Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The SDK foundation is otherwise mergeable, with a pinned dependency, additive firewall interfaces, and passing build and test checks. Owner follow-up is still needed because the historical modernization plan may encourage a forbidden replace directive in future changes. Sequence Diagram(s)sequenceDiagram

Introduce the OpenShell Go SDK behind a harness-owned firewall and prove an mTLS Health check works from within the harness module. - internal/openshell: firewall interface (Client, Target, Health, Provider, Factory) + six Err* sentinels. Zero SDK imports (enforced by grep probe). - internal/openshell/sdkclient: the sole production SDK importer. New() dials an mTLS gateway via gateway.NewClient(name, WithAuth(NoAuth()), WithTLS(certs)) from the CLI-managed cert dir; wraps v1.ClientInterface bound to one workspace; Health/Close implemented, Providers stubbed until the translation slice. - go.mod: SDK pinned to proxy-resolvable pseudo-version v0.0.0-20260818204536-8d67250a5d17 (commit 8d67250a; public repo, sdk/go subdir module, no vX tag). No replace directive; real go.sum hashes. - Tests: sentinel distinctness/wrappability; guarded mTLS Health E2E (HARNESS_E2E_GATEWAY) — passes against local gateway (healthy, v0.0.85). - .gitignore: keep local planning artifacts (specs/, docs/modernization/) out of tree.

Inline comments:
In `@docs/modernization/pr-01-sdk-foundation.md`:
- Around line 32-34: Update the SDK dependency checklist in
pr-01-sdk-foundation.md to remove the recommendation to use a replace directive,
or explicitly mark that advice as stale; retain the requirement for a
proxy-resolvable pinned pseudo-version.
In `@specs/pr1-sdk-foundation/README.md`:
- Around line 81-84: Update the dependency description in the README to match
the intended state: either label it explicitly as pre-S1 and retain the no-SDK
description, or revise it to list the SDK dependency already pinned by S1. Keep
the surrounding Go version and dependency details consistent with the selected
state.
In `@specs/pr1-sdk-foundation/slices/01-dep-and-mtls-health-gate.md`:
- Around line 91-94: Update the S1 verification gate to remove the unavailable
harness doctor --gateway command, leaving only the guarded HealthE2E test that
skips when no gateway environment is configured. Add or retain the Doctor
command documentation in the S5 section instead.
In `@specs/pr1-sdk-foundation/slices/05-doctor-rewire.md`:
- Line 42: Align the bullet containing checkOpenShell, checkTargetDeps, and
checkProviderEnvVars with the surrounding list nesting in the relevant Markdown
section, then verify the document passes markdownlint without MD005.
- Around line 20-21: Update NewDoctorCmd and the related flow to explicitly own
and close every client successfully returned by the openshell.Factory. Define
and implement the required behavior when Client.Close() returns an error,
including whether that error changes the doctor command result, and keep the
ownership semantics consistent across all referenced lines.

…apping (PR1 S3) (#91) * feat(sdkclient): complete Client with dial, translate, and provider mapping (PR1 S3) Third slice of the PR1 SDK-foundation ladder (S1 #89, S2 #90). Completes the working openshell.Client over the OpenShell SDK, behind the harness firewall. - dial(connPlan) executes every auth branch: mTLS (verified live), default, and SA-OIDC (dialSAOIDC; compiled and branch-selected but // UNVERIFIED — no OIDC gateway available; gates PR8). - errors.go: translate() is the single owner of SDK-error meaning, mapping v1.Is* typed errors to the openshell.Err* sentinels; unknown errors pass through unchanged. Callers branch via errors.Is, never on SDK codes. - provider.go: fromSDKProvider maps the SDK provider view to the minimal harness Provider (least-exposure firewall). - NewFromClient is the injection seam (used by white-box tests and S4 testutil); New now routes through the general dial(plan) path. - Health() and Providers() are live and route errors through translate(). - connPlan gains non-secret oidcIssuer/oidcClientID for the SA-OIDC dial; the client secret is still never stored in the plan (re-read at dial time only). White-box tests via the SDK fake cover Health (healthy/unhealthy), Providers (with/without), translate (all SDK codes + nil + passthrough), error translation on a closed client, and Close idempotency. Firewall unchanged: internal/openshell/sdkclient remains the only production package importing the SDK; internal/openshell has zero SDK imports. Additive only. * fix(sdkclient): make SA-OIDC token source genuinely refreshing Addresses CodeRabbit review on PR #91. oidc.ClientCredentials returns a one-shot token that expires, and v1.RefreshableToken re-calls its source once the cached token nears expiry — so oauth2.StaticTokenSource pinned a single token and would break auth the moment it expired. Replace it with an eager grant (preserving fast-fail ErrUnauthenticated classification) wrapped in oauth2.ReuseTokenSource(tok, refresher), where the refresher re-runs the client-credentials grant on a context.WithoutCancel context so refreshes outlive the dial call while keeping context values. The eager token is served first (no wasted grant). Secret is read fresh from the environment inside the source at grant time and never stored on the plan. Path remains // UNVERIFIED (no OIDC gateway); gates PR8. * fix(sdkclient): bound each SA-OIDC grant with a timeout Addresses follow-up CodeRabbit review on PR #91. context.WithoutCancel strips the parent deadline as well as cancellation, so a stalled OIDC token endpoint could block a background token refresh indefinitely. Bound both the eager grant and every refresh grant with their own context.WithTimeout(oidcGrantTimeout=30s), cancelled after the grant. Token reuse and the existing clientCredentials invocation are preserved. Path remains // UNVERIFIED (no OIDC gateway); gates PR8.

What
Introduce the OpenShell Go SDK behind a harness-owned firewall, and prove the mTLS escape hatch works from within the harness module. This is the risk-retirement foundation for migrating harness reads onto the SDK: if the SDK dependency closure wouldn't build in-module, or an mTLS
Health().Checkwouldn't succeed against a real gateway, the SDK-first approach would be in question. Both are now proven.Changes
internal/openshell— harness-owned firewall:Client/Factoryinterfaces,Target/Health/Providervalue types, sixErr*sentinels. Zero SDK imports — SDK types never leak past this package (enforced:grep -rl NVIDIA/OpenShell internal/openshell/*.gois empty).internal/openshell/sdkclient— the only production package that imports the SDK.New()dials an mTLS gateway viagateway.NewClient(name, WithAuth(NoAuth()), WithTLS(certs))using the CLI-managed client cert under<cfg.Dir>/mtls; wrapsv1.ClientInterfacebound to one workspace.Health/Closeimplemented;Providersreturns a not-yet-implemented error (error-translation lands in a follow-up).go.mod— SDK pinned to proxy-resolvable pseudo-versionv0.0.0-20260818204536-8d67250a5d17(commit8d67250a). NVIDIA/OpenShell is public;sdk/gois a subdirectory module with nosdk/go/vXtag, so a pseudo-version at the commit is the correct pin. Noreplacedirective; real checksum-DB hashes ingo.sum.Scope / non-goals
Purely additive. No command wiring changes —
doctor,apply,deploy,internal/gateway, andinternal/k8sare untouched. SDK inference is deferred (gateway 0.0.85 returnsUnimplemented); file transport stays on the CLI.Verification
