Lumbridge Compute
Governed compute for unified-memory AI hardware — the machines where CPU and
GPU share one pool and there is no separate VRAM allocation to bounce off.
Over-commit that pool and the box thrashes and wedges, SSH and ping included,
before the OOM killer gets a turn.

Compute does not run inference. It supervises the servers that do:

- Admission control. A model starts only if committed + requested + margin
  fits the budget. The refusal is the feature.
- A 1 Hz watchdog on MemAvailable that stops the newest model before thrash.
- Scenes: named sets of models activated as one transactional unit, with
  pre-flight validation and rollback to the previously active Scene on
  failure. Scenes reference model ids, never weight paths or commands, so a
  Scene obtained from elsewhere cannot introduce code.
- Process ownership bound to (boot_id, pid, start_time_ticks, pgid == pid),
  so a reused PID can never be group-killed.
- A protocol-transparent TCP gateway, so clients keep one address while model
  runtimes move behind it.
- An MCP server, so agents drive the node as tools rather than as a CLI.

One binary, six direct dependencies, no async runtime outside the MCP surface.

Published from the internal monorepo with a fresh history. The private
development tree keeps its own history; nothing here carries it.

# budget matches the empirically safe studio ceiling on the reference node while retaining
# Lumbridge Compute's separate 8 GB admission margin.
