…VIDIA#2271) * feat(sdk/go): add Go SDK foundation, types, and sandbox client (A) Add the Go SDK module with the full API contract and a working sandbox client as the first vertical slice. All other resource clients are present as stubs returning Unimplemented errors, to be replaced with real implementations in subsequent PRs. Contents: - Module setup (go.mod, Makefile, mise.toml) - All domain types (types/ package) - Full ClientInterface with all sub-client accessors - Shared infrastructure (errors, auth, gRPC connection, logging) - Sandbox client with converter and tests (fully functional) - Stub clients for remaining resources (exec, file, health, provider, profile, config, refresh, policy, service, ssh, tcp) Part of the Go SDK decomposition plan (NVIDIA#2270). Implements NVIDIA#2044. * fix(sdk/go): address review feedback on PR NVIDIA#2271 - Make scheme parsing drive transport selection: http:// uses plaintext gRPC, https:// or no scheme uses TLS. Add regression tests. - Add Resources and DriverConfig fields to SandboxTemplate and update both converter directions (SandboxFromProto/SandboxSpecToProto). - Regenerate proto bindings from current canonical proto sources to eliminate drift (SigV4/MCP fields, params matchers, reserved fields). - Run gofmt/goimports on all handwritten Go files. Signed-off-by: Roland Huß <rhuss@redhat.com> * fix(sdk/go): address principal engineer review findings - Remove dead boolCount function that would fail golangci-lint (#1) - Emit EventAdded for the first watch event instead of EventModified, matching k8s watch semantics (#7) - Add mutex locking to all mock server methods that access the shared sandboxes map, fixing latent race conditions (NVIDIA#12) - Skip HealthCheck integration test that calls an unimplemented stub (NVIDIA#13) - Scope doc.go examples: mark sections for sub-clients not yet available in this PR with "available in a future release" (#4) - Document Config.Timeout/RetryPolicy/Logger and WatchOptions fields as reserved for future use (#2, #6) Signed-off-by: Roland Huß <rhuss@redhat.com> * refactor(sdk/go): migrate mise config to centralized task include Move Go SDK mise configuration from standalone sdk/go/mise.toml into the project's centralized pattern: - Add Go tools (go, golangci-lint, protoc-gen-go, protoc-gen-go-grpc) to root mise.toml [tools] section - Create tasks/go.toml with all SDK tasks using go: namespace prefix and dir=sdk/go for working directory - Update sdk/go/Makefile to reference namespaced task names - Update proto:sync default path for monorepo layout Addresses review feedback from drew on PR NVIDIA#2271 regarding mise convention alignment. Signed-off-by: Roland Huß <rhuss@redhat.com> * refactor(sdk/go): remove UPSTREAM_VERSION standalone repo artifact Remove sdk/go/proto/UPSTREAM_VERSION file and its exclusion from proto:check. This was a leftover from the standalone repo prototype. In a monorepo, proto drift is detectable via git diff between sdk/go/proto/ and proto/ directly. Signed-off-by: Roland Huß <rhuss@redhat.com> * refactor(sdk/go): switch proto generation from protoc to buf Replace raw protoc invocations with buf for Go SDK proto code generation, aligning with the TS SDK approach (PR NVIDIA#2122). - Add repo-level buf.yaml declaring proto/ as the buf module with lint and breaking change detection config - Add sdk/go/buf.gen.yaml configuring buf to generate Go code directly from root proto/ (no more vendored .proto copies) - Delete vendored .proto source files from sdk/go/proto/ - Rewrite go:proto:gen and go:proto:check mise tasks to use buf - Remove go:proto:sync and go:proto:clean tasks (no longer needed) - Add proto target to sdk/go/Makefile - Add buf 1.72.0 to root mise.toml tool dependencies - Include options.proto in generation (was stripped from vendored copies) - Regenerate all .pb.go files via the new buf pipeline Signed-off-by: Roland Huß <rhuss@redhat.com> * test(sdk/go): add proto-converter field coverage detection Use protobuf reflection to enumerate all fields on key proto messages (SandboxSpec, SandboxTemplate, SandboxStatus, SandboxCondition, SandboxPolicy) and compare against explicit handled/skipped sets in the converter tests. Unhandled fields produce warnings (t.Log), not failures, so proto contributors are not forced to fix SDK converters in the same PR. Stale entries in the handled set (removed proto fields) do fail, since they indicate the converter references something that no longer exists. A follow-up CI workflow will create GitHub issues when converter drift lands on main. Signed-off-by: Roland Huß <rhuss@redhat.com> * fix(sdk/go): bump Go to 1.26 and fix errcheck lint violations The upstream go.mod now has `toolchain go1.26.4`, which requires Go 1.26 to build golangci-lint. Bump the mise.toml Go version from 1.25 to 1.26 and wrap deferred Close() calls in test helpers to satisfy errcheck. Assisted-By: 🤖 Claude Code * feat(sdk/go): add ObjectMeta fields (annotations, workspace, deletion_timestamp) Add three new proto ObjectMeta fields to Sandbox and Provider domain types: Annotations (map), Workspace (string), and DeletionTimestamp (*time.Time). Update converters in both directions, deep-copy maps at the proto/SDK boundary, and add TimeFromMillisPtr/MillisFromTimePtr helper functions. Assisted-By: 🤖 Claude Code * chore(sdk/go): regenerate proto bindings after rebase Pick up workspace fields from upstream PR NVIDIA#2445 (Wire authorization into workspace model). All request messages now include workspace parameter in the generated Go bindings. Assisted-By: 🤖 Claude Code * feat(sdk/go): add workspace scoping to all RPC interfaces Add workspace parameter to every sandbox-scoped RPC method across all interfaces (Sandbox, Exec, File, Service, SSH, TCP, Config, Policy, Provider, Profile, Refresh). The workspace string is passed as the second parameter after ctx, following the convention workspace then resource-name. Key changes: - SandboxInterface: all 10 methods gain workspace parameter - sandbox_client.go: passes Workspace field in every proto request - ListOptions: add AllWorkspaces field for cross-workspace queries - All stub interfaces updated to match new signatures - All sandbox client tests updated with "default" workspace Assisted-By: 🤖 Claude Code * chore(sdk/go): remove coverage.out from tracking Assisted-By: 🤖 Claude Code * fix(sdk/go): address review feedback from mrunalp - Add RefreshStrategyAWSStsAssumeRole to match proto enum value 6, fulfilling the "all domain types upfront" contract - Wrap context.DeadlineExceeded and context.Canceled in StatusError so IsDeadlineExceeded() and IsCancelled() helpers work correctly - Return error from mapToStruct/SandboxSpecToProto instead of silently discarding structpb.NewStruct failures on invalid template maps Signed-off-by: Roland Huss <rhuss@redhat.com> * fix(sdk/go): address remaining review items - Wire go:ci into root ci task so SDK is tested in repository CI - Fix gofmt formatting on converter files - Add goimports to mise.toml tools - Add coverage.out to .gitignore - Add Go SDK section to AGENTS.md and CONTRIBUTING.md - Add regression tests for context-error wrapping (IsDeadlineExceeded, IsCancelled) and invalid template map rejection - Remove panic from SandboxToProto, return error instead Signed-off-by: Roland Huss <rhuss@redhat.com> * fix(sdk/go): pin goimports version and update lockfile Pin goimports to 0.48.0 instead of "latest" and regenerate mise.lock to include the new entry. Signed-off-by: Roland Huss <rhuss@redhat.com> * fix(sdk/go): TLS.Insecure means skip-verify, not plaintext Align TLS.Insecure semantics with the Rust SDK: Insecure: true now uses TLS with InsecureSkipVerify (skip cert verification) instead of switching to plaintext. Only the http:// scheme triggers plaintext. This fixes token auth against dev/k3d gateways: StaticToken and RefreshableToken require transport security, which real TLS (even with InsecureSkipVerify) satisfies, but plaintext does not. For http:// + token auth (dev gateways without TLS), wrap the auth provider to override RequireTransportSecurity, matching the Rust SDK's behavior where http:// accepts any auth mode. Transport decision table (matches Rust SDK crates/openshell-sdk): http:// + any TLS config -> plaintext (TLS config ignored) https:// + Insecure: true -> TLS, skip cert verify https:// + Insecure: false -> TLS, full verification no scheme -> same as https:// Signed-off-by: Roland Huss <rhuss@redhat.com> * feat(sdk/go): add missing policy proto fields Add 6 previously silently dropped fields to the network policy types and converters, preventing security-relevant data loss on round-trip: NetworkEndpoint fields 19-23: - CredentialSigning: SigV4 re-signing mode - SigningService: AWS service name for SigV4 - SigningRegion: AWS region override for SigV4 - JsonRpcMaxBodyBytes: JSON-RPC body inspection limit - Mcp: MCP-specific policy options (new McpOptions type) L7Allow and L7DenyRule field 9: - Params: MCP params matcher map for tools/call filtering New type McpOptions with StrictToolNames and AllowAllKnownMcpMethods optional booleans matching the proto definitions. Signed-off-by: Roland Huss <rhuss@redhat.com> * fix(sdk/go): enforce coverage test and extend to policy messages Change coverage_test.go from t.Logf (silent) to t.Errorf so that unhandled proto fields fail the test immediately. Add coverage tests for NetworkEndpoint (23 fields), L7Allow (8 fields), L7DenyRule (8 fields), and McpOptions (2 fields). Any new proto field that is not in the handled set or explicitly skipped now breaks the build, closing the silent-drift gap. Signed-off-by: Roland Huss <rhuss@redhat.com> * ci(sdk/go): add Go SDK job to branch-checks workflow Add a Go SDK job to branch-checks.yml that runs mise run go:ci (lint, build, test, proto-check, docs-check) on every PR. This ensures the SDK is tested in CI, not just locally. Signed-off-by: Roland Huss <rhuss@redhat.com> * fix(sdk/go): address should-fix review items #6 Fix broken godoc examples: add workspace parameter to all method calls in doc.go that were broken after workspace scoping. #7 Add Err field to Event[T]: Watch error events now carry the underlying error instead of discarding it. #8 Separate Unauthenticated from PermissionDenied: add ErrorUnauthenticated code and IsUnauthenticated() helper. gRPC Unauthenticated (401) now maps to its own code instead of collapsing into PermissionDenied (403). #9 Add Unwrap to StatusError: replace dead Details field with Cause error field. StatusError.Unwrap() returns Cause, enabling errors.Is/As unwrapping. FromGRPCError and contextError both populate Cause. Signed-off-by: Roland Huss <rhuss@redhat.com> * ci(sdk/go): add go:format:check to CI pipeline Add gofmt format verification to go:ci. Catches unformatted Go files before they reach the PR. Fix formatting on coverage_test.go. Signed-off-by: Roland Huss <rhuss@redhat.com> * chore(sdk/go): remove Makefile in favor of mise tasks All build, lint, test, and proto-gen tasks are already defined in tasks/go.toml and invoked via mise. The Makefile was a leftover that duplicated this and raised questions in review. Signed-off-by: Roland Huß <rhuss@redhat.com> * feat(sdk/go): sync proto bindings and add credential handle support Regenerate Go proto bindings after rebase to pick up new CredentialHandle message and Provider.credential_handles and profile_workspace fields from upstream. Add domain types, converter support, and proto field coverage tests for Provider and CredentialHandle. Signed-off-by: Roland Huß <rhuss@redhat.com> * fix(sdk/go): reject plaintext auth leak and fix watch error handling Reject http:// addresses when the auth provider requires transport security instead of silently stripping the requirement. Remove the insecureAuthWrapper that overrode RequireTransportSecurity. Fix watch stream error handling: use blocking send for terminal errors so they are never silently dropped when the channel is full, and wrap mid-stream errors with converter.FromGRPCError so SDK error helpers like IsUnavailable work on watch Event.Err. Signed-off-by: Roland Huß <rhuss@redhat.com> * fix(sdk/go): address review findings from multi-agent code review - WaitReady now detects SandboxDeleting phase and returns immediately instead of polling indefinitely - Watch goroutine defers streamCancel() to prevent context leaks - Fix StopOnTerminal=false test to keep stream open (was wrong-reason pass due to stream ending, not StopOnTerminal logic) - Add EventDeleted test covering the Deleting phase branch - Add provider converter unit tests for CredentialHandle round-trip, nil handling, and empty maps Signed-off-by: Roland Huß <rhuss@redhat.com> --------- Signed-off-by: Roland Huß <rhuss@redhat.com> Signed-off-by: Roland Huss <rhuss@redhat.com>

…NVIDIA#2795) * feat(cli): support OIDC device authorization grant for headless login ClosesNVIDIA#2793 Add OAuth 2.0 Device Authorization Grant (RFC 8628) support to the OpenShell CLI's OIDC login flow. When running in a headless environment (OPENSHELL_NO_BROWSER=1) without a client secret configured, the CLI now uses the device code flow instead of the browser-based PKCE flow. The device code flow: - Requests a device code and user code from the IdP's device authorization endpoint - Displays a verification URL and user code to the user - Polls the token endpoint until the user completes authorization or the code expires - Supports slow_down responses per RFC 8628 by increasing the polling interval This implementation: - Extends OidcDiscovery to optionally capture device_authorization_endpoint - Adds oidc_device_code_flow function with proper error handling for all RFC 8628 error codes - Updates gateway add and gateway login to dispatch to device flow when browser is suppressed - Adds comprehensive unit tests for device flow structs and response parsing - Updates gateway authentication documentation to describe the device code fallback Signed-off-by: Jesse Jaggars <jjaggars@redhat.com> * fix(cli): validate OIDC device token responses Signed-off-by: Jesse Jaggars <jjaggars@redhat.com> * fix(cli): add PKCE to OIDC device flow Signed-off-by: Jesse Jaggars <jjaggars@redhat.com> * docs(cli): document PKCE device flow Signed-off-by: Jesse Jaggars <jjaggars@redhat.com> --------- Signed-off-by: Jesse Jaggars <jjaggars@redhat.com>

Inline comments:
In `@architecture/gateway.md`:
- Line 177: Update the OIDC entry in the authentication table to describe
browser and device-code PKCE as user authentication, while identifying client
credentials as unattended automation authentication; do not group all three
modes under “auth for users.”
In `@crates/openshell-cli/src/commands/gateway.rs`:
- Around line 908-927: Update the authentication state handling around
oidc_device_code_flow so auth_skipped represents only branches where
authentication was genuinely skipped, not all browser-suppressed flows. Mark the
device-code attempt as not skipped even when it fails, ensuring the existing
rollback_gateway_registration path removes failed registrations while preserving
registrations for actual authentication skips.
In `@crates/openshell-cli/src/oidc_auth.rs`:
- Around line 348-353: Update the device authorization POST and polling requests
in the device-flow logic to apply a finite per-request timeout, including the
calls around device_auth_resp and the subsequent poll request. Reuse the
existing timeout configuration or define an appropriate duration so each send
returns within a bounded interval and the expiry check can run.
- Around line 331-335: Update the scopes_param construction in the build_scopes
flow to map each scope with s.as_ref() instead of s.to_string(), preserving the
existing space-separated collection and join behavior.
In `@crates/openshell-policy/src/merge.rs`:
- Line 1285: Update endpoint_attributes_cover and all additive-flag coverage
checks to compare allow_uninspected_credentials, preserving false-to-true as
uncovered. Add a test covering a partial-binary update that enables this flag
and assert it returns ExistingBinariesWouldInheritAuthorization.
In `@crates/openshell-providers/src/profiles.rs`:
- Around line 2217-2236: Restrict the validation block around
profile.has_credentialed_endpoints() so the L4 or tls: skip requirement applies
only when the current endpoint has credential_signing, while retaining
profile-wide credential declaration handling. Add a mixed-endpoint test covering
one SigV4 endpoint and one unrelated L4 endpoint, ensuring the unrelated
endpoint does not require allow_uninspected_credentials; apply the same scoping
in the corresponding validation logic near the other reported occurrence.
In `@crates/openshell-sandbox/src/lib.rs`:
- Around line 335-341: Update the policy poll loop’s successful provider
credential installation path to re-evaluate credential_gating_unavailable using
the refreshed resolver state and network_enabled, and report only on a
false-to-true transition after startup. Reuse the existing
report_credential_gating_unavailable behavior and add a regression test covering
credentials unavailable at startup followed by successful refresh for a
LocalOverride sandbox.
In `@crates/openshell-server/src/grpc/sandbox.rs`:
- Around line 584-590: Update validate_candidate_provider_attachments to resolve
the policy baseline with current_base_policy_for_sandbox, matching the existing
validation path, and pass that resolved live policy to
validate_candidate_sandbox_credential_policy instead of candidate_spec.policy.
In `@crates/openshell-supervisor-network/src/l7/websocket.rs`:
- Around line 1199-1208: Re-check the transformed WebSocket text after
middleware processing and, when deny_uninspected_credentials is enabled with no
resolver and contains_reserved_credential_marker detects a marker, emit
emit_uninspected_credential_denial with the websocket-text context and return
PolicyDenial via terminate instead of MiddlewareFailure. Add a test covering
middleware introducing a reserved marker when no resolver is available.
In `@crates/openshell-supervisor-network/src/opa.rs`:
- Around line 855-879: Update query_endpoint_credential_guards to call the
test-only record_test_opa_query counter like the other per-request query
methods, and replace the direct set_input_json conversion with the shared
set_regorus_input helper. Preserve the existing engine locking, rule evaluation,
and result handling.
In `@crates/openshell-supervisor-network/src/proxy.rs`:
- Line 4584: Update the initialization of deny_uninspected_credentials in the
request handling flow to use endpoint_credentials_for_request(...).resolver
rather than the connection-level secret_resolver, and enable it for
provider-credentialed endpoints when decision.endpoint.l7_route is absent or
empty. Preserve the existing behavior for routed endpoints while ensuring
forward requests without an L7 route undergo body marker scanning.
In `@docs/kubernetes/ingress.mdx`:
- Line 94: Update the headless interactive-login instruction to include both
`openshell gateway add` and `openshell gateway login`, clarifying that the
device authorization flow applies when no client secret is configured. Preserve
the existing unattended client-credentials guidance and browser-based default
behavior.
In `@docs/reference/gateway-auth.mdx`:
- Around line 123-128: Update the opening OIDC gateway flow description to state
that Authorization Code with PKCE is the default flow, while preserving the
existing device authorization and client credentials alternatives.
In `@e2e/rust/tests/credential_gating.rs`:
- Around line 653-710: Replace the listed assert! failure checks in
assert_gateway_admission, assert_rest_body_backstop, and
assert_websocket_binary_denied with Result-compatible Err returns, preserving
each existing failure message and success behavior so
credentialed_endpoint_gates_work_end_to_end can unwind normally and run provider
cleanup.

Outside diff comments:
In `@crates/openshell-cli/src/commands/gateway.rs`:
- Around line 1140-1160: Update the device-code branch in the login flow to
honor force_fresh_login by forwarding it to oidc_device_code_flow so the
authorization request uses prompt=login; otherwise preserve the marker until a
flow that supports fresh login can consume it. Keep the existing browser
behavior and marker-clearing behavior unchanged when fresh-login enforcement has
been applied.
In `@crates/openshell-supervisor-network/src/l7/relay.rs`:
- Around line 1196-1257: The WebSocket credential-denial guard must also cover
upgrades with a bound secret resolver when provider credentials are not
configured. Update upgrade_options to use
config.deny_uninspected_body_credentials(ctx.secret_resolver.is_some()), pass
the resolver-presence check to both websocket_extension_mode call sites, and
apply the same guard there; add a regression test covering resolver-only
WebSocket upgrades and post-upgrade credential enforcement.

Nitpick comments:
In `@crates/openshell-server/src/grpc/policy.rs`:
- Around line 1097-1138: The provider layer composition in
effective_policy_for_source is gated by providers_v2_enabled, while credentialed
scopes and endpointless provider names are intentionally retained regardless of
that setting. Add a concise comment documenting this asymmetry at this site and
in sandbox_policy_merge_validation_data, without changing the existing behavior.
- Around line 2408-2448: The find_uninspected_credentialed_endpoint function
currently returns the first violation encountered in nondeterministic HashMap
iteration. Collect eligible uninspected credentialed endpoints, sort them by
rule_name, and return the first sorted result while preserving the existing
allow-uninspected warning behavior.
- Around line 2329-2338: Add a short comment in endpoint_ports documenting that
an endpoint with no declared port (ports empty and port zero) intentionally
matches every overlapping scope host, preserving the current fail-closed
behavior and preventing future changes from inverting this default.
In `@crates/openshell-supervisor-network/src/l7/rest.rs`:
- Around line 1093-1108: Replace the string-based credential-placeholder check
in the deny_uninspected_credentials branch with typed error matching. Update
relay_request_body_with_marker_guard to return a distinguishable
UninspectedBodyCredential error, construct that guard error via
miette::Report::new, and match the typed cause before calling
emit_uninspected_body_credential_denial.
In `@e2e/rust/tests/credential_gating.rs`:
- Around line 85-208: Consolidate write_provider_profile and
write_endpointless_provider_profile into one helper parameterized by the
optional endpoints section and display name, then consolidate install_provider
and install_endpointless_provider into one installer that uses the shared writer
while preserving endpoint and endpointless behavior and useful error context.

Changes
Two fixes to
