# AdversarialSteel

Dual-advocate verdict generation

Layer: Mind · Category: Strategy

## Mechanism

The [Meta](https://mindscape.pages.dev/bootstrap/Meta.md)-process for adversarial verification. Instead of a single judgment, the [System](https://mindscape.pages.dev/bootstrap/System.md) spawns a 'green advocate' (who constructs the strongest case FOR the idea) and a 'red advocate' (who constructs the strongest case AGAINST). A third [Judge](https://mindscape.pages.dev/bootstrap/Judge.md) [Agent](https://mindscape.pages.dev/bootstrap/Agent.md) renders the verdict only after reviewing both steelmanned arguments. It orchestrates [SteelmanCheck](https://mindscape.pages.dev/bootstrap/SteelmanCheck.md) to generate the opposing arguments and employs [CompatibilityCheck](https://mindscape.pages.dev/bootstrap/CompatibilityCheck.md) to ensure the pro, con, and [Judge](https://mindscape.pages.dev/bootstrap/Judge.md) [Agent](https://mindscape.pages.dev/bootstrap/Agent.md)s share a precise definition of the [Criteria](https://mindscape.pages.dev/bootstrap/Criteria.md) before debate begins.

## Invariants

- Dual Representation: Verdict cannot be rendered without Pro + Con arguments
- Targeted opposition: the red argument must identify the specific claim of the proposal it contradicts. An objection that cites no claim is a strawman and does not satisfy the con requirement.

## Failure modes

- [Judge](https://mindscape.pages.dev/bootstrap/Judge.md) [Agent](https://mindscape.pages.dev/bootstrap/Agent.md) defaults to 'Both sides' compromise (Median Trap).
- Shared blind spot: the [System](https://mindscape.pages.dev/bootstrap/System.md) spawns both advocates, so a gap common to their origin appears in neither argument and reaches the [Judge](https://mindscape.pages.dev/bootstrap/Judge.md) as apparent consensus.

## Caution

Spawned advocates share the same model — collusion risk.
