Inqudium

Tabellarium is a resilient Logback appender that ships structured log events to Apache Kafka. Named after the Roman letter-carrier, it never blocks the sender: per-topic-class circuit breakers stop hammering a broken route, mandatory overrides pin the strictest producer-side delivery settings for audit-class topics (acks=all, idempotence), and a fallback appender catches what cannot be shipped. Delivery is best-effort transport: events are handed off through bounded in-memory queues, so a crash, overflow, or expired shutdown budget can lose events - the appender is not, by itself, a durable audit trail.

Limesium - one structured endpoint_* log line per HTTP exchange, recorded at the service's own boundary (the "limes"). Two paradigm twins with identical fields and configuration: a servlet filter and a WebFlux/coroutines web filter.

Legatium - one structured adapter_* log line per outbound HTTP exchange, recorded where the service sends its envoy (the "legatus") to a foreign party. Two paradigm twins with identical fields and configuration: a RestClient/RestTemplate interceptor and a WebClient filter.
