Please inspect the backend project located in the current directory, determine its programming language and architectural style, and then complete the following code implementation and environment setup tasks.\n\nImplement the root health checks in `examples/users-api/server.js` so the Express server can respond to monitoring probes.\n\nRequirements\n1. Inside the `app.head('/', \u2026)` handler, reply immediately with HTTP 200 and the plain text body `ok` (all lowercase). No JSON encoding and no additional headers are required beyond what Express sets automatically.\n2. Inside the `app.get('/', \u2026)` handler, reply with HTTP 200 and the plain text body `OK` (uppercase). This endpoint is the human-readable version of the health check and should match the casing exactly.\n3. Neither handler should depend on the Auth0 middleware or any request state; they must always return the healthy response as long as the process is running.\n4. Keep the handlers synchronous and lightweight\u2014no asynchronous operations or external dependencies belong in these probes.\n\nFollow the existing Express patterns already present in the server (directly using the `res` object for status and body).\nPlease locate the appropriate place in the project and apply the necessary modifications.\n\nAfter completing all source code implementation, create a Dockerfile for this project using the following example template as a reference (Python version):\n```\n# setup base\nFROM nikolaik/python-nodejs:python3.12-nodejs22-bullseye\nRUN apt-get update && apt-get install -y sqlite3\n\n# install dependencies and copy project files\nWORKDIR /app\nCOPY . /app/\nRUN python3 -m pip install -r requirements.txt\n\nENTRYPOINT [\"python3\", \"app.py\"]\n```\nNotes:\n1. Ensure that all required project dependencies are properly installed inside the image.\n2. The generated Dockerfile must successfully build and run the application.\n3. The Dockerfile must be created in the root directory of the backend project, i.e `/app/auth0_auth0-react/Dockerfile`\n", "memory": "", "runnable": false, "difficulty": "hard", "language": "", "cpus": "", "instruction_truncated": false, "category": "DevTools", "compose": true, "has_solution": true, "oracle": null, "docker_image": "", "taskset": "abc-bench", "tags": []}, "runs": []}
