# Show a defeated position

## Intention

I want to see an excluded duty without letting it generate consequences.

## Incorrect form and why it stays silent

```text title="Incorrect form"
// DEFEATED скрывают из positions или публикуют instance_of как у активной нормы.
```

The position is visible with payload and createdBy, but its status literals and links are not published. Without a producer there is no position at all; when excluded it exists as DEFEATED.

## Correct form

```law
language "law.core" version "0.2";
package recipes.zh.r08 version "0.1.0";
namespace "urn:recipe:zh-violation:08";

entity Person;
relation enrolled(p: Person);
relation done(p: Person);
relation excluded(p: Person);
relation followup(p: Person);
rule Primary defeasible { for p: Person; when enrolled(p);
    then duty Main { bearer p; achieve done(p) during [@2026-09-01, @2026-09-10]; };
    unless excluded(p);
}
rule Follow strict { for pos: PositionInstance; for p: Person;
    when instance_of(pos, Main) and bearer_of(pos, p); then followup(p);
}
```

## Counterfactual

Diagnostic mutation `rule Primary defeasible` → `rule Primary strict`: LDC-E4110. Semantic differences are pinned as separate scenes.

## Boundary

DEFEATED applies to the losing ground, not to a lifecycle transition. It is not added to statusHistory; the defeat node must name the losing application.
