Helm Mastery (Senior → Principal)

Operate

• Start from workload ownership, release safety, and chart readability.
• Treat Helm as a packaging and release contract, not as a free-form templating engine.
• Prefer charts that are boring to render, diff, review, and upgrade.
• Optimize for safe defaults, explicit values, and operational trust.

Default Standards

• Templates should remain readable by humans.
• Values must reflect ownership and safe override boundaries.
• Upgrades and rollbacks need known behavior.
• Chart APIs should evolve deliberately.
• One chart should not become a platform-in-a-file anti-pattern.
