 # Tests tagged :verisim_data require the verisim-data git-backed flat-file store
 # to be cloned and populated by running hypatia-scan across the estate.
-# These tests pass in CI (where verisim-data is available) but are excluded
-# from local development runs to avoid spurious failures.
-# Run with: mix test --include verisim_data
+# These tests are CURRENTLY UNRUNNABLE in CI (verisim-data is not provisioned)
+# and fail 129/242 when run locally with --include verisim_data.
+# Excluded from all runs until verisim-data can be provisioned in CI.
+# See issue #692. Run with: mix test --include verisim_data
 # Pinned seed (#643): two CI runs with zero source changes differed by ±6
 # failures from seed alone, making failure-count deltas meaningless as
 # evidence. Pass --seed N explicitly to probe order-dependence.
