  "message": "perfetto: fix bogus chunks_overwritten in TraceBufferV2\n\nDeleteNextChunksFor() unconditionally bumped chunks_overwritten /\nbytes_overwritten for any non-padding chunk it walked, while data_loss\nwas correctly gated on has_cleared_unconsumed_fragments. The two should\nmove together: a chunk that the reader already drained (payload_avail\n\u003d\u003d 0) but hadn\u0027t yet \"stepped past\" via the follow-up\nReadNextTracePacket() call is still non-padding, and clearing it on a\nsubsequent wrap is not a real overwrite.\n\nMove the stat increments inside the same gate as data_loss so they\nonly fire when there were actually unread fragments at clear time.\nThis matches v1 (trace_buffer_v1.cc only counts when num_fragments_read\n\u003c num_fragments).\n\nAlso adds NoOverwriteCountIfReaderCatchesUp, which mirrors the\nexisting NoDataLossIfReaderCatchesUp pattern but asserts on the stats\nthe latter never checked.\n",
