* fix(isolation): validate Unix socket paths the same way on every host Prior to this change, SandboxTransport::validate checked Unix socket paths with Path::is_absolute(). On Windows that requires a drive or UNC prefix, so a POSIX path such as /run/backend.sock was rejected as "invalid boundary control transport endpoint". The isolation backend registration work in #3898 added tests that register Unix endpoints in the core registration types, gateway config, gateway config preflight, and supervisor backend setup; all of them failed on the Windows MSVC runners. The Windows test job only runs on PRs labeled test:windows, so the break went unnoticed on main. Unix transport is refused at runtime on non-Unix hosts, so these paths are always POSIX paths regardless of where they are validated. Now, both the core registration validator and the sandbox backend protocol validator use a new openshell_core::paths::is_posix_absolute helper, which applies the POSIX rule (the path starts with '/') on every host. On Unix this matches is_absolute() exactly.

Enrichment only adds paths that exist on the host. Prior to this change, the tests assumed those paths exist, so on Windows enrichment added nothing, the precondition assertions failed, and the baseline case of permanent_codes_still_exit never saw a write to refuse. Now, the four baseline write-back tests are gated to Unix, and permanent_codes_still_exit checks the image policy upload case on every host and the baseline write-back case only on Unix. Signed-off-by: Kris Hicks <khicks@nvidia.com> * test(server): scale the SQLite concurrent-write test for Windows fsync sqlite_concurrent_writes_return_their_own_resource_version (#4408) runs 8 writers that each make 25 unconditional and 25 version-checked writes against one row of an on-disk WAL database with synchronous=FULL. Writers serialize on the SQLite write lock and wait out sqlx's default 5s busy_timeout. Prior to this change, the per-commit fsync cost on the Windows runners was high enough that a waiting writer starved past that timeout and failed with "database is locked" after about 7s. Now, each writer makes 5 writes on Windows and 25 elsewhere. The test still races every writer on the same row, which is what it checks. Signed-off-by: Kris Hicks <khicks@nvidia.com> * test(server): hold scope-mix locks for wall-clock time, not timer ticks random_scope_mix_never_deadlocks (#4147) runs 64 tasks of 50 random lock operations and holds each operation's locks for 0-2 ms, failing if the mix does not finish within 20s. Prior to this change, the hold was a tokio::time::sleep. Windows timers round a 1 ms sleep up to about 16 ms, and a quarter of the operations take the exclusive global lock, so the serialized holds alone took several seconds and the full mix exceeded the 20s deadline on the Windows runners. Now, occupy yields until a std::time::Instant deadline, so holds last 0-2 ms of wall-clock time on every platform and the deadline means the same thing everywhere. Signed-off-by: Kris Hicks <khicks@nvidia.com> * test(supervisor): run sandbox instance host tests only on Unix hosts The sandbox_instance_host tests added with per-instance supervisor state (#4701) admit hosted instances through SandboxInstanceHost::new, which prepares a private directory per instance. Hosted sandbox instances are Unix-only: on other hosts prepare_private_dir returns "hosted sandbox instances require a Unix host". Prior to this change, the test module still compiled and ran on Windows, so all three tests failed while creating their host. Now, the test module is gated to Unix, and the Unix-only permission check inside one test no longer needs its own cfg attribute.

openshell-core
Shared types, constants, configuration, and helpers used across OpenShell crates.
Isolation registrations
isolation_registration owns the operator registry's backend names, byte-stream
endpoints, and shared validation. Its fallible conversions carry registrations
through the compute-driver protobuf and back into the supervisor's JSON launch
file. These routes contain no credentials or driver-owned launch coordinates.
Object Metadata
Top-level user-facing objects use a Kubernetes-style metadata convention. The metadata shape provides:
- Stable server-generated ID.
- Human-readable name.
- Creation timestamp.
- Optional labels for filtering and automation.
Code that works with object metadata should use the traits in
openshell_core::metadata instead of reaching into protobuf fields directly:
use openshell_core::{ObjectId, ObjectLabels, ObjectName};
let id = sandbox.object_id();
let name = sandbox.object_name();
let labels = sandbox.object_labels();
Trait methods must tolerate missing metadata and return safe empty values rather than panicking.
Label Rules
Labels follow Kubernetes-style key and value conventions:
- Keys may include an optional DNS-prefix followed by
/. - Names are limited to alphanumeric characters plus
-,_, and.. - Values use the same character set and may be empty.
- Selectors use comma-separated
key=valuepairs with AND semantics.
Validate labels at API ingress before persisting objects.
Inference Profiles
Provider inference profiles live in this crate so the gateway, sandbox, and router agree on provider defaults. Profiles define:
- Auth header style.
- Default upstream headers.
- Client-supplied passthrough headers.
- Supported inference protocol shapes.
Do not duplicate provider-specific inference behavior in callers. Add shared behavior here, then consume it from the gateway, sandbox, and router.
Middleware Contracts
Built-in supervisor middleware identifiers, host-selector matching, and pure
configuration validation live in openshell_core::middleware. Policy admission
and the supervisor runtime consume the same contract without introducing a
dependency from the policy crate to the supervisor implementation.
Protobuf Struct Conversion
Use openshell_core::proto_struct when crossing between serde_json values and
prost_types::{Struct, Value}. Both conversion directions live in this module;
JSON-to-protobuf conversion is fallible so callers cannot silently replace an
unrepresentable number.
