Arm the source-completion tail and the fleet obligation in the parent before any tree move; cover the CP0 branch switch, the upstream fork ff and the syntax rollback with the interrupted-pull marker; settle (never drop) the marker on a non-kill git failure; refuse foreign-owned venvs and uncompilable targets before HEAD moves; push the fork only after a validated update; ZIP fallback only from an untouched checkout; journal the ZIP swap so start-of-run recovery finishes or rolls it back and no staging/backup sibling wedges the next run. (cherry picked from commit 584acad44f3d6c552b7c2767d12c612de0436498) (cherry picked from commit c6567ac2d28c421f384d95e1a6fc28912cb30f86)
