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
## When to use Use this whenever a change touches `store-libsql`'s on-disk schema: a new/altered table or column, an index change, a DiskANN/FTS5 rebuild, or a change that invalidates existing chunks/embeddings. Full design background: [docs/migrations.md](../../../docs/migrations.md), [specs/02-domain-model.md](../../../specs/02-domain-model.md) §9, [specs/05-surfaces.md](../../../specs/05-surfaces.md) §2.1. **Never touch `store-libsql/src/migrations/baseline.rs`.** It is a frozen, byte-for-byte copy of the v4 DDL, used only as an "old database" fixture source for tests. New schema changes are chain entries — never edits to that file. ## Checklist 1. **Pick the next version.** `store_libsql::head_version_current()` (re-exported; internally `chain::head_version(&chain::migrations())`) is the current head. Your migration's `version` is `head_version_current() + 1`. The chain must stay contiguous from `chain::BASELINE_VERSION + 1` (`= 5`) — `chain::validate_chain` enforces this in CI. **Racing another branch:** if another in-flight branch also adds a migration against the same …

How to install
mdr add dokterbob/localdb/add-migration@sha256:36f1727d5bbab3e9The line at the top of this page pins the label git:20260906.60120c5, 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.
