`B905` over 56 sites, and the answer differs by idiom rather than by file.
21 were the sliding window `zip(xs, xs[1:])` — ragged by exactly one, on
purpose, so `strict=` is the wrong question entirely. Those become
`itertools.pairwise`, which is what they always meant and needs no flag: the
walk's SNR stops, the heat ladder, the route chains in `topology`/`records`,
every polyline in `mapcanvas`, and the graph's edge sets in `pathgraph`.
The other 35 pair sequences that must line up, so they now say `strict=True`
and a mismatch raises instead of silently truncating the longer side. Running
them under that assertion is what sorted the two groups: the first pass put
`strict=True` everywhere and 208 tests failed, all of them a sliding window.
One goes the other way. `mvt._decode_feature` reads tags off a network tile,
where an odd-length list means the tile is malformed — and this decoder answers
that with a shrug everywhere else (`if not geom_ints: return None`, bounds-
checked key and value indices). It keeps `strict=False`, now with a comment
saying why, so a bad basemap tile still can't crash the map.
