## 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 ffmpeg rejects provider HLS playlists with extensionless CDN segments, Kaizoku falls back to a StrawVerse-style segment downloader: it fetches the media playlist, downloads and concatenates segments itself, strips short PNG wrappers when present, then remuxes the local transport stream to MP4. Each episode is written as a temporary `.mp4.part` file and moved into place only after the download succeeds, so failed fallback attempts do not leave broken final MP4 files behind. 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.

Direct ffmpeg attempts also have a timeout guard so stalled HLS inputs can fall back cleanly.
