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

# `mirrord-protocol`

## Backwards Compatibility

The protocol defines the messages that layer, intproxy, agent, and operator send to each other. These components ship
independently, so we must make sure that they are able to talk to each other even when running mismatched versions. The
wire format is generated by the Rust types layouts through `bincode`, so the declarations in this crate _are_ the wire
format.

**Safe changes**:

- Renaming types, fields, or variants (bincode doesn't use names).
- Changing a field type only if the bincode representation stays the same.
- Adding a new enum variant **at the end**, gated by a negotiated protocol version.
- Code changes that don't affect the wire representation.

**Breaking changes**:

- Adding a field to a struct.
- Changing `T` to/from `Option<T>`.
- Reordering fields in a struct.
- Reordering enum variants.

Version checks are defined as `LazyLock<VersionReq>` constants near the types they protect. Consumers use
`SwitchProtocolVersion` to negotiate.

## CI and Versioning Rules

- This crate is versioned **independently** from the rest of the workspace.

How to install

The exact contents, by fingerprint
mdr add metalbear-co/mirrord/mirrord/protocol/AGENTS.md@sha256:67b9a3a6dd230891

The line at the top of this page pins the label git:20261028.be6a47a, 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.
