# FETCH Packetizer (Stub)

This directory contains the initial FETCH packetizer stub.

## Current behavior
- Produces schema-conforming Research Packets **without** network retrieval.
- Intended for testing:
  - schemas
  - validators
  - quarantine behavior
  - CORE consumption

## Why no network yet?
Network retrieval must be implemented **only** with:
- managed egress proxy
- allowlisted domains
- strict normalization
- deterministic validation + quarantine

The stub avoids accidentally violating the FETCH policy.

## Usage
From repo root:

```sh
chmod +x fetch/packetizer/packetize_stub.py
export PYTHONPATH="$(pwd)"
