# LayeredCheck

Hierarchical verification strategy

Layer: Mind · Category: Inference

## Mechanism

A [Check](https://mindscape.world/scapes/bootstrap/Check.md) strategy that evaluates constraints in a declared [Hierarchy](https://mindscape.world/scapes/bootstrap/Hierarchy.md), cheapest first (e.g., existence -> [Validate](https://mindscape.world/scapes/bootstrap/Validate.md) (schema) -> [Understand](https://mindscape.world/scapes/bootstrap/Understand.md) (semantics), which is also increasing abstraction in the common case). It uses a [Sequence](https://mindscape.world/scapes/bootstrap/Sequence.md) of [Gate](https://mindscape.world/scapes/bootstrap/Gate.md)s where lower-level failures halt execution immediately, preventing resource waste on higher-level checks for fundamentally broken inputs.

## Invariants

- A lower layer's failure stops the [Sequence](https://mindscape.world/scapes/bootstrap/Sequence.md); the next layer does not run.
- Layers run in their declared order, cheapest first.
- Each layer declares whether a finding is a failure or a warning.

## Failure modes

- Misordered layers: an expensive check sits below a cheap one, so the halt saves nothing.
- Warning inflation: findings are classed as warnings to keep the [Sequence](https://mindscape.world/scapes/bootstrap/Sequence.md) running, which defeats the halt.
