postProcess() regridded the coarse ignition raster to flammableRTM each year (fireSense_ignitionPredict.R:191); the mapping is kept in mod and applied by indexing. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CwcjqqK59FmTJscyi7xUqv

IgnitionPredictRunregridded the coarse ignition raster toflammableRTMwithpostProcess()every year (fireSense_ignitionPredict.R:191on development), about 3.6 s a year at 6.7M fine cells in a benchmark. The fine-cell to coarse-cell mapping never changes within a run, so it is now computed once, kept inmod, rebuilt only if the extent, dimensions or crs of either raster change, and applied each year by indexing. New tests compare the fine-grid table and raster with the old regrid for two years on non-round grids with non-flammable and NA cells, and check the rebuild. The full suite passes on the branch (41 tests, 0 failed); on development only the two new tests fail.🤖 Generated with Claude Code
