# ProSurvey Apps™ Ecosystem

An offline-first mobile survey, snagging, and structural compliance software suite for RICS surveyors, housing inspectors, and damp specialist professionals.

## Overview
ProSurvey Apps™ is a professional ecosystem designed to reduce paperwork and administrative overhead for property professionals. Utilizing a native mobile runtime with cross-platform synchronization, the system allows surveyors to log data, capture media, and compile fully formatted, client-ready reports directly from the field without an internet connection.

## Core Architecture
- **Offline-First Synchronization:** Powered by native SQLite engines operating via a Capacitor cross-platform bridge. Local state synchronizes securely with Cloud Firestore once a network becomes available.
- **Embedded AI Report Generation (Bring Your Own Key):** Supports BOTH **Google Gemini** AND **OpenAI / ChatGPT** via a bring-your-own API key model for checklist auto-completion, structural hazard triage, and narrative standard-clause synthesis. The surveyor chooses the provider and reviews all AI wording before export.
- **Client-Side PDF Compiler:** High-performance, memory-optimized custom vector engine generates multi-page reports with consistent visual layouts, margin limits, auto-calculating tables, and image grids directly on the device.

## Global Housing & Habitability Standards
- **UK Renters' Rights Act 2025** (Royal Assent 27 October 2025; main provisions from 1 May 2026): abolishes Section 21 no-fault evictions, introduces a Decent Homes Standard for the private rented sector, and extends Awaab's Law (enforceable damp & mould / hazard repair timeframes) to private rentals.
- **New Zealand Healthy Homes Standards** (mandatory for all private rentals since 1 July 2025): heating, insulation, ventilation, moisture ingress & drainage, draught stopping.
- **General:** minimum-standards / habitability regimes for rented and residential property also exist across the US, Australia, Ireland, Canada and other jurisdictions. The suite is designed to support property and damp documentation under such regimes generally.
