Michael Bolin 986c60467b windows-sandbox: pass workspace roots to runner (#24108) 
## Why

#23813 switches the Windows sandbox runner path to `PermissionProfile`,
but it still left one runtime anchor for resolving symbolic
`:workspace_roots` entries. That is not enough once a turn has multiple
effective workspace roots: exact entries and deny globs under
`:workspace_roots` need to be materialized for every runtime root before
the command runner chooses token mode or builds ACL plans.

## What Changed

- Replaces the Windows runner/setup `permission_profile_cwd` plumbing
with `workspace_roots: Vec<AbsolutePathBuf>`.
- Resolves Windows-local `PermissionProfile` data with
`materialize_project_roots_with_workspace_roots(...)` instead of the
single-cwd helper.
- Threads `Config::effective_workspace_roots()` through core execution,
unified exec, TUI setup/read-grant flows, app-server setup, app-server
`command/exec`, and `debug sandbox` on Windows.
- Preserves those workspace roots through the zsh-fork escalation
executor instead of rebuilding them from `sandbox_policy_cwd`.
- Makes `ExecRequest::new(...)` and the remaining
`build_exec_request(...)` helper path take
`windows_sandbox_workspace_roots` explicitly so new call sites cannot
silently fall back to `vec![cwd]`.
- Clarifies the `debug sandbox` non-Windows comment: remaining
cwd-dependent resolution still uses `sandbox_policy_cwd`, while
`:workspace_roots` entries are already materialized from config roots.
- Updates elevated runner IPC `SpawnRequest` to send `workspace_roots`
and bumps the framed IPC protocol version to `3` for the payload shape
change.
- Adds Windows-local resolver coverage for expanding exact and glob
`:workspace_roots` entries across multiple roots, plus core helper
coverage proving explicit roots are preserved.

## Verification

- `cargo check -p codex-windows-sandbox -p codex-core -p codex-tui -p
codex-cli -p codex-app-server`
- `cargo test -p codex-windows-sandbox`
- `cargo test -p codex-core windows_sandbox`
- `cargo test -p codex-core unix_escalation`
- `cargo test -p codex-app-server windows_sandbox`
- `cargo test -p codex-tui windows_sandbox`
- `cargo test -p codex-cli debug_sandbox`
- `just test -p codex-core unified_exec`
- `just test -p codex-core
build_exec_request_preserves_windows_workspace_roots`
- `env -u CODEX_NETWORK_PROXY_ACTIVE -u
CODEX_NETWORK_ALLOW_LOCAL_BINDING just test -p codex-app-server --lib
command_exec`
- `just test -p codex-windows-sandbox`
- `just test -p codex-exec sandbox`
- `just fix -p codex-core -p codex-app-server -p codex-windows-sandbox`

A local macOS cross-check with `cargo check --target
x86_64-pc-windows-msvc ...` did not reach crate Rust code because native
dependencies require Windows SDK headers (`windows.h` / `assert.h`) in
this environment; Windows CI remains the real target validation.

Two local targeted filters compile but do not run assertions on macOS:
`env -u CODEX_NETWORK_PROXY_ACTIVE -u CODEX_NETWORK_ALLOW_LOCAL_BINDING
just test -p codex-app-server --lib command_exec_processor` matched zero
tests, and `just test -p codex-linux-sandbox landlock` matched zero
tests because the landlock suite is Linux-only.

Michael Bolin 0a6bc4e687 windows-sandbox: remove SandboxPolicy runner plumbing (#23813) 
## Why

The Windows sandbox runner still carried the old `SandboxPolicy`
compatibility path even though core now computes `PermissionProfile`.
That meant Windows command-runner execution could only see the legacy
projection, so profile-only filesystem rules such as deny globs were not
part of the runner input.

## What Changed

- Removed the Windows-local `SandboxPolicy` parser/export and deleted
`windows-sandbox-rs/src/policy.rs`.
- Changed restricted-token capture/session setup, elevated setup,
world-writable audit, read-root grant, and command-runner session APIs
to accept `PermissionProfile` plus the profile cwd.
- Bumped the elevated command-runner IPC protocol to version 2 because
`SpawnRequest` now carries `permission_profile` /
`permission_profile_cwd` instead of the legacy `policy_json_or_preset` /
`sandbox_policy_cwd` fields.
- Updated core exec, unified exec, debug-sandbox, TUI setup/grant flows,
and app-server setup to pass the actual effective `PermissionProfile`.
- Left regression coverage asserting the old IPC policy fields are
absent and the runner serializes tagged `PermissionProfile` JSON.

## Verification

- `cargo test -p codex-windows-sandbox`
- `cargo test -p codex-core windows_sandbox`
- `cargo test -p codex-app-server
request_processors::windows_sandbox_processor`
- `just fix -p codex-windows-sandbox -p codex-core -p codex-app-server
-p codex-cli -p codex-tui`
- `just fix -p codex-cli -p codex-tui`
- `just fix -p codex-windows-sandbox -p codex-tui`
- `rg "\\bSandboxPolicy\\b" codex-rs/windows-sandbox-rs` returned no
matches.

Note: `cargo test -p codex-cli` was attempted but did not reach crate
tests because local disk filled while compiling dependencies (`No space
left on device`). The targeted clippy pass compiled the affected CLI/TUI
surfaces afterward.

Michael Bolin c9ff067e31 windows-sandbox: add profile-native elevated APIs (#23714) 
## Why

This is the next step after #23167 in the Windows sandbox
`PermissionProfile` migration. The elevated Windows backend still
exposed policy-string entry points, which forced callers to pass a
compatibility `SandboxPolicy` before the command-runner IPC could
receive a profile.

Adding profile-native APIs first keeps the core switch in the next PR
small: reviewers can see that the Windows crate can prepare elevated
setup, capability SIDs, and runner IPC from a resolved
`PermissionProfile` without changing core behavior yet.

## What

- Adds `ElevatedSandboxProfileCaptureRequest` and
`run_windows_sandbox_capture_for_permission_profile_elevated` for
one-shot elevated capture.
- Adds `spawn_windows_sandbox_session_elevated_for_permission_profile`
for unified exec sessions.
- Factors elevated spawn prep through
`prepare_elevated_spawn_context_for_permissions`, so both new APIs
operate from `ResolvedWindowsSandboxPermissions` directly.
- Keeps the existing legacy policy-string APIs as adapters for callers
that have not moved yet.

## Verification

- `cargo test -p codex-windows-sandbox`

Michael Bolin 896ee672cc windows-sandbox: feed setup from resolved permissions (#23167) 
## Why

This is the next step in the Windows sandbox migration away from the
legacy `SandboxPolicy` abstraction. #22923 moved write-root and token
decisions onto `ResolvedWindowsSandboxPermissions`, but setup and
identity still accepted `SandboxPolicy` and converted internally. This
PR pushes that conversion outward so the setup path consumes the
resolved Windows permission view directly.

## What Changed

- Changed `SandboxSetupRequest` to carry
`ResolvedWindowsSandboxPermissions` instead of `SandboxPolicy` plus
policy cwd.
- Updated setup refresh/elevation and identity credential preparation to
use resolved permissions for read roots, write roots, network identity,
and deny-write payload planning.
- Removed the production `allow.rs` legacy wrapper; allow-path
computation now takes resolved permissions directly.
- Added a permissions-based world-writable audit entry point while
keeping the existing legacy wrapper for compatibility.
- Updated legacy ACL setup and the core Windows setup bridge to
construct resolved permissions at the boundary.
- Hardened the Windows sandbox integration test helper staging so Bazel
retries can reuse an already-staged helper if a prior sandbox helper
process still has the executable open.

## Verification

- `cargo test -p codex-windows-sandbox`
- `cargo test -p codex-core --test all --no-run`
- `just fix -p codex-windows-sandbox`
- `just fix -p codex-core`
- Attempted `cargo check -p codex-windows-sandbox --target
x86_64-pc-windows-gnullvm`, but the local machine is missing
`x86_64-w64-mingw32-clang`; Windows CI should cover that target.

Michael Bolin e1ec0eee5f windows-sandbox: drive write roots from resolved permissions (#22923) 
## Why

This is the third PR in the Windows sandbox `SandboxPolicy` ->
`PermissionProfile` migration stack.

#22896 introduced `ResolvedWindowsSandboxPermissions`, and #22918 moved
elevated runner IPC to carry `PermissionProfile`. This PR starts moving
the remaining setup/spawn helpers away from asking legacy enum questions
like “is this `WorkspaceWrite`?” and toward resolved runtime permission
questions like “does this profile require write capability roots?”

## What changed

- Added resolved-permissions helpers for network identity and
write-capability detection.
- Moved setup write-root gathering to operate on
`ResolvedWindowsSandboxPermissions`, with the legacy `SandboxPolicy`
wrapper left in place for existing call sites.
- Updated identity setup, elevated capture setup, and world-writable
audit denies to use resolved write roots.
- Updated spawn preparation to carry resolved permissions in
`SpawnContext` and use them for network blocking, setup write roots,
elevated capability SID selection, and legacy capability roots.
- Removed a now-unused legacy write-root helper.

## Verification

- `cargo test -p codex-windows-sandbox`
- `just fix -p codex-windows-sandbox`
- Existing stack checks are green on #22896 and #22918; CI has started
for this PR.

Michael Bolin 729bdf3c8d windows-sandbox: send permission profiles to elevated runner (#22918) 
## Why

This is the next PR in the Windows sandbox migration stack after #22896.
The bottom PR introduces a Windows-local resolved permissions helper
while existing callers still start from legacy `SandboxPolicy`. This PR
moves the elevated runner IPC boundary to `PermissionProfile`, which
makes the direction of the stack visible without changing the public
core call sites yet.

Because that changes the CLI-to-command-runner message shape, the framed
IPC protocol version is bumped in the same PR so the boundary change is
explicit.

## What changed

- Replaced elevated IPC `policy_json_or_preset`/`sandbox_policy_cwd`
fields with `permission_profile`/`permission_profile_cwd`.
- Bumped the elevated command-runner IPC protocol to
`IPC_PROTOCOL_VERSION = 2` and switched parent/runner frames to use the
shared constant.
- Converted the parent elevated paths from the parsed legacy policy into
a materialized `PermissionProfile` before sending the runner request.
- Added `WindowsSandboxTokenMode` resolution for managed
`PermissionProfile` values and made the runner choose read-only vs
writable-root capability tokens from that resolved profile.
- Rejected disabled, external, unrestricted, and full-disk-write
profiles before token selection.
- Added IPC JSON coverage for tagged `PermissionProfile` payloads and
token-mode unit coverage for the resolved permission helper.

## Verification

- `cargo test -p codex-windows-sandbox`
- `just fix -p codex-windows-sandbox`
- `cargo check -p codex-windows-sandbox --target x86_64-pc-windows-msvc
--tests` was attempted locally but blocked before crate type-checking
because the macOS compiler environment lacks Windows C headers such as
`windows.h` and `assert.h`; GitHub Windows CI is the required
verification for the runner path.

Michael Bolin 2b4898cc47 windows-sandbox: add resolved permissions helper (#22896) 
## Why

The Windows sandbox migration away from the legacy `SandboxPolicy`
abstraction needs a small local bridge before IPC and core wiring can
move to `PermissionProfile`. Leaf helpers currently branch directly on
`WorkspaceWrite`, which spreads legacy assumptions through path planning
and token setup code.

This PR introduces a Windows-local resolved permissions view so those
helpers can ask Windows-specific questions about runtime
filesystem/network permissions without matching on the legacy policy
enum everywhere.

## What changed

- Added `ResolvedWindowsSandboxPermissions` in
`windows-sandbox-rs/src/resolved_permissions.rs`, with legacy
`SandboxPolicy` constructors for the current call sites.
- Moved `allow.rs` writable-root and read-only-subpath planning onto the
resolved permissions type.
- Preserved Windows `TEMP`/`TMP` writable-root behavior when the
effective policy includes writable tmpdir access.
- Avoided resolving Unix `:slash_tmp` or parent-process `TMPDIR` while
computing Windows writable roots.
- Reused the shared allow-path result for setup write-root gathering and
routed network-block selection through the resolved abstraction.

## Verification

- `cargo test -p codex-windows-sandbox`
- `just fix -p codex-windows-sandbox`
- GitHub CI restarted on the amended commit; Windows Bazel is the
required signal for the Windows-only code paths.
