Databases have offered materialized views for decades, and every time-series database rolls up its metrics as they arrive. So the useful questions about Precomputing are narrower: what does this version do that the others don&rsquo;t, and which parts would a rival struggle to copy?</p> <p>The answer comes in two halves. What sets it apart today is where it runs and how much it covers. One small policy language drives four jobs that usually take four separate products, and all of it lives in an ordinary SQLite file. What makes it hard to copy is the proof work behind those claims: two runtimes that write the same file to the last bit, and exact counts checked against separate recounts, crash after crash.</p>
