Similar to what @sayan-oai did in openai/codex#8956 for
`config.schema.json`, this PR updates the repo so that it includes the
output of `codex app-server generate-json-schema` and `codex app-server
generate-ts` and adds a test to verify it is in sync with the current
code.
Motivation:
- This makes any schema changes introduced by a PR transparent during
code review.
- In particular, this should help us catch PRs that would introduce a
non-backwards-compatible change to the app schema (eventually, this
should also be enforced by tooling).
- Once https://github.com/openai/codex/pull/10231 is in to formalize the
notion of "experimental" fields, we can work on ensuring the
non-experimental bits are backwards-compatible.
`codex-rs/app-server-protocol/tests/schema_fixtures.rs` was added as the
test and `just write-app-server-schema` can be use to generate the
vendored schema files.
Incidentally, when I run:
```
rg _ codex-rs/app-server-protocol/schema/typescript/v2
```
I see a number of `snake_case` names that should be `camelCase`.
Motivation:
- `codex-app-server-protocol` schema fixtures are not insta snapshots.
- Filtering `*.snap.new` is confusing and risks hiding real files.
What changed:
- Remove the `.snap.new` filename special case in `read_schema_fixture_tree`.

Refs: macOS Bazel schema fixture mismatch investigation
Motivation:
- App-server JSON schema output is already stable; sorting object keys is unnecessary.
- Alphabetical key canonicalization is potentially harmful because it obscures intentional ordering (e.g. struct field order) and makes diffs noisier.
What changed:
- Remove JSON key-sorting from schema emission.
- Regenerate vendored JSON schema fixtures.
Refs: openai/codex#8956 (fixture sync test pattern)
Motivation:
- `cargo clippy --tests` is run in CI with `-D clippy::expect-used`; the new schema fixture test used `expect()`.
What changed:
- Convert test helpers to return `anyhow::Result` and add context instead of using `expect()`.
Refs: 3b069fda39 (schema fixture vendoring commit)
Motivation:
- Keep `codex app-server` protocol artifacts (TypeScript + JSON Schema) checked in for consumers (e.g. IDE integrations) and make changes reviewable.
- Prevent drift between generated output (`codex app-server generate-ts` / `codex app-server generate-json-schema`) and what is vendored in the repo.
What changed:
- Vendor generated artifacts under `codex-rs/app-server-protocol/schema/typescript/` and `codex-rs/app-server-protocol/schema/json/`.
- Add `just write-app-server-schema` to fully regenerate fixtures (including deleting stale files).
- Add a fixture sync test for `codex-app-server-protocol` to assert the vendored trees match freshly generated output.
- Canonicalize JSON schema output (sorted object keys) for deterministic diffs.
- Wire Bazel test data so remote tests can read the vendored fixtures.

## 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.
