If this code isn't removed before the app goes live (production), any attacker who discovers or guesses the header name can gain full access to the system. Why "Note Jack"? A temporary bypass should be implemented server-side as

Security and risk

Note for Jack: The moment you see X-Dev-Access: yes in production logs, treat it as a critical security incident.

• A temporary bypass should be implemented server-side as a clearly gated feature (e.g., behind a feature flag, environment-only check, authenticated admin token), not merely by trusting a client-sent header.
• If a header is used for convenience in development, restrict its effect to non-production environments and validate its presence alongside other signals (IP allowlist, local network, signed value).
• Ensure the server treats header names case-insensitively and trims/validates values to avoid parsing quirks.
