Phase 1: Foundation & Authentication - COMPLETED

Date: 2026-05-09
Status: ✅ Complete and tested

What Was Implemented

1. Project Structure

Created new modules under api/agnet/ and config/:

• config/error_codes.py - Error code enums
• config/settings.py - Pydantic settings with env vars
• api/agnet/auth.py - Service token middleware
• api/agnet/models.py - Pydantic request/response models
• api/agnet/validators.py - Sensitive field scanner
• api/agnet/router.py - Main router with health check
• api/agnet/idempotency.py - Redis-based idempotency cache

2. Key Features Implemented

Service Token Authentication

• Pre-shared bearer token validation (Phase 1-4 approach)
• Token stored in HEICODE_SERVICE_TOKEN environment variable
• Returns 401 with INVALID_TOKEN error code on failure

Header Extraction

• X-Correlation-Id - Request correlation ID
• X-User-Id - End user ID
• X-Binding-Scope - Resource scope
• Idempotency-Key - For idempotent operations

Sensitive Field Scanner

• Recursive scan of request payloads
• Detects keywords: password, token, secret, api_key, private_key, etc.
• Allows vault references (vault:...) but rejects plaintext secrets
• Returns 422 with RESOURCE_GRANT_SECRET_REJECTED on violation

Idempotency Cache

• Redis-based with 24h TTL
• Key format: idempotency:{key}
• Graceful fallback if Redis unavailable

Health Check Endpoint

• GET /api/agnet/health
• Requires service token authentication
• Returns service status and version

3. Test Results

✅ Test 1: Valid token

• Status: 200 OK
• Response: {"success": true, "data": {"status": "healthy", ...}}

✅ Test 2: Invalid token

• Status: 401 Unauthorized
• Error code: INVALID_TOKEN

✅ Test 3: No token

• Status: 401 Unauthorized
• Error: "Not authenticated"

✅ Test 4: Sensitive field detection

• Correctly rejects payloads with password, token, etc.
• Allows vault references

✅ Test 5: Redis idempotency cache

• Successfully connects to Redis
• Can store and retrieve cached responses

Integration with Existing Code

• ✅ Router registered in app.py (lines 42-43)
• ✅ No changes to existing /agents/* endpoints
• ✅ Dependencies already in requirements.txt (redis, pydantic-settings)
• ✅ Settings class ignores extra env vars from existing .env file

Acceptance Criteria Met

• Service token middleware blocks unauthorized requests (401)
• Headers (correlation_id, user_id, binding_scope) extracted correctly
• Sensitive field scanner detects all keywords
• Redis idempotency cache working
• Health check endpoint returns 200
• No changes to existing endpoints
• Backward compatibility maintained

Next Steps

Phase 2: Core Deployment Endpoints (5-7 days)

• Database models (deployments, agent_instances tables)
• POST /api/agnet/deployments (create)
• GET /api/agnet/deployments (list)
• GET /api/agnet/deployments/{id} (details)
• POST /api/agnet/deployments/{id}/stop (stop)
• Validation logic (provider enum, approval check, model_id validation)
• Deployment orchestrator service

Notes

• Service token is currently pre-shared (dev-token-change-in-production)
• Phase 5 will migrate to AKS Workload Identity
• Redis is optional - graceful fallback if unavailable
• All code follows existing project style and conventions
