## Why
The user-verification API previously returned an unsupported provider on macOS. Enable native verification using biometric-protected credentials.
## What changed
- Implement credential status, creation, reuse, deletion, and challenge signing with P-256 Secure Enclave keys in the Data Protection Keychain.
- Require biometric authentication through the key's access-control policy and use a fresh `LAContext` for each signature.
- Report Touch ID hardware support independently of enrollment and current readiness, and map native failures to structured verification errors.
- Serialize credential operations across processes with cancellable file-lock waits. Invalidate pending authentication on cancellation and wait for the signer to exit before releasing the lock.
## Testing
Add unit tests for lock contention and cancellation, authentication teardown and late-result rejection, native error classification, and validation of Secure Enclave key attributes.
GitOrigin-RevId: 93268962cd824b2befc1a0c54b99dcb77a0f1044
## Why
The voice host drained incoming RTP packets without playing them. Route received audio through decoding and speaker output while preserving speaker suppression boundaries.
## What changed
- Add a GStreamer pipeline with RTP jitter buffering, Opus decoding, conversion, and resampling into the native speaker sink.
- Rebuild playout when the speaker is re-enabled, reject packets received before the new pipeline started, and discard queued audio and echo references on speaker transitions while preserving capture history.
- Limit each receive pass to 64 packets so incoming media cannot indefinitely delay audio controls.
- Prevent retired sink failures from failing a new speaker generation, and retain the last coherent playback delay estimate during callback contention.
## Testing
Add tests for real Opus playback and stale packet rejection, combined microphone mute and speaker suppression, retired sink failures, delay contention, and echo-reference reset without losing capture history.
GitOrigin-RevId: c91c94a2ba2347ac98af4e7fd1dc331ae766cc45
## What changed
- Add a `GstAudioSink` subclass backed by a bounded mono `F32LE` playback writer, with partial writes, cancellation on speaker epoch changes, and delay accounting for queued samples and pending device output.
- Recreate the CPAL output stream and discard buffered audio when speaker controls change the epoch, preventing stale audio from surviving suppression.
- Add GStreamer dependencies, adjust Windows Bazel native-tool selection, and allow the helper handshake time to load startup-linked libraries.
- Separate installed-client tests from protocol lifecycle tests and supply native startup libraries in test packages.
## Testing
Add unit coverage for partial writes, sample accounting, suppression cancellation, stale writers, device delay, invalid samples, and stalled consumption.
GitOrigin-RevId: c48c48d2fee00659cf6f8a4039a6745385cb77cd
## What changed
- Add explicit x64 and ARM64 targets for native builds, runtime preparation, and linking using the existing voice recipes. Each target requires native Windows execution of the matching architecture.
- Declare compiler, SDK, Python, and CMake inputs; require an explicitly supplied Cygwin/pkgconf tool tree and a fixed `SystemRoot`. Validate installed tool selections against the manifest and declared files.
- Pair Windows DLLs with SDK import libraries, preserve plugin and receipt runfiles, and omit Unix runtime-search flags. Use Python for portable payload copying.
- Correct the MSVC ARM64 tool directory casing to `HostArm64` and document provisioning and build commands.
The generic Rust-consumer aliases remain separate; native Windows Bazel execution and consumer validation are still needed to establish complete Windows voice support.
## Testing
Add eight unit tests covering tool selection, path anchoring, invalid inputs, and DLL/import-library copying, plus x64 and ARM64 link smoke targets that reference `gst_version`.
GitOrigin-RevId: fb2b4998e9ffb5b64ca830ebf4bb4633fc959eb9
## Why
The MSVC runtime and Windows SDK repositories discard their tool binaries during setup, leaving native build tools unavailable to Bazel consumers.
## What changed
Patch `windows_support` to retain native MSVC tools and support files, plus the selected SDK's versioned tools, for `x64` and `arm64`. Expose them through opt-in `msvc_tools_x64`, `msvc_tools_arm64`, `winsdk_tools_x64`, and `winsdk_tools_arm64` directory targets.
Exclude the retained tool trees from the existing `sysroot_files`, `headers`, and `libs` targets.
GitOrigin-RevId: df7db08fecfb5e389252332842b8d7361d166891
## Why
Native voice builds ignore ambient compiler flags, but need a way to accept declared compiler, linker, and archive-tool inputs.
## What changed
- Add repeated `--c-flag`, `--cxx-flag`, and `--link-flag` options plus optional `--ar` and `--ranlib` paths for Unix builds. Record flags and pass them through CMake, Meson, and libffi, including Objective-C flags on macOS.
- Preserve literal libffi compiler arguments with response files. Reject flags containing whitespace, libffi paths requiring shell quoting, and Unix toolchain overrides on Windows.
- Add a pinned Bazel `pkg-config` tool built with LLVM archive tools and native macOS configure checks. Register the pinned Make toolchain and patch its bootstrap to pass preprocessor flags and enable cross-compilation configuration.
## Testing
Extend native-build tests to verify compiler and linker flags, explicit archive tools, Meson and Objective-C inputs, literal definitions through shell and recursive Make expansion, and rejection of unsupported overrides.
GitOrigin-RevId: e5ea541ec76abfa170f6b0411b0f14cd698c07e7
## Why
`voice-host` previously drained captured audio locally without sending it to the peer. Connect capture to the outgoing media track while preserving mute boundaries and limiting stale audio.
## What changed
- Resample capture and render references to 48 kHz with Rubato, apply Sonora echo cancellation, noise suppression, and gain control, and encode capture as 20 ms mono Opus packets.
- Attach an Opus track to the WebRTC peer and advance RTP timestamps across mute gaps without introducing sequence-number gaps.
- Prioritize queued controls and shutdown between sends. Clear pending audio and processing history on microphone mute transitions, reject delayed pre-unmute buffers, and reset partial history after capture gaps.
- Size bounded capture and render queues for device rates, validate callback timing, enforce a 500 ms processing deadline, and time out stalled sends after 100 ms.
Receive/decode and TUI integration remain unimplemented. The bundled Opus encoder build requires CMake and a C compiler.
## Testing
Add synthetic-audio tests for Opus decoding at 44.1 and 48 kHz input rates, echo reduction, capture gaps, stale audio, queue capacity, and control priority. A loopback WebRTC test verifies RTP delivery, decoded signal, mute isolation, and timestamp and sequence continuity across mute gaps.
GitOrigin-RevId: 38b8438577cfadb8124f8aeb426dffbab4845964
## Why
The bundled Opus encoder uses CMake and should not depend on tools available on a build worker's `PATH`.
## What changed
- Add `rules_foreign_cc` and provide its pinned CMake and Ninja tools and data to the `opusic-sys` build script.
- Add a CMake toolchain file that selects the declared Ninja executable, resolves the archiver path, and sets the target system and processor from `TARGET`, while retaining Bazel's compiler, SDK, and linker inputs.
GitOrigin-RevId: 48580c506d088d8c76cce958589ff94da458bd79
## What changed
- Add `openDevices` and `setAudioControls` to the helper protocol. Open the default microphone and speaker after runtime initialization and transport negotiation, initially muted and suppressed.
- Use CPAL on macOS, GNU Linux, and MSVC Windows, with native audio dependencies confined to `codex-voice-host`. Add ALSA development dependencies to Linux CI.
- Pack callback samples into preallocated, bounded queues and service devices every 5 ms. Reject incompatible callback configurations, invalidate queued audio on control transitions, and reject capture backlog after unmute using device timestamps.
- Handle recoverable stream underruns and overruns without terminating the helper; terminate on device failure, active audio queue overflow, or stale queued audio.
Device opening only establishes local device readiness. Capture and rendered audio references are drained locally; encoding, decoding, and peer audio are not connected by this change.
## Testing
Add unit tests for mute boundaries, stale playback invalidation, sample bounds, partial-block packing and timestamps, callback size and timing limits, startup silence, queue overflow, and recoverable stream errors.
GitOrigin-RevId: 108aea3d411ef6c12908fe5fb67aaf9cddf4475f
## What changed
- Configure the CLI and app server to use `tikv-jemallocator` on
`x86_64-unknown-linux-musl` and `aarch64-unknown-linux-musl`.
- Keep the dependency and global allocator selection scoped to those targets.
GitOrigin-RevId: 93c54c90d9acb7e48edffd032cd8ec685a782210
## What changed
- Add rendered HTML alongside the original Markdown when copying a whole response through the native clipboard, so rich-text destinations preserve headings, lists, tables, code, and other formatting.
- Keep code-block, blockquote, transcript, terminal, and WSL clipboard copies as plain text.
- Escape raw HTML, omit remote image sources, and render unsupported link destinations as visible text when producing clipboard HTML.
## Testing
- Add coverage for rich formatting, local and unsafe links, inert images, fenced tables, copy selection formats, and clipboard fallbacks.
GitOrigin-RevId: c6f5edd88b65f9e9b1ddc5618442868cf47ee560
## What changed
- Add helper protocol requests to create a WebRTC offer, apply an answer, and report readiness once the ordered `oai-events` data channel opens.
- Support UDP and TCP candidates while bounding signaling size, remote candidates, inbound TCP streams, and WebRTC buffers. Redact session descriptions and peer errors from diagnostics.
- Close unexpected remote data channels and tear down the peer during helper shutdown, including when the parent pipe is lost during startup.
## Testing
- Exercise offer/answer negotiation and clean shutdown over real UDP and TCP sockets.
- Cover signaling validation, candidate and connection limits, early packet loss, slow TCP connection setup, and blocked-startup parent loss.
GitOrigin-RevId: 5f5e60a3a4d1d8eaca2e4724e66284f54061b6af
## What changed
- Upgrade `rmcp` and `rmcp-macros` from 3.1.3 to 3.2.0.
- Refresh the Cargo and Bazel lockfiles for the new versions.
GitOrigin-RevId: a1d7696eafe6a150c6e09c3cc9c3663a8fd68679
## What changed
- Probe whether the native Windows MXC process security environment is usable
when selecting a sandbox.
- Emit `codex.windows_mxc.available` at most once per process, labeled with the
probe result.
- Add the MXC workspace dependencies for Cargo and Bazel, and pin
`tracelogging` to a version compatible with the GNU Windows toolchain.
GitOrigin-RevId: d7cfeed6f0333feda5764e1ee44fe5bbd50f9a58
## What changed
- Upgrade `rmcp` and `rmcp-macros` from 3.1.2 to 3.1.3.
- Preserve authentication-required and retryable transport classifications when modern MCP discovery falls back to legacy initialization.
- Prevent unrelated discovery errors from triggering legacy fallback while retaining their diagnostics.
## Testing
- Cover authentication challenges and transient initialization failures during legacy fallback.
- Verify that a failed OAuth issuer check does not consume the pending authorization state.
GitOrigin-RevId: 957c0873fec1148883dd163fbaeb77d7593d8c53
## What changed
- Add a Tree-sitter-based lowerer that converts a conservative subset of literal PowerShell commands into argument vectors.
- Reject dynamic expressions, parse recovery, unsupported value conversions, directives, and source outside recognized command nodes instead of guessing their meaning.
- Keep the lowerer alongside the existing production parser for later adoption.
## Testing
- Add fixture-driven coverage for supported literal commands and unsupported or ambiguous syntax, including a dedicated `#requires` rejection test.
GitOrigin-RevId: a6e7acc264ca40df264db4b271e38ae7d89e1ec4
## Why
App widgets need to read resources using the app and account context of the
tool call that produced them, including after a thread is restored.
## What changed
- Add an optional `originCallId` to `mcpServer/resource/read` requests and
return it on successful scoped reads.
- Track bounded provenance for successful app tool calls in thread history and
use the current tool binding, account link, and app policy when reading the
associated widget resource.
- Reject missing, mismatched, failed, or ambiguous origins, while keeping
app-only tools available for widget reads without exposing them to the model.
## Testing
Add app-server coverage for scoped widget reads across both history modes,
ephemeral and persistent threads, server restarts, app-only visibility, and
invalid origin cases.
GitOrigin-RevId: 11eaefc066b2a3b639599e4cbdef680233d150a2
## What changed
- Upgrade `rmcp` from 3.0.0 to 3.1.2.
- Use `rmcp`'s native JSON-RPC decoding and remove the local compatibility layer for multi-round-trip tool results.
- Preserve response metadata on `input_required` SSE results.
- Support OAuth protected-resource metadata discovery and include the discovered resource audience when refreshing tokens.
## Testing
- Add coverage for metadata preservation on modern SSE `input_required` responses.
- Add an OAuth startup scenario that discovers protected-resource metadata and verifies the refresh-token resource audience.
GitOrigin-RevId: 689f009b4a33552b640304111b74585b4009eeb8
## Why
Terminal probes and other bootstrap work can leave keys or partial control
sequences buffered before an interactive startup screen is visible. Those
inputs must not accidentally select or confirm an action, while typeahead
intended for the composer should survive terminal initialization.
## What changed
- Replay user input consumed by Unix startup probes through Crossterm while
filtering completed terminal color replies, and avoid consuming the Windows
console input queue when detecting default colors.
- Drain decoded and unread input after rendering actionable startup screens,
including onboarding trust, migration, update, provider, resume, and hooks
prompts. Keep incomplete control sequences quarantined and fail closed when
an input boundary cannot be resolved.
- Restore terminal modes if initialization exits early and bound terminal probe
reads by time and byte limits.
## Testing
Add parser, boundary, onboarding, and PTY coverage for preserved typeahead,
split escape sequences, bracketed paste, delayed input, and fresh input after
an interactive screen becomes ready.
GitOrigin-RevId: 321198996cdd88fe9b43c4a762e750bff450482c
## What changed
- Update the workspace `lru` requirement to `0.18.2`, consolidating consumers on a single version.
- Raise the `webbrowser` requirement to `1.2.2` and refresh the Cargo and Bazel lockfiles.
GitOrigin-RevId: c70dce42f4b6e0dc5567a28f778fd12c720d8f4c
## What changed
- Add pinned `windows_support` repositories for the Windows SDK and MSVC runtime on `x64` and `arm64`.
- Require explicit acceptance through `--repo_env=BAZEL_MSVC_RUNTIME_VISUAL_STUDIO_EULA=1` before materializing the MSVC runtime.
- Preserve case-only SDK aliases when repositories created on case-insensitive Windows filesystems are consumed by case-sensitive remote executors.
GitOrigin-RevId: c7a5278e87c5e7e25e9c5f60af3d99e19303b0fd
## What changed
- Add the `codex.code_mode.v1` protobuf API for managing code-mode sessions, executions, waits, tool callbacks, notifications, and content results.
- Generate and export the Rust client/server bindings with `tonic` under Cargo.
- Add Bazel protobuf targets and a `prost` toolchain that uses the workspace's Rust runtime versions.
GitOrigin-RevId: 51d9d044e01dab2f4d25ab79aa7a52585485eee3
## What changed
- Update the Rust MCP SDK from `3.0.0-beta.3` to `3.0.0` and adapt to its renamed metadata and server discovery types.
- Accept discovery responses without server identity metadata, using the configured server name as a fallback, and rely on the SDK's native support for namespaced server identity metadata.
- Preserve typed OAuth HTTP errors so transport failures, cross-origin redirects, and transient HTTP responses are reported instead of being treated as anonymous access.
## Testing
- Cover modern discovery with namespaced or missing server identity over HTTP, SSE, and stdio.
- Cover OAuth discovery error propagation for transport failures, redirects, and transient status codes.
GitOrigin-RevId: 12c1e45136cca89ce4fb15986c2b5df14608682a
## What changed
- Upgrade `ratatui`, `ratatui-macros`, `crossterm`, and `ansi-to-tui`, and adapt the TUI to their updated rendering, backend, color-conversion, and cell APIs.
- Use Ratatui's cell-width and continuation-cell metadata when mapping OSC 8 hyperlinks so links remain aligned across wrapped wide glyphs and halfwidth characters with dakuten.
- Preserve explicit hyperlinks in the sign-in success screen and empty MCP state without embedding escape sequences in the text passed to Ratatui.
## Testing
- Add regression coverage for hyperlink placement across wide glyphs and halfwidth dakuten, hyperlink preservation in onboarding and MCP output, and display-width handling.
GitOrigin-RevId: 8460873e5a266923acd0417bc46264845eab0134
## What changed
- Upgrade the Rust `v8` crate to `150.4.0` and the Bazel V8 source to
`15.0.245.2`.
- Refresh the prebuilt archives, checksums, LLVM source revisions, Bazel targets,
and downstream V8 patches for the new release.
- Expose the pinned llvm-libc headers under V8's expected include path for
source builds.
GitOrigin-RevId: 91c953b2fb707b221fdd772f9ca88fb71606f70f
## What changed
- Require callers to provide an HTTP client for MCP OAuth discovery and login, removing the separate direct `reqwest` path.
- Use the shared `http` and `url` types throughout the MCP client and drop its direct `reqwest` dependency.
- Preserve configured MCP headers when routing OAuth discovery through the provided client.
## Testing
- Add coverage that routed OAuth discovery forwards configured headers.
GitOrigin-RevId: 1345f56bd794626533133447597a5908e57b9b48
## What changed
- Update the `rmcp` model and transport integrations for `3.0.0-beta.3`.
- Preserve legacy `elicitation/create` form requests, schema defaults, metadata, and wire-format compatibility while adopting the new elicitation types.
- Harden OAuth discovery by using GET-first discovery without starting an MCP session, preventing cross-origin header redirects, validating authorization-server and callback issuers, and retaining compatibility with metadata that omits an issuer.
- Keep stored OAuth credentials readable and avoid requiring reauthorization after transient refresh failures.
## Testing
- Add coverage for legacy elicitation round trips, OAuth discovery variants, callback issuer validation, credential migration, and refresh failures.
GitOrigin-RevId: 756197d26f3fd347c28c400228f6b3d06ed493b7
## What changed
- Update the `crossterm` Cargo patch to use the OpenAI OSS fork while retaining the existing revision.
- Refresh the Cargo and Bazel lockfiles and the `cargo-deny` Git-source allowlist for the new repository URL.
GitOrigin-RevId: 96c70abca95b9c5c8f19d1bc2d30976c5797ba8c
## What changed
- Upgrade `rules_rs` from `0.0.58` to `0.0.96` and LLVM from `0.7.9` to
`0.8.11`, updating extension paths, platform constraints, and compatibility
patches for the current APIs.
- Add native `windows-gnullvm` execution support for the argument-comment lint
toolchain while retaining MSVC execution for existing cross-target builds.
- Build `aws-lc-sys` through the Bazel Central Registry `aws-lc` module and
`rules_rs` integration, removing the replaced crate-specific patches.
GitOrigin-RevId: 9829bcdb6ac74e846b713568aac38ea2fa3c42a2
## Why
Audio attachments could be dropped from tool outputs and reconstructed thread history, while inline base64 payload size could overstate their model context cost.
## What changed
- Preserve remote and local audio attachments in legacy user-message events and thread history.
- Keep audio from function and custom tool outputs when the model supports it and the output fits the truncation budget; otherwise replace it with an omission marker.
- Estimate inline audio cost from its duration, with a serialized-size fallback for malformed or unsupported data URLs, so compaction and truncation use model-visible cost instead of raw base64 size.
- Replace audio in messages and tool outputs with an explanatory placeholder for models without audio input support.
## Testing
Add coverage for history round trips, dynamic tool responses, modality filtering, duration-based context estimates, output-budget truncation, and remote compaction.
GitOrigin-RevId: 5ed4628850a668f8383b7cd73db71b144cc02cd1
## What changed
- Add the experimental `thread/searchOccurrences` app-server method for case-insensitive literal search across visible user messages and final assistant messages without replaying the thread.
- Return paginated snippets with UTF-16 match ranges and `thread/turns/list` cursors for navigating to each matching turn.
- Index persisted item types to efficiently select searchable messages from paginated thread history.
## Testing
- Add an app-server integration test covering pagination, steering messages, final-answer selection, Markdown normalization, and UTF-16 offsets.
GitOrigin-RevId: e80160e0f83eb4e5db8de862307085093bee362b
## Why
Selecting a usage-limit reset from the picker immediately started redemption,
leaving no opportunity to verify the choice.
## What changed
- Open a separate confirmation popup before redeeming a selected reset, with
`No, go back` selected by default.
- Show backend-provided reset titles and descriptions in the picker and
confirmation, with generic fallback copy when those details are absent.
- Ignore duplicate or stale confirmation and redemption events, while retaining
the idempotency key needed to retry a failed redemption.
## Testing
- Added coverage for confirmation, cancellation, backend copy, duplicate and
stale events, successful redemption, and retry behavior.
GitOrigin-RevId: 828945f99f06e8c73941fd864e4aa9ac52729f98
## What changed
- Remove `codex-realtime-webrtc` from the Cargo workspace and Bazel build,
along with its native WebRTC dependency graph.
- Use `blake3`'s pure Rust implementation on
`x86_64-pc-windows-gnullvm`, where the Bazel lint toolchain cannot
reliably materialize the crate's native x86 assembly archives.
GitOrigin-RevId: c382d888cd7ada7a17a7a0dcbdecbe00744f5055
## What changed
- Delete the `codex-execpolicy-legacy` crate, its default policy, and its tests.
- Remove the crate from the Cargo and Bazel workspaces and clean up its unused dependencies.
- Remove the legacy matcher reference from the current exec policy documentation.
GitOrigin-RevId: ee756958b46bf759ad43dec8aa1379c1cd4d8b0d
## Why
The `cargo-deny` job on `main` began failing after
[RUSTSEC-2026-0194](https://rustsec.org/advisories/RUSTSEC-2026-0194)
and
[RUSTSEC-2026-0195](https://rustsec.org/advisories/RUSTSEC-2026-0195)
flagged the workspace `quick-xml 0.38.4`. Both denial-of-service issues
are fixed in `quick-xml 0.41.0`.
A `quick-xml 0.39.4` copy must temporarily remain because the latest
`plist` and `wayland-scanner` releases have not adopted 0.41 yet.
Neither retained path accepts attacker-controlled XML at runtime:
`plist` does not exercise the affected APIs, and `wayland-scanner`
parses trusted protocol definitions at build time. Compatible upstream
bumps are already open in
[rust-plist#191](https://github.com/ebarnard/rust-plist/pull/191) and
[wayland-rs#938](https://github.com/Smithay/wayland-rs/pull/938).
## What changed
- Upgrade the workspace `quick-xml` dependency used by `codex-protocol`
to 0.41.0.
- Refresh `Cargo.lock` and `MODULE.bazel.lock`; this also updates
`plist` to 1.9.0 and `wayland-scanner` to 0.31.10.
- Add synchronized, temporary `cargo-deny` and `cargo-audit` exceptions
for the trusted `quick-xml 0.39.4` paths, with both upstream releases
recorded as the removal condition.
## Testing
- `cargo deny check`
- `just test -p codex-protocol` (238 tests)
- `just bazel-lock-check`
## Summary
- Update `rmcp` and `rmcp-macros` from 1.7.0 to 1.8.0.
- Adapt to the new shared `peer_info` return type.
- Box OAuth status discovery at the MCP boundary to keep the expanded
future type from overflowing Rust's trait recursion limit.
This brings in custom OAuth HTTP client support from
[modelcontextprotocol/rust-sdk#908](https://github.com/modelcontextprotocol/rust-sdk/pull/908).
## Summary
- upgrade the bundled OpenSSL source from 3.5.5 to 3.6.3
- update the Bazel `openssl-sys` build dependency to use the upgraded
source crate
- refresh the Bazel module lockfile
## Why
OpenSSL 3.5.5 is within the affected ranges for security issues fixed in
later releases. The Rust `openssl-src` wrapper does not currently
publish OpenSSL 3.5.7, so this moves the vendored Linux musl build to
the available patched 3.6.3 release.
## Why
`openai-oss-forks/tokio-tungstenite` now includes the updated
`tungstenite` fork revision from
[openai-oss-forks/tokio-tungstenite#3](https://github.com/openai-oss-forks/tokio-tungstenite/pull/3).
Codex should consume the merged fork commit and resolve its direct and
transitive `tungstenite` dependencies to the same revision instead of
retaining the older pins.
## What Changed
- Advanced the `tokio-tungstenite` git pin to
`0e5b2d73aa18dd9f0a50ee9ff199d5aef7594186`.
- Advanced the `tungstenite` fork pin to
`4fffad30fe373adbdcffab9545e9e9bf4f2fc19f` and adjusted the patch source
so the transitive dependency resolves to that revision.
- Updated `Cargo.lock` and `MODULE.bazel.lock` to match the dependency
graph.
The custom Windows argument-comment-lint job was temporarily moved to
`windows-2022` in #28940 after hermetic LLVM source extraction failed on
the newer runner. This takes the upstream extraction fix so the job can
return to the intended custom runner.
This upgrades `llvm` to `0.7.9` and `rules_cc` to `0.2.18`, refreshes
the module lock, rebases the remaining Windows and custom libc++
patches, drops the obsolete symlink-extraction workaround, and restores
the `windows-x64` runner configuration.
Validation:
- Verified all LLVM patches apply cleanly against the `0.7.9` source.
- Built `@llvm-project//compiler-rt:clang_rt.builtins.static`.
## Why
Responses websocket connections use `tokio-tungstenite`. When DNS
returns an unusable native IPv6 address before a working IPv4 address,
sequential dialing can consume Codex's outer websocket timeout before
reaching IPv4. The merged fork change adds Happy Eyeballs-style
alternate-family racing so websocket dialing matches the recovery
behavior already present in the HTTP path.
## What Changed
Advance the workspace `tokio-tungstenite` patch from `132f5b39` to
merged commit `e5e64b86`, and update the matching lockfile source. The
new revision comes from
[openai-oss-forks/tokio-tungstenite#1](https://github.com/openai-oss-forks/tokio-tungstenite/pull/1).
## Why
Rendezvous forwards traffic between the orchestrator and exec-server.
The endpoints need to authenticate each other and encrypt that traffic
without trusting Rendezvous with plaintext or endpoint keys.
## Changes
- Adds a hybrid Noise IK channel through Clatter using X25519,
ML-KEM-768, AES-256-GCM, and SHA-256.
- Binds each handshake to `environment_id`, `executor_registration_id`,
and `stream_id`.
- Pins the registry-provided executor key and carries the harness
authorization inside the encrypted handshake.
- Orders relay frames before consuming Noise nonces and fragments large
JSON-RPC messages into bounded records.
- Bounds handshake payloads, frames, streams, and message reassembly.
Runtime activation is in
[openai/codex#26245](https://github.com/openai/codex/pull/26245).
## Stack
1. **[openai/codex#26242](https://github.com/openai/codex/pull/26242)**:
Noise channel and relay transport
2. [openai/codex#26245](https://github.com/openai/codex/pull/26245):
remote registration and runtime activation
## Verification
- `just test -p codex-exec-server`
- Oversized initiator payload regression coverage
- `just fix -p codex-exec-server`

## Summary
Prevent dependency refreshes from silently downgrading Codex's bundled
SQLite to a release affected by the WAL-reset corruption bug.
SQLx 0.9 accepts a broad `libsqlite3-sys` range. An unrelated lock
refresh therefore moved Codex from `libsqlite3-sys 0.37.0` back to
`0.35.0`, changing the bundled SQLite runtime from 3.51.3 to 3.50.2.
SQLite documents the affected versions and fix in [The WAL Reset
Bug](https://www.sqlite.org/wal.html#the_wal_reset_bug) and the [SQLite
3.51.3 changelog](https://www.sqlite.org/changes.html#version_3_51_3).
## Why
Removes the realtime audio support from TUI.
## What Changed
- Removed the TUI `/realtime` and realtime `/settings` command paths.
- Deleted TUI voice capture/playback, WebRTC session handling,
audio-device selection UI, and recording-meter code.
- Removed TUI realtime tests and snapshots that covered the deleted
surfaces.
- Dropped the TUI-only `cpal` and `codex-realtime-webrtc` dependencies
and refreshed the Rust/Bazel locks.
## Why
First-party async traits should expose their `Send` contracts explicitly
without requiring `async_trait`. This completes the migration pattern
established in #27303 and #27304.
## What changed
- Replaced the remaining first-party `async_trait` traits with native
return-position `impl Future + Send` where statically dispatched and
explicit boxed `Send` futures where object safety is required.
- Kept implementations behavior-preserving, outlining existing async
bodies into inherent methods where that keeps the diff reviewable.
- Removed all direct first-party `async-trait` dependencies and the
workspace dependency declaration.
- Added a cargo-deny policy that permits `async-trait` only through the
remaining transitive wrapper crates.
- Updated `rand` from 0.8.5 to 0.8.6 to resolve RUSTSEC-2026-0097 and
keep the full cargo-deny check passing.
## Validation
- `just test -p codex-exec-server`: 216 passed, 2 skipped.
- `just test -p codex-model-provider`: 39 passed.
- `just test -p codex-core` and `just test`: changed tests passed;
remaining failures are environment-sensitive suites unrelated to this
migration.
- `cargo deny check`
- `just fix`
- `just fmt`
- `cargo shear`
- `just bazel-lock-check`
WIll make it easier to uprev when the new draft spec is supported.
Also updates reqwest where needed for compatibility but doesn't update
it everywhere since this is already a large diff.
The new version of rmcp handles certain kinds of authentication failures
differently, this patch includes support for identifying the failing scope
in a WWW-Authenticate header.
## Why
Codex stores thread, log, goal, and memory state in bundled SQLite
databases through SQLx. We have a suspected SQLite WAL-reset corruption
issue under heavy concurrent writer load, especially when multiple
subagents are active. The existing `sqlx 0.8.6` dependency kept us on an
older `libsqlite3-sys` / bundled SQLite, so this PR moves the SQLx stack
far enough forward to pick up the newer bundled SQLite library.
## What changed
- Bump the workspace `sqlx` dependency to `0.9.0`.
- Use the SQLx 0.9 feature names explicitly: `runtime-tokio`,
`tls-rustls`, and `sqlite-bundled`.
- Update `Cargo.lock` so `sqlx-sqlite` resolves through `libsqlite3-sys
0.37.0`.
- Refresh `MODULE.bazel.lock` for the dependency changes.
- Adapt `codex-state` to SQLx 0.9:
- build dynamic state queries with `QueryBuilder<Sqlite>` instead of
passing dynamic `String`s to `sqlx::query`;
- remove the old `QueryBuilder` lifetime parameter from helper
signatures;
- preserve SQLx's new `Migrator` fields when constructing runtime
migrators.
## Verification
- `just test -p codex-state`
- `just bazel-lock-check`
- `cargo check -p codex-state --tests`
## Summary
- Bump the workspace Rust toolchain from `1.93.0` to `1.95.0` across
Cargo, Bazel, CI, release workflows, devcontainers, and the Codex
environment config.
- Refresh `MODULE.bazel.lock` so the Bazel Rust toolchain artifacts
match the new version.
- Leave purpose-specific toolchains unchanged, including the
`argument-comment-lint` nightly and the upstream `rusty_v8` `1.91.0`
build pin.
- Includes fixes for new lints from `just fix` and a few codex-authored
fixes for lints without a suggestion.
