Risk context, not investment advice. These records explain mechanisms and state how firmly each link is established; they contain no prices, tickers, named securities, forecasts or recommendations.
How each step is gradedA step can never be graded more firmly than the step it depends on: a consequence cannot be better established than its cause. That rule is enforced when this site is built — a chain that broke it would fail the build rather than publish.
ConfirmedDocumented as having occurred, with sources.
Plausible exposureA mechanism Vigil assesses as likely; not documented as having occurred.
Unconfirmed scenarioNamed because it is worth watching. Not asserted.
The mechanisms6 transmission mechanisms in NATO Eastern Flank, each shown as its own stage sequence. The grade under each stage is that step’s, not the chain’s — the point of the strip is to show where a mechanism stops being documented.

Allies committed to five per cent of GDP by 2035, but the constraint on this theatre is not money — it is the interval between a contract, a plant and a delivered round.

Evidence and grading
Basis
How firmly one STEP is established — documented, assessed as likely, or named but unverified. It is a property of the link, not of the chain.
Confidence
How well established Vigil considers this assessment to be. It is not a measure of how severe the situation is.
