 ## Verification
 
-- Current-baseline 253 related regression tests passed (11 files), 28 voice tests including StrictMode passed, and 31 new upload/lifecycle tests passed: 312 disjoint cases. Final typecheck, focused lint (0 errors; two existing CloudChat warnings), full Renderer/Main/Preload/utility Vite build and project-docs/diff gates passed. Independent review has no open blocker. 17 disjoint Electron scenarios passed: 12 in first run plus 5 targeted reruns after updating inherited timestamp/recovery assertions to the exact current trial contract. Published voice fixture validates WAV transcription, latest-draft append, no automatic prompts, 32px buttons and multi-line growth; layout covers narrow/wide windows, long messages, attachments and stream/stop. Voice screenshot visually inspected by root and QA. Fixture audio never accesses the real microphone or paid provider. Real microphone/provider transcription remains distinct from fixture validation.

Final comparison moved the microphone beside send on the right, matching Code; a fresh full build/typecheck and two targeted Electron reruns passed, including 4px adjacency and 375px layout. Fixture audio never accesses the real microphone or paid provider. Real microphone/provider transcription remains distinct from fixture validation.
