From f1213e6f0e47aca5331db99e36ef77956ffc396c Mon Sep 17 00:00:00 2001 From: Jinjing <6427696+AmethystLiang@users.noreply.github.com> Date: Mon, 13 Jul 2026 00:34:14 -0700 Subject: [PATCH] =?UTF-8?q?fix(e2e):=20round-2=20=E2=80=94=20gate=20mouse-?= =?UTF-8?q?probe=20on=20arm=20capability;=20align=20revisit=20budgets?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - terminal-reattach-mouse-mode-leak: xterm binds the enable-mouse-events class and the motion listener together in one _handleProtocolChange; some headless CI renderers never bind it on a warm reattach (core mouseTrackingMode still flips), so the positive control cannot arm. Poll a bounded window for arming, then skip when it never arms (matching the pane-manager/shell guards) instead of failing. - artificial-opencode-terminal-load: the worktree-revisit scenario sampled worst-key and timer drift under ACK-gate-held load but asserted the strict unloaded budgets (worst seen ~2s); switch it to the under-load budgets like its siblings.
