Shijie RaoandGitHub fc8c6b7384 Add per-turn multi-agent mode (#28685)
## Why

Multi-agent v2 currently carries an explicit-request-only delegation
rule in its static usage hint. That provides a safe default, but it
prevents clients from selecting proactive delegation per turn without
changing static guidance or rewriting prior model context.

This change makes delegation mode a session selection that can be
updated through `turn/start`, while deriving the effective model-visible
mode separately for each turn. Eligible multi-agent v2 turns remain
explicit-request-only unless proactive mode is both selected and
enabled.

## What changed

- Add the experimental `turn/start.multiAgentMode` parameter with
`explicitRequestOnly` and `proactive` values. Omission retains the
loaded session's current optional selection.
- Add the default-off `features.multi_agent_mode` feature gate. Eligible
multi-agent v2 turns use the selected mode when enabled; an unset
selection or disabled gate resolves to `explicitRequestOnly`.
- Treat mode prompting as inapplicable for multi-agent v1 and other
unsupported session configurations, producing no multi-agent mode
developer message rather than rejecting the turn.
- Move the explicit-request-only rule out of the static v2 usage hint
and into a bounded, tagged developer context fragment.
- Emit the effective mode in initial context and only when that
effective mode changes on later turns.
- Persist the effective mode in `TurnContextItem` as the durable
baseline for resume and context-update comparisons.

Historical rollout items are not rewritten. Later mode developer
messages establish the current rule incrementally.

## Not covered

- Initial selection through `thread/start` and selected-mode reporting
from thread lifecycle/settings APIs; those are isolated in the stacked
#28792.
- A TUI control or slash command for selecting the mode.
- Persisting a preferred mode to `config.toml`; selection remains
session/turn scoped.
- Changes to multi-agent concurrency limits, tool availability, or model
catalog capability declarations.
- Rewriting historical rollout prompt items. Cold resume restores the
latest persisted effective mode when available while leaving historical
developer messages intact.

## Verification

- `CARGO_INCREMENTAL=0 just test -p codex-core multi_agent_mode`
- Focused app-server coverage verifies that `turn/start.multiAgentMode`
produces proactive developer instructions for an eligible v2 turn.

## Stack

Followed by #28792, which adds `thread/start` initialization and
lifecycle/settings observability.

Adam Perry @ OpenAIandGitHub dce673905a core: load AGENTS.md from foreign environments (#28958)
## Why

Make it possible to load AGENTS.md from remote exec-servers whose OS is
different than app-server.

## What

- keep `AGENTS.md` discovery and provenance as `PathUri`, with
root-aware parent and ancestor traversal
- expose lifecycle instruction sources as legacy app-server path strings
in events while retaining `PathUri` internally
- preserve and test mixed POSIX and Windows paths in model context and
TUI status output
- cover remote Windows loading end to end by seeding the Wine prefix
through host filesystem APIs
- fix bug in `PathUri`'s parent() implementation that would erase
Windows drive letters

charlesgong-openaiandGitHub 3959ab0ffc [codex] Track plugin install and import telemetry failures (#28731)
## Summary
- Track plugin install failures through the unified
`codex_plugin_install_failed` event for local installs, remote install
preflight failures, bundle failures, and remote catalog/backend
failures.
- Send classified `error_type` values in plugin install failure
analytics instead of raw error strings.
- Stop sending raw external-agent import errors in analytics while
preserving raw failure details in app-facing import
notifications/history.
- Keep raw plugin/migration diagnostics in `tracing::warn!` logs.
- Keep remote failure plugin names as the existing local placeholder
(`unknown`) and remove the extra telemetry plugin-name override.
- Change `ExternalAgentConfigImportParams.source` from a generated enum
to `string | null`, with legacy `claudeCode` / `claudeCowork` inputs
normalized to existing analytics values.

Jeremy RoseandGitHub 7dc7096ae1 [codex] Restore thread recency with compatible migration history (#28671)
## Summary

- Revert #28655, restoring the thread `recencyAt` behavior introduced by
#27910.
- Move `threads_recency_at` to migration 0039 so it no longer collides
with `external_agent_config_imports` at version 0038.
- Repair databases that already applied the recency migration as version
38 by moving the matching migration-history row to version 39 before
SQLx validation. The current version-38 migration can then apply
normally.

## Validation

- `just test -p codex-state
migrations::tests::repairs_recency_migration_that_was_applied_as_version_38`
- `just test -p codex-state -p codex-rollout -p codex-thread-store -p
codex-app-server-protocol -p codex-tui`: 3,439 passed; six TUI tests
could not open the machine's existing read-only incident database at
`~/.codex/sqlite/state_5.sqlite`.
- `just fix -p codex-state`
- `just fmt`
- Verified that state migration versions are unique.

pakrym-oaiandGitHub cb15c64760 Revert thread recencyAt for sidebar ordering (#28655)
## Why

Revert #27910 to remove the newly introduced thread `recencyAt`
persistence and API behavior from `main`.

## What changed

This reverts commit `fac3158c2a783095768076489815f361fa9b0db4`,
including the state migration, thread-store propagation, app-server API
surface, generated schemas, and related tests.

## Validation

Jeremy RoseandGitHub fac3158c2a Add thread recencyAt for sidebar ordering (#27910)
## Summary

Add a server-owned `recencyAt` timestamp and `recency_at` thread-list
sort key for product recency ordering while preserving the existing
meaning of `updatedAt` as the latest persisted thread mutation.

This is the server-side alternative to #27697. Rather than narrowing
`updatedAt`, clients can sort the sidebar by `recency_at` and continue
treating `updatedAt` as mutation time.

Paired Codex Apps PR:
[openai/openai#1024599](https://github.com/openai/openai/pull/1024599)

## Contract

- `recencyAt` initializes when a thread is created.
- A turn start advances `recencyAt` monotonically.
- Commentary, agent output, tool results, token/accounting updates, turn
completion, archive, unarchive, resume, and generic metadata writes do
not advance it.
- `updatedAt` retains its existing behavior and continues to advance for
persisted thread mutations.
- Current servers populate `recencyAt`; the response field is optional
in generated TypeScript so clients connected to older servers can fall
back to `updatedAt`.
- Filesystem-only fallback uses existing updated/mtime ordering when
SQLite is unavailable.

## Persistence and compatibility

Migration 0038 adds second- and millisecond-precision recency columns,
backfills them from the existing updated timestamp, creates list
indexes, and includes an insert trigger so older binaries writing to a
migrated database seed recency without causing later mutations to
advance it.

Generic metadata upserts preserve existing recency values. Turn-start
updates use a dedicated monotonic touch, and process-local allocation
keeps millisecond cursor values unique. State DB list, search, read,
filtered-list repair, rollout fallback propagation, and app-server
conversions all carry the new field.

## API

`Thread` responses include:

```ts
recencyAt?: number
```

`thread/list` and `thread/search` accept:

```json
{ "sortKey": "recency_at" }
```

Generated TypeScript and JSON schemas are included.

Celia ChenandGitHub 12aaeb7bf8 [codex] expose Bedrock credential source in account/read (#27751)
## Why

`account/read` currently reports only `type: "amazonBedrock"`, so
clients cannot distinguish a Codex-managed Bedrock API key from
credentials supplied by AWS. The app UI needs that distinction to render
the appropriate account state without duplicating provider-auth logic.

Credential-source selection belongs to the Bedrock model provider
because it already owns the precedence between managed Bedrock auth and
the external AWS credential path. This builds on #27443 and #27689.

## What changed

- Added `AmazonBedrockCredentialSource` with `codexManaged` and
`awsManaged` values.
- Included the selected credential source in
`ProviderAccount::AmazonBedrock` and the app-server `Account` response.
- Made `AmazonBedrockModelProvider::account_state()` classify the source
from its managed-auth state.
- Regenerated the app-server JSON and TypeScript schemas.
- Updated app-server account documentation and downstream TUI matches.

`codexManaged` means the provider found a managed Bedrock API key.
`awsManaged` identifies the provider's external AWS credential path; it
does not assert that the AWS credential chain has been validated.

## Testing

- Added model-provider coverage for Codex-managed precedence and
AWS-managed fallback.
- Added app-server protocol serialization coverage for both wire values.
- Added app-server integration coverage for both `account/read`
responses.
- `just test -p codex-protocol -p codex-model-provider -p
codex-app-server-protocol` (497 tests passed).

After rebasing onto #27711, the `codex-app-server` test target compiled
past the image-generation `PathUri` migration. Local linking was then
interrupted by disk exhaustion (`No space left on device`).

jayandGitHub bef99f861b feat(app-server): expose rate-limit reset credits (#28143)
## Why

Codex users can earn personal rate-limit reset credits, but app-server
clients do not currently have an API for reading or redeeming them. This
adds the backend and protocol foundation used by the `/usage` TUI flow
in #28154.

## What changed

- Extend `account/rateLimits/read` with a nullable
`rateLimitResetCredits` summary sourced from the existing usage
response.
- Add backend-client and app-server support for consuming a reset with a
caller-generated idempotency key. A UUID is recommended, and clients
reuse the same key when retrying the same logical reset.
- Return only the consume `outcome`; clients refetch
`account/rateLimits/read` for updated window state.
- Document the response field and each consume outcome, and regenerate
the JSON and TypeScript schema fixtures.
- Clarify in `AGENTS.md` that new app-server string enum values use
camelCase on the wire.
- Update the existing TUI response fixture for the expanded protocol
shape.
- Add coverage for authentication, response mapping, backend failures,
consume outcomes, and request timeout behavior.

## Validation

- `just test -p codex-app-server-protocol` — 231 passed.
- `just test -p codex-backend-client` — 14 passed.
- Focused `codex-app-server` reset-credit tests — 5 passed.
- Focused `codex-tui` protocol response fixture test — passed.
- `just fix -p codex-backend-client -p codex-app-server-protocol -p
codex-app-server` — passed.

Eric TrautandGitHub 576f603440 Remove TUI realtime voice support (#27801)
## Why

Removes the realtime audio support from TUI.

## What Changed

- Removed the TUI `/realtime` and realtime `/settings` command paths.
- Deleted TUI voice capture/playback, WebRTC session handling,
audio-device selection UI, and recording-meter code.
- Removed TUI realtime tests and snapshots that covered the deleted
surfaces.
- Dropped the TUI-only `cpal` and `codex-realtime-webrtc` dependencies
and refreshed the Rust/Bazel locks.

stefanstokic-oaiandGitHub 743a4147d9 [codex] restore source-specific import copy (#27703)
## Summary

- restore source-specific wording across the `/import` picker, lifecycle
messages, diagnostics, and help text
- update the matching Unix and Windows snapshots
- leave import behavior unchanged

## Why

The import path currently supports one source, so the UI should identify
that source directly instead of presenting the flow as
provider-agnostic.

## Validation

- `just test -p codex-tui external_agent_config_migration` (12 passed)
- `just fix -p codex-tui`
- `just fmt`

Eric TrautandGitHub 78bab04116 [1 of 3] Support long raw TUI goal objectives (#27508)
## Stack

1. **[1 of 3] Support long raw TUI goal objectives** - this PR
2. [2 of 3] Support long pasted text in TUI goals - #27509
3. [3 of 3] Support images in TUI goals - #27510

## Why

`thread/goal/set` limits persisted objective text to 4000 characters.
The TUI used to reject raw `/goal` objectives above that limit, even
though the client can make them usable by writing the long text to a
file and storing a short objective that points at that file.

This also needs to work for remote app-server sessions: filesystem API
calls must create files on the app-server host, and the stored path must
be meaningful to the agent on that host.

## What Changed

- Adds an app-server-host path helper so TUI code can build paths that
are resolved on the app-server host rather than the TUI host.
- Adds TUI app-server session helpers for `fs/createDirectory`,
`fs/writeFile`, `fs/readFile`, and `fs/remove` that work for embedded
and remote app-server sessions without changing the app-server protocol.
- Materializes oversized raw `/goal` objectives into
`$CODEX_HOME/attachments/<uuid>/goal-objective.md` through the
app-server filesystem APIs, then stores a short, readable objective that
directs the agent to that file.
- Reads managed objective files back for `/goal edit`. Other goal UI
renders the readable stored objective normally, without
managed-file-specific presentation logic.
- Recognizes managed references only when they name the expected
generated file under the app server's reported `$CODEX_HOME`, and cleans
up newly materialized files when goal replacement or setting does not
complete.

## Verification

- Added/updated TUI tests for raw oversized `/goal` submission, large
inline-paste expansion, queued oversized goals, app-facing
materialization before `thread/goal/set`, managed-path validation,
editing, and cleanup.
- Added/updated app-server-client remote coverage for initialized remote
Codex home handling.

## Manual Testing

- Ran the real TUI against a Unix-socket app server with different local
and server `$CODEX_HOME` directories. Oversized goals wrote only under
the server home, and persisted references used the server-canonical path
rather than the TUI path.
- Exercised 3,999-, 4,000-, and 4,001-character raw objectives. The
first two stayed inline without new files; the 4,001-character objective
became a managed objective file.
- Submitted a larger 8,275-character objective, verified its full
contents on the app-server host, and observed the goal continuation open
the referenced server-side file.
- Opened `/goal edit` for a managed objective and verified the full text
was restored through remote `fs/readFile`.
- Submitted an oversized replacement while a goal was active, verified
no file was written before confirmation, then canceled and confirmed
that the existing goal and attachment count were unchanged.

Celia ChenandGitHub 06afd63f4a feat: add Bedrock API key as a managed auth mode (#27443)
## Why

Codex needs to manage Amazon Bedrock API key credentials through the
existing auth lifecycle instead of introducing a separate auth manager
or provider-specific credential file. Treating Bedrock API key login as
a primary auth mode gives it the same persistence, keyring, reload, and
logout behavior as the existing OpenAI API key and ChatGPT modes.

The credential is valid only for the `amazon-bedrock` model provider.
OpenAI-compatible providers must reject this auth mode rather than
treating the Bedrock key as an OpenAI bearer token.

## What changed

- Added `bedrockApiKey` as an app-server `AuthMode` and
`CodexAuth::BedrockApiKey` as a primary `AuthManager` mode.
- Added `BedrockApiKeyAuth`, containing the API key and AWS region, to
the existing `AuthDotJson` payload stored in `$CODEX_HOME/auth.json` or
the configured keyring backend.
- Added `login_with_bedrock_api_key(...)`, parallel to
`login_with_api_key(...)`, which replaces the current stored login with
Bedrock credentials.
- Reused generic auth reload and logout behavior instead of adding a
Bedrock-specific auth manager or logout path.
- Updated login restrictions, status reporting, diagnostics, telemetry
classification, generated app-server schemas, and auth fixtures for the
new mode.
- Added explicit errors when Bedrock API key auth is selected with an
OpenAI-compatible model provider.

This PR establishes managed storage and auth-mode behavior. Routing the
managed key and region into Amazon Bedrock requests will be in follow-up
PRs.

Eric TrautandGitHub 9d87b771ce Add session delete commands in CLI and TUI (#27476)
## Summary

The app server exposes `thread/delete`, but users cannot invoke it from
the CLI or TUI. Because deletion is irreversible, the user-facing
commands need deliberate confirmation and safer handling of name-based
targets.

- Add `codex delete <SESSION>` with interactive confirmation,
restricting `--force` to UUID targets.
- Resolve exact names across active and archived sessions, including
renamed sessions, and validate prompted UUID targets before
confirmation.
- Add a `/delete` command with a confirmation popup that warns the
current session and its subagent threads will be permanently deleted.

## Manual testing

- Deleted by UUID with `--force` and verified the rollout, session-index
entry, and database row were removed.
- Exercised name-based confirmation for both cancellation and
affirmative deletion; cancellation preserved the session and
confirmation removed it.
- Verified deletion refuses to proceed without `--force`, while
`--force` rejects names, including duplicate names.
- Verified duplicate-name confirmation displays the concrete UUID
selected.
- Deleted an archived session by name.
- Verified an already-missing UUID fails before displaying a
confirmation prompt.
- Exercised `/delete` in the TUI: the popup defaults to No, cancellation
preserves the session, and confirmation deletes the session and exits.
- Verified that `codex delete` works for both archived and non-archived
sessions.

stefanstokic-oaiandGitHub b4445f2758 [codex] add /import for external agents (#27071)
## Why

External-agent import should be discoverable and deliberate without
blocking startup or claiming the public `codex [PROMPT]` CLI namespace.
The slash command keeps the flow local to the interactive TUI and reuses
the existing app-server import API.

## What changed

- add the user-facing `/import` slash command
- detect external-agent importable items only when the command is
invoked
- run imports through the embedded local app-server
- show start and completion messages, refresh configuration, and block
duplicate imports while one is pending
- reject the flow for unsupported remote and local-daemon sessions

## Validation

- `just test -p codex-tui external_agent_config_migration` (10 passed)
- manually exercised an isolated TUI fixture with existing
external-agent setup and session data using a fresh `CODEX_HOME`
- verified picker customization, plugin and session detection, import
completion, repeated invocation, and imported-session resume context
- the broader `just test -p codex-tui` run passed 2,805 tests, with 2
unrelated guardian feature-flag failures and 4 skipped tests

## Draft follow-ups

- review whether completion messaging should remain attached to the
initiating chat if the user switches chats during an import
- review shutdown semantics for an in-progress background import

stefanstokic-oaiandGitHub 636cc11398 [codex] remove blocking external agent migration flow (#27064)
## Why

External-agent import should be initiated deliberately instead of

startup flow before the replacement import experience is introduced
later in the stack.

## What changed

- remove the startup-blocking external-agent migration prompt
- remove the now-unused external migration feature gate
- remove the obsolete TUI app-server migration wrappers
- retain the dormant picker behind a module-scoped dead-code allowance
until the next stack item wires it back in
- keep normal TUI startup focused on entering Codex immediately

canvrno-oaiandGitHub 8a299fb704 fix: Prevent /review crash when entering Esc on steer message (#22879)
This changes the `/review` escape path so `Esc` no longer behaves like
the normal queued-follow-up interrupt flow while a review is running.
Steering is not currently supported in `/review` mode, without this
change users are able to attempt a steer but it leads to a crash (see
#22815). If the user has already tried to send additional guidance
during `/review`, the TUI now keeps the review running and shows a
warning that steer messages are not supported in that mode, while still
pointing users to `Ctrl+C` if they actually want to cancel. It also adds
regression coverage for the review-specific warning behavior. When users
do cancel with Ctrl+C during /review, the TUI now tolerates the
active-turn race that can happen during review handoff, and any queued
steer messages are restored to the composer instead of being discarded.

- Special-case `Esc` during an active `/review` when follow-up steer
input is pending or has already been deferred.
- Show a clear warning instead of interrupting the running review.
- Make the Ctrl+C cancel path during /review resilient to active-turn
races, while preserving any queued steer text by restoring it to the
composer.
- Add review-mode test coverage for the warning path.

## Testing

1. Start a `/review` with a diff large enough that the review stays
active for more than a few seconds.

2. While the review is still running, type a follow-up / steer message,
submit it, and then press `Esc`.
   Before: `Esc` causes the TUI to close abruptly.  
After: the review keeps running and the transcript shows a warning that
steer messages are not supported during `/review`, with guidance to use
`Ctrl+C` if you want to cancel.

3. Press `Ctrl+C` if you actually want to stop the review.  
Before: (after restarting the test since Pt. 2 crashed) this is the
intentional cancellation path.
After: this remains the intentional cancellation path, and any queued
follow-up steer text is restored to the composer instead of being lost.
   
## Note:
`/review` mode explicitly does not support steering at this time (as
noted in `turn_processer.rs`, if we want to explore that in the future
this code will need to be modified). This change keeps unsupported steer
attempts from crashing the TUI and preserves queued follow-up text if
the user cancels with Ctrl+C.

cooper-oaiandGitHub df7818c7d1 [codex-rs] support v2 personal access tokens (#25731)
## Summary

- add v2 personal access token support for `codex login
--with-access-token` and `CODEX_ACCESS_TOKEN`
- classify opaque `at-` tokens separately from legacy Agent Identity
JWTs
- hydrate required ChatGPT account metadata through AuthAPI
`/v1/user-auth-credential/whoami`
- use PATs directly as bearer tokens while preserving existing ChatGPT
account surfaces
- expose PAT-backed auth as the explicit `personalAccessToken`
app-server auth mode

## Implementation

PAT auth is intentionally small and stateless. Loading a PAT performs
one AuthAPI metadata request, stores the hydrated metadata in the
in-memory auth object, and redacts the secret from debug output. Legacy
Agent Identity JWT handling remains unchanged. The shared access-token
classifier lives in a private neutral module because it dispatches
between both credential types.

PAT hydration fails closed when AuthAPI omits any required metadata,
including email. Hydrated metadata is intentionally not persisted:
startup performs a live `whoami` preflight so revoked tokens or changed
account metadata are not accepted from a stale cache.

## Workspace restriction scope

This change intentionally does **not** apply
`forced_chatgpt_workspace_id` to PAT authentication. The setting is a
client-side config guardrail, not an authorization boundary, and PAT
does not currently require workspace-ID parity. The PAT login and
`CODEX_ACCESS_TOKEN` paths therefore validate through AuthAPI without
threading workspace-restriction state through access-token loading.
Existing workspace checks for non-PAT auth remain on their established
paths.

## App-server compatibility

The public app-server `AuthMode` is shared across v1 and v2, and
PAT-backed auth reports `personalAccessToken` through both APIs.
Following human review, this intentionally removes the temporary v1
compatibility mapping that reported PATs as `chatgpt`; the deprecated v1
API is kept in parity with v2 rather than maintaining a separate closed
enum. Clients with exhaustive auth-mode handling in either API version
must add the new case and should generally treat it as ChatGPT-backed
unless they need PAT-specific behavior.

The v1 auth-status response still omits the raw PAT when `includeToken`
is requested because that response cannot carry the account metadata
needed to reuse the credential safely. Persisted PAT auth also omits the
new enum value so older Codex builds can deserialize `auth.json` and
infer PAT auth from the credential field after a rollback.

## Validation

`UnderDevelopment`, disabled by default
- keep terminal visualization instructions inside the TUI package
- append them to existing developer instructions for TUI start, resume,
and fork flows only when enabled
- intentionally do not apply them to `codex exec`

## Rollout
Control behavior is unchanged. TUI dogfooders can enable
`terminal_visualization_instructions`; no default user receives the new
terminal-specific instructions.

The shared visualization-selection rule is supplied separately through
the `codex_proxy_model_3` Statsig layer for every target Codex model
slug in the gated cohort. This TUI feature determines how to render an
appropriate visualization on the terminal surface; the model-layer
treatment determines when to use one.

## Validation
- `cargo test -p codex-tui
terminal_visualization_instructions_are_gated_for_all_tui_thread_flows
--lib`
- `cargo test -p codex-features --lib`
- `cargo fmt --all -- --check`
- `git diff --check`
- GPT-5.4 and GPT-5.5 real prompt-pipeline smoke tests: both visualized
the positive mapping case, abstained on the negative route case, and
passed exact prompt-stack verification on CLI and App
- refreshed onto current `main` with a clean merge and reran the focused
validation

The full 53-probe all-model treatment comparison and requested
production coding evals remain rollout gates before broadening beyond
the initial employee cohort.

This PR remains open for normal human review.

Charlie MarshandGitHub 055c7a7c53 Speed up TUI startup by reusing plugin discovery (#26469)
## Summary

TUI startup loads related plugin data from `hooks/list`, session MCP
initialization, and plugin skill warmup. These paths repeated filesystem
discovery and emitted the same plugin warnings, while `hooks/list` and
account/model bootstrap ran serially.

This change:

- Reuses one immutable plugin load outcome across startup consumers.
- Keys the cache only on plugin-relevant configuration.
- Single-flights concurrent plugin loads and prevents invalidated loads
from repopulating the cache.
- Runs hook discovery and account/model bootstrap concurrently.
- Preserves configuration-migration ordering, hook review behavior, and
accurate startup telemetry.

In 10 alternating release-build launches in the Ruff repository with the
existing `~/.codex` configuration, median time to the first editable
composer decreased from 833ms to 504ms. The branch was faster in 9 of 10
pairs, with a paired median improvement of 312ms.

pakrym-oaiandGitHub 76c0a5379c Make runtime workspace roots absolute in app-server API (#26552)
Stacked on #26532.

## Why

#26532 moves cwd normalization to the app-server/core boundary.
`runtimeWorkspaceRoots` still accepted raw paths in v2 requests and in
`ConfigOverrides`, which left core responsible for interpreting those
roots later. This makes runtime workspace roots follow the same
absolute-path boundary as cwd.

## What

- Change v2 `runtimeWorkspaceRoots` request fields for `thread/start`,
`thread/resume`, `thread/fork`, and `turn/start` to `AbsolutePathBuf`.
- Deduplicate already-absolute runtime roots in app-server handlers and
pass them through `ConfigOverrides.workspace_roots` as
`AbsolutePathBuf`.
- Update TUI and exec client request builders to pass absolute runtime
roots directly.
- Update app-server docs, schema fixtures, and focused tests for
absolute runtime roots.

## Testing

- `just test -p codex-app-server-protocol`
- `just test -p codex-app-server runtime_workspace_roots`
- `just test -p codex-core
session_permission_profile_rebinds_runtime_workspace_roots`

Ahmed IbrahimandGitHub 8ac304c299 [codex] Support model-defined reasoning efforts (#26444)
## Summary
- accept non-empty model-defined reasoning effort values while
preserving built-in effort behavior
- propagate the non-Copy effort type through core, app-server, TUI,
telemetry, and persistence call sites
- preserve string wire encoding and expose an open-string schema for
clients
- update model selection and shortcut behavior for model-advertised
effort values

## Root cause
`ReasoningEffort` gained a string-backed custom variant, so it could no
longer implement `Copy` or rely on derived closed-enum serialization.
Existing consumers still moved effort values from shared references and
assumed a fixed built-in value set.

## Validation
- `just fmt`
- Local tests and compilation were not run per request; relying on CI.

efrazer-oaiandGitHub c8e5db16c9 feat: show enterprise monthly credit limits in status (#24812)
## 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.

Owen LinandGitHub 11e0f3d3ae app-server: remove experimental persist_extended_history bool flag (#25712)
## 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

Owen LinandGitHub cf0911076f store and expose parent_thread_id on Threads (#25113)
## 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.

Eric TrautandGitHub 3e7baa00e4 Add thread archive CLI commands (#25021)
## 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.
2026-05-29 23:37:26 -07:00
Eric TrautandGitHub 36cd36626d Add /archive slash command (#25027)
## Why

TUI users can archive saved sessions from other surfaces, but there is
no in-session command for archiving the active session. Since archiving
the active session also exits the TUI, the command should ask for
explicit confirmation instead of firing immediately.

I'm also working on [a companion
PR](https://github.com/openai/codex/pull/25021) that adds `codex
archive` and `codex unarchive` top-level CLI commands.

## What changed

- Adds a new `/archive` slash command described as `archive this session
and exit`.
- Shows a confirmation dialog with `No, don't archive` selected first
and `Yes, archive and exit` as the explicit action.
- On confirmation, calls the existing `thread/archive` app-server RPC
for the active main session and exits after success.
- Keeps `/archive` disabled while a task is running and unavailable in
side conversations.

## Verification

Added focused TUI coverage for the `/archive` confirmation flow,
disabled-while-task-running behavior, and the `/ar` slash-command popup
snapshot.

Alexi ChristakisandGitHub e92c952b2e [codex] Add user input client ids (#24653)
## 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.

Brent TrautandGitHub 2a1158b8e2 feat(app-server): include turns page on thread resume (#23534)
## 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`.

pakrym-oaiandGitHub 768848ab6f Add experimental turn additional context (#24154)
## 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.

Eric TrautandGitHub 5fb5e47767 Respect hook trust bypass during TUI startup (#24317)
Fixes #24093.

## Why

`--dangerously-bypass-hook-trust` is a supported CLI flag intended for
headless or automated runs where enabled hooks should be allowed to run
without requiring persisted trust. In the TUI, startup hook review still
opened whenever hooks looked untrusted, so a launch using the bypass
could block on the interactive "Hooks need review" prompt.

The tricky case is persistent app-server resume: a resume may attach to
an already-running thread, where resume config overrides are ignored. In
that path, hiding the startup review would be wrong because the existing
hook engine may still filter untrusted hooks.

## What Changed

- Startup hook review now skips the prompt only when hook trust bypass
is actually safe for that launch.
- The TUI forwards `bypass_hook_trust` through the app-server request
config for fresh thread start/resume/fork paths, and the app-server
applies it as a runtime-only `ConfigOverrides` value rather than
treating it like a `config.toml` setting.
- Persistent app-server resumes keep the startup review prompt so users
still have a chance to trust hooks when the running thread cannot
receive the bypass override.

## Verification

- Added focused coverage for startup hook review with and without
`bypass_hook_trust`.
- Extended existing TUI/app-server config override tests to cover
forwarding and applying `bypass_hook_trust`.

Eric TrautandGitHub 913270a689 Show remote connection details in /status (#24420)
## Summary

Fixes #24411.

`/status` currently has no way to show when the TUI is talking to Codex
through a remote transport. That makes embedded local sessions, local
daemon sessions, and true remote sessions look the same, and it hides
the remote server version when debugging connection-specific behavior.

This PR adds a single `Remote` row for non-embedded connections only.
The row shows the sanitized connection address and a dimmed version
parenthetical, preserving the existing status output for embedded local
sessions.

jif-oaiandGitHub 2c6605ab35 config: remove legacy profile write paths (#24055)
## Why

[#23883](https://github.com/openai/codex/pull/23883) moved the
user-facing `--profile` flag onto profile v2 and
[#23886](https://github.com/openai/codex/pull/23886) removed CLI
forwarding for the legacy profile-v1 path. Core and TUI config
persistence still carried `active_profile` and
`ConfigEditsBuilder::with_profile`, which let later writes continue
targeting legacy `[profiles.<name>]` tables after profile selection
moved to profile-v2 config files.

## What

- Remove legacy profile routing from
[`ConfigEditsBuilder`](https://github.com/openai/codex/blob/4b38e9c22e762261d7f7eef49d8a21792e241a06/codex-rs/core/src/config/edit.rs#L1064-L1294),
so core config edits no longer carry `with_profile` or infer
`[profiles.*]` write targets from a `profile` key.
- Drop `active_profile` plumbing from runtime `Config`, TUI
startup/state, app-server config override forwarding, and Windows
sandbox setup persistence.
- Make app-server-backed TUI config edits use unscoped model,
service-tier, feature, Auto-review, plan-mode, and Windows sandbox paths
through
[`tui/src/config_update.rs`](https://github.com/openai/codex/blob/4b38e9c22e762261d7f7eef49d8a21792e241a06/codex-rs/tui/src/config_update.rs#L43-L112).
- Update config edit coverage so legacy `profile` state stays untouched
by direct model writes, and remove tests whose only contract was the
deleted profile-scoped persistence path.

## Testing

- Not run locally.

Shijie RaoandGitHub 370b13afc9 Honor client-resolved service tier defaults (#23537)
## Why

Model catalog responses can now advertise a nullable
`default_service_tier` for each model. Codex needs to preserve three
distinct states all the way from config/app-server inputs to inference:

- no explicit service tier, so the client may apply the current model
catalog default when FastMode is enabled
- explicit `default`, meaning the user intentionally wants standard
routing
- explicit catalog tier ids such as `priority`, `flex`, or future tiers

Keeping those states distinct prevents the UI from showing one tier
while core sends another, especially after model switches or app-server
`thread/start` / `turn/start` updates.

## What Changed

- Plumbed `default_service_tier` through model catalog protocol types,
app-server model responses, generated schemas, model cache fixtures, and
provider/model-manager conversions.
- Added the request-only `default` service tier sentinel and normalized
legacy config spelling so `fast` in `config.toml` still materializes as
the runtime/request id `priority`.
- Moved catalog default resolution to the TUI/client side, including
recomputing the effective service tier when model/FastMode-dependent
surfaces change.
- Updated app-server thread lifecycle config construction so
`serviceTier: null` preserves explicit standard-routing intent by
mapping to `default` instead of internal `None`.
- Kept core responsible for validating explicit tiers against the
current model and stripping `default` before `/v1/responses`, without
applying catalog defaults itself.

Eric TrautandGitHub edc48e4612 Sync TUI thread settings through app server (#23507)
Builds on #23502.

## Why

#23502 adds the app-server `thread/settings/update` API and matching
`thread/settings/updated` notification. The TUI already lets users
change thread-scoped settings such as model, reasoning effort, service
tier, approvals, permissions, personality, and collaboration mode, but
those updates need to flow through the app server so embedded and
connected clients observe the same thread state.

This is a rework (simplification) of PR
https://github.com/openai/codex/pull/22510. It has the same
functionality, but the underlying `thread/settings/update` api is now
simpler in that it no longer returns the effective settings as a
response. Now, clients receive the effective settings only through the
`thread/settings/updated` notification.

## What Changed

This updates the TUI to send `thread/settings/update` whenever those
thread-scoped settings change and to treat the RPC response as the
authoritative acknowledgement. It also routes `thread/settings/updated`
notifications back into cached session state and the visible chat widget
so active and inactive threads stay in sync after app-server-originated
changes.

The implementation is kept to the TUI layer: settings conversion and
merge logic live under `codex-rs/tui/src/app/thread_settings.rs`, with
dispatch/routing hooks in the existing app and chat widget paths.

## Verification

I manually tested using `codex app-server --listen unix://` and then
launching two copies of the TUI that use the same local app server. I
then resumed the same thread on both and verified that changes like plan
mode, fast mode, model, reasoning effort, etc. are reflected "live" in
the second client when modified in the first and vice versa.

Eric TrautandGitHub c0f7e1b99f [2 of 2] Start fresh TUI thread in background (#23176)
## Why

After the terminal-probe work in #23175, fresh-session startup still
waits for `thread/start` before the chat input can become usable. The
chat widget already has the machinery to hold early submissions until a
session is configured, so fresh `thread/start` does not need to stay on
the input-ready hot path.

Refs #16335.

## What

This PR starts fresh app-server threads in a background task, reports
completion through a startup app event, and attaches the primary session
once `thread/start` returns. Resume and fork startup paths remain
synchronous.

## Benchmark

In the local pty startup benchmark, this PR's pre-optimization base
branch, #23175, measured about 152ms median from launch to accepted chat
input. The stacked result measured about 66ms median, for an approximate
additional savings of 85-95ms. For broader context, the original `main`
baseline before either startup optimization was about 250.5ms median. We
also measured Codex 0.117.0 on the same machine at about 64.6ms median,
so the stacked branch is back in the old-startup-time range.

canvrno-oaiandGitHub 27c4c67b15 Fix: TUI starting in wrong CWD (#23538)
This fixes a regression wher codex could start in the wrong directory
when a live local app-server socket was present. The issue was that
implicit local socket reuse was being treated like an explicit remote
workspace session, which dropped the invoking cwd unless --cd was
passed.

The change separates local socket transport from true remote workspace
semantics.
- Plain local startup keeps local cwd, trust, resume, picker, and
config-refresh behavior.
- Explicit --remote keeps the existing remote cwd behavior.
- Added coverage for launch target selection and local-session
filtering/cwd behavior.

Steps to test:
- Start a local app-server from a different directory than the repo you
want to use.
  - Launch codex from a project/worktree without --cd.
- Confirm the session starts in the invoking directory, not the
app-server process directory.
- Confirm explicit codex --remote ... still preserves existing remote
behavior.

Arun EswaraandGitHub d269aa2af9 Harden CLI rate limit window labels (#22929)
## Context

The CLI rate-limit surfaces previously described usage windows as fixed
5-hour and weekly limits. We want the CLI to display whatever supported
rate-limit period the server returns instead of assuming a 5-hour/1-week
pair. This supports generalized Codex rate-limit periods.

## Summary

- Formats CLI rate-limit warning/status labels only for the supported
returned window durations: approximate 5h, daily, weekly, monthly, and
annual.
- Uses generic fallback copy when a primary or secondary window has no
duration, so missing secondary protection data does not produce stale
weekly copy.
- Uses generic fallback copy for unsupported window durations instead of
adding arbitrary hourly, multi-day, multi-week, or multi-year labels.
- Updates status line and terminal title setup descriptions/previews to
talk about primary/secondary usage limits rather than fixed 5h/weekly
limits.
- Adds rendered insta snapshot coverage for the updated rate-limit
status surfaces and `/status` fallback labels.

## Tests
Tested locally:
- one primary window
- one secondary window
- primary and secondary window

Michael BolinandGitHub 3fd79b7986 app-server: use profile ids in v2 permission params (#23360)
## Why

The v2 app-server permission profile fields are experimental, but the
previous migration kept a legacy object payload for profile selection.
That made clients aware of server-owned `activePermissionProfile`
metadata such as `extends`, and it kept a
`legacy_additional_writable_roots` path even though
`runtimeWorkspaceRoots` now owns runtime workspace-root selection.

This PR makes the client contract match the intended model: clients
select a permission profile by id, and the server resolves and reports
active profile provenance in response payloads.

Follow-up to #22611.

## What Changed

- Changed `thread/start`, `thread/resume`, `thread/fork`, and
`turn/start` permission profile selection to plain profile id strings.
- Changed `command/exec.permissionProfile` to a plain profile id string
for the same client/server ownership split.
- Removed `PermissionProfileSelectionParams` and the legacy `{ type:
"profile", modifications: [...] }` compatibility deserializer.
- Updated app-server, TUI, and `codex exec` call sites to send only ids,
while keeping `activePermissionProfile` as server response metadata.
- Updated app-server docs and schema fixtures for the revised
`command/exec.permissionProfile` shape.

## Verification

- `cargo test -p codex-app-server-protocol`
- `RUST_MIN_STACK=8388608 cargo test -p codex-app-server`
- `cargo test -p codex-exec`
- `RUST_MIN_STACK=8388608 cargo test -p codex-tui`

Michael BolinandGitHub 9025550709 app-server-protocol: remove PermissionProfile from API (#22924)
## Why

The app server API should expose permission profile identity, not the
lower-level runtime permission model. `PermissionProfile` is the
compiled sandbox/network representation that the server uses internally;
exposing it through app-server-protocol forces clients to understand
details that should remain implementation-level.

The API boundary should prefer `ActivePermissionProfile`: a stable
profile id, plus future parent-profile metadata, that clients can pass
back when they want to select the same active permissions. This also
avoids schema generation collisions between the app-server v2 API type
space and the core protocol model.

Incidentally, while PR makes a number of changes to `command/exec`, note
that we are hoping to deprecate this API in favor of `process/spawn`, so
we don't need to be too finicky about these changes.

## What Changed

- Removed `PermissionProfile` from the app-server-protocol API surface,
including generated schema and TypeScript exports.
- Changed `CommandExecParams.permissionProfile` to
`ActivePermissionProfile`.
- Resolve command exec profile ids through `ConfigManager` for the
command cwd, matching turn override selection semantics.
- Updated downstream TUI tests/helpers to use core permission types
directly instead of app-server-protocol `PermissionProfile` shims.

Michael BolinandGitHub 83bbb4f326 app-server: stop returning thread permission profiles (#22792)
## Why

The app-server thread lifecycle API should no longer expose the full
`PermissionProfile` value. After the permissions-profile migration,
clients should round-trip only the active profile identity through
`activePermissionProfile` and `permissions` when that identity is known.

The full profile is server-side config. Treating a response-derived
legacy sandbox projection as a new local profile can lose named-profile
restrictions and accidentally widen permissions on the next turn. The
legacy `sandbox` response field remains only as the
compatibility/display fallback.

## What Changed

- Removed `permissionProfile` from `ThreadStartResponse`,
`ThreadResumeResponse`, and `ThreadForkResponse`.
- Stopped populating that field in app-server thread start/resume/fork
responses.
- Updated embedded exec/TUI response mapping to derive display
permission state from local config or the legacy sandbox fallback
instead of a response profile value.
- Added a TUI turn override shape that distinguishes preserving server
permissions, selecting an active profile id, and sending a legacy
sandbox for an explicit local override.
- Preserved remote app-server permissions across turns by sending
`permissions` only when an `activePermissionProfile` id is known, and
otherwise sending no sandbox override unless the user selected a local
override.
- Kept embedded `thread/resume` hydration server-authored when
`activePermissionProfile` is absent, which matches the live-thread
attach path where the server ignores requested overrides.
- Updated the app-server README to remove the obsolete lifecycle
response `permissionProfile` reference. The remaining
`permissionProfile` README references are request-side permission
overrides.
- Regenerated app-server JSON schema and TypeScript fixtures.
- Kept the generated typed response enum exempt from
`large_enum_variant`, matching the existing payload enum exemption after
the lifecycle response variants shrank.

## How To Review

Start with `codex-rs/app-server-protocol/src/protocol/v2/thread.rs` to
confirm the response shape, then check the response construction in
`codex-rs/app-server/src/request_processors`. The generated schema and
TypeScript fixture changes are mechanical follow-through from the
protocol removal.

The TUI behavior is the delicate part: review
`codex-rs/tui/src/app_server_session.rs` for response hydration and
turn-start override projection, then
`codex-rs/tui/src/app/thread_routing.rs` for the decision about whether
the next turn should preserve the server snapshot, send an active
profile id, or send a legacy sandbox for an explicit local override.

Michael BolinandGitHub 8a5306ff88 app-server: use permission ids and runtime workspace roots (#22611)
## Why

This PR builds on [#22610](https://github.com/openai/codex/pull/22610)
and is the app-server side of the migration from mutable per-turn
`SandboxPolicy` replacement toward selecting immutable permission
profiles by id plus mutable runtime workspace roots.

Once permission profiles can carry their own immutable
`workspace_roots`, app-server no longer needs to mutate the selected
`PermissionProfile` just to represent thread-specific filesystem
context. The mutable part now lives on the thread as explicit
`runtimeWorkspaceRoots`, while `:workspace_roots` remains symbolic until
the sandbox is realized for a turn.

## What Changed

- Replaced the v2 permission-selection wrapper surface with plain
profile ids for `thread/start`, `thread/resume`, `thread/fork`, and
`turn/start`.
- Removed the API surface for profile modifications
(`PermissionProfileSelectionParams`,
`PermissionProfileModificationParams`,
`ActivePermissionProfileModification`).
- Added experimental `runtimeWorkspaceRoots` fields to the thread
lifecycle and turn-start APIs.
- Threaded runtime workspace roots through core session/thread
snapshots, turn overrides, app-server request handling, and command
execution permission resolution.
- Kept session permission state symbolic so later runtime root updates
and cwd-only implicit-root retargeting rebind `:workspace_roots`
correctly.
- Updated the embedded clients just enough to send and restore the new
thread state.
- Refreshed the generated schema/TypeScript artifacts and the app-server
README to match the new contract.

## Verification

Targeted coverage for this layer lives in:

- `codex-rs/app-server-protocol/src/protocol/v2/tests.rs`
- `codex-rs/app-server/tests/suite/v2/thread_start.rs`
- `codex-rs/app-server/tests/suite/v2/thread_resume.rs`
- `codex-rs/app-server/tests/suite/v2/turn_start.rs`
- `codex-rs/core/src/session/tests.rs`

The key regression checks exercise that:

- `runtimeWorkspaceRoots` resolve against the effective cwd on thread
start.
- Profile-declared workspace roots are excluded from the runtime
workspace roots returned by app-server.
- A turn-level runtime workspace-root update persists onto the thread
and is returned by `thread/resume`.
- A named permission profile selected on one turn remains symbolic so a
later runtime-root-only turn update changes the actual sandbox writes.
- A cwd-only turn update retargets the implicit runtime cwd root while
preserving additional runtime roots.
- The protocol fixtures and generated client artifacts stay in sync with
the string-based permission selection contract.

Michael BolinandGitHub c25d905f61 permissions: support workspace roots in profiles (#22610)
## Why

This is the configuration/model half of the alternative permissions
migration we discussed as a comparison point for
[#22401](https://github.com/openai/codex/pull/22401) and
[#22402](https://github.com/openai/codex/pull/22402).

The old `workspace-write` model mixes three concerns that we want to
keep separate:
- reusable profile rules that should stay immutable once selected
- user/runtime workspace roots from `cwd`, `--add-dir`, and legacy
workspace-write config
- internal Codex writable roots such as memories, which should not be
shown as user workspace roots

This PR gives permission profiles first-class `workspace_roots` so users
can opt multiple repositories into the same `:workspace_roots` rules
without using broad absolute-path write grants. It also starts
separating the raw selected profile from the effective runtime profile
by making `Permissions` expose explicit accessors instead of public
mutable fields.

A representative `config.toml` looks like this:

```toml
default_permissions = "dev"

[permissions.dev.workspace_roots]
"~/code/openai" = true
"~/code/developers-website" = true

[permissions.dev.filesystem.":workspace_roots"]
"." = "write"
".codex" = "read"
".git" = "read"
".vscode" = "read"
```

If Codex starts in `~/code/codex` with that profile selected, the
effective workspace-root set becomes:
- `~/code/codex` from the runtime `cwd`
- `~/code/openai` from the profile
- `~/code/developers-website` from the profile

The `:workspace_roots` rules are materialized across each root, so
`.git`, `.codex`, and `.vscode` stay scoped the same way everywhere.
Runtime additions such as `--add-dir` can still layer on later stack
entries without mutating the selected profile.

## Stack Shape

This PR intentionally stops before the profile-identity cleanup in
[#22683](https://github.com/openai/codex/pull/22683) so the base review
stays focused on config loading, workspace-root materialization, and
compatibility with legacy `workspace-write`.

The representation in this PR is therefore transitional: `Permissions`
carries enough state to distinguish the raw constrained profile from the
effective runtime profile, and there are still call sites that must keep
the active profile identity and constrained profile value in sync. The
follow-up PR replaces that with a single resolved profile state
(`ResolvedPermissionProfile` / `PermissionProfileState`) that keeps the
profile id, immutable `PermissionProfile`, and profile-declared
workspace roots together. That follow-up removes APIs such as
`set_constrained_permission_profile_with_active_profile()` where
separate arguments could drift out of sync.

Downstream PRs then build on this base to switch app-server turn updates
to profile ids plus runtime workspace roots and to finish the
user-visible summary behavior. Reviewers should judge this PR as the
workspace-roots foundation, not as the final in-memory shape of selected
permission profiles.

## Review Guide

Suggested review order:

1. Start with `codex-rs/core/src/config/mod.rs`.
This is the main shape change in the base slice. `Permissions` now
stores a private raw `Constrained<PermissionProfile>` plus runtime
`workspace_roots`. Callers use `permission_profile()` when they need the
raw constrained value and `effective_permission_profile()` when they
need a materialized runtime profile. As noted above,
[#22683](https://github.com/openai/codex/pull/22683) replaces this
transitional shape with a resolved profile state that keeps identity and
profile data together.

2. Review `codex-rs/config/src/permissions_toml.rs` and
`codex-rs/core/src/config/permissions.rs`.
These add `[permissions.<id>.workspace_roots]`, resolve enabled entries
relative to the policy cwd, and keep `:workspace_roots` deny-read glob
patterns symbolic until the actual roots are known.

3. Review `codex-rs/protocol/src/permissions.rs` and
`codex-rs/protocol/src/models.rs`.
These add the policy/profile materialization helpers that expand exact
`:workspace_roots` entries and scoped deny-read globs over every
workspace root. This is also where `ActivePermissionProfileModification`
is removed from the core model.

4. Review the legacy bridge in
`Config::load_from_base_config_with_overrides` and
`Config::set_legacy_sandbox_policy`.
This is where legacy `workspace-write` roots become runtime workspace
roots, while Codex internal writable roots stay internal and do not
appear as user-facing workspace roots.

5. Then skim downstream call sites.
The interesting pattern is raw-vs-effective access: state/proxy/bwrap
paths keep the raw constrained profile, while execution, summaries, and
user-visible status use the effective profile and workspace-root list.

## What Changed

- added `[permissions.<id>.workspace_roots]` to the config model and
schema
- added runtime `workspace_roots` state to `Config`/`Permissions` and
`ConfigOverrides`
- made `Permissions` profile fields private and replaced direct mutation
with accessors/setters
- added `PermissionProfile` and `FileSystemSandboxPolicy` helpers for
materializing `:workspace_roots` exact paths and deny-read globs across
all roots
- moved legacy additional writable roots into runtime workspace-root
state instead of active profile modifications
- removed `ActivePermissionProfileModification` and its app-server
protocol/schema export
- updated sandbox/status summary paths so internal writable roots are
not reported as user workspace roots

## Verification Strategy

The targeted tests cover the behavior at the layers where regressions
are most likely:
- `codex-rs/core/src/config/config_tests.rs` verifies config loading,
legacy workspace-root seeding, effective profile materialization, and
memory-root handling.
- `codex-rs/core/src/config/permissions_tests.rs` verifies profile
`workspace_roots` parsing and `:workspace_roots` scoped/glob
compilation.
- `codex-rs/protocol/src/permissions.rs` unit tests verify exact and
glob materialization over multiple workspace roots.
- `codex-rs/tui/src/status/tests.rs` and
`codex-rs/utils/sandbox-summary/src/sandbox_summary.rs` verify the
user-facing summaries show effective workspace roots and hide internal
writes.

I also ran `cargo check --tests` locally after the latest stack refresh
to catch cross-crate API breakage from the private-field/accessor
changes.

Michael BolinandGitHub 01d93fd9fc permissions: canonicalize workspace_roots and danger-full-access names (#22624)
## Why

This is a small precursor to the larger permissions-migration work. Both
the comparison stack in
[#22401](https://github.com/openai/codex/pull/22401) /
[#22402](https://github.com/openai/codex/pull/22402) and the alternate
stack in [#22610](https://github.com/openai/codex/pull/22610) /
[#22611](https://github.com/openai/codex/pull/22611) /
[#22612](https://github.com/openai/codex/pull/22612) are easier to
review if the terminology is already settled underneath them.

Because `:project_roots` and `:danger-no-sandbox` have not shipped as
stable user-facing surface area, carrying them forward as aliases would
just add more migration logic to the later stacks. This PR removes that
ambiguity now so the follow-on work can rely on one spelling for each
built-in concept.

## What Changed

- renamed the config-facing special filesystem key from `:project_roots`
to `:workspace_roots`
- dropped unpublished `:project_roots` parsing support in
`core/src/config/permissions.rs`, so new config only recognizes
`:workspace_roots`
- renamed the built-in full-access permission profile id from
`:danger-no-sandbox` to `:danger-full-access`
- dropped unpublished `:danger-no-sandbox` support entirely, including
the old active-profile canonicalization path, and added explicit
rejection coverage for the legacy id
- introduced shared built-in permission-profile id constants in
`codex-rs/protocol/src/models.rs`
- updated `core`, `app-server`, and `tui` call sites that special-case
built-in profiles to use the shared constants and canonical ids
- updated tests and the Linux sandbox README to use `:workspace_roots` /
`:danger-full-access`

## Verification

I focused verification on the three places this rename can regress:
config parsing, active-profile identity surfaced back out of `core`, and
user/server call sites that special-case built-in profiles.

Eric TrautandGitHub c03eb20d8d Fix side conversation config inheritance (#22106)
Addresses #22101

## Why

Side conversations are ephemeral forks of the active thread, but `/side`
was building its fork config from the app-level config after refreshing
it from disk. If the parent thread had runtime settings that differed
from the current persisted defaults, such as a changed model, reasoning
effort, permissions, reviewer, or fast-mode selection, the side
conversation could start with different behavior than its parent.

## What changed

- Build side fork config from the active parent `ChatWidget` config,
then overlay the parent thread's effective model, reasoning effort,
service tier, and fast-mode opt-out state.
- Forward model reasoning summary, verbosity, personality, web search
mode, and service-tier overrides through TUI app-server
start/resume/fork lifecycle params.
- Add focused tests for parent runtime inheritance, side developer
guardrail preservation, and lifecycle param forwarding.

rhan-oaiandGitHub 21295f47e2 [codex-tui] pass thread source for tui threads (#21401)
## Summary
- mark TUI-created thread starts and forks with explicit `thread_source
= user`
- add focused coverage for embedded and remote lifecycle request
builders

## Why
Thread analytics now consume an explicit thread-level source
classification instead of inferring it from `session_source`. The TUI
still omitted that field, so TUI-created interactive threads would
continue to land as `null` even after the new analytics plumbing
shipped.

## Validation

pakrym-oaiandGitHub 2004173cd7 Move message history out of core (#21278)
## Why

Message history was implemented inside `codex-core` and surfaced through
core protocol ops and `SessionConfiguredEvent` fields even though the
current consumer is TUI-local prompt recall. That made core own UI
history persistence and exposed `history_log_id` / `history_entry_count`
through surfaces that app-server and other clients do not need.

This change moves message history persistence out of core and keeps the
recall plumbing local to the TUI.

## What changed

- Added a new `codex-message-history` crate for appending, looking up,
trimming, and reading metadata from `history.jsonl`.
- Removed core protocol history ops/events: `AddToHistory`,
`GetHistoryEntryRequest`, and `GetHistoryEntryResponse`.
- Removed `history_log_id` and `history_entry_count` from
`SessionConfiguredEvent` and updated exec/MCP/test fixtures accordingly.
- Updated the TUI to dispatch local app events for message-history
append/lookup and keep its persistent-history metadata in TUI session
state.

## Validation

- `cargo test -p codex-message-history -p codex-protocol`
- `cargo test -p codex-exec event_processor_with_json_output`
- `cargo test -p codex-mcp-server outgoing_message`

jif-oaiandGitHub 5ecff05196 feat(app-server): move v2 sessionId onto Thread (#21336)
## Why

`session_id` and `thread_id` are separate identities after #20437, but
app-server only surfaced `sessionId` on the `thread/start`,
`thread/resume`, and `thread/fork` response envelopes. Other
thread-bearing surfaces such as `thread/list`, `thread/read`,
`thread/started`, `thread/rollback`, `thread/metadata/update`, and
`thread/unarchive` either lacked the grouping key or forced clients to
special-case those three responses.

Making `sessionId` part of the reusable `Thread` payload gives every v2
API surface one place to expose session-tree identity.

## Mental model
  1. thread.sessionId lives on `Thread`
2. It is a view/runtime identity for the current live session tree, not
durable stored lineage metadata
3. When app-server has a live loaded thread, it copies the real value
from core’s session_configured.session_id
4. When it only has stored/unloaded data, it falls back to
thread.sessionId = thread.id

## What changed

- Added `sessionId` to the v2
[`Thread`](https://github.com/openai/codex/blob/8fc9e9b4cf81b6f61d432e71f1eb266f6f104b63/codex-rs/app-server-protocol/src/protocol/v2/thread_data.rs#L105-L109).
- Removed the duplicate top-level `sessionId` fields from
`thread/start`, `thread/resume`, and `thread/fork`; clients should now
read `response.thread.sessionId`.
- Populated `thread.sessionId` when building live thread responses,
replaying loaded threads, and returning stored-thread summaries so the
field is present across start, resume, fork, list, read, rollback,
metadata-update, unarchive, and `thread/started` paths. See
[`load_thread_from_resume_source_or_send_internal`](https://github.com/openai/codex/blob/8fc9e9b4cf81b6f61d432e71f1eb266f6f104b63/codex-rs/app-server/src/request_processors/thread_processor.rs#L2824-L2918)
and
[`thread_from_stored_thread`](https://github.com/openai/codex/blob/8fc9e9b4cf81b6f61d432e71f1eb266f6f104b63/codex-rs/app-server/src/request_processors/thread_processor.rs#L3671-L3719).
- Preserved the stored-thread fallback: if a thread has not been loaded
into a live session tree yet, `thread.sessionId` falls back to
`thread.id`; once the thread is live again, the field reports the active
session tree root.
