-# CURRENT PIN: the time_series_classification WS1 branch head
-# (data-ingestors#359, backend#1054/#1056) — the schema gains the
-# time_series_classification enum value + the sequence-column conditional,
-# and layout.v1 gains the grouping trait (Decision-4). Coupled release
-# (T16): once #359 merges, bump this to the merge commit on master and
-# re-run scripts/sync-schema.sh (a squash merge leaves this PR-branch SHA
-# fetchable, so CI stays green either way).
