Agent briefing

Agent briefing

When you (a coding or triage agent) work on this repository:

1. Read Project restrictions and .github/copilot-instructions.md in the main repo.
2. Never introduce stochastic Miller–Rabin or prime-library engines.
3. Keep determinism — serial and parallel paths must agree on results.
4. Add tests for behaviour changes; use @pytest.mark.slow for multi-second 64-bit primes.
5. Run before claiming success:
   • pytest -q -m "not slow"
   • python benchmarks/check_determinism.py
6. Remind users the project is largely AI-generated and needs human review for critical use.
7. Performance claims: use benchmarks/compare_speed.py (primitive vs optimized).
