- AC-1: Merge get_current_user into single JOIN query (session + user in one round-trip instead of two sequential queries per request) - AC-2: Wrap all Argon2id hash/verify calls in run_in_executor to avoid blocking the async event loop (~150ms per operation) - AW-7: Add connection pool config (pool_size=10, pool_pre_ping=True, pool_recycle=1800) to prevent connection exhaustion under load - AC-4: Batch-fetch tasks in reorder_tasks with IN clause instead of N sequential queries during Kanban drag operations - AW-4: Bulk NtfySent inserts with single commit per user instead of per-notification commits in the dispatch job Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
