DEVIATIONS
Changes made by Hanzo AI, Inc. relative to upstream Casibase:

- Repackaged from github.com/casbin/casbase (later Casibase) to the Go module
  github.com/hanzoai/ai; product rebranded to Hanzo AI across README, docs, and UI.
- Identity and authentication replaced with Hanzo IAM (github.com/hanzoai/iam;
  web SDK @hanzo/iam-js-sdk).
- Web framework forked to github.com/hanzoai/beego.
- Datastore dropped mattn/go-sqlite3 and standardized on github.com/hanzo-ds/go with
  github.com/hanzoai/sqlite.
- Cryptography and runtime primitives sourced from the Lux stack
  (github.com/luxfi/crypto, luxfi/geth, luxfi/log, luxfi/metric, luxfi/zap, luxfi/pq).
- Rebuilt as an LLM control plane: native Go routing for 66+ models over an
  OpenAI-compatible surface (/v1/chat/completions, /v1/models), with provider
  integrations for Anthropic, OpenAI, Cohere, Mistral, AWS Bedrock, Azure,
  Baidu Qianfan, and Alibaba DashScope.
- Added the Zen model family with Anthropic reasoning-vocabulary round-tripping.
- Added a fine-tune broker for HuggingFace-native LoRA/QLoRA training and deploy
  (/v1/finetune/*).
- Provider secrets resolved through Hanzo KMS, scoped per org; per-request usage
  metered to Hanzo IAM with org-subject billing.
- Mounts as the "ai" subsystem inside the hanzoai/cloud unified binary
  (github.com/hanzoai/cloud).
