+### Added

+
+### Fixed

+- **Snowflake Cortex not visible before authentication** — provider now appears in the provider list even when not yet authenticated (#447)
+- **New user detection race condition** — first-run welcome flow and telemetry events could fire out of order or be skipped entirely (#445)
+- **52 CI test failures from `mock.module` leaking across files** — test isolation fix for the new `check` command e2e tests (#460)
+- **Missing `altimate_change` marker** — added required upstream marker on `isStatelessCommand` guard to pass Marker Guard CI (#457)
+
