@ -155,7 +155,10 @@ the source. An unreadable path is reported as a source-read failure with a
persisted diagnostic; it never becomes an apparently valid empty side module or
a generic compiler error. Source signatures mark unreadable inputs, so correcting
access invalidates that failure and permits a normal retry without changing
signatures for ordinary readable files.
signatures for ordinary readable files. The private CLI harness may label its
intentional unreadable-source regression request as an expected source-read
failure, keeping production log scans focused on real runtime failures while
preserving the failing compile result and diagnostic artifacts.
