• Split plugin install discovery into list and request tools (#23372)

  ## Summary
  - Add `list_available_plugins_to_install` as the inventory step for
  plugin and connector install suggestions.
  - Slim `request_plugin_install` so it only handles the actual
  elicitation, instead of carrying the full discoverable list in its
  prompt.
  - Emit send-time telemetry when an install elicitation is dispatched,
  including requested tool identity in the event payload.
  - Emit install-result telemetry through `SessionTelemetry`, including
  tool type, user response action, and completion status.
  - Update registration and tests to cover the new two-step flow while
  keeping the existing `tool_suggest` feature gate unchanged.
  
  ## Testing
  - `just fmt`
  - `cargo test -p codex-tools`
  - `cargo test -p codex-core request_plugin_install`
  - `cargo test -p codex-core list_available_plugins_to_install`

• Add SubagentStart hook (#22782)

  # What
  
  `SubagentStart` runs once when Codex creates a thread-spawned subagent,
  before that child sends its first model request. Thread-spawned
  subagents use `SubagentStart` instead of the normal root-agent
  `SessionStart` hook.
  
  Configured handlers match on the subagent `agent_type`, using the same
  value passed to `spawn_agent`. When no agent type is specified, Codex
  uses the default agent type.
  
  Hook input includes the normal session-start fields plus:
  
  - `agent_id`: the child thread id.
  - `agent_type`: the resolved subagent type.
  
  `SubagentStart` may return `hookSpecificOutput.additionalContext`. That
  context is added to the child conversation before the first model
  request.
  
  # Lifecycle Scope
  
  Only thread-spawned subagents run `SubagentStart`.
  
  Internal/system subagents such as Review, Compact, MemoryConsolidation,
  and Other do not run normal `SessionStart` hooks and do not run
  `SubagentStart`. This avoids exposing synthetic matcher labels for
  internal implementation paths.
  
  Also the `SessionStart` hook no longer fires for subagents, this matches
  behavior with other coding agents' implementation
  
  # Stack
  
  1. This PR: add `SubagentStart`.
  2. #22873: add `SubagentStop`.
  3. #22882: add subagent identity to normal hook inputs.

• Make deny canonical for filesystem permission entries (#23493)

  ## Why
  Filesystem permission profiles used `none` for deny-read entries, which
  is less direct than the action the entry actually represents. This
  change makes `deny` the canonical filesystem permission spelling while
  preserving compatibility for older configs that still send `none`.
  
  ## What changed
  - rename `FileSystemAccessMode::None` to `Deny`
  - serialize and generate schemas with `deny` as the canonical value
  - retain `none` only as a legacy input alias for temporary config
  compatibility
  - update filesystem glob diagnostics and regression coverage to use the
  canonical spelling
  - refresh config and app-server schema fixtures to match the new wire
  shape
  
  ## Validation
  - `cargo test -p codex-protocol`
  - `cargo test -p codex-app-server-protocol`
  - `cargo test -p codex-core config_toml_deserializes_permission_profiles
  --lib`
  - `cargo test -p codex-core
  read_write_glob_patterns_still_reject_non_subpath_globs --lib`
  
  Earlier in the session, a broad `cargo test -p codex-core` run reached
  unrelated pre-existing failures in timing/snapshot/git-info tests under
  this environment; the targeted surfaces touched by this PR passed
  cleanly.

• chore: namespace v1 sub-agent tools (#23475)

  ## Why
  
  The v1 sub-agent tools are a single tool family, but they were exposed
  as separate flat function tools. This makes the model-visible surface
  less clearly grouped and leaves the legacy names in the same flat
  namespace as newer agent tooling.
  
  ## What
  
  - Wraps the v1 `spawn_agent`, `send_input`, `resume_agent`,
  `wait_agent`, and `close_agent` specs in the `multi_agent_v1` namespace.
  - Registers the corresponding handlers with namespaced runtime tool
  names.
  - Updates tool-planning, deferred tool search, and sub-agent
  notification tests to assert the namespace shape and child `spawn_agent`
  lookup.
  
  ## Verification
  
  - Updated `codex-core` coverage for the v1 multi-agent tool plan,
  deferred tool search output, and sub-agent tool descriptions.

• Defer v1 multi-agent tools behind tool search (#23144)

  Summary: defer v1 multi-agent tools when tool_search and namespace tools
  are available; keep concise searchable descriptions and move the v1
  usage guidance into developer instructions; add targeted coverage.
  Testing: not run per request; ran just fmt.

• Add body_after_prefix auto-compact token limit scope (#22870)

  ## Why
  
  `model_auto_compact_token_limit` has only been able to budget the full
  active context. That makes it hard to set a small "growth since
  compaction" budget for sessions that preserve a large carried window
  prefix: the preserved prefix can consume the whole budget and force
  immediate repeated compaction.
  
  This PR adds an opt-in `body_after_prefix` scope so callers can apply
  `model_auto_compact_token_limit` to sampled output and later growth
  after the current carried prefix, while still forcing compaction before
  the full model context window is exhausted.
  
  ## What changed
  
  - Adds `AutoCompactTokenLimitScope` with the existing `total` behavior
  as the default and a new `body_after_prefix` mode:
  [`config_types.rs`](https://github.com/openai/codex/blob/973806b1cb35792555bead994cb3ed94656eb171/codex-rs/protocol/src/config_types.rs#L24-L37).
  - Threads `model_auto_compact_token_limit_scope` through config loading,
  `Config`, `core-api`, and app-server v2 schema/TypeScript generation.
  - Records the first observed input-token count for a `body_after_prefix`
  compaction window and uses it as the baseline when deciding whether the
  scoped auto-compaction budget is exhausted:
  [`turn.rs`](https://github.com/openai/codex/blob/973806b1cb35792555bead994cb3ed94656eb171/codex-rs/core/src/session/turn.rs#L743-L781).
  - Keeps a hard context-window cap in `body_after_prefix`, so scoped
  budgeting cannot let the active context overrun the usable window.
  
  ## Verification
  
  Added compact-suite coverage for the two key behaviors:
  `body_after_prefix` does not re-compact just because the carried prefix
  is larger than the scoped budget, and it still compacts when the total
  active context reaches the configured context window:
  [`compact.rs`](https://github.com/openai/codex/blob/973806b1cb35792555bead994cb3ed94656eb171/codex-rs/core/tests/suite/compact.rs#L3003-L3128).

• Remove explicit connector tool undeferral (#23390)

  ## Summary
  - remove the explicit-connector carveout that kept mentioned app tools
  directly exposed instead of deferred
  - keep the surviving explicit-mention reconstruction only for analytics,

• [5 of 7] Replace OverrideTurnContext with ThreadSettings (#22508)

  **Stack position:** [5 of 7]
  
  ## Summary
  
  This PR adds `Op::ThreadSettings`, a queued settings-only update
  mechanism for changing stored thread settings without starting a new
  turn. It also removes the legacy `Op::OverrideTurnContext` in the same
  layer, so reviewers can see the replacement and deletion together.
  
  ## Changes
  
  - Add `Op::ThreadSettings` for settings-only queued updates.
  - Emit `ThreadSettingsApplied` with the effective thread settings
  snapshot after core applies an update.
  - Route settings-only updates through the same submission queue as user
  input.
  - Migrate remaining `OverrideTurnContext` tests and callers to the
  queued `Op::ThreadSettings` path.
  - Delete `Op::OverrideTurnContext` from the core protocol and submission
  loop.
  
  This stack addresses #20656 and #22090.

• [1 of 7] Add thread settings to UserInput (#23080)

  **Stack position:** [1 of 7]
  
  ## Summary
  
  The first three PRs in this stack are a cleanup pass before the actual
  thread settings API work.
  
  Today, core has several overlapping "user input" ops: `UserInput`,
  `UserInputWithTurnContext`, and `UserTurn`. They differ mostly in how
  much next-turn state they carry, which makes the later queued thread
  settings update harder to reason about and review.
  
  This PR starts that cleanup by adding the shared
  `ThreadSettingsOverrides` payload and allowing `Op::UserInput` to carry
  it. Existing variants remain in place here, so this layer is mostly a
  behavior-preserving API shape change plus mechanical constructor
  updates.
  
  ## End State After PR3
  
  By the end of PR3, `Op::UserInput` is the only "user input" core op. It
  can carry optional thread settings overrides for callers that need to
  update stored defaults with a turn, while callers without updates use
  empty settings. `Op::UserInputWithTurnContext` and `Op::UserTurn` are
  deleted.
  
  ## End State After PR5
  
  By the end of PR5, core will have only two ops for this area:
  
  - `Op::UserInput` for user-input-bearing submissions.
  - `Op::ThreadSettings` for settings-only updates.

• Remove ToolSearch feature toggle (#23389)

  ## Summary
  - mark `ToolSearch` as removed and ignore stale config writes for its
  legacy key
  - make search tool exposure depend only on model capability, not a
  feature toggle
  - remove app-server enablement support and prune now-obsolete test
  coverage/setup
  
  ## Verification
  - `cargo test -p codex-features`
  - `cargo test -p codex-tools`
  - `cargo test -p codex-core search_tool_requires_model_capability`
  - `cargo test -p codex-app-server experimental_feature_enablement_set_`
  
  ## Notes
  - This keeps the legacy config key as a no-op for compatibility while
  removing the ability to toggle the behavior off cleanly.
  - No developer-facing docs update outside the touched app-server README
  was needed.

• [codex] Trim unused TurnContextItem fields (#22709)

  ## Why
  
  `TurnContextItem` is the durable baseline used to reconstruct context
  diffs across resume/fork. Most of the old persisted-only fields on it
  are no longer read, so keeping them in rollout snapshots adds schema
  surface and state that can drift without affecting reconstruction.
  
  `summary` is the exception: older Codex versions require it to
  deserialize `turn_context` records, so keep writing a default
  compatibility value until that schema surface can be removed safely.
  
  ## What changed
  
  - Removed the unused persisted fields from `TurnContextItem`: trace ids,
  user/developer instructions, output schema, and truncation policy.
  - Kept `summary` with a compatibility comment and made
  `TurnContext::to_turn_context_item` write `ReasoningSummary::Auto`
  instead of live turn state.
  - Updated rollout/context reconstruction fixtures for the retained
  summary field.
  
  ## Verification
  
  - `cargo test -p codex-protocol --lib turn_context_item`
  - `cargo test -p codex-rollout
  resume_candidate_matches_cwd_reads_latest_turn_context`

• [codex] Remove legacy shell output formatting paths (#22706)

  ## Why
  
  The client and tool pipeline still carried compatibility code for legacy
  structured shell output. Current shell and apply_patch responses are
  already plain text for model consumption, so keeping a
  JSON-serialization path plus shell-item rewrite logic makes the request
  formatter and tests preserve a format we do not need anymore.
  
  ## What Changed
  
  - Removed the client-side shell output rewrite from
  `core/src/client_common.rs`.
  - Removed the structured exec-output formatter and the shell `freeform`
  switch so tool emitters use one model-facing formatter.
  - Collapsed apply_patch/shell serialization tests around the remaining
  plain-text output expectations and removed duplicate one-variant
  parameterized cases.
  - Kept the `ApplyPatchModelOutput::ShellCommandViaHeredoc` compatibility
  input shape, but no longer treats it as a separate output-format mode.
  
  ## Validation
  
  - `cargo test -p codex-core client_common`
  - `cargo test -p codex-core shell_serialization`
  - `cargo test -p codex-core apply_patch_cli`
  - `just fix -p codex-core`
  
  ## Documentation
  
  No external Codex documentation update is needed.

• test: reduce core sandbox policy test setup (#23036)

  ## Why
  
  `SandboxPolicy` is a legacy compatibility shape, but several core tests
  still used it for ordinary turn setup even when the runtime path now
  carries `PermissionProfile`. With the first cleanup PR merged, this
  follow-up trims more core test scaffolding so remaining `SandboxPolicy`
  matches are easier to classify as production compatibility,
  legacy-boundary coverage, or explicit conversion tests.
  
  ## What Changed
  
  - Updated apply-patch handler and runtime tests to pass
  `PermissionProfile` directly.
  - Changed sandboxing test helpers to build permission profiles without
  first creating `SandboxPolicy` values.
  - Converted request-permissions integration turns to pass
  `PermissionProfile` through the test helper, leaving legacy sandbox
  projection at the `Op::UserTurn` boundary.
  - Converted unified exec integration helpers and direct turn submissions
  to use `PermissionProfile` values instead of `SandboxPolicy` setup.
  - Removed now-unused `SandboxPolicy` imports from the touched core
  tests.
  
  ## Test Plan
  
  - `just fmt`
  - `cargo test -p codex-core --lib tools::sandboxing::tests`
  - `cargo test -p codex-core --lib tools::runtimes::apply_patch::tests`
  - `cargo test -p codex-core --lib tools::handlers::apply_patch::tests`

• multiagent: trim model-visible description, cap to 5 models (#23069)

  ## Why
  
  The `spawn_agent` model override guidance is uncapped and bloating
  context. We need to trim down each entry and cap total entries.
  
  picked 5 as cap, we can change
  
  ## What changed
  
  - Cap the model override summaries shown in `spawn_agent` to the first 5
  picker-visible models, preserving the existing priority ordering from
  the models manager.
  - Condense each rendered entry to the actionable pieces the model needs:
    - use the model slug as the label
    - render compact reasoning effort lists with the default marked inline
  - render only service tier IDs, and omit the clause when no tiers are
  available
  - Update coverage so the compact formatter shape and the top-5 cap are
  exercised, and keep the end-to-end request assertion aligned with real
  model metadata.
  
  ## Example
  
  Before:
  
  `- gpt-5.4 ('gpt-5.4\'): Strong model for everyday coding. Default
  reasoning effort: medium. Supported reasoning efforts: low (Fast
  responses with lighter reasoning), medium (Balances speed and reasoning
  depth for everyday tasks), high (Greater reasoning depth for complex
  problems), xhigh (Extra high reasoning depth for complex problems).
  Supported service tiers: priority (Fast: 1.5x speed, increased usage).`
  
  After:
  
  `- 'gpt-5.4': Strong model for everyday coding. Reasoning efforts: low,
  medium (default), high, xhigh. Service tiers: priority.`

• test: construct permission profiles directly (#23030)

  ## Why
  
  `SandboxPolicy` is now a legacy compatibility shape, but several tests
  still built a `SandboxPolicy` only to immediately convert it into
  `PermissionProfile` for APIs that already accept canonical runtime
  permissions. Those detours make it harder to audit where legacy sandbox
  policy is still required, because boundary-only usages are mixed
  together with ordinary test setup.
  
  ## What Changed
  
  - Updated tests in `codex-core`, `codex-exec`, `codex-analytics`, and
  `codex-config` to construct `PermissionProfile` values directly when the
  code under test takes a permission profile.
  - Changed exec-policy, request-permissions, session, and sandbox test
  helpers to pass `PermissionProfile` through instead of converting from
  `SandboxPolicy` internally.
  - Left `SandboxPolicy` in place where tests are explicitly exercising
  legacy compatibility or request/response boundaries.
  
  ## Test Plan
  
  - `cargo test -p codex-analytics -p codex-config`
  - `cargo test -p codex-core --lib safety::tests`
  - `cargo test -p codex-core --lib exec_policy::tests::`
  - `cargo test -p codex-core --lib exec::tests`
  - `cargo test -p codex-core --lib guardian_review_session_config`
  - `cargo test -p codex-core --lib tools::network_approval::tests`
  - `cargo test -p codex-core --lib

• Preserve image detail in app-server inputs (#20693)

  ## Summary
  
  - Add optional image detail to user image inputs across core, app-server
  v2, thread history/event mapping, and the generated app-server
  schemas/types.
  - Preserve requested detail when serializing Responses image inputs:
  omitted detail stays on the existing `high` default, while explicit
  `original` keeps local images on the original-resolution path.
  - Support `high`/`original` consistently for tool image outputs,
  including MCP `codex/imageDetail`, code-mode image helpers, and
  `view_image`.

• Run compact hooks for remote compaction v2 (#22828)

  ## Why
  
  Remote compaction v2 is the `/responses` implementation of
  session-history compaction, but it still needs to preserve the
  observable contract of the legacy `/responses/compact` path. In
  particular, users and integrations that rely on `PreCompact` and
  `PostCompact` hooks should not see different behavior when
  `remote_compaction_v2` is enabled.
  
  ## What Changed
  
  - Runs `PreCompact` before issuing the remote compaction v2 request,
  including `Interrupted` analytics when a pre-hook stops execution.
  - Runs `PostCompact` after a successful v2 compaction and aborts the
  turn if the post-hook stops execution.
  - Adds `compact_remote_parity` coverage that compares legacy and v2
  compaction across manual transcript shapes, automatic pre-turn
  compaction, automatic mid-turn compaction, hook payloads, replacement
  history, follow-up request payloads, and API-key `service_tier=fast`
  behavior.
  - Registers the new parity suite under `core/tests/suite`.
  
  Relevant code:
  
  -

  ## Verification
  
  - Added `core/tests/suite/compact_remote_parity.rs` to assert parity
  between legacy remote compaction and remote compaction v2 for the

  - Existing `compact_remote_v2` unit coverage still exercises v2
  replacement-history retention and compaction-output collection.

• [codex] Use compaction_trigger item for remote compaction v2 (#22809)

  ## Why
  
  Remote compaction v2 was still using `context_compaction` as both the
  request trigger and the compacted output shape. The Responses API now
  has the landed contract for this flow: Codex sends a dedicated `{
  "type": "compaction_trigger" }` input item, and the backend returns the
  standard `compaction` output item with encrypted content.
  
  This aligns the v2 path with that wire contract while preserving the
  existing local compacted-history post-processing behavior.
  
  ## What changed
  
  - Add `ResponseItem::CompactionTrigger` and regenerate the app-server
  protocol schema fixtures.
  - Send `compaction_trigger` from `remote_compaction_v2` instead of a
  payload-less `context_compaction`.
  - Collect exactly one backend `compaction` output item, then reuse the
  existing compacted-history rebuilding path.
  - Treat the trigger item as a transient request marker rather than model
  output or persisted rollout/memory content.
  
  ## Verification
  
  - `cargo test -p codex-protocol compaction_trigger`
  - `cargo test -p codex-core remote_compact_v2`
  - `cargo test -p codex-core compact_remote_v2`
  - `cargo test -p codex-core
  responses_websocket_sends_response_processed_after_remote_compaction_v2`
  - `just write-app-server-schema`
  - `cargo test -p codex-app-server-protocol schema_fixtures`

• app-server: use permission ids and runtime workspace roots (#22611)

  ## Why
  
  This PR builds on [#22610](https://github.com/openai/codex/pull/22610)
  and is the app-server side of the migration from mutable per-turn
  `SandboxPolicy` replacement toward selecting immutable permission
  profiles by id plus mutable runtime workspace roots.
  
  Once permission profiles can carry their own immutable
  `workspace_roots`, app-server no longer needs to mutate the selected
  `PermissionProfile` just to represent thread-specific filesystem
  context. The mutable part now lives on the thread as explicit
  `runtimeWorkspaceRoots`, while `:workspace_roots` remains symbolic until
  the sandbox is realized for a turn.
  
  ## What Changed
  
  - Replaced the v2 permission-selection wrapper surface with plain
  profile ids for `thread/start`, `thread/resume`, `thread/fork`, and
  `turn/start`.
  - Removed the API surface for profile modifications
  (`PermissionProfileSelectionParams`,
  `PermissionProfileModificationParams`,
  `ActivePermissionProfileModification`).
  - Added experimental `runtimeWorkspaceRoots` fields to the thread
  lifecycle and turn-start APIs.
  - Threaded runtime workspace roots through core session/thread
  snapshots, turn overrides, app-server request handling, and command
  execution permission resolution.
  - Kept session permission state symbolic so later runtime root updates
  and cwd-only implicit-root retargeting rebind `:workspace_roots`
  correctly.
  - Updated the embedded clients just enough to send and restore the new
  thread state.
  - Refreshed the generated schema/TypeScript artifacts and the app-server
  README to match the new contract.
  
  ## Verification
  
  Targeted coverage for this layer lives in:
  
  - `codex-rs/app-server-protocol/src/protocol/v2/tests.rs`
  - `codex-rs/app-server/tests/suite/v2/thread_start.rs`
  - `codex-rs/app-server/tests/suite/v2/thread_resume.rs`
  - `codex-rs/app-server/tests/suite/v2/turn_start.rs`
  - `codex-rs/core/src/session/tests.rs`
  
  The key regression checks exercise that:
  
  - `runtimeWorkspaceRoots` resolve against the effective cwd on thread
  start.
  - Profile-declared workspace roots are excluded from the runtime
  workspace roots returned by app-server.
  - A turn-level runtime workspace-root update persists onto the thread
  and is returned by `thread/resume`.
  - A named permission profile selected on one turn remains symbolic so a
  later runtime-root-only turn update changes the actual sandbox writes.
  - A cwd-only turn update retargets the implicit runtime cwd root while
  preserving additional runtime roots.
  - The protocol fixtures and generated client artifacts stay in sync with
  the string-based permission selection contract.

• Stabilize compact rollback follow-up test (#22303)

  ## Summary
  - add the missing response.created event to the mocked empty follow-up
  response in the compact rollback test
  - keep the fix scoped to the flaky mocked stream shape, without
  increasing timeouts
  
  ## Recent flakes on main
  - `snapshot_rollback_followup_turn_trims_context_updates` failed in
  `rust-ci-full` on `main` in the Ubuntu remote test job on 2026-05-14:
  https://github.com/openai/codex/actions/runs/25891434395/job/76095284830
  - The same `compact_resume_fork` suite also failed recently on `main`
  with `snapshot_rollback_past_compaction_replays_append_only_history`,
  which has the same mocked Responses stream shape sensitivity this PR is
  tightening:

• Add user_input_requested_during_turn to MCP turn metadata (#22237)

  ## Why
  - Similar change as https://github.com/openai/codex/pull/21219
  - Without change: MCP tool calls receive
  `_meta["x-codex-turn-metadata"]` with various key values.
  - Issue: MCP servers currently do not know if user input was requested
  during the turn (Ex: Model decides to prompt the user for approval
  mid-turn before making a possibly risky tool call). MCP servers may want
  to know this when tracking latency metrics because these instances are
  inflated.
  
  ## What Changed
  - With change: MCP turn metadata now includes
  `user_input_requested_during_turn` when a model-visible
  `request_user_input` call happened earlier in the turn, propagated in
  `_meta["x-codex-turn-metadata"]`.
  - `mark_turn_user_input_requested()` is called when user input is
  requested through either MCP elicitation (`mcp.rs`) or the
  `request_user_input` tool (`mod.rs`).
  - MCP tool call `_meta` is now built immediately before execution
  (`mcp_tool_call.rs`) so user input requested earlier in the same turn,
  including within the same tool call via elicitation, is reflected in the
  metadata.
  - Normal `/responses` turn metadata headers are unchanged.
  
  ## Verification
  - `codex-rs/core/src/session/mcp_tests.rs`
  - `codex-rs/core/src/tools/handlers/request_user_input_tests.rs`
  - `codex-rs/core/src/turn_metadata_tests.rs`
  - `codex-rs/core/tests/suite/search_tool.rs`

• permissions: support workspace roots in profiles (#22610)

  ## Why
  
  This is the configuration/model half of the alternative permissions
  migration we discussed as a comparison point for
  [#22401](https://github.com/openai/codex/pull/22401) and
  [#22402](https://github.com/openai/codex/pull/22402).
  
  The old `workspace-write` model mixes three concerns that we want to
  keep separate:
  - reusable profile rules that should stay immutable once selected
  - user/runtime workspace roots from `cwd`, `--add-dir`, and legacy
  workspace-write config
  - internal Codex writable roots such as memories, which should not be
  shown as user workspace roots
  
  This PR gives permission profiles first-class `workspace_roots` so users
  can opt multiple repositories into the same `:workspace_roots` rules
  without using broad absolute-path write grants. It also starts
  separating the raw selected profile from the effective runtime profile
  by making `Permissions` expose explicit accessors instead of public
  mutable fields.
  
  A representative `config.toml` looks like this:
  
  ```toml
  default_permissions = "dev"
  
  [permissions.dev.workspace_roots]
  "~/code/openai" = true
  "~/code/developers-website" = true
  
  [permissions.dev.filesystem.":workspace_roots"]
  "." = "write"
  ".codex" = "read"
  ".git" = "read"
  ".vscode" = "read"
  ```
  
  If Codex starts in `~/code/codex` with that profile selected, the
  effective workspace-root set becomes:
  - `~/code/codex` from the runtime `cwd`
  - `~/code/openai` from the profile
  - `~/code/developers-website` from the profile
  
  The `:workspace_roots` rules are materialized across each root, so
  `.git`, `.codex`, and `.vscode` stay scoped the same way everywhere.
  Runtime additions such as `--add-dir` can still layer on later stack
  entries without mutating the selected profile.
  
  ## Stack Shape
  
  This PR intentionally stops before the profile-identity cleanup in
  [#22683](https://github.com/openai/codex/pull/22683) so the base review
  stays focused on config loading, workspace-root materialization, and
  compatibility with legacy `workspace-write`.
  
  The representation in this PR is therefore transitional: `Permissions`
  carries enough state to distinguish the raw constrained profile from the
  effective runtime profile, and there are still call sites that must keep
  the active profile identity and constrained profile value in sync. The
  follow-up PR replaces that with a single resolved profile state
  (`ResolvedPermissionProfile` / `PermissionProfileState`) that keeps the
  profile id, immutable `PermissionProfile`, and profile-declared
  workspace roots together. That follow-up removes APIs such as
  `set_constrained_permission_profile_with_active_profile()` where
  separate arguments could drift out of sync.
  
  Downstream PRs then build on this base to switch app-server turn updates
  to profile ids plus runtime workspace roots and to finish the
  user-visible summary behavior. Reviewers should judge this PR as the
  workspace-roots foundation, not as the final in-memory shape of selected
  permission profiles.
  
  ## Review Guide
  
  Suggested review order:
  
  1. Start with `codex-rs/core/src/config/mod.rs`.
  This is the main shape change in the base slice. `Permissions` now
  stores a private raw `Constrained<PermissionProfile>` plus runtime
  `workspace_roots`. Callers use `permission_profile()` when they need the
  raw constrained value and `effective_permission_profile()` when they
  need a materialized runtime profile. As noted above,
  [#22683](https://github.com/openai/codex/pull/22683) replaces this
  transitional shape with a resolved profile state that keeps identity and
  profile data together.
  
  2. Review `codex-rs/config/src/permissions_toml.rs` and
  `codex-rs/core/src/config/permissions.rs`.
  These add `[permissions.<id>.workspace_roots]`, resolve enabled entries
  relative to the policy cwd, and keep `:workspace_roots` deny-read glob
  patterns symbolic until the actual roots are known.
  
  3. Review `codex-rs/protocol/src/permissions.rs` and
  `codex-rs/protocol/src/models.rs`.
  These add the policy/profile materialization helpers that expand exact
  `:workspace_roots` entries and scoped deny-read globs over every
  workspace root. This is also where `ActivePermissionProfileModification`
  is removed from the core model.
  
  4. Review the legacy bridge in
  `Config::load_from_base_config_with_overrides` and
  `Config::set_legacy_sandbox_policy`.
  This is where legacy `workspace-write` roots become runtime workspace
  roots, while Codex internal writable roots stay internal and do not
  appear as user-facing workspace roots.
  
  5. Then skim downstream call sites.
  The interesting pattern is raw-vs-effective access: state/proxy/bwrap
  paths keep the raw constrained profile, while execution, summaries, and
  user-visible status use the effective profile and workspace-root list.
  
  ## What Changed
  
  - added `[permissions.<id>.workspace_roots]` to the config model and
  schema
  - added runtime `workspace_roots` state to `Config`/`Permissions` and
  `ConfigOverrides`
  - made `Permissions` profile fields private and replaced direct mutation
  with accessors/setters
  - added `PermissionProfile` and `FileSystemSandboxPolicy` helpers for
  materializing `:workspace_roots` exact paths and deny-read globs across
  all roots
  - moved legacy additional writable roots into runtime workspace-root
  state instead of active profile modifications
  - removed `ActivePermissionProfileModification` and its app-server
  protocol/schema export
  - updated sandbox/status summary paths so internal writable roots are
  not reported as user workspace roots
  
  ## Verification Strategy
  
  The targeted tests cover the behavior at the layers where regressions
  are most likely:
  - `codex-rs/core/src/config/config_tests.rs` verifies config loading,
  legacy workspace-root seeding, effective profile materialization, and
  memory-root handling.
  - `codex-rs/core/src/config/permissions_tests.rs` verifies profile
  `workspace_roots` parsing and `:workspace_roots` scoped/glob
  compilation.
  - `codex-rs/protocol/src/permissions.rs` unit tests verify exact and
  glob materialization over multiple workspace roots.
  - `codex-rs/tui/src/status/tests.rs` and
  `codex-rs/utils/sandbox-summary/src/sandbox_summary.rs` verify the
  user-facing summaries show effective workspace roots and hide internal
  writes.
  
  I also ran `cargo check --tests` locally after the latest stack refresh
  to catch cross-crate API breakage from the private-field/accessor
  changes.

• [codex] Remove experimental instructions file config (#22724)

  ## Summary
  
  Remove the deprecated `experimental_instructions_file` config setting
  from the typed config surface and the remaining deprecation-notice
  plumbing. `model_instructions_file` remains the supported setting and
  its loading path is unchanged.
  
  The setting was deprecated when it was renamed to
  `model_instructions_file` on January 20, 2026 in
  https://github.com/openai/codex/pull/9555.
  
  ## Changes
  
  - Remove `experimental_instructions_file` from `ConfigToml` and
  `ConfigProfile`.
  - Delete the custom config-layer scan and session deprecation notice for
  the removed setting.
  - Stop clearing the removed field from generated session config locks.
  - Remove the obsolete deprecation-notice test case while keeping
  `model_instructions_file` coverage intact.
  
  ## Validation
  
  - `just write-config-schema`
  - `just fmt`
  - `cargo test -p codex-config`
  - `cargo test -p codex-core model_instructions_file`
  - `just fix -p codex-core`
  - `git diff --check`

• Remove SSE fixture loaders (#22684)

  ## Why
  
  The Responses API test support already has structured SSE event
  builders. Keeping separate JSON fixture loaders made small mock streams
  harder to read and left an on-disk fixture for a single event.
  
  ## What changed
  
  - Removed `load_sse_fixture` and `load_sse_fixture_with_id_from_str`
  from `core_test_support`.
  - Deleted the one `tests/fixtures/incomplete_sse.json` Responses API
  fixture.
  - Replaced the remaining call sites with `responses::sse(...)` and
  existing event helpers.
  
  ## Validation
  
  - `cargo test -p codex-core --test all
  stream_no_completed::retries_on_early_close`
  - `cargo test -p codex-core --test all
  history_dedupes_streamed_and_final_messages_across_turns`

• tests: isolate codex home for live cli (#22563)

  ## Why
  
  Some core integration-test paths were creating Codex state under ambient
  `~/.codex`. In environments where `HOME=/tmp`, that showed up as
  `/tmp/.codex`, which is host-level shared state and makes these tests
  environment/order sensitive.
  
  The affected paths were:
  
  - `core/tests/suite/live_cli.rs`: `run_live()` spawned the real CLI with
  a temp cwd, but without an isolated home, so the child resolved Codex
  home from ambient `HOME`.
  - core / exec-server integration test binaries using
  `configure_test_binary_dispatch(...)`: their startup ctor installs arg0
  helper aliases like `apply_patch` and `codex-linux-sandbox`. Full
  `arg0_dispatch()` also installs aliases from ambient Codex-home
  resolution, so test-binary startup could create `CODEX_HOME/tmp/arg0`;
  with `HOME=/tmp`, that became `/tmp/.codex/tmp/arg0/...`.
  
  ## What changed
  
  - `live_cli` now gives the spawned CLI a temp `HOME` and temp
  `CODEX_HOME`.
  - arg0 alias setup now has an explicit-home form,
  `prepend_path_entry_for_codex_aliases_in(...)`, so test helpers can
  place alias state under a temp directory without relying on ambient
  `CODEX_HOME`.
  - helper re-entry behavior is preserved with
  `dispatch_arg0_if_needed()`, so aliases like `apply_patch` and
  `codex-linux-sandbox` still dispatch correctly before test alias
  installation.
  - core test support keeps the temp Codex home alive for the lifetime of
  the test binary, matching the alias lifetime.
  
  ## Verification
  
  Verified on `dev2` with `HOME=/tmp` that the focused core test-binary
  startup path no longer recreates `/tmp/.codex`.
  
  Also checked the exact `live_cli` test path under `HOME=/tmp`; on `dev2`
  it still hits the existing remote-only `cargo_bin("codex-rs")`
  resolution failure before spawning the child, but `/tmp/.codex` remains
  absent after the run.

• Fix remote environment test fixtures (#22572)

  ## Why
  The Docker remote-env coverage was failing before it reached the
  behavior those tests are meant to exercise. The remote-aware test
  fixture only registered the remote environment, so tests that
  intentionally select both `local` and `remote` could not start a turn.
  After that was fixed, two tests exposed stale fixtures: the approval
  test was auto-approving under workspace-write, and the remote
  `view_image` test was writing invalid PNG bytes.
  
  ## What Changed
  - Added `EnvironmentManager::create_for_tests_with_local(...)` so tests
  can keep the provider default while also selecting `local` explicitly.
  - Updated `build_remote_aware()` to use that test-only manager when a
  remote exec-server URL is present.
  - Changed the remote apply-patch approval helper to use
  `SandboxPolicy::new_read_only_policy()` so the test actually exercises
  approval caching per environment.
  - Replaced the hardcoded remote `view_image` PNG blob with the existing
  `png_bytes(...)` helper so the test uses a valid image fixture.
  
  ## Validation
  Ran these isolated Docker remote-env tests on the devbox with
  `$remote-tests` setup:
  -
  `suite::remote_env::apply_patch_freeform_routes_to_selected_remote_environment`
  -
  `suite::remote_env::apply_patch_approvals_are_remembered_per_environment`
  -
  `suite::remote_env::apply_patch_intercepted_exec_command_routes_to_selected_remote_environment`
  -
  `suite::remote_env::exec_command_routes_to_selected_remote_environment`
  - `suite::view_image::view_image_routes_to_selected_remote_environment`
  
  All five pass.

• Support explicit MCP OAuth client IDs (#22575)

  ## Why
  Some MCP OAuth providers require a pre-registered public client ID and
  cannot rely on dynamic client registration. Codex already supports MCP
  OAuth, but it had no way to supply that client ID from config into the
  PKCE flow.
  
  ## What changed
  - add `oauth.client_id` under `[mcp_servers.<server>]` config, including
  config editing and schema generation
  - thread the configured client ID through CLI, app-server, plugin login,
  and MCP skill dependency OAuth entrypoints
  - configure RMCP authorization with the explicit client when present,
  while preserving the existing dynamic-registration path when it is
  absent
  - add focused coverage for config parsing/serialization and OAuth URL
  generation
  
  ## Verification
  - `cargo test -p codex-config -p codex-rmcp-client -p codex-mcp -p
  codex-core-plugins`
  - `cargo test -p codex-core blocking_replace_mcp_servers_round_trips
  --lib`
  - `cargo test -p codex-core
  replace_mcp_servers_streamable_http_serializes_oauth_resource --lib`
  - `cargo test -p codex-core config_schema_matches_fixture --lib`
  
  ## Notes
  Broader local package runs still hit unrelated pre-existing stack
  overflows in:
  - `codex-app-server::in_process_start_clamps_zero_channel_capacity`
  -
  `codex-core::resume_agent_from_rollout_uses_edge_data_when_descendant_metadata_source_is_stale`

• tests: avoid ambient temp sandbox roots (#22576)

  ## Why
  Some sandboxed integration tests enabled both ambient temp roots
  (`TMPDIR` and literal `/tmp`) even though they were not testing
  temp-root behavior. On Linux bwrap, making `/tmp` writable causes
  protected metadata mount targets such as `/tmp/.git`, `/tmp/.agents`,
  and `/tmp/.codex` to be synthesized. If a run is interrupted, those
  top-level markers can be left behind and contaminate later tests.
  
  ## What changed
  For the incidental integration tests that do not need ambient temp-root
  access, set `exclude_tmpdir_env_var` and `exclude_slash_tmp` to `true`.
  Dedicated protected-metadata coverage remains in the lower-level sandbox
  tests that use isolated temp roots.
  
  ## Verification
  Focused remote devbox repros passed with a watcher polling `/tmp/.git`,
  `/tmp/.agents`, and `/tmp/.codex`; no leaked markers were observed.

• feat: add layered --profile-v2 config files (#17141)

  ## Why
  
  `--profile-v2 <name>` gives launchers and runtime entry points a named
  profile config without making each profile duplicate the base user
  config. The base `$CODEX_HOME/config.toml` still loads first, then
  `$CODEX_HOME/<name>.config.toml` layers above it and becomes the active
  writable user config for that session.
  
  That keeps shared defaults, plugin/MCP setup, and managed/user
  constraints in one place while letting a named profile override only the
  pieces that need to differ.
  
  ## What Changed
  
  - Added the shared `--profile-v2 <name>` runtime option with validated
  plain names, now represented by `ProfileV2Name`.
  - Extended config layer state so the base user config and selected
  profile config are both `User` layers; APIs expose the active user layer
  and merged effective user config.
  - Threaded profile selection through runtime entry points: `codex`,
  `codex exec`, `codex review`, `codex resume`, `codex fork`, and `codex
  debug prompt-input`.
  - Made user-facing config writes go to the selected profile file when
  active, including TUI/settings persistence, app-server config writes,
  and MCP/app tool approval persistence.
  - Made plugin, marketplace, MCP, hooks, and config reload paths read
  from the merged user config so base and profile layers both participate.
  - Updated app-server config layer schemas to mark profile-backed user
  layers.
  
  ## Limits
  
  `--profile-v2` is still rejected for config-management subcommands such
  as feature, MCP, and marketplace edits. Those paths remain tied to the
  base `config.toml` until they have explicit profile-selection semantics.
  
  Some adjacent background writes may still update base or global state
  rather than the selected profile:
  
  - marketplace auto-upgrade metadata
  - automatic MCP dependency installs from skills
  - remote plugin sync or uninstall config edits
  - personality migration marker/default writes
  
  ## Verification
  
  Added targeted coverage for profile name validation, layer
  ordering/merging, selected-profile writes, app-server config writes,
  session hot reload, plugin config merging, hooks/config fixture updates,
  and MCP/app approval persistence.

• Spill oversized PreToolUse additionalContext (#22529)

  # Why
  
  `PreToolUse.additionalContext` became model-visible after #20692, but
  the hook-output spilling path from #21069 never picked up that newer
  lane. As a result, oversized `PreToolUse` context could bypass the
  truncation/spill treatment that already applies to the other hook
  outputs Codex forwards to the model.
  
  # What
  
  - Run `PreToolUseOutcome.additional_contexts` through
  `maybe_spill_texts(...)`
  - Add an integration test proving a large `PreToolUse.additionalContext`
  is replaced with a truncated preview plus spill-file pointer, while the
  full text is preserved on disk.

• [codex] Remove unused legacy shell tools (#22246)

  ## Why
  
  Recent session history showed no active use of the raw `shell`,
  `local_shell`, or `container.exec` execution surfaces. Keeping those
  handlers/specs wired into core leaves duplicate shell execution paths
  alongside the supported `shell_command` and unified exec tools.
  
  ## What changed
  
  - Removed the raw `shell` handler/spec and its `ShellToolCallParams`
  protocol helper.
  - Removed the legacy `local_shell` and `container.exec` handler/spec
  plumbing while preserving persisted-history compatibility for old
  response items.
  - Normalized model/config `default` and `local` shell selections to
  `shell_command`.
  - Pruned tests that exercised removed raw-shell/local-shell/apply-patch
  variants and kept coverage on `shell_command`, unified exec, and
  freeform `apply_patch`.
  
  ## Verification
  
  - `git diff --check`
  - `cargo test -p codex-protocol`
  - `cargo test -p codex-tools`
  - `cargo test -p codex-core tools::handlers::shell`
  - `cargo test -p codex-core tools::spec`

• fix: drop underscored id headers (#22193)

  ## Why
  Stop sending duplicate `session_id`/`thread_id` headers. We only want
  the hyphenated forms as `_` is rejected by some proxies
  
  Related discussion here:
  https://openai.slack.com/archives/C095U48JNL9/p1778508316923179
  
  ## What
  - Keep `session-id` and `thread-id`
  - Remove the underscore aliases

• Add service tier overrides to spawned agents (#22139)

  ## Why
  
  Spawned agents can already override `model` and `reasoning_effort`, but
  they have no equivalent way to opt into a model-supported service tier.
  That makes it impossible to preserve or intentionally select tiered
  execution behavior when delegating work to a sub-agent, even though the
  model catalog already advertises supported `service_tiers`.
  
  ## What changed
  
  - Add optional `service_tier` to both legacy and `MultiAgentV2`
  `spawn_agent` tool inputs.
  - Show each picker-visible model's supported service tier ids and
  descriptions in the `spawn_agent` tool guidance.
  - Resolve service tier selection after the child agent's effective model
  is known.
  - Inherit the parent tier when omitted and still supported by the final
  child model; otherwise clear it.
  - Reject explicit unsupported tier requests with a model-facing error.
  - Keep explicit `service_tier` usable on full-history forks, while still
  honoring the existing model/reasoning fork restrictions.
  - Hide `service_tier` alongside other spawn metadata when
  `hide_spawn_agent_metadata` is enabled.
  
  ## Verification
  
  Added focused coverage for:
  
  - v1/v2 `spawn_agent` schema exposure for `service_tier`
  - tier descriptions in spawn guidance
  - hidden-metadata suppression
  - explicit supported tier selection
  - explicit unknown and unsupported tier rejection
  - inherited tier preservation or clearing based on child-model support
  - full-history fork acceptance for explicit service tiers in both v1 and
  v2
  
  Local Rust tests were not run in this workspace per repo guidance; the
  new coverage is included for CI.

• Remove unavailable MCP placeholder tool backfill (#22439)

  ## Why
  
  `UnavailableDummyTools` kept synthetic placeholder tools alive for
  historical tool calls whose backing MCP tool was no longer available.
  That path adds stale model-visible tool specs and special routing at the
  point where unavailable MCP calls should use ordinary current-tool
  handling. This removes the runtime backfill instead of preserving a
  second compatibility lane.
  
  ## Is it safe to remove?
  
  The unavailable tools were added in #17853 after a CS issue when a
  previously-called MCP tool failed to load and was omitted from the CS
  spec. Now that we have tool search, I think this is resolved:
  - API merges tools from previous TST output into effective tool set so
  theyre always in CS spec
  - if an MCP tool surfaced by TST later becomes unavailable, the model
  can still call it and it will just return model-visible error
  - both TST output and function call output are dropped on compaction so
  model will not remember old calls to MCP post compaction
  
  ## What changed
  
  - Delete unavailable-tool collection, placeholder handler, router/spec
  plumbing, and obsolete placeholder coverage.
  - Keep `features.unavailable_dummy_tools` as a removed no-op feature
  tombstone so existing configs still parse cleanly.
  - Add an integration-style `tool_search` regression test showing that a
  deferred MCP tool surfaced through `tool_search` still routes through
  MCP and returns a model-visible tool-call error rather than `unsupported
  call`.
  
  ## Verification
  
  - `cargo test -p codex-core tool_search`

• Remove CODEX_RS_SSE_FIXTURE test hook (#22413)

  ## Why
  
  `CODEX_RS_SSE_FIXTURE` let integration-style CLI, exec, and TUI tests
  bypass the normal Responses transport by reading SSE from local files.
  That kept test-only behavior wired through production client code. The
  affected tests can stay hermetic by using the existing
  `core_test_support::responses` mock server and passing `openai_base_url`
  instead.
  
  ## What Changed
  
  - Removed the `CODEX_RS_SSE_FIXTURE` flag,
  `codex_api::stream_from_fixture`, the `env-flags` dependency, and the
  checked-in SSE fixture files.
  - Repointed the affected core, exec, and TUI tests at `MockServer` with
  the existing SSE event constructors.
  - Removed the Bazel test data plumbing for the deleted fixtures and
  refreshed cargo/Bazel lock state.
  
  ## Verification
  
  - `cargo build -p codex-cli`
  - `cargo test -p codex-api`
  - `cargo test -p codex-core --test all responses_api_stream_cli`
  - `cargo test -p codex-core --test all

• Unify thread metadata updates above store (#22236)

  - make ThreadStore::update_thread_metadata accept a broad range of
  metadata patches
  - keep ThreadStore::append_items as raw canonical history append (no
  metadata side effects)
  - in the local store, write these metadata updates to a combination of
  sqlite and rollout jsonl files for backwards-compat. It special cases
  which fields need to go into jsonl vs sqlite vs whatever, confining the
  awkwardness to just this implementation
  - in remote stores we can simply persist the metadata directly to a
  database, no special casing required.
  - move the "implicit metadata updates triggered by appending rollout
  items" from the RolloutRecorder (which is local-threadstore-specific) to
  the LiveThread layer above the ThreadStore, inside of a private helper
  utility called ThreadMetadataSync. LiveThread calls ThreadStore
  append_items and update_metadata separately.
  - Add a generic update metadata method to ThreadManager that works on
  both live threads and "cold" threads
  - Call that ThreadManager method from app server code, so app server
  doesn't need to worry about whether the thread is live or not

• [codex] Add search term coverage for tool_search (#22398)

  ## Why
  
  `tool_search` already had solid end-to-end coverage for discovery and
  follow-up execution, but it did not prove that distinct pieces of
  indexed search text actually work in integration. In particular, we were
  not exercising whether unique tool names, descriptions, namespaces,
  underscore-expanded dynamic names, and schema-property terms were
  sufficient to surface the expected deferred tools.
  
  This change adds focused integration coverage for those term sources so
  regressions in search text construction are caught by a real `TestCodex`
  flow instead of only by lower-level unit tests.
  
  ## What changed
  
  - added a small helper in `core/tests/suite/search_tool.rs` to assert
  that a `tool_search_output` contains an expected namespace child tool
  - added an MCP integration test that issues several `tool_search_call`s
  and verifies distinct query terms match the expected app tools:
    - exact tool name: `calendar_timezone_option_99`
    - tool description phrase: `uploaded document`
    - top-level schema property: `starts_at`
  - added a dynamic-tool integration test that verifies distinct query
  terms match the expected deferred dynamic tool:
    - exact name: `quasar_ping_beacon`
    - underscore-expanded name: `quasar ping beacon`
    - description phrase: `saffron metronome`
    - namespace: `orbit_ops`
    - schema property: `chrono_spec`
  
  ## Validation
  
  - `cargo test -p codex-core tool_search_matches_`
  
  ## Docs
  
  No documentation update needed.

• Refactor namespaced tool spec registration (#22256)

  ## Summary
  
  This refactor makes tool handlers the owner of the specs they can
  publish, so registry construction can register handlers once and
  separately publish only the specs that should be model-visible.
  
  The main motivation is deferred tools: MCP and dynamic tools still need
  handlers registered up front, but deferred tools should be discoverable
  through `tool_search` rather than emitted in the initial tool spec list.
  
  ## What changed
  
  - `McpHandler` and `DynamicToolHandler` can return their own `ToolSpec`.
  - `build_tool_registry_builder` now collects handlers, registers them
  through the no-spec path, and publishes only non-deferred handler specs.
  - Deferred MCP and dynamic tool names are combined into one
  `all_deferred_tools` set that drives spec filtering, code-mode
  deferred-tool signaling, and `tool_search` registration.
  - `tool_search` registration now requires both deferred tools and
  `namespace_tools`.
  - Namespace specs are merged in `spec_plan`, preserving top-level spec
  order, sorting tools within each namespace, and backfilling empty
  namespace descriptions.
  - Hosted web search and image-generation specs are included in the
  collected spec vector before namespace merge/publication, and tool-name
  tests that should not care about hosted relative order now compare sets.
  
  ## Testing
  
  - `cargo test -p codex-core tools::spec::tests:: -- --nocapture`
  - `cargo test -p codex-core tools::spec_plan::tests:: -- --nocapture`
  - `cargo test -p codex-core

  - `cargo test -p codex-core -- --skip
  tools::handlers::multi_agents::tests::tool_handlers_cascade_close_and_resume_and_keep_explicitly_closed_subtrees_closed`
  passed the library suite after skipping the known stack-overflowing unit
  test.
  
  Full `cargo test -p codex-core` currently hits a stack overflow in
  `tools::handlers::multi_agents::tests::tool_handlers_cascade_close_and_resume_and_keep_explicitly_closed_subtrees_closed`;
  the same focused test reproduces on `origin/main`.

• feat(sandbox): add Windows deny-read parity (#18202)

  ## Why
  
  The split filesystem policy stack already supports exact and glob
  `access = none` read restrictions on macOS and Linux. Windows still
  needed subprocess handling for those deny-read policies without claiming
  enforcement from a backend that cannot provide it.
  
  ## Key finding
  
  The unelevated restricted-token backend cannot safely enforce deny-read
  overlays. Its `WRITE_RESTRICTED` token model is authoritative for write
  checks, not read denials, so this PR intentionally fails that backend
  closed when deny-read overrides are present instead of claiming
  unsupported enforcement.
  
  ## What changed
  
  This PR adds the Windows deny-read enforcement layer and makes the
  backend split explicit:
  
  - Resolves Windows deny-read filesystem policy entries into concrete ACL
  targets.
  - Preserves exact missing paths so they can be materialized and denied
  before an enforceable sandboxed process starts.
  - Snapshot-expands existing glob matches into ACL targets for Windows
  subprocess enforcement.
  - Honors `glob_scan_max_depth` when expanding Windows deny-read globs.
  - Plans both the configured lexical path and the canonical target for
  existing paths so reparse-point aliases are covered.
  - Threads deny-read overrides through the elevated/logon-user Windows
  sandbox backend and unified exec.
  - Applies elevated deny-read ACLs synchronously before command launch
  rather than delegating them to the background read-grant helper.
  - Reconciles persistent deny-read ACEs per sandbox principal so policy
  changes do not leave stale deny-read ACLs behind.
  - Fails closed on the unelevated restricted-token backend when deny-read
  overrides are present, because its `WRITE_RESTRICTED` token model is not
  authoritative for read denials.
  
  ## Landed prerequisites
  
  These prerequisite PRs are already on `main`:
  
  1. #15979 `feat(permissions): add glob deny-read policy support`
  2. #18096 `feat(sandbox): add glob deny-read platform enforcement`
  3. #17740 `feat(config): support managed deny-read requirements`
  
  This PR targets `main` directly and contains only the Windows deny-read
  enforcement layer.
  
  ## Implementation notes
  
  - Exact deny-read paths remain enforceable on the elevated path even
  when they do not exist yet: Windows materializes the missing path before
  applying the deny ACE, so the sandboxed command cannot create and read
  it during the same run.
  - Existing exact deny paths are preserved lexically until the ACL
  planner, which then adds the canonical target as a second ACL target
  when needed. That keeps both the configured alias and the resolved
  object covered.
  - Windows ACLs do not consume Codex glob syntax directly, so glob
  deny-read entries are expanded to the concrete matches that exist before
  process launch.
  - Glob traversal deduplicates directory visits within each pattern walk
  to avoid cycles, without collapsing distinct lexical roots that happen
  to resolve to the same target.
  - Persistent deny-read ACL state is keyed by sandbox principal SID, so
  cleanup only removes ACEs owned by the same backend principal.
  - Deny-read ACEs are fail-closed on the elevated path: setup aborts if
  mandatory deny-read ACL application fails.
  - Unelevated restricted-token sessions reject deny-read overrides early
  instead of running with a silently unenforceable read policy.
  
  ## Verification
  
  - `cargo test -p codex-core
  windows_restricted_token_rejects_unreadable_split_carveouts`
  - `just fmt`
  - `just fix -p codex-core`
  - `just fix -p codex-windows-sandbox`
  - GitHub Actions rerun is in progress on the pushed head.

• [codex] Filter legacy warning messages during compaction (#22243)

  ## Why
  
  Older sessions can contain model-warning records persisted as `user`
  messages, including the unified exec process-limit warning, the
  `apply_patch`-via-`exec_command` warning, and the model-mismatch
  high-risk cyber fallback warning. Those warnings are no longer produced
  as conversation history items, but when old sessions compact they should
  still be recognized as injected context rather than preserved as real
  user turns.
  
  ## What changed
  
  - Removed `record_model_warning` and the production paths that emitted
  these warning messages into conversation history.
  - Added `LegacyUnifiedExecProcessLimitWarning`,
  `LegacyApplyPatchExecCommandWarning`, and `LegacyModelMismatchWarning`
  contextual fragments that are used only for matching old persisted
  messages.
  - Registered the legacy fragments with contextual user message detection
  so compaction filters them through the existing fragment path.
  - Added focused compaction coverage for old warning messages being
  dropped during compacted-history processing.
  
  ## Testing
  
  - `cargo test -p codex-core warning`
  - `just fix -p codex-core`

• Support PreToolUse updatedInput rewrites (#20527)

  ## Why
  
  `PreToolUse` already exposes `updatedInput` in its hook output schema,
  but Codex currently rejects it instead of applying the rewrite. That
  leaves hook authors unable to make the documented pre-execution
  adjustment to a tool call before it runs.
  
  ## What
  
  - Accept `updatedInput` from `PreToolUse` hooks when paired with
  `permissionDecision: "allow"`.
  - Apply the rewritten input before dispatch so the tool executes the
  updated payload, not the original one.
  - Preserve the stable hook-facing compatibility shapes that
  participating tool handlers expose:
  - Bash-like tools (`shell`, `container.exec`, `local_shell`,
  `shell_command`, `exec_command`) use `{ "command": ... }`.
  - `apply_patch` exposes its patch body through the same command-shaped
  hook contract.
    - MCP tools expose their JSON argument object directly.
  - Keep each participating tool handler responsible for translating
  hook-facing `updatedInput` back into its concrete invocation shape.
  
  ## Verification
  
  Direct Bash-like rewrite coverage:
  
  - `pre_tool_use_rewrites_shell_before_execution`
  - `pre_tool_use_rewrites_container_exec_before_execution`
  - `pre_tool_use_rewrites_local_shell_before_execution`
  - `pre_tool_use_rewrites_shell_command_before_execution`
  - `pre_tool_use_rewrites_exec_command_before_execution`
  
  These cases assert that each supported Bash-like surface runs only the
  rewritten command while the hook still observes the original `{
  "command": ... }` input.
  
  `pre_tool_use_rewrites_apply_patch_before_execution`
  
  - Model emits one patch.
  - Hook swaps in a different patch.
  - Asserts only the rewritten file is created, and the hook saw the
  original patch.
  
  `pre_tool_use_rewrites_code_mode_nested_exec_command_before_execution`
  
  - Model runs one nested shell command from code mode.
  - Hook rewrites it.
  - Asserts only the rewritten command runs, and the hook saw the original
  nested input.
  
  `pre_tool_use_rewrites_mcp_tool_before_execution`
  
  - Model calls the RMCP echo tool.
  - Hook rewrites the MCP arguments.
  - Asserts the MCP server receives and returns the rewritten message, not
  the original one.

• feat: add network proxy feature flag (#20147)

  ## Why
  
  The permissions migration is making
  `permissions.<profile>.network.enabled` the canonical sandbox network
  bit, while proxy startup is a separate concern. Enabling network access
  should not implicitly start the proxy, and users who are still on legacy
  sandbox modes need a separate place to opt into proxy startup and
  provide proxy-specific settings.
  
  This follow-up to #19900 gives the network proxy its own feature surface
  instead of overloading permission-profile network semantics.
  
  ## What changed
  
  - Add an experimental `network_proxy` feature with a configurable
  `[features.network_proxy]` table.
  - Overlay `features.network_proxy` settings onto the configured proxy
  state after permission-profile selection, so the proxy only starts when
  the active `NetworkSandboxPolicy` already allows network access.
  - Preserve `[experimental_network]` startup behavior independently of
  the new feature flag.
  
  ## Behavior and examples
  
  There are now three related knobs:
  
  - `permissions.<profile>.network.enabled` controls whether the active
  permission profile has network access at all.
  - `features.network_proxy` enables proxy restrictions for an
  already-network-enabled profile.
  - Legacy `sandbox_mode` plus `[sandbox_workspace_write].network_access`
  still control whether legacy `workspace-write` has network access at
  all.
  
  The rule is:
  
  - network off + proxy flag on -> network stays off, proxy is a no-op
  - network on + proxy flag off -> unrestricted direct network
  - network on + proxy flag on -> network stays on, with proxy
  restrictions applied
  
  For permission profiles, the feature toggle adds proxy restrictions only
  when network access is already enabled:
  
  ```toml
  default_permissions = "workspace"
  
  [permissions.workspace.filesystem]
  ":minimal" = "read"
  
  [permissions.workspace.network]
  enabled = true
  
  [features]
  network_proxy = true
  ```
  
  If `network.enabled = false`, the same feature flag is a no-op: network
  remains off and the proxy does not start.
  
  For legacy sandbox config, `network_access` remains the master switch:
  
  ```toml
  sandbox_mode = "workspace-write"
  
  [sandbox_workspace_write]
  network_access = true
  
  [features]
  network_proxy = true
  ```
  
  That keeps legacy `workspace-write` network access on, but routes it
  through the proxy policy. If `network_access = false`, the proxy feature
  is a no-op and legacy `workspace-write` remains offline.
  
  The same proxy opt-in can be supplied from the CLI:
  
  ```bash
  codex -c 'features.network_proxy=true'
  ```
  
  Additional proxy settings can be supplied when a table is needed:
  
  ```bash
  codex \
    -c 'features.network_proxy.enabled=true' \
    -c 'features.network_proxy.enable_socks5=false'
  ```
  
  The intended behavior matrix is:
  
  | Config surface | Network setting | `features.network_proxy` | Direct
  sandbox network | Proxy |
  | --- | --- | --- | --- | --- |
  | Permission profile | `network.enabled = false` | off | restricted |
  off |
  | Permission profile | `network.enabled = false` | on | restricted | off
  |
  | Permission profile | `network.enabled = true` | off | enabled | off |
  | Permission profile | `network.enabled = true` | on | enabled | on |
  | Legacy `workspace-write` | `network_access = false` | off | restricted
  | off |
  | Legacy `workspace-write` | `network_access = false` | on | restricted
  | off |
  | Legacy `workspace-write` | `network_access = true` | off | enabled |
  off |
  | Legacy `workspace-write` | `network_access = true` | on | enabled | on
  |
  
  `[experimental_network]` requirements remain separate from the user
  feature toggle and still start the proxy on their own.
  
  Relevant code:
  -
  [`features/src/feature_configs.rs`](https://github.com/openai/codex/blob/43785aff47/codex-rs/features/src/feature_configs.rs#L58-L117)
  defines the feature-specific proxy config.

  [`core/src/config/mod.rs`](https://github.com/openai/codex/blob/43785aff47/codex-rs/core/src/config/mod.rs#L1959-L1964)
  reads the feature table, and [later applies it only when network access
  is already
  enabled](https://github.com/openai/codex/blob/43785aff47/codex-rs/core/src/config/mod.rs#L2448-L2458).
  
  ## Verification
  
  Added focused coverage for:
  - keeping the proxy off when `features.network_proxy` is enabled but
  sandbox network access is disabled
  - the full permission-profile and legacy `workspace-write` matrix above
  - preserving `[experimental_network]` startup without the feature
  - reusing profile-supplied proxy settings when the feature is enabled
  
  Ran:
  - `cargo test -p codex-features`
  - `cargo test -p codex-core network_proxy_feature`
  - `cargo test -p codex-core
  experimental_network_requirements_enable_proxy_without_feature`

• fix(exec-policy) use is_known_safe_command less (#20305)

  ## Summary
  Restricts behavior of `is_known_safe_command` only to modes where it is
  explicitly part of the documented behavior:
  - when `environment_lacks_sandbox_protections`
  - in `AskForApproval::UnlessTrusted`
  
  Notably, as a result of this, escalations for commands that pass
  `is_known_safe_commands` are no longer auto-approved in
  AskForApproval::OnRequest or AskForApproval::Granular.
  
  ## Testing
  - [x] Updated unit tests
  - [x] Updated approvals scenario tests.
