Add a pluggable LLM provider with an offline template fallback, prompt builder, contextual match scoring (area/location boosts, availability), per-solution explanations and in-memory request limiting for cost control.
Add a pluggable embedding provider with an offline deterministic default, vector indexing for problems and innovations, cosine semantic ranking, similar cases and solution suggestions, area filtering and an admin reindex endpoint. Refresh the index when innovations or submissions change.
Add knowledge item and innovation CRUD with search/filtering, published-only visibility for non-staff, admin publish/update, challenge dictionary, problem aggregation with trends (admin only) and canonical embedding text preparation for matchmaking.
Add submission CRUD with pagination and role scoping, challenge/location binding, automatic keyword extraction, a validated status workflow, and domain events for matchmaking and notifications. Create a problem record together with each submission.
Add signup/signin with backend-issued JWT (Argon2 passwords in SurrealDB), role-based authorization policies, per-user data access levels, consent register and read audit log. Protect user endpoints and record sensitive reads.
Split the backend into API host, Domain, Application and Infrastructure projects. Add Swagger/OpenAPI per API version, Asp.Versioning (query/header), ProblemDetails with a global exception handler and SurrealQL migrations applied at startup (namespace/database ensured). Infrastructure owns the SurrealDB client, settings and DI.
Add additive schema for demo (user.display_name, innovation.tags, FLEXIBLE free-form fields) and a fully synthetic seed with organizations, personas, problems, submissions, innovations, knowledge items, grant calls, ideas and tester feedback. Verified on SurrealDB 3.2.4: migrations apply cleanly and are idempotent.
Add an idempotent SurrealDB 3.x schema for all domain entities with indexes (HNSW vector and full-text), record access and permissions, plus a taxonomy seed with the 8 social challenges, grouped tags and sample locations. Verified on SurrealDB 3.2.4: migrations apply cleanly, re-run is idempotent and CRUD works.
Add StorageService backed by SurrealDB using the embedded RocksDB provider that persists to ./data (never in memory). Support an optional remote server via SurrealDb:RemoteUrl for frontend sync. Expose readiness and storage probe endpoints under /api/system and add a helper script to start a local SurrealDB server.
Set the backend version to 0.0.1.
