+Minor rather than patch because of one behavioural change worth checking before
+upgrading: **invocation mistakes now exit 2 instead of 1.** A bad flag value, an
+unknown record type, a missing required flag — all of these previously exited 1,
+the same code as an API or runtime failure, and now exit 2 as the documented
+table has always said. A script branching on exit 1 to detect "the command was
+wrong" needs to look for 2. Nothing else in this release changes an exit code,
+and no command changes what it sends to the API.

 ### Added
