+Live release evidence:

+- implementation commit `115f9850a703b3941b31d133e8547bf18ca37bff` was
+  built as immutable AI image
+  `geointel-all-in-one:115f9850a703b3941b31d133e8547bf18ca37bff-ai`;
+- the container became healthy, the live migration smoke passed against
+  PostGIS 3.6 with Alembic head `202607160001`, and the frontend proxy returned
+  the public session envelope while rejecting the protected projects endpoint;
+- a credentialed live journey on `http://192.168.10.150:1202` verified the
+  complete boundary: signed out and blocked, successful login, authenticated
+  project API access, successful logout, then blocked again;
+- Tower stores the operator credential only as a quoted PBKDF2-SHA256 hash plus
+  an independent random signing secret. The plaintext password was not added to
+  Git, documentation, the deployment template or the runtime environment.
