# ISO 20022 over AS4 — Golden test vectors

Use these as golden request/response pairs for resolver tests. See [testing-strategy](../../architecture/testing-strategy.md).

- **bic-resolution.json** — BIC + iso20022.fi + credit.transfer → primary directive with profile as4.fifi.iso20022.v1.
- **lei-resolution.json** — LEI resolution; evidence may include LEI→BIC mapping.
- **negative-unknown-identifier.json** — Unknown identifier → empty directives, negative_cache_ttl set.

Tests: seed store (or routing artifact) with participant/endpoint for BIC/LEI; run resolve with request; assert output matches expectedResponse (or key fields). Placeholder URLs and cert refs (e.g. https://as4.bankus.com/fi) are for assertion only; replace with test fixtures as needed.
