# Security Audit: Authentication & Authorization

## Executive Summary

The security audit of authentication and authorization mechanisms for the Poindexter repository has been completed. The investigation concludes that the codebase is a Go library providing data structures and algorithms, specifically k-d trees and sorting utilities. It does not contain any user-facing application, authentication flows, authorization logic, or session management. Therefore, the requested audit categories are not applicable.

## Scope of Review

The audit was initiated to assess the following areas:
- **Authentication:** Password handling, session management, token security, and multi-factor authentication.
- **Authorization:** Access control models, permission checks, privilege escalation vulnerabilities, and API protection.

## Findings

A thorough review of the codebase was conducted, including but not limited to the following files:
- `README.md`
- `poindexter.go`
- `kdtree.go`
- `CLAUDE.md`
- `npm/poindexter-wasm/smoke.mjs`
- `wasm/main.go`
- `go.mod`

The analysis of these files confirms that the repository contains a library and not a service or application. There are no functions or modules related to:
- User registration or login
- Password hashing or storage
- Session or token generation
- Access control lists (ACLs), role-based access control (RBAC), or other authorization models
- API endpoints requiring protection

## Conclusion

The Poindexter library, by its nature, does not handle authentication or authorization. As such, there are no vulnerabilities to report in these areas. The audit is concluded as not applicable.
