Question 1

Can an AI agent's action be undone?

Accepted Answer

Only partly, and only for a while. A compensating entry can reverse a record — a status change, an allocation, a database write. It cannot reverse a consequence: burned compute, a delivered email, a disclosed secret, or a model trained on the wrong data. The EcoCloud reversibility kernel measures, before the action runs, the recoverable share, the residue a reversal leaves behind, and how long the undo window stays open.

Question 2

What is the undo horizon?

Accepted Answer

The undo horizon is how long an action stays reversible. Because reversibility is time-dependent, the kernel computes the soonest window to shut among the effects that still have something to recover. If that horizon is shorter than the time your review takes, an approval that arrives afterwards cannot change the outcome — the kernel flags this as review theatre.

Question 3

Does EcoCloud hold funds or post a bond to cover irreversible actions?

Accepted Answer

No. The kernel measures and signs the reversibility of an action; it posts no bond, holds no collateral, slashes nothing, and prices nothing. Sunk resources are reported in the unit you state — GPU-hours, tokens, USD — and totalled per unit, never converted, because EcoCloud has no market data and does not invent an exchange rate. It answers what is unrecoverable, never who pays for it.

Question 4

What happens when an effect is unrecognised?

Accepted Answer

It is treated as irreversible. The kernel is fail-closed in the pre-execution direction: an unrecognised effect kind is irreversible, a missing undo window is treated as already shut, a delete is terminal unless a restorable backup is positively declared, and an action with no declared effects is undetermined and requires pre-approval. Reversibility is only ever granted on a positively-stated fact.
