deprot-core

The pure, zero-I/O heart of deprot. Everything here is deterministic: given the same [Facts] and the same reference time, [score] always returns the same [Score]. That is what makes the scoring engine fully unit-testable and replayable from cached fixtures — no network, no clock, no filesystem reach into this crate.

The data pipeline is: an ecosystem manifest yields [Dependency] values, the collector turns each one into [Facts], and this crate turns [Facts] into a [Score] (a 0–100 value, a letter [Grade], a [Tier] verdict, and the list of [Signal]s that explain it).
