test: make sequential regression test platform-portable#97
Merged
Conversation
The byte-identity check (assert_array_equal vs a golden fixture captured on macOS) failed on Linux CI: seeded SpotOptim results are bit-identical only on the same platform/BLAS, and an iterative surrogate trajectory amplifies floating-point rounding into different (equally valid) optima across platforms. Assert portable invariants instead: same-seed determinism (bit-exact within a run), exact evaluation budget (nfev/nit/success), and convergence quality in the golden ballpark. The fixture still supplies the case definitions and the budget/quality references. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Tests (fast)failure on the 1.0.0 release PR (#96).The
test_sequential_equivalence_regressionbyte-identity check (assert_array_equalvs a golden fixture captured on macOS) failed on Linux CI — seeded SpotOptim results are bit-identical only on the same platform/BLAS; across macOS↔Linux the iterative surrogate trajectory amplifies FP rounding into different (equally valid) optima. This is a test-design flaw, not a behavior regression (CI: 1571 passed, only these 2 assertions failed at ~1e-4).Now asserts portable invariants: same-seed determinism (bit-exact within a run), exact eval budget (nfev/nit/success), and convergence quality in the golden ballpark.
test:type → no independent release; the 1.0.0 bump still comes from thefeat!commits already on develop.🤖 Generated with Claude Code
