Detailed Description

Phase A1b body — LEGACY CSTR water-age mirror.

Formula provenance, line by line, is the pollutant path in QualityRouting.cpp: accumulateLinkLoads (rate convention q·value), mixAtNodes ((c_old·v_old + mass_in)/(v_old + v_in) with the c_max clamp), updateLinkQuality (STEADY / no-flow / zero-volume / volume-balance branches with the DW q_in correction). Deliberate differences, both documented in the header: no evaporation factor (plan §8 — evaporation leaves the mean age unchanged) and no decay (age has none).
