ARG-004
Hard constraint
layer: paragraph
Evidence matches claim type
IF evidence type does not support the claim type, THEN replace, supplement, narrow, or remove the claim ELSE retain.
Why the rule exists
An anecdote, measurement, authority, mechanism, and comparison answer different questions.
Condition
The rule fires when this evaluates true. Paths marked below must be present in the fact base; the engine reports the rest rather than guessing them.
- ALL
- paragraph.claim.type exists
- paragraph.evidence.compatible_with_claim_type eq false
Facts this rule reads
| Path | Source |
|---|---|
paragraph.claim.type |
You supply it |
paragraph.evidence.compatible_with_claim_type |
You supply it |
Then
- repair — target
paragraph
Else
- retain — target
current_text, No triggering condition is present.
