Lookup or refresh
One public request with no session identity in scraper evidence.

A user-triggered miss acknowledges acquisition immediately, preserves the observation, and delivers an immutable result later.

Ingestion × JobCache
Purpose
Own every contract that crosses between acquisition and the JobCache product. This is a relationship module, not a second ingestion implementation.
Pathways
| Path | Latency | Contract |
|---|---|---|
| User-triggered lookup | Interactive | Return verified current truth directly when available; schedule missing acquisition explicitly |
| Add or refresh source | Interactive acknowledgement | Preserve the observation before asynchronous enrichment |
| Continuous source discovery | Asynchronous | Pull-based leases with bounded retries and evidence receipts |
| Freshness repair | Asynchronous | Drift and aging create work without rewriting the last verified result |
| Product notification | Eventual | JobCache App receives an immutable result or honest failure state |
Reuse seam
Lease, receipt, retry, capability feedback, content addressing, and result-envelope code can be shared with CareerVector contribution paths. Session identity, product authorization, and JobCache-specific presentation cannot.
Invariants
- The interactive response is never delayed merely to route through a staging store.
- A queued refresh is not represented as fresh data.
- Acquisition failures do not delete the last verified evidence.
- JobCache session IDs do not enter scraper evidence or JobCache Core.
Completion evidence
Trace one user-triggered miss from request through preserved raw evidence, enrichment, publication, App delivery, and UI refresh. Trace the same contract under timeout, duplicate, stale, and rejected-source conditions.
