# @v2/telemetry-alerting-rules

Phase 72.5.2.13 alerting rules for live telemetry operations.

`buildV2TelemetryAlertingRulesSurface` evaluates aggregate samples for:

- `crash-rate-spike-2x`: crash rate at least 2x the baseline
- `player-count-drop-20pct`: player count drop of at least 20%
- `matchmaking-wait-time-3min`: p95 matchmaking wait time at least 180 seconds

The service composes `@iris/analytics-realtime` alert rule types and emits
deterministic alert records for operators and CI gates. Inputs are aggregate
operational samples only; raw account IDs are not accepted or emitted.
