# Compose Todo and Subagent widgets through an optional lease
|
|
|
|
Todo owns the combined Pi widget and discovers the Subagents panel through a structural, process-local interface. Subagents retains its standalone widget until Todo claims a callback-identified lease, and Todo verifies that lease before every combined render with `isClaimed(onChange)`. `isClaimed` recognizes only the exact callback for the current runtime claim, so a provider reload or invalidation causes Todo to release and reacquire instead of trusting a stale local handle. This avoids a package dependency across the two extensions, preserves either extension's standalone behavior, and lets reload invalidate stale UI callbacks without losing running subagents.

The optional render seam is `render(width, maxBodyRows?, theme?)`. When composing, Todo passes the exact current Pi theme object as `theme`; the only structural requirement is `fg(color, text): string`, and providers may ignore the third argument for compatibility with older implementations. Todo renders a compact unboxed header and task body. Above 120 columns the panels share a row with a one-cell gap and plain-space padding for a shorter panel; at 120 columns and below they stack with one blank line between sections. Combined layouts cap body rows at a shared ten-line budget.
