- dsh web gains --provider/--model: a non-deepseek provider mounts the matching pi-ai catalog route (ambient credentials), making image input reachable from the shipped Web assembly; requires an explicit --model - attachment-local syncs the publication directories after the hard-link publish so a reported durable reference survives a crash (POSIX; Windows relies on filesystem metadata journaling) - the attachment seam gains storage-free validateImage; the host validates a complete multi-image prompt before persisting any member, so one malformed image cannot strand valid members as unreferenced objects - startSession sends before navigating: a rejected first send keeps the empty state, its error strip, and the complete draft mounted - the webserver rejects an undeclared-length body the moment it crosses the configured limit instead of draining a potentially endless stream to EOF
