ADR-0111: SeaweedFS and client storage instead of MinIO

• Status: accepted
• Date: 2026-10-30
• French version: ../ADR-0111-stockage-client.md

Context

MinIO is AGPL-3.0; the kit imposes the client's storage.

Decision

Object storage is the client's (S3, Azure Blob, GCS adapters); SeaweedFS serves development; MinIO carries replacement: seaweedfs.

Consequences

Each capability (WORM, versioning) is detected and verified per storage profile.
