fix(k8s): add hostPath support for compose host path mounts

Add support for Docker Compose host path mounts (like ../config/file:/path)
in k8s deployments. Previously these were silently skipped, causing k8s
deployments to fail when compose files used host path mounts.

Changes:
- Add helper functions for host path detection and name sanitization
- Generate kind extraMounts for host path mounts
- Create hostPath volumes in pod specs for host path mounts
- Create volumeMounts with sanitized names for host path mounts

+# Plan: Make Stack-Orchestrator AI-Friendly
+
+## Goal
+
+Make the stack-orchestrator repository easier for AI tools (Claude Code, Cursor, Copilot) to understand and use for generating stacks, including adding a `create-stack` command.
+
+---
+
+## Part 1: Documentation & Context Files
+
+### 1.1 Add CLAUDE.md
+
+Create a root-level context file for AI assistants.
+
+**File:** `CLAUDE.md`
+
+Contents:
+- Project overview (what stack-orchestrator does)
+- Stack creation workflow (step-by-step)
+- File naming conventions
+- Required vs optional fields in stack.yml
+- Common patterns and anti-patterns
+- Links to example stacks (simple, medium, complex)
+
+### 1.2 Add JSON Schema for stack.yml
+
+Create formal validation schema.
+
+**File:** `schemas/stack-schema.json`
+
+Benefits:
+- AI tools can validate generated stacks
+- IDEs provide autocomplete
+- CI can catch errors early
+
+### 1.3 Add Template Stack with Comments
+
+Create an annotated template for reference.
+
+**File:** `stack_orchestrator/data/stacks/_template/stack.yml`
+
+```yaml
+# Stack definition template - copy this directory to create a new stack
+version: "1.2"  # Required: 1.0, 1.1, or 1.2
+name: my-stack  # Required: lowercase, hyphens only
+description: "Human-readable description"  # Optional
+repos:          # Git repositories to clone
+  - github.com/org/repo
+containers:     # Container images to build (must have matching container-build/)
+  - cerc/my-container
+pods:           # Deployment units (must have matching docker-compose-{pod}.yml)
+  - my-pod
+```
+
+### 1.4 Document Validation Rules
+
+Create explicit documentation of constraints currently scattered in code.
+
+**File:** `docs/stack-format.md`
+
+Contents:
+- Container names must start with `cerc/`
+- Pod names must match compose file: `docker-compose-{pod}.yml`
+- Repository format: `host/org/repo[@ref]`
+- Stack directory name should match `name` field
+- Version field options and differences
+
+---
+
+## Part 2: Add `create-stack` Command
+
+### 2.1 Command Overview
+
+```bash
+laconic-so create-stack --repo github.com/org/my-app [--name my-app] [--type webapp]
+```
+
+**Behavior:**
+1. Parse repo URL to extract app name (if --name not provided)
+2. Create `stacks/{name}/stack.yml`
+3. Create `container-build/cerc-{name}/Dockerfile` and `build.sh`
+4. Create `compose/docker-compose-{name}.yml`
+5. Update list files (repository-list.txt, container-image-list.txt, pod-list.txt)
+
+### 2.2 Files to Create
+
+| File | Purpose |
+|------|---------|
+| `stack_orchestrator/create/__init__.py` | Package init |
+| `stack_orchestrator/create/create_stack.py` | Command implementation |
+
+### 2.3 Files to Modify
+
+| File | Change |
+|------|--------|
+| `stack_orchestrator/main.py` | Add import and `cli.add_command()` |
+
+### 2.4 Command Options
+
+| Option | Required | Description |
+|--------|----------|-------------|
+| `--repo` | Yes | Git repository URL (e.g., github.com/org/repo) |
+| `--name` | No | Stack name (defaults to repo name) |
+| `--type` | No | Template type: webapp, service, empty (default: webapp) |
+| `--force` | No | Overwrite existing files |
+
+### 2.5 Template Types
+
+| Type | Base Image | Port | Use Case |
+|------|------------|------|----------|
+| webapp | node:20-bullseye-slim | 3000 | React/Vue/Next.js apps |
+| service | python:3.11-slim | 8080 | Python backend services |
+| empty | none | none | Custom from scratch |
+
+---
+
+## Part 3: Implementation Summary
+
+### New Files (6)
+
+1. `CLAUDE.md` - AI assistant context
+2. `schemas/stack-schema.json` - Validation schema
+3. `stack_orchestrator/data/stacks/_template/stack.yml` - Annotated template
+4. `docs/stack-format.md` - Stack format documentation
+5. `stack_orchestrator/create/__init__.py` - Package init
+6. `stack_orchestrator/create/create_stack.py` - Command implementation
+
+### Modified Files (1)
+
+1. `stack_orchestrator/main.py` - Register create-stack command
+
+---
+
+## Verification
+
+```bash
+# 1. Command appears in help
+laconic-so --help | grep create-stack
+
+# 2. Dry run works
+laconic-so --dry-run create-stack --repo github.com/org/test-app
+
+# 3. Creates all expected files
+laconic-so create-stack --repo github.com/org/test-app
+ls stack_orchestrator/data/stacks/test-app/
+ls stack_orchestrator/data/container-build/cerc-test-app/
+ls stack_orchestrator/data/compose/docker-compose-test-app.yml
+
+# 4. Build works with generated stack
+laconic-so --stack test-app build-containers

+# Implementing `laconic-so create-stack` Command
+
+A plan for adding a new CLI command to scaffold stack files automatically.
+
+---
+
+## Overview
+
+Add a `create-stack` command that generates all required files for a new stack:
+
+```bash
+laconic-so create-stack --name my-stack --type webapp
+```
+
+**Output:**
+```
+stack_orchestrator/data/
+├── stacks/my-stack/stack.yml
+├── container-build/cerc-my-stack/
+│   ├── Dockerfile
+│   └── build.sh
+└── compose/docker-compose-my-stack.yml
+
+Updated: repository-list.txt, container-image-list.txt, pod-list.txt
+```
+
+---
+
+## CLI Architecture Summary
+
+### Command Registration Pattern
+
+Commands are Click functions registered in `main.py`:
+
+```python
+# main.py (line ~70)
+from stack_orchestrator.create import create_stack
+cli.add_command(create_stack.command, "create-stack")
+```
+
+### Global Options Access
+
+```python
+from stack_orchestrator.opts import opts
+
+if not opts.o.quiet:
+    print("message")
+if opts.o.dry_run:
+    print("(would create files)")
+```
+
+### Key Utilities
+
+| Function | Location | Purpose |
+|----------|----------|---------|
+| `get_yaml()` | `util.py` | YAML parser (ruamel.yaml) |
+| `get_stack_path(stack)` | `util.py` | Resolve stack directory path |
+| `error_exit(msg)` | `util.py` | Print error and exit(1) |
+

+
+Add command registration (after line ~78):
+```python
+cli.add_command(create_stack.command, "create-stack")

+
+---
+
+## Implementation Steps
+
+### Step 1: Create module structure
+```bash
+mkdir -p stack_orchestrator/create
+touch stack_orchestrator/create/__init__.py
+```
+
+### Step 2: Create the command file
+Create `stack_orchestrator/create/create_stack.py` with the code above.
+
+### Step 3: Register in main.py
+Add the import and `cli.add_command()` line.
+
+### Step 4: Test the command
+```bash
+# Show help
+laconic-so create-stack --help
+
+# Dry run
+laconic-so --dry-run create-stack --name test-app --type webapp
+
+# Create a stack
+laconic-so create-stack --name test-app --type webapp --repo github.com/org/test-app

+## Template Types
+
+| Type | Base Image | Port | Use Case |
+|------|------------|------|----------|
+| `webapp` | node:20-bullseye-slim | 3000 | React/Vue/Next.js apps |
+| `service` | python:3.11-slim | 8080 | Python backend services |
+| `empty` | none | none | Custom from scratch |
+
+---
+
+## Future Enhancements
+
+1. **Interactive mode** - Prompt for values if not provided
+2. **More templates** - Go, Rust, database stacks
+3. **Template from existing** - `--from-stack existing-stack`
+4. **External stack support** - Create in custom directory
+5. **Validation command** - `laconic-so validate-stack --name my-stack`
+
+---

+
+## deploy
+
+The `deploy` command group manages persistent deployments. The general workflow is `deploy init` to generate a spec file, then `deploy create` to create a deployment directory from the spec, then runtime commands like `deploy up` and `deploy down`.
+
+### deploy init
+
+Generate a deployment spec file from a stack definition:
+```
+$ laconic-so --stack <stack-name> deploy init --output <spec-file>
+```
+
+Options:
+- `--output` (required): write spec file here
+- `--config`: provide config variables for the deployment
+- `--config-file`: provide config variables in a file
+- `--kube-config`: provide a config file for a k8s deployment
+- `--image-registry`: provide a container image registry url for this k8s cluster
+- `--map-ports-to-host`: map ports to the host (`any-variable-random`, `localhost-same`, `any-same`, `localhost-fixed-random`, `any-fixed-random`)
+
+### deploy create
+
+Create a deployment directory from a spec file:
+```
+$ laconic-so --stack <stack-name> deploy create --spec-file <spec-file> --deployment-dir <dir>
+```
+
+Update an existing deployment in-place (preserving data volumes and env file):
+```
+$ laconic-so --stack <stack-name> deploy create --spec-file <spec-file> --deployment-dir <dir> --update
+```
+
+Options:
+- `--spec-file` (required): spec file to use
+- `--deployment-dir`: target directory for deployment files
+- `--update`: update an existing deployment directory, preserving data volumes and env file. Changed files are backed up with a `.bak` suffix. The deployment's `config.env` and `deployment.yml` are also preserved.
+- `--network-dir`: network configuration supplied in this directory
+- `--initial-peers`: initial set of persistent peers
+
+### deploy up
+
+Start a deployment:
+```
+$ laconic-so deployment --dir <deployment-dir> up
+```
+
+### deploy down
+
+Stop a deployment:
+```
+$ laconic-so deployment --dir <deployment-dir> down
+```
+Use `--delete-volumes` to also remove data volumes.
+
+### deploy ps
+
+Show running services:
+```
+$ laconic-so deployment --dir <deployment-dir> ps
+```
+
+### deploy logs
+
+View service logs:
+```
+$ laconic-so deployment --dir <deployment-dir> logs

+# Docker Compose Deployment Guide
+
+## Introduction
+
+### What is a Deployer?
+
+In stack-orchestrator, a **deployer** provides a uniform interface for orchestrating containerized applications. This guide focuses on Docker Compose deployments, which is the default and recommended deployment mode.
+
+While stack-orchestrator also supports Kubernetes (`k8s`) and Kind (`k8s-kind`) deployments, those are out of scope for this guide. See the [Kubernetes Enhancements](./k8s-deployment-enhancements.md) documentation for advanced deployment options.
+
+## Prerequisites
+
+To deploy stacks using Docker Compose, you need:
+
+- Docker Engine (20.10+)
+- Docker Compose plugin (v2.0+)
+- Python 3.8+
+- stack-orchestrator installed (`laconic-so`)
+
+**That's it!** No additional infrastructure is required. If you have Docker installed, you're ready to deploy.
+
+## Deployment Workflow
+
+The typical deployment workflow consists of four main steps:
+
+1. **Setup repositories and build containers** (first time only)
+2. **Initialize deployment specification**
+3. **Create deployment directory**
+4. **Start and manage services**
+
+## Quick Start Example
+
+Here's a complete example using the built-in `test` stack:
+
+```bash
+# Step 1: Setup (first time only)
+laconic-so --stack test setup-repositories
+laconic-so --stack test build-containers
+
+# Step 2: Initialize deployment spec
+laconic-so --stack test deploy init --output test-spec.yml
+
+# Step 3: Create deployment directory
+laconic-so --stack test deploy create \
+  --spec-file test-spec.yml \
+  --deployment-dir test-deployment
+
+# Step 4: Start services
+laconic-so deployment --dir test-deployment start
+
+# View running services
+laconic-so deployment --dir test-deployment ps
+
+# View logs
+laconic-so deployment --dir test-deployment logs
+
+# Stop services (preserves data)
+laconic-so deployment --dir test-deployment stop
+```
+
+## Deployment Workflows
+
+Stack-orchestrator supports two deployment workflows:
+
+### 1. Deployment Directory Workflow (Recommended)
+
+This workflow creates a persistent deployment directory that contains all configuration and data.
+
+**When to use:**
+- Production deployments
+- When you need to preserve configuration
+- When you want to manage multiple deployments
+- When you need persistent volume data
+
+**Example:**
+
+```bash
+# Initialize deployment spec
+laconic-so --stack fixturenet-eth deploy init --output eth-spec.yml
+
+# Optionally edit eth-spec.yml to customize configuration
+
+# Create deployment directory
+laconic-so --stack fixturenet-eth deploy create \
+  --spec-file eth-spec.yml \
+  --deployment-dir my-eth-deployment
+
+# Start the deployment
+laconic-so deployment --dir my-eth-deployment start
+
+# Manage the deployment
+laconic-so deployment --dir my-eth-deployment ps
+laconic-so deployment --dir my-eth-deployment logs
+laconic-so deployment --dir my-eth-deployment stop
+```
+
+### 2. Quick Deploy Workflow
+
+This workflow deploys directly without creating a persistent deployment directory.
+
+**When to use:**
+- Quick testing
+- Temporary deployments
+- Simple stacks that don't require customization
+
+**Example:**
+
+```bash
+# Start the stack directly
+laconic-so --stack test deploy up
+
+# Check service status
+laconic-so --stack test deploy port test 80
+
+# View logs
+laconic-so --stack test deploy logs
+
+# Stop (preserves volumes)
+laconic-so --stack test deploy down
+
+# Stop and remove volumes
+laconic-so --stack test deploy down --delete-volumes
+```
+
+## Real-World Example: Ethereum Fixturenet
+
+Deploy a local Ethereum testnet with Geth and Lighthouse:
+
+```bash
+# Setup (first time only)
+laconic-so --stack fixturenet-eth setup-repositories
+laconic-so --stack fixturenet-eth build-containers
+
+# Initialize with default configuration
+laconic-so --stack fixturenet-eth deploy init --output eth-spec.yml
+
+# Create deployment
+laconic-so --stack fixturenet-eth deploy create \
+  --spec-file eth-spec.yml \
+  --deployment-dir fixturenet-eth-deployment
+
+# Start the network
+laconic-so deployment --dir fixturenet-eth-deployment start
+
+# Check status
+laconic-so deployment --dir fixturenet-eth-deployment ps
+
+# Access logs from specific service
+laconic-so deployment --dir fixturenet-eth-deployment logs fixturenet-eth-geth-1
+
+# Stop the network (preserves blockchain data)
+laconic-so deployment --dir fixturenet-eth-deployment stop
+
+# Start again - blockchain data is preserved
+laconic-so deployment --dir fixturenet-eth-deployment start
+
+# Clean up everything including data
+laconic-so deployment --dir fixturenet-eth-deployment stop --delete-volumes
+```
+
+## Configuration
+
+### Passing Configuration Parameters
+
+Configuration can be passed in three ways:
+
+**1. At init time via `--config` flag:**
+
+```bash
+laconic-so --stack test deploy init --output spec.yml \
+  --config PARAM1=value1,PARAM2=value2
+```
+
+**2. Edit the spec file after init:**
+
+```bash
+# Initialize
+laconic-so --stack test deploy init --output spec.yml
+
+# Edit spec.yml
+vim spec.yml
+```
+
+Example spec.yml:
+```yaml
+stack: test
+config:
+  PARAM1: value1
+  PARAM2: value2
+```
+
+**3. Docker Compose defaults:**
+
+Environment variables defined in the stack's `docker-compose-*.yml` files are used as defaults. Configuration from the spec file overrides these defaults.
+
+### Port Mapping
+
+By default, services are accessible on randomly assigned host ports. To find the mapped port:
+
+```bash
+# Find the host port for container port 80 on service 'webapp'
+laconic-so deployment --dir my-deployment port webapp 80
+
+# Output example: 0.0.0.0:32768
+```
+
+To configure fixed ports, edit the spec file before creating the deployment:
+
+```yaml
+network:
+  ports:
+    webapp:
+      - '8080:80'  # Maps host port 8080 to container port 80
+    api:
+      - '3000:3000'
+```
+
+Then create the deployment:
+
+```bash
+laconic-so --stack my-stack deploy create \
+  --spec-file spec.yml \
+  --deployment-dir my-deployment
+```
+
+### Volume Persistence
+
+Volumes are preserved between stop/start cycles by default:
+
+```bash
+# Stop but keep data
+laconic-so deployment --dir my-deployment stop
+
+# Start again - data is still there
+laconic-so deployment --dir my-deployment start
+```
+
+To completely remove all data:
+
+```bash
+# Stop and delete all volumes
+laconic-so deployment --dir my-deployment stop --delete-volumes
+```
+
+Volume data is stored in `<deployment-dir>/data/`.
+
+## Common Operations
+
+### Viewing Logs
+
+```bash
+# All services, continuous follow
+laconic-so deployment --dir my-deployment logs --follow
+
+# Last 100 lines from all services
+laconic-so deployment --dir my-deployment logs --tail 100
+
+# Specific service only
+laconic-so deployment --dir my-deployment logs webapp
+
+# Combine options
+laconic-so deployment --dir my-deployment logs --tail 50 --follow webapp
+```
+
+### Executing Commands in Containers
+
+```bash
+# Execute a command in a running service
+laconic-so deployment --dir my-deployment exec webapp ls -la
+
+# Interactive shell
+laconic-so deployment --dir my-deployment exec webapp /bin/bash
+
+# Run command with specific environment variables
+laconic-so deployment --dir my-deployment exec webapp env VAR=value command
+```
+
+### Checking Service Status
+
+```bash
+# List all running services
+laconic-so deployment --dir my-deployment ps
+
+# Check using Docker directly
+docker ps
+```
+
+### Updating a Running Deployment
+
+If you need to change configuration after deployment:
+
+```bash
+# 1. Edit the spec file
+vim my-deployment/spec.yml
+
+# 2. Regenerate configuration
+laconic-so deployment --dir my-deployment update
+
+# 3. Restart services to apply changes
+laconic-so deployment --dir my-deployment stop
+laconic-so deployment --dir my-deployment start
+```
+
+## Multi-Service Deployments
+
+Many stacks deploy multiple services that work together:
+
+```bash
+# Deploy a stack with multiple services
+laconic-so --stack laconicd-with-console deploy init --output spec.yml
+laconic-so --stack laconicd-with-console deploy create \
+  --spec-file spec.yml \
+  --deployment-dir laconicd-deployment
+
+laconic-so deployment --dir laconicd-deployment start
+
+# View all services
+laconic-so deployment --dir laconicd-deployment ps
+
+# View logs from specific services
+laconic-so deployment --dir laconicd-deployment logs laconicd
+laconic-so deployment --dir laconicd-deployment logs console
+```
+
+## ConfigMaps
+
+ConfigMaps allow you to mount configuration files into containers:
+
+```bash
+# 1. Create the config directory in your deployment
+mkdir -p my-deployment/data/my-config
+echo "database_url=postgres://localhost" > my-deployment/data/my-config/app.conf
+
+# 2. Reference in spec file
+vim my-deployment/spec.yml
+```
+
+Add to spec.yml:
+```yaml
+configmaps:
+  my-config: ./data/my-config
+```
+
+```bash
+# 3. Restart to apply
+laconic-so deployment --dir my-deployment stop
+laconic-so deployment --dir my-deployment start
+```
+
+The files will be mounted in the container at `/config/` (or as specified by the stack).
+
+## Deployment Directory Structure
+
+A typical deployment directory contains:
+
+```
+my-deployment/
+├── compose/
+│   └── docker-compose-*.yml    # Generated compose files
+├── config.env                   # Environment variables
+├── deployment.yml              # Deployment metadata
+├── spec.yml                    # Deployment specification
+└── data/                       # Volume mounts and configs
+    ├── service-data/           # Persistent service data
+    └── config-maps/            # ConfigMap files
+```
+
+## Troubleshooting
+
+### Common Issues
+
+**Problem: "Cannot connect to Docker daemon"**
+
+```bash
+# Ensure Docker is running
+docker ps
+
+# Start Docker if needed (macOS)
+open -a Docker
+
+# Start Docker (Linux)
+sudo systemctl start docker
+```
+
+**Problem: "Port already in use"**
+
+```bash
+# Either stop the conflicting service or use different ports
+# Edit spec.yml before creating deployment:
+
+network:
+  ports:
+    webapp:
+      - '8081:80'  # Use 8081 instead of 8080
+```
+
+**Problem: "Image not found"**
+
+```bash
+# Build containers first
+laconic-so --stack your-stack build-containers
+```
+
+**Problem: Volumes not persisting**
+
+```bash
+# Check if you used --delete-volumes when stopping
+# Volume data is in: <deployment-dir>/data/
+
+# Don't use --delete-volumes if you want to keep data:
+laconic-so deployment --dir my-deployment stop
+
+# Only use --delete-volumes when you want to reset completely:
+laconic-so deployment --dir my-deployment stop --delete-volumes
+```
+
+**Problem: Services not starting**
+
+```bash
+# Check logs for errors
+laconic-so deployment --dir my-deployment logs
+
+# Check Docker container status
+docker ps -a
+
+# Try stopping and starting again
+laconic-so deployment --dir my-deployment stop
+laconic-so deployment --dir my-deployment start
+```
+
+### Inspecting Deployment State
+
+```bash
+# Check deployment directory structure
+ls -la my-deployment/
+
+# Check running containers
+docker ps
+
+# Check container details
+docker inspect <container-name>
+
+# Check networks
+docker network ls
+
+# Check volumes
+docker volume ls
+```
+
+## CLI Commands Reference
+
+### Stack Operations
+
+```bash
+# Clone required repositories
+laconic-so --stack <name> setup-repositories
+
+# Build container images
+laconic-so --stack <name> build-containers
+```
+
+### Deployment Initialization
+
+```bash
+# Initialize deployment spec with defaults
+laconic-so --stack <name> deploy init --output <spec-file>
+
+# Initialize with configuration
+laconic-so --stack <name> deploy init --output <spec-file> \
+  --config PARAM1=value1,PARAM2=value2
+```
+
+### Deployment Creation
+
+```bash
+# Create deployment directory from spec
+laconic-so --stack <name> deploy create \
+  --spec-file <spec-file> \
+  --deployment-dir <dir>
+```
+
+### Deployment Management
+
+```bash
+# Start all services
+laconic-so deployment --dir <dir> start
+
+# Stop services (preserves volumes)
+laconic-so deployment --dir <dir> stop
+
+# Stop and remove volumes
+laconic-so deployment --dir <dir> stop --delete-volumes
+
+# List running services
+laconic-so deployment --dir <dir> ps
+
+# View logs
+laconic-so deployment --dir <dir> logs [--tail N] [--follow] [service]
+
+# Show mapped port
+laconic-so deployment --dir <dir> port <service> <private-port>
+
+# Execute command in service
+laconic-so deployment --dir <dir> exec <service> <command>
+
+# Update configuration
+laconic-so deployment --dir <dir> update
+```
+
+### Quick Deploy Commands
+
+```bash
+# Start stack directly
+laconic-so --stack <name> deploy up

+# Deploying to the Laconic Network
+
+## Overview
+
+The Laconic network uses a **registry-based deployment model** where everything is published as blockchain records.
+
+## Key Documentation in stack-orchestrator
+
+- `docs/laconicd-with-console.md` - Setting up a laconicd network
+- `docs/webapp.md` - Webapp building/running
+- `stack_orchestrator/deploy/webapp/` - Implementation (14 modules)
+
+## Core Concepts
+
+### LRN (Laconic Resource Name)
+Format: `lrn://laconic/[namespace]/[name]`
+
+Examples:
+- `lrn://laconic/deployers/my-deployer-name`
+- `lrn://laconic/dns/example.com`
+- `lrn://laconic/deployments/example.com`
+
+### Registry Record Types
+
+| Record Type | Purpose |
+|-------------|---------|
+| `ApplicationRecord` | Published app metadata |
+| `WebappDeployer` | Deployment service offering |
+| `ApplicationDeploymentRequest` | User's request to deploy |
+| `ApplicationDeploymentAuction` | Optional bidding for deployers |
+| `ApplicationDeploymentRecord` | Completed deployment result |
+
+## Deployment Workflows
+
+### 1. Direct Deployment
+
+```
+User publishes ApplicationDeploymentRequest
+    → targets specific WebappDeployer (by LRN)
+    → includes payment TX hash
+    → Deployer picks up request, builds, deploys, publishes result
+```
+
+### 2. Auction-Based Deployment
+
+```
+User publishes ApplicationDeploymentAuction
+    → Deployers bid (commit/reveal phases)
+    → Winner selected
+    → User publishes request targeting winner
+```
+
+## Key CLI Commands
+
+### Publish a Deployer Service
+```bash
+laconic-so publish-webapp-deployer --laconic-config config.yml \
+  --api-url https://deployer-api.example.com \
+  --name my-deployer \
+  --payment-address laconic1... \
+  --minimum-payment 1000alnt
+```
+
+### Request Deployment (User Side)
+```bash
+laconic-so request-webapp-deployment --laconic-config config.yml \
+  --app lrn://laconic/apps/my-app \
+  --deployer lrn://laconic/deployers/xyz \
+  --make-payment auto
+```
+
+### Run Deployer Service (Deployer Side)
+```bash
+laconic-so deploy-webapp-from-registry --laconic-config config.yml --discover
+```
+
+## Laconic Config File
+
+All tools require a laconic config file (`laconic.toml`):
+
+```toml
+[cosmos]
+address_prefix = "laconic"
+chain_id = "laconic_9000-1"
+endpoint = "http://localhost:26657"
+key = "<account-name>"
+password = "<account-password>"
+```
+
+## Setting Up a Local Laconicd Network
+
+```bash
+# Clone and build
+laconic-so --stack fixturenet-laconic-loaded setup-repositories
+laconic-so --stack fixturenet-laconic-loaded build-containers
+laconic-so --stack fixturenet-laconic-loaded deploy create
+laconic-so deployment --dir laconic-loaded-deployment start
+
+# Check status
+laconic-so deployment --dir laconic-loaded-deployment exec cli "laconic registry status"
+```
+
+## Key Implementation Files
+
+| File | Purpose |
+|------|---------|
+| `publish_webapp_deployer.py` | Register deployment service on network |
+| `publish_deployment_auction.py` | Create auction for deployers to bid on |
+| `handle_deployment_auction.py` | Monitor and bid on auctions (deployer-side) |
+| `request_webapp_deployment.py` | Create deployment request (user-side) |
+| `deploy_webapp_from_registry.py` | Process requests and deploy (deployer-side) |
+| `request_webapp_undeployment.py` | Request app removal |
+| `undeploy_webapp_from_registry.py` | Process removal requests |
+| `util.py` | LaconicRegistryClient - all registry interactions |
+
+## Payment System
+
+- **Token Denom**: `alnt` (Laconic network tokens)
+- **Payment Options**:
+  - `--make-payment`: Create new payment with amount (or "auto" for deployer's minimum)
+  - `--use-payment`: Reference existing payment TX
+
+## What's NOT Well-Documented
+
+1. No end-to-end tutorial for full deployment workflow
+2. Stack publishing (vs webapp) process unclear
+3. LRN naming conventions not formally specified
+4. Payment economics and token mechanics
