Health checks reuse a two-second snapshot and bound the schema query. Task SSE writes an error frame when an event cannot be encoded. ResolveDocTask errors when the frozen plan has no duty row, while explicit none-duties stay zero. Drop the unwired semantic-summary replace env, record the intentional dev versus release model split, document the test/main cutover path, and archive pre-goose SQL.
