+#     (full metadata + focused error trace).
+#   - CONTAINER context: this file NEVER talks to the telemetry API. It writes
+#     two local artifacts that the host picks up after lxc-attach returns:
+#       /root/.install-<SESSION_ID>.failed        → exit code (flag file)
+#       /root/.install-<SESSION_ID>.log.errinfo   → structured error capture
+#     This guarantees the server only ever sees ONE terminal event per
+#     execution - the host's complete one.
