Bound optimizer candidate memory on latency path

Objective

Bound optimizer candidate memory on latency path.

Notes: Optimizer now retains only the current best exhaustive candidate instead of up to 100,000 metrics dictionaries and avoids the final full-list sort while preserving objective-descending/ID-ascending ties, constraints, and holdout semantics. 19 focused tests pass. This is not live latency evidence; t302 remains open.

Approach

[reconstructed — uncertain] No dedicated findings Markdown located for t311. 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 t311 in sampled log [reconstructed — uncertain].
• Task-history entry: research/findings/task-history.json#t311

Results

Task note: Optimizer now retains only the current best exhaustive candidate instead of up to 100,000 metrics dictionaries and avoids the final full-list sort while preserving objective-descending/ID-ascending ties, constraints, and holdout semantics. 19 focused tests pass. This is not live latency evidence; t302 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.
