Loki Mastery (Senior → Principal)

Operate

• Start from operator and security questions, not from collecting every log forever.
• Treat labels, retention, and query posture as architecture decisions.
• Prefer cost-aware log design with explicit tenant and compliance boundaries.
• Optimize for debuggability without creating cardinality or storage disaster.

Default Standards

• Labels must stay bounded and operationally meaningful.
• Query behavior should be predictable under multi-team load.
• Retention must match value, compliance, and incident needs.
• Multi-tenant controls should be explicit.
• Logging should support incidents, audits, and debugging without becoming chaos.
