From fa302a3ac6d32020ecc42da7cca553e58e1e41d0 Mon Sep 17 00:00:00 2001 From: wassname <1103714+wassname@users.noreply.github.com> Date: Fri, 10 Jul 2026 21:08:44 +0800 Subject: [PATCH] word_steering: fix clamp fluency overclaim (fresh-eyes catch) Claimed 'C~6 stays fluent, C>=8 spams', but the committed C=6 output degenerates into 'Ihopeyouarehappy!' repetition after a coherent opening (my calib probe only read the first 180 chars and missed the tail). Corrected: C~3 is fluent, C~6 reads happy then collapses, clamp's clean window is narrow (<=~4); C=6 shown as the degeneration edge (like add's C=1.5). Outputs unchanged (comment-only edit).
