## Summary - Implemented Phase 2 propagation primitives (string operations) - Added PropagationPresets for common use cases - Added global configuration system for defaults ## New Components **codepathfinder/propagation.py:** - Added propagates.string_concat() - Added propagates.string_format() **codepathfinder/presets.py:** - PropagationPresets.minimal() - 2 primitives, ~40% coverage - PropagationPresets.standard() - 5 primitives, ~75-80% coverage (recommended) - PropagationPresets.comprehensive() - All MVP primitives - PropagationPresets.exhaustive() - Future: all phases **codepathfinder/config.py:** - PathfinderConfig singleton - set_default_propagation() - set_default_scope() - flows() now uses global defaults when not specified ## Testing ✅ 137 tests pass (38 new tests for Phase 2, presets, config) ✅ 99% coverage (exceeds 95% requirement) ✅ Black, ruff, mypy: all clean ## Breaking Change - flows() now uses global default propagation/scope when not specified - Previous behavior: empty propagation by default - New behavior: uses get_default_propagation() (empty by default, can be configured) 🤖 Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com>
