0009: The primary work region uses responsive vertical lanes
Status: accepted for the native vertical slice.
The middle 60% work region shows one vertical lane in compact windows, three at normal desktop widths, and five when at least 2800 px remains after the sidebar. A 3440 px ultrawide therefore presents five lanes. A sliding window over the six comparison panes always keeps the selected pane visible.
This is not a return to the original 2×3 dashboard. Every lane receives the full work-region height, the surrounding context and decision bands remain stable, and only the selected lane owns keyboard input. Clicking a lane selects it. Pane processes and output continue independently of selection.
Terminal geometry is computed from the actual width of one lane, including gaps and insets. The selected real PTY is resized through the runtime actor when the responsive lane count or window bounds change. On the 3440×1440 reference display the current fixed-cell spike derives approximately 71 columns by 40 rows per lane.
The first actor slice still owns one real PTY and five deterministic comparison surfaces. Promoting the runtime boundary from one actor to a pane-indexed session registry is required before all five visible terminal lanes can own independent real processes.
