Field note
Logging existed; observability did not
A logging setting and access records did not establish that the important production behaviors were observable.
How the claim changed
Belief
If logging is enabled and integration tests show access logs, production behavior should be observable enough to diagnose failures.
Evidence
Durable logging existed and test environments emitted the expected access records.
Contradiction
Production evidence showed that an embedded metrics server could reset process-wide logging configuration. A later seam audit found important behaviors remained weakly observed.
Correction
Treat observability as coverage of the behavior being investigated, not as a boolean logging setting. Instrument the actual failure seams and verify them under production-like conditions.
Current claim boundary
“Logging is enabled” is not evidence that the relevant behavior is observable.
Public evidence
No direct public artifact supports the earlier logging-reset finding, so this curated note does not fabricate an evidence link.
