Measure Custom Meta worker heap and cancellation release gates

Objective

Measure Custom Meta worker heap and cancellation release gates.

Notes: CDP measurement on Chromium 149 at 4x CPU: 74,613-combination production request peaked 11,454,248 bytes above worker baseline; cancellation acknowledged evaluation_cancelled in 6.6 ms. Optimizer 3,800.1 ms and Original Meta 967.9 ms. All frozen gates pass; benchmark asserts memory/cancellation budgets.

Approach

[reconstructed — uncertain] No dedicated findings Markdown located for t345. 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 t345 in sampled log [reconstructed — uncertain].
• Task-history entry: research/findings/task-history.json#t345

Results

Task note: CDP measurement on Chromium 149 at 4x CPU: 74,613-combination production request peaked 11,454,248 bytes above worker baseline; cancellation acknowledged evaluation_cancelled in 6.6 ms. Optimizer 3,800.1 ms and Original Meta 967.9 ms. All frozen gates pass; benchmark asserts memory/cancellation budgets. [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.
