Operator's reasoning, accepted and better than the hypothesis-space argument it replaces: the NAT change went effective, was verified bidirectional, and then ran correctly for twenty minutes before the site died the moment GPU load was applied. A working config change does not spontaneously fail under an unrelated physical variable. The load correlation is tight; the NAT correlation is merely adjacent in time. Undersized UPS is the only candidate that explains the trigger. NAT material retained as record, and the power.log/uptime check demoted from decision point to free confirmation. Adds the measurement protocol, since the operator is bringing a PDU and an ammeter. The load-bearing caveat: power.log is GPU-ONLY -- nvidia-smi per-card, excluding CPU, 566 GB of RAM, drives, fans and PSU conversion losses -- so the ammeter at the plug is the primary instrument and power.log only cross-checks the GPU share. Four states to capture (idle, one card, two cards, four cards), and capture PEAK rather than average: UPS overload protection responds to short-term overload, so an average-only reading that hides transients will mis-size the replacement exactly the way the present unit got mis-sized, and must be recorded as a floor rather than as the draw. The four-card figure is earmarked for servers/fv-ml1/README.md, because it closes the cutover's own open question -- that the FV circuit was likely specced against half the real draw, back when every record still said the box had two GPUs.

Navigation map for the documentation tree. New session? Read
orientation.md first — it's the narrative overview
of the fleet, backup architecture, governing principles, and gotchas,
and it points at everything else.

What goes where
runbooks/— step-by-step ops procedures. Anything you'd reach for during an incident or while standing up new infrastructure. Examples: disaster recovery (blast-radius tiers + restoration steps), PBS deployment (9-phase rollout). New runbook → new file here.pfi/— PFI-specific reference material that's too narrow for the top-level CLAUDE.md but doesn't change incident response. AI model inventory, recommended inference settings, Matrix bridge config, Proxmox VM map. New stable reference → new file here.- Top-level (
docs/orientation.md,docs/README.md) — narrative guides about the workspace itself, not about specific infra.

Conventions
- Markdown, GitHub-flavored. CommonMark renders fine in most viewers.
- File names are lowercase-kebab-case, descriptive. No dates in filenames — git history covers that.
- One topic per file. If a file grows past ~500 lines, look for a natural split before adding more.
- No checked-in binaries or checksums. Build/release artifacts belong
in a build pipeline or
tools/, notdocs/.
