# PromptVault Core Merge Alpha

This build keeps the existing PromptVault product UI/features and replaces the full-library architecture underneath Explore with PromptVault Core.

## Corpus architecture
- 5,000 stable prompt families
- 50,000 total model/audience variants
- 10 variants per family
- 50 lazy family shards (100 families per shard)
- stable IDs: `pvf-xxxxx` for families and existing `pv-xxxxx` for variants
- precomputed inverted search index
- full prompt bodies are fetched only when a family is opened

## New working local intelligence
- Prompt DNA view
- Model compatibility estimates (clearly labelled as estimates, not generation proof)
- Model Translator
- Prompt Doctor
- Failure Fix
- stable family and variant saving

## Important verification boundary
The 50K corpus is under PV Structural Review.
`PV Verified` remains reserved for prompts with approved generated-output evidence.

## Preserved
- Existing PromptVault app shell and feature set
- V27 Explore routing fix
- V23 no-dead-tap protection
- V24 live-services scaffolding
- Netlify/PWA setup
- Vantra Studios branding
