The bounded-cache writeback wrapper (crate::io::Writer) was added in 0.17.10 and wired into Disc::sweep in 0.17.11, but the other two paths in the crate that write large amounts of data sequentially — Disc::patch and the MKV/M2TS mux — were still operating on raw std::fs::File. That meant the dirty-page burst pathology the wrapper exists to prevent could still bite on slow / network-attached staging during recovery and mux phases. This release plugs those gaps: - Disc::patch (disc/mod.rs:1981) now wraps the reopened ISO in Writer before any seek / write. sync_all on Writer cleanly drains the in-flight chunk before the existing fsync. - mux/resolve.rs MKV and M2TS branches wrap the output File in Writer underneath BufWriter. UHD MKV mux routinely produces 70+ GB of sequential output; the page cache no longer absorbs that as a single hot blast on slow targets. Mapfile, log, settings, history, and stream-pipeline byte buffers remain unchanged: those are either small one-shot writes (where the wrapper has zero benefit and adds a stream_position syscall) or already use bounded persistence (mapfile time-batched in 0.17.12). The principle: any path that writes substantial sequential data to a single file uses Writer; trivial writes don't.
