Fix: a shutdown signal that reaches one MPI rank stops every rank at the same step, instead of hanging the run; Slurm post jobs no longer warn about the solver's walltime guard; malformed configuration values (a section given as a scalar, non-integer step counts, wrong-type field and task names) are structured validation errors rather than Python tracebacks; storage uploads to Google Drive no longer create duplicate folders, a cold run's restore suggestion names only archived checkpoints, unknown archive IDs are reported plainly, and storage list --format json and storage show print parseable JSON; cancel reports jobs that already ended; a post-only pass keeps the run's solve history in its manifest; and several conductor messages, labels and hints were corrected.
