# PURECheck

Observational four-axis PURE viability check

Layer: Mind · Category: Strategy

## Mechanism

A [Check](https://mindscape.pages.dev/bootstrap/Check.md) specialization of the [PURE](https://mindscape.pages.dev/bootstrap/PURE.md) framework for a candidate [Subject](https://mindscape.pages.dev/bootstrap/Subject.md). Evaluate the same subject and evidence snapshot independently through [Parsimony](https://mindscape.pages.dev/bootstrap/Parsimony.md), [Novelty](https://mindscape.pages.dev/bootstrap/Novelty.md), [Realizable](https://mindscape.pages.dev/bootstrap/Realizable.md), and [Expansive](https://mindscape.pages.dev/bootstrap/Expansive.md), with each axis isolated from every other axis's verdict and reasoning. Apply the corresponding [Criteria](https://mindscape.pages.dev/bootstrap/Criteria.md), [Criteria](https://mindscape.pages.dev/bootstrap/Criteria.md), [Criteria](https://mindscape.pages.dev/bootstrap/Criteria.md), or [Criteria](https://mindscape.pages.dev/bootstrap/Criteria.md) to convert each axis finding into its named [Status](https://mindscape.pages.dev/bootstrap/Status.md), [Status](https://mindscape.pages.dev/bootstrap/Status.md), [Status](https://mindscape.pages.dev/bootstrap/Status.md), or [Status](https://mindscape.pages.dev/bootstrap/Status.md), then return those four results and their conjunctive [Status](https://mindscape.pages.dev/bootstrap/Status.md) to the caller.

## Invariants

- Completeness: Each run returns [Status](https://mindscape.pages.dev/bootstrap/Status.md), [Status](https://mindscape.pages.dev/bootstrap/Status.md), [Status](https://mindscape.pages.dev/bootstrap/Status.md), and [Status](https://mindscape.pages.dev/bootstrap/Status.md); no axis is skipped after an earlier failure.
- Isolation: Every axis evaluates the same unchanged [Subject](https://mindscape.pages.dev/bootstrap/Subject.md) and evidence snapshot in an isolated evaluation context that excludes every other axis's verdict and reasoning.
- Criterion Mapping: Each axis status is Verified when its accepted criterion is met, Falsified when that criterion is not met, and Unknown when the available evidence cannot establish either result.
- Non-Compensation: [Status](https://mindscape.pages.dev/bootstrap/Status.md) is Verified iff all four axis statuses are Verified; it is Falsified if any is Falsified, and Unknown otherwise.
- Determinism: The same [Subject](https://mindscape.pages.dev/bootstrap/Subject.md), four criteria, evidence snapshot, evaluator state, and seed yield the same five statuses.
- Observational: Running the check does not mutate [Subject](https://mindscape.pages.dev/bootstrap/Subject.md), write remediation debt, or alter caller control flow.
