Nath Darsana: Aerospace-Grade VSOP87 Astrodynamical Computation Engine, Deterministic WASM Ephemerides, and Multi-Varga Agentic RAG Synthesis

We present the architectural and mathematical framework of Nath Darsana, a distributed, edge-computed astrodynamical engine engineered for sub-arcsecond aerospace ephemeris generation, continuous-to-discrete phase-space quantization (Varga / Dasha boundary evaluation), and multi-agent Sanskrit exegesis. Currently deployed and processing live production queries as an operational applet on https://bhutadamarasena.com, Nath Darsana serves as the deterministic celestial oracle supplementing our flight-qualified autonomous navigation metrics (Pillar V: Applied Aerospace V10.0, [2]). By shifting high-precision celestial mechanics away from monolithic servers to the extreme network edge, we hardware-certify two core applied computational theorems: Aerospace-Grade VSOP87 WebAssembly (WASM) Compilation (THM-NATH-V1-01, Section 2): Compiles the rigorous analytical VSOP87 continuous orbital series into zero-allocation WASM edge binaries. By natively supporting light-travel time corrections and heliocentric-to-geocentric apparent coordinate transformations, the engine achieves microsecond-level calculation of planetary bounds with rocket-level precision (< 1'' accuracy over 4,000 years), processing batch loads of N = 50,000 concurrent state vectors without dynamic heap allocation failures. Phase-Space Quantization & Multi-Varga Agentic RAG Synthesis (THM-NATH-V1-02, Section 4): Maps continuous aerospace ephemeris state vectors into deterministic, discrete astrological matrices (Bitwise Ashtakavarga and Dasha progressions). It then bridges these O(1) payloads with a vector-embedded classical corpus (Brihat Parashara Hora Shastra, Phaladeepika) deployed on Cloudflare D1/Drizzle, utilizing direct function-routed LLM layers (Gemini 2.5 Flash) for strictly bounded semantic exegesis with zero astronomical hallucinations.
