ducoterra b389bb4a94 Wire the live-test gate and pin the toolchain to 3.14
README advertised `uv run pytest -m live --live`, but there was no --live
option and no `live` marker registered — the command errored out, so the
one workflow that catches an upstream renaming a series did not exist.

- conftest adds --live and skips `live`-marked tests without it, so the
  default run stays hermetic (258 passed, 6 skipped, no network).
- tests/test_live_fleet.py drives the real code paths (collectors.*,
  NutMonitor.collect) against the fleet, both engines, and upsd. Each
  skips when its source is unset, and none of them may write — a battery
  test on live hardware is not a unit test. The host test polls twice
  because a rate has no second point on the first scrape.
- The agent's real-/proc test stays in the default run and is explicitly
  not `live`: it touches only the box running pytest.
- dev-tunnels.sh grows DEV_FORWARDS for services already listening
  remotely, which is how upsd gets reachable without opening 3493;
  pidfiles are now host+port so one host can carry two tunnels.
- requires-python, ruff and pyright were still on 3.13 while the venv and
  Containerfile are 3.14, so the lock resolved for a stack nobody deploys.

ducoterra 87042f8855 Add AGENTS.md and align the docs with the code
The brief asked for an AGENTS.md capturing the overall plan and it never
landed, while two files already pointed readers at it. It now holds the
invariants (read-only by construction, never invent a number,
unconfigured is not broken, no CDN, no guessed metric names), the locked
decisions with their reasons, the verified fleet facts, the commands, and
the four known gaps.

Also corrected the docs that had drifted:
- upsd config lives in /etc/ups on driveripper, not /etc/nut, and the
  real blocker is that upsd binds nothing on 3493 — with the sudo rules
  still needed written down in deploy/nut-sudoers.
- .env.example told operators to set `LISTEN 0.0.0.0` and `actions = -`;
  both are worse than needed. Loopback + ssh forward, and per-command
  instcmds instead of granting load.off.
- nut.py claimed the command path is gated three times and that the
  confirmation asks for the UPS name; it is gated four times and asks
  for DANGER.
- .gitignore described a tracked .agents/ roadmap that does not exist.

ducoterra 426682a999 Add the deployment path: agent systemd unit and container image
The README referenced `deploy/install-agent.sh` and a `Containerfile` that
did not exist, so a fresh clone had no way to actually run this anywhere.

* agent: `--token-file` (and AGENT_TOKEN_FILE). The token guards hostname,
  mounts, disk and GPU models and process names, and argv is world-readable
  through `ps`, so a file has to win over the flag. Missing or empty token
  files are fatal — falling back to "no token" would expose the host.
* deploy/install-agent.sh: creates a system user, generates the token once
  (re-runs reuse it, --rotate-token for a new one), stores it 0600
  root-owned, and runs the agent under ProtectSystem=strict with no
  capabilities; --status and --uninstall included.
* Containerfile: two-stage, uv.lock resolved in the builder and slim Python
  in the runtime. Verified with podman — the image serves /api/health as an
  unprivileged user and writes its history under /var/lib/dashboards.
  UV_PROJECT_ENVIRONMENT and --no-editable are what make the venv survive
  being copied into the runtime stage.
* .containerignore keeps .git, .venv, data/ and .env out of the build
  context.

258 tests, 94% coverage; ruff and pyright clean.

ducoterra c4bb374ccc Add homelab dashboards: system, LLM, and UPS on one domain
Three dashboards served by one FastAPI app with a SQLite history store
(raw / 1m / 1h) and hand-written SVG charts: no Prometheus, no Grafana,
no CDN, no build step. Nothing is fetched from the internet at runtime.

* system: a stdlib-only agent (agent/host_agent.py) reports /proc and
  /sys counters; the dashboard turns them into rates over a labelled
  window, so every number says how it was measured.
* llm: gufo/llama.cpp and vLLM /metrics are parsed by an in-house
  exposition parser. Measured delta/elapsed throughput beats a native
  per-request gauge, and each value carries its provenance.
* ups: a NUT wire-protocol client plus health checks that name what
  they looked at. Commands are gated by NUT_ALLOW_ACTIONS,
  DASH_READ_ONLY and a DANGER confirmation, re-checked server-side.

Missing values render as n/a rather than 0, and an unconfigured source
answers 404 {"configured": false} without dialling anything, so "not
deployed here" never looks like an outage.

253 tests at 94% coverage against captured real fixtures; ruff and
pyright clean.
