When a + deferred tool's schema auto-loaded after the model requested + it, the resulting status toast ("Auto-loaded deferred tool + 'edit_file' after model request.") could render at + `footer_area.y - 1` — which on tight layouts is the bottom row + of the composer area, visibly overwriting the start of the + user's typed text. `render_toast_stack_overlay` now clamps + `max_above` to the gap between `composer_area.y + + composer_area.height` and `footer_area.y`, so when the composer + and footer are adjacent the overlay collapses to zero rows and + the toast is suppressed rather than drawn on top. - **`/sessions` picker highlights the selected row more strongly in dark terminals** (harvested from PR #1493 by **@reidliu41**).
