• Derived quality options from the formats an extractor actually returns per URL rather than assuming a fixed ladder, filtering storyboard entries that would otherwise surface as bogus resolutions.
• Built job progress that detects whether a download is one stream or a video and audio pair pending merge, weights the passes accordingly, and clamps the reported value monotonic.
• Separated transient extractor failures from authentication walls so retries are spent only where they can help, and inspected the cookie jar for per-site session cookies to report the user's actual state instead of generic advice.
