## Executive Summary
Over the last year we've been sharing our work leveraging large language models to catch bugs on the fly - a novel approach we call Catching Just-in-Time.

## Why It Matters (Strategic Analysis)
Generating executable test code rather than relying on static LLM code analysis establishes deterministic verification of behavioral changes before code lands in production. This architecture converts off-peak compute resources into continuous bug prevention without delaying active developer workflows.
