Debug CineScreen capture, cursor, playback, and export issues — logs, recording artifacts on disk, the ffmpeg frame-extraction validation method, and the offline smoother-replay harness. Use when investigating "cursor is off", A/V desync, export problems, or any recording misbehaviour.
Build, test, and iterate on CineScreen — XcodeGen workflow, make targets, stale-module fixes, and verification discipline. Use when building, running, or testing this repo, or when the build fails mysteriously.
CineScreen's sharp edges and invariants — metadata invalidation, zoom-section rules, coordinate spaces, PTS rebasing, AVFoundation callback traps, SwiftUI gesture state, autosave suppression. Read before modifying capture, editor, or export code.
Cut a CineScreen release — version bump, tag, CI pipeline, Sparkle appcast, and the invariants that keep auto-update working. Use when releasing a new version or debugging the release/update pipeline.
