# `mix rma.sync_agentcore_model`
[🔗](https://github.com/cash-mckeeman/req_managed_agents/blob/v0.13.0/req_managed_agents/lib/mix/tasks/rma.sync_agentcore_model.ex#L1)

Maintainer task: mirrors the `bedrock-agentcore` and `bedrock-agentcore-control`
botocore `service-2.json` models from `boto/botocore` into
`$RMA_CORPUS_DIR/agentcore/model/`, and pins the upstream commit plus
per-file SHA256 in `$RMA_CORPUS_DIR/agentcore/manifest.json`.

Not shipped in the hex package (`lib/mix` is excluded from `package.files`)
and not exercised by CI — only `changeset/2` is unit-tested. Requires
`RMA_CORPUS_DIR` (the private conformance corpus checkout):

    RMA_CORPUS_DIR=/path/to/corpus mix rma.sync_agentcore_model

Exit codes: 0 = model already up to date; 2 = model was updated (drift
signal for a maintainer CI job); 1 = task failure. TLS is verified against
`:public_key.cacerts_get/0`. Set `GITHUB_TOKEN` for API rate-limit headroom.

# `changeset`

```elixir
@spec changeset(%{optional(String.t()) => binary()}, map()) :: %{
  added: [String.t()],
  changed: [String.t()],
  removed: [String.t()]
}
```

Compares fetched upstream content against a locally recorded manifest and
reports which paths are new, changed (SHA256 mismatch), or gone. Pure —
does no I/O, so it's unit-testable without network access.
