Venice seats can be the worker: TIME_WORKER=venice:<seat>

A seat gets hands through the repo's own Actions token: list/read/write files on
branch time/card-N via the contents API, run shell on a checkout, open the PR.
Same contract as the Cursor worker (PR body says Closes #N), so review, landing
and next-card are unchanged. Workflow files are refused to the seat. Needs only
VENICE_API_KEY; no Cursor key.
