-# Ollama GPU Provider Test Skill
+# Ollama GPU Provider Complete Test Workflow

-This skill runs an end-to-end client → coordinator → GPU miner → receipt flow using an Ollama prompt.
+This skill provides a comprehensive test workflow for verifying the entire Ollama GPU inference pipeline from client job submission through blockchain transaction recording.

 ## Overview

-The test submits a prompt (default: "hello") to the coordinator via the host proxy, waits for completion, and verifies that the job result and signed receipt are returned.
+The complete flow includes:
+1. Client submits inference job to coordinator
+2. GPU miner picks up and processes job via Ollama
+3. Miner submits result with metrics
+4. Coordinator generates signed receipt
+5. Client processes payment to miner
+6. Transaction recorded on blockchain

 ## Prerequisites

- Host GPU miner running and registered (RTX 4060 Ti + Ollama)
- Incus proxy forwarding `127.0.0.1:18000` → container `127.0.0.1:8000`
- Coordinator running in container (`coordinator-api.service`)
- Receipt signing key configured in `/opt/coordinator-api/src/.env`
-
-## Test Command
+### Required Services
+- Coordinator API running on port 18000
+- GPU miner service running (`aitbc-host-gpu-miner.service`)
+- Ollama service running on port 11434
+- Blockchain node accessible (local: 19000 or remote: aitbc.keisanki.net/rpc)
+- Home directory wallets configured

+### Configuration
 ```bash
-python3 cli/test_ollama_gpu_provider.py --url http://127.0.0.1:18000 --prompt "hello"
+# Verify services
+./scripts/aitbc-cli.sh health
+curl -s http://localhost:11434/api/tags
+systemctl status aitbc-host-gpu-miner.service
 ```

-## Expected Outcome
+## Test Options

- Job reaches `COMPLETED`
- Output returned from Ollama
- Receipt present with a `receipt_id`
+### Option 1: Basic API Test (No Payment)
+```bash
+# Simple test without blockchain
+python3 cli/test_ollama_gpu_provider.py \
+  --url http://127.0.0.1:18000 \
+  --prompt "What is the capital of France?" \
+  --model llama3.2:latest
+```

-## Notes
+### Option 2: Complete Workflow with Home Directory Users
+```bash
+# Full test with payment and blockchain
+cd /home/oib/windsurf/aitbc/home
+python3 test_ollama_blockchain.py
+```

- Use `--timeout` to allow longer runs for large models.
- If the receipt is missing, verify `receipt_signing_key_hex` is set and restart the coordinator.
+### Option 3: Manual Step-by-Step
+```bash
+# 1. Submit job
+cd /home/oib/windsurf/aitbc/home
+job_id=$(../cli/client.py submit inference \
+  --prompt "What is the capital of France?" \
+  --model llama3.2:latest | grep "Job ID" | awk '{print $3}')
+
+# 2. Monitor progress
+watch -n 2 "../cli/client.py status $job_id"
+
+# 3. Get result and receipt
+curl -H "X-Api-Key: REDACTED_CLIENT_KEY" \
+  "http://127.0.0.1:18000/v1/jobs/$job_id/result" | python3 -m json.tool
+
+# 4. Process payment (manual)
+miner_addr=$(cd miner && python3 wallet.py address | grep Address | awk '{print $3}')
+amount=0.05  # Based on receipt
+cd client && python3 wallet.py send $amount $miner_addr "Payment for job $job_id"
+
+# 5. Record earnings
+cd ../miner && python3 wallet.py earn $amount --job $job_id --desc "Inference job"
+
+# 6. Check blockchain
+curl -s "http://aitbc.keisanki.net/rpc/transactions" | \
+  python3 -c "import sys, json; data=json.load(sys.stdin); \
+    [print(f\"TX: {t['tx_hash']} - Block: {t['block_height']}\") \
+    for t in data.get('transactions', []) \
+    if 'receipt_id' in str(t.get('payload', {}))]"
+```
+
+## Expected Results
+
+| Step | Expected Output | Verification |
+|------|----------------|--------------|
+| Job Submission | Job ID returned, state = QUEUED | `client.py status` shows job |
+| Processing | State → RUNNING, miner assigned | Miner logs show job pickup |
+| Completion | State = COMPLETED, output received | Result endpoint returns data |
+| Receipt | Generated with price > 0 | Receipt has valid signature |
+| Payment | Client balance ↓, miner ↑ | Wallet balances update |
+| Blockchain | Transaction recorded | TX hash searchable |
+
+## Monitoring Commands
+
+```bash
+# Real-time miner logs
+sudo journalctl -u aitbc-host-gpu-miner.service -f
+
+# Recent receipts
+curl -H "X-Api-Key: REDACTED_CLIENT_KEY" \
+  http://127.0.0.1:18000/v1/explorer/receipts?limit=5
+
+# Wallet balances
+cd /home/oib/windsurf/aitbc/home && \
+  echo "Client:" && cd client && python3 wallet.py balance && \
+  echo "Miner:" && cd ../miner && python3 wallet.py balance
+
+# Blockchain transactions
+curl -s http://aitbc.keisanki.net/rpc/transactions | python3 -m json.tool
+```
+
+## Troubleshooting
+
+### Job Stuck in QUEUED
+```bash
+# Check miner service
+systemctl status aitbc-host-gpu-miner.service
+
+# Restart if needed
+sudo systemctl restart aitbc-host-gpu-miner.service
+
+# Check miner registration
+curl -H "X-Api-Key: REDACTED_ADMIN_KEY" \
+  http://127.0.0.1:18000/v1/admin/miners
+```
+
+### No Receipt Generated
+```bash
+# Verify receipt signing key
+grep receipt_signing_key_hex /opt/coordinator-api/src/.env
+
+# Check job result for receipt
+curl -H "X-Api-Key: REDACTED_CLIENT_KEY" \
+  http://127.0.0.1:18000/v1/jobs/<job_id>/result | jq .receipt
+```
+
+### Payment Issues
+```bash
+# Check wallet addresses
+cd /home/oib/windsurf/aitbc/home/client && python3 wallet.py address
+cd /home/oib/windsurf/aitbc/home/miner && python3 wallet.py address
+
+# Verify transaction
+python3 wallet.py transactions
+```
+
+### Blockchain Not Recording
+```bash
+# Check node availability
+curl -s http://aitbc.keisanki.net/rpc/health
+
+# Search for receipt
+curl -s "http://aitbc.keisanki.net/rpc/transactions" | \
+  grep <receipt_id>
+```

+description: Workflow for managing and documenting issues from current to resolved
+---
+
+# Issue Management Workflow
+
+This workflow handles the lifecycle of issues from identification to resolution and archival.
+
+## Prerequisites
+
+// turbo
+- Ensure you have write access to the docs directory
+- Check if the issue is already tracked in docs/currentissue.md
+
+## Steps
+
+### 1. Identify New Issue
+```bash
+# Check if currentissue.md already exists and has content
+cat /home/oib/windsurf/aitbc/docs/currentissue.md
+```
+
+### 2. Document Issue in currentissue.md
+If tracking a new issue:
+- Add section with clear, descriptive title
+- Include date, status, description
+- List affected components
+- Document attempted fixes
+- Update status regularly
+
+### 3. Monitor Progress
+- Update the issue status as work progresses
+- Add resolution details when fixed
+- Include code changes, configuration updates, etc.
+
+### 4. When Issue is Resolved
+```bash
+# Move to issues folder with machine-readable name
+mv /home/oib/windsurf/aitbc/docs/currentissue.md \
+   /home/oib/windsurf/aitbc/docs/issues/YYYY-MM-DD_brief-description.md
+
+# Example:
+# mv docs/currentissue.md docs/issues/2026-01-29_cross-site-sync-resolved.md
+```
+
+### 5. Create New Empty currentissue.md
+```bash
+# Create fresh currentissue.md
+cat > /home/oib/windsurf/aitbc/docs/currentissue.md << 'EOF'
+# Current Issues
+
+*No current issues to report.*
+
+---
+
+## Usage Guidelines
+
+When tracking a new issue:
+1. Add a new section with a descriptive title
+2. Include the date and current status
+3. Describe the issue, affected components, and any fixes attempted
+4. Update status as progress is made
+5. Once resolved, move this file to `docs/issues/` with a machine-readable name
+
+## Recent Resolved Issues
+
+See `docs/issues/` for resolved issues and their solutions.
+EOF
+```
+
+## Naming Convention for Archived Issues
+
+Use format: `YYYY-MM-DD_brief-description.md`
+- Date: Year-Month-Day of resolution
+- Description: Brief, lowercase, hyphen-separated summary
+- Examples:
+  - `2026-01-29_cross-site-sync-resolved.md`
+  - `2026-01-15_pytest-warnings-fixed.md`
+  - `2026-01-10_database-migration-issue.md`
+
+## Best Practices
+
+1. **For Complex Issues**: Use `docs/currentissue.md` as the central tracking document
+2. **Regular Updates**: Update status daily for active issues
+3. **Detailed Resolution**: Document root cause and solution clearly
+4. **Cross-References**: Link to related code changes, PRs, or documentation
+5. **Archive Promptly**: Move resolved issues within 24 hours of resolution
+
+## Integration with Other Workflows
+
+- Use with `/docs` workflow to keep documentation current
+- Reference resolved issues in `docs/done.md`
+- Link technical details in `docs/reports/` as needed
+
+## Memory Aid
+
+Remember: For hard-to-track or complex issues spanning multiple components, always use `docs/currentissue.md` as the single source of truth for current status and resolution progress.

+```bash
+# Execute the full workflow test
+cd /home/oib/windsurf/aitbc/home
+python3 test_ollama_blockchain.py
+```
+
+### 3. Verify Results
+The test will display:
+- Initial wallet balances
+- Job submission and ID
+- Real-time job progress
+- Inference result from Ollama
+- Receipt details with pricing
+- Payment confirmation
+- Final wallet balances
+- Blockchain transaction status
+
+### 4. Manual Verification (Optional)
+```bash
+# Check recent receipts
+curl -H "X-Api-Key: REDACTED_CLIENT_KEY" \
+  http://127.0.0.1:18000/v1/explorer/receipts?limit=3
+
+# Verify blockchain transaction
+curl -s http://aitbc.keisanki.net/rpc/transactions | \
+  python3 -c "import sys, json; data=json.load(sys.stdin); \
+    [print(f\"TX: {t['tx_hash']} - Block: {t['block_height']}\") \
+    for t in data.get('transactions', [])[-5:]]"
+```
+
+## Expected Output

 # Current Issues

-## Cross-Site Synchronization - PARTIALLY IMPLEMENTED
+*No current issues to report.*

-### Date
-2026-01-29
+---

-### Status
-**PARTIALLY IMPLEMENTED** - Cross-site sync is running on all nodes. Transaction propagation works. Block import endpoint exists but has a database constraint issue with transaction import.
+## Usage Guidelines

-### Description
-Cross-site synchronization has been integrated into all blockchain nodes. The sync module detects height differences between nodes and can propagate transactions via RPC.
+When tracking a new issue:
+1. Add a new section with a descriptive title
+2. Include the date and current status
+3. Describe the issue, affected components, and any fixes attempted
+4. Update status as progress is made
+5. Once resolved, move this file to `docs/issues/` with a machine-readable name

-### Components Affected
- `/src/aitbc_chain/main.py` - Main blockchain node process
- `/src/aitbc_chain/cross_site.py` - Cross-site sync module (implemented but not integrated)
- All three blockchain nodes (localhost Node 1 & 2, remote Node 3)
+## Recent Resolved Issues

-### What Was Fixed
-1. **main.py integration**: Removed problematic `AbstractAsyncContextManager` type annotation and simplified the code structure
-2. **Cross-site sync module**: Integrated into all three nodes and now starts automatically
-3. **Config settings**: Added `cross_site_sync_enabled`, `cross_site_remote_endpoints`, `cross_site_poll_interval` inside the `ChainSettings` class
-4. **URL paths**: Fixed RPC endpoint paths (e.g., `/head` instead of `/rpc/head` for remote endpoints that already include `/rpc`)
-
-### Current Status
- **All nodes**: Running with cross-site sync enabled
- **Transaction sync**: Working - mempool transactions can propagate between sites
- **Block sync**: ✅ FULLY IMPLEMENTED - `/blocks/import` endpoint works with transactions
- **Height difference**: Nodes maintain independent chains (local: 771153, remote: 40324)
- **Status**: Block import with transactions now working after nginx routing fix
-
-### Resolved Issues
-Block synchronization transaction import issue has been **FIXED**:
- `/blocks/import` POST endpoint is functional and deployed on all nodes
- Endpoint validates block hashes, parent blocks, and prevents conflicts
- ✅ Can import blocks with and without transactions
- ✅ Transaction data properly saved to database
- Root cause: nginx was routing to wrong port (8082 instead of 8081)
- Fix: Updated nginx config to route to correct blockchain-rpc-2 service
-
-### Block Sync Implementation Progress
-
-1. **✅ Block Import Endpoint Created** - `/src/aitbc_chain/rpc/router.py`:
-   - Added `@router.post("/blocks/import")` endpoint
-   - Implemented block validation (hash, parent, existence checks)
-   - Added transaction and receipt import logic
-   - Returns status: "imported", "exists", or error details
-
-2. **✅ Cross-Site Sync Updated** - `/src/aitbc_chain/sync/cross_site.py`:
-   - Modified `import_block()` to call `/rpc/blocks/import`
-   - Formats block data correctly for import
-   - Handles import success/failure responses
-
-3. **✅ Runtime Error Fixed**:
-   - Moved inline imports (hashlib, datetime, config) to top of file
-   - Added proper error logging and exception handling
-   - Fixed indentation issues in the function
-   - Endpoint now returns proper validation responses
-
-4. **✅ Transaction Import Fixed**:
-   - Root cause was nginx routing to wrong port (8082 instead of 8081)
-   - Updated transaction creation to use constructor with all fields
-   - Server rebooted to clear all caches
-   - Nginx config fixed to route to blockchain-rpc-2 on port 8081
-   - Verified transaction is saved correctly with all fields
-
-5. **⏳ Future Enhancements**:
-   - Add proposer signature validation
-   - Implement fork resolution for conflicting chains
-   - Add authorized node list configuration
-
-### What Works Now
- Cross-site sync loop runs every 10 seconds
- Remote endpoint polling detects height differences
- Transaction propagation between sites via mempool sync
- ✅ Block import endpoint functional with validation
- ✅ Blocks with and without transactions can be imported between sites via RPC
- ✅ Transaction data properly saved to database
- Logging shows sync activity in journalctl
-
-### Files Modified
- `/src/aitbc_chain/main.py` - Added cross-site sync integration
- `/src/aitbc_chain/cross_site.py` - Fixed URL paths, updated to use /blocks/import endpoint
- `/src/aitbc_chain/config.py` - Added sync settings inside ChainSettings class (all nodes)
- `/src/aitbc_chain/rpc/router.py` - Added /blocks/import POST endpoint with validation
-
-### Next Steps
-1. **Monitor Block Synchronization**:
-   - Watch logs for successful block imports with transactions
-   - Verify cross-site sync is actively syncing block heights
-   - Monitor for any validation errors or conflicts
-
-2. **Future Enhancements**:
-   - Add proposer signature validation for security
-   - Implement fork resolution for conflicting chains
-   - Add sync metrics and monitoring dashboard
-
-**Status**: ✅ COMPLETE - Block import with transactions working
-**Impact**: Full cross-site block synchronization now available
-**Resolution**: Server rebooted, nginx routing fixed to port 8081

+   - Modified `import_block()` to call `/rpc/blocks/import`
+   - Formats block data correctly for import
+   - Handles import success/failure responses
+
+3. **✅ Runtime Error Fixed**:
+   - Moved inline imports (hashlib, datetime, config) to top of file
+   - Added proper error logging and exception handling
+   - Fixed indentation issues in the function
+   - Endpoint now returns proper validation responses
+
+4. **✅ Transaction Import Fixed**:
+   - Root cause was nginx routing to wrong port (8082 instead of 8081)
+   - Updated transaction creation to use constructor with all fields
+   - Server rebooted to clear all caches
+   - Nginx config fixed to route to blockchain-rpc-2 on port 8081
+   - Verified transaction is saved correctly with all fields
+
+5. **⏳ Future Enhancements**:
+   - Add proposer signature validation
+   - Implement fork resolution for conflicting chains
+   - Add authorized node list configuration
+
+### What Works Now
+- Cross-site sync loop runs every 10 seconds
+- Remote endpoint polling detects height differences
+- Transaction propagation between sites via mempool sync
+- ✅ Block import endpoint functional with validation
+- ✅ Blocks with and without transactions can be imported between sites via RPC
+- ✅ Transaction data properly saved to database
+- Logging shows sync activity in journalctl
+
+### Files Modified
+- `/src/aitbc_chain/main.py` - Added cross-site sync integration
+- `/src/aitbc_chain/cross_site.py` - Fixed URL paths, updated to use /blocks/import endpoint
+- `/src/aitbc_chain/config.py` - Added sync settings inside ChainSettings class (all nodes)
+- `/src/aitbc_chain/rpc/router.py` - Added /blocks/import POST endpoint with validation
+
+### Next Steps
+1. **Monitor Block Synchronization**:
+   - Watch logs for successful block imports with transactions
+   - Verify cross-site sync is actively syncing block heights
+   - Monitor for any validation errors or conflicts
+
+2. **Future Enhancements**:
+   - Add proposer signature validation for security
+   - Implement fork resolution for conflicting chains
+   - Add sync metrics and monitoring dashboard
+
+**Status**: ✅ COMPLETE - Block import with transactions working
+**Impact**: Full cross-site block synchronization now available
+**Resolution**: Server rebooted, nginx routing fixed to port 8081
