From 03af5b966fb1a1eb5225c2dabdfb8f7216e0c71e Mon Sep 17 00:00:00 2001 From: cliffhall Date: Sat, 5 Sep 2026 17:39:11 -0400 Subject: [PATCH] Review round 6: 80% does not clear a strictly-compared 0.8 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Copilot, accepted — and the sharpest catch of the six, because it is the rationale contradicting the operator two paragraphs below it. Round 1 rewrote the CHAIN_THRESHOLD comment to say a well-shaped pointer "does clear 0.8" and cited 100%/80% as the evidence. This threshold is compared with `>`, so 80% would FAIL an 0.8 bar; the example refuted the sentence it was offered in support of. It was also stale: 100%/80% was an intermediate build, and the shipped state measures 100%/100%. Both copies now cite 100%/100% as the clearing evidence and keep 100%/80% only as the residual-noise figure, saying explicitly that it is not an example of clearing the bar. While checking the claim I found the docs copy needed the same care for a different reason: `passesThreshold` is strict for the chain and INCLUSIVE for the first move (`rate > t` vs `rate >= t`, skill-eval.mjs :558), and 0.8 is the constant for the inclusive one. So "0.8 is compared strictly" is false as literally read. The docs now say a *chain* bar of 0.8 would be the strict one, name the operator for both, and spell out the consequence at RUNS=5 — only 5/5 passes, 4/5 does not. No functional change; CHAIN_THRESHOLD is still 0.5, still strict.
