The Flight Recorder — follow one work id (a ticket, a payment, an incident) across the estate without a span warehouse. The tracing half of the RMAgent security observatory: a Security Trace Context (STC) carries case, principal, window, depth, ticket and trigger through every hop; the trajectory records the reasoning chain as an append-only DAG; the hop index remembers whether a principal has appeared before; the causal graph computes blast radius from kilobytes; OTel spans land in Grafana/Jaeger next to application traces. Use when a payment is slow, an incident needs a timeline, or security and reliability must read the same tape. Pull-based, capped, case-filed — not a lake.
