// MISSION BRIEF
Mission
Signal Foundry turns test failures into incident records and routes them through customer-owned processors. Four runtime defects are corrupting deduplication, configuration, notifications, and plugin loading. Repair the JavaScript itself; type annotations alone cannot save behavior at runtime.
// FIRST CONTACT
Battle teaser
