JobCache App and Core seam

Graph note + Markdown ↗

The product edge owns opaque session state; the shared Core owns public role and ad truth.

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.
