Show HN: An OTel exporter that posts the cause to your incident channel

Incidentary provides shared causal traces for incident response, helping teams understand what caused an incident before the war room starts. It uses an OpenTelemetry exporter to capture outbound calls, errors, and slow queries, building a causal graph in real time. When an alert fires, it delivers an artifact showing where the failure first appeared, when, how it spread, and what to look at next — all without AI inference.
