+Completed 2026-06-27: implemented the direct activity-core Core Hub path in
+`ACTIVITY-WP-0017` via a `core-hub-interaction-event` ops evidence sink.
+The sink reads runtime credentials from `CORE_HUB_RUNTIME_TOKEN_FILE` or a
+named environment variable, posts sanitized ops-inventory probe metadata to
+Core Hub `/api/v2/interaction-events`, verifies the event is visible, and
+returns only non-secret ids/statuses. Verified with activity-core unit tests
+and a disposable local Core Hub runtime that accepted an
+`ops-endpoint-verified` event from activity-core and listed it back. The
+deployed activity-core smoke still requires approved `CORE_HUB_BASE_URL`,
+runtime token, and widget id/mapping, so `CORE-WP-0004-T04` remains the
+deployed execution gate rather than an implementation blocker.
