What happens when this goes wrong?
Every other page shows this payment working. Here you choose what breaks, and follow the damage — because a hold, a return or a missed cut-off is the system working as designed, and reading one calmly is the job.
Pick a failure above. Nothing here is invented — each one is a reason code this rail really uses, at the step where it really strikes.
One payment between two directly reachable PSPs on their own TIPS accounts. The customer hold is illustrative bank processing; exact thresholds, T2-to-TIPS liquidity management, reachable parties and non-euro settlement are omitted. Every failure here is authored on TIPS — TARGET Instant Payment Settlement, with the sources that back it.
