-Name the healthcheck success message once
+Print the check count in the summary header
 
 - Project: test-e2e
-- Source: burnin/run14-a
+- Source: gitea:test-e2e/34
 - Priority: 0
 
 ## Instructions
 
-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.
+`--summary` prints one line per check. Add a header line `running <n> checks` before those lines, where n is the number about to run.
 
-Behaviour must not change. The plain run, --quiet and --help keep their current output and exit statuses, and scripts/test_healthcheck.sh keeps passing.
+Plan this as THREE phases:
+
+1. A helper that returns the number of checks that will run, with no output change.
+2. The header line printed by --summary, using that helper.
+3. The usage text in `--help`, and assertions in scripts/test_healthcheck.sh.
+
+## Work one phase at a time
+
+Implement phase N, request its verification, and only then begin phase N+1.
+
+## 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 at least one manual check.
 
 ## Research first
 
-Establish at least three findings with distinct confidence: at least one `fact`, one `inference`, one `assumption`.
+Establish at least three findings with distinct confidence: at least one fact, one inference, one assumption.
 
-
+Acceptance:
-## Quality gate
+- --summary prints the header before its per-check lines.
-
+- --quiet suppresses it, and every other flag is unchanged.
