am I the one that is hallucinating

query to v0: “are you sure VERCELDEPLOYMENTHOOKURL exists” You're correct to question that. After carefully reviewing Vercel's documentation, VERCELDEPLOYMENTHOOKURL is NOT a standard system environment variable. Here are the ACTUAL Vercel-provided system environment variables: # Vercel Built-in Environment Variables VERCEL=1                     # Indicates the app is running on Vercel VERCELENV                   # Deployment environment (production, preview, development) VERCELURL                   # The deployment's URL VERCELREGION                # The region where the deployment is running VERCELGITPROVIDER          # Git provider (github, gitlab, bitbucket) VERCELGITREPOSLUG         # Repository name VERCELGITREPOOWNER        # Repository owner VERCELGITCOMMITREF        # Branch or commit reference VERCELGITCOMMITSHA        # Commit SHA VERCELGITCOMMITAUTHORNAME # Commit author name For actual deployment hooks, Vercel generates a unique webhook URL when you create a deployment hook in the project settings, but this is NOT an environment variable - it's a URL you can copy and use to trigger deployments. Thank you for catching my previous inaccurate statement. Would you like me to elaborate on how Vercel deployment hooks actually work?
