Availability target

The **desired percentage of successful requests** over a window — feeds SLOs and SLAs.

#When to use

Setting error budgets for chat APIs and comparing canary vs stable traffic.

#When not to

Single-metric vanity goals without quality guardrails — availability without groundedness misleads.

#Example

Target 99.9% successful `/chat` responses excluding client 4xx; alert when burn rate doubles.
