-- Remove dead column district_economics.sat_factor (#1509).
|
|
--
|
|
-- sat_factor = 1 + ((sold_pct - 50) / 100) * 0.30 was computed in 09_macro_and_trend.py
|
|
-- and written here, but was never read by any scoring logic (10_score_v2.py, server.py).
|
|
-- The live market sub-score uses sat_score = min(100, sold_pct * 100 / 70) directly,
|
|
-- so sat_factor double-counts absorption without being applied anywhere.
|
|
-- All code references removed in the same commit as this migration.
|
|
--
|
|
-- NB: ALTER TABLE *IF EXISTS* — district_economics is created by the site-finder
|
|
-- pipeline (09_macro_and_trend.py / server.py), NOT by data/sql migrations, so it may
|
|
-- be absent on the main Postgres. Without IF EXISTS the deploy fails with
|
|
-- "relation district_economics does not exist" (DROP COLUMN IF EXISTS only guards the
|
|
-- column, not the table). Idempotent + safe when the table is absent.
