+# TTS() never returns from the native call, so tests-qwen3-tts-cpp goes from
+# ~5 minutes to the 20 minute Go test timeout. Reproduced on master on
+# 2026-08-01 and again on re-run, and the bump PR (#11241) was merged with

+# The regression is in 35ebe537..abab6b3, three upstream commits whose only
+# functional change is 26dd8adb, "predictor: unroll the frame into one cgraph
+# and sample in standard ops". Restore the bump once that is fixed upstream.
