# Session 2026-04-30: test_extreme_orientation_mixed

## Changes Made
- Refactored `test_extreme_orientation_mixed.cpp` from 7 TEST_CASEs to 1 SCENARIO with 8 SECTIONs
- Created TOML 1.0 config (`tests/test_extreme_orientation_mixed.toml`)
- Created precalc script (`scripts/precalc_extreme_orientation_mixed.py`) using sim_engine.Simulator
- Consolidated loop variables using `std::array<Spacecraft*, 5>` instead of 25 individual vars + 5 arrays
- Replaced trivial `REQUIRE(r > 0)` / `REQUIRE(v > 0)` with precalculated value assertions
- Added named tolerance constants: `VDOT_TOL = 1e-3`, `MAT_TOL = 1e-10`
- Added comments to reasonable safety checks (sqrt guard, angular momentum, rotation matrix behavior)
