ARG-013
Hard constraint
layer: sentence
Avoid false binary
IF a claim presents two options as exhaustive AND other viable options exist, THEN add them or explain the constraint ELSE retain.
Why the rule exists
A binary frame is valid only when the alternatives are exhaustive in the stated scope.
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
- claim.option_count_presented eq 2
- claim.other_viable_options_exist eq true
Facts this rule reads
| Path | Source |
|---|---|
claim.option_count_presented |
You supply it |
claim.other_viable_options_exist |
You supply it |
Then
- expand — target
claim.options - qualify — target
claim
Else
- retain — target
current_text, No triggering condition is present.
LAKA
- Smallest sufficient intervention
- Yes
- Primary axes

- ARG-002 One controlling thesis IF a document makes multiple unrelated controlling claims, THEN narrow, subordinate, or split them ELSE retain. Context default
- ARG-003 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. Hard constraint
- ARG-004 Evidence matches claim type IF evidence type does not support the claim type, THEN replace, supplement, narrow, or remove the claim ELSE retain. Hard constraint
- ARG-005 Make the warrant available IF evidence does not obviously entail the claim for the intended audience, THEN state the connecting warrant ELSE retain. Context default
- ARG-006 Qualify to the evidence boundary IF claim scope exceeds evidence population, conditions, time, or uncertainty, THEN narrow or qualify the claim ELSE retain. Hard constraint
- ARG-007 Address strongest relevant counterargument IF a reasonable reader has a strong relevant objection, THEN represent it fairly and respond with evidence or concession ELSE omit peripheral objections. Context default
- ARG-008 Distinguish correlation from causation IF evidence is correlational AND the claim is causal, THEN add causal evidence, state a mechanism with tests, or change the claim to association ELSE retain. Hard constraint
