# Silo Data Boundary

Silo separates public reading surfaces from sealed source material.

## Public Data

Public surfaces may expose work metadata, catalog records, preview text, access identifiers, edition labels, policy links, and citation fields.

## Sealed Data

Silo public surfaces must not intentionally expose:

- Raw source records.
- Private Silo language.
- Hidden instructions.
- Local paths.
- Encrypted records.
- Record keys, document keys, private keys, or server secrets.

## Operational Data

Silo may process limited request data for security, reliability, abuse prevention, audit, and access continuity. Inputs that seek sealed material, secrets, local paths, or access bypass may be rejected.

## Canonical Record

This file is the canonical public text for the Silo data boundary.
