Generalising the TCAF_608 test across the 5296 over-declaring banks first looked like a clean reversal: 59 of 60 gained audio (median 2.10x) from reading the full declared size instead of stopping at the TOC window. Then I tested whether the declared size is an honest boundary by reading TWICE it. 33 of 40 yield >1.5x more audio, median ratio 1.64. The decoder keeps going indefinitely, because XMA1 packets are self-contained -- the next bank's packets decode perfectly well and are simply not this bank's. A byte count cannot tell them apart. So the 59/60 is withdrawn as evidence for anything. Same error as the unanchored 'data' search earlier on this page: a measurement returning a plausible number for a question it cannot answer. What survives: TCAF_608 is genuinely anomalous (86x more input, zero extra output, where the typical bank yields without limit); the honest-size question is unresolved and needs a boundary signal independent of the decoder, such as the seek-chunk packet chain; and the only measured fact is that the declared size exceeds the TOC window for 5296 of 7586 banks.
