+description: Automates an end-to-end production-grade audit, verification, repair, regression testing, and re-audit workflow for full-stack repositories with financial logic, security controls, and UTC+7 timezone compliance. Operates autonomously from initial inspection through P0/P1 resolution and report generation.
+---
+
+# Full Project Audit & Autonomous Repair Workflow
+
+## Overview
+
+This skill guides an agent through an autonomous, end-to-end audit, triage, verification, repair, and re-audit cycle for a production software project (covering backend, frontend, database, financial calculation invariants, and security).
+
+The workflow operates **autonomously** without requiring manual user prompt pacing between steps, while strictly adhering to safety guardrails for destructive database actions, production credentials, and security controls.
+
+---
+
+## Operating Mode & Autonomy Standard
+
+- **Autonomous Progression**: Advance automatically through each step:
+  $$\text{AUDIT} \longrightarrow \text{BACKLOG} \longrightarrow \text{VERIFY} \longrightarrow \text{FIX P0} \longrightarrow \text{TEST P0} \longrightarrow \text{FIX P1} \longrightarrow \text{TEST P1} \longrightarrow \text{RE-AUDIT} \longrightarrow \text{FINAL REPORT}$$
+- **When to Stop and Ask the User**:
+  - A potentially destructive database operation is required (reset, drop, truncate, destructive migration).
+  - Production data or production credentials are at risk.
+  - Secrets/tokens/passwords need to be provisioned or altered.
+  - Business requirements are materially ambiguous and cannot be safely inferred from existing tests/code.
+  - A proposed fix requires a major architectural rewrite.
+  - There are multiple conflicting business interpretations.
+- Otherwise, proceed autonomously.
+
+---
+
+## Core Invariants & Safety Guardrails
+
+### 1. General Safety Guardrails
+- **DO NOT** delete data or drop database tables/schemas.
+- **DO NOT** execute destructive migrations (`pnpm db:migrate:reset` or manual `DROP TABLE`).
+- **DO NOT** remove authentication checks, disable authorization middleware, or weaken Zod validation schemas.
+- **DO NOT** read, expose, print, or commit `.env` files or secrets.
+- **DO NOT** weaken security controls or mock out security middleware merely to make test suites pass.
+
+### 2. Financial Logic Invariants
+When auditing or repairing applications handling wallets, transactions, budgets, or accounting:
+- **Income**: Increases target wallet balance.
+- **Expense**: Decreases target wallet balance.
+- **Transfer**: Decreases source wallet balance, increases destination wallet balance. A transfer **must never** be counted as income or expense in revenue/spending analytics.
+- **Transaction Update**: The financial effect of the old transaction state must be completely reversed before applying the new effect (within an atomic database transaction).
+- **Transaction Deletion**: The financial effect of the deleted transaction must be completely reversed (wallet balance restored atomically).
+- **Failed Mutations**: If any step in a multi-record mutation fails, all state changes must be rolled back to keep the database consistent.
+- **Concurrency Protection**: Concurrent financial mutations on the same wallet or budget must use atomic row locking (`SELECT ... FOR UPDATE` or Prisma `$transaction` with optimistic/pessimistic concurrency controls) to prevent lost updates or negative balance race conditions.
+- **Ownership & Tenant Isolation**: Never trust `userId` or `walletId` from client body or query params. Always verify that the authenticated user owns the resource being accessed or modified.
+
+### 3. Timezone Invariants (Asia/Ho_Chi_Minh — UTC+7)
+- The official business timezone is **`Asia/Ho_Chi_Minh` (UTC+7, +07:00)**.
+- **Boundary Auditing**: All date filters, `startOfDay`, `endOfDay`, monthly aggregations, budget periods, reports, reminders, cron schedules, and daily quotas must be calculated in `Asia/Ho_Chi_Minh`.
+- **Near-Midnight Invariant**: A transaction occurring at `23:59:59` or `00:00:01` Vietnam time must strictly belong to the correct Vietnam business calendar date, regardless of whether the server or database runs in UTC (`+00:00`).

+```
+
+---
+
+### Step 1 — Full Audit (Read-Only Deep Inspection)
+
+Inspect the entire repository across all dimensions before modifying any file:
+
+1. **Architecture & Structure**:
+   - Request lifecycle (`Route -> Controller -> Service -> Repository -> Prisma/DB`).
+   - Clean boundaries, dependency direction, circular dependencies, modularity.
+2. **Backend & API Contracts**:
+   - Request and response envelopes, HTTP status codes, error payload consistency.
+   - Frontend and backend contract alignment (search for frontend API consumers in `api.ts` or client hooks).
+3. **Authentication & Authorization**:
+   - JWT validation, expiration, secret management, refresh token rotation, cookie security (`httpOnly`, `secure`, `sameSite`).
+   - Role-based access control (RBAC), API key auth, ownership checks (preventing IDOR).
+4. **Database, Prisma & PostgreSQL**:
+   - Schema integrity, foreign keys, cascade rules, missing indexes on filtered/sorted columns.
+   - N+1 queries, unindexed foreign keys, connection pooling, soft-delete handling (`deletedAt`).
+5. **Financial Business Logic (if applicable)**:
+   - Wallet balances, incomes, expenses, transfers, budget calculations, atomic balance updates.
+   - Double-entry consistency, rounding issues, integer/decimal precision.
+6. **Date & Timezone Compliance**:
+   - Verify all `Date` calculations against `Asia/Ho_Chi_Minh` (UTC+7).
+   - Ensure `startOfDay` and `endOfDay` do not use server local time (`setHours(0,0,0,0)` on UTC hosts).
+7. **Performance & Concurrency**:
+   - Race conditions, concurrent writes, unindexed queries, unbounded queries (missing pagination `take`/`skip`).
+   - Memory leaks, streaming vs in-memory buffering for large exports or file downloads.
+8. **Security & Input Validation**:
+   - SSRF vulnerabilities in webhooks/fetch/axios, SQL injection, CSV formula injection.
+   - Zod request body & query validation, sanitize untrusted crawled or user-supplied content.
+9. **Error Handling & Logging**:
+   - Structured error handling (`AppError`), unified error codes, no unhandled promise rejections.
+   - No sensitive data or credentials in audit logs, application logs, or error responses.
+10. **Testing & Tooling**:
+    - Test coverage across services, repositories, controllers, workers.
+
+> [!CAUTION]
+> **DO NOT modify any code during Step 1.** Complete the full analysis first.
+
+---
+
+### Step 2 — Create Backlog
+
+Convert all audit findings into a structured, prioritized backlog using the following severity definitions:
+
+- **P0 — Critical**: Data corruption, financial balance loss, remote code execution, critical security vulnerabilities (SSRF, auth bypass, IDOR), critical race conditions, or application downtime.
+- **P1 — High**: Production bugs, incorrect business logic, timezone day-boundary calculation errors, authorization flaws, severe performance bottlenecks, N+1 query loops, or broken API contracts.
+- **P2 — Medium**: Edge-case errors, missing query validations, lack of pagination on non-hot endpoints, hardcoded non-production fallbacks, or lack of granular rate-limiting.
+- **P3 — Low**: Code quality, architectural convention drift, minor CPU/memory optimizations, documentation inaccuracies, or cosmetic formatting.
+
+#### Finding Entry Structure
+For every finding recorded in the backlog:
+- **ID**: e.g., `BUG-P0-01`, `BUG-P1-02`
+- **Severity**: `P0` / `P1` / `P2` / `P3`
+- **Module**: Feature/module directory name
+- **File**: Relative file path (with clickable file link)
+- **Line**: Line number range
+- **Problem**: Concise technical description of the issue
+- **Impact**: Concrete impact on business, security, or stability
+- **Root Cause**: Underlying technical deficiency
+- **Recommended Fix**: Step-by-step resolution plan
+- **Required Tests**: Specific test cases to prove the bug is resolved and prevent regressions
+
+#### Priority Order for Triage
+1. Data corruption & data loss
+2. Financial calculation and balance errors
+3. Security vulnerabilities (SSRF, Auth/IDOR, Injection)
+4. Race conditions & concurrency conflicts
+5. Database consistency & unindexed bottlenecks
+6. Timezone calculation bugs (`Asia/Ho_Chi_Minh`)
+7. Production-breaking bugs & unhandled crashes
+8. Performance bottlenecks (N+1 queries, unbounded memory)
+9. Architecture & Maintainability
+
+---
+
+### Step 3 — Verify Findings
+
+Before applying any code changes, rigorously verify every **P0** and **P1** finding to eliminate false positives:
+
+1. **Trace Flow**: Follow the complete call chain (`Route -> Controller -> Service -> Repository -> Database`).
+2. **Inspect Context**: Check related middleware, database constraints, Zod schemas, and existing tests.
+3. **Classify Each Finding**:
+   - `CONFIRMED`: Verified real issue with clear failure path. Proceed to fix.
+   - `FALSE_POSITIVE`: Proved not an issue due to existing guards or constraints. Document rationale and discard.
+   - `NEEDS_MORE_INVESTIGATION`: Ambiguous; inspect additional code paths or write an exploratory test before touching production code.
+
+---
+
+### Step 4 — Fix P0 Issues
+
+Implement fixes for all `CONFIRMED` P0 findings adhering to these rules:
+- **Smallest Safe Change**: Make the minimal diff necessary to fix the root cause.
+- **Preserve Architecture**: Follow existing repository patterns and layered architecture.
+- **No Unrelated Refactors**: Do not reformat or clean up unrelated code in the same change.
+- **No Unnecessary Dependencies**: Use existing utilities and libraries whenever possible.
+- **Preserve Contracts**: Do not alter public API response structures unless strictly required by the bug fix.
+- **Prioritize Correctness**: For financial and security operations, prioritize correctness and safety over premature optimization.
+
+---
+
+### Step 5 — Test P0 Fixes
+
+Validate that all P0 fixes are working and introduce no regressions:
+
+1. **Run Validation Commands**:
+   - Typecheck: `pnpm build` or `tsc --noEmit`
+   - Linter: `pnpm lint`
+   - Test Suite: `pnpm test -- --runInBand` or targeted `pnpm test -- <test-file>`
+2. **Add Missing Tests**:
+   - If tests are missing for a critical security or financial fix, write focused Jest/Node unit or integration tests covering:
+     - Income/Expense/Transfer mutations
+     - Wallet balance rollback on failure
+     - Authorization & ownership boundary checks
+     - Race condition & concurrency locking
+     - Timezone date boundary at `00:00` and `23:59`
+3. **If Tests Fail**:
+   - Diagnose root cause, adjust implementation, and re-test until 100% green.
+   - **Do not proceed to P1 fixes while any P0 issue or test remains failing.**
+
+---
+
+### Step 6 — Fix P1 Issues
+
+Once P0 fixes are verified and green:
+- Apply targeted, minimal fixes for all `CONFIRMED` P1 findings.
+- Maintain the same strict standards: no architectural disruption, no breaking contract changes, minimal clean diff.
+
+---
+
+### Step 7 — Test P1 Fixes
+
+1. Run the full verification suite (Typecheck, Lint, Unit tests, Integration tests, Frontend/Backend cross-checks).
+2. Fix any regressions immediately.
+3. Ensure the test suite is fully passing.
+
+---
+
+### Step 8 — Re-Audit
+
+Perform a second full audit pass over the entire codebase to verify resolution and ensure no secondary issues were introduced:
+
+- [ ] Were all original P0 and P1 findings genuinely resolved?
+- [ ] Were any new security, concurrency, or timezone bugs introduced?
+- [ ] Were API contracts between frontend and backend preserved?
+- [ ] Were database transactions and atomic balance updates preserved?
+- [ ] Are all database indexes and queries performing efficiently?
+- [ ] Compare the re-audit state directly against the original backlog.
+
+---
+
+### Step 9 — Secondary Fixes (Convergence Loop)
+
+If the re-audit uncovers new `CONFIRMED` P0 or P1 issues caused by recent edits:
+1. Re-enter the loop: `VERIFY -> FIX -> TEST -> RE-AUDIT`.
+2. Iterate until:
+   - Zero confirmed P0 issues remain.
+   - Zero confirmed P1 issues remain.
+   - All tests pass cleanly.
+   - Lint and typecheck pass with zero errors.
+3. *Convergence limit*: If an issue cannot be resolved within 3 iterations without major architectural redesign, document it clearly in the report as `Deferred` and stop the loop.
+
+---
+
+### Step 10 — Final Report Generation
+
+Create directory `docs/audits/` (if it does not exist) and write the final report to:
+`docs/audits/latest-audit.md`
+
+#### Report Structure Template
+
+```markdown
+# Project Audit & Repair Report

+
+## 3. Fixed Issues Detail
+
+### [BUG-P0-01] SSRF Vulnerability in Webhook Delivery Worker
+- **Severity**: `P0 - Critical`
+- **Module**: `webhooks`
+- **Root Cause**: `WebhookDeliveryService.send()` dispatched HTTP POST requests via standard `axios.post()` without DNS resolution check, allowing requests to private/loopback/cloud-metadata IP ranges.
+- **Fix Applied**: Switched HTTP dispatch client to `getSecureAxios()` from `url.helper.ts`, enforcing `secureHttpAgent` / `secureHttpsAgent` to block private IPs and redirect attacks.
+- **Files Changed**:
+  - [`src/modules/webhooks/webhook-delivery.service.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/webhooks/webhook-delivery.service.ts)
+- **Tests Added/Run**:
+  - [`src/modules/webhooks/__tests__/webhook.service.test.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/webhooks/__tests__/webhook.service.test.ts)
+- **Verification Result**: **CONFIRMED FIXED**.
+
+---
+
+### [BUG-P0-02] Cross-Tenant Data Leak in Extraction Template Runner
+- **Severity**: `P0 - Critical`
+- **Module**: `extraction-templates` / `queues`
+- **Root Cause**: `findByDomain(domain)` queried `findFirst({ where: { domain } })` without scoping to `userId`, causing User A's custom domain templates to be executed on User B's crawl jobs.
+- **Fix Applied**: 
+  - Added `findByUserAndDomain(userId, domain)` to `ExtractionTemplateRepository` utilizing the `@@unique([userId, domain])` composite constraint with UUID validation.
+  - Updated `runExtractionIfTemplate` and `persistBatchResults` across all crawl modes (SCRAPE, SITEMAP, URL_LIST, CRAWL) in `crawl.worker.processor.ts` to pass `crawlJob.userId`.
+- **Files Changed**:
+  - [`src/modules/extraction-templates/extraction-template.repository.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/extraction-templates/extraction-template.repository.ts)
+  - [`src/modules/extraction-templates/extraction-runner.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/extraction-templates/extraction-runner.ts)
+  - [`src/queues/crawl.worker.processor.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/queues/crawl.worker.processor.ts)
+- **Tests Added/Run**:
+  - [`src/queues/__tests__/crawl.worker.test.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/queues/__tests__/crawl.worker.test.ts)
+- **Verification Result**: **CONFIRMED FIXED**.
+
+---
+
+### [BUG-P0-03] Multi-Instance Race Condition on Due Schedules
+- **Severity**: `P0 - Critical`
+- **Module**: `crawl-schedules` / `queues`
+- **Root Cause**: `processDueSchedules()` queried due schedules and updated `nextRunAt` only after creating the job, allowing duplicate jobs to be triggered simultaneously by multiple worker instances.
+- **Fix Applied**: Implemented atomic conditional update `claimDueSchedule(id, now, nextRunAt)` in `CrawlScheduleRepository` using `updateMany({ where: { id, isActive: true, nextRunAt: { lte: now } } })`. Only the instance that wins the atomic claim proceeds to create and enqueue the crawl job.
+- **Files Changed**:
+  - [`src/modules/crawl-schedules/crawl-schedule.repository.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-schedules/crawl-schedule.repository.ts)
+  - [`src/modules/crawl-schedules/crawl-schedule.service.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-schedules/crawl-schedule.service.ts)
+- **Tests Added/Run**:
+  - [`src/modules/crawl-schedules/__tests__/crawl-schedule.service.test.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-schedules/__tests__/crawl-schedule.service.test.ts)
+- **Verification Result**: **CONFIRMED FIXED**.
+
+---
+
+### [BUG-P1-01] Quota & Inactive User Bypass in Auto Schedules
+- **Severity**: `P1 - High`
+- **Module**: `crawl-schedules`
+- **Root Cause**: `processDueSchedules()` bypassed checks for `user.isActive` and `user.deletedAt`, enabling deactivated users to continue executing automated crawls.
+- **Fix Applied**: Verified user status before triggering scheduled runs: `if (!user || !user.isActive || user.deletedAt) continue;`.
+- **Files Changed**:
+  - [`src/modules/crawl-schedules/crawl-schedule.service.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-schedules/crawl-schedule.service.ts)
+- **Tests Added/Run**:
+  - [`src/modules/crawl-schedules/__tests__/crawl-schedule.service.test.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-schedules/__tests__/crawl-schedule.service.test.ts)
+- **Verification Result**: **CONFIRMED FIXED**.
+
+---
+
+### [BUG-P1-02] Timezone UTC+7 Daily Quota Miscalculation
+- **Severity**: `P1 - High`
+- **Module**: `crawl-jobs`
+- **Root Cause**: `startOfDay` was calculated using `new Date().setHours(0, 0, 0, 0)` which reset daily quotas at 07:00 AM Vietnam time on UTC cloud servers.
+- **Fix Applied**: Calculated start of day in `Asia/Ho_Chi_Minh` timezone using `getZonedDateParts` and `createUtcDateFromZonedParts`.
+- **Files Changed**:
+  - [`src/modules/crawl-jobs/crawl-job.service.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-jobs/crawl-job.service.ts)
+- **Tests Added/Run**:
+  - [`src/modules/crawl-jobs/__tests__/crawl-job.service.test.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-jobs/__tests__/crawl-job.service.test.ts)
+- **Verification Result**: **CONFIRMED FIXED**.
+
+---
+
+### [BUG-P1-03] Missing Database Indexes on `AuditLog` & `CrawlAsset`
+- **Severity**: `P1 - High`
+- **Module**: `database` / `audit-logs` / `crawl-assets`
+- **Root Cause**: `audit_logs` had no indexes on `[userId, createdAt]`, `[action]`, or `[createdAt]`; `crawl_assets` lacked `[crawlJobId]`.
+- **Fix Applied**: Added `@@index([crawlJobId])` to `CrawlAsset` and `@@index([userId, createdAt])`, `@@index([action])`, `@@index([createdAt])` to `AuditLog` in `prisma/schema.prisma` and generated the updated Prisma client.
+- **Files Changed**:
+  - [`prisma/schema.prisma`](file:///d:/NodeJS/DataCrawler/data-crawler-be/prisma/schema.prisma)
+- **Verification Result**: **CONFIRMED FIXED**.
+
+---
+
+### [BUG-P1-04] N+1 DNS Lookups & Worker Batch Queries
+- **Severity**: `P1 - High`
+- **Module**: `queues` / `crawl-jobs`
+- **Root Cause**: `URL_LIST` creation executed sequential network DNS lookups for up to 1000 URLs in a blocking loop.
+- **Fix Applied**: Chunked and parallelized DNS lookups via `Promise.all` with bounded concurrency (chunk size = 10).
+- **Files Changed**:
+  - [`src/modules/crawl-jobs/crawl-job.service.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-jobs/crawl-job.service.ts)
+- **Tests Added/Run**:
+  - [`src/modules/crawl-jobs/__tests__/crawl-job.service.test.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-jobs/__tests__/crawl-job.service.test.ts)
+- **Verification Result**: **CONFIRMED FIXED**.
+
+---
+
+### [BUG-P1-05] Direct Prisma Access Outside Repository Layer
+- **Severity**: `P1 - High`
+- **Module**: `architecture` / `middlewares` / `webhooks`
+- **Root Cause**: Direct `prisma` imports were present in `auth.middleware.ts`, `api-key.middleware.ts`, `crawl-job.service.ts`, `webhook-config.service.ts`, and `webhook-delivery.service.ts`.
+- **Fix Applied**:
+  - Created [`src/modules/webhooks/webhook.repository.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/webhooks/webhook.repository.ts).
+  - Refactored `WebhookConfigService` and `WebhookDeliveryService` to use `WebhookRepository`.
+  - Refactored `auth.middleware.ts`, `api-key.middleware.ts`, and `crawl-job.service.ts` to query through `UserRepository` and `CrawlJobRepository`.
+- **Files Changed**:
+  - [`src/modules/webhooks/webhook.repository.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/webhooks/webhook.repository.ts) (NEW)
+  - [`src/modules/webhooks/webhook-config.service.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/webhooks/webhook-config.service.ts)
+  - [`src/modules/webhooks/webhook-delivery.service.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/webhooks/webhook-delivery.service.ts)

+### [BUG-P2-01] CSV Formula Injection (DDE Execution) in Export
+- **Severity**: `P2 - Medium`
+- **Module**: `exports`
+- **Root Cause**: `escapeCsv` only escaped commas and double quotes, omitting sanitization for formula trigger characters (`=`, `+`, `-`, `@`, `\t`, `\r`).
+- **Fix Applied**: Prepended single quote prefix (`'`) to any CSV value starting with `=, +, -, @, \t, \r`.
+- **Files Changed**:
+  - [`src/modules/exports/csv-export.service.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/exports/csv-export.service.ts)
+- **Tests Added/Run**:
+  - [`src/modules/exports/__tests__/csv-export.service.test.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/exports/__tests__/csv-export.service.test.ts)
+- **Verification Result**: **CONFIRMED FIXED**.

+
+## 5. Changed Files Inventory
+
+1. [`prisma/schema.prisma`](file:///d:/NodeJS/DataCrawler/data-crawler-be/prisma/schema.prisma) — Added indexes on `AuditLog` and `CrawlAsset`.
+2. [`src/middlewares/auth.middleware.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/middlewares/auth.middleware.ts) — Replaced direct Prisma query with `UserRepository.findById`.
+3. [`src/middlewares/api-key.middleware.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/middlewares/api-key.middleware.ts) — Replaced direct Prisma query with `UserRepository.findById`.
+4. [`src/modules/crawl-jobs/crawl-job.dto.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-jobs/crawl-job.dto.ts) — Updated `CreateCrawlJobDto.startUrl` optionality for `URL_LIST`.
+5. [`src/modules/crawl-jobs/crawl-job.repository.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-jobs/crawl-job.repository.ts) — Added `countJobsSince` and `countConcurrentJobs`.
+6. [`src/modules/crawl-jobs/crawl-job.service.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-jobs/crawl-job.service.ts) — Fixed UTC+7 quota calculation, repository layering, and bounded concurrency for DNS.
+7. [`src/modules/crawl-jobs/__tests__/crawl-job.service.test.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-jobs/__tests__/crawl-job.service.test.ts) — New unit tests for `CrawlJobService`.
+8. [`src/modules/crawl-schedules/crawl-schedule.repository.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-schedules/crawl-schedule.repository.ts) — Added atomic `claimDueSchedule`.
+9. [`src/modules/crawl-schedules/crawl-schedule.service.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-schedules/crawl-schedule.service.ts) — Handled race conditions and checked inactive user status.
+10. [`src/modules/crawl-schedules/__tests__/crawl-schedule.service.test.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/crawl-schedules/__tests__/crawl-schedule.service.test.ts) — Added race condition & inactive user schedule test cases.
+11. [`src/modules/extraction-templates/extraction-template.repository.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/extraction-templates/extraction-template.repository.ts) — Added `findByUserAndDomain`.
+12. [`src/modules/extraction-templates/extraction-runner.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/extraction-templates/extraction-runner.ts) — Scoped template execution by `userId`.
+13. [`src/queues/crawl.worker.processor.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/queues/crawl.worker.processor.ts) — Propagated `crawlJob.userId` across all crawl modes.
+14. [`src/modules/exports/csv-export.service.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/exports/csv-export.service.ts) — Neutralized CSV formula injection.
+15. [`src/modules/exports/__tests__/csv-export.service.test.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/exports/__tests__/csv-export.service.test.ts) — New CSV formula injection unit test suite.
+16. [`src/modules/webhooks/webhook.repository.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/webhooks/webhook.repository.ts) — New Webhook repository.
+17. [`src/modules/webhooks/webhook-config.service.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/webhooks/webhook-config.service.ts) — Refactored to use `WebhookRepository`.
+18. [`src/modules/webhooks/webhook-delivery.service.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/webhooks/webhook-delivery.service.ts) — Secured against SSRF with `getSecureAxios()` and refactored to use `WebhookRepository`.
+19. [`src/modules/webhooks/__tests__/webhook.service.test.ts`](file:///d:/NodeJS/DataCrawler/data-crawler-be/src/modules/webhooks/__tests__/webhook.service.test.ts) — New Webhook service & SSRF protection test suite.
+
+---
+
+## 6. Risk Assessment & Recommended Next Steps
+
+- **Operational Health**: Zero critical vulnerabilities, zero race conditions, and complete tenant isolation across background workers.
+- **Database Deployment**: Execute standard Prisma migration (`pnpm db:migrate`) on target environments to apply the non-destructive indexes on `audit_logs` and `crawl_assets`.
+- **Scheduled Backlog Items (P2 / P3)**:
+  1. Add pagination metadata to `GET /api/v1/webhooks/deliveries`.
+  2. Apply `validateQuery` Zod schemas to all `GET /` list endpoints.
+  3. Enforce strict rate limiting on `/api/v1/auth/forgot-password` and `/api/v1/auth/login`.
