# Memory-constrained simulation explorer

Family 137: One-tape time simulation in two-fifths-power space. First review, 8 October 2026.

## Problem and potential new use

Computability researchers can study time-to-space simulation tradeoffs for the specified machine model.

## Applicability and commercial boundary

Simulation time is unrestricted, so the lower space exponent does not promise practical low-memory debugging or efficient emulation.

## Initial business decision

Defer direct product. Buyer demand and profitability remain hypotheses. This first pass does not establish a validated commercial market.

## Next verification action

Quantify actual time overhead on a small eligible machine and retain it as a research demonstrator.

## Evidence scope
