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
# Colyseus Multiplayer ## Philosophy - Treat every client as untrusted: the server decides, the client only asks. - Validate before you mutate: parse the payload, check ownership and rules, then change state. - Plan for dropped connections as the normal case, not the exception. - Keep synchronised state in Schema and keep matchmaking metadata honest about the room. ## When to Use - Building server-authoritative multiplayer game backends with Colyseus 0.17+. - Defining rooms, Schema state and lifecycle hooks (`onCreate`, `onJoin`, `onLeave`, `onDrop`). - Writing message handlers that must validate client payloads and resist cheating. - Configuring matchmaking metadata, authentication or reconnection policy. ## When Not to Use - Peer-to-peer networking, where there is no authoritative server. - Single-player game architecture with no networked state. - Client-side rendering or prediction code that never touches room logic. ## Core Principles 1. Server is authoritative for all game state. 2. Room state changes must be validated before applying. 3. Reconnection and drop handling must be explicit. 4. Matchmaking metadata must reflect real room capability. …

How to install
mdr add pantheon-org/tekhne/colyseus-multiplayer@sha256:4036abdde47ebe20The line at the top of this page pins the label git:20261007.83cf275, 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.
