An AI agent was allowed to pay a supplier yesterday. This morning the supplier's account was flagged for fraud. Nobody cancelled the permission. Should the payment go through? On sebbi.pro it doesn't. Every action is checked at the moment it happens against the facts its permission depends on, and if one has changed, the action is stopped and the refusal is sealed as evidence.
The Temporal Standing Test is a published protocol for whether a system really re-establishes authority at the moment an action takes effect. It's run here against the live engine, with the implementation frozen and sealed before every run, the four cases in random order, and every run listed, failures included.

| Case | Change at dN | Required at Tn | Result |
|---|---|---|---|
| A | revocation, standing-defeating | DENY / NON-EXECUTABLE | PASS |
| B | revocation, standing-preserving | PERMIT / EXECUTABLE | PASS |
| C | external fact, standing-defeating | DENY / NON-EXECUTABLE | PASS |
| D | external fact, standing-preserving | PERMIT / EXECUTABLE | PASS |
Run it yourself, now. The test runs on production and the result is sealed whatever it is. One run every 10 minutes.
The permission is cancelled after approval. The action must not happen.
A different, unrelated permission is cancelled. The action must still happen, exactly once.
The permission is untouched: not revoked, not expired, not altered. But the fact it depends on changes. The action must not happen.
Some other fact changes. The action must still happen, exactly once.
Attach the facts a permission depends on. They're checked at the moment every action binds, and they only ever narrow authority.
