- P1 (test/double-book.test.js, real DB, self-cleaning on a dedicated throwaway
place): the migration-007 btree_gist EXCLUDE constraint rejects an overlapping
CONFIRMED stay (23P01), ALLOWS an adjacent '[)' -boundary stay (check_out ==
next check_in), and ALLOWS an overlapping CANCELLED stay (partial WHERE only
guards confirmed/pending). Cleans every inserted row in a finally.
- P2 (booking.test.js): POST /bookings with check_in==check_out, check_out<check_in,
or a non-ISO date → 4xx and NEVER reaches INSERT INTO bookings (C2 route gate).
- P5 (booking.test.js): slot/tour pricing = base_price*guests (happy path inserts);
guests>max_guests and guests<1 → 400 with no INSERT (C1 route gate).
- P3 (webhooks-route.test.js): a replayed Tilopay webhook (same event id) returns
'dup' on the 2nd delivery and does NOT re-run the payments UPDATE / confirmBooking
(programmable mock flips the webhook_events ON-CONFLICT insert to rowCount 0).
- P6 (webhooks-route.test.js): a signed-but-malformed payment body → 400 'bad body'
and ZERO DB writes — asserts the R3 event==null guard (no phantom confirm).
- P7 (webhooks-route.test.js): an ONVO-signed body POSTed to /tilopay → 401, no DB
write (cross-provider signature must not validate).
Also fixes the pre-existing payouts.test.js mkBooking fixture so it satisfies the
new migration-008 CHECKs (bookings_has_a_date + bookings_total_reconciles: adds
check_in/check_out and platform_fee = total - host_payout).
Full suite: node --test → 101/101 green, deterministic, zero leftover rows.
