Use when versioning or converting serialized player save files, profiles, checkpoints, or persistence payloads across recognized save-format versions with fixture compatibility and rollback.
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
# Save Data Schema Migration ## Overview Plan and test player-save migrations through an explicit version chain while preserving the original payload and refusing unknown or newer versions. ## When to use Use for save field renames, defaults, removals, version upgrades, backward compatibility, import migrations, or player-data format changes. ## When NOT to use Do not use for database schema migration, arbitrary config edits, or direct production player-save rewrites without a project runbook. ## Required inputs and context discovery Require current and target versions, migration chain, save authority, fixture set, backup scope, rollback method, compatibility window, reviewer, human approval, privacy constraints, and validation checks. ## Safety and risk level High-risk. Unknown versions, incomplete chains, missing backup, missing rollback, missing reviewer, live player data, or missing approval means BLOCKED. ## Workflow 1. Identify save authority, current version, target version, and supported compatibility range. Completion criterion: unknown or newer versions are BLOCKED. 2. Review each one-version migration step for rename, default, removal, and data loss. …

How to install
mdr add hoatv2211/gamestudio-codexkit/save-data-schema-migration@sha256:7be862f3883dbc92The line at the top of this page pins the label v0.1.0, 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.
