gt-oaiandGitHub b3095679ed Allow hooks to error (#11615)
Allow hooks to return errors. 

We should do this before introducing more hook types, or we'll have to
migrate them all.

Anton PanasenkoandGitHub 02abd9a8ea feat: persist and restore codex app's tools after search (#11780)
### What changed
1. Removed per-turn MCP selection reset in `core/src/tasks/mod.rs`.
2. Added `SessionState::set_mcp_tool_selection(Vec<String>)` in
`core/src/state/session.rs` for authoritative restore behavior (deduped,
order-preserving, empty clears).
3. Added rollout parsing in `core/src/codex.rs` to recover
`active_selected_tools` from prior `search_tool_bm25` outputs:
   - tracks matching `call_id`s
   - parses function output text JSON
   - extracts `active_selected_tools`
   - latest valid payload wins
   - malformed/non-matching payloads are ignored
4. Applied restore logic to resumed and forked startup paths in
`core/src/codex.rs`.
5. Updated instruction text to session/thread scope in
`core/templates/search_tool/tool_description.md`.
6. Expanded tests in `core/tests/suite/search_tool.rs`, plus unit
coverage in:
   - `core/src/codex.rs`
   - `core/src/state/session.rs`

### Behavior after change
1. Search activates matched tools.
2. Additional searches union into active selection.
3. Selection survives new turns in the same thread.
4. Resume/fork restores selection from rollout history.
5. Separate threads do not inherit selection unless forked.

b527ee2890 feat(core): add structured network approval plumbing and policy decision model (#11672)
### Description
#### Summary
Introduces the core plumbing required for structured network approvals

#### What changed
- Added structured network policy decision modeling in core.
- Added approval payload/context types needed for network approval
semantics.
- Wired shell/unified-exec runtime plumbing to consume structured
decisions.
- Updated related core error/event surfaces for structured handling.
- Updated protocol plumbing used by core approval flow.
- Included small CLI debug sandbox compatibility updates needed by this
layer.

#### Why
establishes the minimal backend foundation for network approvals without
yet changing high-level orchestration or TUI behavior.

#### Notes
- Behavior remains constrained by existing requirements/config gating.
- Follow-up PRs in the stack handle orchestration, UX, and app-server
integration.

Curtis 'Fjord' HawthorneandGitHub 0d76d029b7 Fix js_repl in-flight tool-call waiter race (#11800)
## Summary

This PR fixes a race in `js_repl` tool-call draining that could leave an
exec waiting indefinitely for in-flight tool calls to finish.

The fix is in:

-
`/Users/fjord/code/codex-jsrepl-seq/codex-rs/core/src/tools/js_repl/mod.rs`

## Problem

`js_repl` tracks in-flight tool calls per exec and waits for them to
drain on completion/timeout/cancel paths.
The previous wait logic used a check-then-wait pattern with `Notify`
that could miss a wakeup:

1. Observe `in_flight > 0`
2. Drop lock
3. Register wait (`notified().await`)

If `notify_waiters()` happened between (2) and (3), the waiter could
sleep until another notification that never comes.

## What changed

- Updated all exec-tool-call wait loops to create an owned notification
future while holding the lock:
- use `Arc<Notify>::notified_owned()` instead of cloning notify and
awaiting later.
- Applied this consistently to:
  - `wait_for_exec_tool_calls`
  - `wait_for_all_exec_tool_calls`
  - `wait_for_exec_tool_calls_map`

This preserves existing behavior while eliminating the lost-wakeup
window.

## Test coverage

Added a regression test:

- `wait_for_exec_tool_calls_map_drains_inflight_calls_without_hanging`

The test repeatedly races waiter/finisher tasks and asserts bounded
completion to catch hangs.

## Impact

- No API changes.
- No user-facing behavior changes intended.
- Improves reliability of exec lifecycle boundaries when tool calls are
still in flight.

Curtis 'Fjord' HawthorneandGitHub 6cbb489e6e Fix js_repl view_image test runtime panic (#11796)
## Summary
Fixes a flaky/panicking `js_repl` image-path test by running it on a
multi-thread Tokio runtime and tightening assertions to focus on real
behavior.

## Problem
`js_repl_can_attach_image_via_view_image_tool` in  

`/Users/fjord/code/codex-jsrepl-seq/codex-rs/core/src/tools/js_repl/mod.rs`
can panic under single-thread test runtime with:

`can call blocking only when running on the multi-threaded runtime`

It also asserted a brittle user-facing text string.

## Changes
1. Updated the test runtime to:
   `#[tokio::test(flavor = "multi_thread", worker_threads = 2)]`
2. Removed the brittle `"attached local image path"` string assertion.
3. Kept the concrete side-effect assertions:
   - tool call succeeds
- image is actually injected into pending input (`InputImage` with
`data:image/png;base64,...`)

## Why this is safe
This is test-only behavior. No production runtime code paths are
changed.

## Validation
- Ran:
`cargo test -p codex-core
tools::js_repl::tests::js_repl_can_attach_image_via_view_image_tool --
--nocapture`
- Result: pass

Curtis 'Fjord' HawthorneandGitHub a02342c9e1 Add js_repl kernel crash diagnostics (#11666)
## Summary

This PR improves `js_repl` crash diagnostics so kernel failures are
debuggable without weakening timeout/reset guarantees.

## What Changed

- Added bounded kernel stderr capture and truncation logic (line + byte
caps).
- Added structured kernel snapshots (`pid`, exit status, stderr tail)
for failure paths.
- Enriched model-visible kernel-failure errors with a structured
diagnostics payload:
  - `js_repl diagnostics: {...}`
  - Included only for likely kernel-failure write/EOF cases.
- Improved logging around kernel write failures, unexpected exits, and
kill/wait paths.
- Added/updated unit tests for:
  - UTF-8-safe truncation
  - stderr tail bounds
  - structured diagnostics shape/truncation
  - conditional diagnostics emission
  - timeout kill behavior
  - forced kernel-failure diagnostics

## Why

Before this, failures like broken pipe / unexpected kernel exit often
surfaced as generic errors with little context. This change preserves
existing behavior but adds actionable diagnostics while keeping output
bounded.

## Scope

- Code changes are limited to:
-
`/Users/fjord/code/codex-jsrepl-seq/codex-rs/core/src/tools/js_repl/mod.rs`

## Validation

- `cargo clippy -p codex-core --all-targets -- -D warnings`
- Targeted `codex-core` js_repl unit tests (including new
diagnostics/timeout coverage)
- Tried starting a long running js_repl command (sleep for 10 minutes),
verified error output was as expected after killing the node process.

Anton PanasenkoandGitHub 38c442ca7f core: limit search_tool_bm25 to Apps and clarify discovery guidance (#11669)
## Summary
- Limit `search_tool_bm25` indexing to `codex_apps` tools only, so
non-Apps MCP servers are no longer discoverable through this search
path.
- Move search-tool discovery guidance into the `search_tool_bm25` tool
description (via template include) instead of injecting it as a separate
developer message.
- Update Apps discovery guidance wording to clarify when to use
`search_tool_bm25` for Apps-backed systems (for example Slack, Google
Drive, Jira, Notion) and when to call tools directly.
- Remove dead `core` helper code (`filter_codex_apps_mcp_tools` and
`codex_apps_connector_id`) that is no longer used after the
tool-selection refactor.
- Update `core` search-tool tests to assert codex-apps-only behavior and
to validate guidance from the tool description.

## Validation
-  `just fmt`
-  `cargo test -p codex-core search_tool`
- ⚠️ `cargo test -p codex-core` was attempted, but the run repeatedly
stalled on
`tools::js_repl::tests::js_repl_can_attach_image_via_view_image_tool`.

Michael BolinandGitHub a4cc1a4a85 feat: introduce Permissions (#11633)
## Why
We currently carry multiple permission-related concepts directly on
`Config` for shell/unified-exec behavior (`approval_policy`,
`sandbox_policy`, `network`, `shell_environment_policy`,
`windows_sandbox_mode`).

Consolidating these into one in-memory struct makes permission handling
easier to reason about and sets up the next step: supporting named
permission profiles (`[permissions.PROFILE_NAME]`) without changing
behavior now.

This change is mostly mechanical: it updates existing callsites to go
through `config.permissions`, but it does not yet refactor those
callsites to take a single `Permissions` value in places where multiple
permission fields are still threaded separately.

This PR intentionally **does not** change the on-disk `config.toml`
format yet and keeps compatibility with legacy config keys.

## What Changed
- Introduced `Permissions` in `core/src/config/mod.rs`.
- Added `Config::permissions` and moved effective runtime permission
fields under it:
  - `approval_policy`
  - `sandbox_policy`
  - `network`
  - `shell_environment_policy`
  - `windows_sandbox_mode`
- Updated config loading/building so these effective values are still
derived from the same existing config inputs and constraints.
- Updated Windows sandbox helpers/resolution to read/write via
`permissions`.
- Threaded the new field through all permission consumers across core
runtime, app-server, CLI/exec, TUI, and sandbox summary code.
- Updated affected tests to reference `config.permissions.*`.
- Renamed the struct/field from
`EffectivePermissions`/`effective_permissions` to
`Permissions`/`permissions` and aligned variable naming accordingly.

## Verification
- `just fix -p codex-core -p codex-tui -p codex-cli -p codex-app-server
-p codex-exec -p codex-utils-sandbox-summary`
- `cargo build -p codex-core -p codex-tui -p codex-cli -p
codex-app-server -p codex-exec -p codex-utils-sandbox-summary`

Curtis 'Fjord' HawthorneandGitHub 466be55abc Add js_repl host helpers and exec end events (#10672)
## Summary

This PR adds host-integrated helper APIs for `js_repl` and updates model
guidance so the agent can use them reliably.

### What’s included

- Add `codex.tool(name, args?)` in the JS kernel so `js_repl` can call
normal Codex tools.
- Keep persistent JS state and scratch-path helpers available:
  - `codex.state`
  - `codex.tmpDir`
- Wire `js_repl` tool calls through the standard tool router path.
- Add/align `js_repl` execution completion/end event behavior with
existing tool logging patterns.
- Update dynamic prompt injection (`project_doc`) to document:
  - how to call `codex.tool(...)`
  - raw output behavior
- image flow via `view_image` (`codex.tmpDir` +
`codex.tool("view_image", ...)`)
- stdio safety guidance (`console.log` / `codex.tool`, avoid direct
`process.std*`)

## Why

- Standardize JS-side tool usage on `codex.tool(...)`
- Make `js_repl` behavior more consistent with existing tool execution
and event/logging patterns.
- Give the model enough runtime guidance to use `js_repl` safely and
effectively.

## Testing

- Added/updated unit and runtime tests for:
  - `codex.tool` calls from `js_repl` (including shell/MCP paths)
  - image handoff flow via `view_image`
  - prompt-injection text for `js_repl` guidance
  - execution/end event behavior and related regression coverage

Owen LinandGitHub efc8d45750 feat(app-server): experimental flag to persist extended history (#11227)
This PR adds an experimental `persist_extended_history` bool flag to
app-server thread APIs so rollout logs can retain a richer set of
EventMsgs for non-lossy Thread > Turn > ThreadItems reconstruction (i.e.
on `thread/resume`).

### Motivation
Today, our rollout recorder only persists a small subset (e.g. user
message, reasoning, assistant message) of `EventMsg` types, dropping a
good number (like command exec, file change, etc.) that are important
for reconstructing full item history for `thread/resume`, `thread/read`,
and `thread/fork`.

Some clients want to be able to resume a thread without lossiness. This
lossiness is primarily a UI thing, since what the model sees are
`ResponseItem` and not `EventMsg`.

### Approach
This change introduces an opt-in `persist_full_history` flag to preserve
those events when you start/resume/fork a thread (defaults to `false`).

This is done by adding an `EventPersistenceMode` to the rollout
recorder:
- `Limited` (existing behavior, default)
- `Extended` (new opt-in behavior)

In `Extended` mode, persist additional `EventMsg` variants needed for
non-lossy app-server `ThreadItem` reconstruction. We now store the
following ThreadItems that we didn't before:
- web search
- command execution
- patch/file changes
- MCP tool calls
- image view calls
- collab tool outcomes
- context compaction
- review mode enter/exit

For **command executions** in particular, we truncate the output using
the existing `truncate_text` from core to store an upper bound of 10,000
bytes, which is also the default value for truncating tool outputs shown
to the model. This keeps the size of the rollout file and command
execution items returned over the wire reasonable.

And we also persist `EventMsg::Error` which we can now map back to the
Turn's status and populates the Turn's error metadata.

#### Updates to EventMsgs
To truly make `thread/resume` non-lossy, we also needed to persist the
`status` on `EventMsg::CommandExecutionEndEvent` and
`EventMsg::PatchApplyEndEvent`. Previously it was not obvious whether a
command failed or was declined (similar for apply_patch). These
EventMsgs were never persisted before so I made it a required field.

Michael BolinandGitHub abbd74e2be feat: make sandbox read access configurable with ReadOnlyAccess (#11387)
`SandboxPolicy::ReadOnly` previously implied broad read access and could
not express a narrower read surface.
This change introduces an explicit read-access model so we can support
user-configurable read restrictions in follow-up work, while preserving
current behavior today.

It also ensures unsupported backends fail closed for restricted-read
policies instead of silently granting broader access than intended.

## What

- Added `ReadOnlyAccess` in protocol with:
  - `Restricted { include_platform_defaults, readable_roots }`
  - `FullAccess`
- Updated `SandboxPolicy` to carry read-access configuration:
  - `ReadOnly { access: ReadOnlyAccess }`
  - `WorkspaceWrite { ..., read_only_access: ReadOnlyAccess }`
- Preserved existing behavior by defaulting current construction paths
to `ReadOnlyAccess::FullAccess`.
- Threaded the new fields through sandbox policy consumers and call
sites across `core`, `tui`, `linux-sandbox`, `windows-sandbox`, and
related tests.
- Updated Seatbelt policy generation to honor restricted read roots by
emitting scoped read rules when full read access is not granted.
- Added fail-closed behavior on Linux and Windows backends when
restricted read access is requested but not yet implemented there
(`UnsupportedOperation`).
- Regenerated app-server protocol schema and TypeScript artifacts,
including `ReadOnlyAccess`.

## Compatibility / rollout

- Runtime behavior remains unchanged by default (`FullAccess`).
- API/schema changes are in place so future config wiring can enable
restricted read access without another policy-shape migration.

Curtis 'Fjord' HawthorneandGitHub 42e22f3bde Add feature-gated freeform js_repl core runtime (#10674)
## Summary

This PR adds an **experimental, feature-gated `js_repl` core runtime**
so models can execute JavaScript in a persistent REPL context across
tool calls.

The implementation integrates with existing feature gating, tool
registration, prompt composition, config/schema docs, and tests.

## What changed

- Added new experimental feature flag: `features.js_repl`.
- Added freeform `js_repl` tool and companion `js_repl_reset` tool.
- Gated tool availability behind `Feature::JsRepl`.
- Added conditional prompt-section injection for JS REPL instructions
via marker-based prompt processing.
- Implemented JS REPL handlers, including freeform parsing and pragma
support (timeout/reset controls).
- Added runtime resolution order for Node:
  1. `CODEX_JS_REPL_NODE_PATH`
  2. `js_repl_node_path` in config
  3. `PATH`
- Added JS runtime assets/version files and updated docs/schema.

## Why

This enables richer agent workflows that require incremental JavaScript
execution with preserved state, while keeping rollout safe behind an
explicit feature flag.

## Testing

Coverage includes:

- Feature-flag gating behavior for tool exposure.
- Freeform parser/pragma handling edge cases.
- Runtime behavior (state persistence across calls and top-level `await`
support).

## Usage

```toml
[features]
js_repl = true
```

Optional runtime override:

- `CODEX_JS_REPL_NODE_PATH`, or
- `js_repl_node_path` in config.

Michael BolinandGitHub 476c1a7160 Remove test-support feature from codex-core and replace it with explicit test toggles (#11405)
## Why

`codex-core` was being built in multiple feature-resolved permutations
because test-only behavior was modeled as crate features. For a large
crate, those permutations increase compile cost and reduce cache reuse.

## Net Change

- Removed the `test-support` crate feature and related feature wiring so
`codex-core` no longer needs separate feature shapes for test consumers.
- Standardized cross-crate test-only access behind
`codex_core::test_support`.
- External test code now imports helpers from
`codex_core::test_support`.
- Underlying implementation hooks are kept internal (`pub(crate)`)
instead of broadly public.

## Outcome

- Fewer `codex-core` build permutations.
- Better incremental cache reuse across test targets.
- No intended production behavior change.

62d0f302fd fix(core): canonicalize wrapper approvals and support heredoc prefix … (#10941)
## Summary
- Reduced repeated approvals for equivalent wrapper commands and fixed
execpolicy matching for heredoc-style shell invocations, with minimal
behavior change and fail-closed defaults.

## Fixes
1. Canonicalized approval matching for wrappers so equivalent commands
map to the same approval intent.
2. Added heredoc-aware prefix extraction for execpolicy so commands like
`python3 <<'PY' ... PY` match rules such as `prefix_rule(["python3"],
...)`.
3. Kept fallback behavior conservative: if parsing is ambiguous,
existing prompt behavior is preserved.

## Edge Cases Covered
- Wrapper path/name differences: `/bin/bash` vs `bash`, `/bin/zsh` vs
`zsh`.
- Shell modes: `-c` and `-lc`.
- Heredoc forms: quoted delimiter (`<<'PY'`) and unquoted delimiter (`<<
PY`).
- Multi-command heredoc scripts are rejected by the fallback
- Non-heredoc redirections (`>`, etc.) are not treated as heredoc prefix
matches.
- Complex scripts still fall back to prior behavior rather than
expanding permissions.

Michael BolinandGitHub 44ebf4588f feat: retain NetworkProxy, when appropriate (#11207)
As of this PR, `SessionServices` retains a
`Option<StartedNetworkProxy>`, if appropriate.

Now the `network` field on `Config` is `Option<NetworkProxySpec>`
instead of `Option<NetworkProxy>`.

Over in `Session::new()`, we invoke `NetworkProxySpec::start_proxy()` to
create the `StartedNetworkProxy`, which is a new struct that retains the
`NetworkProxy` as well as the `NetworkProxyHandle`. (Note that `Drop` is
implemented for `NetworkProxyHandle` to ensure the proxies are shutdown
when it is dropped.)

The `NetworkProxy` from the `StartedNetworkProxy` is threaded through to
the appropriate places.

tool-specific variants)
- harden macOS Seatbelt network policy generation to route through
inferred loopback proxy endpoints and fail closed when proxy env is
malformed
- thread proxy-aware Linux sandbox flags and add minimal bwrap netns
isolation hook for restricted non-proxy runs
- add/refresh tests for proxy env wiring, Seatbelt policy generation,
and Linux sandbox argument wiring

Anton PanasenkoandGitHub becc3a0424 feat: search_tool (#10657)
**Why We Did This**
- The goal is to reduce MCP tool context pollution by not exposing the
full MCP tool list up front
- It forces an explicit discovery step (`search_tool_bm25`) so the model
narrows tool scope before making MCP calls, which helps relevance and
lowers prompt/tool clutter.

**What It Changed**
- Added a new experimental feature flag `search_tool` in
`core/src/features.rs:90` and `core/src/features.rs:430`.
- Added config/schema support for that flag in
`core/config.schema.json:214` and `core/config.schema.json:1235`.
- Added BM25 dependency (`bm25`) in `Cargo.toml:129` and
`core/Cargo.toml:23`.
- Added new tool handler `search_tool_bm25` in
`core/src/tools/handlers/search_tool_bm25.rs:18`.
- Registered the handler and tool spec in
`core/src/tools/handlers/mod.rs:11` and `core/src/tools/spec.rs:780` and
`core/src/tools/spec.rs:1344`.
- Extended `ToolsConfig` to carry `search_tool` enablement in
`core/src/tools/spec.rs:32` and `core/src/tools/spec.rs:56`.
- Injected dedicated developer instructions for tool-discovery workflow
in `core/src/codex.rs:483` and `core/src/codex.rs:1976`, using
`core/templates/search_tool/developer_instructions.md:1`.
- Added session state to store one-shot selected MCP tools in
`core/src/state/session.rs:27` and `core/src/state/session.rs:131`.
- Added filtering so when feature is enabled, only selected MCP tools
are exposed on the next request (then consumed) in
`core/src/codex.rs:3800` and `core/src/codex.rs:3843`.
- Added E2E suite coverage for
enablement/instructions/hide-until-search/one-turn-selection in
`core/tests/suite/search_tool.rs:72`,
`core/tests/suite/search_tool.rs:109`,
`core/tests/suite/search_tool.rs:147`, and
`core/tests/suite/search_tool.rs:218`.
- Refactored test helper utilities to support config-driven tool
collection in `core/tests/suite/tools.rs:281`.

**Net Behavioral Effect**
- With `search_tool` **off**: existing MCP behavior (tools exposed
normally).
- With `search_tool` **on**: MCP tools start hidden, model must call
`search_tool_bm25`, and only returned `selected_tools` are available for
the next model call.

Michael BolinandGitHub 383b45279e feat: include NetworkConfig through ExecParams (#11105)
This PR adds the following field to `Config`:

```rust
pub network: Option<NetworkProxy>,
```

Though for the moment, it will always be initialized as `None` (this
will be addressed in a subsequent PR).

This PR does the work to thread `network` through to `execute_exec_env()`, `process_exec_tool_call()`, and `UnifiedExecRuntime.run()` to ensure it is available whenever we span a process.

Eric TrautandGitHub b3de6c7f2b Defer persistence of rollout file (#11028)
- Defer rollout persistence for fresh threads (`InitialHistory::New`):
keep rollout events in memory and only materialize rollout file + state
DB row on first `EventMsg::UserMessage`.
- Keep precomputed rollout path available before materialization.
- Change `thread/start` to build thread response from live config
snapshot and optional precomputed path.
- Improve pre-materialization behavior in app-server/TUI: clearer
invalid-request errors for file-backed ops and a friendlier `/fork` “not
ready yet” UX.
- Update tests to match deferred semantics across
start/read/archive/unarchive/fork/resume/review flows.
- Improved resilience of user_shell test, which should be unrelated to
this change but must be affected by timing changes

For Reviewers:
* The primary change is in recorder.rs
* Most of the other changes were to fix up broken assumptions in
existing tests

Testing:
* Manually tested CLI
* Exercised app server paths by manually running IDE Extension with
rebuilt CLI binary
* Only user-visible change is that `/fork` in TUI generates visible
error if used prior to first turn

Charley CunninghamandGitHub 41b4962b0a Sync collaboration mode naming across Default prompt, tools, and TUI (#10666)
## Summary
- add shared `ModeKind` helpers for display names, TUI visibility, and
`request_user_input` availability
- derive TUI mode filtering/labels from shared `ModeKind` metadata
instead of local hardcoded matches
- derive `request_user_input` availability text and unavailable error
mode names from shared mode metadata
- replace hardcoded known mode names in the Default collaboration-mode
template with `{{KNOWN_MODE_NAMES}}` and fill it from
`TUI_VISIBLE_COLLABORATION_MODES`
- add regression tests for mode metadata sync and placeholder
replacement

## Notes
- `cargo test -p codex-core` integration target (`tests/all`) still
shows pre-existing env-specific failures in this environment due missing
`test_stdio_server` binary resolution; core unit tests are green.

Owen LinandGitHub 5ea107a088 feat(app-server, core): allow text + image content items for dynamic tool outputs (#10567)
Took over the work that @aaronl-openai started here:
https://github.com/openai/codex/pull/10397

Now that app-server clients are able to set up custom tools (called
`dynamic_tools` in app-server), we should expose a way for clients to
pass in not just text, but also image outputs. This is something the
Responses API already supports for function call outputs, where you can
pass in either a string or an array of content outputs (text, image,
file):
https://platform.openai.com/docs/api-reference/responses/create#responses_create-input-input_item_list-item-function_tool_call_output-output-array-input_image

So let's just plumb it through in Codex (with the caveat that we only
support text and image for now). This is implemented end-to-end across
app-server v2 protocol types and core tool handling.

## Breaking API change
NOTE: This introduces a breaking change with dynamic tools, but I think
it's ok since this concept was only recently introduced
(https://github.com/openai/codex/pull/9539) and it's better to get the
API contract correct. I don't think there are any real consumers of this
yet (not even the Codex App).

Old shape:
`{ "output": "dynamic-ok", "success": true }`

New shape:
```
{
    "contentItems": [
      { "type": "inputText", "text": "dynamic-ok" },
      { "type": "inputImage", "imageUrl": "data:image/png;base64,AAA" }
    ]
  "success": true
}
```

viyatb-oaiandGitHub ae4de43ccc feat(linux-sandbox): add bwrap support (#9938)
## Summary
This PR introduces a gated Bubblewrap (bwrap) Linux sandbox path. The
curent Linux sandbox path relies on in-process restrictions (including
Landlock). Bubblewrap gives us a more uniform filesystem isolation
model, especially explicit writable roots with the option to make some
directories read-only and granular network controls.

This is behind a feature flag so we can validate behavior safely before
making it the default.

- Added temporary rollout flag:
  - `features.use_linux_sandbox_bwrap`
- Preserved existing default path when the flag is off.
- In Bubblewrap mode:
- Added internal retry without /proc when /proc mount is not permitted
by the host/container.

Charley CunninghamandGitHub 998eb8f32b Improve Default mode prompt (less confusion with Plan mode) (#10545)
## Summary

This PR updates `request_user_input` behavior and Default-mode guidance
to match current collaboration-mode semantics and reduce model
confusion.

## Why

- `request_user_input` should be explicitly documented as **Plan-only**.
- Tool description and runtime availability checks should be driven by
the **same centralized mode policy**.
- Default mode prompt needed stronger execution guidance and explicit
instruction that `request_user_input` is unavailable.
- Error messages should report the **actual mode name** (not aliases
that can read as misleading).

## What changed

- Centralized `request_user_input` mode policy in `core` handler logic:
  - Added a single allowed-modes config (`Plan` only).
  - Reused that policy for:
    - runtime rejection messaging
    - tool description text
- Updated tool description to include availability constraint:
  - `"This tool is only available in Plan mode."`
- Updated runtime rejection behavior:
  - `Default` -> `"request_user_input is unavailable in Default mode"`
  - `Execute` -> `"request_user_input is unavailable in Execute mode"`
- `PairProgramming` -> `"request_user_input is unavailable in Pair
Programming mode"`
- Strengthened Default collaboration prompt:
  - Added explicit execution-first behavior
  - Added assumptions-first guidance
  - Added explicit `request_user_input` unavailability instruction
  - Added concise progress-reporting expectations
- Simplified formatting implementation:
  - Inlined allowed-mode name collection into `format_allowed_modes()`
- Kept `format_allowed_modes()` output for 3+ modes as CSV style
(`modes: a,b,c`)
