GeoNum is a drift-tracked, zone-tessellated arithmetic that attaches a trust verdict to every computation, reporting how many digits actually survived the arithmetic instead of returning a silent IEEE-754 answer. It runs in your browser with no install, deterministically, so you can see the conditioning of a result the moment it is produced. GDBS is a bridge to HPC, not a surrogate: the per-result verdict lets you check numerical health before committing a run to a cluster.
GeoNum returns one of six levels - EXACT / PRECISE / VALID / DEGRADED / UNRELIABLE / CANCELLED - on every computation. Validated on the Hawking-temperature chain to 0.27% across 60 orders of magnitude, and used as the per-result badge across the engines.
GeoNum is a drift-tracked, zone-tessellated arithmetic. Alongside each f64 value it carries a drift compartment that tracks accumulated loss of significance through the arithmetic, then maps that drift onto a six-level trust verdict: EXACT, PRECISE, VALID, DEGRADED, UNRELIABLE, CANCELLED. The verdict is surfaced as a per-result badge across the engines, so each computation reports how many digits actually survived rather than only the IEEE-754 number. The mechanism was validated end to end on the Hawking-temperature chain, where it held 0.27% across 60 orders of magnitude.
GeoNum is a conditioning-based uncertainty signal, not extra precision. It flags loss of significance that the IEEE-754 result hides, but it does not change the f64 value itself. The verdict tells you how much to trust the number you already have; it does not give you more bits.
The verdict is deterministic and runs in your browser.
