## Download Flow
Kaizoku stores provider-backed show IDs as `provider:id`, for example `anikoto:some-show-slug`. Queue jobs resolve the episode source through `providers/bridge.js`, then `provider_downloader.py` downloads the media with `ffmpeg` into a staging directory. If a provider returns a master HLS playlist, Kaizoku selects the highest-bandwidth variant before starting `ffmpeg`. When a media playlist uses extensionless CDN segments, Kaizoku skips direct ffmpeg and uses a StrawVerse-style segment downloader: it fetches the media playlist, downloads and concatenates segments itself, strips short PNG wrappers when present, retries temporary HTTP failures such as `429 Too Many Requests`, then remuxes the local transport stream to MP4. Direct ffmpeg attempts also have a timeout guard so stalled HLS inputs can fall back cleanly. Each episode is written as a temporary `.mp4.part` file and moved into the downloads library after that episode succeeds, so already-finished episodes from a larger batch survive if a later episode fails. Retrying that failed queue job requests only the remaining episodes while keeping the original episode range for display and watchlist sync. Finalization preserves episode numbers from staged `SxxEyy` or `Episode yy` filenames before applying configured season/episode offsets.
Kaizoku stores provider-backed show IDs as `provider:id`, for example `anikoto:some-show-slug`. Queue jobs resolve the episode source through `providers/bridge.js`, then `provider_downloader.py` downloads the media with `ffmpeg` into a staging directory. If a provider returns multiple servers for the requested sub or dub mode, Kaizoku tries the same-mode server sources in quality order before falling back to another provider. It does not use sub sources for dub downloads, or dub sources for sub downloads. If a provider returns a master HLS playlist, Kaizoku selects the highest-bandwidth variant before starting `ffmpeg`. When a media playlist uses extensionless CDN segments, Kaizoku skips direct ffmpeg and uses a StrawVerse-style segment downloader: it fetches the media playlist, downloads and concatenates segments itself, strips short PNG wrappers when present, retries temporary HTTP failures such as `429 Too Many Requests`, then remuxes the local transport stream to MP4.

Finalization preserves episode numbers from staged `SxxEyy` or `Episode yy` filenames before applying configured season/episode offsets.
If the primary provider cannot list, resolve, or download a requested episode, Kaizoku searches the same title on the remaining providers and tries the matching episode there. Existing finalization code moves staged files into the configured library layout, preserving data already present in production download folders.
