Graham McIntire 2348c48c26 fix(rust/hrdps): replace -lola full-grid extract with -lon point extract ... Production observation 2026-04-29: HRDPS chain steps using decoder::extract_grid (wgrib2 -lola) ran at 1000m CPU for 10+ minutes per task without producing any output. The -lola full-grid interpolation against HRDPS's rotated lat/lon source grid is far slower than against HRRR's Lambert source — wgrib2 appears to rebuild the projection table per record. The probe (lib/mix/tasks/hrdps_probe.ex, deleted in 1da78a80) had already proved that wgrib2 -lon at five Canadian cities completes in under a second. Add decoder::extract_points that uses the same -lon flag for the HRDPS-only point set (~57k cells), batched at 2000 points per wgrib2 invocation to stay under Linux ARG_MAX. run_chain_step_hrdps now calls extract_points instead of extract_grid. The post-extract HashSet filter to hrdps_only_points is gone — extraction is already restricted to those cells. Per-cell wall time should drop from "never completes" to ~30-90 s for 57k cells. extract_grid stays unchanged — it works correctly for HRRR's CONUS Lambert source. Tests: parse_lon_output exercises the wgrib2 -s -lon output shape and proves multi-record / multi-point parsing. parse_lon_segment unit tests cover the undefined-value sentinel and the snap-back rejection that ignores cells wgrib2 returned that don't correspond to anything in the requested batch.		2026-04-29 18:25:40 -05:00
