# CognitiveEcho

Estimating difficulty via simulation variance

Layer: Mind · Category: Reasoning

## Mechanism

Variance-Based Effort Estimation: [Agent](https://mindscape.pages.dev/bootstrap/Agent.md) runs N rapid, low-fidelity simulations of the task. If outcomes diverge significantly, it triggers decomposition. Ping the problem before solving it. High variance in simulation implies hidden complexity. Process: (1) Generate N quick solution sketches, (2) Measure outcome variance, (3) If variance > threshold, decompose; else execute simplest solution.

## Invariants

- Delay does not exceed short-term memory bounds
- Echo content matches input semantic hash

## Preconditions

- Feedback loop enabled
- Input signal

## Postconditions

- [Signal](https://mindscape.pages.dev/bootstrap/Signal.md) amplified or validated

## Failure modes

- Correlated Hallucination: All simulations are wrong in the exact same way (low variance, high error).
- The simulation model might be too simple to catch edge cases (false negative).
- [Simulation](https://mindscape.pages.dev/bootstrap/Simulation.md) cost may exceed just trying the task for truly simple problems.
- Sample count is arbitrary - tuning required.
