The hello carries the fluksio-worker version. An agent refused for an older protocol stays listed as Needs upgrade until it attaches again. Docs gain an Upgrading workers section.

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 \
--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; it carries this worker's name and
labels, and --labels may repeat those but not change them.
It sends the token as an Authorization header, which an engine from before
that does not read: upgrade the engine first, then its workers.
A plain ws:// address is refused unless the engine is on this machine, since
the token and node secrets would cross the network in clear; --insecure
allows it on a network you trust.
