Run the canonical build plus all nine per-project test commands from docs/TESTING.md. Never uses solution-level dotnet test.
Create or re-baseline lean, repository-grounded implementation plans and persistent dev docs when users ask for an implementation plan, technical plan, feature plan, refactor plan, or dev-docs workstream.
Senior CTO review workflow for repository-grounded implementation-plan workstreams used before coding.
Apply project EF Core conventions for repositories, DbContext setup, query filters, migrations, and seeded lookup data.
Create a self-contained HTML artifact focused on a high-quality SVG architecture or system diagram with minimal supporting prose.
Create a pragmatic self-contained HTML plan that organizes the user's plan content visually without expanding the scope unnecessarily.

**/Program.cs, **/*Controller.cs, **/*Handler.cs, **/*.razorValidationExceptionHandler (handles validation exceptions → 400) → GlobalExceptionHandler (catch-all → 500 in prod, full detail in dev). Each returns true to stop the chain once handled.app.UseExceptionHandler() currently runs without a SuppressDiagnosticsCallback override. In .NET 10, handled exceptions may suppress logs/metrics/events by default once an IExceptionHandler returns true. Treat this as an explicit observability decision when editing exception handling.traceId (HttpContext.TraceIdentifier), timestamp (ISO 8601), and correlationId when available. 500 errors hide detail in production.X-Correlation-ID or X-Request-ID from inbound requests, generates GUID if absent, pushes to Serilog.LogContext.
