Search all legal evasions in quiescence (bench 5983062) Quiescence previously generated only captures and applied losing-capture SEE pruning in check. Generate every legal evasion and bypass that pruning while checked; return matedIn(ply) when none exist. Keep capture-only generation outside check and retain bound-only TT storage. Add regressions for checkmate without an allocated NNUE state, all four quiet king evasions from a rook check, and a SEE-negative capture evasion. These changes are independent of optional static-eval representation and consumers. Validation: focused AVX2 checked/danger and scalar checked search regressions, including unchanged TT/stack layouts; Python suite (99 run, 5 skipped). Optimized depth-13; depth 14 visited 8366978 nodes. Co-authored-by: GPT 6 <codex@openai.com>

Guard search heuristics and skip static evaluation in check (bench 5401484) Checked nodes carry noEval through the search stack and TT. Main-search futility pruning and the fail-low extension after a reduced parent search previously consumed static eval in check; require present evaluations before using them. Guard improving, reverse futility, null move and correction-history arithmetic likewise, and compute TT-adjusted eval only where needed. Disable qsearch stand pat when static eval is absent. Preserve capture-only move generation and SEE pruning here; full check evasions and qsearch mate recognition are isolated in a follow-up commit. Until then, checked qsearch nodes with no searched capture retain -SCORE_INF. At the hard ply boundary, return a neutral score in check instead of evaluating. Enforce the rawEval precondition with doAssert, including in danger builds. Subprocess tests verify this invariant and absent-eval unwrapping survive there. Validation: focused AVX2 checked/danger and scalar checked tests; exhaustive optional-eval/TT round trips and unchanged layouts; Python suite (99 run, 5 skipped). Optimized depth-13; depth 14 visited 8078278 nodes. Twelve alternating depth-14 pairs on CPU 2 versus the representation-only commit show -1.25% throughput change, 95% bootstrap interval [-7.32%, +3.49%]. Search trees differ, so this measures throughput rather than identical work or playing strength. Co-authored-by: GPT 6 <codex@openai.com>
