Conversation
📝 WalkthroughWalkthroughThe change adds timeline clip import through Electron IPC and FFmpeg processing. The video editor exposes the import action, appends the imported clip to the timeline, updates recording state, and preserves the project path when required. ChangesTimeline clip import

clip import validation to use a 0.05-second minimum while preserving the
existing two-frame allowance based on safeFrameRate(source.frameRate). Keep the
surrounding duration comparison and validation behavior unchanged.
- Around line 187-190: Update the cursor telemetry copy error handling in the
import handler so non-ENOENT errors are propagated instead of suppressed. Before
returning failure, remove the promoted video and any partially created telemetry
file; preserve the existing missing-file behavior for ENOENT.

- Around line 37-38: Update the import flow around importTimelineClip to capture
the initial project identity, including videoSourcePath and currentProjectPath,
before asynchronous work. After importTimelineClip completes, refresh
inputRef.current, abort if either identity changed, and use the refreshed state
for buildImportedClipPlan and all subsequent commits.

The catch block only shows a toast. The existingdelete-recording-fileIPC does not acceptrecordly-composite-*paths because it only accepts therecording-prefix. Each rejected import can therefore leave an orphaned video, and possibly its.cursor.jsonsidecar, in the recordings directory until manual cleanup.Add a validated IPC rollback operation for

Description
Adds a focused Import video clip action to the editor's Add Layer menu. The selected video is normalized to the active recording's dimensions and frame rate, appended to a new project-managed composite source, and inserted at the end of the current timeline.
The first version intentionally appends at the end. It does not yet provide arbitrary insertion, imported cursor telemetry, imported webcam tracks, or per-source audio controls. Source audio is consolidated into the composite file during import.
Motivation
Users currently cannot add a missed video segment after finishing a recording. This provides a small, non-destructive path for the common append case without changing the saved-project schema or introducing a multi-source playback architecture.
Type of Change
Related Issue(s)
No existing issue found for timeline clip import.
Screenshots / Video
Not attached. The visible UI change is a single Import video clip menu item under Add Layer; the verification steps below exercise the complete import path.
