DCGM is NVIDIA's own Data Center GPU Manager -- first-party, Apache-2.0, packaged as datacenter-gpu-manager -- and it layers above NVML rather than beside it: nvidia-smi is a thin CLI over NVML's per-GPU primitives, and DCGM is a daemon plus dcgmi adding health, diagnostics, config enforcement, policy and group abstractions on top. Which is why its group notion still resolves to N per-GPU writes underneath. The caveat that matters, and it undercuts the experiment suggested in the previous commit: DCGM is datacenter-oriented and parts of it are gated to datacenter SKUs of the Tesla/A100/H100 class. Our cards are professional/workstation parts -- RTX PRO 6000 Blackwell Max-Q and RTX 6000 Ada -- and several DCGM capabilities are unsupported or degraded outside that line, plausibly including config enforcement, which is precisely the power path. So DCGM_CONFIG_POWER_BUDGET_GROUP may return 'unsupported on this device'. Downgraded from 'worth testing' to five minutes of curiosity after the real work, and explicitly not a planning assumption. None of which touches the plan: nvidia-smi -pl 250 is plain NVML and works on these cards. DCGM would only have bought the group-budget experiment and nicer telemetry, and is probably not installed anyway since beszel-agent-nvidia shells out to nvidia-smi.

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/.
