Lumbridge Compute

Governed compute for unified-memory AI hardware — 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 against both a declared budget and what the machine actually has free,
a 1 Hz watchdog that stops the newest model before thrash, Scenes activated as
one transactional unit with rollback, process ownership bound to
(boot_id, pid, start_time_ticks, pgid) so a reused PID can never be
group-killed, a protocol-transparent gateway, an MCP server, and a read-only
HTTP API for dashboards.

Registry footprints in this release are measured on a live node rather than
estimated.

One binary, six direct dependencies. Apache-2.0.

Generated by scripts/publish-compute.sh, which refuses to publish a tree it
cannot prove clean.
