 # Changelog
 
+## 2026-03-05 - 4.1.6 - fix(mod_compiler)
+add diagnostic logging to report dist_ts and output directory contents after each compilation task and after import-path rewriting
+
+- Adds DIAG-CROSSTASK logs to inspect dist_ts subdirectories after each task when not in quiet or JSON mode
+- Adds DIAG-FINAL logs to report directory names and file counts for each successful output dir after import-path rewriting
+- Diagnostics use dynamic fs import and are non-intrusive: gated by isQuiet/isJson and errors are ignored
+
 ## 2026-03-05 - 4.1.5 - fix(diagnostics)
 add diagnostic logging around compilation and unpack to aid troubleshooting
