Readonlybasewhether the package is an R-core / base package
Readonlydeclaredthe raw declared version constraints
Readonlydeclaredthe combined, satisfiable declared range (inferredVersion), or undefined if none/contradictory
Readonlygetthe memoized function resolver used for the signature pass (shared so evidence reuses the decodes)
Readonlypreversions after the declared/transitive/base/date constraints but before the signature filter
Readonlysurvivorsversions after all constraints including signature-usage compatibility
Readonlytotalthe total number of versions the database carries for the package (the full history the candidates are drawn from)
Readonlyunsatisfiablewhether the declared + transitive constraints contradict each other (no version can satisfy them all)
the versions of a package before and after the signature-usage filter, plus the declared inputs used to build them
