 - ECC-Tools PR #36 added deep-analyzer predictive follow-ups, a Deep Analyzer
   Evidence PR-risk bucket, and a Linear-ready project sync backlog table for
   deferred follow-up work.
+- ECC-Tools PR #37 added a maintained analyzer corpus fixture, corpus validation
+  tests, and co-located analyzer reference-set evidence recognition for future
+  predictive follow-ups and PR-risk taxonomy checks.
 - ECC PR #1803 landed the contributor Quarkus handling branch after maintainer
   cleanup, current-`main` alignment, full local validation, and preservation of
   the author's removal of incomplete ja-JP and zh-CN Quarkus translations.
