# Documentation Audit Report

- **Auditor Role**: Documentation Engineer
- **Date**: 2026-08-06
- **Repository HEAD**: `715873b2ecc3a72ba974bb2a2be87c5ba82bd4e7`
- **Included Scope**: `README.md`, `backend/README.md`, `swagger.yml`, `BACKEND_INTEGRATION.md`, `DATABASE_SCHEMA.md`.
- **Excluded Scope**: Non-markdown files except for content cross-referencing.
- **Files Inspected**: `README.md`, `swagger.yml`, `BACKEND_INTEGRATION.md`, `DATABASE_SCHEMA.md`, `backend/src/auth/auth.controller.ts`.
- **Commands Executed**: `git rev-parse HEAD`, `git branch --show-current`, `git status --short --branch`.
- **Commands Blocked**: None.
- **Audit Limitations**: Evaluated strictly by comparing implementation source against documentation statements.

## Domain Overview & Confirmed Strengths
- **Comprehensive Technical Markdown Files**: `BACKEND_INTEGRATION.md` and `DATABASE_SCHEMA.md` provide detailed architectural diagrams, schema breakdowns, and setup instructions.

## Findings

## DOC-001

### Title
Static Swagger Specification Desynchronization with Active NestJS Auth Endpoints

### Domain
Documentation

### Category
API Documentation Drift

### Severity
MEDIUM

### Confidence
CONFIRMED

### Status
OPEN

### Affected Application
Root Documentation (`swagger.yml`)

### Affected Files
- `swagger.yml`
- `backend/src/auth/auth.controller.ts`

### Relevant Symbols or Lines
- `swagger.yml#L15-L50`
- `backend/src/auth/auth.controller.ts#L24-L94`

### Evidence
In `swagger.yml`, authentication paths are documented under `/auth/login` and `/auth/register` taking email/password payloads. However, the NestJS backend implementation (`auth.controller.ts`) exposes `/auth/send-otp` and `/auth/verify-otp`.

### Problem
Static OpenAPI document (`swagger.yml`) contradicts active backend REST endpoints.

### Root Cause
`swagger.yml` was authored as a design draft before NestJS controllers implemented SMS OTP authentication.

### Why It Matters
External developers or API consumers relying on `swagger.yml` will construct invalid HTTP requests resulting in 404 Not Found errors.

### User or Business Impact
Frontend or mobile developers attempting third-party integration experience integration delays due to inaccurate documentation.

### Technical Impact
Inconsistent API specifications across the repository.

### Security or Data-Integrity Impact
Low security impact; integration accuracy impact.

### Recommended Direction
Regenerate or update `swagger.yml` from active `@nestjs/swagger` runtime decorators.

### Alternative Direction
Remove static `swagger.yml` and mandate dynamic NestJS `/api/docs` as single source of truth.

### Implementation Complexity
LOW

### Dependencies
None.

### Risks
None.

### Verification Requirements
Compare `swagger.yml` against NestJS Swagger output at `/api/docs-json`.

### Testing Requirements
Validate OpenAPI YAML syntax after update.

### Acceptance Criteria
`swagger.yml` endpoints match active NestJS controller decorators.

### Notes and Limitations
None.
