• feat: split memories part 2 (#19860)

  Keep extracting memories out of core and moving the write trigger in the
  app-server
  This is temporary and it should move at the client level as a follow-up
  This makes core fully independant from `codex-memories-write`

• permissions: derive snapshot sandbox projections (#19775)

  ## Why
  
  `ThreadConfigSnapshot` is used by app-server and thread metadata code as
  a stable view of active runtime settings. Keeping both `sandbox_policy`
  and `permission_profile` in the snapshot duplicates permission state and
  makes it possible for the legacy projection to drift from the canonical
  profile.
  
  The legacy `sandbox` value is still needed at app-server compatibility
  boundaries, so this PR derives it on demand from the snapshot profile
  and cwd instead of storing it.
  
  ## What Changed
  
  - Removes `ThreadConfigSnapshot.sandbox_policy`.
  - Adds `ThreadConfigSnapshot::sandbox_policy()` as a compatibility
  projection from `permission_profile` plus `cwd`.
  - Updates app-server response/metadata code and tests to call the
  projection only where legacy fields still exist.
  - Keeps snapshot construction profile-only so split filesystem rules,
  disabled enforcement, and external enforcement remain represented by the
  canonical profile.
  
  ## Verification
  
  - `cargo test -p codex-app-server
  thread_response_permission_profile_preserves_enforcement --lib`
  - `cargo test -p codex-core
  dispatch_reclaims_stale_global_lock_and_starts_consolidation --lib`

• permissions: make SessionConfigured profile-only (#19774)

  ## Why
  
  `SessionConfiguredEvent` is the internal event that tells clients what
  permissions are active for a session. Emitting both `sandbox_policy` and
  `permission_profile` leaves two possible authorities and forces every
  consumer to decide which one to honor. At this point in the migration,
  the profile is expressive enough to represent managed, disabled, and
  external sandbox enforcement, so the internal event can be profile-only.
  
  The wire compatibility concern is older serialized events or rollout
  data that only contain `sandbox_policy`; those still need to
  deserialize.
  
  ## What Changed
  
  - Removes `sandbox_policy` from `SessionConfiguredEvent` and makes
  `permission_profile` required.
  - Adds custom deserialization so old payloads with only `sandbox_policy`
  are upgraded to a cwd-anchored `PermissionProfile`.
  - Updates core event emission and TUI session handling to sync
  permissions from the profile directly.
  - Updates app-server response construction to derive the legacy
  `sandbox` response field from the active thread snapshot instead of from
  `SessionConfiguredEvent`.
  - Updates yolo-mode display logic to treat both
  `PermissionProfile::Disabled` and managed unrestricted filesystem plus
  enabled network as full-access, while still preserving the distinction
  between no sandbox and external sandboxing.
  
  ## Verification
  
  - `cargo test -p codex-protocol session_configured_event --lib`
  - `cargo test -p codex-protocol serialize_event --lib`
  - `cargo test -p codex-exec session_configured --lib`
  - `cargo test -p codex-app-server

• Streamline review and feedback handlers (#19498)

  ## Why
  
  The remaining review, interrupt, fuzzy search, feedback, and git-diff
  handlers still had local send-error branches that obscured otherwise
  simple request handling. This final slice flattens those handlers
  without changing the public protocol behavior.
  
  ## What Changed
  
  - Streamlined review start, turn interrupt, fuzzy search session,
  feedback upload, and git diff handlers in
  `codex-rs/app-server/src/codex_message_processor.rs`.
  - Converted validation and upload failures into returned JSON-RPC errors
  where that avoids nested `send_error`/`return` blocks.
  - Left unrelated sandbox setup and notification code untouched.
  
  ## Verification
  
  - `cargo check -p codex-app-server`
  - `cargo test -p codex-app-server --test all v2::review --
  --test-threads=1`

• Streamline turn and realtime handlers (#19497)

  ## Why
  
  Turn and realtime handlers had nested validation and send-error branches
  that made the request path longer than the behavior warranted. This
  slice keeps the same request semantics while letting the handlers return
  errors from the failing step.
  
  ## What Changed
  
  - Streamlined turn start, injected item, and turn steer request handling
  in `codex-rs/app-server/src/codex_message_processor.rs`.
  - Applied the same result-returning shape to realtime session response
  handlers.
  - Preserved existing request validation and thread-manager interactions.
  
  ## Verification
  
  - `cargo check -p codex-app-server`
  - `cargo test -p codex-app-server --test all v2::turn_start --
  --test-threads=1`
  - `cargo test -p codex-app-server --test all v2::turn_steer --

• Streamline thread resume and fork handlers (#19495)

  ## Why
  
  Thread resume and fork had some of the deepest error-handling
  indentation in this area because helpers emitted request errors
  directly. Returning those failures gives the handlers a single request
  boundary while preserving the async pending-resume behavior.
  
  ## What Changed
  
  - Converted thread resume helpers in
  `codex-rs/app-server/src/codex_message_processor.rs` to return `Result`
  values for validation and view loading failures.
  - Applied the same pattern to thread fork request handling.
  - Simplified pending resume error construction by using the shared
  JSON-RPC error helpers.
  
  ## Verification
  
  - `cargo check -p codex-app-server`
  - `cargo test -p codex-app-server --test all v2::thread_resume --
  --test-threads=1`
  - `cargo test -p codex-app-server --test all v2::thread_fork --

• Streamline thread read handlers (#19494)

  ## Why
  
  The thread read/list handlers mostly assemble views, but their error
  handling was interleaved with response emission. Returning view-building
  errors from the helper path keeps those handlers focused on data
  assembly.
  
  ## What Changed
  
  - Added a small mapper for `ThreadReadViewError` to JSON-RPC errors in
  `codex-rs/app-server/src/codex_message_processor.rs`.
  - Streamlined thread list, loaded-thread, read, turn-list, and summary
  handlers to produce result values for the request boundary.
  - Kept the existing invalid-request vs internal-error distinctions for
  missing or unreadable thread data.
  
  ## Verification
  
  - `cargo check -p codex-app-server`
  - `cargo test -p codex-app-server --test all conversation_summary --
  --test-threads=1`

• Streamline thread mutation handlers (#19493)

  ## Why
  
  Thread mutation handlers had many short error branches whose only job
  was to emit a JSON-RPC error and stop. This slice keeps those errors
  visible, but lets each handler build a result and return early from
  validation helpers instead of nesting the main path.
  
  ## What Changed
  
  - Streamlined thread archive/unarchive, rename, memory, metadata,
  rollback, compact, background terminal, shell, and guardian handlers in
  `codex-rs/app-server/src/codex_message_processor.rs`.
  - Reused shared JSON-RPC error constructors in
  `codex-rs/app-server/src/bespoke_event_handling.rs` for rollback-related
  request failures.
  - Preserved direct `send_error` calls where they remain the simplest
  boundary for pending async event responses.
  
  ## Verification
  
  - `cargo check -p codex-app-server`
  - `cargo test -p codex-app-server --test all v2::thread_rollback --
  --test-threads=1`

• Streamline thread start handler (#19492)

  ## Why
  
  The thread start handler mixed request validation, thread construction,
  dynamic-tool validation, and JSON-RPC error emission in one nested flow.
  Returning request errors from the helper path makes the successful setup
  path easier to follow.
  
  ## What Changed
  
  - Reworked `thread/start` handling in
  `codex-rs/app-server/src/codex_message_processor.rs` so helper methods
  return `Result` and the handler emits one result.
  - Moved dynamic-tool validation failures into returned JSON-RPC errors
  instead of local `send_error` branches.
  - Preserved the existing thread creation and task-spawning behavior.
  
  ## Verification
  
  - `cargo check -p codex-app-server`
  - `cargo test -p codex-app-server --test all v2::dynamic_tools --
  --test-threads=1`
  - `cargo test -p codex-app-server --test all v2::turn_start --

• Streamline account and command handlers (#19491)

  ## Why
  
  Account login/logout and command exec handlers were doing local error
  sends in the middle of each handler. That made these request flows
  branch heavily even though most of the logic is validate, perform the
  operation, and return the response.
  
  ## What Changed
  
  - Converted ChatGPT/API-key login, login cancel, logout, rate-limit, and
  add-credit handlers in
  `codex-rs/app-server/src/codex_message_processor.rs` to compute `Result`
  values and send them once at the request boundary.
  - Applied the same shape to command exec start/write/resize/terminate
  handlers.
  - Kept side-effect notifications in the same places after successful
  request handling.
  
  ## Verification
  
  - `cargo check -p codex-app-server`
  - `cargo test -p codex-app-server --test all v2::account --
  --test-threads=1`
  - `cargo test -p codex-app-server --test all v2::command_exec --

• refactor: make auth loading async (#19762)

  ## Summary
  
  Auth loading used to expose synchronous construction helpers in several
  places even though some auth sources now need async work. This PR makes
  the auth-loading surface async and updates the callers to await it.
  
  This is intentionally only plumbing. It does not change how
  AgentIdentity tokens are decoded, how task runtime ids are allocated, or
  how JWT signatures are verified.
  
  ## Stack
  
  1. **This PR:** [refactor: make auth loading
  async](https://github.com/openai/codex/pull/19762)
  2. [refactor: load AgentIdentity runtime
  eagerly](https://github.com/openai/codex/pull/19763)
  3. [feat: verify AgentIdentity JWTs with
  JWKS](https://github.com/openai/codex/pull/19764)
  
  ## Important call sites
  
  | Area | Change |
  | --- | --- |
  | `codex-login` auth loading | `CodexAuth` and `AuthManager`
  construction paths now await auth loading. |
  | app-server startup | Auth manager construction is awaited during
  initialization. |
  | CLI/TUI/exec/MCP/chatgpt callers | Existing auth-loading calls now
  await the same behavior. |
  | cloud requirements storage loader | The loader becomes async so it can
  share the same auth construction path. |
  | auth tests | Tests that load auth now run in async contexts. |
  
  ## Testing
  
  Tests: targeted Rust auth test compilation, formatter, scoped Clippy
  fix, and Bazel lock check.

• Streamline plugin, apps, and skills handlers (#19490)

  ## Why
  
  The plugin, app, and skills handlers had a lot of repeated
  `send_error`/`return` branches that made the success path hard to scan.
  This slice keeps behavior the same while moving fallible steps into
  local response-producing helpers, so the request boundary can send one
  result.
  
  ## What Changed
  
  - Converted plugin list/install/uninstall handlers in
  `codex-rs/app-server/src/codex_message_processor/plugins.rs` to return
  `Result<*Response, JSONRPCErrorError>` from helper methods and call
  `send_result` once.
  - Added local error-mapping helpers for plugin install/uninstall and
  marketplace failures.
  - Applied the same mechanical shape to app list, skills list/config, and
  marketplace add/remove/upgrade handlers in
  `codex-rs/app-server/src/codex_message_processor.rs`.
  
  ## Verification
  
  - `cargo check -p codex-app-server`
  - `cargo test -p codex-app-server --test all v2::app_list --
  --test-threads=1`
  - `cargo test -p codex-app-server --test all v2::plugin_ --

• permissions: centralize legacy sandbox projection (#19734)

  ## Why
  
  The remaining migration work still needs `SandboxPolicy` at a few
  compatibility boundaries, but those projections should come from one
  canonical path. Keeping ad hoc legacy projections scattered through
  app-server, CLI, and config code makes it easy for behavior to drift as
  `PermissionProfile` gains fidelity that the legacy enum cannot
  represent.
  
  ## What Changed
  
  - Adds `Permissions::legacy_sandbox_policy(cwd)` and
  `Config::legacy_sandbox_policy()` as the compatibility projection from
  the canonical `PermissionProfile`.
  - Adds `Permissions::can_set_legacy_sandbox_policy()` so legacy inputs
  are checked after they are converted into profile semantics.
  - Updates app-server command handling, Windows sandbox setup, session
  configuration, and sandbox summaries to use the centralized projection
  helper.
  - Leaves `SandboxPolicy` in place only for boundary inputs/outputs that
  still speak the legacy abstraction.
  
  ## Verification
  
  - `cargo check -p codex-config -p codex-core -p codex-sandboxing -p
  codex-app-server -p codex-cli -p codex-tui`
  - `cargo test -p codex-tui
  permissions_selection_history_snapshot_full_access_to_default --

  - `cargo test -p codex-tui

  - `bazel test //codex-rs/tui:tui-unit-tests-bin
  --test_arg=permissions_selection_history_snapshot_full_access_to_default

  - `bazel test //codex-rs/tui:tui-unit-tests-bin

• permissions: migrate approval and sandbox consumers to profiles (#19393)

  ## Why
  
  Runtime decisions should not infer permissions from the lossy legacy
  sandbox projection once `PermissionProfile` is available. In particular,
  `Disabled` and `External` need to remain distinct, and managed profiles
  with split filesystem or deny-read rules should not be collapsed before
  approval, network, safety, or analytics code makes decisions.
  
  ## What Changed
  
  - Changes managed network proxy setup and network approval logic to use
  `PermissionProfile` when deciding whether a managed sandbox is active.
  - Migrates patch safety, Guardian/user-shell approval paths, Landlock
  helper setup, analytics sandbox classification, and selected
  turn/session code to profile-backed permissions.
  - Validates command-level profile overrides against the constrained
  `PermissionProfile` rather than a strict `SandboxPolicy` round trip.
  - Preserves configured deny-read restrictions when command profiles are
  narrowed.
  - Adds coverage for profile-backed trust, network proxy/approval
  behavior, patch safety, analytics classification, and command-profile
  narrowing.
  
  ## Verification
  
  - `cargo test -p codex-core direct_write_roots`
  - `cargo test -p codex-core runtime_roots_to_legacy_projection`
  - `cargo test -p codex-app-server

• [codex] Move config loading into codex-config (#19487)

  ## Why
  
  Config loading had become split across crates: `codex-config` owned the
  config types and merge logic, while `codex-core` still owned the loader
  that assembled the layer stack. This change consolidates that
  responsibility in `codex-config`, so the crate that defines config
  behavior also owns how configs are discovered and loaded.
  
  To make that move possible without reintroducing the old dependency
  cycle, the shell-environment policy types and helpers that
  `codex-exec-server` needs now live in `codex-protocol` instead of
  flowing through `codex-config`.
  
  This also makes the migrated loader tests more deterministic on machines
  that already have managed or system Codex config installed by letting
  tests override the system config and requirements paths instead of
  reading the host's `/etc/codex`.
  
  ## What Changed
  
  - moved the config loader implementation from `codex-core` into
  `codex-config::loader` and deleted the old `core::config_loader` module
  instead of leaving a compatibility shim
  - moved shell-environment policy types and helpers into
  `codex-protocol`, then updated `codex-exec-server` and other downstream
  crates to import them from their new home
  - updated downstream callers to use loader/config APIs from
  `codex-config`
  - added test-only loader overrides for system config and requirements
  paths so loader-focused tests do not depend on host-managed config state
  - cleaned up now-unused dependency entries and platform-specific cfgs
  that were surfaced by post-push CI
  
  ## Testing
  
  - `cargo test -p codex-config`
  - `cargo test -p codex-core config_loader_tests::`
  - `cargo test -p codex-protocol -p codex-exec-server -p
  codex-cloud-requirements -p codex-rmcp-client --lib`
  - `cargo test --lib -p codex-app-server-client -p codex-exec`
  - `cargo test --no-run --lib -p codex-app-server`
  - `cargo test -p codex-linux-sandbox --lib`
  - `cargo shear`
  - `just bazel-lock-check`
  
  ## Notes
  
  - I did not chase unrelated full-suite failures outside the migrated
  loader surface.
  - `cargo test -p codex-core --lib` still hits unrelated proxy-sensitive
  failures on this machine, and Windows CI still shows unrelated
  long-running/timeouting test noise outside the loader migration itself.

• permissions: derive compatibility policies from profiles (#19392)

  ## Why
  
  After #19391, `PermissionProfile` and the split filesystem/network
  policies could still be stored in parallel. That creates drift risk: a
  profile can preserve deny globs, external enforcement, or split
  filesystem entries while a cached projection silently loses those
  details. This PR makes the profile the runtime source and derives
  compatibility views from it.
  
  ## What Changed
  
  - Removes stored filesystem/network sandbox projections from
  `Permissions` and `SessionConfiguration`; their accessors now derive
  from the canonical `PermissionProfile`.
  - Derives legacy `SandboxPolicy` snapshots from profiles only where an
  older API still needs that field.
  - Updates MCP connection and elicitation state to track
  `PermissionProfile` instead of `SandboxPolicy` for auto-approval
  decisions.
  - Adds semantic filesystem-policy comparison so cwd changes can preserve
  richer profiles while still recognizing equivalent legacy projections
  independent of entry ordering.
  - Updates config/session tests to assert profile-derived projections
  instead of parallel stored fields.
  
  ## Verification
  
  - `cargo test -p codex-core direct_write_roots`
  - `cargo test -p codex-core runtime_roots_to_legacy_projection`
  - `cargo test -p codex-app-server

• permissions: make runtime config profile-backed (#19606)

  ## Why
  
  This supersedes #19391. During stack repair, GitHub marked #19391 as
  merged into a temporary stack branch rather than into `main`, so the
  runtime-config change needed a fresh PR.
  
  `PermissionProfile` is now the canonical permissions shape after #19231
  because it can distinguish `Managed`, `Disabled`, and `External`
  enforcement while also carrying filesystem rules that legacy
  `SandboxPolicy` cannot represent cleanly. Core config and session state
  still needed to accept profile-backed permissions without forcing every
  profile through the strict legacy bridge, which rejected valid runtime
  profiles such as direct write roots.
  
  The unrelated CI/test hardening that previously rode along with this PR
  has been split into #19683 so this PR stays focused on the permissions
  model migration.
  
  ## What Changed
  
  - Adds `Permissions.permission_profile` and
  `SessionConfiguration.permission_profile` as constrained runtime state,
  while keeping `sandbox_policy` as a legacy compatibility projection.
  - Introduces profile setters that keep `PermissionProfile`, split
  filesystem/network policies, and legacy `SandboxPolicy` projections
  synchronized.
  - Uses a compatibility projection for requirement checks and legacy
  consumers instead of rejecting profiles that cannot round-trip through
  `SandboxPolicy` exactly.
  - Updates config loading, config overrides, session updates, turn
  context plumbing, prompt permission text, sandbox tags, and exec request
  construction to carry profile-backed runtime permissions.
  - Preserves configured deny-read entries and `glob_scan_max_depth` when
  command/session profiles are narrowed.

• Restore persisted model provider on thread resume (#19287)

  Fixes #15219.
  
  ## Why
  
  `thread/resume` should continue a persisted thread with the same model
  provider that created the thread. The app server already restores the
  persisted model and reasoning effort before resuming, but it was leaving
  `model_provider` unset. If a user created a thread with one provider and
  later switched their active profile to another provider, resumed
  encrypted history could be sent to the wrong endpoint and fail with
  `invalid_encrypted_content`.
  
  The thread metadata already records the original provider, so resume
  should apply it when the caller has not explicitly requested a different
  model/provider/reasoning configuration.
  
  ## What changed
  
  This updates `merge_persisted_resume_metadata` in
  `app-server/src/codex_message_processor.rs` to copy
  `ThreadMetadata::model_provider` into `ConfigOverrides::model_provider`
  alongside the persisted model.
  
  The existing resume metadata tests now also assert that:
  
  - the persisted provider is restored for normal resume
  - explicit model, provider, or reasoning-effort overrides still prevent
  persisted resume metadata from being applied
  - a thread with no persisted model or reasoning effort still resumes
  with its persisted provider
  
  ## Verification
  
  - `cargo test -p codex-app-server` passed the app-server unit tests,
  including the updated resume metadata coverage. The broader integration
  portion of that command failed in an unrelated environment-sensitive
  skills-budget warning assertion, where this run saw 8 omitted skills
  instead of the expected 7.
  - `just fix -p codex-app-server` completed successfully.

• Add goal core runtime (4 / 5) (#18076)

  Adds the core runtime behavior for active goals on top of the model
  tools from PR 3.
  
  ## Why
  
  A long-running goal should be a core runtime concern, not something
  every client has to implement. Core owns the turn lifecycle, tool
  completion boundaries, interruptions, resume behavior, and token usage,
  so it is the right place to account progress, enforce budgets, and
  decide when to continue work.
  
  ## What changed
  
  - Centralized goal lifecycle side effects behind
  `Session::goal_runtime_apply(GoalRuntimeEvent::...)`.
  - Starts goal continuation turns only when the session is idle; pending
  user input and mailbox work take priority.
  - Accounts token and wall-clock usage at turn, tool, mutation,
  interrupt, and resume boundaries; `get_thread_goal` remains read-only.
  - Preserves sub-second wall-clock remainder across accounting boundaries
  so long-running goals do not drift downward over time.
  - Treats token budget exhaustion as a soft stop by marking the goal
  `budget_limited` and injecting wrap-up steering instead of aborting the
  active turn.
  - Suppresses budget steering when `update_goal` marks a goal complete.
  - Pauses active goals on interrupt and auto-reactivates paused goals
  when a thread resumes outside plan mode.
  - Suppresses repeated automatic continuation when a continuation turn
  makes no tool calls.
  - Added continuation and budget-limit prompt templates.
  
  ## Verification
  
  - Added focused core coverage for continuation scheduling, accounting
  boundaries, budget-limit steering, completion accounting, interrupt
  pause behavior, resume auto-activation, and wall-clock remainder
  accounting.

• Add goal app-server API (2 / 5) (#18074)

  Adds the app-server v2 goal API on top of the persisted goal state from
  PR 1.
  
  ## Why
  
  Clients need a stable app-server surface for reading and controlling
  materialized thread goals before the model tools and TUI can use them.
  Goal changes also need to be observable by app-server clients, including
  clients that resume an existing thread.
  
  ## What changed
  
  - Added v2 `thread/goal/get`, `thread/goal/set`, and `thread/goal/clear`
  RPCs for materialized threads.
  - Added `thread/goal/updated` and `thread/goal/cleared` notifications so
  clients can keep local goal state in sync.
  - Added resume/snapshot wiring so reconnecting clients see the current
  goal state for a thread.
  - Added app-server handlers that reconcile persisted rollout state
  before direct goal mutations.
  - Updated the app-server README plus generated JSON and TypeScript
  schema fixtures for the new API surface.
  
  ## Verification
  
  - Added app-server v2 coverage for goal get/set/clear behavior,
  notification emission, resume snapshots, and non-local thread-store
  interactions.

• [codex] add non-local thread store regression harness (#19266)

  - Add an integration test that guarantees nothing gets written to codex
  home dir or sqlite when running a rollout with a non-local ThreadStore
  - Add an in-memory "spy" ThreadStore for tests like this
  
  Note I could not find a good way to also ensure there were no filesystem
  _reads_ that didn't go through threadstore. I explored a more elaborate
  sandboxed-subprocess approach but it isn't platform portable and felt
  like it wasn't (yet) worth it.

• permissions: make legacy profile conversion cwd-free (#19414)

  ## Why
  
  The profile conversion path still required a `cwd` even when it was only
  translating a legacy `SandboxPolicy` into a `PermissionProfile`. That
  made profile producers invent an ambient `cwd`, which is exactly the
  anchoring we are trying to remove from permission-profile data. A legacy
  workspace-write policy can be represented symbolically instead: `:cwd =
  write` plus read-only `:project_roots` metadata subpaths.
  
  This PR creates that cwd-free base so the rest of the stack can stop
  threading cwd through profile construction. Callers that actually need a
  concrete runtime filesystem policy for a specific cwd still have an
  explicitly named cwd-bound conversion.
  
  ## What Changed
  
  - `PermissionProfile::from_legacy_sandbox_policy` now takes only
  `&SandboxPolicy`.
  - `FileSystemSandboxPolicy::from_legacy_sandbox_policy` is now the
  symbolic, cwd-free projection for profiles.
  - The old concrete projection is retained as
  `FileSystemSandboxPolicy::from_legacy_sandbox_policy_for_cwd` for
  runtime/boundary code that must materialize legacy cwd behavior.
  - Workspace-write profiles preserve `CurrentWorkingDirectory` and
  `ProjectRoots` special entries instead of materializing cwd into
  absolute paths.
  
  ## Verification
  
  - `cargo check -p codex-protocol -p codex-core -p
  codex-app-server-protocol -p codex-app-server -p codex-exec -p
  codex-exec-server -p codex-tui -p codex-sandboxing -p

• [codex] Omit fork turns from thread started notifications (#19093)

  ## Why
  
  `thread/fork` responses intentionally include copied history so the
  caller can render the fork immediately, but `thread/started` is a
  lifecycle notification. The v2 `Thread` contract says notifications
  should return `turns: []`, and the fork path was reusing the response
  thread directly, causing copied turns to be emitted through
  `thread/started` as well.
  
  ## What Changed
  
  - Route app-server `thread/started` notification construction through a
  helper that clears `thread.turns` before sending.
  - Keep `thread/fork` responses unchanged so callers still receive copied
  history.
  - Add persistent and ephemeral fork coverage that asserts
  `thread/started` emits an empty `turns` array while the response retains
  fork history.
  
  ## Testing
  
  - `just fmt`
  - `cargo test -p codex-app-server`

• Fix hang on turn/interrupt (#18392)

  Fix a bug where the `turn/interrupt` RPC hangs when interrupting a turn
  that has already completed.
  
  Before this change, `turn/interrupt` requests were queued in app-server
  and only answered when a later TurnAborted event arrived. If the target
  turn was already complete, core treated Op::Interrupt as a no-op, so no
  abort event was emitted and the RPC could hang indefinitely.
  
  This change fixes that in two places:
  
  * Reject turn/interrupt immediately with `INVALID_REQUEST` when the
  requested turn is no longer the active turn.
  * Resolve any already-accepted pending interrupt requests when the turn
  reaches TurnComplete, covering the case where a turn finishes naturally
  after the interrupt request is accepted but before it aborts.
  
  I tested this by adding a failing test in
  707487c0634834f6741986b64f61886c2dc10108. You may view the results here:

• permissions: make profiles represent enforcement (#19231)

  ## Why
  
  `PermissionProfile` is becoming the canonical permissions abstraction,
  but the old shape only carried optional filesystem and network fields.
  It could describe allowed access, but not who is responsible for
  enforcing it. That made `DangerFullAccess` and `ExternalSandbox` lossy
  when profiles were exported, cached, or round-tripped through app-server
  APIs.
  
  The important model change is that active permissions are now a disjoint
  union over the enforcement mode. Conceptually:
  
  ```rust
  pub enum PermissionProfile {
      Managed {
          file_system: FileSystemSandboxPolicy,
          network: NetworkSandboxPolicy,
      },
      Disabled,
      External {
          network: NetworkSandboxPolicy,
      },
  }
  ```
  
  This distinction matters because `Disabled` means Codex should apply no
  outer sandbox at all, while `External` means filesystem isolation is
  owned by an outside caller. Those are not equivalent to a broad managed
  sandbox. For example, macOS cannot nest Seatbelt inside Seatbelt, so an
  inner sandbox may require the outer Codex layer to use no sandbox rather
  than a permissive one.
  
  ## How Existing Modeling Maps
  
  Legacy `SandboxPolicy` remains a boundary projection, but it now maps
  into the higher-fidelity profile model:
  
  - `ReadOnly` and `WorkspaceWrite` map to `PermissionProfile::Managed`
  with restricted filesystem entries plus the corresponding network
  policy.
  - `DangerFullAccess` maps to `PermissionProfile::Disabled`, preserving
  the “no outer sandbox” intent instead of treating it as a lax managed
  sandbox.
  - `ExternalSandbox { network_access }` maps to
  `PermissionProfile::External { network }`, preserving external
  filesystem enforcement while still carrying the active network policy.
  - Split runtime policies that legacy `SandboxPolicy` cannot faithfully
  express, such as managed unrestricted filesystem plus restricted
  network, stay `Managed` instead of being collapsed into
  `ExternalSandbox`.
  - Per-command/session/turn grants remain partial overlays via
  `AdditionalPermissionProfile`; full `PermissionProfile` is reserved for
  complete active runtime permissions.
  
  ## What Changed
  
  - Change active `PermissionProfile` into a tagged union: `managed`,
  `disabled`, and `external`.
  - Keep partial permission grants separate with
  `AdditionalPermissionProfile` for command/session/turn overlays.
  - Represent managed filesystem permissions as either `restricted`
  entries or `unrestricted`; `glob_scan_max_depth` is non-zero when
  present.
  - Preserve old rollout compatibility by accepting the pre-tagged `{
  network, file_system }` profile shape during deserialization.
  - Preserve fidelity for important edge cases: `DangerFullAccess`
  round-trips as `disabled`, `ExternalSandbox` round-trips as `external`,
  and managed unrestricted filesystem + restricted network stays managed
  instead of being mistaken for external enforcement.
  - Preserve configured deny-read entries and bounded glob scan depth when
  full profiles are projected back into runtime policies, including
  unrestricted replacements that now become `:root = write` plus deny
  entries.
  - Regenerate the experimental app-server v2 JSON/TypeScript schema and
  update the `command/exec` README example for the tagged
  `permissionProfile` shape.
  
  ## Compatibility
  
  Legacy `SandboxPolicy` remains available at config/API boundaries as the
  compatibility projection. Existing rollout lines with the old
  `PermissionProfile` shape continue to load. The app-server
  `permissionProfile` field is experimental, so its v2 wire shape is
  intentionally updated to match the higher-fidelity model.
  
  ## Verification
  
  - `just write-app-server-schema`
  - `cargo check --tests`
  - `cargo test -p codex-protocol permission_profile`

• feat: let model providers own model discovery (#18950)

  ## Why
  
  `codex-models-manager` had grown to own provider-specific concerns:
  constructing OpenAI-compatible `/models` requests, resolving provider
  auth, emitting request telemetry, and deciding how provider catalogs
  should be sourced. That made the manager harder to reuse for providers
  whose model catalog is not fetched from the OpenAI `/models` endpoint,
  such as Amazon Bedrock.
  
  This change moves provider-specific model discovery behind
  provider-owned implementations, so the models manager can focus on
  refresh policy, cache behavior, picker ordering, and model metadata
  merging.
  
  ## What Changed
  
  - Introduced a `ModelsManager` trait with separate `OpenAiModelsManager`
  and `StaticModelsManager` implementations.
  - Added `ModelsEndpointClient` so OpenAI-compatible HTTP fetching lives
  outside `codex-models-manager`.
  - Moved `/models` request construction, provider auth resolution,
  timeout handling, and request telemetry into `codex-model-provider` via
  `OpenAiModelsEndpoint`.
  - Added provider-owned `models_manager(...)` construction so configured
  OpenAI-compatible providers use `OpenAiModelsManager`, while
  static/catalog-backed providers can return `StaticModelsManager`.
  - Added an Amazon Bedrock static model catalog for the GPT OSS Bedrock
  model IDs.
  - Updated core/session/thread manager code and tests to depend on
  `Arc<dyn ModelsManager>`.
  - Moved offline model test helpers into
  `codex_models_manager::test_support`.
  ## Metadata References
  
  The Bedrock catalog metadata is based on the official Amazon Bedrock
  OpenAI model documentation:
  
  - [Amazon Bedrock OpenAI
  models](https://docs.aws.amazon.com/bedrock/latest/userguide/model-parameters-openai.html)
  lists the Bedrock model IDs, text input/output modalities, and `128,000`
  token context window for `gpt-oss-20b` and `gpt-oss-120b`.
  - [Amazon Bedrock `gpt-oss-120b` model
  card](https://docs.aws.amazon.com/bedrock/latest/userguide/model-card-openai-gpt-oss-120b.html)
  lists the `bedrock-runtime` model ID `openai.gpt-oss-120b-1:0`, the
  `bedrock-mantle` model ID `openai.gpt-oss-120b`, text-only modalities,
  and `128K` context window.
  - [OpenAI `gpt-oss-120b` model
  docs](https://developers.openai.com/api/docs/models/gpt-oss-120b)
  document configurable reasoning effort with `low`, `medium`, and `high`,
  plus text input/output modality.
  
  The display names, default reasoning effort, and priority ordering are
  Codex-local catalog choices.
  
  ## Test Plan
  - Manually verified app-server model listing with an AWS profile:
  
  ```shell
  CODEX_HOME="$(mktemp -d)" cargo run -p codex-app-server-test-client -- \
    --codex-bin ./target/debug/codex \
    -c 'model_provider="amazon-bedrock"' \
    -c 'model_providers.amazon-bedrock.aws.profile="codex-bedrock"' \
    -c 'model_providers.amazon-bedrock.aws.region="us-west-2"' \
    model-list
  ```
  
  The response returned the Bedrock catalog with `openai.gpt-oss-120b-1:0`
  as the default model and `openai.gpt-oss-20b-1:0` as the second listed
  model, both text-only and supporting low/medium/high reasoning effort.

• feat: expose AWS account state from account/read (#19048)

  ## Why
  
  AWS/Bedrock mode currently reports `account: null` with
  `requiresOpenaiAuth: false` from `account/read`. That suppresses the
  OpenAI-auth requirement, but it does not let app clients distinguish AWS
  auth from any other non-OpenAI custom provider. For the prototype AWS
  provider UX, clients need a simple provider-derived signal so they can
  suppress ChatGPT/API-key login and token-refresh paths without
  hardcoding Bedrock checks.
  
  ## What changed
  
  - Adds an `aws` variant to the v2 `Account` protocol union.
  - Adds `ProviderAccountKind` to `codex-model-provider` so the runtime
  provider owns the app-visible account classification.
  - Makes Amazon Bedrock return `ProviderAccountKind::Aws` from the
  model-provider layer.
  - Updates app-server `account/read` to map `ProviderAccountKind` to the
  existing `GetAccountResponse` wire shape.
  - Preserves the existing `account: null, requiresOpenaiAuth: false`
  behavior for other non-OpenAI providers.
  - Regenerates the app-server protocol schema fixtures.
  - Adds coverage for provider account classification and for the Amazon
  Bedrock `account/read` response.

• refactor: route Codex auth through AuthProvider (#18811)

  ## Summary
  
  This PR moves Codex backend request authentication from direct
  bearer-token handling to `AuthProvider`.
  
  The new `codex-auth-provider` crate defines the shared request-auth
  trait. `CodexAuth::provider()` returns a provider that can apply all
  headers needed for the selected auth mode.
  
  This lets ChatGPT token auth and AgentIdentity auth share the same
  callsite path:
  - ChatGPT token auth applies bearer auth plus account/FedRAMP headers
  where needed.
  - AgentIdentity auth applies AgentAssertion plus account/FedRAMP headers
  where needed.
  
  Reference old stack: https://github.com/openai/codex/pull/17387/changes
  
  ## Callsite Migration
  
  | Area | Change |
  | --- | --- |
  | backend-client | accepts an `AuthProvider` instead of a raw
  token/header |
  | chatgpt client/connectors | applies auth through
  `CodexAuth::provider()` |
  | cloud tasks | keeps Codex-backend gating, applies auth through
  provider |
  | cloud requirements | uses Codex-backend auth checks and provider
  headers |
  | app-server remote control | applies provider headers for backend calls
  |
  | MCP Apps/connectors | gates on `uses_codex_backend()` and keys caches
  from generic account getters |
  | model refresh | treats AgentIdentity as Codex-backend auth |
  | OpenAI file upload path | rejects non-Codex-backend auth before
  applying headers |
  | core client setup | keeps model-provider auth flow and allows
  AgentIdentity through provider-backed OpenAI auth |

• Respect explicit untrusted project config (#18626)

  ## Why
  
  Fixes #18475. A `-c` override such as `projects.<cwd>.trust_level =
  "untrusted"` is meant to be a runtime config override, but app-server
  thread startup treated any non-trusted project as eligible for automatic
  trust persistence when a permissive sandbox/cwd was requested. That
  meant an explicit `untrusted` session override could still cause
  `config.toml` to be updated with `trusted`.
  
  ## What changed
  
  The app-server auto-trust path now runs only when the active project
  trust level is unknown. Explicit `trusted` and explicit `untrusted`
  values are both respected, regardless of whether they came from
  persisted config or session flags.
  
  A focused `thread/start` test now covers the explicit `untrusted` case
  with a permissive sandbox request.

• Add excludeTurns parameter to thread/resume and thread/fork (#19014)

  For callers who expect to be paginating the results for the UI, they can
  now call thread/resume or thread/fork with excludeturns:true so it will
  not fetch any pages of turns, and instead only set up the subscription.
  That call can be immediately followed by pagination requests to
  thread/turns/list to fetch pages of turns according to the UI's current
  interactions.

• Clarify cloud requirements error messages (#19078)

  ## Why
  The current cloud-requirements failures say `workspace-managed config`,
  which is ambiguous and can read like it refers to local managed config
  such as `managed_config.toml`.
  
  This code path only applies to cloud requirements, so the user-facing
  message should name that source directly.
  
  ## What changed
  - Updated the load failure in
  [`codex-rs/cloud-requirements/src/lib.rs`](https://github.com/openai/codex/blob/46e704d1f93054daa9a3b5a9100333c540c81d50/codex-rs/cloud-requirements/src/lib.rs)
  to say `failed to load cloud requirements (workspace-managed policies)`.
  - Updated the parse failure in the same file to use the same `cloud
  requirements (workspace-managed policies)` terminology.
  - Kept `workspace-managed` hyphenated because it is used as a compound
  modifier.
  - Updated the matching assertion in
  [`codex-rs/app-server/src/codex_message_processor.rs`](https://github.com/openai/codex/blob/46e704d1f93054daa9a3b5a9100333c540c81d50/codex-rs/app-server/src/codex_message_processor.rs).
  - Reused `CLOUD_REQUIREMENTS_LOAD_FAILED_MESSAGE` in the
  `codex-cloud-requirements` test where the test is asserting that
  crate-local contract directly.
  
  ## Testing
  `cargo test -p codex-cloud-requirements`

• app-server: accept command permission profiles (#18283)

  ## Why
  
  `command/exec` is another app-server entry point that can run under
  caller-provided permissions. It needs to accept `PermissionProfile`
  directly so command execution is not left behind on `SandboxPolicy`
  while thread APIs move forward.
  
  Command-level profiles also need to preserve the semantics clients
  expect from profile-relative paths. `:cwd` and cwd-relative deny globs
  should be anchored to the resolved command cwd for a command-specific
  profile, while configured deny-read restrictions such as `**/*.env =
  none` still need to be enforced because they can come from config or
  requirements rather than the command override itself.
  
  ## What Changed
  
  This adds `permissionProfile` to `CommandExecParams`, rejects requests
  that combine it with `sandboxPolicy`, and converts accepted profiles
  into the runtime filesystem/network permissions used for command
  execution.
  
  When a command supplies a profile, the app-server resolves that profile
  against the command cwd instead of the thread/server cwd. It also
  preserves configured deny-read entries and `globScanMaxDepth` on the
  effective filesystem policy so one-off command overrides cannot drop
  those read protections. The PR also updates app-server docs/schema
  fixtures and adds command-exec coverage for accepted, rejected,
  cwd-scoped, and deny-read-preserving profile paths.
  
  ## Verification
  
  - `cargo test -p codex-app-server
  command_exec_permission_profile_cwd_uses_command_cwd`
  - `cargo test -p codex-app-server
  command_profile_preserves_configured_deny_read_restrictions`

• app-server: accept permission profile overrides (#18279)

  ## Why
  
  `PermissionProfile` is becoming the canonical permissions shape shared
  by core and app-server. After app-server responses expose the active
  profile, clients need to be able to send that same shape back when
  starting, resuming, forking, or overriding a turn instead of translating
  through the legacy `sandbox`/`sandboxPolicy` shorthands.
  
  This still needs to preserve the existing requirements/platform
  enforcement model. A profile-shaped request can be downgraded or
  rejected by constraints, but the server should keep the user's
  elevated-access intent for project trust decisions. Turn-level profile
  overrides also need to retain existing read protections, including
  deny-read entries and bounded glob-scan metadata, so a permission
  override cannot accidentally drop configured protections such as
  `**/*.env = deny`.
  
  ## What changed
  
  - Adds optional `permissionProfile` request fields to `thread/start`,
  `thread/resume`, `thread/fork`, and `turn/start`.
  - Rejects ambiguous requests that specify both `permissionProfile` and
  the legacy `sandbox`/`sandboxPolicy` fields, including running-thread
  resume requests.
  - Converts profile-shaped overrides into core runtime filesystem/network
  permissions while continuing to derive the constrained legacy sandbox
  projection used by existing execution paths.
  - Preserves project-trust intent for profile overrides that are
  equivalent to workspace-write or full-access sandbox requests.
  - Preserves existing deny-read entries and `globScanMaxDepth` when
  applying turn-level `permissionProfile` overrides.
  - Updates app-server docs plus generated JSON/TypeScript schema fixtures
  and regression coverage.
  
  ## Verification
  
  - `cargo test -p codex-app-server-protocol schema_fixtures`
  - `cargo test -p codex-core
  session_configuration_apply_permission_profile_preserves_existing_deny_read_entries`

• Add plumbing to approve stored Auto-Review denials (#18955)

  ## Summary
  
  This adds the structural plumbing needed for an app-server client to
  approve a previously denied Guardian review and carry that approval
  context into the next model turn.
  
  This PR does not add the actual `/auto-review-denials` tool 
  
  ## What Changed
  
  - Added app-server v2 RPC `thread/approveGuardianDeniedAction`.
  - Added generated JSON schema and TypeScript fixtures for
  `ThreadApproveGuardianDeniedAction*`.
  - Added core `Op::ApproveGuardianDeniedAction`.
  - Added a core handler that validates the event is a denied Guardian
  assessment and injects a developer message containing the stored denial
  event JSON.
  - Queues the approval context for the next turn if there is no active
  turn yet.
  - Added the TUI app-server bridge so `Op::ApproveGuardianDeniedAction {
  event }` is routed to the app-server request.
  
  ## What This Does Not Do
  
  - Does not add `/auto-review-denials`.
  - Does not add chat widget recent-denial state.
  - Does not add popup/list UI.
  - Does not add a product-facing denial lookup/store.
  - Does not change where Guardian denials are originally emitted or
  persisted.
  
  ## Verification
  
  - `cargo test -p codex-tui thread_approve_guardian_denied_action`

• Support multiple cwd filters for thread list (#18502)

  ## Summary
  
  - Teach app-server `thread/list` to accept either a single `cwd` or an
  array of cwd filters, returning threads whose recorded session cwd
  matches any requested path
  - Add `useStateDbOnly` as an explicit opt-in fast path for callers that
  want to answer `thread/list` from SQLite without scanning JSONL rollout
  files
  - Preserve backwards compatibility: by default, `thread/list` still
  scans JSONL rollouts and repairs SQLite state
  - Wire the new cwd array and SQLite-only options through app-server,
  local/remote thread-store, rollout listing, generated TypeScript/schema
  fixtures, proto output, and docs
  
  ## Test Plan
  
  - `cargo test -p codex-app-server-protocol`
  - `cargo test -p codex-rollout`
  - `cargo test -p codex-thread-store`
  - `cargo test -p codex-app-server thread_list`
  - `just fmt`
  - `just fix -p codex-app-server-protocol -p codex-rollout -p
  codex-thread-store -p codex-app-server`
  - `cargo build -p codex-cli --bin codex`

• app-server: expose thread permission profiles (#18278)

  ## Why
  
  The `PermissionProfile` migration needs app-server clients to see the
  same constrained permission model that core is using at runtime. Before
  this PR, thread lifecycle responses only exposed the legacy
  `SandboxPolicy` shape, so clients still had to infer active permissions
  from sandbox fields. That makes downstream resume, fork, and override
  flows harder to make `PermissionProfile`-first.
  
  External sandbox policies are intentionally excluded from this canonical
  view. External enforcement cannot be round-tripped as a
  `PermissionProfile`, and exposing a lossy root-write profile would let
  clients accidentally change sandbox semantics if they echo the profile
  back later.
  
  ## What changed
  
  - Adds the app-server v2 `PermissionProfile` wire shape, including
  filesystem permissions and glob scan depth metadata.
  - Adds `PermissionProfileNetworkPermissions` so the profile response
  does not expose active network state through the older
  additional-permissions naming.
  - Returns `permissionProfile` from thread start, resume, and fork
  responses when the active sandbox can be represented as a
  `PermissionProfile`.
  - Keeps legacy `sandbox` in those responses for compatibility and
  documents `permissionProfile` as canonical when present.
  - Makes lifecycle `permissionProfile` nullable and returns `null` for
  `ExternalSandbox` to avoid exposing a lossy profile.
  - Regenerates the app-server JSON schema and TypeScript fixtures.
  
  ## Verification
  
  - `cargo test -p codex-app-server-protocol`
  - `cargo test -p codex-app-server
  thread_response_permission_profile_omits_external_sandbox --
  --nocapture`
  - `cargo check --tests -p codex-analytics -p codex-exec -p codex-tui`
  - `just fix -p codex-app-server-protocol -p codex-app-server -p

• feat: add explicit AgentIdentity auth mode (#18785)

  ## Summary
  
  This PR adds `CodexAuth::AgentIdentity` as an explicit auth mode.
  
  An AgentIdentity auth record is a standalone `auth.json` mode. When
  `AuthManager::auth().await` loads that mode, it registers one
  process-scoped task and stores it in runtime-only state on the auth
  value. Header creation stays synchronous after that because the task is
  initialized before callers receive the auth object.
  
  This PR also removes the old feature flag path. AgentIdentity is
  selected by explicit auth mode, not by a hidden flag or lazy mutation of
  ChatGPT auth records.
  
  Reference old stack: https://github.com/openai/codex/pull/17387/changes
  
  ## Design Decisions
  
  - AgentIdentity is a real auth enum variant because it can be the only
  credential in `auth.json`.
  - The process task is ephemeral runtime state. It is not serialized and
  is not stored in rollout/session data.
  - Account/user metadata needed by existing Codex backend checks lives on
  the AgentIdentity record for now.
  - `is_chatgpt_auth()` remains token-specific.
  - `uses_codex_backend()` is the broader predicate for ChatGPT-token auth
  and AgentIdentity auth.
  
  ## Stack
  
  1. https://github.com/openai/codex/pull/18757: full revert
  2. https://github.com/openai/codex/pull/18871: isolated Agent Identity

• core: derive active permission profiles (#18277)

  ## Why
  
  `Permissions` should not store a separate `PermissionProfile` that can
  drift from the constrained `SandboxPolicy` and network settings. The
  active profile needs to be derived from the same constrained values that
  already honor `requirements.toml`.
  
  ## What changed
  
  This adds derivation of the active `PermissionProfile` from the
  constrained runtime permission settings and exposes that derived value
  through config snapshots and thread state. The app-server can then
  report the active profile without introducing a second source of truth.
  
  ## Verification

  --nocapture`
  - `cargo test -p codex-core --test all request_permissions --

• fix: fully revert agent identity runtime wiring (#18757)

  ## Summary
  
  This PR fully reverts the previously merged Agent Identity runtime
  integration from the old stack:
  https://github.com/openai/codex/pull/17387/changes
  
  It removes the Codex-side task lifecycle wiring, rollout/session
  persistence, feature flag plumbing, lazy `auth.json` mutation,
  background task auth paths, and request callsite changes introduced by
  that stack.
  
  This leaves the repo in a clean pre-AgentIdentity integration state so
  the follow-up PRs can reintroduce the pieces in smaller reviewable
  layers.
  
  ## Stack
  
  1. This PR: full revert
  2. https://github.com/openai/codex/pull/18871: move Agent Identity
  business logic into a crate
  3. https://github.com/openai/codex/pull/18785: add explicit
  AgentIdentity auth mode and startup task allocation
  4. https://github.com/openai/codex/pull/18811: migrate auth callsites
  through AuthProvider
