-- v1.0.9 Day 4 — Backfill hyperswitch_payment_id + payment_status on orders.
--
-- Migration 080 (`add_payment_fields`) wraps its ALTERs in a "skip if
-- the orders table doesn't exist" guard. At the time 080 was authored,
-- orders existed earlier in the migration sequence; that ordering has
-- since shifted (orders is now created at 099_z_create_orders.sql,
-- AFTER 080). Result: in any freshly-migrated DB (CI runs, fresh dev
-- envs, future restore drills) migration 080 takes the skip branch
-- and the columns are never added — even though the Order model and
-- the marketplace code rely on them.
--
-- Symptoms in CI: the periodic ledger_metrics worker
-- (internal/monitoring/ledger_metrics.go:164) logs
--   pq: column "hyperswitch_payment_id" does not exist
-- on every run. The order checkout flow would also fail to persist
-- the payment_id at write time, breaking any reconciliation that
-- depends on the linkage.
--
-- The fix is idempotent (`ADD COLUMN IF NOT EXISTS`) so it safely
-- applies to:
--   - production envs that *did* see migration 080 in the original
--     order (column already there, this migration is a no-op);
--   - fresh envs that picked up the broken ordering (column missing,
--     this migration adds it).
--
-- Adding a backfill at 987 instead of patching 080 in place keeps the
-- migration history append-only — re-running the suite from scratch
-- arrives at the same end state regardless of when the migration was
-- merged.

ALTER TABLE orders ADD COLUMN IF NOT EXISTS hyperswitch_payment_id TEXT;
ALTER TABLE orders ADD COLUMN IF NOT EXISTS payment_status TEXT DEFAULT 'pending';

-- Index supporting the reconciliation worker's hot path
-- (`SELECT ... WHERE status='pending' AND hyperswitch_payment_id IS NOT NULL`).
-- Partial because the universe of pending+linked rows is much smaller
-- than the full orders table.
CREATE INDEX IF NOT EXISTS idx_orders_hyperswitch_payment_id
    ON orders(hyperswitch_payment_id)
    WHERE hyperswitch_payment_id IS NOT NULL AND hyperswitch_payment_id <> '';
