# Keptured Technologies — Digital Legacy & Memorial Infrastructure

> Keptured (https://keptured.com) bridges physical monument engineering with encrypted digital legacy vaults, connecting gravesites and memorials to permanent family archives via laser-etched QR plaques, WebXR spatial ribbons, and zero-PII cryptographic attestations.

## Overview & Architecture

Keptured Technologies (Pty) Ltd. is a digital legacy and memorial preservation platform designed for families, funeral homes, stone masons, and life insurance burial societies. The platform anchors digital biographical archives directly to physical memorial locations through durable hardware and decentralized cryptographic proofs.

### Core Ecosystem Pillars

1. **Pillar 1: Living Story & Biographies**
   - Media archiving: high-resolution photos, audio voice notes, letters, academic works, and oral histories.
   - AI Storyteller & Animation Studio: transforms manuscripts and notes into animated narrative documentaries (1080p / 4K).
   - TikTok-style vertical presentation reel on public memorial viewports (`/view/:id`).

2. **Pillar 2: Memorial Site & Gravesite Radar**
   - Geolocation anchoring: sub-meter GPS coordinates mapped to physical cemetery plots.
   - Radar Map (`/explore`): Leaflet-based radar discovering nearby memorials within 50km geofence with optional PIN locks.
   - WebXR Spatial Ribbons: Three.js augmented reality projecting 3D floating memory ribbons directly over physical headstones via mobile camera viewports.

3. **Pillar 3: Guardian Network & Succession**
   - Quorum-based multi-guardian governance via WhatsApp (+27 78 188 0660).
   - Digital Executor emergency transfer and zero-knowledge deadbolt unlocking.
   - Family Splinter & Merge management: allows decentralized family branches to claim, splinter, or merge memorial sub-trees without compromising root ownership.

4. **Pillar 4: Privacy, Security & WORM Preservation**
   - Zero-PII verification: official death and estate documents are verified in volatile memory with Merkle tree proofs; zero raw identity bytes are written to persistent disk.
   - 10-Year WORM Storage Ledger: tamper-evident immutable Google Cloud Storage bucket (`gs://keptured-ac3f0-worm-vault-africa-south1`).
   - Post-quantum ML-DSA-3 and ML-KEM-768 telemetry for future-proof security.

## Physical Hardware & Stonemason Specifications

- **Laser Plaque Standard (TC-3.2)**: 120mm x 120mm 300 DPI print-ready vectors (1417 x 1417 px) with 4x 4mm corner mounting holes (8mm inset) and central 40mm x 40mm high-contrast QR matrix.
- **CNC Toolpaths**: Automated DXF/SVG vector generation for diamond-drag, laser-etching, and CNC rotary routing on black granite, bronze, and marine-grade stainless steel.
- **Engraver Order Portal (`/engraver-portal`)**: Dedicated portal for monument fabricators to download print-ready vector assets and dispatch tracking.

## Institutional Developer APIs (Track B)

- **Base URL**: `https://api.keptured.com/v1`
- **Authentication**: HMAC-SHA256 Bearer Token (`kp_live_...`) with 7-day dual-key rotation overlap.
- **Endpoints**:
  - `POST /v1/jobs/estimate`: calculate 3-tier story quote based on token and page count.
  - `POST /v1/jobs/create`: initialize AI animation synthesis and Paystack payment session.
  - `GET /v1/jobs/:jobId`: query render progress, storyboard chapters, and encryption keys.
- **Rate Limit**: 100 requests/minute via Upstash Redis.

## Eco-Legacy Initiative

Every Keptured digital vault permanently calculates and offsets its operational carbon footprint by sponsoring indigenous tree planting in South Africa (Wild Olive, Yellowwood, Spekboom, White Stinkwood).
