- Remove TODO from simulation.cpp (interpolated burns now implemented)
- Update technical_reference.md: both trigger types now use sub-step
propagation to exact trigger time, not step boundary
- Update hohmann-rendezvous-quantization-fix.md: mark Option A as
resolved, remove outdated quantization fix suggestions
- Update propagation_refactor.md: resolve Issues 3 and 4, replace
interpolated time triggers TODO with code path unification TODO
- Remove make run target from Makefile (agents should not run graphical sim)
- Update AGENTS.md: clarify make test vs make test-build, add Simulation section
- Update technical_reference.md Build System: add tag/name/section filtering
- Add SCENARIO section docs with --section flag and fixture behavior notes
- Use ./build/orbit_test path, rename config_name to tag_name throughout
- Add Mat3 struct documentation
- Update OrbitalElements note: 3D now fully implemented
- Document matrix operations in Physics module section
- Update OrbitTracker with new orbital element fields
- Remove deferred status from Orbital Mechanics documentation
- Remove altitude convenience parameter from body and spacecraft config parsing
- Update test configs to use explicit semi_major_axis instead of altitude
- Remove buggy post-processing loop that added parent radius to all spacecraft
- Result: Semi-major axis now used as-is (correct behavior)
- Test results: Molniya position tests now pass (was failing by 1-11M meters)
- Documentation: Remove altitude references from technical reference
- Planning: Document bug fix decision and implementation details
Changes:
- src/config_loader.cpp: Remove altitude parsing and post-processing
- tests/test_maneuver_planning.toml: Use semi_major_axis = 6.771e6
- tests/test_maneuvers.toml: Use semi_major_axis = 6.771e6
- tests/test_orbit_rendering.toml: Use semi_major_axis = 6.771e6
- docs/technical_reference.md: Remove altitude documentation
- docs/planning/molniya-orbit-test-plan.md: Document bug fix approach
- Correct OrbitalElements struct to match orbital_mechanics.h
- Update CelestialBody and Spacecraft structs to show OrbitalElements field
- Update Config Loader section with orbital elements format
- Add new Config Validator module section with all validation functions
- Update Initialization Sequence to include run_all_config_validations()
- Update config examples to use orbit table instead of state vectors
- Create ui_renderer.cpp/h with all raygui UI panel rendering functions
- Remove UI rendering code from renderer.cpp (421 lines moved)
- Remove UI state fields from RenderState, create separate UIState struct
- Remove raygui dependency from renderer module
- Update main.cpp to initialize UIState and call UI render functions
- Update documentation to reflect new module structure
- Improve separation of concerns between 3D rendering and UI overlays
Add completed camera follow features to implementation plan:
- Camera follow for selected bodies
- Distance preservation when switching bodies
- Proper orbital rotation using camera.up
- Mark all UI implementation phases as completed in ui_implementation_plan.md
- Add UI body selection to completed items in implementation_plan.md
- Move ui_implementation_summary.md to docs/session_summaries/ for better organization
- Renamed src/bodies.h to src/simulation.h
- Renamed src/bodies.cpp to src/simulation.cpp
- Updated all include references in src/ and tests/
- Updated Makefile to reference simulation.cpp
- Updated documentation references

Reduced redundancy across documentation files:
- Condensed implementation_plan.md (236→112 lines)
- Condensed test_verification.md (143→62 lines), updated for 4-body test
- Condensed config_assumptions.md (115→44 lines), focused on active issues
- Removed architecture duplication from CLAUDE.md
- Removed common commands from verbose_project_overview.md
- Added 'make test' target to Makefile
Each file now has a clear, distinct purpose with minimal overlap.
