 # Changelog
 
+## 2026-03-05 - 2.9.1 - fix(mod_custom)
+use absolute smartfs entry.path instead of joining with dirPath when building fullPath
+
+- entry.path is already absolute (from smartfs); avoid joining it with dirPath which produced incorrect paths
+- Fixes file copy path construction so plugins.fs.file(fullPath).copy(destPath) uses the correct source path
+
 ## 2026-02-24 - 2.9.0 - feat(exports)
 expose mod_custom, mod_output and interfaces from entry; make processSingleBundle public
