Case contract

Types (trimmed, case-insensitive) instant, active dry, fresh with grams per 1 g instant: 1, 5/4, 3. Unknown -> "error: yeast type". grams = amount/ratio[from]*ratio[to], printed half-up to 0.1 (float). tsp: None for fresh; else grams/3.1 in quarter teaspoons half-up: 0 -> "less than 1/4", <4 quarters -> "q/4", whole -> "n", else "n q/4" (quarters not reduced). bloom is True only when converting to active dry.

Why this case matters

Bakers substitute yeast forms and need both weight and spoon measures.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
regression: whole teaspoon carry	`{"bloom": false, "grams": 3.2, "tsp": "4/4"}`	`{"bloom": false, "grams": 3.2, "tsp": "1"}`	Failed
