October 2025 (2025-10) monthly summary for os-autoinst/openQA focusing on needle asset handling improvements. Implemented a targeted fix to ensure Needle assets (/needles/ID/(image|json)) are served locally without redirecting to an external asset domain. The change eliminates incorrect external redirects, improving reliability of needle rendering and asset delivery in test results. The work aligns with user-facing stability and security goals by removing unnecessary cross-domain redirects in asset delivery.
