Detection: shadow-biosphere camouflage (anomalous-biochemistry screen).
hypothesisdetection_strategyScientific Instrumentation & Sensor Data
Blend into the biosphere as engineered biology with subtly non-terrestrial biochemistry; detect via screens for mirror chirality, non-standard genetic codes, or off-baseline isotope ratios.
Relaxes the assumption an alien agent is non-biological. Convergent biochemistry + panspermia-style seeding are allowed; metagenomics assumes LUCA descent, so a mirror-handed/non-standard lineage is invisible to standard pipelines. HYPOTHESIS.
