 - **Required browser verification:** authorized FlowCV research if accessible, never bypass auth; original JobTracker design at three widths/themes/keyboard/focus.
 - **Required production verification:** existing variants/edit/export/public render smoke.
 - **Status:** `IMPLEMENTED — NOT VERIFIED`.
-- **Blocker:** fresh FlowCV inspection and JobTracker three-width/theme/keyboard checks require a new browser session; production synthetic-variant smoke requires access.
-- **Evidence:** `docs/verification/career-002-cv-builder.md`; V-120–V-125. Save, navigation, custom entries, named controls, persistence and preview failure/retry pass 17/17 focused, 49/49 suites and 184/184 full plus build.
-- **Commit:** `b58cc19`, `a5b74e0`, `2043349`.
-- **Remaining work:** browser/FlowCV/production gates and honest deployed DOCX capability check only. Avoid rewriting already-working features.
