Errors and recovery
The error and recovery reference defines the externally observable state and next action required to resume an agent-operated broadcast safely.
Result contract
A result identifies the durable product context it observed or changed, the current outcome, material blockers, who can resolve them, and whether retrying the same mutation is safe. It does not ask the agent to infer state from an HTTP failure or a prior chat transcript.
Uncertain effects
When Fonte cannot establish a mutation outcome, its result preserves that uncertainty and directs the agent to the authoritative readback. The readback reconciles existing broadcast, import, test, or control state before any new mutation is considered.
