Summary of Improvements

1. Multi-Architecture Base Image in src/Dockerfile:

   • Removed hardcoded --platform=linux/amd64 from FROM python:3.10-slim, enabling native ARM64 and AMD64 builds with Docker buildx and build.sh.

2. Automated CI Testing & Safe Dockerhub Publishing:

   • Updated .github/workflows/build-and-push.yml to run a preliminary test job with pytest on Python 3.10, 3.11, and 3.12 before building images.
   • Added docker/setup-qemu-action for cross-architecture builds.
   • Made DockerHub login and image push conditional on non-PR events (github.event_name != 'pull_request'), preventing PRs from failing due to missing secrets.

3. Graceful Shutdown & Signal Handling (SIGTERM / SIGINT):

   • Registered signal handlers for SIGINT and SIGTERM in src/monitor.py.
   • Replaced infinite blocking server.accept() with a 1.0s timeout loop that respects shutdown_event.
   • Updated attack_forward_worker to drain remaining queued attacks on shutdown and joined the worker thread before exit, preventing dropped telemetry when containers stop.
