-- **Exact current task:** commit/push lossless Career manual-field persistence, then correct CV header/sidebar contact contrast before returning to JOBS-002 closure.
-- **Last completed step:** separated strict extraction normalization from lossless reviewed-profile persistence and routed Career save/version/restore/import-merge/legacy consumers through the correct boundary.
-- **Files currently modified:** structured profile persistence/validation, Career and CV/job projection consumers, Career/import regressions, architecture and work-programme evidence.
-- **Commands already run:** failing Career round-trip reproduction; affected backend 112/112; full backend 642/642; Career/Profile UI 17/17; diff check.
-- **Test results:** all corrected commands pass. One initial Jest invocation named two nonexistent test paths and returned “No tests found”; the correct Career/Profile files then passed 17/17. Jest retains the documented force-exit/open-handle notice.
+- **Exact current task:** commit/push the CV contrast/public-render hardening increment, then continue JOBS-002 parity and regression closure.
+- **Last completed step:** fixed header/sidebar contact contrast, added automatic custom-accent foreground selection, and restricted public renderer colour/font overrides to safe supported values.
+- **Files currently modified:** CV settings normalization, themed renderer, renderer regressions and CAREER-002/work-programme evidence.
+- **Commands already run:** failing renderer contrast reproduction; renderer/settings 25/25; full backend 644/644; CV Builder/public UI 22/22; real Chromium computed-style/overflow and 17-page PDF proof; diff check.
+- **Test results:** all repository tests listed above pass. Chromium computed expected white/dark/white foregrounds for Modern/default, Modern/light override and Technical/sidebar, with zero overflow; the 259,447-byte A4 PDF has 17 pages and extractable final-page text. Jest retains the documented force-exit/open-handle notice.
 - **Services currently running:** none on task-owned ports 3000/5202. Playwright stopped its disposable API/Next servers. Pre-existing Docker services were not changed.
 - **Temporary files or processes:** no task-owned process is running and the failed disposable migration database was removed. Existing synthetic browser evidence/account and startup-created local backup remain documented. No provider account, real email, private content, paid service or production service was accessed.
 - **Production changes currently active:** none. No deployment, migration, provider connection/sync/send or production payload occurred.
 - **Rollback status:** downgrade `20260810080858_AddEmailDraftClientRequestId`, then `20260810075206_AddEmailDrafts`, before reverting draft commits; then follow the existing MAIL rollback order (`ee5ef7e`, `449faeb`, `123fc55`/`e9937ac`, ledger downgrade before `653f011`). No production migration/deploy/provider grant occurred.
-- **Uncommitted changes:** V-167 Career reviewed-value persistence and tracking update; no dependency/schema/config/migration change. V-166 is committed/pushed as `a6cffe0`.
+- **Uncommitted changes:** V-168 CV contrast and renderer-setting hardening; no dependency/schema/config/migration change. V-166/V-167 are pushed as `a6cffe0`/`f0b9b22`.
 - **Known failures:** live deployment is not verified because PR deploy is intentionally skipped and the active branch is not approved for merge. Draft export/API/UI, full thread/category actions and non-Gmail review remain; existing accounts need re-consent and IMAP stays read-only. A clean full-chain SQLite apply fails in the pre-existing JT-019 migration before the new draft migration. Browser/provider/MariaDB/production unavailable or unverified; recovery scan performance is unmeasured at large ledger scale; Jest open handles; SEC-006 parser dependency work is still separately gated; parser isolation remains SEC-007.
-- **Exact next action:** review, commit and push V-167; then fix CV contact/header/sidebar contrast with renderer and PDF regressions.
+- **Exact next action:** review, commit and push V-168; then trace the remaining legacy-vs-dedicated Job Details feature parity and close the highest-value JOBS-002 gap.
 - **Work that can continue independently:** the immediate queue in the master plan: Career lossless persistence, CV contrast, JOBS-002 closure, cross-app contrast/accessibility, PRODUCT-001 and VER-001. UX/JOBS production, MAIL provider mutations, SEC-006/007 and PROD packages retain their recorded external gates.
 - **Decisions still required from the user:** none for synthetic/code-inspected repository work. Any provider connection or send test, internet/package upgrades, private data, external/paid providers and production actions retain explicit approval/safety gates; SEC-009 retention/legal policy remains unresolved.
