Month 2025-08 recap for fusedio/udfs: Focused on stabilizing logging and clarifying observability in crop index mapping. Implemented a targeted bug fix to suppress verbose cache logging by forcing cache_verbose to False in the int_to_crop call within crop_stats, reducing log noise and potential performance impact. This change preserves functional behavior of crop mapping while improving log quality and observability. Evidence of work is captured in commit 6b612aa7252a03ad3bb45c5c3fac40b88e98e624 ("remove cache msg (#1183)").
