  "decoding": "Each year file has `columns`, `codebooks` and `rows`. A row is positional against `columns`; a row shorter than `columns` has its remaining fields absent. Integer values of a column named in `codebooks` index that codebook. Join `law` to rows in laws.json for the law's scope, canton, domain and type. `chars`/`articles` there are the law's size today, held once per law rather than per event so they cannot be summed twice; `latest` is the date of the event that produced that text. `delta` is [lines_added, lines_removed, words_added, words_removed]; a null means that unit was not measured for the event, which is not the same as zero. Lines come from this corpus's own diff and exist for federal revisions; words cover cantonal revisions too, diffed from LexFind's version series."
