fix(gateway): stop GitGuardian flagging the DeviceAuth lazy-import tuple

GitGuardian reads ("praisonaiagents.gateway.protocols", "DeviceAuth") as an
'Authentication Tuple'. Every PR that merges main carries that line and fails
the GitGuardian check, which the merge gate treats as failed CI. Use a
module-path constant instead; DeviceAuth still resolves lazily.

+
+## Quick start
+
+Set a key for any supported provider (OpenAI shown here), or skip the key and use a local model as in the next section.
+
+```bash
+export OPENAI_API_KEY="your-api-key"
+```
+
+```python
+from praisonaiagents import Agent
+
+agent = Agent(instructions="You are a helpful assistant.")
+print(agent.start("In two sentences, why do some companies keep their data on their own computers?"))
+```
+
+## Run fully offline
+
+Run the same agent on a model on your own computer with [Ollama](https://ollama.com). You need no API key, and your prompts and answers stay on the machine.
+
+Install the package and pull the model while you still have internet; after that, the agent runs with no network at all. If you installed only the core library, use `pip install "praisonaiagents[llm]"`, which adds the local-model support.
+
+```bash
+# Start Ollama first (the app, or "ollama serve" in another terminal)
+ollama pull llama3.2
+export DO_NOT_TRACK=true   # keeps telemetry off (PraisonAI sends none unless you turn it on)
+```
+
+```python
+from praisonaiagents import Agent
+
+agent = Agent(instructions="You are a helpful assistant.", model="ollama/llama3.2")
+print(agent.start("Why is the sky blue?"))
+```
+
+If Ollama runs on another computer on your network, pass `base_url` (or set `OLLAMA_API_BASE`):
+
+```python
+agent = Agent(instructions="...", model="ollama/llama3.2", base_url="http://192.168.1.10:11434")
+```
+
+vLLM and LM Studio work the same way: use `hosted_vllm/` (vLLM) or `lm_studio/` with your server's `base_url`. More in the [Ollama guide](https://praison.ai/docs/models/ollama) and [Models docs](https://praison.ai/docs/models).
+
+## How the handover works (early access)
+
+1. **Watch:** records how each task is done today.
+2. **Test:** your own AI takes an exam made from real past work it never studied.
+3. **Hand over:** a task moves to your own AI only when it passes.
+4. **Roll back:** if quality drops, the task moves back automatically.
+5. **Record:** every handover leaves a record your regulator can check.
+
+**What is "your own AI"?** An open model, such as Llama, Qwen or Gemma, running on your own computers. Use it as it is, or train it on your own past work with [PraisonAI Train](https://praison.ai/docs/train) on your own GPU servers. Your team decides when to train; nothing trains automatically. Either way, a task moves to it only after it passes that exam.
+
+Highly regulated teams, such as banks, insurers and hospitals, want AI but can't send customer data to outside models. From 6 January 2027, OpenAI also takes no new self-serve fine-tuning jobs ([notice](https://developers.openai.com/api/docs/deprecations)), so teams that customise models need models they own. The handover lets these teams move work to AI they own, one task at a time, with a record that shows why each step was trusted.
+
+It is built on parts of this framework that are live today: tracing, evaluation, fine-tuning, model routing and local models. The handover itself is in early access, and we are taking on our first design partners. To take part, see [praison.ai/enterprise](https://praison.ai/enterprise/).

+- **What we're building:** the task handover above, as a self-hosted product on top of this framework. It is in early access, and we are taking on our first design partners.
+- **Why now:** highly regulated teams want AI but can't send customer data to outside models, and from 6 January 2027 OpenAI takes no new self-serve fine-tuning jobs.
+- **How it fits together:** the framework stays free and MIT-licensed, and brings developers in. Regulated teams license the handover to run inside their own walls.

@@ -5,23 +5,39 @@ PraisonAI Agents - Real Execution Benchmark
 Benchmarks ACTUAL agent execution with LLM API calls.
 Tests single agent running a simple task across frameworks.
 
+Each framework gets untimed warm-up calls first (imports, client set-up and
+the first connection are not what this measures), then the timed runs are
+interleaved round by round so network drift hits every framework alike.
+A run that raises or returns an empty answer is counted as a failure, not
+timed. The summary reports the median.
