A 14-role/75-skill fixture with oversized name/email/URL produced zero horizontal offenders and a 9-page 173,196-byte PDF with extractable final-page text. Custom sections share persisted order; partial pages use ceiling count; stale preview/save/export races are gated | Synthetic data and local Chromium only; authenticated 375/768/1440 app journey, real private CV, production browser binary and DOCX remain unverified | Renderer/PDF repository scope verified; application-browser and production gates remain |
 | V-166 | Focused/full backend and frontend tests; optimized frontend build/TypeScript; diff review | Repository root / `job-tracker-ui` | Verify an administrator can identify the deployed application version without exposing build metadata in the normal-user UI/API bootstrap | PASS — focused Auth/System 36/36 and AppShell 2/2; backend 640/640; frontend 53 suites/221 tests; production build passes. Configured version/commit reaches admin `/api/auth/me`, normal users receive no configured metadata, and the responsive header badge is absent unless the admin-owned prop is supplied | Local/JSDOM evidence only; remote CI and deployed version comparison remain.

Website path/query, remote location, free-form date, custom language and incomplete WIP entry round-trip; oversized website is rejected explicitly | Local SQLite/JSDOM only; no real private CV/model/provider/production data.

Chromium computed white on Modern blue, black on `#f8fafc`, white on Technical sidebar, with zero element overflow. A 14-role/75-skill fixture produced a 17-page 259,447-byte A4 PDF with 1,685 final-page characters.
