"""Capture a real signed proposal submission, for the CMS's cross-language test.

Same purpose as emit_upload.py, for the endpoint that matters now: testing each
side against its own fake proves only that a language agrees with itself. This
emits exactly what the real CmsClient puts on the wire so the CMS can replay
those bytes.

    python scripts/emit_proposal.py

Copy the output to the CMS repo at:

    tests/Feature/Agent/fixtures/python_proposal_request.json

Regenerate whenever the signing scheme or the proposal payload changes — a stale
fixture keeps passing against a contract neither side implements any more.

Nothing here contacts a network: urlopen is replaced before any call is made.
