# HeuristicSnap

Rapid, low-cost decision making via pattern recognition

Layer: Mind · Category: Reasoning

## Mechanism

Fast pattern matching against a [Cache](https://mindscape.pages.dev/bootstrap/Cache.md) of past experiences. Returns a decision in <100ms based on similarity to past success, bypassing expensive reasoning chains. It bypasses the expensive [ChainOfThought](https://mindscape.pages.dev/bootstrap/ChainOfThought.md) when [Budget](https://mindscape.pages.dev/bootstrap/Budget.md) is low, relying on cached pattern matches.

## Invariants

- Confidence Floor: Do not snap if similarity < 0.6
- Speed over Accuracy: Latency must be < Threshold

## Preconditions

- A [Cache](https://mindscape.pages.dev/bootstrap/Cache.md) of past experience exists and is queryable

## Postconditions

- [Decision](https://mindscape.pages.dev/bootstrap/Decision.md) made instantly

## Failure modes

- False recognition: a [Problem](https://mindscape.pages.dev/bootstrap/Problem.md) scores above the confidence floor while differing structurally from the cached case, so the cached [Decision](https://mindscape.pages.dev/bootstrap/Decision.md) is imported with assumptions that do not hold. Similarity is not [Equivalence](https://mindscape.pages.dev/bootstrap/Equivalence.md).
