-Add a --quiet flag to the healthcheck script
+Route the healthcheck output through one helper
 
 - Project: test-e2e
-- Source: gitea:test-e2e/8
+- Source: gitea:test-e2e/15
 - Priority: 0
 
 ## Instructions
 
-## Goal
+`scripts/orchestra_e2e_healthcheck.sh` prints its success line from more than one place. Centralise the output so every path goes through one helper, and give that helper an explicit format argument rather than reading a global.
 
-Add a --quiet flag to the healthcheck script
+Behaviour must not change. The plain run, `--quiet`, `--help` and `--json` all keep their current output and exit statuses, and `scripts/test_healthcheck.sh` keeps passing.
 
-scripts/orchestra_e2e_healthcheck.sh already handles --help. Add a --quiet flag alongside it that suppresses the success line and still exits 0. Leave the default behaviour and the --help output unchanged.
+## Research first
 
-## Verification
+Establish at least three findings with distinct confidence: at least one `fact`, one `inference`, one `assumption`.
