Fibo — git blame for your promises

Field notes

Fibo compares an estimate recorded before work began with the elapsed interval from first commit to merge, using working-hour rules and a log-space median to produce a multiplier. Its demo contains two years of made-up history: 230 tasks appear, 169 count toward the result. The page also exposes commands for recording estimates, inspecting individual tasks, viewing quarter-by-quarter drift, and checking whether repository data has been altered.
