Zoological Vectors (Zo-Codes)
ATH
Birds, insects and animals leave more than mess — guano is corrosive and richly feeds biological growth, and wildlife ferries nutrients and organisms onto a building. The 'Zo-Codes' track these animal contributions, including the sentinel cases that carry a genuine health risk, so a clean accounts for where the contamination is really coming from.
The Zo-Codes classify faunal contamination of the built environment — the animal vectors that deposit, transport or directly damage architectural surfaces. They cover avian guano (a corrosive, nutrient-rich biological subsidy that accelerates colonisation and etches stone and metal), and the broader 'biological subsidy matrices' by which birds, mammals and insects move nutrients and organisms onto buildings. Within the COSMOS record each contaminant carries an organism code (F/A/L/MS/BX/Bc/Zo), an atmospheric vector (V-Code), a meteorological trigger (At-Code) and an intervention (P-Code), with a Forensic Tier (T1–T4) where T4 marks a sentinel species demanding mandatory action.
