chore(stack): update secure LLM component pins

[mikeyrcamp]

TL;DR

Update the self-managed stack to the secure LLM release set: Pylon and Stargate 0.14.1, request-router chart 1.12.0, gateway-routes chart 1.17.0, and OpenBao chart 0.32.1.

The stack pins the Stargate image independently from the request-router chart because the packaged chart default can lag the image release selected by the stack. The same pin is inherited by the backend router.

The API now receives the Pylon worker-sidecar image through its chart-native remote-config property, which has the required precedence over the packaged API profile. The deprecated environment key is translated for one compatibility window and conflicting values fail rendering.

• Keep the public/default make test lane offline.
• Add an explicit credential-required test-published-charts lane that renders the released router, gateway, and OpenBao artifacts.
• Assert both Stargate workloads use 0.14.1, the gRPC certificate and stream timeout policy render, UDP routing remains present, and no plaintext LLM TCPRoute is emitted.
• Pass arbitrary API environment and remote-config data through Helmfile while preserving stack-owned worker-address precedence.
• Default the canonical Pylon remote-config property to the effective sidecar registry and repository at 0.14.1; translate the deprecated environment key, omit it from the rendered environment, and reject conflicting or empty values.
• Update the BDD fixtures, version catalog, generated manifest, installation skill, and Pylon mirroring example.
• Provide a latest-main successor to fix(stack): bump self-managed stack chart pins #1313; that PR remains open for its author or a maintainer to disposition.

Merge gates:

• Confirm that the exact versions resolve from the public catalog.
• Run the fresh live multi-region BDD scenario against the merged discovery fix and these published pins. The earlier public test(bdd): cover secure multi-region Pylon registration #1310 success used an integration-only adapter; the later fix(llm-request-router): require explicit remote Watch URIs #1299 verification covered the corrected wiring without a live topology.
• Reconcile the updated control plane, then create and deploy a new LLM function version because existing versions retain their captured worker-sidecar image metadata.

For the Reviewer

Please focus on the independent Stargate image pin and inheritance, the API remote-config merge and compatibility contract, and the separation between offline and authenticated published-artifact tests.

For QA

Validated on a fresh latest-main VM worktree:

• make -C deploy/stacks/self-managed test
• make -C deploy/stacks/self-managed test-published-charts against the authenticated promoted catalog
• component chart test and lint targets for Cloud Functions, LLM request router, and gateway routes
• go test -short ./... under tests/bdd
• docs catalog generation check and Fern validation
• Go tooling build/vet/test check
• ShellCheck, Bash syntax, whitespace, stale-pin, DCO, and sensitive-string checks

Known baseline: three tools/docs-version-sync manifest tests fail for the existing bitnami-cassandra classification drift tracked by #1223. The repository's Go-tool checker explicitly excludes those tests while still building and vetting the module; the generated-document check passes for this change.

Issues

Relates to #1292

📝 Walkthrough

Walkthrough

The change updates release versions, moves LLM router client image configuration to API remote config, adds self-managed image and environment wiring, and adds published-chart and BDD validation.

Changes

Self-managed release and configuration

Layer / File(s)	Summary
Version pins and chart defaults deploy/helm/..., deploy/stacks/self-managed/helmfile.d/...	Updates Pylon, LLM router, OpenBao, and Gateway API image and chart versions.
API remote configuration and image resolution deploy/stacks/self-managed/environments/base.yaml, deploy/stacks/self-managed/global.yaml.gotmpl	Adds remote configuration merging, legacy Pylon variable translation, validation, and configurable router image tags.
API wiring validation deploy/stacks/self-managed/Makefile, deploy/stacks/self-managed/tests/api-env-wiring.sh	Tests configuration precedence, defaults, legacy compatibility, invalid values, conflicts, and rendered ConfigMaps.
Published chart integration tests deploy/stacks/self-managed/Makefile, deploy/stacks/self-managed/tests/*-published-chart.sh	Adds rendering and manifest checks for the Gateway API routes, LLM router, and OpenBao published charts.
References, manifests, and BDD wiring ai-tooling/..., docs/user/..., docs/version-catalog/main.yaml, tests/bdd/...	Updates configuration guidance, release references, fixtures, and BDD assertions for the generated API remote configuration.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 624d1

The stack pin and remote-config changes are otherwise mergeable, but whitespace-padded Pylon image values can still pass validation and be emitted unchanged, potentially producing invalid or unexpected image references; this requires explicit owner follow-up.

Fresh source-driven multi-region validation exposed one propagation gap: the BDD environment configured Pylon 0.14.1 under api.env, but the stack-generated nvcf-api values omitted configured API environment entries. The API chart therefore retained its Pylon 0.10.0 fallback in the worker launch configuration.

Fixed by 6233968:

• merge every configured api.env entry over the built-in stack environment
• preserve all unrelated built-in entries and emit each key exactly once in deterministic order
• serialize configured values as data without template evaluation
• prove Pylon 0.14.1 reaches both generated Helm values and the rendered nvcf-api ConfigMap

Validation at this exact head:

• focused Helmfile-to-nvcf-api ConfigMap regression test: pass
• full offline self-managed stack suite: pass
• nvcf-api Helm lint and template: pass
• focused Helmfile BDD wiring plus full short BDD suite: pass
• ShellCheck, Bash syntax, whitespace, DCO, targeted sensitive-string review, and offline changed-files TruffleHog scan: pass
• independent review: no Critical, Important, or Minor findings

Remaining merge gate: rerun the fresh live multi-region scenario from this exact head after reconciling the API workload and recreating any existing LLM function launch specification, then confirm the running worker uses Pylon 0.14.1. Public-catalog availability remains a separate release gate.

Lifecycle documentation correction added in b5e469f based on the fresh validation result: existing LLM function versions retain the worker-sidecar image metadata captured when the version is created. Replacing pods or redeploying the same version does not apply a new Pylon image. After updating the control plane, create and deploy a new function version.

This follow-up changes documentation only. The full docs check completed with Fern at 0 errors and one existing warning; whitespace, ASCII style, DCO, targeted sensitive-string review, and independent review all passed. No generated artifact update is required because the Fern navigation links directly to this Markdown source and the edit is outside generated catalog blocks.

The authoritative live rerun should use this exact head. No merge action was taken.

[mikeyrcamp]

Follow-up corrective commit: f6b800914f2ce715638b72caf037ec5065de7eb0

Live lifecycle proof showed that the Spring Kubernetes remote ConfigMap has higher precedence than the API environment. An environment-only Pylon override therefore could not reliably replace the published API chart profile's older default.

This commit makes api.remoteConfig.configData.nvcf.sidecars.llm-router-client-image the stack contract:

• arbitrary api.remoteConfig.configData and api.env entries are preserved;
• the stack-owned request-router worker address retains precedence;
• an enabled LLM addon defaults Pylon to the effective sidecar registry/repository at 0.14.1;
• the deprecated api.env.NVCF_SIDECARS_LLM_ROUTER_CLIENT_IMAGE key is translated for one compatibility window and omitted from the rendered API environment;
• conflicting, empty, whitespace-only, and non-string Pylon values fail clearly;
• BDD fixtures, public docs, and the generated installation skill use the chart-native path.

Sanitized validation:

• focused render test: explicit canonical value, computed default, nested passthrough, stack precedence, legacy translation, same-value compatibility, conflict/empty failures, and actual nvcf-api.yaml remote ConfigMap output;
• full self-managed stack suite: pass;
• BDD short suite: pass across all four packages;
• API Helm lint, kubeconform validation (11/11 resources), and sidecar release-artifact test: pass;
• generated installation skill: synchronized, idempotent, and unit-tested;
• Fern/docs check: 0 errors with the existing advisory warning;
• ShellCheck, Bash syntax, whitespace, DCO, targeted public-safety review, and changed-files TruffleHog scan: pass;
• independent senior re-review: Critical 0, Important 0, Minor 0, Ready.

The full BDD lint lane reports only two existing ST1005 findings in an untouched DSL helper; the changed BDD code is clean under the configured linters.

Remaining merge gate: run the source-driven live multi-region scenario from this exact commit. After the control-plane update, create and deploy a new LLM function version; replacing pods or redeploying the same version does not change worker-sidecar metadata captured at version creation.

Live BDD fixture correction: 624d11225b01e9c8f710811ff26c6e277d092d7f

The source-driven run confirmed that the new function version selected Pylon 0.14.1, but its image name still contained unresolved local-fixture placeholders. The BDD environment step applies only the dotted-path values listed by each scenario; it does not interpolate arbitrary fixture content.

This narrowly scoped fix removes the redundant explicit Pylon leaf from both local self-managed fixtures and removes the matching feature-table overrides. Local BDD paths now exercise the stack's computed canonical remote-config default from the effective registry and repository.

Regression coverage copies and renders both real fixture variants after registry configuration, then asserts:

• api.remoteConfig.configData.nvcf.sidecars.llm-router-client-image is exactly nvcr.io/sample-org/sample-team/pylon:0.14.1;
• the rendered property contains no REPLACE_WITH_ placeholder.

Focused and full self-managed stack tests, focused and full short BDD tests, API Helm lint/validation/tests, docs/Fern, ShellCheck, Bash syntax, changed-code lint, DCO, public-safety review, and changed-files TruffleHog all passed. Independent re-review reported Critical 0, Important 0, Minor 0, Ready.

The final live source-driven rerun should use this exact commit and create/deploy a new function version after reconciling the control plane.

[mikeyrcamp]

Focused live proof at head 624d112:

• The rendered configuration and live remote configuration were both placeholder-free.
• A newly created worker reached Ready 3/3 on Pylon 0.14.1 with running image digest prefix sha256:9befb43d30d5660ac.
• Sanitized metrics were registration=5, reverse=3, and regions=2.
• An authenticated chat.completion succeeded, with no no_eligible_candidates result observed.

This is focused proof only. The final fresh 2-scenario/63-step run from this exact head is now pending. No merge was performed.

[mikeyrcamp]

Final sanitized live acceptance result for a validation tree combining exact #1321 head 40bdda431fe25ee1e54f2cc8aec302d322ff0cb8, exact #1322 head 26070673a0e2e819ec2f5161a91ae24b5dc55ace, and current main containing #1300:

• Passed 2/2 scenarios and 63/63 steps in 955.96 seconds.
• Verified the certificate chain and hostname, ALPN h2, the Region B SAN and certificate readback, and HTTPS Watch.
• Observed 3 canonical Deployment identities and 2 canonical StatefulSet identities from an explicit HTTPS remote seed, with no dashed-IP aliases.
• Observed registration=5 and reverse QUIC=3, healthy authenticated backends, and a successful authenticated chat.completion with the fixed response and no no_eligible_candidates result.
• Running artifacts were Pylon 0.14.1 at digest prefix sha256:9befb43d30d5660ac and Stargate 0.14.1 at digest prefix sha256:97c621e4d8c65c636. These were the pinned promoted artifacts, not local sideloads.

Task cleanup is complete and zero task-owned clusters remain. #1321 automated checks and CodeRabbit are green; required human review remains. No merge was performed.
