## Summary
This PR adds `CodexAuth::AgentIdentity` as an explicit auth mode.
An AgentIdentity auth record is a standalone `auth.json` mode. When
`AuthManager::auth().await` loads that mode, it registers one
process-scoped task and stores it in runtime-only state on the auth
value. Header creation stays synchronous after that because the task is
initialized before callers receive the auth object.
This PR also removes the old feature flag path. AgentIdentity is
selected by explicit auth mode, not by a hidden flag or lazy mutation of
ChatGPT auth records.
Reference old stack: https://github.com/openai/codex/pull/17387/changes
## Design Decisions
- AgentIdentity is a real auth enum variant because it can be the only
credential in `auth.json`.
- The process task is ephemeral runtime state. It is not serialized and
is not stored in rollout/session data.
- Account/user metadata needed by existing Codex backend checks lives on
the AgentIdentity record for now.
- `is_chatgpt_auth()` remains token-specific.
- `uses_codex_backend()` is the broader predicate for ChatGPT-token auth
and AgentIdentity auth.

## Summary
This PR fully reverts the previously merged Agent Identity runtime
integration from the old stack:
https://github.com/openai/codex/pull/17387/changes
It removes the Codex-side task lifecycle wiring, rollout/session
persistence, feature flag plumbing, lazy `auth.json` mutation,
background task auth paths, and request callsite changes introduced by
that stack.
This leaves the repo in a clean pre-AgentIdentity integration state so
the follow-up PRs can reintroduce the pieces in smaller reviewable
layers.

## Testing
Tests: targeted Rust checks, cargo-shear, Bazel lock check, and CI.
## Why
The device-key protocol needs an app-server implementation that keeps
local key operations behind the same request-processing boundary as
other v2 APIs.
app-server owns request dispatch, transport policy, documentation, and
JSON-RPC error shaping. `codex-device-key` owns key binding, validation,
platform provider selection, and signing mechanics. Keeping the adapter
thin makes the boundary easier to review and avoids moving local
key-management details into thread orchestration code.
## What changed
- Added `DeviceKeyApi` as the app-server adapter around
`DeviceKeyStore`.
- Converted protocol protection policies, payload variants, algorithms,
and protection classes to and from the device-key crate types.
- Encoded SPKI public keys and DER signatures as base64 protocol fields.
- Routed `device/key/create`, `device/key/public`, and `device/key/sign`
through `MessageProcessor`.
- Rejected remote transports before provider access while allowing local
`stdio` and in-process callers to reach the device-key API.
- Added stdio, in-process, and websocket tests for device-key validation
and transport policy.
- Documented the device-key methods in the app-server v2 method list.
## Test coverage
- `device_key_create_rejects_empty_account_user_id`
- `in_process_allows_device_key_requests_to_reach_device_key_api`
- `device_key_methods_are_rejected_over_websocket`
## Stack
This is PR 3 of 4 in the device-key app-server stack. It is stacked on
#18429.
## Validation
- `cargo test -p codex-app-server device_key`
- `just fix -p codex-app-server`
## Why
Permission approval responses must not be able to grant more access than
the tool requested. Moving this flow to `PermissionProfile` means the
comparison must be profile-shaped instead of `SandboxPolicy`-shaped, and
cwd-relative special paths such as `:cwd` and `:project_roots` must stay
anchored to the turn that produced the request.
## What changed
This implements semantic `PermissionProfile` intersection in
`codex-sandboxing` for file-system and network permissions. The
intersection accepts narrower path grants, rejects broader grants,
preserves deny-read carve-outs and glob scan depth, and materializes
cwd-dependent special-path grants to absolute paths before they can be
recorded for reuse.
The request-permissions response paths now use that intersection
consistently. App-server captures the request turn cwd before waiting
for the client response, includes that cwd in the v2 approval params,
and core stores the requested profile plus cwd for direct TUI/client
responses and Guardian decisions before recording turn- or
session-scoped grants. The TUI app-server bridge now preserves the
app-server request cwd when converting permission approval params into
core events.

## Summary
- attach the authoritative Codex thread id to MCP tool request
`_meta.threadId` for model-initiated tool calls
- attach the same thread id for manual `mcpServer/tool/call` requests
before invoking the MCP server
- cover both metadata helper behavior and the manual app-server MCP path
in tests
needed because the Rust app-server is the last place that still has
authoritative knowledge of “this model-generated MCP tool call belongs
to conversation/thread X” before the request leaves Codex and reaches
Hoopa. It adds threadId to MCP request metadata in the model-generated
tool-call path, using sess.conversation_id, and also does the same for
the manual mcpServer/tool/call path.
## Test plan
- `cargo test -p codex-core

- `cargo test -p codex-app-server

Paired Hoopa consumer PR: https://github.com/openai/openai/pull/833263
Deferred dynamic tools need to round-trip a namespace so a tool returned
by `tool_search` can be called through the same registry key that core
uses for dispatch.
This change adds namespace support for dynamic tool specs/calls,
persists it through app-server thread state, and routes dynamic tool
calls by full `ToolName` while still sending the app the leaf tool name.
Deferred dynamic tools must provide a namespace; non-deferred dynamic
tools may remain top-level.
It also introduces `LoadableToolSpec` as the shared
function-or-namespace Responses shape used by both `tool_search` output
and dynamic tool registration, so dynamic tools use the same wrapping
logic in both paths.

## Summary
Making thread id optional so that we can better cache resources for MCPs
for connectors since their resource templates is universal and not
particular to projects.
- Make `mcpServer/resource/read` accept an optional `threadId`
- Read resources from the current MCP config when no thread is supplied
- Keep the existing thread-scoped path when `threadId` is present
- Update the generated schemas, README, and integration coverage
## Testing
- `just write-app-server-schema`
- `just fmt`
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-mcp`
- `cargo test -p codex-app-server --test all mcp_resource`
- `just fix -p codex-mcp`
- `just fix -p codex-app-server-protocol`
- `just fix -p codex-app-server`
## Why
#18274 made `PermissionProfile` the canonical file-system permissions
shape, but the round-trip from `FileSystemSandboxPolicy` to
`PermissionProfile` still dropped one piece of policy metadata:
`glob_scan_max_depth`.
That field is security-relevant for deny-read globs such as `**/*.env`.
On Linux, bubblewrap sandbox construction uses it to bound unreadable
glob expansion. If a profile copied from active runtime permissions
loses this value and is submitted back as an override, the resulting
`FileSystemSandboxPolicy` can behave differently even though the visible
permission entries look equivalent.
## What changed
- Add `glob_scan_max_depth` to protocol `FileSystemPermissions` and
preserve it when converting to/from `FileSystemSandboxPolicy`.
- Keep legacy `read`/`write` JSON for simple path-only permissions, but
force canonical JSON when glob scan depth is present so the metadata is
not silently dropped.
- Carry `globScanMaxDepth` through app-server
`AdditionalFileSystemPermissions`, generated JSON/TypeScript schemas,
and app-server/TUI conversion call sites.
- Preserve the metadata through sandboxing permission normalization,
merging, and intersection.
- Carry the merged scan depth into the effective
`FileSystemSandboxPolicy` used for command execution, so bounded
deny-read globs reach Linux bubblewrap materialization.
## Verification
- `cargo test -p codex-sandboxing glob_scan -- --nocapture`
- `cargo test -p codex-sandboxing policy_transforms -- --nocapture`
- `just fix -p codex-sandboxing`

## Why
Cloud-hosted sessions need a way for the service that starts or manages
a thread to provide session-owned config without treating all config as
if it came from the same user/project/workspace TOML stack.
The important boundary is ownership: some values should be controlled by
the session/orchestrator, some by the authenticated user, and later some
may come from the executor. The earlier broad config-store shape made
that boundary too fuzzy and overlapped heavily with the existing
filesystem-backed config loader. This PR starts with the smaller piece
we need now: a typed session config loader that can feed the existing
config layer stack while preserving the normal precedence and merge
behavior.
## What Changed
- Added `ThreadConfigLoader` and related typed payloads in
`codex-config`.
- `SessionThreadConfig` currently supports `model_provider`,
`model_providers`, and feature flags.
- `UserThreadConfig` is present as an ownership boundary, but does not
yet add TOML-backed fields.
- `NoopThreadConfigLoader` preserves existing behavior when no external
loader is configured.
- `StaticThreadConfigLoader` supports tests and simple callers.
- Taught thread config sources to produce ordinary `ConfigLayerEntry`
values so the existing `ConfigLayerStack` remains the place where
precedence and merging happen.
- Wired the loader through `ConfigBuilder`, the config loader, and
app-server startup paths so app-server can provide session-owned config
before deriving a thread config.
- Added coverage for:
- translating typed thread config into config layers,
- inserting thread config layers into the stack at the right precedence,
- applying session-provided model provider and feature settings when
app-server derives config from thread params.
## Follow-Ups
This intentionally stops short of adding the remote/service transport.
The next pieces are expected to be:
1. Define the proto/API shape for this interface.
2. Add a client implementation that can source session config from the
service side.
## Verification
- Added unit coverage in `codex-config` for the loader and layer
conversion.
- Added `codex-core` config loader coverage for thread config layer
precedence.
- Added app-server coverage that verifies session thread config wins
over request-provided config for model provider and feature settings.
## Summary
Adds a second realtime v2 function tool, `remain_silent`, so the
realtime model has an explicit non-speaking action when the
collaboration mode or latest context says it should not answer aloud.
This is stacked on #18597.
## Design
- Advertise `remain_silent` alongside `background_agent` in realtime v2
conversational sessions.
- Parse `remain_silent` function calls into a typed
`RealtimeEvent::NoopRequested` event.
- Have core answer that function call with an empty
`function_call_output` and deliberately avoid `response.create`, so no
follow-up realtime response is requested.
- Keep the event hidden from app-server/TUI surfaces; it is operational
plumbing, not user-visible conversation content.
Migrate the conversation summary App Server methods to ThreadStore
Because this app server api allows explicitly fetching the thread by
rollout path, intercept that case in the app server code and (a) route
directly to underlying local thread store methods if we're using a local
thread store, or (b) throw an unsupported error if we're using a remote
thread store. This keeps the thread store API clean and all filesystem
operations inside of the local thread store, which pushing the
"fundamental incompatibility" check as early as possible.
## Summary
This PR aims to improve integration between the realtime model and the
codex agent by sharing more context with each other. In particular, we
now share full realtime conversation transcript deltas in addition to
the delegation message.
realtime_conversation.rs now turns a handoff into:
```
<realtime_delegation>
<input>...</input>
<transcript_delta>...</transcript_delta>
</realtime_delegation>
```
## Implementation notes
The transcript is accumulated in the realtime websocket layer as parsed
realtime events arrive. When a background-agent handoff is requested,
the current transcript snapshot is copied onto the handoff event and
then serialized by `realtime_conversation.rs` into the hidden realtime
delegation envelope that Codex receives as user-turn context.
For Realtime V2, the session now explicitly enables input audio
transcription, and the parser handles the relevant input/output
transcript completion events so the snapshot includes both user speech
and realtime model responses. The delegation `<input>` remains the
actual handoff request, while `<transcript_delta>` carries the
surrounding conversation history for context.
Reviewers should note that the transcript payload is intended for Codex
context sharing, not UI rendering. The realtime delegation envelope
should stay hidden from the user-facing transcript surface, while still
being included in the background-agent turn so Codex can answer with the
same conversational context the realtime model had.
Wires patch_updated events through app_server. These events are parsed
and streamed while apply_patch is being written by the model. Also adds 500ms of buffering to the patch_updated events in the diff_consumer.
The eventual goal is to use this to display better progress indicators in
the codex app.
- Replace the active models-manager catalog with the deleted core
catalog contents.
- Replace stale hardcoded test model slugs with current bundled model
slugs.
- Keep this as a stacked change on top of the cleanup PR.
## Why
`PermissionProfile` needs stable, canonical file-system semantics before
it can become the primary runtime permissions abstraction. Without a
canonical form, callers have to keep re-deriving legacy sandbox maps and
profile comparisons remain lossy or order-dependent.
## What changed
This adds canonicalization helpers for `FileSystemPermissions` and
`PermissionProfile`, expands special paths into explicit sandbox
entries, and updates permission request/conversion paths to consume
those canonical entries. It also tightens the legacy bridge so root-wide
write profiles with narrower carveouts are not silently projected as
full-disk legacy access.
## Verification
- `cargo test -p codex-protocol
root_write_with_read_only_child_is_not_full_disk_write -- --nocapture`
- `cargo test -p codex-sandboxing permission -- --nocapture`
- `cargo test -p codex-tui permissions -- --nocapture`
## Why
This addresses the review comment from #17751 about `marketplace/remove`
app-server test portability:
https://github.com/openai/codex/pull/17751#discussion_r3104378613
The API returns the removed installed root using the app-server's
effective `CODEX_HOME`. On macOS, temporary directory paths can appear
as either `/var/...` or `/private/var/...`, so comparing one raw path
against another can fail even when `marketplace/remove` behaves
correctly.
## What changed
- Removed the direct whole-response equality assertion for the installed
root path.
- Asserted the stable response field, `marketplace_name`, directly.
- Compared the expected and returned installed-root paths after
canonicalizing their existing parent directories, which avoids requiring
the removed leaf directory to still exist.
## Verification
- `cargo test -p codex-app-server
marketplace_remove_deletes_config_and_installed_root`
- `cargo test -p codex-app-server marketplace_remove`
## Summary
Add a new app-server `marketplace/remove` RPC on top of the shared
marketplace-remove implementation.
This change:
- adds `MarketplaceRemoveParams` / `MarketplaceRemoveResponse` to the
app-server protocol
- wires the new request through `codex_message_processor`
- reuses the shared core marketplace-remove flow from the stacked
refactor PR
- updates generated schema files and adds focused app-server coverage
## Validation
- `just write-app-server-schema`
- `just fmt`
- heavy compile/test coverage deferred to GitHub CI per request
## Summary
- persist registered agent tasks in the session state update stream so
the thread can reuse them
- prewarm task registration once identity registration succeeds, while
keeping startup failures best-effort
- isolate the session-side task lifecycle into a dedicated module so
AgentIdentityManager and RegisteredAgentTask do not leak across as many
core layers
## Testing
- cargo test -p codex-core startup_agent_task_prewarm
- cargo test -p codex-core
cached_agent_task_for_current_identity_clears_stale_task
- cargo test -p codex-core record_initial_history_
Adds max_context_window to model metadata and routes core context-window
reads through resolved model info. Config model_context_window overrides
are clamped to max_context_window when present; without an override, the
model context_window is used.
## Summary
- Populate `PluginDetail.description` in core for uninstalled cross-repo
plugins when detailed fields are unavailable until install.
- Include the source Git URL plus optional path/ref/sha details in that
fallback description.
- Keep `details_unavailable_reason` as the structured signal while
app-server forwards the description normally.
- Add plugin-read coverage proving the response does not clone the
remote source just to show the message.
## Why
Uninstalled cross-repo plugins intentionally return sparse detail data
so listing/reading does not clone the plugin source. Without a
description, Desktop and TUI detail pages look like an ordinary empty
plugin. This gives users a concrete explanation and source pointer while
keeping the existing structured reason available for callers.
## Validation
- `just fmt`
- `cargo test -p codex-core
read_plugin_for_config_uninstalled_git_source_requires_install_without_cloning`
- `cargo test -p codex-app-server plugin_read --test all`
- `just fix -p codex-core`
- `just fix -p codex-app-server`
Note: `cargo test -p codex-app-server` was also attempted before the
latest refactor and failed broadly in unrelated v2
thread/realtime/review/skills suites; the new plugin-read test passed in
that run as well.
Cap the model-visible skills section to a small share of the context
window, with a fallback character budget, and keep only as many implicit
skills as fit within that budget.
Emit a non-fatal warning when enabled skills are omitted, and add a new
app-server warning notification
Record thread-start skill metrics for total enabled skills, kept skills,
and whether truncation happened

## Summary
- trust-gate project `.codex` layers consistently, including repos that
have `.codex/hooks.json` or `.codex/execpolicy/*.rules` but no
`.codex/config.toml`
- keep disabled project layers in the config stack so nested trusted
project layers still resolve correctly, while preventing hooks and exec
policies from loading until the project is trusted
- update app-server/TUI onboarding copy to make the trust boundary
explicit and add regressions for loader, hooks, exec-policy, and
onboarding coverage
## Security
Before this change, an untrusted repo could auto-load project hooks or
exec policies from `.codex/` as long as `config.toml` was absent. This
makes trust the single gate for project-local config, hooks, and exec
policies.

## Summary
Update the plugin API for the new remote plugin model.
The mental model is no longer “keep local plugin state in sync with
remote.” Instead, local and remote plugins are becoming separate
sources. Remote catalog entries can be shown directly from the remote
API before installation; after installation they are still downloaded
into the local cache for execution, but remote installed state will come
from the API and be held in memory rather than being read from config.
• ## API changes
- Remove `forceRemoteSync` from `plugin/list`, `plugin/install`, and
`plugin/uninstall`.
- Remove `remoteSyncError` from `plugin/list`.
- Add remote-capable metadata to `plugin/list` / `plugin/read`:
- nullable `marketplaces[].path`
- `source: { type: "remote", downloadUrl }`
- URL asset fields alongside local path fields:
`composerIconUrl`, `logoUrl`, `screenshotUrls`
- Make `plugin/read` and `plugin/install` source-compatible:
- `marketplacePath?: AbsolutePathBuf | null`
- `remoteMarketplaceName?: string | null`
- exactly one source is required at runtime
## Summary
First PR in the split from #17956.
- adds the core/app-server `RateLimitReachedType` shape
- maps backend `rate_limit_reached_type` into Codex rate-limit snapshots
- carries the field through app-server notifications/responses and
generated schemas
- updates existing constructors/tests for the new optional field
## Validation
- `cargo test -p codex-backend-client`

To improve performance of UI loads from the app, add two main
improvements:
1. The `thread/list` api now gets a `sortDirection` request field and a
`backwardsCursor` to the response, which lets you paginate forwards and
backwards from a window. This lets you fetch the first few items to
display immediately while you paginate to fill in history, then can
paginate "backwards" on future loads to catch up with any changes since
the last UI load without a full reload of the entire data set.
2. Added a new `thread/turns/list` api which also has sortDirection and
backwardsCursor for the same behavior as `thread/list`, allowing you the
same small-fetch for immediate display followed by background fill-in
and resync catchup.
Summary
- replace the thread/read persisted-load helper with
ThreadStore::read_thread
- move SQLite/rollout summary, name, fork metadata, and history loading
for persisted reads into LocalThreadStore
- leave getConversationSummary unchanged for a later PR
Context
- Replaces closed stacked PR #18232 after PR #18231 merged and its base
branch was deleted.
… import
## Why
`externalAgentConfig/import` used to spawn plugin imports in the
background and return immediately. That meant local marketplace imports
could still be in flight when the caller refreshed plugin state, so
newly imported plugins would not show up right away.
This change makes local marketplace imports complete before the RPC
returns, while keeping remote marketplace imports asynchronous so we do
not block on remote fetches.
## What changed
- split plugin migration details into local and remote marketplace
imports based on the external config source
- import local marketplaces synchronously during
`externalAgentConfig/import`
- return pending remote plugin imports to the app-server so it can
finish them in the background
- clear the plugin and skills caches before responding to plugin
imports, and again after background remote imports complete, so the next
`plugin/list` reloads fresh state
- keep marketplace source parsing encapsulated behind
`is_local_marketplace_source(...)` instead of re-exporting the internal
enum
- add core and app-server coverage for the synchronous local import path
and the pending remote import path
## Verification
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-core` (currently fails an existing unrelated
test:
`config_loader::tests::cli_override_can_update_project_local_mcp_server_when_project_is_trusted`)
- `cargo test` (currently fails existing `codex-app-server` integration
tests in MCP/skills/thread-start areas, plus the unrelated `codex-core`
failure above)
Load plugin manifests through a shared discoverable-path helper so
manifest reads, installs, and skill names all see the same alternate
manifest location.
## Summary
- Switch the unknown-thread MCP resource read test from the stdio
subprocess to the in-process app-server path.
- Keep the assertion focused on the returned error message while
avoiding child-process teardown timing issues in nextest.
## Testing
- Not run (not requested)
## Summary
- set the realtime v2 server VAD silence delay to 500ms
- update the default realtime 1.5 backend prompt to the v4 text
- keep the session payload and prompt rendering tests aligned with those
changes
## Why
- the VAD change gives the voice path a longer pause before ending the
user's turn
- the prompt change makes the default bundled realtime prompt match the
current v4 content

## Notes
The full local app-server E2E path is still being debugged after PR
creation. The current branch stack is directionally ready for review
while that follow-up continues.
## Problem
When a user resumed or forked a session, the TUI could render the
restored thread history immediately, but it did not receive token usage
until a later model turn emitted a fresh usage event. That left the
context/status UI blank or stale during the exact window where the user
expects resumed state to look complete. Core already reconstructed token
usage from the rollout; the missing behavior was app-server lifecycle
replay to the client that just attached.
## Mental model
Token usage has two representations. The rollout is the durable source
of historical `TokenCount` events, and the core session cache is the
in-memory snapshot reconstructed from that rollout on resume or fork.
App-server v2 clients do not read core state directly; they learn about
usage through `thread/tokenUsage/updated`. The fix keeps those roles
separate: core exposes the restored `TokenUsageInfo`, and app-server
sends one targeted notification after a successful `thread/resume` or
`thread/fork` response when that restored snapshot exists.
This notification is not a new model event. It is a replay of
already-persisted state for the client that just attached. That
distinction matters because using the normal core event path here would
risk duplicating `TokenCount` entries in the rollout and making future
resumes count historical usage twice.
## Non-goals
This change does not add a new protocol method or payload shape. It
reuses the existing v2 `thread/tokenUsage/updated` notification and the
TUI’s existing handler for that notification.
This change does not alter how token usage is computed, accumulated,
compacted, or written during turns. It only exposes the token usage that
resume and fork reconstruction already restored.
This change does not broadcast historical usage replay to every
subscribed client. The replay is intentionally scoped to the connection
that requested resume or fork so already-attached clients are not
surprised by an old usage update while they may be rendering live
activity.
## Tradeoffs
Sending the usage notification after the JSON-RPC response preserves a
clear lifecycle order: the client first receives the thread object, then
receives restored usage for that thread. The tradeoff is that usage is
still a notification rather than part of the `thread/resume` or
`thread/fork` response. That keeps the protocol shape stable and avoids
duplicating usage fields across response types, but clients must
continue listening for notifications after receiving the response.
The helper selects the latest non-in-progress turn id for the replayed
usage notification. This is conservative because restored usage belongs
to completed persisted accounting, not to newly attached in-flight work.
The fallback to the last turn preserves a stable wire payload for
unusual histories, but histories with no meaningful completed turn still
have a weak attribution story.
## Architecture
Core already seeds `Session` token state from the last persisted rollout
`TokenCount` during `InitialHistory::Resumed` and
`InitialHistory::Forked`. The new core accessor exposes the complete
`TokenUsageInfo` through `CodexThread` without giving app-server direct
session mutation authority.
App-server calls that accessor from three lifecycle paths: cold
`thread/resume`, running-thread resume/rejoin, and `thread/fork`. In
each path, the server sends the normal response first, then calls a
shared helper that converts core usage into
`ThreadTokenUsageUpdatedNotification` and sends it only to the
requesting connection.
The tests build fake rollouts with a user turn plus a persisted token
usage event. They then exercise `thread/resume` and `thread/fork`
without starting another model turn, proving that restored usage arrives
before any next-turn token event could be produced.
## Observability
The primary debug path is the app-server JSON-RPC stream. After
`thread/resume` or `thread/fork`, a client should see the response
followed by `thread/tokenUsage/updated` when the source rollout includes
token usage. If the notification is absent, check whether the rollout
contains an `event_msg` payload of type `token_count`, whether core
reconstruction seeded `Session::token_usage_info`, and whether the
connection stayed attached long enough to receive the targeted
notification.
The notification is sent through the existing
`OutgoingMessageSender::send_server_notification_to_connections` path,
so existing app-server tracing around server notifications still
applies. Because this is a replay, not a model turn event, debugging
should start at the resume/fork handlers rather than the turn event
translation in `bespoke_event_handling`.
## Tests
The focused regression coverage is `cargo test -p codex-app-server
emits_restored_token_usage`, which covers both resume and fork. The core
reconstruction guard is `cargo test -p codex-core
record_initial_history_seeds_token_info_from_rollout`.
Formatting and lint/fix passes were run with `just fmt`, `just fix -p
codex-core`, and `just fix -p codex-app-server`. Full crate test runs
surfaced pre-existing unrelated failures in command execution and plugin
marketplace tests; the new token usage tests passed in focused runs and
within the app-server suite before the unrelated command execution
failure.
## Summary
- replace the unsubscribe-during-turn test's sleep/polling flow with a
gated streaming SSE response
- add request-count notification support to the streaming SSE test
server so the test can wait for the in-flight Responses request
deterministically
## Scope
- codex-rs/app-server/tests/suite/v2/thread_unsubscribe.rs
- codex-rs/core/tests/common/streaming_sse.rs
## Validation
- Not run locally; this is a narrow extraction from the prior CI-green
branch.

Make sure Bazel logs shows every errors so that we can debug flakes +
fix a small flake on Windows by updating the sleep command to a
`Start-Sleep` instead of a PowerShell nested command (otherwise we had
double nesting which is absurdely slow)
## Summary
- Make command/exec output-delta tests accumulate streamed chunks
instead of assuming complete logical output in a single notification.
- Collect stdout and stderr independently so stream interleaving does
not fail the pipe streaming test.
## Why
The command/exec protocol exposes output as deltas, so tests should not
rely on chunk boundaries being stable. A line like `out-start\n` may
arrive split across multiple notifications, and stdout/stderr
notifications may interleave.
## Validation
- `just fmt`
- `git diff --check`
- `cargo test -p codex-app-server suite::v2::command_exec`
## Summary
- wrap realtime startup context in
`<startup_context>...</startup_context>` tags
- prefix V2 mirrored user text and relayed backend text with `[USER]` /
`[BACKEND]`
- remove the V2 progress suffix and replace the final V2 handoff output
with a short completion acknowledgement while preserving the existing V1
wrapper
## Testing
- cargo test -p codex-api

-- --exact
- cargo test -p codex-app-server webrtc_v2_background_agent_

Dismiss stale TUI app-server approvals after remote resolution
When an approval, user-input prompt, or elicitation request is resolved
by another client, the TUI now dismisses the matching local UI instead
of leaving stale prompts behind and emitting a misleading local
cancellation.
This change teaches pending app-server request tracking to map
`serverRequest/resolved` notifications back to the concrete request type
and stable request key, then propagates that resolved request into TUI
prompt state. Approval, request-user-input, and MCP elicitation overlays
now drop the resolved current or queued request quietly, advance to the
next queued request when present, and avoid emitting abort/cancel events
for stale UI.
The latest update also retires matching prompts while they are still
deferred behind active streaming and suppresses buffered active-thread
requests whose app-server request id has already been resolved before
drain. `ChatWidget` removes a resolved request from both the deferred
interrupt queue and the materialized bottom-pane stack, while
active-thread request handling verifies the app-server request is still
pending before showing a prompt. Lifecycle events such as exec begin/end
remain queued so approved work can still render normally.
Tests cover resolved-request mapping, overlay dismissal behavior,
deferred prompt pruning for same-turn user input, exec approval IDs,
lifecycle-event retention, and the buffered active-thread ordering
regression.
Validation:
- `just fmt`
- `git diff --check`
- `cargo test -p codex-tui
resolved_buffered_approval_does_not_become_actionable_after_drain`
- `cargo test -p codex-tui

- `cargo test -p codex-tui chatwidget::interrupts`
- `just fix -p codex-tui`

Builds on top of #17659
Move the filesystem + sqlite thread listing-related operations inside of
a local ThreadStore implementation and call ThreadStore from the places
that used to perform these filesystem/sqlite operations.
This is the first of a series of PRs that will implement the rest of the
local ThreadStore.
Testing:
- added unit tests for the thread store implementation
- adjusted some unit tests in the realtime + personality packages whose
callsites changed. Specifically I'm trying to hide ThreadMetadata inside
of the local implementation and make ThreadMetadata a sqlite
implementation detail concern rather than a public interface, preferring
the more generate StoredThread interface instead
- added a corner case test for the personality migration package that
wasn't covered by the existing test suite
- adjust the behavior of searched thread listing to run the existing
local rollout repair/backfill pass _before_ querying SQLite results, so
callers using ThreadStore::list_threads do not miss matches after a
partial metadata warm-up
## Summary
Stack PR 2 of 4 for feature-gated agent identity support.
This PR adds agent identity registration behind
`features.use_agent_identity`. It keeps the app-server protocol
unchanged and starts registration after ChatGPT auth exists rather than
requiring a client restart.
## Stack
- PR1: https://github.com/openai/codex/pull/17385 - add
`features.use_agent_identity`
- PR2: https://github.com/openai/codex/pull/17386 - this PR
- PR3: https://github.com/openai/codex/pull/17387 - register agent tasks
when enabled
- PR4: https://github.com/openai/codex/pull/17388 - use `AgentAssertion`
downstream when enabled
## Validation
Covered as part of the local stack validation pass:
- `just fmt`
- `cargo test -p codex-core --lib agent_identity`
- `cargo test -p codex-core --lib agent_assertion`
- `cargo test -p codex-core --lib websocket_agent_task`
- `cargo test -p codex-api api_bridge`
- `cargo build -p codex-cli --bin codex`
## Notes
The full local app-server E2E path is still being debugged after PR
creation. The current branch stack is directionally ready for review
while that follow-up continues.
stacked on #17402.
MCP tools returned by `tool_search` (deferred tools) get registered in
our `ToolRegistry` with a different format than directly available
tools. this leads to two different ways of accessing MCP tools from our
tool catalog, only one of which works for each. fix this by registering
all MCP tools with the namespace format, since this info is already
available.
also, direct MCP tools are registered to responsesapi without a
namespace, while deferred MCP tools have a namespace. this means we can
receive MCP `FunctionCall`s in both formats from namespaces. fix this by
always registering MCP tools with namespace, regardless of deferral
status.
make code mode track `ToolName` provenance of tools so it can map the
literal JS function name string to the correct `ToolName` for
invocation, rather than supporting both in core.
this lets us unify to a single canonical `ToolName` representation for
each MCP tool and force everywhere to use that one, without supporting
fallbacks.
