• Route AGENTS.md loading through environment filesystems (#26205)

  ## Why
  
  Workspace-specific `AGENTS.md` loading needs to use the selected
  environment filesystem so remote workspaces and child agents read
  instructions from their actual environment instead of the host
  filesystem. The app-server should report the same instruction sources
  the initialized thread actually loaded, rather than independently
  rescanning configuration and filesystem state.
  
  ## What changed
  
  - Introduce `LoadedAgentsMd` to retain ordered user, project, and
  internal instructions with their provenance.
  - Load and canonicalize workspace `AGENTS.md` paths through the primary
  `EnvironmentManager` environment, then render the loaded instructions
  when constructing turn context.
  - Expose cached loaded instruction sources from initialized threads and
  use them for app-server start, resume, and fork responses.
  - Preserve global `CODEX_HOME` loading and separator behavior while
  excluding empty project files that did not supply model-visible
  instructions.
  - Add integration coverage for CLI injection, selected-environment
  provenance and rendering, empty environment selection, and cached
  sources on loaded-thread resume.
  
  ## Validation

• core: allow excluding tool namespaces from code mode (#26320)

  ## Why
  
  Research and training setups need to control which tool namespaces
  appear inside code mode's nested `tools` surface without disabling those
  tools entirely. This makes it possible to train against a deliberately
  reduced nested-tool setup while preserving the normal direct and
  deferred tool paths.
  
  ## What
  
  - Extend `features.code_mode` to accept structured configuration while
  preserving the existing boolean syntax.
  - Add an exact `excluded_tool_namespaces` list under
  `[features.code_mode]`:
  
    ```toml
    [features.code_mode]
    enabled = true
    excluded_tool_namespaces = ["mcp__codex_apps", "multi_agent_v1"]
    ```
  
  - Filter matching canonical `ToolName` namespaces when constructing code
  mode's nested router and code-mode-specific direct tool descriptions.
  - Keep excluded tools registered, directly exposed in mixed code mode,
  and discoverable through top-level `tool_search` when otherwise
  eligible.
  - Derive deferred nested-tool guidance after namespace filtering so the
  `exec` description does not advertise excluded-only deferred tools.
  - Preserve the boolean/table representation when materializing config
  locks and update the generated config schema.

  - `just test -p codex-config`

• [codex-analytics] emit forked thread id on initialization (#26248)

  ## Why
  - Thread initialization analytics do not identify the source thread for
  forked threads.
  - The session viewer needs this lineage to construct thread trees.
  - Depends on openai/openai#987854. Do not release this change before
  that backend schema change is deployed.
  
  ## What Changed
  - Adds optional `forked_from_thread_id` to `codex_thread_initialized`.
  - Populates it from the existing thread fork lineage for app-server and
  in-process subagent initialization paths.
  - Keeps it null for non-forked threads.

• Add saved image path hint to standalone image generation (#25947)

  ## Why
  
  Standalone image generation returns image bytes to the model, but the
  model also needs the host artifact path to reference the generated file
  in follow-up work.
  
  ## What changed
  
  - Append the default saved-image path hint alongside the generated image
  tool output.
  - Reuse the existing core image-generation hint text.
  - Pass the thread ID and Codex home directory needed to compute the
  artifact path.
  - Add app-server and extension coverage for the model-visible hint.

• Bridge host-loaded skills into the skills extension (#26172)

  ## Why
  
  The skills extension needs to become the path that exposes local host
  skills without losing the behavior already owned by core skill loading.
  Host skill discovery is not just `$CODEX_HOME/skills`: it also includes
  config layers, bundled-skill settings, plugin roots, runtime extra
  roots, and the filesystem for the selected primary environment.
  
  Rather than making the extension reload host skills and risk drifting
  from that authoritative load, this PR bridges the already-loaded
  per-turn skills outcome into the extension. That lets the extension
  advertise host skills and inject explicit `$skill` prompts while
  preserving the same roots, disabled/hidden state, rendered paths, and
  environment-backed file reads that the legacy path uses.
  
  ## What Changed
  
  - Adds `HostLoadedSkills` in `core-skills` to wrap the turn's
  `SkillLoadOutcome` and read `SKILL.md` through the filesystem that
  loaded that skill.
  - Stores `HostLoadedSkills` in turn extension data for normal turns and
  review turns, so the skills extension can consume the loaded host
  catalog without reloading it.
  - Adds `HostSkillProvider` under `ext/skills/src/provider/host.rs`,
  mapping host-loaded skill metadata into the skills-extension
  catalog/read contract.
  - Registers the host provider by default from
  `codex_skills_extension::install()`.
  - Preserves host skill metadata such as dependencies, disabled state,
  hidden-from-prompt policy, and slash-normalized display paths.
  - Passes host-loaded skills through `SkillListQuery` and
  `SkillReadRequest` so explicit skill invocation reads only resources
  from the loaded host catalog.
  - Adds integration coverage for a real legacy
  `$CODEX_HOME/skills/.../SKILL.md` skill being listed and injected
  through the installed extension.
  
  ## Testing
  
  - Added `installed_extension_loads_host_skills_from_legacy_roots` in
  `ext/skills/tests/skills_extension.rs`.
  - `just test -p codex-skills-extension`

• Gate automatic idle turns in Plan mode (#26147)

  ## Why
  
  Goal idle continuation is extension-triggered model-visible work, so it
  should follow one core-owned rule for when automatic work may start. In
  particular, it should not jump ahead of queued user/client work, start
  while another task is active, or inject a continuation turn while the
  thread is in Plan mode.
  
  Keeping this policy in `try_start_turn_if_idle` avoids passing
  `collaboration_mode` or review-specific state through
  `ThreadLifecycleContributor::on_thread_idle`. Active `/review` is
  covered by the same active-task gate because Review turns are not
  steerable.
  
  ## What Changed
  
  - Teach `Session::try_start_turn_if_idle` to reject automatic idle turns
  in Plan mode, both before reserving an idle turn and after building the
  turn context.
  - Document `CodexThread::try_start_turn_if_idle` as the extension-facing
  gate for automatic idle work, including Plan-mode and active Review-task
  behavior.
  - Add focused coverage for Plan-mode rejection and active Review-task
  rejection without queuing synthetic input.
  
  ## Testing
  
  - `just test -p codex-core try_start_turn_if_idle`

• [codex-analytics] report compaction request token counts (#25946)

  ## Why
  
  Compaction analytics need token counts that better represent the request
  being compacted. The existing session snapshot can diverge from the
  actual remote compaction request after output rewriting, and remote v2
  can use server-side Responses usage when available.
  
  ## What changed
  
  - Add an optional `active_context_tokens_before` override to
  `CompactionAnalyticsAttempt::track(...)` for remote compaction when it
  has a better before-token value than the begin-time session snapshot.
  The local `/compact` path passes no override.
  - For remote v1 `responses_compact`, subtract the estimated token delta
  from pre-compaction output rewriting from the session snapshot, capped
  by locally-added tokens since the last successful API response.
  - For remote v2 `responses_compaction_v2`, use the same bounded
  output-rewrite fallback as remote v1, then overwrite
  `active_context_tokens_before` with server `token_usage.input_tokens`
  from the `response.completed` event when present.
  - Keep the existing v2 compaction-output validation while carrying the
  completed response token usage through `collect_compaction_output`.
  
  ## Verification
  
  - `just fmt`
  - `just test -p codex-core

• cli: add package path from install context (#26189)

  ## Why
  
  Codex package installs include helper binaries in `codex-path`, such as
  the bundled `rg`. Package-layout launches should add that directory
  before user commands run, but standalone launches were missing it while
  npm launches only worked because `codex.js` had its own legacy `PATH`
  rewrite. That made npm and standalone package behavior diverge.
  
  Shell snapshot restoration can also reset `PATH` after runtime setup.
  Any package-owned `PATH` prepend has to be recorded as an explicit
  runtime override so shells, unified exec, and user-shell commands keep
  access to `codex-path` after a snapshot is sourced.
  
  ## Repro
  
  Before this change, a curl-installed package could contain `rg` under
  `codex-path` but still fail to put it on `PATH`:
  
  ```shell
  mkdir /tmp/test-codex-curl
  curl -fsSL https://chatgpt.com/codex/install.sh \
    | CODEX_HOME=/tmp/test-codex-curl CODEX_NON_INTERACTIVE=1 sh
  /tmp/test-codex-curl/packages/standalone/current/bin/codex exec \
    --skip-git-repo-check 'print `which -a rg`'
  find /tmp/test-codex-curl -name rg
  ```
  
  The `which -a rg` output omitted the packaged helper even though `find`
  showed it under
  `/tmp/test-codex-curl/packages/standalone/releases/.../codex-path/rg`.
  
  The npm install path behaved differently only because
  `codex-cli/bin/codex.js` had legacy `PATH` rewriting:
  
  ```shell
  mkdir /tmp/test-codex-npm
  cd /tmp/test-codex-npm
  npm install @openai/codex
  ./node_modules/.bin/codex exec --skip-git-repo-check 'print `which -a rg`'
  ```
  
  That printed the npm package's `vendor/<target>/codex-path/rg` first.
  This PR moves that behavior into Rust-side package launch setup so
  curl/standalone and npm/bun launches agree without JS rewriting `PATH`.
  
  ## What Changed
  
  - `codex-rs/arg0` now uses
  `InstallContext::current().package_layout.path_dir` to prepend the
  package helper directory before any threads are created.
  - Package helper `PATH` setup is independent from the temporary arg0
  alias setup, so `codex-path` is still added even if CODEX_HOME tempdir,
  lock, or symlink setup fails.
  - `codex-rs/install-context` detects the canonical package layout we
  ship: `bin/`, `codex-resources/`, and `codex-path/` next to
  `codex-package.json`.
  - Shell, local unified exec, and user-shell runtimes now record package
  `codex-path` prepends in `explicit_env_overrides`, matching the existing
  zsh-fork behavior so shell snapshots cannot restore over the package
  helper path.
  - Remote unified exec requests do not receive the local app-server
  package path overlay.
  - `codex-cli/bin/codex.js` no longer computes or overrides `PATH`; it
  only locates the native binary in the canonical package layout and
  passes npm/bun management metadata.
  - Added regression tests for `PATH` ordering, package layout detection,
  and shell snapshot preservation of package path prepends.

• Use Windows setup marker as completion signal (#26074)

  # Why
  
  When an organization requires the elevated Windows sandbox, Codex
  launches an elevated helper to provision users, configure firewall and
  ACL rules, and lock persistent sandbox directories.
  
  We observed that closing the helper after setup started could leave the
  machine partially initialized while the TUI still announced **Sandbox
  ready**. Model-only turns continued to work, but the first shell command
  retried setup and failed with Windows cancellation error `1223`.
  
  This was not an enforcement bypass; command execution continued to fail
  closed. The issue was a false readiness signal: `setup_marker.json` was
  written during user provisioning, before the remaining setup stages had
  completed.
  
  # What
  
  Treat `setup_marker.json` as the commit record for Windows sandbox
  setup:
  
  1. Before full or provisioning setup begins, remove the existing marker
  and create the final marker path with a protected ACL.
  2. Keep the marker empty and therefore invalid while setup is in
  progress. Sandbox users cannot read, modify, or replace it.
  3. Run every synchronous setup stage.
  4. After setup succeeds, write the valid marker contents without
  changing its ACL.
  5. After the helper exits successfully, verify the existing readiness
  check before enabling the sandbox.
  
  If setup is canceled or fails, the marker remains invalid and Codex
  reports setup as incomplete instead of announcing readiness.
  
  Refresh-only and read-ACL-only helper runs continue to leave the marker
  untouched. The setup version remains `5` to avoid forcing all existing
  Windows users through elevated setup again.
  
  # Verification
  
  - Added coverage confirming sandbox users cannot read or modify the
  setup marker after elevated setup.
  - Added coverage confirming a successful helper exit without complete
  setup artifacts is rejected.
  - Ran `just test -p codex-windows-sandbox`.

• feat: catalog multi-agent v2 config (#26254)

  ## Why
  
  Model metadata can now select multi-agent v2 even when a user has not
  enabled `features.multi_agent_v2` in their config. Some existing configs
  still set the legacy `agents.max_threads` knob for v1 multi-agent
  behavior, so treating every v2 runtime as incompatible with
  `agents.max_threads` would break users whose only v2 signal came from
  the model catalog.
  
  The incompatible configuration is specifically enabling
  `features.multi_agent_v2` while also setting `agents.max_threads`.
  Catalog-forced v2 should use the v2 concurrency setting and ignore the
  legacy v1 cap instead of rejecting the config.
  
  ## What changed
  
  - Split config validation from runtime concurrency calculation:
  `effective_agent_max_threads` now just returns the effective cap for the
  resolved multi-agent runtime.
  - Added explicit validation for `features.multi_agent_v2` +
  `agents.max_threads` at session startup.
  - Preserved catalog-selected v2 behavior when `features.multi_agent_v2`
  is disabled, so existing configs with `agents.max_threads` keep
  starting.
  - Updated model-runtime selector coverage so a catalog v2 model still
  exposes v2 tools even when `agents.max_threads` is set and the config
  flag is disabled.
  
  ## Validation
  
  - `cargo check -p codex-core --lib`
  - `just test -p codex-core --lib -E

• Expose local image paths to models (#25944)

• core: stop threading SandboxPolicy through exec (#25700)

  ## Why
  
  #25450 attempts a broad `SandboxPolicy` removal across several unrelated
  surfaces, which makes it hard to review and still leaves new helper code
  moving legacy policies around. This PR is a narrower alternative:
  migrate only the exec-side Windows sandbox plumbing so the review can
  focus on one production path and one compatibility boundary.
  
  The goal is to stop threading `SandboxPolicy` through exec code without
  expanding the migration into app-server, protocol, telemetry, config, or
  session behavior.
  
  ## What changed
  
  - Removed `ExecRequest::compatibility_sandbox_policy()`.
  - Changed the Windows restricted-token and elevated filesystem override
  helpers to accept `PermissionProfile` plus the split filesystem/network
  policies instead of a `SandboxPolicy`.
  - Kept the remaining legacy projection local to the writable-root
  comparison that still needs to compare split policy behavior against the
  legacy Windows backend model.
  - Rejected restricted split filesystem policies that still grant
  full-disk writes before using the Windows restricted-token backend,
  preserving the previous clear-failure behavior for profiles that project
  to `ExternalSandbox`.
  - Updated the Windows sandbox override tests to exercise the new call
  shape and cover the full-write split-profile regression.

• skills: resolve per-turn catalogs from turn input context (#26106)

  ## Why
  
  The skills extension needs the resolved turn environments to build a
  real per-turn `SkillListQuery`. The previous `TurnLifecycleContributor`
  hook only had a turn id, so it could only seed a placeholder query and
  never carry the executor authorities that executor-scoped skill routing
  will need.
  
  Moving catalog resolution onto `TurnInputContributor` puts the skills
  extension on the same turn-preparation path that already has the
  environment ids and working directories for the submitted turn, while
  keeping the actual prompt injection work for follow-up changes.
  
  ## What changed
  
  - switch `ext/skills` from `TurnLifecycleContributor` to
  `TurnInputContributor`
  - build `executor_authorities` from `TurnInputContext.environments` and
  pass them through `SkillListQuery`
  - keep storing the resolved catalog in `SkillsTurnState`, but drop the
  placeholder query helper that no longer matches the real data flow
  - update the extension TODOs to reflect that per-turn catalog resolution
  now happens in the turn-input contributor, and that prompt/context
  injection still needs to move later

• Reject MAv2 close_agent self-targets (#26144)

  ## Why
  
  `close_agent` is a parent-owned coordination tool: a worker should
  return its result, then let its parent decide when to close it. Before
  this change, if an MAv2 worker targeted itself, the resolved target
  could flow through the normal close path and ask the agent control layer
  to close the current conversation.
  
  ## What changed
  
  - Reject `close_agent` when the resolved target is the current session's
  `conversation_id`, returning a model-visible error that tells the worker
  to return its result instead.
  - Keep the guard after target resolution so it covers both thread-id
  targets and task-path targets.
  - Add coverage for self-targeting by thread id and by task name in
  `multi_agents_tests.rs`.
  
  Relevant code:

• chore: extract context fragments into dedicated crate (#26122)

  ## Why
  
  `codex-core` currently owns the generic contextual-fragment trait and
  several reusable fragment implementations. That makes it harder for
  other crates to share the same host-owned model-input abstraction
  without depending on all of `codex-core`.
  
  This change extracts the reusable fragment machinery into a small
  `codex-context-fragments` crate so future extension and skills work can
  depend on the fragment abstraction directly.
  
  ## What Changed
  
  - Added the `codex-context-fragments` crate with:
    - `ContextualUserFragment`
    - `FragmentRegistration` / `FragmentRegistrationProxy`
    - additional-context fragment types
  - Moved `SkillInstructions` into `codex-core-skills`, since
  skill-specific rendering belongs with skills rather than generic core
  context machinery.
  - Kept `codex-core` re-exporting the fragment types it still uses
  internally, so existing call sites keep the same shape.
  - Updated Cargo and Bazel workspace metadata for the new crate.

• feat: add extension turn-input contributors (#25959)

  ## Disclaimer
  Do not use for now
  
  ## Why
  
  Extensions can already contribute prompt fragments and request same-turn
  item injection, but there was no host-owned hook for contributing
  structured `ResponseItem`s while Codex is assembling a new turn's
  initial model input. This change adds that seam so extensions can attach
  turn-local input that depends on the submitted user input and resolved
  turn environments without routing through prompt text or late injection.
  
  ## What changed
  
  - add `TurnInputContributor` to `codex_extension_api` and export the new
  `TurnInputContext` / `TurnInputEnvironment` types it receives

• config: express implicit sandbox defaults as permission profiles (#25926)

  ## Why
  
  `PermissionProfile` is becoming the default way to represent Codex
  permissions, but the implicit default behavior should stay the same for
  now:
  
  - trusted projects use `:workspace`
  - untrusted projects also use `:workspace`
  - roots without a trust decision use `:read-only`
  - unsandboxed Windows falls back to `:read-only`
  
  This keeps the existing sandbox semantics while making silent config
  defaults observable as built-in permission profiles instead of treating
  the legacy `SandboxPolicy` projection as the primary shape.
  
  ## What Changed
  
  - Refactored legacy sandbox derivation to resolve the configured sandbox
  mode once, then apply the implicit project fallback only when no sandbox
  mode was configured.
  - Preserved the existing trust-decision fallback: trusted and untrusted
  projects default to workspace-write where supported.
  - Added empty-config coverage asserting that an untrusted project
  resolves to the built-in active permission profile (`:workspace` outside
  unsandboxed Windows).
  
  ## Verification
  
  - `just fmt`
  - `just test -p codex-core 'config::'`
  - `just test -p codex-config`

• config: remove dead profile sandbox fallback (#25943)

  ## Why
  
  `profile_sandbox_mode` was left over from the old selected legacy
  profile path. Production now always derives permissions without that
  value, and legacy profile contents are ignored, so keeping a parameter
  that is always `None` makes `derive_permission_profile` look like it
  still supports a fallback that no longer exists.
  
  ## What Changed
  
  - Removed the `profile_sandbox_mode` argument from
  `ConfigToml::derive_permission_profile`.
  - Updated the production caller and legacy sandbox-policy test helper to
  match.
  - Dropped the stale unselected legacy-profile sandbox test that only
  protected the removed fallback shape.
  
  ## Verification
  
  - `just test -p codex-config`
  - `just test -p codex-core 'config::'`

• Add remote request permissions integration coverage (#25867)

  ## Stack
  
  1. #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. This PR (#25867) - Add remote request permissions integration
  coverage: verifies the selected remote environment across request,
  approval, grant reuse, and exec.
  
  This PR is stacked on #25862 and should be reviewed after #25850,
  #25858, and #25862.
  
  ## Why
  
  The environment-scoped permission stack needs one end-to-end check that
  exercises the CCA-shaped path, not only unit-level parsing. This
  verifies that a model-sent `environmentId` on `request_permissions`
  reaches the approval event, stores the grant under the selected
  environment, and is reused by a later tool call in that same
  environment.
  
  ## What Changed
  
  - Adds a remote executor integration test for `request_permissions` with
  `environmentId: remote` and a relative write root.
  - Asserts the permission event reports the remote environment and cwd,
  and that the normalized grant resolves under the remote cwd.
  - Approves the grant, then runs a remote `exec_command` without explicit
  per-call permissions and verifies it completes without another exec
  approval and writes only in the remote filesystem.
  
  ## Verification
  
  - Not run locally per instruction.

• [codex] Keep hosted tools visible in code-only mode (#25890)

  ## Why
  
  `code_mode_only` moved ordinary runtime tools behind `exec`, but it also
  hid hosted Responses tools. Hosted `web_search` and `image_generation`
  do not have a nested `exec` runtime path, so code-only sessions lost
  those capabilities entirely even when their existing provider, auth,
  model, and configuration gates passed.
  
  ## What changed
  
  - Keep hosted Responses tools top-level in `code_mode_only` sessions
  after their existing gates pass.
  - Preserve the existing nested-tool behavior for ordinary runtimes and
  the direct-only behavior for multi-agent v2 tools.
  - Add planner coverage for `code_mode_only` with default multi-agent v2
  settings, hosted live web search, and hosted image generation.
  
  ## Verification
  
  - Added focused regression coverage in
  `codex-rs/core/src/tools/spec_plan_tests.rs`.
  - Left execution to CI per repository workflow.

• core: stop passing legacy SandboxPolicy to guardian reviews (#25911)

  ## Why
  
  Guardian review turns already submit a read-only `PermissionProfile`,
  which is the permissions model the runtime should honor. Passing the
  equivalent legacy `SandboxPolicy` through `ThreadSettingsOverrides`
  keeps two representations of the same read-only constraint alive on this
  path and makes the guardian flow depend on compatibility plumbing that
  is being phased out.
  
  ## What Changed
  
  - Set `sandbox_policy` to `None` when the guardian review session
  submits its child `Op::UserInput`.
  - Keep `permission_profile: Some(PermissionProfile::read_only())` and
  `approval_policy: Some(AskForApproval::Never)`, so the guardian review
  remains read-only and cannot request approvals.
  - Remove the now-unused `SandboxPolicy` import and redundant comment
  from `codex-rs/core/src/guardian/review_session.rs`.
  
  ## Verification
  
  Not run locally; this is a narrow cleanup of redundant thread-settings
  override state.

• Switch runtime to cloud config bundle (#24622)

  ## Summary
  
  - Adapts the moved `codex-cloud-config` crate from the legacy cloud
  requirements endpoint to the new config bundle endpoint.
  - Switches runtime consumers from `CloudRequirementsLoader` to
  `CloudConfigBundleLoader` so one shared bundle supplies cloud-delivered
  config and requirements.
  - Removes the legacy cloud requirements domain loader path.
  
  ## Details
  
  This intentionally keeps `codex-cloud-config` monolithic for review
  lineage: the previous PR establishes the crate move, and this PR shows
  the behavior change against that moved implementation. A follow-up PR
  splits the module back into focused files.
  
  The new bundle path preserves the important cloud requirements loader
  semantics where intended: account-scoped signed cache, 30 minute TTL, 5
  minute refresh cadence, retry/backoff, auth recovery, and fail-closed
  startup loading. The cached payload changes from a single requirements
  TOML string to the backend-delivered bundle, and validation rejects
  malformed config or requirements fragments before cache write/use.

• Populate workspace kind on Codex turn events (#25135)

  ## Summary
  - carry `workspace_kind` from Responses API client metadata into the
  turn resolved analytics fact
  - serialize the optional value on `codex_turn_event`
  - cover both the turn metadata source and turn event serialization
  
  The `workspace_kind` tells us whether a thread had a project attached vs
  projectless. this is an indicator for who is adopting Codex for
  knowledge work outside of coding
  
  ## Testing
  - `env UV_CACHE_DIR=/private/tmp/uv-cache
  /private/tmp/cargo-tools/bin/just fmt`
  - `env PATH=/private/tmp/cargo-tools/bin:$PATH
  CARGO_HOME=/private/tmp/cargo-home UV_CACHE_DIR=/private/tmp/uv-cache
  /private/tmp/cargo-tools/bin/just test -p codex-analytics`

  CARGO_HOME=/private/tmp/cargo-home UV_CACHE_DIR=/private/tmp/uv-cache
  /private/tmp/cargo-tools/bin/just test -p codex-core turn_metadata`
  
  Paired with openai/openai#970661, which keeps forwarding the same
  metadata key through Responses API headers.

• Propagate permission approval environment id (#25862)

  ## Stack
  
  1. #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. This PR (#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 #25858, and #25867 is stacked on this PR.
  
  ## Why
  
  PR2 lets the model bind a `request_permissions` call to a selected
  environment, but the approval event and client-facing request still
  needed to carry that binding. For CCA, the user-facing prompt and
  delegated approval path should know which environment the grant applies
  to instead of relying on cwd alone.
  
  ## What Changed
  
  - Added optional `environmentId` to `RequestPermissionsEvent`.
  - Emit the selected environment id from core permission approval events.
  - Preserve the environment id through delegate forwarding, including
  cwd-based delegated requests.
  - Added `environmentId` to app-server permission approval params,
  generated schema/TypeScript artifacts, and README examples.
  - Preserve and display the environment id in TUI permission approval
  prompts.
  - Updated focused core, app-server protocol, and TUI conversion
  coverage.

• Route standalone image generation through host finalization md (#25176)

  ## Why
  
  Standalone image-generation extensions emitted turn items through the
  low-level event path, bypassing host-owned finalization such as image
  persistence and contributor processing. At the same time, the
  generated-image save-path hint must remain visible to the model through
  the extension tool's `FunctionCallOutput`, rather than the legacy
  built-in developer-message path.
  
  ## What changed
  
  - Extended `ExtensionTurnItem` to support image-generation items while
  keeping the extension-facing emitter API limited to `emit_started` and
  `emit_completed`.
  - Routed extension completion through core `finalize_turn_item`, so
  standalone image-generation items receive host-owned processing and
  persisted `saved_path` values before publication.
  - Kept legacy built-in image generation on its existing
  developer-message hint path, while standalone image generation returns
  its deterministic saved-path hint in `FunctionCallOutput`.
  - Shared the image artifact path and output-hint formatting used by core
  and the image-generation extension.
  - Passed thread identity through extension tool calls so standalone
  image generation can construct the same intended artifact path as core.
  - Added an app-server integration test covering real standalone image
  generation, saved artifact publication, model-visible output hint
  wiring, and absence of the legacy developer-message hint.
  
  ## Validation
  
  - `just fmt`
  - `just test -p codex-image-generation-extension`
  - `just test -p codex-web-search-extension`

• Add environmentId to request_permissions (#25858)

  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

  4. #25867 - Add remote request permissions integration coverage:

  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.

  ## Stack

  2. #25858 - Add `environmentId` to `request_permissions`: lets the model

  #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

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

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

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

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

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

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

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

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

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

• Test runtime selector before first turn (#25724)

  Stack split from #25708. Original PR intentionally left open. This fifth
  PR adds coverage that a remotely selected multi-agent runtime is applied
  when the model is selected before the first turn.

• Test remote multi-agent runtime selector override (#25723)

  Stack split from #25708. Original PR intentionally left open. This
  fourth PR adds coverage that remote model multi-agent runtime selectors
  override local feature flag defaults.

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

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

• [codex] Move plugin discoverable logic into core-plugins (#25783)

  ## Summary
  - Move plugin discoverable recommendation filtering from `codex-core`
  into `codex-core-plugins` behind `ToolSuggestPluginDiscoveryInput`.
  - Keep `codex-core` as a thin adapter from `Config` to the core-plugins
  API and back to `DiscoverablePluginInfo`.
  - Keep the existing discoverable allowlist private to the core-plugins
  implementation.
  
  ## Validation
  - `just fmt`
  - `just test -p codex-core list_tool_suggest_discoverable_plugins`
  - `git diff --check`
  - Read-only subagent review: no findings

• [codex] Cache remote plugin catalog for suggestions (#25457)

  ## Summary
  - cache the global remote plugin catalog when remote plugin listing runs
  and warm it during startup
  - use the cached remote catalog in plugin install recommendations with
  canonical `plugin@openai-curated-remote` ids
  - reuse the session `PluginsManager` for plugin recommendations so
  remote cache state is visible on the recommend path
  - skip core installed-state verification for remote plugin install
  suggestions while leaving local plugin and connector verification
  unchanged
  
  ## Testing
  - `just fmt`
  - `git diff --check`
  - `cargo test -p codex-core
  list_tool_suggest_discoverable_plugins_includes_cached_remote_global_plugins`
  - `cargo test -p codex-core
  remote_plugin_install_suggestions_skip_core_installed_verification`
  - `cargo test -p codex-app-server
  plugin_list_includes_remote_marketplaces_when_remote_plugin_enabled`
  
  Earlier focused checks during the same branch: codex-tools TUI filter
  test, request_plugin_install tests, and codex-app-server build.
