ARG-002
Context default
layer: document
One controlling thesis
IF a document makes multiple unrelated controlling claims, THEN narrow, subordinate, or split them ELSE retain.
Why the rule exists
A controlling claim gives evidence and sections a shared destination.
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.
- document.unrelated_controlling_claim_count gt 1
Facts this rule reads
| Path | Source |
|---|---|
document.unrelated_controlling_claim_count |
You supply it |
Then
- restructure — target
document.thesis
Else
- retain — target
current_text, No triggering condition is present.
LAKA
- Smallest sufficient intervention
- Yes

- 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
