Owen LinandGitHub 5267e805fb feat(app-server): add history_mode to thread (#29927)
## Description

This PR adds a new `historyMode = "legacy" | "paginated"` to `Thread`.
This will be stored in `SessionMeta` in the JSONL rollout file and as a
new column in the SQLite thread_metadata table, and exposed on
`thread/start` and on the `Thread` object in app-server.

## What changed

- Added canonical `ThreadHistoryMode` with `legacy` and `paginated`,
defaulting old and new SessionMeta to `legacy`.
- Carried `history_mode` through core session config, ThreadStore stored
metadata, local/in-memory stores, rollout metadata extraction, and the
existing SQLite `threads` table.
- Added experimental `historyMode` to app-server v2 `Thread` and
`thread/start`.
- Made paginated stored threads metadata-discoverable but unsupported
for legacy full-history reads, `load_history`, live resume, and create
paths.
- Regenerated app-server schema fixtures and added
protocol/state/thread-store/app-server coverage for persistence and
fail-closed behavior.

## Compatibility floor
Because users may be running various versions of Codex binaries on the
same machine (TUI, Codex App, etc.), we will need to establish a
compatibility floor for upcoming paginated threads, which will change
how thread storage reads and writes work.

The overall plan here:
```
Release N:
- Add historyMode to SessionMeta / Thread / SQLite metadata.
- Teach binaries to understand paginated threads.
- If a binary sees `historyMode="paginated"` but does not support the paginated contract, it refuses to resume/mutate the thread.
- Default remains `"legacy"`.

Release N+1:
- First-party clients start opting into paginated threads where appropriate.
- Internal dogfood / staged rollout.
- Measure old-client usage and paginated-thread unsupported errors.

Release N+2:
- Only after Release N+ is overwhelmingly deployed, make paginated the default.
- Accept that a small tail of N-1-or-older binaries may not understand paginated threads.
```

The important behavior change is fail-closed handling for a binary that
encounters a persisted `paginated` thread before it knows how to fully
support paginated history. In app-server, if a thread is `paginated`, we
will:

- allow metadata-only discovery paths like `thread/list` and
`thread/read(includeTurns=false)`, so clients can still see the thread
and inspect its `historyMode`
- reject legacy full-history/live-thread paths like
`thread/read(includeTurns=true)` and `thread/resume` with an unsupported
JSON-RPC error
- avoid silently treating an unknown or future `historyMode` as `legacy`

Under the hood, the ThreadStore layer also rejects legacy operations
that would need to load or replay the full thread history for a
paginated thread. That gives us the behavior we want for Release N:
future paginated threads are visible, but this binary fails closed
instead of trying to operate on them as if they were legacy threads.

Brent TrautandGitHub 8057603d0c feat(app-server): list descendant threads by ancestor (#29591)
## Why

`thread/list` can filter direct children with `parentThreadId`, but
clients cannot request an entire spawned subtree. Discovering every
descendant requires repeated client-side requests and gives up the
database's existing filtering and pagination path.

## What changed

Experimental clients can use `ancestorThreadId` to return strict
descendants at any depth while `parentThreadId` retains its direct-child
meaning. The filters are mutually exclusive, the ancestor is excluded,
and every result preserves its immediate `parentThreadId` so callers can
reconstruct the tree.

## How it works

- **Explicit relationship:** Internal list parameters distinguish direct
children from transitive descendants without changing the meaning of
`parentThreadId`.
- **Existing graph:** Persisted parent-child spawn edges remain the
source of truth, so descendant lookup needs no schema migration or
ancestry cache.
- **Indexed traversal:** A recursive SQLite query starts from the
parent-edge index, walks each generation, and applies thread filters,
sorting, and cursor pagination in the same database request.
- **Reconstructable results:** The response stays flat and normally
ordered while carrying each descendant's immediate parent.

## Verification

Ran 550 tests across the protocol, state, rollout, and thread-store
crates, then reran the four focused state, store, and app-server
descendant-listing tests after the final diff reduction. Scoped Clippy
and formatting checks passed. Stable and experimental schema generation
was checked; the stable fixtures remain unchanged while the experimental
schema includes the new field.

canvrno-oaiandGitHub 1659c4a629 PAC 2 - Add shared auth system proxy contract (#26707)
## Summary

Stacked on #26706.

Adds the shared auth/system-proxy contract that later platform resolver
PRs plug into. This PR moves Codex-owned auth and startup HTTP clients
through a common route-aware boundary, but does not yet add Windows or
macOS system proxy resolution.

The default path remains unchanged when `respect_system_proxy` is absent
or disabled.

## Implementation

- Adds `codex-client/src/outbound_proxy.rs` with the shared
route-selection model:
  - `OutboundProxyConfig`;
  - `ClientRouteClass`;
  - `RouteFailureClass`;
  - `build_reqwest_client_for_route`.
- Preserves the existing reqwest/default-client behavior when no route
config is supplied.
- Uses the fixed MVP routing policy when route config is supplied:
platform system/PAC/WPAD discovery, then explicit env proxy variables,
then direct connection.
- Keeps platform-specific system discovery behind the shared client
boundary. This PR provides the contract and fallback behavior; later
resolver PRs plug in Windows and macOS discovery.
- Adds `login::AuthRouteConfig` so auth call sites depend on a small
policy type instead of platform resolver details.
- Maps the resolved `Config.respect_system_proxy` boolean into
`AuthRouteConfig` for auth-owned clients.
- Wires the route config through browser login, device-code login,
access-token login, login status, logout/revoke, token refresh, API-key
exchange, app-server account login, TUI/app startup, cloud-config
bootstrap, cloud tasks, plugin auth, and exec startup config loading.

## End-user behavior

- No behavior changes by default.
- When `respect_system_proxy = true`, auth-owned clients opt into the
shared route-aware client path.
- On platforms without a resolver implementation in this PR, system
discovery is unavailable and the route-aware path falls back to explicit
env proxy handling, then direct connection.
- Custom CA handling remains separate from proxy route selection and
still runs through the shared client builder.
- No proxy URLs, PAC contents, or resolved platform details are exposed
through the public config surface introduced here.

## Tests

Adds or updates coverage for:

- preserving default auth-client fallback behavior when no route config
is provided;
- injected environment-proxy fallback without mutating process
environment;
- existing login-server E2E flows using explicit `auth_route_config:
None` to guard unchanged default behavior;
- updated auth manager, login, logout, cloud-config, startup, and
plugin-auth call sites passing route config explicitly.

Shijie RaoandGitHub 7abfcf220b Expose thread-level multi-agent mode (#28792)
## Why

Once multi-agent mode can be selected per turn, clients also need to
choose the initial selection when creating a thread and observe that
selection through lifecycle and settings APIs.

The selected value is intentionally distinct from the effective
model-visible value: no client selection is represented as `null`, even
though an eligible multi-agent v2 turn derives `explicitRequestOnly` as
its effective default.

## What changed

- Add the optional experimental `thread/start.multiAgentMode` parameter
and pass it through thread creation.
- Preserve an omitted initial value as an unset selection rather than
eagerly storing `explicitRequestOnly`.
- Apply an explicit `thread/start` selection to the first turn through
the session configuration established at thread creation.
- Restore the latest persisted effective mode as the selected baseline
on cold resume when rollout history contains one.
- Inherit the optional selected mode from a loaded parent when creating
related runtime threads.
- Return the current selected `multiAgentMode` from `thread/start`,
`thread/resume`, `thread/fork`, and thread settings, using `null` when
no mode is selected.
- Keep lifecycle reporting independent from model capability and feature
eligibility; core turn construction remains responsible for calculating
and persisting the effective mode.

## Not covered

- Clearing an existing loaded-session selection back to unset through
`turn/start`; omitted or `null` currently retains the session's
selection.
- A TUI control, slash command, or `config.toml` preference.

## Verification

- `CARGO_INCREMENTAL=0 just test -p codex-app-server-protocol`
- `CARGO_INCREMENTAL=0 just test -p codex-app-server multi_agent_mode`

The focused app-server coverage verifies explicit `thread/start`
initialization, first-turn prompting, nullable reporting for an omitted
selection, and retention of selections that are not currently
runtime-eligible.

## Stack

Stacked on #28685. This PR contains only the thread initialization and
lifecycle/settings API layer.

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.

AdrianandGitHub ec848dde0e feat: opt ChatGPT auth into agent identity (#19049)
## Stack

This is PR 2 of the simplified HAI single-run-task stack:

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

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

## Summary

This PR adds the disabled-by-default path for normal ChatGPT-login Codex
sessions to obtain Agent Identity runtime auth through the Codex
backend. Existing Agent Identity JWT startup mode remains a separate
path and does not require the feature flag.

What changed:

- adds the experimental `use_agent_identity` feature flag and config
schema entry
- adds an explicit `AgentIdentityAuthPolicy` so call sites choose
`JwtOnly` or `ChatGptAuth` instead of passing a bare boolean
- stores standalone Agent Identity JWT credentials separately from
backend-registered Agent Identity records
- persists the registered Agent Identity record, private key, and single
run task id in `auth.json` so process restarts reuse the same identity
- derives the agent/task registration base URL from ChatGPT/Codex auth
config while keeping JWT JWKS lookup separate
- provisions and caches ChatGPT-derived Agent Identity runtime auth when
`use_agent_identity` is enabled
- reuses the shared run-task registration helper from PR1 rather than
adding a second task-registration path

This PR intentionally does not switch model inference over to
`AgentAssertion` auth. The provider-auth integration lands in the next
PR.

## Testing

- `just test -p codex-login`

765309d5a6 Emit Trusted MCP App Identity on Tool-Call Items (#27132)
## Summary

- Add optional `appContext` to app-server MCP tool-call items with
trusted `connectorId`, `linkId`, and `mcpAppResourceUri` metadata.
- Preserve that context across tool-call events, persisted history,
reconnects, and thread resume.
- Keep the deprecated top-level `mcpAppResourceUri` temporarily for
client migration.

The consumer contract is `{ appContext: { connectorId, linkId,
mcpAppResourceUri }, tool }`.

## Validation

- Full GitHub Actions suite passes, including CLA, Bazel tests, clippy,
release builds, and argument-comment lint.

rka-oaiandGitHub f4602b7516 Add app-server current-time impl (varlatency 3/n) (#28835)
## What

Server should request:

```
{
  "id": 42,
  "method": "currentTime/read",
  "params": {
    "threadId": "11111111-1111-1111-1111-aaaaafdc2c11"
  }
}
```

Client should respond with something like:

```rust
{
  "id": 42,
  "result": {
    "currentTimeAt": 1781717655
  }
}
```

## Why

Sessions configured with `clock_source = "external"` need a
thread-specific external time source before inference. The system clock
remains the default production provider.

Adam Perry @ OpenAIandGitHub 3931bc2bde unified-exec: retain PathUri in command events (#28780)
## Why

App-server must report command events containing foreign-platform paths
without changing existing client or rollout path-string formats.

## What changed

- retain `PathUri` through exec command begin/end events
- convert cwd values to `LegacyAppPathString` at the app-server
compatibility boundary
- drop command actions with foreign paths and log them
- serialize rollout-trace cwd values using their inferred native path
representation
- restore Wine coverage for retained Windows cwd values and successful
completion

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.

AdrianandGitHub d9e0551564 feat: add run task identity primitives (#19047)
## Stack

This is PR 1 of the simplified HAI single-run-task stack:

- [#19047](https://github.com/openai/codex/pull/19047) Agent Identity
assertion and task-registration primitives, including the shared
run-task helper used by existing Agent Identity JWT auth.
- [#19049](https://github.com/openai/codex/pull/19049)
Disabled-by-default ChatGPT auth opt-in that provisions/reuses persisted
Agent Identity runtime auth and its single run task.
- [#19051](https://github.com/openai/codex/pull/19051) Run-scoped

inference and compaction requests.

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

## Summary

The simplified POC shape is one backend-owned task per Agent Identity
run. This PR makes the first layer match that final shape directly
instead of introducing task targets, caller-owned external task refs, or
intermediate wrappers that later PRs would need to undo.

What changed:

- keeps the `AgentAssertion` wire payload as `agent_runtime_id`,
`task_id`, `timestamp`, and `signature`
- exposes `register_agent_task` as the single task-registration helper
for both existing Agent Identity JWT auth and the ChatGPT-registration
path added later in the stack
- makes task registration send only the signed registration timestamp;
the backend owns the returned opaque task id
- removes the unused target/task-kind/external-task-ref surfaces from
`codex-agent-identity`
- keeps Agent Identity JWT JWKS lookup separate from agent/task
registration URL derivation
- updates Agent Identity JWT auth to register one run task during auth
construction and share that task across cloned auth handles

This PR intentionally does not enable ChatGPT-derived Agent Identity.
That opt-in and config gate are added in the next PR.

## Why

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.

AbhinavandGitHub d007b0852a Preserve hook trust bypass in codex exec threads (#26434)
Addresses #26383 and #26452

## Summary

`codex exec --dangerously-bypass-hook-trust` printed the bypass warning,
but valid untrusted hooks still did not run.

Exec applied the flag to its initial config, then lost it when
app-server reloaded config for the new or resumed thread.

## Fix

Forward `bypass_hook_trust: true` through the existing thread request
config override for both start and resume.

The override is omitted when the flag is not enabled, preserving normal
trust behavior.

## Testing

Added:

- A test confirming start and resume preserve the override.
- An end-to-end exec test confirming a `SessionStart` hook runs and
creates a marker file.

Brent TrautandGitHub dfd03ea01b feat(app-server): filter threads by parent (#26662)
## Why

Clients that display or coordinate spawned subagents need an
authoritative snapshot of a thread's immediate spawned children when
they connect to app-server or recover after missing live events.
`thread/list` cannot query by parent, so clients must otherwise scan
unrelated threads or reconstruct relationships from rollout history and
transient events.

The direct spawn relationship already exists in persisted
`thread_spawn_edges` state. Review and Guardian threads do not
participate in that lifecycle and are intentionally outside this
filter's scope.

## What changed

This adds an experimental `parentThreadId` filter to `thread/list`.
Parent-filtered requests return direct spawned children from persisted
state while preserving the existing response shape, explicit filters,
sorting, and timestamp-only cursor behavior. The lookup does not read
rollout transcripts or recursively return descendants.

Supersedes #25112 with the narrower `thread/list` filter approach.

## How it works

1. An experimental client passes a valid thread ID as `parentThreadId`.
2. App-server routes the list through the existing thread-store and
state-database boundaries.
3. SQLite selects threads whose IDs have a direct persisted spawn edge
from that parent.
4. Omitted provider and source filters include all values; explicit
filters keep ordinary `thread/list` semantics.
5. Grandchildren, Review threads, and Guardian threads are excluded.

## Verification

State (144 tests), rollout (69 tests), and focused app-server
thread-list (31 tests) suites passed. Scoped Clippy checks and
repository formatting also passed. Coverage includes direct spawned
children, omitted grandchildren, pagination, malformed IDs, mixed source
kinds, explicit filters, and operation without rollout files.

Celia ChenandGitHub 56c97e3b5c feat: use encrypted local secrets for CLI auth (#27539)
## Why

Windows Credential Manager limits generic credential blobs to 2,560
bytes. Large serialized ChatGPT auth payloads can exceed that limit, so
keyring-mode CLI auth needs a backend that keeps only the encryption key
in the OS keyring and stores the payload in Codex's encrypted
local-secrets file.

This is the third PR in the encrypted-auth stack:

1. #27504 — feature and config selection
2. #27535 — auth-specific local-secrets namespaces
3. This PR — CLI auth implementation and activation
4. MCP OAuth implementation and activation

## What Changed

- Added encrypted CLI-auth storage using the `CliAuth` secrets
namespace.
- Preserved direct keyring storage for platforms/configurations where it
remains selected.
- Selected the backend consistently for login, logout, refresh,
device-code login, auth loading, and login restrictions.
- Threaded resolved bootstrap/full config through CLI, exec, TUI,
app-server account handling, cloud config, and cloud tasks.
- Removed stale `auth.json` fallback data after successful encrypted
saves and removed encrypted, direct-keyring, and fallback data during
logout.
- Added storage and integration coverage for both direct and encrypted
keyring modes.

MCP OAuth persistence is intentionally left to the next PR.

## Validation

Adam Perry @ OpenAIandGitHub 7fbbc9f033 [codex] Surface runtime warnings in codex exec (#27415)
## Why

`codex exec` drops thread-scoped warning notifications. Warnings
discovered while a thread starts, including unreadable or invalid UTF-8
project `AGENTS.md` files, therefore become silent.

## What changed

- Process global and primary-thread warning notifications while
continuing to ignore warnings from unrelated threads.
- Render runtime warnings in human output and expose them through the
existing non-fatal error item in JSONL output.
- Add focused routing, rendering, and malformed project-instruction
coverage.

marksteinbrick-oaiandGitHub a71e040df5 [codex-analytics] add extensible feature thread sources (#27063)
## Why
- `ThreadSource` currently defines a closed set of core-owned values
- Product features also create threads for background or scheduled work
- Adding every product-specific value to the core enum would require
repeated `codex-rs` protocol changes
- Feature-backed values let product callers provide precise attribution
while preserving the existing core classifications

## What Changed
- Adds `ThreadSource::Feature(String)` for app-owned thread source
values
- Represents all app-server v2 thread sources as scalar strings, so a
feature source is supplied as `"automation"`
- Persists and emits the feature's plain string label, so `"automation"`
produces `thread_source="automation"` in analytics
- Keeps `user`, `subagent`, and `memory_consolidation` as explicit
core-owned values and regenerates the app-server schemas and TypeScript
bindings

## Verification
- `just write-app-server-schema`
- `cargo check --workspace`
- `just test -p codex-protocol

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

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.

joeflorencio-openaiandGitHub d45cd26248 Switch runtime to cloud config bundle (#24622)
## Summary

- Adapts the moved `codex-cloud-config` crate from the legacy cloud
requirements endpoint to the new config bundle endpoint.
- Switches runtime consumers from `CloudRequirementsLoader` to
`CloudConfigBundleLoader` so one shared bundle supplies cloud-delivered
config and requirements.
- Removes the legacy cloud requirements domain loader path.

## Details

This intentionally keeps `codex-cloud-config` monolithic for review
lineage: the previous PR establishes the crate move, and this PR shows
the behavior change against that moved implementation. A follow-up PR
splits the module back into focused files.

The new bundle path preserves the important cloud requirements loader
semantics where intended: account-scoped signed cache, 30 minute TTL, 5
minute refresh cadence, retry/backoff, auth recovery, and fail-closed
startup loading. The cached payload changes from a single requirements
TOML string to the backend-delivered bundle, and validation rejects
malformed config or requirements fragments before cache write/use.

joeflorencio-openaiandGitHub 0b3a6f7185 Move cloud requirements crate to cloud config (#24621)
## Summary

- Moves the existing `codex-cloud-requirements` crate to
`codex-cloud-config`.
- Updates workspace dependencies and imports to the new crate name.
- Intentionally keeps runtime behavior unchanged: this still fetches the
legacy cloud requirements endpoint.

## Details

This PR exists to make the lineage obvious before the bundle migration.
GitHub should show the old `codex-rs/cloud-requirements/src/lib.rs`
implementation as moved to `codex-rs/cloud-config/src/lib.rs`, rather
than as unrelated new code.

The follow-up PR adapts this moved crate to the new config bundle API
and switches runtime consumers over.

Won ParkandGitHub 13edafb6ed Preserve auto-review approval policy in codex exec (#23763)
## Why

`codex exec` was forcing headless runs to `approval_policy = "never"`
even when the resolved reviewer was `auto_review`. That prevented
unattended exec workflows from reaching the reviewed MCP write path they
were configured to use.

## What changed

- Keep the existing headless `never` default for ordinary exec runs.
- Re-resolve exec config without that synthetic override when the final
reviewer resolves to `AutoReview`, so configured or requirements-driven
approval policy is preserved.
- Add regression coverage for:
  - `auto_review` plus `on-request` from user config
- requirements-driven `AutoReview`, asserting exec’s final approval
policy matches the no-override control config exactly

## Validation

- `just fmt`
- `cargo test -p codex-exec`

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.

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.
- Regenerates app-server schema fixtures.

## Validation

- `just fmt`
- `just write-app-server-schema`
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-protocol`
- `just fix -p codex-app-server-protocol`

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.

Michael BolinandGitHub c7bcb90f9b package: include zsh fork in Codex package (#23756)
## Why

The package layout gives Codex a stable place for runtime helpers that
should travel with the entrypoint. `shell_zsh_fork` still required users
to configure `zsh_path` manually, even though we already publish
prebuilt zsh fork artifacts.

This PR builds on #24129 and uses the shared DotSlash artifact fetcher
to include the zsh fork in Codex packages when a matching target
artifact exists. Packaged Codex builds can then discover the bundled
fork automatically; the user/profile `zsh_path` override is removed so
the feature uses the package-managed artifact instead of a legacy path
knob.

## What Changed

- Added `scripts/codex_package/codex-zsh`, a checked-in DotSlash
manifest for the current macOS arm64 and Linux zsh fork artifacts.
- Taught `scripts/build_codex_package.py` to fetch the matching zsh fork
artifact and install it at `codex-resources/zsh/bin/zsh` when available
for the selected target.
- Added package layout validation for the optional bundled zsh resource.
- Added `InstallContext::bundled_zsh_path()` and
`InstallContext::bundled_zsh_bin_dir()` for package-layout resource
discovery.
- Threaded the packaged zsh path through config loading as the runtime
`zsh_path` for packaged installs, and removed the config/profile/CLI
override path.
- Kept the packaged default zsh override typed as `AbsolutePathBuf`
until the existing runtime `Config::zsh_path` boundary.
- Updated app-server zsh-fork integration tests to spawn
`codex-app-server` from a temporary package layout with
`codex-resources/zsh/bin/zsh`, matching the new packaged discovery path
instead of setting `zsh_path` in config.
- Switched package executable copying from metadata-preserving `copy2()`
to `copyfile()` plus explicit executable bits, which avoids macOS
file-flag failures when local smoke tests use system binaries as inputs.

## Testing

To verify that the `zsh` executable from the Codex package is picked up
correctly, first I ran:

```shell
./scripts/build_codex_package.py
```

which created:

```
/private/var/folders/vw/x2knqmks50sfhfpy27nftl900000gp/T/codex-package-pms94kdp/
```

so then I ran:

```
/private/var/folders/vw/x2knqmks50sfhfpy27nftl900000gp/T/codex-package-pms94kdp/bin/codex exec --enable shell_zsh_fork 'run `echo $0`'
```

which reported the following, as expected:

```
/private/var/folders/vw/x2knqmks50sfhfpy27nftl900000gp/T/codex-package-pms94kdp/codex-resources/zsh/bin/zsh
```

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.

jif-oaiandGitHub fd72e99384 config: remove legacy profile v1 resolution (#24051)
## Why

[#23883](https://github.com/openai/codex/pull/23883) moved user-facing
`--profile` selection onto profile v2, and
[#23886](https://github.com/openai/codex/pull/23886) removed the old CLI
`config_profile` override path. Core still had a second legacy path:
`profile = "..."` could select `[profiles.*]` values while runtime
config was built. Keeping that resolver alive preserves the old
precedence model and profile-carrying surfaces even though profile
selection now points at `$CODEX_HOME/<name>.config.toml`.

## What

- Reject legacy top-level `profile = "..."` config while loading runtime
config, with an error that points callers at `--profile <name>` and
`<name>.config.toml` in the [core load
path](https://github.com/openai/codex/blob/3d923366eca10a29143623124c6c6e538f058269/codex-rs/core/src/config/mod.rs#L2524-L2531).
- Remove the remaining profile-v1 merge points from runtime config
resolution, including features, permissions, model/provider selection,
web search, Windows sandbox settings, TUI settings, role reloads, and
OSS provider lookup.
- Drop the leftover profile override surface from
[`ConfigOverrides`](https://github.com/openai/codex/blob/3d923366eca10a29143623124c6c6e538f058269/codex-rs/core/src/config/mod.rs#L2118-L2148)
and from the MCP server `codex` tool schema.
- Prune profile-precedence tests that only exercised the removed
resolver and replace them with rejection coverage for the legacy
selector.

## Testing

- Not run in this metadata pass.
- Added
[`legacy_profile_selection_is_rejected`](https://github.com/openai/codex/blob/3d923366eca10a29143623124c6c6e538f058269/codex-rs/core/src/config/config_tests.rs#L7942-L7965)
coverage for the new runtime guard.

jif-oaiandGitHub e0e304b123 cli: remove legacy profile v1 plumbing (#23886)
## Why

[#23883](https://github.com/openai/codex/pull/23883) moved the
user-facing `--profile` flag onto profile v2. The shared CLI option
layer still carried the old `config_profile` slot and several CLI
entrypoints still copied that value into legacy config overrides.
Leaving that path around makes the CLI surface look like it still
selects legacy `[profiles.*]` state even though `--profile` now means
`$CODEX_HOME/<name>.config.toml`.

## What

- Remove the legacy `config_profile` field and merge/copy path from
[`SharedCliOptions`](https://github.com/openai/codex/blob/95baaf72920c8db22097df8d15a0bb76c84528b6/codex-rs/utils/cli/src/shared_options.rs#L8-L177).
- Stop forwarding profile-v1 overrides from CLI, exec, TUI, doctor,
debug, feature, and exec-server paths; runtime profile selection remains
on `config_profile_v2` through
[`loader_overrides_for_profile`](https://github.com/openai/codex/blob/95baaf72920c8db22097df8d15a0bb76c84528b6/codex-rs/cli/src/main.rs#L1606-L1619).
- Resolve local OSS provider selection from the base config in exec and
TUI now that the legacy profile argument is gone.

## Testing

- Not run (cleanup-only follow-up to #23883).

Matthew ZengandGitHub 0a4179bb19 [codex] Add plugin id to MCP tool call items (#23737)
Add owning plugin id to MCP tool call items so we can better filter them
at plugin level.

## Summary
- add optional `plugin_id` to MCP tool-call items and legacy begin/end
events
- propagate plugin metadata into emitted core items and app-server v2
`ThreadItem::McpToolCall`
- preserve plugin ids through app-server replay/redaction paths and
regenerate v2 schema fixtures

## Testing
- `just write-app-server-schema`
- `just fmt`
- `just fix -p codex-core`
- `cargo test -p codex-protocol -p codex-app-server-protocol`
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-core mcp_tool_call_item_includes_plugin_id --lib`
- `cargo check -p codex-tui --tests`
- `cargo check -p codex-app-server --tests`
- `git diff --check`

## Notes
- `just fix -p codex-core` completed with two non-fatal
`too_many_arguments` warnings on the touched MCP notification helpers.
- A broader `cargo test -p codex-core` run passed core unit tests, then
hit shell/sandbox/snapshot failures in the integration target.
- A broader app-server downstream run hit the existing
`in_process::tests::in_process_start_clamps_zero_channel_capacity` stack
overflow; `cargo test -p codex-exec` also hit the existing sandbox
expectation mismatch in
`thread_lifecycle_params_include_legacy_sandbox_when_no_active_profile`.

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`

marksteinbrick-oaiandGitHub 5696167fe8 [codex-analytics] preserve user thread source for exec threads (#23376)
## Why
- Follows #20949.
- The above moved `thread_source` attribution from the reducer to
explicit caller provided metadata
- The `codex exec` path still omitted this metadata, leaving
exec-created threads without `thread_source`


## What Changed
- Ensures exec threads are marked as user created (`thread_source =
"user"`)
- Preserves thread-source metadata in exec’s startup session event


## Verification
- Updated unit tests to validate exec `thread_source` propagation.
- `cargo +1.93.0 test -p codex-exec --manifest-path codex-rs/Cargo.toml`
- `cargo +1.93.1 build -p codex-cli --manifest-path codex-rs/Cargo.toml`
- Validated locally with a freshly built `codex exec` run:
  - Startup logs showed `thread_source: Some(User)`.
  - Rollout metadata recorded `"thread_source":"user"`.

Eric TrautandGitHub af6ffb6ebb Support --output-schema for exec resume (#23123)
## Why

`codex exec resume` should have the same structured-output support as
top-level `codex exec`. Without `--output-schema`, multi-turn automation
has to choose between resumed session context and schema-validated JSON
output.

Fixes #22998.

## What changed

- Marked `--output-schema` as a global `codex exec` flag so it can be
passed after `resume`.
- Reused the existing output schema plumbing so resumed turns attach the
schema to the final response request while preserving session context.

Curtis 'Fjord' HawthorneandGitHub 8543e39885 Preserve image detail in app-server inputs (#20693)
## Summary

- Add optional image detail to user image inputs across core, app-server
v2, thread history/event mapping, and the generated app-server
schemas/types.
- Preserve requested detail when serializing Responses image inputs:
omitted detail stays on the existing `high` default, while explicit
`original` keeps local images on the original-resolution path.
- Support `high`/`original` consistently for tool image outputs,
including MCP `codex/imageDetail`, code-mode image helpers, and
`view_image`.

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 8adb6032cc tui/exec: show effective workspace roots in summaries (#22612)
## Why

This PR builds on [#22611](https://github.com/openai/codex/pull/22611).

After `runtimeWorkspaceRoots` moved onto thread state, the user-facing
summaries were still inconsistent about which roots they showed. In
particular, `/status` and the exec startup summary could under-report
extra workspace roots from `--add-dir` or from profile-defined
`workspace_roots`, which made the new model look incorrect even when the
permissions themselves were right.

## What Changed

- switched the TUI status surfaces to summarize against
`Config::effective_workspace_roots()`
- updated the exec human-output summary to render from the effective
permission profile instead of the raw constrained profile
- added focused regressions for both the TUI and exec code paths so
extra workspace roots stay visible in user-facing summaries

## Verification

Targeted coverage for this follow-up lives in:
- `codex-rs/tui/src/status/tests.rs`
- `codex-rs/exec/src/event_processor_with_human_output_tests.rs`

The added regressions verify that:
- status output includes profile-defined workspace roots in the
effective permissions summary
- exec startup output includes runtime workspace roots instead of
collapsing back to `cwd` only

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 3c6d727810 permissions: resolve profile identity with constraints (#22683)
## Why

This PR is the invariant-cleanup layer that follows the workspace-roots
base merged in [#22610](https://github.com/openai/codex/pull/22610).

#22610 adds `[permissions.<id>.workspace_roots]` and keeps runtime
workspace roots separate from the raw permission profile, but its
in-memory representation is intentionally transitional: `Permissions`
still carries the selected profile identity next to a constrained
`PermissionProfile`. That makes APIs such as
`set_constrained_permission_profile_with_active_profile()` fragile
because the id and value only mean the right thing when every caller
keeps them in sync.

This PR introduces a single resolved profile state so profile identity,
`extends`, the profile value, and profile-declared workspace roots
travel together. The next PR,
[#22611](https://github.com/openai/codex/pull/22611), builds on this by
changing the app-server turn API to select permission profiles by id
plus runtime workspace roots.

## Stack Context

- #22610, now merged: adds profile-declared `workspace_roots`, runtime
workspace roots, and `:workspace_roots` materialization.
- This PR: replaces the parallel active-profile/profile-value fields
with `PermissionProfileState`.
- #22611: switches app-server turn updates toward profile ids plus
runtime workspace roots.
- #22612: updates TUI/exec summaries to show the effective workspace
roots.

Keeping this separate from #22611 is deliberate: reviewers can validate
the internal state invariant before reviewing the app-server protocol
migration.

## What Changed

- Added `ResolvedPermissionProfile::{Legacy, BuiltIn, Named}` and
`PermissionProfileState`.
- Typed built-in profile ids with `BuiltInPermissionProfileId`.
- Moved selected profile identity and profile-declared workspace roots
into the resolved state.
- Replaced `Permissions` parallel profile fields with one
`permission_profile_state`.
- Removed `set_constrained_permission_profile_with_active_profile()`
from session sync paths.
- Kept trusted session replay/`SessionConfigured` compatibility through
explicit session snapshot helpers.
- Updated session configuration, MCP initialization, app-server, exec,
TUI, and guardian call sites to consume `&PermissionProfile` directly.

## Review Guide

Start with `codex-rs/core/src/config/resolved_permission_profile.rs`; it
is the new invariant boundary. Then review
`codex-rs/core/src/config/mod.rs` to see how config loading records
active profile identity and profile workspace roots. The remaining
call-site changes are mostly mechanical fallout from
`Permissions::permission_profile()` returning `&PermissionProfile`
instead of `&Constrained<PermissionProfile>`.

## Verification

The existing config/session coverage now constructs and asserts through
`PermissionProfileState`. The workspace-root config test also asserts
that profile-declared roots are preserved in the resolved state, which
is the behavior #22611 relies on when runtime roots become mutable
through the app-server API.

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 e8969d940d test: isolate exec review policy config test (#22512)
## Why


`thread_start_params_include_review_policy_when_review_policy_is_manual_only`
builds a `Config` with a temporary `CODEX_HOME`, but
`ConfigBuilder::default()` can still load host-managed configuration. On
local macOS machines with enterprise-managed Codex config, that host
state can leak into the test and change the resulting config, even
though CI does not have the same managed config source.

This makes the test environment-dependent: it can pass in CI while
failing locally for developers who have managed configuration installed.

## What Changed

- Updated `codex-rs/exec/src/lib_tests.rs` so the test calls
`LoaderOverrides::without_managed_config_for_tests()` through
`ConfigBuilder::loader_overrides(...)`.
- Left the rest of the test setup intact, including the temporary
`CODEX_HOME`, temporary cwd, and explicit `approvals_reviewer` harness
override.

deedf3b2c4 feat: add layered --profile-v2 config files (#17141)
## Why

`--profile-v2 <name>` gives launchers and runtime entry points a named
profile config without making each profile duplicate the base user
config. The base `$CODEX_HOME/config.toml` still loads first, then
`$CODEX_HOME/<name>.config.toml` layers above it and becomes the active
writable user config for that session.

That keeps shared defaults, plugin/MCP setup, and managed/user
constraints in one place while letting a named profile override only the
pieces that need to differ.

## What Changed

- Added the shared `--profile-v2 <name>` runtime option with validated
plain names, now represented by `ProfileV2Name`.
- Extended config layer state so the base user config and selected
profile config are both `User` layers; APIs expose the active user layer
and merged effective user config.
- Threaded profile selection through runtime entry points: `codex`,
`codex exec`, `codex review`, `codex resume`, `codex fork`, and `codex
debug prompt-input`.
- Made user-facing config writes go to the selected profile file when
active, including TUI/settings persistence, app-server config writes,
and MCP/app tool approval persistence.
- Made plugin, marketplace, MCP, hooks, and config reload paths read
from the merged user config so base and profile layers both participate.
- Updated app-server config layer schemas to mark profile-backed user
layers.

## Limits

`--profile-v2` is still rejected for config-management subcommands such
as feature, MCP, and marketplace edits. Those paths remain tied to the
base `config.toml` until they have explicit profile-selection semantics.

Some adjacent background writes may still update base or global state
rather than the selected profile:

- marketplace auto-upgrade metadata
- automatic MCP dependency installs from skills
- remote plugin sync or uninstall config edits
- personality migration marker/default writes

## Verification

Added targeted coverage for profile name validation, layer
ordering/merging, selected-profile writes, app-server config writes,
session hot reload, plugin config merging, hooks/config fixture updates,
and MCP/app approval persistence.

Michael BolinandGitHub 889ee018e7 config: add strict config parsing (#20559)
## Why

Codex intentionally ignores unknown `config.toml` fields by default so
older and newer config files keep working across versions. That leniency
also makes typo detection hard because misspelled or misplaced keys
disappear silently.

This change adds an opt-in strict config mode so users and tooling can
fail fast on unrecognized config fields without changing the default
permissive behavior.

This feature is possible because `serde_ignored` exposes the exact
signal Codex needs: it lets Codex run ordinary Serde deserialization
while recording fields Serde would otherwise ignore. That avoids
requiring `#[serde(deny_unknown_fields)]` across every config type and
keeps strict validation opt-in around the existing config model.

## What Changed

### Added strict config validation

- Added `serde_ignored`-based validation for `ConfigToml` in
`codex-rs/config/src/strict_config.rs`.
- Combined `serde_ignored` with `serde_path_to_error` so strict mode
preserves typed config error paths while also collecting fields Serde
would otherwise ignore.
- Added strict-mode validation for unknown `[features]` keys, including
keys that would otherwise be accepted by `FeaturesToml`'s flattened
boolean map.
- Kept typed config errors ahead of ignored-field reporting, so
malformed known fields are reported before unknown-field diagnostics.
- Added source-range diagnostics for top-level and nested unknown config
fields, including non-file managed preference source names.

### Kept parsing single-pass per source

- Reworked file and managed-config loading so strict validation reuses
the already parsed `TomlValue` for that source.
- For actual config files and managed config strings, the loader now
reads once, parses once, and validates that same parsed value instead of
deserializing multiple times.
- Validated `-c` / `--config` override layers with the same
base-directory context used for normal relative-path resolution, so
unknown override keys are still reported when another override contains
a relative path.

### Scoped `--strict-config` to config-heavy entry points

- Added support for `--strict-config` on the main config-loading entry
points where it is most useful:
  - `codex`
  - `codex resume`
  - `codex fork`
  - `codex exec`
  - `codex review`
  - `codex mcp-server`
  - `codex app-server` when running the server itself
  - the standalone `codex-app-server` binary
  - the standalone `codex-exec` binary
- Commands outside that set now reject `--strict-config` early with
targeted errors instead of accepting it everywhere through shared CLI
plumbing.
- `codex app-server` subcommands such as `proxy`, `daemon`, and
`generate-*` are intentionally excluded from the first rollout.
- When app-server strict mode sees invalid config, app-server exits with
the config error instead of logging a warning and continuing with
defaults.
- Introduced a dedicated `ReviewCommand` wrapper in `codex-rs/cli`
instead of extending shared `ReviewArgs`, so `--strict-config` stays on
the outer config-loading command surface and does not become part of the
reusable review payload used by `codex exec review`.

### Coverage

- Added tests for top-level and nested unknown config fields, unknown
`[features]` keys, typed-error precedence, source-location reporting,
and non-file managed preference source names.
- Added CLI coverage showing invalid `--enable`, invalid `--disable`,
and unknown `-c` overrides still error when `--strict-config` is
present, including compound-looking feature names such as
`multi_agent_v2.subagent_usage_hint_text`.
- Added integration coverage showing both `codex app-server
--strict-config` and standalone `codex-app-server --strict-config` exit
with an error for unknown config fields instead of starting with
fallback defaults.
- Added coverage showing unsupported command surfaces reject
`--strict-config` with explicit errors.

## Example Usage

Run Codex with strict config validation enabled:

```shell
codex --strict-config
```

Strict config mode is also available on the supported config-heavy
subcommands:

```shell
codex --strict-config exec "explain this repository"
codex review --strict-config --uncommitted
codex mcp-server --strict-config
codex app-server --strict-config --listen off
codex-app-server --strict-config --listen off
```

For example, if `~/.codex/config.toml` contains a typo in a key name:

```toml
model = "gpt-5"
approval_polic = "on-request"
```

then `codex --strict-config` reports the misspelled key instead of
silently ignoring it. The path is shortened to `~` here for readability:

```text
$ codex --strict-config
Error loading config.toml:
~/.codex/config.toml:2:1: unknown configuration field `approval_polic`
  |
2 | approval_polic = "on-request"
  | ^^^^^^^^^^^^^^
```

Without `--strict-config`, Codex keeps the existing permissive behavior
and ignores the unknown key.

Strict config mode also validates ad-hoc `-c` / `--config` overrides:

```text
$ codex --strict-config -c foo=bar
Error: unknown configuration field `foo` in -c/--config override

$ codex --strict-config -c features.foo=true
Error: unknown configuration field `features.foo` in -c/--config override
```

Invalid feature toggles are rejected too, including values that look
like nested config paths:

```text
$ codex --strict-config --enable does_not_exist
Error: Unknown feature flag: does_not_exist

$ codex --strict-config --disable does_not_exist
Error: Unknown feature flag: does_not_exist

$ codex --strict-config --enable multi_agent_v2.subagent_usage_hint_text
Error: Unknown feature flag: multi_agent_v2.subagent_usage_hint_text
```

Unsupported commands reject the flag explicitly:

```text
$ codex --strict-config cloud list
Error: `--strict-config` is not supported for `codex cloud`
```

## Verification

The `codex-cli` `strict_config` tests cover invalid `--enable`, invalid
`--disable`, the compound `multi_agent_v2.subagent_usage_hint_text`
case, unknown `-c` overrides, app-server strict startup failure through
`codex app-server`, and rejection for unsupported commands such as
`codex cloud`, `codex mcp`, `codex remote-control`, and `codex
app-server proxy`.

The config and config-loader tests cover unknown top-level fields,
unknown nested fields, unknown `[features]` keys, source-location
reporting, non-file managed config sources, and `-c` validation for keys
such as `features.foo`.

The app-server test suite covers standalone `codex-app-server
--strict-config` startup failure for an unknown config field.

## Documentation

The Codex CLI docs on developers.openai.com/codex should mention
`--strict-config` as an opt-in validation mode for supported
config-heavy entry points once this ships.
