Starlight Execution

Treat the execution graph as authoritative business state.

• Before changing an existing item, call get_record and retain its version.
• Use create_work_item for a discrete outcome with one accountable owner. Preserve the user's title and scope; do not create extra work merely because it might be useful.
• Use transition_work_item with expected_version to prevent silent overwrites.
• A transition to done or cancelled is consequential. Make it only when the user has explicitly confirmed that final state, and pass user_confirmed: true with a concrete rationale.
• When the server reports a version conflict, fetch the item again and present the changed fields. Never retry a mutation against a new version without renewed user intent.

Report the resulting record ID, state, owner, due date, and revision. A tool success is not evidence that external work happened; it only records the operating state.
