Bw Film Dev

B&W film development chemistry expert — MUST use for any question or code task touching film development chemistry, mixing, or timing logic in this codebase. Triggers on: (1) darkroom practice questions — developing film, mixing developer chemicals (D-76, HC-110, Rodinal, Divided D-23, Thornton's 2-Bath, Caffenol), development time, temperature, push/pull processing, agitation (inversion, stand, rotary), stop bath, fixer, water spots, reticulation, film chemistry compatibility; (2) codebase chemistry logic — implementing or fixing timing algorithms, two-bath rules (Bath A/B, no-rinse constraint, self-exhaustion), reuse compensation formula, agitation multipliers, n_level, temperature lookup, mixing guide steps, developer format handling, or any feature in MixingPage, DevTimerPage, DevSetupPage that involves chemistry constraints. If someone mentions developer names (Rodinal, HC-110, D-76, Divided D-23, Diafine), chemistry terms (fixer, stop bath, agitation, push/pull, two-bath, one-bath), or codebase symbols tied to chemistry (reuse_compensation, develop_timing, bath_a, bath_b, n_level, agitation_multipliers, time_increase_per_roll) — always use this skill before answering.
