## Summary
We ideally shouldn't make it to this point in the first place, but if we
do try to append a rule that already exists, we shouldn't append the
same rule twice.
## Testing
- [x] Added unit test for this case
## Summary
We should probably warn users that they have a million rules, and help
clean them up. But for now, we should handle this unbounded case.
Limit rules listed in conversations, with shortest / broadest rules
first.
## Testing
- [x] Updated unit tests
Updated system skills bundled with Codex were not correctly replacing
the user's skills in their .system folder.
- Fix `.codex-system-skills.marker` not updating by hashing embedded
system skills recursively (nested dirs + file contents), so updates
trigger a reinstall.
- Added a build Cargo hook to rerun if there are changes in
`src/skills/assets/samples/*`, ensuring embedded skill updates rebuild
correctly under caching.
- Add a small unit test to ensure nested entries are included in the
fingerprint.
## Summary
- Touch restored rollout files on `thread/unarchive` so `updatedAt`
reflects the unarchive time.
- Add a regression test to ensure unarchiving bumps `updated_at` from an
old mtime.
## Notes
This fixes the UX issue where unarchived old threads don’t reappear near
the top of recent threads.
## Summary
- Replace the “Hard interaction rule” with a clearer “Response
constraints” section that enumerates the allowed exceptions for Plan
Mode replies.
- Remove the stray Phase 1 exception line about simple questions.
- Update plan content requirements to ask for a brief summary section
and generalize API/type wording.
Summary
- expose websocket telemetry hooks through the responses client so
request durations and event processing can be reported
- record websocket request/event metrics and emit runtime telemetry
events that the history UI now surfaces
- improve tests to cover websocket telemetry reporting and guard runtime
summary updates

### Motivation
- The image referenced in the package README was 404ing on the npm
package page because it used a relative file path that doesn't resolve
on npm, so the splash image needs a GitHub-hosted URL to render
correctly.
### Description
- Update `README.md` to replace the relative image path
`./.github/codex-cli-splash.png` with the GitHub-hosted URL
`https://github.com/openai/codex/blob/main/.github/codex-cli-splash.png`.
### Testing
- No automated tests were run because this is a docs-only change and
does not affect code or test behavior.
