- a record whose FCP understates the layout (the reported case: record_len 2
while the READ RECORD carried P3=0x2C and returned 44 bytes) had its rows
cut to two cells by the v2.7.3 length rule, hiding 42 newly-observed bytes
while the summary still counted them
- the filler now stops at the known length only while the data fits inside
it; beyond that — and when the length is unknown or absent — the row ends
at the data, so nothing observed is ever hidden and no bytes are invented
- verified on the live payload (session 55, 5f3a/4f09 change 0): before = 2
cells, both changed; after = 16+16+12 cells with 2 changed and 42 newly
observed, matching the summary line
- tests: the regression case (a 2-byte record_len with a 44-byte read) and
the unknown-length case, whose row now ends at the data; 527 Python +
76 Node tests
