SYSE.43:5.3 - Preserve an earlier observation without treating it as current

An agent resumes a test-service change after interruption. Its memory contains “meter-2 used interval 10 seconds at revision 82” and a trace link. A later authoritative observation says revision 83 uses 2 seconds.

The task is to explain current sampling, so the query includes meter-2 and current configuration. The record at 82 remains evidence of the earlier change, but the answer consumes the observation at 83. A summary saying “meter-2’s interval is 10 seconds” would lose the time condition and is repaired. Its dependent retrieval entry is updated.

In a diagnostic task, the earlier 10-second episode may still matter: it explains when the behavior changed. The same stored record therefore remains useful without being promoted to a current fact.

Now suppose the correct revision-83 record is returned but the final report still says 10 seconds. Enlarging the index does not repair that failure. Inspect the actual next input through SYSE.52 and the step that consumes it through SYSE.47. Restore a field lost during assembly in the former; repair an ignored return in the latter. If revision 83 was never captured, repair writing or access instead.
