Reference: Tom Cucuzza, The Secret of Bulk Fermentation (The Sourdough Journey). Tartine-style formula: 90% bread flour, 10% whole wheat, 75% water, 20% starter, 2% salt. Bulk starts at starter addition; shaped cold proof is 12-16 hours near 3°C (37°F). These are method-specific checkpoints, not universal targets.
