Java to Swift Migration Testing

The acceptance objective is identical observable behavior for identical inputs under equivalent environments.

Mandatory evidence dimensions

Maintain independent denominators for:

1. Java production objects and members.
2. Java test files, methods, parameterized/dynamic concrete cases, suites, and disabled tests.
3. Test resources, golden files, schemas, certificates, archives, scripts, and datasets.
4. Full Java/Swift differential cases.
5. Swift-only obligations: optional/bridge boundaries, Codable shape, ownership, actor isolation, Sendable, cancellation, platform conditions, and SwiftPM behavior.
6. Coverage, mutation, fuzz/property, sanitizer, performance/load, security, and platform evidence.

Dimensions 1–4 require exact completeness; dimensions 5–6 add target-language risk proof.
