-## Legacy control trace v1
-
-The additive legacy characterization recorder is excluded from default builds. Build with
-`--features trace` and set `SQMA_TRACE_V1_PATH` to a JSON Lines output path to enable it at
-runtime. The format is versioned as trace v1 and is intended only for replaying the current
-baseliner and rate-controller boundary during the `SqmControlLaw` extraction; it is not the
-final runtime event schema. Existing CSV and metrics outputs remain unchanged.
