Perf Release Comparison Plan

Goal

Produce changeset-ready perf numbers comparing plate-2 vs ../plate, split into nodeId and non-nodeId wins, plus current metrics vs Slate.

Steps

1. Inspect existing perf docs, harnesses, and sibling repo state.
2. Choose a fair comparison method for ../plate.
3. Run current and baseline benchmarks.
4. Separate nodeId-driven wins from non-nodeId wins.
5. Write a concise release summary with exact deltas and caveats.
