UCS (LDAP/AD) does not need SSD. Corrected placement:
- ucs-01 stays on D2 (tsys4 HDD) -- no change needed
- ucs-02 moves from D5 (tsys4) to S2 (tsys5 HDD) for cross-server
redundancy only, not for speed
D3 SSD (moving to tsys5 Friday) is now freed for workloads that
actually benefit: sectestbed k8s nodes, CI/CD artifact cache, or a
container image registry mirror.
Added storage tier characterization per host (tsys4 = bulk/spinning
only, tsys5 = hybrid fast-tier hub, tsys2/3 = SSD/NVMe only). Added
UCS migration TODO item for today.

Verified via lsblk TRAN column and dmesg that tsys6/7 local-lvm is
backed by WD My Passport portable HDDs on USB 2.0 (~30 MB/s), not
internal SATA/SAS as previously assumed. Both R610 and R620 only have
EHCI controllers -- no USB 3.0/xHCI. tsys7 has 5 empty SATA ports but
no drives installed; tsys6's SAS controller is disabled in BIOS.
Corrected all wnode recommendations: tsys6/7 stay on NFS (faster than
their USB 2.0 local-lvm). Only tsys3/5/9/2 have local storage suitable
for VM boot disks.
Also discovered tsys3 boots from Samsung PM961 NVMe 512GB (previously
documented as HDD). Its 349 GB local-lvm is the fastest existing local
storage in the fleet.
Updated speed tier table, wnode placement tables, storage distribution
matrices, migration plan, and caching strategy across PROJECT.md and
K8S.md.

tsys2 validated via PowerShell on Windows: 2 SSDs (Samsung 960 PRO
NVMe 512GB + Samsung 850 EVO SATA 1TB) -- the best local storage in
the fleet. wnode-tsys2 needs no NFS; boot on NVMe, bulk data on SATA
SSD. Both NICs are USB dongles (ASIX + Realtek) -- unavoidable on
this laptop form factor, no PCIe NIC expansion possible.
Updated storage tiers, wnode placement, and k8s labeling to reflect
that tsys2 is the fastest-storage worker node. Marked TODO.md items
as resolved.

Adds the PowerShell and cmd.exe commands the user needs to run on the
Windows host (pfv-tsys2) to gather disk, network, RAM, GPU, and PCIe
details before rebuilding it as Proxmox. Also documents the Friday
maintenance window steps (tsys4 NIC+RAM, tsys5 cable+NVMe) and open
questions for the next session.

Add __pycache__/*.pyc to .gitignore and remove the tracked bytecode
file. Add version control instructions to AGENTS.md for future sessions.
