who else was there?

the crossings tab reveals people documented in the same place, in the same period. the fabric of paths that brush past each other through history.

who else was in paris in 1776?
2 presences overlap, each one sourced. but be careful…
correlation ≠ meeting. two presences in the same place don't prove they met.

zurich · 1916
Two historical figures cross paths on a Zurich street without recognizing each other, a presence pin above each of their heads
einstein and lenin lived in zurich at the same time. no source says they met, and neither does Quo Fuit.

a fact is never a guess.

field-notebook.txt

most tools blur what they know with what they guess.

Quo Fuit draws a clean line: a documented fact is never presented as a guess, and a guess never as a fact.

every presence shown carries its level of evidence, and traces back to its source in one click. the absence of a source is not a hypothesis: it is an absence.

documented fact

a person, a place, a date, indexed by a verifiable source. certain · sourced

correlation

two presences that overlap. a clue, never proof of a meeting. flagged as such

hypothesis

a possible deduction, labeled with its confidence, never slipped in among the facts. uncertain · shown

where does the data come from?

offline wikipedia (44 gb), a gazetteer of 1.33 million places, and public-domain biographies. everything is on your machine, nothing leaves.

can an extracted fact be wrong?

yes, and that's why every fact passes through a cascade of deterministic rules then a local ai judge. whatever fails is hidden and marked « disputed », never presented as true.

is a co-presence a meeting?

no. two documented presences in the same place in the same period are a correlation. Quo Fuit will never say « they met » without a source.
