## Why
When remote control hits an auth failure such as a revoked or reused
refresh token, the websocket loop falls into reconnect backoff. If the
user fixes auth while that loop is sleeping, remote control can stay
offline until the old retry timer expires because nothing wakes the loop
or resets its exhausted auth recovery state.
## What Changed
Added an auth-change watch on `AuthManager` for refresh-relevant cached
auth updates.
The remote-control websocket loop now subscribes to that signal, resets
`UnauthorizedRecovery` and reconnect backoff when auth changes, and
retries immediately instead of waiting for the previous delay.
Updated the remote-control transport test to verify that reloading auth
with the now-available account id wakes enrollment before the prior
retry delay.
## Verification
`cargo test -p codex-app-server-transport
remote_control_waits_for_account_id_before_enrolling`
## Summary
- make rollout content search prefilter rollout files case-insensitively
- keep the no-ripgrep fallback scan and visible snippet matcher aligned
with that behavior
- cover a lowercase `thread/search` query matching mixed-case
conversation content
## Why
The rollout-backed `thread/search` path used exact string matching in
both its `rg` prefilter and semantic snippet generation. A content
result could be missed solely because the query casing did not match the
stored conversation text.
## Validation
- `just fmt`
- `cargo test -p codex-app-server thread_search_returns_content_matches`
- `cargo test -p codex-rollout`
- `just bazel-lock-update`
- `just bazel-lock-check`
- `cargo build -p codex-cli`
- launched a local Electron dev instance with the rebuilt CLI binary
# Why
This is a follow-up stacked on top of the `plugin_hooks` default-on
change. Once we are comfortable making plugin hooks part of the normal
plugin behavior, the separate feature flag stops buying us much and
leaves extra branching/cache state behind.
# What
- remove the `PluginHooks` feature and generated config-schema entries
- make plugin hook loading/listing follow plugin enablement directly
- drop plugin-manager cache/state that only existed to distinguish
hook-flag toggles
- remove tests and fixtures that modeled `plugin_hooks = true/false`
## Summary
- add experimental `thread/search` for local rollout-backed thread
search using `rg` over JSONL rollouts
- return search-specific result rows with optional previews instead of
storing preview data on `StoredThread` or ordinary `Thread` responses
- keep `thread/list` separate from full-content search and document the
new app-server surface
## Testing
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-app-server
thread_search_returns_content_and_title_matches -- --nocapture`
## Summary
- route each configured MCP server through an explicit per-server
`environment_id` instead of a manager-wide remote toggle
- default omitted `environment_id` to `local`, resolve named ids through
`EnvironmentManager`, and fail only the affected MCP server when an
explicit id is unknown
- keep local stdio on the existing local launcher path for now, while
named-environment stdio uses the selected environment backend and
requires an absolute `cwd`
- allow local HTTP MCP servers to keep using the ambient HTTP client
when no local `Environment` is configured; named-environment HTTP MCPs
use that environment's HTTP client
## Validation
- devbox Bazel build: `bazel build --bes_backend= --bes_results_url=
//codex-rs/cli:codex //codex-rs/rmcp-client:test_stdio_server
//codex-rs/rmcp-client:test_streamable_http_server`
- devbox app-server config matrix with real `config.toml` /
`environments.toml` files covering omitted local, explicit local,
omitted local under remote default, explicit remote stdio, local HTTP
without local env, explicit remote HTTP, local stdio without local env,
unknown explicit env, and remote stdio without `cwd`
## Why
Cloud-managed `requirements.toml` should be able to define the managed
permission profiles a client may select and constrain that selectable
set without requiring local user config to recreate the profile catalog.
This keeps requirements focused on restrictions. The selected default
remains a config or session choice, while requirements contribute the
managed profile bodies and `allowed_permissions` allowlist that the
config-loading boundary validates before a resolved runtime
`PermissionProfile` is installed.
## What changed
- Add `requirements.toml` support for a managed permission-profile
catalog plus its allowlist:
```toml
allowed_permissions = ["review", "build"]
[permissions.review]
extends = ":read-only"
[permissions.build]
extends = ":workspace"
```
- Merge requirements-defined profile bodies into the effective
permission catalog and reject profile ids that collide with
config-defined profiles.
- Validate that every `allowed_permissions` entry resolves to a built-in
or catalog profile before selection uses it.
- Preserve allowed configured named-profile selections. When a
configured named profile is disallowed, fall back to the first allowed
requirements profile with a startup warning.
- Keep built-in selections and the stock trust-based `:read-only` /
`:workspace` fallback path intact when no permission profile is
explicitly selected.
- Centralize the managed catalog and allowlist selection path in
`EffectivePermissionSelection` so the requirements boundary is visible
in config loading.
- Surface `allowedPermissions` through `configRequirements/read`, and
update the generated app-server schema fixtures plus the app-server
README.
## Validation
- `cargo test -p codex-config`
- `cargo test -p codex-core system_requirements_`
- `cargo test -p codex-core system_allowed_permissions_`
- `cargo test -p codex-app-server-protocol`
- `just write-app-server-schema`
## Related work
- Uses merged permission-profile inheritance support from #22270 and
#23705.
- Kept separate from the in-flight permission profile listing API in
#23412.
## Why
If a user configures `approval_policy = "never"` with `sandbox_mode =
"danger-full-access"`, managed requirements can reject full access and
force the existing permission fallback to read-only. That leaves Codex
in a dead-end session: writes are blocked by the sandbox, while
approvals are disabled so the session cannot ask to proceed.
This PR rejects that constrained configuration during startup instead of
letting the TUI enter a read-only session that cannot make progress. The
rejection is attached to the requirement-constrained permission path in
[`Config`](39f0abc0a7/codex-rs/core/src/config/mod.rs (L3301-L3318)).
## What changed
- Reject the `danger-full-access` to read-only managed-requirements
fallback when the effective approval policy is `never`.
- Explain in the startup config error why the fallback is invalid and
how to fix it.
- Add a regression test for the managed requirements path.
## Stack
1. Parent PR: #18868 adds MITM hook config and model only.
2. Parent PR: #20659 wires hook enforcement into the proxy request path.
3. This PR changes the user facing PermissionProfile TOML shape.
## Why
1. The broader goal is to make MITM clamping usable from the same
permission profile that already controls network behavior.
2. This PR is the config UX layer for the stack. It moves MITM policy
into `[permissions.<profile>.network.mitm]` instead of exposing the flat
runtime shape to users.
3. The named hook and action tables belong here because users need
reusable policy blocks that are easy to review, while the proxy runtime
only needs a flat hook list.
4. This PR validates action refs during config parsing so mistakes in
the user facing policy fail before a proxy session starts.
5. Keeping the lowering here lets the proxy keep its simpler runtime
model and lets PermissionProfile remain the single source of network
permission policy.
## Summary
1. Keep MITM policy inside `[permissions.<profile>.network.mitm]` so the
selected PermissionProfile owns network proxy policy.
2. Use named MITM hooks under
`[permissions.<profile>.network.mitm.hooks.<name>]`.
3. Put host, methods, path prefixes, query, headers, body, and action
refs on the hook table.
4. Define reusable action blocks under
`[permissions.<profile>.network.mitm.actions.<name>]`.
5. Represent action blocks with `NetworkMitmActionToml`, then lower them
into the proxy runtime action config.
6. Reject unknown refs, empty refs, and empty action blocks during
config parsing.
7. Keep the runtime hook model unchanged by lowering config into the
existing proxy hook list.
8. Preserve the #20659 activation fix for nested MITM policy.
## Example
```toml
[permissions.workspace.network.mitm]
enabled = true
[permissions.workspace.network.mitm.hooks.github_write]
host = "api.github.com"
methods = ["POST", "PUT"]
path_prefixes = ["/repos/openai/"]
action = ["strip_auth"]
[permissions.workspace.network.mitm.actions.strip_auth]
strip_request_headers = ["authorization"]
```
## Validation
1. Regenerated the config schema.
2. Ran the core MITM config parsing and validation tests.
3. Ran the core PermissionProfile MITM proxy activation tests.
4. Ran the core config schema fixture test.
5. Ran the network proxy MITM policy tests.
6. Ran the scoped Clippy fixer for the network proxy crate.
7. Ran the scoped Clippy fixer for the core crate.

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`.
## 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.
## Validation
- `CARGO_INCREMENTAL=0 cargo build -p codex-cli`
- `CARGO_INCREMENTAL=0 cargo test -p codex-app-server model_list`
- `cargo test -p codex-tui service_tier`
- `cargo test -p codex-protocol service_tier_for_request`
- `cargo test -p codex-core get_service_tier`
- `RUST_MIN_STACK=8388608 CARGO_INCREMENTAL=0 cargo test -p codex-core
service_tier`
## Why
The `goals` feature is ready to be available without requiring users to
opt into experimental features. Keeping it behind the beta flag leaves
persisted thread goals and automatic goal continuation disabled by
default.
This PR also marks the goal-related app server APIs and events as no
longer experimental.
## What changed
- Mark `goals` as `Stage::Stable`.
- Enable `goals` by default in `codex-rs/features/src/lib.rs`.

`SubagentStop` runs when a thread-spawned subagent turn is about to
finish. Thread-spawned subagents use `SubagentStop` instead of the
normal root-agent `Stop` hook.
Configured handlers match on `agent_type`. Hook input includes the
normal stop fields plus:
- `agent_id`: the child thread id.
- `agent_type`: the resolved subagent type.
- `agent_transcript_path`: the child subagent transcript path.
- `transcript_path`: the parent thread transcript path.
- `last_assistant_message`: the final assistant message from the child
turn, when available.
- `stop_hook_active`: `true` when the child is already continuing
because an earlier stop-like hook blocked completion.
`SubagentStop` shares the same completion-control semantics as `Stop`,
scoped to the child turn:
- No decision allows the child turn to finish.
- `decision: "block"` with a non-empty `reason` records that reason as
hook feedback and continues the child with that prompt.
- `continue: false` stops the child turn. If `stopReason` is present,
Codex surfaces it as the stop reason.
# Lifecycle Scope
Only thread-spawned subagents run `SubagentStop`.
Internal/system subagents such as Review, Compact, MemoryConsolidation,
and Other do not run normal `Stop` hooks and do not run `SubagentStop`.
This avoids exposing synthetic matcher labels for internal
implementation paths.
# Stack
1. #22782: add `SubagentStart`.
2. This PR: add `SubagentStop`.
3. #22882: add subagent identity to normal hook inputs.
## Why
App-server clients need a way to update a thread's next-turn settings
without starting a turn, adding transcript content, or waiting for turn
lifecycle events. This gives settings UI a direct path for durable
thread settings while clients observe the eventual effective state
through a notification.
This is a simplified rework of PR
https://github.com/openai/codex/pull/22509. In particular, it changes
the `thread/settings/update` api to return immediately rather than
waiting and returning the effective (updated) thread settings. This
makes the new api consistent with `turn/start` and greatly reduces the
complexity of the implementation relative to the earlier attempt.
## What Changed
- Adds experimental `thread/settings/update` with partial-update request
fields and an empty acknowledgment response.
- Adds experimental `thread/settings/updated`, carrying full effective
`ThreadSettings` and scoped by `threadId` to subscribed clients for the
affected thread.
- Shares durable settings validation with `turn/start`, including
`sandboxPolicy` plus `permissions` rejection and `serviceTier: null`
clearing.
- Emits the same settings notification when `turn/start` overrides
change the stored effective thread settings.
- Regenerates app-server protocol schema fixtures and updates
`app-server/README.md`.
## Why
Pressing `Ctrl+C` or `Ctrl+D` in the TUI could make Codex pause during
shutdown when app-server background work still held outbound sender
clones.
Shutdown tracing against the current `~/.codex` path found three
relevant holders:
- `SkillsWatcher` kept its event-loop task alive until the shutdown
timeout path.
- `AppServerAttestationProvider` retained a strong
`Arc<OutgoingMessageSender>`, which could keep outbound teardown waiting
after the processor task had exited.
- A background `apps/list` task could still own an outbound sender when
shutdown began, causing the in-process app-server runtime to wait for
its outbound channel to close.
## What Changed
- Give `SkillsWatcher` an explicit shutdown `CancellationToken` and
cancel it from app-server teardown so its event loop drops the outbound
sender promptly.
- Change `AppServerAttestationProvider` to keep a
`Weak<OutgoingMessageSender>` and return immediately when it can no
longer be upgraded.
- Give `AppsRequestProcessor` a shutdown `CancellationToken` and cancel
in-flight background `apps/list` work during teardown.
## How to Test
1. Start Codex TUI from a real home configuration.
2. Press `Ctrl+C`.
3. Confirm Codex exits promptly instead of pausing during shutdown.
4. Repeat with `Ctrl+D` and confirm the same prompt exit path.
Focused manual trace validation from the investigation:
- Before the full fix, reproduced shutdown traces showed outbound
teardown waiting on lingering owners, including `attestation.provider=1`
and later `apps.list.task=1`.
- After the fix, fresh real-home `Ctrl+D` traces showed
`app_server.runtime.outbound_state_after_processor_join` with
`owners=none`, `app_server.runtime.wait_outbound_handle = 0ms`, and
total TUI app-server shutdown around `18ms`.
Targeted validation:
- `RUST_MIN_STACK=8388608 cargo test -p codex-app-server`
- Adds an explicit vertical marketplace kind for plugin/list that
fail-open fetches collection=vertical only when full remote plugins are
disabled.
- Renames the global remote marketplace/cache identity to
openai-curated-remote and materializes remote installs with backend
release versions and app manifests.
## Why
Clients need a typed permission-profile catalog instead of
reconstructing that state from config internals.
## What changed
- Added `permissionProfile/list` to the app-server v2 protocol with
cursor pagination and optional `cwd`.
- The list response includes built-in permission profiles plus
config-defined `[permissions.<id>]` profiles from the effective config
for the request context.
- Permission profiles keep optional `description` metadata for display
purposes.
- App-server docs and schema fixtures are updated for the new RPC.
## Why
`codex-app-server` is published as a standalone release binary, so it
should support the same basic version inspection behavior users expect
from command-line tools. This is independent of package assembly:
package metadata now comes from `codex-rs/Cargo.toml`, but the
standalone app-server binary should still answer `--version` directly.
## What changed
- Enables Clap's generated `--version` flag for the `codex-app-server`
binary by adding `#[command(version)]` to its top-level parser.
## Verification
- Ran `cargo run -p codex-app-server --bin codex-app-server --
--version` and verified it prints `codex-app-server 0.0.0`.
# Summary
Unix-socket app-server startup can currently race when multiple launch
attempts target the same `CODEX_HOME`. Those processes can overlap
before the control socket exists, which lets them enter SQLite state
initialization concurrently and reproduce the startup corruption pattern
seen in SSH mode.
This change makes the app-server own that singleton startup guarantee.
Unix-socket startup now takes a `CODEX_HOME`-scoped advisory lock before
SQLite initialization, runs the existing control-socket preparation
check while holding that lock, returns the established `AddrInUse` error
when another live listener already owns the socket, and releases the
lock once the new listener has bound its socket.
# Design decisions
- The singleton rule lives in `app-server --listen unix://`, not in a
desktop-only caller path, so every Unix-socket launch gets the same race
protection.
- A duplicate raw app-server launch returns an error instead of silently
succeeding. The attach operation remains `app-server proxy`, which
continues to connect to an already-running listener.
- The lock is held only across the dangerous startup window: socket
preparation, SQLite initialization, and socket bind. It is not held for
the app-server lifetime.
- Listener detection stays in `prepare_control_socket_path(...)`, so the
preexisting live-listener and stale-socket behavior remains the single
source of truth.
# Testing
Tests: targeted Unix-socket transport tests on the branch checkout, full
`codex-cli` build on `efrazer-db10`, and an SSH-style smoke on
`efrazer-db10` covering concurrent app-server starts, explicit
duplicate-start errors, and absence of SQLite startup-error matches in
launch logs.
## Summary
- move local-only app-server gating out of `MessageProcessor`
- let `fs/*`, `command/exec`, and `process/spawn` resolve local
availability inside their owning processors
- keep `fs/*` mounted for the future environment-param path while
preserving current no-local error behavior
## Validation
- not run locally per Codex repo guidance
## Summary
- Coerce `path: ""` to `None` at the v2 protocol params deserialization
boundary for `thread/resume` and `thread/fork`.
- Restore the pre-ThreadStore running-thread resume behavior: if
`threadId` is already running, rejoin it by id and treat a non-empty
`path` only as a consistency check; otherwise cold resume keeps `history
> path > threadId` precedence.
- Add protocol, resume, and fork regression coverage for empty path
payloads; refresh app-server schema fixtures for the clarified params
docs.

# What
`SubagentStart` runs once when Codex creates a thread-spawned subagent,
before that child sends its first model request. Thread-spawned
subagents use `SubagentStart` instead of the normal root-agent
`SessionStart` hook.
Configured handlers match on the subagent `agent_type`, using the same
value passed to `spawn_agent`. When no agent type is specified, Codex
uses the default agent type.
Hook input includes the normal session-start fields plus:
- `agent_id`: the child thread id.
- `agent_type`: the resolved subagent type.
`SubagentStart` may return `hookSpecificOutput.additionalContext`. That
context is added to the child conversation before the first model
request.
# Lifecycle Scope
Only thread-spawned subagents run `SubagentStart`.
Internal/system subagents such as Review, Compact, MemoryConsolidation,
and Other do not run normal `SessionStart` hooks and do not run
`SubagentStart`. This avoids exposing synthetic matcher labels for
internal implementation paths.
Also the `SessionStart` hook no longer fires for subagents, this matches
behavior with other coding agents' implementation
# Stack
1. This PR: add `SubagentStart`.
2. #22873: add `SubagentStop`.
3. #22882: add subagent identity to normal hook inputs.
## Why
Filesystem permission profiles used `none` for deny-read entries, which
is less direct than the action the entry actually represents. This
change makes `deny` the canonical filesystem permission spelling while
preserving compatibility for older configs that still send `none`.
## What changed
- rename `FileSystemAccessMode::None` to `Deny`
- serialize and generate schemas with `deny` as the canonical value
- retain `none` only as a legacy input alias for temporary config
compatibility
- update filesystem glob diagnostics and regression coverage to use the
canonical spelling
- refresh config and app-server schema fixtures to match the new wire
shape
## Validation
- `cargo test -p codex-protocol`
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-core config_toml_deserializes_permission_profiles
--lib`
- `cargo test -p codex-core
read_write_glob_patterns_still_reject_non_subpath_globs --lib`
Earlier in the session, a broad `cargo test -p codex-core` run reached
unrelated pre-existing failures in timing/snapshot/git-info tests under
this environment; the targeted surfaces touched by this PR passed
cleanly.
## Why
The v1 sub-agent tools are a single tool family, but they were exposed
as separate flat function tools. This makes the model-visible surface
less clearly grouped and leaves the legacy names in the same flat
namespace as newer agent tooling.
## What
- Wraps the v1 `spawn_agent`, `send_input`, `resume_agent`,
`wait_agent`, and `close_agent` specs in the `multi_agent_v1` namespace.
- Registers the corresponding handlers with namespaced runtime tool
names.
- Updates tool-planning, deferred tool search, and sub-agent
notification tests to assert the namespace shape and child `spawn_agent`
lookup.
## Verification
- Updated `codex-core` coverage for the v1 multi-agent tool plan,
deferred tool search output, and sub-agent tool descriptions.
## Why
App and skill toggles are user config mutations too. When the TUI is
attached to a remote app server, writing those toggles into the local
`config.toml` makes the UI report success without updating the server
that actually owns the session.
This is **[2 of 4]** in a stacked series that moves TUI-owned config
mutations onto app-server APIs.
## What changed
- Routed app enable/disable persistence through app-server config batch
writes.
- Routed skill enable/disable persistence through `skills/config/write`.
- Avoided refreshing local config from disk after these writes when the
TUI is connected to a remote app server.
## Config keys affected
- `apps.<app_id>.enabled`
- `apps.<app_id>.disabled_reason`
- `[[skills.config]]` entries keyed by `path`, with `enabled = false`
used for persisted disables
## Suggested manual validation
- Connect the TUI to a remote app server, disable an app, reconnect, and
confirm the app remains disabled from remote config rather than local
disk state.
- Re-enable the same app and confirm both `apps.<app_id>.enabled` and
`apps.<app_id>.disabled_reason` are cleared remotely.
- Disable a skill in the manage-skills UI and confirm a remote
`[[skills.config]]` disable entry appears.
- Re-enable that skill and confirm the disable entry is removed and the
effective enabled state updates without relying on local config reloads.

## Why
`turn/start` already accepts an input array on the wire, including an
empty array, but core treated empty input as a no-op before the turn
could reach the model. App-server clients need to be able to start a
real turn even when there is no new user message, for example to let the
model proceed from existing thread context.
## What changed
- Removed the `run_turn` early return that skipped empty-input turns
when there was no pending input.
- Kept empty active-turn steering rejected by moving the `steer_input`
empty-input check until after core has determined whether there is an
active regular turn.
- Empty regular turns now refresh `previous_turn_settings` like other
regular turns, so follow-up context injection state advances
consistently.
- Added an app-server v2 integration test proving `turn/start` with
`input: []` emits started/completed notifications, sends one Responses
request, and does not synthesize an empty user message.
## Validation
- `cargo test -p codex-app-server --test all

## Why
Thread goals are moving toward extension-owned runtime behavior, but
their persisted state was still stored in the shared state database.
This makes the goal store harder to isolate and keeps future storage
splits tied to ad hoc runtime plumbing.
This PR gives goals their own SQLite database while keeping the existing
`StateRuntime` entry point. The goal is to make this the pattern for
adding more dedicated runtime databases later.
This also reduce load on existing DB and reduce contention
## Limitation
Thread preview from goal is not supported anymore. I'm looking into this
[EDIT]: solved
## What changed
- Added a dedicated `goals_1.sqlite` database with its own
`goals_migrations` directory.
- Moved `thread_goals` creation into the goals DB migration set.
- Dropped the old `thread_goals` table from the main state DB with a
normal state migration. There is intentionally no backfill for existing
goal rows.
- Changed `GoalStore` to be backed only by the goals DB pool.
- Removed the old goal-write side effect that filled empty
`threads.preview` values from the goal objective.
- Added shared runtime DB path metadata so startup, telemetry, `codex
doctor`, and repair handling can include future DBs without bespoke path
lists.
- Updated Bazel compile data so the new goals migration directory is
available to `sqlx::migrate!`.

**Stack position:** [5 of 7]
## Summary
This PR adds `Op::ThreadSettings`, a queued settings-only update
mechanism for changing stored thread settings without starting a new
turn. It also removes the legacy `Op::OverrideTurnContext` in the same
layer, so reviewers can see the replacement and deletion together.
## Changes
- Add `Op::ThreadSettings` for settings-only queued updates.
- Emit `ThreadSettingsApplied` with the effective thread settings
snapshot after core applies an update.
- Route settings-only updates through the same submission queue as user
input.
- Migrate remaining `OverrideTurnContext` tests and callers to the
queued `Op::ThreadSettings` path.
- Delete `Op::OverrideTurnContext` from the core protocol and submission
loop.

**Stack position:** [1 of 7]
## Summary
The first three PRs in this stack are a cleanup pass before the actual
thread settings API work.
Today, core has several overlapping "user input" ops: `UserInput`,
`UserInputWithTurnContext`, and `UserTurn`. They differ mostly in how
much next-turn state they carry, which makes the later queued thread
settings update harder to reason about and review.
This PR starts that cleanup by adding the shared
`ThreadSettingsOverrides` payload and allowing `Op::UserInput` to carry
it. Existing variants remain in place here, so this layer is mostly a
behavior-preserving API shape change plus mechanical constructor
updates.
## End State After PR3
By the end of PR3, `Op::UserInput` is the only "user input" core op. It
can carry optional thread settings overrides for callers that need to
update stored defaults with a turn, while callers without updates use
empty settings. `Op::UserInputWithTurnContext` and `Op::UserTurn` are
deleted.
## End State After PR5
By the end of PR5, core will have only two ops for this area:
- `Op::UserInput` for user-input-bearing submissions.
- `Op::ThreadSettings` for settings-only updates.

## Summary
- mark `ToolSearch` as removed and ignore stale config writes for its
legacy key
- make search tool exposure depend only on model capability, not a
feature toggle
- remove app-server enablement support and prune now-obsolete test
coverage/setup
## Verification
- `cargo test -p codex-features`
- `cargo test -p codex-tools`
- `cargo test -p codex-core search_tool_requires_model_capability`
- `cargo test -p codex-app-server experimental_feature_enablement_set_`
## Notes
- This keeps the legacy config key as a no-op for compatibility while
removing the ability to toggle the behavior off cleanly.
- No developer-facing docs update outside the touched app-server README
was needed.
## 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`

## Description
This PR makes `codex remote-control` behave like a foreground CLI
command by default. Running it now starts remote control, waits for
readiness, prints a clear status message with the machine name, and
stays alive until Ctrl-C.
Users who want daemon behavior can use `codex remote-control start`, and
`codex remote-control stop` now prints concise human-readable output.
`--json` remains available for scripts.
Implementation-wise, this now verifies the real app-server state instead
of just assuming startup worked. The CLI starts or connects to
app-server, probes its control socket, calls the `remoteControl/enable`
API, and waits for the remote-control status response/notification
before printing success.
For daemon mode, `codex remote-control start` also reports which managed
app-server binary was used, including its path and best-effort `codex
--version`, so failures are easier to diagnose.
## Examples
Example output:
```
> codex remote-control
Starting app-server with remote control enabled...
This machine is available for remote control as com-97826.
Press Ctrl-C to stop.
```
Error case using daemon (currently expected based on our publicly
released CLI version):
```
> ./target/debug/codex remote-control start
Starting app-server daemon with remote control enabled...
Error: app server did not become ready on /Users/owen/.codex/app-server-control/app-server-control.sock
Daemon used app-server:
path: /Users/owen/.codex/packages/standalone/current/codex
version: 0.130.0
Managed app-server stderr (/Users/owen/.codex/app-server-daemon/app-server.stderr.log):
error: unexpected argument '--remote-control' found
Usage: codex app-server [OPTIONS] [COMMAND]
For more information, try '--help'.
Caused by:
0: failed to connect to /Users/owen/.codex/app-server-control/app-server-control.sock
1: No such file or directory (os error 2)
```
## What changed
- `codex remote-control` now runs remote control in the foreground and
prints a Ctrl-C stop hint.
- `codex remote-control start` starts the daemon and waits for remote
control readiness before reporting success.
- `codex remote-control stop` reports stopped/not-running status in
plain language.
- Startup failures now include recent managed app-server stderr to make
daemon issues easier to diagnose.
- Added coverage for CLI output, readiness waiting, foreground shutdown,
and stderr log tailing.
## Why
`experimentalFeature/list` reports effective feature enablement, but
currently does not resolve it against a working directory where
project-local config.toml files can exist and toggle on/off features
when merged into the effective config after resolving the various config
layers. That means we effectively (and incorrectly) ignore features set
in project-local config.
To address that, this PR exposes an optional `thread_id` param which
allows us to load the thread's `cwd.
## Testing
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-app-server experimental_feature_list`
Addresses #22833, #22245, #23067
## Why
`/goal` can keep synthesizing turns even when the next turn cannot make
meaningful progress. Hard usage exhaustion can replay failing turns, and
repeated permission or external-resource blockers can keep burning
tokens while waiting for user or system intervention.
## What changed
- Add resumable `blocked` and `usageLimited` goal states. As with
`paused`, goal continuation stops with these states.
- Move to `usageLimited` after usage-limit failures.
- Allow the built-in `update_goal` tool to set `blocked` only under
explicit repeated-impasse guidance. Updated goal continuation prompt to
specify that agent should use `blocked` only when it has made at least
three attempts to get past an impasse.
Most of the files touched by this PR are because of the small app server
protocol update.
## Validation
I manually reproduced a number of situations where an agent can run into
a true impasse and verified that it properly enters `blocked` state. I
then resumed and verified that it once again entered `blocked` state
several turns later if the impasse still exists.
I also manually reproduced the usage-limit condition by creating a
simulated responses API endpoint that returns 429 errors with the
appropriate error message. Verified that the goal runtime properly moves
the goal into `usageLimited` state and TUI UI updates appropriately.
Verified that `/goal resume` resumes (and immediately goes back into
`ussageLImited` state if appropriate).
## Follow-up PRs
Small changes will be needed to the GUI clients to properly handle the
two new states.
## Why
Thread goal persistence is being prepared for a dedicated storage
boundary. Before that split, goal-specific reads, writes, accounting,
and cleanup were exposed directly on `StateRuntime`, so core and
app-server callsites stayed coupled to the full runtime instead of a
goal-specific store.
This PR introduces that boundary without changing the goal wire API or
current persistence behavior. Callers now go through
`StateRuntime::thread_goals()` and the new `GoalStore`, while
`GoalStore` still uses the existing state DB pool underneath.
## What changed
- Added `GoalStore` in `state/src/runtime/goals.rs` and exposed it from
`StateRuntime` via `thread_goals()`.
- Moved thread-goal reads, writes, status updates, pause, delete, and
usage accounting onto `GoalStore`.
- Updated core session goal handling, app-server goal RPCs, resume
snapshots, and goal tests to use the store boundary.
- Kept thread deletion responsible for cascading goal cleanup by
deleting the goal through the store only after a thread row is removed.
## Testing
- Existing goal persistence, resume, and accounting tests were updated
to exercise the new `GoalStore` access path.
## Summary
- add app-server `plugin/installed` for mention-oriented plugin loading
- return installed plugins plus explicitly requested install-suggestion
rows
- keep remote handling on installed-state data instead of the broad
catalog listing path
## Why
The `@` mention surface only needs plugins that are usable now, plus a
small product-approved set of install suggestions. It does not need the
full catalog-shaped `plugin/list` payload that the Plugins page uses.
## Validation
- `just write-app-server-schema`
- `just fmt`
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-core-plugins`
- `cargo test -p codex-app-server --test all plugin_installed_`
## Notes
- The package-wide `cargo test -p codex-app-server` run still hits an
existing unrelated stack overflow in
`in_process::tests::in_process_start_clamps_zero_channel_capacity`.
- Companion webview PR: https://github.com/openai/openai/pull/915672
## Why
The TUI can run against a remote app server, but several high-traffic
settings still persisted by editing the local config file. That sends
remote sessions' preference writes to the wrong machine and lets local
disk state drift from the app-server-owned config.
This is **[1 of 4]** in a stacked series that moves TUI-owned config
mutations onto app-server APIs.
## What changed
- Added a small TUI helper for typed app-server config writes.
- Routed primary interactive preference writes through
`config/batchWrite`.
- Preserved existing profile scoping for settings that already support
`profiles.<profile>.*` overrides.
## Config keys affected
- `model`
- `model_reasoning_effort`
- `personality`
- `service_tier`
- `plan_mode_reasoning_effort`
- `approvals_reviewer`
- `notice.fast_default_opt_out`
- Profile-scoped equivalents under `profiles.<profile>.*`
## Suggested manual validation
- Connect the TUI to a remote app server, change `model` and
`model_reasoning_effort`, reconnect, and confirm the remote config
retained both values while the local `config.toml` did not change.
- Change `personality`, `plan_mode_reasoning_effort`, and the explicit
auto-review selection, then reconnect and confirm those choices persist
through the app server.
- Clear the service tier back to default and confirm `service_tier` is
cleared while `notice.fast_default_opt_out = true` is persisted
remotely.
- Repeat one setting change with an active profile and confirm the write
lands under `profiles.<profile>.*`.

## 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.
## 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`.
## Why
To help improve `codex remote-control` CLI UX which I plan to do in a
followup, this PR adds `server-name` to the various remote control APIs:
- `remoteControl/enable`
- `remoteControl/disable`
- `remoteControl/status/changed`
Also, add a `remoteControl/status/read` API. This will be helpful in the
Codex App.
## 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.

## Why
Memory prompt injection should be owned by the extension path that
app-server composes at runtime, not by an inlined special case inside
`codex-core`. This keeps `codex-core` focused on session orchestration
while allowing the memories extension to own its app-server prompt
behavior.
## What Changed
- Registers `codex-memories-extension` in the app-server extension
registry.
- Moves the memory developer-instruction injection out of
`core/src/session/mod.rs` and into the memories extension prompt
contributor.
- Adds config-change handling so the extension keeps its per-thread
memory settings in sync after startup.
- Leaves memories read/retrieval tools unregistered for now so this PR
only changes prompt injection.
- Removes the stale `cargo-shear` ignore now that app-server depends on
the extension crate.
## Validation
Not run locally; validation is left to CI.
## 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.

## Summary
- reserve an explicit opaque `desktop` namespace in `ConfigToml`
- expose `desktop` directly in the app-server v2 `config/read` response
- keep `config/value/write` and `config/batchWrite` as the only mutation
seam for paths like `desktop.someKey`
- regenerate the config/app-server schema outputs and document the new
contract
## Why
The desktop settings work wants one durable, user-editable home for
app-owned preferences in `~/.codex/config.toml`, without forcing Rust to
model every individual desktop setting key.
This PR is only the enabling Rust/app-server layer. It gives the
Electron app a first-class config namespace it can read and write
through the existing config APIs, while leaving the actual desktop
migration to the app PR.
## Behavior and design notes
- **Opaque but explicit:** `desktop` is first-class at the typed config
root, while its children remain app-owned and open-ended.
- **Strict validation still works:** arbitrary nested `desktop.*` keys
are accepted instead of being rejected as unknown config.
- **Existing config APIs stay the seam:** `config/read` returns the bag,
and dotted writes such as `desktop.someKey` continue to flow through
`config/value/write` / `config/batchWrite` rather than a bespoke RPC.
- **No new consumer behavior:** Core/TUI do not start depending on
desktop preferences. This only preserves and exposes the namespace for
callers that intentionally use it.
- **Same persistence machinery:** hand-edited `config.toml` keeps using
the existing TOML edit/write path; this PR does not introduce a second
serializer or side channel.
- **TOML-friendly values:** the namespace is intended for ordinary
JSON-shaped setting values that map cleanly into TOML: strings, numbers,
booleans, arrays, and nested object/table values. This PR does not add
special handling for TOML-only edge cases such as datetimes.
## Layering semantics
Reads keep using the ordinary effective config pipeline, so `desktop`
participates in the same layered `config/read` behavior as the rest of
`ConfigToml`. Writes still target user config through the existing
config service.
## Why this is the shape
The alternative would be teaching Rust about each desktop setting as it
is added. That would make ordinary app preferences into a cross-repo
change, which is exactly the coupling we want to avoid.
This keeps the contract small:
1. Rust owns one opaque `desktop` namespace in `config.toml`.
2. The desktop app owns the schema and meaning of individual keys inside
it.
3. The existing config APIs remain the transport and mutation surface.
That is the piece the desktop settings PR needs in order to move forward
cleanly.
## Verification
- `cargo test -p codex-config strict_config_accepts_opaque_desktop_keys`
- `cargo test -p codex-core
desktop_toml_round_trips_opaque_nested_values`
- `cargo test -p codex-core config_schema_matches_fixture`
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-app-server --test all desktop_settings`
## 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.

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.
