The board's Logbook view replaces the published page: statistics, the chart of the executable, where the code stands (with the function tiers), the trend, milestones and the ship's log, stored as JSON in the Harbor home. A server thread follows main: each new commit becomes a log entry and the statistics, chart and trend point are rebuilt with the open-seas progress tools on a scratch copy.
