# Offline fixture tests for bank-match.sh — no credentials, no network, no writes.
# Proves the PASS 0 tx-id normalization (varchar(50) canonical short form):
#   1. txid-normalize — a long Qonto feed id (~67 chars) matches a règlement whose
#      num was stored SHORT (UUID suffix, what payment-record.sh stores) AND one
#      stored LONG (historical); a Wise numeric id matches unchanged. Every pair
#      is ~19 days apart — far outside the ±7d window — so only the id-based
#      PASS 0 can pair them. Expect exit 0, 3 × [tx-id].
#   2. txid-no-num — same bank movement but the payment has num="" → must NOT
#      match (the id is proof; its absence isn't). Expect exit 1, 0 matched.
