+"""The end-to-end test (Development Plan M1.6): the whole agent, assembled as
+it runs in production, against real models, the Gitea sandbox and a real
+build host, driven by a scripted operator.
+
+It automates the checks of bring-up run 3:
+- a milestone reaches a PR on the sandbox that contains only the work, no
+  build artifacts (#80), pushed with the push credential;
+- the clone on the build host holds no credential (#89);
+- after the milestone, the planner's view carries the orchestrator's facts
+  and none of the executor's turns (#78).
+
+Only the Matrix transport is replaced, by the in-memory one: the operator's
+Matrix credentials are not something a test should hold. Run it with
+scripts/e2e.sh after each milestone; it spends model tokens and takes minutes.
