## Core Shipped Systems

### 1. Tender-Trace (CPPP Watchdog)
A civic-transparency watchdog analyzing ₹-crore Indian public procurement. Ingests over 4.5 million Central Public Procurement Portal (CPPP) contract award records, runs Herfindahl-Hirschman Index (HHI) market-concentration analytics and logistic-regression weighted Integrity Risk Index (IRI) models, preserves batch provenance via SHA-256 cryptographic hashes, and generates statutorily correct Section 6(1) Right to Information (RTI) dossiers addressed to official CPIOs. Powered by an autonomous Tri-Agent ingestion protocol (Protocol v2) and a Cloudflare Hyperdrive edge query proxy.

- Technologies: Next.js 16, React 19, TypeScript, Cloudflare Hyperdrive, Cloudflare Workers, Cloudflare R2, PostgreSQL / Supabase, SQLite, D3.js, Recharts, Python ETL.

### 2. DentalConnect OS (DCOS 2.0)
An enterprise-grade bi-temporal clinical operating system and dental lab cloud connecting chairside dental clinics with prosthetic milling centers. Built on PostgreSQL 17 with bi-temporal event sourcing (Valid Time vs. Transaction Time) and a SHA-256 Merkle ledger powering historical "Time-Travel Odontograms" for medicolegal defense. Integrates an interactive 32-tooth elliptical odontogram (FDI/Universal), chairside appointment scheduling and operatory telemetry HUD, a dedicated 3D CAD/CAM workstation with progressive WebGL LOD mesh pyramids (95% vertex reduction), occlusal clearance heatmaps, Catmull-Rom subgingival margin splines, and Exocad XML parsing. Fully ABDM (Ayushman Bharat Digital Mission) Milestone 1–3 compliant via the Fidelius sovereign cryptographic bridge (Curve25519 ECDH + AES-GCM-256) and HL7 FHIR R5. Covered by 3 filed Indian patent specifications. Master backend verified (33/33 tests passed, 100%).

### 3. Tark
A high-precision UPSC Civil Services and State PSC testing arena and policy intelligence system (51,000+ lines of TypeScript). Features a strict server-authoritative 2-hour Prelims Exam Hall simulation with keyboard hotkeys (`useExamKeyboard`), live OMR response grid, UPSC negative marking (+2.0 / -0.66), and Diagnostic Autopsy scorecards analyzing sectional accuracy, dynamic cutoff probability bands, pace velocity, sheet omission discipline, and blind-guessing risk ledgers. Includes the 25-Year UPSC PYQ Relational Vault (2001–2025) cataloging 4,156 authentic questions across 140 syllabus taxonomy nodes, an empirical Examiner Psyche analytics suite, a KaTeX-backed 25-year academic research observatory, and a deterministic Grounding Protocol (`verify.ts`) with sentence-level token matching, interactive `SourceAnchor` citations to official government releases (PIB, PRS Legislative, RBI), and an autonomous Contested-Claim Engine (`contested.ts`).

### 4. FASAL MIS
A monitoring and evaluation dashboard for a ₹2.16 crore farmer-livelihoods programme run by DEHAT and funded by the Oak Foundation. Tracks 1,300+ rural households across six programme areas in Bahraich District, UP, triangulating 28 conflicting source datasets. Features a transparent in-production Data Quality Audit documenting discrepancies, reproducible algorithmic corrections via seeded deterministic RNG, and a structured "Stories of Change" qualitative narrative module.
