feat: integrate hardened CLOSE yardstick into determinism & teaching regression surfaces
- docs/testing-lanes.md + Makefile: recommended determinism regression invocation (uv run python -m evals.close_derived_climb + contract pytest) as part of standard verification story / rerun flows.
- evals/anti_regression/run_demo.py + tests/test_anti_regression_demo.py: hermetic embedding of the yardstick (lived IdleTickResult flag, semantic determine rule=direct, content_replay_checksum) into the core anti-regression / teaching demo flow (core demo anti-regression now carries + reports the Claim-B signals; active corpus remains untouched).
- Supporting docs: contract.md (uv + refs), anti_regression_demo.md (complementary note), runtime_contracts.md (determination surface cross-ref).
- New ratification artifact (pre-impl) + all success criteria met.
See ratification for chosen approach + why only correct path.
All existing tests/invariants green; hermeticity preserved; no core/engine changes.
