## Why
Fixes#20145.
`config/value/write` treats a JSON `null` value as a request to clear
the config key. Clearing a key that is already absent should be
idempotent, but clearing a nested key such as `features.personality`
from an empty `config.toml` returned `configPathNotFound` because
`clear_path` treated the missing `features` parent table as an error.
That makes app-server reset flows brittle because clients have to read
first and avoid sending a clear request unless the parent path already
exists.
## What Changed
- Updated app-server config clearing so missing intermediate tables, or
non-table parents, are treated as an unchanged no-op.
- Removed the now-unreachable `MergeError::PathNotFound` path from
config write merging.
- Added a regression test covering `features.personality = null` against
an empty user config.
## Verification
- `cargo test -p codex-app-server clear_missing_nested_config_is_noop`
- `cargo test -p codex-app-server` was run; the config manager unit
suite passed, but one unrelated integration test failed because
`turn_start_emits_thread_scoped_warning_notification_for_trimmed_skills`
expected `7` trimmed skills and observed `8`.
- `just fix -p codex-app-server`
1. Adds v2 plugin/share/save, plugin/share/list, and plugin/share/delete
RPCs.
2. Implements save by archiving a local plugin root, enforcing a size
limit, uploading through the workspace upload flow, and supporting
updates via remotePluginId.
3. Lists created workspace plugins
4. Deletes a previously uploaded/shared plugin.
## Why
After `hooks/list` exposes the hook inventory, clients need a way to
persist user hook preferences, make those changes effective in
already-open sessions, and distinguish user-controllable hooks from
managed requirements without adding another bespoke app-server write
API.
## What
- Extends `hooks/list` entries with effective `enabled` state.
- Persists user-level hook state under `hooks.state.<hook-id>` so the
model can grow beyond a single boolean over time.
- Uses the existing `config/batchWrite` path for hook state updates
instead of introducing a dedicated hook write RPC.
- Refreshes live session hook engines after config writes so
already-open threads observe updated enablement without a restart.

## Reviewer Notes
The generated schema files account for much of the raw diff. The core
behavior is in:
- `hooks/src/config_rules.rs`, which resolves per-hook user state from
the config layer stack.
- `hooks/src/engine/discovery.rs`, which projects effective enablement
into `hooks/list` from source-derived managedness.
- `config/src/hook_config.rs`, which defines the new `hooks.state`
representation.
- `core/src/session/mod.rs`, which rebuilds live hook state after user
config reloads.

## Review Notes
The generated schema files account for most of the raw diff, these files
have the core change:
- `hooks/src/engine/discovery.rs` builds the inventory entries during
hook discovery while leaving runtime handlers focused on execution.
- `app-server/src/codex_message_processor.rs` wires `hooks/list` into
the app-server flow for each requested `cwd`.
- `app-server-protocol/src/protocol/v2.rs` defines the new v2
request/response payloads exposed on the wire.
### Core Changes
`core/src/plugins/manager.rs` adds `plugins_for_layer_stack(...)` so
`skills/list` and `hooks/list`can resolve plugin state for each
requested `cwd`

Plugin MCP servers are loaded from plugin manifests rather than
top-level `[mcp_servers]`, so their tool approval preferences need to be
stored and applied through the owning plugin config. Without this,
choosing "Always allow" for a plugin MCP tool could write a preference
that was not reliably used on later tool calls.
## Summary
- Add plugin-scoped MCP policy config under
`plugins.<plugin>.mcp_servers`, including server enablement, tool
allow/deny lists, server defaults, and per-tool approval modes.
- Overlay plugin MCP policy onto manifest-provided server configs when
plugins are loaded.
- Route persistent "Always allow" writes for plugin MCP tools back to
the owning `plugins.<plugin>.mcp_servers.<server>.tools.<tool>` config
entry.
- Reload user config after persisting an approval and make the plugin
load cache config-aware so stale plugin MCP policy is not reused after
`config.toml` changes.
- Regenerate the config schema and add coverage for plugin MCP policy
loading, approval lookup, persistence, and stale-cache prevention.
## Testing
- `cargo test -p codex-config`
- `cargo test -p codex-core-plugins`
- `cargo test -p codex-core --lib plugin_mcp`
## Why
The precursor PR keeps successful client responses typed until
app-server's outgoing response seam. This follow-up uses that seam to
move successful client-response analytics out of individual handlers and
into the shared sender path, while keeping filtering decisions inside
`codex-analytics`.
## What changed
- Emit successful client-response analytics centrally from
`OutgoingMessageSender::send_response`.
- Remove duplicate handler-local response tracking for the current
thread/turn lifecycle responses.
- Keep analytics ingestion selective inside `AnalyticsEventsClient`, so
unrelated client traffic is ignored before cloning or boxing.
- Collapse client-response analytics facts onto one typed path and
normalize payloads in the reducer.
- Add direct client-filter coverage plus sender-level coverage for the
centralized forwarding path.
## Verification
- `cargo test -p codex-analytics`
- `cargo test -p codex-app-server outgoing_message::tests --lib`
## Summary
- Fetch remote plugin detail before sending the uninstall request.
- Use the detail response to derive the marketplace namespace and plugin
name for cache cleanup.
- Stop the uninstall before the backend POST if detail lookup fails, so
backend state and local cache state do not diverge.
## Testing
- `just fmt`
- `cargo test -p codex-app-server plugin_uninstall`
- `cargo test -p codex-core-plugins`
- `git diff --check`
## Why
`pr17088` adds typed server-originated request/response plumbing, but
successful client responses are still erased into bare JSON-RPC `result`
values before app-server can make any typed decision about them.
This precursor PR keeps successful client responses typed until the
outgoing response seam. It is intentionally limited to
protocol/app-server plumbing so the analytics behavior change can review
separately on top.
## What changed
- Add `ClientResponsePayload` as the pre-serialization client response
body type.
- Route app-server successful response paths through the typed payload
seam while preserving existing handler-local analytics behavior.
- Keep `InterruptConversation` JSON-RPC-only because it has no
`ClientResponse` variant.
- Move the new payload conversion tests into a dedicated protocol test
module.
## Verification
- `cargo check -p codex-app-server`
- `cargo test -p codex-app-server-protocol`
## Why
[#17088](https://github.com/openai/codex/pull/17088) changed
`OutgoingMessageSender::new` to require an `AnalyticsEventsClient`, but
one `command_exec` test added earlier on `main` still called the old
one-argument constructor. That leaves current `main` failing to compile
in Bazel and argument-comment-lint jobs.
## What changed
- Pass `AnalyticsEventsClient::disabled()` to the missed
`OutgoingMessageSender::new` test call site in `command_exec.rs`.
## Verification
- `cargo test -p codex-app-server
timeout_or_cancellation_reports_cancellation_without_timeout_exit_code`
## Why
Codex analytics needs a typed seam for app-server-originated
request/response traffic so future tool-approval analytics can consume
those facts without adding bespoke callsite tracking each time. Server
responses arrive as JSON-RPC `id + result` payloads, so analytics has to
reconstruct the matching typed response from the original typed request
while that request context still exists in app-server.
This also puts analytics on the app-server outbound path, which needs to
avoid keeping the runtime alive during shutdown. The final ownership fix
keeps the normal strong auth-manager retention in analytics and makes
the external-auth refresh bridge hold a weak back-reference to
`OutgoingMessageSender`, breaking the runtime cycle at the bridge
boundary instead of exposing retention policy through the analytics
client API.
## What changed
- Adds typed `ServerRequest` and `ServerResponse` analytics facts, plus
`AnalyticsEventsClient::track_server_request` and
`track_server_response`.
- Renames the existing client-side facts to `ClientRequest` and
`ClientResponse` so reducers can distinguish client-to-server traffic
from server-to-client traffic.
- Adds `ServerRequest::response_from_result`, allowing a stored typed
request to decode the matching typed server response from a raw JSON-RPC
result payload.
- Threads `AnalyticsEventsClient` through `OutgoingMessageSender` and
records targeted server requests, replayed targeted requests, and
matching targeted responses with the responding connection id needed for
correlation.
- Intentionally leaves broadcast server requests/responses out of
analytics for now because the current model is per connection, while
broadcasts fan one logical request out across multiple connections.
- Breaks the app-server shutdown cycle by storing
`Weak<OutgoingMessageSender>` in `ExternalAuthRefreshBridge` and
upgrading it only when an external-auth refresh is actually requested.
- Keeps reducer ingestion of the new server-side facts as no-ops for
now; this PR is plumbing for later tool-approval analytics work.
## Verification
- `cargo test -p codex-analytics`
- `cargo test -p codex-app-server outgoing_message::tests::`
- Covers typed-response reconstruction plus the targeted, replayed,
broadcast-exclusion, and response-attribution analytics paths.
## Follow-up
This PR intentionally stops at ingestion plumbing, so `ServerRequest`
and `ServerResponse` facts are still reducer no-ops. Once a follow-up PR
adds real downstream analytics output for those facts:
- replace the temporary pre-reducer observation seam with reducer tests
for the emitted event shape;
- add end-to-end coverage in `app-server/tests/suite/v2/analytics.rs`
for the real app-server workflow and captured analytics payload;
- remove the temporary sender-level observer tests added here in favor
of the real-output coverage above.

## Why
This bug is exposed by Guardian/auto-review approvals. With the managed
network proxy enabled, a blocked network request can be reported back
through the network approval service as an approval denial after the
command has already started. Before this change, the shell and unified
exec runtimes registered those network approval calls, but did not have
a way to observe an async proxy denial as a cancellation/failure signal
for the running process.
The result was confusing: Guardian/auto-review could correctly deny
network access, but the command path could keep running or unregister
the approval without surfacing the denial as the command failure.
## What Changed
- `NetworkApprovalService` now attaches a cancellation token to active
and deferred network approvals.
- Proxy-denial outcomes are recorded only for active registrations,
cancel the owning token, and are consumed when the approval is
finalized.
- The shell runtime combines the normal command timeout with the
network-denial cancellation token.
- Unified exec stores the deferred network approval object, terminates
tracked processes when the proxy denial arrives, and returns the denial
as a process failure while polling or completing the process.
- Tool orchestration passes the active network approval cancellation
token into the sandbox attempt and preserves deferred approval errors
instead of silently unregistering them.
- App-server `command/exec` now handles the combined
timeout-or-cancellation expiration variant used by the runtime.

- `cargo clippy -p codex-app-server --all-targets -- -D warnings`
- `cargo clippy -p codex-core --all-targets -- -D warnings`

## Summary
- include the live auto-review trunk rollout when `/feedback` uploads
logs
- upload that attachment as

from the parent rollout
- show the same auto-review attachment name in the TUI consent popup
## Scope
- this only covers the live cached auto-review trunk for the current
parent thread
- it does not add durable historical parent->auto-review lookup
- it does not add persisted rollout support for ephemeral parallel
review forks

- `cargo test -p codex-tui` currently hits pre-existing `status::*`
snapshot drift unrelated to this change
## Follow-Up
- persist parallel auto-review fork sessions so /feedback can include
their rollout history too
- attach each persisted fork as its own clearly named file, for example
auto-review-rollout-<parent-thread-id>-fork <n>.jsonl, instead of
merging multiple Guardian sessions into one attachment
- keep the same live-session-only scope initially; durable historical
parent -> auto-review lookup can remain a separate decision if we later
need feedback from resumed sessions

## Summary
- Rewrite migrated external-agent hook commands by replacing the full
hook script path token instead of only the `.claude/hooks/` segment.
- Preserve quoting around the full rewritten target path so script names
with spaces, absolute paths, and shell operators/redirection continue to
work.
- Apply `.claude/settings.local.json` over `.claude/settings.json` for
config, MCP, and plugin migration so local scope matches Claude settings
precedence.
- Skip legacy command markdown without `description` frontmatter,
including README-style docs under `.claude/commands`.
## Root Cause
The previous hook rewrite handled `.claude/hooks/` as a substring
replacement. For absolute source commands, that left the original
project-root prefix before the newly quoted `.codex/hooks` directory,
producing invalid commands like
`project/'project/.codex/hooks'/script.sh`.
The migration also only used project `settings.json` for
config/MCP/plugin decisions, so local settings such as
`disabledMcpjsonServers` could be ignored even though Claude gives local
settings higher precedence than project settings.

## Summary
- Change `EnvironmentProvider` to return concrete `Environment`
instances instead of `EnvironmentConfigurations`.
- Make `DefaultEnvironmentProvider` provide the provider-visible `local`
environment plus optional `remote` environment from

explicit local environment for `local_environment()` fallback paths.

follow up of #19442. The app server now exposes provider-derived bounds
through a new v2 `modelProvider/read` method. The response reports the
configured provider map key as `modelProvider` and returns the effective
capability booleans so clients can align their UI with the same
provider-owned limits used by core.
Fixes test that often fails locally when running `cargo test`
- Add an app-server test helper that combines managed-config isolation
with custom env overrides.
- Isolate `HOME` / `USERPROFILE` in plugin-list workspace settings tests
so host home marketplaces do not affect results.
## Why
This PR expands the migration path so Codex can detect and import MCP
server config, hooks, commands, and subagents configs in a Codex-native
shape.
## What changed
- Added a `codex-external-agent-migration` crate that owns conversion
logic for external-agent MCP servers, hooks, commands, and subagents.
- Extended the app-server external-agent config detection/import API
with migration item types for MCP server config, hooks, commands, and
subagents.
## Migration strategy
The migration is intentionally conservative: Codex only imports
external-agent config that can be represented safely in Codex today.
Unsupported or ambiguous config is skipped instead of being partially
translated into behavior that may not match the source system.
- **MCP servers**: import supported stdio and HTTP MCP server
definitions into `mcp_servers`. Disabled servers and servers filtered
out by source `enabledMcpjsonServers` / `disabledMcpjsonServers` are
skipped. Project-scoped MCP entries from `.claude.json` are included
when they match the repo path.
- **Hooks**: import only supported command hooks into
`.codex/hooks.json`. Unsupported hook features such as conditional
groups, async handlers, prompt/http hooks, or unknown fields are
skipped. Referenced hook scripts are copied into `.codex/hooks/`,
preserving any existing target scripts.
- **Commands**: import supported external commands as Codex skills under
`.agents/skills/source-command-*`. Commands that rely on source runtime
expansion such as `$ARGUMENTS`, `$1`, `@file` references, shell
interpolation, or colliding generated names are skipped.
- **Subagents**: import valid subagent Markdown files into
`.codex/agents/*.toml` when they have the minimum Codex agent fields.
Source model names are not migrated, so imported agents keep the user’s
Codex default model; compatible reasoning effort and sandbox mode are
migrated when present.
- **Skills and project guidance**: copy missing skill directories into
`.agents/skills` and migrate `CLAUDE.md` guidance into `AGENTS.md`,
rewriting source-agent terminology to Codex terminology where
appropriate.
- **Detection details**: detected migration items include lightweight
details for UI preview, such as MCP server names, hook event names,
generated command skill names, and subagent names. Import still
recomputes from disk instead of trusting details as the source of truth.
- Adds focused coverage for the new migration behavior and app-server
import flow.

## Why
Remote-control app-server enrollments have both an internal server id
and the environment id exposed to remote-control clients. App-server
clients need one current status snapshot that says whether remote
control is usable and which environment id, if any, is exposed.
A temporary websocket disconnect is not itself an identity change.
Account changes, stale enrollment invalidation, successful
re-enrollment, and missing ChatGPT auth are meaningful status changes.
Disabled remote control remains `disabled` regardless of auth or SQLite
state. SQLite startup failure disablement and enrollment persistence
failures are handled in #20068; this PR reports the resulting effective
status to clients.
## What changed
- Adds v2 `remoteControl/status/changed` carrying `state` and
`environmentId`.
- Adds `RemoteControlConnectionState` values: `disabled`, `connecting`,
`connected`, and `errored`.
- Exposes remote-control status updates through `RemoteControlHandle`
using a Tokio watch channel.
- Always sends the current remote-control status snapshot to newly
initialized app-server clients.
- Broadcasts status changes to initialized app-server clients when state
or environment id changes.
- Treats missing ChatGPT auth as an `errored` status while leaving it
retryable because auth can change at runtime.
- Clears `environmentId` when enrollment is cleared for account changes,
auth loss, stale backend invalidation, or disabled remote control.
- Updates app-server protocol schema fixtures, generated TypeScript,
app-server README, remote-control tests, and TUI exhaustive notification
matches.
## Stack
- Builds on #20068.
## Verification
- `just write-app-server-schema`
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-app-server transport::remote_control --lib`
- `cargo check -p codex-tui`
- `just fix -p codex-app-server-protocol`
- `just fix -p codex-app-server`
- `just fix -p codex-tui`
Right now, if Codex winds up in a state with auth but it can't refresh
the token, the user is left with an unhelpful message that says to log
out and log back in again.
Ultimately, we should prevent that from happening but if it does,
returning None will allow the caller to redirect the user back to the
login page
## Why
Remote control depends on the app-server SQLite state DB for persisted
enrollment identity. If the state DB cannot be opened at startup,
continuing with remote control enabled leaves the process in a
misleading state where enrollment identity cannot be read or persisted.
Feature-disabled remote control remains disabled regardless of SQLite
state. This only changes the case where remote control is requested but
the SQLite state DB is unavailable.
## What changed
- Logs SQLite state DB initialization failures instead of dropping the
error silently.
- Treats remote control as effectively disabled when the SQLite state DB
is unavailable.
- Prevents `RemoteControlHandle::set_enabled(true)` from enabling remote
control later in the same process if the state DB was unavailable at
startup.
- Keeps the existing behavior that disabled remote control does not
validate or connect to the remote-control URL.
- Makes persisted enrollment load/update failures propagate as
remote-control errors instead of silently falling back to in-memory
state.
- Makes the direct websocket connection path fail when called without a
SQLite state DB.
- Adds coverage for startup without a state DB, later handle enablement
with no state DB, and direct websocket connection without a state DB.
## Verification
- `cargo test -p codex-app-server transport::remote_control --lib`
- `just fix -p codex-app-server`
## Why
Initialized app-server RPCs no longer need to bottleneck behind one
request processor path. Running them concurrently improves
responsiveness, but several request families still mutate shared state
or depend on ordered side effects. Those stateful families need an
auditable serialization contract so concurrency does not reorder thread,
config, auth, command, watcher, MCP, or similar state transitions.
This PR keeps that boundary explicit: stateful work is serialized by the
smallest useful key, while intentionally read-only or externally
concurrent work remains unkeyed. In particular, `thread/list` and
`thread/turns/list` explicitly have no serialization because they
primarily read append-only rollout storage and should continue to be
served concurrently.
## What changed
- Adds `ClientRequest::serialization_scope()` in `app-server-protocol`
and requires every client request definition to declare its
serialization behavior.
- Introduces keyed request scopes for thread, thread path, command exec
process, fuzzy search session, fs watch, MCP OAuth, and global state
buckets such as config, account auth, memory, and device keys.
- Routes initialized app-server RPCs through per-key FIFO serialization
while allowing unkeyed initialized requests to run concurrently.
- Cancels in-flight initialized RPC work when the connection disconnects
or the app-server exits so spawned request tasks do not outlive their
session.
- Adds focused coverage for representative keyed and unkeyed
serialization scopes, including explicitly concurrent
`thread/turns/list` behavior.
## Validation
- Added protocol tests for representative keyed serialization scopes and
intentionally unkeyed request families.
- Added app-server request serialization tests covering per-key FIFO
behavior, concurrent unkeyed execution, disconnect shutdown, and config
read-after-write ordering.
- Local focused protocol validation after the latest rebase is currently
blocked by packageproxy failing to resolve locked `rustls-webpki
0.103.13`; CI is expected to provide the full validation signal.
## Summary
This extends external agent detection/import beyond config artifacts so
Codex can detect recent sessions files from the external agent home and
import them into Codex rollout history.
## What changed
- Added a focused `external_agent_sessions` module for:
- session discovery
- source-record parsing
- rollout construction
- import ledger tracking
- Wired session detection/import into the app-server external agent
config API.
- Added compaction handling so large imported sessions can be resumed
safely before the first follow-up turn.
## Testing
Added coverage for:
- recent-session detection
- custom-title handling
- recency filtering
- dedupe and re-detect-after-source-change behavior
- visible imported turn construction
- backward-compatible import payload deserialization
- end-to-end RPC import flow
- rejection of undetected session paths
- repeat-import behavior
- large-session compaction before first follow-up
Ran:
- `cargo test -p codex-app-server external_agent_config_import_ --test

## Why
Memory startup was tied to thread lifecycle events such as create, load,
and fork. That can run memory work before a thread receives real user
input, and it makes startup cost scale with thread management instead of
actual turns. Moving the trigger to `thread/sendInput` keeps memory
startup aligned with the first real user turn and lets it use the
current thread config at turn time.
The idea is to prevent ghost cost due to pre-warm triggered by the app
Turn-based startup can also make global phase-2 consolidation easier to
request repeatedly, so this adds a success cooldown and tightens the
default startup scan window.
## What Changed
- Start `codex_memories_write::start_memories_startup_task` after a
non-empty `thread/sendInput` turn is submitted, instead of from thread
create/load/fork paths:
d4a6885b78/codex-rs/app-server/src/codex_message_processor.rs (L6477-L6487)
- Expose `CodexThread::config()` so app-server can pass the live config
into memory startup at turn time.
- Add a six-hour successful-run cooldown for global phase-2
consolidation via `SkippedCooldown`:
d4a6885b78/codex-rs/state/src/runtime/memories.rs (L963-L966)
- Reduce memory startup defaults to at most 2 rollouts over 10 days:
d4a6885b78/codex-rs/config/src/types.rs (L31-L34)
## Verification
Updated the memory runtime coverage around phase-2 reclaim behavior,
including `phase2_global_lock_respects_success_cooldown`.

## Why
`ThreadConfigSnapshot` is used by app-server and thread metadata code as
a stable view of active runtime settings. Keeping both `sandbox_policy`
and `permission_profile` in the snapshot duplicates permission state and
makes it possible for the legacy projection to drift from the canonical
profile.
The legacy `sandbox` value is still needed at app-server compatibility
boundaries, so this PR derives it on demand from the snapshot profile
and cwd instead of storing it.
## What Changed
- Removes `ThreadConfigSnapshot.sandbox_policy`.
- Adds `ThreadConfigSnapshot::sandbox_policy()` as a compatibility
projection from `permission_profile` plus `cwd`.
- Updates app-server response/metadata code and tests to call the
projection only where legacy fields still exist.
- Keeps snapshot construction profile-only so split filesystem rules,
disabled enforcement, and external enforcement remain represented by the
canonical profile.
## Verification
- `cargo test -p codex-app-server

- `cargo test -p codex-core

## Why
`SessionConfiguredEvent` is the internal event that tells clients what
permissions are active for a session. Emitting both `sandbox_policy` and
`permission_profile` leaves two possible authorities and forces every
consumer to decide which one to honor. At this point in the migration,
the profile is expressive enough to represent managed, disabled, and
external sandbox enforcement, so the internal event can be profile-only.
The wire compatibility concern is older serialized events or rollout
data that only contain `sandbox_policy`; those still need to
deserialize.
## What Changed
- Removes `sandbox_policy` from `SessionConfiguredEvent` and makes
`permission_profile` required.
- Adds custom deserialization so old payloads with only `sandbox_policy`
are upgraded to a cwd-anchored `PermissionProfile`.
- Updates core event emission and TUI session handling to sync
permissions from the profile directly.
- Updates app-server response construction to derive the legacy
`sandbox` response field from the active thread snapshot instead of from
`SessionConfiguredEvent`.
- Updates yolo-mode display logic to treat both
`PermissionProfile::Disabled` and managed unrestricted filesystem plus
enabled network as full-access, while still preserving the distinction
between no sandbox and external sandboxing.

## Why
The remaining review, interrupt, fuzzy search, feedback, and git-diff
handlers still had local send-error branches that obscured otherwise
simple request handling. This final slice flattens those handlers
without changing the public protocol behavior.
## What Changed
- Streamlined review start, turn interrupt, fuzzy search session,
feedback upload, and git diff handlers in
`codex-rs/app-server/src/codex_message_processor.rs`.
- Converted validation and upload failures into returned JSON-RPC errors
where that avoids nested `send_error`/`return` blocks.
- Left unrelated sandbox setup and notification code untouched.
## Verification
- `cargo check -p codex-app-server`
- `cargo test -p codex-app-server --test all v2::review --
--test-threads=1`
## Why
Turn and realtime handlers had nested validation and send-error branches
that made the request path longer than the behavior warranted. This
slice keeps the same request semantics while letting the handlers return
errors from the failing step.
## What Changed
- Streamlined turn start, injected item, and turn steer request handling
in `codex-rs/app-server/src/codex_message_processor.rs`.
- Applied the same result-returning shape to realtime session response
handlers.
- Preserved existing request validation and thread-manager interactions.

--test-threads=1`
- `cargo test -p codex-app-server --test all v2::thread_inject_items --
--test-threads=1`
## Why
Thread resume and fork had some of the deepest error-handling
indentation in this area because helpers emitted request errors
directly. Returning those failures gives the handlers a single request
boundary while preserving the async pending-resume behavior.
## What Changed
- Converted thread resume helpers in
`codex-rs/app-server/src/codex_message_processor.rs` to return `Result`
values for validation and view loading failures.
- Applied the same pattern to thread fork request handling.
- Simplified pending resume error construction by using the shared
JSON-RPC error helpers.
## Verification
- `cargo check -p codex-app-server`
- `cargo test -p codex-app-server --test all v2::thread_resume --
--test-threads=1`
- `cargo test -p codex-app-server --test all v2::thread_fork --
--test-threads=1`
## Why
The thread read/list handlers mostly assemble views, but their error
handling was interleaved with response emission. Returning view-building
errors from the helper path keeps those handlers focused on data
assembly.
## What Changed
- Added a small mapper for `ThreadReadViewError` to JSON-RPC errors in
`codex-rs/app-server/src/codex_message_processor.rs`.
- Streamlined thread list, loaded-thread, read, turn-list, and summary
handlers to produce result values for the request boundary.
- Kept the existing invalid-request vs internal-error distinctions for
missing or unreadable thread data.
## Verification
- `cargo check -p codex-app-server`
- `cargo test -p codex-app-server --test all conversation_summary --
--test-threads=1`
## Why
Thread mutation handlers had many short error branches whose only job
was to emit a JSON-RPC error and stop. This slice keeps those errors
visible, but lets each handler build a result and return early from
validation helpers instead of nesting the main path.
## What Changed
- Streamlined thread archive/unarchive, rename, memory, metadata,
rollback, compact, background terminal, shell, and guardian handlers in
`codex-rs/app-server/src/codex_message_processor.rs`.
- Reused shared JSON-RPC error constructors in
`codex-rs/app-server/src/bespoke_event_handling.rs` for rollback-related
request failures.
- Preserved direct `send_error` calls where they remain the simplest
boundary for pending async event responses.
## Verification
- `cargo check -p codex-app-server`
- `cargo test -p codex-app-server --test all v2::thread_rollback --
--test-threads=1`
## Why
The thread start handler mixed request validation, thread construction,
dynamic-tool validation, and JSON-RPC error emission in one nested flow.
Returning request errors from the helper path makes the successful setup
path easier to follow.
## What Changed
- Reworked `thread/start` handling in
`codex-rs/app-server/src/codex_message_processor.rs` so helper methods
return `Result` and the handler emits one result.
- Moved dynamic-tool validation failures into returned JSON-RPC errors
instead of local `send_error` branches.
- Preserved the existing thread creation and task-spawning behavior.
## Verification
- `cargo check -p codex-app-server`
- `cargo test -p codex-app-server --test all v2::dynamic_tools --
--test-threads=1`
- `cargo test -p codex-app-server --test all v2::turn_start --
--test-threads=1`
## Why
The experimental `PermissionProfile` API had both `:cwd` and
`:project_roots` special filesystem paths, which made the permission
root ambiguous. This PR removes the unstable `current_working_directory`
special path before the permissions API is stabilized, so callers use
`:project_roots` for symbolic project-root access.
## What changed
- Removes `FileSystemSpecialPath::CurrentWorkingDirectory` from protocol
and app-server protocol models, plus regenerated app-server
JSON/TypeScript schemas.
- Replaces internal `:cwd` permission entries with `:project_roots`
entries.
- Keeps the existing cwd-update behavior for legacy-shaped
workspace-write profiles, while removing the deleted
`CurrentWorkingDirectory` case from that compatibility path.
- Keeps `PermissionProfile::workspace_write()` as the reusable symbolic
workspace-write helper, with docs noting that `:project_roots` entries
resolve at enforcement time.
- Updates app-server docs/examples and approval UI labeling to stop
advertising `:cwd` as a permission token.
## Compatibility
Persisted rollout items may contain the old
`{"kind":"current_working_directory"}` tag from earlier experimental
`permissionProfile` snapshots. This PR keeps that tag as a
deserialize-only alias for `ProjectRoots { subpath: None }`, while
continuing to serialize only the new `project_roots` tag.
## Follow-up
This PR intentionally does not introduce an explicit project-root set on
`SessionConfiguration` or runtime sandbox resolution. Today, the
resolver still uses the active cwd as the single implicit project root.
A follow-up should model project roots separately from tool cwd so
`:project_roots` entries can resolve against the configured project
roots, and resolve to no entries when there are no project roots.

## Why
Account login/logout and command exec handlers were doing local error
sends in the middle of each handler. That made these request flows
branch heavily even though most of the logic is validate, perform the
operation, and return the response.
## What Changed
- Converted ChatGPT/API-key login, login cancel, logout, rate-limit, and
add-credit handlers in
`codex-rs/app-server/src/codex_message_processor.rs` to compute `Result`
values and send them once at the request boundary.
- Applied the same shape to command exec start/write/resize/terminate
handlers.
- Kept side-effect notifications in the same places after successful
request handling.
