## Why
Follow-up to #20291.
The v2 item-event-to-notification translation had been embedded in
`app-server/src/bespoke_event_handling.rs`, which made it hard to reuse
anywhere else. This PR moves that stateless mapping into shared protocol
code so other entry points can produce the same `ServerNotification`
payloads without copying app-server logic.
That also lets `thread-manager-sample` demonstrate the same notification
surface that the app server exposes, instead of only printing the final
assistant message.
## What changed
- move `item_event_to_server_notification` into
`codex-app-server-protocol::protocol::event_mapping`
- keep the mapper tests next to the shared implementation in
`codex-app-server-protocol`
- re-export the mapper from `codex-core-api` so lightweight consumers
can use it without reaching into `app-server-protocol` directly
- simplify `app-server/src/bespoke_event_handling.rs` so it delegates
the stateless event-to-notification projection to the shared helper
- update `thread-manager-sample` to:
- print mapped notifications as newline-delimited JSON
- use the shared mapper through `codex-core-api`
- enable the default feature set so the sample exposes the normal tool
surface
- use a `read_only` permission profile so shell commands can run in the
sample without widening permissions
## Testing
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-core-api`
- `cargo test -p codex-app-server bespoke_event_handling::tests`
- `cargo test -p codex-thread-manager-sample`
- `cargo run -p codex-thread-manager-sample -- "briefly explore the repo
with pwd and ls, then summarize it"`
Summary:
- Add a checked-in codex-core public API listing generated by
cargo-public-api.
- Add scripts/regen-public-api.sh with an embedded crate list,
auto-install for cargo-public-api 0.51.0, pinned nightly, and --check
mode.
- Add Rust CI jobs on the codex Linux x64 runner pool to verify the
listing stays up to date.
Testing:
- bash -n scripts/regen-public-api.sh
- just regen-public-api --check
- yq '.' .github/workflows/rust-ci.yml
.github/workflows/rust-ci-full.yml
- git diff --check
Summary:
- Add codex-thread-manager-sample, a one-shot binary that starts a
ThreadManager thread, submits a prompt, and prints the final assistant
output.
- Pass ThreadStore into ThreadManager::new and expose
thread_store_from_config for existing callsites.
- Build the sample Config directly with only --model and prompt inputs.
Verification:
- just fmt
- cargo check -p codex-thread-manager-sample -p codex-app-server -p
codex-mcp-server
- git diff --check
Tests: Not run per request.
