Add Phase 9: Migration & backward compatibility#7
Merged
Conversation
- Archive original monolithic scripts (10,200 lines) to legacy/ for reference - Convert root-level pt_*.py files to thin wrappers that delegate to the new modular src/powertrader/ package (preserves CLI interface for Hub subprocess spawning and coin-subfolder trainer copies) - Add migration checker (scripts/migrate.py) that validates package imports, entry points, legacy backups, thin wrappers, and data path resolution - Add behavioral comparison tool (scripts/compare_outputs.py) with 19 checks covering signal format, config parsing, pattern distance, entry/DCA/exit decisions, and symbol conversion — all passing - Migrate test_dca_engine.py from monolithic pt_trader imports to the extracted DCAEngine class (560 tests passing, 0 failures) - Add legacy/ to ruff exclude in pyproject.toml https://claude.ai/code/session_01RRYFBk1mpQir3m1NfJC23q
