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

# Schema Migrations

- Use `SchemaManager`/SeaQuery builders and migration-local `DeriveIden`/`Alias`.
  Never depend on `pioneer-entity`, including Entity for existing tables.
- Raw SQL requires a specific operation missing from the installed builders,
  such as trigger DDL. Document that gap; historical SQL is not blanket precedent.
- Change applied or released schema through a new migration registered in
  [Migrator](src/lib.rs). Preserve historical names, order and semantics.
  An unpublished, unapplied draft may be amended instead of adding another file.
- `up` installs the new schema; `down` restores the previous schema, removing
  dependent objects in the appropriate order. Do not promise recovery of deleted data.
- Justify each new table/index and its installation cost on existing databases,
  including scans and index construction over large tables.
- Keep schema installation limited to schema changes and necessary seed rows.
  Heavy historical backfill belongs to the existing
  [Gateway data-migration mechanism](../gateway/src/database/AGENTS.md).
- After schema changes, follow [Entity generation](../entity/AGENTS.md).

How to install

The exact contents, by fingerprint

mdr add pioneerdotai/pioneer/crates/migration/AGENTS.md@sha256:e71106d3dca981fa

The line at the top of this page pins the label git:20261026.4f21256, 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.
