Historical rainfall data
Rainfall coverage: 1901–2015
Descriptive subdivision rainfall totals used for Navanāyaka quantity checks currently cover 1901–2015.
Classical source status
Canonical rules are source-locked in the chapter libraries. Unresolved interpretations remain labelled rather than invented.
Limitations
External reports provide independently documented context and may cover broader geography than Kerala onset. Rainfall descriptive coverage currently ends in 2015. One astronomical year in the replay remains unresolved. Meghādhipati seasonal totals do not currently show a robust universal weekday-ruler effect.
