The log tee wrote through to the real stream unguarded, and the worker pool tees a returned call's logs there after reading its result and before handing it back — so a dead stdout, which `fluksio serve` makes possible by running the engine as a child of the dashboard holding that pipe, failed the node with its outputs already in hand. The capture half runs first, so swallowing the write loses nothing. Also: `flow_events` catches the RuntimeError a peer leaving mid-send raises, which is a disconnect by another route, and the remote agent no longer raises out of the task when its subprocess died before it could be written to — the read below reports that and ends the call.

fluksio-worker
Runs Fluksio nodes on a machine the engine cannot reach — a GPU box, a cluster node, anything behind a NAT. It dials out to the engine over one authenticated websocket, so nothing has to be exposed here.
pip install fluksio-worker
fluksio-worker \
--url wss://api.example.com/api/v1/workers/attach \
--token "$FLUKSIO_WORKER_TOKEN" \
--labels gpu,cuda12 \
--python /opt/torch-venv/bin/python
--python is the interpreter node code runs on, which is how this machine keeps
its own wheels without the engine ever installing them. Mint a token from the
engine with POST /api/v1/workers/tokens.
