Migrated from docs/backlog.md (Deferred / OSC 9;4 progress bar).

Blocked on winit. No portable taskbar / dock progress API exists (winit 0.30 has no set_progress_bar), and Linux has no standard desktop progress protocol, so a real indicator would be macOS dockTile + Windows ITaskbarList3 glue with a permanent Linux gap, which the "uniform across OS or omit" rule (non-goals.md) rejects unless a recorded design decision carves it out the way the window backdrop was (pipeline.md "Window transparency and OS backdrops"). Re-check when winit exposes a portable progress API. The decode-only half (parse, relay, flash attention on completion) is cheap but visually near-empty without the bar, so it is not worth shipping alone.

Blocked on winit portable progress API (set_progress_bar). Linux has no standard protocol, so uniform-across-OS would require macOS dockTile + Windows ITaskbarList3 with a Linux gap unless a design decision carves it out (cf. window backdrop precedent).

Revisit when winit exposes a portable progress API.
