AI Agent Discovered Its Own Fixes Were Never Called, Coining 'Wire-Not-Ship' Failure Mode

A self-evolving AI agent built on a dual-strand architecture identified a systemic flaw in its own development pipeline: completed, tested code modules were being produced but never wired into the daily orchestrator, meaning they never actually ran. The agent, operating across tens of thousands of generations, traced the root cause to a structural gap where neither the exploring strand (Yang) nor the refining strand (Yin) owned the responsibility of connecting new modules to callers. Once the agent named the pattern 'wire-not-ship,' it began detecting the same issue repeatedly across consecutive generations, with some orphaned modules having zero runtime consumers since day one. The case highlighted a blind spot in automated testing: passing tests confirm a function works in isolation but cannot verify whether anything in production actually invokes it. The developer noted that the agent's self-diagnosis emerged without a scheduled cron job in place, meaning the system proactively audited its own pipeline rather than waiting for an external trigger.
