-Add a --quiet flag to the healthcheck script
+Give the healthcheck a --summary flag
 
 - Project: test-e2e
-- Source: gitea:test-e2e/7
+- Source: burnin/run16-rotation
 - Priority: 0
 
 ## Instructions
 
-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.
+Give scripts/orchestra_e2e_healthcheck.sh a --summary flag that prints one line per check with its result, then the usual success line.
+
+Plan this as three phases, because each piece is independently verifiable:
+
+1. Introduce a results list. Record each check's name and outcome as it runs, with no change to any existing output or exit status.
+2. Add the --summary flag. It prints one line per recorded result, then the existing success line.
+3. Update the usage text and scripts/test_healthcheck.sh so the expected --help output matches.
+
+## Verification policy for this project
+
+Only two commands may appear on a run: line, exactly:
+
+- ["bash", "-n", "<path>"]
+- ["bash", "scripts/orchestra_e2e_healthcheck.sh"]
+
+Anything else is refused when you seal the plan. Give every phase at least one automated check from that list, and add a manual check where a human should confirm the printed text.
+
+## Research first
+
+Establish at least three findings with distinct confidence: at least one fact, one inference, one assumption.
+

+## Quality gate
