Interface and Data Flow

The PSRUI interface can be understood as three layers:

• file and workspace entry points
• the main chart area
• the Processing Inspector on the right

File-to-chart flow

1. you select an archive from the sidebar or the menu
2. the renderer creates a backend session
3. the renderer requests metadata, profile, waterfall, time-phase, and bandpass in parallel
4. the results are stored in Jotai atoms
5. MainPanel decides which chart layout to render

Why previews are non-destructive

PSRUI does not edit the source archive directly.

Processing controls update the active session recipe, the backend materializes a temporary preview archive, and charts always read from that preview instead of the original file.

Responsibilities of the main panels

• Sidebar: file browsing, recent files, workspace entry points
• Main chart area: Profile / Freq x Phase / Time x Phase / Bandpass
• Processing Inspector: drives Zap, Pam, TOA, Cal, and Batch
