Read inapplicability separately from truth

Intent

I want to read inapplicability separately from truth.

Correct formFrozen execution sceneBoundary

Wrong form and why it stays silent

NOT_APPLICABLE is not part of truth_status. In why_not, applicability belongs to the candidate, not automatically to the root answer.

Incorrect form

expect truth_status == NOT_APPLICABLE;

Correct form

Arxo Law

language "law.core" version "0.2";
package recipe.m09 version "1.0.0";
namespace "urn:recipe:m-queries:09";
entity Person;
relation eligible(p: Person);
relation accepted(p: Person);
rule Accept strict { for p: Person; effective [@2026-09-01, @2026-10-01); when eligible(p); then accepted(p); }

Frozen execution scene

Input / variant	Question	Expectation
1. outside the window	truth(accepted(entity_ref("urn:recipe:m-queries:p")))	truth_status == NEITHER; evaluation_status == COMPUTED;
2. explanation outside the window	why_not(accepted(entity_ref("urn:recipe:m-queries:p")))	evaluation_status == COMPUTED; blocked_by(Accept);
3. applicable, but the body refuted	why_not(accepted(entity_ref("urn:recipe:m-queries:p")))	evaluation_status == COMPUTED; blocked_by(Accept);
4. applicable and fired	truth(accepted(entity_ref("urn:recipe:m-queries:p")))	truth_status == TRUE_ONLY; evaluation_status == COMPUTED;

outside window answers neither

Arxo Law

test "outside window answers neither" {
    given {
        context { legal_time @2026-10-01; decision_time @2026-09-13T09:00:00Z; knowledge_time @2026-09-13T09:00:00Z; timezone "UTC";  }
        assert eligible(entity_ref("urn:recipe:m-queries:p"));
    }
    evaluate truth(accepted(entity_ref("urn:recipe:m-queries:p")));
    expect truth_status == NEITHER; expect evaluation_status == COMPUTED;
}

explanation outside window names rule

Arxo Law

test "explanation outside window names rule" {
    given {
        context { legal_time @2026-10-01; decision_time @2026-09-13T09:00:00Z; knowledge_time @2026-09-13T09:00:00Z; timezone "UTC";  }
        assert eligible(entity_ref("urn:recipe:m-queries:p"));
    }
    evaluate why_not(accepted(entity_ref("urn:recipe:m-queries:p")));
    expect evaluation_status == COMPUTED; expect blocked_by(Accept);
}

refuted body names rule

Arxo Law

test "refuted body names rule" {
    given {
        context { legal_time @2026-09-13; decision_time @2026-09-13T09:00:00Z; knowledge_time @2026-09-13T09:00:00Z; timezone "UTC";  }
        assert not eligible(entity_ref("urn:recipe:m-queries:p"));
    }
    evaluate why_not(accepted(entity_ref("urn:recipe:m-queries:p")));
    expect evaluation_status == COMPUTED; expect blocked_by(Accept);
}

applicable rule fires

Arxo Law

test "applicable rule fires" {
    given {
        context { legal_time @2026-09-13; decision_time @2026-09-13T09:00:00Z; knowledge_time @2026-09-13T09:00:00Z; timezone "UTC";  }
        assert eligible(entity_ref("urn:recipe:m-queries:p"));
    }
    evaluate truth(accepted(entity_ref("urn:recipe:m-queries:p")));
    expect truth_status == TRUE_ONLY; expect evaluation_status == COMPUTED;
}

In scene 2 the path results[0].value.value.blockers[0].applicability equals NOT_APPLICABLE, the conjunct list is empty: the rule is outside effective. In scene 3 applicability is APPLICABLE, but trigger is NOT_SATISFIED. Both questions return truthStatus NEITHER. The root GRAPH result has no applicabilityStatus field; a candidate field must not be attributed to it.

Check of result fields and extra inputs:

Python

>>> import runpy
>>> checks = runpy.run_path("docs/recipes/m-queries/resources/check.py")
>>> checks["applicability"](https://github.com/arxohq/law/blob/master/docs/recipes/m-queries/9)
True

Counterfactual

The sidecar mutation reproduces LDC-E1319. Counterfactual table variants are executed separately; input errors are not passed off as NEITHER.

Boundary

APPLICABLE and SATISFIED are different axes. Absence of a rule’s application does not create negative support for its head.

Pitfall

A closed anchor or window lifts application but does not refute the head — see Move a rule onto the edition in force.
