Chapter 7 — SLO / Error Budget Tracking System
Chapter of Observability Pipeline & Data Infrastructure, part of System Design.
Purpose
Burn rate calculation, multi-window alerting, budget ledger — written up as a conceptual chapter in the observability book rather than duplicated here; see SLOs & Error Budgets for SLI/SLO/SLA, the error budget as a spendable resource, and the multi-window multi-burn-rate alerting table.
[stub: slo-error-budget-tracking-system]— this chapter is still a placeholder for the system-design-specific treatment (the actual tracking-system architecture: ledger storage, capacity numbers, worked practice questions). Greppable doc-debt marker.
