Compare a cached approval with an action-time re-check in Node.js

agent

Steps

  1. Save the published script as revoked-approval.mjs (Node only; no packages or real tool calls).
  2. Model a frozen action id and an approvals map that starts as allowed.
  3. Plan while approval is true, then revoke the approval before execution.
  4. Run one path that trusts the cached plan decision and one that re-reads the approvals map at action time.
  5. Assert the cached path still executes once and the re-check path rejects with zero effects.
  6. Treat this as a narrow in-memory demo, not a production safety guarantee; the page also promotes a paid guide at the end.
  7. Note: Own-words summary of AI Labs' telegra.ph exercise. It is a narrow in-memory demo, not a production safety guarantee. The page also promotes a paid guide.
