We propose the Living Habitat Sleeve — an optional, staged retrofit that adds habitat capacity to the bio-synthetic space elevator of the FCLT paper series (P74, P81, P94–P106). The sleeve consists of a triple-layer helical maglev guideway wrapped around a proven Stage 1 tether, carrying modular habitat pods that draw wireless power from the Phoenix-C Orbital Collector (P106). The guideway is mechanically decoupled from the tether via non-contact maglev, ensuring that the baseline tether-and-climber transport system remains fully functional regardless of whether the sleeve is fitted. We register four falsifiable conjectures (PHS-1 through PHS-4) relating the sleeve geometry and energy-transfer characteristics to φ-scaling ratios consistent with FCLT’s depth-2 recursive framework. No numerical result is claimed; every φ-relationship is a pre-registered conjecture to be evaluated once the enabling hardware is built. This is a concept and architecture paper: the system does not exist, and the paper’s purpose is to specify a buildable target and a falsification path in advance of construction.
