//! The §11 **pending solidity** (bl-915e): a send is shown in-memory in faded
//! colour, brightening when it is actually locked in as a statement. Split from the sibling badge corpus at
//! §12's budget — the badge tests ask what a fact *looks* like, this one asks
//! how much of it there is.

use crate::transcript::Tone;

/// Two facts, and both matter: `Weak` really fades, and every other tone is a
/// fact the derivation already asserts, so it paints solid — a mapping that
/// dimmed anything else would fade rows nobody sent.
