 - The managed `openchamber` plugin tool uses the expandable path and hides its broad protocol input. The plugin supplies the selected action's human description as the native tool title; the UI renders that metadata without owning an action map. The full versioned result envelope renders through the same neutral JSON summary/tree/raw views as other tools, without a tool-specific output card.
 - `ToolPart` defers expanded content after a user toggle, preventing large tool input/output payloads from mounting during the initial chat render.
 - The rich tool diff preview lives in `ToolPartDiffPreview.tsx` and is lazy-loaded from `ToolPart`. It is the only tool-card piece that imports the `@pierre/diffs` + Shiki rendering stack, keeping that stack out of the eager chat startup graph. While its chunk loads (first rendered diff only) the plain-text patch from `PlainDiffFallback.tsx` renders as the Suspense fallback, mirroring the preview's error fallback. `ToolPart` itself must not statically import `@pierre/diffs` runtime modules or `@/lib/shiki/appThemeRegistry`.
-- Running bash output falls back to `state.metadata.output` until canonical `state.output` arrives. Its fixed-height output viewport follows new output until the user scrolls up, then resumes following when the user returns to the bottom. Live output appends or replaces rewritten snapshots as plain text without worker highlighting; finalized output normalizes ANSI terminal controls with a bounded synthetic-cell budget, bypasses the throttle, and receives the normal one-time highlighted rendering.
+- Running bash output falls back to `state.metadata.output` until canonical `state.output` arrives. Its output viewport grows with the content up to `46vh`, then scrolls and follows new output until the user scrolls up; following resumes when the user returns to the bottom. Live output appends or replaces rewritten snapshots as plain text without worker highlighting; finalized output normalizes ANSI terminal controls with a bounded synthetic-cell budget, bypasses the throttle, and receives the normal one-time highlighted rendering.
 - Thinking/Justification duration is hidden in `sorted` mode (handled in `ReasoningPart.tsx` + `JustificationBlock.tsx`).
