  • feat(cli): add codex doctor diagnostics (#22336)
    ## Why
    
    Users and support need a single command that captures the local Codex
    runtime, configuration, auth, terminal, network, and state shape without
    asking the user to know which diagnostic depth to choose first. `codex
    doctor` now runs the useful checks by default and makes the detailed
    human output the default because the command is usually run when someone
    already needs context.
    
    The command also targets concrete support failure modes we have seen
    while iterating on the design:
    
    - update-target mismatches like #21956, where the installed package
    manager target can differ from the running executable
    - terminal and multiplexer issues that depend on `TERM`, tmux/zellij
    state, color handling, and TTY metadata
    - provider-specific HTTP/WebSocket connectivity, including ChatGPT
    WebSocket handshakes and API-key/provider endpoint reachability
    - local state/log SQLite integrity problems and large rollout
    directories
    - feedback reports that need an attached, redacted diagnostic snapshot
    without asking the user to run a second command
    
    ## What Changed
    
    - Adds `codex doctor` as a grouped CLI diagnostic report with default
    detailed output and `--summary` for the compact view.
    - Adds stable report sections for Environment, Configuration, Updates,
    Connectivity, and Background Server, plus a top Notes block that
    promotes anomalies such as available updates, large rollout directories,
    optional MCP issues, and mixed auth signals.
    - Adds runtime provenance, install consistency, bundled/system search
    readiness, terminal/multiplexer metadata, `config.toml` parse status,
    auth mode details, sandbox details, feature flag summaries, update
    cache/latest-version state, app-server daemon state, SQLite integrity
    checks, rollout statistics, and provider-aware network diagnostics.
    - Adds ChatGPT WebSocket diagnostics that report the negotiated HTTP
    upgrade as `HTTP 101 Switching Protocols` and include timeout, DNS,
    auth, and provider context in detailed output.
    - Makes reachability provider-aware: API-key OpenAI setups check the API
    endpoint, ChatGPT auth checks the ChatGPT path, and custom/AWS/local
    providers check configured HTTP endpoints when available.
    - Adds structured, redacted JSON output where `checks` is keyed by check
    id and `details` is a key/value object for support tooling.
    - Integrates doctor with feedback uploads by attaching a best-effort
    `codex-doctor-report.json` report and adding derived Sentry tags for
    overall status and failing/warning checks.
    - Updates the TUI feedback consent copy so users can see that the doctor
    report is included when logs/diagnostics are uploaded.
    - Updates the CLI bug issue template to ask reporters for `codex doctor
    --json` and render pasted reports as JSON.
    
    ## Example Output
    
    The examples below are sanitized from local smoke runs with `--no-color`
    so the structure is reviewable in plain text.

    ## How to Test
    
    1. Run `cargo run --bin codex -- doctor --no-color`.
    2. Confirm the detailed report is the default and includes promoted
    Notes, grouped sections, terminal details, state DB integrity, rollout
    stats, provider reachability, WebSocket diagnostics, and app-server
    status.
    3. Run `cargo run --bin codex -- doctor --summary --no-color`.
    4. Confirm the compact view keeps the same sections and summary counts
    but omits detailed key/value rows.
    5. Run `cargo run --bin codex -- doctor --json`.
    6. Confirm the output is redacted JSON, `checks` is an object keyed by
    check id, and each check's `details` is a key/value object.
    7. Preview the CLI bug issue template and confirm the `Codex doctor
    report` field appears after the terminal field, asks for `codex doctor
    --json`, and renders pasted output as JSON.
    8. Start a feedback flow that includes logs.
    9. Confirm the upload consent copy lists `codex-doctor-report.json`
    alongside the log attachments.
    
    Targeted tests:
    
    - `cargo test -p codex-cli doctor`
    - `cargo test -p codex-app-server
    doctor_report_tags_summarize_status_counts`
    - `cargo test -p codex-feedback`
    - `cargo test -p codex-tui feedback_view`
    - `just argument-comment-lint`
    - `git diff --check`
  • [codex] Add response.processed websocket request (#21284)
    ## Summary
    
    - Add a `response.processed` websocket request payload and sender for
    Responses API websockets.
    - Send `response.processed` from `try_run_sampling_request` after a
    response completes, local turn processing succeeds, and the
    session-owned feature flag is enabled.
    - Add websocket coverage for both enabled and disabled feature-flag
    behavior.
    
    ## Validation
    
    - `just fmt`
    - `cargo test -p codex-core response_processed`
    - `cargo test -p codex-api responses_websocket`
    - `cargo test -p codex-features
    responses_websocket_response_processed_is_under_development`
    - `git diff --check`
    - `just fix -p codex-api -p codex-core -p codex-features`
    - `git diff --check origin/main...HEAD`
  • Bound websocket request sends with idle timeout (#20751)
    ## Why
    
    We saw Responses websocket sessions recover only after a long quiet
    period when the server had already logged the websocket as disconnected.
    The normal connect path is already bounded by
    `websocket_connect_timeout_ms`, but the first request send on an
    established websocket reused only the receive-side idle timeout after
    the write completed. If the socket write/pump stalls, the client can sit
    in `ws_stream.send(...)` without reaching the existing receive timeout.
  • [rollout-trace] Include x-request-id in rollout trace. (#20066)
    ## Why
    
    Rollout traces need an identifier that can be used to correlate a Codex
    inference with upstream Responses API, proxy, and engine logs. The
    reduced trace model already exposed `upstream_request_id`, but it was
    being populated from the Responses API `response.id`. That value is
    useful for `previous_response_id` chaining, but it is not the transport
    request id that upstream systems key on.
    
    This PR separates those concepts so trace consumers can reliably answer
    both questions:
    
    - which Responses API response did this inference produce?
    - which upstream request handled it?
    
    ## Structure
    
    The change keeps the upstream request id at the same lifecycle level as
    the provider stream:
    
    - `codex-api` captures the `x-request-id` HTTP response header when the
    SSE stream is created and exposes it on `ResponseStream`. Fixture and
    websocket streams set the field to `None` because they do not have that
    HTTP response header.
    - `codex-core` carries that stream-level id into `InferenceTraceAttempt`
    when recording terminal stream outcomes. Completed, failed, cancelled,
    dropped-stream, and pre-response error paths all record the id when it
    is available.
    - `rollout-trace` now records both identifiers in raw terminal inference
    events and response payloads: `response_id` for the Responses API
    `response.id`, and `upstream_request_id` for `x-request-id`.
    - The reducer stores both fields on `InferenceCall`. It also uses
    `response_id` for `previous_response_id` conversation linking, which
    removes the old accidental dependency on the misnamed
    `upstream_request_id` field.
    - Terminal inference reduction now consumes the full terminal payload
    (`InferenceCompleted`, `InferenceFailed`, or `InferenceCancelled`) in
    one place. That keeps status, partial payloads, response ids, and
    upstream request ids consistent across success, failure, cancellation,
    and late stream-mapper events.
    
    ## Why This Shape
    
    `x-request-id` is a property of the HTTP/provider response envelope, not
    an SSE event. Capturing it once in `codex-api` and plumbing it through
    terminal trace recording avoids trying to infer the value from stream
    contents, and it preserves the id even when the stream fails or is
    cancelled after only partial output.
    
    Keeping `response_id` separate from `upstream_request_id` also makes the
    reduced trace model less surprising: `response_id` remains the
    conversation-continuation id, while `upstream_request_id` is the
    operational correlation id for upstream debugging.
    
    ## Validation
    
    The PR updates trace and reducer coverage for:
    
    - reading `x-request-id` from SSE response headers;
    - storing the true upstream request id on completed inference calls;
    - preserving upstream request ids for cancelled and late-cancelled
    inference streams;
    - keeping `previous_response_id` reconstruction tied to `response_id`
    rather than transport request ids.
  • Add safety check notification and error handling (#19055)
    Adds a new app-server notification that fires when a user account has
    been flagged for potential safety reasons.
  • chore: document intentional await-holding cases (#18423)
    ## Why
    
    This PR prepares the stack to enable Clippy await-holding lints that
    were left disabled in #18178. The mechanical lock-scope cleanup is
    handled separately; this PR is the documentation/configuration layer for
    the remaining await-across-guard sites.
    
    Without explicit annotations, reviewers and future maintainers cannot
    tell whether an await-holding warning is a real concurrency smell or an
    intentional serialization boundary.
    
    ## What changed
    
    - Configures `clippy.toml` so `await_holding_invalid_type` also covers
    `tokio::sync::{MutexGuard,RwLockReadGuard,RwLockWriteGuard}`.
    - Adds targeted `#[expect(clippy::await_holding_invalid_type, reason =
    ...)]` annotations for intentional async guard lifetimes.
    - Documents the main categories of intentional cases: active-turn state
    transitions that must remain atomic, session-owned MCP manager accesses,
    remote-control websocket serialization, JS REPL kernel/process
    serialization, OAuth persistence, external bearer token refresh
    serialization, and tests that intentionally serialize shared global or
    session-owned state.
    - For external bearer token refresh, documents the existing
    serialization boundary: holding `cached_token` across the provider
    command prevents concurrent cache misses from starting duplicate refresh
    commands, and the current behavior is small enough that an explicit
    expectation is easier to maintain than adding another synchronization
    primitive.
    
    ## Verification
    
    - `cargo clippy -p codex-login --all-targets`
    - `cargo clippy -p codex-connectors --all-targets`
    - `cargo clippy -p codex-core --all-targets`
    - The follow-up PR #18698 enables `await_holding_invalid_type` and
    `await_holding_lock` as workspace `deny` lints, so any undocumented
    remaining offender will fail Clippy.

  • feat: add opt-in provider runtime abstraction (#17713)
    ## Summary
    
    - Add `codex-model-provider` as the runtime home for model-provider
    behavior that does not belong in `codex-core`, `codex-login`, or
    `codex-api`.
    - The new crate wraps configured `ModelProviderInfo` in a
    `ModelProvider` trait object that can resolve the API provider config,
    provider-scoped auth manager, and request auth provider for each call.
    - This centralizes provider auth behavior in one place today, and gives
    us an extension point for future provider-specific auth, model listing,
    request setup, and related runtime behavior.
    
    ## Tests
    Ran tests manually to make sure that provider auth under different
    configs still work as expected.

      ###### Summary
      - Add client-visible 401 diagnostics for auth attachment, upstream auth classification, and 401 request id / cf-ray correlation.
      - Record unauthorized recovery mode, phase, outcome, and retry/follow-up status without changing auth behavior.
      - Surface the highest-signal auth and recovery fields on uploaded client bug reports so they are usable in Sentry.
      - Preserve original unauthorized evidence under `auth_401_*` while keeping follow-up result tags separate.
    
      ###### Rationale (from spec findings)
      - The dominant bucket needed proof of whether the client attached auth before send or upstream still classified the request as missing auth.
      - Client uploads needed to show whether unauthorized recovery ran and what the client tried next.
      - Request id and cf-ray needed to be preserved on the unauthorized response so server-side correlation is immediate.
      - The bug-report path needed the same auth evidence as the request telemetry path, otherwise the observability would not be operationally useful.
    
      ###### Scope
      - Add auth 401 and unauthorized-recovery observability in `codex-rs/core`, `codex-rs/codex-api`, and `codex-rs/otel`, including feedback-tag surfacing.
      - Keep auth semantics, refresh behavior, retry behavior, endpoint classification, and geo-denial follow-up work out of this PR.
    
      ###### Trade-offs
      - This exports only safe auth evidence: header presence/name, upstream auth classification, request ids, and recovery state. It does not export token values or raw upstream bodies.
      - This keeps websocket connection reuse as a transport clue because it can help distinguish stale reused sessions from fresh reconnects.
      - Misroute/base-url classification and geo-denial are intentionally deferred to a separate follow-up PR so this review stays focused on the dominant auth 401 bucket.
    
      ###### Client follow-up
      - PR 2 will add misroute/provider and geo-denial observability plus the matching feedback-tag surfacing.
      - A separate host/app-server PR should log auth-decision inputs so pre-send host auth state can be correlated with client request evidence.
      - `device_id` remains intentionally separate until there is a safe existing source on the feedback upload path.

  • feat(app-server, core): add more spans (#14479)
    ## Description
    
    This PR expands tracing coverage across app-server thread startup, core
    session initialization, and the Responses transport layer. It also gives
    core dispatch spans stable operation-specific names so traces are easier
    to follow than the old generic `submission_dispatch` spans.
    
    Also use `fmt::Display` for types that we serialize in traces so we send
    strings instead of rust types
  • client: extend custom CA handling across HTTPS and websocket clients (#14239)
    ## Stacked PRs
    
    This work is now effectively split across two steps:
    
    - #14178: add custom CA support for browser and device-code login flows,
    docs, and hermetic subprocess tests
    - #14239: extend that shared custom CA handling across Codex HTTPS
    clients and secure websocket TLS
    
    Note: #14240 was merged into this branch while it was stacked on top of
    this PR. This PR now subsumes that websocket follow-up and should be
    treated as the combined change.
    
    Builds on top of #14178.
    
    ## Problem
    
    Custom CA support landed first in the login path, but the real
    requirement is broader. Codex constructs outbound TLS clients in
    multiple places, and both HTTPS and secure websocket paths can fail
    behind enterprise TLS interception if they do not honor
    `CODEX_CA_CERTIFICATE` or `SSL_CERT_FILE` consistently.
    
    This PR broadens the shared custom-CA logic beyond login and applies the
    same policy to websocket TLS, so the enterprise-proxy story is no longer
    split between “HTTPS works” and “websockets still fail”.
    
    ## What This Delivers
    
    Custom CA support is no longer limited to login. Codex outbound HTTPS
    clients and secure websocket connections can now honor the same
    `CODEX_CA_CERTIFICATE` / `SSL_CERT_FILE` configuration, so enterprise
    proxy/intercept setups work more consistently end-to-end.
    
    For users and operators, nothing new needs to be configured beyond the
    same CA env vars introduced in #14178. The change is that more of Codex
    now respects them, including websocket-backed flows that were previously
    still using default trust roots.
    
    I also manually validated the proxy path locally with mitmproxy using:
    `CODEX_CA_CERTIFICATE=~/.mitmproxy/mitmproxy-ca-cert.pem
    HTTPS_PROXY=http://127.0.0.1:8080 just codex`
    with mitmproxy installed via `brew install mitmproxy` and configured as
    the macOS system proxy.
    
    ## Mental model
    
    `codex-client` is now the owner of shared custom-CA policy for outbound
    TLS client construction. Reqwest callers start from the builder
    configuration they already need, then pass that builder through
    `build_reqwest_client_with_custom_ca(...)`. Websocket callers ask the
    same module for a rustls client config when a custom CA bundle is
    configured.
    
    The env precedence is the same everywhere:
    - `CODEX_CA_CERTIFICATE` wins
    - otherwise fall back to `SSL_CERT_FILE`
    - otherwise use system roots
    
    The helper is intentionally narrow. It loads every usable certificate
    from the configured PEM bundle into the appropriate root store and
    returns either a configured transport or a typed error that explains
    what went wrong.
    
    ## Non-goals
    
    This does not add handshake-level integration tests against a live TLS
    endpoint. It does not validate that the configured bundle forms a
    meaningful certificate chain. It also does not try to force every
    transport in the repo through one abstraction; it extends the shared CA
    policy across the reqwest and websocket paths that actually needed it.
    
    ## Tradeoffs
    
    The main tradeoff is centralizing CA behavior in `codex-client` while
    still leaving adoption up to call sites. That keeps the implementation
    additive and reviewable, but it means the rule "outbound Codex TLS that
    should honor enterprise roots must use the shared helper" is still
    partly enforced socially rather than by types.
    
    For websockets, the shared helper only builds an explicit rustls config
    when a custom CA bundle is configured. When no override env var is set,
    websocket callers still use their ordinary default connector path.
    
    ## Architecture
    
    `codex-client::custom_ca` now owns CA bundle selection, PEM
    normalization, mixed-section parsing, certificate extraction, typed
    CA-loading errors, and optional rustls client-config construction for
    websocket TLS.
    
    The affected consumers now call into that shared helper directly rather
    than carrying login-local CA behavior:
    - backend-client
    - cloud-tasks
    - RMCP client paths that use `reqwest`
    - TUI voice HTTP paths
    - `codex-core` default reqwest client construction
    - `codex-api` websocket clients for both responses and realtime
    websocket connections
    
    The subprocess CA probe, env-sensitive integration tests, and shared PEM
    fixtures also live in `codex-client`, which is now the actual owner of
    the behavior they exercise.
    
    ## Observability
    
    The shared CA path logs:
    - which environment variable selected the bundle
    - which path was loaded
    - how many certificates were accepted
    - when `TRUSTED CERTIFICATE` labels were normalized
    - when CRLs were ignored
    - where client construction failed
    
    Returned errors remain user-facing and include the relevant env var,
    path, and remediation hint. That same error model now applies whether
    the failure surfaced while building a reqwest client or websocket TLS
    configuration.
    
    ## Tests
    
    Pure unit tests in `codex-client` cover env precedence and PEM
    normalization behavior. Real client construction remains in subprocess
    tests so the suite can control process env and avoid the macOS seatbelt
    panic path that motivated the hermetic test split.
    
    The subprocess coverage verifies:
    - `CODEX_CA_CERTIFICATE` precedence over `SSL_CERT_FILE`
    - fallback to `SSL_CERT_FILE`
    - single-cert and multi-cert bundles
    - malformed and empty-file errors
    - OpenSSL `TRUSTED CERTIFICATE` handling
    - CRL tolerance for well-formed CRL sections
    
    The websocket side is covered by the existing `codex-api` / `codex-core`
    websocket test suites plus the manual mitmproxy validation above.

  • Stabilize websocket response.failed error delivery (#14017)
    ## What changed
    - Drop failed websocket connections immediately after a terminal stream
    error instead of awaiting a graceful close handshake before forwarding
    the error to the caller.
    - Keep the success path and the closed-connection guard behavior
    unchanged.
    
    ## Why this fixes the flake
    - The failing integration test waits for the second websocket stream to
    surface the model error before issuing a follow-up request.
    - On slower runners, the old error path awaited
    `ws_stream.close().await` before sending the error downstream. If that
    close handshake stalled, the test kept waiting for an error that had
    already happened server-side and nextest timed it out.
    - Dropping the failed websocket immediately makes the terminal error
    observable right away and marks the session closed so the next request
    reconnects cleanly instead of depending on a best-effort close
    handshake.
    
    ## Code or test?
    - This is a production logic fix in `codex-api`. The existing websocket
    integration test already exercises the regression path.
  • Handle websocket timeout (#12791)
    Sometimes websockets will timeout with 400 error, ensure we retry it.
  • Reuse connection between turns (#12294)
    Add a pool of one to the model client to reuse connections across turns.
  • add(core): safety check downgrade warning (#11964)
    Add per-turn notice when a request is downgraded to a fallback model due
    to cyber safety checks.
    
    **Changes**
    
    - codex-api: Emit a ServerModel event based on the openai-model response
    header and/or response payload (SSE + WebSocket), including when the
    model changes mid-stream.
    - core: When the server-reported model differs from the requested model,
    emit a single per-turn warning explaining the reroute to gpt-5.2 and
    directing users to Trusted
        Access verification and the cyber safety explainer.
    - app-server (v2): Surface these cyber model-routing warnings as
    synthetic userMessage items with text prefixed by Warning: (and document
    this behavior).
  • Pump pings (#11413)
    Keep processing ping even when the agent isn't actively running.
    
    Otherwise the connection will drop.
  • Do not attempt to append after response.completed (#11402)
    Completed responses are fully done, and new response must be created.
  • chore: put crypto provider logic in a shared crate (#11294)
    Ensures a process-wide rustls crypto provider is installed.
    
    Both the `codex-network-proxy` and `codex-api` crates need this.
  • Translate websocket errors (#10937)
    When getting errors over a websocket connection, translate the error
    into our regular API error format
  • feat: enable premessage-deflate for websockets (#10966)

  • Add a codex.rate_limits event for websockets (#10324)
    When communicating over websockets, we can't rely on headers to deliver
    rate limit information. This PR adds a `codex.rate_limits` event that
    the server can pass to the client to inform them about rate limit usage.
    The client parses this data the same way we parse rate limit headers in
    HTTP mode.
    
    This PR also wires up the etag and reasoning headers for websockets
