Technical Failure Modes & Moat Evaluation

Critical scaling chokepoints and defensibility moats.

Critical Path Bottlenecks

Thermal & Kinetic Stability
High Severity

Degradation observed at operational temperatures above 45°C under continuous duty cycles.

Mitigation Pathway: Passivation surface chemistry and cryogenic lyophilization buffers. (In Progress (60% resolved))
Supply Chain Precursor Purity
Medium Severity

Reliance on single-source high-purity organometallic reagents creates inventory fragility.

Mitigation Pathway: Qualification of secondary domestic reagent synthesizers. (Identified)
Regulatory Standard Harmonization
High Severity

Lack of standardized ASTM/ISO assay protocols leads to cross-lab divergence in published yields.

Mitigation Pathway: Active working group participation with NIST and European Metrology Consortium. (Under Review)

Defensibility & Moat Verdict

• IP Defensibility: Strong Moat (Composition of Matter + Proprietary Bio-Informatics)
• Switching Barrier: Moderate (API / Droplet compatible)
