+1. Generate a keypair locally (public key is safe to share)
+	- `python tools/gen_auth.py --nonce init`
+	- Copy PUBLIC_HEX (compressed 33-byte hex, 66 chars). PRIVATE_HEX is your secret—keep it safe.
+
+- Example output:
+```
+PRIVATE_HEX=5d38d57c83ef1845032fdee1c954958b66912218744ea31d0bc61a07115b6b93

+```
+
+2. Fetch a real nonce from the server
+	- In hero-openrpc-client menu, choose fetch_nonce
+	- Paste PUBLIC_HEX when prompted
+	- Copy the returned nonce string (the exact ASCII hex string)
+
+- Example output:
+```

+//! jsonrpsee supports two kinds of middlewares `http_middleware` and `rpc_middleware`.
+//!
+//! This example demonstrates how to use the `rpc_middleware` which applies for each
+//! JSON-RPC method call and batch requests may call the middleware more than once.
+//!
+//! A typical use-case for this is to implement rate-limiting based on the actual
+//! number of JSON-RPC methods calls and a request could potentially be made
+//! by HTTP or WebSocket which this middleware is agnostic to.
+//!
+//! Contrary the HTTP middleware does only apply per HTTP request and
+//! may be handy in some scenarios such CORS but if you want to access
+//! to the actual JSON-RPC details this is the middleware to use.
+//!
+//! This example enables the same middleware for both the server and client which
+//! can be confusing when one runs this but it is just to demonstrate the API.
+//!
+//! That the middleware is applied to the server and client in the same way.

+# Object Storage and Indexing System (OSIS) Actor
+
+The OSIS Actor is responsible for storing and indexing objects in the system. It implements the actor interface to process jobs in a **blocking, synchronized manner**.
+
+## Job Processing Behavior
+
+The OSISActor processes jobs sequentially with the following characteristics:
+
+- **Blocking Processing**: Each job is processed completely before the next job begins
+- **Synchronized Execution**: Jobs are executed one at a time in the order they are received
+- **No Concurrency**: Unlike async actors, OSIS ensures no parallel job execution
+- **Deterministic Order**: Job completion follows the exact order of job submission
+
+This design ensures data consistency and prevents race conditions when performing storage and indexing operations.
+
+## Usage
+
+```rust
+use actor_osis::{OSISActor, spawn_osis_actor};
+
+// Create an OSIS actor with builder pattern
+let actor = OSISActor::builder()
+    .db_path("/path/to/database")
+    .redis_url("redis://localhost:6379")
+    .build()
+    .expect("Failed to build OSISActor");
+
+// Or spawn directly with convenience function
+let handle = spawn_osis_actor(
+    "/path/to/database".to_string(),
+    "redis://localhost:6379".to_string(),
+    shutdown_rx,
+);
+```
+
+## Actor Properties
+
+- **Actor ID**: `"osis"` (constant)
+- **Actor Type**: `"OSIS"`
+- **Processing Model**: Sequential, blocking
+- **Script Engine**: Rhai with OSIS-specific DSL extensions
+## Canonical Redis queues and verification
+
+The project uses canonical dispatch queues per script type. For OSIS, the work queue is:
+- hero:q:work:type:osis
+
+Consumer behavior:
+- The in-repo actor derives ScriptType=OSIS from its actor_id containing "osis" and BLPOPs hero:q:work:type:osis.
+- This repo’s OSIS actor has been updated so its actor_id is "osis", ensuring it consumes the canonical queue.
+
+Quick verification (redis-cli):
+- List work queues:
+  - KEYS hero:q:work:type:*
+- Check OSIS queue length:
+  - LLEN hero:q:work:type:osis
+- Inspect a specific job (replace {job_id} with the printed id):
+  - HGET hero:job:{job_id} status
+  - HGET hero:job:{job_id} output
+
+Run options:
+- Option A: Run the example which spawns the OSIS actor and dispatches jobs to the canonical queue.
+  1) Start Redis (if not already): redis-server
+  2) In this repo:
+     - cargo run --example actor
+  3) Observe the console: job IDs will be printed as they are created and dispatched.
+  4) In a separate terminal, verify with redis-cli:
+     - LLEN hero:q:work:type:osis (will briefly increment, then return to 0 as the actor consumes)
+     - HGET hero:job:{job_id} status (should transition to started then finished)
+     - HGET hero:job:{job_id} output (should contain the script result)
+
+- Option B: Run the standalone actor binary and dispatch from another process that pushes to the canonical type queue.
+  1) Start the actor:
+     - cargo run --bin actor_osis
+  2) From any producer, LPUSH hero:q:work:type:osis {job_id} after persisting the job hash hero:job:{job_id}.
+  3) Use the same redis-cli checks above to confirm consumption and completion.
+
+Notes:
+- Hash-only result model is the default. The job result is written to hero:job:{job_id}.output and status=finished.
+- Reply queues (hero:q:reply:{job_id}) are optional and not required for OSIS to function.

+//! # Rhailib Domain-Specific Language (DSL) Engine
+//!
+//! This module provides a comprehensive Domain-Specific Language implementation for the Rhai
+//! scripting engine, exposing business domain models and operations through a fluent,
+//! chainable API.
+//!
+//! ## Overview
+//!
+//! The DSL is organized into business domain modules, each providing Rhai-compatible
+//! functions for creating, manipulating, and persisting domain entities. All operations
+//! include proper authorization checks and type safety.
+//!
+//! ## Available Domains
+//!
+//! - **Business Operations** (`biz`): Companies, products, sales, shareholders
+//! - **Financial Models** (`finance`): Accounts, assets, marketplace operations
+//! - **Content Management** (`library`): Collections, images, PDFs, books, slideshows
+//! - **Workflow Management** (`flow`): Flows, steps, signature requirements
+//! - **Community Management** (`circle`): Circles, themes, membership
+//! - **Contact Management** (`contact`): Contact information and relationships
+//! - **Access Control** (`access`): Security and permissions
+//! - **Time Management** (`calendar`): Calendar and scheduling
+//! - **Core Utilities** (`core`): Comments and fundamental operations
+//! - **Generic Objects** (`object`): Generic object manipulation
+//!
+//! ## Usage Example
+//!
+//! ```rust
+//! use rhai::Engine;
+//! use crate::engine::register_dsl_modules;
+//!
+//! let mut engine = Engine::new();
+//! register_dsl_modules(&mut engine);
+//!
+//! // Now the engine can execute scripts like:
+//! // let company = new_company().name("Acme Corp").email("contact@acme.com");
+//! // let saved = save_company(company);
+//! ```

+///
+/// * `engine` - A mutable reference to the Rhai engine to register modules with

+/// "#).unwrap();
+/// assert_eq!(result, "Test Corp");

+///
+/// This function registers the following domain modules:
+/// - Access control functions
+/// - Business operation functions (companies, products, sales, shareholders)
+/// - Calendar and scheduling functions
+/// - Circle and community management functions
+/// - Company management functions
+/// - Contact management functions
+/// - Core utility functions
+/// - Financial operation functions (accounts, assets, marketplace)
+/// - Workflow management functions (flows, steps, signatures)
+/// - Library and content management functions
+/// - Generic object manipulation functions (custom implementation)

+Generate secp256k1 keypair and sign a nonce in the exact format the server expects.
+
+Install dependencies once:

+
+Usage examples:
+  # Generate a new keypair and sign a nonce (prints PRIVATE_HEX, PUBLIC_HEX, SIGNATURE_HEX)
+  python tools/gen_auth.py --nonce "PASTE_NONCE_FROM_fetch_nonce"
+
+  # Sign with an existing private key (64 hex chars)

+
+  # Output JSON instead of key=value lines
+  python tools/gen_auth.py --nonce "PASTE_NONCE" --json
+
+Notes:
+- Public key is compressed (33 bytes) hex, starting with 02/03 (66 hex chars total).
+- Signature is compact ECDSA (r||s) 64 bytes (128 hex chars).
+- The nonce should be the exact ASCII string returned by fetch_nonce().
+- The message signed is sha256(nonce_ascii) to match client/server behavior:
+  - [rust.AuthHelper::sign_message()](interfaces/openrpc/client/src/auth.rs:55)

+Non-destructive JSON-RPC smoke tests against the OpenRPC server.

+What it tests (non-destructive):
+- fetch_nonce(pubkey)  -> returns a nonce string from the server auth manager
+- whoami()             -> returns a JSON string with basic server info
+- list_jobs()          -> returns job IDs only (no mutation)
+- get_job_status(id)   -> reads status (for up to --limit items)
+- get_job_output(id)   -> reads output (for up to --limit items)
+- get_job_logs(id)     -> reads logs (for up to --limit items)
+
+Notes:
+- If you don't pass --pubkey, this script will generate a random secp256k1 keypair
