Transcript files are not found for Copilot Cloud Agent

What happened?

Using entire in Copilot Cloud Agent sessions results in:

failed to extract session data from live transcript: transcript not found at /home/runner/.copilot/session-state/<session-id>/events.jsonl (also tried /home/runner/.copilot/session-state/<session-id>/events/events.jsonl): file does not exist

This seems related to https://github.com/github/gh-aw-firewall/issues/1466.

Steps to reproduce

1. Ensure the repository has the given agent enabled: entire enable --agent copilot-cli
2. Add workflow to install entire:

name: "Copilot Setup Steps"

on:
  workflow_dispatch:
  push:
    paths:
      - .github/workflows/copilot-setup-steps.yml
  pull_request:
    paths:
      - .github/workflows/copilot-setup-steps.yml

jobs:
  copilot-setup-steps:
    runs-on: ubuntu-latest

    permissions:
      contents: read

    steps:
      - name: Install Entire CLI
        run: go install github.com/entireio/cli/cmd/entire@latest

      - name: Add Entire to path
        run: echo $(go env GOPATH)/bin >> $GITHUB_PATH

3. Ensure both changes are committed and pushed to main.
4. In the Agents tab (https://github.com/<org>/<repo>/agents) start a new session:

Run "entire enable".

Ask for the change to be made (e.g. Create README file)

Commit the changes

Run "entire status"

Push changes

Run the commands:
git show entire/checkpoints/v1
cat .entire/logs/entire.log

This results in the trailer being added to the commit in the branch that Copilot creates. However, no checkpoint is pushed to the checkpoint remote/branch. In the logs the transcript is shown as file does not exist.

Additional context

Under the same conditions, picking Claude Code as the agent worked with and without the Copilot Cloud Agent firewall enabled. For both Codex and Copilot CLI that didn't work.
