Java-to-Zig Migration Testing

Prove two separate claims in order:

1. the entire source test contract and all test assets were migrated without loss and Java/Zig observable results match;
2. Zig-specific risks have additional valuable tests.

Do not use coverage, target test counts, file counts, or two independently green suites as proof of migration completion.

Compose with the Zig skill pack

Use $zig-testing for Zig assertions, leak detection, and test syntax; $zig-build-system for test modules, steps, options, and targets; $zig-concurrency for deterministic synchronization and race/lifecycle tests; and $zig-java-migration for the authoritative object and semantic scope. Load $zig-0.16 or $zig-0.15 according to the pinned repository toolchain.
