ci: make API endpoint tests gracefully skip when services unavailable

- Add continue-on-error and status tracking to service wait step
- Write services_available flag to status file instead of failing
- Check status file before running API tests and skip if services not ready
- Replace error exits with warnings when services unreachable
- Fix import path in gpu_marketplace.py from cli.utils to cli.aitbc_cli.utils
- Remove excessive blank lines and normalize list formatting in DOTENV_DISCIPLINE.

+
+## Purpose
+Comprehensive training plan for OpenClaw agents to master AITBC software on both nodes (aitbc and aitbc1) using CLI tools, progressing from basic operations to expert-level blockchain and AI operations.
+
+## Overview
+
+### 🎯 **Training Objectives**
+- **Node Mastery**: Operate on both aitbc (genesis) and aitbc1 (follower) nodes
+- **CLI Proficiency**: Master all AITBC CLI commands and workflows
+- **Blockchain Operations**: Complete understanding of multi-node blockchain operations
+- **AI Job Management**: Expert-level AI job submission and resource management
+- **Marketplace Operations**: Full marketplace participation and economic intelligence
+
+### 🏗️ **Two-Node Architecture**
+```
+AITBC Multi-Node Setup:
+├── Genesis Node (aitbc) - Port 8006 (Primary, IP: 10.1.223.40)
+├── Follower Node (aitbc1) - Port 8006 (Secondary, different IP)
+├── CLI Tool: /opt/aitbc/aitbc-cli
+├── Services: Coordinator (8001), Exchange (8000), Blockchain RPC (8006 on both nodes)
+├── AI Operations: Ollama integration, job processing, marketplace
+└── Node Synchronization: Gitea-based git pull/push (NOT SCP)
+```
+
+**Important**: Both nodes run services on the **same port (8006)** because they are on **different physical machines** with different IP addresses. This is standard distributed blockchain architecture where each node uses the same port locally but on different IPs.
+
+### 🔄 **Gitea-Based Node Synchronization**
+**Important**: Node synchronization between aitbc and aitbc1 uses **Gitea git repository**, NOT SCP file transfers.
+
+```bash
+# Sync aitbc1 from Gitea (non-interactive)
+ssh aitbc1 'cd /opt/aitbc && git pull origin main --yes --no-confirm'
+
+# Sync both nodes from Gitea (debug mode)
+cd /opt/aitbc && git pull origin main --verbose --debug
+ssh aitbc1 'cd /opt/aitbc && git pull origin main --verbose'
+
+# Push changes to Gitea (non-interactive)
+git push origin main --yes
+git push github main --yes
+
+# Check git sync status (debug mode)
+git status --verbose
+git log --oneline -5 --decorate
+ssh aitbc1 'cd /opt/aitbc && git status --verbose'
+
+# Force sync if needed (use with caution)
+ssh aitbc1 'cd /opt/aitbc && git reset --hard origin/main'
+```
+
+**Gitea Repository**: `http://gitea.bubuit.net:3000/oib/aitbc.git`
+**GitHub Mirror**: `https://github.com/oib/AITBC.git` (push only after milestones)

+
+# AITBC Node Coordinator
+
+## Purpose
+Coordinate cross-node operations, synchronize blockchain state, and manage inter-node messaging between genesis and follower nodes.
+
+## Activation
+Trigger when user requests cross-node operations: synchronization, coordination, messaging, or multi-node status checks.
+
+## Input
+```json
+{
+  "operation": "sync|status|message|coordinate|health",
+  "target_node": "genesis|follower|all",
+  "message": "string (optional for message operation)",
+  "sync_type": "blockchain|mempool|configuration|git|all (optional for sync)",
+  "timeout": "number (optional, default: 60)",
+  "force": "boolean (optional, default: false)",
+  "verify": "boolean (optional, default: true)"
+}
+```
+
+## Output
+```json
+{
+  "summary": "Cross-node operation completed successfully",
+  "operation": "sync|status|message|coordinate|health",
+  "target_node": "genesis|follower|all",
+  "nodes_status": {
+    "genesis": {
+      "status": "online|offline|degraded",

+  "issues": [],
+  "recommendations": [],
+  "confidence": 1.0,
+  "execution_time": "number",
+  "validation_status": "success|partial|failed"
+}
+```
+
+## Process
+
+### 1. Analyze
+- Validate target node connectivity using `ping` and SSH test
+- Check SSH access to remote nodes with `ssh aitbc1 "echo test"`
+- Verify blockchain service status with `systemctl status aitbc-blockchain-node`
+- Assess synchronization requirements based on sync_type parameter
+- Check P2P mesh network status with `netstat -an | grep 7070`
+- Validate git synchronization status with `git status`
+
+### 2. Plan
+- Select appropriate coordination strategy based on operation type
+- Prepare sync/messaging parameters for execution
+- Define validation criteria for operation success
+- Set fallback mechanisms for partial failures
+- Calculate timeout based on operation complexity
+- Determine if force flag is required for conflicting operations
+
+### 3. Execute
+- **For sync operations:**
+  - Execute `git pull` on both nodes for git sync
+  - Use CLI commands for blockchain state sync
+  - Restart services if force flag is set
+- **For status operations:**
+  - Execute `ssh aitbc1 "systemctl status aitbc-blockchain-node"`
+  - Check blockchain height with CLI: `./aitbc-cli chain block latest`
+  - Query mempool status with CLI: `./aitbc-cli mempool status`
+- **For message operations:**
+  - Use P2P mesh network for message delivery
+  - Track message delivery status
+- **For coordinate operations:**
+  - Execute coordinated actions across nodes
+  - Monitor execution progress
+- **For health operations:**
+  - Run comprehensive health checks
+  - Collect service metrics
+
+### 4. Validate
+- Verify node connectivity with ping and SSH
+- Check synchronization completeness by comparing block heights
+- Validate blockchain state consistency across nodes
+- Confirm messaging delivery with delivery receipts
+- Verify git synchronization with `git log --oneline -1`
+- Check service status after operations
+- Validate no service degradation occurred
+
+## Constraints
+- **MUST NOT** restart blockchain services without explicit request or force flag
+- **MUST NOT** modify node configurations without explicit approval
+- **MUST NOT** exceed 60 seconds execution time for sync operations
+- **MUST NOT** execute more than 5 parallel cross-node operations simultaneously
+- **MUST** validate SSH connectivity before remote operations
+- **MUST** handle partial failures gracefully with fallback mechanisms
+- **MUST** preserve service state during coordination operations
+- **MUST** verify git synchronization before force operations
+- **MUST** check service health before critical operations
+- **MUST** respect timeout limits (default 60s, max 120s for complex ops)
+- **MUST** validate target node existence before operations
+- **MUST** return detailed error information for all failures
+
+## Environment Assumptions
+- SSH access configured between genesis (aitbc) and follower (aitbc1) with key-based authentication
+- SSH keys located at `/root/.ssh/` for passwordless access
+- Blockchain nodes operational on both nodes via systemd services
+- P2P mesh network active on port 7070 with peer configuration
+- Git synchronization configured between nodes at `/opt/aitbc/.git`
+- CLI accessible on both nodes at `/opt/aitbc/aitbc-cli`
+- Python venv activated at `/opt/aitbc/venv/bin/python` for CLI operations
+- Systemd services: `aitbc-blockchain-node.service` on both nodes
+- Node addresses: genesis (localhost/aitbc), follower (aitbc1)
+- Git remote: `origin` at `http://gitea.bubuit.net:3000/oib/aitbc.git`
+- Log directory: `/var/log/aitbc/` for service logs
+- Data directory: `/var/lib/aitbc/` for blockchain data
+
+## Error Handling
+- SSH connectivity failures → Return connection error with affected node, attempt fallback node
+- SSH authentication failures → Return authentication error, check SSH key permissions
+- Blockchain service offline → Mark node as offline in status, attempt service restart if force flag set
+- Sync failures → Return partial sync with details, identify which sync type failed
+- Timeout during operations → Return timeout error with operation details, suggest increasing timeout
+- Git synchronization conflicts → Return conflict error, suggest manual resolution
+- P2P network disconnection → Return network error, check mesh network status
+- Service restart failures → Return service error, check systemd logs
+- Node unreachable → Return unreachable error, verify network connectivity
+- Invalid target node → Return validation error, suggest valid node names
+- Permission denied → Return permission error, check user privileges
+- CLI command failures → Return command error with stderr output
+- Partial operation success → Return partial success with completed and failed components
+
+## Example Usage Prompt
+
+```
+Sync blockchain state between genesis and follower nodes
+```
+
+```
+Check status of all nodes in the network
+```
+
+```
+Sync git repository across all nodes with force flag
+```
+
+```
+Perform health check on follower node
+```
+
+```

+```
+
+## Common AITBC Tasks
+
+### Path Migration Analysis
+```bash
+# Find all data path references
+rg "/opt/aitbc/data" --type py /opt/aitbc/production/services/
+
+# Find all config path references
+rg "/opt/aitbc/config" --type py /opt/aitbc/
+
+# Find all log path references
+rg "/opt/aitbc/logs" --type py /opt/aitbc/production/services/
+
+# Generate replacement list
+rg "/opt/aitbc/(data|config|logs)" --only-matching --type py /opt/aitbc/ | sort -u
+```
+
+### Service Configuration Audit
+```bash
+# Find all service files
+rg "aitbc.*\.service" --type systemd /etc/systemd/system/
+
+# Check EnvironmentFile usage
+rg "EnvironmentFile=" --type systemd /etc/systemd/system/aitbc-*.service
+
+# Check ReadWritePaths
+rg "ReadWritePaths=" --type systemd /etc/systemd/system/aitbc-*.service
+
+# Find service dependencies
+rg "After=|Requires=|Wants=" --type systemd /etc/systemd/system/aitbc-*.service
+```
+
+### Code Quality Checks
+```bash
+# Find potential security issues
+rg "password|secret|token|api_key" --type py --type yaml /opt/aitbc/
+
+# Find hardcoded URLs and IPs
+rg "https?://[^\s]+|[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}" --type py /opt/aitbc/
+
+# Find exception handling
+rg "except.*:" --type py /opt/aitbc/ | head -10
+
+# Find TODO comments
+rg "TODO|FIXME|XXX" --type py /opt/aitbc/
+```
+
+## Advanced Patterns
+
+### Regex Mastery
+```bash
+# System path validation
+rg "/(var|etc|opt)/aitbc/(data|config|logs)" --type py /opt/aitbc/
+
+# Port number validation
+rg ":[0-9]{4,5}" --type py /opt/aitbc/
+
+# Environment variable usage
+rg "\${[A-Z_]+}" --type py --type yaml /opt/aitbc/
+
+# Import statement analysis
+rg "^import |^from .* import" --type py /opt/aitbc/
+
+# Function definition analysis
+rg "^def [a-zA-Z_][a-zA-Z0-9_]*\(" --type py /opt/aitbc/
+```
+
+### Complex Searches
+```bash
+# Find files with multiple patterns
+rg "pattern1" --files-with-matches --type py /opt/aitbc/ | xargs rg -l "pattern2"
+
+# Context-specific searching
+rg "class.*:" -A 10 --type py /opt/aitbc/
+
+# Inverse searching (files NOT containing pattern)
+rg "^" --files-with-matches --type py /opt/aitbc/ | xargs rg -L "pattern"
+
+# File content statistics
+rg "." --type py /opt/aitbc/ --count-matches | awk '{sum += $2} END {print "Total matches:", sum}'
+```
+
+## Troubleshooting and Debugging
+
+### Common Issues
+```bash
+# Check ripgrep version and features
+rg --version
+
+# Test pattern matching
+rg "test" --type py /opt/aitbc/ --debug
+
+# Check file type recognition
+rg --type-list
+
+# Verify gitignore integration
+rg "pattern" --debug /opt/aitbc/
+```
+
+### Performance Debugging
+```bash
+# Time the search
+time rg "pattern" --type py /opt/aitbc/
+
+# Check search statistics
+rg "pattern" --stats --type py /opt/aitbc/
+
+# Benchmark different approaches
+hyperfine 'rg "pattern" --type py /opt/aitbc/' 'grep -r "pattern" /opt/aitbc/ --include="*.py"'
+```
+
+## Best Practices
+
+### Search Optimization
+1. **Use specific file types**: `--type py` instead of generic searches
+2. **Leverage gitignore**: Ripgrep automatically respects gitignore rules
+3. **Use appropriate patterns**: Word boundaries for precise matches
+4. **Limit search scope**: Use specific directories when possible
+5. **Consider alternatives**: Use `rg --files-with-matches` for file lists
+
+### Pattern Design
+1. **Be specific**: Use exact patterns when possible
+2. **Use word boundaries**: `\bword\b` for whole words
+3. **Consider context**: Use lookarounds for context-aware matching
+4. **Test patterns**: Start broad, then refine
+5. **Document patterns**: Save complex patterns for reuse
+
+### Performance Tips
+1. **Use file type filters**: `--type py` is faster than `--glob "*.py"`
+2. **Limit search depth**: `--max-depth` for large directories
+3. **Exclude unnecessary files**: Use gitignore or explicit exclusions
+4. **Use appropriate output**: `--files-with-matches` for file lists
+5. **Consider memory usage**: `--max-filesize` for large files
+

+# AITBC Systemd Git Workflow Skill
+
+## Description
+Expert skill for managing systemd service files using proper git workflow instead of scp operations. Ensures systemd configurations are always synchronized via git repository rather than direct file copying.
+
+## Core Principles
+
+### Git-Tracked Files Only
+- All systemd service files must be edited in `/opt/aitbc/systemd/` (git-tracked directory)
+- NEVER edit files directly in `/etc/systemd/system/`
+- NEVER use scp to copy systemd files between nodes
+
+### Symbolic Link Architecture
+- `/etc/systemd/system/aitbc-*.service` -> `/opt/aitbc/systemd/aitbc-*.service`
+- Symlinks ensure active systemd files always match repository
+- Changes in repository automatically reflected in active configuration
+
+## Standard Workflow
+
+### Local Changes
+1. Edit files in `/opt/aitbc/systemd/`
+2. Commit changes: `git add systemd/ && git commit -m "description"`
+3. Push to gitea: `git push`
+
+### Remote Sync (aitbc1)
+1. Pull changes: `git pull`
+2. Create/update symlinks: `/opt/aitbc/scripts/utils/link-systemd.sh`
+3. Reload systemd: `systemctl daemon-reload`
+4. Restart affected services: `systemctl restart aitbc-*`
+
+## Available Scripts
+
+### link-systemd.sh
+- Location: `/opt/aitbc/scripts/utils/link-systemd.sh`
+- Purpose: Creates symbolic links from `/etc/systemd/system/` to `/opt/aitbc/systemd/`
+- Usage: `/opt/aitbc/scripts/utils/link-systemd.sh`
+- Benefits: Automatic sync, no manual file copying needed
+
+### sync-systemd.sh
+- Location: `/opt/aitbc/scripts/sync/sync-systemd.sh`
+- Purpose: Copies repository files to active systemd (alternative to symlinks)
+- Usage: `/opt/aitbc/scripts/sync/sync-systemd.sh`
+- Note: Prefer link-systemd.sh for automatic sync
+
+## Common Issues
+
+### Git Conflicts on Remote Nodes
+**Symptom**: `git pull` fails with "local changes would be overwritten"
+
+**Resolution**:
+1. Discard local changes: `git reset --hard HEAD`
+2. Pull changes: `git pull`
+3. Re-run link-systemd.sh: `/opt/aitbc/scripts/utils/link-systemd.sh`
+
+### Broken Symlinks
+**Symptom**: Systemd service fails to load or uses old configuration
+
+**Resolution**:
+1. Verify symlinks: `ls -la /etc/systemd/system/aitbc-*`
+2. Re-create symlinks: `/opt/aitbc/scripts/utils/link-systemd.sh`
+3. Reload systemd: `systemctl daemon-reload`
+
+### SCP Usage Warning
+**Symptom**: Direct scp to `/etc/systemd/system/` breaks symlinks
+
+**Resolution**:
+1. Never use scp to `/etc/systemd/system/`
+2. Always use git workflow
+3. If scp was used, restore proper symlinks with link-systemd.sh
+
+## Verification Commands
+
+### Check Symlink Status
+```bash
+ls -la /etc/systemd/system/aitbc-*
+readlink /etc/systemd/system/aitbc-blockchain-node.service
+```
+
+### Verify Git Status
+```bash
+git status
+git diff systemd/
+```
+
+### Check Service Configuration
+```bash
+systemctl cat aitbc-blockchain-node.service
+```
+
+## Best Practices
+
+1. **Always edit in git-tracked directory**: `/opt/aitbc/systemd/`
+2. **Commit before pushing**: Ensure changes are properly committed
+3. **Pull before link-systemd.sh**: Ensure repository is up-to-date
+4. **Test locally first**: Verify changes work before syncing to remote
+5. **Document changes**: Use descriptive commit messages
+6. **Monitor logs**: Check service logs after changes
+7. **Run as root**: No sudo needed - we are root on both nodes
+
+## Memory Reference
+See memory entry `systemd-git-workflow` for detailed workflow documentation (no sudo needed - we are root on both nodes).

+}
+```
+
+## Process
+
+### 1. Diagnose Issue
+```bash
+# Collect diagnostic information
+tail -100 /var/log/aitbc/blockchain-communication-test.log > /tmp/diagnostic_logs.txt
+tail -50 /var/log/aitbc/blockchain-test-errors.txt >> /tmp/diagnostic_logs.txt
+
+# Check service status
+systemctl status aitbc-blockchain-rpc --no-pager >> /tmp/diagnostic_logs.txt
+ssh aitbc1 'systemctl status aitbc-blockchain-rpc --no-pager' >> /tmp/diagnostic_logs.txt
+
+# Check network connectivity
+ping -c 5 10.1.223.40 >> /tmp/diagnostic_logs.txt
+ping -c 5 <aitbc1-ip> >> /tmp/diagnostic_logs.txt
+
+# Check port accessibility
+netstat -tlnp | grep 8006 >> /tmp/diagnostic_logs.txt
+
+# Check blockchain status
+NODE_URL=http://10.1.223.40:8006 ./aitbc-cli blockchain info --verbose >> /tmp/diagnostic_logs.txt
+NODE_URL=http://<aitbc1-ip>:8006 ./aitbc-cli blockchain info --verbose >> /tmp/diagnostic_logs.txt
+```
+
+### 2. Analyze Root Cause
+Based on diagnostic data, identify:
+- Network connectivity issues (firewall, routing)
+- Service failures (crashes, hangs)
+- Synchronization problems (git, blockchain)
+- Resource exhaustion (CPU, memory, disk)
+- Configuration errors
+
+### 3. Execute Recovery Actions
+
+#### Connectivity Recovery
+```bash
+# Restart network services
+systemctl restart aitbc-blockchain-p2p
+ssh aitbc1 'systemctl restart aitbc-blockchain-p2p'
+
+# Check and fix firewall rules
+iptables -L -n | grep 8006
+if [ $? -ne 0 ]; then
+    iptables -A INPUT -p tcp --dport 8006 -j ACCEPT
+    iptables -A OUTPUT -p tcp --sport 8006 -j ACCEPT
+fi
+
+# Test connectivity
+curl -f -s http://10.1.223.40:8006/health
+curl -f -s http://<aitbc1-ip>:8006/health
+```
+
+#### Service Recovery
+```bash
+# Restart blockchain services
+systemctl restart aitbc-blockchain-rpc
+ssh aitbc1 'systemctl restart aitbc-blockchain-rpc'
+
+# Restart coordinator if needed
+systemctl restart aitbc-coordinator
+ssh aitbc1 'systemctl restart aitbc-coordinator'
+
+# Check service logs
+journalctl -u aitbc-blockchain-rpc -n 50 --no-pager
+```
+
+#### Synchronization Recovery
+```bash
+# Force blockchain sync
+./aitbc-cli cluster sync --all --yes
+
+# Git sync recovery
+cd /opt/aitbc
+git fetch origin main
+git reset --hard origin/main
+ssh aitbc1 'cd /opt/aitbc && git fetch origin main && git reset --hard origin/main'
+
+# Verify sync
+git log --oneline -5
+ssh aitbc1 'cd /opt/aitbc && git log --oneline -5'
+```
+
+#### Resource Recovery
+```bash
+# Clear system caches
+sync && echo 3 > /proc/sys/vm/drop_caches
+
+# Restart if resource exhausted
+systemctl restart aitbc-*
+ssh aitbc1 'systemctl restart aitbc-*'
+```
+
+### 4. Validate Recovery
+```bash
+# Run full communication test
+./scripts/blockchain-communication-test.sh --full --debug
+
+# Verify all services are healthy
+curl http://10.1.223.40:8006/health
+curl http://<aitbc1-ip>:8006/health
+curl http://10.1.223.40:8001/health
+curl http://10.1.223.40:8000/health
+
+# Check blockchain sync
+NODE_URL=http://10.1.223.40:8006 ./aitbc-cli blockchain height
+NODE_URL=http://<aitbc1-ip>:8006 ./aitbc-cli blockchain height
+```
+
+### 5. Report and Escalate
+- Document recovery actions taken
+- Provide metrics before/after recovery
+- Recommend preventive measures
+- Escalate if recovery fails or manual intervention needed
+
+## Constraints
+- Maximum recovery attempts: 3 per issue type
+- Recovery timeout: 300 seconds per action
+- Cannot restart services during peak hours (9AM-5PM local time) without confirmation
+- Must preserve blockchain data integrity
+- Cannot modify wallet keys or cryptographic material
+- Must log all recovery actions
+- Escalate to human if recovery fails after 3 attempts
+
+## Environment Assumptions
+- Genesis node IP: 10.1.223.40
+- Follower node IP: <aitbc1-ip> (replace with actual IP)
+- Both nodes use port 8006 for blockchain RPC
+- SSH access to aitbc1 configured and working
+- AITBC CLI accessible at /opt/aitbc/aitbc-cli
+- Git repository: http://gitea.bubuit.net:3000/oib/aitbc.git
+- Log directory: /var/log/aitbc/
+- Test script: /opt/aitbc/scripts/blockchain-communication-test.sh
+- Systemd services: aitbc-blockchain-rpc, aitbc-coordinator, aitbc-blockchain-p2p
+
+## Error Handling
+
+### Recovery Action Failure
+- Log specific failure reason
+- Attempt alternative recovery method
+- Increment failure counter
+- Escalate after 3 failures
+
+### Service Restart Failure
+- Check service logs for errors
+- Verify configuration files
+- Check system resources
+- Escalate if service cannot be restarted
+
+### Network Unreachable
+- Check physical network connectivity
+- Verify firewall rules
+- Check routing tables
+- Escalate if network issue persists
+
+### Data Integrity Concerns
+- Stop all recovery actions
+- Preserve current state
+- Escalate immediately for manual review
+- Do not attempt automated recovery
+
+### Timeout Exceeded
+- Stop current recovery action
+- Log timeout event
+- Attempt next recovery method
+- Escalate if all methods timeout
+
+## Example Usage Prompts
+
+### Basic Troubleshooting
+"Blockchain communication test failed on aitbc1 node. Diagnose and recover."
+
+### Specific Issue Type
+"Block synchronization lag detected (>15 blocks). Perform autonomous recovery."
+
+### Service Failure
+"aitbc-blockchain-rpc service crashed on genesis node. Restart and validate."
+
+### Network Issue
+"Cannot reach aitbc1 node on port 8006. Troubleshoot network connectivity."
+
+### Full Recovery
+"Complete blockchain communication test failed with multiple issues. Perform full autonomous recovery."
+
+### Escalation Scenario
+"Recovery actions failed after 3 attempts. Prepare escalation report with diagnostic data."
+
+## Expected Output Example

+}
+```
+
+## Model Routing
+- **Fast Model**: Use for simple, routine recoveries (service restarts, basic connectivity)
+- **Reasoning Model**: Use for complex diagnostics, root cause analysis, multi-step recovery
+- **Reasoning Model**: Use when recovery fails and escalation planning is needed
+
+## Performance Notes
+- **Diagnosis Time**: 10-30 seconds depending on issue complexity
+- **Recovery Time**: 30-120 seconds per recovery action
+- **Validation Time**: 60-180 seconds for full test suite
+- **Memory Usage**: <500MB during recovery operations
+- **Network Impact**: Minimal during diagnostics, moderate during git sync
+- **Concurrency**: Can handle single issue recovery; multiple issues should be queued
+- **Optimization**: Cache diagnostic data to avoid repeated collection
+- **Rate Limiting**: Limit service restarts to prevent thrashing
+- **Logging**: All actions logged with timestamps for audit trail

+# AITBC System Architecture Audit & Rewire Workflow
+
+This workflow performs comprehensive analysis of the AITBC codebase to ensure proper system architecture compliance and automatically rewire any incorrect paths to follow FHS standards.
+
+## Prerequisites
+
+### System Requirements
+- AITBC system deployed with proper directory structure
+- SystemD services running
+- Git repository clean of runtime files
+- Administrative access to system directories
+
+### Required Directories
+- `/var/lib/aitbc/data` - Dynamic data storage
+- `/etc/aitbc` - System configuration
+- `/var/log/aitbc` - System and application logs
+- `/opt/aitbc` - Clean repository (code only)
+
+## Workflow Phases
+
+### Phase 1: Architecture Analysis
+**Objective**: Comprehensive analysis of current system architecture compliance
+
+#### 1.1 Directory Structure Analysis
+```bash

+# Check for incorrect directory usage
+echo "Incorrect Directory Usage:"
+find /opt/aitbc -name "data" -o -name "config" -o -name "logs" 2>/dev/null || echo "✅ No incorrect directories found"
+```
+
+#### 1.2 Code Path Analysis
+```bash
+# Analyze code for incorrect path references using ripgrep
+echo "=== 2. CODE PATH ANALYSIS ==="
+
+# Find repository data references
+echo "Repository Data References:"
+rg -l "/opt/aitbc/data" --type py /opt/aitbc/ 2>/dev/null || echo "✅ No repository data references"

+
+# 3. If any hook fails, fix the issues and try again
+```
+
+### **Manual Quality Checks**
+```bash
+# Run all quality checks manually
+./venv/bin/pre-commit run --all-files
+
+# Check specific category
+./venv/bin/black --check .
+./venv/bin/flake8 .
+./venv/bin/mypy apps/coordinator-api/src/app/
+```
+

+```
+
+---
+
+## 🔧 **Troubleshooting**
+
+### **Common Issues**
+
+#### **Black Formatting Issues**
+```bash
+# Check formatting issues
+./venv/bin/black --check .
+
+# Auto-fix formatting
+./venv/bin/black .
+
+# Specific file
+./venv/bin/black --check path/to/file.py
+```
+
+#### **Import Sorting Issues**
+```bash
+# Check import sorting
+./venv/bin/isort --check-only .
+
+# Auto-fix imports
+./venv/bin/isort .
+
+# Specific file
+./venv/bin/isort path/to/file.py
+```
+
+#### **Type Checking Issues**
+```bash
+# Check type errors
+./venv/bin/mypy apps/coordinator-api/src/app/
+
+# Ignore specific errors
+./venv/bin/mypy --ignore-missing-imports apps/coordinator-api/src/app/
+
+# Show error codes
+./venv/bin/mypy --show-error-codes apps/coordinator-api/src/app/

+description: OpenClaw specialized training workflow for agent-to-agent cross-node communication via AITBC blockchain
+title: OpenClaw Cross-Node Communication Training
+version: 1.0
+---
+
+# OpenClaw Cross-Node Communication Training
+
+## Purpose
+This specialized training module teaches OpenClaw agents how to establish, verify, and utilize cross-node communication channels over the AITBC blockchain network (between genesis node `aitbc` and follower node `aitbc1`).
+
+## Learning Objectives
+1. **Agent Registration**: Register OpenClaw agents on multiple distinct blockchain nodes.
+2. **Peer Discovery**: Discover agent endpoints and IDs across the blockchain state.
+3. **Cross-Node Messaging**: Send and receive secure messages via blockchain transactions.
+4. **Task Coordination**: Delegate AI tasks from a genesis-based agent to a follower-based agent.
+5. **Event Monitoring**: Subscribe to and parse blockchain events for incoming messages.
+
+## Prerequisites
+- Completed [Stage 2 of the Mastery Plan](/OPENCLAW_AITBC_MASTERY_PLAN.md)
+- Both nodes synchronized and communicating on port 8006
+- Funded wallets on both nodes (`openclaw-trainee` and `follower-ops`)
+
+## Training Modules
+
+### Module 1: Cross-Node Agent Registration
+Agents must be registered on the blockchain to receive messages.
+
+```bash
+# Genesis Node (aitbc: 10.1.223.40)
+NODE_URL=http://10.1.223.40:8006 ./aitbc-cli agent create \
+  --name "openclaw-genesis-commander" \
+  --description "Primary coordinator agent on genesis node" \
+  --verification full \
+  --verbose
+
+# Follower Node (aitbc1: <aitbc1-ip>)
+NODE_URL=http://<aitbc1-ip>:8006 ./aitbc-cli agent create \
+  --name "openclaw-follower-worker" \
+  --description "Worker agent on follower node" \
+  --verification full \
+  --debug
+```
+
+### Module 2: Cross-Node Messaging Protocol
+Learn to format and transmit messages between the registered agents.
+
+```bash
+# Get follower agent ID
+FOLLOWER_AGENT_ID=$(NODE_URL=http://<aitbc1-ip>:8006 ./aitbc-cli agent list --output json | jq -r '.[] | select(.name=="openclaw-follower-worker") | .id')
+
+# Send instruction from genesis to follower
+NODE_URL=http://10.1.223.40:8006 ./aitbc-cli agent message \
+  --to $FOLLOWER_AGENT_ID \
+  --content "{\"cmd\":\"STATUS_REPORT\",\"priority\":\"high\"}" \
+  --verbose
+```
+
+### Module 3: Message Retrieval and Parsing
+The follower agent must listen for and decode messages.
+
+```bash
+# Retrieve messages on follower node
+NODE_URL=http://<aitbc1-ip>:8006 ./aitbc-cli agent messages \
+  --from openclaw-genesis-commander \
+  --output json
+
+# Acknowledge receipt (Follower -> Genesis)
+GENESIS_AGENT_ID=$(NODE_URL=http://10.1.223.40:8006 ./aitbc-cli agent list --output json | jq -r '.[] | select(.name=="openclaw-genesis-commander") | .id')
+
+NODE_URL=http://<aitbc1-ip>:8006 ./aitbc-cli agent message \
+  --to $GENESIS_AGENT_ID \
+  --content "{\"cmd\":\"ACK\",\"status\":\"READY\"}" \
+  --debug
+```
+
+### Module 4: Distributed Task Execution
+Combine AI job submission with cross-node agent coordination.
+
+```bash
+# Genesis instructs Follower to execute AI Job
+NODE_URL=http://10.1.223.40:8006 ./aitbc-cli agent message \
+  --to $FOLLOWER_AGENT_ID \
+  --content "{\"cmd\":\"EXECUTE_AI_JOB\",\"type\":\"inference\",\"prompt\":\"Analyze load\"}"
+
+# Follower receives, executes locally, and returns result to Genesis
+NODE_URL=http://<aitbc1-ip>:8006 ./aitbc-cli ai job submit \
+  --type inference \
+  --prompt "Analyze load" \
+  --yes
+
+NODE_URL=http://<aitbc1-ip>:8006 ./aitbc-cli agent message \
+  --to $GENESIS_AGENT_ID \
+  --content "{\"cmd\":\"JOB_COMPLETE\",\"result_id\":\"job_123\"}"
+```
+
+## Automated Training Script
+Execute the specialized training script to practice these operations autonomously.
+
+**Script Path:** `/opt/aitbc/scripts/training/openclaw_cross_node_comm.sh`
+
+```bash
+# Run the interactive training
+cd /opt/aitbc/scripts/training
+./openclaw_cross_node_comm.sh
+
+# Run in automated evaluation mode
+./openclaw_cross_node_comm.sh --auto-eval
+```
+
+## Success Validation
+An OpenClaw agent has mastered cross-node communication when it can:
+1. Parse the local state to find remote agent IDs.
+2. Construct and broadcast a valid JSON payload in an `agent message` transaction.
+3. Automatically poll or listen for response messages on the remote node.
+4. Handle network latency or temporary sync delays gracefully using retry logic.
+5. Successfully complete a round-trip (Genesis -> Follower -> Genesis) message exchange within 60 seconds.

+# Type Checking CI/CD Workflow
+
+## 🎯 **Overview**
+Comprehensive type checking workflow that ensures type safety across the AITBC codebase through automated CI/CD pipelines, coverage reporting, and quality gates.
+
+---
+
+## 📋 **Workflow Steps**
+
+### **Step 1: Local Development Type Checking**
+```bash
+# Install dependencies
+./venv/bin/pip install mypy sqlalchemy sqlmodel fastapi
+
+# Check core domain models
+./venv/bin/mypy --ignore-missing-imports --show-error-codes apps/coordinator-api/src/app/domain/job.py
+./venv/bin/mypy --ignore-missing-imports --show-error-codes apps/coordinator-api/src/app/domain/miner.py
+./venv/bin/mypy --ignore-missing-imports --show-error-codes apps/coordinator-api/src/app/domain/agent_portfolio.py
+
+# Check entire domain directory
+./venv/bin/mypy --ignore-missing-imports apps/coordinator-api/src/app/domain/
+
+# Generate coverage report
+./scripts/type-checking/check-coverage.sh
+```
+
+### **Step 2: Pre-commit Type Checking**
+```bash
+# Pre-commit hooks run automatically on commit
+git add .
+git commit -m "Add type-safe code"
+
+# Manual pre-commit run
+./venv/bin/pre-commit run mypy-domain-core
+./venv/bin/pre-commit run type-check-coverage
+```
+
+### **Step 3: CI/CD Pipeline Type Checking**
+```yaml
+# GitHub Actions workflow triggers on:
+# - Push to main/develop branches
+# - Pull requests to main/develop branches
+
+# Pipeline steps:
+# 1. Checkout code
+# 2. Setup Python 3.13
+# 3. Cache dependencies
+# 4. Install MyPy and dependencies
+# 5. Run type checking on core models
+# 6. Run type checking on entire domain
+# 7. Generate reports
+# 8. Upload artifacts
+# 9. Calculate coverage
+# 10. Enforce quality gates
+```
+
+### **Step 4: Coverage Analysis**
+```bash
+# Calculate type checking coverage
+CORE_FILES=3
+PASSING=$(./venv/bin/mypy --ignore-missing-imports apps/coordinator-api/src/app/domain/job.py apps/coordinator-api/src/app/domain/miner.py apps/coordinator-api/src/app/domain/agent_portfolio.py 2>&1 | grep -c "Success:" || echo "0")
+COVERAGE=$((PASSING * 100 / CORE_FILES))
+
+echo "Core domain coverage: $COVERAGE%"
+
+# Quality gate: 80% minimum coverage
+if [ "$COVERAGE" -ge 80 ]; then
+  echo "✅ Type checking coverage: $COVERAGE% (meets threshold)"
+else
+  echo "❌ Type checking coverage: $COVERAGE% (below 80% threshold)"
+  exit 1
+fi

+```
+
+---
+
+## 📊 **Coverage Reporting**
+
+### **Local Coverage Analysis**
+```bash
+# Run comprehensive coverage analysis
+./scripts/type-checking/check-coverage.sh
+
+# Generate detailed report
+./venv/bin/mypy --ignore-missing-imports --txt-report reports/type-check-detailed.txt apps/coordinator-api/src/app/domain/
+
+# Generate HTML report
+./venv/bin/mypy --ignore-missing-imports --html-report reports/type-check-html apps/coordinator-api/src/app/domain/
+```
+
+### **Coverage Metrics**
+```python
+# Coverage calculation components:
+# - Core domain models: 3 files (job.py, miner.py, agent_portfolio.py)
+# - Passing files: Files with no type errors
+# - Coverage percentage: (Passing / Total) * 100
+# - Quality gate: 80% minimum coverage
+
+# Example calculation:
+CORE_FILES = 3
+PASSING_FILES = 3
+COVERAGE = (3 / 3) * 100 = 100%
+```
+

+
+## 🚀 **Integration Strategy**
+
+### **Development Workflow Integration**
+```bash
+# 1. Local development
+vim apps/coordinator-api/src/app/domain/new_model.py
+
+# 2. Type checking
+./venv/bin/mypy --ignore-missing-imports apps/coordinator-api/src/app/domain/new_model.py
+
+# 3. Pre-commit validation
+git add .
+git commit -m "Add new type-safe model"  # Pre-commit runs automatically
+
+# 4. Push triggers CI/CD
+git push origin feature-branch  # GitHub Actions runs
+```
+
+### **Quality Gates**
+```yaml
+# Quality gate thresholds:
+# - Core domain coverage: >= 80%
+# - No critical type errors in core models
+# - All new code must pass type checking
+# - Type errors in existing code must be documented
+
+# Gate enforcement:
+# - CI/CD pipeline fails on low coverage
+# - Pull requests blocked on type errors
+# - Deployment requires type safety validation
+```
+
+### **Monitoring and Alerting**
+```bash
+# Type checking metrics dashboard
+curl http://localhost:3000/d/type-checking-coverage
+
+# Alert on coverage drop
+if [ "$COVERAGE" -lt 80 ]; then
+  send_alert "Type checking coverage dropped to $COVERAGE%"
+fi
+
+# Weekly coverage trends
+./scripts/type-checking/generate-coverage-trends.sh
+```
+
+---
+
+## 🎯 **Type Checking Standards**
+
+### **Core Domain Requirements**
+```python
+# Core domain models must:
+# 1. Have 100% type coverage
+# 2. Use proper type hints for all fields
+# 3. Handle Optional types correctly
+# 4. Include proper return types
+# 5. Use generic types for collections
+
+# Example:
+from typing import Any, Dict, Optional
+from datetime import datetime
+from sqlmodel import SQLModel, Field
+
+class Job(SQLModel, table=True):
+    id: str = Field(primary_key=True)
+    name: str
+    payload: Dict[str, Any] = Field(default_factory=dict)
+    created_at: datetime = Field(default_factory=datetime.utcnow)
+    updated_at: Optional[datetime] = None
+```
+
+### **Service Layer Standards**
+```python
+# Service layer must:
+# 1. Type all method parameters
+# 2. Include return type annotations
+# 3. Handle exceptions properly
+# 4. Use dependency injection types
+# 5. Document complex types
+
+# Example:
+from typing import List, Optional
+from sqlmodel import Session
+
+class JobService:
+    def __init__(self, session: Session) -> None:
+        self.session = session
+    
+    def get_job(self, job_id: str) -> Optional[Job]:
+        """Get a job by ID."""
+        return self.session.get(Job, job_id)
+    
+    def create_job(self, job_data: JobCreate) -> Job:
+        """Create a new job."""
+        job = Job.model_validate(job_data)
+        self.session.add(job)
+        self.session.commit()
+        self.session.refresh(job)
+        return job
+```
+
+### **API Router Standards**
+```python
+# API routers must:
+# 1. Type all route parameters
+# 2. Use Pydantic models for request/response
+# 3. Include proper HTTP status types
+# 4. Handle error responses
+# 5. Document complex endpoints
+
+# Example:
+from fastapi import APIRouter, HTTPException, Depends
+from typing import List
+
+router = APIRouter(prefix="/jobs", tags=["jobs"])
+
+@router.get("/", response_model=List[JobRead])
+async def get_jobs(
+    skip: int = 0,
+    limit: int = 100,
+    session: Session = Depends(get_session)
+) -> List[JobRead]:
+    """Get all jobs with pagination."""
+    jobs = session.exec(select(Job).offset(skip).limit(limit)).all()
+    return jobs
+```
+
+---

+./venv/bin/mypy --ignore-missing-imports apps/coordinator-api/src/app/routers/
+```
+
+### **Phase 4: Strict Mode (Future)**
+```toml
+# pyproject.toml
+[tool.mypy]
+check_untyped_defs = true
+disallow_untyped_defs = true
+no_implicit_optional = true

+```
+
+---
+
+## 🔧 **Troubleshooting**
+
+### **Common Type Errors**
+
+#### **Missing Import Error**
+```bash
+# Error: Name "uuid4" is not defined
+# Solution: Add missing import
+from uuid import uuid4
+```
+
+#### **SQLModel Field Type Error**
+```bash
+# Error: No overload variant of "Field" matches
+# Solution: Use proper type annotations
+payload: Dict[str, Any] = Field(default_factory=dict)
+```
+
+#### **Optional Type Error**
+```bash
+# Error: Incompatible types in assignment
+# Solution: Use Optional type annotation
+updated_at: Optional[datetime] = None
+```
+
+#### **Generic Type Error**
+```bash
+# Error: Dict entry has incompatible type
+# Solution: Use proper generic types
+results: Dict[str, Any] = {}
+```
+
+### **Performance Optimization**
+```bash
+# Cache MyPy results
+./venv/bin/mypy --incremental apps/coordinator-api/src/app/
+
+# Use daemon mode for faster checking
+./venv/bin/mypy --daemon apps/coordinator-api/src/app/
+
+# Limit scope for large projects
+./venv/bin/mypy apps/coordinator-api/src/app/domain/ --exclude apps/coordinator-api/src/app/domain/legacy/
+```
+
+### **Configuration Issues**
+```bash
+# Check MyPy configuration
+./venv/bin/mypy --config-file pyproject.toml apps/coordinator-api/src/app/
+
+# Show configuration
+./venv/bin/mypy --show-config
+
+# Debug configuration
+./venv/bin/mypy --verbose apps/coordinator-api/src/app/
+```

-# AITBC Setup Guide
-
-## Quick Setup (New Host)
-
-Run this single command on any new host to install AITBC:
-
-```bash
-sudo bash <(curl -sSL https://raw.githubusercontent.com/oib/aitbc/main/setup.sh)
-```
-
-Or clone and run manually:
-
-```bash
-sudo git clone https://gitea.bubuit.net/oib/aitbc.git /opt/aitbc
-cd /opt/aitbc
-sudo chmod +x setup.sh
-sudo ./setup.sh
-```
-
-## What the Setup Script Does
-
-1. **Prerequisites Check**
-   - Verifies Python 3.13.5+, pip3, git, systemd
-   - Checks for root privileges
-
-2. **Repository Setup**
-   - Clones AITBC repository to `/opt/aitbc`
-   - Handles multiple repository URLs for reliability
-
-3. **Virtual Environments**
-   - Creates Python venvs for each service
-   - Installs dependencies from `requirements.txt` when available
-   - Falls back to core dependencies if requirements missing
-
-4. **Runtime Directories**
-   - Creates standard Linux directories:
-     - `/var/lib/aitbc/keystore/` - Blockchain keys
-     - `/var/lib/aitbc/data/` - Database files  
-     - `/var/lib/aitbc/logs/` - Application logs
-     - `/etc/aitbc/` - Configuration files
-   - Sets proper permissions and ownership
-
-5. **Systemd Services**
-   - Installs service files to `/etc/systemd/system/`
-   - Enables auto-start on boot
-   - Provides fallback manual startup
-
-6. **Service Management**
-   - Creates `/opt/aitbc/start-services.sh` for manual control
-   - Creates `/opt/aitbc/health-check.sh` for monitoring
-   - Sets up logging to `/var/log/aitbc-*.log`
-
-## Runtime Directories
-
-AITBC uses standard Linux system directories for runtime data:
-
-```
-/var/lib/aitbc/
-├── keystore/     # Blockchain private keys (700 permissions)
-├── data/         # Database files (.db, .sqlite)
-└── logs/         # Application logs
-
-/etc/aitbc/       # Configuration files
-/var/log/aitbc/   # System logging (symlink)
-```
-
-### Security Notes
-- **Keystore**: Restricted to root/aitbc user only
-- **Data**: Writable by services, readable by admin
-- **Logs**: Rotated automatically by logrotate
-
-## Service Endpoints
-
-| Service | Port | Health Endpoint |
-|---------|------|----------------|
-| Wallet API | 8003 | `http://localhost:8003/health` |
-| Exchange API | 8001 | `http://localhost:8001/api/health` |
-| Coordinator API | 8000 | `http://localhost:8000/health` |
-| Blockchain RPC | 8545 | `http://localhost:8545` |
-
-## Management Commands
-
-```bash
-# Check service health
-/opt/aitbc/health-check.sh
-
-# Restart all services
-/opt/aitbc/start-services.sh
-
-# View logs (new standard locations)
-tail -f /var/lib/aitbc/logs/aitbc-wallet.log
-tail -f /var/lib/aitbc/logs/aitbc-coordinator.log
-tail -f /var/lib/aitbc/logs/aitbc-exchange.log
-
-# Check keystore
-ls -la /var/lib/aitbc/keystore/
-
-# Systemd control
-systemctl status aitbc-wallet
-systemctl restart aitbc-coordinator-api
-systemctl stop aitbc-exchange-api
-```
-
-## Troubleshooting
-
-### Services Not Starting
-1. Check logs: `tail -f /var/lib/aitbc/logs/aitbc-*.log`
-2. Verify ports: `netstat -tlnp | grep ':800'`
-3. Check processes: `ps aux | grep python`
-4. Verify runtime directories: `ls -la /var/lib/aitbc/`
-
-### Missing Dependencies
-The setup script handles missing `requirements.txt` files by installing core dependencies:
-- fastapi
-- uvicorn
-- pydantic
-- httpx
-- python-dotenv
-
-### Port Conflicts
-Services use these default ports. If conflicts exist:
-1. Kill conflicting processes: `kill <pid>`
-2. Modify service files to use different ports
-3. Restart services
-
-## Development Mode
-
-For development with manual control:
-
-```bash
-cd /opt/aitbc/apps/wallet
-source .venv/bin/activate
-python simple_daemon.py
-
-cd /opt/aitbc/apps/exchange
-source .venv/bin/activate
-python simple_exchange_api.py
-
-cd /opt/aitbc/apps/coordinator-api/src
-source ../.venv/bin/activate
-python -m uvicorn app.main:app --host 0.0.0.0 --port 8000
-```
-
-## Production Considerations
-
-For production deployment:
-1. Configure proper environment variables
-2. Set up reverse proxy (nginx)
-3. Configure SSL certificates
-4. Set up log rotation
-5. Configure monitoring and alerts
-6. Use proper database setup (PostgreSQL/Redis)
