* fix(driver-podman): resolve Podman socket via auto-detection Align Podman socket selection with the existing Docker model: explicit config wins, otherwise probe openshell-core for a responsive socket. This also fixes the original HOME-unset panic, since resolution no longer hardcodes a per-OS default path. - add detect_podman_socket() in openshell-core, mirroring detect_docker_socket - PodmanComputeConfig.socket_path is now Option<PathBuf>, no default - remove default_socket_path() (podman driver) and podman_socket_path() (vm driver), both replaced by the shared detector - update server env override and CLI for the new Option type - add tests: responsive-candidate detection in openshell-core, and config-error (not panic) when no socket is configured or reachable * fix(driver-podman): address review feedback on socket resolution Extract socket resolution into resolve_socket_path, taking the detector as a parameter so tests do not depend on real env vars or the host's actual Podman state. Replace the flaky env-mutating test with three deterministic cases: explicit wins, detected is used when absent, and neither source errors. Fix the socket_path doc comment to describe it from a config user's point of view, matching DockerComputeConfig's docstring. Drop a comment that only made sense next to the Docker driver code. Update the Podman README and gateway docs: they described a fixed per-OS default path that no longer exists, replace with the actual probe-then-fail behavior. * docs(driver-podman): simplify socket default description Previous wording was self-contradictory (says auto-detect on unset, then lists the same var as a probed candidate) and omitted the Linux /run/user/uid/podman/podman.sock candidate.
openshell-core
Shared types, constants, configuration, and helpers used across OpenShell crates.
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.
