Docs moved from docs/k8s -> k8s/docs and docs/proxmox -> proxmox/docs to sit
beside their code. Updated all cross-references (docmap, STATUS, README, AGENTS,
k8s README). Fixed SCRIPT_DIR path resolution in 3 perf scripts broken by the
reorg (deploy-check/and-fix/finish-host pointed at root/scripts instead of
perf/scripts). Registered the new top-level proxmox/ dir in all listings.

Fresh Proxmox fleet audit (2026-07-28) with current VM placements, RAM,
CPU, and storage for all 7 reachable hosts. Written to
docs/proxmox/AUDIT-2026-07-28.md — supersedes placement data in
PROJECT.md sections 4-8.
Key audit findings:
- CRITICAL: UCS01/02 and netinfra01/02 HA pairs both still on tsys4
storage. tsys4 failure = DNS/DHCP/NTP + LDAP/AD fully dark. These
migrations were the #1 recommendation from the previous audit and
have not been done.
- CRITICAL: 2 of 3 active k3s cnodes (cnode1 + cnode2) on tsys4 NFS.
tsys4 failure = etcd quorum lost.
- 59% of running VMs still on tsys4 storage (improved from 68%).
- cnode VMIDs have changed since PROJECT.md was written (cnode1 is now
VMID 906 on tsys9, cnode2 is VMID 705 on tsys7, etc.)
Gardening fixes:
- Removed duplicate fleet-audit.sh (check.sh + deploy-check.sh already
exist for this purpose)
- Fixed hardcoded path /home/reachableceo/projects/perfopt in 13 perf/
scripts to use BASH_SOURCE-derived relative paths (per AGENTS.md
self-locating scripts convention)
- Updated STATUS.md Known Issues with the two critical findings
- Updated STATUS.md Pending with prioritized pre-k8s action items
- Registered AUDIT-2026-07-28.md in docmap.md

Solve the long-standing USB adapter enumeration shift problem: 9 Prolific
USB-to-DB9 adapters on pfv-tsys4 have no unique serial numbers and get
assigned /dev/ttyUSB0-8 based on enumeration order, which changes on every
reboot and breaks the old /root/conmap + manual screen workflow.
Solution: 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/<name>. ser2net opens
these stable symlinks and exposes them on TCP ports (2001-2007) bound to
the Tailscale interface only. conman connects to those TCP ports for
session logging and multi-user console sharing.
Architecture (layered, no port sharing):
USB adapter → udev symlink → ser2net (TCP) → conman (logging + mux)
Port assignments (all on Tailscale IP 100.70.77.93):
2001 = pfv-core-sw01 2002 = pfv-tor3-mgmt 2003 = pfv-tor3-stor
2004 = pfv-rrinfra-rtr 2005 = pfv-r2-tor-top 2006 = subodev-torsw
2007 = pfv-r2-sw
Scripts (console/):
- mapping.txt: source of truth (TCP port | name | ID_PATH | baud | comment)
- generate-config.sh: generates udev rules, ser2net.yaml, conman.conf
entries from mapping.txt. Idempotent (markers in conman.conf for clean
regeneration). Uses | delimiter (ID_PATH values contain colons).
- setup.sh: full deploy — generate configs, create symlinks (udev trigger
+ manual fallback for already-discovered devices), create conmand
systemd unit (Debian doesn't ship one), restart services
- discover.sh: read-only USB adapter and service state discovery
- validate-conman.sh: verify conman→ser2net→device data path and log capture
Issues fixed during development:
- /dev/console is a kernel char device (major 5, minor 1) — cannot create
a directory there. Changed symlink namespace to /dev/consoles/.
- conman 0.3.x has no 'include' directive — CONSOLE entries written
directly into /etc/conman.conf between idempotent markers.
- Debian conman package has no systemd unit — created
/etc/systemd/system/conmand.service with After=ser2net ordering.
- conman.conf had no LOGDIR — logs weren't being written to
/var/log/conman/. Fixed by adding server logdir directive.
Validation: 7 symlinks resolving, 7 TCP ports on Tailscale, conmand with
7 consoles registered, 7 log files actively capturing console output,
both services enabled for reboot survival.

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.

Bootstrap a regular (non-ITAR) k3s cluster on cnode1/2/3 with embedded
etcd. All cluster communication — node registration, API server, etcd
peering, flannel VXLAN — runs exclusively over Tailscale IPs. Zero LAN
addresses appear in node status or TLS certificates.
Scripts (k8s/):
- env.sh: shared config (Tailscale IPs, SSH opts, k3s version)
- wipe.sh: remove existing k3s from all cnodes
- install-cp.sh: full bootstrap (cnode1 --cluster-init, then cnode2/3 join)
- join-servers.sh: re-join cnode2/3 only (fixes broken join state)
- post-setup.sh: apply NoSchedule taints, fetch kubeconfig, verify
- verify.sh: 13-point health check (nodes, Tailscale IPs, taints, etcd,
CoreDNS, API server, workload isolation)
- probe-nodes.sh: SSH + Tailscale reachability check
All 3 cnodes are tainted control-plane:NoSchedule so no user workloads
can schedule on the control plane. 13/13 health checks pass.
Docs updated: k8s README TL;DR reflects k3s (not Talos) as the deployed
choice, with Talos preserved for the future ITAR cluster.

Author the docs/k8s/ directory capturing the pfv-k8s control-plane design:
- README.md: TL;DR of all decisions (distro, runtime, cnode count, admin
access, identity, tenancy, registry, storage)
- DISTRO-DECISION.md: Talos vs k3s analysis. Recommend Talos because the
ITAR/classified requirement makes its immutable, API-only, measured-boot
posture structurally easier to certify than SCAP-hardened Debian. k3s was
only ever a plan (no cluster deployed), so cutover cost is ~zero.
- ARCHITECTURE.md: target arch with mermaid diagrams covering control
plane, LAN-only network with Tailscale subnet-router admin, Cilium CNI,
OIDC to Keycloak, per-tenant vcluster isolation (incl. ITAR tenant),
Harbor pull-through cache on D3 SSD, bootstrap sequence, and DR.
Gardening: register docs/k8s/ in docmap.md, update STATUS.md with the new
k8s section and the three pending user decisions (cnode count, host spread,
Tailscale pattern).

Restructure top-level to exactly three .md files:
- AGENTS.md (agent operating instructions)
- README.md (project overview, links to status + docmap)
- STATUS.md (living project status, agent-maintained, human read-only)
Add docs/docmap.md as the single documentation index/map. All docs are
categorized (active, operational guides, historical) with last-reviewed
dates. Includes the agent gardening protocol requiring agents to update
STATUS.md and docmap.md after every work session.
Rewrite AGENTS.md to be lean: points to docmap.md for doc discovery,
encodes the automatic gardening protocol (keep docs/code in sync, grep
for stale paths after renames, update STATUS.md after infrastructure
changes). All references are Gitea-renderable relative links.
Simplify README.md: header links to STATUS.md + docmap.md + AGENTS.md,
doc table replaced with pointer to docmap.md.
