-- Let credits-funded orders exist before the cutover.
--
-- `chk_ingested_orders_after_cutover` (migration 0018) refused any row with
-- payment_method = 'credits' dated before 2026-01-09. It was written as a
-- database-level guard for invariant I1, whose stated reason was splits:
-- before the cutover, shared expenses lived in SplitMyExpenses, and
-- re-importing them would double-charge Sonu against carryover transaction
-- 2348.
--
-- That reason no longer holds. Since finance-app 788219b, ACTIVE_OBLIGATION is
-- `ts.settled = false AND t.transaction_date >= '2026-01-09'`, so a split on a
-- pre-cutover transaction cannot assert a debt at all. The guard now blocks
-- something it was never aimed at: the orders themselves, which are ordinary
-- historical spend. 275 of them — $9,799.96 of meals and rides across
-- 2020-2025 — were invisible because the receipt was the only record and the
-- money came from a gift-card balance rather than a card.
--
-- What is NOT resolved, and is accepted deliberately (user, 2026-07-28): some
-- of those orders were funded by ShopBack gift cards that are themselves
-- recorded as expenses, so that portion is counted twice. The exposure is
-- bounded at $3,411.16 (14 loads) and is probably smaller, because the
-- descriptors name no brand — "ShopBack Gift Cards SQ" is a batch code, and
-- the card could be Amazon, Airbnb or Shell as easily as DoorDash. Six are
-- categorised `gifts` and may be real presents rather than self-funding.
-- Reclassifying them on a guess would corrupt correct data to fix a
-- double-count that cannot be demonstrated, so they are left alone; only the
-- ShopBack purchase emails can settle it, joined on total paid.
--
-- The split guard is untouched: this changes what may exist, not what may be
-- owed.
