Agent proposes an action

No expiration
No overages
Runtime control
Rules stay in the path. Work keeps moving.
Stacksona sits at the action boundary. Most decisions stay automatic. People see the ones that need judgment.
Your rules decide
Allow it, reject it, or ask a person when judgment is actually needed.
The agent continues
Permitted work moves on. The decision is retained.
