Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# tests/harness - shared helpers every test file imports

Owns the helper modules the suites build on: the concurrent `test()`, the subprocess runner, temp dirs and throwaway git repos, PATH stubs, shell discovery, platform capability probes and PNG fixtures. It holds no test case: its own proof is `tests/harness.test.ts`, one level up.

## Terms

- **Capability probe**: `canDenyRead()` (`perms.ts`) and `canSymlinkDir()` (`symlinks.ts`) answer from one real attempt on a throwaway file, memoised per process, never from the platform name; `false` is a test's skip condition, never a failure.
- **Shell**: an interpreter path or a `[path, ...prefixArgs]` argv (`busybox sh`, `bash --posix`); `forEachShell` yields either form and `RunOpts.shell` accepts both as-is.

## Relationships

- Imported by every test file through a relative `.ts` import. Internal chain: `stub.ts` -> `tmp.ts` -> `run.ts`; every other module imports only Node builtins (`png.ts` encodes through `node:zlib`, no image library).
- `tests/harness.test.ts` covers `run`, `tmp`, `perms`, `stub`, `shells` and `png`; `paths.ts`, `symlinks.ts` and `coreUtilsPath()` have no case there, and `canSymlinkDir()` has no importer.

How to install

The exact contents, by fingerprint

mdr add p2p2sp/p2p2.claude/tests/harness/CLAUDE.md@sha256:31a432b09ae1ac36

The line at the top of this page pins the label git:20261007.b7374d4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
