Sources stay attached
Compatibility and settings are stored as relations with source IDs and verification dates—not detached facts.
Trust methodology
Useful answers need visible evidence.
Every factual tool result is resolved from published records, retains its source, and can return an honest unknown.
Exact beats generic
Exact product and equipment records take priority over product-family or material-level fallbacks.
Conflicts stay visible
Equal-confidence settings are never averaged. Both sources remain visible with a conflict label.
Unknown is valid
When published evidence does not cover a combination, the result explains the gap without implying compatibility.
Compatibility order
Safety and specificity decide the match.
- Explicit incompatibility
- Exact manufacturer verified
- Exact third-party supported
- Family verified
- Conditional conversion rule
- Unknown
Correction policy
Known-bad advice is disabled first.
If a source or relation is found to be wrong, it is removed from published results so the tool returns unknown while the record is investigated.
