Every #[cfg(test)] mod tests in src/history.rs now uses the new public
API: add_events(iter) / converge() / learning_curve() / current_skill()
/ log_evidence(). No golden value changed.
Legacy methods removed:
- History::convergence(iters, eps, verbose) → use converge()
- History::learning_curves_by_index() → use learning_curve() / learning_curves()
- HistoryBuilder::gamma(f64) → use .drift(ConstantDrift(g))
- add_events_with_prior downgraded from pub to pub(crate)
Added:
- History::builder_with_key() for custom key types (used by atp example)
- tests/equivalence.rs: Game-level golden integration tests
examples/atp.rs rewritten in new API (Event<i64, String>, converge(),
learning_curve(), drift(ConstantDrift(...))).
Bench Batch::iteration: 21.4 µs (T1 reference: 22.88 µs).
