Most tools guess faster. We refuse to guess.
The industry’s reflex is to make answers appear sooner. We think the appearance of an answer is the problem.
A capacity margin is either supported by the inputs or it isn’t. A match is either justified by the evidence or it’s a question for you. So VentScan recalculates from written specs, carries units and maturity on every number, surfaces uncertainty instead of smoothing it over, and changes nothing without your approval.
It is slower to impress and faster to trust. Built by engineers who got tired of defending numbers they couldn’t trace.
No invented formulas.
Every number traces to a written specification. If there is no spec, there is no number.
Unknown is a valid answer.
When the inputs don’t support a result, VentScan says so. We don’t fill the gap with a plausible guess.
No silent defaults.
An assumption is recorded as an assumption. Nothing is decided behind your back.
The engineer decides.
AI drafts and explains. It never approves. Nothing changes without an explicit decision you can sign.
The decision must defend itself.
A Proof Pack holds the evidence, sealed and append-only, so the approval still stands up years later.
