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.
