📝 Walkthrough

Walkthrough

The Helm chart now uses stable KAS key-management configuration while accepting the deprecated preview field. Templates share detection and secret validation across both paths. Tests cover configuration combinations and default rendering.

Changes

KAS key management

Layer / File(s)	Summary
Stable KAS configuration contract charts/platform/Chart.yaml, charts/platform/values.yaml, charts/platform/README.md	The chart version is updated. KAS key_management moves to the stable configuration level. The deprecated preview field remains documented as compatible.
Key-management detection and deployment wiring charts/platform/templates/_helpers.tpl, charts/platform/templates/deployment.yaml	Templates detect key management from either configuration path, validate both root-key secret values, and inject the root-key environment variable when enabled.
Compatibility test coverage tests/chart_platform_template_test.go	Table-driven tests cover stable and preview flags, secret validation, and default configuration output.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to c77e4

The chart changes are currently not release-ready because the version remains 0.16.0 despite that version already being published; releasing it unchanged could cause consumers to receive or reference the wrong chart artifact. Increment the chart version before merging for release.

Poem

A rabbit checks the KAS gate,
Stable keys now set the state.
Preview paths still hop along,
Root secrets guard the deployment song.
Tests nudge each flag in line.
