:::
Name the patches which must be split but state no sampling interval.

The pieces are found on the patch's own sample grid, which its step
is the only description of: a piece ends one step short of where the
next begins. Without a step both pieces would have to claim the
boundary value, and envelopes are inclusive, so a sample landing
there would appear in both. Duplicating a sample is a worse answer
than saying so — the caller asked for the metadata to be reconciled,
not for the data to be restructured.
