About ARI
Project meta — the policies and references that govern the project as a whole, rather than any single feature.
Policies & references
| Document | What it covers |
|---|---|

| Compatibility & support | Supported Python, the Letta memory backend, and LLM backends. |
| Contributing | Software-engineering discipline, the layered architecture, the public-API rule, and the deprecation process. |
| Changelog | Per-release notes (Added / Changed / Fixed / Deprecated / Removed / Security). |
| Security policy | How to report a vulnerability and which versions receive fixes. |
Licensing
ARI does not ship a single repository-level licence file; licensing is per published artifact. When you publish an Experiment Artifact Repository (EAR), its ear/publish.yaml declares an SPDX license (MIT / Apache-2.0 / BSD-3-Clause / GPL-3.0 / CC-BY-4.0) and generate_ear emits the matching LICENSE file into the bundle. See Configuration → EAR Curation.
