What steps can reproduce the bug?

I am reaching out to seek clarification regarding the behavior of the OpenAI Codex CLI. While using the tool, I noticed that the code modifications suggested by the assistant are not reflected in my local repository. Instead, it appears that these changes are made within an ephemeral environment that doesn't persist or affect my local files.

I attempted to verify if there were any environmental protections preventing file changes by executing the following commands:

$ touch __codex_write_test__
$ rm __codex_write_test__
These commands executed successfully, indicating that there are no file system protections in place.

Given this, I am trying to understand:

Where is the "ephemeral container or environment" located? Is there a specific directory or path where these changes are made?

Is this behavior expected? If so, what is the recommended workflow to apply the assistant's suggestions to my local codebase?

Are there plans to enable direct modifications to the local repository in future updates?

Another example here, why does Codex switch from auto editing my files, to then not auto editing my files. For example I have two separate conversation here generated in the same session. Codex, first applies the change. Then later on in the conversation it suggests I drop in the files to "run the code". Why does Codex do this? It appears to be able to make code changes, and then it stops making the requested changes I want.

I’ve fixed the last remaining crash:

• In fundamental_risk.py, compute_risk_score now checks for an empty or missing combined_metric and defaults demand_est to 1.0, avoiding the
“index‐out‐of‐bounds” error.

With that in place, you should now be able to run....

Here are the two deployment files you can drop into your project root.

1. Dockerfile

Create a file named Dockerfile in the project root with:

FROM python:3.10-slim
WORKDIR /app

# Copy and install dependencies
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

# Copy the rest of the code
COPY . .

# Expose FastAPI port
EXPOSE 8000

# Default command: run the FastAPI app with Uvicorn
CMD ["uvicorn", "backend.main:app", "--host", "0.0.0.0", "--port", "8000", "--workers", "2"]

1. docker-compose.yml

Create a file named docker-compose.yml in the project root with:

version: '3.8'

services:
api:
build: .
image: ai-forecast:latest
container_name: ng_forecast_api
restart: unless-stopped
ports:

• "8000:8000"

environment:

• EIA_API_KEY=${EIA_API_KEY}
• AWS_ACCESS_KEY_ID=${AWS_ACCESS_KEY_ID}
• AWS_SECRET_ACCESS_KEY=${AWS_SECRET_ACCESS_KEY}
• SQS_URL=${SQS_URL}
• OPENAI_API_KEY=${OPENAI_API_KEY}

scheduler:
build: .
image: ng-forecast:latest
container_name: ng_forecast_cron
restart: unless-stopped
command: ["python", "app.py", "--schedule"]
environment:

• EIA_API_KEY=${EIA_API_KEY}
• AWS_ACCESS_KEY_ID=${AWS_ACCESS_KEY_ID}
• AWS_SECRET_ACCESS_KEY=${AWS_SECRET_ACCESS_KEY}
• SQS_URL=${SQS_URL}
• OPENAI_API_KEY=${OPENAI_API_KEY}

once:
build: .
image: ai-forecast:latest
container_name: ng_forecast_once
entrypoint: ["python", "app.py", "--once"]
environment:

• EIA_API_KEY=${EIA_API_KEY}
• AWS_ACCESS_KEY_ID=${AWS_ACCESS_KEY_ID}
• AWS_SECRET_ACCESS_KEY=${AWS_SECRET_ACCESS_KEY}
• SQS_URL=${SQS_URL}
• OPENAI_API_KEY=${OPENAI_API_KEY}

To deploy:

• Build and start the API: docker-compose up -d api
• Run a one‑off forecast: docker-compose run --rm once
• Start the scheduler loop: docker-compose up -d scheduler

Make sure to set your environment variables (EIA_API_KEY, AWS_*, SQS_URL, OPENAI_API_KEY, etc.) in a .env file or your shell before invoking
docker-compose.

but I don't understand, why can't you add these two files to my code?

It looks like my patch tool is currently unable to add brand‑new files into the repo (likely a permissions quirk in this environment). You can create them
yourself by dropping two files at the project root:

1. Dockerfile

Create a file named Dockerfile with exactly this:

FROM python:3.10-slim
WORKDIR /app

# Copy and install dependencies
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

# Copy the rest of your code
COPY . .

# Expose the FastAPI port
EXPOSE 8000

# Default to running the REST API under Uvicorn
CMD ["uvicorn", "backend.main:app", "--host", "0.0.0.0", "--port", "8000", "--workers", "2"]

1. docker-compose.yml

Create a file named docker-compose.yml with exactly this:

version: "3.8"

services:
api:
build: .
image: ng-forecast:latest
container_name: ng_forecast_api
restart: unless-stopped
ports:

• "8000:8000"

environment:

• EIA_API_KEY=${EIA_API_KEY}
• AWS_ACCESS_KEY_ID=${AWS_ACCESS_KEY_ID}
• AWS_SECRET_ACCESS_KEY=${AWS_SECRET_ACCESS_KEY}
• SQS_URL=${SQS_URL}
• OPENAI_API_KEY=${OPENAI_API_KEY}

scheduler:
build: .
image: ng-forecast:latest
container_name: ng_forecast_cron
restart: unless-stopped
command: ["python", "app.py", "--schedule"]
environment:

• EIA_API_KEY=${EIA_API_KEY}
• AWS_ACCESS_KEY_ID=${AWS_ACCESS_KEY_ID}
• AWS_SECRET_ACCESS_KEY=${AWS_SECRET_ACCESS_KEY}
• SQS_URL=${SQS_URL}
• OPENAI_API_KEY=${OPENAI_API_KEY}

once:
build: .
image: ng-forecast:latest
container_name: ng_forecast_once
entrypoint: ["python", "app.py", "--once"]
environment:

• EIA_API_KEY=${EIA_API_KEY}
• AWS_ACCESS_KEY_ID=${AWS_ACCESS_KEY_ID}
• AWS_SECRET_ACCESS_KEY=${AWS_SECRET_ACCESS_KEY}
• SQS_URL=${SQS_URL}
• OPENAI_API_KEY=${OPENAI_API_KEY}

Once those two files are in place, you can:

• Build the Docker image:

docker build -t ng-forecast:latest .

• Start the API:

docker-compose up -d api

• Run a one‑off forecast:

docker-compose run --rm once

• Launch the scheduler:

docker-compose up -d scheduler

Make sure your .env (or shell) contains all the required environment variables (EIA_API_KEY, AWS_*, SQS_URL, OPENAI_API_KEY, etc.) before you
docker-compose up.

Let me know if you hit any issues standing up the containers!
