New versions

Change a published pack without losing kids' progress.

Change the pack (by hand, with Claude Code, or "open my pack and…" in a chat).
Keep pack.slug, the objective codes and every card id as they are.
Bump pack.version (1.0.0 → 1.1.0).
Push, check, preview and submit as before.

When the new version is published, it replaces the old one: cards with the same id update in place, removed cards leave the deck, and kids' history keeps what they played. The old version shows as Replaced.

Submit and review

What happens after you submit, and how to answer requested changes.

Family packs

Parents can make private packs for their own kids, live as soon as the checks pass.
