From 8f643d3a0485d00825d2f0f74802822979909b75 Mon Sep 17 00:00:00 2001 From: James Nightingale Date: Sun, 12 Jul 2026 19:32:24 +0100 Subject: [PATCH] chore: single-source the never-rewrite-history policy as a generated block Replace the hand-maintained history-rewrite guidance with the generated repos_sync:history block (byte-identical canonical text from PyAutoMind/policy/never_rewrite_history.md), so the safety policy is single-sourced and drift-checked. The text stays inline; only the manual copy is retired. Part of the ecosystem standardization (spec 4).
