-- Migration: add billing_mode to provider_configs
-- Adds a billing_mode TEXT column with default 'prepaid'
-- After applying, set Gemini to postpaid with:
--   UPDATE provider_configs SET billing_mode = 'postpaid' WHERE id = 'gemini';

BEGIN TRANSACTION;

ALTER TABLE provider_configs ADD COLUMN billing_mode TEXT DEFAULT 'prepaid';

COMMIT;

-- NOTE: If you use a production SQLite file, run the following to set Gemini to postpaid:
-- sqlite3 /path/to/db.sqlite "UPDATE provider_configs SET billing_mode='postpaid' WHERE id='gemini';"
