data track

Key features

• Maze - the main path, failed branches, and turning points fall on the same timeline
• Solid lineBackbone path—the steps and answer nodes through which tool calls are successfully advanced.
• Plain text .jsonl (session format v0 event stream)
• Idle spaces are automatically folded, dense segments are automatically aggregated into the "×N" logo (click to enlarge, and labels are completed step by step), and the progress bar has its own failure heat, so every word of an 8-hour session is still legible.
• Data track - tool call density at each step, Token pulse (cache background + uncached input/inference/output delta column), context pressure curve (70%/90% threshold line, compression event "⌄-N%" annotation, hover to see the true value before and after compression)
