Stack split from #25708. Original PR intentionally left open. This first
PR adds the multi-agent runtime metadata types and catalog plumbing used
by the rest of the stack.
## Summary
- cache the global remote plugin catalog when remote plugin listing runs
and warm it during startup
- use the cached remote catalog in plugin install recommendations with
canonical `plugin@openai-curated-remote` ids
- reuse the session `PluginsManager` for plugin recommendations so
remote cache state is visible on the recommend path
- skip core installed-state verification for remote plugin install
suggestions while leaving local plugin and connector verification
unchanged
## Testing

## Summary
Enterprise users can have an effective monthly credit limit, but Codex
`/status` currently drops that metadata from the account-usage response.
This change adds the optional `spend_control.individual_limit`
projection to the existing rate-limit snapshot flow. The backend client
reads the monthly limit, app-server exposes it as `individualLimit`, and
the TUI renders a `Monthly credit limit` row through the existing
progress-bar renderer.
When the backend does not return an effective monthly limit, existing
rate-limit behavior is unchanged.
## Existing backend state
The account-usage backend already returns the effective monthly limit
and current usage together:
```json
{
"spend_control": {
"reached": false,
"individual_limit": {
"limit": "25000",
"used": "8000",
"remaining": "17000",
"used_percent": 32,
"remaining_percent": 68,
"reset_after_seconds": 86400,
"reset_at": 1778137680
}
}
}
```
Before this change, Codex projected rolling `primary` and `secondary`
windows plus `credits`. It ignored `spend_control.individual_limit`, so
app-server clients and `/status` could not render the monthly cap.
The updated flow is:
```text
account usage backend
-> backend-client reads spend_control.individual_limit
-> existing rate-limit snapshot carries optional individual_limit
-> app-server exposes optional individualLimit
-> TUI renders Monthly credit limit
```
## App-server contract
`account/rateLimits/read` and sparse `account/rateLimits/updated`
notifications now include an additive nullable
`rateLimits.individualLimit` field:
```json
{
"individualLimit": {
"limit": "25000",
"used": "8000",
"remainingPercent": 68,
"resetsAt": 1778137680
}
}
```
In an `account/rateLimits/read` response, `null` means no monthly limit
is available. `account/rateLimits/updated` remains a sparse rolling
notification: clients merge available values into their most recent
`account/rateLimits/read` snapshot or refetch. Nullable account metadata
in a rolling notification does not clear a previously observed value.
## Design decisions
- Extend the existing rate-limit snapshot instead of introducing a
separate request or wire-level update protocol.
- Keep the Codex projection narrow: `/status` needs the effective limit,
current usage, remaining percentage, and reset timestamp.
- Render the monthly row through the existing progress-bar renderer,
with one optional detail line for `8,000 of 25,000 credits used`.
- Keep the backend response optional so existing accounts and older
usage states preserve their current behavior.
- Preserve cached monthly metadata when sparse rolling notifications
omit it. Live account-usage reads remain authoritative and can clear a
removed limit.
## Visual evidence
```text
Monthly credit limit: [██████████████░░░░░░] 68% left (resets 07:08 on 7 May)
8,000 of 25,000 credits used
```
Snapshot:
`codex-rs/tui/src/status/snapshots/codex_tui__status__tests__status_snapshot_includes_enterprise_monthly_credit_limit.snap`
## Testing
Tests: generated app-server schema verification, protocol tests,
backend-client tests, app-server integration coverage, TUI snapshot
coverage, formatting, and workspace lint cleanup.
## Why
Remote control enrollment authorizes a desktop server, but app-server v2
did not expose the follow-up pairing operation needed to mint a
short-lived controller pairing artifact from that enrolled server.
Clients need a narrow RPC that starts pairing without exposing the
backend `serverId` or conflating pairing with websocket connection
state.
Issue: N/A; internal remote-control pairing API change.
## What Changed
Added experimental app-server v2 `remoteControl/pairing/start` with
`manualCode` input and `pairingCode`, nullable `manualPairingCode`,
`environmentId`, and Unix-seconds `expiresAt` output. The method
serializes under its own `global("remote-control-pairing")` scope and is
documented in `app-server/README.md`.
Extended the remote-control transport with private `/server/pair`
request/response types and normalized `pair_url` handling. Pairing uses
the current enrolled server bearer, refreshes that bearer when needed,
keeps backend `server_id` private, validates returned `server_id` and
`environment_id` against the current enrollment, and preserves backend
status/header/body context for failures and malformed responses.
Wired the request through `RemoteControlRequestProcessor` and
`MessageProcessor`, mapping unavailable/disabled pairing to
`invalid_request` and backend failures to internal errors.
## Verification
- `just test -p codex-app-server-transport`
- `just test -p codex-app-server
remote_control_pairing_start_returns_pairing_artifacts`
## Summary
- Moves the existing `codex-cloud-requirements` crate to
`codex-cloud-config`.
- Updates workspace dependencies and imports to the new crate name.
- Intentionally keeps runtime behavior unchanged: this still fetches the
legacy cloud requirements endpoint.
## Details
This PR exists to make the lineage obvious before the bundle migration.
GitHub should show the old `codex-rs/cloud-requirements/src/lib.rs`
implementation as moved to `codex-rs/cloud-config/src/lib.rs`, rather
than as unrelated new code.
The follow-up PR adapts this moved crate to the new config bundle API
and switches runtime consumers over.
## Summary
Remove the dead experimental `persistExtendedHistory` app-server flag
and collapse rollout persistence to the single policy app-server already
used.
## What Changed
- Removed `persistExtendedHistory` from v2 thread start/resume/fork
params and deleted its deprecation notice path.
- Removed the persistence-mode enums and plumbing through core, rollout,
and thread-store.
- Made rollout filtering mode-free, keeping the existing limited
persisted-history behavior.
## Test Plan
- `just write-app-server-schema`
- `cargo nextest run --no-fail-fast -p codex-app-server-protocol
schema_fixtures`
- `cargo nextest run --no-fail-fast -p codex-app-server
thread_shell_command_history_responses_exclude_persisted_command_executions`
- `cargo nextest run --no-fail-fast -p codex-rollout -p
codex-thread-store`
- final `rg` for removed flag/type names
## Why
Fixesopenai/codex#20944.
Desktop side chats are intentionally ephemeral and pathless. They can
still accept live turns while loaded, but after a reload there is no
persisted rollout to resume. In the reported failure mode, Desktop could
send `$CODEX_HOME` as the resume/fork path for one of these pathless
side chats.
`thread/resume` and `thread/fork` prefer an explicit `path` over
`threadId`, and rollout path lookup only checked that a candidate
existed. That let `$CODEX_HOME` pass as a rollout path, so the later
rollout reader tried to open a directory and surfaced the low-level `Is
a directory` error.
## What Changed
- Reject explicit rollout paths that resolve to a directory or other
non-file before attempting to read rollout history.
- Make `codex_rollout::existing_rollout_path` return only plain or
compressed rollout candidates that are actual files.
- Add an app-server regression test that creates an ephemeral fork, runs
a turn while the side thread is loaded, simulates reload, then verifies
both `thread/resume` and `thread/fork` reject `$CODEX_HOME` with `path
is a directory` instead of the OS-level directory-read error.
- Rebase over the `TestAppServer` rename and update the remaining stale
test harness call sites to use `TestAppServer` with `app_server` local
variables.
Relevant code:
- `thread-store/src/local/read_thread.rs` validates explicit rollout
paths before rollout reading:
https://github.com/openai/codex/blob/25b47c8f425d351aaba4baa955a8092064a1707b/codex-rs/thread-store/src/local/read_thread.rs#L146-L165
- `rollout/src/compression.rs` now requires file metadata for plain and
compressed rollout candidates:
https://github.com/openai/codex/blob/25b47c8f425d351aaba4baa955a8092064a1707b/codex-rs/rollout/src/compression.rs#L940-L950
- The repro test covers the pathless ephemeral side-chat reload case:
https://github.com/openai/codex/blob/25b47c8f425d351aaba4baa955a8092064a1707b/codex-rs/app-server/tests/suite/v2/thread_fork.rs#L774-L886
## Verification
- `just test -p codex-app-server
pathless_ephemeral_thread_rejects_codex_home_path_after_reload`
## Why
#25701 renamed the app-server test harness to `TestAppServer`, but it
raced with #25681, which added a new `plugin_list` test call site still
using the old `McpProcess` name. Once both changes met on `main`,
app-server test builds failed before running the suite because
`McpProcess` no longer exists in that scope.
This PR fixes that CI break by updating the remaining stale call site to
the renamed helper.
## What Changed
- Replaced the `McpProcess::new(...)` use in
`codex-rs/app-server/tests/suite/v2/plugin_list.rs` with
`TestAppServer::new(...)`.
- Renamed the local variable from `mcp` to `app_server` at the same call
site to match the helper rename.
Relevant code:
https://github.com/openai/codex/blob/aadd9c999b4e0789f7afb2b9b8cc43000bb47e86/codex-rs/app-server/tests/suite/v2/plugin_list.rs#L234-L246
## Verification
Not run locally; this is a compile fix for the app-server test harness
rename.
This PR brought to you via VS Code rather than Codex...
- opened `codex-rs/app-server/tests/common/mcp_process.rs`
- put the cursor on `McpServer`
- hit `F2` and renamed the symbol to `TestAppServer`
- went to the file tree
- hit enter and renamed `mcp_process.rs` to `test_app_server.rs`
- ran **Save All Files** from the Command Palette
- ran `just fmt`
The End
(Admittedly, most of the local variables for `TestAppServer` are still
named `mcp`, though.)
## Why
Guardian auto-review normally uses the provider-preferred review model
when one is available. Some parent models need model-catalog metadata to
select a different review model while keeping older `/models` payloads
compatible when that metadata is absent.
## What changed
- Added optional `ModelInfo::auto_review_model_override` metadata to the
public model payload as a review-model slug.
- Updated Guardian review model selection to prefer the catalog override
when present, while preserving the existing provider preferred-model
path and parent-model fallback when it is omitted.
- Added focused Guardian coverage for override and no-override model
selection.
- Added an `auto_review` core integration suite test that loads override
metadata from a remote model catalog path and asserts the strict
auto-review `/responses` request uses the catalog-selected review model.
- Updated existing `ModelInfo` fixtures and local catalog constructors
for the new optional field.

## Why
This PR
https://github.com/openai/codex/pull/24161#discussion_r3325692763
revealed a subagent data modeling issue, where we overloaded
`forked_from_id` to also mean `parent_thread_id`. That's incorrect since
guardian and review subagents can be a subagent and NOT fork the main
thread's history.
The solution here is to explicitly store a new `parent_thread_id` on
`SessionMeta`, alongside `forked_from_id` which already exists. While
we're at it, also expose it in the app-server protocol on the `Thread`
object.
A thread->subagent relationship and a fork of thread history are
orthogonal concepts.
## What Changed
- Added top-level `parent_thread_id` persistence on `SessionMeta` and
runtime/session plumbing through `SessionConfiguredEvent`,
`CodexSpawnArgs`, `SessionConfiguration`, `ThreadConfigSnapshot`,
`TurnContext`, and `ModelClient`.
- Made turn metadata, request headers, analytics, and subagent-start
events read the separate runtime/top-level parent field instead of
deriving general parent lineage from `SessionSource` or
`forked_from_thread_id`.
- Passed parent lineage separately at delegated subagent, review,
guardian, agent-job, and multi-agent spawn construction sites;
copied-history fork lineage remains derived only from `InitialHistory`.
- Persisted and exposed parent lineage through rollout/thread-store
projections and app-server v2 `Thread.parentThreadId`.
- Updated app-server README text and regenerated app-server schema
fixtures for the additive `parentThreadId` response field.
## Summary
PR 3 of 5 in the cloud-managed config client stack.
Adds enterprise-managed cloud config as a first-class config layer
source. The layer metadata is preserved through config loading,
diagnostics, debug output, hook attribution, and app-server protocol
surfaces.
## Details
- Enterprise-managed config becomes a normal config layer source with
backend-supplied `id` and display `name` attached for provenance.
- These layers are designed to behave like non-file managed config: they
can surface syntax/type diagnostics by layer name even though there is
no physical config file.
- Relative path settings are resolved from a stored config base so
cloud-delivered config remains consistent with existing MDM-delivered
config semantics.
- Hook attribution distinguishes config-delivered hooks from
requirements-delivered hooks via `HookSource::CloudManagedConfig`.
- This remains pull-based and snapshot-oriented; the PR adds layer
identity/diagnostics, not dynamic reload behavior.
## Validation
Validated through the targeted stack checks after rebasing onto current
`main`:
- Rust crate tests for
config/hooks/cloud-config/backend-client/app-server-protocol
- Filtered `codex-core` and `codex-app-server` `cloud_config_bundle`
tests
- Python generated-file contract test
- `cargo shear --deny-warnings`
- Targeted `argument-comment-lint` for config/hooks
## Summary
- Use normal directory loading for plugin install app metadata so
install avoids forced directory refresh while still loading metadata on
cold cache.
- Continue force-refreshing codex_apps tools for auth state.
- Add regression coverage that pre-warms the directory cache and asserts
install returns cached app metadata without extra directory requests.
## Validation

## Problem
Saved threads can already be archived through app-server RPCs, but the
command line did not expose direct archive or unarchive commands.
## Solution
Add `codex archive <thread>` and `codex unarchive <thread>`, resolving
UUIDs or exact thread names before calling the existing `thread/archive`
and `thread/unarchive` RPCs. The commands support scoped remote flags so
callers can target remote app-server endpoints when archiving or
unarchiving threads.
This also fixes a long-standing bug in `codex resume <thread id>` and
`codex fork <thread id>` that I found when testing the new commands.
These operations shouldn't be allowed on archived sessions. They now
fail with an error that tells the user to run `codex unarchive <thread
id>` first.
## Verification
Added app-server coverage for rejecting archived thread resume by id and
checking that the error includes the matching `codex unarchive <thread
id>` command.
# Why
Managed requirements can already constrain sandbox policy choices, but
Windows sandbox implementation selection was still resolved
independently from those requirements. That left the TUI able to
continue through the unelevated fallback even when an organization wants
to require the elevated Windows sandbox implementation.
# What
- Add `[windows].allowed_sandbox_implementations` requirements support
for the Windows `elevated` and `unelevated` implementations.
- Apply that allowlist during core config resolution so disallowed
configured or feature-selected Windows sandbox implementations fall back
to an allowed implementation with the existing requirements warning
path.
- Reuse the existing TUI Windows setup prompts to block disallowed
unelevated continuation, keep required elevated setup in front of the
user, and refuse to persist a TUI-selected Windows sandbox mode that
requirements disallow.
# Semantics
| Allowed | Selected | Effective |
| --- | --- | --- |
| `["elevated"]` | `unelevated` / unset | `elevated` |
| `["unelevated"]` | `elevated` / unset | `unelevated` |
| `["elevated", "unelevated"]` | `elevated` | `elevated` |
| `["elevated", "unelevated"]` | `unelevated` | `unelevated` |
| `["elevated", "unelevated"]` | unset | `elevated` |
Availability is handled by interactive setup surfaces after allowlist
resolution. If the effective elevated implementation is not ready,
elevated-only requirements block on setup. When unelevated is also
allowed, the UI may offer the existing unelevated fallback.
## TUI Screens
If elevated setup is not already complete:
```
Your organization requires the default Codex agent sandbox to continue. Set it up to protect your files and control
network access.
Learn more <https://developers.openai.com/codex/windows>
› 1. Set up default sandbox (requires Administrator permissions)
2. Quit
```
If admin setup fails under `["elevated"]`:
```
Couldn't set up your sandbox with Administrator permissions
Your organization requires the default sandbox before Codex can continue.
Learn more <https://developers.openai.com/codex/windows>
› 1. Try setting up admin sandbox again
2. Quit
```
# Next Steps
- extend the requirements/readout surface, such as
`configRequirements/read`, so clients can inspect the loaded
`[windows].allowed_sandbox_implementations` requirement instead of
inferring it from Windows setup state
- consider extending `windowsSandbox/readiness` as well
- update the App startup guide, setup flow, and banner surfaces so an
elevated-only requirement omits any continue-unelevated escape hatch and
blocks startup until a permitted implementation is ready;
- preserve the existing unelevated fallback path when requirements allow
it, including the `["unelevated"]` case where elevated is disallowed
## Why
The standalone `/v1/alpha/search` request now requires a `model`, but
the `web.run` extension currently omits it.
Adds `model` to extension `ToolCall` invocation.
Follow-up to #23823.
## What changed
- Make `SearchRequest.model` required.
- Expose the effective per-turn model on extension tool calls and pass
it in standalone web-search requests.
- Assert the model is forwarded in the app-server round-trip test.
## Testing
- `just test -p codex-api -p codex-tools -p codex-web-search-extension
-p codex-memories-extension -p codex-goal-extension`
- `just test -p codex-core -E
'test(passes_turn_fields_and_scoped_turn_item_emitter_to_extension_call)'`
- `just test -p codex-app-server -E
'test(standalone_web_search_round_trips_encrypted_output)'`
## Why
`SandboxPolicy` is the legacy compatibility shape, but
`codex-thread-store` still exposed it through `StoredThread`,
`ThreadMetadataPatch`, and live metadata sync. That kept thread-store
consumers tied to the legacy representation and meant richer permission
profile data could not round-trip through thread metadata or cold
rollout reconciliation.
## What Changed
- Replaced thread-store `sandbox_policy` API fields with canonical
`PermissionProfile` fields.
- Persist new permission-profile metadata as canonical JSON in the
existing SQLite metadata slot while continuing to read older legacy
sandbox policy values.
- Updated local, in-memory, live metadata sync, and rollout extraction
paths to propagate `TurnContextItem::permission_profile()`.
- Re-materialize legacy permission metadata against the final rollout
cwd when rollout-derived metadata replaces stale SQLite summaries.
- Updated affected app-server and core test constructors to build
`PermissionProfile` values directly.
## Test Plan
- `cargo test -p codex-state`
- `cargo test -p codex-thread-store`
- `cargo test -p codex-app-server
summary_from_stored_thread_preserves_millisecond_precision --lib`
- `cargo test -p codex-core realtime_context --lib`
## Why
We recently added `forked_from_thread_id` which lets us trace where a
thread's _context_ comes from, but we also want to understand subagent
lineage (e.g. which parent thread spawned this subagent? what kind of
subagent is it?) which is orthogonal.
This PR adds `parent_thread_id` and `subagent_kind` to the
`x-codex-turn-metadata` header sent to ResponsesAPI.
## What changed
- Adds `parent_thread_id` and `subagent_kind` to core-owned
`x-codex-turn-metadata`.
- Restores persisted `SessionSource` and `ThreadSource` from resumed
session metadata so cold-resumed subagent threads keep their lineage on
later Responses API requests.
- Centralizes parent-thread extraction on `SessionSource` /
`SubAgentSource` and reuses it in the Responses client, analytics, agent
control, and state parsing paths.
- Extends reserved-key, git-enrichment, thread-spawn, and app-server v2
metadata coverage for the new lineage fields.
## Verification
- Not run locally per request.
- Added focused coverage in `core/src/turn_metadata_tests.rs` and
`app-server/tests/suite/v2/client_metadata.rs`.
## Why
Standalone `web.run` calls run in the extension, so they need normal
web-search progress activity while a request is in flight and durable
completed activity after a thread is reloaded.
Follow-up to #23823; uses the extension turn-item emission path added in
#24813.
## What changed
- Emit standalone `web.run` start/completion items through the host
turn-item emitter, preserving standard client delivery and rollout
persistence.
- Include useful completion detail for queries, image queries, and
literal-URL `open`/`find` commands.
- Render completed searches as `Searched the web` or `Searched the web
for <detail>`, with snapshot coverage for the detail-free case.
- Extend the app-server round-trip test to verify completed search
activity is reconstructed by `thread/read` after a fresh-process reload.
## Testing
- `just test -p codex-web-search-extension`
- `just test -p codex-app-server -E
"test(standalone_web_search_round_trips_encrypted_output)"`
## Why
Some models need to select their code-execution behavior through model
catalog metadata. Models without that metadata must continue to follow
the existing `CodeMode` and `CodeModeOnly` feature flags, including when
a newer server sends an enum value this client does not recognize.
## What changed
- add optional `ModelInfo.tool_mode` metadata with `direct`,
`code_mode`, and `code_mode_only`
- treat omitted and unknown wire values as `None`
- resolve `None` from the existing feature flags
- carry the resolved `ToolMode` directly on `TurnContext`, outside
`Config`
- use the resolved value for turn creation, model switches, review
turns, tool planning, and code execution
## Coverage
- add protocol coverage for omitted, known, and unknown enum values
- add focused coverage for flag fallback and explicit metadata
overriding feature flags
- add core integration coverage that fetches remote model metadata
through `/v1/models` and verifies the outbound `/responses` tools for
explicit `direct` and `code_mode_only` selectors
## Stack
- followed by #25032
## Summary
`fs/watch` was using a local debounce wrapper whose deadline was
initialized once and then reused after the first batch. Once that stale
deadline was in the past, later file changes could bypass the intended
200ms debounce and send noisier `fs/changed` notifications.
This moves the debounce wrapper into `codex-file-watcher` as
`DebouncedWatchReceiver`, resets the debounce deadline for each event
batch, preserves pending paths across cancelled receives, and updates
app-server `fs/watch` to use the shared wrapper.
Fixes#24692.
## Why
#23813 switches the Windows sandbox runner path to `PermissionProfile`,
but it still left one runtime anchor for resolving symbolic
`:workspace_roots` entries. That is not enough once a turn has multiple
effective workspace roots: exact entries and deny globs under
`:workspace_roots` need to be materialized for every runtime root before
the command runner chooses token mode or builds ACL plans.
## What Changed
- Replaces the Windows runner/setup `permission_profile_cwd` plumbing
with `workspace_roots: Vec<AbsolutePathBuf>`.
- Resolves Windows-local `PermissionProfile` data with
`materialize_project_roots_with_workspace_roots(...)` instead of the
single-cwd helper.
- Threads `Config::effective_workspace_roots()` through core execution,
unified exec, TUI setup/read-grant flows, app-server setup, app-server
`command/exec`, and `debug sandbox` on Windows.
- Preserves those workspace roots through the zsh-fork escalation
executor instead of rebuilding them from `sandbox_policy_cwd`.
- Makes `ExecRequest::new(...)` and the remaining
`build_exec_request(...)` helper path take
`windows_sandbox_workspace_roots` explicitly so new call sites cannot
silently fall back to `vec![cwd]`.
- Clarifies the `debug sandbox` non-Windows comment: remaining
cwd-dependent resolution still uses `sandbox_policy_cwd`, while
`:workspace_roots` entries are already materialized from config roots.
- Updates elevated runner IPC `SpawnRequest` to send `workspace_roots`
and bumps the framed IPC protocol version to `3` for the payload shape
change.
- Adds Windows-local resolver coverage for expanding exact and glob
`:workspace_roots` entries across multiple roots, plus core helper
coverage proving explicit roots are preserved.

## Summary
Adds an optional `clientId` field to app-server v2 `UserInput` and
carries it through the core `UserInput` model so clients can correlate
echoed user input items without relying on payload equality.
## Details
- Adds `client_id: Option<String>` to core `UserInput` variants.
- Exposes the v2 app-server field as `clientId` on the wire and in
generated TypeScript.
- Preserves the id when converting between app-server v2 and core
protocol types.
- Regenerates app-server schema fixtures.

- `just fix -p codex-protocol`
- `git diff --check`
## Summary
- Add `--stdio` as a direct alias for `codex app-server --listen
stdio://`.
- Keep `--stdio` and `--listen` mutually exclusive.
- Update the app-server README to document both forms.
## Why
Add a standalone image generation path that can be exercised
independently of hosted Responses image generation, while retaining the
hosted tool as fallback unless the extension is actually available to
the model.
## What changed
- Added the `codex-image-generation-extension` crate with standalone
generate/edit execution, prior-image selection for edits, model-visible
image output, and local generated-image persistence.
- Installed the extension in app-server behind the disabled-by-default
`imagegenext` feature and backend eligibility checks.
- Updated core tool planning so eligible `image_gen.imagegen` exposure
replaces hosted `image_generation`, while unavailable configurations
retain hosted fallback.
- Added coverage for extension behavior, edit history reuse, feature
gating, auth eligibility, and hosted-tool replacement.
- The extension is installed through app-server only in this PR; other
execution paths retain hosted image generation because hosted
replacement occurs only when the standalone executor is actually
registered and model-visible.
- The initial extension contract intentionally fixes the image model to
`gpt-image-2` and uses automatic image parameters.
- Native generated-image history/card parity and rollout persistence
cleanup are intentionally deferred follow-up work.

## Summary
The client currently calls `thread/resume` to establish live updates and
immediately follows it with `thread/turns/list` to hydrate recent turns.
This lets `thread/resume` return that page directly, eliminating a round
trip and the ordering/deduplication gap between the two calls.
Experimental clients opt in with `initialTurnsPage: { limit,
sortDirection, itemsView }`. The response returns `initialTurnsPage` as
a `TurnsPage`, including cursors for paging further back in history.
Keeping the controls in a nested opt-in object provides the useful
`thread/turns/list` knobs without spreading page-specific parameters
across `thread/resume`.

## Why
Config loading should not create or write-authorize the memories root
just because memory support exists. Memory startup is the code path that
actually materializes that tree.
## What
- Stop creating the memories root during Config load and remove it from
legacy workspace-write projections.
- Grant the memories root read access only when the memories feature and
use_memories are enabled.
- Create the memories root inside memories startup before seeding
extension instructions.
- Update config and startup tests around the ownership boundary.

Note: a broader just test -p codex-core run is not clean in this
sandbox; it hit missing test_stdio_server plus seatbelt, realtime, and
environment-sensitive failures. The changed config tests above pass.
WIll make it easier to uprev when the new draft spec is supported.
Also updates reqwest where needed for compatibility but doesn't update
it everywhere since this is already a large diff.
The new version of rmcp handles certain kinds of authentication failures
differently, this patch includes support for identifying the failing scope
in a WWW-Authenticate header.
Client-side namespace tools are now supported by bedrock. Enable
`namespace_tools` for the Amazon Bedrock provider while continuing to
disable unsupported hosted tools such as image generation and web
search.
## Summary
- Add `request_kind` values for foreground turn, startup prewarm,
compaction, and detached memory model requests.
- Attach compaction dispatch metadata to local Responses, legacy
`/v1/responses/compact`, and remote v2 compact requests.
- Add the existing logical context-window identifier as `window_id` on
turn-owned model request metadata.
- Keep identity fields optional for detached memory requests, while
still emitting `request_kind="memory"` in non-git/no-sandbox workspaces.
## Root Cause
`x-codex-turn-metadata` has more than one producer. Foreground turns and
compaction requests own a real turn and should carry that turn identity.
Detached memory stage-one requests do not own a foreground turn, so
absent identity fields are valid rather than missing data. Startup
websocket prewarm is also a model request, but it has `generate=false`
and must not be counted as a foreground turn.
`thread_source` or session source identifies where a thread came from
(for example review, guardian, or another subagent). `request_kind`
identifies what the current outbound model request is doing (`turn`,
`prewarm`, `compaction`, or `memory`). A review or guardian thread can
issue either a normal turn request or a compaction request, so source
cannot replace request kind.
## Behavior / Impact
- Ordinary foreground requests send `request_kind="turn"`, their real
identity fields, and `window_id="<thread_id>:<window_generation>"`.
- Startup websocket warmup requests send `request_kind="prewarm"` so
they are not counted as foreground turns.
- Compaction requests send `request_kind="compaction"`, their real
owning turn identity, the existing `window_id`, and
`compaction.{trigger,reason,implementation,phase,strategy}`.
- Detached memory stage-one requests send `request_kind="memory"`
without `session_id`, `thread_id`, `turn_id`, or `window_id`; when no
workspace metadata exists, the kind-only header is still emitted.
- `session_id`, `thread_id`, `turn_id`, and `window_id` remain optional
in the header schema because detached memory requests do not own a
foreground turn or context window.
- `window_id` is not a new ID system: it is copied from the already-sent
`x-codex-window-id` / WS client metadata value at model-request dispatch
time.
- Existing `x-codex-window-id` HTTP/WS emission, value format,
generation advancement, resume behavior, and fork reset behavior are
unchanged.
- `request_kind`, `window_id`, and upstream turn-owned identity fields
remain schema-owned; input `responsesapi_client_metadata` cannot replace
their canonical values.
- No table, DAG, export, app-server API, or MCP `_meta` schema changes
are included.
A compaction attempt stopped by a pre-compact hook issues no model
request and therefore has no request header; its outcome remains in
analytics events. Status, error, duration, and token deltas also remain
analytics fields rather than request-header fields.
Future detached-memory attribution using a real initiating turn ID as
`trigger_turn_id` is intentionally not part of this PR.
## Sync With Main
- Final pushed head `716342e79` is rebased onto `origin/main@0d37db4b2`.
- The metadata conflict came from upstream `#24160`, which added
`forked_from_thread_id` on the same `turn_metadata` surface. Resolution
preserves that field and its protection from client metadata override
alongside this PR's request-kind, compaction, and window-id fields.
- While resolving the overlapping commits, I removed an accidental
recursive model-request overlay and a duplicate detached-memory header
builder before completing the rebase.
## Latency / User Experience Boundary
- Foreground turns perform no new filesystem, git, or network work. New
fields are inserted into metadata already serialized for outgoing
requests.
- Compaction issues the same model/HTTP requests with the same prompt,
model, service tier, and sampling settings; only metadata bytes change.
- Startup prewarm already sent metadata; it is now correctly classified
as `prewarm`.
- Non-git detached memory now sends a small kind-only metadata header
rather than no header.
- This client diff adds no user-visible latency mechanism beyond
negligible serialization and header bytes on already-existing requests.

## Summary
- Bump the workspace Rust toolchain from `1.93.0` to `1.95.0` across
Cargo, Bazel, CI, release workflows, devcontainers, and the Codex
environment config.
- Refresh `MODULE.bazel.lock` so the Bazel Rust toolchain artifacts
match the new version.
- Leave purpose-specific toolchains unchanged, including the
`argument-comment-lint` nightly and the upstream `rusty_v8` `1.91.0`
build pin.
- Includes fixes for new lints from `just fix` and a few codex-authored
fixes for lints without a suggestion.
add new `parse_tool_input_schema_without_compaction` to bypass the
existing compaction/trimming of client-provided tool schemas that are
over 4k bytes.
we want this for standalone web search to keep field guidance/metadata
on certain fields; this keeps us closer to parity with existing hosted
tool schema (which didnt go through this 4k byte filter).
## Why
- Runtime analytics events report `thread_id`, which identifies the
individual thread emitting an event
- They don't report `session_id`, which identifies the shared session
for a root thread and its subagent threads
- Emitting both identifiers allows analytics to group related activity
## What Changed
- Adds `session_id` to relevant analytics events (thread_initalized,
turn, turn_steer, compaction, guardian_review)
- Tracks each thread's session ID in the analytics reducer so subsequent
thread scoped events emit the same value
- Carries the shared session ID through subagent initialization
## Verification
- `just test -p codex-analytics` validates event payloads and subagent
session grouping.
- Focused `codex-app-server` tests validate session IDs for thread,
turn, and steer events.
- Focused `codex-core` tests validate root and subagent session ID
propagation.
## Why
Windows sandbox diagnostics are currently hard to recover from
`/feedback` even though they are often the most useful artifact when
debugging sandbox behavior. Now that sandbox logging uses daily rolling
files, feedback can safely include the current day's sandbox log without
uploading the old ever-growing legacy `sandbox.log`.
## What changed
- Add a `codex-windows-sandbox` helper that resolves the current daily
sandbox log from `codex_home`.
- When feedback is submitted with logs enabled on Windows, app-server
attaches today's sandbox log if it exists.
- Upload the attachment under the stable filename `windows-sandbox.log`,
independent of the dated on-disk filename.
- Keep existing raw `extra_log_files` behavior unchanged for rollout and
desktop log attachments.
## Verification
- `cargo fmt -p codex-app-server -p codex-windows-sandbox`
- `cargo test -p codex-windows-sandbox
current_log_file_path_for_codex_home_uses_sandbox_dir`
- `cargo test -p codex-app-server
windows_sandbox_log_attachment_uses_current_log`
- Manual CLI/TUI `/feedback` test confirmed Sentry received
`windows-sandbox.log`.
## Why
The Windows sandbox runner still carried the old `SandboxPolicy`
compatibility path even though core now computes `PermissionProfile`.
That meant Windows command-runner execution could only see the legacy
projection, so profile-only filesystem rules such as deny globs were not
part of the runner input.
## What Changed
- Removed the Windows-local `SandboxPolicy` parser/export and deleted
`windows-sandbox-rs/src/policy.rs`.
- Changed restricted-token capture/session setup, elevated setup,
world-writable audit, read-root grant, and command-runner session APIs
to accept `PermissionProfile` plus the profile cwd.
- Bumped the elevated command-runner IPC protocol to version 2 because
`SpawnRequest` now carries `permission_profile` /
`permission_profile_cwd` instead of the legacy `policy_json_or_preset` /
`sandbox_policy_cwd` fields.
- Updated core exec, unified exec, debug-sandbox, TUI setup/grant flows,
and app-server setup to pass the actual effective `PermissionProfile`.
- Left regression coverage asserting the old IPC policy fields are
absent and the runner serializes tagged `PermissionProfile` JSON.
## Verification
- `cargo test -p codex-windows-sandbox`
- `cargo test -p codex-core windows_sandbox`
- `cargo test -p codex-app-server
request_processors::windows_sandbox_processor`
- `just fix -p codex-windows-sandbox -p codex-core -p codex-app-server
-p codex-cli -p codex-tui`
- `just fix -p codex-cli -p codex-tui`
- `just fix -p codex-windows-sandbox -p codex-tui`
- `rg "\\bSandboxPolicy\\b" codex-rs/windows-sandbox-rs` returned no
matches.
Note: `cargo test -p codex-cli` was attempted but did not reach crate
tests because local disk filled while compiling dependencies (`No space
left on device`). The targeted clippy pass compiled the affected CLI/TUI
surfaces afterward.

* __->__ #23813
## Why
When Codex calls responsesapi, we currently send `session_id`,
`thread_id`, and `turn_id` among other things as
`client_metadata["x-codex-turn-metadata"]`. This PR adds
`forked_from_thread_id` which helps explain the "lineage" of a forked
thread.
## What's changed
- Track the immediate history source copied into a forked thread through
thread/session creation, including subagent and review turn metadata
paths.
- Include `forked_from_thread_id` in Codex turn metadata while
preventing turn-scoped Responses API client metadata from overwriting
Codex-owned lineage fields.
- Add coverage for fork lineage in turn metadata and the app-server
Responses API request path.
Fixes#24186.
## Why
When the TUI resumes a thread through the local app-server daemon with a
selected workspace, `thread/resume` can hit an already-loaded but idle
cached thread. That path previously rejoined the cached `CodexThread`,
so cwd/config overrides in `ThreadResumeParams` were ignored and the
resumed session kept using the old cwd.
## What changed
App-server now treats a loaded-but-idle thread with no subscribers as a
cache entry when resume overrides differ: it unloads that cached thread
and lets the normal resume path rebuild it with the requested
cwd/config. Threads that still have subscribers, or active runtime work,
continue to rejoin the existing loaded thread so in-flight state remains
observable.
The existing thread teardown helper was generalized from
archive-specific cleanup to shared unload cleanup for this path.
## Summary
Adds experimental `additionalContext` support to `turn/start` and
`turn/steer` so clients can provide ephemeral external context, such as
browser or automation state, without turning that plumbing into a
visible user prompt or triggering user-prompt lifecycle behavior.
## API Shape
The parameter shape is:
```ts
additionalContext?: Record<string, {
value: string
kind: "untrusted" | "application"
}> | null
```
Example:
```json
{
"additionalContext": {
"browser_info": {
"value": "Active tab is CI failures.",
"kind": "untrusted"
},
"automation_info": {
"value": "CI rerun is in progress.",
"kind": "application"
}
}
}
```
The keys are opaque and caller-defined.
## Context Injection
When provided, accepted entries are inserted into model context as
hidden contextual message items, not as visible thread user-message
items.
`kind: "untrusted"` entries are inserted with role `user`:
```text
<external_${key}>${value}</external_${key}>
```
`kind: "application"` entries are inserted with role `developer`:
```text
<${key}>${value}</${key}>
```
Values are not escaped. Each value is truncated to 1k approximate tokens
before wrapping.
For `turn/start`, accepted additional context is inserted before normal
user input. For `turn/steer`, additional context is merged only when the
steer includes non-empty user input; context-only steers still reject as
empty input.
## Dedupe Strategy
`AdditionalContextStore` lives on session state and stores the latest
complete additional-context map.
Each `turn/start` or non-empty `turn/steer` treats its
`additionalContext` as the current complete set of values. Entries are
injected only when the key is new or the exact entry for that key
changed, including `value` or `kind`. After merging, the store is
replaced with the provided map, so omitted keys are removed from the
retained set and can be injected again later if reintroduced.
Omitting `additionalContext`, passing `null`, or passing an empty object
resets the store to empty and injects nothing.
## What Changed
- Threads experimental v2 `additionalContext` through app-server into
core turn start and steer handling.
- Adds separate contextual fragment types for untrusted user-role
context and application developer-role context.
- Uses pending response input items so additional context can be
combined with normal user input without treating it as prompt text.
- Adds integration coverage for start/steer flow, role routing,
dedupe/reset behavior, deletion/re-add behavior, hook-blocked input
behavior, empty context-only steer rejection, external-fragment marker
matching, and truncation.
## Summary
Add the extension-backed standalone `web.run` tool so Codex can call the
standalone search endpoint through the `codex-api` search client and
return its encrypted output to Responses.
- gate the new tool behind `standalone_web_search`
- install the extension in the app-server thread registry and hide
hosted `web_search` when standalone search is enabled for OpenAI
providers so the two paths stay mutually exclusive
- build search context from persisted history using a small tail
heuristic: previous user message, assistant text between the last two
user turns capped at about 1k tokens, and current user message
## Test Plan
- `cargo test -p codex-web-search-extension`
- `cargo test -p codex-api`
- `cargo test -p codex-core
hosted_tools_follow_provider_auth_model_and_config_gates`
## Summary
Generated memory rows and their stage-one/stage-two job state currently
live in `state_5.sqlite` alongside thread metadata. That makes memory
cleanup and regeneration share the main state schema even though those
rows are memory-pipeline data and can be rebuilt independently from the
durable thread records.
This PR moves the memory-owned tables into a dedicated
`memories_1.sqlite` runtime database while keeping thread metadata in
`state_5.sqlite`.
## Changes
- Adds a separate memories DB runtime, migrator, path helpers, telemetry
kind, and Bazel compile data for `state/memory_migrations`.
- Introduces `MemoryStore` behind `StateRuntime::memories()` and moves
memory table/job operations onto that store.
- Drops the old memory tables from the state DB and recreates their
schema in `state/memory_migrations/0001_memories.sql`.
- Updates memory startup, citation usage tracking, rollout pollution
handling, `debug clear-memories`, and app-server `memory/reset` to
operate through the memories DB.
- Preserves cross-DB behavior by hydrating thread metadata from the
state DB when selecting visible memory outputs and checking stage-one
staleness.
## Verification
- Added/updated `codex-state` tests for deleted-thread memory visibility
and already-polluted phase-two enqueue behavior.
- Updated `debug clear-memories`, app-server `memory/reset`, and
memories startup tests to seed and assert memory rows through
`memories_1.sqlite`.
