## Why
The memories MCP `search` tool only accepts a single substring today,
which makes it hard for clients to express combined queries or explain
why a line matched. This change adds the richer search shape needed for
the next client iteration while keeping the legacy single-`query` call
working.
## What changed
- accept either the legacy `query` field or a new `queries` array, plus
`match_mode: any|all`
- teach the local memories backend to evaluate multi-query line matches
and return `matched_queries` on each hit
- update the MCP input/output schema and add coverage for parser
behavior, ordering, pagination, case sensitivity, and match modes
## Testing
- added unit coverage in `memories/mcp/src/local_tests.rs` and
`memories/mcp/src/server.rs`
## Why
The paginated memories MCP `search` tool still returned only the
matching line text, which made it harder for clients to present useful
search results or decide whether they needed to follow up with a
separate `read` call. Adding a small amount of surrounding context makes
individual hits much more usable while keeping the search response
deterministic and line-addressable.
## What changed
- add an optional `context_lines` search argument and thread it through
the MCP server into the local memories backend
- change search matches to return the matched `line_number` plus a
`start_line_number` and multi-line `content` block for the requested
context window
- update the search tool schema and description to document the new
request/response shape
- extend the local backend tests to cover zero-context matches,
contextual results, pagination, and invalid cursors that point past the
end of the result set
## Testing
- Added targeted unit coverage in `memories/mcp/src/local_tests.rs`
- GitHub Actions are running for the branch

## Why
The memories MCP `search` tool previously stopped once it hit
`max_results`, so callers could tell there were more matches via
`truncated` but had no way to fetch the rest of the result set. That
made large searches awkward for clients that need to keep paging through
a stable, deterministic view of the matches.
## What changed
- add an optional `cursor` field to `SearchMemoriesRequest` / tool input
and return `next_cursor` in `SearchMemoriesResponse`
- update the MCP schemas and tool wiring so clients can request
subsequent pages explicitly
- change the local memories backend to collect and sort the full scoped
match list, then slice the requested page and reject invalid cursors
- add unit coverage for paginated search results and invalid cursor
handling in `memories/mcp/src/local_tests.rs`
## Testing
- Added targeted unit coverage in `memories/mcp/src/local_tests.rs`
- GitHub Actions are running for the branch
## Why
The memories MCP `list` tool should behave like a directory listing, not
a recursive tree walk. Recursive results make pagination harder to
reason about, return unexpectedly deep paths for scoped requests, and no
longer match the intended tool contract.
## What Changed
- Changed the local memories backend so `list` returns only the
immediate children of the requested path.
- Preserved file-scoped requests by returning the file itself, and
missing paths by returning an empty result.
- Updated cursor handling to paginate over the shallow sibling set and
reject cursors past the available results.
- Updated the MCP tool description to say it lists immediate files and
directories under a path.
- Reworked the local backend tests to cover shallow top-level listing,
shallow scoped listing, sibling ordering, and pagination.
## Testing
- `cargo test -p codex-memories-mcp`
## Why
Large memories trees do not fit well into a single MCP `list` response.
This change makes the memories MCP server page `list` results so callers
can continue walking the tree without overfetching or relying on
ambiguous truncation.
## What changed
- add an optional `cursor` input to the memories MCP `list` API and
return `next_cursor` alongside `truncated` in the response
- paginate recursive local-memory traversal while preserving
lexicographic path order across directories
- reject malformed and out-of-range cursors as invalid MCP requests
- update the server/schema wiring and add coverage for pagination,
ordering, and cursor validation in `memories/mcp/src/local_tests.rs`
## Testing
- `cargo test -p codex-memories-mcp`
## Why
The memories MCP `read` tool already supports `line_offset`, but it
cannot return a bounded line range. That makes it awkward to page
through large memory files or request a small slice without relying on
token truncation.
## What changed
- add an optional `max_lines` parameter to the memories MCP `read` tool
schema and request parsing
- cap local backend reads to the requested number of lines before token
truncation
- treat `max_lines = 0` as an invalid request and surface it as
`invalid_params`
- add backend tests for bounded reads and invalid line request
validation
## Testing
- added coverage in `memories/mcp/src/local_tests.rs` for `max_lines`
reads and invalid `max_lines` / `line_offset` requests
## Why
Memory clients sometimes need to continue reading a file from a known
line instead of starting over from the top. Adding a line offset to the
`read` MCP keeps that resume logic simple and avoids re-reading
already-consumed content.
## What changed
- Added an optional `line_offset` argument to the memory `read` tool,
defaulting to `1`.
- Read content starting at the requested 1-indexed line before token
truncation, and return `start_line_number` in the response.
- Treat invalid offsets as invalid params errors and cover the new
behavior in `codex-rs/memories/mcp/src/local_tests.rs`.
## Testing
- Added unit tests for reading from a non-default starting line.
- Added unit tests for rejecting `0` and past-end line offsets.
## Why
This adds the `remote_compaction_v2` client path so remote compaction
can run through the normal Responses stream and install a
`context_compaction` item that trigger a compaction.
The goal is to migrate some of the compaction logic on the client side
We keeps the v2 transport behind a feature flag while letting follow-up
requests reuse the compacted context instead of falling back to the
legacy compaction item shape.
## What changed
- add `ResponseItem::ContextCompaction` and refresh the generated
app-server / schema / TypeScript fixtures that expose response items on
the wire
- add `core/src/compact_remote_v2.rs` to send compaction through the
standard streamed Responses client, require exactly one
`context_compaction` output item, and install that item into compacted
history
- route manual compact and auto-compaction through the v2 path when
`remote_compaction_v2` is enabled, while keeping the existing remote
compaction path as the fallback
- preserve the new item type across history retention, follow-up request
construction, telemetry, rollout persistence, and rollout-trace
normalization
- add targeted coverage for the feature flag, `context_compaction`
serialization, rollout-trace normalization, and remote-compaction
follow-up behavior
## Verification
- added protocol tests for `context_compaction`
serialization/deserialization in `protocol/src/models.rs`
- added rollout-trace coverage for `context_compaction` normalization in
`rollout-trace/src/reducer/conversation_tests.rs`
- added remote compaction integration coverage for v2 follow-up reuse
and mixed compaction output streams in
`core/tests/suite/compact_remote.rs`

## Why
`multi_agent_v2` usage hints sometimes need to reference resolved config
values such as the effective thread limit. Those values only exist after
config layering, defaulting, and feature materialization, so the raw
TOML alone was not enough to render them.
## What changed
- allow
`features.multi_agent_v2.{usage_hint_text,root_agent_usage_hint_text,subagent_usage_hint_text}`
to use `{{ ... }}` placeholders backed by the materialized effective
config
- fail config loading with a targeted error when a referenced
placeholder does not exist or does not resolve to a scalar value
- move resolved-config materialization into a shared helper so config
interpolation and config-lock export/replay both serialize the same
resolved feature, memory, and agent settings
## Example
```
[features.multi_agent_v2]
enabled = true
usage_hint_text = "lorem {{ features.multi_agent_v2.max_concurrent_threads_per_session }} ipsum"
```
gets rendered as
```
"description": String("... \lorem 4 ipsum"),
```
## Why
`McpToolCall` was still an app-server item synthesized from deprecated
legacy begin/end events. Recent item migrations moved this ownership
into core `TurnItem`s, so MCP tool calls now follow the same canonical
lifecycle and leave legacy events as compatibility fanout.
Keeping the core item close to the v2 `ThreadItem::McpToolCall` shape
also avoids spreading MCP result semantics across app-server conversion
code. Core now owns whether a completed call is `completed` or `failed`,
and whether the payload is a tool result or an error.
## What changed
- Added core `TurnItem::McpToolCall` with flattened `server`, `tool`,
`arguments`, `status`, `result`, and `error` fields.
- Updated MCP tool call emitters, including MCP resource tools, to emit
`ItemStarted`/`ItemCompleted` around directly constructed core MCP
items.
- Updated app-server v2 conversion to project the core MCP item into
`ThreadItem::McpToolCall` without deriving status or splitting `Result`
locally.
- Ignored live deprecated MCP legacy fanout in app-server v2 to avoid
duplicate item notifications, while keeping thread history replay on the
legacy event path.
## Verification
- `cargo test -p codex-protocol`
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-core --lib mcp_tool_call`
- `cargo check -p codex-app-server`
- `cargo test -p codex-app-server
mcp_tool_call_completion_notification_contains_truncated_large_result`
## Why
App-server request handling had response sending spread across many
individual handlers, which made it harder to see which requests return
payloads, which methods send their own delayed response, and which
branches emit notifications after a response.
## What changed
- Centralized normal `ClientResponsePayload` sending in the dispatch
path.
- Kept explicit-response methods explicit where they need custom
ordering or delayed delivery.
- Removed forward-only handler wrappers and immediate `async { ...
}.await` bodies where they were not needed.
- Moved branch-specific post-response notifications into the branches
that own the response ordering.
- Replaced unreachable delegated request-family error arms with explicit
`unreachable!` cases.
## Verification
- `cargo check -p codex-app-server`
- `cargo test -p codex-app-server thread_goal`
- `just fix -p codex-app-server`
## Summary
We should not check local-only docs or planning specs into this
repository. Keeping those files here duplicates the canonical Codex
documentation surface and makes transient implementation notes look like
supported docs.
This PR removes the local-only docs/spec files from `docs/` and trims
`docs/config.md` back to links for the maintained configuration
documentation on developers.openai.com.
## Why
The automated issue labeler needs more precise area labels for newly
opened GitHub issues so triage can distinguish new Codex app and agent
feature surfaces without falling back to broad labels.
## What Changed
- Added labeler prompt entries for `computer-use`, `browser`, `memory`,
`imagen`, `remote`, `performance`, `automations`, and `pets` in
`.github/workflows/issue-labeler.yml`.
- Updated the agent-area guidance so `memory` is used for agentic memory
storage/retrieval and `performance` is used for slow behavior, high
memory utilization, and leaks.
- Expanded the fallback `agent` guidance so Codex prefers the new
specific labels when applicable.
## Verification
- Parsed `.github/workflows/issue-labeler.yml` with `yq e '.'`.
- Ran `git diff --check` for the workflow change.
## Why
We saw Responses websocket sessions recover only after a long quiet
period when the server had already logged the websocket as disconnected.
The normal connect path is already bounded by
`websocket_connect_timeout_ms`, but the first request send on an
established websocket reused only the receive-side idle timeout after
the write completed. If the socket write/pump stalls, the client can sit
in `ws_stream.send(...)` without reaching the existing receive timeout.
Tool suggest still misfires when model needs tool_search, updating the
prompts to further disambiguate it:
- [x] rename it from `tool_suggest` to `request_plugin_install`
- [x] rephrase "suggestion" to "install" in the tool descriptions.
- [x] disambiguate "the tool" vs "the plugin/connector".
Tested with the Codex App and verified it still works.
## Summary
Bound TUI startup terminal response probes so unsupported terminals
cannot stall startup for multiple seconds.
This replaces the Unix startup uses of crossterm's blocking response
probes with short `/dev/tty` probes that use nonblocking reads and
`poll` with a 100ms timeout. It covers the initial cursor-position
query, keyboard enhancement support detection, and OSC 10/11
default-color detection. The default-color probe uses one shared
deadline for foreground and background instead of allowing two
independent full waits.
The diagnostic mode/trace env vars from the investigation branch are
intentionally not included. The shipped behavior is simply bounded
probing by default, while non-Unix keeps the existing crossterm fallback
path.
## Details
- Add a private `terminal_probe` module for bounded Unix terminal probes
and response parsers.
- Let `custom_terminal::Terminal` accept a caller-provided initial
cursor position so startup can compute it before constructing the
terminal.
- Use bounded cursor, keyboard enhancement, and default-color probes on
Unix startup.
- Preserve default-color cache behavior so a failed attempted query does
not retry forever.
## Validation
- `cd codex-rs && just fmt`
- `cd codex-rs && cargo test -p codex-tui terminal_probe`
- `cd codex-rs && just fix -p codex-tui`
- `cd codex-rs && just argument-comment-lint`
- `git diff --check`
- `git diff --cached --check`
`cd codex-rs && cargo test -p codex-tui` still aborts on the
pre-existing local stack overflow in
`app::tests::discard_side_thread_keeps_local_state_when_server_close_fails`;
I reproduced that same focused failure on `main` before this PR work, so
it is not introduced by this change.
Manual validation in the VM showed the original crossterm path taking
about 2s per unanswered probe, while bounded probing returned in about
100ms per probe.

https://linear.app/openai/issue/SE-6311/login-fails-for-experian-users-behind-tls-inspecting-proxy
## Summary
- When a custom CA bundle is configured, force the shared `codex-client`
reqwest builder onto rustls before registering custom roots.
- Add the `rustls-tls-native-roots` reqwest feature so the rustls client
preserves native roots plus the enterprise CA bundle.
- Add subprocess TLS coverage for both a direct local TLS 1.3 server and
a hermetic local CONNECT TLS-intercepting proxy that forwards a
token-exchange-shaped POST to a local origin.
## Plain-language explanation
Experian users are behind a TLS-inspecting proxy, so the login token
exchange needs to trust the enterprise CA bundle from
`CODEX_CA_CERTIFICATE` or `SSL_CERT_FILE`. Before this change, that
custom-CA branch still used reqwest default TLS selection, which could
fail in the proxy environment. Now, only when a custom CA is configured,
Codex selects rustls first and then adds the custom CA roots, matching
the validated behavior from the Experian test build while leaving normal
system-root clients unchanged.
The new regression test recreates the enterprise-proxy shape locally:
the probe client sends an HTTPS `POST /oauth/token` through an explicit
HTTP CONNECT proxy, the proxy presents a leaf certificate signed by a
runtime-generated test CA, decrypts the request, forwards it to a local
origin, and relays the `ok` response back.
## Scope note
- The actual production fix is the first commit: `8368119282 Fix custom
CA reqwest clients to use rustls`.
- The second commit is integration-test coverage only. It generates all
test CA and localhost certificate material at runtime.

## Why
#20585 moved the Windows Bazel test job to the cross-compile path, but
the Windows Bazel clippy and verify-release-build jobs were still using
the native Windows/MSVC-host fallback. Those two jobs became the slowest
Windows PR legs, even though both are build-only signal and do not need
to execute the resulting binaries.
## What Changed
- Switches the Windows Bazel clippy job from
`--windows-msvc-host-platform` to `--windows-cross-compile`, so clippy
build actions use Linux RBE while still targeting
`x86_64-pc-windows-gnullvm`.
- Switches the Windows Bazel verify-release-build job to
`--windows-cross-compile` as well. This job only compiles
`cfg(not(debug_assertions))` Rust code under `fastbuild`, so it does not
need a native Windows build host.
- Keeps the old `--skip_incompatible_explicit_targets` behavior only for
fork/community PRs without `BUILDBUDDY_API_KEY`, where `run-bazel-ci.sh`
falls back to the local Windows MSVC-host shape.
- Adds `--windows-cross-compile` support to
`.github/scripts/run-bazel-query-ci.sh`, so target-discovery queries
select the same `ci-windows-cross` config as the subsequent build.
- Threads that option through `scripts/list-bazel-clippy-targets.sh` so
the Windows clippy job discovers targets under the same platform shape
as the subsequent clippy build.
## Verification
Local checks:
```shell
bash -n .github/scripts/run-bazel-query-ci.sh
bash -n scripts/list-bazel-clippy-targets.sh
ruby -e 'require "yaml"; YAML.load_file(".github/workflows/bazel.yml"); puts "ok"'
RUNNER_OS=Linux ./scripts/list-bazel-clippy-targets.sh | grep -c -- '-windows-cross-bin$'
RUNNER_OS=Windows ./scripts/list-bazel-clippy-targets.sh --windows-cross-compile | grep -c -- '-windows-cross-bin$'
```
The Linux target-list check reported `0` Windows-cross internal test
binaries, while the Windows cross target-list check reported `47`,
preserving the test-code clippy coverage shape from the existing Windows
job.
## Status
This is the Bazel PR-CI cross-compilation follow-up to #20485. It is
intentionally split from the Cargo/cargo-xwin release-build PoC so
#20485 can stay as the historical release-build exploration. The
unrelated async-utils test cleanup has been moved to #20686, so this PR
is focused on the Windows Bazel CI path.
The intended tradeoff is now explicit in `.github/workflows/bazel.yml`:
pull requests get the fast Windows cross-compiled Bazel test leg, while
post-merge pushes to `main` run both that fast cross leg and a fully
native Windows Bazel test leg. The native main-only job keeps full
V8/code-mode coverage and gets a 40-minute timeout because it is less
latency-sensitive than PR CI. All other Bazel jobs remain at 30 minutes.
## Why
Windows Bazel PR CI currently does the expensive part of the build on
Windows. A native Windows Bazel test job on `main` completed in about
28m12s, leaving very little headroom under the 30-minute job timeout and
making Windows the slowest PR signal.
#20485 showed that Windows cross-compilation can be materially faster
for Cargo release builds, but PR CI needs Bazel because Bazel owns our
test sharding, flaky-test retries, and integration-test layout. This PR
applies the same high-level shape we already use for macOS Bazel CI:
compile with remote Linux execution, then run platform-specific tests on
the platform runner.
The compromise is deliberately signal-aware: code-mode/V8 changes are
rare enough that PR CI can accept losing the direct V8/code-mode
smoke-test signal temporarily, while `main` still runs the native
Windows job post-merge to catch that class of regression. A follow-up PR
should investigate making the cross-built Windows gnullvm V8 archive
pass the direct V8/code-mode tests so this tradeoff can eventually go
away.
## What Changed
- Adds a `ci-windows-cross` Bazel config that targets
`x86_64-pc-windows-gnullvm`, uses Linux RBE for build actions, and keeps
`TestRunner` actions local on the Windows runner.
- Adds explicit Windows platform definitions for
`windows_x86_64_gnullvm`, `windows_x86_64_msvc`, and a bridge toolchain
that lets gnullvm test targets execute under the Windows MSVC host
platform.
- Updates the Windows Bazel PR test leg to opt into the cross-compile
path via `--windows-cross-compile` and `--remote-download-toplevel`.
- Adds a `test-windows-native-main` job that runs only for `push` events
on `refs/heads/main`, uses the native Windows Bazel path, includes
V8/code-mode smoke tests, and has `timeout-minutes: 40`.
- Keeps fork/community PRs without `BUILDBUDDY_API_KEY` on the previous
local Windows MSVC-host fallback, including
`--host_platform=//:local_windows_msvc` and `--jobs=8`.
- Preserves the existing integration-test shape on non-gnullvm
platforms, while generating Windows-cross wrapper targets only for
`windows_gnullvm`.
- Resolves `CARGO_BIN_EXE_*` values from runfiles at test runtime,
avoiding hard-coded Cargo paths and duplicate test runfiles.
- Extends the V8 Bazel patches enough for the
`x86_64-pc-windows-gnullvm` target and Linux remote execution path.
- Makes the Windows sandbox test cwd derive from `INSTA_WORKSPACE_ROOT`
at runtime when Bazel provides it, because cross-compiled binaries may
contain Linux compile-time paths.
- Keeps the direct V8/code-mode unit smoke tests out of the Windows
cross PR path for now while native Windows CI continues to cover them
post-merge.
## Command Shape
The fast Windows PR test leg invokes the normal Bazel CI wrapper like
this:
```shell
./.github/scripts/run-bazel-ci.sh \
--print-failed-action-summary \
--print-failed-test-logs \
--windows-cross-compile \
--remote-download-toplevel \
-- \
test \
--test_tag_filters=-argument-comment-lint \
--test_verbose_timeout_warnings \
--build_metadata=COMMIT_SHA=${GITHUB_SHA} \
-- \
//... \
-//third_party/v8:all \
-//codex-rs/code-mode:code-mode-unit-tests \
-//codex-rs/v8-poc:v8-poc-unit-tests
```
With the BuildBuddy secret available on Windows, the wrapper selects
`--config=ci-windows-cross` and appends the important Windows-cross
overrides after rc expansion:
```shell
--host_platform=//:rbe
--shell_executable=/bin/bash
--action_env=PATH=/usr/bin:/bin
--host_action_env=PATH=/usr/bin:/bin
--test_env=PATH=${CODEX_BAZEL_WINDOWS_PATH}
```
The native post-merge Windows job intentionally omits
`--windows-cross-compile` and does not exclude the V8/code-mode unit
targets:
```shell
./.github/scripts/run-bazel-ci.sh \
--print-failed-action-summary \
--print-failed-test-logs \
-- \
test \
--test_tag_filters=-argument-comment-lint \
--test_verbose_timeout_warnings \
--build_metadata=COMMIT_SHA=${GITHUB_SHA} \
--build_metadata=TAG_windows_native_main=true \
-- \
//... \
-//third_party/v8:all
```
## Research Notes
The existing macOS Bazel CI config already uses the model we want here:
build actions run remotely with `--strategy=remote`, but `TestRunner`
actions execute on the macOS runner. This PR mirrors that pattern for
Windows with `--strategy=TestRunner=local`.
The important Bazel detail is that `rules_rs` is already targeting
`x86_64-pc-windows-gnullvm` for Windows Bazel PR tests. This PR changes
where the build actions execute; it does not switch the Bazel PR test
target to Cargo, `cargo-nextest`, or the MSVC release target.
Cargo release builds differ from this Bazel path for V8: the normal
Windows Cargo release target is MSVC, and `rusty_v8` publishes prebuilt
Windows MSVC `.lib.gz` archives. The Bazel PR path targets
`windows-gnullvm`; `rusty_v8` does not publish a prebuilt Windows
GNU/gnullvm archive, so this PR builds that archive in-tree. That
Linux-RBE-built gnullvm archive currently crashes in direct V8/code-mode
smoke tests, which is why the workflow keeps native Windows coverage on
`main`.
The less obvious Bazel detail is test wrapper selection. Bazel chooses
the Windows test wrapper (`tw.exe`) from the test action execution
platform, not merely from the Rust target triple. The outer
`workspace_root_test` therefore declares the default test toolchain and
uses the bridge toolchain above so the test action executes on Windows
while its inner Rust binary is built for gnullvm.
The V8 investigation exposed a Windows-client gotcha: even when an
action execution platform is Linux RBE, Bazel can still derive the
genrule shell path from the Windows client. That produced remote
commands trying to run `C:\Program Files\Git\usr\bin\bash.exe` on Linux
workers. The wrapper now passes `--shell_executable=/bin/bash` with
`--host_platform=//:rbe` for the Windows cross path.
The same Windows-client/Linux-RBE boundary also affected
`third_party/v8:binding_cc`: a multiline genrule command can carry CRLF
line endings into Linux remote bash, which failed as `$'\r'`. That
genrule now keeps the `sed` command on one physical shell line while
using an explicit Starlark join so the shell arguments stay readable.
## Verification
Local checks included:
```shell
bash -n .github/scripts/run-bazel-ci.sh
bash -n workspace_root_test_launcher.sh.tpl
ruby -e "require %q{yaml}; YAML.load_file(%q{.github/workflows/bazel.yml}); puts %q{ok}"
RUNNER_OS=Linux ./scripts/list-bazel-clippy-targets.sh
RUNNER_OS=Windows ./scripts/list-bazel-clippy-targets.sh
RUNNER_OS=Linux ./tools/argument-comment-lint/list-bazel-targets.sh
RUNNER_OS=Windows ./tools/argument-comment-lint/list-bazel-targets.sh
```
The Linux clippy and argument-comment target lists contain zero
`*-windows-cross-bin` labels, while the Windows lists still include 47
Windows-cross internal test binaries.
CI evidence:
- Baseline native Windows Bazel test on `main`: success in about 28m12s,
https://github.com/openai/codex/actions/runs/25206257208/job/73907325959
- Green Windows-cross Bazel run on the split PR before adding the
main-only native leg: Windows test 9m16s, Windows release verify 5m10s,
Windows clippy 4m43s,
https://github.com/openai/codex/actions/runs/25231890068
- The latest SHA adds the explicit PR-vs-main tradeoff in `bazel.yml`;
CI is rerunning on that focused diff.
## Follow-Up
A subsequent PR should investigate making a cross-built Windows binary
work with V8/code-mode enabled. Likely options are either making the
Linux-RBE-built `windows-gnullvm` V8 archive correct at runtime, or
evaluating whether a Bazel MSVC target/toolchain can reuse the same
prebuilt MSVC `rusty_v8` archive shape that Cargo release builds already
use.
## Why
The model needs a way to see which environments are available during a
multi-environment turn without changing the legacy single-environment
prompt surface or pulling replay/persistence changes into the same
review.
## Stack
1. https://github.com/openai/codex/pull/20646 - `EnvironmentContext`
rendering for selected environments (this PR)
2. https://github.com/openai/codex/pull/20669 - selected-environment
ownership and tool config prep
3. https://github.com/openai/codex/pull/20647 - process-tool
`environment_id` routing
## What Changed
- extend `environment_context` so multi-environment turns render an
`<environments>` block with the selected environment ids and cwd values
- keep zero- and single-environment turns on the existing cwd-only
render path
- keep replay and persistence paths on the legacy surface for now so
this PR stays scoped to live prompt rendering
- add focused coverage in
`codex-rs/core/src/context/environment_context_tests.rs`

# Why
When a user interrupts a turn while a hook is still running, the normal
turn status is cleared but the separate live hook row can remain visible
as `Running` because the TUI may never receive a matching
`HookCompleted` event before cancellation. Once the turn itself is
finalized, that turn-scoped live state should not remain on screen.
# What
- clear any still-live `active_hook_cell` during turn finalization
- add a regression snapshot covering an interrupted turn with a visible
`PreToolUse` hook row
# Testing
- `cargo test -p codex-tui interrupted_turn_clears_visible_running_hook`
- attempted `cargo test -p codex-tui` (currently aborts on unrelated
existing stack overflow in
`app::tests::discard_side_thread_removes_agent_navigation_entry`)
