• Allow clients not to send summary as an option (#12950)

  Summary is a required parameter on UserTurn. Ideally we'd like the core
  to decide the appropriate summary level.
  
  Make the summary optional and don't send it when not needed.

• core: bundle settings diff updates into one dev/user envelope (#12417)

  ## Summary
  - bundle contextual prompt injection into at most one developer message
  plus one contextual user message in both:
    - per-turn settings updates
    - initial context insertion
  - preserve `<model_switch>` across compaction by rebuilding it through
  canonical initial-context injection, instead of relying on
  strip/reattach hacks
  - centralize contextual user fragment detection in one shared definition
  table and reuse it for parsing/compaction logic
  - keep `AGENTS.md` in its natural serialized format:
    - `# AGENTS.md instructions for {dirname}`
    - `<INSTRUCTIONS>...</INSTRUCTIONS>`
  - simplify related tests/helpers and accept the expected snapshot/layout
  updates from bundled multi-part messages
  
  ## Why
  The goal is to converge toward a simpler, more intentional prompt shape
  where contextual updates are consistently represented as one developer
  envelope plus one contextual user envelope, while keeping parsing and
  compaction behavior aligned with that representation.
  
  ## Notable details
  - the temporary `SettingsUpdateEnvelope` wrapper was removed; these
  paths now return `Vec<ResponseItem>` directly
  - local/remote compaction no longer rely on model-switch strip/restore
  helpers
  - contextual user detection is now driven by shared fragment definitions
  instead of ad hoc matcher assembly
  - AGENTS/user instructions are still the same logical context; only the
  synthetic `<user_instructions>` wrapper was replaced by the natural
  AGENTS text format
  
  ## Testing
  - `just fmt`
  - `cargo test -p codex-app-server
  codex_message_processor::tests::extract_conversation_summary_prefers_plain_user_messages
  -- --exact`
  - `cargo test -p codex-core
  compact::tests::collect_user_messages_filters_session_prefix_entries

  --exact`
  - `cargo test -p core_test_support

  --exact`
  
  ## Notes
  - I also ran several targeted `compact`, `compact_remote`,
  `prompt_caching`, `model_visible_layout`, and `event_mapping` tests
  while iterating on prompt-shape changes.
  - I have not claimed a clean full-workspace `cargo test` from this
  environment because local sandbox/resource conditions have previously
  produced unrelated failures in large workspace runs.

• Enforce user input length cap (#12823)

  Currently there is no bound on the length of a user message submitted in
  the TUI or through the app server interface. That means users can paste
  many megabytes of text, which can lead to bad performance, hangs, and
  crashes. In extreme cases, it can lead to a [kernel
  panic](https://github.com/openai/codex/issues/12323).
  
  This PR limits the length of a user input to 2**20 (about 1M)
  characters. This value was chosen because it fills the entire context
  window on the latest models, so accepting longer inputs wouldn't make
  sense anyway.
  
  Summary
  - add a shared `MAX_USER_INPUT_TEXT_CHARS` constant in codex-protocol
  and surface it in TUI and app server code
  - block oversized submissions in the TUI submit flow and emit error
  history cells when validation fails
  - reject heavy app-server requests with JSON-RPC `-32602` and structured
  `input_too_large` data, plus document the behavior
  
  Testing
  - ran the IDE extension with this change and verified that when I
  attempt to paste a user message that's several MB long, it correctly
  reports an error instead of crashing or making my computer hot.

• feat: include available decisions in command approval requests (#12758)

  Command-approval clients currently infer which choices to show from
  side-channel fields like `networkApprovalContext`,
  `proposedExecpolicyAmendment`, and `additionalPermissions`. That makes
  the request shape harder to evolve, and it forces each client to
  replicate the server's heuristics instead of receiving the exact
  decision list for the prompt.
  
  This PR introduces a mapping between `CommandExecutionApprovalDecision`
  and `codex_protocol::protocol::ReviewDecision`:
  
  ```rust
  impl From<CoreReviewDecision> for CommandExecutionApprovalDecision {
      fn from(value: CoreReviewDecision) -> Self {
          match value {
              CoreReviewDecision::Approved => Self::Accept,
              CoreReviewDecision::ApprovedExecpolicyAmendment {
                  proposed_execpolicy_amendment,
              } => Self::AcceptWithExecpolicyAmendment {
                  execpolicy_amendment: proposed_execpolicy_amendment.into(),
              },
              CoreReviewDecision::ApprovedForSession => Self::AcceptForSession,
              CoreReviewDecision::NetworkPolicyAmendment {
                  network_policy_amendment,
              } => Self::ApplyNetworkPolicyAmendment {
                  network_policy_amendment: network_policy_amendment.into(),
              },
              CoreReviewDecision::Abort => Self::Cancel,
              CoreReviewDecision::Denied => Self::Decline,
          }
      }
  }
  ```
  
  And updates `CommandExecutionRequestApprovalParams` to have a new field:
  
  ```rust
  available_decisions: Option<Vec<CommandExecutionApprovalDecision>>
  ```
  
  when, if specified, should make it easier for clients to display an
  appropriate list of options in the UI.
  
  This makes it possible for `CoreShellActionProvider::prompt()` in
  `unix_escalation.rs` to specify the `Vec<ReviewDecision>` directly,
  adding support for `ApprovedForSession` when approving a skill script,
  which was previously missing in the TUI.
  
  Note this results in a significant change to `exec_options()` in
  `approval_overlay.rs`, as the displayed options are now derived from
  `available_decisions: &[ReviewDecision]`.
  
  ## What Changed
  
  - Add `available_decisions` to
  [`ExecApprovalRequestEvent`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/protocol/src/approvals.rs#L111-L175),
  including helpers to derive the legacy default choices when older
  senders omit the field.
  - Map `codex_protocol::protocol::ReviewDecision` to app-server
  `CommandExecutionApprovalDecision` and expose the ordered list as
  experimental `availableDecisions` in
  [`CommandExecutionRequestApprovalParams`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/app-server-protocol/src/protocol/v2.rs#L3798-L3807).
  - Thread optional `available_decisions` through the core approval path
  so Unix shell escalation can explicitly request `ApprovedForSession` for
  session-scoped approvals instead of relying on client heuristics.
  [`unix_escalation.rs`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/core/src/tools/runtimes/shell/unix_escalation.rs#L194-L214)
  - Update the TUI approval overlay to build its buttons from the ordered
  decision list, while preserving the legacy fallback when
  `available_decisions` is missing.
  - Update the app-server README, test client output, and generated schema
  artifacts to document and surface the new field.
  
  ## Testing
  
  - Add `approval_overlay.rs` coverage for explicit decision lists,
  including the generic `ApprovedForSession` path and network approval
  options.
  - Update `chatwidget/tests.rs` and app-server protocol tests to populate
  the new optional field and keep older event shapes working.
  
  ## Developers Docs
  
  - If we document `item/commandExecution/requestApproval` on
  [developers.openai.com/codex](https://developers.openai.com/codex), add
  experimental `availableDecisions` as the preferred source of approval
  choices and note that older servers may omit it.

• feat(app-server): thread/unsubscribe API (#10954)

  Adds a new v2 app-server API for a client to be able to unsubscribe to a
  thread:
  - New RPC method: `thread/unsubscribe`
  - New server notification: `thread/closed`
  
  Today clients can start/resume/archive threads, but there wasn’t a way
  to explicitly unload a live thread from memory without archiving it.
  With `thread/unsubscribe`, a client can indicate it is no longer
  actively working with a live Thread. If this is the only client
  subscribed to that given thread, the thread will be automatically closed
  by app-server, at which point the server will send `thread/closed` and
  `thread/status/changed` with `status: notLoaded` notifications.
  
  This gives clients a way to prevent long-running app-server processes
  from accumulating too many thread (and related) objects in memory.
  
  Closed threads will also be removed from `thread/loaded/list`.

• feat(app-server): add ThreadItem::DynamicToolCall (#12732)

  Previously, clients would call `thread/start` with dynamic_tools set,
  and when a model invokes a dynamic tool, it would just make the
  server->client `item/tool/call` request and wait for the client's
  response to complete the tool call. This works, but it doesn't have an
  `item/started` or `item/completed` event.
  
  Now we are doing this:
  - [new] emit `item/started` with `DynamicToolCall` populated with the
  call arguments
  - send an `item/tool/call` server request
  - [new] once the client responds, emit `item/completed` with
  `DynamicToolCall` populated with the response.
  
  Also, with `persistExtendedHistory: true`, dynamic tool calls are now
  reconstructable in `thread/read` and `thread/resume` as
  `ThreadItem::DynamicToolCall`.

• feat(network-proxy): add embedded OTEL policy audit logging (#12046)

  **PR Summary**
  
  This PR adds embedded-only OTEL policy audit logging for
  `codex-network-proxy` and threads audit metadata from `codex-core` into
  managed proxy startup.
  
  ### What changed
  - Added structured audit event emission in `network_policy.rs` with
  target `codex_otel.network_proxy`.
  - Emitted:
  - `codex.network_proxy.domain_policy_decision` once per domain-policy
  evaluation.
    - `codex.network_proxy.block_decision` for non-domain denies.
  - Added required policy/network fields, RFC3339 UTC millisecond
  `event.timestamp`, and fallback defaults (`http.request.method="none"`,
  `client.address="unknown"`).
  - Added non-domain deny audit emission in HTTP/SOCKS handlers for
  mode-guard and proxy-state denies, including unix-socket deny paths.
  - Added `REASON_UNIX_SOCKET_UNSUPPORTED` and used it for unsupported
  unix-socket auditing.
  - Added `NetworkProxyAuditMetadata` to runtime/state, re-exported from
  `lib.rs` and `state.rs`.
  - Added `start_proxy_with_audit_metadata(...)` in core config, with
  `start_proxy()` delegating to default metadata.
  - Wired metadata construction in `codex.rs` from session/auth context,
  including originator sanitization for OTEL-safe tagging.
  - Updated `network-proxy/README.md` with embedded-mode audit schema and
  behavior notes.
  - Refactored HTTP block-audit emission to a small local helper to reduce
  duplication.
  - Preserved existing unix-socket proxy-disabled host/path behavior for
  responses and blocked history while using an audit-only endpoint
  override (`server.address="unix-socket"`, `server.port=0`).
  
  ### Explicit exclusions
  - No standalone proxy OTEL startup work.
  - No `main.rs` binary wiring.
  - No `standalone_otel.rs`.
  - No standalone docs/tests.
  
  ### Tests
  - Extended `network_policy.rs` tests for event mapping, metadata
  propagation, fallbacks, timestamp format, and target prefix.
  - Extended HTTP tests to assert unix-socket deny block audit events.
  - Extended SOCKS tests to cover deny emission from handler deny
  branches.
  - Added/updated core tests to verify audit metadata threading into
  managed proxy state.
  
  ### Validation run
  - `just fmt`
  - `cargo test -p codex-network-proxy` ✅
  - `cargo test -p codex-core` ran with one unrelated flaky timeout
  (`shell_snapshot::tests::snapshot_shell_does_not_inherit_stdin`), and
  the test passed when rerun directly ✅

• feat: add experimental additionalPermissions to v2 command execution approval requests (#12737)

  This adds additionalPermissions to the app-server v2

• feat: pass helper executable paths via Arg0DispatchPaths (#12719)

  ## Why
  
  `codex-rs/core/src/tools/runtimes/shell/unix_escalation.rs` previously
  located `codex-execve-wrapper` by scanning `PATH` and sibling
  directories. That lookup is brittle and can select the wrong binary when
  the runtime environment differs from startup assumptions.
  
  We already pass `codex-linux-sandbox` from `codex-arg0`;
  `codex-execve-wrapper` should use the same startup-driven path plumbing.
  
  ## What changed
  
  - Introduced `Arg0DispatchPaths` in `codex-arg0` to carry both helper
  executable paths:
    - `codex_linux_sandbox_exe`
    - `main_execve_wrapper_exe`
  - Updated `arg0_dispatch_or_else()` to pass `Arg0DispatchPaths` to
  top-level binaries and preserve helper paths created in
  `prepend_path_entry_for_codex_aliases()`.
  - Threaded `Arg0DispatchPaths` through entrypoints in `cli`, `exec`,
  `tui`, `app-server`, and `mcp-server`.
  - Added `main_execve_wrapper_exe` to core configuration plumbing
  (`Config`, `ConfigOverrides`, and `SessionServices`).
  - Updated zsh-fork shell escalation to consume the configured
  `main_execve_wrapper_exe` and removed path-sniffing fallback logic.
  - Updated app-server config reload paths so reloaded configs keep the
  same startup-provided helper executable paths.

  - add a websocket integration test that verifies Ctrl-C waits for an
  in-flight turn before exit
  
  ## Verification

• Ensure shell command skills trigger approval (#12697)

  Summary
  - detect skill-invoking shell commands based on the original command
  string, request approvals when needed, and cache positive decisions per
  session
  - keep implicit skill invocation emitted after approval and keep skill
  approval decline messaging centralized to the shell handler
  - expand and adjust skill approval tests to cover shell-based skill
  scripts while matching the new detection expectations
  
  Testing
  - Not run (not requested)

• feat: run zsh fork shell tool via shell-escalation (#12649)

  ## Why
  
  This PR switches the `shell_command` zsh-fork path over to
  `codex-shell-escalation` so the new shell tool can use the shared
  exec-wrapper/escalation protocol instead of the `zsh_exec_bridge`
  implementation that was introduced in
  https://github.com/openai/codex/pull/12052. `zsh_exec_bridge` relied on
  UNIX domain sockets, which is not as tamper-proof as the FD-based
  approach in `codex-shell-escalation`.
  
  ## What Changed
  
  - Added a Unix zsh-fork runtime adapter in `core`
  (`core/src/tools/runtimes/shell/unix_escalation.rs`) that:
  - runs zsh-fork commands through
  `codex_shell_escalation::run_escalate_server`
    - bridges exec-policy / approval decisions into `ShellActionProvider`
  - executes escalated commands via a `ShellCommandExecutor` that calls
  `process_exec_tool_call`
  - Updated `ShellRuntime` / `ShellCommandHandler` / tool spec wiring to
  select a `shell_command` backend (`classic` vs `zsh-fork`) while leaving
  the generic `shell` tool path unchanged.
  - Removed the `zsh_exec_bridge`-based session service and deleted
  `core/src/zsh_exec_bridge/mod.rs`.
  - Moved exec-wrapper entrypoint dispatch to `arg0` by handling the
  `codex-execve-wrapper` arg0 alias there, and removed the old
  `codex_core::maybe_run_zsh_exec_wrapper_mode()` hooks from `cli` and
  `app-server` mains.
  - Added the needed `codex-shell-escalation` dependencies for `core` and
  `arg0`.
  
  ## Tests
  
  - `cargo test -p codex-core
  shell_zsh_fork_prefers_shell_command_over_unified_exec`
  - `cargo test -p codex-app-server turn_start_shell_zsh_fork --
  --nocapture`
  - verifies zsh-fork command execution and approval flows through the new
  backend
  - includes subcommand approve/decline coverage using the shared zsh
  DotSlash fixture in `app-server/tests/suite/zsh`
  - To test manually, I added the following to `~/.codex/config.toml`:
  
  ```toml
  zsh_path = "/Users/mbolin/code/codex3/codex-rs/app-server/tests/suite/zsh"
  
  [features]
  shell_zsh_fork = true
  ```
  
  Then I ran `just c` to run the dev build of Codex with these changes and
  sent it the message:
  
  ```
  run `echo $0`
  ```
  
  And it replied with:
  
  ```
    echo $0 printed:
  
    /Users/mbolin/code/codex3/codex-rs/app-server/tests/suite/zsh
  
    In this tool context, $0 reflects the script path used to invoke the shell, not just zsh.
  ```
  
  so the tool appears to be wired up correctly.
  
  ## Notes
  
  - The zsh subcommand-decline integration test now uses `rm` under a
  `WorkspaceWrite` sandbox. The previous `/usr/bin/true` scenario is
  auto-allowed by the new `shell-escalation` policy path, which no longer
  produces subcommand approval prompts.

• test: vendor zsh fork via DotSlash and stabilize zsh-fork tests (#12518)

  ## Why
  
  The zsh integration tests were still brittle in two ways:
  
  - they relied on `CODEX_TEST_ZSH_PATH` / environment-specific setup, so
  they often did not exercise the patched zsh fork that `shell-tool-mcp`
  ships
  - once the tests consistently used the vendored zsh fork, they exposed
  real Linux-specific zsh-fork issues in CI
  
  In particular, the Linux failures were not just test noise:
  
  - the zsh-fork launch path was dropping `ExecRequest.arg0`, so Linux
  `codex-linux-sandbox` arg0 dispatch did not run and zsh wrapper-mode
  could receive malformed arguments
  - the
  `turn_start_shell_zsh_fork_subcommand_decline_marks_parent_declined_v2`
  test uses the zsh exec bridge (which talks to the parent over a Unix
  socket), but Linux restricted sandbox seccomp denies `connect(2)`,
  causing timeouts on `ubuntu-24.04` x86/arm
  
  This PR makes the zsh tests consistently run against the intended
  vendored zsh fork and fixes/hardens the zsh-fork path so the Linux CI
  signal is meaningful.
  
  ## What Changed
  
  - Added a single shared test-only DotSlash file for the patched zsh fork
  at `codex-rs/exec-server/tests/suite/zsh` (analogous to the existing
  `bash` test resource).
  - Updated both app-server and exec-server zsh tests to use that shared
  DotSlash zsh (no duplicate zsh DotSlash file, no `CODEX_TEST_ZSH_PATH`
  dependency).
  - Updated the app-server zsh-fork test helper to resolve the shared
  DotSlash zsh and avoid silently falling back to host zsh.
  - Kept the app-server zsh-fork tests configured via `config.toml`, using
  a test wrapper path where needed to force `zsh -df` (and rewrite `-lc`
  to `-c`) for the subcommand-decline test.
  - Hardened the app-server subcommand-decline zsh-fork test for CI
  variability:
    - tolerate an extra `/responses` POST with a no-op mock response
  - tolerate non-target approval ordering while remaining strict on the
  two `/usr/bin/true` approvals and decline behavior
  - use `DangerFullAccess` on Linux for this one test because it validates
  zsh approval flow, not Linux sandbox socket restrictions
  - Fixed zsh-fork process launching on Linux by preserving `req.arg0` in
  `ZshExecBridge::execute_shell_request(...)` so `codex-linux-sandbox`
  arg0 dispatch continues to work.
  - Moved `maybe_run_zsh_exec_wrapper_mode()` under
  `arg0_dispatch_or_else(...)` in `app-server` and `cli` so wrapper-mode
  handling coexists correctly with arg0-dispatched helper modes.
  - Consolidated duplicated `dotslash -- fetch` resolution logic into
  shared test support (`core/tests/common/lib.rs`).
  - Updated `codex-rs/exec-server/tests/suite/accept_elicitation.rs` to
  use DotSlash zsh and hardened the zsh elicitation test for Bazel/zsh
  differences by:
    - resolving an absolute `git` path
    - running `git init --quiet .`
  - asserting success / `.git` creation instead of relying on banner text
  
  ## Verification
  
  - `cargo test -p codex-app-server turn_start_zsh_fork -- --nocapture`
  - `cargo test -p codex-exec-server accept_elicitation -- --nocapture`
  - `bazel test //codex-rs/exec-server:exec-server-all-test
  --test_output=streamed --test_arg=--nocapture
  --test_arg=accept_elicitation_for_prompt_rule_with_zsh`
  - CI (`rust-ci`) on the final cleaned commit: `Tests — ubuntu-24.04 -

  aarch64-unknown-linux-gnu` passed in [run

• app-server: retain thread listener across disconnects (#12373)

  - keep the per-thread app-server listener alive when the last client
  unsubscribes or disconnects
  - preserve listener-side active turn history so running `thread/resume`

  - add `ThreadStateManager` regressions for disconnect/unsubscribe
  retention and explicit thread teardown cleanup
  
  Added unit tests, and I manually tested to confirm the fix

• chore: remove codex-core public protocol/shell re-exports (#12432)

  ## Why
  
  `codex-rs/core/src/lib.rs` re-exported a broad set of types and modules
  from `codex-protocol` and `codex-shell-command`. That made it easy for
  workspace crates to import those APIs through `codex-core`, which in
  turn hides dependency edges and makes it harder to reduce compile-time
  coupling over time.
  
  This change removes those public re-exports so call sites must import
  from the source crates directly. Even when a crate still depends on
  `codex-core` today, this makes dependency boundaries explicit and
  unblocks future work to drop `codex-core` dependencies where possible.
  
  ## What Changed
  
  - Removed public re-exports from `codex-rs/core/src/lib.rs` for:
  - `codex_protocol::protocol` and related protocol/model types (including
  `InitialHistory`)
    - `codex_protocol::config_types` (`protocol_config_types`)
  - `codex_shell_command::{bash, is_dangerous_command, is_safe_command,
  parse_command, powershell}`
  - Migrated workspace Rust call sites to import directly from:
    - `codex_protocol::protocol`
    - `codex_protocol::config_types`
    - `codex_protocol::models`
    - `codex_shell_command`
  - Added explicit `Cargo.toml` dependencies (`codex-protocol` /
  `codex-shell-command`) in crates that now import those crates directly.
  - Kept `codex-core` internal modules compiling by using `pub(crate)`
  aliases in `core/src/lib.rs` (internal-only, not part of the public
  API).
  - Updated the two utility crates that can already drop a `codex-core`
  dependency edge entirely:
    - `codex-utils-approval-presets`
    - `codex-utils-cli`
  
  ## Verification
  
  - `cargo test -p codex-utils-approval-presets`
  - `cargo test -p codex-utils-cli`
  - `cargo check --workspace --all-targets`
  - `just clippy`

• fix: address flakiness in thread_resume_rejoins_running_thread_even_with_override_mismatch (#12381)

  ## Why
  `thread/resume` responses for already-running threads can be reported as
  `Idle` even while a turn is still in progress. This is caused by a
  timing window where the runtime watch state has not yet observed the
  running-thread transition, so API clients can receive stale status
  information at resume time.
  
  Possibly related: https://github.com/openai/codex/pull/11786
  
  ## What
  - Add a shared status normalization helper, `resolve_thread_status`, in
  `codex-rs/app-server/src/thread_status.rs` that resolves
  `Idle`/`NotLoaded` to `Active { active_flags: [] }` when an in-progress
  turn is known.
  - Reuse this helper across thread response paths in
  `codex-rs/app-server/src/codex_message_processor.rs` (including
  `thread/start`, `thread/unarchive`, `thread/read`, `thread/resume`,
  `thread/fork`, and review/thread-started notification responses).
  - In `handle_pending_thread_resume_request`, use both the in-memory
  `active_turn_snapshot` and the resumed rollout turns to decide whether a
  turn is in progress before resolving thread status for the response.
  - Extend `thread_status` tests to validate the new status-resolution
  behavior directly.
  
  ## Verification
  - `cargo test -p codex-app-server
  suite::v2::thread_resume::thread_resume_rejoins_running_thread_even_with_override_mismatch`

• app-server: harden disconnect cleanup paths (#12218)

  Hardens codex-rs/app-server connection lifecycle and outbound routing
  for websocket clients. Fixes some FUD I was having
  
  - Added per-connection disconnect signaling (CancellationToken) for
  websocket transports.
  - Split websocket handling into independent inbound/outbound tasks
  coordinated by cancellation.
  - Changed outbound routing so websocket connections use non-blocking
  try_send; slow/full websocket writers are disconnected instead of
  stalling broadcast delivery.
  - Kept stdio behavior blocking-on-send (no forced disconnect) so local
  stdio clients are not dropped when queues are temporarily full.
  - Simplified outbound router flow by removing deferred
  pending_closed_connections handling.
  - Added guards to drop incoming response/notification/error messages
  from unknown connections.
  - Fixed listener teardown race in thread listener tasks using a
  listener_generation check so stale tasks do not clear newer listeners.
  
  Fixes
  https://linear.app/openai/issue/CODEX-4966/multiclient-handle-slow-notification-consumers
  
    ## Tests
  
    Added/updated transport tests covering:
  
    - broadcast does not block on a slow/full websocket connection
    - stdio connection waits instead of disconnecting on full queue
  
  I (maxj) have tested manually and will retest before landing

• fix(network-proxy): add unix socket allow-all and update seatbelt rules (#11368)

  ## Summary
  Adds support for a Unix socket escape hatch so we can bypass socket
  allowlisting when explicitly enabled.
  
  ## Description
  * added a new flag, `network.dangerously_allow_all_unix_sockets` as an
  explicit escape hatch
  * In codex-network-proxy, enabling that flag now allows any absolute
  Unix socket path from x-unix-socket instead of requiring each path to be
  explicitly allowlisted. Relative paths are still rejected.
  * updated the macOS seatbelt path in core so it enforces the same Unix
  socket behavior:
    * allowlisted sockets generate explicit network* subpath rules
    * allow-all generates a broad network* (subpath "/") rule

• Refactor network approvals to host/protocol/port scope (#12140)

  ## Summary
  Simplify network approvals by removing per-attempt proxy correlation and
  moving to session-level approval dedupe keyed by (host, protocol, port).
  Instead of encoding attempt IDs into proxy credentials/URLs, we now
  treat approvals as a destination policy decision.
  
  - Concurrent calls to the same destination share one approval prompt.
  - Different destinations (or same host on different ports) get separate
  prompts.
  - Allow once approves the current queued request group only.
  - Allow for session caches that (host, protocol, port) and auto-allows
  future matching requests.
  - Never policy continues to deny without prompting.
  
  Example:
  - 3 calls: 
    - a.com (line 443)
    - b.com (line 443)
    - a.com (line 443)
  => 2 prompts total (a, b), second a waits on the first decision.
  - a.com:80 is treated separately from a.com line 443
  
  ## Testing
  - `just fmt` (in `codex-rs`)
  - `cargo test -p codex-core tools::network_approval::tests`
  - `cargo test -p codex-core` (unit tests pass; existing
  integration-suite failures remain in this environment)

• Add configurable MCP OAuth callback URL for MCP login (#11382)

  ## Summary
  
  Implements a configurable MCP OAuth callback URL override for `codex mcp
  login` and app-server OAuth login flows, including support for non-local
  callback endpoints (for example, devbox ingress URLs).
  
  ## What changed
  
  - Added new config key: `mcp_oauth_callback_url` in
  `~/.codex/config.toml`.
  - OAuth authorization now uses `mcp_oauth_callback_url` as
  `redirect_uri` when set.
  - Callback handling validates the callback path against the configured
  redirect URI path.
  - Listener bind behavior is now host-aware:
  - local callback URL hosts (`localhost`, `127.0.0.1`, `::1`) bind to
  `127.0.0.1`
    - non-local callback URL hosts bind to `0.0.0.0`
  - `mcp_oauth_callback_port` remains supported and is used for the
  listener port.
  - Wired through:
    - CLI MCP login flow
    - App-server MCP OAuth login flow
    - Skill dependency OAuth login flow
  - Updated config schema and config tests.
  
  ## Why
  
  Some environments need OAuth callbacks to land on a specific reachable
  URL (for example ingress in remote devboxes), not loopback. This change
  allows that while preserving local defaults for existing users.
  
  ## Backward compatibility
  
  - No behavior change when `mcp_oauth_callback_url` is unset.
  - Existing `mcp_oauth_callback_port` behavior remains intact.
  - Local callback flows continue binding to loopback by default.
  
  ## Testing
  
  - `cargo test -p codex-rmcp-client callback -- --nocapture`
  - `cargo test -p codex-core --lib mcp_oauth_callback -- --nocapture`
  - `cargo check -p codex-cli -p codex-app-server -p codex-rmcp-client`
  
  ## Example config

  mcp_oauth_callback_port = 5555
  mcp_oauth_callback_url = "https://<devbox>-<namespace>.gateway.<cluster>.internal.api.openai.org/callback"

• client side modelinfo overrides (#12101)

  TL;DR
  Add top-level `model_catalog_json` config support so users can supply a
  local model catalog override from a JSON file path (including adding new
  models) without backend changes.
  
  ### Problem
  Codex previously had no clean client-side way to replace/overlay model
  catalog data for local testing of model metadata and new model entries.
  
  ### Fix
  - Add top-level `model_catalog_json` config field (JSON file path).
  - Apply catalog entries when resolving `ModelInfo`:
    1. Base resolved model metadata (remote/fallback)
    2. Catalog overlay from `model_catalog_json`
  3. Existing global top-level overrides (`model_context_window`,
  `model_supports_reasoning_summaries`, etc.)
  
  ### Note
  Will revisit per-field overrides in a follow-up
  
  ### Tests
  Added tests

• app-server: expose loaded thread status via read/list and notifications (#11786)

  Motivation
  - Today, a newly connected client has no direct way to determine the
  current runtime status of threads from read/list responses alone.
  - This forces clients to infer state from transient events, which can
  lead to stale or inconsistent UI when reconnecting or attaching late.
  
  Changes
  - Add `status` to `thread/read` responses.
  - Add `statuses` to `thread/list` responses.
  - Emit `thread/status/changed` notifications with `threadId` and the new
  status.
  - Track runtime status for all loaded threads and default unknown
  threads to `idle`.
  - Update protocol/docs/tests/schema fixtures for the revised API.
  
  Testing
  - Validated protocol API changes with automated protocol tests and
  regenerated schema/type fixtures.
  - Validated app-server behavior with unit and integration test suites,
  including status transitions and notifications.

• feat(core): zsh exec bridge (#12052)

  zsh fork PR stack:
  - https://github.com/openai/codex/pull/12051 
  - https://github.com/openai/codex/pull/12052 👈 
  
  ### Summary
  This PR introduces a feature-gated native shell runtime path that routes
  shell execution through a patched zsh exec bridge, removing MCP-specific
  behavior from the shell hot path while preserving existing
  CommandExecution lifecycle semantics.
  
  When shell_zsh_fork is enabled, shell commands run via patched zsh with
  per-`execve` interception through EXEC_WRAPPER. Core receives wrapper
  IPC requests over a Unix socket, applies existing approval policy, and
  returns allow/deny before the subcommand executes.
  
  ### What’s included
  **1) New zsh exec bridge runtime in core**
  - Wrapper-mode entrypoint (maybe_run_zsh_exec_wrapper_mode) for
  EXEC_WRAPPER invocations.
  - Per-execution Unix-socket IPC handling for wrapper requests/responses.
  - Approval callback integration using existing core approval
  orchestration.
  - Streaming stdout/stderr deltas to existing command output event
  pipeline.
  - Error handling for malformed IPC, denial/abort, and execution
  failures.
  
  **2) Session lifecycle integration**
  SessionServices now owns a `ZshExecBridge`.
  Session startup initializes bridge state; shutdown tears it down
  cleanly.
  
  **3) Shell runtime routing (feature-gated)**
  When `shell_zsh_fork` is enabled:
  - Build execution env/spec as usual.
  - Add wrapper socket env wiring.
  - Execute via `zsh_exec_bridge.execute_shell_request(...)` instead of
  the regular shell path.
  - Non-zsh-fork behavior remains unchanged.
  
  **4) Config + feature wiring**
  - Added `Feature::ShellZshFork` (under development).
  - Added config support for `zsh_path` (optional absolute path to patched
  zsh):
  - `Config`, `ConfigToml`, `ConfigProfile`, overrides, and schema.
  - Session startup validates that `zsh_path` exists/usable when zsh-fork
  is enabled.
  - Added startup test for missing `zsh_path` failure mode.
  
  **5) Seatbelt/sandbox updates for wrapper IPC**
  - Extended seatbelt policy generation to optionally allow outbound
  connection to explicitly permitted Unix sockets.
  - Wired sandboxing path to pass wrapper socket path through to seatbelt
  policy generation.
  - Added/updated seatbelt tests for explicit socket allow rule and
  argument emission.
  
  **6) Runtime entrypoint hooks**
  - This allows the same binary to act as the zsh wrapper subprocess when
  invoked via `EXEC_WRAPPER`.
  
  **7) Tool selection behavior**
  - ToolsConfig now prefers ShellCommand type when shell_zsh_fork is
  enabled.
  - Added test coverage for precedence with unified-exec enabled.

• feat(core): plumb distinct approval ids for command approvals (#12051)

  zsh fork PR stack:
  - https://github.com/openai/codex/pull/12051 👈 
  - https://github.com/openai/codex/pull/12052
  
  With upcoming support for a fork of zsh that allows us to intercept
  `execve` and run execpolicy checks for each subcommand as part of a
  `CommandExecution`, it will be possible for there to be multiple
  approval requests for a shell command like `/path/to/zsh -lc 'git status
  && rg \"TODO\" src && make test'`.
  
  To support that, this PR introduces a new `approval_id` field across
  core, protocol, and app-server so that we can associate approvals
  properly for subcommands.

• app-server: Emit thread archive/unarchive notifications (#12030)

  * Add v2 server notifications `thread/archived` and `thread/unarchived`
  with a `threadId` payload.
  * Wire new events into `thread/archive` and `thread/unarchive` success
  paths.
  * Update app-server protocol/schema/docs accordingly.
  
  Testing:
  - Updated archive/unarchive end-to-end tests to verify both
  notifications are emitted with the expected thread id payload.

• chore: rm remote models fflag (#11699)

  rm `remote_models` feature flag.
  
  We see issues like #11527 when a user has `remote_models` disabled, as
  we always use the default fallback `ModelInfo`. This causes issues with
  model performance.
  
  Builds on #11690, which helps by warning the user when they are using
  the default fallback. This PR will make that happen much less frequently
  as an accidental consequence of disabling `remote_models`.

• Feat: add model reroute notification (#12001)

  ### Summary
  Builiding off
  https://github.com/openai/codex/pull/11964/files/5c75aa7b89a70bc2cc410a6fd238749306ec4c5e#diff-058ae8f109a8b84b4b79bbfa45f522c2233b9d9e139696044ae374d50b6196e0,
  we have created a `model/rerouted` notification that captures the event
  so that consumers can render as expected. Keep the `EventMsg::Warning`
  path in core so that this does not affect TUI rendering.
  
  `model/rerouted` is meant to be generic to account for future usage
  including capacity planning etc.
