+files. The current normal artifact passed genuine repeated English recognition
+from Unicode paths with CPU forced. Fifty owned-process samples observed the
+CPU backend and no Vulkan modules; sampling alone does not prove absence at
+every instant. The pinned CPU-only loading branch complements that observation.

+## Frozen independent retrieval
+
+The four-file fixture retained both real English/German recordings, instrumental
+music and silence, plus all ten frozen queries. Six positive queries found a
+relevant file first, with recall@5 also 6/6. Music and silence produced zero
+accepted recognized passages. **All four absent queries still returned files.**
+The two readings share translated subject matter; this is a small file-retrieval
+test, not broad media accuracy or verified passage/word timing.
+
+Every expected window input and published citation passed source validation,
+including four windows across the two separate artificial seam sources.
+Transcription errors, partial boundary phrases and overlap duplicates remain in
+the evidence. Concept substring coverage is not a word-error score. Root
+independently recomputed the exact recorded scorer output.
