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

# common-meta — Agent & Contributor Guide

Navigation map for `src/common/meta`. Repo-wide invariants:
[`.agents/architecture-invariants.md`](../../../.agents/architecture-invariants.md).

`common-meta` contains shared metadata keys and values, KV backends, caches,
and durable DDL procedures. Metasrv process and service wiring live in
`src/meta-srv`.

## Module map

| Area | Path | Entry point |
| --- | --- | --- |
| Affinity | `src/common/meta/src/affinity.rs` | Requirements, reference resolution, node matching, and allocation-context provider |
| Metadata model | `src/common/meta/src/key.rs`, `src/common/meta/src/key/` | Typed keys, values, and `TableMetadataManager` |
| KV storage | `src/common/meta/src/kv_backend.rs`, `src/common/meta/src/kv_backend/` | `KvBackend`, transactions, memory/etcd/RDS backends |
| DDL procedures | `src/common/meta/src/ddl.rs`, `src/common/meta/src/ddl/`, `src/common/meta/src/ddl_manager.rs` | Durable DDL state machines and task dispatch |
| Caches | `src/common/meta/src/cache.rs`, `src/common/meta/src/cache/`, `src/common/meta/src/cache_invalidator.rs` | Metadata caches and invalidation |

How to install

The exact contents, by fingerprint
mdr add greptimeteam/greptimedb/src/common/meta/AGENTS.md@sha256:4c5812a79fd3a471

The line at the top of this page pins the label git:20261015.cbfbad4, 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.
