The spawn context inject was sending Enter too quickly after pasting large messages. Claude needs time to process the paste before Enter is sent (Claude shows "Pasted text #1 +N lines" message). Increased debounce timing: - Base delay: 100ms → 200ms - Per-KB scaling: 50ms → 100ms - Max cap: 500ms → 1500ms For a typical 4KB spawn context, this gives 600ms (vs 300ms before).
