mrcharles 8124483da8 feat(powerman): manage Cyclades PM10i PDU via powerman on pfv-tsys1 
Set up centralized PDU management for a Cyclades AlterPath PM10i (10
controllable AC outlets) connected to pfv-tsys1 via a Prolific USB-to-DB9
serial adapter. powermand is now listening on 0.0.0.0:10101, making the
PDU manageable over the network from any host on the tailnet.

Scripts (powerman/):
- discover.sh: gather USB adapter, powerman state, device definitions
- setup.sh: idempotent setup — udev rule (stable symlink by serial number),
  powerman.conf with 10 outlet nodes, fix powermand dialout group, restart
  service. Overridable via env vars for other hosts/PDU types
- test-pdu.sh: validate control by cycling outlet 10 off then on (8/8 pass)
- status.sh: quick PDU status check

Issues fixed during setup:
- Config pointed at /dev/ttyUSB0 but adapter is at /dev/ttyUSB1 (fixed
  with udev symlink /dev/cyclades-pm10 pinned to adapter serial)
- powermand (user:powerman) lacked dialout group membership to open the
  serial device (fixed with usermod + udev GROUP="dialout")

Validation: outlet 10 turned off (confirmed), turned on (confirmed), then
cycled. All 10 outlets currently ON and manageable.

TODO tracked for Friday: rename outlets from generic (outlet-1..10) to
match physical devices, and change PDU admin password from factory default.

## 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 `0.0.0.0:10101` (network-accessible)
- [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)
### 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
## Known Issues
| Issue | Impact | Status |
|-------|--------|--------|
| Technitium AXFR uses port 53 (occupied by Pi-hole) | Zone transfer via rsync instead of native AXFR | Workaround in place |
| `download.proxmox.com` unreachable from sandbox VM | 2 validation tests warn (environmental) | Not a code issue |
| tsys4/5 hardware pending | Perf tuning incomplete on 2 hosts | Waiting on physical install |
## Pending (next session priorities)
1. **PDU: rename outlets** in `/etc/powerman/powerman.conf` to match physical
devices (Friday onsite)
2. **k8s workers:** Join wnodes to the k3s cluster (agents, not servers)
2. **k8s: confirm 3 decisions** for future Talos/ITAR cluster:
- Cnode count: 3 (recommended) vs 5
- Cnode host spread: tsys9 + tsys1 + tsys3 (recommended, 3-host, local-lvm)
- Tailscale pattern: subnet router on `tailscale-router` (recommended)
3. Provisioning: add `tailscale up --accept-dns=false` after resolv.conf deploy
4. DNS: verify Pi-hole forwards knel.net to local Technitium on both nodes
5. Perf: complete tsys4/5 tuning after hardware install (Friday)
6. tsys2: rebuild from Win10 to Proxmox (k8s-dedicated host)
7. **k8s deferred topics** (tracked for future sessions): ETL tooling
(GDAL/PostGIS/xarray/Dask → RWX vs RWO), HPC scheduler (Argo/Volcano),
per-tenant vcluster policy templates, solar-aware scale-out
## Infrastructure Summary
