Evidence
One piece of the reasoning behind a Finding - the "how do you know?" a reader can check.
Parameters
label
What was measured, e.g. "Dependents".
value
The measurement, already formatted for display, e.g. "24 modules (55% of the project)".
howObtained
Where the number came from. An evidence list mixing tiers is normal - a finding often combines an observed fact with a computed one - which is exactly why each item carries its own tier rather than the finding carrying one for all of them.
