What it is for

application-test-results — a thin Axum HTTP/JSON API over operations_test_results::TestResultsService.

Two consumers: CI/external runners report results in (fat POST /runs/complete in one transaction, idempotency-keyed; or incremental), and a web report UI reads history out (keyset-paged runs, time-ranged metrics). Mount the router into any host via Extension so it never imposes its state type on the host (Gate 1.5 Q4). Tenant comes from the authenticated key, never the request body.

Plan + consensus: docs/userstories/sprint-0.42-test-results-api.md.
