Async chat processing eliminates 504 timeouts - POST returns immediately,
backend processes in background, frontend polls for results with timestamps.
Scale to ~12 simultaneous chats via 8 uvicorn workers + 16-thread executor.
Parallelized MCP data collection, 2h session cache, 5min tool timeout.
Full dead code cleanup across backend, frontend, MCP, docker, and nginx.
Replace lightweight cis_runner.py with Oracle's official cis_reports.py engine
(6660 lines, 48 CIS + 11 OBP checks). Add granular execution parameters (Level,
OBP, Raw Data, Redact), per-report file storage with category browser, tenancy
filter in Downloads, and individual file download.
Add CIS Engine auto-update: check/download latest cis_reports.py from Oracle's
GitHub repo with automatic patch reapplication (admin UI card + 3 new endpoints).
Save engine version to app_settings on startup.
Update README to v1.8 with new features, API endpoints, and versioning table.
