 ## Remaining validation

 - Build the AI-enabled all-in-one image on Tower after the current inactive model training run finishes, verify Torch reports a CPU build and rerun live migration/browser smokes before replacing the runtime.

+# Sprint 171.1 - Validation coverage provenance
+
+- The expanded live export exposed that Arendonk-heide remained configured as a holdout while all of its low-variance tiles were correctly filtered out.
+- Added `retained_validation_sample_slugs` and `empty_validation_sample_slugs` to tile dataset summaries so configured and actual validation coverage cannot be confused.
+- Added a focused regression test and kept filtering behavior unchanged; no blank tile was reintroduced.
