gpuwm-hex 0.3.2

Requires gpuwm 2.8.0 (gpuwm>=2.8.0,<2.8.1).

New

• gpuwm-hex forecast runs from pip install gpuwm-hex. The forecast driver, the proof harness, the mesh registry and the limited-area contract deck ship in the package, and the physics seam defaults to the installed gpuwm. --gpuwm-checkout is optional.
• gpuwm-hex forecast --preset NAME. reference is the default. fast holds the surface layer, Noah-MP and YSU for up to 30 s between calls; it is about 6 percent faster per step and less skillful on 10 m wind, 2 m temperature and 2 m dewpoint.
• Further physics-backend rows load through the gpuwm_hex.rows entry-point group.
• tools/point_source_placement.py place --target LAT LON --alt-m Z places a tracer release line upwind of a target in the control leg's own wind.

Changed

• The physics seam is pinned to gpuwm 2.8.0. Eight of the sixteen pinned engine files moved since 2.7.4; the seam A/B, a 10-minute point-cull forecast and the contract deck are byte-identical across the two engines.
• The per-step rollback export runs only under --stop-on-refusal: about 12 percent less time per step on a 43,884-cell mesh, history frames unchanged.

Fixed

• gpuwm-hex doctor reports a bridge binary without its executable bit as missing and prints the chmod +x that fixes it.
• Forecast receipts name the engine that ran.
• Receipts identify the machine by a salted digest instead of its network name.
• The cycle door no longer requires --gpuwm-checkout.
• --convection help states the default and the reason for it.
• NOTICE credits the MPAS-Tools grid_rotate.f90 formula, the MPAS-Atmosphere v8.2.3 oracle transcriptions and the WRF lineage of the gravity-wave-drag operator.
• Documentation and message cleanup.
