* refactor(ocsf): attribute events to session-bound contexts A supervisor process that hosts several sandboxes cannot use one process-wide OCSF context: every event would carry the wrong sandbox identity, and middleware requests read their sandbox identity from the same context. Builders now accept a ContextRef, either a borrowed context or a context shared by a hosted session, so per-session contexts need not be leaked. ctx() returns the context bound to the calling thread when present and falls back to the process-wide context otherwise. OCSF JSON output settings can likewise be bound per thread, and OpenTelemetry can parent a span from an explicit W3C trace context instead of process environment. A dedicated supervisor keeps using the process-wide context.

A second sandbox in the same process would have replaced or rotated the first sandbox's credentials, reused its provider access tokens, and exposed its denials through policy.local. GatewayCredentials now holds one session's gateway and Sandbox Protocol credentials and their renewal; every gateway client receives a GatewayEndpoint that pairs the URL with them, including log push, ConnectSupervisor and its redirects, and extension-credential rotation. run_networking takes a NetworkSession with the sandbox identity, the session's gateway access, its Workload API socket, its policy.local denial source, and its proxy CA files. Provider token grants use a cache and HTTP client owned by the session and fail closed without a Workload API socket. run_session supervises one generation from an explicit SessionConfig and owner-provided SessionControls. run_sandbox_with_backend remains the dedicated entry point: it keeps the process-wide OCSF context, reads the same environment, binds readiness endpoints to session readiness, and stops on SIGTERM or SIGINT. The binary shares one set of credentials between log push and supervision, as before. Signed-off-by: Drew Newberry <anewberry@nvidia.com> * feat(supervisor): host concurrent sessions on session-bound runtimes SessionHost runs several supervisor sessions in one process. Each session gets its own Tokio runtime, and every thread that runtime starts, plus the thread driving it, is bound to the session's OCSF context, OCSF JSON settings, log sink, and denial log. Tasks, blocking work, reconnects, and credential renewal spawned by a session therefore keep its identity, while threads outside any session carry none and push no logs. Gateway credentials stay explicit per session. Removing a session stops its workload gracefully, or cancels it at once while it is still starting, then shuts down only its runtime and revokes its gateway credentials. The key stays registered until the session thread has finished, so the same generation cannot gain a second owner while one is stopping. A panicking session reports a failure, clears its readiness, and is revoked the same way. Hosted sessions get a private proxy trust directory and serve policy.local denials from their own log. A focused test runs two sessions concurrently and checks that nested and blocking tasks see their own identity, gateway requests carry their own bearer, log lines reach only their own stream, and removing one leaves the other supervising. Closes #4699 Signed-off-by: Drew Newberry <anewberry@nvidia.com> * refactor(supervisor): name hosted lifetimes sandbox instances A sandbox instance is one running generation of a stable Sandbox resource. Gateway transport connections and the gateway supervisor sessions they carry can reconnect within one instance, so the hosted object, its configuration, controls, host, and per-instance network, denial, and token-grant state now use the sandbox instance name. Rename session_host to sandbox_instance_host, run_session to run_sandbox_instance, and SessionConfig, SessionControls, SessionHost, and related hosted types to their SandboxInstance equivalents. Gateway supervisor sessions, SSH sessions, and authentication session types keep their names. No wire, configuration, or lifecycle behavior changes. Signed-off-by: Drew Newberry <anewberry@nvidia.com> * refactor(supervisor): launch sandbox instances from one config and prepared bindings Replace SandboxRunConfig and its field-by-field copy into SandboxInstanceConfig with a single launch configuration. Live per-instance state (gateway credentials, OCSF context and JSON settings, log sink, and denial log) is now an explicit SandboxInstanceBindings value that the owner prepares once, instead of placeholders the runner or host overwrote. The dedicated binary loads launch inputs from its arguments and environment and shares one GatewayCredentials with log push; run_sandbox_with_backend keeps the process-wide OCSF context, health endpoints, and signal handling. The instance host binds the same SandboxInstanceBindings to its runtime threads and revokes their credentials when the instance ends.

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.
