A high answer here is a starting point, not a verdict — follow it with `market_profile` for the curator's cut and whether the money can be withdrawn, and `yield_history` for whether the rate has held.",

Each signal carries its raw value and its sub-score, and `method.weights` gives the weighting, so the score can be recomputed. A signal lacking data reports score null and is excluded from the weighting rather than guessed at. Pair with `yield_history` for an unusually high rate. Describes what has happened, not what will.",
