 - Saved job-search implementation: tenant-owned NAV search definitions now retain per-vacancy first-seen, last-seen and dismissal state; repeat runs identify only genuinely new results, while one-off discovery remains unchanged. Account export/deletion and provider-safe schema ownership include the new records. Focused backend tests passed 3/3, focused frontend tests passed 6/6, schema/migration gates passed 20/20, ESLint passed with zero warnings, and the optimized Next build/TypeScript passed.
 - Interview debrief loop: interview-stage workspaces now create an explicit, durable debrief in the existing user-owned preparation model, prompting for questions, strengths, improvements, feedback and next steps without generating answers. It remains editable/deletable and is localized in English and Bokmål. Focused backend tests passed 11/11, focused frontend tests passed 13/13, ESLint and the optimized Next build/TypeScript passed.
 - Recruiter relationship view: each company now exposes a tenant-scoped view over its existing recruiter details, active applications, status, message totals and recent correspondence, with direct application navigation and no duplicate contact store. Focused backend authorization/data tests passed 2/2, the frontend interaction test passed 1/1, ESLint and the optimized Next build/TypeScript passed.
+- Offer comparison workspace: active applications in the existing Offer status now appear in a responsive side-by-side comparison of recorded compensation, location, decision deadline, next contact, next action and user notes. Missing facts remain explicitly unknown; no parallel offer record was introduced. Focused frontend tests passed 2/2, ESLint and the optimized Next build/TypeScript passed.
 - Focused frontend: 2 suites, 6 tests passed.
 - Full frontend: 64 suites, 272 tests passed.
 - Next production build and TypeScript: passed.
