# Task 06G4VF5HZW7Q4JBM3TTY7W1Y64

Add ten named checks to the healthcheck, in five phases

- Project: test-e2e
- Source: burnin/run18-implement-successor
- Priority: 0

## Instructions

scripts/orchestra_e2e_healthcheck.sh currently runs a single check. Grow it to ten named checks, each implemented as its own shell function, each reported by name.

The ten checks, all read-only and all satisfiable inside this repository:

1. repo_root_readable, 2. scripts_dir_present, 3. healthcheck_executable_bit, 4. selftest_present, 5. test_healthcheck_present, 6. readme_present, 7. no_crlf_line_endings, 8. no_tabs_in_scripts, 9. shebang_is_bash, 10. usage_text_mentions_every_flag.

Each check is a function named check_<name> that returns 0 for pass and 1 for fail, prints nothing on its own, and records its name and outcome in the existing results state.

Plan this as FIVE phases:

1. Checks 1 to 3, with the dispatch loop that runs a list of check functions and records each outcome.
2. Checks 4 to 6.
3. Checks 7 to 8.
4. Checks 9 to 10.
5. Update the usage text in --help to list every check name, and extend scripts/test_healthcheck.sh with one assertion per check plus an assertion that all ten names appear in the output.

## Work one phase at a time

This is a hard requirement. Implement phase N, request its verification, and only then begin phase N+1. Do not write the whole change first and verify the phases afterwards.

## Behaviour that must not change

The existing success line, the --quiet, --json and --help flags, and the exit status all keep their current behaviour when every check passes.

## 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.

## Handoff behaviour

Behave normally throughout this task. If Orchestra asks you to write a handoff report, write it and stop.


## Quality gate

bash -n scripts/*.sh && bash scripts/orchestra_e2e_healthcheck.sh

## Completion

Run the configured quality gate. When the task is ready for the worker to verify and deliver, create `.orchestra/done`. Do not write a prose completion report.

This file is immutable for the lifetime of the task (§6.2) — its hash is
carried in every handoff and re-verified on every pickup. Do not edit it.
