Perfect! I've successfully created a comprehensive Polkadot Zombienet taskserv for the provisioning system. Here's what was built:

  🧟 Polkadot Zombienet Taskserv (polkadot-zombienet)

  Created files:
  - taskservs/polkadot-zombienet/kcl/polkadot-zombienet.k - Complete KCL schema definitions
  - taskservs/polkadot-zombienet/default/provisioning.toml - Service metadata
  - taskservs/polkadot-zombienet/default/env-polkadot-zombienet.j2 - Environment configuration
  - taskservs/polkadot-zombienet/default/install-polkadot-zombienet.sh - Installation script
  - taskservs/polkadot-zombienet/default/prepare - Preparation and validation script
  - taskservs/polkadot-zombienet/default/network-config.toml.j2 - Dynamic network configuration template

  Network Templates:
  - simple-network.toml - Minimal 2-node relay chain (Alice + Bob)
  - parachain-network.toml - Relay chain with one parachain (3 validators + 1 collator)
  - multi-parachain-network.toml - Multi-parachain setup with XCM testing (4 validators + 3 parachains)

  Test Scripts:
  - test-basic.zndsl - Basic network functionality tests
  - test-parachain.zndsl - Parachain-specific functionality tests

  Service Management:
  - zombienet-service.sh.j2 - Service management script template

  🔧 Key Features

  Multi-Provider Support

  - Native Provider: Downloads and runs Polkadot/Parachain binaries locally
  - Kubernetes Provider: Deploys networks to Kubernetes clusters with monitoring
  - Podman Provider: Uses Podman containers with rootless support

  Network Configuration

  - Relay Chain: Configurable validators (Alice, Bob, Charlie, Dave)
  - Parachains: Multiple parachain support with custom collators
  - Chain Types: Rococo-local, Westend-local, Kusama-local, Polkadot-local
  - Custom Images: Support for custom Docker images and binaries

  Management Tools

  - zombienet-manager: CLI tool for network management
    - spawn - Start networks
    - test - Run test suites
    - list - Show available networks
    - logs - View network logs
    - clean - Cleanup processes

  Testing Framework

  - ZNDSL Tests: Domain-specific language for network testing
  - Block Production: Verify relay chain and parachain block production
  - Connectivity: Test node peer connections
  - Registration: Verify parachain registration

  📋 Usage Examples

  Deploy Simple Network

  ./core/nulib/provisioning taskserv create polkadot-zombienet

  # Start simple 2-node network
  zombienet-manager spawn

  # Start with custom network
  zombienet-manager spawn /var/lib/zombienet/networks/parachain-network.toml

  Test Networks

  # Run basic tests
  zombienet-manager test /var/lib/zombienet/test-basic.zndsl

  # Run parachain tests
  zombienet-manager test /var/lib/zombienet/test-parachain.zndsl

  Network Management

  # List available networks
  zombienet-manager list

  # View logs
  zombienet-manager logs

  # Cleanup
  zombienet-manager clean

  🎯 Configuration Options

  Provider Settings

  - provider: native, kubernetes, podman
  - timeout: Network spawn timeout (default: 1000s)
  - enable_tracing: Enable detailed tracing
  - backchannel: Enable node communication backchannel

  Relay Chain

  - chain: rococo-local, westend-local, kusama-local, polkadot-local
  - default_image: Docker image for relay chain nodes
  - nodes: Array of validator nodes with custom configurations

  Parachains

  - id: Parachain ID (1-4000)
  - collators: Array of collator nodes
  - genesis_wasm: Custom parachain WASM runtime
  - balance: Initial parachain balance

  Provider-Specific

  - Kubernetes: namespace, monitoring, prometheus prefix
  - Podman: monitoring port, rootless support
  - Native: automatic binary downloads

  🚀 Advanced Features

  Binary Management

  - Automatic download of Polkadot and Parachain binaries
  - Version-specific binary support
  - Custom binary path configuration
  - Symlink management for PATH access

  Monitoring & Logging

  - Centralized log management
  - Provider-specific monitoring (Prometheus, Grafana)
  - Network process tracking
  - Real-time log tailing

  Development Support

  - Pre-configured test networks
  - XCM testing setup
  - Multi-parachain environments
  - Custom collator configurations

  The service can be deployed using: ./core/nulib/provisioning taskserv create polkadot-zombienet

  This provides a complete ephemeral network testing platform for Polkadot/Substrate development, supporting everything from simple
  relay chains to complex multi-parachain networks with XCM testing capabilities. Perfect for developers working on parachain
  development, cross-chain messaging, and network validation testing.
