Where the seats came from
Per-council net seat change vs each council's prior appearance in our dataset (typically that council's previous all-out election or its last by-thirds slice). "Debut" rows are councils whose first cycle in our window is 2021 — usually the result of a boundary reorganisation or being a county outside our 2021 LEH coverage.

Net-change comparisons are versus each council's most recent appearance in our dataset (2021–2026). For all-out councils that's the previous all-out cycle (typically four years prior); for by-thirds councils it's last year's slice. Cross-cycle ward boundary changes can produce small artefacts — see methodology.
