Gauging workbench
Proof & volume
Correct observed readings to the TTB reference condition or gauge directly from net weight.
Hydrometer → true proof (Table 1)
Weight gauge (Tables 4/5)
Mass-balance solver
Proofing cut
True contraction is calculated in mass space; final volume is never estimated by adding inputs.
Dilution — solve any direction
Canonical unit graph
Universal converter
Every display value projects from the same mass, ethanol, and solids state.
Universal converter
Type in any field. Everything else re-derives from canonical mass — round-trips are exact.
Formulation engine
Recipe lab
Scale forward to package count or solve backward from target proof and volume.
Recipe — forward scale
Reverse solve — hit a proof
Fixed lines above are held; solves spirit + water for the target.
Append-only operations
Production ledger
Post physical operations with frozen gauge values and server-generated correction reversals.
