In-cycle fixes for the independent review of the #319 package, RED-first for both Importants. A repeated --override path now refuses at the shared lexer (exit 2, path named) instead of panicking exit 101 through reopen_all — which also un-misattributes the campaign leg's collision prose for duplicates. override_paths' refusal points at aura graph introspect --params (the retired --list-axes reference swept from every live comment, one explicitly-historical mention remains). exec classifies file targets through a Result-bearing peek: unparseable JSON refuses neutrally before any leg is chosen. RunPresentation (single-variant) removed; run_campaign_returning's contract note names its one deliberate usage-class exit; C14's routing sentence and C20's family-builder paragraph amended to current truth (superseded text to the history sidecars); bench error strings and deletion blank-line runs tidied. refs #319
