JobCache

Product outcome

JobCache lets people and organizations interrogate a current, evidence-backed model of the job market. Its value comes from roles and their supporting ads over time, not from a pile of unrelated URLs.

Runtime boundary

• JobCache App owns sessions, saved views, immutable snapshots, sharing, and product UX.
• JobCache Core owns public roles, ads, evidence, facts, embeddings, and shared search.
• Internals is the blueprint label for Core and its processing neighborhood, not another product or package.

Invariants

• Session identity remains in JobCache App.
• Stateless search does not create a session.
• Product-local preferences do not mutate canonical corpus evidence.
• A role-level result remains traceable to its ads and observations.
• Absence, unknown, disagreement, and explicit empty values remain distinct.

Current state

The App API, MCP, UI shell, privacy seam, saved-view and snapshot primitives, Core facade, and CrateDB corpus are live. The complete search experience, recommendation mode, map, commercial workflows, and some aggregate reducers remain target work.

Completion evidence

• Role search and evidence journeys across UI, API, and MCP.
• Session privacy and erasure journeys.
• Corpus lineage from role facts to ads and raw observations.
• Honest freshness and uncertainty presentation.
