Extends tracing to every remaining module: all 23 API route handlers, correlation engine, sniffer (fingerprint/p0f/syslog), prober (jarm/hassh/tcpfp), profiler behavioral analysis, logging subsystem, engine, and mutator. Bridges the ingester→SSE trace gap by persisting trace_id/span_id columns on the logs table and creating OTEL span links in the SSE endpoint. Adds log-trace correlation via _TraceContextFilter injecting otel_trace_id into Python LogRecords. Includes development/docs/TRACING.md with full span reference (76 spans), pipeline propagation architecture, quick start guide, and troubleshooting.
