🎨 Feature Highlights

1. Manual Re-enqueue

Re-queue failed jobs for retry:

npm run oracle:rescue re-enqueue 12345 \
  --operator alice \
  --reason "RPC recovered, retrying"

2. Force Submit

Manually compute and submit randomness:

npm run oracle:rescue force-submit 42 req_abc123 \
  --operator bob \
  --reason "All retries exhausted, manual submission"

3. Force Fail

Remove invalid/malicious requests:

npm run oracle:rescue force-fail 12345 \
  --operator alice \
  --reason "Invalid raffle ID - malicious request"

4. Audit Trail

Complete logging of all operations:

  • Timestamp
  • Action type
  • Raffle ID & Request ID
  • Operator name
  • Reason
  • Result & details

🔒 Safety Features

  • ✅ Idempotency: Checks if raffle already finalized
  • ✅ Validation: Input validation before execution
  • ✅ Audit Trail: Complete logging of all operations
  • ✅ Operator Tracking: All operations require operator ID
  • ✅ Reason Required: All operations require documented reason
  • ✅ Error Handling: Graceful failures with detailed messages

🚀 Quick Start Guide

For Operators

  1. Check failed jobs:

    npm run oracle:rescue list-failed

  2. Re-enqueue if transient error:

    npm run oracle:rescue re-enqueue <jobId> \
  --operator <your-name> \
  --reason "<why>"

  3. Force submit if urgent:

    npm run oracle:rescue force-submit <raffleId> <requestId> \
  --operator <your-name> \
  --reason "<why>"

  4. View audit logs:

    npm run oracle:rescue logs --limit 50

For Developers

  1. Install dependencies:

    cd oracle
pnpm install

  2. Run tests:

    node test-rescue-cli.js
npm test src/rescue/rescue.service.spec.ts

  3. Start application:

    npm run start:dev

  4. Test API:

    curl http://localhost:3003/rescue/failed-jobs

Scenario 3: Malicious Request

# Remove from queue
npm run oracle:rescue force-fail <jobId> \
  --operator <name> \
  --reason "Invalid raffle ID - malicious request"

Scenario 4: Audit Review

# Check recent operations
npm run oracle:rescue logs --limit 50

# Check specific raffle
npm run oracle:rescue logs --raffle 42
