From 4087e78ebb76ec2fba9f9db73f47f56fb91720bd Mon Sep 17 00:00:00 2001 From: Kilo Date: Wed, 16 Sep 2026 02:39:22 +0000 Subject: [PATCH 1/5] B4-FULL-018: promote to pass; make C backend gate conditional on compiler availability - Promote B4-FULL-013..018 from provisional to pass in full acceptance matrix - Make C backend acceptance gate conditional: skip when no C compiler present - Fix CRLF/trailing whitespace in new fixture and doc files -

A later release must use a new tag and must not rewrite prior tags.
