Detailed Description

Water-age tracking data (water age plan §1–§2, phase A1a).

Age is the reserved species __WATER_AGE__ (registry kind RESERVED_AGE): zero-order growth d(age)/dt = 1 in every water parcel, volume-weighted mixing everywhere water mixes. Internal unit is SECONDS (the config file speaks HOURS — ×3600 at parse). Per-source initial ages come from the waterage component's [WATER_AGE_SOURCES] (model.age, D-UT8): each QualitySolver loader contributes age_volume = q · age_source to its node, and the transport engine mixes it in exactly like a pollutant load.

A1a scope: the age species rides the EULERIAN_ARD mesh; the LEGACY CSTR age mirror is phase A1b (warned until then); watershed/LID/GW age states are A3/A4.
