From 053274afef75ee8efa2e84fa83d6ba2304129453 Mon Sep 17 00:00:00 2001 From: Tomas Dvorak Date: Sat, 19 Sep 2026 08:36:35 +0200 Subject: [PATCH] refactor(fs): move ReplaceMagicVar to fs with named props; drop dead helpers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ReplaceMagicVar only had filemanager callers and took 9 positional params (three same-typed strings, two adjacent bools). It now lives in pkg/filemanager/fs taking a named MagicVarProps. BuildRegexp, BuildConcat and the asymmetric EncodeTimeFlowString pair had no production callers — deleted along with their tests.
