Keep a persistent Summer World between restarts: checkpoint saves, restore before join, the final save.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /summer-world-saves — a World that is still there tomorrow > **Preview.** > - Verified in Local Play: restore of a new World, commit and receipt. > - **Not** verified: restoring after a real restart. Local Play keeps saves in memory only, so only hosted play proves it. > - Persistent Worlds need hosting support for your game. Check that it is available before you promise it to players. ## Overview Most Summer Worlds are **match-scoped**: the match ends and its state is gone. A **persistent** World is a place players come back to, such as a shared base, a farm or a realm. Its authority can stop for maintenance, a crash or a move. A new authority then restores the World from its last save. | Keep | Use | |---|---| | What belongs to the place: built walls, chests, the coins left on the ground | **World save** (this skill) | | What belongs to a player: their coins, unlocks, level | **Player data** (`summer-player-data`) | The engine never serializes nodes for you. The game decides what one save holds. It must be **one consistent cut**: if an item moves from a chest into an inventory, both sides go in the same save. …

How to install
mdr add summerengine/summer/summer-world-saves@sha256:c0603f8aff8938e2The line at the top of this page pins the label git:20261016.e9d6e70, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
