## Why
`multi_agents_v2` is meant to be independently gated from the older
`collab` feature. The tool registry still treated the
collaboration-style agent tools as `collab`-only, so enabling
`multi_agents_v2` without `collab` omitted the v2 agent tools. Review
and guardian sub-sessions also need to keep agent spawning disabled even
when the outer session has `multi_agents_v2` enabled.
## What changed
- Include the collab-backed agent tools when either `multi_agents_v2` or
`collab` is enabled.
- Explicitly disable `multi_agents_v2` for review and guardian review
sub-sessions, matching the existing `spawn_csv` and `collab`
restrictions.
- Add a registry test that enables `multi_agents_v2`, disables `collab`,
and verifies the v2 agent tools are present while legacy `send_input`
and `resume_agent` remain hidden.
## Testing
- Added
`test_build_specs_multi_agent_v2_does_not_require_collab_feature`.
## 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
#20271 increased the `90`-minute timeout in `rust-release.yml`, but it
did not update the reusable Windows workflow in
`rust-release-windows.yml`. As a result, the Windows release compile
jobs were still capped at `60` minutes and the `windows-x64` primary
build could continue timing out.
We are keeping the existing `90`-minute timeout in `rust-release.yml`.
That increase was still directionally correct because the top-level
release build benefits from extra headroom; the mistake was assuming it
also covered the reusable Windows jobs.
## What Changed
- increase the reusable Windows release workflow timeouts in
`rust-release-windows.yml` from `60` minutes to `90` minutes
- update the comment in `rust-release.yml` so it no longer implies that
the top-level timeout covers the Windows reusable jobs
## 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.

## Summary
- [x] Move the allowlist out of core crate
- [x] Add Teams, SharePoint, Outlook Email, and Outlook Calendar to the
tool_suggest discoverable plugin allowlist
- [x] Add focused coverage for Microsoft curated plugin discovery
## Testing
- just fmt
- cargo test -p codex-core-plugins
- cargo test -p codex-core

## Why
Reused Guardian review trunks can still have older child-turn events
queued when a later review starts. The review waiter currently accepts
the first terminal event it sees from the shared child session, so a
stale `TurnComplete` can be attributed to the new review. That produces
impossible analytics combinations such as non-null TTFT with sub-10 ms
completion latency and zero token deltas on `trunk_reused` reviews.
## What changed
- Preserve the child turn id returned by the Guardian review
`Op::UserTurn` submission.
- Restrict Guardian review waiting to events correlated with that
submitted child turn.
- Restrict timeout/abort draining to terminal events for the same child
turn.
- Add regression coverage for stale prior-turn completions, stale
prior-turn errors, and interrupt draining in
`codex-rs/core/src/guardian/review_session.rs`.
## Verification
- `cargo test -p codex-core guardian::review_session::tests::`
- `cargo clippy -p codex-core --tests -- -D warnings`
## Why
Fixes#20264.
Side conversations are an ephemeral layer on top of the main chat.
Pressing `Ctrl+D` from an empty side-chat composer should unwind back to
the parent thread, matching the existing side-return behavior, instead
of falling through to the global quit shortcut and exiting Codex.
## What changed
The side-return shortcut matcher now treats `Ctrl+D` the same way it
already treats `Esc` and `Ctrl+C`. Because app-level side-return
handling runs before the chat widget's global quit handling, this
returns from `/side` while preserving normal `Ctrl+D` quit behavior
outside side conversations.
The existing shortcut coverage was updated to include lowercase and
uppercase `Ctrl+D` key events.
## Verification
- `cargo test -p codex-tui
side_return_shortcuts_match_esc_ctrl_c_and_ctrl_d`
- `cargo test -p codex-tui` starts successfully and the new shortcut
test passes, but the broader suite later aborts in the unrelated
existing test
`app::tests::attach_live_thread_for_selection_rejects_unmaterialized_fallback_threads`
with a stack overflow.
Summary:
- Return from external agent import before session history import
finishes
- Run session import work in the background and emit the existing
completion notification when it is done
- Serialize session imports so duplicate requests do not create
duplicate imported threads
Verification:
- cargo test -p codex-app-server external_agent_config_
- cargo test -p codex-external-agent-sessions
- just fix -p codex-app-server
- just fix -p codex-external-agent-sessions
- git diff --check
## Summary
- Support Claude Code `ai-title` / `aiTitle` records when detecting and
importing external agent sessions.
- Preserve existing `custom-title` / `customTitle` precedence; only fall
back to `aiTitle` when no custom title is present.
- Add coverage for both detection and import title selection, including
the custom-title-over-ai-title case.
## Testing
- `cargo test -p codex-external-agent-sessions`
- `just fix -p codex-external-agent-sessions`
## Why
We need a way to list the available hooks to expose via the TUI and App
so users can view and manage their hooks
## What
- Adds `hooks/list` for one or more `cwd` values that returns discovered
hook metadata

## 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`
