# Project Implementation Status Report

**Date:** 2025-12-08
**Report Type:** Comprehensive Audit Summary (Backend & Frontend)
**Status:** 🟢 Healthy / Advanced Progress

---

## 1. Executive Summary

This report summarizes the current implementation state of the **LCBP3-DMS** project.
- **Backend:** The core backend architecture and all primary business modules have been audited and **verified** as compliant with specifications. All critical path features are implemented.
- **Frontend:** The frontend user interface is approximately **80-85% complete**. All end-user modules (Correspondence, RFA, Drawings, Search, Dashboard) are implemented and integrated. The remaining work focuses on system configuration UIs (Admin tools for Workflow/Numbering).

## 2. Backend Implementation Status

**Audit Source:** `specs/06-tasks/backend-audit-results.md` (Verified Dec 8, 2025)
**Overall Backend Status:** ✅ **Completed** (Core Functional Requirements Met)

### ✅ Implemented Features (Verified)
| Module                 | ID     | Key Features Implemented                                                            | Note                                     |
| :--------------------- | :----- | :---------------------------------------------------------------------------------- | :--------------------------------------- |
| **Auth & RBAC**        | BE-002 | JWT, Session, Role Scopes (Global/Project), Permission Guards.                      | `UserAssignment` linking used correctly. |
| **User Mgmt**          | BE-013 | User CRUD, Preferences, User-Role Assignment.                                       |                                          |
| **Document Numbering** | BE-004 | **High Reliability**. Redlock (Redis) + Optimistic Locks + Audit Log.               | Critical infrastructure verified.        |
| **Correspondence**     | BE-005 | Application Logic, Master-Revision pattern, Workflow Submission, References.        |                                          |
| **RFA Module**         | BE-007 | RFA-Specific Logic, Item Management, Approval Workflow integration.                 |                                          |
| **Drawing Module**     | BE-008 | Separation of **Contract Drawings** (PDF) and **Shop Drawings** (Revisions).        | Metadata & Linkage logic verified.       |
| **Workflow Engine**    | BE-006 | **Hybrid Engine**. Supports modern DSL-based definitions AND legacy linear routing. | Robust fallback mechanism.               |
| **Search**             | BE-010 | Elasticsearch Integration. Full-text search and filtering.                          |                                          |
| **Master Data**        | BE-012 | Consolidated Master Service (Org, Project, Discipline, Types).                      | Simplifies maintenance.                  |

### ⚠️ Technical Notes / Minor Deviations
1.  **Workflow Engine:** Uses a hybrid approach. While fully functional, future refactoring could move strict "Routing Template" logic entirely into DSL to remove the "Legacy" support layer.
2.  **Search Indexing:** Currently uses **Direct Indexing** (service calls `searchService.indexDocument` directly) rather than a strictly decoupled **Queue Worker**. This ensures immediate consistency but may impact write latency under extreme load. For current scale, this is acceptable.

## 3. Frontend Implementation Status

**Audit Source:** `specs/06-tasks/frontend-progress-report.md` & `task.md`
**Overall Frontend Status:** 🟡 **In Progress** (~85% Complete)

### ✅ Implemented Features (Integrated)
The following modules have UI, Logic, and Backend Integration (Mock APIs removed):

| Module             | Features Implemented                                                  |
| :----------------- | :-------------------------------------------------------------------- |
| **Authentication** | Login, Token Management, RBAC (`<Can />`), Session Sync.              |
| **Layout & Nav**   | Responsive Sidebar, Header, Collapsible Structure, User Profile.      |
| **Correspondence** | List View, Create Form, Detail View, File Uploads.                    |
| **RFA**            | List View, Create RFA, RFA Item breakdown.                            |
| **Drawings**       | Contract Drawing List, Shop Drawing List, Upload Forms.               |
| **Global Search**  | Persistent Search Bar, Advanced Filtering Page (Project/Status/Date). |
| **Dashboard**      | KPI Cards, Activity Feed, Pending Tasks (Real data).                  |
| **Admin Panel**    | User Management, Organization Management, Audit Logs.                 |

### 🚧 Missing / Pending Features (To Be Implemented)
These features are defined in specs but not yet fully implemented in the frontend:

1.  **Workflow Configuration UI (`TASK-FE-011`)**
    *   **Status:** Not Started / Low Progress.
    *   **Requirement:** A drag-and-drop or form-based builder to manage the `WorkflowDefinition` DSL JSON.
    *   **Impact:** Currently workflows must be configured via SQL/JSON seeding or backend API tools.

2.  **Numbering Configuration UI (`TASK-FE-012`)**
    *   **Status:** Not Started / Low Progress.
    *   **Requirement:** UI to define "Numbering Formats" (e.g., `[PROJ]-[DISC]-[NSEQ]`) without DB access.
    *   **Impact:** Admin cannot easily change numbering formats.

---

## 4. Summary & Next Steps

### Critical Path (Immediate Priority)
The application is **usable** for day-to-day operations (Creating/Approving documents), making it "Feature Complete" for End Users. The missing pieces are primarily for **System Administrators**.

1.  **Frontend Admin Tools:**
    *   Implement **Workflow Config UI** (FE-011).
    *   Implement **Numbering Config UI** (FE-012).

2.  **End-to-End Testing:**
    *   Perform a full user journey test: *Login -> Create RFA -> Approve RFA -> Search for RFA -> Check Dashboard*.

### Recommendations
*   **Release Candidate:** The current codebase is sufficient for an "Alpha" release to end-users (Engineers/Managers) to validate data entry and basic flows.
*   **Configuration:** Defer the complex "Workflow Builder UI" if immediate release is needed; Admins can settle for JSON-based config initially.
