- Implemented QuestionExpansionService for generating and materializing questions based on combinations and AI distillation.
- Added question metadata classification logic to infer intent and layer of questions.
- Created API handlers for question expansion operations including combination preview, AI distillation, metadata classification, and materialization.
- Introduced database migrations to support new question-related fields and constraints in brand_questions and brand_keywords tables.
- Added caching mechanism for AI distillation results to improve performance.
- Defined JSON schemas for question distillation responses to ensure data integrity.
- shared/cache: add Options/L1/async/metrics/prefix decorators, multi-key ops, Redis pool tuning, and JSON readthrough metrics
- worker-generate: claim tasks via DB lease + heartbeat, requeue stale queued tasks, expire dead leases with refund/cache invalidation
- tenant: version article cache keys so worker recovery invalidations propagate cleanly
- shared/config: expand Redis (pool/timeouts/TLS) and Generation (lease/recovery) configs with defaults

- Added `EnableWebSearch` and `KnowledgeGroupIDs` fields to `KolGenerationSubmitRequest`.
- Updated `Submit` method in `KolGenerationService` to handle new request fields.
- Integrated web search and knowledge group validation based on card configuration.
- Introduced caching mechanisms in `KolPackageService`, `KolPromptService`, and `KolSubscriptionAdminService` to improve performance.
- Implemented knowledge context resolution in `KolGenerationWorker` to enrich prompts with relevant knowledge snippets.
- Added utility functions for handling card configuration in both backend and frontend.
- Created tests for knowledge extraction and rendering to ensure accuracy and reliability.
- Introduced BrandLibrarySummary type to encapsulate brand library limits and usage.
- Updated Brand interface to include keyword_count and question_count fields.
- Implemented brand library limits in the backend, including max brands, keywords, and questions per keyword.
- Added API endpoint to retrieve brand library summary.
- Enhanced BrandsView.vue to display brand library usage and limits.
- Implemented computed properties to manage brand, keyword, and question limits in the UI.
- Updated mutation handlers to invalidate relevant queries upon creating/updating brands, keywords, and questions.
- Added visual indicators for brand, keyword, and question limits in the UI.
- Enhanced error handling for exceeding brand and keyword limits during creation.
Introduce a generic read-through caching infrastructure and wire it into
all major tenant app services to reduce database load on hot read paths.
Key changes:
- Add `DeletePrefix` to Cache interface with memory (prefix scan) and
Redis (SCAN + DEL) implementations
- New `readthrough.go`: generic `LoadJSON` / `LoadJSONWithEmpty` helpers
backed by singleflight to prevent cache stampedes; supports jittered TTL
- New `cache_support.go`: centralized cache key builders and invalidation
helpers for all entities (workspace, brand, prompt rules, schedule tasks,
articles)
- Wire optional cache into ArticleService, BrandService, WorkspaceService,
PromptRuleService, ScheduleTaskService, TemplateService, MediaService,
PromptGenerateService via `WithCache()` builder pattern
- ScheduleDispatchWorker invalidates schedule task cache after dispatching
- ArticleService gains a new `Detail` endpoint with empty-result caching
- Update cmd entrypoints and transport handlers to propagate cache
