Ship a hosted Summer multiplayer game: the summer.games bundle, server preset, pre-upload checks, and a new Build.
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.

# /multiplayer-publish — from project to a Build players can join Step 5 of the multiplayer sequence. It assumes the layout from `multiplayer-project`: `summer.build.json`, `world.json`, `runtime-manifest.json`, `source-domains.json`, and the `client/`, `authority/` and `network/` folders. **Status:** the summer.games export is in Summer's editor.

How to install
mdr add summerengine/summer/multiplayer-publish@sha256:4164271a7ac5f239The line at the top of this page pins the label git:20261012.3857d96, 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.
