## Why `codex-core` was being built in multiple feature-resolved permutations because test-only behavior was modeled as crate features. For a large crate, those permutations increase compile cost and reduce cache reuse. ## Net Change - Removed the `test-support` crate feature and related feature wiring so `codex-core` no longer needs separate feature shapes for test consumers. - Standardized cross-crate test-only access behind `codex_core::test_support`. - External test code now imports helpers from `codex_core::test_support`. - Underlying implementation hooks are kept internal (`pub(crate)`) instead of broadly public. ## Outcome - Fewer `codex-core` build permutations. - Better incremental cache reuse across test targets. - No intended production behavior change. |
