-Run a single named check with --only
+Describe each healthcheck check in one line
 
 - Project: test-e2e
-- Source: gitea:test-e2e/26
+- Source: gitea:test-e2e/24
 - Priority: 0
 
 ## Instructions
 
-Give scripts/orchestra_e2e_healthcheck.sh a `--only <name>` flag that runs a single named check instead of all ten, then prints the usual success line.
+scripts/orchestra_e2e_healthcheck.sh now runs ten named checks. Give each one a one-line description, and print those descriptions where the names are already printed.
 
-Behaviour:
+The descriptions, one per check:
 
-- `--only repo_root_readable` runs that check alone and exits 0 when it passes.
-- `--only nonsense` prints `unknown check: nonsense` on stderr and exits 2.
-- `--only` composes with `--summary`, `--json` and `--quiet`, each keeping its current shape over the single result.
-- Without `--only`, every existing flag behaves exactly as it does today.
+- repo_root_readable: the repository root exists and is readable
+- scripts_dir_present: the scripts directory exists
+- healthcheck_executable_bit: this script is executable
+- selftest_present: the selftest script is present
+- test_healthcheck_present: the healthcheck test is present
+- readme_present: README.md is present
+- no_crlf_line_endings: no tracked text file uses CRLF endings
+- no_tabs_in_scripts: no script indents with tabs
+- shebang_is_bash: every script declares the bash shebang
+- usage_text_mentions_every_flag: the usage text lists every flag
 
-Plan this as FIVE phases:
+Where they appear:
 
-1. A helper that resolves a name to a check function and reports whether the name is known.
-2. Flag parsing for `--only <name>`, with the unknown-name refusal and exit 2.
-3. Running the single resolved check and recording its result through the existing results state.
-4. Composition with `--summary` and `--json`.
-5. The usage text in `--help`, and assertions in scripts/test_healthcheck.sh for each behaviour above.
+- `--list-checks` prints `<name>: <description>`, one per line.
+- `--help` prints the same description beside each name in its Checks section.
+- `--summary` is unchanged and keeps printing `<name>: ok`.
+
+Plan this as FIVE phases, two checks per phase, in the order listed above.

+## Behaviour that must not change

 ## Research first
 
 Establish at least three findings with distinct confidence: at least one fact, one inference, one assumption.

 Behave normally. If Orchestra asks you to write a handoff report, write it and stop.
 
 Acceptance:
-- `--only <name>` runs exactly one check.
-- An unknown name exits 2 with a message on stderr.
-- `--only` composes with `--summary`, `--json` and `--quiet`.
-- Every existing flag is unchanged when `--only` is absent.
+- Each of the ten checks has a one-line description in exactly one place in the script.
+- --list-checks prints name and description for all ten.
+- --help lists all ten names with their descriptions.
+- --summary, --timing, --strict, --json and --quiet behave exactly as before.
