SZL Atelier

A governed artifact constellation for the SZL Holdings public estate.

Atelier presents source ownership, declared Hub identity, controlled-file commitments, and bounded public provider evidence. It does not execute models, mutate Hugging Face, copy source authority, or turn a declared artifact into a runtime-success claim.

Evidence contract

SOURCE_PR
!= MERGED
!= HUB_PUBLISHED
!= RUNTIME_READY
!= EXACT_READBACK_VERIFIED

The running application exposes:

• /healthz
• /readyz
• /api/source
• /api/catalog
• /api/catalog/{kind}/{slug}

Public Hugging Face metadata readback is opt-in and restricted to curated SZLHOLDINGS/... identities. Redirects, arbitrary hosts, arbitrary paths, oversized responses, unsupported artifact kinds, malformed slugs, and mutation methods fail closed.

Source authority remains in the linked GitHub repositories. SZL Constellation composes estate navigation; Atelier composes artifact evidence.
