# Offline tests for payment-record.sh's transaction_id normalization — the writer
# side of the varchar(50) fix (Dolibarr's num_payment columns truncate at 50 chars,
# Qonto ids run ~67). Uses tests/stub-dol-write.sh via the DOL_WRITE env hook, so
# NOTHING is written to the sandbox or prod.
#   1. Long Qonto id  → POST carries the UUID suffix; JSON reports it; stderr says so.
#   2. Wise numeric id → passes through untouched, no normalization notice.
#   3. Id still >50 chars after normalization → refused BEFORE any POST, error
#      cites varchar(50) (never a silent truncation).
