Vectorize bounded optimizer candidate scoring

Objective

Vectorize bounded optimizer candidate scoring.

Notes: Vectorized exhaustive selection in bounded 256-candidate batches while preserving exhaustive order, deterministic ties, drawdown gates, and sealed holdout. 23 focused tests pass; 2,300-combination synthetic probe measured ~0.016s median versus 0.091-0.133s scalar. Hosted t302 gate remains open.

Approach

[reconstructed — uncertain] No dedicated findings Markdown located for t315. Summary reconstructed from research/findings/task-history.json entry and git history. Uncertain fields: detailed approach, exact file list, and metrics beyond the task note.

Files / code / data changed

• No commit SHA confidently associated with t315 in sampled log [reconstructed — uncertain].
• Task-history entry: research/findings/task-history.json#t315

Results

Task note: Vectorized exhaustive selection in bounded 256-candidate batches while preserving exhaustive order, deterministic ties, drawdown gates, and sealed holdout. 23 focused tests pass; 2,300-combination synthetic probe measured ~0.016s median versus 0.091-0.133s scalar. Hosted t302 gate remains open. [reconstructed — uncertain] No quantitative tables recovered for this entry; see git diff and task-history for grounds.

Conclusions

[reconstructed — uncertain] Outcome inferred from status done and task note.
