## What changed
- Update the required pull request attribution to `Generated with [Codex](https://openai.com/codex/).`.
- Recognize the previous unlinked attribution when restoring saved context so it can be replaced without duplicating the attribution instructions.
## Testing
- Cover cold resume with both commit-only legacy instructions and the previous unlinked pull request attribution.
- Update app-server and MCP server assertions for the linked attribution.

## What changed
- Install the git attribution extension in the app server, MCP server, and `codex debug prompt-input` so authenticated workspace policy controls the commit and pull request attribution instructions sent to the model.
- Resolve attribution settings from the process-level ChatGPT base URL, independent of per-thread or per-tool configuration overrides.
- Treat git attribution as contextual developer content when mapping model events.
## Testing
- Cover policy fetch retries, workspace switches, rollbacks, cold thread resumes with legacy instructions, MCP tool calls, and prompt-debug output.
