feat(app-server): add history_mode to thread (#29927)
## Description This PR adds a new `historyMode = "legacy" | "paginated"` to `Thread`. This will be stored in `SessionMeta` in the JSONL rollout file and as a new column in the SQLite thread_metadata table, and exposed on `thread/start` and on the `Thread` object in app-server. ## What changed - Added canonical `ThreadHistoryMode` with `legacy` and `paginated`, defaulting old and new SessionMeta to `legacy`. - Carried `history_mode` through core session config, ThreadStore stored metadata, local/in-memory stores, rollout metadata extraction, and the existing SQLite `threads` table. - Added experimental `historyMode` to app-server v2 `Thread` and `thread/start`. - Made paginated stored threads metadata-discoverable but unsupported for legacy full-history reads, `load_history`, live resume, and create paths. - Regenerated app-server schema fixtures and added protocol/state/thread-store/app-server coverage for persistence and fail-closed behavior. ## Compatibility floor Because users may be running various versions of Codex binaries on the same machine (TUI, Codex App, etc.), we will need to establish a compatibility floor for upcoming paginated threads, which will change how thread storage reads and writes work. The overall plan here: ``` Release N: - Add historyMode to SessionMeta / Thread / SQLite metadata. - Teach binaries to understand paginated threads. - If a binary sees `historyMode="paginated"` but does not support the paginated contract, it refuses to resume/mutate the thread. - Default remains `"legacy"`. Release N+1: - First-party clients start opting into paginated threads where appropriate. - Internal dogfood / staged rollout. - Measure old-client usage and paginated-thread unsupported errors. Release N+2: - Only after Release N+ is overwhelmingly deployed, make paginated the default. - Accept that a small tail of N-1-or-older binaries may not understand paginated threads. ``` The important behavior change is fail-closed handling for a binary that encounters a persisted `paginated` thread before it knows how to fully support paginated history. In app-server, if a thread is `paginated`, we will: - allow metadata-only discovery paths like `thread/list` and `thread/read(includeTurns=false)`, so clients can still see the thread and inspect its `historyMode` - reject legacy full-history/live-thread paths like `thread/read(includeTurns=true)` and `thread/resume` with an unsupported JSON-RPC error - avoid silently treating an unknown or future `historyMode` as `legacy` Under the hood, the ThreadStore layer also rejects legacy operations that would need to load or replay the full thread history for a paginated thread. That gives us the behavior we want for Release N: future paginated threads are visible, but this binary fails closed instead of trying to operate on them as if they were legacy threads. |

[codex] wire process-owned code mode host into core (#30142)
## Summary - add the `code_mode_host` feature flag and select `ProcessOwnedCodeModeSessionProvider` in `CodeModeService` when enabled - initialize code-mode sessions lazily so a missing host reports a tool error without failing thread startup - resolve `codex-code-mode-host` beside the running Codex binary by default while preserving `CODEX_CODE_MODE_HOST_PATH` as an override - add unit and end-to-end coverage for host resolution and graceful missing-host behavior ## Why This wires the process-owned session client from #30112 into the core service behind an opt-in rollout gate. Packaged Codex installations can place the helper in the same `bin` directory as the main executable without relying on `PATH`, while development and custom installations can continue to override the helper path. ## Stack - Depends on #30112 - Base branch: `cconger/process-owned-session-runtime-4-client` ## Validation Build `codex` and `codex-code-mode-host` `CODEX_CODE_MODE_HOST_PATH="$PWD/target/debug/codex-code-mode-host" ./target/debug/codex --enable code_mode_host` |

feat: add provider-aware model fallback to thread start (#29942)
## Why Helper threads such as task title generation can request a model ID that is valid for the default OpenAI provider but unavailable from the active provider. With Amazon Bedrock, `gpt-5.4-mini` is rejected while the provider static catalog exposes Bedrock model IDs such as `openai.gpt-5.5` and `openai.gpt-5.4`. This causes repeated background 404s and can surface a misleading turn error even when the main turn succeeds. Clients need an explicit way to ask app-server to resolve an unavailable helper model to the active provider default. That fallback must remain limited to providers with an authoritative static catalog so custom or dynamically discovered model IDs are not rewritten based on an incomplete catalog. Fixes #28741. ## What changed - Add the experimental `allowProviderModelFallback` option to `thread/start`, defaulting to `false` to preserve existing behavior. - Thread the option through thread creation and model selection. - When enabled for a static model manager, preserve requested models present in the catalog and replace unavailable models with the provider default. - Continue preserving explicit model IDs for dynamic model managers without fetching a catalog solely to validate them. - Document the new `thread/start` behavior in the app-server API overview. ## Test Temporary test-client harness: ``` ThreadStartParams { model: Some("gpt-5.4-mini".to_string()), allow_provider_model_fallback: true, ..Default::default() } ``` Command: ``` CODEX_HOME=/tmp/codex-bedrock-thread-start-home \ CODEX_E2E_BEDROCK_THREAD_START_ONLY=1 \ ./target/debug/codex-app-server-test-client \ --codex-bin ./target/debug/codex \ -c 'model_provider="amazon-bedrock"' \ send-message-v2 --experimental-api ignored ``` Relevant output: ``` > "method": "thread/start", > "params": { > "model": "gpt-5.4-mini", > "modelProvider": null, > "allowProviderModelFallback": true, > ... > } < "result": { < "model": "openai.gpt-5.5", < "modelProvider": "amazon-bedrock", < ... < } ``` |

core: make AGENTS.md react to environment changes (#29810)
## Why With deferred executors, a turn can begin before a remote environment attaches. AGENTS.md discovery previously ran only during session setup, so instructions from a later environment never reached the model or the session instruction sources. WorldState persistence has now landed, so this uses the durable model-visible baseline directly instead of carrying a temporary resume/fork compatibility path. ## What - Add an `AgentsMdManager` in `SessionServices` to own host instructions, loaded state, and refresh caching. - When `DeferredExecutor` is enabled, refresh AGENTS.md when attached environment selections change and freeze the result in the corresponding `StepContext`. - Represent AGENTS.md as a persisted WorldState section for every session, with bounded initial, replacement, and removal updates. - Remove duplicate AGENTS.md state and rendering from `SessionConfiguration` and `TurnContext`. - Build initial context, per-request updates, and compaction context from the same step-scoped value. - On resume and fork, compare current instructions with the restored WorldState baseline and inject a replacement exactly once when they differ. Builds on #29833, #29835, and #29837. ## Tests - Covers a remote environment becoming ready mid-turn, with AGENTS.md appearing on the next request exactly once and updating canonical instruction sources. - Covers full, unchanged, replaced, and removed AGENTS.md WorldState rendering. - Covers changed instructions across cold resume and fork without duplicate reinjection. - Covers remote-v2 compaction retaining creation-time instructions in the live session and cold resume appending one replacement when the source changed. - Ran focused `codex-core` AGENTS.md, WorldState, and context-update test suites. |

[codex] Add Ultra reasoning effort (#29899)
## Why Ultra should be one user-facing reasoning selection for work that benefits from both maximum reasoning and proactive multi-agent delegation. Without it, clients must coordinate maximum reasoning with the experimental `multiAgentMode` setting, even though the inference backend still expects its existing `max` effort value. This change makes reasoning effort the source of truth: clients select `ultra`, core derives proactive multi-agent behavior when the turn is eligible for multi-agent V2, and inference requests continue to use the backend-compatible `max` value. ## What changed - Add `ultra` as a first-class reasoning effort and preserve model-catalog ordering when exposing it to clients. - Convert `ultra` to `max` at the inference request boundary, including Responses HTTP/WebSocket requests, startup prewarm, compaction, and memory summarization. - Derive effective multi-agent mode per turn from effective reasoning effort: - eligible multi-agent V2 + `ultra` → `proactive` - eligible multi-agent V2 + any other effort → `explicitRequestOnly` - V1 or otherwise ineligible sessions → no multi-agent mode instruction - Keep the derived effective mode in turn context history so successive turns can emit a developer-message update only when the effective mode changes. - Remove selected multi-agent mode from core session configuration, turn construction, thread settings, resume/fork restoration, and subagent spawn plumbing. Subagents inherit reasoning effort and derive their own effective mode. - Retain the experimental app-server `multiAgentMode` fields for wire compatibility while marking them deprecated. Request values are accepted but ignored; compatibility response fields report `explicitRequestOnly`. - Display Ultra in the TUI using the order supplied by `model/list`. ## Validation - `just test -p codex-core ultra_reasoning_uses_max_for_requests` - `just test -p codex-tui model_reasoning_selection_popup` |

config: own layer provenance types (#29722)
## Why Config layer provenance describes how effective configuration was assembled, so it belongs with the config loader rather than in app-server's serialized API types. ## What changed - Moved `ConfigLayerSource`, `ConfigLayerMetadata`, and `ConfigLayer` ownership into `codex-config`. - Kept app-server's wire payloads unchanged and added explicit conversions at the app boundary. - Removed lower-level app-server-protocol dependencies from config consumers. ## Stack This is PR 3 of 6, stacked on [PR #29721](https://github.com/openai/codex/pull/29721). Review only the delta from `codex/split-auth-domain-types`. Next: [PR #29723](https://github.com/openai/codex/pull/29723). ## Validation - `codex-config` coverage passed. - App-server config-manager and config RPC coverage passed. |

Support thread-level originator overrides (#29477)
## Why Work(TPP) threads can be launched from the Desktop app, but if they all keep the Desktop app's default originator then downstream attribution cannot distinguish local Work launches from cloud-backed Work launches. `thread/start.serviceName` already carries that launch signal, while `SessionMeta.originator` is the durable thread-level value that survives resume and fork. This change converts the Desktop Work service names into an effective originator at thread creation time, persists that originator with the thread, and keeps using it for later model requests and memory writes. ## What changed - Map `CODEX_WORK_LOCAL` and `CODEX_WORK_CLOUD` service names to per-thread originators, while preserving `CODEX_INTERNAL_ORIGINATOR_OVERRIDE` as the highest-precedence override. - Persist the effective originator in `SessionMeta.originator`, read it back on resume/fork, and inherit the parent originator for subagent spawns when there is no persisted session metadata. - Handle truncated `SpawnAgentForkMode::LastNTurns` forks by falling back to the live parent originator when the forked history no longer includes `SessionMeta`. - Thread the per-thread originator through Responses headers, websocket/compaction request paths, thread-store creation, rollout metadata, and memory stage-one telemetry. ## Verification - `just test -p codex-core agent::control::tests::spawn_thread_subagent_inherits_parent_originator_without_fork agent::control::tests::spawn_thread_subagent_fork_last_n_turns_inherits_parent_originator_without_session_meta thread_manager::tests::originator_override_precedes_service_name_remapping` - `just test -p codex-core agent::control::tests::resume_thread_subagent_restores_stored_metadata_and_effective_multi_agent_mode` - `just test -p codex-memories-write` - `just fix -p codex-core -p codex-memories-write` - `git diff --check` |

core: use current step environments for tools (#29547)
## Why With deferred executors, an environment can become ready between two sampling requests in the same turn. The model-visible environment update, advertised tools, and eventual tool execution must all describe the same request-time view. Otherwise, a request built while only environment B is ready can advertise a tool without an `environment_id`; if higher-priority environment A becomes ready before execution, that call could silently run in A instead. This PR is stacked on #29527. ## Design `run_turn` captures one `Arc<StepContext>` at each sampling-request boundary. That step owns the request's `TurnContext` and environment snapshot. - World-state environment updates and tool planning borrow that same step. - `ToolCallRuntime` retains the `Arc` while asynchronous tool calls execute. - `ToolInvocation` carries the step to handlers; its temporary `turn` compatibility field is derived from the same object. - `ToolRouter` does not retain `StepContext`; it only uses it while constructing the request's tool set. - With `DeferredExecutor` disabled, step capture keeps using the environments frozen at turn start. Simply: every sampling request gets one consistent picture of its environments, from what the model sees through where its tool calls run. ## What changed - Build environment-dependent tool specs from the current request's `StepContext`. - Use that same step for unified exec, legacy shell, `apply_patch`, `view_image`, and `request_permissions` execution. - Hide environment-backed tools, including `request_permissions`, while no environment is attached. - Resolve legacy shell paths and metadata from the selected step environment instead of the stale turn-start environment. - Capture explicit steps at non-turn-loop boundaries such as compaction, prompt debug, and startup prewarm. - Reconcile prompt-debug history from the same step used to build its tools. ## Follow-up - Bind yielded code-mode cells to the tool runtime that created them, so nested calls made after yielding continue to use the originating request's `StepContext`. ## Test plan - `just test -p codex-core deferred_executor_updates_context_and_tools_after_startup` - `just test -p codex-core environment_count_controls_environment_backed_tools` - `just test -p codex-core build_prompt_input_includes_context_and_user_message` |

core: use turn-owned world state for inline compaction (#29527)
## Why Follow-up to #29249 and its [compaction review thread](https://github.com/openai/codex/pull/29249#discussion_r3455055101). During a turn, environment readiness can change between sampling requests. Inline compaction must render the same model-visible `WorldState` used by the request it follows. Rebuilding that state during compaction can observe a newer environment, make replacement history disagree with what the model saw, and suppress the next environment update. ## What changed - Make `run_turn` own the current `Arc<WorldState>` and replace it only between sampling requests. - Build each state from an explicitly chosen environment snapshot, diff deferred-executor steps against the turn-owned state, and retain the latest state in `ContextManager` only for cross-turn and resume tracking. - Pass the exact turn-owned state into inline compaction and explicit new-context-window replacement. - Carry that state with `InitialContextInjection::BeforeLastUserMessage`, so replacement context and its stored baseline cannot come from different snapshots. - Remove obsolete state-recapture helpers and ambiguous TurnContext-only WorldState builders. - Add an integration test that moves an environment from starting to ready during a paused turn, triggers compaction, and verifies the next request receives the readiness update exactly once. ## Test plan - `just test -p codex-core deferred_executor_compaction_preserves_then_updates_environment_once` - `just test -p codex-core process_compacted_history` - `just test -p codex-core mid_turn_continuation_compaction` - `just test -p codex-core build_initial_context` - `just test -p codex-core ignores_session_prefix_messages_when_truncating` |

core: rename metadata -> internal_chat_message_metadata_passthrough (#28968)
## Description This PR cuts Codex over from generic `ResponseItem.metadata` (introduced here: https://github.com/openai/codex/pull/28355) to `ResponseItem.internal_chat_message_metadata_passthrough`, which is the blessed path and has strongly-typed keys. For now we have to drop this MAv2 usage of `metadata`: https://github.com/openai/codex/pull/28561 until we figure out where that should live. |

Expose thread-level multi-agent mode (#28792)
## Why Once multi-agent mode can be selected per turn, clients also need to choose the initial selection when creating a thread and observe that selection through lifecycle and settings APIs. The selected value is intentionally distinct from the effective model-visible value: no client selection is represented as `null`, even though an eligible multi-agent v2 turn derives `explicitRequestOnly` as its effective default. ## What changed - Add the optional experimental `thread/start.multiAgentMode` parameter and pass it through thread creation. - Preserve an omitted initial value as an unset selection rather than eagerly storing `explicitRequestOnly`. - Apply an explicit `thread/start` selection to the first turn through the session configuration established at thread creation. - Restore the latest persisted effective mode as the selected baseline on cold resume when rollout history contains one. - Inherit the optional selected mode from a loaded parent when creating related runtime threads. - Return the current selected `multiAgentMode` from `thread/start`, `thread/resume`, `thread/fork`, and thread settings, using `null` when no mode is selected. - Keep lifecycle reporting independent from model capability and feature eligibility; core turn construction remains responsible for calculating and persisting the effective mode. ## Not covered - Clearing an existing loaded-session selection back to unset through `turn/start`; omitted or `null` currently retains the session's selection. - A TUI control, slash command, or `config.toml` preference. ## Verification - `CARGO_INCREMENTAL=0 just test -p codex-app-server-protocol` - `CARGO_INCREMENTAL=0 just test -p codex-app-server multi_agent_mode` The focused app-server coverage verifies explicit `thread/start` initialization, first-turn prompting, nullable reporting for an omitted selection, and retention of selections that are not currently runtime-eligible. ## Stack Stacked on #28685. This PR contains only the thread initialization and lifecycle/settings API layer. |

Replace SkillsManager with SkillsService (#28705)
## Why Host skill discovery was still exposed as a manager even though it is a process-owned service shared by sessions, the app-server catalog, and file-watcher invalidation. The skills extension also consumed an ad hoc loaded-skills wrapper instead of a named immutable snapshot. ## What changed - replace `SkillsManager` with concrete `SkillsService` - make the service cache and return immutable `HostSkillsSnapshot` values - migrate the skills extension host provider to the snapshot boundary - migrate app-server catalog, watcher, and invalidation paths to the service This keeps the service limited to host discovery, caching, roots, and invalidation. Catalog rendering and invocation remain extension responsibilities for the next stacked change. |

core: remove redundant TurnContext and Prompt fields (#28638)
## Why `TurnContext` had accumulated dead fields and cached projections of values already owned by its per-turn `Config` or `ModelInfo`. Keeping both copies made ownership unclear and allowed artificial split-brain states, such as a compatibility hash differing from the model metadata it came from. `Prompt` similarly carried a write-only personality after personality selection had already been materialized into its base instructions. This makes the canonical owner explicit: configuration-backed values come from `config`, model-derived values come from `model_info`, and prompts contain only data consumed by request construction. ## What changed - Remove the unused `ghost_snapshot`, `codex_self_exe`, and `thread_source` fields. - Remove duplicate `comp_hash`, `truncation_policy`, `features`, `shell_environment_policy`, `codex_linux_sandbox_exe`, `compact_prompt`, and `tool_mode` fields. - Read those values directly from `TurnContext::config` or `TurnContext::model_info` at their consumers. - Remove the write-only `Prompt::personality` field and its constructor assignments. - Preserve review-turn inheritance of the parent turn's shell policy, Linux sandbox executable, and compact prompt through the review config. ## Testing - `cargo check -p codex-core --tests` |

[codex] Bind shell snapshots to retained thread environments (#28421)
## Why Shell snapshots are currently session-scoped even though shell and cwd are properties of a selected turn environment. That makes snapshot refresh depend on separate session-cwd plumbing, prevents retained environments from retaining their snapshot work, and can make snapshot construction use a different shell than command execution. This follows #27955 by making the retained thread-environment service own environment snapshot lifecycles. Session configuration remains the requested selection state, while `ThreadEnvironments` remains the source of successfully resolved environments. ## What changed - Configure the shell-snapshot builder before initial environment resolution. - Start each local environment snapshot task when its `TurnEnvironment` is built and retain that shared task while environment ID and cwd still match. - Inherit retained environment snapshots into spawned child threads. - Carry the selected `TurnEnvironment` through shell runtimes so snapshot construction and command execution use the same environment-specific shell and cwd. - Load project instructions and warm plugins/skills after initial environment resolution. - Continue decoding invalid UTF-8 instruction files lossily without emitting a startup warning. - Keep requested selections in `SessionConfiguration`; failed or duplicate resolutions only affect the resolved environment snapshot. ## Validation - `cargo check -p codex-core --tests` - `just test -p codex-home instructions` (6 passed) - Focused environment, instruction, shell-snapshot, and user-shell tests (84 passed) - Focused shell-snapshot, user-shell, and unified-exec tests (126 passed; two event-timing tests passed on retry) |

[codex] retain resolved environments across turns (#27955)
## Why Selected execution environments are thread-scoped resources, but startup and turn construction repeatedly resolved their IDs and working directories. That discarded existing environment handles and shell metadata even when a selection had not changed. Session configuration updates also need to affect future turns without changing the resolved environment set already captured by a running turn. ## What changed - Create a `ThreadEnvironments` service inside `Codex` from the spawned `EnvironmentManager` and raw environment selections, then store it on `SessionServices`. - Split service construction from `update_selections`, allowing session configuration updates to mutate the resolved set in place. - Retain an existing `TurnEnvironment` when its environment ID and working directory match; resolve only added or changed selections and remove selections that are no longer present. - Normalize duplicate IDs by keeping the first selection and skip individual selections that fail to resolve instead of rejecting the entire update. - Give each `TurnContext` a cloned `TurnEnvironmentSnapshot`, so later session configuration updates affect future turns without rewriting an active turn. - Reuse the service-owned environment manager and resolved snapshot for startup work, MCP initialization, and child-thread spawning instead of flowing resolved environments through spawn arguments. ## Test plan - `cargo check -p codex-core --tests` - `just test -p codex-core environment_selection` - `just test -p codex-core turn_environments` - `just test -p codex-core session_update_settings_does_not_rewrite_sticky_environment_cwds` - `just test -p codex-core default_turn_does_not_overlay_legacy_fallback_cwd_onto_stored_thread_environments` |

feat(core): add metadata field to ResponseItem (#28355)
## Description This PR adds an optional `metadata` field to `ResponseItem` for Responses API calls. Only mechanical plumbing, no actual values populated and sent yet. Turns out just adding a new field to `ResponseItem` has quite a large blast radius already. This change is backwards compatible because `metadata` is optional and omitted when absent, so existing response items and rollout history without it still deserialize and requests that do not set it keep the same wire shape. For provider compatibility, we strip out `metadata` before non-OpenAI Responses requests so Azure and AWS Bedrock never see this field. My followup PR here will actually make use of it to start storing and passing along `turn_id`: https://github.com/openai/codex/pull/28360 ## What changed - Added `ResponseItemMetadata` with optional `turn_id`, plus optional `metadata` on Responses API item variants and inter-agent communication. - Preserved item metadata through response-item rewrites such as truncation, missing tool-output synthesis, compaction history rebuilding, visible-history conversion, rollout/resume, and generated app-server schemas/types. - Strip item metadata from non-OpenAI Responses requests while preserving it for OpenAI-shaped requests. - Updated the mechanical fixture/test construction churn required by the new optional field. |

[codex] Load user instructions through an injected provider (#27101)
## Why We want to remove implicit use of `$CODEX_HOME` from `codex-core` and make embedders responsible for supplying user-level instructions. This also ensures user instructions load when no primary environment is selected. ## What changed Stacked on #27415, which makes `codex exec` surface thread-scoped runtime warnings. - Added `UserInstructionsProvider` to `codex-extension-api`, with absolute source attribution and recoverable loading warnings. - Added `codex-home` with the filesystem-backed provider for `AGENTS.override.md` and `AGENTS.md`, preserving precedence, fallback, trimming, lossy UTF-8 handling, and the existing uncapped global instruction size. - Removed global instruction loading from `Config` and require `ThreadManager` callers to inject a provider. - Load provider instructions once for each fresh root runtime, including runtimes without a primary environment. Running sessions retain their snapshot, while child agents inherit the parent snapshot without invoking the provider. - Keep provider instructions separate while loading project `AGENTS.md`, then assemble the model-visible instructions with the existing ordering, source attribution, warning, and turn-context behavior. - Wired the Codex home provider through the CLI, app server, MCP server, core facade, and thread-manager sample. ## Validation - `just test -p codex-home -p codex-extension-api` - `just test -p codex-core agents_md` - `just test -p codex-core guardian` - `just test -p codex-app-server thread_start_without_selected_environment_includes_only_global_instruction_source` - `just test -p codex-exec warning` - `just bazel-lock-check` |

Load selected executor skills through extensions (#27184)
## Why
CCA is moving toward a split runtime where the orchestrator may not have
a filesystem, while executors can expose preinstalled plugins and
skills. A thread therefore needs to select capabilities without asking
app-server or core to interpret executor-owned paths through the
orchestrator's filesystem.
The longer-term model is broader than executor skills:
- A plugin is a bundle of skills, MCP servers, connectors/apps, and
hooks.
- A plugin root can be local, executor-owned, or hosted by a backend.
- Components inside one plugin can use different access and execution
mechanisms. A skill may be read from a filesystem or through backend
tools; an HTTP MCP server can run without an executor; a stdio MCP
server or hook needs an execution environment.
- Core should carry generic extension initialization data. The extension
that owns a component should discover it, expose it to the model, and
invoke it through the appropriate runtime.
This PR establishes that architecture through one complete vertical:
selecting a root on an executor, discovering the skills beneath it,
exposing those skills to the model, and reading an explicitly invoked
`SKILL.md` through the same executor.
## Contract
`thread/start` gains an experimental `selectedCapabilityRoots` field:
```json
{
"selectedCapabilityRoots": [
{
"id": "deploy-plugin@1",
"location": {
"type": "environment",
"environmentId": "workspace",
"path": "/opt/codex/plugins/deploy"
}
}
]
}
```
The root is intentionally not classified as a "plugin" or "skill" in the
API. It can point at a standalone skill, a directory containing several
skills, or a plugin containing skills and other components. This PR only
teaches the skills extension how to consume it; later extensions can
resolve MCP, connector, and hook components from the same selection.
The platform-supplied `id` is stable selection identity. The location
says which runtime owns the root and gives that runtime an opaque path.
App-server does not inspect or canonicalize the path.
## What changed
### Generic thread extension initialization
App-server converts selected roots into `ExtensionDataInit`. Core
carries that generic initialization value until the final thread ID is
known, then creates thread-scoped `ExtensionData` before lifecycle
contributors run.
This keeps `Session` and core independent of the capability-selection
contract. The initialization value is consumed during construction; it
is not retained as another long-lived `Session` field.
### Executor-backed skills
The skills extension now owns an `ExecutorSkillProvider` that:
- resolves the selected environment through `EnvironmentManager`
- discovers, canonicalizes, and reads skills through that environment's
`ExecutorFileSystem`
- contributes the bounded selected-skill catalog as stable developer
context
- reads an explicitly invoked skill body through the authority that
listed it
- warns when an environment or root is unavailable
- never falls back to the orchestrator filesystem for an executor-owned
root
Skill catalog and instruction fragments have hard byte bounds, which
also bound them below the 10K-token per-item context limit. If a
selected executor skill has the same name as a legacy local skill, the
executor selection owns that invocation and the local body is not
injected a second time.
Existing local and bundled skill loading remains in place. Omitting
`selectedCapabilityRoots` therefore preserves current local-only
behavior.
## Current semantics
- Only environment-owned locations are represented in this first
contract.
- Roots are resolved by the destination extension, not by app-server or
core.
- An unavailable executor or invalid root produces a warning and no
capabilities from that root; it does not trigger a local-filesystem
fallback.
- Selection applies to a newly started active thread.
- MCP servers, connectors, and hooks beneath a selected plugin root are
not activated yet.
- Selection is not yet persisted or inherited across resume, fork, or
subagent creation. Existing local capabilities continue to behave as
they do today in those flows.
## Planned vertical follow-ups
1. **Hosted HTTP MCP:** add an extension-backed HTTP MCP source that
works without an executor, then replace the special-purpose MCP plugins
loader with that implementation.
2. **Executor MCP:** register and execute stdio MCP servers through the
environment that owns the selected plugin root.
3. **Backend skills:** add a hosted skill source whose catalog and
bodies are accessed through extension tools rather than a filesystem.
4. **Connectors and hooks:** activate those components through their
owning extensions, using the same selected-root boundary and
component-specific runtime.
5. **Durable selection:** define the desired-selection lifecycle,
persist it, and make resume, fork, and subagent inheritance explicit
rather than accidental.
6. **Local convergence:** incrementally route existing local plugin,
skill, and MCP loading through the same extension model while preserving
current local behavior.
Each follow-up remains reviewable as an end-to-end capability. The
platform selects roots, generic thread extension data carries the
selection, and the owning extension resolves and operates its component.
## Verification
Coverage added for:
- app-server end-to-end discovery and explicit invocation of a skill
inside an executor-selected plugin root
- exclusive invocation when a selected executor skill collides with a
local skill name
- executor filesystem authority for discovery, canonicalization, and
reads
- thread extension initialization before lifecycle contributors run
- stable executor catalog context, explicit invocation, context
rebuilding, hidden skills, and preserved host/remote catalog behavior
Targeted protocol, core-skills, skills-extension, core lifecycle, and
app-server executor-skill tests were run during development.

Add environmentId to request_permissions (#25858)
## Stack 1. #25850 - Key request-permission grants by environment: stores and applies sticky permission grants per environment id. 2. This PR (#25858) - Add `environmentId` to `request_permissions`: lets the model target a selected environment and resolves relative permission paths against it. 3. #25862 - Propagate permission approval environment id: carries the selected environment id through approval events, app-server requests, TUI prompts, and delegate forwarding. 4. #25867 - Add remote request permissions integration coverage: verifies the selected remote environment across request, approval, grant reuse, and exec. This PR is stacked on #25850; #25862 and #25867 are stacked on this PR. ## Why PR1 made request-permission grants internally environment-keyed, but the model-facing `request_permissions` tool could still only target the primary environment. For CCA and multi-environment turns, the tool needs an explicit way to bind a permission request to a selected attached environment before resolving relative paths. ## What Changed - Added optional `environmentId` to `RequestPermissionsArgs`, with `environment_id` accepted as an alias. - Exposed `environmentId` in the `request_permissions` tool schema and description. - Resolve the selected environment before parsing filesystem permission paths, so relative paths bind to the selected environment cwd. - Route validated tool calls through `request_permissions_for_environment` directly instead of duplicating environment lookup in `Session::request_permissions`. - Reject unknown environment ids with a model-facing error. - Updated focused request-permissions and Guardian call sites for the new optional field. ## Testing Not run locally per instruction. |

Key request-permission grants by environment (#25850)
## Stack 1. This PR (#25850) - Key request-permission grants by environment: stores and applies sticky permission grants per environment id. 2. #25858 - Add `environmentId` to `request_permissions`: lets the model target a selected environment and resolves relative permission paths against it. 3. #25862 - Propagate permission approval environment id: carries the selected environment id through approval events, app-server requests, TUI prompts, and delegate forwarding. 4. #25867 - Add remote request permissions integration coverage: verifies the selected remote environment across request, approval, grant reuse, and exec. #25858, #25862, and #25867 are stacked on this PR and should be reviewed after it. ## Why Multi-environment CCA turns can attach both local and remote executors, but request-permission grants were still effectively cwd-only. Pending permission requests tracked a cwd, while stored turn/session grants had no environment identity, so sticky grants could be reused through the wrong executor context. This makes the first permission-grant step environment-aware without changing the external `request_permissions` payload shape: omitted environment targeting remains bound to the primary turn environment. ## What Changed - Store turn- and session-scoped request-permission grants by `environment_id`. - Keep the selected `TurnEnvironmentSelection` with pending `request_permissions` calls so approval responses normalize and record grants against the same environment. - Resolve relative `request_permissions` file paths against the primary turn environment cwd instead of deprecated `turn.cwd`. - Apply sticky grants in `shell`, `exec_command`, and `apply_patch` by selected environment id while still using the actual tool cwd for cwd-relative permission materialization. - Update Guardian and request-permissions coverage for the environment-keyed grant behavior. ## Testing Not run locally. Added or updated focused coverage for: - `request_permission_grants_are_environment_keyed` - `request_permissions_tool_resolves_relative_paths_against_primary_environment` - related Guardian/request-permissions sticky grant tests |

app-server: remove experimental persist_extended_history bool flag (#25712)
## Summary Remove the dead experimental `persistExtendedHistory` app-server flag and collapse rollout persistence to the single policy app-server already used. ## What Changed - Removed `persistExtendedHistory` from v2 thread start/resume/fork params and deleted its deprecation notice path. - Removed the persistence-mode enums and plumbing through core, rollout, and thread-store. - Made rollout filtering mode-free, keeping the existing limited persisted-history behavior. ## Test Plan - `just write-app-server-schema` - `cargo nextest run --no-fail-fast -p codex-app-server-protocol schema_fixtures` - `cargo nextest run --no-fail-fast -p codex-app-server thread_shell_command_history_responses_exclude_persisted_command_executions` - `cargo nextest run --no-fail-fast -p codex-rollout -p codex-thread-store` - final `rg` for removed flag/type names |

store and expose parent_thread_id on Threads (#25113)
## Why This PR https://github.com/openai/codex/pull/24161#discussion_r3325692763 revealed a subagent data modeling issue, where we overloaded `forked_from_id` to also mean `parent_thread_id`. That's incorrect since guardian and review subagents can be a subagent and NOT fork the main thread's history. The solution here is to explicitly store a new `parent_thread_id` on `SessionMeta`, alongside `forked_from_id` which already exists. While we're at it, also expose it in the app-server protocol on the `Thread` object. A thread->subagent relationship and a fork of thread history are orthogonal concepts. ## What Changed - Added top-level `parent_thread_id` persistence on `SessionMeta` and runtime/session plumbing through `SessionConfiguredEvent`, `CodexSpawnArgs`, `SessionConfiguration`, `ThreadConfigSnapshot`, `TurnContext`, and `ModelClient`. - Made turn metadata, request headers, analytics, and subagent-start events read the separate runtime/top-level parent field instead of deriving general parent lineage from `SessionSource` or `forked_from_thread_id`. - Passed parent lineage separately at delegated subagent, review, guardian, agent-job, and multi-agent spawn construction sites; copied-history fork lineage remains derived only from `InitialHistory`. - Persisted and exposed parent lineage through rollout/thread-store projections and app-server v2 `Thread.parentThreadId`. - Updated app-server README text and regenerated app-server schema fixtures for the additive `parentThreadId` response field. |

Add forked_from_thread_id turn metadata (#24160)
## Why When Codex calls responsesapi, we currently send `session_id`, `thread_id`, and `turn_id` among other things as `client_metadata["x-codex-turn-metadata"]`. This PR adds `forked_from_thread_id` which helps explain the "lineage" of a forked thread. ## What's changed - Track the immediate history source copied into a forked thread through thread/session creation, including subagent and review turn metadata paths. - Include `forked_from_thread_id` in Codex turn metadata while preventing turn-scoped Responses API client metadata from overwriting Codex-owned lineage fields. - Add coverage for fork lineage in turn metadata and the app-server Responses API request path. |

Simplify tool executor and registry plumbing (#22636)
## Why The tool runtime path still had a typed output associated type on `ToolExecutor`, plus a core-only `RegisteredTool` adapter and extension-only executor aliases. That made every new shared tool runtime carry extra adapter plumbing before it could participate in core dispatch, extension tools, hook payloads, telemetry, and model-visible spec generation. This PR moves output erasure to the shared executor boundary so core and extension tools can use the same execution contract directly. ## What Changed - Changed `codex_tools::ToolExecutor` to return `Box<dyn ToolOutput>` instead of an associated `Output` type. - Removed the extension-specific `ExtensionToolExecutor` / `ExtensionToolOutput` aliases and exposed `ToolExecutor<ToolCall>` plus `ToolOutput` through `codex-extension-api`. - Reworked core tool registration around `CoreToolRuntime` and `ToolRegistry::from_tools`, removing the extra `RegisteredTool` / `ToolRegistryBuilder` layer. - Consolidated model-visible spec planning and registry construction in `core/src/tools/spec_plan.rs`, including deferred tool search and code-mode-only filtering. - Added `ToolOutput` helpers for post-tool-use hook ids and inputs so MCP, unified exec, extension, and other boxed outputs preserve the same hook payload behavior. - Updated core handlers, memories tools, and the related registry/spec/router tests to use the simplified contract. ## Test Coverage - Updated coverage for tool spec planning, registry lookup, deferred tool search registration, extension tool routing, post-tool-use hook payloads, dispatch tracing, guardian output extraction, and memories extension tool execution. |

Deprecate TurnContext cwd and resolve_path (#22519)
## Why `TurnContext::cwd` and `TurnContext::resolve_path` are being phased out in favor of using the selected turn environment cwd directly. Deprecating both APIs makes any new direct dependency visible while preserving the existing migration path for current callers. ## What Changed - Marked `TurnContext::cwd` and `TurnContext::resolve_path` as deprecated with guidance to use the selected turn environment cwd instead. - Added exact `#[allow(deprecated)]` suppressions at each existing direct usage site, including tests, rather than adding crate-wide suppression. - Kept the change behavior-preserving: current cwd reads, writes, and path resolution continue to use the same values. ## Verification - `just fmt` - `cargo check -p codex-core` - `cargo check -p codex-core --tests` - `git diff --check` |

[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` - `cargo test -p codex-core tools::router` - `cargo test -p codex-core active_call_preserves_triggering_command_context` - `cargo test -p codex-core guardian_tests` - `cargo test -p codex-core --test all shell_serialization` - `cargo test -p codex-core --test all apply_patch_cli` - `cargo test -p codex-core --test all shell_command_` - `cargo test -p codex-core --test all local_shell` - `cargo test -p codex-core --test all otel::` - `cargo test -p codex-core --test all hooks::` - `just fix -p codex-core` - `just fix -p codex-tools` |

extension: wire extension registries into sessions (#21737)
## Why [#21736](https://github.com/openai/codex/pull/21736) introduces the typed extension API, but the runtime does not yet carry a registry through thread/session startup or give contributors host-owned stores to read from. This PR wires that host-side path so later feature migrations can move product-specific behavior behind typed contributions without adding another bespoke seam directly to `codex-core`. ## What changed - Thread `ExtensionRegistry<Config>` through `ThreadManager`, `CodexSpawnArgs`, `Session`, and sub-agent spawn paths. - Wire `ThreadStartContributor` and `ContextContributor` - Expose the small supporting surface needed by non-core callers that construct threads directly, including `empty_extension_registry()` through `codex-core-api`. This PR lands the host plumbing only: the app-server registry is still empty, and concrete feature migrations are intended to follow separately. |

[codex] request desktop attestation from app (#20619)
## Summary TL;DR: teaches `codex-rs` / app-server to request a desktop-provided attestation token and attach it as `x-oai-attestation` on the scoped ChatGPT Codex request paths.  ## Details This PR teaches the Codex app-server runtime how to request and attach an attestation token. It does not generate DeviceCheck tokens directly; instead, it relies on the connected desktop app to advertise that it can generate attestation and then asks that app for a fresh header value when needed. The flow is: 1. The Codex desktop app connects to app-server. 2. During `initialize`, the app can advertise that it supports `requestAttestation`. 3. Before app-server calls selected ChatGPT Codex endpoints, it sends the internal server request `attestation/generate` to the app. 4. app-server receives a pre-encoded header value back. 5. app-server forwards that value as `x-oai-attestation` on the scoped outbound requests. The code in this repo is mostly protocol and runtime plumbing: it adds the app-server request/response shape, introduces an attestation provider in core, wires that provider into Responses / compaction / realtime setup paths, and covers the intended scoping with tests. The signed macOS DeviceCheck generation remains owned by the desktop app PR. ## Related PR - Codex desktop app implementation: https://github.com/openai/openai/pull/878649 ## Validation <details> <summary>Tests run</summary> ```sh cargo test -p codex-app-server-protocol cargo test -p codex-core attestation --lib cargo test -p codex-app-server --lib attestation ``` Also ran: ```sh just fix -p codex-core just fix -p codex-app-server just fix -p codex-app-server-protocol just fmt just write-app-server-schema ``` </details> <details> <summary>E2E DeviceCheck validation</summary> First validated the signed desktop app boundary directly: launched a packaged signed `Codex.app`, sent `attestation/generate`, decoded the returned `v1.` attestation header, and validated the extracted DeviceCheck token with `personal/jm/verify_devicecheck_token.py` using bundle ID `com.openai.codex`. Apple returned `status_code: 200` and `is_ok: true`. Then ran the fuller app + app-server flow. The packaged `Codex.app` launched a current-branch app-server via `CODEX_CLI_PATH`, and a local MITM proxy intercepted outbound `chatgpt.com` traffic. The app-server requested `attestation/generate` from the real Electron app process, and the intercepted `/backend-api/codex/responses` traffic included `x-oai-attestation` on both routes: ```text GET /backend-api/codex/responses Upgrade: websocket x-oai-attestation: present POST /backend-api/codex/responses Upgrade: none x-oai-attestation: present ``` The captured header decoded to a DeviceCheck token that also validated with Apple for `com.openai.codex` (`status_code: 200`, `is_ok: true`, team `2DC432GLL2`). </details> --------- Co-authored-by: Codex <noreply@openai.com> |

[codex] Move tool specs onto handlers (#21461)
## Why This is the next stacked step after deleting the tool-handler kind indirection. Specs should come from the registered handlers themselves so registry construction has a single source of truth for handler behavior and exposed tool definitions. ## What changed - Added `ToolHandler::spec()` plus handler-provided parallel/code-mode metadata, and made `ToolRegistryBuilder::register_handler` automatically collect specs from registered handlers. - Moved builtin tool spec construction into the corresponding handlers and their adjacent `_spec` modules, including shell, unified exec, apply patch, view image, request plugin install, tool search, MCP resource, goals, planning, permissions, agent jobs, and multi-agent tools. - Reworked configurable handlers to receive their tool-building options through constructors, with non-optional handler options where the handler is always spec-backed. Shell fallback handlers keep an explicit no-spec mode because they are also registered as hidden dispatch aliases. - Kept `CodeModeExecuteHandler` on the explicit configured wrapper so the code-mode exec spec can still be built from the nested registry. ## Verification - `cargo check -p codex-core` - `cargo test -p codex-core tools::spec_plan::tests` - `cargo test -p codex-core tools::spec::tests` - `cargo test -p codex-core tools::handlers::multi_agents_spec::tests` - `RUST_MIN_STACK=16777216 cargo test -p codex-core tools::handlers::multi_agents::tests` - `cargo test -p codex-core tools::handlers::apply_patch::tests` - `cargo test -p codex-core tools::handlers::unified_exec::tests` - `just fix -p codex-core` - `git diff --check` |

Revert state DB injection and agent graph store (#21481)
## Why Reverts #20689 to restore the previous optional state DB plumbing. The conflict resolution keeps the newer installation ID and session/thread identity changes that landed after #20689, while removing the mandatory state DB and agent graph store dependency from ThreadManager construction. ## What changed - Restored `Option<StateDbHandle>` through app-server, MCP server, prompt debug, and test entry points. - Removed the `codex-core` dependency on `codex-agent-graph-store` and reverted descendant lookup back to the existing state DB path when available. - Kept newer `installation_id` forwarding by passing it beside the optional DB handle. - Kept local thread-name updates working when the optional state DB handle is absent. ## Validation - `git diff --check` - `cargo test -p codex-thread-store` - `cargo test -p codex-state -p codex-rollout -p codex-app-server-protocol` - Attempted `env CARGO_INCREMENTAL=0 cargo test -p codex-core -p codex-app-server -p codex-app-server-client -p codex-mcp-server -p codex-thread-manager-sample -p codex-tui`; blocked locally by a rustc ICE while compiling `v8 v146.4.0` with `rustc 1.93.0 (254b59607 2026-01-19)` on `aarch64-apple-darwin`. |

Move skills watcher to app-server (#21287)
## Why Skills update notifications are app-server API behavior, but the watcher lived in `codex-core` and surfaced through `EventMsg::SkillsUpdateAvailable`. Moving the watcher out keeps core focused on thread execution and lets app-server own both cache invalidation and the `skills/changed` notification. ## What changed - Added an app-server-owned skills watcher that watches local skill roots, clears the shared skills cache, and emits `skills/changed` directly. - Registers skill watches from the common app-server thread listener attach path, including direct starts, resumes, and app-server-observed child or forked threads. - Stores the `WatchRegistration` on `ThreadState`, so listener replacement, thread teardown, idle unload, and app-server shutdown deregister by dropping the RAII guard. - Removed `EventMsg::SkillsUpdateAvailable`, the core watcher, and the old core live-reload test. - Extended the app-server skills change test to verify a cached skills list is refreshed after a filesystem change without forcing reload. ## Validation - `cargo check -p codex-core -p codex-app-server -p codex-mcp-server -p codex-rollout -p codex-rollout-trace` - `cargo test -p codex-app-server skills_changed_notification_is_emitted_after_skill_change` |

Move installation ID resolution out of core startup (#21182)
## Summary - resolve or inject the installation ID before core startup and pass it through `ThreadManager`, `CodexSpawnArgs`, and `Session` as a plain `String` - keep child sessions on the parent installation ID instead of rediscovering it inside core - propagate installation ID startup failures in `mcp-server` instead of panicking ## Why Core was still touching the filesystem on the session startup path to discover `installation_id`. This moves that work to the outer host boundary so core no longer depends on `codex_home` reads during session construction. --------- Co-authored-by: Codex <noreply@openai.com> |

[codex-analytics] rework thread_source for thread analytics (#20949)
## Summary - make `thread_source` an explicit optional thread-level field on `thread/start`, `thread/fork`, and returned thread payloads - persist `thread_source` in rollout/session metadata so resumed live threads retain the original value - replace the old best-effort `session_source` -> `thread_source` mapping with an explicit caller-supplied analytics classification ## Why Before this change, analytics `thread_source` was populated by a best-effort mapping from `session_source`. `session_source` describes the runtime/client surface, not the actual thread-level origin, so that projection was not accurate enough to distinguish cases such as `user`, `subagent`, `memory_consolidation`, and future thread origins reliably. Making `thread_source` explicit keeps one thread-level analytics field while letting callers provide the real classification directly instead of recovering it indirectly from `session_source`. ## Impact For new analytics events, `thread_source` now reflects the explicit thread-level classification supplied by the caller rather than an inferred value derived from `session_source`. Existing protocol fields remain optional; callers that omit `threadSource` now produce `null` instead of a best-effort inferred value. ## Validation - `just write-app-server-schema` - `cargo test -p codex-analytics -p codex-core -p codex-app-server-protocol --no-run` - `cargo test -p codex-app-server-protocol generated_ts_optional_nullable_fields_only_in_params` - `cargo test -p codex-analytics thread_initialized_event_serializes_expected_shape` - `cargo test -p codex-core resume_stopped_thread_from_rollout_preserves_thread_source` |

Inject state DB, agent graph store (#20689)
## Why We want the agent graph store to be passed down the stack as a real dependency, the same way we already treat the thread store. This will let us inject the agent graph store as a real dependency and support implementations other than the local SQLite-backed one. Right now most code instantiates a state DB and an agent graph store just-in-time. Ideally, we would not depend on the state DB directly but only read through the higher-level interfaces. This change makes the dependency boundaries explicit and moves state DB initialization to process bootstrap instead of hiding it inside local store implementations. ## What changed - `ThreadManager` now requires a `StateDbHandle` and an `AgentGraphStore` at construction time instead of treating them as optional internals. - The local store constructors no longer lazily initialize SQLite. Callers now initialize the state DB once per process and use that shared handle to build: - `LocalThreadStore` - `LocalAgentGraphStore` - App bootstraps (`app-server`, `mcp-server`, `prompt_debug`, and the thread-manager sample) now initialize the state DB up front and inject the resulting handle down the stack. - `app-server` now consistently uses its process-scoped state DB handle instead of reopening SQLite or trying to recover it from loaded threads. - Device-key storage now reuses the shared state DB handle instead of maintaining its own lazy opener. - The thread archive / descendant traversal paths now use the injected `AgentGraphStore` instead of reaching through local thread-store-specific state. ## Verification - `cargo check -p codex-core -p codex-thread-store -p codex-app-server -p codex-mcp-server -p codex-thread-manager-sample --tests` - `cargo test -p codex-thread-store` - `cargo test -p codex-core thread_manager_accepts_separate_agent_graph_store_and_thread_store -- --nocapture` - `cargo test -p codex-app-server thread_archive_archives_spawned_descendants -- --nocapture` |

[codex] Split tool handlers by tool name (#20687)
## Why Tool registration used to bind a tool name to a handler externally, which left ownership split between the registry plan and the handler implementation. Some built-in handlers also multiplexed multiple in-core tools by switching on the invoked tool name internally. This moves the registry identity onto the handler itself and makes built-in multi-tool areas use separate concrete handlers, so each registered handler instance owns exactly one tool name and one dispatch path. ## What Changed - Added `ToolHandler::tool_name()` and changed `ToolRegistryBuilder::register_handler` to derive the registry key from the handler. - Split built-in multiplexed handlers into concrete per-tool handlers for unified exec, shell/local shell/container exec, MCP resources, goal tools, and agent job tools. - Kept name-carrying handler instances only where the runtime target is inherently external or dynamic, such as MCP tools, dynamic tools, and unavailable placeholders. - Updated `ToolHandlerKind` and registry-plan construction so plan entries map directly to concrete handler registrations. ## Verification - `cargo test -p codex-tools tool_registry_plan` - `cargo test -p codex-core --lib tools::registry_tests` - `just fix -p codex-tools` - `just fix -p codex-core` |

state: pass state db handles through consumers (#20561)
## Why SQLite state was still being opened from consumer paths, including lazy `OnceCell`-backed thread-store call sites. That let one process construct multiple state DB connections for the same Codex home, which makes SQLite lock contention and `database is locked` failures much easier to hit. State DB lifetime should be chosen by main-like entrypoints and tests, then passed through explicitly. Consumers should use the supplied `Option<StateDbHandle>` or `StateDbHandle` and keep their existing filesystem fallback or error behavior when no handle is available. The startup path also needs to keep the rollout crate in charge of SQLite state initialization. Opening `codex_state::StateRuntime` directly bypasses rollout metadata backfill, so entrypoints should initialize through `codex_rollout::state_db` and receive a handle only after required rollout backfills have completed. ## What Changed - Initialize the state DB in main-like entrypoints for CLI, TUI, app-server, exec, MCP server, and the thread-manager sample. - Pass `Option<StateDbHandle>` through `ThreadManager`, `LocalThreadStore`, app-server processors, TUI app wiring, rollout listing/recording, personality migration, shell snapshot cleanup, session-name lookup, and memory/device-key consumers. - Remove the lazy local state DB wrapper from the thread store so non-test consumers use only the supplied handle or their existing fallback path. - Make `codex_rollout::state_db::init` the local state startup path: it opens/migrates SQLite, runs rollout metadata backfill when needed, waits for concurrent backfill workers up to a bounded timeout, verifies completion, and then returns the initialized handle. - Keep optional/non-owning SQLite helpers, such as remote TUI local reads, as open-only paths that do not run startup backfill. - Switch app-server startup from direct `codex_state::StateRuntime::init` to the rollout state initializer so app-server cannot skip rollout backfill. - Collapse split rollout lookup/list APIs so callers use the normal methods with an optional state handle instead of `_with_state_db` variants. - Restore `getConversationSummary(ThreadId)` to delegate through `ThreadStore::read_thread` instead of a LocalThreadStore-specific rollout path special case. - Keep DB-backed rollout path lookup keyed on the DB row and file existence, without imposing the filesystem filename convention on existing DB rows. - Verify readable DB-backed rollout paths against `session_meta.id` before returning them, so a stale SQLite row that points at another thread's JSONL falls back to filesystem search and read-repairs the DB row. - Keep `debug prompt-input` filesystem-only so a one-off debug command does not initialize or backfill SQLite state just to print prompt input. - Keep goal-session test Codex homes alive only in the goal-specific helper, rather than leaking tempdirs from the shared session test helper. - Update tests and call sites to pass explicit state handles where DB behavior is expected and explicit `None` where filesystem-only behavior is intended. ## Validation - `CARGO_TARGET_DIR=/tmp/codex-target-state-db cargo check -p codex-rollout -p codex-thread-store -p codex-app-server -p codex-core -p codex-tui -p codex-exec -p codex-cli --tests` -

Focused coverage updated in `codex-core`: - `rollout_list_find::find_prefers_sqlite_path_by_id` now uses a DB-preferred rollout file with matching `session_meta.id`, so it still verifies that valid SQLite paths win without depending on stale/empty rollout contents. `cargo test -p codex-app-server thread_list_respects_search_term_filter -- --test-threads=1 --nocapture` was attempted locally but timed out waiting for the app-server test harness `initialize` response before reaching the changed thread-list code path. `bazel test //codex-rs/thread-store:thread-store-unit-tests --test_output=errors` was attempted locally after the thread-store fix, but this container failed before target analysis while fetching `v8+` through BuildBuddy/direct GitHub. The equivalent local crate coverage, including `cargo test -p codex-thread-store`, passes. A plain local `cargo check -p codex-rollout -p codex-app-server --tests` also requires system `libcap.pc` for `codex-linux-sandbox`; the follow-up app-server check above used `CODEX_SKIP_VENDORED_BWRAP=1` in this container. |

Make thread store process-scoped (#19474)
- Build one app-server process ThreadStore from startup config and share it with ThreadManager and CodexMessageProcessor. - Remove per-thread/fork store reconstruction so effective thread config cannot switch the persistence backend. - Add params to ThreadStore create/resume for specifying thread metadata, since otherwise the metadata from store creation would be used (incorrectly). |

[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 requested_permissions_trust_project_uses_permission_profile_intent` --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

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`
- `cargo test -p codex-protocol
preserving_deny_entries_keeps_unrestricted_policy_enforceable`
- `cargo test -p codex-app-server-protocol
permission_profile_file_system_permissions`
- `cargo test -p codex-app-server-protocol serialize_client_response`
- `cargo test -p codex-core

- `just fix`
- `just fix -p codex-protocol`
- `just fix -p codex-app-server-protocol`
- `just fix -p codex-core`
- `just fix -p codex-app-server`

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. |
