An exclude pattern that did not compile was skipped with a warning during the backup, which then stored what the user meant to leave out. Config.Validate now refuses it, naming the setting and quoting the pattern, for example exclude[2]: "build[" is not a valid exclude pattern: ... The compile step moves to config.CompileExcludePattern, which Validate and the scanner both call. The scanner's skip-and-warn path is gone; a pattern that does not compile there now fails the scanner. Model: opus-5-5
