Health checks reuse a two-second snapshot and bound the schema query. Task SSE writes an error frame when an event cannot be encoded.

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.
