# Review R002 — Plan review for Step 1: Methodology

Verdict: Approve

## Findings

No blocking findings.

The revised methodology addresses the R001 blockers: results are now TBD, the tokenizer is pinned to a real implementation (`cl100k_base` via `tiktoken==0.12.0`) with an approximation guardrail, prompt-to-call mapping rules are fixed before measurement, and the frozen snapshot/redaction/non-determinism policy is documented.

## Notes for implementation

- When creating the harness, keep the documented canonicalization exact and deterministic; fixture-mode reruns should produce byte-identical catalog counts and response medians.
- Create the referenced prompt, manifest, fixture, and result files in later steps before relying on this doc as executable documentation.
- If the final `tools/list` payload includes additional schema-bearing fields beyond `name`, `description`, and `inputSchema`, either include them in the canonical token payload or explicitly justify excluding them in the results doc.
