"""Turn a locally validated JobSpec into the payload sent to the control plane.

The one piece of client-local state a run needs is the pip requirements for installed
verifiers / Prime Hub environments (recorded in ``~/.flash/envs.json`` by
``slm env install``). The server has no access to that manifest, so the client resolves
it here and ships it inside the spec (``environment.pip``); a value already present in
the config (the documented escape hatch) wins.
