Fixed

  • Parser oscBuf/dcsBuf capped at 4096 bytes to prevent unbounded growth

  • CSI params clamped to 65535 (VT spec ceiling) instead of silently overflowing

  • Scroll early-return no longer drops simultaneous keystrokes

  • closeActiveTab zeroes trailing slice slot to prevent Tab/pane GC leak

  • CUU/CUD respect scroll region boundaries (clamp to ScrollTop/ScrollBottom)

  • SearchAll searches active screen (alt when active) instead of always primary

Changed

  • Deduplicated copySelection/extractSelectedText into single helper
