The serving-engine probe helper replaces an explicit initialDelaySeconds: 0 with 15. This silently overrides configurations that request no initial delay for startup, liveness, or readiness checks.

Check whether the field is present so zero is preserved and omitted values still default to 15. Add chart regression coverage for zero, positive, and omitted delays, and increment the chart patch version.

Validation: helm unittest helm passes all 25 suites and 148 tests. Applicable pre-commit hooks and helmlint pass. The zero-delay case fails against the unmodified helper for all three probes.

Code Review

This pull request updates the Helm chart to correctly handle and preserve an initialDelaySeconds value of 0 for startup, liveness, and readiness probes. Previously, using the default function caused 0 to be overridden by the default value of 15. This has been resolved by using the ternary and hasKey functions instead. Additionally, a new test suite has been added to verify this behavior under various scenarios, and the chart version has been bumped to 0.1.14. There are no review comments, and I have no additional feedback to provide.
