Running Process Detection

This skill covers how dtwiz discovers, identifies, and correlates running OS processes to project directories. Process detection is the foundation for auto-instrumentation — it answers "what's running and where does it live?".

We want to reliably map instrumented services to proper ports.

Architecture Overview

  otel_runtime_scan.go            # Shared types + project-process correlation
  otel_runtime_scan_unix.go       # Unix: ps, lsof
  otel_runtime_scan_windows.go    # Windows: Get-CimInstance Win32_Process, Get-NetTCPConnection
  otel_process.go                 # ManagedProcess lifecycle (launch, port poll, exit tracking)
  otel_process_windows.go         # Windows child-adoption (leaf PID discovery, watchPID)
  otel_process_other.go           # Unix no-op stub for adoptExeclChildren
