Keep the loaded cutter layout stable across supported window sizes, preserve recovered encoder choices during capability discovery, and reject unsupported video selections without changing the active project.
Honor the Windows system theme, fully localize runtime metrics, invalidate imported System Check state safely, and bound child-process shutdown waits when close events never arrive.
Extend focused and Electron smoke coverage and prepare the v1.0.17 public release metadata.
Start process-exit waits only when pause or cancellation begins, escalate stubborn children without resolving before close, latch pause across late registrations and fast resume, and retry concat only after a complete resume. Add real child-process and filesystem integration coverage for pause, shutdown cleanup, and persistence order.
Track Streamlink and FFmpeg resources by queue item so parallel jobs can pause, resume, cancel, retry, and clean up independently. Gate queue scheduling during shutdown, await the active queue owner, retain retry artifacts on ordinary failures, remove partial outputs on cancellation, and flush queue state once after active work settles.
