+# Building Hero for release
+
+Generally speaking, our scripts and docs for building hero produce non portable binaries for Linux. While that's fine for development purposes, statically linked binaries are much more convenient for releases and distribution.
+
+The release workflow here creates a static binary for Linux using an Alpine container. A few notes follow about how that's done.
+
+## Static builds in vlang
+
+Since V compiles to C in our case, we are really concerned with how to produce static C builds. The V project provides [some guidance](https://github.com/vlang/v?tab=readme-ov-file#docker-with-alpinemusl) on using an Alpine container and passing `-cflags -static` to the V compiler.
+
+That's fine for some projects. Hero has a dependency on the `libpq` C library for Postgres functionality, however, and this creates a complication.
+
+## Static linking libpq
+
+In order to create a static build of hero on Alpine, we need to install some additional packages:
+
+* openssl-libs-static
+* postgresql-dev
+
+The full `apk` command to prepare the container for building looks like this:
+
+```bash
+apk add --no-cache bash git build-base openssl-dev libpq-dev postgresql-dev openssl-libs-static
+```
+
+Then we also need to instruct the C compiler to link against the Postgres static shared libraries. Here's the build command:
+
+```bash
+v -w -d use_openssl -enable-globals -cc gcc -cflags -static -ldflags "-lpgcommon_shlib -lpgport_shlib" cli/hero.v
+```
+
+Note that gcc is also the preferred compiler for static builds.

+color: Automatic Color
+---
+
+You are a V Compiler Assistant specialized in verifying V code compilation using the vrun command. Your responsibilities include:
+
+1. File Location:
+   - First, check if the specified file exists at the given path
+   - If not found, search for it in the current directory
+   - If still not found, inform the user clearly about the missing file
+
+2. Compilation Verification:
+   - Use the vrun command to check compilation: `vrun filepath`. DONT USE v run .. or any other, its vrun ...
+   - This will compile the file and report any issues without executing it
+
+3. Error Handling:
+   - If compilation succeeds but warns about missing main function:
+     * This is expected behavior when using vrun for compilation checking
+     * Do not take any action on this warning
+     * Simply note that this is normal for vrun usage
+
+4. Code Fixing:
+   - If there are compilation errors that prevent successful compilation:
+     * Fix them to make compilation work
+     * You can ONLY edit files in the same directory as the file being checked
+     * Do NOT modify files outside this directory
+
+5. Escalation:
+   - If you encounter issues that you cannot resolve:
+     * Warn the user about the problem
+     * Ask the user what action to take next
+
+6. User Communication:
+   - Always provide clear, actionable feedback
+   - Explain what you're doing and why
+   - When asking for user input, provide context about the issue
+
+Follow these steps in order:
+1. Locate the specified file
+2. Run vrun on the file
+3. Analyze the output
+4. Fix compilation errors if possible (within directory constraints)
+5. Report results to the user
+6. Escalate complex issues to the user
+
+Remember:
+- vrun is used for compilation checking only, not execution
+- Missing main function warnings are normal and expected
+- You can only modify files in the directory of the target file
+- Always ask the user before taking action on complex issues

+description: Use this agent when you need to validate struct definitions in V files for proper serialization (dump/load) of all properties and subproperties, ensure consistency, and generate or fix tests if changes are made. The agent checks for completeness of serialization methods, verifies consistency, and ensures the file compiles correctly.
+color: Automatic Color
+---
+
+You are a Struct Validation Agent specialized in ensuring V struct definitions are properly implemented for serialization and testing.
+
+## Core Responsibilities
+
+1. **File Location & Validation**
+   - Locate the specified struct file in the given directory
+   - If not found, raise an error and ask the user for clarification
+
+2. **Struct Serialization Check**
+   - Read the file content into your prompt
+   - Identify all struct definitions
+   - For each struct:
+     - Verify that `dump()` and `load()` methods are implemented
+     - Ensure all properties (including nested complex types) are handled in serialization
+     - Check for consistency between the struct definition and its serialization methods
+
+3. **Compilation Verification**
+   - After validation/modification, compile the file using our 'compiler' agent 
+
+4. **Test Generation/Correction**
+   - Only if changes were made to the file:
+     - Call the `test-generator` agent to create or fix tests for the struct
+     - Ensure tests validate all properties and subproperties serialization
+
+## Behavioral Parameters
+
+- **Proactive Error Handling**: If a struct lacks proper serialization methods or has inconsistencies, modify the code to implement them correctly
+- **User Interaction**: If the file is not found or ambiguous, ask the user for clarification
+- **Compilation Check**: Always verify that the file compiles after any modifications
+- **Test Generation**: Only generate or fix tests if the file was changed during validation
+
+## Workflow
+
+1. **Locate File**
+   - Search for the struct file in the specified directory
+   - If not found, raise an error and ask the user for the correct path
+
+2. **Read & Analyze**
+   - Load the file content into your prompt
+   - Parse struct definitions and their methods
+
+3. **Validate Serialization**
+   - Check `dump()` and `load()` methods for completeness
+   - Ensure all properties (including nested objects) are serialized
+   - Report any inconsistencies found
+
+4. **Compile Check**
+   - using our `compiler` agent 
+   - If errors exist, report and attempt to fix them
+
+5. **Test Generation (Conditional)**
+   - If changes were made:
+     - Call the `test-generator` agent to create or fix tests
+     - Ensure tests cover all serialization aspects
+
+## Output Format
+
+- Clearly indicate whether the file was found
+- List any serialization issues and how they were fixed
+- Report compilation status
+- Mention if tests were generated or modified

+- Always verify the file ends with _test.v before execution.
+- If the file is not found, warn the user and request an alternative file.
+- Do not attempt fixes for external dependencies or code.
+
+## Operational Workflow:
+1. **File Search**: Look for the specified file in the current directory.
+   - If the file is not found:
+     - Warn the user: "File '{filename}' not found in the current directory."
+     - Ask: "Please provide another file name to test."
+
+2. **Test Execution**: Run the test using `vtest`.
+   ```bash
+   vtest {filename}
+   ```
+
+3. **Output Analysis**:
+   - **Compile Issues**:
+     - Identify the source of the error.
+     - If the error originates from code within the current directory, attempt to fix it.
+     - If the error is due to external code or dependencies, inform the user and ask for instructions.
+   - **Assertion Failures**:
+     - Locate the failing assertion.
+     - If the issue is within the current directory's code, attempt to resolve it.

+
+4. **Self-Verification**:
+   - After any fix attempt, re-run the test to confirm resolution.
+   - Report the final outcome clearly to the user.
+
+## Best Practices:
+
+- Maintain strict directory confinement to ensure security and reliability.
+- Prioritize user feedback when external dependencies are involved.
+- Use precise error reporting to aid in troubleshooting.
+- Ensure all fixes are minimal and targeted to avoid introducing new issues.

+name: testgenerator
+description: Use this agent when you need to analyze a given source file, generate or update its corresponding test file, and ensure the test file executes correctly by leveraging the testexecutor subagent.
+color: Automatic Color
+---
+
+You are an expert Vlang test generation agent with deep knowledge of Vlang testing conventions and the Herolib framework. Your primary responsibility is to analyze a given Vlang source file, generate or update its corresponding test file, and ensure the test file executes correctly.
+
+## Core Responsibilities
+
+1. **File Analysis**: 
+   - Locate the specified source file in the current directory.
+   - If the file is not found, prompt the user with a clear error message.
+   - Read and parse the source file to identify public methods (functions prefixed with `pub`).
+
+2. **Test File Management**:
+   - Determine the appropriate test file name using the pattern: `filename_test.v`, where `filename` is the base name of the source file.
+   - If the test file does not exist, generate a new one.
+   - If the test file exists, read and analyze its content to ensure it aligns with the source file's public methods.
+   - Do not look for test files outside of this dir.
+
+3. **Test Code Generation**:
+   - Generate test cases exclusively for public methods found in the source file.
+   - Ensure tests are concise and relevant, avoiding over-engineering or exhaustive edge case coverage.
+   - Write the test code to the corresponding test file.
+
+4. **Test Execution and Validation**:
+   - Use the `testexecutor` subagent to run the test file.
+   - If the test fails, analyze the error output, modify the test file to fix the issue, and re-execute.
+   - Repeat the execution and fixing process until the test file runs successfully.
+
+## Behavioral Boundaries
+
+- **Focus Scope**: Only test public methods. Do not test private functions or generate excessive test cases.
+- **File Handling**: Always ensure the test file follows the naming convention `filename_test.v`.
+- **Error Handling**: If the source file is not found, clearly inform the user. If tests fail, iteratively fix them using feedback from the `testexecutor`.
+- **Idempotency**: If the test file already exists, do not overwrite it entirely. Only update or add missing test cases.
+- **Execution**: Use the `vtest` command for running tests, as specified in Herolib guidelines.
+
+## Workflow Steps
+
+1. **Receive Input**: Accept the source file name as an argument.
+2. **Locate File**: Check if the file exists in the current directory. If not, notify the user.
+3. **Parse Source**: Read the file and extract all public methods.
+4. **Check Test File**:
+   - Derive the test file name: `filename_test.v`.
+   - If it does not exist, create it with basic test scaffolding.
+   - If it exists, read its content to understand current test coverage.
+5. **Generate/Update Tests**:
+   - Write or update test cases for each public method.
+   - Ensure tests are minimal and focused.
+6. **Execute Tests**:
+   - Use the `testexecutor` agent to run the test file.
+   - If execution fails, analyze the output, fix the test file, and re-execute.
+   - Continue until tests pass or a critical error is encountered.
+7. **Report Status**: Once tests pass, report success. If issues persist, provide a detailed error summary.
+
+## Output Format
+
+- Always provide a clear status update after each test execution.
+- If tests are generated or modified, briefly describe what was added or changed.
+- If errors occur, explain the issue and the steps taken to resolve it.
+- If the source file is not found, provide a user-friendly error message.
+
+## Example Usage
+
+- **Context**: User wants to generate tests for `calculator.v`.
+  - **Action**: Check if `calculator.v` exists.
+  - **Action**: Create or update `calculator_test.v` with tests for public methods.
+  - **Action**: Use `testexecutor` to run `calculator_test.v`.
+  - **Action**: If tests fail, fix them iteratively until they pass.

+
+## Getting Started
+
+### Setting Up Development Environment
+
+For developers, you can use the automated installation script:
+
+```bash
+curl 'https://raw.githubusercontent.com/incubaid/herolib/refs/heads/development/scripts/install_v.sh' > /tmp/install_v.sh
+bash /tmp/install_v.sh --analyzer --herolib 
+# IMPORTANT: Start a new shell after installation for paths to be set correctly
+```
+
+Alternatively, you can manually set up the environment:
+
+```bash
+mkdir -p ~/code/github/incubaid
+cd ~/code/github/incubaid
+git clone git@github.com:incubaid/herolib.git
+cd herolib
+# checkout development branch for most recent changes
+git checkout development 
+bash install.sh
+```
+
+### Repository Structure
+
+Herolib is an opinionated library primarily used by ThreeFold to automate cloud environments. The repository is organized into several key directories:
+
+- `/lib`: Core library code
+- `/cli`: Command-line interface tools, including the Hero tool
+- `/cookbook`: Examples and guides for using Herolib
+- `/scripts`: Installation and utility scripts
+- `/docs`: Generated documentation
+
+## Development Workflow
+
+### Branching Strategy
+
+- `development`: Main development branch where all features and fixes are merged
+- `main`: Stable release branch
+
+For new features or bug fixes, create a branch from `development` with a descriptive name.
+
+### Making Changes
+
+1. Create a new branch from `development`:
+
+   ```bash
+   git checkout development
+   git pull
+   git checkout -b feature/your-feature-name
+   ```
+
+2. Make your changes, following the code guidelines.
+
+3. Run tests to ensure your changes don't break existing functionality:
+
+   ```bash
+   ./test_basic.vsh
+   ```
+
+4. Commit your changes with clear, descriptive commit messages.
+
+### Testing
+
+Before submitting a pull request, ensure all tests pass:
+
+```bash
+# Run all basic tests
+./test_basic.vsh
+
+# Run tests for a specific module
+vtest ~/code/github/incubaid/herolib/lib/osal/package_test.v
+
+# Run tests for an entire directory
+vtest ~/code/github/incubaid/herolib/lib/osal
+```
+
+The test script (`test_basic.vsh`) manages test execution and caching to optimize performance. It automatically skips tests listed in the ignore or error sections of the script.
+
+### Pull Requests
+
+1. Push your branch to the repository:
+
+   ```bash
+   git push origin feature/your-feature-name
+   ```
+
+2. Create a pull request against the `development` branch.
+
+3. Ensure your PR includes:
+   - A clear description of the changes
+   - Any related issue numbers
+   - Documentation updates if applicable
+
+4. Wait for CI checks to pass and address any feedback from reviewers.
+
+## Code Guidelines
+
+- Follow the existing code style and patterns in the repository
+- Write clear, concise code with appropriate comments
+- Keep modules separate and focused on specific functionality
+- Maintain separation between the jsonschema and jsonrpc modules rather than merging them
+
+## CI/CD Process
+
+The repository uses GitHub Actions for continuous integration and deployment:
+
+### 1. Testing Workflow (`test.yml`)
+
+This workflow runs on every push and pull request to ensure code quality:
+
+- Sets up V and Herolib
+- Runs all basic tests using `test_basic.vsh`
+
+All tests must pass before a PR can be merged to the `development` branch.
+
+### 2. Hero Build Workflow (`hero_build.yml`)
+
+This workflow builds the Hero tool for multiple platforms when a new tag is created:
+
+- Builds for Linux (x86_64, aarch64) and macOS (x86_64, aarch64)
+- Runs all basic tests
+- Creates GitHub releases with the built binaries
+
+### 3. Documentation Workflow (`documentation.yml`)
+
+This workflow automatically updates the documentation on GitHub Pages when changes are pushed to the `development` branch:
+
+- Generates documentation using `doc.vsh`
+- Deploys the documentation to GitHub Pages
+
+## Documentation
+
+To generate documentation locally:
+
+```bash
+cd ~/code/github/incubaid/herolib
+bash doc.sh
+```
+
+The documentation is automatically published to [https://incubaid.github.io/herolib/](https://incubaid.github.io/herolib/) when changes are pushed to the `development` branch.
+
+## Troubleshooting
+
+### TCC Compiler Error on macOS
+
+If you encounter the following error when using TCC compiler on macOS:
+
+```
+In file included from /Users/timurgordon/code/github/vlang/v/thirdparty/cJSON/cJSON.c:42:
+/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/math.h:614: error: ';' expected (got "__fabsf16")
+```
+
+This is caused by incompatibility between TCC and the half precision math functions in the macOS SDK. To fix this issue:
+
+1. Open the math.h file:
+
+   ```bash
+   sudo nano /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/math.h
+   ```
+
+2. Comment out the half precision math functions (around line 612-626).
+
+For more details, see the [README.md](README.md) troubleshooting section.

+## Features
 
-to run the basic tests, important !!!
+Herolib provides a wide range of functionality:
+
+- Cloud automation tools
+- Git operations and management
+
+  ### Offline Mode for Git Operations
+
+  Herolib now supports an `offline` mode for Git operations, which prevents automatic fetching from remote repositories. This can be useful in environments with limited or no internet connectivity, or when you want to avoid network calls during development or testing.
+
+  To enable offline mode:
+
+  - **Via `GitStructureConfig`**: Set the `offline` field to `true` in the `GitStructureConfig` struct.
+  - **Via `GitStructureArgsNew`**: When creating a new `GitStructure` instance using `gittools.new()`, set the `offline` parameter to `true`.
+  - **Via Environment Variable**: Set the `OFFLINE` environment variable to any value (e.g., `export OFFLINE=true`).
+
+  When offline mode is active, `git fetch --all` operations will be skipped, and a debug message "fetch skipped (offline)" will be printed.
+- Documentation building
+- Hero AI integration
+- System management utilities
+- And much more
+
+Check the [cookbook](https://github.com/incubaid/herolib/tree/development/cookbook) for examples and use cases.
+
+## Testing
+
+Running tests is an essential part of development. To run the basic tests:
 
 ```bash
-~/code/github/freeflowuniverse/herolib/test_basic.vsh
+# Run all basic tests
+~/code/github/incubaid/herolib/test_basic.vsh
+
+# Run tests for a specific module
+vtest ~/code/github/incubaid/herolib/lib/osal/package_test.v
+
+# Run tests for an entire directory
+vtest ~/code/github/incubaid/herolib/lib/osal
 ```
 
+The `vtest` command is an alias for testing functionality.

+## Troubleshooting
+
+### TCC Compiler Error on macOS
+
+If you encounter the following error when using TCC compiler on macOS:
+
+```
+In file included from /Users/timurgordon/code/github/vlang/v/thirdparty/cJSON/cJSON.c:42:
+/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/math.h:614: error: ';' expected (got "__fabsf16")
+```
+
+This is caused by incompatibility between TCC and the half precision math functions in the macOS SDK. To fix this issue:
+
+1. Open the math.h file:
+
+   ```bash
+   sudo nano /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/math.h
+   ```
+
+2. Comment out the following lines (around line 612-626):
+
+   ```c
+   /* half precision math functions */
+   // extern _Float16 __fabsf16(_Float16) __API_AVAILABLE(macos(15.0), ios(18.0), watchos(11.0), tvos(18.0));

+# HeroLib AI Prompts (`aiprompts/`)
+
+This directory contains AI-oriented instructions and manuals for working with the Hero tool and the `herolib` codebase.
+
+It is the **entry point for AI agents** that generate or modify code/docs in this repository.
+
+## Scope
+
+- **Global rules for AI and V/Hero usage**  
+  See:
+  - `herolib_start_here.md`
+  - `vlang_herolib_core.md`
+- **Herolib core modules**  
+  See:
+  - `herolib_core/` (core HeroLib modules)
+  - `herolib_advanced/` (advanced topics)
+- **Docusaurus & Site module (Hero docs)**  
+  See:
+  - `docusaurus/docusaurus_ebook_manual.md`
+  - `lib/web/docusaurus/README.md` (authoritative module doc)
+  - `lib/web/site/ai_instructions.md` and `lib/web/site/readme.md`
+- **HeroModels / HeroDB**  
+  See:
+  - `ai_instructions_hero_models.md`
+  - `heromodel_instruct.md`
+- **V language & web server docs** (upstream-style, mostly language-level)  
+  See:
+  - `v_core/`, `v_advanced/`  
+  - `v_veb_webserver/`
+
+## Sources of Truth
+
+For any domain, **code and module-level docs are authoritative**:
+
+- Core install & usage: `herolib/README.md`, scripts under `scripts/`
+- Site module: `lib/web/site/ai_instructions.md`, `lib/web/site/readme.md`
+- Docusaurus module: `lib/web/docusaurus/README.md`, `lib/web/docusaurus/*.v`
+- DocTree client: `lib/data/doctree/client/README.md`
+- HeroModels: `lib/hero/heromodels/*.v` + tests
+
+`aiprompts/` files **must not contradict** these. When in doubt, follow the code / module docs first and treat prompts as guidance.
+
+## Directory Overview
+
+- `herolib_start_here.md` / `vlang_herolib_core.md`  
+  Global AI rules and V/Hero basics.
+- `herolib_core/` & `herolib_advanced/`  
+  Per-module instructions for core/advanced HeroLib features.
+- `docusaurus/`  
+  AI manual for building Hero docs/ebooks with the Docusaurus + Site + DocTree pipeline.
+- `instructions/`  
+  Active, higher-level instructions (e.g. HeroDB base filesystem).
+- `instructions_archive/`  
+  **Legacy / historical** prompt material. See `instructions_archive/README.md`.
+- `todo/`  
+  Meta design/refactor notes (not up-to-date instructions for normal usage).
+- `v_core/`, `v_advanced/`, `v_veb_webserver/`  
+  V language and web framework references used when generating V code.
+- `bizmodel/`, `unpolly/`, `doctree/`, `documentor/`  
+  Domain-specific or feature-specific instructions.
+
+## How to Treat Legacy Material
+
+- Content under `instructions_archive/` is **kept for reference** and may describe older flows (e.g. older documentation or prompt pipelines).  
+  Do **not** use it as a primary source for new work unless explicitly requested.
+- Some prompts mention **Doctree**; the current default docs pipeline uses **DocTree**. Doctree/`doctreeclient` is an alternative/legacy backend.
+
+## Guidelines for AI Agents
+
+- Always:
+  - Respect global rules in `herolib_start_here.md` and `vlang_herolib_core.md`.
+  - Prefer module docs under `lib/` when behavior or parameters differ.
+  - Avoid modifying generated files (e.g. `*_ .v` or other generated artifacts) as instructed.
+- When instructions conflict, resolve as:
+  1. **Code & module docs in `lib/`**
+  2. **AI instructions in `aiprompts/`**
+  3. **Archived docs (`instructions_archive/`) only when explicitly needed**.

+# WARP.md
+
+This file provides guidance to WARP (warp.dev) when working with code in this repository.
+
+## Commands to Use
+
+### Testing
+
+- **Run Tests**: Utilize `vtest ~/code/github/incubaid/herolib/lib/osal/package_test.v` to run specific tests.
+
+## High-Level Architecture
+
+- **Project Structure**: The project is organized into multiple modules located in `lib` and `src` directories. Prioritized compilation and caching strategies are utilized across modules.
+- **Script Handling**: Vlang scripts are crucial and should follow instructions from `aiprompts/vlang_herolib_core.md`.
+
+## Special Instructions
+
+- **Documentation Reference**: Always refer to `aiprompts/vlang_herolib_core.md` for essential instructions regarding Vlang and Heroscript code generation and execution.
+- **Environment Specifics**: Ensure Redis and other dependencies are configured as per scripts provided in the codebase.

-# instructions how to work with heroscript in vlang
-
-## heroscript
-
-Heroscript is our small scripting language which has following structure
-
-an example of a heroscript is
-
-```heroscript
-
-!!mailclient.configure
-	name: 'myname'
-	host: 'localhost'
-	port: 25
-	secure: 1
-	reset: 1 
-	description: '
-		a description can be multiline
-
-		like this
-		'
-
-```
-
-Notice how:
-- every action starts with !!
-	- the first part is the actor, mailclient in this case
-	- the 2e part is the action name, configure in this case
-- multilines are supported see the description field
-
-## how to process heroscript in Vlang
-
-- heroscript can be converted to a struct,
-- the methods available to get the params are in 'params' section further in this doc
-
-
-```vlang
-//the object which will be configured
-pub struct mailclient {
-pub mut:
-	name string
-	host string
-	port int	
-	secure bool
-	description string
-}
-
-mut plbook := playbook.new(text: $the_heroscript_from_above)!
-play_mailclient(mut plbook)! //see below in vlang block there it all happens
-
-pub fn play_mailclient(mut plbook playbook.PlayBook) ! {
-
-	//find all actions are !!$actor.$actionname.  in this case above the actor is !!mailclient, we check with the fitler if it exists, if not we return
-	mailclient_actions := plbook.find(filter: 'mailclient.')!

-# how to use params
-
-works very well in combination with heroscript
-
-## How to get the paramsparser
-
-```v
-import freeflowuniverse.herolib.data.paramsparser
-
-// Create new params from text
-params := paramsparser.new("color:red size:'large' priority:1 enable:true")!
-
-// Or create empty params and add later
-mut params := paramsparser.new_params()
-params.set("color", "red")
-```
-
-## Parameter Format
-
-The parser supports several formats:
-
-1. Key-value pairs: `key:value`
-2. Quoted values: `key:'value with spaces'`
-3. Arguments without keys: `arg1 arg2`
-4. Comments: `// this is a comment`
-
-Example:
-
-```v
-text := "name:'John Doe' age:30 active:true // user details"
-params := paramsparser.new(text)!
-```
-
-## Getting Values
-
-The module provides various methods to retrieve values:
-
-```v
-// Get string value
-name := params.get("name")! // returns "John Doe"
-
-// Get with default value
-color := params.get_default("color", "blue")! // returns "blue" if color not set
-
-// Get as integer
-age := params.get_int("age")! // returns 30

-is_active := params.get_default_true("active")
-

-
-## Type Conversion Methods
-
-The module supports various type conversions:
-
-### Basic Types
-
-- `get_int()`: Convert to int32
-- `get_u32()`: Convert to unsigned 32-bit integer
-- `get_u64()`: Convert to unsigned 64-bit integer
-- `get_u8()`: Convert to unsigned 8-bit integer
-- `get_float()`: Convert to 64-bit float
-- `get_percentage()`: Convert percentage string to float (e.g., "80%" → 0.8)
-
-### Boolean Values
-
-- `get_default_true()`: Returns true if value is empty, "1", "true", "y", or "yes"
-- `get_default_false()`: Returns false if value is empty, "0", "false", "n", or "no"
-
-### Lists
-
-The module provides robust support for parsing and converting lists:
-
-```v
-// Basic list parsing
-names := params.get_list("users")! // parses ["user1", "user2", "user3"]
-
-// With default value
-tags := params.get_list_default("tags", ["default"])!
-
-// Lists with type conversion
-numbers := params.get_list_int("ids")! // converts each item to int
-amounts := params.get_list_f64("prices")! // converts each item to f64
-
-// Name-fixed lists (normalizes each item)
-clean_names := params.get_list_namefix("categories")!
-```
-
-Supported list types:
-
-- `get_list()`: String list
-- `get_list_u8()`, `get_list_u16()`, `get_list_u32()`, `get_list_u64()`: Unsigned integers
-- `get_list_i8()`, `get_list_i16()`, `get_list_int()`, `get_list_i64()`: Signed integers
-- `get_list_f32()`, `get_list_f64()`: Floating point numbers
-
-Each list method has a corresponding `_default` version that accepts a default value.
-
-Valid list formats:
-
-```v
-users: "john, jane,bob"
-ids: "1,2,3,4,5"
-```
-
-### Advanced
-
-```v
-get_map() map[string]string
-
-get_path(key string) !string
-
-get_path_create(key string) !string //will create path if it doesnt exist yet
-
-get_percentage(key string) !f64
-
-get_percentage_default(key string, defval string) !f64
-
-//convert GB, MB, KB to bytes e.g. 10 GB becomes bytes in u64
-get_storagecapacity_in_bytes(key string) !u64
-
-get_storagecapacity_in_bytes_default(key string, defval u64) !u64
-
-get_storagecapacity_in_gigabytes(key string) !u64
-
-//Get Expiration object from time string input input can be either relative or absolute## Relative time
-get_time(key string) !ourtime.OurTime
-
-get_time_default(key string, defval ourtime.OurTime) !ourtime.OurTime
-
-get_time_interval(key string) !Duration
-
-get_timestamp(key string) !Duration
-
-get_timestamp_default(key string, defval Duration) !Duration

-# how to work with heroscript in vlang
-
-## heroscript
-
-Heroscript is our small scripting language which has following structure
-
-an example of a heroscript is
-
-```heroscript
-
-!!dagu.script_define
-	name: 'test_dag'
-	homedir:''
-	title:'a title'
-	reset:1
-	start:true //trie or 1 is same
-	colors: 'green,red,purple' //lists are comma separated
-	description: '
-		a description can be multiline
-
-		like this
-		'
-
-
-!!dagu.add_step
-	dag: 'test_dag'
-	name: 'hello_world'
-	command: 'echo hello world'
-
-!!dagu.add_step
-	dag: 'test_dag'
-	name: 'last_step'
-	command: 'echo last step'
-
-
-```
-
-Notice how:
-- every action starts with !!
-	- the first part is the actor e.g. dagu in this case
-	- the 2e part is the action name
-- multilines are supported see the description field
-
-## how to process heroscript in Vlang
-
-- heroscript can be converted to a struct,
-- the methods available to get the params are in 'params' section further in this doc
-
-
-```vlang
-
-fn test_play_dagu() ! {
-	mut plbook := playbook.new(text: thetext_from_above)!
-	play_dagu(mut plbook)! //see below in vlang block there it all happens
-}
-
-
-pub fn play_dagu(mut plbook playbook.PlayBook) ! {
-
-	//find all actions are !!$actor.$actionname.  in this case above the actor is !!dagu, we check with the fitler if it exists, if not we return
-	dagu_actions := plbook.find(filter: 'dagu.')!
-	if dagu_actions.len == 0 {
-		return
-	}	
-	play_dagu_basic(mut plbook)!
-}
-
-pub struct DaguScript {
-pub mut:
-	name string
-	homedir string
-	title string
-	reset bool
-	start bool
-	colors []string
-}
-
-// play_dagu plays the dagu play commands
-pub fn play_dagu_basic(mut plbook playbook.PlayBook) ! {
-
-	//now find the specific ones for dagu.script_define
-	mut actions := plbook.find(filter: 'dagu.script_define')!
-
-	if actions.len > 0 {
-		for myaction in actions {
-			mut p := myaction.params       //get the params object from the action object, this can then be processed using the param getters      
-			mut obj := DaguScript{
-				//INFO: all details about the get methods can be found in 'params get methods' section
-				name : p.get('name')! //will give error if not exist			
-				homedir : p.get('homedir')!
-				title : p.get_default('title', 'My Hero DAG')!  //uses a default if not set
-				reset : p.get_default_false('reset') 
-				start : p.get_default_true('start')
-				colors : p.get_list('colors')
-				description : p.get_default('description','')!					
-			}
-			... 
-		}
-	}
-
-    //there can be more actions which will have other filter

-## how internally a heroscript gets parsed for params
-
-- example to show how a heroscript gets parsed in action with params
-- params are part of action object
-
-```heroscript
-example text to parse (heroscript)
-
-id:a1 name6:aaaaa
-name:'need to do something 1' 
-description:
-    '
-    ## markdown works in it
-    description can be multiline
-    lets see what happens
-
-    - a
-    - something else
-
-    ### subtitle
-    '
-
-name2:   test
-name3: hi 
-name10:'this is with space'  name11:aaa11
-
-name4: 'aaa'
-
-//somecomment
-name5:   'aab'
-```
-
-the params are part of the action and are represented as follow for the above:
-
-```vlang
-Params{
-    params: [Param{
-        key: 'id'
-        value: 'a1'

+# HeroDB Model Creation Instructions for AI
+
+## Overview
+
+This document provides clear instructions for AI agents to create new HeroDB models similar to `message.v`.
+These models are used to store structured data in Redis using the HeroDB system.
+The `message.v` example can be found in `lib/hero/heromodels/message.v`.
+
+## Key Concepts
+
+- Models must implement serialization/deserialization using the `encoder` module
+- Models inherit from the `Base` struct which provides common fields
+- The database uses a factory pattern for model access
+
+## File Structure
+
+Create a new file in `lib/hero/heromodels/` with the model name (e.g., `calendar.v`).
+
+## Required Components
+
+### 1. Model Struct Definition
+
+Define your model struct with the following pattern:
+
+```v
+@[heap]
+pub struct Calendar {
+ db.Base // Inherit from Base struct
+pub mut:
+ // Add your specific fields here
+ title       string
+ start_time  i64
+ end_time    i64
+ location    string
+ attendees   []string
+}
+```
+
+### 2. Type Name Method
+
+Implement a method to return the model's type name:
+
+```v
+pub fn (self Calendar) type_name() string {
+ return 'calendar'
+}
+```
+
+### 3. Serialization (dump) Method
+
+Implement the `dump` method to serialize your struct's fields using the encoder:
+
+```v
+pub fn (self Calendar) dump(mut e &encoder.Encoder) ! {
+ e.add_string(self.title)
+ e.add_i64(self.start_time)
+ e.add_i64(self.end_time)
+ e.add_string(self.location)
+ e.add_list_string(self.attendees)
+}
+```
+
+### 4. Deserialization (load) Method
+
+Implement the `load` method to deserialize your struct's fields:
+
+```v
+fn (mut self DBCalendar) load(mut o Calendar, mut e &encoder.Decoder) ! {
+ o.title = e.get_string()!
+ o.start_time = e.get_i64()!
+ o.end_time = e.get_i64()!
+ o.location = e.get_string()!
+ o.attendees = e.get_list_string()!
+}
+```
+
+### 5. Model Arguments Struct
+
+Define a struct for creating new instances of your model:
+
+```v
+@[params]
+pub struct CalendarArg {
+pub mut:
+ title      string @[required]
+ start_time i64
+ end_time   i64
+ location   string
+ attendees  []string
+}
+```
+
+### 6. Database Wrapper Struct
+
+Create a database wrapper struct for your model:
+
+```v
+pub struct DBCalendar {
+pub mut:
+ db &db.DB @[skip; str: skip]
+}
+```
+
+### 7. Factory Integration
+
+Add your model to the ModelsFactory struct in `factory.v`:
+
+```v
+pub struct ModelsFactory {
+pub mut:
+ calendar DBCalendar
+ // ... other models
+}
+```
+
+And initialize it in the `new()` function:
+
+```v
+pub fn new() !ModelsFactory {
+ mut mydb := db.new()!
+ return ModelsFactory{
+  messages: DBCalendar{
+   db: &mydb
+  }
+  // ... initialize other models
+ }
+}
+```
+
+## Encoder Methods Reference
+
+Use these methods for serialization/deserialization:
+
+### Encoder (Serialization)
+
+- `e.add_bool(val bool)`
+- `e.add_u8(val u8)`
+- `e.add_u16(val u16)`
+- `e.add_u32(val u32)`
+- `e.add_u64(val u64)`
+- `e.add_i8(val i8)`
+- `e.add_i16(val i16)`
+- `e.add_i32(val i32)`
+- `e.add_i64(val i64)`
+- `e.add_f32(val f32)`
+- `e.add_f64(val f64)`
+- `e.add_string(val string)`
+- `e.add_list_bool(val []bool)`
+- `e.add_list_u8(val []u8)`
+- `e.add_list_u16(val []u16)`
+- `e.add_list_u32(val []u32)`
+- `e.add_list_u64(val []u64)`
+- `e.add_list_i8(val []i8)`
+- `e.add_list_i16(val []i16)`
+- `e.add_list_i32(val []i32)`
+- `e.add_list_i64(val []i64)`
+- `e.add_list_f32(val []f32)`
+- `e.add_list_f64(val []f64)`
+- `e.add_list_string(val []string)`
+
+### Decoder (Deserialization)
+
+- `e.get_bool()!`
+- `e.get_u8()!`
+- `e.get_u16()!`
+- `e.get_u32()!`
+- `e.get_u64()!`
+- `e.get_i8()!`
+- `e.get_i16()!`
+- `e.get_i32()!`
+- `e.get_i64()!`
+- `e.get_f32()!`
+- `e.get_f64()!`
+- `e.get_string()!`
+- `e.get_list_bool()!`
+- `e.get_list_u8()!`
+- `e.get_list_u16()!`
+- `e.get_list_u32()!`
+- `e.get_list_u64()!`
+- `e.get_list_i8()!`
+- `e.get_list_i16()!`
+- `e.get_list_i32()!`
+- `e.get_list_i64()!`
+- `e.get_list_f32()!`
+- `e.get_list_f64()!`
+- `e.get_list_string()!`
+
+## CRUD Methods Implementation
+
+### Create New Instance
+
+```v
+pub fn (mut self DBCalendar) new(args CalendarArg) !Calendar {
+ mut o := Calendar{
+  title:      args.title
+  start_time: args.start_time
+  end_time:   args.end_time
+  location:   args.location
+  attendees:  args.attendees
+  updated_at: ourtime.now().unix()
+ }
+ return o
+}
+```
+
+### Save to Database
+
+```v
+pub fn (mut self DBCalendar) set(o Calendar) !Calendar {
+ return self.db.set[Calendar](o)!
+}
+```
+
+### Retrieve from Database
+
+```v
+pub fn (mut self DBCalendar) get(id u32) !Calendar {
+ mut o, data := self.db.get_data[Calendar](id)!
+ mut e_decoder := encoder.decoder_new(data)
+ self.load(mut o, mut e_decoder)!
+ return o
+}
+```
+
+### Delete from Database
+
+```v
+pub fn (mut self DBCalendar) delete(id u32) ! {
+ self.db.delete[Calendar](id)!
+}
+```
+
+### Check Existence
+
+```v
+pub fn (mut self DBCalendar) exist(id u32) !bool {
+ return self.db.exists[Calendar](id)!
+}
+```
+
+### List All Objects
+
+```v
+pub fn (mut self DBCalendar) list() ![]Calendar {
+ return self.db.list[Calendar]()!.map(self.get(it)!)
+}
+```
+
+## Example Usage Script
+
+Create a `.vsh` script in `examples/hero/heromodels/` to demonstrate usage:
+
+```v
+#!/usr/bin/env -S v -n -w -cg -gc none -cc tcc -d use_openssl -enable-globals run
+
+import incubaid.herolib.core.redisclient
+import incubaid.herolib.hero.heromodels
+
+mut mydb := heromodels.new()!
+
+// Create a new object
+mut o := mydb.calendar.new(
+ title: 'Meeting'
+ start_time: 1672531200
+ end_time: 1672534800
+ location: 'Conference Room'
+ attendees: ['john@example.com', 'jane@example.com']
+)!
+
+// Save to database
+oid := mydb.calendar.set(o)!
+println('Created object with ID: ${oid}')
+
+// Retrieve from database
+mut o2 := mydb.calendar.get(oid)!
+println('Retrieved object: ${o2}')
+
+// List all objects
+mut objects := mydb.calendar.list()!
+println('All objects: ${objects}')
+```
+
+## Best Practices
+
+1. Always inherit from `db.Base` struct
+2. Implement all required methods (`type_name`, `dump`, `load`)
+3. Use the encoder methods for consistent serialization
+4. Handle errors appropriately with `!` or `or` blocks
+5. Keep field ordering consistent between `dump` and `load` methods
+6. Use snake_case for field names
+7. Add `@[required]` attribute to mandatory fields in argument structs
+8. Initialize timestamps using `ourtime.now().unix()`
+
+## Implementation Steps Summary
+
+1. Create model struct inheriting from `db.Base`
+2. Implement `type_name()` method
+3. Implement `dump()` method using encoder
+4. Implement `load()` method using decoder
+5. Create argument struct with `@[params]` attribute
+6. Create database wrapper struct
+7. Add model to `ModelsFactory` in `factory.v`
+8. Implement CRUD methods
+9. Create example usage script
+10. Test the implementation with the example script

-# datatypes
-
-This module provides implementations of less frequently used, but still common data types.
-
-V's `builtin` module is imported implicitly, and has implementations for arrays, maps and strings. These are good for many applications, but there are a plethora of other useful data structures/containers, like linked lists, priority queues, trees, etc, that allow for algorithms with different time complexities, which may be more suitable for your specific application.
-
-It is implemented using generics, that you have to specialise for the type of your actual elements. For example:
-```v
-import datatypes
-
-mut stack := datatypes.Stack[int]{}
-stack.push(1)
-println(stack)
-```
-
-## Currently Implemented Datatypes:
-
-- [x] Linked list
-- [x] Doubly linked list
-- [x] Stack (LIFO)
-- [x] Queue (FIFO)
-- [x] Min heap (priority queue)
-- [x] Set
-- [x] Quadtree
-- [x] Bloom filter
-- [ ] ...

+# HeroLib Docusaurus Ebook Manual for AI Prompts
+
+This manual provides a comprehensive guide on how to leverage HeroLib's Docusaurus integration, Doctree, and HeroScript to create and manage technical ebooks, optimized for AI-driven content generation and project management.
+
+## Quick Start - Recommended Ebook Structure
+
+The recommended directory structure for an ebook:
+
+```
+my_ebook/
+├── scan.hero              # DocTree collection scanning
+├── config.hero            # Site configuration
+├── menus.hero             # Navbar and footer configuration
+├── include.hero           # Docusaurus define and doctree export
+├── 1_intro.heroscript     # Page definitions (numbered for ordering)
+├── 2_concepts.heroscript  # More page definitions
+└── 3_advanced.heroscript  # Additional pages
+```
+
+**Running an ebook:**
+
+```bash
+# Start development server
+hero docs -d -p /path/to/my_ebook
+
+# Build for production
+hero docs -p /path/to/my_ebook
+```
+
+## 1. Core Concepts
+
+To effectively create ebooks with HeroLib, it's crucial to understand the interplay of three core components:
+
+* **HeroScript**: A concise scripting language used to define the structure, configuration, and content flow of your Docusaurus site. It acts as the declarative interface for the entire process. Files use `.hero` extension for configuration and `.heroscript` for page definitions.
+* **Docusaurus**: A popular open-source static site generator. HeroLib uses Docusaurus as the underlying framework to render your ebook content into a navigable website.
+* **DocTree**: HeroLib's document collection layer. DocTree scans and exports markdown "collections" and "pages" that Docusaurus consumes.
+
+## 2. Setting Up a Docusaurus Project with HeroLib
+
+The `docusaurus` module in HeroLib provides the primary interface for managing your ebook projects.
+
+### 2.1. Defining the Docusaurus Factory (`docusaurus.define`)
+
+The `docusaurus.define` HeroScript directive configures the global settings for your Docusaurus build environment. This is typically used once at the beginning of your main HeroScript configuration.
+
+**HeroScript Example:**
+
+```heroscript
+!!docusaurus.define
+    name:"my_ebook"                  // must match the site name from !!site.config
+    path_build: "/tmp/my_ebook_build"
+    path_publish: "/tmp/my_ebook_publish"
+    reset: true                      // clean build dir before building (optional)
+    install: true                    // run bun install if needed (optional)
+    template_update: true            // update the Docusaurus template (optional)
+    doctree_dir: "/tmp/doctree_export"   // where DocTree exports collections
+    use_doctree: true                  // use DocTree as content backend
+```
+
+**Arguments:**
+
+* `name` (string, required): The site/factory name. Must match the `name` used in `!!site.config` so Docusaurus can find the corresponding site definition.
+* `path_build` (string, optional): The local path where the Docusaurus site will be built. Defaults to `~/hero/var/docusaurus/build`.
+* `path_publish` (string, optional): The local path where the final Docusaurus site will be published (e.g., for deployment). Defaults to `~/hero/var/docusaurus/publish`.
+* `reset` (boolean, optional): If `true`, clean the build directory before starting.
+* `install` (boolean, optional): If `true`, run dependency installation (e.g., `bun install`).
+* `template_update` (boolean, optional): If `true`, update the Docusaurus template.
+* `doctree_dir` (string, optional): Directory where DocTree exports collections (used by the DocTree client in `lib/data/doctree/client`).
+* `use_doctree` (boolean, optional): If `true`, use the DocTree client as the content backend (default behavior).
+
+### 2.2. Adding a Docusaurus Site (`docusaurus.add`)
+
+The `docusaurus.add` directive defines an individual Docusaurus site (your ebook). You can specify the source of your documentation content, whether it's a local path or a Git repository.
+
+**HeroScript Example (Local Content):**
+
+```heroscript
+!!docusaurus.add
+    name:"my_local_ebook"
+    path:"./my_ebook_content" // Path to your local docs directory
+    open:true // Open in browser after generation
+```
+
+**HeroScript Example (Git Repository Content):**
+
+```heroscript
+!!docusaurus.add
+    name:"tfgrid_tech_ebook"
+    git_url:"https://git.ourworld.tf/tfgrid/docs_tfgrid4/src/branch/main/ebooks/tech"
+    git_reset:true // Reset Git repository before pulling
+    git_pull:true // Pull latest changes
+    git_root:"/tmp/git_clones" // Optional: specify a root directory for git clones
+```
+
+**Arguments:**
+
+* `name` (string, optional): A unique name for your Docusaurus site/ebook. Defaults to "main".
+* `path` (string, optional): The local file system path to the root of your documentation content (e.g., where your `docs` and `cfg` directories are).
+* `git_url` (string, optional): A Git URL to a repository containing your documentation content. HeroLib will clone/pull this repository.
+* `git_reset` (boolean, optional): If `true`, the Git repository will be reset to a clean state before pulling. Default is `false`.
+* `git_pull` (boolean, optional): If `true`, the Git repository will be pulled to get the latest changes. Default is `false`.
+* `git_root` (string, optional): An optional root directory where Git repositories will be cloned.
+* `nameshort` (string, optional): A shorter name for the Docusaurus site. Defaults to the value of `name`.
+* `path_publish` (string, optional): Overrides the factory's `path_publish` for this specific site.
+* `production` (boolean, optional): Overrides the factory's `production` setting for this specific site.
+* `watch_changes` (boolean, optional): If `true`, HeroLib will watch for changes in your source `docs` directory and trigger rebuilds. Default is `true`.
+* `update` (boolean, optional): If `true`, this specific documentation will be updated. Default is `false`.
+* `open` (boolean, optional): If `true`, the Docusaurus site will be opened in your default browser after generation/development server start. Default is `false`.
+* `init` (boolean, optional): If `true`, the Docusaurus site will be initialized (e.g., creating missing `docs` directories). Default is `false`.
+
+## 3. Structuring Content with HeroScript and Doctree
+
+The actual content and structure of your ebook are defined using HeroScript directives within your site's configuration files (e.g., in a `cfg` directory within your `path` or `git_url` source).
+
+### 3.1. Site Configuration (`site.config`, `site.config_meta`)
+
+These directives define the fundamental properties and metadata of your Docusaurus site.
+
+**HeroScript Example:**
+
+```heroscript

+  * `description` (string, optional): Specific description for SEO.
+  * `keywords` (string, optional): Comma-separated keywords for SEO.
+
+### 3.2. Navigation Bar (`site.navbar`, `site.navbar_item`)
+
+Define the main navigation menu of your Docusaurus site.
+
+**HeroScript Example:**
+
+```heroscript
+!!site.navbar
+    title:"Ebook Navigation"
+    logo_alt:"Ebook Logo"
+    logo_src:"img/logo.svg"
+    logo_src_dark:"img/logo_dark.svg"
+
+!!site.navbar_item
+    label:"Introduction"
+    to:"/docs/intro" // Internal Docusaurus path
+    position:"left"
+
+!!site.navbar_item
+    label:"External Link"
+    href:"https://example.com/external" // External URL
+    position:"right"
+```
+
+**Arguments:**
+
+* **`site.navbar`**:
+  * `title` (string, optional): Title displayed in the navbar. Defaults to `site.config.title`.
+  * `logo_alt` (string, optional): Alt text for the logo.
+  * `logo_src` (string, optional): Path to the light mode logo.
+  * `logo_src_dark` (string, optional): Path to the dark mode logo.

+  * `href` (string, optional): External URL for the link.
+  * `to` (string, optional): Internal Docusaurus path (e.g., `/docs/my-page`).
+  * `position` (string, optional): "left" or "right" for placement in the navbar. Defaults to "right".
+
+### 3.3. Footer (`site.footer`, `site.footer_item`)
+
+Configure the footer section of your Docusaurus site.
+
+**HeroScript Example:**
+
+```heroscript
+!!site.footer
+    style:"dark" // "dark" or "light"
+
+!!site.footer_item
+    title:"Resources" // Grouping title for footer links
+    label:"API Documentation"
+    href:"https://api.example.com/docs"
+
+!!site.footer_item
+    title:"Community"
+    label:"GitHub"
+    href:"https://github.com/my-org"
+```
+
+**Arguments:**
+
+* **`site.footer`**:
+  * `style` (string, optional): "dark" or "light" style for the footer. Defaults to "dark".
+* **`site.footer_item`**:
+  * `title` (string, required): The title under which this item will be grouped in the footer.
+  * `label` (string, required): Text displayed for the footer link.
+  * `href` (string, optional): External URL for the link.
+  * `to` (string, optional): Internal Docusaurus path.
+
+### 3.4. Publish Destinations (`site.publish`, `site.publish_dev`)
+
+Specify where the built Docusaurus site should be deployed. This typically involves an SSH connection defined elsewhere (e.g., `!!site.ssh_connection`).
+
+**HeroScript Example:**
+
+```heroscript
+!!site.publish
+    ssh_name:"production_server" // Name of a pre-defined SSH connection
+    path:"/var/www/my-ebook"     // Remote path on the server
+
+!!site.publish_dev
+    ssh_name:"dev_server"
+    path:"/tmp/dev-ebook"
+```
+
+**Arguments:**
+
+* `ssh_name` (string, required): The name of the SSH connection to use for deployment.
+* `path` (string, required): The destination path on the remote server.
+
+### 3.5. Importing External Content (`site.import`)
+
+This powerful feature allows you to pull markdown content and assets from other Git repositories directly into your Docusaurus site's `docs` directory, with optional text replacement. This is ideal for integrating shared documentation or specifications.
+
+**HeroScript Example:**
+
+```heroscript
+!!site.import
+    url:'https://git.ourworld.tf/tfgrid/docs_tfgrid4/src/branch/main/collections/cloud_reinvented'
+    dest:'cloud_reinvented' // Destination subdirectory within your Docusaurus docs folder
+    replace:'NAME:MyName, URGENCY:red' // Optional: comma-separated key:value pairs for text replacement
+```
+
+**Arguments:**
+
+* `url` (string, required): The Git URL of the repository or specific path within a repository to import.
+* `dest` (string, required): The subdirectory within your Docusaurus `docs` folder where the imported content will be placed.
+* `replace` (string, optional): A comma-separated string of `KEY:VALUE` pairs. During import, all occurrences of `${KEY}` in the imported content will be replaced with `VALUE`.
+
+### 3.6. Defining Pages and Categories (`site.page_category`, `site.page`)
+
+This is where you define the actual content pages and how they are organized into categories within your Docusaurus sidebar.
+
+**HeroScript Example:**
+
+```heroscript
+// Define a category
+!!site.page_category name:'introduction' label:"Introduction to Ebook"
+
+// Define pages - first page specifies collection, subsequent pages reuse it
+!!site.page src:"my_collection:chapter_1_overview"
+    title:"Chapter 1: Overview"
+    description:"A brief introduction to the ebook's content."
+
+!!site.page src:"chapter_2_basics"
+    title:"Chapter 2: Basics"
+
+// New category with new collection
+!!site.page_category name:'advanced' label:"Advanced Topics"
+
+!!site.page src:"advanced_collection:performance"
+    title:"Performance Tuning"
+    hide_title:true
+```
+
+**Arguments:**
+
+* **`site.page_category`**:
+  * `name` (string, required): Category identifier (used internally).
+  * `label` (string, required): The display name for the category in the sidebar.
+  * `position` (int, optional): The order of the category in the sidebar (auto-incremented if omitted).
+* **`site.page`**:
+  * `src` (string, required): **Crucial for DocTree/collection integration.** Format: `collection_name:page_name` for the first page, or just `page_name` to reuse the previous collection.
+  * `title` (string, optional): The title of the page. If not provided, HeroLib extracts it from the markdown `# Heading` or uses the page name.
+  * `description` (string, optional): A short description for the page, used in frontmatter.
+  * `hide_title` (boolean, optional): If `true`, the title will not be displayed on the page itself.
+  * `draft` (boolean, optional): If `true`, the page will be hidden from navigation.
+
+### 3.7. Collections and DocTree/Doctree Integration
+
+The `site.page` directive's `src` parameter (`collection_name:page_name`) is the bridge to your content collections.
+
+**Current default: DocTree export**
+
+1. **Collections**: DocTree exports markdown files into collections under an `export_dir` (see `lib/data/doctree/client`).
+2. **Export step**: A separate process (DocTree) writes the collections into `doctree_dir` (e.g., `/tmp/doctree_export`), following the `content/` + `meta/` structure.
+3. **Docusaurus consumption**: The Docusaurus module uses the DocTree client (`doctree_client`) to resolve `collection_name:page_name` into markdown content and assets when generating docs.
+
+**Alternative: Doctree/`doctreeclient`**
+
+In older setups, or when explicitly configured, Doctree and `doctreeclient` can still be used to provide the same `collection:page` model:
+
+1. **Collections**: Doctree organizes markdown files into logical groups called "collections." A collection is typically a directory containing markdown files and an empty `.collection` file.
+2. **Scanning**: You define which collections Doctree should scan using `!!doctree.scan` in a HeroScript file (e.g., `doctree.heroscript`):
+
+    ```heroscript
+    !!doctree.scan git_url:"https://git.ourworld.tf/tfgrid/docs_tfgrid4/src/branch/main/collections"
+    ```
+
+    This will pull the `collections` directory from the specified Git URL and make its contents available to Doctree.
+3. **Page Retrieval**: When `site.page` references `src:"my_collection:my_page"`, the client (`doctree_client` or `doctreeclient`, depending on configuration) fetches the content of `my_page.md` from the `my_collection` collection.
+
+## 4. Building and Developing Your Ebook
+
+Once your HeroScript configuration is set up, HeroLib provides commands to build and serve your Docusaurus ebook.
+
+### 4.1. Generating Site Files (`site.generate()`)
+
+The `site.generate()` function (called internally by `build`, `dev`, etc.) performs the core file generation:
+
+* Copies Docusaurus template files.
+* Copies your site's `src` and `static` assets.
+* Generates Docusaurus configuration JSON files (`main.json`, `navbar.json`, `footer.json`) from your HeroScript `site.config`, `site.navbar`, and `site.footer` directives.
+* Copies your source `docs` directory.
+* Processes `site.page` and `site.page_category` directives using the `sitegen` module to create the final markdown files and `_category_.json` files in the Docusaurus `docs` directory, fetching content from Doctree.
+* Handles `site.import` directives, pulling external content and performing replacements.
+
+### 4.2. Local Development
+
+HeroLib integrates with Docusaurus's development server for live preview.
+
+**HeroScript Example:**
+
+can be stored as example_docusaurus.vsh and then used to generate and develop an ebook
+
+```v
+#!/usr/bin/env -S v -n -w -gc none  -cg -cc tcc -d use_openssl -enable-globals run
+
+import incubaid.herolib.web.docusaurus
+import os
+
+const cfgpath = os.dir(@FILE)
+
+docusaurus.new(
+ heroscript: '
+
+ // !!docusaurus.define
+ //  path_build: "/tmp/docusaurus_build"
+ //  path_publish: "/tmp/docusaurus_publish"
+
+ !!docusaurus.add name:"tfgrid_docs" 
+  path:"${cfgpath}"
+
+ !!docusaurus.dev
+
+ '
+)!
+
+```
+
+the following script suggest to call it do.vsh and put in directory of where the ebook is
+
+```v
+#!/usr/bin/env -S v -n -w -gc none  -cg -cc tcc -d use_openssl -enable-globals run
+
+import incubaid.herolib.web.docusaurus
+
+const cfgpath = os.dir(@FILE) + '/cfg'
+
+docusaurus.new(heroscript_path:cfgpath)!
+```
+
+by just called do.vsh we can execute on the ebook

+# Pathlib Module: Advanced Listing and Filtering
+
+The `pathlib` module provides powerful capabilities for listing and filtering files and directories, especially through its `list` method. This document explains how to leverage advanced features like regular expressions and various filtering options.
+
+## Advanced File Listing with `path.list()`
+
+The `path.list()` method allows you to retrieve a `PathList` object containing `Path` objects that match specified criteria.
+
+### `ListArgs` Parameters
+
+The `list` method accepts a `ListArgs` struct to control its behavior:
+
+```v
+pub struct ListArgs {
+pub mut:
+ regex         []string // A slice of regular expressions to filter files.
+ recursive     bool = true // Whether to list files recursively (default true).
+ ignore_default bool = true // Whether to ignore files starting with . and _ (default true).
+ include_links bool // Whether to include symbolic links in the list.
+ dirs_only     bool // Whether to include only directories in the list.
+ files_only    bool // Whether to include only files in the list.
+}
+```
+
+### Usage Examples
+
+Here are examples demonstrating how to use these advanced filtering options:
+
+#### 1. Listing Files by Regex Pattern
+
+You can use regular expressions to filter files based on their names or extensions. The `regex` parameter accepts a slice of strings, where each string is a regex pattern.
+
+```v
+import incubaid.herolib.core.pathlib
+
+// Get a directory path
+mut dir := pathlib.get('/some/directory')!
+
+// List only Vlang files (ending with .v)
+mut vlang_files := dir.list(
+    regex: [r'.*\.v$']
+)!
+
+// List only image files (png, jpg, svg, jpeg)
+mut image_files := dir.list(
+    regex: [r'.*\.png$', r'.*\.jpg$', r'.*\.svg$', r'.*\.jpeg$']
+)!
+
+// List files containing "test" in their name (case-insensitive)
+mut test_files := dir.list(
+    regex: [r'(?i).*test.*'] // (?i) makes the regex case-insensitive
+)!
+
+for path_obj in vlang_files.paths {
+    println(path_obj.path)
+}
+```
+
+#### 2. Controlling Recursion
+
+By default, `list()` is recursive. You can disable recursion to list only items in the current directory.
+
+```v
+import incubaid.herolib.core.pathlib
+
+mut dir := pathlib.get('/some/directory')!
+
+// List only top-level files and directories (non-recursive)
+mut top_level_items := dir.list(
+    recursive: false
+)!
+
+for path_obj in top_level_items.paths {
+    println(path_obj.path)
+}
+```
+
+#### 3. Including or Excluding Hidden Files
+
+The `ignore_default` parameter controls whether files and directories starting with `.` or `_` are ignored.
+
+```v
+import incubaid.herolib.core.pathlib
+
+mut dir := pathlib.get('/some/directory')!
+
+// List all files and directories, including hidden ones
+mut all_items := dir.list(
+    ignore_default: false
+)!
+
+for path_obj in all_items.paths {
+    println(path_obj.path)
+}
+```
+
+#### 4. Including Symbolic Links
+
+By default, symbolic links are ignored when walking the directory structure. Set `include_links` to `true` to include them.
+
+```v
+import incubaid.herolib.core.pathlib
+
+mut dir := pathlib.get('/some/directory')!
+
+// List files and directories, including symbolic links
+mut items_with_links := dir.list(
+    include_links: true
+)!
+
+for path_obj in items_with_links.paths {
+    println(path_obj.path)
+}
+```
+
+#### 5. Listing Only Directories or Only Files
+
+Use `dirs_only` or `files_only` to restrict the results to only directories or only files.
+
+```v
+import incubaid.herolib.core.pathlib
+
+mut dir := pathlib.get('/some/directory')!
+
+// List only directories (recursive)
+mut only_dirs := dir.list(
+    dirs_only: true
+)!
+
+// List only files (non-recursive)
+mut only_files := dir.list(
+    files_only: true,
+    recursive: false
+)!
+
+for path_obj in only_dirs.paths {
+    println(path_obj.path)
+}
+```
+
+By combining these parameters, you can create highly specific and powerful file system listing operations tailored to your needs.

+# Builder Module: System Automation and Remote Execution
+
+The `builder` module in Herolib provides a powerful framework for automating system tasks and executing commands on both local and remote machines. It offers a unified interface to manage nodes, execute commands, perform file operations, and maintain persistent state.
+
+## Key Components
+
+- **`BuilderFactory`**: Responsible for creating and managing `Node` instances.
+- **`Node`**: Represents a target system (local or remote). It encapsulates system properties (platform, CPU type, environment variables) and provides methods for interaction.
+- **`Executor`**: An interface (implemented by `ExecutorLocal` and `ExecutorSSH`) that handles the actual command execution and file operations on the target system.
+- **NodeDB (via `Node.done` map)**: A key-value store within each `Node` for persistent state, caching, and tracking execution history.
+
+## Getting Started
+
+### Initializing a Builder and Node
+
+First, import the `builder` module and create a new `BuilderFactory` instance. Then, create a `Node` object, which can represent either the local machine or a remote server.
+
+```v
+import incubaid.herolib.builder
+
+// Create a new builder factory
+mut b := builder.new()!
+
+// Create a node for the local machine
+mut local_node := b.node_local()!
+
+// Create a node for a remote server via SSH
+// Format: "user@ip_address:port" or "ip_address:port" or "ip_address"
+mut remote_node := b.node_new(ipaddr: "root@195.192.213.2:2222")!
+
+// Node with custom name and debug enabled
+mut named_debug_node := b.node_new(
+    name: "my_remote_server",
+    ipaddr: "user@server.example.com:22",
+    debug: true
+)!
+```
+
+### `Node` Properties
+
+A `Node` object automatically detects and caches system information. You can access these properties:
+
+```v
+// Get platform type (e.g., .osx, .ubuntu, .alpine, .arch)
+println(node.platform)
+
+// Get CPU architecture (e.g., .intel, .arm)
+println(node.cputype)
+
+// Get hostname
+println(node.hostname)
+
+// Get environment variables
+env_vars := node.environ_get()!
+println(env_vars['HOME'])
+
+// Get node information (category, sshkey, user, ipaddress, port)
+info := node.info()
+println(info['category'])
+```
+
+## Command Execution
+
+The `Node` object provides methods to execute commands on the target system.
+
+### `node.exec(args ExecArgs) !string`
+
+Executes a command and returns its standard output.
+
+```v
+import incubaid.herolib.builder { ExecArgs }
+
+// Execute a command with stdout
+result := node.exec(cmd: "ls -la /tmp", stdout: true)!
+println(result)
+
+// Execute silently (no stdout)
+node.exec(cmd: "mkdir -p /tmp/my_dir", stdout: false)!
+```
+
+### `node.exec_silent(cmd string) !string`
+
+Executes a command silently (no stdout) and returns its output.
+
+```v
+output := node.exec_silent("echo 'Hello from remote!'")!
+println(output)
+```
+
+### `node.exec_interactive(cmd string) !`
+
+Executes a command in an interactive shell.
+
+```v
+// This will open an interactive shell session
+node.exec_interactive("bash")!
+```
+
+### `node.exec_cmd(args NodeExecCmd) !string`
+
+A more advanced command execution method that supports caching, periodic execution, and temporary script handling.
+
+```v
+import incubaid.herolib.builder { NodeExecCmd }
+
+// Execute a command, cache its result for 24 hours (48*3600 seconds)
+// and provide a description for logging.
+result := node.exec_cmd(
+    cmd: "apt-get update",
+    period: 48 * 3600,
+    description: "Update system packages"
+)!
+println(result)
+
+// Execute a multi-line script
+script_output := node.exec_cmd(
+    cmd: "
+        echo 'Starting script...'
+        ls -la /
+        echo 'Script finished.'
+    ",
+    name: "my_custom_script",
+    stdout: true
+)!
+println(script_output)
+```
+
+### `node.exec_retry(args ExecRetryArgs) !string`
+
+Executes a command with retries until it succeeds or a timeout is reached.
+
+```v
+import incubaid.herolib.builder { ExecRetryArgs }
+
+// Try to connect to a service, retrying every 100ms for up to 10 seconds
+result := node.exec_retry(
+    cmd: "curl --fail http://localhost:8080/health",
+    retrymax: 100, // 100 retries
+    period_milli: 100, // 100ms sleep between retries
+    timeout: 10 // 10 seconds total timeout
+)!
+println("Service is up: ${result}")
+```
+
+### `node.cmd_exists(cmd string) bool`
+
+Checks if a command exists on the target system.
+
+```v
+if node.cmd_exists("docker") {
+    println("Docker is installed.")
+} else {
+    println("Docker is not installed.")
+}
+```
+
+## File System Operations
+
+The `Node` object provides comprehensive file and directory management capabilities.
+
+### `node.file_write(path string, text string) !`
+
+Writes content to a file on the target system.
+
+```v
+node.file_write("/tmp/my_file.txt", "This is some content.")!
+```
+
+### `node.file_read(path string) !string`
+
+Reads content from a file on the target system.

+```v
+content := node.file_read("/tmp/my_file.txt")!
+println(content)
+```
+
+### `node.file_exists(path string) bool`
+
+Checks if a file or directory exists on the target system.
+
+```v
+if node.file_exists("/tmp/my_file.txt") {
+    println("File exists.")
+}
+```
+
+### `node.delete(path string) !`

+}
+```
+
+### File Transfers (`node.upload` and `node.download`)
+
+Transfer files between the local machine and the target node using `rsync` or `scp`.

+
+// Upload and execute a local V script on the remote node
+node.vscript(path: "/local/path/to/my_script.vsh", sync_from_local: true)!
+```
+
+## Port Forwarding
+
+The `portforward_to_local` function allows forwarding a remote port on an SSH host to a local port.
+
+```v
+import incubaid.herolib.builder { portforward_to_local, ForwardArgsToLocal }
+
+// Forward remote port 8080 on 192.168.1.100 to local port 9000
+portforward_to_local(
+    name: "my_app_forward",
+    address: "192.168.1.100",
+    remote_port: 8080,

+# OurTime Module
+
+The `OurTime` module in V provides flexible time handling, supporting relative and absolute time formats, Unix timestamps, and formatting utilities.
+
+## Key Features
+
+- Create time objects from strings or current time
+- Relative time expressions (e.g., `+1h`, `-2d`)
+- Absolute time formats (e.g., `YYYY-MM-DD HH:mm:ss`)
+- Unix timestamp conversion
+- Time formatting and warping
+
+## Basic Usage
+
+```v
+import incubaid.herolib.data.ourtime
+
+// Current time
+mut t := ourtime.now()
+
+// From string
+t2 := ourtime.new('2022-12-05 20:14:35')!
+
+// Get formatted string
+println(t2.str()) // e.g., 2022-12-05 20:14
+
+// Get Unix timestamp
+println(t2.unix()) // e.g., 1670271275
+```
+
+## Time Formats
+
+### Relative Time
+
+Use `s` (seconds), `h` (hours), `d` (days), `w` (weeks), `M` (months), `Q` (quarters), `Y` (years).
+
+```v
+// Create with relative time
+mut t := ourtime.new('+1w +2d -4h')!
+
+// Warp existing time
+mut t2 := ourtime.now()
+t2.warp('+1h')!
+```
+
+### Absolute Time
+
+Supports `YYYY-MM-DD HH:mm:ss`, `YYYY-MM-DD HH:mm`, `YYYY-MM-DD HH`, `YYYY-MM-DD`, `DD-MM-YYYY`.
+
+```v
+t1 := ourtime.new('2022-12-05 20:14:35')!
+t2 := ourtime.new('2022-12-05')! // Time defaults to 00:00:00
+```
+
+## Methods Overview
+
+### Creation
+
+```v
+now_time := ourtime.now()
+from_string := ourtime.new('2023-01-15')!
+from_epoch := ourtime.new_from_epoch(1673788800)
+```
+
+### Formatting
+
+```v
+mut t := ourtime.now()
+println(t.str()) // YYYY-MM-DD HH:mm
+println(t.day()) // YYYY-MM-DD
+println(t.key()) // YYYY_MM_DD_HH_mm_ss
+println(t.md())  // Markdown format
+```
+
+### Operations
+
+```v
+mut t := ourtime.now()
+t.warp('+1h')! // Move 1 hour forward
+unix_ts := t.unix()
+is_empty := t.empty()
+```
+
+## Error Handling
+
+Time parsing methods return a `Result` type and should be handled with `!` or `or` blocks.
+
+```v
+t_valid := ourtime.new('2023-01-01')!
+t_invalid := ourtime.new('bad-date') or {
+    println('Error: ${err}')
+    ourtime.now() // Fallback
+}

+# Herolib Spreadsheet Module for AI Prompt Engineering
+
+This document provides an overview and usage instructions for the `incubaid.herolib.biz.spreadsheet` module, which offers a powerful software representation of a spreadsheet. This module is designed for business modeling, data analysis, and can be leveraged in AI prompt engineering scenarios where structured data manipulation and visualization are required.
+
+## 1. Core Concepts
+
+The spreadsheet module revolves around three main entities: `Sheet`, `Row`, and `Cell`.
+
+### 1.1. Sheet
+
+The `Sheet` is the primary container, representing the entire spreadsheet.
+
+* **Properties:**
+  * `name` (string): A unique identifier for the sheet.
+  * `rows` (map[string]&Row): A collection of `Row` objects, indexed by their names.
+  * `nrcol` (int): The number of columns in the sheet (e.g., 60 for 5 years of monthly data).
+  * `params` (SheetParams): Configuration parameters, e.g., `visualize_cur` (boolean to display currency symbols).
+  * `currency` (currency.Currency): The default currency for the sheet (e.g., USD), used for automatic conversions.
+
+* **Creation:**
+
+    ```v
+    import incubaid.herolib.biz.spreadsheet
+
+    // Create a new sheet named 'my_financial_sheet' with 60 columns (e.g., 60 months)
+    mut my_sheet := spreadsheet.sheet_new(
+        name: 'my_financial_sheet',
+        nrcol: 60,
+        visualize_cur: true, // Optional: display currency symbols
+        curr: 'USD' // Optional: set default currency
+    )!
+
+    // Get an existing sheet from the global store
+    mut existing_sheet := spreadsheet.sheet_get('my_financial_sheet')!
+    ```
+
+* **Key Operations:**
+  * `sheet.row_get(name string) !&Row`: Retrieves a row by its name.
+  * `sheet.cell_get(row string, col int) !&Cell`: Retrieves a cell by row name and column index.
+  * `sheet.row_delete(name string)` / `sheet.delete(name string)`: Deletes a row.
+  * `sheet.cells_width(colnr int) !int`: Finds the maximum string length of cells in a given column.
+  * `sheet.rows_names_width_max() int`: Returns the maximum width of row names/aliases.
+  * `sheet.rows_description_width_max() int`: Returns the maximum width of row descriptions.
+  * `sheet.header() ![]string`: Generates column headers (e.g., "M1", "Q1", "Y1") based on `nrcol`.
+
+### 1.2. Row
+
+A `Row` represents a single horizontal line of data within a `Sheet`.
+
+* **Properties:**
+  * `name` (string): Unique identifier for the row.
+  * `alias` (string, optional): Alternative name.
+  * `description` (string): Textual description.
+  * `tags` (string): Space-separated tags for categorization (e.g., "department:hr location:belgium").
+  * `cells` ([]Cell): List of `Cell` objects.
+  * `aggregatetype` (RowAggregateType): Defines default aggregation for this row (`.sum`, `.avg`, `.max`, `.min`).
+
+* **Creation (within a Sheet):**
+
+    ```v
+    // Assuming 'my_sheet' is an existing Sheet object
+    mut salaries_row := my_sheet.row_new(
+        name: 'salaries',
+        tags: 'department:hr location:belgium',
+        descr: 'Monthly salaries for HR department in Belgium',
+        aggregatetype: .sum
+    )!
+    ```
+
+* **Key Operations:**
+  * `row.values_get() []f64`: Returns all cell values in the row as a list of floats.
+
+### 1.3. Cell
+
+A `Cell` is the fundamental unit of data, storing a numeric value.
+
+* **Properties:**
+  * `val` (f64): The numeric value.
+  * `empty` (bool): `true` if the cell is empty.
+
+* **Key Operations:**
+  * `cell.set(v string) !`: Sets the cell's value. Handles currency strings (e.g., "100 USD") by converting to the sheet's currency.
+  * `cell.add(v f64)`: Adds a numeric value to the existing cell value.
+  * `cell.repr() string`: Returns a formatted string representation of the value (e.g., "100.00", or "-" if empty).
+
+## 2. Data Aggregation and Transformation
+
+The module provides powerful tools for summarizing and transforming data.
+
+### 2.1. Grouping Rows (`group2row`)
+
+Aggregates selected rows into a new single row based on tags.
+
+```v
+// Aggregate rows tagged 'department:dev' or 'department:engineering' into a new row
+mut total_salaries_row := my_sheet.group2row(
+    name: 'total_dev_engineering_salaries',
+    include: ['department:dev', 'department:engineering'],
+    tags: 'summary:dev_eng',
+    descr: 'Total salaries for Development and Engineering departments',
+    aggregatetype: .sum // Can be .sum, .avg, .max, .min
+)!
+```
+
+### 2.2. Transforming Periodicity (`toyear`, `toquarter`)
+
+Creates new sheets with data aggregated into larger time periods.
+
+```v
+// Assuming 'monthly_sheet' has 60 columns (monthly data)
+mut monthly_sheet := spreadsheet.sheet_new(name: 'monthly_data', nrcol: 60)!
+// ... populate monthly_sheet
+
+// Create a new sheet 'yearly_data' with data aggregated by year
+mut yearly_sheet := monthly_sheet.toyear(
+    name: 'yearly_data',
+    namefilter: ['revenue_row', 'expenses_row'], // Optional: filter specific rows
+    includefilter: ['category:income'] // Optional: filter by tags
+)!
+
+// Create a new sheet 'quarterly_data' with data aggregated by quarter
+mut quarterly_sheet := monthly_sheet.toquarter(name: 'quarterly_data')!
+```
+
+## 3. Exporting Data
+
+Export sheet data to CSV format.
+
+### 3.1. Export to CSV (`export_csv`)
+
+```v
+import os
+
+// Export to a CSV file with default pipe '|' separator
+my_sheet.export_csv(path: '~/output.csv')!
+
+// Export with custom comma ',' separator and include empty cells
+csv_content_with_empty := my_sheet.export_csv(
+    path: '~/output_with_empty.csv',
+    separator: ',',
+    include_empty: true
+)!
+
+// Export to a string only (no file)
+csv_string := my_sheet.export_csv(path: '')!
+println(csv_string)
+```
+
+* **`ExportCSVArgs` Parameters:**
+  * `path` (string, optional): File path. Empty string returns content as string. `~` is expanded to home directory.
+  * `include_empty` (bool, optional, default: `false`): If `true`, empty cells are included.
+  * `separator` (string, optional, default: `'|'`): Delimiter character.
+
+## 4. Charting Capabilities
+
+Integrates with ECharts for data visualization. Charting functions return an `echarts.EChartsOption` object.
+
+### 4.1. Common Charting Parameters (`RowGetArgs`)
+
+Used across line, bar, and pie charts to specify data and presentation.
+
+* `rowname` (string, optional): Single row name or comma-separated list.
+* `namefilter` ([]string, optional): List of exact row names to include.
+* `includefilter` ([]string, optional): List of tags to include.
+* `excludefilter` ([]string, optional): List of tags to exclude.
+* `period_type` (PeriodType, optional): X-axis period (`.month`, `.quarter`, `.year`).
+* `aggregate` (bool, optional, default: `true`): Aggregate multiple matching rows.
+* `aggregatetype` (RowAggregateType, optional, default: `.sum`): Aggregation type.
+* `unit` (UnitType, optional): Data unit.
+* `title`, `title_sub` (string, optional): Chart titles.
+* `size` (string, optional): For pie charts, defines radius (e.g., "70%").
+* `rowname_show` (bool, optional, default: `true`): Show row name in legend.
+* `descr_show` (bool, optional, default: `false`): Show row description (overrides `rowname_show`).
+* `description` (string, optional): General chart description.
+
+### 4.2. Chart Types
+
+* **Line Chart (`line_chart`)**: Visualizes trends over time.
+
+    ```v
+    import incubaid.herolib.web.echarts // Required for EChartsOption type
+
+    line_chart_option := my_sheet.line_chart(
+        rowname: 'revenue_row,expenses_row',
+        period_type: .month,
+        title: 'Revenue vs. Expenses Over Time'
+    )!
+    ```
+
+* **Bar Chart (`bar_chart`)**: Compares discrete categories or values.
+
+    ```v
+    bar_chart_option := my_sheet.bar_chart(
+        rowname: 'profit_row',
+        period_type: .quarter,
+        title: 'Quarterly Profit'
+    )!
+    ```
+
+* **Pie Chart (`pie_chart`)**: Shows proportions of categories.
+
+    ```v
+    pie_chart_option := my_sheet.pie_chart(
+        rowname: 'budget_allocation_row',
+        period_type: .year,
+        title: 'Annual Budget Allocation',
+        size: '70%'
+    )!
+    ```
+
+This documentation should provide sufficient information for an AI to understand and utilize the `lib/biz/spreadsheet` module effectively for various data manipulation and visualization tasks.

+# HeroScript: Vlang Integration
+
+## HeroScript Structure
+
+HeroScript is a concise scripting language with the following structure:
+
+```heroscript
+!!actor.action_name
+ param1: 'value1'
+ param2: 'value with spaces'
+ multiline_description: '
+  This is a multiline description.
+  It can span multiple lines.
+  '
+ arg1 arg2 // Arguments without keys
+```
+
+Key characteristics:
+
+- **Actions**: Start with `!!`, followed by `actor.action_name` (e.g., `!!mailclient.configure`).
+- **Parameters**: Defined as `key:value`. Values can be quoted for spaces.
+- **Multiline Support**: Parameters like `description` can span multiple lines.
+- **Arguments**: Values without keys (e.g., `arg1`).
+
+## Processing HeroScript in Vlang
+
+HeroScript can be parsed into a `playbook.PlayBook` object, allowing structured access to actions and their parameters, this is used in most of the herolib modules, it allows configuration or actions in a structured way.
+
+```v
+import incubaid.herolib.core.playbook { PlayBook }
+import incubaid.herolib.ui.console
+
+pub fn play(mut plbook PlayBook) ! {
+
+ if plbook.exists_once(filter: 'docusaurus.define') {
+  mut action := plbook.get(filter: 'docusaurus.define')!
+  mut p := action.params
+  //example how we get parameters from the action see aiprompts/herolib_core/core_params.md for more details
+  path_build := p.get_default('path_build', '')!
+  path_publish := p.get_default('path_publish', '')!
+  reset := p.get_default_false('reset')
+  use_doctree := p.get_default_false('use_doctree')
+ }
+
+ // Process 'docusaurus.add' actions to configure individual Docusaurus sites
+ actions := plbook.find(filter: 'docusaurus.add')!
+ for action in actions {
+  mut p := action.params
+  //do more processing here
+ }
+}
+```
+
+For detailed information on parameter retrieval methods (e.g., `p.get()`, `p.get_int()`, `p.get_default_true()`), refer to `aiprompts/herolib_core/core_params.md`.

+# HTTPConnection Module
+
+The `HTTPConnection` module provides a robust HTTP client for Vlang, supporting JSON, custom headers, retries, and caching.
+
+## Key Features
+
+- Type-safe JSON methods
+- Custom headers
+- Retry mechanism
+- Caching
+- URL encoding
+
+## Basic Usage
+
+```v
+import incubaid.herolib.core.httpconnection
+
+// Create a new HTTP connection
+mut conn := httpconnection.new(
+    name: 'my_api_client'
+    url: 'https://api.example.com'
+    retry: 3 // Number of retries for failed requests
+    cache: true // Enable caching
+)!
+```
+
+## Integration with Management Classes
+
+To integrate `HTTPConnection` into a management class (e.g., `HetznerManager`), use a method to lazily initialize and return the connection:
+
+```v
+// Example: HetznerManager
+pub fn (mut h HetznerManager) connection() !&httpconnection.HTTPConnection {
+ mut c := h.conn or {
+  mut c2 := httpconnection.new(
+   name:  'hetzner_${h.name}'
+   url:   h.baseurl
+   cache: true
+   retry: 3
+  )!
+  c2.basic_auth(h.user, h.password)
+  c2
+ }
+ return c
+}
+```
+
+## Examples
+
+### GET Request with JSON Response
+
+```v
+struct User {
+    id    int
+    name  string
+    email string
+}
+
+user := conn.get_json_generic[User](
+    prefix: 'users/1'
+)!
+```
+
+### POST Request with JSON Data
+
+```v
+struct NewUserResponse {
+    id int
+    status string
+}
+
+new_user_resp := conn.post_json_generic[NewUserResponse](
+    prefix: 'users'
+    params: {
+        'name': 'Jane Doe'
+        'email': 'jane@example.com'
+    }
+)!
+```
+
+### Custom Headers
+
+Set default headers or add them per request:
+
+```v
+import net.http { Header }
+
+// Set default header
+conn.default_header = http.new_header(key: .authorization, value: 'Bearer your-token')
+
+// Add custom header for a specific request
+response := conn.get_json(
+    prefix: 'protected/resource'
+    header: http.new_header(key: .content_type, value: 'application/json')
+)!
+```
+
+### Error Handling
+
+Methods return a `Result` type for error handling:
+
+```v
+user := conn.get_json_generic[User](
+    prefix: 'users/1'
+) or {
+    println('Error fetching user: ${err}')
+    return
+}

+# OurTime Module
+
+The `OurTime` module in V provides flexible time handling, supporting relative and absolute time formats, Unix timestamps, and formatting utilities.
+
+## Key Features
+
+- Create time objects from strings or current time
+- Relative time expressions (e.g., `+1h`, `-2d`)
+- Absolute time formats (e.g., `YYYY-MM-DD HH:mm:ss`)
+- Unix timestamp conversion
+- Time formatting and warping
+
+## Basic Usage
+
+```v
+import incubaid.herolib.data.ourtime
+
+// Current time
+mut t := ourtime.now()
+
+// From string
+t2 := ourtime.new('2022-12-05 20:14:35')!
+
+// Get formatted string
+println(t2.str()) // e.g., 2022-12-05 20:14
+
+// Get Unix timestamp
+println(t2.unix()) // e.g., 1670271275
+```
+
+## Time Formats
+
+### Relative Time
+
+Use `s` (seconds), `h` (hours), `d` (days), `w` (weeks), `M` (months), `Q` (quarters), `Y` (years).
+
+```v
+// Create with relative time
+mut t := ourtime.new('+1w +2d -4h')!
+
+// Warp existing time
+mut t2 := ourtime.now()
+t2.warp('+1h')!
+```
+
+### Absolute Time
+
+Supports `YYYY-MM-DD HH:mm:ss`, `YYYY-MM-DD HH:mm`, `YYYY-MM-DD HH`, `YYYY-MM-DD`, `DD-MM-YYYY`.
+
+```v
+t1 := ourtime.new('2022-12-05 20:14:35')!
+t2 := ourtime.new('2022-12-05')! // Time defaults to 00:00:00
+```
+
+## Methods Overview
+
+### Creation
+
+```v
+now_time := ourtime.now()
+from_string := ourtime.new('2023-01-15')!
+from_epoch := ourtime.new_from_epoch(1673788800)
+```
+
+### Formatting
+
+```v
+mut t := ourtime.now()
+println(t.str()) // YYYY-MM-DD HH:mm
+println(t.day()) // YYYY-MM-DD
+println(t.key()) // YYYY_MM_DD_HH_mm_ss
+println(t.md())  // Markdown format
+```
+
+### Operations
+
+```v
+mut t := ourtime.now()
+t.warp('+1h')! // Move 1 hour forward
+unix_ts := t.unix()
+is_empty := t.empty()
+```
+
+## Error Handling
+
+Time parsing methods return a `Result` type and should be handled with `!` or `or` blocks.
+
+```v
+t_valid := ourtime.new('2023-01-01')!
+t_invalid := ourtime.new('bad-date') or {
+    println('Error: ${err}')
+    ourtime.now() // Fallback
+}

+# Parameter Parsing in Vlang
+
+This document details the `paramsparser` module, essential for handling parameters in HeroScript and other contexts.
+
+## Obtaining a `paramsparser` Instance
+
+```v
+import incubaid.herolib.data.paramsparser
+
+// Create new params from a string
+params := paramsparser.new("color:red size:'large' priority:1 enable:true")!
+
+// Or create an empty instance and add parameters programmatically
+mut params := paramsparser.new_params()
+params.set("color", "red")
+```
+
+## Parameter Formats
+
+The parser supports various input formats:
+
+1. **Key-value pairs**: `key:value`
+2. **Quoted values**: `key:'value with spaces'` (single or double quotes)
+3. **Arguments without keys**: `arg1 arg2` (accessed by index)
+4. **Comments**: `// this is a comment` (ignored during parsing)
+
+Example:
+
+```v
+text := "name:'John Doe' age:30 active:true // user details"
+params := paramsparser.new(text)!
+```

+# Pathlib Usage Guide
+
+## Overview
+
+The pathlib module provides a comprehensive interface for handling file system operations. Key features include:
+
+- Robust path handling for files, directories, and symlinks
+- Support for both absolute and relative paths
+- Automatic home directory expansion (~)
+- Recursive directory operations
+- Path filtering and listing
+- File and directory metadata access
+
+## Basic Usage
+
+### Importing pathlib
+
+```v
+import incubaid.herolib.core.pathlib
+```
+
+### Creating Path Objects
+
+This will figure out if the path is a dir, file and if it exists.
+
+```v
+// Create a Path object for a file
+mut file_path := pathlib.get("path/to/file.txt")
+
+// Create a Path object for a directory
+mut dir_path := pathlib.get("path/to/directory")
+```
+
+if you know in advance if you expect a dir or file its better to use `pathlib.get_dir(path:...,create:true)` or `pathlib.get_file(path:...,create:true)`.
+
+### Basic Path Operations
+
+```v
+// Get absolute path
+abs_path := file_path.absolute()
+
+// Get real path (resolves symlinks)
+real_path := file_path.realpath()
+
+// Check if path exists
+if file_path.exists() {
+    // Path exists
+}
+```
+
+## Path Properties and Methods
+
+### Path Types
+
+```v
+// Check if path is a file
+if file_path.is_file() {
+    // Handle as file
+}
+
+// Check if path is a directory
+if dir_path.is_dir() {
+    // Handle as directory
+}
+
+// Check if path is a symlink
+if file_path.is_link() {
+    // Handle as symlink
+}
+```
+
+### Path Normalization
+
+```v
+// Normalize path (remove extra slashes, resolve . and ..)
+normalized_path := file_path.path_normalize()
+
+// Get path directory
+dir_path := file_path.path_dir()
+
+// Get path name without extension
+name_no_ext := file_path.name_no_ext()
+```
+
+## File and Directory Operations
+
+### File Operations
+
+```v
+// Write to file
+file_path.write("Content to write")!
+
+// Read from file
+content := file_path.read()!
+
+// Delete file
+file_path.delete()!
+```
+
+### Directory Operations
+
+```v
+// Create directory
+mut dir := pathlib.get_dir(
+    path: "path/to/new/dir"
+    create: true
+)!
+
+// List directory contents
+mut dir_list := dir.list()!
+
+// Delete directory
+dir.delete()!
+```
+
+### Symlink Operations
+
+```v
+// Create symlink
+file_path.link("path/to/symlink", delete_exists: true)!
+
+// Resolve symlink
+real_path := file_path.realpath()
+```
+
+## Advanced Operations
+
+### Path Copying
+
+```v

+# Redisclient Module
+
+The `redisclient` module in Herolib provides a comprehensive client for interacting with Redis, supporting various commands, caching, queues, and RPC mechanisms.
+
+## Key Features
+
+- **Direct Redis Commands**: Access to a wide range of Redis commands (strings, hashes, lists, keys, etc.).
+- **Caching**: Built-in caching mechanism with namespace support and expiration.
+- **Queues**: Simple queue implementation using Redis lists.
+- **RPC**: Remote Procedure Call (RPC) functionality over Redis queues for inter-service communication.
+
+## Basic Usage
+
+To get a Redis client instance, use `redisclient.core_get()`. By default, it connects to `127.0.0.1:6379`. You can specify a different address and port using the `RedisURL` struct.
+
+```v
+import incubaid.herolib.core.redisclient
+
+// Connect to default Redis instance (127.0.0.1:6379)
+mut redis := redisclient.core_get()!
+
+// Or connect to a specific Redis instance
+// mut redis_url := redisclient.RedisURL{address: 'my.redis.server', port: 6380}
+// mut redis := redisclient.core_get(redis_url)!
+
+// Example: Set and Get a key
+redis.set('mykey', 'myvalue')!
+value := redis.get('mykey')!
+// assert value == 'myvalue'
+
+// Example: Check if a key exists
+exists := redis.exists('mykey')!
+// assert exists == true
+
+// Example: Delete a key
+redis.del('mykey')!
+```
+
+## Redis Commands
+
+The `Redis` object provides methods for most standard Redis commands. Here are some examples:
+
+### String Commands
+
+- `set(key string, value string) !`: Sets the string value of a key.
+- `get(key string) !string`: Gets the string value of a key.
+- `set_ex(key string, value string, ex string) !`: Sets a key with an expiration time in seconds.
+- `incr(key string) !int`: Increments the integer value of a key by one.
+- `decr(key string) !int`: Decrements the integer value of a key by one.
+- `append(key string, value string) !int`: Appends a value to a key.
+- `strlen(key string) !int`: Gets the length of the value stored in a key.
+
+```v
+redis.set('counter', '10')!
+redis.incr('counter')! // counter is now 11
+val := redis.get('counter')! // "11"
+```
+
+### Hash Commands
+
+- `hset(key string, skey string, value string) !`: Sets the string value of a hash field.
+- `hget(key string, skey string) !string`: Gets the value of a hash field.
+- `hgetall(key string) !map[string]string`: Gets all fields and values in a hash.
+- `hexists(key string, skey string) !bool`: Checks if a hash field exists.
+- `hdel(key string, skey string) !int`: Deletes one or more hash fields.
+
+```v
+redis.hset('user:1', 'name', 'John Doe')!
+redis.hset('user:1', 'email', 'john@example.com')!
+user_name := redis.hget('user:1', 'name')! // "John Doe"
+user_data := redis.hgetall('user:1')! // map['name':'John Doe', 'email':'john@example.com']
+```
+
+### List Commands
+
+- `lpush(key string, element string) !int`: Inserts all specified values at the head of the list stored at key.
+- `rpush(key string, element string) !int`: Inserts all specified values at the tail of the list stored at key.
+- `lpop(key string) !string`: Removes and returns the first element of the list stored at key.
+- `rpop(key string) !string`: Removes and returns the last element of the list stored at key.
+- `llen(key string) !int`: Gets the length of a list.
+- `lrange(key string, start int, end int) ![]resp.RValue`: Gets a range of elements from a list.
+
+```v
+redis.lpush('mylist', 'item1')!
+redis.rpush('mylist', 'item2')!
+first_item := redis.lpop('mylist')! // "item1"
+```
+
+### Set Commands
+
+- `sadd(key string, members []string) !int`: Adds the specified members to the set stored at key.
+- `smismember(key string, members []string) ![]int`: Returns if member is a member of the set stored at key.
+
+```v
+redis.sadd('myset', ['member1', 'member2'])!
+is_member := redis.smismember('myset', ['member1', 'member3'])! // [1, 0]
+```
+
+### Key Management
+
+- `keys(pattern string) ![]string`: Finds all keys matching the given pattern.
+- `del(key string) !int`: Deletes a key.
+- `expire(key string, seconds int) !int`: Sets a key's time to live in seconds.
+- `ttl(key string) !int`: Gets the time to live for a key in seconds.
+- `flushall() !`: Deletes all the keys of all the existing databases.
+- `flushdb() !`: Deletes all the keys of the currently selected database.
+- `selectdb(database int) !`: Changes the selected database.
+
+```v
+redis.set('temp_key', 'value')!
+redis.expire('temp_key', 60)! // Expires in 60 seconds
+```
+
+## Redis Cache
+
+The `RedisCache` struct provides a convenient way to implement caching using Redis.
+
+```v
+import incubaid.herolib.core.redisclient
+
+mut redis := redisclient.core_get()!
+mut cache := redis.cache('my_app_cache')
+
+// Set a value in cache with expiration (e.g., 3600 seconds)
+cache.set('user:profile:123', '{ "name": "Alice" }', 3600)!
+
+// Get a value from cache
+cached_data := cache.get('user:profile:123') or {
+    // Cache miss, fetch from source
+    println('Cache miss for user:profile:123')
+    return
+}
+// println('Cached data: ${cached_data}')
+
+// Check if a key exists in cache
+exists := cache.exists('user:profile:123')
+// assert exists == true
+
+// Reset the cache for the namespace
+cache.reset()!
+```
+
+## Redis Queue
+
+The `RedisQueue` struct provides a simple queue mechanism using Redis lists.
+
+```v
+import incubaid.herolib.core.redisclient
+import time
+
+mut redis := redisclient.core_get()!
+mut my_queue := redis.queue_get('my_task_queue')
+
+// Add items to the queue
+my_queue.add('task1')!
+my_queue.add('task2')!
+
+// Get an item from the queue with a timeout (e.g., 1000 milliseconds)
+task := my_queue.get(1000)!
+// assert task == 'task1'
+
+// Pop an item without timeout (returns error if no item)
+task2 := my_queue.pop()!
+// assert task2 == 'task2'
+```
+
+## Redis RPC
+
+The `RedisRpc` struct enables Remote Procedure Call (RPC) over Redis, allowing services to communicate by sending messages to queues and waiting for responses.
+
+```v
+import incubaid.herolib.core.redisclient
+import json
+import time
+
+mut redis := redisclient.core_get()!
+mut rpc_client := redis.rpc_get('my_rpc_service')
+
+// Define a function to process RPC requests (server-side)
+fn my_rpc_processor(cmd string, data string) !string {
+    // Simulate some processing based on cmd and data
+    return 'Processed: cmd=${cmd}, data=${data}'
+}
+
+// --- Client Side (calling the RPC) ---
+// Call the RPC service
+response := rpc_client.call(
+    cmd: 'greet',
+    data: '{"name": "World"}',
+    wait: true,
+    timeout: 5000 // 5 seconds timeout
+)!
+// println('RPC Response: ${response}')
+// assert response == 'Processed: cmd=greet, data={"name": "World"}'
+
+// --- Server Side (processing RPC requests) ---
+// In a separate goroutine or process, you would run:
+// rpc_client.process(my_rpc_processor, timeout: 0)! // timeout 0 means no timeout, keeps processing
+
+// Example of how to process a single request (for testing/demonstration)
+// In a real application, this would be in a loop or a background worker
+// return_queue_name := rpc_client.process(my_rpc_processor, timeout: 1000)!
+// result := rpc_client.result(1000, return_queue_name)!
+// println('Processed result: ${result}')

+V allows for easily using text templates, expanded at compile time to
+V functions, that efficiently produce text output. This is especially
+useful for templated HTML views, but the mechanism is general enough
+to be used for other kinds of text output also.
+
+# Template directives
+
+Each template directive begins with an `@` sign.
+Some directives contain a `{}` block, others only have `''` (string) parameters.
+
+Newlines on the beginning and end are ignored in `{}` blocks,
+otherwise this (see [if](#if) for this syntax):
+
+```html
+@if bool_val {
+    <span>This is shown if bool_val is true</span>
+}
+```
+
+... would output:
+
+```html
+
+    <span>This is shown if bool_val is true</span>
+
+```
+
+... which is less readable.
+
+## if
+
+The if directive, consists of three parts, the `@if` tag, the condition (same syntax like in V)
+and the `{}` block, where you can write html, which will be rendered if the condition is true:
+
+```
+@if <condition> {}
+```
+
+### Example
+
+```html
+@if bool_val {
+    <span>This is shown if bool_val is true</span>
+}
+```
+
+One-liner:
+
+```html
+@if bool_val { <span>This is shown if bool_val is true</span> }
+```
+
+The first example would result in:
+
+```html
+    <span>This is shown if bool_val is true</span>
+```
+
+... while the one-liner results in:
+
+```html
+<span>This is shown if bool_val is true</span>
+```
+
+## for
+
+The for directive consists of three parts, the `@for` tag,
+the condition (same syntax like in V) and the `{}` block,
+where you can write text, rendered for each iteration of the loop:
+
+```
+@for <condition> {}
+```
+
+### Example for @for
+
+```html
+@for i, val in my_vals {
+    <span>$i - $val</span>
+}
+```
+
+One-liner:
+
+```html
+@for i, val in my_vals { <span>$i - $val</span> }
+```
+
+The first example would result in:
+
+```html
+    <span>0 - "First"</span>
+    <span>1 - "Second"</span>
+    <span>2 - "Third"</span>
+    ...
+```
+
+... while the one-liner results in:
+
+```html
+<span>0 - "First"</span>
+<span>1 - "Second"</span>
+<span>2 - "Third"</span>
+...
+```
+
+You can also write (and all other for condition syntaxes that are allowed in V):
+
+```html
+@for i = 0; i < 5; i++ {
+    <span>$i</span>
+}
+```
+
+## include
+
+The include directive is for including other html files (which will be processed as well)
+and consists of two parts, the `@include` tag and a following `'<path>'` string.
+The path parameter is relative to the template file being called.
+
+### Example for the folder structure of a project using templates:
+
+```
+Project root
+/templates
+    - index.html
+    /headers
+        - base.html
+```
+
+`index.html`
+
+```html
+
+<div>@include 'header/base'</div>
+```
+
+> Note that there shouldn't be a file suffix,
+> it is automatically appended and only allows `html` files.
+
+
+## js
+
+The js directive consists of two parts, the `@js` tag and `'<path>'` string,
+where you can insert your src
+
+```
+@js '<url>'
+```
+
+### Example for the @js directive:
+
+```html
+@js 'myscripts.js'
+```
+
+# Variables
+
+All variables, which are declared before the $tmpl can be used through the `@{my_var}` syntax.
+It's also possible to use properties of structs here like `@{my_struct.prop}`.
+
+# Escaping
+
+The `@` symbol starts a template directive. If you need to use `@` as a regular 
+character within a template, escape it by using a double `@` like this: `@@`.

+
+## Model Structure Overview
+
+Each model in the HeroModels system consists of several components:
+
+1. **Model Struct**: The core data structure inheriting from `db.Base`
+2. **DB Wrapper Struct**: Provides database operations for the model
+3. **Argument Struct**: Used for creating and updating model instances
+4. **API Handler Function**: Handles RPC calls for the model
+5. **List Arguments Struct**: Used for filtering when listing instances
+
+### Directory Structure
+
+```
+lib/hero/heromodels/
+  ├── model_name.v         # Main model file
+  ├── model_name_test.v    # Tests for the model
+  └── factory.v            # Factory integration
+```
+
+## Creating a New Model
+
+### 1. Define the Model Struct
+
+Create a new file `model_name.v` in the `lib/hero/heromodels` directory.
+
+```v
+module heromodels
+
+import incubaid.herolib.core.db
+import incubaid.herolib.core.encoder
+import incubaid.herolib.core.ourtime
+import incubaid.herolib.core.jsonrpc { Response }
+import json
+
+// Model struct - inherits from db.Base
+pub struct ModelName {
+pub mut:
+    db.Base       // Inherit from db.Base
+    name         string
+    description  string
+    created_at   u64
+    updated_at   u64
+    // Add additional fields as needed
+}
+
+// TypeName returns the type name used for serialization
+pub fn (self ModelName) type_name() string {
+    return 'heromodels.ModelName'
+}
+```
+
+### 2. Define the Argument Struct for Model Creation/Updates
+
+```v
+// Argument struct for creating/updating models with params attribute
+@[params]
+pub struct ModelNameArg {
+pub mut:
+    id           u32     // Optional for updates, ignored for creation
+    name         string  @[required] // Required field
+    description  string
+    // Add additional fields as needed
+}
+```
+
+### 3. Define the List Arguments Struct for Filtering
+
+```v
+// Arguments for filtering when listing models
+@[params]
+pub struct ModelNameListArg {
+pub mut:
+    // Add filter fields (e.g., status, type, etc.)
+    limit        int = 100 // Default limit
+}
+```
+
+### 4. Create the DB Wrapper Struct
+
+```v
+// DB Wrapper struct for database operations
+pub struct DBModelName {
+pub mut:
+    db &db.DB
+}
+```
+
+## Serialization and Deserialization
+
+Implement the `dump` and `load` methods for serialization/deserialization.
+
+### Dump Method (Serialization)
+
+```v
+// Dump serializes the model to the encoder
+pub fn (self ModelName) dump(mut e encoder.Encoder) ! {
+    // Always dump the Base first
+    self.Base.dump(mut e)!
+    
+    // Dump model-specific fields in the same order they will be loaded
+    e.add_string(self.name)!
+    e.add_string(self.description)!
+    e.add_u64(self.created_at)!
+    e.add_u64(self.updated_at)!
+    // Add more fields in the exact order they should be loaded
+}
+```
+
+### Load Method (Deserialization)
+
+```v
+// Load deserializes the model from the decoder
+pub fn (mut self DBModelName) load(mut obj ModelName, mut d encoder.Decoder) ! {
+    // Always load the Base first
+    obj.Base.load(mut d)!
+    
+    // Load model-specific fields in the same order they were dumped
+    obj.name = d.get_string()!
+    obj.description = d.get_string()!
+    obj.created_at = d.get_u64()!
+    obj.updated_at = d.get_u64()!
+    // Add more fields in the exact order they were dumped
+}
+```
+
+## Database Operations
+
+Implement the standard CRUD operations and additional methods.
+
+### New Instance Creation
+
+```v
+// Create a new model instance from arguments
+pub fn (mut self DBModelName) new(args ModelNameArg) !ModelName {
+    mut o := ModelName{
+        name: args.name
+        description: args.description
+        // Initialize other fields
+        created_at: ourtime.now().unix()
+        updated_at: ourtime.now().unix()
+    }
+    
+    // Additional initialization logic
+    
+    return o
+}
+```
+
+### Set (Create or Update)
+
+```v
+// Save or update a model instance
+pub fn (mut self DBModelName) set(o ModelName) !ModelName {
+    return self.db.set[ModelName](o)!
+}
+```
+
+### Get
+
+```v
+// Retrieve a model instance by ID
+pub fn (mut self DBModelName) get(id u32) !ModelName {
+    mut o, data := self.db.get_data[ModelName](id)!
+    mut e_decoder := encoder.decoder_new(data)
+    self.load(mut o, mut e_decoder)!
+    return o
+}
+```
+
+### Delete
+
+```v
+// Delete a model instance by ID
+pub fn (mut self DBModelName) delete(id u32) !bool {
+    // Check if the item exists before trying to delete
+    if !self.db.exists[ModelName](id)! {
+        return false
+    }
+    self.db.delete[ModelName](id)!
+    return true
+}
+```
+
+### Exist
+
+```v
+// Check if a model instance exists by ID
+pub fn (mut self DBModelName) exist(id u32) !bool {
+    return self.db.exists[ModelName](id)!
+}
+```
+
+### List with Filtering
+
+```v
+// List model instances with optional filtering
+pub fn (mut self DBModelName) list(args ModelNameListArg) ![]ModelName {
+    // Get all instances
+    all_items := self.db.list[ModelName]()!.map(self.get(it)!)
+    
+    // Apply filters
+    mut filtered_items := []ModelName{}
+    for item in all_items {
+        // Apply your filter conditions here
+        // Example:
+        // if args.some_filter && item.some_property != args.filter_value {
+        //     continue
+        // }
+        
+        filtered_items << item
+    }
+    
+    // Apply limit
+    mut limit := args.limit
+    if limit > 100 {
+        limit = 100
+    }
+    if filtered_items.len > limit {
+        return filtered_items[..limit]
+    }
+    
+    return filtered_items
+}
+```
+
+## API Handler Implementation
+
+Create the handler function for RPC requests.
+
+```v
+// Handler for RPC calls to this model
+pub fn model_name_handle(mut f ModelsFactory, rpcid int, servercontext map[string]string, userref UserRef, method string, params string) !Response {
+    match method {
+        'get' {
+            id := db.decode_u32(params)!
+            res := f.model_name.get(id)!
+            return new_response(rpcid, json.encode_pretty(res))
+        }
+        'set' {
+            mut args := db.decode_generic[ModelNameArg](params)!
+            mut o := f.model_name.new(args)!
+            if args.id != 0 {
+                o.id = args.id
+            }
+            o = f.model_name.set(o)!
+            return new_response_int(rpcid, int(o.id))
+        }
+        'delete' {
+            id := db.decode_u32(params)!
+            deleted := f.model_name.delete(id)!
+            if deleted {
+                return new_response_true(rpcid)
+            } else {
+                return new_error(rpcid,
+                    code:    404
+                    message: 'ModelName with ID ${id} not found'
+                )
+            }
+        }
+        'exist' {
+            id := db.decode_u32(params)!
+            if f.model_name.exist(id)! {
+                return new_response_true(rpcid)
+            } else {
+                return new_response_false(rpcid)
+            }
+        }
+        'list' {
+            args := db.decode_generic[ModelNameListArg](params)!
+            res := f.model_name.list(args)!
+            return new_response(rpcid, json.encode_pretty(res))
+        }
+        else {
+            return new_error(rpcid,
+                code:    32601
+                message: 'Method ${method} not found on model_name'
+            )
+        }
+    }
+}
+```
+
+## Testing Models
+
+Create a `model_name_test.v` file to test your model.
+
+```v

+    assert retrieved_model.name == 'Encoding Test'
+    assert retrieved_model.description == 'Testing encoding/decoding'
+    // Check other fields
+}
+```
+
+## Integration with Factory
+
+Update the `factory.v` file to include your new model.
+
+### 1. Add the Model to the Factory Struct
+
+```v
+// In factory.v
+pub struct ModelsFactory {
+pub mut:
+    db                &db.DB
+    user              DBUser
+    group             DBGroup
+    // Add your new model
+    model_name        DBModelName
+    // Other models...
+    rpc_handler       &jsonrpc.Handler
+}
+```
+
+### 2. Initialize the Model in the Factory New Method
+
+```v
+// In factory.v, in the new() function
+pub fn new(args ModelsFactoryArgs) !&ModelsFactory {
+    // Existing code...
+    
+    mut f := ModelsFactory{
+        db: &mydb
+        user: DBUser{
+            db: &mydb
+        }
+        // Add your new model
+        model_name: DBModelName{
+            db: &mydb
+        }
+        // Other models...
+        rpc_handler: &h
+    }
+    
+    // Existing code...
+}
+```
+
+### 3. Add Handler Registration to the Factory API Handler
+
+```v
+// In factory.v, in the group_api_handler function
+pub fn group_api_handler(rpcid int, servercontext map[string]string, actorname string, methodname string, params string) !jsonrpc.Response {
+    // Existing code...
+    
+    match actorname {
+        // Existing cases...
+        
+        'model_name' {
+            return model_name_handle(mut f, rpcid, servercontext, userref, methodname, params)!
+        }
+        
+        // Existing cases...
+        
+        else {
+            // Error handling
+        }
+    }
+}
+```
+
+## Advanced Features
+
+### Custom Methods
+
+You can add custom methods to your model for specific business logic:
+
+```v
+// Add a custom method to the model
+pub fn (mut self ModelName) custom_operation(param string) !string {
+    // Custom business logic
+    self.updated_at = ourtime.now().unix()
+    return 'Performed ${param} operation'
+}
+```
+
+### Enhanced RPC Handling
+
+Extend the RPC handler to support your custom methods:
+
+```v
+// In the model_name_handle function
+match method {
+    // Standard CRUD methods...
+    
+    'custom_operation' {
+        id := db.decode_u32(params)!
+        mut model := f.model_name.get(id)!
+        
+        // Extract parameter from JSON
+        param_struct := json.decode(struct { param string }, params) or {
+            return new_error(rpcid,
+                code:    32602
+                message: 'Invalid parameters for custom_operation'
+            )
+        }
+        
+        result := model.custom_operation(param_struct.param)!
+        model = f.model_name.set(model)! // Save changes
+        return new_response(rpcid, json.encode(result))
+    }
+    
+    else {
+        // Error handling
+    }
+}
+```
+
+## Best Practices
+
+1. **Field Order**: Keep field ordering consistent between `dump` and `load` methods
+2. **Error Handling**: Use the `!` operator consistently for error propagation
+3. **Timestamp Management**: Initialize timestamps using `ourtime.now().unix()`
+4. **Required Fields**: Mark mandatory fields with `@[required]` attribute
+5. **Limits**: Enforce list limits (default 100)
+6. **ID Handling**: Always check existence before operations like delete
+7. **Validation**: Add validation in the `new` and `set` methods
+8. **API Methods**: Implement the standard CRUD operations (get, set, delete, exist, list)
+9. **Comments**: Document all fields and methods
+10. **Testing**: Create comprehensive tests covering all methods
+

+# Instructions Archive (Legacy Prompts)
+
+This directory contains **archived / legacy AI prompt material** for `herolib`.
+
+- Files here may describe **older workflows** (e.g. previous documentation generation or model pipelines).
+- They are kept for **historical reference** and to help understand how things evolved.
+- They are **not** guaranteed to match the current `herolib` implementation.
+
+## Usage Guidelines
+
+- Do **not** use these files as the primary source for new features or refactors.
+- When generating code or documentation, prefer:
+  1. Code and module docs under `lib/` (e.g. `lib/web/site/ai_instructions.md`, `lib/web/docusaurus/README.md`).
+  2. Up-to-date AI instructions under `aiprompts/` (outside of `instructions_archive/`).
+- Only consult this directory when you explicitly need to understand **historical behavior** or migrate old flows.

+## INTENT
+
+we use heroscript to communicate actions and events in a structured format.
+we want you to parse user intents and generate the corresponding heroscript.
+
+ONLY RETURN THE HEROSCRIPT STATEMENTS, can be more than 1
+
+## HEROSCRIPT FORMAT
+
+HeroScript is a concise scripting language with the following structure:
+
+```heroscript
+!!actor.action_name
+	param1: 'value1'
+	param2: 'value with spaces'
+	multiline_description: '
+		This is a multiline description.
+		It can span multiple lines.
+		'
+	arg1 arg2 // Arguments without keys
+
+!!actor.action_name2 param1:something param2:'something with spaces' nr:3
+```
+
+Key characteristics:
+
+- **Actions**: Start with `!!`, followed by `actor.action_name` (e.g., `!!mailclient.configure`).
+- **Parameters**: Defined as `key:value`. Values can be quoted for spaces.
+- **Multiline Support**: Parameters like `description` can span multiple lines.
+- **Arguments**: Values without keys (e.g., `arg1`).
+- params can be on 1 line, with spaces in between
+- time can be as +1h, +1d, +1w (hour, day, week), ofcourse 1 can be any number, +1 means 1 hour from now
+- time format is:  dd/mm/yyyy hh:mm (ONLY USE THIS)
+- comma separation is used a lot in arguments e.g. 'jan,kristof' or 'jan , kristof' remove spaces, is list of 2
+- note only !! is at start of line, rest has spaces per instruction
+- make one empty line between 1 heroscript statements
+- everything after // is comment
+
+## HEROSCRIPT SCHEMA
+
+the language we understand
+
+### calendar management
+
+```heroscript 
+!!calendar.create when:'+1h'  descr:'this is event to discuss eng' attendees:'jan,kristof' name:'meet1' tags:'eng,urgent'
+!!calendar.delete name:'meet1'
+!!calendar.list tags:'urgent'
+
+```
+
+### contact management
+
+```heroscript 
+!!contact.add name:'jan' email:'jan@example.com' phone:'123-456-7890'
+!!contact.remove name:'jan'
+!!contact.list
+
+```
+
+### task management
+
+```heroscript 
+!!task.create title:'Prepare presentation' due:'+1d' assignee:'jan' name:'task1'  tags:'eng,urgent'
+	deadline:'+10d' duration:'1h'
+!!task.update name:'task1' status:'in progress'
+!!task.delete name:'task1'

+!!project.update name:'cloud_prod' status:'in progress'
+!!project.delete name:'cloud_prod'

+!!project.tasks_add names:'task1, task2'
+!!project.tasks_remove names:'task1, task2'
+
+```
+
+### SUPPORTED TAGS
+
+only tags supported are: 
+
+- for intent: eng, prod, support, mgmt, marketing
+- for urgency: urgent, high, medium, low
+
+### generic remarks
+
+- names are lowercase and snake_case, can be distilled out of title if only title given, often a user will say name but that means title
+- time: format of returned data or time is always dd/mm/yyyy hh:min
+
+## IMPORTANT STARTING INFO
+
+- current time is  10/08/2025 05:10 , use this to define any time-related parameters
+
+## USER INTENT

+SYSTEM
+You are a HeroScript compiler. Convert user intents into valid HeroScript statements.
+
+OUTPUT RULES
+
+1) Return ONLY HeroScript statements. No prose, no backticks.
+2) Separate each statement with exactly ONE blank line.
+3) Keys use snake_case. Names are lowercase snake_case derived from titles (non-alnum → "_", collapse repeats, trim).
+4) Lists are comma-separated with NO spaces (e.g., "jan,alex").
+5) Times: OUTPUT MUST BE ABSOLUTE in "dd/mm/yyyy hh:mm" (Europe/Zurich). Convert relative times (e.g., "tomorrow 10am") using CURRENT_TIME.
+6) Tags: include at most one intent tag and at most one urgency tag when present.
+   - intent: eng,prod,support,mgmt,marketing
+   - urgency: urgent,high,medium,low
+7) Quotes: quote values containing spaces; otherwise omit quotes (allowed either way).
+8) Comments only with // if the user explicitly asks for explanations; otherwise omit.
+
+SCHEMA (exact actions & parameters)
+
+!!calendar.create when:'dd/mm/yyyy hh:mm' name:'<name>' descr:'<text>' attendees:'a,b,c' tags:'intent,urgency'
+!!calendar.delete name:'<name>'

+!!project.tasks_remove name:'<project_name>' names:'task_a,task_b'
+
+NORMALIZATION & INFERENCE (silent)
+- Derive names from titles when missing (see rule 3). Ensure consistency across statements.
+- Map phrases to tags when obvious (e.g., "new product" ⇒ intent: prod; "high priority" ⇒ urgency: high).
+- Attendees: split on commas, trim, lowercase given names.
+- If the user asks for “urgent meetings,” use tags:'urgent' specifically.
+- Prefer concise descriptions pulled from the user’s phrasing.
+- Name's are required, if missing ask for clarification.
+- For calendar management, ensure to include all relevant details such as time, attendees, and description.

+## INSTRUCTIONS
+
+the user will send me multiple instructions what they wants to do, I want you to put them in separate categories
+
+The categories we have defined are:
+
+- calendar management
+  - schedule meetings, events, reminders
+  - list these events
+  - delete them
+- contact management
+  - add/remove contact information e.g. phone numbers, email addresses, address information
+  - list contacts, search
+- task or project management
+  - anything we need to do, anything we need to track and plan
+  - create/update tasks, set deadlines
+  - mark tasks as complete
+  - delete tasks
+  - project management
+- communication (chat, email)
+  - see what needs to be communicate e.g. send a chat to ... 
+- search statements
+  - find on internet, find specific information from my friends
+
+I want you to detect the intent and make multiple blocks out of the intent, each block should correspond to one of the identified intents, identify the intent with name of the category eg. calendar, only use above names
+
+
+
+what user wants to do, stay as close as possible to the original instructions, copy the exact instructions as where given by the user, we only need to sort the instructions in these blocks
+
+for each instruction make a separate block, e.g. if 2 tasks are given, create 2 blocks
+
+the format to return is: (note newline after each title of block)
+
+```template
+===CALENDAR===\n
+
+$the copied text from what user wants
+
+===CONTACT===\n
+...
+
+===QUESTION===\n
+
+put here what our system needs to ask to the user anything which is not clear
+
+===END===\n
+
+```
+
+I want you to execute above on instructions as given by user below, give text back ONLY supporting the template
+
+note for format is only ===$NAME=== and then on next lines the original instructions from the user, don't change
+
+## special processing of info
+
+- if a date or time specified e.g. tomorrow, time, ... calculate back from current date
+
+## IMPORTANT STARTING INFO
+
+- current time is  10/08/2025 05:10  (format of returned data is always dd/mm/yyyy hh:min)
+    - use the current time to define formatted time out of instructions
+    - only return the formatted time
+
+## UNCLEAR INFO
+
+check in instructions e.g. things specified like you, me, ... 
+are not clear ask specifically who do you mean
+
+if task, specify per task, who needs to do it and when, make sure each instruction (block) is complete and clear for further processing
+
+be very specific with the questions e.g. who is you, ...
+
+## EXECUTE ABOVE ON THE FOLLOWING
+
+I am planning a birthday for my daughters tomorrow, there will be 10 people.
+
+I would like to know if you can help me with the preparations.
+
+I need a place for my daughter's birthday party.
+
+I need to send message to my wife isabelle that she needs to pick up the cake.

-## heroscript
-
-Heroscript is our small scripting language which has following structure
-
-an example of a heroscript is
-
-```heroscript
-
-!!dagu.script_define
-	name: 'test_dag'
-	homedir:''
-	title:'a title'
-	reset:1
-	start:true //trie or 1 is same
-	colors: 'green,red,purple' //lists are comma separated
-	description: '
-		a description can be multiline
-
-		like this
-		'
-
-
-!!dagu.add_step
-	dag: 'test_dag'
-	name: 'hello_world'
-	command: 'echo hello world'
-
-!!dagu.add_step
-	dag: 'test_dag'
-	name: 'last_step'
-	command: 'echo last step'
-
-
-```
-
-Notice how:
-- every action starts with !!
-	- the first part is the actor e.g. dagu in this case
-	- the 2e part is the action name
-- multilines are supported see the description field
-
-## how to process heroscript in Vlang
-
-- heroscript can be converted to a struct,
-- the methods available to get the params are in 'params' section further in this doc

+# Unpoly API – Complete Reference & Operational Guide for AI Coding Agents
+
+## Introduction
+
+This document serves as a complete, self-contained reference manual for the **Unpoly JavaScript API**. It is written explicitly for AI coding agents that need to generate, validate, or refactor Unpoly-enhanced HTML and JavaScript code.
+
+Unpoly is a front-end framework for progressive enhancement. It allows HTML pages to update fragments instead of reloading the full document, enabling seamless transitions, modals, caching, and navigation while maintaining server-side rendering.
+
+An AI agent should use this manual to:
+- Understand each Unpoly module and its purpose.
+- Generate correct `up-*` attributes and JavaScript calls.
+- Detect configuration errors and provide correction suggestions.
+- Apply Unpoly in automated scaffolding, validation, and optimization workflows.
+
+---
+
+## 1. The up.link Module
+
+### Purpose
+Handles Unpoly-enhanced navigation. Converts normal links into AJAX-based fragment updates rather than full-page reloads.
+
+### Core Concepts
+When a user clicks a link with certain attributes, Unpoly intercepts the event and fetches the new page in the background. It then replaces specified fragments in the current document with matching elements from the response.
+
+### Common Attributes
+
+| Attribute       | Description                                              |
+| --------------- | -------------------------------------------------------- |
+| `up-follow`     | Marks the link as handled by Unpoly. Usually implied.    |
+| `up-target`     | CSS selector identifying which fragment(s) to replace.   |
+| `up-method`     | Overrides HTTP method (e.g. `GET`, `POST`).              |
+| `up-params`     | Adds query parameters to the request.                    |
+| `up-headers`    | Adds or overrides HTTP headers.                          |
+| `up-layer`      | Determines which layer (page, overlay, modal) to update. |
+| `up-transition` | Defines animation during fragment replacement.           |
+| `up-cache`      | Enables caching of the response.                         |
+| `up-history`    | Controls browser history behavior.                       |
+
+### JavaScript API Methods
+- `up.link.isFollowable(element)` – Returns true if Unpoly will intercept the link.
+- `up.link.follow(element, options)` – Programmatically follow the link via Unpoly.
+- `up.link.preload(element, options)` – Preload the linked resource into the cache.
+
+### Agent Reasoning & Validation
+- Ensure that every `up-follow` element has a valid `up-target` selector.
+- Validate that target elements exist in both the current DOM and the server response.
+- Recommend `up-cache` for commonly visited links to improve performance.
+- Prevent using `target="_blank"` or `download` attributes with Unpoly links.
+
+### Example
+```html
+<a href="/profile" up-target="#main" up-transition="fade">View Profile</a>
+```
+
+---
+
+## 2. The up.form Module
+
+### Purpose
+Handles progressive enhancement for forms. Submissions happen via AJAX and update only specific fragments.
+
+### Core Attributes
+
+| Attribute        | Description                             |
+| ---------------- | --------------------------------------- |
+| `up-submit`      | Marks form to be submitted via Unpoly.  |
+| `up-target`      | Fragment selector to update on success. |
+| `up-fail-target` | Selector to update if submission fails. |
+| `up-validate`    | Enables live field validation.          |
+| `up-autosubmit`  | Submits automatically on change.        |
+| `up-disable-for` | Disables fields during request.         |
+| `up-enable-for`  | Enables fields after request completes. |
+
+### JavaScript API
+- `up.form.submit(form, options)` – Submit programmatically.
+- `up.validate(field, options)` – Trigger server validation.
+- `up.form.fields(form)` – Returns all input fields.
+
+### Agent Reasoning
+- Always ensure form has both `action` and `method` attributes.
+- Match `up-target` to an element existing in the rendered HTML.
+- For validation, ensure server supports `X-Up-Validate` header.
+- When generating forms, add `up-fail-target` to handle errors gracefully.
+
+### Example
+```html
+<form action="/update" method="POST" up-submit up-target="#user-info" up-fail-target="#form-errors">
+  <input name="email" up-validate required>
+  <button type="submit">Save</button>
+</form>
+```
+
+---
+
+## 3. The up.layer Module
+
+### Purpose
+Manages overlays, modals, and stacked layers of navigation.
+
+### Attributes
+
+| Attribute        | Description                                        |
+| ---------------- | -------------------------------------------------- |
+| `up-layer="new"` | Opens content in a new overlay.                    |
+| `up-size`        | Controls modal size (e.g., `small`, `large`).      |
+| `up-dismissable` | Allows overlay to close by clicking outside.       |
+| `up-history`     | Determines if the overlay updates browser history. |
+| `up-title`       | Sets overlay title.                                |
+
+### JavaScript API
+- `up.layer.open(options)` – Opens a new layer.
+- `up.layer.close(layer)` – Closes a given layer.
+- `up.layer.on(event, callback)` – Hooks into lifecycle events.
+
+### Agent Notes
+- Ensure `up-layer="new"` only used with valid targets.
+- For overlays, set `up-history="false"` unless explicitly required.
+- Auto-generate dismiss buttons with `up-layer-close`.
+
+### Example
+```html
+<a href="/settings" up-layer="new" up-size="large" up-target=".modal-content">Open Settings</a>
+```
+
+---
+
+## 4. The up.fragment Module
+
+### Purpose
+Handles low-level fragment rendering, preserving, replacing, and merging.
+
+### JavaScript API
+- `up.render(options)` – Replace fragment(s) with new content.
+- `up.fragment.config` – Configure defaults for rendering.
+- `up.fragment.get(target)` – Retrieve a fragment.
+
+### Example
+```js
+up.render({ target: '#main', url: '/dashboard', transition: 'fade' })
+```
+
+### Agent Notes
+- Ensure only fragment HTML is sent from server (not full document).
+- Use `preserve` for elements like forms where input state matters.
+
+---
+
+## 5. The up.network Module
+
+### Purpose
+Handles network requests, caching, and aborting background loads.
+
+### JavaScript API
+- `up.network.loadPage(url, options)` – Load a page via Unpoly.
+- `up.network.abort()` – Abort ongoing requests.
+- `up.network.config.timeout` – Default timeout setting.
+
+### Agent Tasks
+- Preload probable links (`up.link.preload`).
+- Use caching for frequent calls.
+- Handle `up:network:late` event to show spinners.
+
+---
+
+## 6. The up.event Module
+
+### Purpose
+Manages custom events fired throughout Unpoly’s lifecycle.
+
+### Common Events
+- `up:link:follow`
+- `up:form:submit`
+- `up:layer:open`
+- `up:layer:close`
+- `up:rendered`
+- `up:network:late`
+
+### Example
+```js
+up.on('up:layer:close', (event) => {
+  console.log('Overlay closed');
+});
+```
+
+### Agent Actions
+- Register listeners for key events.
+- Prevent duplicate bindings.
+- Offer analytics hooks for `up:rendered` or `up:location:changed`.
+
+---
+
+## 7. The up.motion Module
+
+Handles animations and transitions.
+
+### API
+- `up.motion()` – Animate elements.
+- `up.animate(element, keyframes, options)` – Custom animation.
+
+### Agent Notes
+- Suggest `up-transition="fade"` or similar for fragment changes.
+- Avoid heavy animations for performance-sensitive devices.
+
+---
+
+## 8. The up.radio Module
+
+Handles broadcasting and receiving cross-fragment events.
+
+### Example
+```js
+up.radio.emit('user:updated', { id: 5 })
+up.radio.on('user:updated', (data) => console.log(data))
+```
+
+### Agent Tasks
+- Use for coordinating multiple fragments.
+- Ensure channel names are namespaced (e.g., `form:valid`, `modal:open`).
+
+---
+
+## 9. The up.history Module
+
+### Purpose
+Manages URL history, titles, and restoration.
+
+### API
+- `up.history.push(url, options)` – Push new history entry.
+- `up.history.restore()` – Restore previous state.
+
+### Agent Guidance
+- Disable history (`up-history="false"`) for temporary overlays.
+- Ensure proper title update via `up-title`.
+
+---
+
+## 10. The up.viewport Module
+
+### Purpose
+Manages scrolling, focusing, and viewport restoration.
+
+### API
+- `up.viewport.scroll(element)` – Scroll to element.
+- `up.viewport.restoreScroll()` – Restore previous position.
+
+### Agent Tasks
+- Restore scroll after fragment updates.
+- Manage focus for accessibility after `up.render()`.
+
+---
+
+## 11. The up.protocol Module
+
+Handles request headers and special HTTP status codes.
+
+### Key Concepts
+- Adds `X-Up-Target` and `X-Up-Validate` headers.
+- Interprets redirect and validation responses.
+
+### Agent Notes
+- Ensure backend supports Unpoly headers.
+- Warn if 204 or redirect status used without fragments.
+
+---
+
+## 12. The up.util Module
+
+Contains helpers for arrays, strings, and timing.
+
+### Examples
+```js
+up.util.escapeHTML("<script>") // "&lt;script&gt;"
+up.util.copy(text)
+```
+
+### Agent Tasks
+- Use helpers for DOM-safe generation.
+- Avoid reimplementing basic utilities.
+
+---
+
+## 13. The up.framework and up.log Modules
+
+- `up.framework.init()` – Initializes Unpoly.
+- `up.log.enable()` – Enables debug logging.
+
+### Agent Tasks
+- Always call `up.framework.init()` once.
+- Enable logging during debug sessions.
+
+---
+
+Good addition — including **Unpoly from a CDN** is essential for setup and automation.
+Here’s the section you can append to the Markdown file (I can also regenerate the full file with it included if you prefer):

+
+## 14. Including Unpoly from CDN
+
+### Purpose
+
+Before any Unpoly features or attributes (`up-*`) can work, the library must be loaded into the page.
+For AI agents generating HTML pages or templates, always include Unpoly’s **CSS** and **JavaScript** assets early in the `<head>` section.
+
+### Basic Setup (Latest Stable Version)
+
+```html
+<!DOCTYPE html>
+<html>
+<head>
+  <meta charset="utf-8">
+  <title>My Unpoly Page</title>
+
+  <!-- Unpoly Core Styles -->
+  <link rel="stylesheet" href="https://unpkg.com/unpoly@3.7.2/unpoly.min.css">
+
+  <!-- Optional Bootstrap integration -->
+  <link rel="stylesheet" href="https://unpkg.com/unpoly@3.7.2/unpoly-bootstrap3.min.css">
+
+  <!-- Unpoly Core Script -->
+  <script src="https://unpkg.com/unpoly@3.7.2/unpoly.min.js"></script>
+
+  <!-- Initialize framework -->
+  <script>
+    up.framework.init()
+  </script>
+</head>
+<body>
+  <!-- Page content -->
+</body>
+</html>
+```
+
+### AI Agent Notes
+
+* Always include **`unpoly.min.css`** before any custom styles to ensure default animations and transitions function properly.
+* **Never** load Unpoly twice; check if the page already has a `<script src="...unpoly.min.js">`.
+* After loading, the agent may immediately use Unpoly JavaScript APIs (`up.render`, `up.link.follow`, etc.) or rely on HTML attributes.
+* If dynamically injecting HTML pages, the agent should re-run `up.framework.init()` **only once globally**, not after every fragment load.
+
+### Recommended CDN Sources
+
+* `https://unpkg.com/unpoly@3.x/`
+* `https://cdn.jsdelivr.net/npm/unpoly@3.x/`
+
+### Offline Use
+
+For fully offline or embedded environments, the agent can download both `.js` and `.css` files and reference them locally:
+
+```html
+<link rel="stylesheet" href="/assets/unpoly.min.css">
+<script src="/assets/unpoly.min.js"></script>
+```
+---
+
+## Agent Validation Checklist
+
+1. Verify `up-*` attributes match existing fragments.  
+2. Check backend returns valid fragment markup.  
+3. Ensure forms use `up-submit` and `up-fail-target`.  
+4. Overlay layers must have dismissable controls.  
+5. Use caching wisely (`up-cache`, `up.link.preload`).  
+6. Handle network and render events gracefully.  
+7. Log events (`up.log`) for debugging.  
+8. Confirm scroll/focus restoration after renders.  
+9. Gracefully degrade if JavaScript disabled.  
+10. Document reasoning and configuration.

+# Unpoly Quick Reference for AI Agents
+
+## Installation
+
+Include Unpoly from CDN in your HTML `<head>`:
+
+```html
+<script src="https://unpoly.com/unpoly.min.js"></script>
+<link rel="stylesheet" href="https://unpoly.com/unpoly.min.css">
+```
+
+## Core Concept
+
+Unpoly updates page fragments without full page reloads. Users click links/submit forms → server responds with HTML → Unpoly extracts and swaps matching fragments.
+
+---
+
+## 1. Following Links (Fragment Updates)
+
+### Basic Link Following
+
+```html
+<a href="/users/5" up-follow>View User</a>
+```
+
+Updates the `<main>` element (or `<body>` if no main exists) with content from `/users/5`.
+
+### Target Specific Fragment
+
+```html
+<a href="/users/5" up-target=".user-details">View User</a>
+
+<div class="user-details">
+  <!-- Content replaced here -->
+</div>
+```
+
+### Multiple Fragments
+
+```html
+<a href="/users/5" up-target=".profile, .activity">View User</a>
+```
+
+Updates both `.profile` and `.activity` from single response.
+
+### Append/Prepend Content
+
+```html
+<!-- Append to list -->
+<a href="/items?page=2" up-target=".items:after">Load More</a>
+
+<!-- Prepend to list -->
+<a href="/latest" up-target=".items:before">Show Latest</a>
+```
+
+### Handle All Links Automatically
+
+```js
+up.link.config.followSelectors.push('a[href]')
+```
+
+Now all links update fragments by default.
+
+---
+
+## 2. Submitting Forms
+
+### Basic Form Submission
+
+```html
+<form action="/users" method="post" up-submit>
+  <input name="email">
+  <button type="submit">Create</button>
+</form>
+```
+
+Submits via AJAX and updates `<main>` with response.
+
+### Target Specific Fragment
+
+```html
+<form action="/search" up-submit up-target=".results">
+  <input name="query">
+  <button>Search</button>
+</form>
+
+<div class="results">
+  <!-- Search results appear here -->
+</div>
+```
+
+### Handle Success vs. Error Responses
+
+```html
+<form action="/users" method="post" up-submit 
+      up-target="#success"
+      up-fail-target="form">
+  <input name="email">
+  <button>Create</button>
+</form>
+
+<div id="success">Success message here</div>
+```
+
+- **Success (2xx status)**: Updates `#success`
+- **Error (4xx/5xx status)**: Re-renders `form` with validation errors
+
+**Server must return HTTP 422** (or similar error code) for validation failures.
+
+---
+
+## 3. Opening Overlays (Modal, Drawer, Popup)
+
+### Modal Dialog
+
+```html
+<a href="/details" up-layer="new">Open Modal</a>
+```
+
+Opens `/details` in a modal overlay.
+
+### Drawer (Sidebar)
+
+```html
+<a href="/menu" up-layer="new drawer">Open Drawer</a>
+```
+
+### Popup (Anchored to Link)
+
+```html
+<a href="/help" up-layer="new popup">Help</a>
+```
+
+### Close Overlay When Condition Met
+
+```html
+<a href="/users/new" 
+   up-layer="new"
+   up-accept-location="/users/$id"
+   up-on-accepted="console.log('Created user:', value.id)">
+  New User
+</a>
+```
+
+Overlay auto-closes when URL matches `/users/123`, passes `{ id: 123 }` to callback.
+
+### Local Content (No Server Request)
+
+```html
+<a up-layer="new popup" up-content="<p>Help text here</p>">Help</a>
+```
+
+---
+
+## 4. Validation
+
+### Validate on Field Change
+
+```html
+<form action="/users" method="post">
+  <input name="email" up-validate>
+  <input name="password" up-validate>
+  <button type="submit">Register</button>
+</form>
+```
+
+When field loses focus → submits form with `X-Up-Validate: email` header → server re-renders form → Unpoly updates the field's parent `<fieldset>` (or closest form group).
+
+**Server must return HTTP 422** for validation errors.
+
+### Validate While Typing
+
+```html
+<input name="email" up-validate 
+       up-watch-event="input" 
+       up-watch-delay="300">
+```
+
+Validates 300ms after user stops typing.
+
+---
+
+## 5. Lazy Loading & Polling
+
+### Load When Element Appears in DOM
+
+```html
+<div id="menu" up-defer up-href="/menu">
+  Loading menu...
+</div>
+```
+
+Immediately loads `/menu` when placeholder renders.
+
+### Load When Scrolled Into View
+
+```html
+<div id="comments" up-defer="reveal" up-href="/comments">
+  Loading comments...
+</div>
+```
+
+Loads when element scrolls into viewport.
+
+### Auto-Refresh (Polling)
+
+```html
+<div class="status" up-poll up-interval="5000">
+  Current status
+</div>
+```
+
+Reloads fragment every 5 seconds from original URL.
+
+---
+
+## 6. Caching & Revalidation
+
+### Enable Caching
+
+```html
+<a href="/users" up-cache="true">Users</a>
+```
+
+Caches response, instantly shows cached content, then revalidates with server.
+
+### Disable Caching
+
+```html
+<a href="/stock" up-cache="false">Live Prices</a>
+```
+
+### Conditional Requests (Server-Side)
+
+Server sends:
+
+```http
+HTTP/1.1 200 OK
+ETag: "abc123"
+
+<div class="data">Content</div>
+```
+
+Next reload, Unpoly sends:
+
+```http
+GET /path
+If-None-Match: "abc123"
+```
+
+Server responds `304 Not Modified` if unchanged → saves bandwidth.
+

+
+## 7. Navigation Bar (Current Link Highlighting)
+
+```html
+<nav>
+  <a href="/home">Home</a>
+  <a href="/about">About</a>
+</nav>
+```
+
+Current page link gets `.up-current` class automatically.
+
+**Style it:**
+
+```css
+.up-current {
+  font-weight: bold;
+  color: blue;
+}
+```
+
+---
+
+## 8. Loading State
+
+### Feedback Classes
+
+Automatically applied:
+
+- `.up-active` on clicked link/button
+- `.up-loading` on targeted fragment
+
+**Style them:**
+
+```css
+.up-active { opacity: 0.6; }
+.up-loading { opacity: 0.8; }
+```
+
+### Disable Form While Submitting
+
+```html
+<form up-submit up-disable>
+  <input name="email">
+  <button>Submit</button>
+</form>
+```
+
+All fields disabled during submission.
+
+### Show Placeholder While Loading
+
+```html
+<a href="/data" up-target=".data" 
+   up-placeholder="<p>Loading...</p>">
+  Load Data
+</a>
+```
+
+---
+
+## 9. Preloading
+
+### Preload on Hover
+
+```html
+<a href="/users/5" up-preload>User Profile</a>
+```
+
+Starts loading when user hovers (90ms delay by default).
+
+### Preload Immediately
+
+```html
+<a href="/menu" up-preload="insert">Menu</a>
+```
+
+Loads as soon as link appears in DOM.
+
+---
+
+## 10. Templates (Client-Side HTML)
+
+### Define Template
+
+```html
+<template id="user-card">
+  <div class="card">
+    <h3>{{name}}</h3>
+    <p>{{email}}</p>
+  </div>
+</template>
+```
+
+### Use Template
+
+```html
+<a up-fragment="#user-card" 
+   up-use-data="{ name: 'Alice', email: 'alice@example.com' }">
+  Show User
+</a>
+```
+
+**Process variables with compiler:**
+
+```js
+up.compiler('.card', function(element, data) {
+  element.innerHTML = element.innerHTML
+    .replace(/{{name}}/g, data.name)
+    .replace(/{{email}}/g, data.email)
+})
+```
+
+---
+
+## 11. JavaScript API
+
+### Render Fragment
+
+```js
+up.render({ 
+  url: '/users/5', 
+  target: '.user-details' 
+})
+```
+
+### Navigate (Updates History)
+
+```js
+up.navigate({ 
+  url: '/users', 
+  target: 'main' 
+})
+```
+
+### Submit Form
+
+```js
+let form = document.querySelector('form')
+up.submit(form)
+```
+
+### Open Overlay
+
+```js
+up.layer.open({ 
+  url: '/users/new',
+  onAccepted: (event) => {
+    console.log('User created:', event.value)
+  }
+})
+```
+
+### Close Overlay with Value
+
+```js
+up.layer.accept({ id: 123, name: 'Alice' })
+```
+
+### Reload Fragment
+
+```js
+up.reload('.status')
+```
+
+---
+
+## 12. Request Headers (Server Protocol)
+
+Unpoly sends these headers with requests:
+
+| Header          | Value    | Purpose                         |
+| --------------- | -------- | ------------------------------- |
+| `X-Up-Version`  | `1.0.0`  | Identifies Unpoly request       |
+| `X-Up-Target`   | `.users` | Fragment selector being updated |
+| `X-Up-Mode`     | `modal`  | Current layer mode              |
+| `X-Up-Validate` | `email`  | Field being validated           |
+
+**Server can respond with:**
+
+| Header                   | Effect                   |
+| ------------------------ | ------------------------ |
+| `X-Up-Target: .other`    | Changes target selector  |
+| `X-Up-Accept-Layer: {}`  | Closes overlay (success) |
+| `X-Up-Dismiss-Layer: {}` | Closes overlay (cancel)  |
+
+---
+
+## 13. Common Patterns
+
+### Infinite Scrolling
+
+```html
+<div id="items">
+  <div>Item 1</div>
+  <div>Item 2</div>
+</div>
+
+<a id="next" href="/items?page=2" 
+   up-defer="reveal" 
+   up-target="#items:after, #next">
+  Load More
+</a>
+```
+
+### Dependent Form Fields
+
+```html
+<form action="/order">
+  <!-- Changing country updates city select -->
+  <select name="country" up-validate="#city">
+    <option>USA</option>
+    <option>Canada</option>
+  </select>
+  
+  <select name="city" id="city">
+    <option>New York</option>
+  </select>
+</form>
+```
+
+### Confirm Before Action
+
+```html
+<a href="/delete" up-method="delete" 
+   up-confirm="Really delete?">
+  Delete
+</a>
+```
+
+### Auto-Submit on Change
+
+```html
+<form action="/search" up-autosubmit>
+  <input name="query">
+</form>
+```
+
+Submits form when any field changes.
+
+---
+
+## 14. Error Handling
+
+### Handle Network Errors
+
+```js
+up.on('up:fragment:offline', function(event) {
+  if (confirm('You are offline. Retry?')) {
+    event.retry()
+  }
+})
+```
+
+### Handle Failed Responses
+
+```js
+try {
+  await up.render({ url: '/path', target: '.data' })
+} catch (error) {
+  if (error instanceof up.RenderResult) {
+    console.log('Server error:', error)
+  }
+}
+```
+
+---
+
+## 15. Compilers (Enhance Elements)
+
+### Basic Compiler
+
+```js
+up.compiler('.current-time', function(element) {
+  element.textContent = new Date().toString()
+})
+```
+
+Runs when `.current-time` is inserted (initial load OR fragment update).
+
+### Compiler with Cleanup
+
+```js
+up.compiler('.auto-refresh', function(element) {
+  let timer = setInterval(() => {
+    element.textContent = new Date().toString()
+  }, 1000)
+  
+  // Return destructor function
+  return () => clearInterval(timer)
+})
+```
+
+Destructor called when element is removed from DOM.
+
+---
+
+## Quick Reference Table
+
+| Task            | HTML                         | JavaScript                 |
+| --------------- | ---------------------------- | -------------------------- |
+| Follow link     | `<a href="/path" up-follow>` | `up.follow(link)`          |
+| Submit form     | `<form up-submit>`           | `up.submit(form)`          |
+| Target fragment | `up-target=".foo"`           | `{ target: '.foo' }`       |
+| Open modal      | `up-layer="new"`             | `up.layer.open({ url })`   |
+| Validate field  | `up-validate`                | `up.validate(field)`       |
+| Lazy load       | `up-defer`                   | —                          |
+| Poll fragment   | `up-poll`                    | —                          |
+| Preload link    | `up-preload`                 | `up.link.preload(link)`    |
+| Local content   | `up-content="<p>Hi</p>"`     | `{ content: '<p>Hi</p>' }` |
+| Append content  | `up-target=".list:after"`    | —                          |
+| Confirm action  | `up-confirm="Sure?"`         | `{ confirm: 'Sure?' }`     |
+
+---
+
+## Key Defaults
+
+- **Target**: Updates `<main>` (or `<body>`) if no `up-target` specified
+- **Caching**: Auto-enabled for GET requests during navigation
+- **History**: Auto-updated when rendering `<main>` or major fragments
+- **Scrolling**: Auto-scrolls to top when updating `<main>`
+- **Focus**: Auto-focuses new fragment
+- **Validation**: Targets field's parent `<fieldset>` or form group
+
+---
+
+## Best Practices for AI Agents
+
+1. **Always provide HTTP error codes**: Return 422 for validation errors, 404 for not found, etc.
+2. **Send full HTML responses**: Include entire page structure; Unpoly extracts needed fragments
+3. **Use semantic HTML**: `<main>`, `<nav>`, `<form>` elements work best
+4. **Set IDs on fragments**: Makes targeting easier (e.g., `<div id="user-123">`)
+5. **Return consistent selectors**: If request targets `.users`, response must contain `.users`
+
+---
+
+## Common Mistakes to Avoid
+
+❌ **Don't**: Return only partial HTML without wrapper
+```html
+<h1>Title</h1>
+<p>Content</p>
+```
+
+✅ **Do**: Wrap in target selector
+```html
+<div class="content">
+  <h1>Title</h1>
+  <p>Content</p>
+</div>
+```
+
+❌ **Don't**: Return 200 OK for validation errors  
+✅ **Do**: Return 422 Unprocessable Entity
+
+❌ **Don't**: Use `onclick="up.follow(this)"`  
+✅ **Do**: Use `up-follow` attribute (handles keyboard, accessibility)
+
+---
+
+## Server Response Examples
+
+### Successful Form Submission
+
+```http
+HTTP/1.1 200 OK
+
+<div id="success">
+  User created successfully!
+</div>
+```
+
+### Validation Error
+
+```http
+HTTP/1.1 422 Unprocessable Entity
+
+<form action="/users" method="post" up-submit>
+  <input name="email" value="invalid">
+  <div class="error">Email is invalid</div>
+  <button>Submit</button>
+</form>
+```
+
+### Partial Response (Optimized)
+
+```http
+HTTP/1.1 200 OK
+Vary: X-Up-Target
+
+<div class="user-details">
+  <!-- Only the targeted fragment -->
+</div>

+
+Returns the Blake3 256-bit hash of the provided data.
+
+```v
+fn sum_derive_key256(context []u8, key_material []u8) []u8
+```
+
+Computes the Blake3 256-bit derived-key hash based on the context and key material.
+
+```v
+fn sum_keyed256(data []u8, key []u8) []u8
+```
+
+Returns the Blake3 256-bit keyed hash of the data using the specified key.
+
+---
+
+### Digest-Based API
+
+```v
+fn Digest.new_derive_key_hash(context []u8) !Digest
+```
+
+Initializes a `Digest` struct for creating a Blake3 derived‑key hash, using the provided context.
+
+```v
+fn Digest.new_hash() !Digest
+```
+
+Initializes a `Digest` struct for a standard (unkeyed) Blake3 hash.
+

+```
+
+Initializes a `Digest` struct for a keyed Blake3 hash, with the given key.
+

+
+### `Digest` Methods
+
+```v
+fn (mut d Digest) write(data []u8) !
+```
+
+Feeds additional data bytes into the ongoing hash computation.
+
+```v
+fn (mut d Digest) checksum(size u64) []u8
+```
+
+Finalizes the hash and returns the resulting output.

+The `compress` module in V provides low-level functionalities for compressing and decompressing byte arrays.
+
+**Functions Overview (Low-Level):**
+
+*   **`compress(data []u8, flags int) ![]u8`**: Compresses an array of bytes.
+*   **`decompress(data []u8, flags int) ![]u8`**: Decompresses an array of bytes.
+*   **`decompress_with_callback(data []u8, cb ChunkCallback, userdata voidptr, flags int) !u64`**: Decompresses byte arrays using a callback function for chunks.
+
+**Type Definition (Low-Level):**
+
+*   **`ChunkCallback`**: A function type `fn (chunk []u8, userdata voidptr) int` used to receive decompressed chunks.
+
+---
+
+**`compress.gzip` Module (High-Level Gzip Operations):**
+
+For high-level gzip compression and decompression, use the `compress.gzip` module. This module provides a more convenient and recommended way to handle gzip operations compared to the low-level `compress` module.
+
+**Key Features of `compress.gzip`:**
+
+*   **`compress(data []u8, params CompressParams) ![]u8`**: Compresses data using gzip, allowing specification of `CompressParams` like `compression_level` (0-4095).
+*   **`decompress(data []u8, params DecompressParams) ![]u8`**: Decompresses gzip-compressed data, allowing specification of `DecompressParams` for verification.
+*   **`decompress_with_callback(data []u8, cb compr.ChunkCallback, userdata voidptr, params DecompressParams) !int`**: Decompresses gzip data with a callback for chunks, similar to the low-level version but for gzip streams.
+*   **`validate(data []u8, params DecompressParams) !GzipHeader`**: Validates a gzip header and returns its details.
+
+**Parameter Structures:**
+
+*   **`CompressParams`**: Configures compression, primarily `compression_level` (0-4095).
+*   **`DecompressParams`**: Configures decompression, including `verify_header_checksum`, `verify_length`, and `verify_checksum`.
+*   **`GzipHeader`**: Represents the structure of a gzip header.
+
+**Inline Code Example (Gzip Compression/Decompression):**
+
+```v
+import compress.gzip
+
+data := 'Hello, Gzip!'
+compressed := gzip.compress(data.bytes(), compression_level: 4095)!
+decompressed := gzip.decompress(compressed)!
+
+// Check if decompressed data matches original
+// if data.bytes() == decompressed { ... }
+```
+
+**Important Note:** Always prefer `compress.gzip` for general gzip compression/decompression tasks over the low-level `compress` module.

+
+append the second array `b` to the first array `a`, and return the result. Note, that unlike arrays.concat, arrays.append is less flexible, but more efficient, since it does not require you to use ...a for the second parameter.
+
+Example
+```v
+
+arrays.append([1, 3, 5, 7], [2, 4, 6, 8]) // => [1, 3, 5, 7, 2, 4, 6, 8]

+```
+
+binary_search, requires `array` to be sorted, returns index of found item or error. Binary searches on sorted lists can be faster than other array searches because at maximum the algorithm only has to traverse log N elements
+
+Example
+```v
