KYC/AML integration test harness with recorded provider fixtures

[thlpkee20-wq]

Description

Provider adapters are hard to test end-to-end without live vendor keys. Add a fixture-recording harness that captures redacted vendor traces once and replays them in CI without any secrets.

Requirements and context

• Must be secure, tested, and documented
• Should be efficient and easy to review
• Relevant code: src/aml/amlService.test.ts, KYC adapter tests
• Redaction unit-tested to prove no PII leaks

Suggested execution

• Fork the repo and create a branch
• git checkout -b tests/kyc-aml-fixture-harness
• Implement changes
  • Add recorder helper
  • Add redaction rules
  • Land initial fixtures per provider
• Validate security and correctness assumptions

Test and commit

• Run tests
  • npm test
• Cover edge cases
  • Redaction covers unexpected fields
• Include test output and notes
