Direct answerIndependent read-back means checking the resulting state after an agent changes something, using an observation that is meaningfully separate from the action acknowledgement.
Why acknowledgements are weak proof
A successful API response, write receipt or click event usually proves only that the action was accepted. It does not always prove the desired final state.
Examples
- After writing a file, read and validate the file.
- After changing a setting, query the effective setting.
- After starting a service, check health.
- After a UI action, inspect the resulting interface state.
- After a device command, observe the relevant device state.
Independence matters
The verification path should not merely repeat the same assumption that produced the action acknowledgement. The stronger the consequence, the more valuable an independent observation becomes.
What to publish
Publishing the principle and scoped test outcome is usually enough. A commercial system does not need to disclose its private verification state machine or trust contract to demonstrate engineering discipline.
