Integrate Kubernetes Launch Kit network validation - #581
Conversation
📝 WalkthroughWalkthroughThe change adds a Kubernetes Launch Kit provider, six Network Operator validation workflows, orchestration lifecycle controls, structured subtest reporting, recursive suite discovery, requirements traceability, documentation, fixtures, and comprehensive tests. ChangesNetwork Operator Launch Kit integration
Estimated code review effort: 5 (Critical) | ~90 minutes Merge Risk: 🟡 Moderate · up to The Network Operator workflows can incorrectly pass incomplete or malformed validation results and reject valid relative evidence paths. These issues should be fixed before merge. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Addressed all seven CodeRabbit findings in amended commit 505cfa9: corrected the transport example and catalog note; made complete user configs transient and retained only safe provenance; made installer execution require an immutable commit plus a trusted SHA-256; completed subtest totals with legacy fallback; rejected missing or invalid DaemonSet rollout counts; and added the missing helper docstring. Added regression coverage for each functional/security path and regenerated the test-plan output. Validation is clean: 1,713 isvctl tests, 58 isvreporter tests, 1,687 isvtest unit-selected tests, 128 script tests, Ruff lint, requirements traceability, plan coverage, and suite wiring. All review threads are resolved. |

Add a generic Launch Kit provider and six Network Operator east-west networking use cases. The production Network Operator workflow validates an ISV-provisioned cluster through preflight, discover, generate, and validate without invoking Launch Kit deploy or clean. Preserve Launch Kit evidence while exposing reusable semantic checks and use-case-level reporting. Consume GPUDirect DMA-BUF results with endpoint GPU, PCI, bandwidth, and threshold diagnostics, and register the applicable checks in the catalog. Extend orchestration and reporting with named phases, validation-aware workflow pruning, structured composite subtests, process-group timeouts, recursive suite discovery, and accurate JUnit failures for command-stage errors. Keep lifecycle commands available in the generic provider while allowing prerequisite checks and evidence validation to follow the command subset selected by a consuming workflow. Document the provider contract, the validation-only ownership boundary, prerequisites, catalog metadata, PRD coverage, evidence handling, and remaining integration gaps.

Do not treat unknown rails as cross-rail coverage.
_matrix_probes uses "unknown-rail" when an endpoint rail is missing. Comparing that fallback with a known rail classifies known-rail -> unknown-rail as cross-rail. A multirail validation can then pass without evidence that two real rails were exercised.
Require both rail values to be known before counting a row as same-rail or cross-rail.
