* fix(cli): backpressure sandbox uploads Stream archive uploads over a bounded SSH subsystem whose credit follows extraction stdin progress. Preserve the existing input budget and tar destination semantics, validate completion, and clean up cancelled transfers. Add protocol, lifecycle, and large-upload regression coverage without changing russh. Signed-off-by: Shiju <shiju@nvidia.com> * fix(cli): preserve upload cancellation and errors Keep cancellation active through upload setup and retry delays, and terminate cancelled SSH probes. Preserve protocol failures through output completion and report captured diagnostics on early extraction failure. Remove redundant upload validation and extend the affected regressions. Signed-off-by: Shiju <shiju@nvidia.com> * refactor(cli): carry upload credit over SSH streams Replace the framed upload protocol with SSH's own streams. The client sends one JSON plan line, the raw archive and EOF. The supervisor's stdout carries only cumulative totals of bytes written to extraction stdin, extraction output goes to stderr, and the exit status reports the result. Extraction starts inline through the ordinary exec path. This removes the frame codec, SHA-256 digests, the CLI sha2 dependency and the supervisor upload state machine while keeping the 1 MiB credit window, the 4 MiB input guard, cancellation and error reporting. A failed archive now stops SSH before closing stdin, so EOF never marks a truncated archive complete. Signed-off-by: Shiju <shiju@nvidia.com> * fix(cli): isolate upload SSH connections and pin credit cadence - Apply the forward multiplexing overrides to the upload ssh command, so a user ControlMaster cannot carry an upload over another session's master connection. - Kill ssh before closing its stdin when a transfer fails locally, and include ssh stderr in transport errors. - Share ACK_INTERVAL_BYTES from core. Assert at compile time that CLI chunks fit the credit left after an ack and that the window stays below the supervisor's pending-input guard. - Log the real reason when the supervisor rejects an upload. - Test that a single-packet upload reports its final total.

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.
