Pins Aether 0.793.0, the latest release (aeb stays at v0.325, its latest). 0.793.0 carries the aether#2473 batch, including fixes for issues this repo filed:

  • aether#2476: the AVX2 build with MinGW GCC 15.2 no longer faults. Built and run locally with WinLibs GCC 15.2, -mavx2: the large pyramid, the many pyramids and the joint grid give the same height sums, contact counts and joint count as before. bench/RESULTS.md no longer says the AVX2 build needs GCC 16 on Windows.
  • aether#2475: the imported shift-valued constant in broad_phase (leaf.flag_index & dynamic_tree.MOVED_NODE) no longer warns "unresolved type in codegen" (0.791.0 warns on tests/test_solver.ae, 0.793.0 does not). The code was left as written when the issue was filed, so nothing changes here.
  • aether#2477, aether#2481, aether#2491: the build cache keyed on the C compiler, and the two typecheck holes. These were tooling and diagnostics fixes; this code has no workarounds for them to remove.

Local gate on 0.793.0 (installed side by side): every suite passes and the golden determinism trace matches bit for bit.

0.792.0 was tagged but never published (its Windows release build failed), and the first 0.793.0 release run stalled in the Windows test step; filed as aether#2557.
