## Why
Guardian review evidence must remain available after a compacted thread is resumed or forked, while rolled-back or parent-local evidence must not grant authorization in a different context.
## What changed
- Store the bounded, model-invisible Guardian transcript alongside compacted rollout history and restore it from the newest surviving checkpoint during replay.
- Trim Guardian history at rollback boundaries, clearing it when the boundary has already been evicted.
- Preserve the checkpoint for user-initiated forks, but remove it when spawning a subagent so parent review evidence is not inherited.
- Keep the new rollout field optional for compatibility with existing compacted records and legacy readers.
## Testing
- Cover Guardian history across compaction, restart, paginated and pathless stores, user forks, rollback, bounded replay, serialization, and subagent forks.
GitOrigin-RevId: 6ab076d5e0c3aac4d6a41ebd50ba2b200c90213e
## What changed
- Resolve `link_id` from tool-call arguments when Apps metadata sets
`requires_explicit_link_id` to `true`.
- Reject the call before approval or execution when the required selector is
missing, empty, or not a string.
- Preserve catalog-provided account metadata for legacy Apps tools and leave
non-Apps MCP tools unchanged.
## Testing
- Add unit coverage for required selectors, malformed values, legacy
fallbacks, and non-Apps tools.
- Add end-to-end coverage for execution, approval prompts, and rejection when
an Apps call omits `link_id`.
GitOrigin-RevId: 667fd04102a3934d53ded020da6d1bf68a1ca3e5
## What changed
- Add `apps.<app_id>.links.<link_id>` configuration for overriding
`approvals_reviewer` and `default_tools_approval_mode` per connected account.
- Expose link settings through the app-server protocol and generated JSON and
TypeScript schemas.
## Testing
- Extend `config/read` coverage for populated, empty, and absent `links`
sections.
GitOrigin-RevId: 43004d2722439060fdadc5e5cd9ed3108774ecaf
## What changed
Add a `compression_enabled` attribute to each
`codex.app_server.codex_home.size_bytes` sample. The value reflects whether
`LocalThreadStoreCompression` is enabled in the effective startup configuration.
GitOrigin-RevId: c087d36b4e578245aee6cfe5257075dfd3bdd025
## What changed
- Make `local_thread_store_compression` compress cold rollout files across shared and forked histories without a separate compression mode.
- Retire `local_thread_store_shared_compression` while continuing to accept it in strict configuration without changing compression behavior.
- Read rollout files through the compressed-rollout reader when `codex exec resume` determines the latest turn's working directory.
## Testing
- Cover compression and restoration of an archived fork chain.
- Cover cwd-based resume selection when only the compressed rollout remains.
- Cover the removed compatibility key in strict configuration.
GitOrigin-RevId: 8edebf61eccc1f79cabb8e641f8982c76f337bf1
## Why
Reports from a large thread tree can exceed the rollout attachment limit, making
the threads involved in a failed Guardian review harder to diagnose.
## What changed
- Prioritize descendants with retained failed reviews when selecting bounded
report rollouts, while always preserving the reported thread.
- Include each selected thread's available Guardian trunk rollout alongside its
conversation rollout.
- Add a thread index attachment with selected filenames, bounded omission details,
retained failure threads, and the process-wide discarded-record count.
- Link failed-review records to their reviewed turn and target item when available.
## Testing
- Cover failed-review prioritization, bounded omission metadata, discarded-record
accounting, and turn/item linkage in Guardian report records.
GitOrigin-RevId: ae7916c27a3c279e899cd5a6ead8a4b7e0cc26a1
## What changed
- Add a shared `select_user_messages` helper in `guardian-context` that always
anchors the first user message and fills the remaining token budget from
newest to oldest.
- Use the helper for both core Guardian prompt rendering and the Guardian V2
async scorer so they apply the same retention policy.
## Testing
- Cover empty and single-message transcripts, over-budget anchors, and
newest-first selection across multiple token budgets.
GitOrigin-RevId: 7db246013875263ceb5806d2a6a19b4e2a3db1c4
## What changed
- Add `turn_trigger` and `codex_turn_source` to `codex_turn_event` analytics.
- Read the source from effective Responses metadata, preserving configured-over-client precedence and reflecting accepted steer metadata.
- Omit trigger and source values from analytics when they exceed the existing Responses metadata value limit.
## Testing
- Cover event serialization, turn lifecycle emission, configured and client source precedence, size limits, and source updates after steering.
GitOrigin-RevId: bbd45af4c6af52956d2394b722ea78e65e5b9bd7
## What changed
- Include the complete upstream `response.usage` object in
`ResponseUsageMetadata.metadata` while retaining the existing `amount` field.
- Expose the metadata through `rawResponse/completed` notifications and update
the generated JSON and TypeScript schemas.
## Testing
- Cover SSE, WebSocket, turn, and compaction completion paths.
GitOrigin-RevId: 6d79b1b4c92ac11abf43ec98f380b4868288a701
## What changed
- Add `tui.disable_paste_burst` as the preferred configuration key.
- Keep the top-level `disable_paste_burst` key as a legacy fallback.
- Give the `[tui]` setting precedence when both keys are present, while preserving configuration-layer precedence.
## Testing
Add configuration tests covering defaults, both key locations, precedence between the keys, and command-line overrides.
GitOrigin-RevId: e7fc9337d5b19d2fd9407e08b8301cee77a11779
## What changed
Emit the `codex.tui.start` counter once per TUI launch with an
`app_server_mode` label of `in_process`, `local_daemon`, or `remote`. Recording
the metric during startup keeps reconnects from counting as additional
launches.
GitOrigin-RevId: 7527f319b95ae53f5278fa16120120a433a29ae4
## Why
Marketplace source restrictions should cover curated plugins backed by the OpenAI plugins repository, not only user-configured marketplaces.
## What changed
- Validate both local curated catalogs against the existing OpenAI plugins Git source allowlist.
- Apply that policy to catalog discovery, installation, cached plugin and skill loading, and startup repository sync.
- Keep bundled and remote installed plugins independent of the curated Git source policy.
## Testing
Added coverage for exact and shorthand Git allowlist entries, host patterns, blocked and invalid rules, curated catalog variants, plugin skills, startup sync, and remote installed plugins.
GitOrigin-RevId: 04617acb4a93040c70a13759eb4ce872877ba211
## Why
Code-mode callbacks can outlive their initial request and run in separate tasks,
so their trace context must be preserved explicitly.
## What changed
- Preserve the execution context for code-mode callbacks and add spans for
nested tool invocations in the runtime and dispatch broker.
- Propagate each tool invocation span as the parent of its streamed gRPC
callback, falling back to the outer execution context when needed.
- Add a `codex.exec_server.process` span for each process lifetime, including
its process ID and completion result, without retaining the request span.
GitOrigin-RevId: a6059e34d895416f5517e51dad6ca0078355adca
## What changed
- Add the `plugin/reconcile` JSON-RPC method to synchronize installed remote plugin bundles and wait for required hook updates.
- Return affected plugin IDs with MCP, Apps, hooks, and skills refresh hints, plus remote update and materialization failures.
- Refresh loaded hook runtimes after relevant updates and return an empty result when plugins or backend authentication are unavailable.
## Testing
- Cover workspace and global bundle installs, unchanged passes, enablement changes, updates, removals, materialization failures, hook refreshes, and disabled plugins.
GitOrigin-RevId: 45c02518d71990d13eb09d56ed51505c91c66956
## What changed
- Verify image-generation extensions rebind permissions on every turn, preserving session grants while expiring turn-only grants.
- Cover executor skill reference reads under current filesystem permissions, including paginated reads, permission changes, and edits between pages.
- Verify oversized live executor skill prompts emit a warning without replacing previously injected prompt content.
GitOrigin-RevId: 1fc8eef409fa65db4bb1ab6a00408fe72c9e938f
## What changed
- Query workspace-visible turn estimates for ChatGPT-authenticated sessions through the appropriate Codex or ChatGPT endpoint.
- Track completed response IDs and emit `codex.turn.cost_microusd` only when the estimate is nonnegative, visible, and covers every observed response.
- Keep error response bodies out of turn-cost worker logs.
## Testing
- Cover both endpoint styles, nullable estimates, settlement validation, exact micro-USD conversion, and response-ID tracking.
- Add an app-server integration test that verifies a settled ChatGPT turn reaches the OTLP metrics exporter with its turn, conversation, and auth-mode attributes.
GitOrigin-RevId: 6ae3f8df729fad52984a0c6efafd8c96c7214e55
## Why
Composer drafts include attachments, mention targets, and deferred paste payloads in addition to visible text. Vim undo needs to restore that complete state as a single edit.
## What changed
- Add bounded, draft-level Vim undo history, with `u` as the configurable default binding in normal mode.
- Group complete Vim commands and insert sessions into undo steps, including direct composer changes such as pastes and attachments.
- Preserve undo, repeat, and search state when a reverse-history preview is canceled, and start fresh history when another prompt is accepted.
## Testing
- Cover grouped edits, custom bindings, history and search interactions, attachments, and large paste payloads.
GitOrigin-RevId: 12ecdb3c34a2d66f5d856aa2f82dc15bd91b230b
## Why
Moving between prompts in backtrack mode rebuilt every transcript renderable and
discarded their cached heights, causing the entire transcript to be laid out
again for each selection change.
## What changed
Rerender only the previously highlighted cell and the newly highlighted cell.
Keep all other renderables, cached heights, and the live tail intact while
continuing to scroll the selected prompt into view.
## Testing
Add regression tests that verify selection changes preserve unrelated height
caches and produce the same viewport and scroll position as a full rebuild,
including with a live tail and terminal width changes.
GitOrigin-RevId: 685a8ce65ecadef20521ce2ded7b516fdf8499c9
## What changed
- Show the exact `codex resume <thread-id>` command on its own indented line.
- When a thread has a name, also explain that users can run `codex resume` and select the named thread from the picker.
- Apply command highlighting to both resume options when color is enabled.
## Testing
- Cover unnamed, empty-name, named, colored, and embedded-session exit summaries.
GitOrigin-RevId: d97c04db8a34376c6d9ea839b515b04a384b85d1
## Why
Large input sent to a background terminal can require excessive wrapping work and fill the inline history view.
## What changed
- Limit inline input previews to 12 rendered rows and bound preview processing to 64 KiB.
- Show a transcript hint when input is omitted, while preserving the complete input in transcript and raw views.
- Keep URLs intact when they fit and truncate only the final overflowing line when needed.
## Testing
Add regression coverage for long wrapped input, narrow viewports, zero-width Unicode payloads, URLs, and inputs that fit within the preview budget.
GitOrigin-RevId: c20edf156d5c8364083b1690e41cabd29786a279
## What changed
- Retain bounded, process-local records for failed Guardian reviews, including the reviewed action, decision, status, model, instructions, and reviewer history.
- Add recent records from the reported thread and its descendants to log-enabled report uploads as `auto-review-failures.jsonl`.
- Preserve the action and decision while omitting oversized reviewer context, and exclude successful, ephemeral, and capture-disabled reviews.
## Testing
- Cover denied and invalid decisions, cleaned-up ephemeral reviewers, descendant-thread selection, record count and byte limits, and oversized-context fallback.
GitOrigin-RevId: 5f12f7605041c3c84e826e6bac1cf06b1518ab24
## Why
Audio models cannot reliably encode tool-generated clips shorter than 25 ms.
## What changed
- Measure the available audio frames in base64-encoded PCM and IEEE float WAV outputs.
- Replace clips under 25 ms with explanatory text while preserving surrounding Code Mode output.
- Leave clips at or above the threshold and unrecognized audio formats unchanged.
## Testing
- Cover the duration boundary across multiple sample rates and all supported `audio()` input forms.
- Verify bounded and truncated WAV chunks, output after `yield_control()`, and end-to-end mixed text and audio output.
GitOrigin-RevId: 342b4bdbc65db4238580f9cdc372763c2576eca5
## Why
Sandbox diagnostics could report `read-only` when a configured writable root did not yet exist, because policy labeling used filesystem-aware runtime root resolution.
## What changed
- Derive diagnostic policy labels from configured writable roots without inspecting the filesystem. Runtime sandbox authorization continues to use filesystem-aware resolution.
- Capture sandbox labels once per turn and reuse them for response metadata and tool-result metrics.
## Testing
Add coverage for missing project roots, denied roots, and deny rules on project subpaths.
GitOrigin-RevId: ccbdb8c32a1f44bfa63ae4d2ae1f9cc408e66b9c
## What changed
- Raise the Guardian message transcript budget from 10,000 to 20,000 tokens.
- Raise the per-message entry limit from 2,000 to 5,000 tokens.
GitOrigin-RevId: 93a92e3d806fd3bf005e6c27964babd7ed2f948e
## What changed
Dispatch `AppEvent::OpenAgentsOverview` in the daemon reconnect navigation test instead of simulating the Alt+A keyboard shortcut.
GitOrigin-RevId: 99729a39496ffb96747f6d0c4be0edf52d1ef3f6
## Why
Permission grants can belong to an executor whose path convention differs from
the local host, such as a Windows remote environment. Matching those grants
against a host-native working directory can reject valid permissions.
## What changed
- Normalize, materialize, and compare additional filesystem permissions using
the selected executor's URI-based sandbox context.
- Apply the same context-aware preapproval flow to `exec_command`,
`apply_patch`, and extension tools.
- Fail closed when symbolic temporary-directory or project-root permissions
cannot be resolved from executor metadata, while accepting opaque working
directory URIs when requested paths use the executor's convention.
## Testing
- Added coverage for reusing a Windows permission grant from a non-Windows
host, resolving symbolic temporary-directory grants, and normalizing paths
with an opaque Windows working directory.
GitOrigin-RevId: aee54350a25430a0443f8319e2bb0bbdc4f44282
## What changed
- Exercise Rust source discovery through a mocked `git ls-files` call, including files outside `codex-rs`, paths containing spaces, and stale entries that no longer exist.
- Assert that the formatter invokes `rustfmt` from `codex-rs` with the repository configuration in both format and check modes.
- Keep the multiline argument-comment lint fixture stable under formatting and update affected Rust test files to the expected style.
GitOrigin-RevId: 0cfffde1bb91bf620d2118bed1efc68466c0cca6
## Why
Realtime history should be recorded consistently for every Core host, including
when no app-server event listener is attached.
## What changed
- Move transcript segmentation, session boundaries, and backing-agent artifact
promotion into Core for paginated threads.
- Persist canonical realtime items through the thread store in event order and
emit dedicated history lifecycle events for hosts to present.
- Translate those Core events into the existing app-server realtime item
notifications without app-server persisting the items a second time.
## Testing
- Cover Core-only persistence across repeated sessions, ephemeral sessions,
accepted and rejected steering, typed input ordering, and artifact promotion.
- Verify app-server notifications correspond to the persisted timeline.
GitOrigin-RevId: 7cbef14129d77f6d6d7099b733be91f5279c55f5
## What changed
- Add an in-process `sideband_base_url` override to `ConversationStartTransport::ExistingCall`, while keeping app-server requests on the configured or default endpoint.
- Prefer the per-call endpoint when attaching and reconnecting a sideband, falling back to `experimental_realtime_ws_base_url` when no override is supplied.
- Preserve runtime authentication headers on the selected endpoint without adding bearer authorization.
## Testing
- Cover configured and per-call endpoint selection, authentication headers, call-specific handshake paths, and reconnect behavior.
GitOrigin-RevId: 16c439fe0a9ff8bcdda4ec615bb9983e30935052
## What changed
- Start the composer in Vim Insert mode when Vim is enabled and return to
Insert mode after submissions and slash-command dispatch.
- Record the fresh Insert session as a Vim edit so `.` can repeat text entered
in a new draft.
- Keep `/` and `?` as Normal-mode composer searches, and let Backspace cancel
an empty search query and any pending operator without changing the draft.
## Testing
- Add coverage for startup, submitted and queued drafts, inline and goal slash
commands, repeatable edits, and canceled searches.
GitOrigin-RevId: 1a5ee30c44685d2b2a037e46c3ab4ab611024919
## What changed
- Add `auto_review.node_repl_policy` to model messages for `node_repl` and `cua_repl` reviews.
- Use the reviewer model's configured policy, falling back to the bundled policy when the field is absent and skipping injection when it is explicitly empty.
- Include the effective policy in Guardian session reuse checks and reject unsafe parent-model fallback transitions that would change it.
## Testing
- Cover catalog, bundled, and explicitly empty policies across Node and CUA review paths.
- Verify that policy changes invalidate cached reviewer sessions and incompatible fallback transitions.
GitOrigin-RevId: 51c0bdfed9b464091b6eb47d91ca5a0990d7a315
## What changed
- Keep the agent command center visible with its cached inventory and draft while reconnecting, then refresh it without losing the selected task.
- Allow cached, unavailable conversations to reattach when selected while preserving their drafts, recap progress, and runtime permissions.
- Report an unsubmitted rename when its target disappears during refresh, and continue to quarantine queued input instead of resending it automatically.
## Testing
- Add a Unix socket replacement test covering command-center recovery with and without an active conversation, failed reconnects, inventory changes, and subsequent live task input.
GitOrigin-RevId: 774aca2dfb8358e9abd6a2e2ef0d509646648f66
## What changed
- Open the agents overview with Left from an empty, focused composer in local-daemon sessions.
- Keep the shortcut inactive while editing text, using transient input surfaces, or when Left has been explicitly remapped.
- Show the contextual shortcut in the footer and shortcuts overlay.
- Leave the configurable `open_agents` action unbound by default instead of assigning `Alt+A`.
## Testing
- Add coverage for session eligibility, input-state guards, editor and Vim remaps, event dispatch, and footer rendering.
GitOrigin-RevId: ef17db3d9d09c3a08c3f7353c5b8a02f2b61c696
## What changed
- Reconnect out-of-process TUI sessions after the app-server transport drops, bootstrap a fresh client, and resume the active thread.
- Preserve cached transcripts, drafts, runtime settings, task-tool capabilities, and live notification routing across the new connection.
- Keep recovered or possibly submitted input paused for manual review instead of resending it, and leave conversations that cannot be resumed available as read-only cached views.
- Show reconnect progress and actionable failure states while still allowing drafts to be edited or copied.
## Testing
- Add app-level coverage for successful recovery, failed and unavailable resumes, input quarantine, and preserved session state.
- Extend the terminal integration test to verify that a draft survives reconnection, the thread is resumed without starting a turn, and notifications arrive through the replacement connection.
GitOrigin-RevId: 5dcb867c89e226a0c545d6313a77424c233cd47a
## What changed
- Add the `codex-config-schema` workspace and Bazel crate for the
`codex-write-config-schema` binary.
- Preserve `codex-rs/core/config.schema.json` as the default output location.
- Update `just write-config-schema` to run the new crate and remove the schema
generator's `clap` dependency and binary target from `codex-core`.
GitOrigin-RevId: 7447f97d6e44d1077b16d2d850f8a8add9117ea6
## Why
Streaming can temporarily hide the status row, but its elapsed time is still
needed when the row returns and when the final `Worked for` duration falls back
to the local clock. Approval prompts must also keep that clock paused.
## What changed
- Own the pause-aware status timer in the bottom pane independently of the
optional status row.
- Preserve elapsed time and modal pause state while hiding or restoring the row,
and reset the clock for new turns and Windows sandbox setup.
- Use the independent timer as the fallback for the final turn duration.
## Testing
Add timer unit coverage and TUI tests for hidden rows, outstanding approvals,
fallback turn durations, and fresh Windows sandbox setup clocks.
GitOrigin-RevId: a77931e465d5aedd4a8cd606a3a3117d1bb37ce7
## Why
Resumed threads need to continue per-turn and per-thread token totals without scanning arbitrarily far beyond the latest compaction checkpoint.
## What changed
- Add durable `TokenUsageRecord` rollout items with response, turn, thread, session, and root-turn attribution.
- Restore accumulated usage on resume and snapshot the latest record plus the compaction response ID in compaction checkpoints.
- Preserve root-turn lineage in persisted turn context, while ensuring forked child threads start with their own usage totals.
## Testing
- Cover usage accumulation across multiple responses and resumed turns.
- Cover local and remote compaction checkpoints, invalid remote compaction output, rollout reconstruction, and fork isolation.
GitOrigin-RevId: ef9e0c4a9102a08a2c382be4cdac68c84353c90a
## Why
Losing an external app-server connection can leave a submission's outcome uncertain. The TUI must preserve local work without retrying it or allowing stale server events to trigger more actions.
## What changed
- Enter an offline state when an external app-server transport disconnects during startup, event streaming, or submission.
- Keep conversation drafts, queued input, expanded pastes, attachments, and agent-overview input editable while blocking submissions, remote actions, and automatic queue replay.
- Show a connection-lost notice that directs users to copy their work and relaunch, while retaining `Ctrl-C` and an empty-composer `Ctrl-D` as quit shortcuts.
- Cancel pending views and asynchronous work, and ignore stale completions after the disconnect. Embedded app-server behavior is unchanged.
## Testing
Added unit, snapshot, and pseudo-terminal coverage for lost startup and mutation replies, offline draft editing, queued-input recovery, stale-event quarantine, agent-overview behavior, and end-to-end preservation without reconnection or resubmission.
GitOrigin-RevId: 7219a95fad676dda447d625db9e465345b469d58
## What changed
- Add context-aware normalization, materialization, and intersection helpers for additional filesystem permissions.
- Resolve project roots, home-relative deny globs, temporary directories, and filesystem roots from the executor's `FileSystemSandboxPolicyContext` while preserving URI path conventions and symlinked paths.
- Keep deny constraints when intersecting grants across POSIX, Windows, and UNC paths, and reject incompatible path conventions when executor context is available.
## Testing
- Cover cross-convention validation, empty temporary-directory contexts, home-relative deny globs, and rooted deny globs for POSIX, Windows, and UNC paths.
GitOrigin-RevId: 14fd866a17a0ac4a595aa4f0e2fb82bfae1a8838
## Why
Archiving a thread only needs to locate rollout files that have not already
been moved, so reading the entire rollout archive on every request is
unnecessary.
## What changed
- Add `RolloutReferenceIndex::scan_unarchived` to scan only the active
`sessions` directory.
- Use the active-only index when archiving threads while retaining full scans
for operations that require archived-history reference counts.
- Cover discovery of compressed and uncompressed active rollouts and exclusion
of archived and unrelated rollouts.
GitOrigin-RevId: 46367127578f20bfa46a8db5c6f2b7f59d29f7a9
## What changed
- Add `McpEventStreamManager` to own event stream workers by thread and subscription.
- Wait for activation before completing a start, tag updates with a stream attempt ID, and keep active streams alive independently of their originating runtime.
- Support cancellation and shutdown without depending on output queue capacity, and close streams when MCP access changes or an event server is removed.
- Reconnect reloaded threads to surviving streams so server removal still cancels them.
## Testing
Add coverage for activation, replacement attempts, task reloads, cancellation before activation, full output queues, access changes, and shutdown.
GitOrigin-RevId: b7156bbe62f9375b2138eb62868f052124e2a884
## What changed
- Add `VoiceHost` to resolve the packaged voice helper, launch it with an
allowlisted environment, perform the protocol handshake, and enforce bounded
shutdown and process cleanup.
- Preserve native executable path encoding in the pipe process APIs.
- Add `third_party/voice/assemble_package.py` to create a fresh package copy
containing a target-compatible helper and a provenance manifest with file
hashes.
## Testing
- Cover installed helper lifecycle, build matching, missing and symlinked
helpers, non-UTF-8 package paths, environment filtering, package validation,
target pairing, and failure cleanup.
GitOrigin-RevId: f893074b36ae6bb9bcedc00fbe7af6bb72745f4c
## Why
Paginated threads can accumulate wake turns with no user-message boundary. The
reverse context scan could not use those turns as a bounded replay cutoff, even
when a compaction and its resume state provided everything needed to reconstruct
the latest model context.
## What changed
Treat a full world-state snapshot that survives the latest compaction as a
durable baseline when it is paired with a compatible turn context. This lets the
scan stop at empty wake turns while still scanning further back for patches,
snapshots before compaction, or missing and mismatched turn contexts.
## Testing
Add coverage for repeated empty wake turns and verify that bounded replay
matches full rollout reconstruction across successive compaction windows.
GitOrigin-RevId: ae90c5f939c660ea539fbfc11128cc7259efaa9c
## Why
Event subscriptions may need to outlive the MCP runtime associated with a task.
## What changed
- Add `McpEventStreamOpener`, which retains the hosted Apps MCP connection settings and opens each event stream with an independent client.
- Keep subscription cancellation tied to account changes and removal of the task's event server, including when cancellation ownership is forwarded across runtime replacement.
- Expose the opener and cancellation forwarding through `McpResourceClient`.
## Testing
Add an HTTP transport test that shuts down the runtime, refreshes credentials for the same account, and verifies that a new event stream connects with the current authorization and receives notifications.
GitOrigin-RevId: e102aa382e63121661ff0567f7523515e459922d
## What changed
- Add `codex-realtime-webrtc` with a length-prefixed, 256-byte JSON control protocol for `hello`, `ready`, `close`, and `closed` messages.
- Add a hardened `codex-voice-host` binary that validates protocol and build compatibility, handles orderly shutdown and parent pipe loss, and exposes its build commit.
- Keep this initial foundation limited to process lifecycle management; it does not open audio devices, load native plugins, negotiate WebRTC, or enable voice in the TUI.
## Testing
- Exercise the helper as a subprocess, covering handshake, explicit close, parent pipe loss, malformed frames, incompatible builds, and invalid message order.
GitOrigin-RevId: 6d8d7dd7ba5c4886879882d79314d235f6ab7cf4
## Why
Windows builds combine Cygwin build tools with native MSVC outputs. On ARM64,
Cygwin can run under x64 emulation, so inferred host details and untranslated
paths can select the wrong target or leak POSIX paths into native metadata.
## What changed
- Convert libffi source, prefix, and shell paths with `cygpath`, preserve
`USERPROFILE`, and pass explicit build and host targets.
- Configure libffi's MSVC and libtool environment to produce and install its
shared library and import library, including across recursive make calls.
- Reject libffi pkg-config output containing `/cygdrive/` paths and enable
Opus NEON support for `aarch64-pc-windows-msvc`.
- Document the additional Windows build prerequisites.
## Testing
- Extend `test_build_native.py` with Windows path conversion, x64 and ARM64
target configuration, recursive make flag propagation, pkg-config, and Opus
coverage.
GitOrigin-RevId: 12eb4ff83e141aa069abd68af4839f06e4c45b8f
## What changed
- Emit a separate history cell for each completed command instead of grouping
consecutive successes into a `Ran N commands` summary.
- Preserve `Explored` grouping for related file reads, searches, and listings.
- Replay completed commands as individual entries so their output and failure
status remain visible.
## Testing
- Update TUI tests and snapshots for live exploration and replayed commands.
GitOrigin-RevId: 7dafe0b7846fc89784093791a6be137a1b1ab8ff
## What changed
- Add `McpEventStream::open` to construct event stream requests and keep the
underlying `RmcpClient` alive until the subscription completes or is canceled.
- Stop retaining the broader `McpServerConnection` for the lifetime of an event
stream, and remove the connection-returning lookup helper.
- Use MCP event server terminology in event discovery and subscription errors.

## Why
The pinned voice source inputs can be prepared but do not yet provide compiled
native libraries for downstream integration.
## What changed
- Add `build_native.py` to build a shared-library prefix for the supported voice
dependencies on native x64 and ARM64 GNU/Linux, macOS, and Windows MSVC hosts.
- Require explicit toolchain inputs, isolate dependency discovery to the output
prefix, and record command logs and build state for provenance and failures.
- Expose the recipe and source inputs through `//third_party/voice:build_inputs`
and document its prerequisites, outputs, and integration boundaries.
## Testing
- `PYTHONSAFEPATH=1 python3 -m unittest discover -s third_party/voice -p 'test_build_native.py'`
