Summary

  • Record upstream rust-v0.143.0 ancestry with an ours merge so this sync can merge the real upstream release range instead of replaying the previous squashed fork sync.
  • Merge upstream rust-v0.144.0, preserving upstream release commits in history.
  • Resolve fork-specific conflicts around account pool behavior, fork release URLs, update notices, and test helper/API drift.

Deletion audit

Only two deleted paths appear relative to main, both intentional upstream removals:

  • codex-rs/.github/workflows/cargo-audit.yml from upstream 4b64bf0751 chore: remove inert cargo audit workflow (#31461).
  • codex-rs/exec-server/testing/windows_exec_server.rs from upstream f158b31db5 test: generalize exec-server fixture (#31422); upstream replaces it with generalized exec_server.rs coverage.

## Why

Core and tools need to request MCP elicitation without constructing
app-server wire payloads. The request should remain a neutral protocol
concept until app-server serializes it for a client.

## What changed

- Switched core and tools to
`codex_protocol::approvals::ElicitationRequest`.
- Derived turn and server context inside core instead of carrying
app-server request types through lower layers.
- Kept the app-server payload unchanged through an explicit boundary
conversion.
- Removed the remaining production app-server-protocol dependency from
tools.

## Stack

This is PR 5 of 6, stacked on [PR
openai#29723](openai#29723). Review only the
delta from `codex/split-connector-metadata-types`. Next: [PR
openai#29725](openai#29725).

## Validation

- `codex-core` MCP coverage passed: 87 tests.
- Tools elicitation and app-server round-trip coverage passed.
Summary
- Emit `codex_plugin_install_requested` when a validated plugin install
request is made, before the user accepts or declines the elicitation.
- Record the exact model-visible plugin ID, remote plugin ID, required
connector IDs, stable suggestion ID, and `endpoint_recommendation` vs
`legacy_discovery` source.
- Keep `suggest_reason` out of telemetry and leave connector-only
install requests unchanged.

Rollout
- Backend/schema dependency:
openai/openai#1065270
- Land the backend PR before this producer starts sending the event.

Validation
- `just test -p codex-analytics` (83 passed)
- `just test -p codex-core request_plugin_install` (17 passed)
- `just fix -p codex-analytics`
- `just fix -p codex-core`
- `just fmt`
- `git diff --check`
## Why

When Codex uses a remote `ExecutorFileSystem`, every `get_metadata` call
is an exec-server round trip. Upward discovery currently pays those
round trips serially in two latency-sensitive places:

- session startup, while locating the configured project root before
loading `AGENTS.md`; and
- Git-root discovery, which runs before per-turn Git diff enrichment.

The goal is to remove the serial ancestor dependency without adding a
new filesystem RPC, JSON-RPC batch method, Git executable dependency, or
cache.

## Example

Assume this layout, with `.git` as the configured project-root marker:

```text
/workspace/repo/.git
/workspace/repo/AGENTS.md
/workspace/repo/crates/core/    <- cwd
```

The marker probes have this required precedence:

```text
1. /workspace/repo/crates/core/.git
2. /workspace/repo/crates/.git
3. /workspace/repo/.git
4. /workspace/.git
5. /.git
```

Previously, probe 2 was not sent until probe 1 returned, and probe 3 was
not sent until probe 2 returned. With this change, the client lazily
keeps up to eight ordinary `fs/getMetadata` requests in flight, but
consumes their results in the order above. Codex must still learn that
probes 1 and 2 are absent before accepting probe 3, so the nearest root
always wins. Once probe 3 succeeds, the client has its answer and stops
awaiting probes 4 and 5. Requests that were already sent may still
finish on the worker.

For the marker phase alone, with a 50 ms client-to-worker round trip and
fast local metadata calls, finding the root at probe 3 changes from
roughly three serialized round trips (150 ms) to one round trip plus
worker processing. The later `AGENTS.md` candidate phase remains
separate and ordered.

Only after `/workspace/repo` is selected does `AGENTS.md` discovery
check instruction candidates, in root-to-cwd order:

```text
/workspace/repo/AGENTS.override.md
/workspace/repo/AGENTS.md
/workspace/repo/crates/AGENTS.override.md
/workspace/repo/crates/AGENTS.md
/workspace/repo/crates/core/AGENTS.override.md
/workspace/repo/crates/core/AGENTS.md
```

The first configured candidate found in each directory wins. These
checks remain ordered and no instruction candidate above
`/workspace/repo` is issued. Git-root discovery uses the same bounded
lookup with only `.git` as the marker.

## What changed

- Added a client-side find-up helper that generates `ancestor x marker`
probes lazily, nearest directory first and configured marker order
within each directory.
- Uses an ordered concurrency window of eight scalar metadata requests.
This bounds executor load while preserving nearest-root and marker
precedence.
- Reuses the helper for both configured project-root discovery and
remote Git-root discovery.
- Keeps Git ancestor and marker construction in `AbsolutePathBuf`,
converting only each complete `.git` probe to `PathUri`. This preserves
native paths that require an opaque URI fallback, such as Windows
namespace paths.
- Preserves existing error behavior: `AGENTS.md` discovery propagates
non-`NotFound` metadata errors, while Git discovery treats a failed
marker probe as absent and continues upward.
- Reads each discovered `AGENTS.md` directly instead of statting it a
second time.

No filesystem trait or exec-server protocol method is added. An empty
`project_root_markers` list performs no ancestor-marker I/O and checks
instruction candidates only in `cwd`. This change also deliberately does
not cache roots across turns.

## Symlinks

Upward traversal remains **lexical**. The helper does not canonicalize
`cwd`; it appends marker names to the supplied path and walks that
path's textual parents. The filesystem performs the actual metadata/read
operation, and the current local and exec-server implementations follow
live symlink targets.

For example:

```text
/tmp/pkg -> /workspace/repo/packages/pkg
cwd = /tmp/pkg/src
actual Git marker = /workspace/repo/.git
```

The lexical probes are `/tmp/pkg/src/.git`, `/tmp/pkg/.git`,
`/tmp/.git`, and `/.git`. They do not jump from `/tmp/pkg` to the
target's parent `/workspace/repo`, so this spelling of `cwd` does not
discover `/workspace/repo/.git`. That is the existing behavior and is
unchanged by this PR.

Conversely, if `/tmp/repo -> /workspace/repo`, then probing
`/tmp/repo/.git` follows the directory symlink and finds
`/workspace/repo/.git`; the reported root remains the lexical path
`/tmp/repo`. A live symlink used directly as `.git`, another configured
marker, or `AGENTS.md` is also followed. A symlinked `AGENTS.md` is
loaded when its target is a regular file, while a broken symlink behaves
as `NotFound`.
## Why

Remote-control HTTP requests applied the authentication headers and then
appended `ChatGPT-Account-ID` again with
`reqwest::RequestBuilder::header`. Since reqwest appends, the wire
request could contain the same header twice. Intermediaries may coalesce
duplicate values into `uuid,uuid`, which is not a valid account ID.

## What changed

- Build remote-control request authentication headers in one place.
- Apply provider headers first, then use `HeaderMap::insert` for the
explicit account ID. This preserves the current account-ID precedence
and all other authentication headers while ensuring exactly one account
header is sent.
- Preserve duplicate HTTP headers in the test harness and assert exactly
one account header for enroll, refresh, list, and revoke requests.

## Validation

Added focused coverage for:

- Adding the explicit account header when the auth provider omits it.
- Replacing multiple provider-supplied account values, including a
differently cased header name.
- Preserving authorization and routing headers while replacing only the
account header.
- Rejecting invalid account header values before sending a request.
- Emitting exactly one account header for enroll, refresh, list, and
revoke requests.
- Maintaining header uniqueness across unauthorized recovery, retry, and
error-response paths.
- Emitting exactly one installation header for enroll and refresh
requests.

Checks run:

- `just test -p codex-app-server-transport request_headers`: 3 passed
- `just test -p codex-app-server-transport remote_control_http_mode`: 6

- `just test -p codex-app-server-transport clients_tests`: 6 passed

## Why

Connector declarations currently enter Codex through broad plugin
capability summaries, then MCP setup, turn tooling, and `app/list` each
reconstruct the same information. That makes executor-selected
connectors difficult to add without coupling connector behavior to the
host plugin loader.

This PR introduces a small connector-owned value that later stack layers
can populate before thread startup.

## What changed

- Move the pure app-declaration parser into `codex-connectors`,
preserving declaration order and category cleanup while leaving
host-side validation and deduplication unchanged.
- Add an immutable `ConnectorSnapshot` with ordered connector IDs and
plugin display-name provenance.
- Adapt the existing local-plugin capability summaries into that
snapshot at current consumer boundaries.
- Use the snapshot for MCP tool provenance, turn connector inventory,
and `app/list`.
- Keep the crate API narrow: no test-only snapshot accessors are
exposed.

The externally visible behavior is unchanged. Connector tools still come
from the orchestrator-owned `/ps/mcp` server, and local plugin
enablement remains owned by the existing plugin loader.

## Stack scope

This is the foundation only. It does not read selected executor packages
or change thread startup. openai#29852 adds the executor-backed declaration
reader, and openai#29856 composes selected declarations into a thread
snapshot.
## Why

`PathUri::join` normalized `..` for relative paths, but its
absolute-path branch rebuilt URIs through `url::PathSegmentsMut::push`,
which skips dot segments. `/tmp/a/../b` therefore resolved to `/tmp/a/b`
instead of `/tmp/b`.

## What changed

Normalize absolute native path segments before constructing the file
URI. Parent traversal now clamps at POSIX roots, Windows drive roots,
and UNC share roots, including paths with repeated separators.

Add platform-independent coverage for POSIX, drive, UNC, root-clamping,
and repeated-separator cases.

## Manual validation

- `just test -p codex-utils-path-uri`
## Why

Selected capability roots can live on a different executor and operating
system from app-server. Their connector declarations must therefore be
read through the executor that owns the package, without converting
executor URIs into host paths.

This PR adds that authority-bound reader without activating connectors
or changing thread startup.

## What changed

- Add a small `codex-connectors-extension` crate for executor-owned
connector I/O.
- Read only the app configuration explicitly declared by the resolved
plugin manifest.
- Read through the `ExecutorFileSystem` retained by
`ResolvedExecutorPlugin`; there is no host-filesystem fallback or
default-file probe.
- Keep `PathUri` values intact so Windows, Unix, and remote executor
paths work from any orchestrator OS.
- Return full `AppDeclaration` values so the caller retains declaration
names and categories for routing.
- Preserve the selected plugin ID and exact executor URI in read and
parse errors.

The contract is intentionally narrow: selected packages are trusted,
valid packages and packages that provide connectors explicitly declare
their app configuration.

## Stack scope

This PR is stacked on openai#29851. It only provides the executor-backed
reader. openai#29856 resolves selected roots at thread start, freezes their
connector snapshot, and contains the remote-capable end-to-end authority
test for the complete path.
## Why

Several users have reported data loss from this bug, including tracked
files being deleted or replaced and branches appearing to be reset to
the curated plugins repository. This can happen during startup, before
the model chooses to edit anything.

Ambient repository variables such as `GIT_DIR` and `GIT_WORK_TREE` can
override the repository selected by `git -C`, redirecting startup sync's
`git reset --hard` and `git clean -fdx` into the user's active
workspace.

## What

Route every startup-sync Git invocation through a shared command builder
that removes repository-local environment variables before execution.
Add regression coverage to keep those variables isolated.

Fixes openai#27416
## Summary

- expose the interruptible sleep tool as `clock.sleep` instead of
top-level `sleep`
- keep `clock.curr_time` and `clock.sleep` in the same model-visible
namespace when both features are enabled
- update existing core and app-server integration coverage to issue
namespaced sleep calls

## Why

Sleep is a clock operation. Grouping it with `clock.curr_time` gives the
model a more coherent tool surface without changing the sleep feature
gate or runtime behavior.

## Validation

- `just test -p codex-core sleep_tool_follows_feature_gate`
- `just test -p codex-core any_new_input_interrupts_sleep`
- `just test -p codex-app-server
sleep_emits_started_and_completed_items`
## Summary

- move sleep tool enablement from top-level `[features].sleep_tool` to
`[features.current_time_reminder].sleep_tool`
- remove the standalone `Feature::SleepTool` flag and gate `clock.sleep`
from resolved current-time configuration
- update config schema, config-lock materialization, and existing sleep
coverage

Stacked on openai#29907.
## Why

Users who run Codex remote control through daemon mode can keep the
daemon running, but they do not have a CLI path to mint the short-lived
manual pairing code needed to connect another device. Without this
command, they need to speak app-server JSON-RPC directly.

Related: openai#25675

## What Changed

- Added `codex remote-control pair`, which connects to the existing
daemon control socket and calls `remoteControl/pairing/start` with
`manualCode: true`.
- Kept the command non-lifecycle-mutating: it does not start, enable, or
restart the daemon.
- Human output labels the manual code as `Pairing code: ...`; `--json`
preserves the full pairing response.
- Added daemon socket-client, CLI formatting, and parser coverage.

## Verification

- `remote_control_client::tests::start_pairing_requests_manual_code`
verifies the daemon client sends `{ "manualCode": true }` and parses the
complete response.
-
`remote_control_cmd::tests::remote_control_pairing_human_output_labels_the_manual_code`
verifies the human-facing output.
## Why

This PR adds a configurable `<context_window_guidance>` developer
section immediately after `<context_window>`. Harness integrations need
this section to give the model deployment-specific instructions for
preparing for context-window transitions.

## What changed

- Add an optional `features.token_budget.guidance_message` config with a
1,000-byte runtime cap and generated schema support.
- Render configured guidance as a developer `ContextualUserFragment`
wrapped in `<context_window_guidance>` immediately after
`<context_window>`.
- Omit the section when guidance is unset, empty, or whitespace-only.
- Preserve the resolved value in config locks and classify persisted
guidance as contextual developer content.
- Add integration coverage for rendered content and ordering.
This is the final plugin sharing PR in the 5-PR stack. It applies the
remaining TUI polish for remote plugin catalog rows and tabs:
admin-disabled plugins now read as blocked/view-only instead of looking
toggleable, admin-installed/default-installed plugins count and sort
like installed plugins, plugin search matches richer metadata, and an
empty successful `Shared with me` section stays hidden.

- Admin-disabled rows use a blocked marker, show `Disabled`, and keep
Enter-only detail behavior without a toggle hint.
- Admin-installed/default-installed plugins show as installed in counts,
ordering, tabs, and detail copy.
- Plugin search now matches descriptions and keywords in addition to
existing row metadata.
- Successful-empty `Shared with me` tabs are hidden, while loading,
error, workspace-empty, and real shared-plugin states remain visible.
- Updates coverage in
`plugins_popup_snapshot_shows_all_marketplaces_and_sorts_installed_then_name`,
`plugins_popup_admin_disabled_installed_plugin_has_no_toggle_hint`,
`plugins_popup_search_matches_plugin_descriptions`, and
`plugins_popup_remote_section_fallback_states_snapshot`.
- Updates snapshots `plugins_popup_curated_marketplace` and
`plugins_popup_empty_shared_section_hidden`.

## Why

ChatGPT session authentication was inferred from the reserved Codex Apps
server name. That couples credential routing to Codex Apps-specific
behavior and prevents other MCP endpoints hosted by ChatGPT from
explicitly using the current session.

The opt-in also needs a clear security boundary: an arbitrary MCP
configuration must not be able to redirect ChatGPT credentials to
another origin.

## What changed

- Add `use_chatgpt_auth` to HTTP MCP server configuration, defaulting to
`false`.
- Honor the setting only when the parsed server URL has the same HTTP(S)
origin as the configured `chatgpt_base_url`; otherwise remove the
capability before startup.
- Resolve bearer tokens and static or environment-backed authorization
headers before selecting authentication, with configured authorization
taking precedence over ChatGPT session auth.
- Enable the setting for the built-in Codex Apps and hosted plugin
runtime endpoints while keeping Codex Apps caching and tool
normalization scoped to the reserved server.
- Persist the setting through MCP config rewrite paths and expose it in
the generated config schema.
- Load the current login state for `codex mcp list` so reported auth
status matches runtime behavior.

## Verification

Core integration coverage exercises the complete streamable HTTP MCP
startup path and verifies that:

- a same-origin opted-in server receives the current ChatGPT access
token;
- an explicitly configured authorization header takes precedence;
- a different-origin server completes MCP initialization and tool
listing without receiving any ChatGPT authorization header.
## Why

`WorldState` currently keeps its diff baseline as live Rust objects
keyed by process-local `TypeId`. That baseline cannot be written to a
rollout or restored after resume, so Codex reconstructs an approximation
from `TurnContextItem`.

This is the first change in the WorldState persistence stack. It gives
every section a stable persisted identity and a compact serializable
comparison snapshot without changing rollout behavior yet.

## What changed

- Require each `WorldStateSection` to define a stable ID and
serializable snapshot type.
- Reject duplicate section IDs when constructing `WorldState`.
- Persist a dedicated environment comparison snapshot using
model-visible strings instead of runtime path types.
- Store only `WorldStateSnapshot` in `ContextManager`, removing the
parallel live-object baseline.
- Render diffs by restoring each section's typed snapshot; invalid
snapshots fall back to a full section render.
- Omit null object fields for future RFC 7386 patches while preserving
null values inside arrays.

Follow-up PRs will record full snapshots and merge patches, then restore
the baseline during resume, fork, and rollback.

## Test plan

- WorldState snapshot tests cover stable IDs, duplicate rejection, null
omission, and array preservation.
- Environment tests cover persistence-safe snapshot values and existing
diff rendering.
- ContextManager baseline deduplication and session context-update
persistence tests.

Related: openai#29249
## Why

MCP authentication has distinct OAuth and ChatGPT-session flows.
Representing that choice as `use_chatgpt_auth` makes one flow implicit
and allows the configuration model to express the distinction only
through a boolean.

ChatGPT credential forwarding also needs a first-party trust boundary. A
configurable `chatgpt_base_url` controls routing, but must not grant an
MCP server permission to receive session credentials.

This change builds on openai#29733, where the boolean was introduced.

## What changed

- Replace `use_chatgpt_auth` with an `auth` field backed by the
exhaustive `McpServerAuth` enum.
- Support `auth = "oauth"` and `auth = "chatgpt"`, with OAuth remaining
the default.
- Trust only the origin derived from the existing hardcoded
`CHATGPT_CODEX_BASE_URL` when granting ChatGPT auth to an MCP server.
- Keep configured bearer tokens and authorization headers ahead of the
selected authentication flow.
- Update config writers, schema output, fixtures, and integration-test
setup to use the enum.

## Verification

Integration coverage exercises the complete streamable HTTP startup path
in two independent configurations:

- A directly constructed MCP configuration verifies that matching an
overridden `chatgpt_base_url` does not grant ChatGPT auth.
- A persisted `config.toml` containing an attacker-controlled
`chatgpt_base_url` and `auth = "chatgpt"` verifies the same boundary
through normal config parsing.

Both tests complete MCP initialization and tool listing and assert that
the full captured request sequence contains no authorization headers.
Separate integration coverage verifies that configured authorization
takes precedence over ChatGPT auth.
## Why

The process-owned code mode implementation needs an explicit, bounded
wire contract before either side depends on it. Keeping framing and
message semantics in `codex-code-mode-protocol` gives the client and
sidecar one shared source of truth and makes compatibility failures
detectable during connection setup.

## What changed

- adds a versioned client/host handshake with required and optional
capabilities
- defines operation requests and responses for session lifecycle and
cell control
- defines reverse delegate request, response, cancellation, and
cell-closure messages
- adds a four-byte little-endian length-prefixed JSON codec with a hard
frame cap
- rejects malformed frames, unknown fields, invalid identifiers, and
unsupported protocol states
- locks the wire representation down with explicit JSON round-trip tests

## Testing

- `just test -p codex-code-mode-protocol`

## Stack

Part 1 of 6. Followed by
[openai#29805](openai#29805).
# What

- Carry installed remote release versions through remote plugin
summaries as `localVersion`.
- Keep the app-server mapping a pure adapter by populating that value in
the remote catalog layer.

# Why

Remote plugin summaries always returned `localVersion: null` even after
their versioned bundles had been installed locally. Consumers such as
scheduled-task template discovery use `localVersion` to resolve a
plugin's materialized root, so templates from remote curated plugins
were silently skipped.
## Why

`WorldState` currently remembers its model-visible diff baseline only in
memory. That leaves no durable source for restoring the exact baseline
after resume, fork, rollback, or compaction.

This is the second PR in the WorldState persistence stack, built on
openai#29833 and following openai#29249. It records durable state transitions; the
next PR will replay them during rollout reconstruction.

## What

- Add a `world_state` rollout item containing either a full snapshot or
an RFC 7386 JSON Merge Patch.
- Persist a full snapshot after initial context and after compaction
establishes a new context window.
- Persist non-empty patches when later sampling steps or turns advance
the WorldState baseline.
- Write model-visible history before its matching WorldState record, so
an interrupted write can only cause a safe repeated update on replay.
- Preserve WorldState records for full-history forks while excluding
them from thread previews, metadata, and app-server history
materialization.

Older binaries read rollout lines independently, so they skip the
unknown `world_state` records while retaining the rest of the thread.

## Testing

- `just test -p codex-core
snapshot_merge_patch_changes_and_removes_nested_values`
- `just test -p codex-core
world_state_baseline_deduplicates_until_history_is_replaced`
- `just test -p codex-core
deferred_executor_compaction_preserves_then_updates_environment_once`
- `just test -p codex-protocol`
- `just test -p codex-rollout`
- `just test -p codex-state`
- `just test -p codex-thread-store`
- `just test -p codex-app-server-protocol`
## Why

Ultra should be one user-facing reasoning selection for work that
benefits from both maximum reasoning and proactive multi-agent
delegation. Without it, clients must coordinate maximum reasoning with
the experimental `multiAgentMode` setting, even though the inference
backend still expects its existing `max` effort value.

This change makes reasoning effort the source of truth: clients select
`ultra`, core derives proactive multi-agent behavior when the turn is
eligible for multi-agent V2, and inference requests continue to use the
backend-compatible `max` value.

## What changed

- Add `ultra` as a first-class reasoning effort and preserve
model-catalog ordering when exposing it to clients.
- Convert `ultra` to `max` at the inference request boundary, including
Responses HTTP/WebSocket requests, startup prewarm, compaction, and
memory summarization.
- Derive effective multi-agent mode per turn from effective reasoning
effort:
  - eligible multi-agent V2 + `ultra` → `proactive`
  - eligible multi-agent V2 + any other effort → `explicitRequestOnly`
- V1 or otherwise ineligible sessions → no multi-agent mode instruction
- Keep the derived effective mode in turn context history so successive
turns can emit a developer-message update only when the effective mode
changes.
- Remove selected multi-agent mode from core session configuration, turn
construction, thread settings, resume/fork restoration, and subagent
spawn plumbing. Subagents inherit reasoning effort and derive their own
effective mode.
- Retain the experimental app-server `multiAgentMode` fields for wire
compatibility while marking them deprecated. Request values are accepted
but ignored; compatibility response fields report `explicitRequestOnly`.
- Display Ultra in the TUI using the order supplied by `model/list`.

## Validation

- `just test -p codex-core ultra_reasoning_uses_max_for_requests`
- `just test -p codex-tui model_reasoning_selection_popup`
## Why

Persisting `WorldState` snapshots and patches is only useful if resume
and fork restore that exact comparison baseline. Rebuilding it from
`TurnContextItem` loses section state and can either repeat or suppress
model-visible updates.

This is the third PR in the WorldState persistence stack, built on
openai#29835.

## What

- Replay full WorldState snapshots and RFC 7386 patches through the
existing rollout reconstruction segments.
- Discard state from rolled-back turns and treat compaction as a
baseline reset.
- Hydrate `ContextManager` from the reconstructed snapshot on resume and
fork.
- Remove the synthetic `TurnContextItem` to WorldState conversion path.
- Leave legacy or malformed rollouts without a baseline so the next
update safely emits a full snapshot.

## Testing

- `just test -p codex-core world_state`
- `just test -p codex-core rollout_reconstruction_tests`
- `just fix -p codex-core`
- `just test -p codex-core` *(the changed tests passed; the full run
also hit unrelated existing/test-environment failures, primarily a
missing `test_stdio_server` binary)*
## Why

MCP error-code telemetry special-cased Codex Apps: its reported error
codes were retained, while codes from every other MCP server were
replaced with `unknown`. Error reporting should behave consistently for
every MCP server. The server name already identifies where an error came
from, so telemetry does not need a separate Codex Apps classification.

This follows up on [openai#28976](openai#28976),
which introduced MCP error-code telemetry.

## What changed

- Add the MCP server name to call, duration, and error metrics.
- Retain bounded, sanitized tool error codes from every MCP server.
- Remove `McpErrorCodeSource` and the Codex Apps ownership lookup from
telemetry collection.
- Use the same metric-tagging path for blocked, rejected, and executed
MCP calls.

## Test plan

- Verify the complete metric tag set includes the sanitized MCP server
name.
- Verify error codes from ordinary MCP servers are retained, bounded,
and sanitized.
- Preserve coverage for request failures, tool-result failures, nested
auth failures, and span attributes.
## Why

Token-budget reminder and guidance messages can require more than 1,000
bytes to provide useful model-facing instructions. At the same time,
these strings are injected into model-visible context, so their size
must remain tightly bounded in response to the P0 context-growth
concern. A 2,000-byte runtime cap provides additional room without
allowing the substantially larger context growth of a 4 KiB limit.

## What changed

- raises the runtime byte limits for token-budget reminder templates and
guidance messages from 1,000 to 2,000
- raises the corresponding JSON Schema `maxLength` values to 2,000
- regenerates `codex-rs/core/config.schema.json`

## Testing

- `just test -p codex-features`
- `just test -p codex-core load_config_resolves_token_budget_config
load_config_rejects_invalid_token_budget_reminder_template`

The full `codex-core` test run completed 2,858 tests successfully and
encountered seven unrelated environment-sensitive failures involving
Seatbelt/network environment assertions, MCP capability setup, and abort
timing.
## Summary

- add a cancellable sleep operation to `TimeProvider`
- route `clock.sleep` through the configured provider
- extend the supported sleep duration to 12 hours
- complete the sleep turn item before propagating provider failures

## Why

This isolates the core clock abstraction needed by external clock
integrations. Existing system and app-server behavior remains wall-clock
based in this PR; the stacked follow-up supplies app-server sleeps from
an external clock.
## Stack

This is PR 3 of the simplified HAI single-run-task stack:

- [openai#19047](openai#19047) Agent Identity
assertion and task-registration primitives, including the shared
run-task helper used by existing Agent Identity JWT auth.
- [openai#19049](openai#19049)
Disabled-by-default ChatGPT auth opt-in that provisions/reuses persisted
Agent Identity runtime auth and its single run task.
- [openai#19051](openai#19051) Run-scoped
provider auth that uses one backend-owned task id for first-party
inference and compaction requests.

[openai#19054](openai#19054) collapsed out of
the active stack because the simplified design no longer needs a
separate background/control-plane task helper.

## Summary

This PR moves Agent Identity usage into provider auth resolution. That
keeps `AgentAssertion` auth tied to first-party OpenAI provider requests
instead of applying a late session-wide override that could affect
local, custom, Bedrock, API-key, or external-bearer providers.

What changed:

- adds a small `ProviderAuthScope` struct carrying the run auth policy
and session source needed by provider-scoped auth resolution
- lets `Session` opt the existing `ModelClient` into `ChatGptAuth`
policy when `use_agent_identity` is enabled, without adding a second
model-client constructor
- resolves Agent Identity only for first-party OpenAI provider auth
paths
- uses the persisted run task id from the `AgentIdentityAuth` record to
build `AgentAssertion` auth for Responses requests
- routes shared request setup through scoped provider auth so unary
compact requests use the same run-task assertion path as inference turns
- keeps local/custom/Bedrock/env-key/external-bearer provider auth
unchanged
- lets missing run-task state surface through the existing model-request
error path instead of silently falling back to bearer auth

This PR intentionally does not create thread-scoped, target-scoped, or
background-scoped task identities. The run task is the only task Codex
registers in this POC shape.

## Testing

- `just test -p codex-model-provider`
- `just test -p codex-core client::tests::provider_auth_scope_uses`
- `just test -p codex-core remote_compact_uses_agent_identity_assertion`
## Why

With deferred executors, a turn can begin before a remote environment
attaches. AGENTS.md discovery previously ran only during session setup,
so instructions from a later environment never reached the model or the
session instruction sources.

WorldState persistence has now landed, so this uses the durable
model-visible baseline directly instead of carrying a temporary
resume/fork compatibility path.

## What

- Add an `AgentsMdManager` in `SessionServices` to own host
instructions, loaded state, and refresh caching.
- When `DeferredExecutor` is enabled, refresh AGENTS.md when attached
environment selections change and freeze the result in the corresponding
`StepContext`.
- Represent AGENTS.md as a persisted WorldState section for every
session, with bounded initial, replacement, and removal updates.
- Remove duplicate AGENTS.md state and rendering from
`SessionConfiguration` and `TurnContext`.
- Build initial context, per-request updates, and compaction context
from the same step-scoped value.
- On resume and fork, compare current instructions with the restored
WorldState baseline and inject a replacement exactly once when they
differ.

Builds on openai#29833, openai#29835, and openai#29837.

## Tests

- Covers a remote environment becoming ready mid-turn, with AGENTS.md
appearing on the next request exactly once and updating canonical
instruction sources.
- Covers full, unchanged, replaced, and removed AGENTS.md WorldState
rendering.
- Covers changed instructions across cold resume and fork without
duplicate reinjection.
- Covers remote-v2 compaction retaining creation-time instructions in
the live session and cold resume appending one replacement when the
source changed.
- Ran focused `codex-core` AGENTS.md, WorldState, and context-update
test suites.
## Why

Older rollouts can retain model-visible context for a WorldState section
without having a persisted snapshot for that section. Treating the
missing snapshot as definitely absent can duplicate old context or fail
to tell the model that it was replaced or removed.

This provides a generic migration path for sections moving into
WorldState, beginning with AGENTS.md.

Builds on openai#29810.

## What changed

- distinguish section state that is absent, known from a persisted
snapshot, or unknown because matching legacy context remains in history
- let WorldState sections identify their own legacy fragments while
`ContextManager` owns history reconciliation and baseline persistence
- make AGENTS.md emit one conservative replacement or removal update for
legacy history, then deduplicate from the newly persisted baseline
- preserve existing environment rendering when persisted section data is
missing or malformed

## Testing

- `just test -p codex-core world_state`
- `just test -p codex-core
cold_resume_invalidates_deleted_legacy_agents_md_once -- --exact`
## Why

Avoid a request waterfall for loading lots of skills at once by hiding
latency in concurrent tasks.

## What changed

Poll the per-skill parse futures concurrently with an order-preserving
stream capped at 64 in-flight loads. Results retain discovery order, and
the existing filtering, warnings, and final catalog sorting are
unchanged.
## Why

Selected executor plugins can declare both stdio and Streamable HTTP MCP
servers, but only stdio registrations were retained. That silently drops
part of the plugin's tool surface and prevents HTTP traffic from using
the owning executor's network.

## What changed

- retain selected-plugin Streamable HTTP MCP declarations alongside
stdio declarations
- route their HTTP clients through the owning executor environment
- preserve local auth-header environment references while rejecting them
for executor-hosted declarations
- cover thread isolation, refresh, and an executor-only HTTP route end

## Description

This PR moves hook prompts onto the canonical `TurnItem` lifecycle in
core.

Stop hooks now record their `ResponseItem` through the existing
lifecycle path, which emits `ItemStarted` and `ItemCompleted`.
App-server consumes those events directly instead of deriving a hook
prompt from `RawResponseItem`.

## Why

Hook prompts were the only `ThreadItem` app-server synthesized from
`RawResponseItem`. This brings them in line with other core-owned turn
items while preserving legacy rollout replay.

## What changed

- Route stop-hook prompts through
`record_response_item_and_emit_turn_item`.
- Materialize canonical hook prompts in `ThreadHistoryBuilder`.
- Remove `RawResponseItem` to `ThreadItem` synthesis while preserving
legacy rollout replay.
- Add focused coverage for lifecycle emission and canonical and legacy
history materialization.
## Why

Amazon Bedrock's GPT-5.6 variants currently appear as only `Sol`,
`Terra`, and `Luna`. Those labels omit the model family and version,
making them ambiguous in model lists and inconsistent with the naming of
other GPT models.

## What changed

- Rename the three Bedrock model display names to `GPT-5.6 Sol`,
`GPT-5.6 Terra`, and `GPT-5.6 Luna`.
- Strengthen the Bedrock model-manager test to verify both model IDs and
their propagated display names.

Model IDs, ordering, priorities, reasoning support, and default
selection are unchanged.
## Description

This PR removes the last path in core that emits `ExecCommandBegin` /
`ExecCommandEnd` directly.

Every command execution now starts and completes through canonical
`ItemStarted` / `ItemCompleted(TurnItem::CommandExecution)`. The
existing `HasLegacyEvent` compatibility layer still fans out Begin/End
afterward, so raw core event consumers and legacy rollout replay keep
seeing the same events.

`UnifiedExecInteraction` is dormant today. Live unified exec uses
`UnifiedExecStartup` for command lifecycle and `TerminalInteraction` for
`write_stdin` and polling, so this is code cleanup rather than a current
product behavior change. The main win is the code-level invariant where
all core flows emit `TurnItem` instead of legacy events.

## What changed

- Removed the `UnifiedExecInteraction` branches that emitted legacy
command events directly.
- Routed every command source through the existing canonical
`CommandExecution` lifecycle and compatibility fanout.
## Why

Responses WebSockets are the normal lower-latency transport for
WebSocket-capable providers. They must not bypass an OS-selected proxy
when `features.respect_system_proxy` is enabled, but disabling
WebSockets whenever the feature is enabled would impose a substantial
performance penalty.

Merged PR openai#31622 introduced the reusable proxy-aware WebSocket
transport. This PR makes the Responses API its first consumer so the
existing fast path uses the same effective proxy and trust policy as
HTTP.

## What changed

- Register `codex-websocket-client` as a workspace dependency and use it
from `codex-api`.
- Feed the shared crate’s route-independent `WebSocketConnection` into
the existing Responses message pump.
- Require a configured `HttpClientFactory` for normal Responses
WebSocket connections and the CLI doctor probe, so neither path can open
a connection without consulting the effective proxy policy.
- Pass the session factory from `core` and the effective configuration
factory from `doctor`.
- Add an end-to-end Responses test that enables `RespectSystemProxy`,
asserts the resolved policy, completes a turn over WebSocket, and
verifies the connection and request counts.
- Keep the existing Responses protocol handling, ping/pong pump, and
session-scoped HTTP fallback unchanged.

The DNS, proxy, TLS, custom-CA, and Happy Eyeballs implementation and
its transport tests live in merged PR openai#31622. This PR deliberately
contains only the Responses integration and does not duplicate that
transport code.

## Review guide

1. `codex-rs/codex-api/src/endpoint/responses_websocket.rs` constructs
the shared connector and adapts its uniform stream to the existing pump.
2. `codex-rs/core/src/client.rs` supplies the session-scoped factory for
production Responses connections.
3. `codex-rs/cli/src/doctor.rs` supplies the effective configuration
factory to the handshake probe.
4. `codex-rs/core/tests/suite/client_websockets.rs` covers the
enabled-feature path end to end.

## Test plan

- `cargo check --tests -p codex-api -p codex-core -p codex-cli`
- `just test -p codex-api`
- `just test -p codex-core
responses_websocket_streams_with_system_proxy_feature`

## Why

Windows Cargo and Bazel jobs spend significant time in filesystem-heavy
build and cache directories. Route those directories through one CI
build root so Windows can use its Dev Drive and Unix can use a stable
cache root.

## What

- Have `setup-ci` define `CI_BUILD_ROOT`, `CARGO_TARGET_DIR`, Bazel
cache/output paths, and temp paths.
- Require Windows to find or provision a verified Dev Drive instead of
falling back to `C:`.
- Pass the shared Bazel output base to `setup-bazel` so its explicit
`output_base` does not defeat Dev Drive routing.
- Point nextest, release, and V8 source-build paths at the shared
environment contract.

## Benchmark results

One-off cold-cache WPR/ETW traces show the explicit Bazel output-base
routing removes the dominant `C:` traffic:

| sample | `C:\_bazel` | summed `C:` traffic | traced test step |
|---|---:|---:|---:|
| shard 1 before | 62.2 GiB | 85.2 GiB | 16m22s |
| shard 1 updated | 0 | 16.5 GiB | 12m05s |
| shard 3 before | 67.2 GiB | 84.6 GiB | 16m48s |
| shard 3 updated | 0 | 13.5 GiB | 11m08s |

For a cold x64 V8 source build, the retained build-tail sample showed
`D:\cargo-target` at ~1.29 GiB while measured `C:` roots totaled ~0.45
GiB (`C:\Users` ~0.33 GiB, `C:\Program Files` ~0.06 GiB, `C:\Windows`
~0.03 GiB). The full cold build took 2h20m36s.

The Bazel timing improvement is directional because both refreshed
shards failed tests. The V8 trace is a bounded build-tail sample, not
the full build. All final samples had zero lost ETW events; VHDX traffic
was excluded from the optimization ranking.

## Why

`codex-rs/.github/workflows/cargo-audit.yml` is nested below the
repository root, so GitHub Actions never discovers or runs it. RustSec
advisory enforcement already runs through the root `cargo-deny`
workflow.

## What

Remove the inert nested Cargo audit workflow.

## Validation

- Ran `git diff --check`.
- Verified the workflow is absent from GitHub registered workflows and
that root blocking CI invokes `cargo-deny`.
## Why

We should be running as many integrations tests as possible against the
split cross-OS configuration.

## What

- migrate eligible thread starts and builders to auto env
- keep explicit custom/local-executor cases local with rationale
comments
- keep auto-env coverage where possible and add narrow `TODO(anp)` skips
for fixtures that are not target-native yet
## Why

The 4,000-byte limit is compacting the tool schemas of some hero
usecases.

## What changed

Raise the limit to 5,000 bytes and update compaction test fixtures
accordingly.
### summary

We want to pause code-mode from yielding back to the model when a
subcommand triggers an approval prompt. This means that all of these
previously inline blocking requests should also take out a
ElicitationService registration.

This also does some plumbing refactoring to request patch approval to
make it match the other `request_*_approval` methods in that it blocks
on the approval in the function instead of returning the oneshot
channel, this affords our ability to encapsulate the ElicitationService
registration via RAII.

Adds tests to confirm the blocking behavior for code_mode both in suite
tests and that the session holds them.
## Why

The existing device-code warning does not help users distinguish a login
they initiated from a phishing attempt. The warning should tell users to
stop when the code came from a website or another person.

## What changed

- Updated the warning in the direct CLI and TUI device-code login flows
with actionable guidance.
- Added focused coverage for the styled direct CLI prompt.
## Why

Windows CI now places temporary and build files on the `D:` Dev Drive.
Fake rollout metadata still stored `/` as its working directory, but `/`
is drive-relative on Windows. When the migrated auto-environment tests
resumed or listed those rollouts, the fixture resolved to `D:\` while
the established test expectation remained `C:\`, causing unrelated PRs
to fail the Windows app-server shard.

This follows the interaction between openai#31357, which moved CI build paths
to the Dev Drive, and openai#31614, which migrated these app-server tests to
automatic environments.

## What

- Construct fake rollout working directories with `test_path_buf("/")`,
producing a fully qualified native path on Windows while preserving `/`
on Unix.
- Use the same native test-path helper for the legacy
conversation-summary expectation.

## How to Test

Automated tests were intentionally not run locally at request; the
app-server suite was stopped during compilation. `just fmt` completed
successfully.

To verify the regression on a Windows runner:

1. Configure `TEMP` and `TMP` on a non-`C:` drive, as CI does with the
Dev Drive.
2. Run `just test -p codex-app-server`.
3. Confirm the existing thread list, read, and resume tests no longer
report `D:\` actual versus `C:\` expected paths.

This is a test-fixture-only change, so there is no product smoke path.
## Summary

Codex Apps file parameters are exposed to the model as local paths,
uploaded at execution time, and rewritten into provided-file payloads
before the MCP tool call.

The rewrite currently forwards two internal upload fields, `uri` and
`file_size_bytes`, even though they are not part of the documented app
file-reference shape. Strict app schemas can reject those extra fields
before execution.

## Changes

- Stop copying `uri` and `file_size_bytes` into app-facing MCP
arguments.
- Keep the internal `UploadedOpenAiFile` result unchanged.
- Preserve the existing `download_url`, `file_id`, `mime_type`, and
`file_name` behavior for scalar and array file inputs.
- Verify the MCP invocation and post-tool hook receive exactly the
documented four-field payload against an `additionalProperties: false`
schema.

This intentionally does not add schema inspection or change how
`openai/fileParams` names are discovered.

## Validation

- `just test -p codex-core mcp_openai_file` (6 passed)
- `just test -p codex-core codex_apps_file_params_` (2 passed)
- `just fix -p codex-core`
- `just fmt`
- `git diff --check`
## Why
Auto-review performance is weaker because of confusing instructions
about sandbox permissions, and because it is given many tools which are
irrelevant to it.

## What
* Update the auto review prompt
* Remove the permissions_instructions developer message
* Only pass exec_tool and view_image tool to the reviewer

## Validation
`just fmt`
`cargo test -p codex-core --lib --quiet`
Automated update of models.json.

## Why

Macrobenchmarks benefit from having a way to exercise remote-executor
latency without depending on Docker.

This is a very minimal first cut, if we find that simulating network
conditions is useful we can always expand this scope or switch to a more
robust network shaping approach.

## What

- add a package-local exec-server binary for Cargo and Bazel test
fixtures
- add a host-local WebSocket exec-server fixture and fixed-delay
interposer
- let TestAppServer route its auto environment through that delayed
WebSocket transport
- cover the delayed thread/start path through the public app-server API

## Why

A thread resumed without an explicit reviewer could pick up the reviewer
from the current config instead of preserving the reviewer already in
use by the thread. After an app restart, this meant a thread running
with auto review could silently switch back to user review, and the next
turn could continue under the wrong reviewer.

## What changed

Persist the effective reviewer with each turn and restore the latest
persisted value when the thread resumes. If the resume request
explicitly provides a reviewer, that value still takes precedence.

## Test plan

- Added a regression test that starts a thread with auto review, records
a turn, restarts with user review in config, resumes without an
override, and verifies that auto review is preserved.

- `just test -p codex-state`
- `just test -p codex-rollout`
- `just test -p codex-app-server

- Clippy for the affected crates
The agent core team owns the core agent implementation and should review
changes to its adjacent runtime crates. Those crates were not covered by
the existing CODEOWNERS rules.

This adds `@openai/codex-core-agent-team` ownership for:

- `codex-rs/arg0`
- `codex-rs/codex-mcp`
- `codex-rs/exec-server`

## Validation

- `git diff --check`

No runtime tests are applicable because this only changes CODEOWNERS
metadata.
[Codex Thread
019f2408-dc59-79f2-b245-4c11debd1a61](https://codex-thread-link.openai.chatgpt-team.site/thread/019f2408-dc59-79f2-b245-4c11debd1a61)

## Why

Long-lived Codex sessions can outlive the ChatGPT bearer token that was
present when the MCP runtime started.

The Responses path already recovers from token expiration by refreshing
or reloading the shared `AuthManager`. The reserved `codex_apps`
hosted-plugin client did not observe that update: `McpConnectionManager`
built its `/ps/mcp` HTTP auth once from a `CodexAuth` snapshot, and
`auth_provider_from_auth` copied that snapshot bearer into a static
`BearerAuthProvider`.

After the copied bearer expired, `/ps/mcp` kept sending it even though
Responses had a newer token in the same `AuthManager`. The failure
occurred before downstream connector execution, so unrelated apps such
as Gmail, Slack, and Google Calendar could all fail with the same
transport-level `401 token_expired`.

This replaces
[openai#29474](openai#29474), which
was closed for inactivity without being merged. A new long-lived-session
report reproduced the same simultaneous `/ps/mcp` expiry pattern across
unrelated apps.

## What changed

- Add an `AuthManager`-backed request-header provider in
`codex-model-provider`. It keeps an `Arc<AuthManager>` and reads
`auth_cached()` for each outbound request, so the next `/ps/mcp` call
sees a token refreshed by the existing Responses/auth-recovery flow.
- Scope that provider to the startup account, ChatGPT user, and
workspace identity. Same-identity token reloads are followed; an account
switch emits no ambient auth until account-scoped MCP state is rebuilt.
- Have `McpConnectionManager` construct the dynamic provider only for
the reserved `codex_apps` registration used by the hosted-plugin
`/ps/mcp` path.

| MCP path | Auth behavior after this change |
| --- | --- |
| Reserved `codex_apps` hosted-plugin `/ps/mcp` | Read current
same-identity auth from the shared `AuthManager` per request |
| `codex_apps` with `CODEX_CONNECTORS_TOKEN` | Keep the environment
bearer-token override |
| User-configured/direct MCP registrations | Keep their existing
configured auth path |

## Non-goals

- No plugin-service changes.
- No downstream Slack, Gmail, Calendar, or other connector
OAuth/link-refresh changes.
- No auth UI changes.
- No behavior change for user-configured/direct MCP registrations.
- No new `/ps/mcp`-initiated token refresh; this makes `/ps/mcp` observe
refreshes already performed through the shared `AuthManager`.

## Tests

- `just test -p codex-model-provider`
- Covers same-identity token reloads and refuses a changed startup
identity.
- `just test -p codex-mcp`
- `just test -p codex-core mcp_auth_refresh`
- Creates the reserved hosted-plugin `codex_apps` `/ps/mcp` client
before the shared `AuthManager` changes, updates that same manager
through its public external-auth path, performs a real `tools/call`, and
asserts the request uses the current bearer.
…i#30188)

## Description

This PR makes new threads with `history_mode = "paginated"` persist
`ItemCompleted(item: <turn_item>)` in their rollout JSONL file.

Legacy threads keep persisting the existing legacy events. Because the
format is selected per thread, a rollout is either legacy or paginated;
we do not need to support mixed rollouts containing both
representations.

This PR depends on [openai#31473](openai#31473).

## Why

Paginated thread history needs stable turn/item IDs and completed item
snapshots so the later SQLite projector can materialize appended rollout
JSONL without rebuilding the whole thread.

Keeping the legacy persistence policy unchanged avoids changing
historical rollouts or the readers that still consume them.

## What changed

- Made rollout filtering history-mode aware. Paginated threads keep
completed canonical `ItemCompleted` events and drop their redundant
legacy projections; legacy threads keep the existing event set.
- Made forks inherit the source thread history mode, so copied legacy
history is never filtered as paginated.
- Made paginated threads assign IDs to locally-created response items
even when `Feature::ItemIds` is off, and reject streamed output items
that arrive without server IDs.
- Updated legacy turn replay, rollout list/search, and SQLite metadata
extraction to understand completed canonical user-message items.
Automated update of models.json.
