2026-01-25 - Debug Sandbox Hang And Simplify Module 08

Timeline

  • (Context) Investigated hanging issue in sandbox_pilot.py during daily_handoff.py execution.
  • (Observation) Diagnosed that daily_handoff.py was scanning the entire Linux root filesystem because Docker default CWD was /.
  • (Action) Fixed sandbox_pilot.py by adding -w /app to the docker command and implementing robust subprocess.run with timeout and unbuffered output.
  • (Action) Refactored Module 08 narrative from Security Trap (Hibernation) to AI Interpretation (Log Analysis) per Architect request.
  • (Action) Updated sandbox_pilot.py prompt to act as a Container Interpreter providing human-friendly summaries.
  • (Action) Simplified student-facing prompt.txt to generate a standard Catch-Up Review tool without the hibernation trap.
  • (Action) Updated python-fabrication.md with best practices for Windows-to-Docker orchestration (The Container Bridge).
  • (Action) Formalized self-improvement process by creating self-evolutionary-upgrade-protocols.md.
