From db61a83f066ea4c3b694b536d4d9eb0662b3dbf9 Mon Sep 17 00:00:00 2001 From: Julien Calixte Date: Tue, 19 May 2026 14:52:43 +0200 Subject: [PATCH] =?UTF-8?q?fix(qfd):=20correct=20=C2=A74=20roof=20matrix?= =?UTF-8?q?=20size=20and=20glyph=20convention?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two stale bits in §4's preamble. (a) "15×15 roof matrix" still referenced H14's pre-retirement column count — corrected to 14×14. (b) The symbol legend named classical QFD glyphs (◎ ○ × ⊗) but quality-house.md's roof actually renders ASCII (++ + − −−). Both listings now lead with the ASCII glyphs that match the source of truth, with classical equivalents kept in parens. --- docs/qfd.md | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/docs/qfd.md b/docs/qfd.md index 3ba011b..15b15aa 100644 --- a/docs/qfd.md +++ b/docs/qfd.md @@ -159,11 +159,11 @@ before the runtime decision does. ## 4.
