feat: Add comprehensive integration tests for bulk-ingest message sync

[khaliqgant]

Comprehensive integration test suite for the bulk-ingest message synchronization
feature with support for testing against live cloud server and PostgreSQL.

Changes

• test/cloud/bulk-ingest.integration.test.ts (957 lines)

  • 25+ integration test cases covering:
    • Basic message sync (single, small batch, empty batch)
    • Batch size strategies (small 10, medium 150, max 500, oversized rejection)
    • Deduplication via workspace_id + original_id constraint
    • Message content types (JSONB data, payload_meta, broadcast, threads)
    • Authentication (missing, invalid, malformed tokens)
    • Workspace linking (auto-link via repoFullName, existing link)
    • Concurrent sync scenarios
    • Pool health and statistics endpoint
    • Retention policy enforcement
  • Proper test helpers for daemon/user/workspace creation
  • Timeout and teardown management

• src/cloud/api/test-helpers.ts (832 lines)

  • New test-only API routes:
    • POST /api/test/create-user - Create test user without OAuth
    • POST /api/test/create-daemon - Create test daemon
    • POST /api/test/create-workspace - Create test workspace
    • POST /api/test/create-daemon-with-workspace - Linked daemon
    • POST /api/test/sync-messages - Send test messages to sync endpoint
    • POST /api/test/get-agent-messages - Retrieve synced messages
  • Disabled in production (NODE_ENV=production check)
  • Proper error handling and JSON response formatting

• vitest.config.ts

  • Updated include pattern to cover test/cloud/** integration tests
  • Maintains src/**/*.test.ts unit test coverage

Testing

Run integration tests with:

npm run test:integration

Or with docker:

docker compose -f docker-compose.test.yml run test-runner

Tests require:

• Cloud server running on http://localhost:3100 (configurable via CLOUD_API_URL)
• PostgreSQL database configured
• TEST_TIMEOUT environment variable (default: 30s)

Acceptance Criteria

✅ Integration tests created with 25+ comprehensive test cases
✅ Test helper endpoints for daemon/workspace/user creation
✅ Full coverage of batch strategies, deduplication, auth, workspace linking
✅ Tests runnable with npm run test:integration
✅ All TypeScript compilation errors resolved
✅ Production safety: test endpoints disabled in production
