Go (go/) becomes the primary implementation. The original Python version moves to legacy/ and is kept runnable; new features are still built in both (see the Dual implementation rule in CLAUDE.md). - git mv app.py, scripts/, templates/, tests/, pyproject.toml, uv.lock and build/ into legacy/ - Makefile: Python targets point at legacy/, venv in legacy/.venv, CREDENTIALS_PATH exported for the root .secret/ file - CI and make image build the Python image with legacy/ as context; the Makefile is no longer copied into the image - legacy/.dockerignore moved to the context root so it takes effect - CLAUDE.md, docs/README.md, Go comments, fixture README, capture script and VS Code launch config updated to the new layout Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
