ETH-001
Hard constraint
layer: sentence
No known false statement
IF a statement is known to be false, THEN correct or remove it ELSE continue to evidence review.
Why the rule exists
Truth is a non-negotiable constraint, not a style preference.
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.
- claim.known_false eq true
Facts this rule reads
| Path | Source |
|---|---|
claim.known_false |
You supply it |
Then
- block_publication — target
claim - correct_or_remove — target
claim
Else
- retain — target
current_text, No triggering condition is present.
