-Late handoff rig: add a --version line to the healthcheck usage text
+Name the healthcheck success message once
 
 - Project: test-e2e
-- Source: burnin/late-handoff-1
+- Source: burnin/run14-a
 - Priority: 0
 
 ## Instructions
 
-Add the version string to the usage text printed by scripts/orchestra_e2e_healthcheck.sh --help. Keep every existing line and exit status unchanged, and keep scripts/test_healthcheck.sh passing.
+scripts/orchestra_e2e_healthcheck.sh spells its success message inline. Give it a single named constant beside the existing VERSION constant and use that constant everywhere the message is printed.
+
+Behaviour must not change. The plain run, --quiet and --help keep their current output and exit statuses, and scripts/test_healthcheck.sh keeps passing.
