Release v4.7.24

* fix: confine gateway operators to specific agents via auth_scopes (fixes #6253)

A token's auth_scopes entry may now be {scopes: [...], agents: [...]}.
GatewayConfig.resolve_agents(token) returns the confinement (None =
every agent, so existing token -> [scopes] policies are unchanged). The
bot gateway enforces it where a WS client binds to an agent (hello/join,
including session resume via join) and withholds broadcast events
sourced from agents outside the grant.

* fix: apply YAML operator policy at gateway startup; fail closed on unknown grant keys

- start_with_config now stamps gateway.auth_scopes / gateway.auth.tokens onto
  self.config, so YAML agent confinement (and scopes) actually take effect.
- Grant mappings reject unknown keys (core parser + typed OperatorGrantSchema),
  so a typo like 'agnts' cannot silently remove a confinement.
- Document that HTTP approval endpoints are not yet agent-filtered (#5151).

* fix: expand ${VAR} auth_scopes keys at gateway startup; tolerate older core

- start_with_config(): load_gateway_config resolves ${VAR} in values only, so
  auth_scopes keys stayed literal placeholders. Expand them, drop keys that
  resolve to empty, and refuse to start if a declared policy ends up empty
  (an empty policy means "no policy" and would fail open).
- Guard the private _parse_auth_scopes import and the resolve_agents call so
  an older praisonaiagents keeps pre-#6253 behaviour instead of ImportError.
- Tests for placeholder expansion, all-unset fail-closed (both YAML forms)
  and the older-core fallback.

+
+## 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.

 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.

+Session manifest: one durable record per ``session_id`` holding a write-ahead
+"run in flight" marker (Issue #6248), so a later launch can tell that a run on
+this session died before reaching a terminal outcome.
+
+Usage::
+
+    from praisonaiagents.session.manifest import FileSessionManifest
+
+    manifest = FileSessionManifest()
+    entry = manifest.begin_run("my-session", "run-42", run_input="fix the bug")

+
+    # Next launch:
+    stale = manifest.interrupted("my-session")   # entry or None
+
+The run input itself is never written to disk: only a SHA-256 digest of it
+is kept (``run_digest``), enough to recognise a retry of the same task without
+storing prompts (which may contain secrets) in plaintext.
+
+A run that keeps dying is bounded by ``max_attempts``: once the budget is
+spent, ``begin_run`` logs the stale run as abandoned and restarts the attempt
+counter instead of counting it up forever.
