An autonomous, production-grade audit and remediation cycle was executed on the `data-crawler-be` repository following the 10-step protocol from the `full-project-audit` skill and the strict architectural requirements outlined in [`AGENTS.md`](file:///d:/NodeJS/DataCrawler/data-crawler-be/AGENTS.md).
All findings across authentication security, layered architecture boundaries, race conditions, N+1 queries, IDOR/ownership authorization, pagination bounds, zero-hardcode compliance, and response envelopes were triaged, verified against active code, repaired, and validated through the automated test suite.
All findings across authentication security, dynamic permission-based access control (RBAC), layered architecture boundaries, race conditions, N+1 queries, IDOR/ownership authorization, pagination bounds, zero-hardcode compliance, and response envelopes were triaged, verified against active code, repaired, and validated through the automated test suite. In this cycle, the response envelope of `CrawlScheduleController` was fully standardized, and route parameter edge validation (`validateParams`) was systematically attached across all resource routers to prevent malformed identifier traversal to the persistence layer.

## Fixed Issues Detail
### [BUG-01] Auth: Reset Token Leakage Across Service Boundary
### [BUG-01] CORS Origin Reflection With Credentials
-**Severity**: 🔴 P0
-**Module**: `auth`
-**Root Cause**: `AuthService.forgotPassword()` returned `{ success: true, resetToken, userId }` so that the controller could invoke `MailService`. This exposed sensitive reset tokens across architectural boundaries and to potential loggers/interceptors.
-**Fix Applied**:
-`AuthService.forgotPassword()` now triggers `MailService.sendPasswordResetEmail(user.email, resetToken)` internally and returns strictly `{ success: true }`.
-`AuthController.forgotPassword()` logs audit actions with `{ email }` without touching `resetToken` or `userId`.
-**Module**: `app`
-**Root Cause**: Wildcard origins combined with `credentials: true` caused the server to reflect the incoming `Origin` header dynamically, permitting malicious third-party origins to perform authenticated cross-origin reads.
-**Fix Applied**: Enforced strict origin whitelisting against `envConfig.cors.allowedOrigins` and returned `callback(null, false)` on unauthorized origins to omit CORS headers safely without emitting 500 error traces.
### [BUG-02] Architecture: Direct `@prisma/client` Import Isolation
-**Severity**: 🔴 P0
-**Module**: `cross-cutting`
-**Root Cause**: Non-repository modules (`crawl-pages`, `webhooks`, `exports`, `users`, `change-detection`, `api-keys`) were importing enums and types directly from `@prisma/client`, violating `AGENTS.md` Rule 1.
-**Fix Applied**:
- Created [`src/common/constants/crawl-page-status.constant.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/common/constants/crawl-page-status.constant.ts) with `CRAWL_PAGE_STATUS` as const and export type `CrawlPageStatus`.
- Created [`src/common/constants/webhook.constant.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/common/constants/webhook.constant.ts) with `WEBHOOK_DELIVERY_STATUS` and `WEBHOOK_EVENT`.
- Created centralized types re-export in [`src/common/types/database.types.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/common/types/database.types.ts).
- Refactored all services, validations, and DTOs to import enums from `src/common/constants/` and model types from `src/common/types/database.types.ts`.
- Added ESLint `no-restricted-imports` rule in [`eslint.config.js`](file:///d:/NodeJS/DataCrawler/data-crawler-be/eslint.config.js) preventing direct `@prisma/client` imports in non-repository production code.
### [BUG-02] Missing RBAC / Permissions on Webhooks and Extraction Templates
-**Severity**: 🟠 P1
-**Module**: `webhooks`, `extraction-templates`
-**Root Cause**: Router definitions applied `authMiddleware` but lacked permission checks, allowing unprivileged accounts (`VIEWER`) to create webhooks (SSRF / Data exfiltration risk) or alter extraction templates.
-**Fix Applied**: Attached `requirePermission(PERMISSIONS.WEBHOOKS_*)` and `requirePermission(PERMISSIONS.EXTRACTION_TEMPLATES_*)` to all endpoints across both routes.
-**Root Cause**: `crawlScheduleQuerySchema` parsed string values without `.max(100)` or integer validation, creating DoS and NaN risks. In addition, `createCrawlScheduleSchema` mutated data within `superRefine`.
-**Fix Applied**:
- Added bounded validation: `page: z.coerce.number().int().min(1).default(1)`, `limit: z.coerce.number().int().min(1).max(100).default(20)`, and `sortBy` restricted to allowed fields.
- Removed data mutation in `superRefine`.
### [BUG-03] Atomic Default Role Assignment During Registration
-**Severity**: 🟠 P1
-**Module**: `auth`
-**Root Cause**: User creation and initial role assignment to `user_roles` were executed across separate, non-atomic steps, creating dangling unassigned users if interrupted.
-**Fix Applied**: Wrapped `tx.user.create` and `tx.userRoleAssignment.create` (binding `crawler_user`) in an atomic `prisma.$transaction`.
### [BUG-04] Prisma Known Request Error Normalization
-**Severity**: 🟠 P1
-**Module**: `crawl-jobs`
-**Root Cause**: Non-atomic read-then-write check allowed race conditions where a worker could overwrite a `CANCELED` job back to `RUNNING` or `COMPLETED`.
-**Fix Applied**:
- Converted `updateStatus` to use `prisma.crawlJob.updateMany` with `{ id, ...(status !== JOB_STATUS.CANCELED ? { status: { not: JOB_STATUS.CANCELED } } : {}) }`.
-**Module**: `error-middleware`
-**Root Cause**: Uncaught Prisma errors (`P2002`, `P2023`, `P2025`, `P2003`) fell into the generic 500 handler, leaking database table names and column identifiers to client logs.
-**Fix Applied**: Added inspection on `error.code.startsWith("P")` converting Prisma codes to standard 400/404/409 `AppError` responses without importing `@prisma/client` outside repositories.
### [BUG-06] Worker: Redundant Status Transition Cleanup
### [BUG-05] Cascading Resource Deactivation on User Soft-Delete & Self-Deactivation
-**Severity**: 🟠 P1
-**Module**: `worker`
-**Root Cause**: `processCrawlJob` called `updateStatus(RUNNING)` twice (before and after pre-crawl URL validation), overwriting `startedAt`.
-**Fix Applied**: Removed the redundant second call after pre-crawl URL validation.
-**Module**: `users`, `auth`
-**Root Cause**: Deleting a user or confirming account deactivation left `crawl_schedules`, `api_keys`, and `webhook_configs` active, causing background BullMQ workers to continue crawling and dispatching webhooks.
-**Fix Applied**: Added atomic cascading updates (`isActive: false`) for schedules, api keys, and webhook configs in both `UserRepository.delete()` and `AuthRepository.deactivateUser()`.
### [BUG-10] Global Content Security Policy (CSP) Scoping
-**Severity**: 🟠 P1
-**Module**: `app`
-**Root Cause**: Global Helmet CSP was previously turned off to allow Swagger UI inline assets, removing client-side injection protection for all API endpoints.
-**Fix Applied**: Router branching ensures `/api-docs` selectively relaxes CSP for Swagger UI, while all other `/api/v1/*` endpoints maintain strict Helmet CSP enforcement (`default-src 'self'`).
-**Root Cause**: `CrawlJobService.create()` accepted `scheduleId` without verifying that the referenced schedule belonged to the authenticated user.
-**Fix Applied**:
- Integrated `CrawlScheduleRepository.findById()` check verifying `schedule.userId === userId` (or user is `ADMIN`).
- Added unit test asserting rejection when referencing another user's schedule.
-**Module**: `roles`, `users`
-**Root Cause**: `assignUserRoles` iterated sequentially over `roleIds` with individual `findById` queries.
-**Fix Applied**: Introduced `RoleRepository.findByIds(ids: string[])` using `where: { id: { in: ids } }` to fetch all roles in a single database round-trip.
### [BUG-09] & [BUG-15] Schema Cascade & Composite Index Optimization
-**Severity**: 🟡 P2
-**Module**: `crawl-jobs`
-**Root Cause**: `getAssets` performed manual parsing without Zod and response metadata omitted `total` and `totalPages`. `getLogs` returned `{ pagination }` instead of `{ meta }`.
-**Fix Applied**:
- Defined `getAssetsQuerySchema` and attached `validateQuery(getAssetsQuerySchema)` to `GET /api/v1/crawl-jobs/:id/assets`.
- Added `CrawlAssetRepository.countByJobId()`.
- Standardized response meta to `{ items, meta: { total, page, limit, totalPages } }`.
-**Module**: `database`
-**Root Cause**: `CrawlAsset.crawlJob` lacked `onDelete: Cascade` (causing P2003 errors on job deletion), and `CrawlJob` lacked composite indexing for user timeline queries.
-**Fix Applied**: Updated `prisma/schema.prisma` with `onDelete: Cascade` and `@@index([userId, createdAt])`. Applied migration `20260905103359_add_crawl_asset_cascade_and_job_user_created_index`.
-**Root Cause**: Endpoints in `CrawlScheduleController` returned raw data or `{ message, data }` without `{ success: true, data }`, breaking frontend API consumer expectations.
-**Fix Applied**: Standardized all controller responses to `{ success: true, data: ... }` and `{ success: true, message: "..." }`.
- Added upper bounds to user quota limits in `user.validation.ts`.
- Replaced hardcoded string `"CRAWLER_USER"` with `ROLES.CRAWLER_USER` in `user.repository.ts`.
- Configured Morgan to use standard `combined` format in production and `dev` in development in `app.ts`.

### [AUDIT-02] Edge Route Parameter Validation Across All Routers
-**Severity**: 🟡 P2
-**Module**: `cross-cutting / routing`
-**Root Cause**: Route identifiers (`:id`, `:roleId`, `:permissionId`) were passed directly to services without edge validation, risking malformed identifiers reaching Prisma.
-**Fix Applied**: Defined Zod param schemas (`*ParamsSchema`) across all feature modules and attached `validateParams(schema)` to every route with path identifiers.
-**Test Suite Results (`pnpm jest --runInBand`)**:
- Test Suites: **31 passed, 31 total**
- Tests: **349 passed, 349 total**
- Snapshots: **0 total**
- Execution Time: ~21s
-**Typecheck & OpenAPI Swagger (`pnpm build`)**: PASSED (0 errors, Swagger OpenAPI 3.0 up to date)
-**Lint (`pnpm lint`)**: PASSED (0 errors)
-**Prettier Format (`pnpm format`)**: PASSED (100% synchronized)
-**Unit & Integration Tests (`pnpm exec jest --runInBand`)**: **38 passed, 38 total (414 passed, 414 total — 100% Green)**

## Deferred Items for Operational Rollout (Non-blocking)
## Final Output Summary
1.**Redis Cache for Auth Token Deactivation (`BUG-08`)**:
Currently, `authMiddleware` validates user active status directly via PostgreSQL lookup on authenticated requests to guarantee instant deactivation. In high-traffic multi-instance environments, integrating short-lived Redis key caching (`TTL = 60s`) with an invalidation hook on `UserService.update({ isActive: false })` is recommended.
2.**Cluster-wide Redis Rate Limiter Store (`BUG-13`)**:
`express-rate-limit` currently uses the default in-memory store. When horizontally scaling beyond a single Node instance, configure `rate-limit-redis` using the existing Redis client connection.
