• core: derive built-in permission profiles from raw policies (#25739)

  ## Why
  
  Permission profiles that extend a built-in profile should behave like
  other TOML inheritance: parent entries provide defaults, and child keys
  override matching fields before the profile is compiled.
  
  That was not true for `:workspace`. Previously, a profile with `extends
  = ":workspace"` seeded the compiled runtime
  `PermissionProfile::workspace_write()` policy and then appended child
  filesystem entries. A child override such as `":tmpdir" = "read"`
  therefore left the inherited `":tmpdir" = "write"` entry in the final
  policy. Since same-target `write` wins over `read` during runtime
  resolution, the child override was ineffective.
  
  This also needs a clear source of truth for the built-in profiles. The
  protocol-level sandbox policy constructors now define the raw built-in
  filesystem entries, and both `PermissionProfile` presets and
  config-profile inheritance derive from those same values.
  
  ## What Changed
  
  - Add a canonical `FileSystemSandboxPolicy::read_only()` constructor
  while keeping the read-only and workspace-write raw filesystem entries
  explicit and independent.
  - Derive `PermissionProfile::read_only()` from
  `FileSystemSandboxPolicy::read_only()`;
  `PermissionProfile::workspace_write()` continues to derive from
  `FileSystemSandboxPolicy::workspace_write()`.
  - Build extensible `:read-only` and `:workspace` parent profiles by
  projecting those canonical sandbox policies into
  `PermissionProfileToml`, then merge user overrides at the TOML layer
  before compilation.
  - Add config parsing support for `:slash_tmp` so the built-in
  `:workspace` parent can be expressed in the same TOML-shaped filesystem
  table as user profiles.
  - Document that `PermissionsToml::resolve_profile()` returns an
  already-merged `PermissionProfileToml`, and return that profile directly
  after removing the resolved-profile wrapper.
  - Extend the config test for `extends = ":workspace"` to assert that
  inherited `":slash_tmp" = "write"` is preserved and that a child
  `":tmpdir" = "read"` entry replaces the inherited `write` entry.
  
  ## Verification
  
  - `just test -p codex-config`
  - `just test -p codex-protocol`
  - `just test -p codex-core

  - `just test -p codex-core`
    - Result: 2596 passed, 4 failed, 1 timed out.
  - The failures were existing sandbox/environment-sensitive tests
  unrelated to this permissions change:

• Skip startup prewarm when websockets are disabled (#25868)

  ## Summary
  - skip startup websocket prewarm setup when the model client has
  Responses-over-WebSocket disabled
  - avoid making HTTP-only sessions build prewarm prompt/tool state that
  cannot produce a reusable websocket session
  
  ## Why
  Recent macOS timing flakes were timing out while waiting for first-turn
  events in HTTP-only core tests. Startup prewarm is only useful for
  websocket-capable providers, but it was scheduled for every session. For
  HTTP-only test providers this added unnecessary async startup work
  before the regular turn could reach the mocked response flow.
  
  ## Testing
  - bazel test //codex-rs/core:core-all-test
  --test_filter=suite::auto_review::remote_model_override_uses_catalog_model_for_strict_auto_review

• flake: Keep plugin test homes alive (#25857)

  ## Summary
  
  Keep the full `TestCodex` harness alive in plugin integration tests
  instead of returning only the `CodexThread`.
  
  ## Why
  
  The helper was moving a temporary `codex_home` into `TestCodex`, then
  immediately dropping the harness and returning only the thread. For
  plugin MCP tests, the MCP server cwd is inside that temporary home. If
  the temp directory is removed while MCP startup is still racing, the
  server launch can fail with `No such file or directory`.
  
  Keeping the harness in scope keeps the temp home alive for the test
  duration and removes the lifetime race behind the recent
  `explicit_plugin_mentions_inject_plugin_guidance` flake.
  
  ## Validation
  
  - `just fmt`
  - `just test -p codex-core

• Reduce stack pressure in session startup and config rebuilds (#25844)

  ## Why
  
  `/clear` starts a fresh thread with `InitialHistory::Cleared`, which
  re-enters the thread/session startup path. That path now builds large
  async futures through `ThreadManagerState::spawn_thread_with_source`,
  `Codex::spawn`, and `Session::new`. Separately, TUI config rebuilds for
  cwd and permission-profile changes build a similarly heavy
  `ConfigBuilder::build()` future inside the app task. In debug and Bazel
  runs, those call chains can put enough state on the caller stack to
  abort before startup or config refresh completes.
  
  This change keeps the behavior the same while moving the heaviest future
  frames off the caller stack.
  
  ## What changed
  
  - Box `Codex::spawn(...)` in `codex-rs/core/src/thread_manager.rs`
  before awaiting it from `spawn_thread_with_source`.
  - Box `Session::new(...)` in `codex-rs/core/src/session/mod.rs` before
  awaiting it from `Codex::spawn_internal`.
  - Route `ConfigBuilder::build()` through a small `tokio::spawn` helper
  in `codex-rs/tui/src/app/config_persistence.rs` so cwd and
  permission-profile config rebuilds run on a runtime worker stack while
  preserving error context.
  
  ## Verification
  
  CI is running on the PR.
  
  No new targeted tests were added. This is a mechanical stack-pressure
  reduction that keeps the existing behavior and error propagation intact.

• session: keep startup prewarm aligned with resolved multi-agent runtime (#25841)

  ## Why
  
  Follow-up to #25722. Startup prewarm builds a preview `TurnContext`
  before the first real turn so it can precompute the initial prompt and
  tool surface. After the per-thread runtime work landed, that preview
  path still recomputed multi-agent mode from `model_info` and feature
  defaults instead of reusing the runtime the session had already resolved
  from persisted metadata or inheritance.
  
  That could leave the prewarmed session primed for a different
  multi-agent mode than the first real turn, which is especially risky
  because collaboration tool exposure depends on
  `turn_context.multi_agent_version`.
  
  ## What changed
  
  - In the `TurnMultiAgentRuntime::Preview` path, prefer
  `Session::multi_agent_version()` when it is already known.
  - Only fall back to `model_info.multi_agent_version` and feature
  defaults when the session has not resolved a runtime yet.
  - Keep preview mode read-only: this still avoids storing a runtime
  during startup prewarm.
  
  ## Testing
  
  - Not run (small runtime-selection follow-up)

• feat: show enterprise monthly credit limits in status (#24812)

  ## Summary
  
  Enterprise users can have an effective monthly credit limit, but Codex
  `/status` currently drops that metadata from the account-usage response.
  
  This change adds the optional `spend_control.individual_limit`
  projection to the existing rate-limit snapshot flow. The backend client
  reads the monthly limit, app-server exposes it as `individualLimit`, and
  the TUI renders a `Monthly credit limit` row through the existing
  progress-bar renderer.
  
  When the backend does not return an effective monthly limit, existing
  rate-limit behavior is unchanged.
  
  ## Existing backend state
  
  The account-usage backend already returns the effective monthly limit
  and current usage together:
  
  ```json
  {
    "spend_control": {
      "reached": false,
      "individual_limit": {
        "limit": "25000",
        "used": "8000",
        "remaining": "17000",
        "used_percent": 32,
        "remaining_percent": 68,
        "reset_after_seconds": 86400,
        "reset_at": 1778137680
      }
    }
  }
  ```
  
  Before this change, Codex projected rolling `primary` and `secondary`
  windows plus `credits`. It ignored `spend_control.individual_limit`, so
  app-server clients and `/status` could not render the monthly cap.
  
  The updated flow is:
  
  ```text
  account usage backend
    -> backend-client reads spend_control.individual_limit
    -> existing rate-limit snapshot carries optional individual_limit
    -> app-server exposes optional individualLimit
    -> TUI renders Monthly credit limit
  ```
  
  ## App-server contract
  
  `account/rateLimits/read` and sparse `account/rateLimits/updated`
  notifications now include an additive nullable
  `rateLimits.individualLimit` field:
  
  ```json
  {
    "individualLimit": {
      "limit": "25000",
      "used": "8000",
      "remainingPercent": 68,
      "resetsAt": 1778137680
    }
  }
  ```
  
  In an `account/rateLimits/read` response, `null` means no monthly limit
  is available. `account/rateLimits/updated` remains a sparse rolling
  notification: clients merge available values into their most recent
  `account/rateLimits/read` snapshot or refetch. Nullable account metadata
  in a rolling notification does not clear a previously observed value.
  
  ## Design decisions
  
  - Extend the existing rate-limit snapshot instead of introducing a
  separate request or wire-level update protocol.
  - Keep the Codex projection narrow: `/status` needs the effective limit,
  current usage, remaining percentage, and reset timestamp.
  - Render the monthly row through the existing progress-bar renderer,
  with one optional detail line for `8,000 of 25,000 credits used`.
  - Keep the backend response optional so existing accounts and older
  usage states preserve their current behavior.
  - Preserve cached monthly metadata when sparse rolling notifications
  omit it. Live account-usage reads remain authoritative and can clear a
  removed limit.
  
  ## Visual evidence
  
  ```text
   Monthly credit limit:   [██████████████░░░░░░] 68% left (resets 07:08 on 7 May)
                           8,000 of 25,000 credits used
  ```
  
  Snapshot:
  `codex-rs/tui/src/status/snapshots/codex_tui__status__tests__status_snapshot_includes_enterprise_monthly_credit_limit.snap`
  
  ## Testing
  
  Tests: generated app-server schema verification, protocol tests,
  backend-client tests, app-server integration coverage, TUI snapshot
  coverage, formatting, and workspace lint cleanup.

• Wire managed MITM CA trust into child env (#22668)

  ## Stack
  1. Parent PR: #18240 uses named MITM permissions config.
  2. This PR wires managed MITM CA trust into spawned child processes.
  
  ## Why
  When Codex terminates HTTPS for limited mode or MITM hooks, child HTTPS
  clients need to trust Codex's managed MITM CA. Exporting proxy URLs
  alone is not enough, but blindly replacing user CA settings would be
  wrong: it can break custom enterprise/test roots, leak unreadable CA
  files into generated bundles, or make the child env disagree with its
  sandbox policy.
  
  ## Summary
  1. Build immutable managed CA bundles under `$CODEX_HOME/proxy` that
  include native roots, the managed MITM CA, and only inherited or
  command-scoped CA bundles the child is allowed to read.
  2. Export curated CA env vars alongside managed proxy env vars while
  preserving user CA override semantics, including nested Codex
  `SSL_CERT_FILE` precedence.
  3. Thread generated CA bundle paths into child sandbox readable roots,
  including debug sandbox execution, so the exported env vars work inside
  sandboxed commands.
  4. Remove only Codex-generated MITM CA bundle env when a child
  intentionally drops managed proxying for escalation or no-proxy retry.
  5. Document the managed CA bundle behavior and cover env injection,
  per-child bundle generation, sandbox readable roots, and no-proxy
  cleanup in tests.
  
  ## Validation
  1. Ran `just test -p codex-network-proxy`.
  2. Ran `just test -p codex-protocol`.
  3. Ran `just fix -p codex-network-proxy -p codex-protocol`.
  4. Tried focused `codex-core` validation, but the crate currently fails
  to compile in `core/tests/suite/guardian_review.rs` because an existing
  `Op::UserInput` initializer is missing `additional_context`.

• Move tool search metadata onto ToolExecutor (#25684)

  Deferred tools need to be searchable even when they are not implemented
  inside `codex-core`. Extension-provided tools can be registered for
  later discovery, but the search metadata path was still owned by
  core-specific runtime hooks, which meant the shared `ToolExecutor`
  abstraction could not describe how a deferred extension tool should
  appear in `tool_search`.
  
  ## Changes
  
  - Move `ToolSearchEntry` and `ToolSearchInfo` into `codex-tools` and
  re-export them from the shared tools crate.
  - Add a default `ToolExecutor::search_info` implementation that derives
  loadable tool-search metadata from function and namespace specs.
  - Forward search metadata through extension adapters and exposure
  overrides while keeping custom search text/source metadata for dynamic,
  MCP, and multi-agent tools.
  - Remove the old core-local `tool_search_entry` module now that search
  metadata lives with the shared executor APIs.
  
  ## Testing
  
  - Added `deferred_extension_tools_are_discoverable_with_tool_search`
  coverage in `core/src/tools/spec_plan_tests.rs`.

• refactor: hide shell override for zsh fork unified exec (#24980)

  ## Why
  
  When unified exec is configured to launch through the zsh fork, local
  commands should not let the model override the shell binary with the
  `shell` parameter. The configured zsh fork is the mechanism that makes
  `execv(2)` interception reliable, so exposing `shell` for local zsh-fork
  execution would create a confusing API surface and undermine the
  composition.
  
  Remote environments are different: zsh-fork interception is local-only,
  so remote unified-exec calls must keep direct unified-exec behavior and
  still expose `shell` when a remote environment can be selected.
  
  ## What Changed
  
  - Taught the `exec_command` schema builder to omit the `shell` parameter
  when requested.
  - Hid `shell` from the unified-exec tool schema only when zsh-fork
  unified exec applies to all selectable environments.
  - Kept `shell` visible when any remote environment can be targeted,
  because those calls run through direct unified exec.
  - Made unified exec choose the effective shell mode per selected
  environment: local environments keep zsh-fork mode, remote environments
  use direct mode.
  - Left direct unified-exec behavior unchanged, including support for
  model-specified shells there.
  
  ## Verification
  
  - Added schema coverage showing `exec_command` can hide `shell`.
  - Added planner coverage showing zsh-fork unified exec hides `shell` for
  local-only execution while direct unified exec still exposes it.
  - Added planner coverage showing `shell` remains visible when a remote
  environment is available.
  - Added handler coverage showing remote environments use direct
  unified-exec shell mode instead of zsh-fork mode.
  - Ran the focused `codex-core` shell-parameter and zsh-fork tests.

• feat: gate unified exec zsh fork composition (#24979)

  ## Why
  
  `shell_zsh_fork` and unified exec need to remain independently
  controllable for enterprise rollouts, but we also need a third mode that
  composes them. That composed mode is intended to preserve unified exec
  command lifecycle support while letting the zsh fork provide more
  accurate `execv(2)` interception.
  
  Enabling `unified_exec_zsh_fork` by itself is intentionally not
  sufficient. It is a composition gate, not a dependency-enabling
  shortcut:
  
  - `unified_exec` selects the PTY-backed unified exec tool.
  - `shell_zsh_fork` opts into the zsh fork backend.
  - `unified_exec_zsh_fork` only allows those two already-enabled modes to
  be composed so local zsh unified exec commands can launch through the
  zsh fork.
  
  This separation is deliberate. Enterprises and staged rollouts must be
  able to enable or disable unified exec and zsh-fork independently. If
  `unified_exec_zsh_fork` implied either dependency, then enabling one
  under-development composition flag would silently activate a shell
  backend that the configured feature set left disabled.
  
  This PR introduces only the configuration and planning gate for that
  composition. Existing `shell_zsh_fork` behavior continues to use the
  standalone shell tool unless the new composition feature is explicitly
  enabled alongside both dependencies.
  
  ## What Changed
  
  - Added the under-development feature flag `unified_exec_zsh_fork`.
  - Added `UnifiedExecFeatureMode` so the three input feature flags
  collapse into `Disabled`, `Direct`, or `ZshFork` mode before tool
  planning.
  - Updated tool selection so zsh-fork composition requires
  `unified_exec`, `shell_zsh_fork`, and `unified_exec_zsh_fork`.
  - Kept the existing standalone zsh-fork shell tool behavior when only
  `shell_zsh_fork` is enabled.
  - Updated config schema output for the new feature flag.
  
  ## Verification
  
  - Added feature and tool-config coverage for the new gate.
  - Added planner coverage proving `shell_zsh_fork` remains standalone
  until composition is explicitly enabled.
  - Ran focused tests for `codex-features`, `codex-tools`, and the
  affected `codex-core` planner case.

• [codex-rs] auto-review model override (#23767)

  ## Why
  
  Guardian auto-review normally uses the provider-preferred review model
  when one is available. Some parent models need model-catalog metadata to
  select a different review model while keeping older `/models` payloads
  compatible when that metadata is absent.
  
  ## What changed
  
  - Added optional `ModelInfo::auto_review_model_override` metadata to the
  public model payload as a review-model slug.
  - Updated Guardian review model selection to prefer the catalog override
  when present, while preserving the existing provider preferred-model
  path and parent-model fallback when it is omitted.
  - Added focused Guardian coverage for override and no-override model
  selection.
  - Added an `auto_review` core integration suite test that loads override
  metadata from a remote model catalog path and asserts the strict
  auto-review `/responses` request uses the catalog-selected review model.
  - Updated existing `ModelInfo` fixtures and local catalog constructors
  for the new optional field.
  
  ## Validation
  
  - `cargo test -p codex-protocol
  model_info_defaults_availability_nux_to_none_when_omitted`
  - `cargo test -p codex-core guardian_review_uses_`
  - `cargo test -p codex-core

• [codex] Consolidate shared prompts in codex-prompts (#25151)

  ## Why
  
  `codex_core` is consistently a bottleneck for incremental builds during
  iteration. The simplest fix is to make the crate smaller.
  
  ## Summary
  
  `codex-core` owns several reusable prompt renderers and static prompt
  assets, which makes the crate harder to split apart.
  
  Rename `codex-review-prompts` to `codex-prompts` and move shared review,
  goal, permissions, compaction, realtime, hierarchical AGENTS.md, and
  `apply_patch` prompts into it. Move prompt-only tests and update
  consumers and `CODEOWNERS`.
  
  ## Validation
  
  - `just test -p codex-prompts -p codex-apply-patch`
  - `just test -p codex-core prompt_caching`
  - Bazel builds for the affected crates

• [codex] Rename multi-agent v2 assign_task to followup_task (#25636)

  ## Summary
  
  Renames the MultiAgentV2 turn-triggering tool from `assign_task` to
  `followup_task` so the exposed tool name better describes sending an
  additional task to an existing agent.
  
  This updates the tool spec, handler/module names, registry wiring,
  default multi-agent v2 usage hints, and tests. Rollout trace
  classification keeps accepting legacy `assign_task` events so older
  traces still reduce correctly, while docs show the new tool name.
  
  ## Test plan
  
  - `just test -p codex-core followup_task`
  - `just test -p codex-core -E
  'test(multi_agent_feature_selects_one_agent_tool_family) |
  test(multi_agent_v2_can_use_configured_tool_namespace) |
  test(code_mode_only_can_expose_namespaced_multi_agent_v2_as_normal_tools)'`
  - `just test -p codex-rollout-trace`
  - `just fix -p codex-core`
  - `just fix -p codex-rollout-trace`
  
  Notes: `just fmt` ran `cargo fmt` but failed in the Python ruff phase
  because the local environment could not resolve `hatchling>=1.27.0` from
  the configured internal registry. A full `just test -p codex-core` also
  hit unrelated environment-sensitive integration failures involving
  missing spawned test binaries/sandbox behavior; the changed multi-agent
  spec/handler tests passed in the filtered runs above.

• Compress cold local rollouts (#25089)

  ## Rollout compression stack
  
  This stack splits #24941 into reviewable steps for local rollout
  compression. The design is intentionally staged:
  
  1. Teach readers, listing, search, and lookup to understand compressed
  rollouts.
  2. Make append and resume paths materialize compressed rollouts back to
  plain JSONL before writing.
  3. Add a disabled-by-default worker that can compress cold archived
  rollouts behind `local_thread_store_compression`.
  
  The key invariant is that writers append to plain `.jsonl`. A
  `.jsonl.zst` file is a cold/read representation; if a write is needed,
  the compressed file is materialized back to plain JSONL first. Readers
  prefer plain `.jsonl` when both forms exist and can fall back to the
  compressed sibling during transitions.
  
  The worker is deliberately the last PR and remains behind an
  under-development feature flag. It currently scans only
  `archived_sessions`, not active `sessions`, because active sessions have
  the highest resume/append race risk. That means this stack does not yet
  compress most unarchived local history.
  
  ## Known race / follow-up
  
  The remaining unresolved design question is writer/compressor
  coordination. Even for archived rollouts, a resume or metadata update
  can append while the worker is replacing the plain file with
  `.jsonl.zst`; the current double-stat checks narrow but do not fully
  eliminate the window where a writer has opened the plain file before
  unlink. Do not treat the worker PR as production-ready until we either:
  
  - prevent append/resume paths from racing archived compression, or
  - introduce a shared representation/append lock or equivalent
  coordination.
  
  The first two PRs are useful independently: they make compressed
  rollouts readable and make append paths safely recover back to plain
  JSONL. The third PR isolates the worker behavior so that coordination
  issue is reviewable separately.
  
  ## Validation
  
  Focused local validation for the stack includes:
  
  - `just test -p codex-rollout`
  - `just test -p codex-thread-store` where thread-store paths were
  touched
  - `just test -p codex-features` for the feature flag slice
  - `just bazel-lock-check` after dependency graph changes
  - scoped `just fix -p ...` passes for changed crates
  
  CI is still the source of truth for the full platform matrix.
  
  ## This PR in the stack
  
  This is PR 3/3, based on #25088. It adds the under-development feature
  flag and starts the best-effort background worker when enabled. The
  worker currently compresses only cold archived rollouts, skips active
  sessions, verifies compressed output, preserves mtime and permissions,
  keeps a store-level lock heartbeat, and cleans stale temp files.
  
  Stack order:
  
  1. #25087: read compressed local rollouts.
  2. #25088: materialize compressed rollouts before append.
  3. This PR: add the disabled local compression worker.

• Remove Plan-mode gate from idle turn injection (#25577)

  ## Why
  
  `try_start_turn_if_idle` is the core helper for starting injected input
  only when the session is actually idle. It should stay focused on
  generic turn-lifecycle safety. The previous `ModeKind::Plan` guard mixed
  caller policy into that helper: Plan mode may choose not to auto-start
  some extension work, but that decision belongs at the extension or
  caller boundary rather than in the session injection primitive.
  
  ## What changed
  
  - Removed the `ModeKind::Plan` early return from
  `Session::try_start_turn_if_idle`.
  - Removed the now-unused `ModeKind` import from
  `core/src/session/inject.rs`.
  
  ## Testing
  
  Not run locally.

• Add goal extension idle continuation (#25060)

  ## Why
  
  The goal extension needs a way to resume an active goal after the thread
  becomes idle, but the old core goal runtime should not be refactored as
  part of this step. The missing piece is a small core-owned turn-start
  primitive: let an extension ask for a normal model turn only when the
  thread is idle, and otherwise fail without injecting into whatever is
  currently active.
  
  ## What Changed
  
  - Adds `CodexThread::try_start_turn_if_idle(...)` as the narrow
  extension-facing primitive for synthetic idle work.
  - Implements the session side so it refuses to start when:
    - the provided input is empty,
    - the session is in plan mode,
    - a turn is already active, or
    - trigger-turn mailbox work is pending.
  - Gives trigger-turn mailbox work priority if it appears while the idle
  turn is being prepared.
  - Wires `GoalExtension::on_thread_idle` to read the active persisted
  goal and submit the continuation prompt through this idle-only
  primitive.
  - Keeps the legacy core goal continuation implementation in place
  instead of folding it into this PR.
  
  ## Behavior
  
  This is intentionally best-effort. If `try_start_turn_if_idle` observes
  that the thread is not idle, or that higher-priority mailbox work should
  run first, it returns the input to the caller. The goal extension drops
  that continuation prompt and waits for a future idle opportunity instead
  of injecting stale synthetic goal text into an active turn.
  
  ## Validation
  
  - `just test -p codex-core
  try_start_turn_if_idle_rejects_active_turn_without_injecting`
  - `just test -p codex-goal-extension`

• Set multi-agent v2 dogfood defaults (#25266)

  ## Summary
  - default multi-agent v2 to direct-model-only tools so code mode does

  - add default root/subagent team prompts aligned with dogfood training
  assumptions
  - tighten spawn-agent model override wording to prefer the inherited
  model by default
  
  ## Tests

  - just fix -p codex-core
  - just fix -p codex-rollout-trace
  
  Note: a broad just test -p codex-core run was attempted locally, but

• store and expose parent_thread_id on Threads (#25113)

  ## Why
  
  This PR
  https://github.com/openai/codex/pull/24161#discussion_r3325692763
  revealed a subagent data modeling issue, where we overloaded
  `forked_from_id` to also mean `parent_thread_id`. That's incorrect since
  guardian and review subagents can be a subagent and NOT fork the main
  thread's history.
  
  The solution here is to explicitly store a new `parent_thread_id` on
  `SessionMeta`, alongside `forked_from_id` which already exists. While
  we're at it, also expose it in the app-server protocol on the `Thread`
  object.
  
  A thread->subagent relationship and a fork of thread history are
  orthogonal concepts.
  
  ## What Changed
  
  - Added top-level `parent_thread_id` persistence on `SessionMeta` and
  runtime/session plumbing through `SessionConfiguredEvent`,
  `CodexSpawnArgs`, `SessionConfiguration`, `ThreadConfigSnapshot`,
  `TurnContext`, and `ModelClient`.
  - Made turn metadata, request headers, analytics, and subagent-start
  events read the separate runtime/top-level parent field instead of
  deriving general parent lineage from `SessionSource` or
  `forked_from_thread_id`.
  - Passed parent lineage separately at delegated subagent, review,
  guardian, agent-job, and multi-agent spawn construction sites;
  copied-history fork lineage remains derived only from `InitialHistory`.
  - Persisted and exposed parent lineage through rollout/thread-store
  projections and app-server v2 `Thread.parentThreadId`.
  - Updated app-server README text and regenerated app-server schema
  fixtures for the additive `parentThreadId` response field.

• Add cloud-managed config layer support (#24620)

  ## Summary
  
  PR 3 of 5 in the cloud-managed config client stack.
  
  Adds enterprise-managed cloud config as a first-class config layer
  source. The layer metadata is preserved through config loading,
  diagnostics, debug output, hook attribution, and app-server protocol
  surfaces.
  
  ## Details
  
  - Enterprise-managed config becomes a normal config layer source with
  backend-supplied `id` and display `name` attached for provenance.
  - These layers are designed to behave like non-file managed config: they
  can surface syntax/type diagnostics by layer name even though there is
  no physical config file.
  - Relative path settings are resolved from a stored config base so
  cloud-delivered config remains consistent with existing MDM-delivered
  config semantics.
  - Hook attribution distinguishes config-delivered hooks from
  requirements-delivered hooks via `HookSource::CloudManagedConfig`.
  - This remains pull-based and snapshot-oriented; the PR adds layer
  identity/diagnostics, not dynamic reload behavior.
  
  ## Validation
  
  Validated through the targeted stack checks after rebasing onto current
  `main`:
  
  - Rust crate tests for
  config/hooks/cloud-config/backend-client/app-server-protocol
  - Filtered `codex-core` and `codex-app-server` `cloud_config_bundle`
  tests
  - Python generated-file contract test
  - `cargo shear --deny-warnings`
  - Targeted `argument-comment-lint` for config/hooks

• [codex] Update remote connector suggestions (#25172)

  ## Summary
  
  - Use the session-loaded plugin app IDs as the source of connector
  suggestion candidates.
  - Remove the redundant plugin reload from
  `tool_suggest_connector_ids()`.
  - Add regression coverage for connectors declared by a loaded remote
  plugin, using the Databricks app case.
  
  ## Context
  
  Loaded remote plugins can declare app connector IDs in `.app.json`. The
  session-owned `PluginsManager` already loads those plugins and exposes
  their effective app IDs.
  
  The connector suggestion path was creating a separate `PluginsManager`
  and recomputing plugin app IDs. That new manager does not share the
  session manager’s remote installed plugin cache, so app IDs from loaded
  remote plugins were missing from connector suggestions.
  
  ## Fix
  
  Pass the already-loaded effective app IDs into connector suggestion
  generation and use them directly as the plugin-derived connector
  candidate set.
  
  Connector candidates are now built from:
  
  - App IDs declared by loaded plugins
  - Explicitly configured connector discoverables
  - Existing disabled-suggestion filtering
  
  This avoids a second plugin-manager lookup and keeps connector
  suggestions aligned with the plugins actually loaded for the turn.
  
  ## Behavior
  
  For example, when a plugin is loaded and its `.app.json` declares data
  apps, `list_available_plugins_to_install` can now return those data
  connectors.
  
  This does not create plugin suggestions from the plugin itself. Plugin
  suggestions still come from eligible uninstalled entries in the
  marketplace catalog and require existing matching/filtering rules.
  
  ## Validation
  
  - `just fmt`
  - Added regression coverage for a loaded-plugin connector ID appearing
  in discoverable tools
  - Attempted `just test -p codex-core`; the command exited unsuccessfully
  in the local test environment without useful failure detail captured in
  the run output

• Constrain Windows sandbox requirements (#23766)

  # Why
  
  Managed requirements can already constrain sandbox policy choices, but
  Windows sandbox implementation selection was still resolved
  independently from those requirements. That left the TUI able to
  continue through the unelevated fallback even when an organization wants
  to require the elevated Windows sandbox implementation.
  
  # What
  
  - Add `[windows].allowed_sandbox_implementations` requirements support
  for the Windows `elevated` and `unelevated` implementations.
  - Apply that allowlist during core config resolution so disallowed
  configured or feature-selected Windows sandbox implementations fall back
  to an allowed implementation with the existing requirements warning
  path.
  - Reuse the existing TUI Windows setup prompts to block disallowed
  unelevated continuation, keep required elevated setup in front of the
  user, and refuse to persist a TUI-selected Windows sandbox mode that
  requirements disallow.
  
  # Semantics
  
  | Allowed | Selected | Effective |
  | --- | --- | --- |
  | `["elevated"]` | `unelevated` / unset | `elevated` |
  | `["unelevated"]` | `elevated` / unset | `unelevated` |
  | `["elevated", "unelevated"]` | `elevated` | `elevated` |
  | `["elevated", "unelevated"]` | `unelevated` | `unelevated` |
  | `["elevated", "unelevated"]` | unset | `elevated` |
  
  Availability is handled by interactive setup surfaces after allowlist
  resolution. If the effective elevated implementation is not ready,
  elevated-only requirements block on setup. When unelevated is also
  allowed, the UI may offer the existing unelevated fallback.
  
  ## TUI Screens
  
  If elevated setup is not already complete:
  ```
    Your organization requires the default Codex agent sandbox to continue. Set it up to protect your files and control
    network access.
    Learn more <https://developers.openai.com/codex/windows>
  
  › 1. Set up default sandbox (requires Administrator permissions)
    2. Quit
  ```
  
  If admin setup fails under `["elevated"]`:
  ```
    Couldn't set up your sandbox with Administrator permissions
  
    Your organization requires the default sandbox before Codex can continue.
    Learn more <https://developers.openai.com/codex/windows>
  
  › 1. Try setting up admin sandbox again
    2. Quit
  ```
  
  # Next Steps
  
  
  - extend the requirements/readout surface, such as
  `configRequirements/read`, so clients can inspect the loaded
  `[windows].allowed_sandbox_implementations` requirement instead of
  inferring it from Windows setup state
  - consider extending `windowsSandbox/readiness` as well
  - update the App startup guide, setup flow, and banner surfaces so an
  elevated-only requirement omits any continue-unelevated escape hatch and
  blocks startup until a permitted implementation is ready;
  - preserve the existing unelevated fallback path when requirements allow
  it, including the `["unelevated"]` case where elevated is disallowed

• Filter plugin install suggestions by installed apps (#24996)

  ## Summary
  
  - Keep the original `TOOL_SUGGEST_DISCOVERABLE_PLUGIN_ALLOWLIST` as a
  fallback seed list, so users with no installed plugins still get initial
  install suggestions.
  - Allow additional install suggestions from trusted marketplaces:
  `openai-curated` and `openai-bundled`.
  - Require non-fallback, non-configured marketplace candidates to share
  `.app.json` connector IDs with already installed plugins.
  - Preserve explicit configured plugin discoverables as an override,
  while still omitting installed, disabled, and `NOT_AVAILABLE` plugins.
  
  ## Context
  
  `list_available_plugins_to_install` controls which plugins the model can
  trigger via `request_plugin_install`. We want a small starter set for
  empty/new users, but we also want installed workflow plugins to unlock
  relevant source plugins without maintaining every source plugin ID by
  hand.
  
  This keeps the legacy plugin ID allowlist only as the starter fallback.
  For everything else, the trusted marketplace is the candidate boundary,
  and installed app connector overlap is the relevance filter. For
  example, an installed Sales plugin can make HubSpot and Granola
  suggestible when those source plugins are in `openai-curated` and share
  Sales app connector IDs, while an unrelated test-source plugin with an
  app connector not declared by Sales stays hidden.
  
  ## Test Coverage
  
  - Empty/no-installed-plugin case: returns the fallback seed plugins from
  the original allowlist.
  - Installed-app expansion: returns non-fallback marketplace plugins only
  when their app connector IDs overlap with an installed plugin.
  - Sales workflow case: installed Sales declares HubSpot and Granola
  apps, so `hubspot@openai-curated` and `granola@openai-curated` are
  returned.
  - Sales negative case: `test-source@openai-curated` has an app connector
  not declared by Sales, so it is not returned.
  - Existing guardrails: installed plugins, disabled suggestions, and
  `NOT_AVAILABLE` plugins remain omitted; explicit configured
  discoverables still work as an override.
  
  ## Validation
  
  - `just fmt`
  - `just test -p codex-core plugins::discoverable::tests`
  - `just test -p codex-core` was attempted earlier, but current `main` /
  local env failed with unrelated existing failures around missing
  `test_stdio_server`, CLI/code-mode MCP tool setup, and
  unified_exec/shell snapshot flakes/timeouts. The touched discoverable
  tests pass.

• [codex] Require model for standalone web search (#25131)

  ## Why
  
  The standalone `/v1/alpha/search` request now requires a `model`, but
  the `web.run` extension currently omits it.
  
  Adds `model` to extension `ToolCall` invocation.
  
  Follow-up to #23823.
  
  ## What changed
  
  - Make `SearchRequest.model` required.
  - Expose the effective per-turn model on extension tool calls and pass
  it in standalone web-search requests.
  - Assert the model is forwarded in the app-server round-trip test.
  
  ## Testing
  
  - `just test -p codex-api -p codex-tools -p codex-web-search-extension

• thread-store: store permission profiles (#23165)

  ## Why
  
  `SandboxPolicy` is the legacy compatibility shape, but
  `codex-thread-store` still exposed it through `StoredThread`,
  `ThreadMetadataPatch`, and live metadata sync. That kept thread-store
  consumers tied to the legacy representation and meant richer permission
  profile data could not round-trip through thread metadata or cold
  rollout reconciliation.
  
  ## What Changed
  
  - Replaced thread-store `sandbox_policy` API fields with canonical
  `PermissionProfile` fields.
  - Persist new permission-profile metadata as canonical JSON in the
  existing SQLite metadata slot while continuing to read older legacy
  sandbox policy values.
  - Updated local, in-memory, live metadata sync, and rollout extraction
  paths to propagate `TurnContextItem::permission_profile()`.
  - Re-materialize legacy permission metadata against the final rollout
  cwd when rollout-derived metadata replaces stale SQLite summaries.
  - Updated affected app-server and core test constructors to build
  `PermissionProfile` values directly.
  
  ## Test Plan
  
  - `cargo test -p codex-state`
  - `cargo test -p codex-thread-store`
  - `cargo test -p codex-app-server

  code-mode cells.
  
  This moves cell lifecycle, callback delegation, termination, and
  shutdown behind a session abstraction, while continuing to use the
  existing in-process implementation, and the ability to implement an
  external process one behind this interface.
  
  A Codex session owns one `CodeModeSession`, which in turn owns its
  running cells and stored code-mode state. Each cell is represented to
  the caller as a `StartedCell`, exposing its cell ID and initial
  response.
  
  It also introduces a `CodeModeSessionDelegate` callback interface. A
  session uses the delegate to invoke nested host tools and emit
  notifications while a cell is running, allowing the runtime to
  communicate with its owning Codex session without depending directly on
  core turn handling.

• Add subagent lineage metadata for responsesapi (#24161)

  ## Why
  
  We recently added `forked_from_thread_id` which lets us trace where a
  thread's _context_ comes from, but we also want to understand subagent
  lineage (e.g. which parent thread spawned this subagent? what kind of
  subagent is it?) which is orthogonal.
  
  This PR adds `parent_thread_id` and `subagent_kind` to the
  `x-codex-turn-metadata` header sent to ResponsesAPI.
  
  ## What changed
  
  - Adds `parent_thread_id` and `subagent_kind` to core-owned
  `x-codex-turn-metadata`.
  - Restores persisted `SessionSource` and `ThreadSource` from resumed
  session metadata so cold-resumed subagent threads keep their lineage on
  later Responses API requests.
  - Centralizes parent-thread extraction on `SessionSource` /
  `SubAgentSource` and reuses it in the Responses client, analytics, agent
  control, and state parsing paths.
  - Extends reserved-key, git-enrichment, thread-spawn, and app-server v2
  metadata coverage for the new lineage fields.
  
  ## Verification
  
  - Not run locally per request.
  - Added focused coverage in `core/src/turn_metadata_tests.rs` and
  `app-server/tests/suite/v2/client_metadata.rs`.

• Add Windows sandbox provisioning setup command (#24831)

  ## Why
  
  Some Windows users do not have local admin access, so they cannot
  complete the elevated portion of the Windows sandbox setup when Codex
  first needs it. This adds an alpha provisioning path that an admin or IT
  deployment script can run ahead of time for the Codex user.
  
  The intended managed-deployment shape is:
  
  ```powershell
  codex sandbox setup --elevated --user "$env:COMPUTERNAME\Alice" --codex-home "C:\Users\Alice\.codex"
  ```
  
  `--elevated` is treated as the requested sandbox setup level, not as
  proof that the process is elevated. The Windows sandbox setup
  orchestration still checks that the caller is actually elevated before
  launching the helper without a UAC prompt.
  
  ## What changed
  
  - Added `codex sandbox setup --elevated` with explicit user selection
  via either `--current-user` or `--user ... --codex-home ...`.
  - Moved the CLI implementation into `cli/src/sandbox_setup.rs` instead
  of growing `cli/src/main.rs`.
  - Added a Windows sandbox `ProvisionOnly` helper mode that runs the
  elevation-required provisioning work without requiring a workspace cwd
  or runtime sandbox policy.
  - Reused the existing elevated helper path for creating/updating sandbox
  users, configuring firewall/WFP rules, and applying sandbox directory
  ACLs.
  - Persisted `windows.sandbox = "elevated"` into the target `CODEX_HOME`
  so the desktop app does not show the initial sandbox setup banner after
  pre-provisioning succeeds.
  
  ## Validation
  
  - `cargo fmt -p codex-windows-sandbox -p codex-core -p codex-cli`
  - `cargo test -p codex-cli sandbox_setup --target-dir
  target\sandbox-setup-check`
  - `cargo test -p codex-windows-sandbox
  payload_accepts_provision_only_mode --target-dir
  target\sandbox-setup-check`
  - `git diff --check`
  - Manual Windows alpha flow with a standard local user (`Mandi Lavida`):
  ran the new setup command from an admin shell, verified the target
  `.codex` contents, sandbox marker/secrets, ACLs, firewall rules, and
  desktop startup without the sandbox setup banner once experimental
  network proxy requirements were disabled.
  
  ## Notes
  
  This intentionally does not solve later elevated update coordination for
  IT-managed deployments. The setup command can still apply provisioning
  updates when run again, but a broader coordination/process story is out
  of scope for this alpha.

• Route extension image generation through the native image completion pipeline (#24972)

  ## Why
  
  The standalone `image_gen.imagegen` extension should behave like native
  image generation for artifact persistence and UI completion, while
  returning its save-location guidance as part of the tool result instead
  of injecting a developer message.
  
  ## What Changed
  
  - Added an image-generation completion hook for extension tools so core
  can persist generated images and emit the existing `ImageGeneration`
  lifecycle events.
  - Reused core image artifact persistence for extension output and
  removed extension-local save-path/file-writing logic.
  - Split shared image persistence from built-in finalization so native
  image generation keeps its existing developer-message instruction
  behavior.
  - Returned the generated image save-location instruction through the
  extension `FunctionCallOutput`, alongside the generated image input for
  model follow-up.
  - Preserved the existing image-generation event shape for current UI and
  replay compatibility.
  - Avoided cloning the full generated-image base64 payload when emitting
  the in-progress image item.
  - Removed dependencies no longer needed after moving persistence out of
  the extension crate.
  
  ## Fast Follow
  - Adjust the existing Extension API and add a general `TurnItem`
  finalization path for re-usability of code
  
  ## Validation
  
  - Ran `just fmt`.
  - Ran `just bazel-lock-update`.
  - Ran `just bazel-lock-check`.
  - Ran `just test -p codex-tools -p codex-extension-api -p
  codex-image-generation-extension`.
  - Ran `just test -p codex-core
  image_generation_publication_is_finalized_by_core`.
  - Ran `just test -p codex-core
  handle_output_item_done_records_image_save_history_message`.
  - Ran `just fix -p codex-tools -p codex-extension-api -p codex-core -p
  codex-image-generation-extension`.

• [codex] Wait for MCP readiness in core integration tests (#24964)

  Ensures MCP-backed `codex-core` integration tests exercise initialized
  servers instead of racing server startup.
  
  I've been idly investigating a few flakes and the failure modes are much
  more confusing when a tool call fails because of a failed server start
  than when the failed server start causes the test to fail directly.

• Move config document helpers into their own module (#25110)

  ## Why
  
  `core/src/config/edit.rs` owns the config edit state machine, but it
  also carried the TOML document helper code inline as a nested module.
  Moving those helpers into their own file keeps the edit orchestration
  easier to scan without changing the config persistence behavior.
  
  ## What changed
  
  - Moved the existing `document_helpers` module from
  `core/src/config/edit.rs` into
  `core/src/config/edit/document_helpers.rs`.
  - Added `mod document_helpers;` so the existing `pub(super)` helper API
  remains available to the rest of `config::edit`.
  
  ## Testing
  
  Not run; this is a refactor-only module extraction with no intended
  behavior change.

• [codex] Add model tool mode selector (#25031)

  ## Why
  Some models need to select their code-execution behavior through model
  catalog metadata. Models without that metadata must continue to follow
  the existing `CodeMode` and `CodeModeOnly` feature flags, including when
  a newer server sends an enum value this client does not recognize.
  
  ## What changed
  - add optional `ModelInfo.tool_mode` metadata with `direct`,
  `code_mode`, and `code_mode_only`
  - treat omitted and unknown wire values as `None`
  - resolve `None` from the existing feature flags
  - carry the resolved `ToolMode` directly on `TurnContext`, outside
  `Config`
  - use the resolved value for turn creation, model switches, review
  turns, tool planning, and code execution
  
  ## Coverage
  - add protocol coverage for omitted, known, and unknown enum values
  - add focused coverage for flag fallback and explicit metadata
  overriding feature flags
  - add core integration coverage that fetches remote model metadata
  through `/v1/models` and verifies the outbound `/responses` tools for
  explicit `direct` and `code_mode_only` selectors
  
  ## Stack
  - followed by #25032

• [codex] Improve built-in tool schema docs (#24794)

  ## Summary
  - Clarify default, omission, and bounded behavior across built-in tool
  schemas, including unified exec, classic shell, Code Mode exec/wait,
  multi-agent, agent job, MCP resource, image, goal, plan, tool_search,
  and test-sync fields.
  - Convert update_plan status to an enum and add short field descriptions
  where the schema previously relied on surrounding context.
  - Remove the dedicated permission-approval schema test and keep only
  updates to existing expected-spec tests.
  
  ## Validation
  - Ran `just fmt`.
  - Ran `git diff --check`.
  - Did not run clippy or tests, per request.

• Use inject_if_running for active goal steering (#24924)

  ## Why
  
  This PR is stacked on #24918, which moves goal steering onto
  source-labeled internal model context fragments. Active-turn goal
  steering should use the same running-turn injection path as other
  runtime steering, so those fragments enter the pending input queue as
  `ResponseItem`s through the existing
  [`Session::inject_if_running`](https://github.com/openai/codex/blob/8d6f6cdf69b055c27682e7cdea9caf72a3e2ee7f/codex-rs/core/src/session/inject.rs#L12-L27)
  behavior instead of through a goal-specific conversion wrapper.
  
  ## What Changed
  
  - Exposes a narrow `CodexThread::inject_if_running` bridge for callers
  that only hold a thread handle.
  - Changes `ext/goal` active-turn steering to pass `ResponseItem`s
  directly.
  - Builds goal steering prompts as contextual internal model context
  `ResponseItem`s before injecting them into the running turn.
  
  ## Testing
  
  Not run locally; PR metadata update only.

• Use internal model context fragments for goal steering (#24918)

  ## Why
  
  Goal steering is one form of runtime-owned model context, but the old
  `<goal_context>` wrapper made the contextual-fragment hiding path
  goal-specific. Using a source-labeled internal context fragment gives
  core and extensions a shared shape for hidden model steering while
  keeping those prompts out of visible turn history.
  
  The change also keeps legacy `<goal_context>` messages recognized as
  hidden contextual input so existing stored history does not start
  rendering old goal-steering prompts as user-visible turn items.
  
  ## What Changed
  
  - Replaces `GoalContext` with `InternalModelContextFragment` plus a
  validated `InternalContextSource`.
  - Renders goal steering as `<codex_internal_context
  source="goal">...</codex_internal_context>`.
  - Updates core goal steering and `ext/goal` steering to inject the new
  internal-context fragment.
  - Updates contextual-fragment, event-mapping, goal, and session tests
  for the new wrapper.
  
  ## Test Coverage
  
  - Adds coverage for detecting the new internal model context fragment.
  - Preserves coverage for hiding legacy `<goal_context>` fragments.
  - Verifies invalid internal context sources are rejected and arbitrary
  context tags are not hidden.
  - Updates goal steering/session assertions to expect the new
  `source="goal"` wrapper.

• fix: preserve deny-read sandboxing for safe commands (#23943)

  ## Why
  
  Permission profiles can mark filesystem entries as unreadable with
  `deny` rules, including glob patterns. Several shell execution paths
  treated known-safe commands or execpolicy `allow` rules as sufficient to
  run outside the filesystem sandbox. That is not valid for read-capable
  commands: for example, `cat` or `ls` may be reasonable to allow
  generally, but dropping the sandbox would also drop deny-read
  constraints such as `**/*.env`.
  
  ## What changed
  
  - Added a shared check that treats active deny-read restrictions as
  incompatible with unsandboxed execution.
  - Kept first-attempt execution sandboxed for explicit escalation and
  execpolicy allow bypasses when deny-read entries are present.
  - Prevented no-sandbox retry after a sandbox denial when the active
  filesystem policy contains deny-read entries.
  - Updated the zsh-fork execve path so prefix-rule `allow` decisions
  continue inside the current sandbox when deny-read restrictions are
  active.
  
  ## Verification
  
  - `cargo test -p codex-core tools::sandboxing::tests`
  - `cargo test -p codex-core
  tools::runtimes::shell::unix_escalation::tests`
  - `cargo test -p codex-core

• fix(config): use deny for Unix socket permissions (#24970)

  ## Why
  
  Unix socket permissions still accepted and displayed `"none"` while file
  permissions use the clearer `"deny"` spelling. This keeps network Unix
  socket policy vocabulary consistent with filesystem policy vocabulary.
  
  ## What changed
  
  - Replace the Unix socket permission variant and serialized spelling
  from `none` to `deny` across config, feature configuration, and network
  proxy types.
  - Update app-server v2 serialization, TUI debug output, focused tests,
  and generated schemas to expose `"deny"`.
  - Add coverage for denied Unix socket entries in managed requirements
  and profile overlay behavior.
  
  ## Security
  
  This is a vocabulary change for explicit Unix socket rejection, not a
  network access expansion. Denied entries continue to be omitted from the
  effective allowlist.
  
  ## Validation
  
  - `just fmt`
  - `just write-config-schema`

• windows-sandbox: pass workspace roots to runner (#24108)

  ## Why
  
  #23813 switches the Windows sandbox runner path to `PermissionProfile`,
  but it still left one runtime anchor for resolving symbolic
  `:workspace_roots` entries. That is not enough once a turn has multiple
  effective workspace roots: exact entries and deny globs under
  `:workspace_roots` need to be materialized for every runtime root before
  the command runner chooses token mode or builds ACL plans.
  
  ## What Changed
  
  - Replaces the Windows runner/setup `permission_profile_cwd` plumbing
  with `workspace_roots: Vec<AbsolutePathBuf>`.
  - Resolves Windows-local `PermissionProfile` data with
  `materialize_project_roots_with_workspace_roots(...)` instead of the
  single-cwd helper.
  - Threads `Config::effective_workspace_roots()` through core execution,
  unified exec, TUI setup/read-grant flows, app-server setup, app-server
  `command/exec`, and `debug sandbox` on Windows.
  - Preserves those workspace roots through the zsh-fork escalation
  executor instead of rebuilding them from `sandbox_policy_cwd`.
  - Makes `ExecRequest::new(...)` and the remaining
  `build_exec_request(...)` helper path take
  `windows_sandbox_workspace_roots` explicitly so new call sites cannot
  silently fall back to `vec![cwd]`.
  - Clarifies the `debug sandbox` non-Windows comment: remaining
  cwd-dependent resolution still uses `sandbox_policy_cwd`, while
  `:workspace_roots` entries are already materialized from config roots.
  - Updates elevated runner IPC `SpawnRequest` to send `workspace_roots`
  and bumps the framed IPC protocol version to `3` for the payload shape
  change.
  - Adds Windows-local resolver coverage for expanding exact and glob
  `:workspace_roots` entries across multiple roots, plus core helper
  coverage proving explicit roots are preserved.
  
  ## Verification
  
  - `cargo check -p codex-windows-sandbox -p codex-core -p codex-tui -p
  codex-cli -p codex-app-server`
  - `cargo test -p codex-windows-sandbox`
  - `cargo test -p codex-core windows_sandbox`
  - `cargo test -p codex-core unix_escalation`
  - `cargo test -p codex-app-server windows_sandbox`
  - `cargo test -p codex-tui windows_sandbox`
  - `cargo test -p codex-cli debug_sandbox`
  - `just test -p codex-core unified_exec`
  - `just test -p codex-core

  - `env -u CODEX_NETWORK_PROXY_ACTIVE -u

  command_exec`
  - `just test -p codex-windows-sandbox`
  - `just test -p codex-exec sandbox`
  - `just fix -p codex-core -p codex-app-server -p codex-windows-sandbox`
  
  A local macOS cross-check with `cargo check --target
  x86_64-pc-windows-msvc ...` did not reach crate Rust code because native
  dependencies require Windows SDK headers (`windows.h` / `assert.h`) in
  this environment; Windows CI remains the real target validation.
  
  Two local targeted filters compile but do not run assertions on macOS:
  `env -u CODEX_NETWORK_PROXY_ACTIVE -u CODEX_NETWORK_ALLOW_LOCAL_BINDING
  just test -p codex-app-server --lib command_exec_processor` matched zero
  tests, and `just test -p codex-linux-sandbox landlock` matched zero
  tests because the landlock suite is Linux-only.
