From 6aab53396f5a17bea6ffe72b17440f775d98e1b8 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 1 Jul 2026 20:44:02 +0000 Subject: [PATCH 1/3] Drop em dashes and metaphor styling from the README, scripts, and shared tools Plain punctuation throughout, the forge tagline replaced with a factual one, and sandbox/security-boundary wording instead of jail. Replacements are applied identically across the template and example copies so the CI parity diffs (runners, tools, guardrail Floor 2) stay byte-exact; both example suites pass unchanged.
