Debug Mode

Start a session only when the current user invokes $debug-mode, says debug mode, or requests instrumented debugging. Resume whenever an active debug session exists, including after user replies or context compaction. The session becomes active when Step 3 arms the server. It ends only after verified cleanup or explicit abandonment. If neither condition applies, stop before analysis, collection, or instrumentation.

This workflow builds on the sibling trace-mode workflow. It extends location evidence through correction, verification, and cleanup. The sibling scripts require Node.js 24 or later.

The initial stage is:

analyze code -> hypothesize -> trace with trace-mode -> reproduction gate
