From b2034c3e7aa160042233178861e4e4aec37e3046 Mon Sep 17 00:00:00 2001 From: Matthew Goodwin Date: Wed, 23 Sep 2026 19:49:55 -0500 Subject: [PATCH 1/4] relocation prompt: read the ruled 2.1.x dialog, not only the boxed one (RT-257) Claude Code 2.1.281 paints the EnterWorktree relocation prompt under a full-width rule and a Tool use heading with no rounded box. The parser bounded the body by a box top only, so it read the live prompt as no dialog and every board-launched pane that entered an rt worktree by path stalled on an attention gate instead of being accepted. A rule now bounds the body the same way a box top does; a capture with neither still fails closed.

A path or echo split across rows now reads undrivable, so a human answers those (narrow panes), and the keypress only ever commits to a path that sat whole on one row. A rule shorter than some other line on screen is not the dialog's top, since text a command paints is capped short of the pane width.
