WO-01: quick independent review (Claude)

7 October 2026 · Scope: quick review requested by the owner, not the full line-by-line Sunday review.

Check	Result
Fresh build from source, Release, -Wall -Wextra -Werror (separate scratch build directory)	built with no warnings
CTest (rl_unit, rl_differential)	2/2 passed
Golden file e46/golden/wo01-golden.json touched since its creating commit 656f9f3?	no
Step function (e46/src/rl_detail.hpp) against RL-V3-PAPER.md §1	matches term by term: z, clamp, floor division (with a compile-time check that signed >> rounds down), v′ and x′ rotations, all lanes from the old state, fold rotations 0/29/61/97
Surprise exam: 3,028 fresh messages (up to 5,000 bytes, plus all-0x00/0xFF runs at shard boundaries), from a random seed that was never recorded; v2 and v3; one-shot and three streaming chunk sizes; checked against the Python references	48,448 digest checks, 0 mismatches

Verdict: WO-01 does what its report says. Items left for the full Sunday review: API/streaming contracts in detail, length limits, the fuzz harness, the benchmark method, and the §2 / §2b PoW wording the report flags for reconciliation.
