+implement lib/hero/heroserver
+
+see aiprompts/v_core/veb for how servers are done and also see examples/hero/herorpc/herorpc_example.vsh how we start the server  in an example
+and the implementation of the example of how webserver is see lib/schemas/openrpc/controller_http.v
+
+specs for the heroserver
+
+- a factory (without globals) creates a server, based on chosen port
+- the server does basic authentication and has 
+    - register method: pubkey
+    - authreq: pubkey, it returns a unique key (hashed md5 of pubkey + something random). (is a request for authentication)
+    - auth: the user who wants access signs the unique key from authreq with , and sends the signature to the server, who then knows for sure I know this user, we return as sessionkey
+- all consequent requests need to use this sessionkey, so the server knows who is doing the requests
+- the server serves the openrpc api behind api/$handlertype/... the $handlertype is per handler type, so we can register more than 1 openrpc hander
+- the server serves an html endpoint for doc/$handlertype/
+
+
+for the doc (html endpoint)
+
+- use bootstrap from cdn
+  - https://cdn.jsdelivr.net/npm/bootstrap@5.3.3/dist/css/bootstrap.min.css
+  - https://cdn.jsdelivr.net/npm/bootstrap@5.3.3/dist/js/bootstrap.min.js
+  - https://cdn.jsdelivr.net/npm/bootstrap@5.3.3/dist/js/bootstrap.bundle.min.js
+- create an html template in lib/hero/heroserver/template/doc.md (template for v language)
+   - the template uses the openrpc spec obj comes from lib/schemas/openrpc and  lib/schemas/jsonrpc for the schema's
+   - so first fo the spec decode to the object from schemas/openrpc then use this obj to populate the template
+   - in the template make a header 1 for each rootobject e.g. calendar, then dense show the methods with directly in the method a dense representation of the params and return
+   - each object e.g. pub fn (self Comment) description(methodname string) string { has a description and pub fn (self Comment) example(methodname string) (string, string) wich returns description per method, if not filled in then its for the full rootobject, and also example, make sure to use those in the template for the documentation
+    - the template is markdown, we will have to use a .md to .html conversion (best to do in browser itself) and get .md from the webserver directly and convert
+    - the purpose is to have a very nice documentation done per object so we know what the object does, and how to use it
+
+make clear instructions what code needs to be written and which steps are needed
+we are in architecture mode

+# @{handler_type} API Documentation
+
+@{spec.info.description}
+
+**Version:** @{spec.info.version}
+
+## Overview
+
+This documentation provides details about the @{handler_type} API endpoints and their usage.
+
+@{methods}
+
+## Authentication
+
+All API requests require a valid session key obtained through the authentication flow:
+
+1. **Register**: Submit your public key to register
+2. **Request Challenge**: Get an authentication challenge  
+3. **Authenticate**: Sign the challenge and submit for session key
+4. **Use Session**: Include session key in subsequent API requests
+
+## Error Handling
+
+The API uses standard JSON-RPC 2.0 error codes:
+
+- `-32700`: Parse error
+- `-32600`: Invalid Request  
+- `-32601`: Method not found
+- `-32602`: Invalid params
+- `-32603`: Internal error
