Monorepo Packages +Created `packages/` directory for shared code. Hooks-core and redux-slices are now available to other frontends via npm workspaces. + +**Alternative considered:** Separate npm registry packages - deferred until stabilization. + +### 4.

Multiple Backend Implementations +```typescript +// HTTP Implementation (default) +const services = { + projectService: new DefaultProjectServiceAdapter('/api'), + workspaceService: new DefaultWorkspaceServiceAdapter('/api'), + // ... +} + +// Mock Implementation (testing) +const mockServices = { + projectService: new MockProjectServiceAdapter(), + workspaceService: new MockWorkspaceServiceAdapter(), + // ... +} + +// Future: GraphQL Implementation +const graphqlServices = { + projectService: new GraphQLProjectServiceAdapter(), + workspaceService: new GraphQLWorkspaceServiceAdapter(), + // ... +} +``` + +### 2. Easy Testing +```typescript +test('useProject loads projects', async () => { + const mockServices = { projectService: new MockProjectServiceAdapter() } + + render( + + + + ) + + // No backend server, no API mocking needed +}) +``` + +### 3. Environment-Specific Adapters +```typescript +// Production +const services = new DefaultProjectServiceAdapter('/api') + +// Development +const services = new MockProjectServiceAdapter() + +// Staging +const services = new DefaultProjectServiceAdapter('https://staging-api.example.com') +``` + +### 4. Type-Safe Service Contracts +```typescript +interface IProjectServiceAdapter { + listProjects(tenantId: string, workspaceId?: string): Promise + createProject(data: CreateProjectRequest): Promise + // ... more methods with full type safety +} +``` + +--- + +## Monorepo Structure + +``` +metabuilder/ +├── redux/ +│ ├── slices/ (13 Redux slices) +│ ├── hooks/ (18 Tier 1 service-free hooks) +│ ├──

+### Before Phase 2 +``` +workflowui component + ↓ +useProject hook (service-dependent) + ↓ +projectService (direct HTTP) + ↓ +/api/projects endpoint +``` + +**Problems:** +- Hook tightly coupled to

(injected via React context) + ↓ +DefaultProjectServiceAdapter (HTTP) + OR +MockProjectServiceAdapter (testing) + OR +GraphQLProjectServiceAdapter (future) + ↓ +Backend service / In-memory storage +``` + +**Benefits:** +- Hook is framework-agnostic +- Can inject any adapter implementation +- Testing uses mocks, no server needed +- Easy to swap implementations + +--- + +## Usage Example + +### Setup (App Initialization) + +```typescript +import { ServiceProvider, DefaultAdapters } from '@metabuilder/service-adapters' +import App from './App' + +const services = { + projectService: new DefaultAdapters.ProjectServiceAdapter('/api'), + workspaceService: new DefaultAdapters.WorkspaceServiceAdapter('/api'), + workflowService: new DefaultAdapters.WorkflowServiceAdapter('/api'), + executionService: new DefaultAdapters.ExecutionServiceAdapter('/api'), + authService: new DefaultAdapters.AuthServiceAdapter('/api'), +} + +export default function Root() { + return ( + + + + ) +} +``` + +### Use Hooks (Component Level) + +```typescript +import { useProject } from '@metabuilder/hooks-data' +import { useLoginLogic } from '@metabuilder/hooks-auth' +import { useCanvasItems } from '@metabuilder/hooks-canvas' + +function Dashboard() { + // All hooks automatically get services from context + const { projects, loadProjects } = useProject() + const { canvasItems, deleteCanvasItem } = useCanvasItems() + const { handleLogin } = useLoginLogic() + + // Use hooks as normal, services are injected automatically + useEffect(() => { + loadProjects('workspace-123') + }, []) + + return ( + // Render component + ) +} +``` + +### Test (Test File) + +```typescript +import { render, screen } from '@testing-library/react' +import { ServiceProvider, MockAdapters } from '@metabuilder/service-adapters' +import Dashboard from './Dashboard' + +test('loads projects on mount', async () => { + const mockServices = { + projectService: new MockAdapters.ProjectServiceAdapter(), + // ... other mocks + } + + render( + + + + ) + + // No backend server, no API mocking needed + // MockAdapters provide in-memory data +}) +``` + +--- + +## Performance Considerations + +### In-Memory Mock Adapters +- Zero network latency in tests +- Fast test execution +- Instant feedback loop +- Great for CI/CD + +### HTTP Default Adapters +- Network latency (production-like) +- Real error handling +- API contract verification +- Works with any HTTP server + +### Future Implementations +- GraphQL: Flexible queries, reduced payload +- gRPC: Binary protocol, high performance +- WebSocket: Real-time data sync + +--- + +## Security & Best Practices + +### Authentication Handling +- Tokens stored in localStorage (configurable) +- Automatic token

Adapter Pattern is Powerful -The composition pattern (BaseAdapter → ValidationAdapter → ACLAdapter) allows adding features without modifying existing code. - -### 2. Multi-Tenancy is Mandatory -Every operation validates tenant ID. You can't accidentally expose cross-tenant data. - -### 3. Workflow Engine is Production-Ready -The DAG executor, node registry, and context systems are all in place. Just need validation and node executors. - -### 4. Validation is the Missing Piece -Current validation only checks field types. We need rule-based validation for: -- Node type registration -- Connection validity -- Multi-tenant safety -- Performance constraints - -### 5. Entity Operations are Consistent -All 19 entity types follow the same pattern. Adding a new entity takes minutes. - ---- - -## Next Steps - -### Immediate (1-2 hours) -1.

Full test coverage -3. Documentation -4. Performance benchmarking - -### Medium-term (1 week) -1. Implement DBAL node executors (dbal-read, dbal-write, dbal-delete, dbal-aggregate) -2. End-to-end workflow execution tests -3. Multi-tenant workflow tests - -### Long-term (Phase 3) -1. C++ implementation of DBAL -2. WebSocket bridge for distributed execution -3. Advanced caching strategies -4. Distributed transactions - ---- - -## References - -All code locations are absolute paths from repo root: - -### Core DBAL -- Main client: `/dbal/development/src/core/client/client.ts` -- Adapter factory: `/dbal/development/src/core/client/adapter-factory.ts` -- Base interface: `/dbal/development/src/adapters/adapter.ts` -- Entity types: `/dbal/development/src/core/foundation/types/types.generated.ts` - -### Workflow System -- Workflow types: `/dbal/development/src/workflow/types.ts` -- DAG executor: `/dbal/development/src/workflow/dag-executor.ts` -- Node registry: `/dbal/development/src/workflow/node-executor-registry.ts` -- Workflow operations: `/dbal/development/src/core/entities/operations/core/workflow-operations.ts` - -### Adapters -- Prisma: `/dbal/development/src/adapters/prisma/index.ts` -- Memory: `/dbal/development/src/adapters/memory/index.ts` -- ACL: `/dbal/development/src/adapters/acl-adapter/acl-adapter.ts` - -### Multi-Tenancy -- Tenant context: `/dbal/development/src/core/foundation/tenant/tenant-types.ts` -- Permission checks: `/dbal/development/src/core/foundation/tenant/permission-checks.ts` - -### Configuration -- Config types: `/dbal/development/src/runtime/config.ts` -- Error definitions: `/dbal/development/src/core/foundation/errors.ts` - ---- - -## Questions Answered - -**Q: How are queries isolated by tenant?** -A: Every operation resolves tenantId from config or entity data, then includes it in all filter clauses. If tenantId can't be resolved, operations throw an error. - -**Q: Can I add a new adapter?** -A: Yes, implement the DBALAdapter interface and register in adapter factory. No changes to entity operations needed. - -**Q: Can I add a new entity type?** -A: Yes, create type in types.generated.ts, add validation functions, create operations factory, and register in buildEntityOperations(). - -**Q: How does validation integrate?** -A: ValidationAdapter wraps base adapter and intercepts create/update operations for Workflow entity. Calls registry.validate() before delegating to base adapter. - -**Q: What's the performance impact of validation?** -A: ~1-5ms per workflow depending on rule complexity. Validation happens before database writes (catch errors early). - -**Q: Is ACL and Validation composable?** -A: Yes.

- Add `validateAgainstRegistry()` function - - Would require changes in multiple operation files - -3. **Node Executor Registry** (existing): - - Already has registration system (`NodeExecutorRegistry`) - - Can be queried to check node type support - - Global singleton via `getNodeExecutorRegistry()` - -### For DBAL Integration with Workflows: - -1. **DBAL Node Types** (already defined): - - `dbal-read`: Query DBAL entities - - `dbal-write`: Create/update DBAL entities - - `dbal-delete`: Delete DBAL entities - - `dbal-aggregate`: Group/count operations - -2. **Multi-Tenancy Support** (already in place): - - All workflows have `tenantId` field - - `WorkflowContext` includes tenant - - DBAL operations auto-filter by tenant - -3. **Error Handling** (already defined): - - `DBALError` with specific error codes - - Validation error with field details -

---- - -## Architecture Decision Records (ADRs) - -### ADR-1: Adapter Pattern for Storage -**Status**: ✅ Implemented -**Decision**: Use DBALAdapter interface with composable implementations -**Rationale**: Supports multiple backends, easy to add new adapters -**Location**: `core/client/adapter-factory.ts` - -### ADR-2: Multi-Tenant First -**Status**: ✅ Implemented -**Decision**: All queries must filter by tenantId; error if missing -**Rationale**: Prevents cross-tenant data leaks -**Location**: `core/entities/operations/*/operations.ts` - -### ADR-3: Entity Operations Pattern -**Status**: ✅ Implemented -**Decision**: Each entity has dedicated operations factory -**Rationale**: Single responsibility, consistent patterns, easy to extend -**Location**: `core/entities/operations/` - -### ADR-4: Validation Registry (Proposed) -**Status**: 🚀 Recommended Implementation -**Decision**: ValidationAdapter wraps base adapter, calls registry for Workflow entity -**Rationale**: Non-invasive, composable with other adapters, testable in isolation -**Location**: To be implemented in `adapters/validation-adapter/` - -### ADR-5: Error Codes -**Status**: ✅ Implemented -**Decision**: Standardized DBALError codes mapped to HTTP status codes -**Rationale**: Clear error semantics, easy client handling, audit logging -**Location**: `core/foundation/errors.ts` - ---- - -## Common Patterns - -### Pattern: Validate & Persist -```typescript -// Step 1: Validate input (in entity operations) -const errors = validateWorkflowCreate(data) -if (errors.length > 0) { - throw DBALError.validationError('Invalid workflow', errors.map(e => ({ field: 'workflow', error: e }))) -} - -// Step 2: Validate business rules (in ValidationAdapter) -const result = await registry.validate(data) -if (!result.valid) { - throw DBALError.validationError('Validation failed', ...) -} - -// Step 3: Persist (in base adapter) -return baseAdapter.create('Workflow', data) -``` - -### Pattern: Multi-Tenant Filtering -```typescript -// Always resolve tenant ID -const resolvedTenantId = resolveTenantId(configuredTenantId, data?.tenantId) -if (!resolvedTenantId) { - throw DBALError.validationError('Tenant ID is required', ...) -} - -// Always include in filters -const filter = { ...options.filter, tenantId: resolvedTenantId } -return adapter.list('Entity', { ...options, filter }) -``` - -### Pattern: Adapter Composition -```typescript -let adapter = createBaseAdapter(config) // Prisma, Memory, etc. -if (config.security?.enableWorkflowValidation) { - adapter = new ValidationAdapter(adapter) // Wrap with validation -} -if (config.auth?.user) { - adapter = new ACLAdapter(adapter, config.auth.user) // Wrap with ACL -} -return adapter -``` - ---- - -## Testing Patterns - -### Use MemoryAdapter for Unit Tests -```typescript -const adapter = new MemoryAdapter() -const client = new DBALClient({ mode: 'development', adapter: 'memory', tenantId: 'test' }) -// Use like normal DBAL client -``` - -### Test Validation Rules -```typescript -const registry = new WorkflowValidationRegistry() -registerDefaultRules(registry) -const result = await registry.validate(testWorkflow) -expect(result.valid).toBe(false) -expect(result.errors).toContain('expected error message') -``` - -### Test Multi-Tenant Isolation -```typescript -const client1 = new DBALClient({ ..., tenantId: 'tenant-1' }) -const client2 = new DBALClient({ ..., tenantId: 'tenant-2' }) -const wf1 = await client1.workflows.create(...) -const list2 = await client2.workflows.list() -expect(list2.items).not.toContain(wf1) // Should not see cross-tenant data -``` - ---- - -## Performance Guidelines - -- **Add validation sparingly**: ~1-5ms per operation -- **Use indexes on tenantId**: Essential for multi-tenant performance -- **Batch operations**: Use createMany/updateMany for bulk work -- **Connection pooling**: Configured in PrismaAdapter -- **Query timeouts**: Configurable in DBALConfig -

---- - -## Performance Considerations - -### Validation Overhead -- **Synchronous validation**: ~1-5ms per workflow (varies by rule complexity) -- **No database impact**: Validation happens before persistence -- **Rule execution**: Sequential, can be optimized with parallel execution if needed - -### Optimization Options - -1. **Lazy rule evaluation**: - ```typescript - // Only run expensive rules on first creation - const shouldRunExpensiveRules = !workflow.id // New workflow - ``` - -2. **Caching**: - ```typescript - // Cache validation result keyed by workflow ID + version - private validationCache = new Map() - ``` - -3. **Async rules** (future): - ```typescript - // For rules that need database queries - async validate(workflow: Workflow): Promise - ``` - ---- - -## Testing Strategy - -### Unit Tests -- ValidationAdapter delegates correctly -- Registry registers/retrieves rules -- Individual rule validation logic - -### Integration Tests -- End-to-end with MemoryAdapter -- Multi-tenant workflow validation -- ACL + Validation composition -- Error propagation through layers - -### Performance Tests -- Benchmark validation time vs workflow size -- Profile memory usage with large rule sets -

-#### 2. Recovery Strategies - -**Fallback** (`_applyFallback`) -- Attempts execution on fallback node type -- Graceful degradation -- Records attempt details -- Returns fallback output if successful - -**Skip** (`_applySkip`) -- Skips node execution without error -- Useful for optional operations -- Returns empty output -- Instant recovery (0 duration) - -**Retry** (`_applyRetry`) -- **Exponential backoff implementation** -- Configurable retry count (default: 3) -- Configurable backoff multiplier (default: 2x) -- Maximum delay cap (default: 30s) -- Jitter to prevent thundering herd -- Tracks all retry attempts -- Returns success on first successful attempt - -**Fail** (`_applyFail`) -- Propagates error without recovery -- Records error for analysis - -#### 3. `getMetrics(): ErrorMetrics` -- Returns copy of current metrics -- Safe for external consumption -- Includes all tracking data - -#### 4. `getErrorState(nodeId, timestamp): ErrorState | undefined` -- Retrieves specific error state by node ID and timestamp -- Useful for post-mortem analysis - -#### 5. `getErrorStatesForNode(nodeId): ErrorState[]` -- Gets all error states for a specific node -- Tracks error history per node - -#### 6. `getErrorStatistics(): {...}` -- Returns formatted statistics -- Grouped by type, node type, and strategy -- Includes counts for each category - -#### 7. `getRecoverySuccessRate(): number` -- Calculates recovery success percentage -- Returns 0 if no recovery attempts - -#### 8. `exportMetrics(): Record` -- Complete metrics export for monitoring/logging -- Includes summary, statistics, and recent errors -- Pre-formatted for external systems - -### Exponential Backoff Algorithm - -``` -delay = initialDelay * (multiplier ^ attemptNumber) -delay = min(delay + jitter, maxDelay) -``` - -**With Jitter**: -- Jitter = random(0 to 10% of delay) -- Prevents thundering herd problem -- More realistic retry distribution - -**Example with defaults**: -- Attempt 1: ~1s delay -- Attempt 2: ~2s delay (with jitter) -- Attempt 3: ~4s delay (with jitter) -- Capped at 30s max - -### Key Features - -**Four Recovery Strategies**: -- Fallback (delegate to alternative node) -- Skip (bypass gracefully) -- Retry (exponential backoff) -- Fail (propagate error) - -**Comprehensive Error Tracking**: -- Error state persistence (up to 500 states) -- Recovery history (up to 1,000 recovery attempts) -- Metrics aggregation by type, node, strategy -- Attempt-level audit trail - -**Metrics & Monitoring**: -- Success/failure rates -- Average recovery time -- Error type distribution -- Recovery attempt counts -- Last error timestamp - -**Memory Management**: -- Bounded error state storage (MAX_ERROR_STATES = 500) -- Bounded recovery time history (MAX_RECOVERY_HISTORY = 1,000) -- Old states auto-trimmed when exceeding limits -- Efficient cleanup on reset - -**Multi-Tenant Support**: -- Tenant ID tracked in error context -- User ID and execution ID captured -- Context preserved for audit logging - ---- - -## Integration Points - -### With PluginValidator - -The error recovery manager works in conjunction with the validator: - -```typescript -// 1.

Execute with recovery -const result = await errorRecovery.handleError( - nodeType, - node.id, - error, - recoveryStrategy, - ... -) -``` - -### With WorkflowNode - -Both modules work directly with `WorkflowNode`: -- Validates node structure and parameters -- Executes node with error recovery -- Tracks node execution metrics - -### With WorkflowContext - -Multi-tenant context is preserved: -- Tenant ID for isolation -- User ID for audit logging -- Execution ID for tracing - ---- - -## Code Quality - -### TypeScript Features -- Full type safety with interfaces -- Enum for error classification -- Generic constraints where needed -- No use of `any` except for data schemas - -### Documentation -- Comprehensive JSDoc on all public methods -- Parameter descriptions -- Return type documentation -- Usage examples in comments - -### Error Handling -- Graceful error mapping -- Non-recoverable error classification -- Suggested remediation actions -- Detailed error context preservation -

This is n8n's standard format. - -**Q: What if a node type (e.g., `dbal.entity_list`) isn't registered?** -A: Check the plugin registry. If missing: -1. Implement the plugin (would be a separate task) -2. Register it in the executor -3. Or use a different available node type - -**Q: How is multi-tenant isolation enforced?** -A: Every query filters: `filter: { tenantId: "$request.tenantId" }`. The database only returns data for that tenant. - -**Q: What happens if a user isn't Supergod?** -A: Returns 403 Forbidden error. No access to schema editor operations. - -**Q: Do I need to handle the codegen workflow in save-schema?** -A: Yes - the `workflow.execute` node triggers the Prisma schema generation workflow automatically. This is critical for making the new entity usable. - ---- - -## Support & Resources - -### For Implementation Questions -- Reference: `UI_SCHEMA_EDITOR_WORKFLOW_UPDATE_PLAN.md` (detailed specs) -- Checklist: `UI_SCHEMA_EDITOR_WORKFLOW_CHECKLIST.md` (step-by-step) -- Examples: Both documents have complete JSON examples - -### For N8N Format Questions -- Check connection format section (critical!) -- Review existing workflows in `/packagerepo/backend/workflows/` -- Study examples in the plan document - -### For Multi-Tenant Questions -- Read `/docs/MULTI_TENANT_AUDIT.md` -- All DBAL queries must filter by tenantId -- Pattern: `filter: { tenantId: "$request.tenantId" }` - -### For Security Questions -- Always verify role before sensitive operations -- Return proper HTTP status codes (403, 404) -- Never expose sensitive data in error messages - ---- - -## Document Statistics -

Add Missing ID Field -- **Automatically generates** workflow IDs from filenames -- **Pattern validation**: `^[a-zA-Z_][a-zA-Z0-9_]*$` -- **Example**: `auth_login.json` → `workflow_auth_login` -- **Idempotent**: Doesn't re-generate if already present - -### 2. Add Version Field -- **Sets version to**: `3.0.0` (n8n v1.0+ standard) -- **Enables**: Version tracking and migration support -- **Optional**: Can be manually overridden - -### 3. Add TenantId Field -- **Sets tenantId to**: `${TENANT_ID}` (variable reference) -- **Purpose**: Multi-tenant isolation support -- **Template-compatible**: Works with environment variable expansion - -### 4. Add Active Field -- **Sets active to**: `true` (enables workflow by default) -- **Control**: Can be set to false to disable without deletion -- **Optional**: Workflows work without it (defaults to true) - -### 5. Detect and Fix Nested Parameters -- **Detects**: Node-level fields in parameters (e.g., `type`, `name` in parameters) -- **Fixes**: Moves fields to correct node level -- **Validation**: Ensures parameters only contain configuration -- **Errors**: Reports structure violations - -### 6. Validate Against Schema -- **ID validation**: Regex pattern matching -- **Name validation**: Length constraints (1-255 chars) -- **Type validation**: Format checking -- **TypeVersion validation**: Integer >= 1 -- **Position validation**: [x, y] number arrays -- **Connection validation**: Target nodes exist -

Load plugin manifests from database -// 2. Dynamically import and register -// 3.

Type-Level**: -```typescript -export interface WorkflowDefinition { - tenantId: string; // REQUIRED - // ... -} - -export interface WorkflowContext { - tenantId: string; // REQUIRED - userId: string; - user: { id, email, level }; - // ... -} -``` - -**2. Validation-Level**: -```typescript -// In WorkflowValidator.validateMultiTenantSafety(): -if (!workflow.tenantId) { - errors.push({ - code: 'MISSING_TENANT_ID', - message: 'Workflow must have a tenantId for multi-tenant safety' - }); -} -``` - -**3. Execution-Level** (DBAL Executor Example): -```typescript -// In DBALReadExecutor.execute(): -const resolvedFilter = interpolateTemplate(filter, { context, state, ... }); - -// Enforce tenant filtering -if (context.tenantId && !resolvedFilter.tenantId) { - resolvedFilter.tenantId = context.tenantId; // AUTO-INJECT -} -``` - -**4. Template Engine-Level**: -```typescript -// Context variables include tenant info: -interpolateTemplate(params, { - context: { tenantId, userId, ... }, - state: executionState, - ... -}) -``` - -### Multi-Tenant Safety Verification Checklist - -- ✓ `WorkflowDefinition.tenantId` enforced at type level -- ✓ `WorkflowContext.tenantId` required for execution -- ✓ `WorkflowValidator` checks for missing tenantId -- ✓ `WorkflowValidator` warns about global-scope variables -- ✓ `DBAL plugins` auto-inject tenantId into filters -- ✓ Template engine scopes variables to execution context -- ⚠ **Gap**: No audit logging of cross-tenant access attempts -- ⚠ **Gap**: No runtime enforcement in generic node executors - -### Recommended Multi-Tenant Improvements - -```typescript -// 1. Add audit trail to execution -export interface WorkflowContext { - tenantId: string; - auditTrail?: { - timestamp: Date; - action: string; - sourceNode: string; - accessedEntity?: string; - }[]; -} - -// 2. Add tenant access validator -class TenantAccessValidator { - validateNodeAccess(node: WorkflowNode, context: WorkflowContext): ValidationResult { - // Check if node operations respect tenant boundaries - } -} - -// 3.

---- - -## Troubleshooting Guide - -| Problem | Cause | Solution | -|---------|-------|----------| -| "No executor registered for node type X" | Node type not registered | Call `initializeWorkflowEngine()` or register manually | -| Multi-tenant isolation broken | tenantId not in context | Ensure `context.tenantId` is set before execution | -| Template interpolation returns literal | Syntax error in template | Check `{{ }}` syntax, use `$context.`, `$json.`, etc. | -| Workflow hangs (infinite loop) | Circular connections | Check workflow connections for cycles | -| Retry not triggering | Error not retryable | Check `retryableErrors` list in retry policy | -| Validation fails but should pass | Nested parameters too deep | Ensure parameters nesting ≤ 2 levels | - ---- -
