Summary

  1. Invalid compatibility values (e.g. hard-requirement) were accepted without error and silently treated as best_effort. Fixed by parsing into an enum at YAML parse time and TryFrom implementation at the proto conversion layer.
  2. hard_requirement with no filesystem paths configured was a silent no-op, Landlock skipped entirely. Fixed by erroring before the early return when hard_requirement is set and both path lists are empty.

Related Issue

closesNVIDIA#2356

Changes

Two fixes to landlock.compatibility enforcement. Invalid values now fail at YAML parse time instead of silently falling back to best_effort. Configuring hard_requirement with no filesystem paths now aborts sandbox startup instead of skipping Landlock entirely. Docs updated to reflect the new behavior.

Testing

  • mise run pre-commit passes
  • Unit tests added/updated
  • E2E tests added/updated (if applicable)

Checklist

  • Follows Conventional Commits
  • Commits are signed off (DCO)
  • Architecture docs updated (if applicable)

Summary by CodeRabbit

  • New Features

    • Added headless OIDC login with device authorization and PKCE.

    • Added allow-uninspected-credentials policy support for exceptional credentialed endpoints.
  • Bug Fixes

    • Credentialed traffic now fails closed when inspection or rewriting is unavailable.
    • Invalid Landlock compatibility settings are rejected with clear errors.
    • Hard-required filesystem protection now rejects empty configurations.
  • Documentation

    • Updated policy, authentication, security, and CLI guidance for these behaviors.

📝 Walkthrough

Walkthrough

The changes add typed Landlock validation, hard-requirement enforcement, provider credential provenance, fail-closed network traffic handling, OIDC device authentication, fresh-login markers, CLI support, SDK conversion, tests, and documentation.

Changes

Landlock compatibility handling

Layer / File(s)Summary
Typed compatibility and conversion
crates/openshell-core/src/policy.rs, crates/openshell-policy/src/lib.rs
Landlock values are restricted to best_effort and hard_requirement. Invalid proto and YAML values now return errors.
Hard-requirement setup
crates/openshell-supervisor-process/src/sandbox/linux/*, docs/reference/policy-schema.mdx
Empty hard-requirement filesystem policies fail. Best-effort policies remain no-ops. Readiness events distinguish both outcomes.

OIDC authentication flows

Layer / File(s)Summary
Device authorization flow
crates/openshell-cli/src/oidc_auth.rs
The CLI supports device discovery, PKCE requests, user instructions, token polling, RFC 8628 errors, and token validation.
Fresh-login marker lifecycle
crates/openshell-bootstrap/src/oidc_token.rs, crates/openshell-cli/src/commands/gateway.rs
Logout records a per-gateway marker. Successful login clears it. Registration cleanup removes it.
CLI and authentication documentation
crates/openshell-cli/src/main.rs, docs/reference/gateway-auth.mdx, docs/kubernetes/ingress.mdx, architecture/gateway.md
Help text and documentation describe device-code PKCE and fresh identity-provider prompts.

Credential-gated network policies

Layer / File(s)Summary
Policy fields and conversions
proto/sandbox.proto, crates/openshell-policy/*, crates/openshell-providers/profiles.rs, sdk/go/openshell/v1/*
Endpoints support allow_uninspected_credentials and provider_credentialed across policy, protobuf, provider, and SDK conversions.
Gateway provenance and validation
crates/openshell-server/src/grpc/{policy,sandbox}.rs
The gateway derives credential scopes, stamps endpoint provenance, validates policy updates and merges, and rejects uninspected credentialed endpoints without explicit opt-in.
Supervisor enforcement
crates/openshell-supervisor-network/src/{opa.rs,proxy.rs}, crates/openshell-supervisor-network/src/l7/*, crates/openshell-supervisor-network/data/sandbox-policy.rego
CONNECT, REST bodies, WebSocket text, and binary frames are denied when credential traffic cannot be inspected or rewritten.
Credential marker scanning
crates/openshell-core/src/secrets.rs, crates/openshell-supervisor-network/src/l7/rest.rs
Raw and percent-encoded markers are detected across binary and streamed request bodies.
Validation and documentation coverage
e2e/rust/tests/credential_gating.rs, docs/sandboxes/*, docs/security/best-practices.mdx, .agents/skills/*
Integration tests and documentation cover admission checks, opt-in behavior, REST handling, WebSocket handling, and security warnings.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk:🟠 High · up to 2992e

This PR changes credential enforcement and authentication behavior, but the current version still has a reported build failure and several paths that can admit or mishandle credentialed traffic, omit required security findings, hang during login, or leave failed registrations behind. The PR should not merge until these correctness, security, and availability issues are fixed.

…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.

* 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.

* 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.

* 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.

* 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

* 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

* 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://

* 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

* 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

1140-1160: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

The device-code branch ignores force_fresh_login.

gateway_logout sets the marker so that the next login asks the identity provider for a fresh prompt. The browser branch honors that marker. The device-code branch does not pass it to oidc_device_code_flow, and Line 1174 clears the marker after the token is stored. After a logout followed by a headless login, the user can silently reuse the existing identity provider session, and the marker is consumed.

Either forward the flag to the device authorization request as prompt=login, or keep the marker when the device flow cannot honor it.

Include the bound resolver in WebSocket credential denial.

When ctx.secret_resolver.is_some() and provider_credentialed is false, the upgrade can use the raw relay. Post-upgrade frames then bypass credential-marker checks and binary-frame denial.

Use config.deny_uninspected_body_credentials(ctx.secret_resolver.is_some()) in upgrade_options. Pass ctx.secret_resolver.is_some() to both websocket_extension_mode call sites and use the same guard there. Add a resolver-only WebSocket regression test.

85-208: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Consider collapsing the two profile and install helpers.

write_provider_profile and write_endpointless_provider_profile differ only in display_name and the presence of the endpoints block. install_provider and install_endpointless_provider differ only in the profile writer and the error text. A single writer that takes an optional endpoints section, plus one install helper, removes the duplication and keeps the two profiles in sync when the credential schema changes.

Replace error-string matching with a typed error.

The branch decides whether to emit the OCSF denial by testing error.to_string().contains("credential placeholder"). Any future rewording of the guard message silently disables the denial telemetry. Return a distinguishable error from the guard instead.

♻️ Proposed refactor
+#[derive(Debug, thiserror::Error)]+#[error("request body credential placeholder denied because rewrite is disabled")]+struct UninspectedBodyCredential;+

Then construct the guard errors with miette::Report::new(UninspectedBodyCredential) and replace the check:

- if error.to_string().contains("credential placeholder") {+ if error.downcast_ref::<UninspectedBodyCredential>().is_some() {
emit_uninspected_body_credential_denial(req, &options);

1097-1138: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Credentialed scopes are derived even when provider composition is disabled.

effective_policy_for_source and sandbox_policy_merge_validation_data gate provider_layers on the providers_v2 setting but always keep credentialed_scopes and endpointless_provider_names. This is correct because provider credentials reach the sandbox regardless of that setting. Add a short comment at both sites so the asymmetry is not removed later as an apparent inconsistency.

2408-2448: 🎯 Functional Correctness | 🔵 Trivial | 💤 Low value

Violation selection is nondeterministic across network_policies.

find_uninspected_credentialed_endpoint iterates a HashMap. When a policy contains several violating endpoints, the reported rule and host change between runs. Operators then see a different rejection message for the same policy. Collect the violations and select the first by sorted rule name if stable messages matter.

Endpoints with no declared port match every scope host.

endpoint_ports returns an empty vector when ports is empty and port is 0. endpoint_matches_credentialed_scope then returns true for any host overlap. This only widens the stamped set, so it stays fail-closed. Record the intent in a short comment so a later change does not invert the default.

 fn endpoint_ports(endpoint: &NetworkEndpoint) -> Vec<u32> {
+ // An endpoint with no declared port yields an empty list. Scope matching+ // then treats it as "any port", which over-stamps rather than under-stamps.

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.

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.
