Phase 03 Plan 01: Module SDK + Registry Service Summary

Module SDK package with versioned interface contract and database-driven module registry with per-tenant activation/deactivation via REST API and ModuleGuard for access control.

What Was Built

Task 1: Module SDK Package + Prisma Schema (8c24c1e)

@tessera/module-sdk package (packages/module-sdk/):

• TesseraModule interface: full module definition with id, name, version, slug, category, i18n descriptions, icon, routes, lazy-loaded components
• ModuleRoute interface: HTTP method, path, handler for module API routes
• ModuleManifest type: backend-only metadata (omits component/cardComponent)
• ModuleCategory type: string literal union for module grouping
• ComponentType: framework-agnostic component type for lazy-loaded UIs

Prisma schema extensions:

• Module model: id (UUID), slug (unique), name, version, category, description (JSON), icon, isSystem flag, timestamps
• TenantModuleActivation model: tenant-module join with isActive soft-delete, unique constraint on [tenantId, moduleId], index on tenantId
• Migration 20260619103242_add_module_registry applied successfully

Task 2: ModuleRegistry NestJS Module (fa15d35)

ModuleRegistryService — full CRUD + tenant activation:

• findAll(): list all registered modules
• findBySlug(slug): lookup by slug
• findActiveForTenant(tenantId): active modules for a tenant
• activateForTenant(tenantId, moduleId): upsert activation record
• deactivateForTenant(tenantId, moduleId): soft-delete (isActive=false)
• isModuleActive(tenantId, moduleSlug): boolean check for guard
• seedModule(manifest): upsert module by slug for startup seeding

ModuleRegistryController — REST endpoints:

• GET /modules — list all modules (any authenticated user)
• GET /modules/active — active modules for current tenant
• POST /modules/:moduleId/activate — ADMIN/SUPER_ADMIN only
• POST /modules/:moduleId/deactivate — ADMIN/SUPER_ADMIN only

ModuleGuard + @UseModule() decorator:

• CanActivate guard checking tenant module activation via slug
• Composed decorator: @UseModule('domaincheck') applies metadata + guard
• TenantId sourced from JWT/middleware (not user input) per T-03-04

ActivateModuleDto with @IsUUID() validation per T-03-02.

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] React.ComponentType reference in SDK types

• Found during: Task 1
• Issue: types.ts referenced React.ComponentType but the SDK package has no React dependency, causing TypeScript errors
• Fix: Defined a framework-agnostic ComponentType within the SDK instead of depending on React types
• Files modified: packages/module-sdk/src/types.ts

2. [Rule 1 - Bug] DTO definite assignment in strict mode

• Found during: Task 2
• Issue: ActivateModuleDto.moduleId property lacked definite assignment assertion, causing TS2564 with strict mode
• Fix: Added ! definite assignment assertion (moduleId!: string) consistent with class-validator pattern
• Files modified: apps/api/src/module-registry/dto/activate-module.dto.ts

Threat Mitigations Applied

Threat ID	Mitigation	Implementation
T-03-01	@Roles(ADMIN, SUPER_ADMIN) on activate/deactivate	module-registry.controller.ts
T-03-02	@IsUUID validator + Prisma parameterized queries	activate-module.dto.ts, module-registry.service.ts
T-03-03	Module catalog accessible to all authenticated users	GET /modules has no role restriction
T-03-04	tenantId from request (JWT/middleware), not user input	module.guard.ts uses req.tenantId

Verification Results

• API build: PASS
• Prisma migration status: up to date (3 migrations)
• SDK type-check: PASS
• Required exports present: TesseraModule, ModuleRoute, ModuleManifest, ModuleCategory
• No stubs or placeholders found

Self-Check: PASSED
