Investigated multi-segment Tran continuation but couldn't crack it.
Each hypothesis tried (segment header consumes 0/1/2 T deltas, blocks
continue Tran with various interpretations) breaks at sample ~512.
Block budget for V70 segment 1: 264 nibbles + 244 RLE zeros = 508
deltas — exactly the segment size. So the block structure CAN encode
508 single-channel samples, but applying segment 1 blocks as Tran
gives wrong values.
Most likely the channel ordering changes in segment 1+ (e.g., segment
0 = Tran, segment 1 = Vert, segment 2 = Long, etc.) but I couldn't
verify cleanly. Stopping here — segment-0 Tran decode is solid and
multi-segment work needs more fresh thinking.
