`runtime compare-region-fixed-row-runs p.gms q.gms` shows shared shape-family matches even
though the best raw `rows_offset` drifts between saves, so the tri-lane-adjacent row family
should be treated as a stable shape-family seam rather than a fixed-offset seam
- the periodic-company trace now carries that save-native seam directly too:
it exposes the current top tri-lane-adjacent fixed-row shape-family candidates with row-count,
stride, rows-offset, and probable-density-lane hints, so the tri-lane frontier is now
structured as “save shape-family candidates present, fixed offset ruled down” instead of only
a prose note
- the `0x5dc1/0x5dc2` serializer bundle is tighter now too:
atlas-backed recovery bounds `0x0040c980 -> 0x0045b560` as emitting the derived payload over
`[site+0x23e/+0x242/+0x246/+0x24e/+0x252]`, so the remaining restore-owner question should
