kenneth	08dd437952	feat: add caching to FeedEngine ... Add lastFeed() method that returns cached FeedResult within a configurable TTL (default 5 min). refresh() always fetches fresh data and updates the cache. Periodic auto-refresh via recursive setTimeout when engine is started. Reactive updates reset the timer to avoid redundant fetches. Co-authored-by: Ona <no-reply@ona.com>	2026-02-24 01:13:41 +00:00
kenneth	699155e0d8	feat: add actions to FeedSource interface ... Add listActions() and executeAction() to FeedSource for write operations back to external services. Actions use arktype schemas for input validation via StandardSchemaV1. - ActionDefinition type with optional input schema - FeedEngine routes actions with existence and ID validation - Source IDs use reverse-domain format (aris.location, aris.tfl) - LocationSource: update-location action with schema validation - TflSource: set-lines-of-interest action with lineId validation - No-op implementations for sources without actions Co-authored-by: Ona <no-reply@ona.com>	2026-02-15 12:53:10 +00:00
kenneth	1f2920a7ad	refactor: make fetchContext required on FeedSource ... Sources that cannot provide context now return null instead of omitting the method. The engine checks the return value rather than method existence. Co-authored-by: Ona <no-reply@ona.com>	2026-02-14 16:20:24 +00:00
kenneth	181160b018	feat(core): add FeedEngine for FeedSource orchestration ... Introduces FeedEngine that consumes FeedSource instances and manages the dependency graph for context flow and item collection. - Validates dependency graph (missing deps, circular references) - Topologically sorts sources for execution order - Runs fetchContext() in dependency order, accumulating context - Runs fetchItems() on all sources with final context - Supports reactive updates via onContextUpdate/onItemsUpdate - Graceful error handling (continues after source failures) Marks DataSource, ContextProvider, ContextBridge, Reconciler, and FeedController as deprecated in favor of FeedSource + FeedEngine.
