Sources

The source decides what can be treated as fact. Every source belongs to one tier, and each tier has its own weight of proof.

The list is fixed in the model configuration. Subdomains count at their parent domain's tier (for example yle.fi/news is Tier B). A source that is not on the list cannot support the reading.

Tier A: Finnish authorities

One Tier A source is enough to establish any fact.

21 domains:

puolustusvoimat.fi
defmin.fi
raja.fi
valtioneuvosto.fi
intermin.fi
presidentti.fi
um.fi
finlandabroad.fi
supo.fi
poliisi.fi
traficom.fi
fintraffic.fi
turvallisuustutkinta.fi
kyberturvallisuuskeskus.fi
fingrid.fi
gasgrid.fi
finlex.fi
eduskunta.fi
huoltovarmuuskeskus.fi
tuomioistuimet.fi
112.fi

Tier B: established news media, allies and international bodies

Serious events (severity × magnitude 55 or more) and state changes need two independent Tier B sources if there is no Tier A source.

Tier C: data and research sources

Sufficient on its own only for less serious events; serious events and state changes need Tier A or B sources.

7 domains:

gpsjam.org
gdeltproject.org
ecb.europa.eu
suomenpankki.fi
ucdp.uu.se

fred.stlouisfed.org

Russian official sources

Prove only what Russia said (statement types A1, A2, A3, A6, A7 and A9), never what happened. For statements they count as Tier B.

8 domains:

kremlin.ru
mid.ru
tass.com
tass.ru
ria.ru
government.ru
mil.ru
scrf.gov.ru

Other sources (Tier D)

Social media, Telegram channels, forums and anonymous OSINT accounts are only leads. They cannot support the reading.

How sources are used

Evidence must be at most 10 days old at run time, and its publication time may not be in the future.
A domain counts only once: two Yle stories are not two independent sources.
An event's "known" moment is the publication time of its earliest evidence. The real-time reading never uses information before it was published.

Protection against manipulation

The index measures activity whose authors have a reason to try to influence it. Therefore

fetched text is given to the AI only as quoted material, and the model has no tools with which it could change anything;
the source list is closed, and every quote is checked against the fetched page;
Russian official sources prove only what Russia said – not what happened;
every significant rise passes through a person.
