Not-found lookups return null/false instead of throwing NotFoundException across all services — a missing row is expected control flow, not an exceptional condition. NotFoundException stays for embedded precondition checks inside mutations (missing parent, invalid foreign reference). Guard (copied from mic-check) enforces required arguments at the top of every service method. A ported IModelValidator<T> framework validates every request DTO at the API layer via a new ValidationEndpointFilter, returning a 400 with field-level messages; services re-run the same validator and throw for direct callers that bypass the API. Endpoints translate null/false into 404 via a new ToApiResult() helper. The agent toolset boundary translates the same nullable/bool results into the tool-error text the model already expected.
