repository:** The `provisioning/ConfigFiles/SSH/AuthorizedKeys` directory contains SSH authorized keys for the `localuser` and `root` users. This is a security risk, as it allows anyone with access to the repository to know which public keys are authorized to access the servers.
+
+### Medium-Risk Findings
+
+*   **Hardcoded Hostnames:** The scripts contain several hardcoded hostnames for services like Postfix, NTP, syslog, and Wazuh. This is not a direct security risk, but it does represent a configuration management issue. If any of these hostnames change, they will need to be updated in multiple places.
+
+### Low-Risk Findings
+
+*   **Potential for Password on Command Line:** The `provisioning/Agents/librenms/mysql.sh` script has a `--pass` argument for a MySQL password. This is a potential security risk if the password is provided on the command line, as it could be logged in the shell history.
+
+## Recommendations
+
+*   **Remove SSH Authorized Keys from Repository:** The SSH authorized keys should be removed from the repository and managed using a secrets management tool like HashiCorp Vault or AWS Secrets Manager.
+*   **Use Variables for Hostnames:** The hardcoded hostnames should be replaced with variables that are defined in a central configuration file. This will make it easier to update the hostnames if they change.
+*   **Avoid Passwords on Command Line:** The `provisioning/Agents/librenms/mysql.sh` script should be modified to avoid passing the MySQL password on the command line. For example, the script could prompt the user for the password or read it from a configuration file.
+
+Overall, the KNELServerBuild project is a good starting point for an IAC repository. By addressing the security risks identified in this audit, the project can be made more secure and reliable.

+
+### Medium Priority (Operational)
+5. **Testing Framework:** Add integration tests for provisioning workflows
+6. **Documentation Enhancement:** Expand security considerations and deployment procedures
+7. **Configuration Validation:** Add pre-deployment validation of system requirements
+8. **Rollback Capability:** Implement configuration backup and rollback mechanisms
+
+### Low Priority (Quality of Life)
+9. **Error Recovery:** Enhanced error recovery and partial deployment resumption
+10. **Monitoring Integration:** Centralized logging and deployment status reporting
+11. **User Interface:** Consider web-based deployment dashboard for non-technical users
+
+## Risk Assessment 📊
+
+**Overall Risk Level:** Low-Medium ⬇️ (Reduced from Medium-Low)
+
+The repository contains well-architected defensive security tools with strong error handling and modular design. **Major security improvement:** The insecure `curl | bash` deployment method has been replaced with git-based deployment. Remaining concerns are primarily around hardening the provisioning scripts themselves rather than the deployment method.
+
+**Recommendation:** Continue addressing remaining security issues (HTTPS enforcement, secrets management) but the critical deployment risk has been mitigated. The codebase is much safer for production use.
+
+## Update Summary (July 14, 2025)
+
+**✅ Resolved Issues:**
+- Insecure deployment method replaced with git clone approach
+- README.md updated with project management and community links
+- Deployment security risk significantly reduced
+- All HTTP URLs converted to HTTPS (Dell OMSA, Proxmox, Apache sources)
+
+**🔄 Remaining Priorities:**
+1. ~~HTTPS enforcement for internal downloads~~ ✅ **RESOLVED:** All HTTP URLs converted to HTTPS
+2. Secrets management implementation
+3. Script integrity verification
+4. SSH key rotation from repository
+
+## Files Reviewed
+
+- 32 shell scripts across Framework-Includes, Project-Includes, and ProjectCode directories
+- Configuration files for SSH, SNMP, logging, and system services
+- Security modules for hardening, authentication, and monitoring
+- Documentation and framework configuration files
+
+## Next Steps
+
+See `charles-todo.md` and `claude-todo.md` for detailed action items prioritized for human operators and AI assistants respectively.

+# Charles TODO - PFVCluster Security Improvements
+
+**Priority Order:** High → Medium → Low  
+**Target:** Address security vulnerabilities and operational improvements
+
+## 🚨 HIGH PRIORITY (Security Critical)
+
+### ✅ 1. Replace Insecure Deployment Method - RESOLVED
+**Previous Issue:** `curl https://dl.knownelement.com/KNEL/FetchApply/SetupNewSystem.sh | bash`
+**Status:** Fixed in README.md - now uses secure git clone approach
+**Current Method:** `git clone this repo` → `cd PFVCluster/provisioning` → `bash SetupNewSystem.sh`
+
+**Remaining considerations:**
+- Consider implementing GPG signature verification for tagged releases
+- Add cryptographic checksums for external downloads within scripts
+
+### ✅ 2. Enforce HTTPS for All Downloads - RESOLVED
+**Previous Issue:** HTTP URLs in Dell OMSA and some repository setups
+**Status:** All HTTP URLs converted to HTTPS across:
+  - `provisioning/Dell/Server/omsa.sh` - Ubuntu archive and Dell repo URLs
+  - `provisioning/legacy/prox7.sh` - Proxmox download URLs
+  - `provisioning/Modules/RandD/sslStackFromSource.sh` - Apache source URLs
+
+**Remaining considerations:**
+- SSL certificate validation is enabled by default in wget/curl
+- Consider adding retry logic for certificate failures
+
+### 3. Implement Secrets Management

+- Create secure key distribution mechanism
+- Implement key rotation procedures
+- Add environment variable support for sensitive data
+
+**Files to secure:**
+- `provisioning/ConfigFiles/SSH/AuthorizedKeys/` (entire directory)
+- Hard-coded hostnames in various scripts
+
+## 🔶 MEDIUM PRIORITY (Operational Security)
+
+### 4. Add Script Integrity Verification
+**Action Required:**
+- Generate SHA256 checksums for all scripts
+- Create checksum verification function in Framework-Includes
+- Add signature verification for external downloads
+- Implement rollback capability on verification failure
+
+### 5. Enhanced Error Recovery
+**Action Required:**
+- Add state tracking for partial deployments
+- Implement resume functionality for interrupted installations
+- Create system restoration points before major changes
+- Add dependency checking before module execution
+
+### 6. Security Testing Framework
+**Action Required:**
+- Create integration tests for security configurations
+- Add compliance validation (CIS benchmarks, STIG)
+- Implement automated security scanning post-deployment
+- Create test environments for validation
+
+### 7. Configuration Validation
+**Action Required:**
+- Add pre-flight checks for system compatibility
+- Validate network connectivity to required services
+- Check for conflicting software before installation
+- Verify sufficient disk space and system resources
+
+## 🔹 LOW PRIORITY (Quality Improvements)
+
+### 8. Documentation Enhancement
+**Action Required:**
+- Create detailed security architecture documentation
+- Add troubleshooting guides for common issues
+- Document security implications of each module
+- Create deployment runbooks for different environments
+
+### 9. Monitoring and Alerting
+**Action Required:**
+- Add deployment success/failure reporting
+- Implement centralized logging for all installations
+- Create dashboards for deployment status
+- Add alerting for security configuration drift
+
+### 10. User Experience Improvements
+**Action Required:**

+# Claude TODO - TSYS PFVCluster Automation Tasks
+
+**Purpose:** Actionable items optimized for AI assistant implementation  
+**Priority:** Critical → High → Medium → Low
+
+## 🚨 CRITICAL (Immediate Security Fixes)
+
+### ✅ RESOLVED: Secure Deployment Method
+**Previous Issue:** `curl | bash` deployment method  
+**Status:** Fixed in README.md - now uses `git clone` + local script execution
+
+### ✅ RESOLVED: Replace HTTP URLs with HTTPS
+**Files modified:**
+- `provisioning/Dell/Server/omsa.sh` - Converted 11 HTTP URLs to HTTPS (Ubuntu archive, Dell repo)
+- `provisioning/legacy/prox7.sh` - Converted 2 HTTP URLs to HTTPS (Proxmox downloads)
+- `provisioning/Modules/RandD/sslStackFromSource.sh` - Converted 3 HTTP URLs to HTTPS (Apache sources)
+
+**Status:** All HTTP URLs in active scripts converted to HTTPS. Only remaining HTTP references are in comments and LibreNMS agent files (external dependencies).
+
+### TASK-002: Add Download Integrity Verification
+**Create new function in:** `Framework-Includes/VerifyDownload.sh`
+**Function to implement:**
+```bash
+function verify_download() {

+    local output_file="$3"
+    
+    curl -fsSL "$url" -o "$output_file"
+    local actual_hash=$(sha256sum "$output_file" | cut -d' ' -f1)
+    
+    if [ "$actual_hash" != "$expected_hash" ]; then
+        print_error "Hash verification failed for $output_file"
+        rm -f "$output_file"
+        return 1
+    fi
+    print_info "Download verified: $output_file"
+}
+```
+
+### TASK-003: Create Secure Deployment Script

+2. Modify secharden-ssh.sh to fetch keys from secure source
+3. Add key validation before deployment
+
+### TASK-005: Add Secrets Management Framework
+**Create:** `Framework-Includes/SecretsManager.sh`
+**Functions to implement:**
+```bash
+function get_secret() { }           # Retrieve secret from vault

+### TASK-006: Enhanced Preflight Checks
+**Modify:** `Framework-Includes/PreflightCheck.sh`
+**Add checks for:**
+- Network connectivity to required hosts
+- Disk space requirements
+- Existing conflicting software
+- Required system capabilities
+
+## 🔹 MEDIUM (Operational Improvements)
+
+### TASK-007: Add Configuration Backup
+**Create:** `Framework-Includes/ConfigBackup.sh`
+**Functions:**
+```bash
+function backup_config() { }        # Create timestamped backup
+function restore_config() { }       # Restore from backup

+- Dependency analysis output
+
+## Implementation Order for Claude
+
+**Updated Priority After Security Fix (July 14, 2025):**
+1. **Start with TASK-001** (HTTPS enforcement - simple find/replace operations)
+2. **Create framework functions** (TASK-002, TASK-005, TASK-007)
+3. **Enhance existing modules** (TASK-004, TASK-006)
+4. **Add operational features** (TASK-008, TASK-009)
+5. **Improve user experience** (TASK-010, TASK-011, TASK-012)
+
+**Note:** Major deployment security risk resolved - remaining tasks focus on hardening internal operations.
+
+## File Location Patterns
+
+- **Framework components:** `Framework-Includes/*.sh`
+- **Security modules:** `provisioning/Modules/Security/*.sh`
+- **Configuration files:** `provisioning/ConfigFiles/*/`
+- **Main entry point:** `provisioning/SetupNewSystem.sh`
+
+## Testing Strategy
+
+For each task:
+1. Create backup of original files
+2. Implement changes incrementally
+3. Test with `bash -n` for syntax validation
+4. Verify functionality with controlled test runs
+5. Document changes made
+
+## Error Handling Requirements
+
+All new functions must:
+- Use `set -euo pipefail` compatibility
+- Integrate with existing error handling framework
+- Log errors to `$LOGFILENAME`
+- Return appropriate exit codes
+- Clean up temporary files on failure

+## Agent Gardening Protocol
+
+When making changes to this repo, agents MUST:
+
+1. **Update [`../STATUS.md`](../STATUS.md)** if the work changes infrastructure
+   state, completes/starts a task, or discovers a new issue.
+2. **Update this file (`docmap.md`)** if a doc is added, removed, or has a
+   substantive content change. Update the "Last Reviewed" date.
+3. **Verify cross-references** — any new `.md` file must be linked from at
+   least one existing doc or this map.
+4. **Check for stale paths** — after any directory rename or file move,
+   `grep -rn 'old/path' --include='*.md'` and fix all references.
+5. **Keep code and docs in sync** — if you change a script's interface,
+   behavior, or location, update every doc that references it in the same
+   commit.

+
+### Design principles
+
+1. **LAN-only cluster nodes.** Zero internet egress from cnodes/wnodes.
+   Strongest posture for ITAR/classified.
+2. **Admin via Tailscale subnet router.** Existing `tailscale-router` VM
+   advertises the cluster LAN subnet. Operator reaches Talos API from
+   anywhere.
+3. **Local-first storage.** Cnodes boot from local disk (no NFS dependency
+   for etcd). Workers boot from local disk where available; NFS for bulk
+   data only.
+4. **Per-tenant vcluster.** Workload isolation via virtual clusters on top
+   of the Talos host cluster.
+5. **OIDC everywhere.** Talos API and Kubernetes API both trust Keycloak
+   tokens. No long-lived static credentials for humans.
+
+---
+
+## 2. Control Plane
+
+### 2.1 Recommendation: 3 cnodes (down from 5)
+
+| Option | Quorum | Failure tolerance | etcd write cost | Resource cost |
+|--------|--------|-------------------|-----------------|---------------|
+| **3 cnodes** (recommended) | 2 of 3 | Tolerates **1** failure | Lower (faster commits) | 3 × (2c/4GB/32GB) = 6c / 12GB |
+| 5 cnodes (current plan) | 3 of 5 | Tolerates **2** failures | Higher | 5 × (2c/4GB/32GB) = 10c / 20GB |
+
+For a solo-operated R&D cluster, **3 cnodes is the HA standard**. The
+failure-tolerance jump from 1→2 rarely justifies the doubled etcd write
+quorum and the extra 4GB/2c per cnode. The 2 freed VM slots (and their
+host capacity) are better spent on tenant worker allocations.
+
+**Caveat:** if your ITAR/classified accreditation counsel mandates 2-failure
+tolerance on the control plane, keep 5. Otherwise 3.
+
+### 2.2 Cnode placement
+
+Per [`../proxmox/K8S.md`](../proxmox/K8S.md) §4.3, cnodes should use
+**local-lvm boot disks** so etcd has no NFS dependency. Concrete placement:
+
+| cnode | Host | Boot disk | Type | Why |
+|-------|------|-----------|------|-----|
+| cnode1 | tsys9 | local-lvm (PNY CS900 SSD) | LOCAL-SSD | Fastest available for etcd. |
+| cnode2 | tsys9 | local-lvm (PNY CS900 SSD) | LOCAL-SSD | Same host, different disk OK (host failure is the failure domain, not disk). |
+| cnode3 | tsys1 | local-lvm (HDD) | LOCAL-HDD | Host diversity. Slower than SSD but no NFS hop. |
+
+**Quorum survival:**
+
+| Failure | cnodes lost | Quorum OK? |
+|---------|-------------|------------|
+| tsys9 host dies | cnode1 + cnode2 | NO (1 of 3) — would need 4th cnode elsewhere, or accept this risk. |
+| tsys1 host dies | cnode3 | YES (2 of 3) |
+| Any storage server dies | 0 | YES (3 of 3) — local disks unaffected |
+
+**Refinement:** putting both SSD cnodes on tsys9 means tsys9 host failure
+loses quorum. Alternative: spread cnodes across 3 different hosts. See
+"open question" at end of this section.
+
+### 2.3 Machine config strategy
+
+Talos nodes are configured by **machine configs** (YAML). Two flavors:
+
+- **`controlplane.yaml`** — for cnodes. Enables etcd, scheduler,
+  controller-manager, API server.
+- **`worker.yaml`** — for wnodes. Joins cluster, runs kubelet + containerd.
+
+Strategy for this cluster:
+
+1. **One shared `talosconfig`** (client identity) — stored in 1Password
+   and in the Proxmox Backup Server (PBS) encrypted backup target.
+2. **Per-node machine config patches** — small patches on top of the base
+   `controlplane.yaml` / `worker.yaml` for node-specific settings:
+   - Hostname
+   - Network interface + IP (DHCP or static — recommend static for cnodes)
+   - Schematic image digest (pinned Talos version)
+   - System extensions (e.g., `tailscale` — only if running Pattern A
+     instead of recommended Pattern C)
+3. **All machine configs in Git** under a future `k8s/talos-configs/`
+   directory. Secrets are templated in at apply-time from 1Password / sops.
+
+```mermaid
+flowchart LR
+    BASE[base controlplane.yaml] --> PATCH1[patch: cnode1]
+    BASE --> PATCH2[patch: cnode2]
+    BASE --> PATCH3[patch: cnode3]
+    BASEW[base worker.yaml] --> PATCHW[patch: per-wnode]
+    PATCH1 --> APPLY1[talosctl apply]
+    PATCH2 --> APPLY2[talosctl apply]
+    PATCH3 --> APPLY3[talosctl apply]
+    PATCHW --> APPLYW[talosctl apply]
+```
+
+### 2.4 Open question: cnode host spread
+
+If you accept "tsys9 failure = quorum loss" as a tolerable risk (solo R&D
+cluster, tsys9 is brand-new hardware, single digit annual failure
+probability), the layout in §2.2 is fine.
+
+If not, alternative spread across 3 hosts:
+
+| cnode | Host | Boot disk |
+|-------|------|-----------|
+| cnode1 | tsys9 | local-lvm SSD |
+| cnode2 | tsys1 | local-lvm HDD |
+| cnode3 | tsys3 | local-lvm NVMe |
+
+tsys3's local-lvm is **349 GB Samsung PM961 NVMe** (per
+[`../proxmox/PROJECT.md`](../proxmox/PROJECT.md) §3.3) — currently unused,
+would make an excellent etcd disk.
+
+**This 3-host spread survives any single host failure with quorum intact.
+Recommended.**

+
+### 3.2 Address plan (suggested)
+
+Reserve a small contiguous block in the residence LAN for cluster nodes:
+
+| Role | Range | Count |
+|------|-------|-------|
+| Cnodes | `192.168.3.31-33` | 3 |
+| Wnodes | `192.168.3.41-49` | up to 9 (1 per Proxmox host + spare) |
+| Bastion | existing `tailscale-router` | 1 |
+| Registry | `192.168.3.50` | 1 (Harbor) |
+
+**Static IPs are strongly recommended for cnodes** (etcd cluster membership
+is hostname-based; stable IPs make `talosctl` targeting simple). Workers
+can DHCP.
+
+### 3.3 Firewall posture
+
+Each cnode/wnode has:
+
+- **Ingress** from LAN: TCP 50000 (Talos API), TCP 6443 (Kubernetes API on
+  cnodes only), plus CNI ports (varies by CNI — see §4).
+- **Ingress** from Tailscale: none (cluster nodes are not on Tailscale).
+- **Egress:** LAN-only. Block all RFC1918-external traffic at the perimeter
+  firewall for these IPs. ITAR workloads must not be able to phone home.
+
+The bastion runs Tailscale and forwards TCP 50000/6443 to cluster nodes
+via the subnet route.
+
+---
+
+## 4. CNI: Cilium
+
+**Recommendation: Cilium** (eBPF-based CNI).
+
+| Property | Why it matters here |
+|----------|---------------------|
+| **NetworkPolicy** (incl. L7) | Per-tenant isolation rules in vclusters. |
+| **Node-to-node encryption** | WireGuard-based IPSec replacement. All inter-node pod traffic is encrypted on the wire. **Important for ITAR tenants.** |
+| **Hubble** | Observable flows — forensic record of which pod talked to which. Useful for compliance evidence. |
+| **No kube-proxy** | Cilium replaces kube-proxy with eBPF. Smaller attack surface on each node. |
+| **Talos integration** | First-class. Talos docs document the install path. |
+
+Cilium is deployed via Helm after cluster bootstrap. Node-to-node encryption
+enabled. Default-deny NetworkPolicy applied per namespace.
+
+---
+
+## 5. Identity and Trust
+
+### 5.1 Trust flow
+
+```mermaid

+    autonumber
+    participant Human as Operator
+    participant TAIL as Tailscale
+    participant BAST as Bastion

+    K8S->>KC: Validate token (introspection)
+    KC-->>K8S: Valid + claims
+    K8S-->>Human: Authorized response
+```
+
+### 5.2 Two distinct identity layers
+
+| Layer | Mechanism | Audience |
+|-------|-----------|----------|
+| **Talos API** (node ops) | Mutual TLS with client certificate generated from the Talos secrets bundle. | Operators (automation + humans). |
+| **Kubernetes API** (kubectl) | OIDC bearer token from Keycloak. RBAC maps group claims → ClusterRole. | Humans. Service accounts use projected tokens (no OIDC). |
+
+The **Talos secrets bundle** is the root of trust for the cluster. Lose it
+and you cannot operate the cluster; an attacker with it owns the cluster.
+Storage:
+
+1. **Primary:** 1Password (or equivalent) — operator-accessible.
+2. **Backup:** PBS encrypted backup target on tsys4 (existing infra).
+3. **NOT in Git.** Machine configs go in Git; secrets stay out.
+
+### 5.3 Keycloak client configuration
+
+On Cloudron-hosted Keycloak, register a client `pfv-k8s-talos`:
+
+- **Authorization Code + PKCE flow** (no implicit, no password).
+- **Redirect URIs:** `http://localhost:8000` (kubectl oidc-login) + Sidero
+  Omni/Rancher URLs if/when those are added.
+- **Group claims:** `k8s-admin`, `k8s-readonly`, `k8s-tenant-itar`,
+  `k8s-tenant-rackrental`, etc. These map to Kubernetes RBAC `ClusterRoleBinding`.
+
+---
+
+## 6. Tenant Isolation (vcluster)
+
+### 6.1 Why vcluster
+
+[vcluster](https://www.vcluster.com/) runs a **virtual Kubernetes control
+plane** (API server, scheduler, controller-manager, etcd) inside a namespace
+of the host cluster. Tenant workloads run on the host's worker nodes but
+are isolated by:
+
+- Separate API server (tenant cannot see host cluster objects).
+- Separate RBAC and admission control.
+- Separate network policies (per-namespace).
+- Separate resource quotas.
+
+This aligns with the user's per-tenant plan from
+[`../proxmox/K8S.md`](../proxmox/K8S.md) §1.
+
+### 6.2 Tenant registry
+
+| Tenant | Compliance | Workload example | vcluster name |
+|--------|-----------|------------------|---------------|
+| RackRental | None (internal R&D) | containerlab topology tests | `vc-rackrental` |
+| Suborbital non-ITAR | EAR/ITAR-aware but unclassified | Payload telemetry processing | `vc-suborbital-open` |
+| Suborbital ITAR | **ITAR-controlled** | Firmware build for USML items | `vc-suborbital-itar` |
+| Starting Line Productions | Commercial | Customer media pipeline | `vc-slp` |

+    class NS_SI,API_SI itar
+```
+
+### 6.3 ITAR enforcement at host layer
+
+For the ITAR tenant (`vc-suborbital-itar`), enforce additional host-layer
+controls:
+
+- **Node taint** `workload=itar:NoSchedule` on worker nodes dedicated to
+  ITAR workloads (subset of wnodes, marked in node labels).
+- **NetworkPolicy** default-deny egress for the `vc-suborbital-itar`
+  namespace. Allow only explicit destinations (registry, NFS for ITAR
+  data tier, Keycloak).
+- **Storage isolation:** ITAR PVCs target a dedicated NFS export (e.g.,
+  `D3-itar` on tsys5) that no other tenant can mount.
+- **Audit:** Hubble flows + auditd on the host worker nodes capture all
+  access to ITAR data.
+
+Rancher (or Sidero Omni) sits above this, presenting each tenant's
+vcluster as a separate "cluster" in its UI, with Keycloak SSO gating
+access per tenant group claim.
+
+---
+
+## 7. Storage Integration
+
+Per [`../proxmox/K8S.md`](../proxmox/K8S.md) §6. Three StorageClasses:
+
+| StorageClass | Provisioner | Backing | Speed | Use |
+|--------------|------------|---------|-------|-----|
+| `local-fast` | local-path | wnode local disk (NVMe/SSD/HDD depending on host) | 100-3500 MB/s | Container runtime, scratch, ephemeral |
+| `nfs-hdd` | nfs.csi.k8s.io | tsys4 D2/D5, tsys5 S1-S4 | 80-120 MB/s | Bulk data, weather/GIS datasets |
+| `nfs-ssd` | nfs.csi.k8s.io | tsys5 D3, tsys5 T5-SSD | 200-400 MB/s | Latency-sensitive persistent data |
+
+### 7.1 CSI driver notes
+
+- **NFS CSI:** [`csi-driver-nfs`](https://github.com/kubernetes-csi/csi-driver-nfs)
+  (CNCF sandbox). Deploys via Helm. Each StorageClass points at a specific
+  NFS server + base export path.
+- **local-path:** Rancher Local Path Provisioner. Single-binary, deploys
+  with one manifest. Uses wnode's kubelet root dir.
+
+### 7.2 ITAR data isolation
+
+The ITAR tenant should target a dedicated NFS export, not shared
+`nfs-hdd`. Recommended:
+
+- Allocate `S4` on tsys5 (currently 99% empty, 435 GB free) as
+  `nfs-itar` StorageClass. Mountable only from `vc-suborbital-itar`
+  namespace via RBAC + NetworkPolicy.
+
+---
+
+## 8. Local Image Registry
+
+### 8.1 Recommendation: Harbor on D3 SSD
+
+D3 SSD (tsys5, post-Friday SAS relocation) is 445 GB and 99% empty. Use it
+for a **Harbor** instance:
+
+| Property | Value |
+|----------|-------|
+| **Storage** | D3 SSD on tsys5 (NFS export, fast tier) |
+| **VM** | New VM `pfv-registry` on tsys5, local-nonprod boot, D3 data |
+| **Function** | (a) Pull-through cache for Docker Hub / Quay / gcr.io<br/>(b) Host private images<br/>(c) Cosign image signing verification |
+| **Exposure** | LAN-only. `192.168.3.50:443`. Not exposed to internet. |
+
+### 8.2 Pull-through cache benefit
+
+Cluster nodes have zero internet egress (per §3.3). Without a local cache,
+image pulls fail. With Harbor as a pull-through cache:
+
+```mermaid
+sequenceDiagram
+    WNODE->>HARBOR: docker pull nginx:1.25
+    alt cache hit
+        HARBOR-->>WNODE: layer bytes (LAN-speed)
+    else cache miss
+        HARBOR->>DOCKERHUB: pull nginx:1.25 (egress)
+        DOCKERHUB-->>HARBOR: layer bytes
+        HARBOR-->>WNODE: layer bytes (cached for next time)
+    end
+```
+
+Cluster nodes pull from Harbor over LAN (gigabit). Harbor is the only
+machine in the cluster with container-registry internet egress, and that
+egress can be locked to specific upstreams (docker.io, quay.io, gcr.io,
+ghcr.io).
+
+### 8.3 Supply-chain integrity (future)
+
+Harbor + Cosign lets you require that all images deployed to the ITAR
+tenant are signed by a trusted key. This is a strong ITAR/CISA-attestation
+control. Implementation deferred to a later session.

+```
+
+### 9.3 Add second and third cnodes
+
+```mermaid
+sequenceDiagram
+    autonumber
+    participant OP as Operator
+    participant PX as Proxmox host
+    participant C2 as cnode2
+    participant C3 as cnode3

+    C3->>C1: Join etcd cluster
+    Note over C1,C3: etcd now has 3/3 members → HA quorum
+```
+
+### 9.4 Post-bootstrap cluster configuration
+
+Once 3 cnodes are up and joined:
+
+1. **Install Cilium** (CNI) via Helm. Enable node-to-node encryption.
+2. **Install CSI drivers** — nfs-csi + local-path provisioner.
+3. **Create StorageClasses** — `local-fast`, `nfs-hdd`, `nfs-ssd`.
+4. **Deploy Harbor** on the `pfv-registry` VM, exposed at `192.168.3.50`.
+5. **Configure Kubernetes API OIDC** — Keycloak client (§5.3).
+6. **Apply default-deny NetworkPolicy** in all namespaces.
+7. **Install vcluster CLI** + create 4 tenant vclusters (§6).
+8. **First etcd snapshot** + automated daily snapshot cron → PBS.
+
+### 9.5 Add workers
+
+Workers are simpler (no etcd):
+
+```mermaid
+sequenceDiagram
+    OP->>PX: qm create + start wnode-X VM (Talos QCOW2)
+    WNODE->>WNODE: Boots maintenance mode
+    OP->>WNODE: talosctl apply --patch worker-X.yaml
+    WNODE->>C1: Kubelet registers with API server
+    C1-->>WNODE: Approved (auto via bootstrap token)
+    Note over WNODE: Joins cluster, becomes Ready
+```

+
+## 10. Disaster Recovery
+
+### 10.1 Backup strategy
+
+| Artifact | Frequency | Storage | Tool |
+|----------|-----------|---------|------|
+| **Talos secrets bundle** | Once (regen only on rotation) | 1Password + PBS (encrypted) | Manual |
+| **Machine configs** | Continuous (Git) | Git remote + PBS | Git |
+| **etcd snapshot** | Daily + before each change | PBS (tsys4 SMR target, 4.3 TB free) | `talosctl etcd snapshot` |
+| **vcluster etcd** | Daily per vcluster | PBS | `kubectl exec ... etcdctl snapshot` |
+| **Harbor metadata** | Daily | PBS | Harbor built-in backup |
+
+### 10.2 Restore scenarios
+
+**Lost 1 cnode (e.g., tsys9 disk failure):**
+
+1. Provision new VM on tsys9 (or other host with local SSD).
+2. Apply cnode2 machine config patch.
+3. New cnode joins etcd, syncs state from survivors.
+4. Quorum was never lost (2 of 3 alive throughout).
+
+**Lost 2 cnodes simultaneously (quorum lost):**
+
+1. Use surviving cnode's etcd snapshot.
+2. Provision 3 new cnode VMs.
+3. On first: `talosctl bootstrap --recover-from=snapshot.db`.
+4. Join other 2 cnodes.
+5. Workers reconnect automatically once API server is back.
+
+**Total cluster loss (all 3 cnodes):**
+
+1. Restore from latest PBS etcd snapshot.
+2. Provision new cnode VMs.
+3. `talosctl bootstrap --recover-from=snapshot.db`.
+4. Re-join workers.
+5. Verify tenant vclusters restored.
+
+### 10.3 Recovery time objectives
+
+| Scenario | RTO | RPO |
+|----------|-----|-----|
+| Single cnode failure | < 30 min | 0 (no data loss) |
+| Quorum loss (2 cnodes) | < 2 hours | ≤ 24 hours (last snapshot) |
+| Total cluster loss | < 4 hours | ≤ 24 hours |
+
+---
+
+## 11. Migration from Current State
+
+### 11.1 Current state
+
+- 5 cnode VMs exist (Debian stock + Tailscale).
+- **No k3s deployed yet.** Cluster was never bootstrapped.
+- 6 wnode VMs exist (some stopped).
+- No workloads running in k8s.
+
+### 11.2 Migration: clean cutover (not a migration)
+
+Since there is no etcd data and no workloads to preserve, the path is a
+**clean rebuild**:
+
+| Phase | Action | Risk |
+|-------|--------|------|
+| **0. Prep** | Generate Talos secrets. Store in 1Password + PBS. Write machine configs to Git. | Low. |
+| **1. Bootstrap 3 new cnodes** | Build 3 NEW Talos cnode VMs (not the existing 5). Use local-lvm boot disks (tsys9 × 2, tsys3 × 1 per §2.4 recommended spread). | Low. Existing Debian cnodes can keep running idle. |
+| **2. Configure cluster** | Install Cilium, CSI, StorageClasses, OIDC, Harbor. | Low. |
+| **3. Add workers** | Re-image existing wnode VMs as Talos, or build new ones. | Low. No workloads to drain. |
+| **4. Decommission old Debian cnodes** | Once cluster is stable, shut down + delete the 5 old Debian cnode VMs. | Low. |
+| **5. Tenant vclusters** | Stand up per-tenant vclusters. | Medium (policy tuning). |
+
+### 11.3 Open dependency: Friday hardware work
+
+Phases 1-2 require:
+
+- **tsys3 local-lvm available.** Per
+  [`../proxmox/PROJECT.md`](../proxmox/PROJECT.md) §3.3, tsys3 has 349 GB
+  free NVMe local-lvm. Currently unused. **Ready.**
+- **tsys9 local-lvm available.** 136 GB PNY CS900 SSD. **Ready.**
+- **D3 SSD relocated to tsys5 SAS.** Currently USB on tsys4. Per
+  [`../proxmox/TODO.md`](../proxmox/TODO.md) §2, scheduled for Friday.
+  Harbor depends on D3 being available on tsys5.
+
+Bootstrap of the cnodes does NOT depend on Friday hardware work. Only the
+Harbor registry does.
+
+---
+
+## Appendix: Open questions for next session
+
+1. **Confirm 3 vs 5 cnodes** (§2.1). Recommendation: 3.
+2. **Confirm cnode host spread** (§2.4). Recommendation: 3-host spread
+   (tsys9, tsys1, tsys3).
+3. **Static IPs for cnodes** (§3.2). Recommendation: yes, `192.168.3.31-33`.
+4. **Rancher vs Sidero Omni** for cluster management UI. Both viable.
+   Defer until cluster is up.
+5. **Subnet router ACL approval** on Tailscale admin console (§3). Needs
+   approval of `192.168.3.0/24` route advertisement.
+6. **ITAR worker node subset** (§6.3). Which wnodes are tainted for ITAR?
+   Recommendation: tsys6 + tsys7 (heaviest hosts, NFS-only boot) as
+   general capacity; tsys3 + tsys5 (local fast storage) reserved for
+   non-ITAR HPC.

+# Distro Decision: Talos Linux vs k3s
+
+> **Recommendation: Talos Linux.**
+> The k3s-on-Debian plan was sound before the ITAR/classified requirement
+> entered scope. Once classified workloads are on the table, Talos's
+> immutable, API-only, measured-boot-capable posture is materially easier
+> to certify and defend.
+
+**Last updated:** 2026-07-28
+
+---
+
+## 1. Decision context
+
+| Factor | Constraint |
+|--------|-----------|
+| **Workload class** | R&D + RackRental (containerlab) + **ITAR / classified** suborbital workloads + commercial (Starting Line Productions) |
+| **Compliance drivers** | ITAR (USML categories), possible classified handling (NIST 800-171, CNSSI 1253) |
+| **Hardware** | 7 standalone Proxmox hosts (no `pvecm`), managed via PDM. Live migration NOT available — disk moves via Proxmox "Storage Migrate" UI. |
+| **Network** | Gigabit symmetric fiber to residence. LAN-only cluster traffic desirable. Tailscale already in use (overlay for admin access). |
+| **Current cnode state** | Stock Debian VMs joined to Tailscale. **No k8s distribution has been deployed yet.** Clean cutover possible. |
+| **Operations** | Solo founder. Must be reproducible from Git, low-touch, low-debug-overhead. |
+
+---
+
+## 2. Head-to-head comparison
+
+### 2.1 ITAR / classified posture
+
+| Property | Talos Linux | k3s on Debian |
+|----------|-------------|---------------|
+| **Node OS mutability** | Immutable rootfs (squashfs, read-only). Reboot returns to known-good state. | Mutable. `apt install`, file edits persist. |
+| **Shell / SSH access** | **None.** No SSH daemon, no shell, no `kubectl debug node` shell. | Full SSH + bash. STIG hardening reduces (does not eliminate) attack surface. |
+| **Operational surface** | Single gRPC API (mTLS, signed certs, audit log) on port 50000. | SSH + kubelet API + etcd API + package manager + cron + systemd + userland. |
+| **Measured boot** | Supported. TPM attestation can prove the node booted the signed Talos image you pinned. | Possible but bolt-on; auditors will ask why you didn't disable the bootloader first. |
+| **Configuration provenance** | Entire node state is a YAML machine config in Git. `talosctl apply` is the only mutation path. | Config drift via SSH edits, package updates, manual service restarts. STIG/CAT-IV findings multiply. |
+| **Supply chain** | Every Talos release is a signed artifact (cosign). Pin by image digest. | Debian package provenance is good but the surface is enormous (~30K packages in a base install). |
+| **Forensic readiness** | API log + kernel log + Talos event log = sufficient for "what ran, when, with what config." | Same possible but requires explicit configuration to be trustworthy. |
+| **STIG / CIS conformance** | Intrinsically close. Talos publishes CIS benchmark results per release. | Requires running SCAP-STIG (already in this repo) and remediating findings continuously. |
+
+**Bottom line:** For classified workloads, an auditor's first question is
+"how do you prevent unauthorized changes to a node?" Talos's answer is
+"the OS is immutable and the only path is a signed API call." k3s's answer
+is"SSH is locked down and we scan with STIG." The first is structurally
+stronger; the second is operationally maintained.
+
+### 2.2 Operational considerations
+
+| Property | Talos | k3s |
+|----------|-------|-----|
+| **Familiarity** | New model (`talosctl apply`, no SSH). Learning curve. | Stock Debian + k3s binary. Familiar. |
+| **Debugging** | `talosctl logs`, `talosctl dmesg`, `talosctl dashboard`. No shell. | `ssh`, `journalctl`, `crictl`. Full shell. |
+| **Tailscale integration** | System extension (`siderolabs/tailscale`). Stable since Talos 1.3. | Native — `apt install tailscale`. Zero friction. |
+| **Backup / DR** | `talosctl etcd snapshot` (one command). Cluster can be restored from snapshot + machine configs. | DIY (`etcdctl snapshot` + manual cert management). |
+| **Upgrades** | `talosctl upgrade` — atomic, automated rollback on health-check failure. | Manual: drain, `k3s` package update, reboot, uncordon. |
+| **Proxmox compatibility** | QCOW2 image boots natively on KVM/QEMU. virtio-net, virtio-scsi, virtio-rng all supported. | Same. |
+| **Ecosystem maturity** | Production-grade. Sidero (the company) offers Omni (managed control plane for Talos). | Production-grade. Rancher (SUSE) backs it. |
+
+### 2.3 Cost of choosing Talos over the existing k3s plan
+
+The cnodes are currently **stock Debian VMs joined to Tailscale**. Critically,
+**no k3s cluster has been deployed yet** — k3s was only the *plan*. Therefore:
+
+- **No etcd data to migrate.** Clean cutover, not a migration.
+- **No workloads to drain.** The cluster is empty.
+- **Cnode VMs get re-imaged** with Talos QCOW2 (or rebuilt from scratch —
+  either way it's a `qm` script, not a stateful migration).
+- **Tailscale config shifts** from "installed via apt" to "Talos system
+  extension." (Or, per our recommendation in
+  [`ARCHITECTURE.md`](ARCHITECTURE.md) §3, **Tailscale moves off the cluster
+  nodes entirely** and onto the existing `tailscale-router` bastion as a
+  subnet router. Cluster nodes become LAN-only.)
+
+**Net cost:** rebuilding 3 cnode VMs as Talos + writing ~200 lines of
+machine config YAML. The hardening investment already encoded in
+`provisioning/Modules/Security/` is **not wasted** — it still applies to
+every non-cluster VM (netinfra, UCS, LibreNMS, SIEM, bastion, etc.). Only
+the cnodes/wnodes move to Talos.
+
+---
+
+## 3. Tailscale compatibility (deep-dive)
+
+Tailscale on Talos is well-supported but introduces a configuration dimension
+worth being explicit about. Three patterns exist:
+
+### Pattern A — Tailscale on every cluster node (what you have now, on Debian)
+
+Each cnode/wnode runs `tailscaled` and joins the tailnet. Cluster nodes have
+internet egress (to Tailscale DERP servers and for coordinate).
+
+- **Talos implementation:** add `siderolabs/tailscale` system extension to
+  each machine config, configure `machine.network.interfaces`.
+- **Pros:** Operator can hit any node's Talos API from any Tailscale device.
+- **Cons:** Cluster nodes have internet egress. For ITAR workloads, this is a
+  finding (data exfiltration path).
+
+### Pattern B — Tailscale on bastion only, SSH/API jump
+
+Cluster nodes are LAN-only. Operator Tunnels to bastion (existing
+`tailscale-router` VM), then runs `talosctl` from the bastion.
+
+- **Pros:** Zero internet egress from cluster nodes.
+- **Cons:** Two-step access. Bastion must run recent `talosctl`. Each operator
+  action originates from the bastion (auditable but clunky).
+
+### Pattern C — Tailscale subnet router on bastion (recommended)
+
+The existing `tailscale-router` VM advertises the cluster LAN subnet
+(e.g. `192.168.3.0/24`) into the tailnet as a **subnet route**. Operator's
+Tailscale client transparently routes cluster-bound traffic through the
+bastion. From the operator's workstation, `talosctl --nodes 192.168.3.x`
+"just works."
+
+- **Pros:**
+  - Cluster nodes have **zero internet egress** (strongest ITAR posture).
+  - Operator UX is unchanged from direct LAN access.
+  - All access is mediated by Tailscale's identity + ACLs (already integrated
+    with your env).
+  - Audit trail lives in Tailscale + bastion logs.
+- **Cons:**
+  - Bastion becomes a dependency for remote admin (LAN-local admin still
+    works without it).
+  - Must enable IP forwarding + subnet route approval in Tailscale ACLs.
+
+**Recommendation: Pattern C.** Documented in
+[`ARCHITECTURE.md`](ARCHITECTURE.md) §3.
+
+---
+
+## 4. Recommendation
+
+**Deploy Talos Linux** as the k8s distribution for `pfv-k8s`.
+
+### Justification
+
+1. **Compliance posture is structural, not operational.** "Immutable,
+   API-only, measured-boot" is a property of Talos itself; "STIG-hardened"
+   is a property of how Debian is operated. The first is dramatically
+   easier to argue to an ITAR counsel or classified accreditation officer
+   (DSS, DCSA) than the second.
+2. **Zero migration cost.** The k3s cluster was never deployed. Reimaging
+   3 cnodes with Talos is a `qm` script invocation, not a stateful
+   migration. The sunk cost of "we planned k3s" is **zero deployed state**.
+3. **Operational headroom.** Talos's `etcd snapshot` + `upgrade --stage` +
+   `apply-mode auto` reduce solo-founder ops burden. k3s is simpler to
+   learn but more error-prone to operate at HA.
+
+### Acknowledged tradeoffs
+
+- **Learning curve.** The Talos mental model (`machine config` + `talosctl`)
+  replaces SSH + systemd. Expect a one-week ramp for comfortable daily ops.
+- **No shell debugging.** When something breaks on a node, you cannot `ssh`
+  in. Mitigation: `talosctl logs/support` produces a support bundle
+  equivalent to a sosreport.
+- **Hardware/module surprises.** Talos ships a curated kernel. Anything
+  beyond virtio + common NIC drivers needs a system extension. On Proxmox
+  VMs this is **not expected to be a problem** — virtio is the path.
+- **Tailscale via system extension.** Adds one config dimension per node.
+  Mitigated by Pattern C (above), which removes Tailscale from cluster
+  nodes entirely.
+
+### What we keep from the k3s mental model
+
+- **Single binary on each node** semantics (Talos is conceptually similar).
+- **`kubectl` workflow unchanged.** Talos exposes a standard Kubernetes
+  API. `kubectl`, `helm`, `kustomize` all work as-is.
+- **Storage CSI choices** (`local-fast`, `nfs-hdd`, `nfs-ssd`) are
+  distro-independent.

+
+> **Status:** Draft for review. Companion to [`../proxmox/K8S.md`](../proxmox/K8S.md)
+> (which captured the storage/host analysis from the Proxmox audit).
+> This directory takes the next step: **which distro, how to build it,
+> how to operate it.**
+
+**Last updated:** 2026-07-28
+
+## Documents in this directory
+
+| Document | Purpose |
+|----------|---------|
+| [`DISTRO-DECISION.md`](DISTRO-DECISION.md) | Talos vs k3s analysis. Recommendation: **Talos**, with rationale grounded in the ITAR/classified requirement. |
+| [`ARCHITECTURE.md`](ARCHITECTURE.md) | Target architecture: control plane, network, identity, storage, tenant isolation. Mermaid diagrams included. |
+
+## TL;DR
+
+| Decision | Recommendation | Why |
+|----------|----------------|-----|
+| **Distro** | **k3s** (deployed) / **Talos** (for future ITAR) | k3s chosen for the regular R&D cluster now live on cnode1/2/3. Talos is the recommendation for when the ITAR/classified cluster comes online. |
+| **Runtime** | **containerd** | Talos/k3s default. |
+| **Cnode count** | **3** (deployed) | Standard HA. Tolerates 1 failure. |
+| **Admin access** | **Tailscale (all nodes joined)** | Currently all cnodes are on Tailscale directly. For ITAR cluster, move to subnet-router pattern. |
+| **Cluster network** | **Tailscale-only IPs** | All node-ip, advertise-address, TLS-SANs are 100.x Tailscale IPs. Zero LAN IPs in cluster state. |
+| **Identity** | **OIDC to Keycloak** on Cloudron (production) | Future work. |
+| **Multi-tenancy** | **vcluster** (per tenant) | Future work. |
+| **Local registry** | **Harbor on D3 SSD** (tsys5, 445 GB free) | Future work. |
+| **Storage classes** | `local-fast`, `nfs-hdd`, `nfs-ssd` | Per [`../proxmox/K8S.md`](../proxmox/K8S.md) §6. Future work. |
+
+## What this directory does NOT cover (deferred)
+
+- ETL tooling choice (GDAL/PostGIS/xarray/Dask) — affects RWX vs RWO design.
+- HPC job scheduler (Jobs / Argo Workflows / Volcano) — affects taint/label strategy.
+- vcluster per-tenant policy templates.
+- Solar-aware scale-out (PowerEdge 19xx/2950 hosts) — capacity planning only.
+
+These are tracked as future session work in [`../../STATUS.md`](../../STATUS.md).
+
+## Open question for the user
+
+1. **Cnode count: confirm 3 vs 5.** Recommendation is 3 (rationale in
+   [`ARCHITECTURE.md`](ARCHITECTURE.md) §2). If your ITAR counsel requires
+   2-failure tolerance on the control plane, keep 5.

+| cnode1 | **906** | tsys9 | D5 | **tsys4** | **HIGH** |
+| cnode2 | **705** | tsys7 | D2 | **tsys4** | **HIGH** |
+| cnode3 | 106 | tsys1 | S3 | tsys5 | OK |
+
+**CRITICAL: 2 of 3 active cnodes on tsys4.** tsys4 failure = cnode1 + cnode2 die = 1 of 3 = **QUORUM LOST**.
+
+**Fix needed:** Move cnode1 or cnode2 to tsys5 storage (S2 or S3). One migration via PDM "Storage Migrate" solves this.
+

+
+**Storage: 4 wnodes on tsys4, 2 on tsys5.** One wnode per host achieved.

+
+## 4. Critical HA Pairs — Storage Redundancy
+
+### 4.1 netinfra pair — FAILED (both on tsys4)
+
+| Role | VMID | Host | Disk | NFS Server |
+|------|------|------|------|-----------|
+| netinfra-01 | 103 | tsys1 | D5 | **tsys4** |
+| netinfra-02 | 904 | tsys9 | D2 | **tsys4** |
+
+**tsys4 failure = DNS/DHCP/NTP goes fully dark.**
+
+**Fix:** Migrate netinfra-02 (VMID 904) from D2 (tsys4) to S3 (tsys5) via PDM.
+
+### 4.2 UCS pair — FAILED (both on tsys4)
+
+| Role | VMID | Host | Disk | NFS Server |
+|------|------|------|------|-----------|
+| ucs-01 | 108 | tsys1 | D2 | **tsys4** |
+| ucs-02 | 902 | tsys9 | D5 | **tsys4** |
+
+**tsys4 failure = LDAP/AD goes fully dark.**
+
+**Fix:** Migrate ucs-02 (VMID 902) from D5 (tsys4) to S2 (tsys5) via PDM.
+
+### 4.3 Corrected placement (after migration)
+
+| VM | Host | Disk | NFS Server | Failure survival |

+## 5. Storage Concentration
+
+| Storage target | # running VMs | % of fleet |
+|---------------|--------------|------------|

+| local-lvm (various hosts) | 2 | 5% |
+
+**26 of 44 running VMs (59%) store their disks on tsys4 NFS exports.**
+(Was 68% in the previous audit — improving but still concentrated.)
+
+---
+
+## 6. Pre-k8s Buildout Action Items
+
+These must be done before or during k8s worker node bringup:
+
+### 6.1 CRITICAL: Migrate HA pairs to separate storage (PDM, 10 min)
+
+1. `netinfra-02` (VMID 904): D2 → S3 (tsys4 → tsys5)
+2. `ucs-02` (VMID 902): D5 → S2 (tsys4 → tsys5)
+
+These are PDM "Storage Migrate" operations — no VM rebuild needed.
+
+### 6.2 CRITICAL: Fix active cnode quorum (PDM, 5 min)
+
+Move one active cnode from tsys4 to tsys5 storage:
+- Best candidate: cnode1 (VMID 906) D5 → S2 (tsys4 → tsys5)
+- Result: cnode1 on tsys5, cnode2 on tsys4, cnode3 on tsys5
+- tsys4 failure = cnode2 dies only = 2 of 3 = **quorum OK**
+
+### 6.3 Join workers to k3s cluster
+
+Current wnodes exist as VMs but are not joined to the k3s cluster. Need to:
+1. Install k3s agent on each wnode (using join token from cnode1)
+2. Configure `--node-ip=<tailscale-ip>` on each
+3. Label/taint per workload role
+
+### 6.4 Friday hardware work (still pending)
+
+- tsys4: PCIe NIC + 64 GB RAM (currently 15 GB)
+- tsys5: 2nd ethernet cable + NVMe + D3 SSD relocation
+- tsys2: Rebuild from Win10 to Proxmox

+## 1. Workload Profile
+
+This cluster runs **R&D and RackRental (containerlab) workloads** via
+Kubernetes. Production (Gitea, RustFS, Redmine, websites) lives on a VPS in
+Reston, VA running Cloudron.
+
+**Workload types expected:**
+
+| Type | Description | Storage need | RAM need | Examples |
+|------|------------|-------------|----------|---------|
+| **ETL (weather/GIS)** | Batch processing of large geospatial datasets. Sequential reads, transform, sequential writes. | High capacity (100s of GB), moderate IOPS | Medium (8-32 GB per job) | GRIB/NetCDF processing, raster reprojection |
+| **HPC (hardware startup)** | Compute-intensive simulations, firmware build pipelines, hardware-in-the-loop testing. | Low capacity, moderate IOPS | High (32-128 GB per job) | RTL simulation, PCB thermal analysis |
+| **RackRental (containerlab)** | Rapid deployment/teardown of network lab topologies. Many containers, short-lived. | Low capacity, high IOPS (container image pulls) | Low-Medium (4-16 GB) | Network topology testing, protocol validation |
+
+**Key storage insight:** ETL workloads need bulk capacity (NFS-HDD is fine --
+sequential I/O). HPC and containerlab need low-latency random I/O (local
+SSD/NVMe is essential). The tiered StorageClass design (section 6) serves both.
+
+---
+
+## 2. Current State
+
+### 2.1 pfv-k8s nodes and their storage
+
+| Node | Type | Host | Storage | Disk type | Status |
+|------|------|------|---------|-----------|--------|
+| cnode1 (107) | control | tsys1 | D5 (tsys4) | NFS-HDD | running |
+| cnode2 (603) | control | tsys6 | D2 (tsys4) | NFS-HDD | running |
+| cnode3 (106) | control | tsys1 | D2 (tsys4) | NFS-HDD | running |
+| cnode4 (601) | control | tsys6 | D2 (tsys4) | NFS-HDD | running |
+| cnode5 (602) | control | tsys6 | D5 (tsys4) | NFS-HDD | running |
+| wnode-tsys3 (313) | worker | tsys3 | D5 (tsys4) | NFS-HDD | running |
+| wnode-tsys5 (509) | worker | tsys5 | D2 (tsys4) | NFS-HDD | running |
+| wnode-tsys6 (100) | worker | tsys6 | D5 (tsys4) | NFS-HDD | **STOPPED** |
+| wnode-tsys7 (701) | worker | tsys7 | D5 (tsys4) | NFS-HDD | running |
+| wnode-tsys9 (905) | worker | tsys9 | S3 (tsys5) | NFS-HDD | running |
+
+### 2.2 Problems
+
+1. **100% of cnodes on tsys4 NFS.** D2 disk failure loses 3 of 5 cnodes =
+   etcd quorum lost.
+2. **90% of all k8s nodes on tsys4 NFS.** tsys4 failure kills the cluster.
+3. **Zero nodes use SSD or NVMe.** All on NFS-over-HDD.
+4. **Zero nodes use local-lvm.** tsys3/6/7/9 all have empty local storage
+   (349 GB / 1.7 TB / 1.7 TB / 136 GB SSD respectively).
+5. **wnode-tsys6 is stopped.** Reduces cluster capacity.
+6. **3 cnodes on tsys6** -- should be on lighter hosts to free tsys6 for workers.
+
+---
+
+## 3. Target Architecture
+
+### 3.1 Design principles
+
+1. **Cnodes on lightweight hosts** (tsys1, tsys9, tsys3) -- frees tsys6/7 for
+   heavy workers.
+2. **Cnode storage split across tsys4 and tsys5** -- etcd survives either
+   storage server failing.
+3. **Wnode boot disks on local storage** -- eliminates NFS latency for
+   container runtime and kubelet.
+4. **Wnode data disks on NFS-HDD** -- bulk capacity for ETL/weather/GIS.
+5. **tsys5 NVMe dedicated to wnode-tsys5** -- fastest tier for HPC jobs.
+6. **One wnode per hypervisor host** -- maximize total cluster capacity.
+
+### 3.2 Target node-host-storage matrix
+
+| Node | Type | Host | Boot disk | Data disk | Disk type |
+|------|------|------|-----------|-----------|-----------|
+| cnode1 | control | tsys1 | D5 (tsys4) | -- | NFS-HDD |
+| cnode2 | control | tsys9 | D2 (tsys4) | -- | NFS-HDD |
+| cnode3 | control | tsys1 | S2 (tsys5) | -- | NFS-HDD |
+| cnode4 | control | tsys9 | D5 (tsys4) | -- | NFS-HDD |
+| cnode5 | control | tsys3 | S3 (tsys5) | -- | NFS-HDD |
+| wnode-tsys1 | worker | tsys1 | D5 (tsys4) | -- | NFS-HDD (small) |
+| wnode-tsys2 | worker | tsys2 | **NVMe (960 PRO 512GB)** | **SATA SSD (850 EVO 1TB)** | **NVMe + SSD -- no NFS needed** |
+| wnode-tsys3 | worker | tsys3 | **local-lvm (NVMe PM961)** | S3 (NFS) | **LOCAL-NVMe** |
+| wnode-tsys5 | worker | tsys5 | **NVMe (local, Friday)** | local-nonprod (HDD) | **NVMe** |
+| wnode-tsys6 | worker | tsys6 | D2 (tsys4 NFS) | -- | NFS-HDD (local-lvm is USB 2.0 -- do not use) |
+| wnode-tsys7 | worker | tsys7 | D5 (tsys4 NFS) | -- | NFS-HDD (local-lvm is USB 2.0 -- do not use) |
+| wnode-tsys9 | worker | tsys9 | **local-lvm (SSD)** | S2 (NFS) | **LOCAL-SSD** |
+
+### 3.3 Storage server distribution after changes
+
+| Storage server | cnodes | wnodes (boot) | wnodes (data) |
+|---------------|--------|---------------|---------------|
+| tsys4 (D2) | cnode2 | wnode-tsys6 | wnode-tsys7 |
+| tsys4 (D5) | cnode1, cnode4 | wnode-tsys1 | -- |
+| tsys5 (S2) | cnode3 | wnode-tsys9 | -- |
+| tsys5 (S3) | cnode5 | -- | wnode-tsys3 |
+
+**Note:** wnode-tsys2 needs no NFS (1.5 TB local SSD). wnode-tsys6/7 stay on
+NFS by design -- their local-lvm is USB 2.0 portable HDD (~30 MB/s), slower
+than NFS-HDD, and the user has chosen not to install internal drives.
+
+**No single disk or server is a quorum-losing failure point.**
+
+---
+
+## 4. Control Plane (Cnodes)
+
+### 4.1 Cnode sizing
+
+Each cnode: 4 cores, 4 GB RAM, 32 GB disk. This is sufficient for etcd +
+kubernetes control plane components (API server, scheduler, controller-manager).
+
+### 4.2 Cnode host placement rationale
+
+| Host | cnodes | RAM for cnodes | Total host RAM | Remaining for other VMs |
+|------|--------|---------------|---------------|------------------------|
+| tsys1 | 2 (cnode1, cnode3) | 8 GB | 32 GB | ~24 GB (but 11 infra VMs consume most) |
+| tsys9 | 2 (cnode2, cnode4) | 8 GB | 24 GB | ~16 GB (4 infra VMs + 1 wnode) |
+| tsys3 | 1 (cnode5) | 4 GB | 32 GB | ~28 GB (1 wnode at 20 GB = 8 GB headroom) |
+
+**tsys6 and tsys7 have ZERO cnodes** -- fully dedicated to heavy worker nodes.
+
+### 4.3 Cnode storage placement rationale
+
+The 5 cnodes are split 3-on-tsys4 / 2-on-tsys5:
+
+| Disk | cnodes | Rationale |
+|------|--------|-----------|
+| D5 (tsys4 HDD) | cnode1, cnode4 | Spread load across 2 disks on tsys4 |
+| D2 (tsys4 HDD) | cnode2 | Only 1 cnode on D2 (was 3 -- reduces blast radius) |
+| S2 (tsys5 HDD) | cnode3 | tsys5 storage for quorum diversity |
+| S3 (tsys5 HDD) | cnode5 | tsys5 storage, different disk than S2 |
+
+**If D2 fails:** cnode2 dies. 4 of 5 survive. Quorum OK.
+**If D5 fails:** cnode1 + cnode4 die. 3 of 5 survive. Quorum OK.
+**If tsys4 fails:** cnode1, cnode2, cnode4 die. cnode3 + cnode5 survive on
+tsys5. **Only 2 of 5 -- QUORUM LOST.**
+
+Wait -- that is a problem. If tsys4 goes completely offline, we lose 3
+cnodes and only have 2 on tsys5. That loses quorum (need 3).
+
+**Revision needed:** Move 1 more cnode to tsys5 storage. Target: 2 on tsys4,
+3 on tsys5. But that means tsys5 failure (3 cnodes die) leaves only 2 on
+tsys4. Same problem inverted.
+
+The fundamental issue: with 5 cnodes and 2 storage servers, the best split is
+3/2. The server holding 3 cnodes is a quorum-loss risk if it fails. The server
+holding 2 cnodes is safe (3 survive).
+
+**Proper solution: 3 cnodes on the "less likely to fail" server, 2 on the
+other.** After Friday's hardware work:
+- tsys4 will have a new PCIe NIC + 64 GB RAM -- more reliable
+- tsys5 will have bond0 fixed + NVMe -- more reliable
+
+Either way, 3/2 split means one server failure could lose quorum. **To truly
+solve this, use a 3rd storage target.** Options:
+- Use tsys9 local SSD for 1 cnode (breaks the 2-server model, adds a 3rd
+  independent failure domain)
+- Use local-lvm on the cnode's own host (etcd data is local to the VM's host,
+  no NFS dependency at all)
+
+**Best option: put cnode boot disks on local-lvm where available.** This
+eliminates NFS entirely for the control plane. Each cnode's etcd data lives on
+its own host's local disk -- no shared dependency.
+
+| cnode | Host | **Recommended storage** | Type |
+|-------|------|------------------------|------|
+| cnode1 | tsys1 | **local-lvm** (if space) or D5 (tsys4) | LOCAL-HDD or NFS-HDD |
+| cnode2 | tsys9 | **local-lvm (SSD)** | **LOCAL-SSD** |
+| cnode3 | tsys1 | **S2 (tsys5)** | NFS-HDD |
+| cnode4 | tsys9 | **local-lvm (SSD)** | **LOCAL-SSD** |
+| cnode5 | tsys3 | **local-lvm** | LOCAL-HDD |
+
+With this layout, a tsys4 failure takes down 0 cnodes. A tsys5 failure takes
+down 1 (cnode3). A host failure takes down at most 2 cnodes. Quorum always
+survives.
+
+**This is the recommended approach.** Local storage for cnodes wherever
+possible. NFS only as fallback.
+
+### 4.4 etcd performance on local vs NFS
+
+| Storage | Typical fsync latency | etcd commit latency | Impact |
+|---------|----------------------|--------------------|--------|
+| NFS-HDD (via USB dongle on tsys4) | 5-15 ms | 10-30 ms | Slow API responses, sluggish pod scheduling |
+| NFS-HDD (via PCIe NIC, post-Friday) | 2-8 ms | 5-15 ms | Better but still network-bound |
+| Local HDD (tsys1/3/6/7 local-lvm) | 1-5 ms | 3-10 ms | No network hop, moderate improvement |
+| Local SSD (tsys9 PNY CS900) | 0.1-0.5 ms | 0.5-2 ms | **10-30x faster than NFS-HDD** |
+| NVMe (tsys5, Friday) | 0.02-0.1 ms | 0.1-0.5 ms | **100x faster than NFS-HDD** |
+
+etcd is the heartbeat of the kubernetes control plane. Every API call, every
+pod schedule, every controller reconciliation involves an etcd write. Cutting
+etcd commit latency from 15 ms to 1 ms makes the entire cluster feel 15x more
+responsive. **This is the single highest-impact change for k8s performance.**
+
+---
+
+## 5. Worker Nodes (Wnodes)
+
+### 5.1 One wnode per hypervisor host
+
+| Host | wnode | Boot disk | Data disk | Total RAM | wnode RAM | Role |
+|------|-------|-----------|-----------|-----------|-----------|------|
+| tsys1 | wnode-tsys1 | D5 (tsys4 NFS) | -- | 32 GB | 4-8 GB | Small worker, infra co-tenant |
+| tsys2 | wnode-tsys2 | **NVMe (960 PRO 512GB)** | **SATA SSD (850 EVO 1TB)** | 32 GB | 16-24 GB | **Best storage of any worker -- 1.5TB local SSD, no NFS needed** |
+| tsys3 | wnode-tsys3 | **local-lvm (349 GB)** | S3 (NFS) | 32 GB | 20 GB | General worker |
+| tsys5 | wnode-tsys5 | **NVMe (local)** | local-nonprod (HDD) | 96 GB | 32-64 GB | **HPC/ETL powerhouse** |
+| tsys6 | wnode-tsys6 | D2 (tsys4 NFS) | -- | 128 GB | 64-96 GB | **Heavy worker, max RAM.** local-lvm is USB 2.0 -- stays on NFS |
+| tsys7 | wnode-tsys7 | D5 (tsys4 NFS) | -- | 192 GB | 96-128 GB | **Heavy worker, max RAM.** local-lvm is USB 2.0 -- stays on NFS |
+| tsys9 | wnode-tsys9 | **local-lvm SSD (136 GB)** | S2 (NFS) | 24 GB | 4-8 GB | Small worker, SSD boot |
+
+### 5.2 Why boot disks on local-lvm
+
+Current: all wnodes boot from NFS. Every container image pull, every kubelet
+log write, every ephemeral volume traverses the NFS network path.
+
+With local-lvm boot disks:
+- **Container image pulls** write to local disk (100-150 MB/s HDD, no network
+  hop) instead of NFS-HDD (80-120 MB/s with network latency)
+- **kubelet logs** stay local (no NFS writes for log rotation)
+- **ephemeral storage** (emptyDir volumes) uses local disk by default
+- **NFS server failure does not kill the wnode** -- the VM stays running, only
+  the data disk (if mounted) goes away
+
+### 5.3 Wnode sizing guidance
+
+| Host | Recommended wnode config | Rationale |
+|------|------------------------|-----------|
+| tsys7 (192 GB) | 8-12 cores, 96-128 GB RAM, NFS boot | Largest host -- run the heaviest ETL/HPC jobs here. local-lvm is USB 2.0 |
+| tsys6 (128 GB) | 8 cores, 64-96 GB RAM, NFS boot | Second-largest -- parallel heavy jobs. local-lvm is USB 2.0 |
+| tsys5 (96 GB + NVMe) | 4 cores, 32-64 GB RAM, NVMe boot + HDD data | NVMe makes this fastest for I/O-bound HPC |
+| tsys3 (32 GB) | 4 cores, 20 GB RAM, local-lvm boot | General-purpose worker |
+| tsys2 (32 GB, NVMe+SSD, incoming) | 4 cores, 16-24 GB RAM, **NVMe boot + SSD data** | **Fastest storage worker** -- HPC with I/O bounds |
+| tsys1 (32 GB) | 2 cores, 4-8 GB RAM | Small worker, don't starve infra VMs |
+| tsys9 (24 GB) | 2-4 cores, 4-8 GB RAM | Small worker, SSD boot is the advantage |
+
+### 5.4 Tainting and labeling strategy
+
+Label wnodes by capability so the k8s scheduler can target them:
+
+```yaml
+# Heavy RAM hosts (ETL/HPC)
+wnode-tsys6: workload=heavy, ram=128g
+wnode-tsys7: workload=heavy, ram=192g
+
+# NVMe host (I/O-intensive HPC)
+wnode-tsys5: workload=hpc, storage=nvme
+
+# SSD boot host (low-latency)
+wnode-tsys9: workload=light, storage=ssd
+
+# General workers
+wnode-tsys3: workload=general
+wnode-tsys2: workload=storage-fast, storage=nvme
+wnode-tsys1: workload=light
+```
+
+Then use nodeSelector or nodeAffinity in job specs:
+
+```yaml
+# Weather/GIS ETL job -- needs lots of RAM
+spec:
+  nodeSelector:
+    workload: heavy
+
+# Firmware build -- needs fast storage
+spec:
+  nodeSelector:
+    storage: nvme
+```
+
+---
+
+## 6. Storage Class Design
+
+### 6.1 Proposed StorageClasses
+
+| StorageClass | Provisioner | Where | Speed | Use case |
+|-------------|------------|-------|-------|----------|
+| `local-fast` | local-path (k8s) | wnode local-lvm / NVMe | 100-3500 MB/s | Container runtime, scratch, databases |
+| `nfs-hdd` | nfs-subdir-external-provisioner | tsys4 D2/D5, tsys5 S1-S4 | 80-120 MB/s | Bulk data, weather/GIS datasets |
+| `nfs-ssd` | nfs-subdir-external-provisioner | tsys4 D3, tsys5 T5-SSD | 200-400 MB/s | Latency-sensitive persistent data |
+
+### 6.2 How this maps to wnode disk topology
+
+Each wnode has:
+- **Disk 1 (boot/OS):** local-lvm or NVMe. Contains the OS, kubelet, container
+  runtime. k8s `local-fast` StorageClass provisioner points here.
+- **Disk 2 (bulk data, optional):** NFS mount. Mounted inside the VM as a
+  second block device or filesystem. k8s `nfs-hdd` provisioner points here.
+
+Inside k8s, pods request storage via PVC:
+
+```yaml
+# ETL job: needs bulk storage for weather data
+apiVersion: v1
+kind: PersistentVolumeClaim
+spec:
+  storageClassName: nfs-hdd
+  accessModes: [ReadWriteMany]  # NFS allows RWX
+  resources:
+    requests:
+      storage: 500Gi
+
+# HPC job: needs fast scratch
+spec:
+  storageClassName: local-fast
+  accessModes: [ReadWriteOnce]
+  resources:
+    requests:
+      storage: 50Gi
+```
+
+### 6.3 NFS-SSD tier (D3 and T5-SSD -- both on tsys5 after Friday)
+
+**Storage philosophy (user directive): NVMe/SSD is EXCLUSIVELY for k8s worker
+scratch space, with the exception of ultix-streaming which stays on T5-SSD.
+Spinning rust hosts all other infrastructure VMs** (UCS, netinfra, LibreNMS,
+SIEM, etc.).
+
+The SSD NFS exports:
+- **D3 (tsys5 SAS, 445 GB free):** k8s scratch exclusively (etcd, container
+  cache, ephemeral volumes). Currently 99% empty.
+- **T5-SSD (tsys5 SAS, 140 GB free after ultix-streaming):** ultix-streaming
+  occupies 83 GB. Remaining 140 GB available for k8s use.
+
+**tsys5 is the fast-tier hub:** NVMe (local) + D3 SSD + T5-SSD all on one host.
+This simplifies the StorageClass design -- latency-sensitive k8s PVCs target
+tsys5 SSD exports, bulk PVCs target either server.
+
+### 6.4 NFS data distribution across storage servers
+
+To avoid re-creating the "everything on tsys4" problem, distribute NFS data
+disks across both servers:
+
+| wnode | Boot (local) | Bulk data (NFS) | NFS server |
+|-------|-------------|-----------------|------------|
+| wnode-tsys3 | local-lvm | S3 | tsys5 |
+| wnode-tsys5 | NVMe | local-nonprod | local (no NFS) |
+| wnode-tsys6 | D2 (tsys4 NFS) | -- | tsys4 |
+| wnode-tsys7 | D5 (tsys4 NFS) | -- | tsys4 |
+| wnode-tsys9 | local-lvm (SSD) | S2 | tsys5 |
+
+This balances: 2 wnodes using tsys4 for bulk data, 2 using tsys5.
+
+---
+
+## 7. ETL/HPC Considerations
+
+### 7.1 Weather/GIS ETL pipeline
+
+Typical flow: download GRIB/NetCDF files -> process (reproject, aggregate) ->
+store results.
+
+| Stage | Storage class | Why |
+|-------|-------------|-----|
+| Download raw data | `nfs-hdd` | Large sequential writes. NFS-HDD handles this well. |
+| Processing scratch | `local-fast` | Random access during transform. Local disk avoids NFS latency. |
+| Store results | `nfs-hdd` | Large sequential writes. Persistent. |
+
+**Recommendation:** Deploy a `local-fast` PV mount as `/scratch` on every
+wnode. ETL jobs use `/scratch` for intermediate processing and write final
+output to the NFS-mounted `/data`.
+
+### 7.2 HPC workloads (hardware startup)
+
+Use cases: RTL simulation, PCB thermal analysis, firmware build pipelines.
+
+| Workload | Best wnode | Why |
+|----------|-----------|-----|
+| RTL simulation (CPU-bound, high RAM) | tsys7 (192 GB) | Most RAM, most cores (24t) |
+| Firmware builds (I/O-bound, moderate RAM) | tsys5 (NVMe) | Fastest storage for compile I/O |
+| Hardware-in-the-loop (latency-sensitive) | tsys9 (local SSD) | Lowest latency storage |
+| Parallel batch jobs | tsys6 + tsys7 | Distribute across both heavy hosts |
+
+### 7.3 RackRental/containerlab
+
+Rapid container deployment. Key need: fast container image pulls.
+
+This is where **local-lvm boot disks** shine. Currently, every container image
+pull writes through NFS to a spinning disk -- slow. With local-lvm, images
+cache on local disk (even HDD is 2-3x faster than NFS-HDD for random I/O).
+On tsys9 (SSD) and tsys5 (NVMe), image pulls are near-instant.
+
+### 7.4 Data locality for ETL
+
+For weather/GIS data that is read repeatedly (e.g., climate reanalysis), cache
+it on local-lvm of the heavy hosts:
+
+```
+tsys3 local-lvm (NVMe 349 GB): /data/cache/weather/  -- fastest cache tier
+tsys5 NVMe (local): /data/cache/gis/                 -- fastest cache tier
+```
+
+**Note:** tsys6/7 local-lvm is USB 2.0 portable HDD (~30 MB/s) -- cannot
+be used for caching. Pre-populate weather/GIS data on D2/D5 (NFS) instead.
+
+This avoids re-reading the same data from the same NFS export on every job
+if the data is already cached in the page cache.
+
+---
+
+## 8. Migration Plan
+
+**Key enabler:** The hosts are standalone Proxmox installs, but **Proxmox
+Datacenter Manager (PDM)** manages them collectively and supports VM migration
+between nodes. Storage migration can be done via the PDM/Proxmox UI rather
+than manual disk copies -- the destination node just needs access to the target
+storage (which all nodes have for NFS exports, and local storage can be
+migrated through the UI's "Storage Migrate" function).
+
+### 8.1 Phase 1: Friday (after hardware work)
+
+After tsys5 cable + NVMe and tsys4 NIC + RAM:
+
+1. **Format tsys5 NVMe** as local directory storage (e.g., `nvme-local`)
+2. **Restart wnode-tsys6** (VM 100). Keep on NFS (D5). local-lvm is USB 2.0 --
+   do not use for VM storage. Recreate on D2 or D5 NFS.
+3. **Move wnode-tsys9** (VM 905) disk from S3 (NFS) to local-lvm (SSD).
+
+### 8.2 Phase 2: Cnode rebalance (maintenance window)
+
+These changes require creating new VMs on target hosts and migrating disks.
+Plan for a maintenance window with the k8s cluster briefly down.
+
+1. Create cnode2 on tsys9 (local-lvm SSD if possible, or D2 NFS).
+2. Create cnode4 on tsys9 (D5 NFS or local-lvm SSD).
+3. Create cnode5 on tsys3 (S3 NFS or local-lvm).
+4. Move cnode3 disk from D2 to S2 (tsys4 to tsys5).
+5. Join new cnodes to etcd cluster, drain old cnode2/4/5, remove.
+
+### 8.3 Phase 3: Wnode local storage migration (maintenance window)
+
+1. Recreate wnode-tsys3 with boot disk on local-lvm (349 GB).
+2. wnode-tsys6 stays on NFS (local-lvm is USB 2.0 HDD -- not suitable).
+3. wnode-tsys7 stays on NFS (same reason).
+4. Recreate wnode-tsys5 with boot disk on NVMe.
+5. Add data disks (NFS) as second SCSI devices where applicable.
+
+### 8.4 Phase 4: tsys2 integration (when rebuilt)
+
+1. Install Proxmox on tsys2.
+2. Run `scripts/check.sh` to inventory.
+3. Run `scripts/apply-tunings.sh --apply`.
+4. Create wnode-tsys2 with **boot disk on NVMe (960 PRO)** and **data disk on SATA SSD (850 EVO)**. No NFS needed -- 1.5 TB local SSD is the most local storage of any worker.
+5. Join to k8s cluster.
+
+### 8.5 Phase 5: Critical VM relocation
+
+1. Move netinfra-02 (VM 904) from D2 to S3 (tsys5 HDD).
+2. Move ucs-02 (VM 902) from D5 to S2 (tsys5 HDD).
+3. (No change to T5-SSD -- ultix-streaming stays.)
+
+---
+
+## Open questions for next session
+
+1. **Are the hosts a Proxmox cluster (pvecm) or standalone?** This determines
+   whether live migration is available (huge simplification) or we need manual
+   disk migration. Check `pvecm status` on each host.
+2. **What k8s distribution is in use?** (k3s, kubeadm, RKE2?) This affects how
+   nodes are joined/drain and how StorageClasses are configured.
+3. **Container runtime?** (containerd, cri-o?) Affects local storage layout.
+4. **Is there a container image registry mirror in the cluster?** Or do all
+   pulls go to Docker Hub / external? A local registry on D3 SSD would speed
+   up all pulls.
+5. **What specific ETL tools?** (GDAL, PostGIS, xarray, Dask?) This affects
+   whether jobs need shared (RWX) or exclusive (RWO) storage.
+6. **HPC job scheduler?** (plain k8s Jobs, Argo Workflows, Volcano?) Affects
+   how we label and taint nodes.

+## 1. Executive Summary
+
+The cluster consists of 7 active Proxmox hosts and 1 incoming (pfv-tsys2),
+running 43 VMs across two NFS storage servers (tsys4, tsys5). Host-side
+performance tunings are complete on 5 of 7 hosts. Two hosts (tsys4, tsys5)
+are blocked on physical hardware work scheduled for Friday.
+
+**Progress since initial audit:** The user has been actively rebalancing k8s
+nodes via PDM. Storage distribution improved from 90%/10% (tsys4/tsys5) to
+73%/27%. One cnode now uses tsys5 storage (cnode5 on S2). More migration
+needed for etcd quorum survival.
+
+The VM-layer assessment reveals:
+
+| # | Finding | Severity | Status |
+|---|---------|----------|--------|
+| 1 | **4 of 5 cnodes still store disks on tsys4 NFS.** cnode5 moved to tsys5. Still need 1-2 more moves for quorum survival. | **CRITICAL** | Improving |
+| 2 | **Both -01/-02 infrastructure pairs (netinfra, UCS) on tsys4 NFS only.** | **HIGH** | TODO today |
+| 3 | **No k8s node uses SSD or NVMe yet.** tsys3 has 349 GB unused local NVMe; tsys9 has 136 GB local SSD. | **HIGH** | Deferred to k8s session |
+| 4 | **D3 SSD (tsys4, USB) is 99% empty (445 GB free).** Moving to tsys5 SAS Friday. | **MEDIUM** | Friday |

+## 2. Host Fleet
+
+### 2.1 Inventory
+
+| Host | Model | CPU (year) | Cores | RAM | Local Disk | Role (intended) | Tuning |
+|------|-------|-----------|-------|-----|-----------|-----------------|--------|
+| pfv-tsys1 | OptiPlex 9020 | i7-4770 Haswell (2013) | 4c/8t | 32 GB DDR3 | HDD (LVM-thin) | **Infrastructure** | Done |
+| pfv-tsys2 | Precision 5520 | i7-7820HQ Kaby Lake (2017) | 4c/8t | 32 GB (max) | **NVMe 512GB + SATA SSD 1TB** | **Kubernetes** | Incoming (Win10) |
+| pfv-tsys3 | Precision 7510 | Xeon E3-1535M v5 Skylake (2015) | 4c/8t | 32 GB DDR4 | HDD (LVM-thin) | **Kubernetes** | Done |
+| pfv-tsys4 | Precision T1700 | Xeon E3-1246 v3 Haswell (2013) | 4c/8t | 16 GB DDR3 | 6 disks (HDD+SSD+SMR) | **Storage (NFS+PBS)** | Blocked (NIC+RAM) |
+| pfv-tsys5 | Precision T7500 | Xeon E5620 Westmere (2010) | 4c/8t | 96 GB DDR3 | 6 disks (HDD+SSD) | **Storage (NFS+VMs)** | Blocked (cable) |
+| pfv-tsys6 | PowerEdge R610 | 2x Xeon E5530 Nehalem (2009) | 8c/16t | 128 GB DDR3 | HDD (LVM-thin) | **Kubernetes** | Done |
+| pfv-tsys7 | PowerEdge R620 | 2x Xeon E5-2630 v2 Ivy Bridge (2013) | 12c/24t | 192 GB DDR3 | HDD (LVM-thin) | **Kubernetes** | Done |
+| pfv-tsys9 | OptiPlex 7080 | i5-10500 Comet Lake (2020) | 6c/12t | 24 GB DDR4 | **250 GB SSD** (PNY CS900) | **Infrastructure** | Done |
+
+### 2.2 Role taxonomy (per user directive)
+
+| Role | Hosts | Workload |
+|------|-------|----------|
+| **Infrastructure + k8s control** | tsys1, tsys9 | Infra VMs (netinfra, UCS, PBS, CA, HA) + pfv-k8s cnodes (control plane) + small wnodes |
+| **Kubernetes workers** | tsys2, tsys3, tsys6, tsys7 | pfv-k8s wnodes (heavy workers) -- these hosts have the RAM (32-192 GB) for ETL/HPC |
+| **Storage** | tsys4, tsys5 | NFS server + PBS backup target. tsys5 also runs sectestbed/preprod VMs |
+
+**Design rationale:** cnodes (control plane) are lightweight (4 cores, 4 GB
+RAM each) and are weighted toward tsys1/tsys9 to keep the heavy RAM/CPU hosts
+(tsys6 with 128 GB, tsys7 with 192 GB) free for large worker nodes. wnodes
+run one per hypervisor host across the fleet to maximize total cluster capacity.
+
+pfv-k8s runs all R&D and RackRental (containerlab) workloads via Kubernetes.
+Production (Gitea, RustFS, Redmine, websites) lives on a VPS in Reston, VA
+running Cloudron -- not in this cluster.

+
+## 3. Storage Architecture
+
+### 3.1 NFS exports from tsys4 (primary storage server)
+
+| Export | Disk model | Type | Bus | Total | Used | Free | Use% |
+|--------|-----------|------|-----|-------|------|------|------|
+| D2 | WDC WD30EFRX Red | HDD (7200rpm) | SATA | 2.7 TB | 187 GB | **2.4 TB** | 8% |
+| ~~D3~~ | ~~SK hynix SC300~~ | ~~SSD~~ | ~~USB~~ | — | — | — | **moving to tsys5 Friday** |
+| D5 | Hitachi HDS72302 | HDD (7200rpm) | SATA | 1.8 TB | 236 GB | **1.5 TB** | 14% |
+
+Non-exported disks on tsys4:
+- sda (Hitachi 1.8T) at /mnt/albert -- not NFS shared, 1.7 TB free
+- sdd (WDC 1T) -- **idle, unmounted, removable** (free up for other use)
+- sdf (WDC 4.5T SMR) at /mnt/backup -- **PBS backup target**, 4.3 TB free
+
+**D3 migration (Friday):** The SK hynix SC300 SSD is currently USB-attached on
+tsys4 (via a "ThinkPad SSD" USB adapter). It is moving to a tsys5 SAS port,
+eliminating the USB bottleneck. tsys4's 4 SATA ports are all occupied (sda/sdb
+/sdc/sdd), so tsys5 is the better target. See section 3.2.
+
+### 3.2 NFS exports from tsys5 (secondary storage -- becoming the fast-tier hub)
+
+| Export | Disk model | Type | Bus | Total | Used | Free | Use% |
+|--------|-----------|------|-----|-------|------|------|------|
+| S1 | Seagate ST1000VN | HDD | SAS | 916 GB | 60 GB | 810 GB | 7% |
+| S2 | Seagate ST1000VN | HDD | SAS | 916 GB | **6.9 GB** | **863 GB** | **1%** |
+| S3 | Seagate ST1000VN | HDD | SAS | 916 GB | 7.0 GB | **863 GB** | **1%** |
+| S4 | Toshiba DT01ACA050 | HDD | SAS | 458 GB | 2 MB | **435 GB** | **0%** |
+| T5-SSD | Samsung 860 PRO | **SSD** | SAS | 234 GB | **122 GB** | **101 GB** | **55%** |
+| **D3** (Friday) | SK hynix SC300 | **SSD** | **SAS** | **469 GB** | **2 MB** | **445 GB** | **0%** |
+
+**tsys5 storage controllers (plenty of free ports):**
+- LSI SAS1068E (SAS 6/iR): 8 ports, 3 used (Samsung SSD, Hitachi, Seagate),
+  **5 free**
+- Intel ICH10 SATA #1 (4-port): 2 used (Seagate S3, Toshiba S4), **2 free**
+- Intel ICH10 SATA #2 (2-port): **status unknown, likely free**
+- 2x Renesas USB 3.0 xHCI controllers (real USB 3.0, unlike tsys6/7)
+
+**Key finding: S2 and S3 now have k8s node disks.** S2 holds cnode5 +
+wnode-tsys1 + wnode-tsys9 (6.9 GB used). S3 has wnode-tsys9's old disk
+(unused, 7 GB). S4 still 99% empty (435 GB free).
+
+T5-SSD grew to 55% used (122 GB) -- ultix-streaming is the primary consumer.
+
+**Friday additions:**
+1. **D3 (SK hynix SSD)** moves from tsys4 USB to tsys5 SAS port. Eliminates
+   USB 2.0 bottleneck. Becomes the second SSD-tier NFS export.
+2. **PCI NVMe drive** (local-only, not NFS-exported). Used for wnode-tsys5
+   boot disk and HPC scratch. The fastest tier in the fleet.
+
+After Friday, **tsys5 consolidates all fast storage**: NVMe (local) + 2 SSD
+NFS exports (D3 + T5-SSD) + 4 HDD NFS exports (S1-S4). This makes tsys5 the
+natural home for latency-sensitive workloads and the k8s StorageClass design
+center.
+
+### 3.3 Local storage tiers (per host, with utilization)
+
+| Host | Storage ID | Disk type | Bus | Total | Used | Free | Used by VMs? |
+|------|-----------|-----------|-----|-------|------|------|-------------|
+| tsys1 | local-lvm | HDD | SATA | ~90 GB | low | ~90 GB | No (all VMs on NFS) |
+| **tsys3** | **local-lvm** | **NVMe (Samsung PM961)** | **NVMe** | **349 GB** | **0 GB** | **349 GB** | **No (all VMs on NFS)** |
+| tsys4 | local-lvm | HDD | SATA | ~94 GB | PBS VM | ~62 GB | Yes (PBS VM 400) |
+| tsys5 | local-lvm | HDD (Hitachi 1.8T) | SATA | 1.7 TB | 40 MB | **1.7 TB** | No |
+| tsys5 | local-nonprod | HDD (Seagate 1T, =S1) | SATA | 916 GB | 53 GB | **856 GB** | Yes (sectestbed suite) |
+| **tsys6** | **local-lvm** | **HDD (WD My Passport)** | **USB 2.0** | **1.7 TB** | **0 GB** | **1.7 TB** | **No -- DO NOT USE for VM storage** |
+| **tsys7** | **local-lvm** | **HDD (WD portable)** | **USB 2.0** | **1.7 TB** | **0 GB** | **1.7 TB** | **No -- DO NOT USE for VM storage** |
+| **tsys9** | **local-lvm** | **SSD (PNY CS900)** | **SATA** | **136 GB** | **0 GB** | **136 GB** | **No (all VMs on NFS)** |
+| **tsys2** | **NVMe** (Samsung 960 PRO) | **NVMe** | **NVMe** | **512 GB** | (Win10) | **512 GB** | **Incoming -- fastest boot tier after tsys5 NVMe** |
+| **tsys2** | **SATA SSD** (Samsung 850 EVO) | **SSD** | **SATA** | **1 TB** | (Win10) | **1 TB** | **Incoming -- bulk data on SSD, not rust** |
+
+**CRITICAL WARNING: tsys6 and tsys7 local-lvm is USB 2.0 portable HDD.**
+
+The entire Proxmox OS, swap, and local-lvm on both R610 and R620 run on a
+single **USB 2.0-attached WD My Passport portable HDD** (tsys6: "My Passport
+260D"; tsys7: "Drive 2657"). Both servers' only USB controllers are EHCI
+(USB 2.0, ~480 Mbps). There is **no USB 3.0/xHCI** on either host.
+
+**USB 2.0 practical throughput is ~30-35 MB/s.** This is 3-4x SLOWER than
+NFS-over-HDD (~80-120 MB/s). Moving wnode boot disks to local-lvm on these
+hosts would **decrease** performance. local-lvm on tsys6/7 must NOT be used
+for VM storage.
+
+Additionally, both servers have completely empty internal drive bays:
+- **tsys6**: SAS controller present but **DISABLED** in BIOS. No internal
+drives.
+- **tsys7**: 6-port SATA AHCI controller present, **5 ports EMPTY** (only
+DVD-ROM on port 5). No internal drives.
+
+This is a reliability risk beyond performance: the entire host OS boots
+from a consumer-grade portable USB drive not designed for 24/7 server use.
+
+**tsys3 correction:** Previously documented as HDD. Actually boots from a
+**Samsung PM961 NVMe 512GB SSD** -- the fastest existing local storage in the
+fleet. Its 349 GB of local-lvm is excellent for wnode boot disk use.
+
+**Critical observation: every k8s host has 0% used local-lvm.** tsys3
+(Samsung PM961 **NVMe**, 349 GB), tsys6 (WD My Passport **USB 2.0** HDD,
+1.7 TB), tsys7 (WD portable **USB 2.0** HDD, 1.7 TB) all have unused local
+storage.
+
+**However, only tsys3's local-lvm is suitable for VM storage.** tsys6 and
+tsys7 local-lvm is USB 2.0 portable HDD (~30-35 MB/s) -- slower than
+NFS-over-HDD and unsuitable for wnode boot disks.
+
+### 3.4 Disk speed tiers summary
+
+| Tier | Where | Speed class | Best for |
+|------|-------|------------|----------|
+| **NVMe** | tsys3 (Samsung PM961), tsys5 (Friday addition), **tsys2 (Samsung 960 PRO 512GB)** | 2000-3500 MB/s | HPC scratch, ETL staging, container runtime, wnode boot, etcd |
+| **Local SSD** | tsys9 (PNY CS900, 136 GB), **tsys2 (Samsung 850 EVO 1TB)** | 500 MB/s | wnode boot disk, etcd |
+| **NFS-SSD** | tsys5 D3 (SK hynix, **SAS post-Friday**), tsys5 T5-SSD (Samsung) | 200-400 MB/s over NFS | **k8s worker scratch only** (etcd, container cache, ephemeral volumes) |
+| **NFS-HDD** | tsys4 D2/D5, tsys5 S1-S4 | 80-120 MB/s over NFS | Bulk data, large disks, non-critical VMs, **wnode boot on tsys6/7** |
+| **Local SATA HDD** | tsys1 local-lvm | 100-150 MB/s | Host OS only |
+| **USB 2.0 HDD** | tsys6/7 local-lvm (WD My Passport) | **~30-35 MB/s** | **NOTHING -- slower than NFS, do not use for VMs** |
+
+### 3.5 Storage tier characterization per host
+
+| Host | Storage profile | Detail |
+|------|----------------|--------|
+| **tsys2** | **SSD/NVMe only** | 960 PRO NVMe 512GB + 850 EVO SATA SSD 1TB. No spinning disk. |
+| **tsys3** | **NVMe only** | Samsung PM961 NVMe 512GB. No spinning disk. |
+| **tsys5** | **Hybrid** (fast-tier hub) | NVMe (local, Friday) + D3 SSD + T5-SSD + S1-S4 HDD |
+| **tsys4** | **Bulk/spinning disk only** | D2 HDD 3TB + D5 HDD 2TB. D3 SSD leaving Friday. PBS target on SMR HDD. |
+| **tsys9** | **Local SSD + NFS** | PNY CS900 SSD 136GB local + NFS client |
+| **tsys1** | **Local HDD + NFS** | Small local-lvm + NFS client |
+| **tsys6/7** | **NFS only** | local-lvm is USB 2.0 HDD (unusable for VMs). All VMs on NFS. |
+
+### 3.6 All exports are single-disk with no redundancy
+
+Every NFS export is a single physical disk formatted ext4. No RAID, no ZFS
+mirror, no mdraid. A single disk failure takes down every VM whose disk lives
+on that export. This applies to **both storage servers** and to the **PBS
+backup target** (a single 4.5T SMR drive).

+
+### 5.1 pfv-k8s cnode (control plane) placement -- CURRENT

+| Storage server | cnodes | Quorum impact if it fails |
+|---------------|--------|--------------------------|
+| tsys4 (D2+D5) | **4** (cnode1,2,3,4) | Only cnode5 survives = **QUORUM LOST** |
+| tsys5 (S2) | **1** (cnode5) | 4 survive = quorum OK |
+
+**Progress:** cnode5 is now on tsys5 (was all 5 on tsys4). But 4-of-5 on tsys4
+still means a tsys4 failure loses quorum. **Need 2 more cnodes on tsys5.**
+
+**Host distribution:** cnodes spread across 4 hosts (tsys1, tsys6, tsys7,
+tsys9) -- good host diversity.
+
+### 5.2 pfv-k8s wnode (worker) placement -- CURRENT
+
+| VMID | Name | Hypervisor | Storage | NFS Server | RAM | Status | Changed? |
+|------|------|------------|---------|-----------|-----|--------|----------|
+| 102 | wnode-tsys1 | tsys1 | S2 | tsys5 | 4 GB | **STOPPED** | **NEW** |
+| 313 | wnode-tsys3 | tsys3 | D5 | tsys4 | **28 GB** | running | **RAM bumped 20→28** |
+| 509 | wnode-tsys5 | tsys5 | D2 | tsys4 | 32 GB | running | no change |
+| 100 | wnode-tsys6 | tsys6 | D5 | tsys4 | 32 GB | running | **NOW RUNNING** |
+| 701 | wnode-tsys7 | tsys7 | D5 | tsys4 | 32 GB | running | no change |
+| 905 | wnode-tsys9 | tsys9 | **S2** | tsys5 | 4 GB | running | **Storage moved S3→S2** |
+
+**One wnode per host achieved** (tsys1,3,5,6,7,9). wnode-tsys1 is created but
+stopped. wnode-tsys6 restarted.
+
+**Storage distribution:**
+
+| Storage server | wnodes | Notes |
+|---------------|--------|-------|
+| tsys4 (D2+D5) | 4 (tsys3,5,6,7) | Still concentrated |
+| tsys5 (S2) | 2 (tsys1,tsys9) | Improving |
+
+### 5.3 Summary: k8s node storage distribution
+
+| Storage server | cnodes | wnodes | Total k8s nodes |
+|---------------|--------|--------|-----------------|
+| **tsys4 NFS** | **4 (80%)** | **4 (67%)** | **8 (73%)** |
+| **tsys5 NFS** | **1 (20%)** | **2 (33%)** | **3 (27%)** |
+| Local SSD/NVMe | 0 | 0 | 0 (0%) |
+
+**Was 90%/10%. Now 73%/27%.** Improving but still tsys4-heavy. Target: 3
+cnodes on each storage server (60/40 or better) so either server failing
+leaves quorum intact.
+
+### 5.4 Remaining cnode migration needed for etcd quorum survival
+
+To survive a tsys4 failure with quorum (3 of 5 alive), at least 3 cnodes must
+be on tsys5:
+
+| Action | Effect |
+|--------|--------|
+| Move cnode3 (D2→S3 on tsys5) | 3 cnodes on tsys5, 2 on tsys4. tsys4 fail = 3 survive |
+| Move cnode4 (D2→S2 on tsys5) | Same result, different disk |
+| Leave cnode1 and one other on tsys4 | tsys5 fail = 4 survive (OK) |
+
+**Simplest path:** migrate cnode3 and cnode4 storage to tsys5 (S3 and S2) via
+PDM. Then tsys4 failure leaves cnode5 + cnode3 + cnode4 = 3 of 5 = quorum OK.
+
+### 5.5 Future k8s architecture (next session -- see [K8S.md](K8S.md))
+
+The k8s layer will be tackled soon. Key requirements from user:
+
+- **Platform:** vcluster + Rancher for multi-tenant management
+- **Auth:** OIDC to Keycloak (running on Cloudron in Reston, VA production)
+- **Workload isolation (vcluster per tenant):**
+  - RackRental workloads (containerlab network labs)
+  - Suborbital ITAR (compliance-restricted)
+  - Suborbital non-ITAR
+  - Starting Line Productions customer workloads
+- **Solar-aware scale-out:** PowerEdge 19xx and 2950 systems (older hardware)
+  will be brought online during peak solar production for burst capacity.
+  These older cores/ram supplement the main fleet when power is abundant.
+- **WNode sizing:** every Proxmox node will have a wnode. Some nodes will host
+  both cnodes + wnodes. Worker sizes will vary from small (4 GB, fitting into
+  leftover host capacity) to large (28-32 GB, consuming most of a host).
+- **Friday final audit:** tsys2 will be loaded with Proxmox on Friday, and a
+  full final audit will be performed at that time (post-NVMe install on tsys5,
+  post-D3 SSD relocation, post-tsys4 NIC+RAM).
+
+### 5.4 sectestbed k8s nodes (separate from pfv-k8s)
+
+tsys5 also hosts a separate sectestbed kubernetes stack using local storage:
+
+| VMID | Name | Storage |
+|------|------|---------|
+| 5106 | sectestbed-k8s-cnode | local-nonprod (local HDD) |
+| 5107 | sectestbed-k8s-wnode | local-nonprod (local HDD) |
+
+These are on local storage (good -- no NFS dependency) but on a single host's
+single local disk (no redundancy). They are isolated from the pfv-k8s cluster.
+
+---
+
+## 6. Storage Redundancy Analysis
+
+### 6.1 -01/-02 infrastructure pair audit
+
+Two -01/-02 pairs exist in the fleet:
+
+**Pair 1: pfv-netinfra (network infrastructure)**
+
+| Role | VMID | Host | Storage | NFS Server |
+|------|------|------|---------|-----------|
+| -01 | 103 | tsys1 | D5 | **tsys4** |
+| -02 | 904 | tsys9 | D2 | **tsys4** |
+
+**Verdict: HOST redundancy OK (different hosts), STORAGE redundancy FAILED.**
+Both halves depend on tsys4. If tsys4 goes down, both netinfra VMs lose their
+disks. The -02 half should be on an S2/S3/S4 export from tsys5.
+
+**Pair 2: tsys-ucs (Univention Corporate Server)**
+
+| Role | VMID | Host | Storage | NFS Server |
+|------|------|------|---------|-----------|
+| -01 | 108 | tsys1 | D2 | **tsys4** |
+| -02 | 902 | tsys9 | D5 | **tsys4** |
+
+**Verdict: HOST redundancy OK (different hosts), STORAGE redundancy FAILED.**
+Same issue. Both halves on tsys4. The -02 half should be on tsys5 storage.
+
+### 6.2 Redundancy principle for paired VMs
+
+For any -01/-02 pair to survive a single storage server failure:
+
+```
+-01 VM disk -> tsys4 NFS export (D2/D3/D5)
+-02 VM disk -> tsys5 NFS export (S2/S3/S4/T5-SSD)
+```
+
+This ensures that losing either tsys4 or tsys5 takes down only one half of
+the pair. Currently, **both pairs fail this test** because both halves are on
+tsys4.
+
+### 6.3 NFS server failure blast radius
+
+If **tsys4** goes offline (USB NIC failure, disk failure, reboot):
+
+| Impact | Count |
+|--------|-------|
+| k8s cnodes that lose storage | 5 of 5 (**etcd quorum lost**) |
+| k8s wnodes that lose storage | 4 of 5 |
+| Infrastructure VMs that lose storage | 11 of 12 on tsys1 (all on D2/D5) |
+| Total VMs that lose storage | **27 of 40 (68%)** |
+
+If **tsys5** goes offline:
+
+| Impact | Count |
+|--------|-------|
+| k8s cnodes that lose storage | 0 of 5 |
+| k8s wnodes that lose storage | 1 of 5 |
+| Total VMs that lose storage | 1 of 40 (3%) |
+
+**tsys4 is a massive blast-radius liability. tsys5 is barely used.**
+Rebalancing VM storage across both servers dramatically reduces risk.
+
+---
+
+## 7. Local SSD/NVMe Opportunity
+
+### 7.1 Available fast tiers (currently unused by k8s)
+
+| Host | Device | Type | Size | Available for VMs? | Currently used by k8s? |
+|------|--------|------|------|--------------------|-----------------------|
+| tsys4 | D3 (SK hynix SC300, USB) | SSD | 512 GB | Yes (via NFS) | **No** |
+| tsys5 | T5-SSD (Samsung 860 PRO) | SSD | 256 GB | Yes (via NFS) | **No** (used by ultix-streaming) |
+| tsys5 | **New NVMe (Friday)** | **NVMe** | TBD | **Yes (local or NFS)** | **No** |
+| tsys9 | local-lvm (PNY CS900) | SSD | 137 GB free | Yes (local) | **No** |
+
+### 7.2 Why local storage matters for k8s nodes
+
+Kubernetes nodes are latency-sensitive in two specific areas:
+
+1. **etcd (control plane):** etcd writes are synchronous and latency-critical.
+   On NFS over HDD, every etcd write traverses: VM -> virtio-scsi -> NFS
+   client -> TCP -> USB dongle (on tsys4) -> ext4 -> spinning disk. Typical
+   latency: 2-10 ms per write. On local SSD: 0.1-0.5 ms. On NVMe: 0.02-0.1 ms.
+   This directly affects k8s API responsiveness and pod scheduling speed.
+
+2. **Container image pulls:** Worker nodes pull container images frequently.
+   On NFS-over-HDD, image layer extraction is seek-bound and slow. Local SSD
+   eliminates the network hop and reduces seek time. This matters most for
+   RackRental/containerlab workloads that spin up containers rapidly.
+
+### 7.3 Current waste: tsys9 local SSD
+
+tsys9 has a 250 GB PNY CS900 SSD with 137 GB of LVM-thin space available.
+**Zero VMs use it.** All 5 VMs on tsys9 boot from NFS. The local SSD sits
+idle. wnode-tsys9 (VM 905) would benefit significantly from local SSD --
+its disk is currently on S3 (tsys5 NFS over a Seagate HDD).
+
+### 7.4 Upcoming opportunity: tsys5 NVMe (Friday)
+
+The PCI NVMe being added to tsys5 will be the fastest storage tier in the
+fleet. Two placement options:
+
+**Option A: NFS-export the NVMe (shared).** All hosts can use it. Good for
+VMs that might need migration. Adds the NFS/network overhead back.
+
+**Option B: Local-only on tsys5.** VMs on tsys5 get full NVMe speed with no
+network overhead. Best for k8s wnode-tsys5 and sectestbed VMs. Cannot be
+accessed from other hosts.
+
+**Recommendation:** Option B (local-only). k8s worker nodes do not need
+shared storage -- pods are ephemeral and reschedule on failure. The NVMe
+should be formatted as a Proxmox directory storage (or LVM-thin) on tsys5
+and used for local VM images.
+
+---
+
+## 8. Role Alignment Audit
+
+Per the user's intended role taxonomy: tsys1/9 = infrastructure + k8s control
+plane; tsys2/3/6/7 = k8s workers; tsys4/5 = storage. Cnodes on tsys1/9 is
+**correct by design** (keeps heavy hosts free for workers).
+
+### 8.1 VMs that need to move
+
+| VMID | Name | Current host | Issue | Target |
+|------|------|-------------|-------|--------|
+| 509 | pfv-k8s-wnode-tsys5 | tsys5 (storage) | Worker on storage host | tsys7 or tsys2 (when online) |
+| 905 | pfv-k8s-wnode-tsys9 | tsys9 (infra) | Can stay if small; user decides | tsys9 OK if small wnode |
+
+### 8.2 Host capacity for k8s nodes
+
+| Host | Role | Current k8s nodes | k8s RAM used | RAM total | Headroom |
+|------|------|-------------------|-------------|-----------|----------|
+| tsys1 | Infra+k8s ctrl | 2 cnodes | 8 GB | 32 GB | ~12 GB (after 11 infra VMs) |
+| tsys3 | K8s worker | 1 wnode | 20 GB | 32 GB | ~12 GB |
+| tsys6 | K8s worker | 3 cnodes + 1 wnode (stopped) | 12 GB | 128 GB | **~116 GB** |
+| tsys7 | K8s worker | 1 wnode | 32 GB | 192 GB | **~160 GB** |
+| tsys9 | Infra+k8s ctrl | 1 wnode | 4 GB | 24 GB | ~12 GB (after 4 infra VMs) |
+| tsys2 | K8s worker | 0 (incoming) | 0 | 32 GB | ~32 GB |
+
+**tsys6 and tsys7 are dramatically underutilized** -- 116 GB and 160 GB of
+free RAM respectively. They should be the primary targets for heavy worker
+nodes and ETL/HPC workloads.
+
+### 8.3 tsys6 wnode-tsys6 is stopped
+
+VM 100 (pfv-k8s-wnode-tsys6) is stopped on tsys6. Its disk is on D5 (tsys4
+NFS). This wnode should be restarted (or recreated on local-lvm) to restore
+cluster capacity.
+
+---
+
+## 9. Network Findings
+
+### 9.1 tsys9 storage NIC is a USB dongle (new finding)
+
+Validating tsys9 revealed that its storage network interface
+(`enx9c69d36a5b6c`) is USB-attached (`parentbus usb`). This is the same
+anti-pattern as tsys4. The onboard Intel NIC (`enp0s31f6`) is used for
+management; storage uses the USB adapter.
+
+**Impact:** Same as tsys4 -- achieves line rate but is susceptible to cable
+wobble, ESD, and USB controller resets. For an infrastructure host with 5
+VMs, this is a reliability risk.
+
+**Mitigation:** tsys9 is an OptiPlex 7080 SFF -- it has PCIe slots. A
+PCIe NIC would eliminate this risk (same recommendation as tsys4).
+
+### 9.2 tsys4 and tsys5 still blocked (Friday hardware work)
+
+| Host | Blocker | Staged fix |
+|------|---------|-----------|
+| tsys4 | USB cdc_ncm storage NIC | PCIe NIC install + RAM upgrade (16 to 64 GB) |
+| tsys5 | bond0 broken (1 of 2 slaves) | Plug 2nd ethernet cable + apply layer3+4 hash |
+
+### 9.3 LACP resolved on tsys6/tsys7
+
+tsys6 to tsys7 storage path now measures **1.83 Gbps** (was 943 Mbps).
+The switch LACP hash change took effect after renegotiation. The 56-106K
+retransmits on this path are confirmed to be non-lossy multi-flow TCP-over-
+LACP overhead. See `RESULTS.md` (not yet created) for the full analysis.
+
+### 9.4 NFS nconnect=4 + noatime confirmed active
+
+All hosts (including tsys9) show `nconnect=4,noatime` in their NFS mount
+options. Each host maintains 4 TCP connections per NFS mount to each storage
+server. This was the Tier 0 tuning item from the performance optimization
+engagement and is confirmed working cluster-wide.
+
+---
+
+## 10. Recommendations
+
+**No changes have been made. These are assessment-only recommendations.**
+See `K8S.md` for the detailed kubernetes architecture deep-dive.
+
+### 10.1 CRITICAL: Critical infrastructure VM placement (netinfra, UCS)
+
+These are the most critical production VMs in the fleet. They must survive
+any single-point failure (host, storage server, or disk).
+
+**Design principle for -01/-02 HA pairs:**
+- Different hypervisors (already satisfied: tsys1 vs tsys9)
+- Different storage servers (currently FAILED: all on tsys4)
+- Prefer SSD for latency-sensitive services
+
+**Recommended placement:**
+
+| VM | Host | Storage | Tier | Free space | Rationale |
+|----|------|---------|------|-----------|-----------|
+| **netinfra-01** (103) | tsys1 | **D5 (tsys4 HDD)** | NFS-HDD | 1.5 TB | DNS/DHCP/NTP = minimal I/O. Stays put. |
+| **netinfra-02** (904) | tsys9 | **S3 (tsys5 HDD)** | NFS-HDD | 870 GB | Move from D2. Cross-server redundancy. Minimal I/O. |
+| **ucs-01** (108) | tsys1 | **D2 (tsys4 HDD)** | NFS-HDD | 2.4 TB | Stays put. LDAP/AD does not need SSD. |
+| **ucs-02** (902) | tsys9 | **S2 (tsys5 HDD)** | NFS-HDD | 870 GB | Move from D5. Cross-server redundancy. No SSD needed. |
+
+**Failure survival matrix (all single-point failures):**
+
+| Failure | netinfra-01 | netinfra-02 | ucs-01 | ucs-02 | Result |
+|---------|-------------|-------------|--------|--------|--------|
+| tsys4 dies | dies (D5) | **alive** (S3) | dies (D2) | **alive** (S2) | netinfra-02 + ucs-02 alive |
+| tsys5 dies | **alive** (D5) | dies (S3) | **alive** (D2) | dies (S2) | netinfra-01 + ucs-01 alive |
+| tsys1 dies | dies | **alive** | dies | **alive** | -02 pair survives |
+| tsys9 dies | **alive** | dies | **alive** | dies | -01 pair survives |
+| Any single disk | **all 4 on different disks/servers** | **all 4 alive** | | | |
+
+**Why this works:** Every row has at least one netinfra and one UCS alive.
+The network (DNS/DHCP) and directory (AD/LDAP) services never go fully dark.
+
+**D3 SSD repurposed:** With UCS staying on HDD, the D3 SSD (moving to tsys5
+Friday) is freed for latency-sensitive workloads that actually benefit from
+SSD -- sectestbed k8s nodes, CI/CD artifact cache, or a container image
+registry mirror. Not infrastructure VMs.
+
+### 10.2 CRITICAL: Cnode (control plane) storage split
+
+**Problem:** All 5 cnodes store disks on tsys4. D2 disk failure loses etcd
+quorum (3 of 5 cnodes share D2).
+
+**Target: cnodes weighted toward tsys1/tsys9 (lightweight hosts), freeing
+tsys6/tsys7 for heavy workers. Storage splits across tsys4 and tsys5.**
+
+| cnode | Current host | **Target host** | Current storage | **Target storage** | Rationale |
+|-------|-------------|----------------|----------------|-------------------|-----------|
+| cnode1 (107) | tsys1 | **tsys1** (stays) | D5 (tsys4) | **D5 (tsys4)** -- no change | Already correct |
+| cnode3 (106) | tsys1 | **tsys1** (stays) | D2 (tsys4) | **S2 (tsys5)** -- **MOVE disk** | Split storage to tsys5 |
+| cnode2 (603) | tsys6 | **tsys9** | D2 (tsys4) | **D2 (tsys4)** -- no disk change | Free tsys6 for heavy workers |
+| cnode4 (601) | tsys6 | **tsys9** | D2 (tsys4) | **D5 (tsys4)** -- spread disk | Free tsys6; spread off D2 |
+| cnode5 (602) | tsys6 | **tsys3** | D5 (tsys4) | **S3 (tsys5)** -- **MOVE disk** | Free tsys6; split storage to tsys5 |
+
+**Result after changes:**
+
+| Host | cnodes | Storage server |
+|------|--------|---------------|
+| tsys1 | cnode1 (D5), cnode3 (S2) | tsys4 + tsys5 |
+| tsys9 | cnode2 (D2), cnode4 (D5) | tsys4 |
+| tsys3 | cnode5 (S3) | tsys5 |
+
+- 3 cnodes on tsys4 storage, 2 on tsys5. Either storage server can fail and
+  etcd keeps quorum (3 of 5 survive).
+- D2 has 1 cnode (was 3). D5 has 2. S2 and S3 have 1 each. No single disk
+  holds more than 2 cnodes.
+- Cnodes now on 3 hosts (tsys1, tsys9, tsys3). Any single host failure leaves
+  at least 3 cnodes alive.
+- **tsys6 and tsys7 are fully freed** for heavy worker nodes.
+
+Note: tsys1 RAM is tight (32 GB, 11 infra VMs). Adding 0 new cnodes (keeping
+the 2 already there) is feasible with KSM. tsys9 (24 GB) has room for 2
+cnodes (8 GB). tsys3 (32 GB) has room for 1 cnode (4 GB) alongside its wnode.
+
+### 10.3 HIGH: Wnode distribution -- one per host, tiered storage
+
+**Target: one wnode per hypervisor host, using local storage where possible
+and NFS-HDD for bulk data.**
+
+| wnode | Host | Boot disk (OS+containers) | Data disk (bulk/ETL) | Rationale |
+|-------|------|--------------------------|---------------------|-----------|
+| wnode-tsys1 | tsys1 | D5 (tsys4 NFS) | -- | Small wnode on infra host. Minimal capacity. |
+| wnode-tsys3 | tsys3 | **local-lvm (349 GB NVMe)** | S3 (NFS) | Move from NFS to **NVMe** (Samsung PM961). Fastest boot disk after tsys5/2. |
+| wnode-tsys6 | tsys6 | D2 (tsys4 NFS) | -- | **Stays on NFS.** local-lvm is USB 2.0 HDD (~30 MB/s) -- slower than NFS. |
+| wnode-tsys7 | tsys7 | D5 (tsys4 NFS) | -- | **Stays on NFS.** local-lvm is USB 2.0 HDD (~30 MB/s) -- slower than NFS. |
+| wnode-tsys9 | tsys9 | **local-lvm (136 GB SSD)** | S2 (NFS) | Move from NFS to local SSD. Fast boot, NFS for bulk. |
+| wnode-tsys2 | tsys2 | **NVMe (Samsung 960 PRO 512GB)** | **SATA SSD (Samsung 850 EVO 1TB)** | **Best storage of any wnode.** No NFS needed -- 1.5 TB local SSD. |
+| wnode-tsys5 | tsys5 | **new NVMe (local)** | local-nonprod (HDD) | **Fastest wnode in fleet.** HPC/ETL workloads land here. |
+
+**Storage tiering strategy per wnode:**
+
+Each wnode gets two disk tiers mapped to k8s StorageClasses:
+
+1. **Boot + container runtime** (local-lvm or NVMe): OS, kubelet, container
+   images, ephemeral storage. This is where local SSD/NVMe shines -- container
+   image pulls and layer extraction are seek-bound and benefit enormously from
+   low-latency storage.
+
+2. **Bulk data** (NFS-HDD via D2/D5/S2/S3): weather/GIS datasets, ETL staging
+   areas, large files that do not fit on local storage. Mounted as a second
+   disk in the VM and exposed to k8s as a StorageClass.
+
+This maps to two k8s StorageClasses:
+- `local-storage`: bound to the wnode's boot/local disk (fast, ephemeral)
+- `nfs-bulk`: bound to NFS exports (slow, persistent, large capacity)
+
+### 10.4 HIGH: Dedicate D3 SSD exclusively to k8s scratch
+
+**Storage philosophy (user directive): NVMe/SSD is for k8s worker scratch
+space and ultix-streaming (developer workstation running "cluster of 1"
+pre-production jobs). Spinning rust hosts all other infrastructure VMs**
+(UCS, netinfra, LibreNMS, SIEM, etc.).
+
+SSD allocation after Friday:
+- **D3 (tsys5 SAS, 445 GB free, 0% used)** -- dedicated to k8s scratch via
+  the `nfs-ssd` StorageClass (etcd, container cache, ephemeral volumes).
+- **T5-SSD (tsys5 SAS, 140 GB free)** -- ultix-streaming (VM 5111) stays here
+  (developer workstation, runs single-node test jobs before k8s). Remaining
+  140 GB available for k8s.
+
+**Deep-dive on exact k8s scratch allocation is deferred to the next session**
+(K8S.md) once we know the k8s distribution, job scheduler, and workload mix.
+
+### 10.5 MEDIUM: Restart wnode-tsys6
+
+VM 100 (pfv-k8s-wnode-tsys6) is stopped on tsys6. Recreate on local-lvm
+(1.7 TB free) instead of D5 NFS. This restores cluster capacity and moves
+the boot disk to local storage simultaneously.
+
+### 10.6 MEDIUM: tsys5 NVMe placement (Friday)
+
+**Recommendation: local-only on tsys5, formatted as Proxmox LVM-thin or
+directory storage.**
+
+Use for:
+- wnode-tsys5 boot disk (primary beneficiary -- HPC/ETL workloads)
+- sectestbed VMs that need fast scratch space
+- Not NFS-exported (avoid adding network overhead to the fastest tier)
+
+### 10.7 LOW: Add PCIe NIC to tsys9
+
+tsys9's storage NIC is a USB dongle. tsys9 is an OptiPlex 7080 with PCIe
+slots. A $150 PCIe NIC eliminates the USB reliability risk.
+
+### 10.8 LOW: Standardize PVE/kernel versions
+
+tsys3 is on PVE kernel 7.0.14; others on 6.17.x. PVE-manager versions vary
+(9.1.1 / 9.1.5 / 9.2.5). Standardize in a maintenance window.
+

+
+## 11. Hardware End-of-Support Exposure
+
+| Host | EOS date | Years past | Form factor |
+|------|----------|-----------|-------------|
+| pfv-tsys6 (R610) | 2013-05 | 13.2 | 1U server |
+| pfv-tsys5 (T7500) | 2014-12 | 11.7 | Workstation |
+| pfv-tsys4 (T1700) | 2018-03 | 8.4 | Workstation |
+| pfv-tsys7 (R620) | 2019-03 | 7.4 | 1U server |

+| **pfv-tsys9 (7080)** | **2024-02** | **2.4** | **SFF desktop (only supported)** |
+
+**6 of 8 hosts are past vendor end-of-support.** Only tsys9 is still covered.
+The two actual rack servers (R610, R620) are the most overdue for replacement.
+This belongs in the next budget cycle.
+

+
+## 12. Open Items
+
+### 12.1 Immediate (do today via PDM)
+
+1. **Migrate ucs-02** (VM 902) from D5 (tsys4) to S2 (tsys5) for cross-server
+   redundancy. UCS stays on HDD.
+2. **Migrate netinfra-02** (VM 904) from D2 (tsys4) to S3 (tsys5).
+3. **Migrate cnode3** (VM 106) from D2 (tsys4) to S3 (tsys5) -- etcd quorum.
+4. **Migrate cnode4** (VM 601) from D2 (tsys4) to S2 (tsys5) -- etcd quorum.
+5. **Start wnode-tsys1** (VM 102) if the cluster needs the capacity.
+
+### 12.2 Friday maintenance window (user action)
+
+1. **tsys4:** Install PCIe NIC (replace USB dongle), add RAM (16 to 64 GB),
+   reconfigure `/etc/network/interfaces`, reboot.
+2. **tsys5:** Plug 2nd ethernet cable, verify bond0, apply layer3+4 hash,
+   install PCI NVMe, relocate D3 SSD from tsys4 USB to tsys5 SAS port,
+   format NVMe as local storage, reboot.
+3. **tsys2:** Load Proxmox (replacing Windows 10).
+4. **Final audit:** Re-run `deploy-check.sh` across all hosts including tsys2.
+
+### 12.3 Post-Friday validation
+
+1. Re-run iperf matrix: `./iperf-full-matrix.sh`
+2. Validate tsys4 and tsys5: `./validate-fixes.sh pfv-tsys4 && ./validate-fixes.sh pfv-tsys5`
+3. Run `scripts/check.sh` on tsys2 once Proxmox is loaded.
+4. Update PROJECT.md with post-hardware numbers.
+
+### 12.4 Future: Kubernetes deep-dive (see [K8S.md](K8S.md))
+
+Next major workstream. Requirements captured:
+- **vcluster + Rancher** for multi-tenant k8s management
+- **OIDC auth** to Keycloak (on Cloudron, Reston VA production)
+- **Workload isolation** via separate vclusters:
+  - RackRental (containerlab)
+  - Suborbital ITAR
+  - Suborbital non-ITAR
+  - Starting Line Productions customer workloads
+- **Solar-aware scale-out:** PowerEdge 19xx + 2950 systems brought online
+  during peak solar production for burst capacity
+- **Every host gets a wnode** (variable sizing: small 4 GB to large 32 GB)
+- **SSD/NVMe reserved for k8s scratch** (plus ultix-streaming exception)
+- **Spinning rust for all infrastructure VMs**
+
+### 12.5 Data gaps
+
+| Gap | How to close |
+|-----|--------------|
+| tsys5 SDR/parallel-port workload dependency | Confirm what uses the SDR |
+| tsys2 post-Proxmox baseline | Run `check.sh` after Friday install |
+| tsys5 NVMe size and model | Confirm after Friday installation |
+| tsys3 thermal state (laptop in rack) | Check `sensors` on next maintenance |
+| PowerEdge 19xx/2950 inventory | When solar scale-out is planned |
+
+### 12.6 Scripts and tools available
+
+| Script | Purpose |
+|--------|---------|
+| `scripts/check.sh` | Read-only data collector (run on hosts) |
+| `scripts/apply-tunings.sh` | Apply all Tier 0 tunings (dry-run/apply/rollback) |
+| `scripts/fix-bond-nfs.sh` | Fix NFS options + bond hash |
+| `validate-fixes.sh` | Read-only validation of all applied changes |
+| `iperf-full-matrix.sh` | Full iperf test suite (mgmt + storage) |
+| `deploy-check.sh` | Deploy check.sh to all hosts via SSH (now includes tsys9) |

+
+## 1. tsys2 Windows hardware inventory (run on the Windows host)
+
+pfv-tsys2 is currently Windows 10. Before rebuilding it as Proxmox, gather
+hardware data so the architecture plan can account for it.
+
+### Option A: PowerShell (recommended — single command, copy-paste output)
+
+Open **PowerShell as Administrator** and run:
+
+```powershell
+# Full hardware inventory in one shot
+Write-Output "=== COMPUTER ==="
+Get-CimInstance Win32_ComputerSystem | Select-Object Manufacturer, Model, SystemType, TotalPhysicalMemory | Format-List
+
+Write-Output "`n=== CPU ==="
+Get-CimInstance Win32_Processor | Select-Object Name, NumberOfCores, NumberOfLogicalProcessors, MaxClockSpeed | Format-List
+
+Write-Output "`n=== MEMORY STICKS ==="
+Get-CimInstance Win32_PhysicalMemory | Select-Object Manufacturer, PartNumber, Capacity, Speed, ConfiguredClockSpeed, DeviceLocator, FormFactor | Format-Table -AutoSize
+
+Write-Output "`n=== DISKS ==="
+Get-PhysicalDisk | Select-Object FriendlyName, MediaType, BusType, Size, SpindleSpeed | Format-Table -AutoSize
+
+Write-Output "`n=== DISK PARTITIONS ==="
+Get-Disk | Select-Object Number, FriendlyName, Size, PartitionStyle, OperationalStatus | Format-Table -AutoSize
+
+Write-Output "`n=== NETWORK ADAPTERS ==="
+Get-NetAdapter | Select-Object Name, InterfaceDescription, Status, LinkSpeed, MacAddress | Format-Table -AutoSize
+
+Write-Output "`n=== GPU(s) ==="
+Get-CimInstance Win32_VideoController | Select-Object Name, AdapterRAM, DriverVersion, VideoProcessor | Format-List
+
+Write-Output "`n=== PCIe SLOTS ==="
+Get-CimInstance Win32_SystemSlot | Select-Object SlotDesignation, CurrentUsage, Status | Format-Table -AutoSize
+
+Write-Output "`n=== USB DEVICES (storage + network only) ==="
+Get-PnpDevice -PresentOnly | Where-Object { $_.Class -in @('DiskDrive','Net','USB') } | Select-Object Class, FriendlyName, Status | Format-Table -AutoSize
+```
+
+Copy the full output into a file (e.g., `tsys2-hardware.txt`) or paste it
+directly into the chat.
+
+### Option B: Command Prompt (cmd.exe) fallbacks
+
+If PowerShell is unavailable for some reason, these cmd commands give a
+subset:
+
+```cmd
+:: Computer model and serial
+wmic computersystem get manufacturer,model
+wmic bios get serialnumber
+
+:: CPU
+wmic cpu get name,numberofcores,numberoflogicalprocessors,maxclockspeed
+
+:: RAM (total)
+wmic computersystem get totalphysicalmemory
+
+:: RAM sticks (per-slot detail)
+wmic memorychip get manufacturer,capacity,speed,partnumber,devicelocator
+
+:: Disks
+wmic diskdrive get model,size,interfacetype,mediatype
+
+:: Network adapters
+wmic nic where netenabled=true get name,speed,macaddress
+
+:: GPU
+wmic path win32_videocontroller get name,adapterram,driverversion
+```
+
+### What I'm looking for
+
+- **Disk inventory**: Are there any SSDs/NVMe available locally? (Determines
+  whether wnode-tsys2 can use local storage like the other wnodes.)
+- **Network adapters**: How many onboard NICs? Model? (Determines whether
+  tsys2 needs a USB dongle for storage network like tsys4/9, or has a real
+  onboard NIC available.)
+- **RAM layout**: Is all 32 GB in 1 stick, 2 sticks, or 4 sticks? (Affects
+  memory bandwidth for HPC workloads — dual-channel matters.)
+- **GPU detail**: Confirm the Quadro M1200 model and VRAM for passthrough
+  planning.
+- **PCIe slots**: Is there a free PCIe slot for adding a NIC or HBA?
+- **Service tag confirmation**: `GH1XZG2` (already on file from spreadsheet).
+
+### STATUS: Collected 2026-07-27
+
+**Disk inventory — RESOLVED:**
+- Disk 0: Samsung SSD 960 PRO **512 GB NVMe** (best local storage in fleet)
+- Disk 1: Samsung SSD 850 EVO **1 TB SATA SSD**
+- Both SSDs, no spinning rust. 1.5 TB total local SSD.
+
+**Network adapters — RESOLVED (concerning):**
+- StorageNetwork: **ASIX USB to Gigabit Ethernet** (dongle, D4-81-D7-3E-0D-5E)
+- Ethernet: **Realtek USB GbE Family Controller** (also USB, 18-FD-CB-00-D2-CA)
+- Wi-Fi: Intel 8265 (disconnected)
+- **Both wired NICs are USB-attached.** Same anti-pattern as tsys4/9.
+  Unavoidable on this laptop form factor — no onboard PCIe NIC available.
+
+**GPU — RESOLVED:**
+- Intel HD Graphics 630 (integrated, 1 GB)
+- NVIDIA Quadro M1200 (4 GB, confirmed for passthrough)
+
+**PCIe slots — RESOLVED:**
+- Slots 3/6/7/8 report "Available" but these are laptop M.2/WWAN slots, not
+  user-accessible full PCIe. **Cannot add a PCIe NIC.** NVMe slot occupied
+  by 960 PRO.
+
+**RAM — PARTIAL:**
+- Total 32 GB confirmed (34,097,573,888 bytes).
+- Per-stick detail failed to run (PowerShell line-break split
+  `Format-T` + `able`). Re-run the command below if bandwidth planning
+  needs stick-level detail:
+  ```powershell
+  Get-CimInstance Win32_PhysicalMemory | Select-Object Manufacturer, PartNumber, Capacity, Speed, ConfiguredClockSpeed, DeviceLocator, FormFactor | Format-Table -AutoSize
+  ```
+
+**Service tag — CONFIRMED:** `GH1XZG2` (Precision 5520).
+
+---
+
+## 2. Friday maintenance window (physical hardware)
+
+### tsys4 — install PCIe NIC + add RAM
+
+1. Power down tsys4 (graceful shutdown via Proxmox UI or `shutdown -h now`).
+2. Install the **PCIe NIC** (Intel i350-T2 or similar 1 GbE dual-port).
+3. Add **RAM**: 16 GB → 64 GB DDR3 ECC.
+4. Power on, then update `/etc/network/interfaces` to replace
+   `enx8cae4ccda926` (USB dongle) with the new PCIe NIC device name.
+5. Reboot to activate new NIC and NFS nconnect.
+6. Run `validate-fixes.sh pfv-tsys4` to confirm.
+
+### tsys5 — plug storage cable + install NVMe + relocate D3 SSD
+
+1. Plug the **second ethernet cable** into tsys5's dedicated storage NIC.
+2. Verify bond0 recovery: `cat /proc/net/bonding/bond0` — look for
+   "Number of ports: 2" and a real partner MAC (not all zeros).
+3. Apply bond hash fix (same as tsys6/7):
+   ```bash
+   echo "layer3+4" > /sys/class/net/bond0/bonding/xmit_hash_policy
+   ```
+4. **Relocate D3 SSD** from tsys4 USB to tsys5 SAS port:
+   - Power down tsys4
+   - Remove the SK hynix SC300 SSD from its USB enclosure on tsys4
+   - Install it on a free SAS port on tsys5 (5 ports free on LSI SAS1068E)
+   - On tsys5: mount as `/mnt/pfv-tsys5/D3`, add to `/etc/exports`
+   - Update `/etc/pve/storage.cfg` cluster-wide: repoint D3 `server` from
+     `pfv-tsys4-nfs-stor` to `pfv-tsys5-nfs-stor`, update `export` path
+   - Copy any existing D3 data from tsys4 first (currently ~2 MB, essentially
+     empty, so minimal migration)
+5. Install the **PCI NVMe drive** (uses a PCI slot, not a SATA/SAS port).
+6. Format NVMe as local directory storage (see TODO section 3 below).
+7. Reboot tsys5 to activate NFS nconnect.
+8. Run `validate-fixes.sh pfv-tsys5` to confirm.
+
+---
+
+## 3. tsys5 NVMe format/mount decision (after Friday install)
+
+**Recommendation: local-only, not NFS-exported.** Format as Proxmox directory
+storage so it shows up as a VM image target in the Proxmox UI.
+
+After the NVMe is physically installed and visible in Proxmox:
+
+1. Identify the device: `lsblk` or `ls /dev/nvme*`
+2. Format and add to Proxmox:
+   ```bash
+   # Option A: LVM-thin (thin provisioning, snapshots)
+   pvcreate /dev/nvme0n1
+   vgcreate nvme-pool /dev/nvme0n1
+   lvcreate -l 100%FREE -T nvme-pool/data
+   # Then in Proxmox UI: Datacenter > Storage > Add > LVM-Thin
+   #   ID: nvme-local
+   #   Volume Group: nvme-pool
+   #   Thin Pool: data
+   #   Content: Disk image, Container template
+
+   # Option B: Directory (simpler, no thin provisioning)
+   mkfs.ext4 /dev/nvme0n1
+   mkdir -p /mnt/nvme
+   mount /dev/nvme0n1 /mnt/nvme
+   # Add to /etc/fstab for persistence
+   # Then in Proxmox UI: Datacenter > Storage > Add > Directory
+   #   ID: nvme-local
+   #   Directory: /mnt/nvme
+   #   Content: Disk image, Container template
+   ```
+
+3. Use for wnode-tsys5 boot disk (highest impact) and sectestbed VM scratch.
+
+---
+
+## 4. Post-hardware validation (run after Friday work)
+
+1. Re-run iperf matrix: `./iperf-full-matrix.sh`
+2. Validate tsys4 and tsys5: `./validate-fixes.sh pfv-tsys4 && ./validate-fixes.sh pfv-tsys5`
+3. Update PROJECT.md with post-hardware iperf numbers.
+
+---
+
+## 5. UCS storage migration to spinning disk (do today)
+
+UCS (Univention Corporate Server / open-source AD) does not need SSD. Both
+UCS VMs should stay on spinning disk (HDD) and be split across storage
+servers for redundancy.
+
+| VM | Current | Target | Action |
+|----|---------|--------|--------|
+| ucs-01 (108) | D2 (tsys4 HDD) | **D2 (tsys4 HDD) -- no change** | Already correct |
+| ucs-02 (902) | D5 (tsys4 HDD) | **S2 (tsys5 HDD)** | Move for cross-server redundancy |
+
+**To migrate ucs-02 to S2 (use PDM/Proxmox UI):**
+1. In Proxmox Datacenter or the node UI, select VM 902 on tsys9
+2. Use "Migrate" or "Storage Migrate" to move the disk from D5 to S2
+   (both are NFS exports visible to tsys9, so this is a storage-only migration)
+3. Verify VM 902 boots and LDAP/AD services are healthy after migration
+
+Note: both VMs are currently on tsys4 HDD, which is fine for UCS. Only
+ucs-02 needs to move -- it should be on a different storage server than
+ucs-01 so a tsys4 failure doesn't take down both halves of the AD pair.
+
+---
+
+## 6. Open questions for next session
+
+- Are the hosts a Proxmox cluster (`pvecm status`) or standalone installs?
+  Determines whether live migration is available.
+- What k8s distribution is in use? (k3s, kubeadm, RKE2?)
+- Container runtime? (containerd, cri-o?)
+- Is there a local container image registry mirror?
+- What specific ETL tools? (GDAL, PostGIS, xarray, Dask?)
+- HPC job scheduler? (plain k8s Jobs, Argo Workflows, Volcano?)
+- What uses tsys5's SDR + parallel port before planning tsys5 role changes?
+- tsys3 thermal state (laptop in rack for years) — check `sensors`.

+# TSYS PFVCluster Development Guidelines
 
-> **Documentation moved to Discourse — the canonical source of truth.**
->
-> **Coding standards, commit conventions, script patterns**
->
-> **Read it here:** https://community.turnsys.com/t/302
->
-> *Migrated 2026-08-06. This file is kept as a pointer for git-browsing context.

+## Overview
+
+This document contains development standards and best practices for the TSYS PFVCluster infrastructure provisioning system.
+
+## Package Management Best Practices
+
+### Combine apt-get Install Commands
+
+**Rule:** Always combine multiple package installations into a single `apt-get install` command for performance.
+
+**Rationale:** Single command execution is significantly faster than multiple separate commands due to:
+- Reduced package cache processing
+- Single dependency resolution
+- Fewer network connections
+- Optimized package download ordering
+
+#### ✅ Correct Implementation
+```bash
+# Install all packages in one command
+apt-get install -y package1 package2 package3 package4
+
+# Real example from 2FA script
+apt-get install -y libpam-google-authenticator qrencode
+```
+
+#### ❌ Incorrect Implementation
+```bash
+# Don't use separate commands for each package
+apt-get install -y package1
+apt-get install -y package2
+apt-get install -y package3
+```
+
+#### Complex Package Installation Pattern
+```bash
+function install_security_packages() {
+    print_info "Installing security packages..."
+    
+    # Update package cache once
+    apt-get update
+    
+    # Install all packages in single command
+    apt-get install -y \
+        auditd \
+        fail2ban \
+        libpam-google-authenticator \
+        lynis \
+        rkhunter \
+        aide \
+        chkrootkit \
+        clamav \
+        clamav-daemon
+    
+    print_success "Security packages installed successfully"
+}
+```
+
+## Script Development Standards
+
+### Error Handling
+- Always use `set -euo pipefail` at script start
+- Implement proper error trapping
+- Use framework error handling functions
+- Return appropriate exit codes
+
+### Function Structure
+```bash
+function function_name() {
+    print_info "Description of what function does..."
+    
+    # Local variables
+    local var1="value"
+    local var2="value"
+    
+    # Function logic
+    if [[ condition ]]; then
+        print_success "Success message"
+        return 0
+    else
+        print_error "Error message"
+        return 1
+    fi
+}
+```
+
+### Framework Integration
+- Source framework includes at script start
+- Use framework logging and pretty print functions
+- Follow existing patterns for consistency
+- Include proper PROJECT_ROOT path resolution
+
+```bash

->
-> **End-user guide for 2FA setup**
->
-> **Read it here:** https://community.turnsys.com/t/303
->
-> *Migrated 2026-08-06. This file is kept as a pointer for git-browsing context.

+## Overview
+
+This guide provides complete instructions for implementing and managing two-factor authentication (2FA) on TSYS servers using Google Authenticator (TOTP).
+
+## What This Implementation Provides
+
+### Services Protected by 2FA
+- **SSH Access:** Requires SSH key + 2FA token
+- **Cockpit Web Interface:** Requires password + 2FA token
+- **Webmin Administration:** Requires password + 2FA token (if installed)
+
+### Security Features
+- **Time-based One-Time Passwords (TOTP):** Standard 6-digit codes
+- **Backup Codes:** Emergency access codes
+- **Gradual Rollout:** Optional nullok mode for phased deployment
+- **Configuration Backup:** Automatic backup of all configs
+
+## Implementation Steps
+
+### Step 1: Run the 2FA Setup Script
+```bash
+# Navigate to the security modules directory
+cd provisioning/Modules/Security
+
+# Run the 2FA setup script as root
+sudo bash secharden-2fa.sh
+```
+
+### Step 2: Validate Installation
+```bash
+# Run 2FA validation tests
+./Project-Tests/security/2fa-validation.sh
+
+# Run specific 2FA security test
+./Project-Tests/run-tests.sh security
+```
+
+### Step 3: Setup Individual Users
+For each user that needs 2FA access:
+
+```bash
+# Check setup instructions
+cat /home/username/2fa-setup-instructions.txt
+
+# Run user setup script
+sudo /tmp/setup-2fa-username.sh
+```
+
+### Step 4: Test 2FA Access
+1. **Test SSH access** from another terminal
+2. **Test Cockpit access** via web browser
+3. **Test Webmin access** if installed
+
+## User Setup Process
+
+### Installing Authenticator Apps
+Users need one of these apps on their phone:
+- **Google Authenticator** (Android/iOS)
+- **Authy** (Android/iOS)
+- **Microsoft Authenticator** (Android/iOS)
+- **1Password** (with TOTP support)
+
+### Setting Up 2FA for a User
+1. **Run setup script:**
+   ```bash
+   sudo /tmp/setup-2fa-username.sh
+   ```
+
+2. **Follow prompts:**
+   - Answer "y" to update time-based token
+   - Scan QR code with authenticator app
+   - Save emergency backup codes securely
+   - Answer "y" to remaining security questions
+
+3. **Test immediately:**
+   ```bash
+   # Test SSH from another terminal
+   ssh username@server-ip
+   # You'll be prompted for 6-digit code
+   ```
+
+## Configuration Details
+
+### SSH Configuration Changes
+File: `/etc/ssh/sshd_config`
+```
+ChallengeResponseAuthentication yes
+UsePAM yes
+AuthenticationMethods publickey,keyboard-interactive
+```
+
+### PAM Configuration
+File: `/etc/pam.d/sshd`
+```
+auth required pam_google_authenticator.so nullok
+```
+
+### Cockpit Configuration
+File: `/etc/cockpit/cockpit.conf`
+```
+[WebService]
+LoginTitle = TSYS Server Management
+LoginTo = 300
+RequireHost = true
+
+[Session]
+Banner = /etc/cockpit/issue.cockpit
+IdleTimeout = 15
+```
+
+### Webmin Configuration
+File: `/etc/webmin/miniserv.conf`
+```
+twofactor_provider=totp
+twofactor=1
+```
+
+## Security Considerations
+
+### Gradual vs Strict Enforcement
+
+#### Gradual Enforcement (Default)
+- Uses `nullok` option in PAM
+- Users without 2FA can still log in
+- Allows phased rollout
+- Good for initial deployment
+
+#### Strict Enforcement
+- Remove `nullok` from PAM configuration
+- All users must have 2FA configured
+- Immediate security enforcement
+- Risk of lockout if misconfigured
+
+### Backup and Recovery
+
+#### Emergency Access
+- **Backup codes:** Generated during setup
+- **Root access:** Can disable 2FA if needed
+- **Console access:** Physical/virtual console bypasses SSH
+
+#### Configuration Backup
+- Automatic backup to `/root/backup/2fa-TIMESTAMP/`
+- Includes all modified configuration files
+- Can be restored if needed
+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. User Cannot Generate QR Code
+```bash
+# Ensure qrencode is installed
+sudo apt-get install qrencode
+
+# Re-run user setup
+sudo /tmp/setup-2fa-username.sh
+```
+
+#### 2. SSH Connection Fails
+```bash
+# Check SSH service status
+sudo systemctl status sshd
+
+# Test SSH configuration
+sudo sshd -t
+
+# Check logs
+sudo journalctl -u sshd -f
+```
+
+#### 3. 2FA Code Not Accepted
+- **Check time synchronization** on server and phone
+- **Verify app setup** - rescan QR code if needed
+- **Try backup codes** if available
+
+#### 4. Locked Out of Server
+```bash
+# Access via console (physical/virtual)
+# Disable 2FA temporarily
+sudo cp /root/backup/2fa-*/pam.d.bak/sshd /etc/pam.d/sshd
+sudo systemctl restart sshd
+```
+
+### Debug Commands
+
+```bash
+# Check 2FA status
+./Project-Tests/security/2fa-validation.sh
+
+# Check SSH configuration
+sudo sshd -T | grep -E "(Challenge|PAM|Authentication)"
+
+# Check PAM configuration
+cat /etc/pam.d/sshd | grep google-authenticator
+
+# Check user 2FA status
+ls -la ~/.google_authenticator
+```
+
+## Management and Maintenance
+
+### Adding New Users
+1. Ensure user account exists
+2. Run setup script for new user
+3. Provide setup instructions
+4. Test access
+
+### Removing User 2FA
+```bash
+# Remove user's 2FA configuration
+sudo rm /home/username/.google_authenticator
+
+# User will need to re-setup 2FA
+```
+
+### Disabling 2FA System-Wide
+```bash
+# Restore original configurations
+sudo cp /root/backup/2fa-*/sshd_config.bak /etc/ssh/sshd_config
+sudo cp /root/backup/2fa-*/pam.d.bak/sshd /etc/pam.d/sshd
+sudo systemctl restart sshd
+```
+
+### Updating 2FA Configuration
+```bash
+# Re-run setup script
+sudo bash secharden-2fa.sh
+
+# Validate changes
+./Project-Tests/security/2fa-validation.sh
+```
+
+## Best Practices
+
+### Deployment Strategy
+1. **Test in non-production** environment first
+2. **Enable gradual rollout** (nullok) initially
+3. **Train users** on 2FA setup process
+4. **Test emergency procedures** before strict enforcement
+5. **Monitor logs** for authentication issues
+
+### Security Recommendations
+- **Enforce strict mode** after successful rollout
+- **Regular backup code rotation**
+- **Monitor failed authentication attempts**
+- **Document emergency procedures**
+- **Regular security audits**
+
+### User Training
+- **Provide clear instructions**
+- **Demonstrate setup process**
+- **Explain backup code importance**
+- **Test login process with users**
+- **Establish support procedures**
+
+## Monitoring and Logging
+
+### Authentication Logs
+```bash
+# SSH authentication logs
+sudo journalctl -u sshd | grep -i "authentication"
+
+# PAM authentication logs
+sudo journalctl | grep -i "pam_google_authenticator"
+
+# Failed login attempts
+sudo journalctl | grep -i "failed"
+```
+
+### Security Monitoring
+- Monitor for repeated failed 2FA attempts
+- Alert on successful logins without 2FA (during gradual rollout)
+- Track user 2FA setup completion
+- Monitor for emergency access usage
+
+## Integration with Existing Systems
+
+### LDAP/Active Directory
+- 2FA works with existing authentication systems
+- Users still need local 2FA setup
+- Consider centralized 2FA solutions for large deployments
+
+### Monitoring Systems
+- LibreNMS: Will continue to work with SNMP
+- Wazuh: Will log 2FA authentication events
+- Cockpit: Enhanced with 2FA protection
+
+### Backup Systems
+- Ensure backup procedures account for 2FA
+- Test restore procedures with 2FA enabled
+- Document emergency access procedures
+
+## Support and Resources
+
+### Files Created by Setup
+- `/tmp/setup-2fa-*.sh` - User setup scripts
+- `/home/*/2fa-setup-instructions.txt` - User instructions
+- `/root/backup/2fa-*/` - Configuration backups
+
+### Validation Tools
+- `./Project-Tests/security/2fa-validation.sh` - Complete 2FA validation
+- `./Project-Tests/run-tests.sh security` - Security test suite
+
+### Emergency Contacts
+- System Administrator: [Contact Info]
+- Security Team: [Contact Info]
+- 24/7 Support: [Contact Info]
+
+## Compliance and Audit
+
+### Security Benefits

+# Tailscale vs. Managed DNS — Architecture Analysis
 
-> **Documentation moved to Discourse — the canonical source of truth.**
->
-> **Tailscale vs managed DNS analysis (resolved)**
->
-> **Read it here:** https://community.turnsys.com/t/306
->
-> *Migrated 2026-08-06. This file is kept as a pointer for git-browsing context.
-> Do not update content here — edit the Discourse wiki topic instead.*
+> **Status:** **RESOLVED.** The pfv-netinfra-01/02 pair now runs production
+> Technitium DNS with all `knel.net` records replicated from tailscale-router
+> via the DNS cluster setup. Both LAN IPs serve authoritative records for
+> `knel.net` and recurse externally. This document records the original
+> conflict, how it was resolved, and the recommended client configuration.
+
+## 1. Executive summary
+
+Every host in this build runs the Tailscale client, and Tailscale's MagicDNS
+manages `/etc/resolv.conf` by default (pointing at `100.100.100.100`). This
+previously conflicted with a managed `resolv.conf` pointing at the LAN
+resolvers. The root cause was that the LAN Technitium instances did not have
+the `knel.net` zone populated — **that is now fixed.**
+
+The pfv-netinfra-01/02 pair now serves identical, authoritative `knel.net`
+records (replicated from production via [`dns-cluster-setup/`](../dns-cluster-setup/README.md)).
+Both LAN IPs resolve `knel.net` device names and recurse externally. The
+managed `resolv.conf` is now safe to deploy.
+
+**Recommendation:** Deploy the managed `resolv.conf` (`.252`/`.253`) on hosts
+where you want tunnel-independent DNS. Leave Tailscale managing DNS on hosts
+where MagicDNS device names must resolve without a LAN path (e.g. laptops off
+-network). See [§5](#5-recommendation) for details.
+
+## 2. How name resolution works today (post-cluster-setup)
+
+Probed from `sectestbed-sandbox` (192.168.3.50) after the DNS cluster was
+deployed:
+
+| Query path | External name (`github.com`) | `knel.net` device name (`pfv-netinfra-01.knel.net`) |
+|---|---|---|
+| Via Tailscale resolver (`100.100.100.100`) | resolves | resolves → `100.70.181.72` (Tailscale CGNAT) |
+| Direct `dig @192.168.3.252` (Technitium primary, LAN) | resolves (recurses) | **resolves** → `100.70.181.72` |
+| Direct `dig @192.168.3.253` (Technitium secondary, LAN) | resolves (recurses) | **resolves** → `100.70.181.72` |
+
+**Both LAN resolvers now serve `knel.net` records identically.** The
+Technitium zone is no longer stale — it was replicated from production
+(tailscale-router) as part of the DNS cluster setup.
+
+### What changed
+
+Previously (before the DNS cluster setup), querying the LAN IPs returned
+NXDOMAIN for `knel.net` device names because the Technitium `knel.net` zone
+was empty (SOA serial `2025062313`, dated 2025-06-23). After replicating
+production config to both netinfra hosts, all 124 zones — including
+`knel.net` with all current device records — are served authoritatively on
+both `.252` and `.253`.
+
+## 3. The DNS server pair
+
+| Host | IP | Role | Services |
+|------|----|------|----------|
+| pfv-netinfra-01 | 192.168.3.252 | **Primary** | Technitium (authoritative, port 5300) + Pi-hole (recursive, port 53) |
+| pfv-netinfra-02 | 192.168.3.253 | **Secondary** | Technitium (replicated via rsync, port 5300) + Pi-hole (recursive, port 53) |
+
+Zone replication is rsync-based (every 60s via systemd timer) because
+Technitium's AXFR uses port 53, which is occupied by Pi-hole on these hosts.
+See [`dns-cluster-setup/README.md`](../dns-cluster-setup/README.md) for
+full details.
+
+## 4. NTP (fully resolved)
+
+NTP is independent of DNS: `provisioning/ConfigFiles/NTP/ntp.conf` points
+directly at the LAN IPs with no DNS dependency:
+
+```
+server 192.168.3.252 iburst
+server 192.168.3.253 iburst
+```
+
+Both servers respond with stratum 2/3. The client config uses `restrict`
+rules (not `interface listen`) to avoid the loopback-binding bug that
+prevented sync. This is safe under both Tailscale-managed and LAN-pinned
+resolver configurations.
+
+## 5. Recommendation
+
+### On fixed servers (always on-LAN)
+
+**Deploy the managed `resolv.conf`** (`provisioning/ConfigFiles/Resolv/`):
+- Points at `.252`/`.253` with failover
+- `knel.net` records resolve on both servers
+- External names recurse on both servers
+- DNS survives `tailscaled` outages (unlike Tailscale-managed DNS)
+
+To prevent Tailscale from overwriting the managed file:
+```bash
+tailscale up --accept-dns=false
+```
+
+### On laptops / roaming hosts
+
+**Let Tailscale manage DNS** (default `accept-dns=true`):
+- MagicDNS resolves `knel.net` device names via the tunnel
+- No dependency on LAN reachability
+- Accept the `tailscaled` dependency (if the tunnel is down, you're off-network anyway)
+
+## 6. Known items / future work
+
+1. **Pi-hole upstream configuration.** Pi-hole on both hosts should forward
+   to the local Technitium instance (port 5300) for `knel.net` and to an
+   external resolver for everything else. Verify this is configured on both
+   nodes.
+2. **Zone transfer via AXFR.** Currently using rsync because Technitium's
+   AXFR expects port 53. If Technitium's listen port can be changed, or
+   Pi-hole can be configured to proxy AXFR, the rsync timer could be
+   replaced with native DNS zone transfer.
+3. **`accept-dns=false` automation.** The provisioning code should set
+   `--accept-dns=false` on Tailscale during setup (after deploying the
+   managed `resolv.conf`) so Tailscale doesn't overwrite it on reboot.

->

+Scripts to bootstrap and manage the k3s control plane on cnode1/2/3.
+All cluster communication goes over Tailscale IPs — no LAN traffic.
+
+## Current State
+
+3-node HA control plane (k3s v1.36.2+k3s1, embedded etcd):
+
+| Node | Tailscale IP | Role | Tainted |
+|------|-------------|------|---------|
+| pfv-k8s-cnode1 | 100.97.178.106 | control-plane, etcd | NoSchedule |
+| pfv-k8s-cnode2 | 100.109.34.72 | control-plane, etcd | NoSchedule |
+| pfv-k8s-cnode3 | 100.106.222.18 | control-plane, etcd | NoSchedule |
+
+## Scripts
+
+| Script | Purpose |
+|--------|---------|
+| [`env.sh`](env.sh) | Shared config: node IPs, SSH opts, k3s version. Sourced by all scripts. |
+| [`wipe.sh`](wipe.sh) | Remove existing k3s from all cnodes (clean slate). |
+| [`install-cp.sh`](install-cp.sh) | Full bootstrap: cnode1 (--cluster-init) then cnode2/3 join. |
+| [`join-servers.sh`](join-servers.sh) | Re-join cnode2/3 only (if cnode1 is already up). |
+| [`post-setup.sh`](post-setup.sh) | Apply NoSchedule taints, fetch kubeconfig, verify. |
+| [`verify.sh`](verify.sh) | Health check: nodes Ready, Tailscale IPs, taints, etcd, CoreDNS. |
+| [`probe-nodes.sh`](probe-nodes.sh) | Verify SSH + Tailscale reachability. |
+
+## Usage
+
+```bash
+# Full bootstrap from scratch:
+bash k8s/wipe.sh
+bash k8s/install-cp.sh
+bash k8s/post-setup.sh
+bash k8s/verify.sh
+
+# Access the cluster:
+export KUBECONFIG=~/.kube/config.pfv-k8s
+kubectl get nodes
+```
+
+## Design Decisions
+
+- **k3s (not Talos):** This is a regular R&D cluster, not ITAR/classified.
+  Talos architecture is documented in [`docs/k8s/`](../docs/k8s/) for when
+  that requirement comes online. k3s on stock Debian is simpler to operate.
+- **Tailscale-only transport:** `--node-ip`, `--advertise-address`, and
+  `--tls-san` are all set to Tailscale IPs. No LAN IP appears in any node
+  status or certificate.
+- **VXLAN flannel:** Pods communicate via flannel VXLAN overlay on top of
+  Tailscale's WireGuard. Double-encrypted, but functional and reliable.
+- **NoSchedule taint:** All 3 cnodes are tainted so no user workloads
+  schedule on the control plane. Only system components (CoreDNS,
+  metrics-server, flannel, kube-proxy) with built-in tolerations run here.
+- **Embedded etcd:** 3-node HA etcd quorum. Tolerates 1 node failure.

+## 1. Host
+
+| Item | Value |
+|---|---|
+| Hostname / FQDN | `pfv-netboot` / `pfv-netboot.knel.net` |
+| OS | Debian GNU/Linux 12 (bookworm), kernel 6.1.0-44-amd64 |
+| Hardware | 2 vCPU, ~1.9 GiB RAM, 491 GB disk (18 GB used) |
+| Timezone | `America/Chicago` (US/Central) |
+| LAN | `eth0` static `192.168.3.250/22`, gw `192.168.3.254` (`/etc/network/interfaces`) |
+| Tailscale | `100.103.64.82` (`tailscale0`) |
+| DNS resolver | Tailscale MagicDNS — `/etc/resolv.conf` → `100.100.100.100` |
+| Docker | Docker Engine 29.6.2 (containerd v2.2.6, runc 1.3.6) |
+| Access | `localuser` has passwordless sudo; **not** in `docker` group (uses `sudo docker`) |
+
+`eth1` is up but unconfigured; many docker bridges exist (`pihole_default`,
+`ntp_default`, `dns_default`, and several stale ones).
+
+## 2. Services overview
+
+| Service | Form | Running? |
+|---|---|---|
+| **Pi-hole** (DNS sinkhole, recursive resolver) | Docker container `pihole` | ✅ healthy |
+| **NTP** — overlay on Tailscale IP | Docker container `tsys-ntp` (`dockurr/chrony`) | ✅ healthy |
+| **NTP** — system clock + LAN serving | bare-metal `ntpsec` (`ntpd`) | ✅ active, enabled |
+| **Technitium DNS** (authoritative for `knel.net`) | Docker container | ❌ **not running**; config preserved in orphaned volume |
+
+## 3. Pi-hole (container)
+
+- **Compose:** `/root/pihole/docker-compose.yml` (compose project `pihole`)
+- **Image:** `pihole/pihole:latest` — Core **v6.1.2**, Web v6.2.1, FTL v6.2.2
+- **Container:** `pihole`, `restart: always`, `cap_add: [SYS_NICE]`, network `pihole_default`
+- **Ports (host):**
+
+  | Host | Container | Purpose |
+  |---|---|---|
+  | `53/tcp`, `53/udp` | 53 | DNS |
+  | `10002/tcp` | 80 | Web admin (HTTP) |
+  | `10003/tcp` | 443 | Web admin (HTTPS, self-signed) |
+
+- **Environment:** `TZ=America/Chicago`, `FTLCONF_webserver_api_password=Gransyan1!`, `FTLCONF_dns_listeningMode=all`
+- **Data:** bind mount `/root/pihole/etc-pihole:/etc/pihole` (dir owned by `localuser`; files by container `pihole` uid)
+- **Config (Pi-hole v6 TOML):** `pihole.toml`. Key settings:
+  - Upstream DNS: `192.168.3.16`, `8.8.8.8`, `2001:4860:4860::8888`
+  - `listeningMode = "ALL"`, `interface = "eth0"`, `dns.port = 53`, `dns.domain = "lan"`
+  - `queryLogging = true`, DNSSEC off
+- **Adlists:** one entry — `https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts` (in `gravity.db`/`adlists.list`)
+- **Gravity DB:** `/etc/pihole/gravity.db` (~5.5 MB) holds adlists/domainlists/clients/groups
+- **Web admin:** `http://pfv-netboot:10002/admin/` (password `Gransyan1!`)
+- Note: query history `pihole-FTL.db` (~2.5 GB) is transient and **excluded** from replication.
+
+## 4. NTP (two layers)
+
+### 4a. chrony container (`tsys-ntp`) — overlay on the Tailscale IP
+- **Compose:** `/root/NTP/docker-compose.yml` (project `ntp`)
+- **Image:** `dockurr/chrony`
+- **Env:** `NTP_SERVERS=pool.ntp.org`
+- **Ports:** `100.103.64.82:123:123/udp` — bound specifically to the **Tailscale IP**
+- `restart: always`
+- chrony.conf (generated): `server pool.ntp.org iburst`, `allow all`, `rtcsync`
+- On netboot this coexists with bare-metal ntpsec because ntpsec here does **not** pre-bind the specific Tailscale-IP socket, letting Docker claim it.
+
+### 4b. bare-metal `ntpsec`
+- Unit `ntpsec.service` — active, enabled; `/usr/sbin/ntpd -c /etc/ntpsec/ntp.conf -g -N -u ntpsec:ntpsec`
+- **Config** (`/etc/ntpsec/ntp.conf`):
+  ```
+  driftfile /var/lib/ntp/ntp.drift
+  leapfile /usr/share/zoneinfo/leap-seconds.list
+  server pfvsvrpi.knel.net
+  restrict 127.0.0.1
+  restrict ::1
+  ```
+- Listens on all local addresses (incl. Tailscale) for UDP/123; serves LAN clients.
+
+## 5. Technitium DNS (currently stopped)
+
+- **Not running** — no container and **no compose file** exists for it.
+- A previous deployment left an **orphaned Docker volume** `dns_tsys-dns-config`
+  (mountpoint `/var/lib/docker/volumes/dns_tsys-dns-config/_data`) whose contents
+  are intact (last activity 2025-06-23). A second typo'd volume
+  `dns_tyss-dns-config` is empty.
+- Config files are **binary** (Technitium's own serialization), but copy verbatim:
+  `dns.config`, `auth.config`, `log.config`, `scopes/Default.scope`,
+  `self-signed-cert.pfx`, `cache.bin`, `zones/`, `stats/`, `logs/`.
+- **Zones present** (12 reverse + 1 forward):
+  - `knel.net.zone` — forward zone; SOA `dns.knel.net. hostadmin.knel.net.` (serial `2025062313`). A-records for the internal fleet, including: `tsys1`, `rr-middleware`, `pfv-netboot`, `pfv-k8s-cnode1`…`cnode5`, `pfv-k8s-wnode3`, `tsys-k8scloud-netcup-1`, `tsys-kali-vptechops`, `tsys-kali-dev`; NS `dns.knel.net`.
+  - Reverse zones for Tailscale CGNAT ranges (`100.x.in-addr.arpa`): `199.86`, `145.105`, `181.103`, `184.108`, `194.67`, `2.108`, `211.114`, `46.96`, `64.103`, `75.110`, `97.82`, `119.127`.
+- **Auth:** `auth.config` defines user `admin` (Administrators group) with a stored password hash; the plaintext password is whatever was set on the original Technitium instance.
+- The compose project name historically was `dns` (network `dns_default` still exists).
+
+## 6. Firewall / misc
+
+- nftables/iptables: mostly Docker + Tailscale chains (`ts-input`, `ts-forward`,
+  `DOCKER`, `DOCKER-FORWARD`); default `INPUT ACCEPT`, `FORWARD DROP`,
+  `OUTPUT ACCEPT`. No UFW / firewalld.
+- Also runs (out of scope for this replication): Samba (137/138/139, 445), NFS
+  (2049), rpcbind (111), Postfix (25), Cockpit (9090), Beszel agent, webmin/
+  usermin (10000/10002/20000), Tailscale (41641).
+- SELinux absent; AppArmor default docker profile.
+
+## 7. How it was audited (no changes made)

+(Pi-hole, Technitium DNS, NTP). They were deployed by `setup-netinfra.sh`, which
+reads config from pfv-netboot (read-only) and relays it to each target.
+

+## 3. Pi-hole (container `pihole`)
+
+Image `pihole/pihole:latest`; `restart: always`; `cap_add: [SYS_NICE]`.
+
+| Host port | Container | Purpose |
+|---|---|---|
+| `53/tcp`, `53/udp` | 53 | DNS (the LAN/Tailscale recursive resolver) |
+| `10002/tcp` | 80 | Web admin (HTTP) |
+| `10003/tcp` | 443 | Web admin (HTTPS) |
+
+`docker-compose.yml`:
+```yaml
+services:
+  pihole:
+    container_name: pihole
+    image: pihole/pihole:latest
+    hostname: pihole
+    ports:
+      - "53:53/tcp"
+      - "53:53/udp"
+      - "10002:80/tcp"
+      - "10003:443/tcp"

+      FTLCONF_dns_listeningMode: 'all'
+    volumes:
+      - './etc-pihole:/etc/pihole'
+    cap_add:
+      - SYS_NICE
+    restart: always
+```
+- Upstream DNS (from copied `pihole.toml`): `192.168.3.16`, `8.8.8.8`, `2001:4860:4860::8888`.
+- Adlist: `https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts`.
+- `pihole.toml` `interface` was adapted from netboot's `eth0` to the target's `ens18`.
+- Web admin: `http://<node>:10002/admin/` — password **`Gransyan1!`** (same as netboot).
+- Web UI URL per node: `http://100.70.181.72:10002/admin/` (-01), `http://100.93.194.82:10002/admin/` (-02).
+
+## 4. Technitium DNS (container `tsys-dns`)
+
+Image `technitium/dns-server`; `restart: always`. Authoritative DNS for
+`knel.net` (and Tailscale reverse zones), config copied verbatim from netboot's
+orphaned `dns_tsys-dns-config` volume.
+
+| Host port | Container | Purpose |
+|---|---|---|
+| `5300/tcp`, `5300/udp` | 53 | DNS (remapped — see note) |
+| `5380/tcp` | 5380 | Web console (HTTP) |
+| `53443/tcp` | 53443 | Web console (HTTPS) |
+
+`docker-compose.yml`:
+```yaml
+services:
+  technitium:
+    image: technitium/dns-server
+    container_name: tsys-dns
+    ports:
+      - "5300:53/tcp"
+      - "5300:53/udp"
+      - "5380:5380/tcp"
+      - "53443:53443/tcp"
+    volumes:
+      - './config:/etc/dns'
+    restart: always
+```
+- Zones loaded (verified): `knel.net` SOA → `dns.knel.net. hostadmin.knel.net. 2025062313 900 300 604800 900`, plus 12 Tailscale reverse zones.
+- Web console: `http://<node>:5380/` → user **`admin`** + the original Technitium
+  password (carried over via `auth.config`). If the password is unknown, reset it
+  from the console or by removing `config/auth.config` and recreating the container.
+- **Port note:** Technitium's native DNS port (53) is remapped to host **5300**
+  because Pi-hole already owns host :53 (they cannot both bind 0.0.0.0:53). To
+  query the authoritative server: `dig -p 5300 @<node> knel.net SOA`. To make
+  Pi-hole resolve `knel.net` via Technitium, add a conditional/local upstream in
+  Pi-hole pointing to the container (e.g. `127.0.0.1#5300` is not host-reachable
+  from Pi-hole's netns — use the docker bridge IP of `tsys-dns`, or add
+  `knel.net` A-records directly in Pi-hole's Local DNS).
+
+## 5. NTP (host `ntpsec`, not a container)
+
+Both targets **already run a bare-metal `ntpsec` daemon** (active, enabled) that
+serves NTP on every local address — including the Tailscale IP — and keeps the
+system clock synced. This is the **same daemon family as netboot's own bare-metal
+ntpsec**.
+
+- **Why no chrony container?** netboot's chrony container (`tsys-ntp`) binds the
+  Tailscale IP `100.103.64.82:123`; on netboot that works only because its ntpsec
+  does **not** pre-bind the specific Tailscale-IP socket. On these targets ntpsec
+  **does** bind the Tailscale IP, so the container cannot claim it (`address
+  already in use`) and would be a non-functional duplicate (verified: the
+  container started but never synced — Stratum 0). It is therefore intentionally
+  **omitted**; host ntpsec provides NTP. `setup-netinfra.sh` detects an active
+  host NTP unit and removes any stale `tsys-ntp` container.
+- ntpsec config (`/etc/ntpsec/ntp.conf`): Debian NTP pool (`0-3.debian.pool.ntp.org`),
+  `restrict default kod nomodify noquery limited` (serves time, blocks mgmt queries).
+- Verified sync: -01 stratum 2 (~2 ms offset), -02 stratum 3 (~0.2 ms offset),
+  leap normal.
+
+The `ntp/docker-compose.yml` is still written on each node for parity/reference
+(and in case the host NTP is ever disabled — then `sudo docker compose -f
+/home/localuser/services/ntp/docker-compose.yml up -d` brings up chrony).
+
+## 6. Verification results (2026-07-28)
+
+| Check | pfv-netinfra-01 | pfv-netinfra-02 |
+|---|---|---|
+| `pihole` health | healthy | healthy |
+| `dig @127.0.0.1:53 pi.hole` | `172.18.0.2` | `172.18.0.2` |
+| Pi-hole web `:10002` | HTTP 302 (→login) | HTTP 302 |
+| `dig @127.0.0.1:5300 knel.net SOA` | SOA answered | SOA answered |
+| Technitium web `:5380` | HTTP 200 | HTTP 200 |
+| NTP daemon | ntpsec, stratum 2, synced | ntpsec, stratum 3, synced |
+
+## 7. Operating the services
+
+```bash
+# status
+sudo docker ps
+
+# Pi-hole
+sudo docker compose -f /home/localuser/services/pihole/docker-compose.yml ps
+sudo docker compose -f /home/localuser/services/pihole/docker-compose.yml logs -f
+sudo docker exec pihole pihole -v          # version
+sudo docker exec pihole pihole -g          # rebuild gravity
+sudo docker exec pihole pihole -a -p       # set/change web password
+
+# Technitium
+sudo docker compose -f /home/localuser/services/technitium/docker-compose.yml logs -f
+sudo docker exec tsys-dns sh               # explore /etc/dns
+
+# NTP (host)
+systemctl status ntpsec
+ntpq -pn
+```
+
+## 8. Differences from pfv-netboot (intentional)
+
+1. **Layout** under `/home/localuser/services/` instead of `/root` (so `localuser`
+   can manage compose files); Pi-hole data dir still owned by `localuser`, as on netboot.
+2. **Pi-hole `interface`** set to `ens18` (targets' NIC) instead of netboot's `eth0`.
+3. **NTP:** host `ntpsec` (Debian pool) used instead of netboot's chrony container
+   (the container cannot bind the Tailscale IP here; see §5).
+4. **Technitium DNS** host port remapped `53 → 5300` to avoid clashing with Pi-hole
+   on `:53`. The `knel.net` zone and all reverse zones are identical to netboot's.
+5. Pi-hole query logs (`pihole-FTL.db*`) and regenerable caches/backups are not
+   copied (transient); gravity DB and all configuration are.
+
+## 9. Re-running / reproducing
+
+`setup-netinfra.sh` is **idempotent** — it skips re-copying config if already
+present and uses `docker compose up -d` (no-ops when unchanged). It reads
+pfv-netboot read-only and never mutates it.
+
+```bash
+./setup-netinfra.sh                       # deploy to both nodes
+./setup-netinfra.sh pfv-netinfra-01       # deploy one node
+./setup-netinfra.sh pfv-netinfra-01 verify   # verify only
+```
+
+Prerequisites: SSH key access to all three hosts as `localuser` with passwordless
+sudo; the targets reach `192.168.3.16`/`8.8.8.8` for Pi-hole upstream and the
+internet for image pulls.
