`pip install fluksio && fluksio serve` on a machine with no Docker, no database and no configuration — which is the case this is for: a node on a cluster where ports cannot be opened. It makes its data directory, its key and an admin account, prints the password once, and serves. Pairing is `fluksio enroll <code> --portal …`, doing what the Settings screen does through the same function, before the engine starts and without one running — a machine nobody can route to has no browser pointed at it either. The portal serves the dashboard, so nothing is served here. Two things had to give way. `fastapi[standard]` pulls a cloud CLI that wants sentry-sdk 2.x while we pinned below it — no pip resolution existed, so the pin is lifted, which the comment beside it had been waiting for and which also lets the Python cap go. And `uv` is now a dependency rather than something to find on PATH: the Modules screen is how a data scientist installs torch, and it was quietly falling back to the engine's own interpreter. The CLI imports nothing from the engine before it has set DATA_DIR — the settings are built on the first import of core.config, and reaching it early put the database in the working directory. There is a test for that now, because the failure is silent. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

"""The Fluksio engine.
|
|
|
|
Inside a node, ``import fluksio`` is not this package: the worker installs a
|
|
reporter of its own under that name before any node code runs, so what a node
|
|
gets is :mod:`fluksio_worker.worker_main`'s ``emit`` and ``save_artifact``.
|
|
The stubs below stand in the same place everywhere else, and say so rather
|
|
than failing as a missing attribute.
|
|
|
|
Nothing is imported from the rest of the package here. Every ``from fluksio.x
|
|
import y`` in the engine passes through this module, and an import cycle or a
|
|
second of start-up cost would both begin here.
