Drainage and flooding

Scores of the written record, normalized by era. Minutes are the clerk's summaries, not transcripts: tone is muted and the style changed with each clerk and era, so every score is compared only with meetings of the same minute-style era (1962-1979 narrative minutes, 1980-2004, 2005-2016, 2017 on) and shown as a percentile of that era. Signals: divided and failed votes, motions that died for lack of a second, tabled or postponed items, amended motions, ordinance readings that stalled, hearings with objections, public appearances, the length of an item's discussion compared with its era, and words such as "objected", "protest", "concern", "thanked" or "commended", each kept with the sentence it came from. Only pages whose reading scores at or above the archive's score target count. The record is scored, not people: no resident is named or scored, and members appear only through their recorded votes. Meetings named as the most contentious or most congenial are published only after a person reviewed them.
