Validate Migration Parity

When to Use

• After implementing a new endpoint
• When a Python test fails against the C# rewrite
• When checking whether a migration step is complete
• When summarizing regressions or confirming parity

Procedure

1. Identify the smallest relevant validation scope.
2. Run the narrowest useful command first.
3. If needed, use verify-endpoints.sh as a starting point for manual endpoint checks.
4. Compare the C# behavior with the Python baseline.
5. Report pass/fail results and the likely cause of mismatches.

Rules

• Prefer small validation loops over all-at-once test runs.
• Report exact commands that were run.
• Separate build failures, test failures, and behavior mismatches.
• Do not silently reinterpret mismatches as acceptable.

Output

• Commands run
• Passing checks
• Failing checks
• Likely cause
• Recommended next action
