## What changed
Add the disabled-by-default `reasoning_effort_override` feature for OpenAI models with `use_responses_lite` enabled. Append a trusted `configuration_update` after accepted input when no effort is established in surviving history or the resolved effort changes. Preserve the existing history prefix and continue sending the request-level reasoning effort.
Share effort normalization through `ModelInfo::resolve_reasoning_effort` so requests and history updates resolve `ultra` consistently and translate `persistent` to `disabled`. Exclude other custom effort values from history updates, and compare only against harness-authored configuration items.
## Testing
Add integration coverage for effort transitions, deduplication, history prefix and cache-key preservation, alias normalization, and feature/provider/model gating. Add unit coverage for model-specific `ultra` resolution, fallbacks, and `persistent` translation.

## What changed
Replace `features.guardian_thread_context` with `features.guardianv2.thread_context` and update the configuration schema. The setting controls thread-owned context for synchronous and asynchronous Guardian, defaults to `false`, and remains independent of `features.guardianv2.enabled`.
## Testing
Update configuration tests to cover the nested setting, profile overrides, and enabling thread context while Guardian v2 is disabled. Migrate Guardian approval, history, and async scorer tests to the new configuration key.
GitOrigin-RevId: 54a91555eb68001e0adedc8a07bdbc5ea2273f9b
## What changed
- Add the stable, default-on `unified_exec_tty` feature.
- When disabled, omit `tty` from the `exec_command` tool schema and reject calls that explicitly request a TTY.
- Continue to support commands that omit `tty` or set it to `false`.
## Testing
- Add unified exec coverage for the disabled tool schema, explicit TTY rejection, and non-TTY command execution.
GitOrigin-RevId: c5934fe9db1423170b891c7ecd0188792cd03f42
## What changed
- Add the experimental `worktrees` feature and a shared `--worktree` flag for new and forked `codex exec` sessions.
- Create each enabled session in a managed Git worktree, use that checkout as the session working directory, and bind the checkout to the new thread.
- Share the configured worktree pool with Desktop while leaving automatic cleanup disabled for CLI allocations.
- Reject unsupported commands, remote execution, ignored user configuration, ephemeral sessions, and use without the feature enabled before allocating a worktree.
## Testing
- Cover flag placement and inheritance, supported and rejected command combinations, worktree allocation and thread ownership, configuration gating, and compatibility with existing worktree-backed sessions.
GitOrigin-RevId: 011ff4639b09e8992c50d7b823df23e71798670e
## Why
Guardian authorization reviews need host-verified `request_user_input` answers to
remain aligned with thread history across compaction, resume, and rollback.
## What changed
- Record verified question-and-answer pairs in retained thread context when
`GuardianThreadContext` is enabled, and source both local and delegated Guardian
review evidence from that context.
- Preserve complete answer records within the evidence budget. Mark authorization
context incomplete when records are unavailable or oversized, and defer cached
fast approvals in that case.
- Keep the existing runtime-only answer path for threads that do not enable the
thread-owned context.
## Testing
- Cover answer retention through compaction and resume, removal after rollback,
source-call eviction, oversized answers, delegated review evidence, and legacy
behavior.
GitOrigin-RevId: 01f6f4541515434a0d00fdde318ff59f2f8bd2eb
## What changed
- Add the disabled, under-development `guardian_thread_context` feature flag for selecting thread-owned context for Guardian reviewers.
- Expose the boolean setting in the generated configuration schema.
- Verify default, base configuration, and profile override resolution.
GitOrigin-RevId: c4878be96d12f4ccd84356df15d3e55f13ac141f
## What changed
- Add the under-development `features.context_management.experimental_mode` configuration and schema.
- For eligible ChatGPT Plus, Pro, and Pro Lite sessions using the Codex backend, enable token-budget context, history notes, and the `new_context` tool when experimental context management is configured.
- Keep the feature disabled for custom providers, provider credentials, non-Codex endpoints, and temporary structured threads.
## Testing
- Cover subscription eligibility, backend restrictions, configuration resolution, token-budget guidance, and temporary-thread overrides.
GitOrigin-RevId: 19402af19c4d69e09a7cdb3687ee7d233f6a562a
## What changed
- Remove the per-thread `RealtimeConversation` feature check when starting a realtime session.
- Retain `features.realtime_conversation` as a removed compatibility setting that has no effect, even when set to `false`.
- Document the always-available behavior for `thread/realtime/start`.
## Testing
- Cover realtime startup on forked and cold-resumed threads with the legacy setting absent, disabled, or enabled.
GitOrigin-RevId: d9cd9aa3898d1c2efb9414a8f40c86be8951e210
## What changed
- Add the default-off `windows_sandbox_service` feature and expose it through
app-server experimental feature enablement.
- When enabled, attempt service provisioning during elevated Windows sandbox
setup, using the effective network proxy ports and listener roles. Continue
through the existing setup path when the service is unavailable or the
configuration is unsupported.
- Report unsupported Codex home drives as service unavailability so the client
can fall back to the elevated helper.
## Testing
- Add a Windows-only unit test covering HTTP and SOCKS listener derivation from
the effective proxy configuration.
GitOrigin-RevId: 40b119cf51f84e5d0e94d6a0a8d5b506d1123526
## What changed
- Add the under-development `mcp_oauth_refresh_coordination` feature and pin its selected refresh mode to each MCP connection.
- Treat the refresh mode as part of OAuth connection identity so runtime and MCP configuration refreshes reconnect when the mode changes.
- Keep legacy refresh behavior in builds where coordination is unavailable and emit a warning when coordinated mode is selected.
## Testing
- Cover connection replacement when the feature is toggled through both runtime and MCP configuration refresh paths.
GitOrigin-RevId: 89596150f0338e6ede0e712badecea4450831766
## What changed
- Make `local_thread_store_compression` compress cold rollout files across shared and forked histories without a separate compression mode.
- Retire `local_thread_store_shared_compression` while continuing to accept it in strict configuration without changing compression behavior.
- Read rollout files through the compressed-rollout reader when `codex exec resume` determines the latest turn's working directory.
## Testing
- Cover compression and restoration of an archived fork chain.
- Cover cwd-based resume selection when only the compressed rollout remains.
- Cover the removed compatibility key in strict configuration.
GitOrigin-RevId: 8edebf61eccc1f79cabb8e641f8982c76f337bf1
## What changed
- Add the disabled-by-default `omit_app_server_notification_media` feature.
- When enabled, remove inline image and audio content from `item/started`,
`item/completed`, and `rawResponseItem/completed` notifications, including
tool output and image-generation results.
- Keep the media in model input; the filter only changes app-server
notifications.
## Testing
- Verify that image content is absent from all three notification types while
the model request still receives it.
GitOrigin-RevId: 9a4434d18a3dac6d67c2e0c3723ff4595a9b3797
## Why
Fetching plugin recommendations while building the first-turn context delays that
context when the recommendation catalog is not already cached.
## What changed
- Start fetching recommendations during session initialization, in parallel with
MCP and plugin setup, and reuse the in-flight request when building context.
- Centralize the feature checks that enable plugin recommendations.
- Prevent an invalidated recommendation request from repopulating the cache after
a newer request has completed.
## Testing
Added coverage for startup feature gating, reuse of the in-flight fetch, legacy
behavior when recommendations are unavailable, and cache invalidation races.
GitOrigin-RevId: 708774b9bfc472c9847973ae8b2774b66e7321e4
## Why
Rollout compression skips files that participate in paginated fork lineages because lineage readers rely on byte offsets into the original JSONL. This prevents shared rollout history from being compressed.
## What changed
- Add a seekable rollout reader that preserves logical JSONL offsets for plain and zstd-compressed files without materializing compressed data beside the rollout.
- Use the reader for lineage validation, model-context replay, and SQLite history projection, including when compression races with a read.
- Add the opt-in `local_thread_store_shared_compression` feature. The default mode continues to leave shared lineages uncompressed for compatibility, while the new mode includes referenced sources and fork pointers.
- Record the uncompressed size in new zstd frames so common prefix-bound checks can avoid decoding the full file.
## Testing
Add coverage for seekable compressed reads, prefix validation across zstd frame shapes, compressed lineage replay and projection, concurrent forks, and compression-mode behavior.
GitOrigin-RevId: 83e519f7eabf7448977eff37c55899858cc17a07
## What changed
- Add a stable `sleep_tool` feature that can enable or disable registration of the built-in sleep tool independently of the clock tool.
- Support structured `features.sleep_tool` configuration with `model_driven` and `always_on` modes. The default `model_driven` mode preserves the existing model and `current_time_reminder` behavior, while `always_on` registers sleep whenever the feature is enabled.
- Preserve nested sleep-tool configuration across CLI overrides, config merges, and feature toggles, and expose the settings in the generated config schema.
## Testing
- Cover feature-map overrides, both selection modes, legacy clock settings, config merging and editing, and invalid mode rejection.
GitOrigin-RevId: 18eadc582f8a4445958c29d063e5be495276703e
## What changed
- Add the under-development `powershell_shell_version` feature flag.
- When enabled for a single local PowerShell environment, query the selected
shell executable and include its major/minor version in
`<environment_context>`.
- Cache version lookups, bound command execution and output, and report when a
previously visible version becomes unavailable.
## Testing
- Cover environment-context diffs when the shell version appears or disappears.
- Verify on Windows that the version is model-visible only when the feature is
enabled.
GitOrigin-RevId: 3ec8e80425ec3c193134dc1b69f61ef09ede375e
## What changed
- Promote `compaction_image_budget` to stable and enable it by default.
- Charge retained images against the remote compaction context budget unless the feature is explicitly disabled, trimming older images as needed.
## Testing
- Update remote compaction coverage for the default, explicitly enabled, and explicitly disabled behavior.
GitOrigin-RevId: 0f715347cefc33b814bdcfd9b430ef453d3bd6df
## What changed
- Add the `write_stdin_approval` feature flag, disabled by default, to require a fresh approval before sending non-empty input to an escalated unified-exec terminal.
- Route these reviews through hooks, Guardian, app-server, and the TUI as `writeStdin` approvals while keeping the parent command item unchanged.
- Preserve the terminal environment, launch directory, and escalation state across turns, and revalidate the process identity after approval before writing input.
## Testing
- Cover approval routing, policy decisions, process reuse, terminal identity preservation, app-server events, analytics, and TUI rendering.
GitOrigin-RevId: 4ba29eaae6208e934737ba078c96e589c7c2164d
## What changed
- Add the `features.guardianv2.persist_scores` configuration option for debugging.
- Default the option to `false`, so Guardian V2 reviewed actions and risk scores are only written to rollout files when explicitly enabled and the session is not ephemeral.
## Testing
- Cover configuration deserialization, default non-persistence, and opt-in persistence for nested code-mode actions.
GitOrigin-RevId: 452af99ef14553d45140340ececc2913389124d0
## What changed
- Add the opt-in `features.guardianv2.free_guardian` setting to route eligible
Guardian reviews to `/guardian` and asynchronous classifications to
`/guardian-classifier`.
- Support endpoint selection for both HTTP and WebSocket Responses clients,
including endpoint-aware connection reuse.
- Keep `/responses` for API-key authentication, custom provider URLs,
non-Guardian models, and configurations where the option is disabled.
- Omit routing hints and `service_tier` from requests sent to the dedicated
Guardian endpoints.
## Testing
- Cover route selection across authentication modes, provider URLs, HTTP
fallback, WebSocket review sessions, and classifier sampling.
GitOrigin-RevId: 9c88673c710d009e0239559b9245a4e6c4f4befc
## What changed
- Add a feature-gated Amazon Bedrock option to eligible TUI sign-in flows.
- Discover existing AWS profiles and environment credentials, with manual setup for profiles, access keys, environment variables, and Bedrock API keys.
- Collect the AWS Region, mask secrets during entry, persist the selected Bedrock configuration through the app server, and restart the embedded server when the provider changes.
## Testing
- Cover wizard eligibility, sign-in option rendering, credential discovery ordering, region entry, and secret masking.
GitOrigin-RevId: 0a49afb6aca442b88e8448efa80336777848f4ac
## What changed
- Add the opt-in `code_mode_prewarm` feature to establish the code-mode host session during startup, before the first turn.
- Make in-progress host initialization cancellable so a stalled prewarm does not block shutdown.
- Share a failed connection attempt with concurrent callers instead of immediately starting another attempt.
## Testing
- Verify app-server contacts the configured host before the first turn and can shut down while that connection is stalled.
- Exercise shared remote-host behavior with prewarming enabled.
GitOrigin-RevId: 3cfde5509be7b4aba80112c36c5616b9a9b632c6
## What changed
Mark `content_item_kinds` as stable and enable it by default. Remove the
test harness override that previously enabled the feature explicitly.
GitOrigin-RevId: 86b0c3f295c4de3b8900981bfdd8830f275073f5
## What changed
- Add a feature-gated `TurnSettings` operation that can update the model,
reasoning effort, reasoning summary, and service tier for subsequent steps of
a named running turn without changing future thread settings.
- Report whether an update was applied, rejected, or lost its live target.
- Revalidate managed constraints and preserve the turn's admitted approval and
Guardian safety properties before publishing an updated settings snapshot.
## Testing
- Cover sparse updates, step capture and ordering, target replacement, managed
policy changes, model metadata safety, and separation from future settings.
GitOrigin-RevId: ecaaaa95b4fd4ec9d62265bef551582dddb36d78
## What changed
- Add the under-development `skip_host_skill_discovery` feature to bypass host
skill snapshots during session warmup and turn setup.
- Let skill invocation contributors declare whether they require host-owned
skills. Preserve host discovery when no contributors are registered or any
contributor requires it.
- Keep executor and orchestrator skill catalogs and instruction loading
available when host discovery is skipped.
## Testing
- Cover executor-only, orchestrator, mixed-contributor, and legacy host-skill
behavior.
GitOrigin-RevId: 48169403090b234e1a304c6523633fd867df454a
## What changed
- Add the under-development `transcript_v2` feature for the interactive
transcript composer and turn-selection UI.
- Keep it disabled by default and expose it through the configuration schema
and `codex features enable transcript_v2`.
## Testing
- Verify explicit configuration overrides and CLI persistence for the new
feature.
GitOrigin-RevId: 138ab7851621c066e8121cc3eb6cd4e7299f9c31
## What changed
- Add `features.guardianv2.review_scope.computer_use_only` to restrict asynchronous classification and fast approvals to browser and computer-use REPL tools.
- Keep other tools on the synchronous approval path without letting them age or reuse scores from in-scope calls.
- Give this scope precedence over `sandboxed_exec_commands` when both options are enabled.
## Testing
- Cover configuration precedence, direct and code-mode tool detection, fast-approval isolation, and end-to-end approval routing for browser, computer-use, and unrelated MCP servers.
GitOrigin-RevId: bfd9ab6abdbd90634b265d354e038724b1e81d65
## What changed
- Add `features.network_proxy.credential_broker` and preserve structured network proxy settings when toggling the feature through config APIs.
- Protect broker enablement and provider context variables from project config, while carrying trusted context into filtered shell environments.
- Propagate brokered credentials through shell snapshots and restore real credentials for unsandboxed escalated commands.
- Normalize broker context environment keys case-insensitively on Windows and avoid conflicting remote managed-network enforcement when no proxy launch configuration is available.
## Testing
- Cover config layering, editing, project sanitization, Windows environment handling, shell snapshots, escalated execution, and end-to-end GitHub credential brokering in the zsh-fork runtime.
GitOrigin-RevId: 500e51e804e1988022052ccfe00b8fac5e495f4f
## What changed
- Add the under-development `content_item_kinds` feature, disabled by default.
- Strip content item classifications from Responses input when the feature is
disabled while preserving other passthrough metadata.
## Testing
- Add coverage that disables the feature and verifies requests omit content item
kinds without removing the turn ID.

## What changed
- Register the stable, requirements-only `in_app_local_automation` feature for desktop apps.
- Add the feature to the configuration schema.
- Verify that an enterprise requirement can disable local automation.
GitOrigin-RevId: 939f7f3ee15f662dc85589cd1bcc3838e4cd1287
## Why
Remote compaction's retained-message budget counted text but not images, so
image-heavy history could retain more context than the budget represented.
## What changed
- Add the opt-in `compaction_image_budget` feature to charge retained images
using the existing image size estimate.
- Keep images and their adjacent labels atomic when truncating a boundary
message, while preserving existing text, audio, metadata, and
client-authored developer-message behavior.
- Stop backfilling older messages when an image at the truncation boundary
does not fit.
## Testing
- Add unit coverage for image boundaries, annotations, audio, text-only
messages, and client-authored developer messages.
- Add an integration test covering repeated remote compaction with the feature
enabled, disabled, and left at its default.
GitOrigin-RevId: 88868bbd09d2858939dbae3f8402e1f497b4e3c6
## What changed
- Recognize `cua_repl` alongside `node_repl` when collecting Guardian review evidence, applying computer-use policy, and capturing transcript images.
- Render `cua_repl.js` results with the compact REPL history and transcript views.
- Preserve failed MCP call status and result content when replaying app-server history.
## Testing
- Cover both REPL server names across Guardian policy, evidence, image capture, history rendering, and failed-call replay tests.
GitOrigin-RevId: 8c13a721f718add403b07e727c1634b59203c51a
## What changed
- Add an extension API for spawning host-owned internal sessions and a
`ThreadReadyInput` lifecycle callback that runs after thread registration.
- Add Guardian reviewer session scaffolding that records the parent thread and
effective model, plus the under-development `guardian_ext` feature flag.
- Start internal sessions with fresh history while preserving parent lineage,
shared session controls, and internal-thread visibility rules.
- Scope internal-session prompt cache keys to their source and parent thread,
and expose `guardian` as an internal session source.
## Testing
- Cover internal-session spawning, parent metadata, history isolation, prompt
cache keys, and extension spawner argument forwarding.
GitOrigin-RevId: 682dae80397d62bb36247796b447042e760ca364
## What changed
- Add the under-development `shell_snapshot_v2` feature and advertise executor support through environment capabilities.
- Use executor-managed, in-memory snapshots for eligible direct `bash`, `zsh`, and `sh` login commands, while applying the configured shell environment policy and avoiding duplicate automatic startup-file effects.
- Keep file-backed snapshots available for user-shell commands and fall back to the existing execution path when in-memory snapshots are unsupported or inapplicable.
## Testing
- Cover policy filtering, snapshot reuse without snapshot files, automatic startup files, local and remote execution, and legacy user-shell snapshots.
GitOrigin-RevId: 4ad6cdf13824913ac8c393ba38b9844230677579
## What changed
Rename the token-budget configuration key and its Rust field from
`use_history_notes_history` to `use_history_notes_extension`. Update the config
schema, extension gating, explicit-setting detection, and tests to use the new
name consistently.
GitOrigin-RevId: b6a514e23f02095fcd1d35dc42eeb7394b800c77
## Why
Token-budget sessions need a way to recover prior conversation context and preserve working state across context-window transitions.
## What changed
- Add direct-model `history` tools for listing windows and items, reading items, and searching conversation contents.
- Add direct-model `notes` tools for listing, reading, searching, appending, and writing persistent notes.
- Route tool calls through the configured Codex backend with trusted session and agent context, bounded request arguments, and truncation-aware output handling.
- Expose the extension when `features.token_budget.use_history_notes_history` is enabled with an OpenAI provider and Codex backend authentication.
## Testing
- Cover tool registration, configuration changes, provider and authentication requirements, backend request context, encrypted output preservation, and request and response limits.
GitOrigin-RevId: 43b259f01014ba3f30803dd7cd5634942407a9bb
## What changed
- Remove the legacy `shell_command` handler and runtime, leaving `exec_command`
and `write_stdin` as the shell execution tools.
- Treat legacy `shell_command` model metadata as `unified_exec`, and normalize
legacy user opt-outs so they do not disable command execution. Managed feature
requirements and `shell_tool` can still disable it.
- Preserve shell approvals, sandboxing, zsh-fork support, and output truncation
through the unified execution path.
## Testing
- Cover legacy configuration and model-metadata compatibility.
- Exercise unified shell execution, approvals, truncation, and `apply_patch`
serialization across the app-server and core test suites.
GitOrigin-RevId: 5c2fd6164fc3519cdae4944cb9db276b8467311c
## What changed
- Exclude sandboxed `exec_command` and `shell_command` calls from Guardian v2 classification by default while continuing to classify calls that request `require_escalated` permissions.
- Add `guardianv2.review_scope.sandboxed_exec_commands` to opt sandboxed shell commands back into classification.
- Keep other tools and namespaced shell tools in scope, and advance tool-call progress when a call is skipped.
## Testing
- Cover the default and configured review scopes, tool namespaces, permission modes, and skipped-call progress tracking.
GitOrigin-RevId: 32fb540c69959b9a82569f0f2fc76b5517496e6b
## What changed
- Add the opt-in `cwd_relative_turn_diffs` feature.
- When enabled, render turn diff paths relative to each selected environment's
working directory instead of the detected Git root.
- Preserve repository-root-relative paths when the feature is disabled.
## Testing
- Cover enabled and disabled behavior for nested working directories across
supported originators.
GitOrigin-RevId: 8b4908706a82b01f33ccd035b0945f9a29fce26f
## What changed
- Expose `send_user_message_async` to root agents whenever the selected model advertises support for it.
- Retain `send_async_message` as a removed compatibility flag so existing configuration is accepted without controlling tool availability.
- Update the async message test to cover model-driven tool exposure without enabling the legacy flag.
GitOrigin-RevId: 558b427c2b203a057dd7c836e0ec702ae6134346
## What changed
- Add the under-development `send_async_message` feature, disabled by default.

- Skip approval review when the score lags by more than `max_tool_call_lag` tool calls.
- Add `max_tool_call_lag` to the Guardian v2 configuration and schema, with a default of three.
## Testing
- Cover approval review at, above, and after recovering from the configured lag limit.
- Cover deserialization of `max_tool_call_lag`.
GitOrigin-RevId: fd870e143d95ee76491180e2aed742717248ff78
## What changed
- Add the `features.guardianv2.transcript.include_images` opt-in setting.

GitOrigin-RevId: b0ae6b6182535fd084ea103ed01dc3c803d7d1f7
## What changed
- Add `max_parent_compaction_tokens`, defaulting to 25,000 tokens, to the Guardian v2 feature configuration.
- Reuse the latest encrypted parent compaction only when its complete serialized item fits within the configured limit.
- Fail closed with the maximum action-risk score when the latest encrypted compaction is oversized, instead of sampling with older context.
## Testing
- Cover exact-boundary and oversized compaction items, including oversized passthrough metadata.
- Verify that an oversized latest compaction bypasses sampling and prevents approval.
GitOrigin-RevId: 0b308e7bec0f41d46433dfdf656948cee5cba667
## What changed
- Allow `features.guardianv2` to remain a boolean toggle or specify classifier instructions, the review threshold, reasoning effort, and action and instruction token limits.
- Add transcript controls for included sources, per-entry and total token budgets, and the number of recent non-user entries.
- Validate configured ranges and relationships, expose them in the generated config schema, and apply the resolved settings throughout Guardian v2 classification and approval review.
## Testing
- Cover boolean compatibility, configuration parsing and boundaries, config-manager rejection, and the resulting classifier request and approval decision.
GitOrigin-RevId: dc018b53b782e2d6b4d6a795cca4945130a71678
## What changed
- Enable the stable `unified_exec` feature by default on every platform.
- Update cross-platform integration test expectations so `exec_command` and
`write_stdin` are exposed on Windows instead of `shell_command`.
GitOrigin-RevId: e5c864bacbde7eab109e7a0e399b8f7b843b384c
## What changed
- Add the stable, default-enabled `unbounded_connection_retries` feature.

When disabled, connection failures use the existing bounded retry and
transport fallback path.
- Expose the feature in the generated configuration schema.
GitOrigin-RevId: bd80d02ef065ba924f805c29b639752fc817ed64
## What changed
- Preserve valid image content from completed `node_repl` Code Mode responses alongside text evidence for Guardian reviews.
- Enable multimodal evidence for models that require automatic `node_repl` review, or when both `guardian_enhanced_node_repl_transcripts` and `guardian_node_repl_transcript_images` are enabled.
- Bound retained and rendered evidence, deduplicate images already present in review history, and fall back to text-only evidence when the reviewer lacks image support or prompt capacity.
- Keep review evidence out of the parent turn input.
## Testing
- Cover feature gating, mixed text and image ordering, truncation and eviction, unsupported reviewers, prompt pressure, image detail normalization, and reused review sessions.
GitOrigin-RevId: a3e482402f7b3484401b231dadc662e6e3504fdf
