Hotfix: Merchant alias edge case in UK direct debits
- ✓ Resolved edge case where UK Faster Payments direct debit descriptions with trailing spaces were not matched by the alias disambiguation layer introduced in v4.3.0
- ✓ Corrected a race condition in the Corrections API webhook delivery that caused duplicate webhook events on high-throughput accounts (>5,000 transactions/min)
- ⚡ Reduced median p99 latency for POST /categorise/batch from 340ms to 280ms through pre-warmed model shard caching
