# Phase 0 – Generic Platform Foundation

This package introduces the new platform namespace `at.procon.dip` without breaking the existing
TED runtime under `at.procon.ted`.

## New project identity
- Project name: **Procon Document Intelligence Platform**
- Short name: **DIP**
- Base namespace: `at.procon.dip`

## Intent
Phase 0 is intentionally light-weight. It defines the canonical vocabulary and SPI contracts that
later phases will implement incrementally:
- generic document root model
- optional owner tenant + explicit document visibility/access model
- ingestion adapters
- type detection
- extraction
- text normalization
- vectorization provider abstraction
- generic search scope

## Access model
Documents are no longer assumed to be always tenant-owned.

Examples:
- public TED notice -> `ownerTenant = null`, `visibility = PUBLIC`
- tenant-owned private document -> `ownerTenant = tenantA`, `visibility = TENANT`

This keeps ownership and access semantics separate from the beginning of the generalized model.

## Compatibility
The new Spring Boot entry point is `at.procon.dip.DocumentIntelligencePlatformApplication` and it
explicitly scans the legacy TED packages so the current runtime remains operational while future
phases migrate modules gradually.


## Phase 1 note
The additive `DOC` schema and generic persistence services are introduced in `README_PHASE1.md`.
