- Move DB operations from routes/admin.py to services/admin.py (get_logs_context, query_summary_statuses, retry_failed, delete/reset operations) - Add services/jobs.py with Job/JobEvent-based async job queue (create_job, run_job, enqueue_job) - Add services/derived.py with FTS5 reindex and paper index deletion helpers - Refactor scheduler to use job queue instead of direct pipeline calls - Add heartbeat_at/expires_at to TaskLock for lock health tracking - Remove DESIGN_REVIEW.md - Update tests: remove redundant integration tests, add unit tests for new services
