### NestJS 11 + Next.js 16 Migration (2026-03-16)

#### Backend 🔧

- **NestJS 11 Upgrade**: `@nestjs/*` v11, Express v5, removed `@nestjs/mapped-types`
- **RequestWithUser Interface**: Shared typed interface replacing `req: any` across 6 controllers (`auth`, `session`, `file-storage`, `workflow-engine`, `correspondence`, `jwt-refresh`)
- **MasterModule DI Fix**: Imported `UserModule` so `RbacGuard` can resolve `UserService`
- **TypeORM Fix**: Explicit typing for `DocumentNumberFormat` save/create overload resolution
- **Swagger**: Updated API version to 1.8.1

#### Frontend 🎨

- **Next.js 16 Upgrade**: Next.js 16.0.7, React 19
- **proxy.ts Rename**: `middleware.ts` → `proxy.ts` (Next.js 16 deprecated `middleware` convention)
- **ADR-019 UUID Fixes — Drawing Admin Pages (5 pages)**:
  - `contract/volumes`, `contract/categories`, `contract/sub-categories`
  - `shop/main-categories`, `shop/sub-categories`
  - Changed `useState<number>` → `useState<string>`, removed `parseInt(uuid)`
- **ADR-019 UUID Fixes — Contract Page**:
  - Fixed edit form showing "New Contract" (`contract.uuid` → `contract.id` after `@Expose`)
  - Fixed blank Project dropdown (was using contract's UUID instead of project's UUID)
  - Fixed delete passing `undefined` uuid
  - Updated `Contract` interface to match serialized API response
- **ADR-019 UUID Fixes — Disciplines & RFA Types**:
  - `useContracts(projectId=1)` → optional param, fetches all contracts when unspecified
  - `useDisciplines(contractId?: number)` → `number | string`
- **ADR-019 UUID Fixes — Tags Page**:
  - Fixed Radix Select crash on empty `value=""` → `"__none__"` sentinel
  - Fixed Project Scope dropdown showing UUIDs (snake_case → camelCase field names)
- **DTO Updates**: `CreateContractDto`, `SearchContractDto`, `CreateShopMainCategoryDto`, etc. — `projectId: number` → `number | string`
- **Service Updates**: `drawing-master-data.service.ts`, `master-data.service.ts` — accept `string | number` for project/contract IDs

#### Documentation 📚

- **ADR-005**: Updated Backend Stack table (NestJS 11, Express v5)
- **Engineering Guidelines** (`05-01`): Added NestJS 11 specific patterns section

## 1.8.0 (2026-02-24)

### Summary

**Documentation Realignment & Type Safety** - Comprehensive overhaul of the specifications structure and frontend codebase to enforce strict typing and consistency.

### Codebase Changes 💻

- **Frontend Type Safety**: Removed all `any` types from Frontend DTOs and Hooks. Implemented explicit types (`AuditLog[]`, `Record<string, unknown>`) avoiding implicit fallbacks.
- **Frontend Refactoring**: Refactored data fetching and mutations utilizing `TanStack Query` hooks aligned with real API endpoints.
- **Admin Pages Fixes**: Addressed crashes on Reference Data/Categories pages by introducing robust error handling and proper generic typing on DataTables.

### Documentation 📚

- **Specification Restructuring**: Restructured the entire `specs/` directory into 7 canonical layers (`00-Overview`, `01-Requirements`, `02-Architecture`, `03-Data-and-Storage`, `04-Infrastructure-OPS`, `05-Engineering-Guidelines`, `06-Decision-Records`).
- **Guidelines Synchronization**: Updated Engineering Guidelines (`05-1` to `05-4`) to reflect the latest state management (Zustand, React Hook Form) and testing strategies.
- **ADR Alignment**: Audited Architecture Decision Records (ADR 1 to 16) against actual implementation (e.g., LocalStorage JWT vs HTTP-Only cookies, bcrypt salt rounds).
- **Root Docs Update**: Fully updated `README.md` and `CONTRIBUTING.md` to reflect the current v1.8.0 folder structure and rules.
- **Cleanups**: Consolidated standalone infrastructure specs (formerly `08-infrastructure`) into `04-Infrastructure-OPS` and cleaned up legacy scripts and blank diagrams from the repository root.

## 1.7.0 (2025-12-18)

### Summary

**Schema Stabilization & Document Numbering Overhaul** - Significant schema updates to support advanced document numbering (reservations, varying reset scopes) and a unified workflow engine.

### Database Schema Changes 💾

#### Document Numbering System (V2) 🔢

- **`document_number_counters`**:
  - **Breaking Change**: Primary Key changed to 8-column Composite Key (`project_id`, `originator_id`, `recipient_id`, `type_id`, `sub_type_id`, `rfa_type_id`, `discipline_id`, `reset_scope`).
  - **New Feature**: Added `reset_scope` column to support flexible resetting (YEAR, MONTH, PROJECT, NONE).
  - **New Feature**: Added `version` column for Optimistic Locking.
- **`document_number_reservations`** (NEW):
  - Implemented Two-Phase Commit pattern (Reserve -> Confirm) for document numbers.
  - Prevents race conditions and gaps in numbering.
- **`document_number_errors`** (NEW):
  - Helper table for tracking numbering failures and deadlocks.
- **`document_number_audit`**:
  - Enhanced with reservation tokens and performance metrics.

#### Unified Workflow Engine 🔄

- **`workflow_definitions`**:
  - Updated structure to support compiled DSL and versioning.
  - Added `dsl` (JSON) and `compiled` (JSON) columns.
- **`workflow_instances`**:
  - Changed ID to UUID.
  - Added `entity_type` and `entity_id` for polymorphic polymorphism.
- **`workflow_histories`**:
  - Updated to link with UUID instances.

#### System & Audit 🛡️

- **`audit_logs`**:
  - Updated schema for better partitioning support (`created_at` in PK).
  - Standardized JSON details column.
- **`notifications`**:
  - Updated schema to support polymorphic entity linking.

#### Master Data

- **`disciplines`**:
  - Added relation to `correspondences` and `rfas`.

### Documentation 📚

- **Data Dictionary**: Updated to v1.7.0 with full index summaries and business rules.
- **Schema**: Released `lcbp3-v1.7.0-schema.sql` and `lcbp3-v1.7.0-seed.sql`.

## 1.6.0 (2025-12-13)

### Summary

**Schema Refactoring Release** - Major restructuring of correspondence and RFA tables for improved data consistency.

### Database Schema Changes 💾

#### Breaking Changes ⚠️

- **`correspondence_recipients`**: FK changed from `correspondence_revisions(correspondence_id)` → `correspondences(id)`
- **`rfa_items`**: Column renamed `rfarev_correspondence_id` → `rfa_revision_id`

#### Schema Refactoring

- **`correspondences`**: Reordered columns, `discipline_id` now inline (no ALTER TABLE)
- **`correspondence_revisions`**:
  - Renamed: `title` → `subject`
  - Added: `body TEXT`, `remarks TEXT`, `schema_version INT`
  - Added Virtual Columns: `v_ref_project_id`, `v_doc_subtype`
- **`rfas`**:
  - Changed to Shared PK pattern (no AUTO_INCREMENT)
  - PK now FK to `correspondences(id)`
- **`rfa_revisions`**:
  - Removed: `correspondence_id` (uses rfas.id instead)
  - Renamed: `title` → `subject`
  - Added: `body TEXT`, `remarks TEXT`, `due_date DATETIME`, `schema_version INT`
  - Added Virtual Column: `v_ref_drawing_count`

### Documentation 📚
