feat(reconcile): SDK inference route reconciliation (PR4b) - #99
Conversation
Add read/write inference-route support to the internal/openshell firewall, the seam later PR4b slices build on (plan diff, reconcile). - internal/openshell: InferenceRoute/InferenceRouteConfig harness types and three Client methods (Get/Set/DeleteInferenceRoute), no workspace arg (the client is bound to one workspace, as with Providers). - sdkclient/inference.go: implementation via c.raw.Inference(), a least-exposure fromSDKInferenceRoute mapper, all errors through translate. - Map gRPC InvalidArgument to a new ErrInvalidArgument sentinel: inference is the first firewall method whose user-supplied required fields can trigger it, so the raw SDK error no longer leaks past the firewall. - Tests (SDK fake): get/set/update-version/delete round trip, named-route isolation, idempotent delete, and closed-client + invalid-argument translation proving the sentinels are wired (not raw SDK errors). - Gated live Admin-role probe (TestLiveInferenceRoleProbe, HARNESS_E2E_GATEWAY) measuring whether the mTLS identity can write routes; skipped in CI.
Replace the flat inference validate with a real create/update/noop diff against the gateway's current route. - config.Inference gains TimeoutSecs() (duration string -> whole seconds), validated once at Resolve time so the pure plan builder can rely on it. - plan.ReadCurrentState reads the current inference route (only when inference is configured) into a widened InferenceState. A transient inference-read failure degrades to the not-capable validate fallback instead of flipping Reachable, since health and providers already proved the gateway reachable. - InferenceAction is the single owner of the create/update/noop rule, shared by the plan and (later) reconcile. An unset desired timeout means 'let the gateway default' and never forces an update. - isInferenceConfigured no longer counts Verify (a write modifier, not a route), so a verify-only config triggers no read or create. golangci-lint clean; go test ./... green.
Add internal/reconcile, the SDK-free write path that drives the gateway's inference route to match desired config. It shares plan.InferenceAction (single diff-rule owner) and, unlike the read-only plan, does not degrade: transient/permission/unsupported errors propagate so a caller learns the write did not happen. - config.Inference.Verify becomes *bool with VerifyEnabled() (nil->true), so unset means verify (the safe default) instead of the old always-skip. reconcile computes NoVerify = !VerifyEnabled() at the one mapping site, retiring the hardcoded --no-verify default. - plan.ReadInferenceState / plan.ResolveInferenceRoute are exported so reconcile reuses the route read and resolution (one owner each). Per user decision (option A), the physical swap of the legacy write site (cmd/providers.go:151) is deferred to PR4a: that apply path has no openshell target, so swapping it is the apply-on-SDK migration PR4b excludes. The engine ships ready for PR4a to call. golangci-lint clean; go test ./... green; internal/reconcile imports no SDK or cobra.
- plan.InferenceAction: treat a 0-second desired timeout as 'don't care' by guarding on the value, not the string. '0s' resolved to 0 but slipped the old desired.Timeout != "" guard, so it churned a perpetual update against the gateway's nonzero default (0 always stores the default, so '0s' can never be a stored value). '' and '0s' now behave identically. - config.Resolve: deep-copy Inference.Verify so the resolved struct never aliases the input's *bool, matching the PolicyRef pattern; add a parse+resolve round-trip test for verify:false. - reconcile: document that ReconcileInference does not gate on configured-ness (empty desired -> ErrInvalidArgument) and add a cross-path test locking plan and reconcile to the same InferenceAction. go test ./... green; golangci-lint clean.
Deployed OpenShell 0.0.110 to a real OpenShift gateway and drove the shipped reconcile engine against it (see the validate skill). Confirmed: the mTLS identity holds the workspace admin role (S1 risk retired), inference.local is the gateway default route, and create -> noop -> update -> delete all behave as designed. Two fixes the validation surfaced: - profiles/gateways/openshift.yaml: chart 0.0.85 -> 0.0.110. The 0.0.85 gateway returns Unimplemented on the inference gRPC; the profile was never bumped in the version re-baseline. Now in lockstep with .openshell-version. - inference_e2e_test.go: rewrite TestLiveInferenceRoleProbe. A real gateway accepts only a fixed route set and checks Set preconditions (route name, provider, credential) before the role, so the original scratch-route probe could never pass live. Read path runs always; the admin-write path is gated on HARNESS_E2E_INFERENCE_PROVIDER and restores pre-probe state.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Consider validating that a configured inference block sets provider and model.
isInferenceConfigured returns true when only route or only timeout is set. In that case InferenceAction compares an empty desired.Provider and desired.Model against a present route, returns ActionUpdate, and ReconcileInference then calls SetInferenceRoute with empty provider and model. The gateway rejects that write with ErrInvalidArgument, so the apply fails after the plan already showed an update with detail (provider/model unspecified).
A resolve-time check that requires provider and model when the inference block is present would reject the config early with a clear message.

SetInferenceRoute persists at the gateway before its gRPC response returns, so a write reporting a transport/unexpected error may still have changed state. The previous t.Fatalf in that path skipped restoration, potentially leaving inference.local pointing at probe-model. Register restoration with t.Cleanup before the write (fresh context, since ctx may be spent), skipping it only on a pre-write permission denial — where no write applied and the identity lacks the admin role the restore itself needs (CodeRabbit).
|
Addressed the outside-diff follow-up in 65fc605: restoration is now registered with I skipped the suggested "lost-response regression test": this is a gated live-only probe with no fake harness to inject an applied-write-then-lost-response, and the reconcile engine's error paths are already unit-tested in |

defer c.Close() runs during the test's goexit unwinding, before t.Cleanup callbacks, so it would shut the client's gRPC connection before the route-restoration cleanup could call Set/DeleteInferenceRoute. Register Close with t.Cleanup instead: registered first, LIFO ordering runs it last — after restoration (CodeRabbit).

What
Moves inference route configuration onto the OpenShell Go SDK with real
create/update/noop reconciliation and verify-by-default — the PR4b half of
docs/modernization/pr-04-provider-inference-reconciliation.md. Done before PR4a(providers) because it is the smaller slice and exercises the SDK write path
plus the Admin-role auth question cheaply.
Changes
internal/openshellfirewall gains inference vocabulary:InferenceRoute/InferenceRouteConfigtypes,Get/Set/DeleteInferenceRouteonClient, and anErrInvalidArgumentsentinel. Onlyinternal/openshell/sdkclienttranslatesto/from SDK types (the SDK-free firewall is preserved).
internal/plannow does a real inference diff:ReadInferenceStatereads thelive route;
InferenceActionis the single owner of the create/update/noop rule,shared by
harness planand reconcile. A transient inference-read failuredegrades to config-only (a secondary read must not declare the gateway
unreachable next to fully-populated providers).
internal/reconcile(new, SDK-free and cobra-free):ReconcileInferencereads, decides via
plan.InferenceAction, and writes only on create/update.Unlike the read-only plan it does not degrade — a write path must report
failure.
config.Inference.Verifybecomes*bool(nil -> verify).NoVerify = !VerifyEnabled()is computed at exactly one site; no hardcoded--no-verifysurvives in the new path.
0(""or"0s") means "letthe gateway decide" and never diffs (the gateway can't store 0).
Scope note (see PR4a)
The physical swap of the one legacy write site (
cmd/providers.go:151) isdeferred to PR4a. That site lives in the legacy
apply/upLocalpath, whichhas no
openshell.Client/Factory/resolved target — so swapping it is theapply-on-SDK migration PR4b excluded. PR4b ships the reconcile engine ready for
PR4a to call;
gw.InferenceSetand its teardown caller stay until then.Live validation (real 0.0.110 gateway on OCP, 2026-08-25)
Deployed OpenShell 0.0.110 to an OpenShift cluster and drove the shipped engine
against it. Confirmed:
succeed (the S1 risk is retired).
inference.localis the gateway's default route (plan.DefaultInferenceRoute).verify:truewrite against a badendpoint was really rejected).
Two fixes the validation surfaced (final commit):
profiles/gateways/openshift.yaml: chart0.0.85->0.0.110. The0.0.85gateway returns
Unimplementedon the inference gRPC; the profile was missed inthe re-baseline. Not in any CI lane (only
make test-remote), so zero CI blastradius.
TestLiveInferenceRoleProbe: rewritten. A real gateway accepts only a fixedroute set and checks
Setpreconditions (route name, provider, credential)before the role, so the original scratch-route probe could never pass live.
