### Fixtures are byte-sensitive

`test/static/` and `test/validators/` contain XML signature fixtures. Canonicalization
and digests depend on the exact bytes, so reformatting whitespace silently invalidates
signatures and the failure can look unrelated. `.prettierignore` excludes both
directories — keep it that way, and never run a formatter over them.

# Tests

- `*.spec.ts` — the Mocha suite. Run with `npm test` from the repository root.
- `static/` — signature fixtures.
- `static/integration/` — fixtures for the integration specs.

## Fixture provenance

Most fixtures under `static/` are signatures this library produced and now asserts
against, but some were generated by other XML-DSig implementations so that the suite
checks interoperability rather than only self-consistency. Those were generated once and
frozen; the tests compare against the recorded bytes, so no second toolchain is needed to
run them.

- `hmac_signature.xml`, `hmac.key`, `hmac-foobar.key` — produced by the JDK's
`javax.xml.crypto.dsig` implementation (Apache Santuario), added alongside HMAC
verification support in `c6f7aaa`.
- `windows_store_signature.xml` — a Windows Store receipt, signed by
`System.Security.Cryptography.Xml.SignedXml` on .NET Framework.

Two throwaway harnesses used to live in `test/validators/` for this cross-checking: a C#
console project driving .NET's `SignedXml`, and a Maven project driving the JDK's
`XMLSignatureFactory`. Neither was run by CI or any npm script, and parts of the C# one
no longer compiled. They were removed in 7.0; see
[#547](https://github.com/node-saml/xml-crypto/issues/547). Recover them from history
with `git show 0409418:test/validators` if a fixture ever needs regenerating.

Use a restore command for validator recovery.

git show 0409418:test/validators displays the historical tree but does not restore its files. Replace it with git restore --source=0409418 -- test/validators, or document an equivalent git archive command.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

In `@test/README.md` at line 26, Update the validator recovery documentation to
use a command that actually restores test/validators from commit 0409418, such
as git restore --source=0409418 -- test/validators, or document an equivalent
git archive command instead of git show.
