Check independently supplied outcomes at 299, 300 and 301 seconds, plus a withdrawn observation. These cases use producer metadata retained before this lesson.

## Check original-time boundaries

1. **Read the independent expected outcomes**

   Read the independent expected outcomes

   The expected outcomes were supplied before running the rule. Check them against the requirement.

2. **Inspect the first observation**

   Inspect the first observation

   Read the original observation, captured source state and expected result together.

3. **Check the metadata identity**

   Check the metadata identity

   Calculate only the identity of the entered metadata. It does not prove authenticity or fill in any expected result.

4. **Retain the complete expected cases**

   Retain the complete expected cases

   Save the complete set without copying computed results into expected outcomes.

5. **Read the retained case set**

   Read the retained case set

   Reload the original saved cases before asking for verification.

6. **Verify the saved cases**

   Verify the saved cases

   Run the deterministic definition against the independently entered outcomes.

7. **Read the passing proof**

   Read the passing proof

   Read the retained proof. At exactly 300 seconds the original observation is eligible; at 301 seconds it is too old.

A passing check supports review. It does not approve the definition, admit an unqualified source or publish a Data configuration.
