Failure forensics: method
20,000 leads. 40 equipment classes x 25 degradation paths x 20 diagnostic signals. The question is never "what failed" but "which degradation path is consistent with the signals that were kept". None tested except the
items on the results page.
The composition is balanced: every domain meets every degradation path and every signal, so the catalogue
is a complete grid rather than a ranked list. That is deliberate — for forensics and recovery the useful
move is often to notice a combination nobody tries, which a ranked list hides.

4. How to use it
- Find your domain and the signal you already have.
- Read across the row: every mechanism consistent with that signal is listed.
- Ask which one your current test cannot exclude. That is the lead.
5. Limits
- Balanced and therefore unfiltered; the grid contains nonsense by construction.
- No prior-art check; several rows are standard practice.
- Only the results page has numbers.
