Construct automatic unknown identity once at the application boundary.
Validate the original question before adding immutable Evidence scope, and
preserve each result's supporting link through CLI and MCP producers.
Apply the shared policy to derived investigations, managed comparisons and
verification, composed workflow residuals, and process-capture residuals.
This prevents registry conflicts and silent loss of later result links.
Keep explicit creation/update semantics and exact Evidence replays intact.
Cover all affected producer families with public MCP regressions, preserve
snapshot provenance distinctions, and retain blank-question/error handling.
Remove the superseded single-result call-path test.

Use one named input-schema projection for clients and catalog identity, preserve dialect declarations, and bound compact schema depth. Keep canonical SDK output validation when output advertisements are disabled. Release request-owned state on cancellation and carry upstream limitations through composed workflows. Preserve doctor full-output envelopes and validate navigation facts at their owner.

Validation: focused schema, SDK output-validation, context, and workflow tests passed; no schema dialect or canonical output validation was relaxed.
