Requirement: Refresh and caching
The system MUST cache the latest successful ingestion output and MUST serve the cached data to the site renderer.
The system MUST support periodic refresh on a schedule (at minimum daily) and MUST support a manual refresh trigger.
On ingestion failure, the system MUST continue serving the most recent cached data.
The ingestion pipeline MUST use the cache layer (when configured and reachable) to reduce repeated network and parsing work for external sources (for example, YouTube API/RSS and podcast RSS).
Scenario: Scheduled refresh fails
- WHEN a scheduled refresh run fails to fetch one or more sources
- THEN the site continues to use the most recent successfully cached dataset
Scenario: Manual refresh requested
- WHEN a manual refresh is triggered
- THEN the system attempts ingestion immediately and updates the cache if ingestion succeeds
Scenario: Cache hit avoids refetch
- WHEN a refresh run is executed within the cache TTL for a given source+parameters
- THEN the ingestion pipeline uses cached data for that source instead of refetching over the network
