Failure mode
Freshness Failure
A failure mode where data arrives too late, updates too slowly, or becomes stale relative to the decision window the system is expected to support.

Signals
- dashboards and agents show internally consistent answers that are already out of date
- late arrivals or update lag create false confidence about current state
- operational teams find that the system describes disruption after the fact instead of during it
Why it matters
Freshness is not a vanity metric in present-tense systems. It determines whether the platform can support intervention. A stale system may still be analytically elegant and operationally useless.
Prevention patterns
- freshness SLOs tied to actual operational decisions
- explicit late-arrival handling and backfill policy
- monitoring that distinguishes ingestion success from decision-readiness
