What are you seeing?

The same registry, entered by symptom rather than by instrument. You usually know what it looks like before you know how you were fooled.

• The page renders blank Nothing visible, but the DOM may be complete and merely invisible. NS-010 NS-002 NS-004
• The deploy ran but nothing changed The new code is on disk. Something between disk and user is still serving the old one. NS-005 NS-007 NS-008 NS-026 NS-038
• The command succeeded but had no effect Exit zero describes the process, not the outcome you wanted. NS-005 NS-015 NS-016 NS-014
• The service says active but is not working Active is a statement about a process existing, not about it serving. NS-026 NS-027 NS-005 NS-037 NS-038
• An animation or counter never moves Frozen at frame zero is indistinguishable from correctly static. NS-001 NS-002
• The tests pass but the feature is broken A test that never ran, and a test that asserts nothing, both report green. NS-017 NS-018
• The API returned 200 but the data is wrong The status describes the transaction, not the payload. NS-020 NS-021 NS-019 NS-025 NS-042 NS-045
• My config change is being ignored The file records intent. Something later, or something else, decided the outcome. NS-003 NS-023 NS-008 NS-046
• The logs show nothing useful Silence is produced by a filter, a rotation and a crash alike. NS-029 NS-028 NS-011 NS-031 NS-032 NS-033 NS-034
• A process died and I cannot tell why The thing that was killed is often not the thing that caused it. NS-011 NS-013 NS-014 NS-031
• A URL returns 200 for something that does not exist A catch-all answered on the origin's behalf. NS-022 NS-007 NS-043
• Clicks land on nothing The element you can see is not the element receiving the event. NS-030
• The wrong file or image was used A plausible artifact of the right type is not evidence it is the right one. NS-006 NS-004 NS-048
• Text renders, but it looks wrong A substitution that still renders is invisible without a comparison. NS-004 NS-024
• Assets take seconds to appear Late departure and slow transfer feel identical from the viewport. NS-009
• Numbers come back subtly altered Silent coercion produces a valid value that is not your value. NS-025 NS-019 NS-046
• A search for a process finds something unexpected The instrument is a process, and it is inside its own sample. NS-012 NS-027 NS-036 NS-039 NS-040 NS-041
• A command hangs and never returns There is no exit code to read, and silence resembles progress. NS-014 NS-013
• Log lines are in an impossible order Two streams with different buffering do not interleave the way they were written. NS-035
• Credentials are ignored but the request still succeeds Something in the chain dropped the header and the endpoint answered anyway. NS-044
• A fresh clone is missing files that are present locally Committed is not the same as tracked. NS-047
