- Fix omega = π bug for near-zero inclination orbits (src/orbital_mechanics.cpp:277)
- Added inclination threshold (0.01 rad) before using atan2 path
- Prevents unstable omega calculation when h_vec.y is tiny
- Fix true anomaly trigger firing at wrong location (src/maneuver.cpp:172-213)
- Replaced binary search with O(1) analytical time calculation
- Uses mean motion: n = √(μ/a³) to compute exact time to target
- Added true_anomaly_to_eccentric_anomaly() function
See docs/planning/periapsis_burn_bug_analysis.md for technical details
See docs/periaapsis_burn_test_results.md for test results and next steps
Test status:
- Issue 1 (omega): ✅ FIXED and validated
- Issue 2 (triggers): ✅ IMPLEMENTED, 4 tests fail due to design (expected behavior)
- Full suite: 139 passed, 4 failed (all periapsis burn tests)
Next steps: Decide on test tolerance approach (see docs/periaapsis_burn_test_results.md)
- Combined test_cartesian_to_elements_extreme.cpp (263 lines) and
test_cartesian_to_elements_quadrature.cpp (264 lines) into
test_cartesian_to_elements_advanced.cpp (508 lines, -19 lines saved)
- All 30 test cases preserved (16 from extreme + 14 from quadrature)
- No config files to merge (tests use hardcoded values)
- Convert 64 test assertions from Approx() to WithinAbs() in 2 new test files
- Add WithinAbs() testing guidelines to AGENTS.md
- Fix cartesian_to_orbital_elements(): eccentricity vector calculation,
true anomaly normalization, parabolic semi-latus rectum handling
- Add 2 new test files for edge cases and quadrature points
