ARG-003
Hard constraint
layer: paragraph
Classify claim before selecting evidence
IF a claim is present, THEN classify it as factual, causal, evaluative, definitional, predictive, or policy before choosing support ELSE do not infer support requirements.
Why the rule exists
Different claims require different evidence and warrants.
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.
- paragraph.claim exists
Facts this rule reads
| Path | Source |
|---|---|
paragraph.claim |
You supply it |
Then
- classify — target
paragraph.claim
Else
- retain — target
current_text, No triggering condition is present.
LAKA
- Smallest sufficient intervention
- Yes
