Dam 100602 reports 87798% storage on some days, overflowing
NUMERIC(6,2) and discarding the entire 33-dam daily batch. storage_pct
is now NUMERIC(8,2) (auto-migrated on connect for existing Postgres/
MySQL tables) and every measure column is bounds-checked before insert
so out-of-capacity junk becomes NULL instead of a batch-killing error.
Rerunning the backfill repairs the days the overflow skipped.
POST app.rid.go.th/reservoir/api/dams (open, archive >=2009) collected
hourly into rid_dams + rid_reservoir_daily; backfill script fetches only
missing days so reruns repair holes and are safe alongside the live
collector. /api/stats counts the new table via an engine fallback that
works when HII collection is disabled. Mae Ngat (DAM_ID 200103) hit 113%
usable capacity with ~19 MCM/day inflow in the Oct 2024 flood — candidate
features for the next retrain.
