Keep local/default apply_patch review payloads from surfacing environment context, while still carrying non-local environment ids through Guardian and app-server review projections. Accept the remote approval snapshot shape emitted by the current TUI features.

Remove redundant clones in new apply_patch assertions, keep the Guardian TypeScript shape required-nullable instead of optional-nullable, and align the remote approval snapshot with the borrowed snapshot assertion.

Fix remote apply_patch hook environment reconciliation so malformed environment requests do not run hooks against the primary environment. Preserve local/default hook payload shapes, align Guardian app-server optionality, and surface remote approval cwd in the TUI.

## Why
We want terminal tool review analytics, but the reducer should not stamp
review timing from its own wall clock.
This PR plumbs review timing through the real protocol and app-server
seams so downstream analytics can consume the emitter's timestamps
directly. Guardian reviews keep their enriched `started_at` /
`completed_at` analytics fields by deriving those legacy second-based
values from the same protocol-native millisecond lifecycle timestamps,
rather than sampling a separate analytics clock.
## What changed
- add `started_at_ms` to user approval request payloads
- add `started_at_ms` / `completed_at_ms` to guardian review
notifications
- preserve Guardian review `started_at` / `completed_at` enrichment from
the protocol-native timing source
- stamp typed `ServerResponse` analytics facts with app-server-observed
`completed_at_ms`
- thread the new timing fields through core, protocol, app-server, TUI,
and analytics fixtures

## Why
Remote compaction v2 consumes a normal Responses stream, but that
compaction-specific stream consumer dropped the `response.completed` id.
As a result, the `responses_websocket_response_processed` lifecycle
notification was emitted for normal turn sampling but not after a v2
remote compaction response was fully processed.
## What changed
- Return the completed response id alongside the v2 `context_compaction`
output item.
- After v2 compacted history is installed, send `response.processed`
through the same websocket session when the feature is enabled.
- Add websocket regression coverage for a remote compaction v2 request
followed by `response.processed`.
## Verification
- `cargo test -p codex-core --test all

-- --nocapture`
- `cargo test -p codex-core
collect_context_compaction_output_accepts_additional_output_items --
--nocapture`
## Why
After stdio transports and provider-owned defaults exist, Codex needs a
config-backed provider that can describe more than the single legacy
`CODEX_EXEC_SERVER_URL` remote. This PR adds that provider without
activating it in product entrypoints yet, keeping parser/validation
review separate from runtime wiring.
**Stack position:** this is PR 4 of 5. It builds on PR 3's
provider/default model and adds the `environments.toml` provider used by
PR 5.
## What Changed
- Add `environment_toml.rs` as the TOML-specific home for parsing,
validation, and provider construction.
- Keep the TOML schema/provider structs private; the public constructor
added here is `EnvironmentManager::from_codex_home(...)`.
- Add `TomlEnvironmentProvider`, including validation for:
- reserved ids such as `local` and `none`
- duplicate ids
- unknown explicit defaults
- empty programs or URLs
- exactly one of `url` or `program` per configured environment
- Support websocket environments with `url = "ws://..."` / `wss://...`.
- Support stdio-command environments with `program = "..."`.
- Add helpers to load `environments.toml` from `CODEX_HOME`, but do not
wire entrypoints to call them yet.
- Add the `toml` dependency for parsing.

Route view_image through selected environments so image reads use the selected turn environment and cwd, with schema exposure limited to multi-environment toolsets.\n\nCo-authored-by: Codex <noreply@openai.com>
## Why
The next PR in this stack introduces configured environments, where the
provider knows both which environments exist and which one should be
selected by default. The existing manager derived the default internally
by checking for the legacy `remote` and `local` ids, and it treated
"remote" as equivalent to "has a websocket URL." That does not work
cleanly for stdio-command remotes because they are remote environments
without an `exec_server_url`.
**Stack position:** this is PR 3 of 5. It is the environment-model
bridge between PR 2's transport enum and PR 4's TOML provider.
## What Changed
- Add `DefaultEnvironmentSelection` to the `EnvironmentProvider`
contract:
- `Derived` preserves the old `remote`-then-`local` fallback behavior.
- `Environment(id)` lets a provider explicitly select a configured
default.
- `Disabled` lets a provider intentionally expose no default
environment.
- Move the legacy `CODEX_EXEC_SERVER_URL=none` default-disabling
behavior into `DefaultEnvironmentProvider`.
- Make `EnvironmentManager` validate explicit provider defaults and
return an error if the selected id is missing.
- Track `remote_transport` separately from `exec_server_url` so
stdio-command environments are still recognized as remote.
- Add `Environment::remote_stdio_shell_command(...)` for the TOML
provider added in the next PR.

Remove the remote thread-store backend and checked-in protobuf
artifacts. We've moved these into another crate that link against this
one.
Also remove the config settings for thread store backend selection,
since we'll instead pass an instantiated thread store into the core-api
crate's main entrypoint.
## Why
Configured environments need to connect to exec-server instances that
are not necessarily already listening on a websocket URL. A
command-backed stdio transport lets Codex start an exec-server process,
speak JSON-RPC over its stdio streams, and clean up that child process
with the client lifetime.
**Stack position:** this is PR 2 of 5. It builds on the server-side
stdio listener from PR 1 and provides the client transport used by later
environment/config PRs.
## What Changed
- Add `ExecServerTransport` variants for websocket URLs and stdio shell
commands.
- Add stdio command connection support for `ExecServerClient`.
- Move websocket/stdio transport setup into `client_transport.rs` so
`client.rs` stays focused on shared JSON-RPC client, session, HTTP, and
notification behavior.
- Tie stdio child process cleanup to the JSON-RPC connection lifetime
with a RAII lifetime guard.
- Keep existing websocket environment behavior by adapting URL-backed
remotes to `ExecServerTransport::WebSocketUrl`.

This adds 7-day cooldowns to all of our Dependabot ecosystem blocks. Our
Dependabot runs will continue at the same cadence as before, but the
scheduled PRs will no suggest updates that are fewer than 7 days old
themselves. This serves two purposes: to let dependencies "bake" for a
bit in terms of stability before we adopt them, and to give third-party
security services/tooling a chance to detect and revoke malware.
This should have no functional changes/consequences besides how rapidly
we get (non-security) updates. Dependabot security PRs can still be
scheduled and will bypass the cooldown.
Add Codex config for static trace span attributes and structured W3C
tracestate field upserts. The config flows through OtelSettings so
callers can attach trace metadata without touching every span call site.
Apply span attributes with an SDK span processor so every exported
trace span carries the configured metadata. Model tracestate as nested
member fields so configured keys can be upserted while unrelated
propagated state in the same member is preserved.
Validate configured tracestate before installing provider-global state,
including header-unsafe values the SDK does not reject by itself. This
keeps Codex from propagating malformed trace context from config.
Update the config schema, public docs, and OTLP loopback coverage for
config parsing, span export, propagation, and invalid-header rejection.
## Why
The goal of this PR is to align on app-server and `ThreadStore` API
updates for paginating through large threads.
#### app-server
##### `thread/turns/list`
- Updates `thread/turns/list` to support `itemsView?: "notLoaded" |
"summary" | "full" | null`, defaulting to `summary`.
- Implements the current `thread/turns/list` behavior over the existing
persisted rollout-history fallback:
- `notLoaded` returns turn envelopes with empty `items`.
- `summary` returns the first user message and final assistant message
when available.
- `full` preserves the existing full item behavior.
Note that this method still uses the naive approach of loading the
entire rollout file, and returns just the filtered slice of the data.
Real pagination will come later by leveraging SQLite.
##### `thread/turns/items/list`
- Adds the experimental `thread/turns/items/list` protocol, schema,
dispatcher, and processor stub. The app-server currently returns
JSON-RPC `-32601` with `thread/turns/items/list is not supported yet`.
#### ThreadStore
- Adds the experimental `thread/turns/items/list` protocol, schema,
dispatcher, and processor stub. The app-server currently returns
JSON-RPC `-32601` with `thread/turns/items/list is not supported yet`.
- Adds `ThreadStore` contract types and stubbed methods for listing
thread turns and listing items within a turn.
- Adds a typed `StoredTurnStatus` and `StoredTurnError` to avoid baking
app-server API enums or lossy string status values into the store-facing
turn contract.
- Adds a typed `StoredTurnStatus` and `StoredTurnError` to avoid baking
app-server API enums or lossy string status values into the store-facing
turn contract.
This also sketches the storage abstraction we expect to need once turns
are indexed/stored. In particular, `notLoaded` is useful only if
ThreadStore can eventually list turn metadata without loading every
persisted item for each turn.
## Validation
- Added/updated protocol serialization coverage for the new request and
response shapes.
- Added app-server integration coverage for `thread/turns/list` default
summary behavior and all three `itemsView` modes.
- Added app-server integration coverage that `thread/turns/items/list`
returns the expected unsupported JSON-RPC error when experimental APIs
are enabled.
- Added thread-store coverage that the default trait methods return
`ThreadStoreError::Unsupported`.
No developers.openai.com documentation update is needed for this
internal experimental app-server API surface.
## Summary
`cargo test` has entails both running standard Rust tests and doctests.
It turns out that the doctest discovery is fairly slow, and it's a cost
you pay even for crates that don't include any doctests.
This PR disables doctests with `doctest = false` for crates that lack
any doctests.
For the collection of crates below, this speeds up test execution by
>4x.

There's already a preference for this in the codebase, but a few of them
have drifted away. Generally `--locked` is preferred to reduce exposure
to supply-chain attacks (and just generally improve reproducibility).
In an ideal world these dependencies would maybe even be pinned to
versions but Cargo is kinda bad at that for devtools. Still better to
use --locked than not.
This builds on top of https://github.com/openai/codex/pull/15828 by
ensuring that hash-pinned actions with version comments are fully
qualified, rather than referencing floating/mutable comments like "v7".
This makes actions management tools behave more consistently.
This shouldn't break anything, since it's comment only. But if it does,
ping ww@ 🙂
A clean release build takes ~18m and an incremental build takes ~12m.
This is far too slow to iterate on performance related changes and the
build time is dominated by LTO.
This pull request adds a `profiling` profile for Cargo which takes ~13m
clean and ~6m incremental, the primary change is that LTO is disabled.
This matches a profile used in uv and follows the great work at
https://github.com/astral-sh/uv/pull/5955 — there's a bit of commentary
there about the trade-offs this implies.
We've found that this does not inhibit the ability to accurately
benchmark as measurements with LTO disabled are generally consistent
with the results with LTO enabled and it makes it much faster (~2x) to
rebuild after making a change.
This is motivated by my interest in improving Codex TUI performance,
which is blocked by the tragically builds right now.
I tested incremental build times by making a no-op change to the
`codex-cli` crate.
## Why
Codex desktop copies bundled Windows binaries out of `WindowsApps` into
a LocalAppData runtime cache before launching `codex.exe`. Sandboxed
commands can then need to execute helpers from that cache, but the
sandbox user group may not have read/execute access to the runtime bin
directory.
This makes the Windows sandbox refresh path repair that access directly
so the packaged desktop runtime remains usable from sandboxed sessions.
## What changed
- Added `setup_runtime_bin` to locate `%LOCALAPPDATA%\OpenAI\Codex\bin`,
matching the desktop bundled-binaries destination path, with the same
`USERPROFILE\AppData\Local` fallback shape.
- During refresh setup, check whether `CodexSandboxUsers` already has
read/execute access to the runtime bin directory.
- If access is missing, grant `CodexSandboxUsers` `OI/CI/RX` inheritance
on that directory.
- If the runtime bin directory does not exist, no-op cleanly.
## Verification
- `cargo build -p codex-windows-sandbox --bin
codex-windows-sandbox-setup`
- `cargo test -p codex-windows-sandbox --bin
codex-windows-sandbox-setup`
- Manual Windows ACL exercise against the installed packaged runtime
bin:
- existing inherited `CodexSandboxUsers:(I)(OI)(CI)(RX)` no-ops without
changing SDDL
- after disabling inheritance and removing the group ACE, setup adds
`CodexSandboxUsers:(OI)(CI)(RX)`
- with `LOCALAPPDATA` pointed at a fake location without
`OpenAI\Codex\bin`, setup exits successfully and does not create the
directory
- restored the real runtime bin with inherited ACLs and confirmed the
final SDDL matched the baseline exactly
- Route ThreadManager rollout-path resume/fork through ThreadStore
history reads.
- Add in-memory store coverage proving path-addressed reads are used.
This isn't strictly necessary for the ThreadStore migration, since these
ThreadManager methods _only_ work for path-based lookups, but I'm trying
to migrate all the rollout recorder callsites to use the threadstore
were possible for consistency.
## Summary
Fix `getConversationSummary` so thread-id summaries work for stored
threads that do not have a local rollout path, such as remote thread
stores.
The root cause was that `summary_from_stored_thread` returned `None`
when `StoredThread.rollout_path` was absent, and
`get_thread_summary_response_inner` treated that as an internal error.
This made conversation-id lookups depend on a local-only field even
though the thread store can address the thread by id.
- Route live thread renames through `ThreadStore` metadata updates.
- Read resumed thread names from store metadata with legacy local
fallback preserved in the store.
## Why
This is the next stacked step after deleting the tool-handler kind
indirection. Specs should come from the registered handlers themselves
so registry construction has a single source of truth for handler
behavior and exposed tool definitions.
## What changed
- Added `ToolHandler::spec()` plus handler-provided parallel/code-mode
metadata, and made `ToolRegistryBuilder::register_handler` automatically
collect specs from registered handlers.
- Moved builtin tool spec construction into the corresponding handlers
and their adjacent `_spec` modules, including shell, unified exec, apply
patch, view image, request plugin install, tool search, MCP resource,
goals, planning, permissions, agent jobs, and multi-agent tools.
- Reworked configurable handlers to receive their tool-building options
through constructors, with non-optional handler options where the
handler is always spec-backed. Shell fallback handlers keep an explicit
no-spec mode because they are also registered as hidden dispatch
aliases.
- Kept `CodeModeExecuteHandler` on the explicit configured wrapper so
the code-mode exec spec can still be built from the nested registry.
## Verification
- `cargo check -p codex-core`
- `cargo test -p codex-core tools::spec_plan::tests`
- `cargo test -p codex-core tools::spec::tests`
- `cargo test -p codex-core tools::handlers::multi_agents_spec::tests`
- `RUST_MIN_STACK=16777216 cargo test -p codex-core
tools::handlers::multi_agents::tests`
- `cargo test -p codex-core tools::handlers::apply_patch::tests`
- `cargo test -p codex-core tools::handlers::unified_exec::tests`
- `just fix -p codex-core`
- `git diff --check`
## Why
App-server config writes were leaving existing threads partially stale.
After a config mutation, the app-server told each live thread to run
`Op::ReloadUserConfig`, but that path only re-read the user
`config.toml` layer. Settings that came from the app-server's
materialized config snapshot did not propagate to existing threads until
restart.
This change prevent a FS access from `core` for CCA.
## What changed
- add `CodexThread::refresh_runtime_config()` and
`Session::refresh_runtime_config()` so the app-server can push a freshly
rebuilt config snapshot into a live thread
- rebuild the latest config with each thread's `cwd` after config
mutations, then refresh the thread from that snapshot instead of asking
it to reload only `config.toml`
- keep session-static settings unchanged during refresh, while updating
runtime-refreshable state such as the config layer stack,
`tool_suggest`, and derived hook/plugin/skill state
- keep `reload_user_config_layer()` as the file-backed fallback for
legacy local reload flows, but route the shared refresh logic through
the new runtime refresh path
## Testing
- add a session test that verifies `refresh_runtime_config()` rebuilds
hooks from refreshed config
- add a session test that verifies runtime-refreshable fields update
while session-static settings like `model` and `notify` stay unchanged

## Summary
`codex --enable remote_control app-server --listen off` is the current
way to start a headless, remote-controllable app-server, but it is hard
to remember and exposes implementation details.
This adds `codex remote-control` as a friendly top-level wrapper for
that flow. The command starts a foreground app-server with local
transports disabled and enables `remote_control` only for that
invocation.
## Changes
- Add a visible `codex remote-control` CLI subcommand.
- Launch app-server with `AppServerTransport::Off`.
- Append `features.remote_control=true` after root feature toggles so
the explicit command wins over `--disable remote_control`.
- Reject root `--remote` / `--remote-auth-token-env`, matching other
non-TUI subcommands.
- Add tests for parsing, launch defaults, override ordering, and remote
flag rejection.
## Verification
- `cargo test -p codex-cli`
- `just fix -p codex-cli`
## Summary
This PR removes the synthetic `HashMap<String, ToolInfo>` keys from MCP
tool discovery. `McpConnectionManager::list_all_tools()` now returns
normalized `Vec<ToolInfo>`, and downstream code derives identity from
`ToolInfo::canonical_tool_name()`.
The motivation is to keep model-visible tool identity on
`ToolName`/`ToolInfo` instead of parallel string map keys, so future
namespace changes do not have to preserve otherwise-unused lookup keys.
## Changes
- Rename the MCP normalization path from `qualify_tools` to
`normalize_tools_for_model` and return tool values directly.
- Flow MCP tool lists through connectors, plugin injection, router/spec
building, code mode, and tool search as vectors/slices.
- Keep direct/deferred subtraction local to `mcp_tool_exposure`, using
`ToolName` values.
- Update tests to compare `ToolName` instances where MCP identity
matters.
## Validation
- `cargo test -p codex-mcp test_normalize_tools`
- `cargo test -p codex-core mcp_tool_exposure`
- `cargo test -p codex-core
direct_mcp_tools_register_namespaced_handlers`
- `cargo test -p codex-core
search_tool_registers_namespaced_mcp_tool_aliases`
- `just fix -p codex-mcp`
- `just fix -p codex-core`
## Why
We want to emit terminal review analytics for tool-related approval
flows, but the event contract needs to exist before the reducer can
publish anything.
This PR is the schema-only slice for the Codex review event family.
## What changed
- add the `ReviewEvent` analytics envelope in
`codex-rs/analytics/src/events.rs`
- define the review subject kind, reviewer, trigger, terminal status,
and post-review resolution enums
- define the review event payload with thread, turn, item, lineage,
tool, and timing fields that the emitter stack will populate
## Verification
- stacked verification in dependent PRs: `cargo test -p codex-analytics
analytics_client_tests --manifest-path codex-rs/Cargo.toml`

## Why
Follow-up to #21180: turn diffs are operation-backed now, but a failed
`apply_patch` can still leave exact filesystem mutations behind. For
example, a move can write the destination file before failing to remove
the source. Treating the whole call as unknowable then drops a change
that Codex actually knows happened, so the emitted turn diff can drift
from the workspace.
## What changed
-
[`apply-patch`](f55724e027/codex-rs/apply-patch/src/lib.rs (L248-L345))
now returns `ApplyPatchFailure` with the exact committed prefix
accumulated before an error. If a write failure may already have mutated
the target, the delta is marked inexact instead of being reused blindly.
- Move handling now records the destination write before attempting
source removal, so a partially failed move can still report the
destination file that definitely landed
([code](f55724e027/codex-rs/apply-patch/src/lib.rs (L463-L521))).
-
[`ApplyPatchRuntime`](f55724e027/codex-rs/core/src/tools/runtimes/apply_patch.rs (L49-L67))
now accumulates committed deltas across attempts and forwards them even
when the visible tool result is failed or sandbox-denied ([runtime
path](f55724e027/codex-rs/core/src/tools/runtimes/apply_patch.rs (L223-L250)),
[event
path](f55724e027/codex-rs/core/src/tools/events.rs (L215-L225))).
- `TurnDiffTracker` now consumes committed exact deltas rather than only
fully successful patches; exact-empty failures leave the aggregate
unchanged, while inexact deltas still invalidate it.
## Verification
- Added a regression test covering a failed move that still emits the
committed destination diff:
[`apply_patch_failed_move_preserves_committed_destination_diff`](f55724e027/codex-rs/core/tests/suite/apply_patch_cli.rs (L1517-L1586)).
- Kept explicit coverage that an inexact delta clears the aggregate
instead of publishing a guessed diff:
[`apply_patch_clears_aggregated_diff_after_inexact_delta`](f55724e027/codex-rs/core/tests/suite/apply_patch_cli.rs (L1589-L1655)).

## Why
Feedback uploads already carry auth-derived context like
`chatgpt_user_id`, but they do not include the authenticated
workspace/account id. Adding `account_id` makes feedback triage easier
when a user can operate across multiple ChatGPT workspaces.
## What changed
- emit auth-derived `account_id` into feedback tags in `app-server`
before the feedback snapshot is uploaded
- preserve that tag through `codex-feedback` upload tag assembly
alongside the existing merge behavior for other tags
- extend `codex-feedback` coverage to assert that snapshot-derived
`account_id` is present in uploaded tags
## Verification
- `cargo test -p codex-feedback
upload_tags_include_client_tags_and_preserve_reserved_fields`
- `cargo test -p codex-app-server --lib feedback_processor`
## Summary
- replace filesystem-based turn diff tracking with an operation-backed
accumulator
- preserve enough verified apply_patch state to render move-overwrite
cases correctly
- keep the turn/diff/updated contract intact while removing remote-only
turn-diff test skips
This takes the assumption that no 3P services rely on the output format
of `apply_patch`
## Why
For the CCA file system isolation push

## DISCLAIMER
This is experimental and no production service must rely on this
## Why
Built-in MCPs are product-owned runtime capabilities, but they were
previously flattened into the same config-backed stdio path as
user-configured servers. That made them depend on a hidden `codex
builtin-mcp` re-exec path, exposed them through config-oriented CLI
flows, and erased distinctions the runtime needs to preserve—most
notably whether an MCP call should count as external context for
memory-mode pollution.
## What changed
- Model product-owned built-ins separately from config-backed MCP
servers via `BuiltinMcpServer` and `EffectiveMcpServer`.
- Launch built-ins in process through a reusable async transport instead
of the hidden `builtin-mcp` stdio subcommand.
- Keep config-oriented CLI operations such as `codex mcp
list/get/login/logout` scoped to configured servers, while merging
built-ins only into the effective runtime server set.
- Retain server metadata after launch so parallel-tool support and
context classification come from the live server set; built-in
`memories` is now classified as local Codex state rather than external
context.
## Test plan
- `cargo test -p codex-mcp`
- `cargo test -p codex-core --test suite
builtin_memories_mcp_call_does_not_mark_thread_memory_mode_polluted_when_configured`
