From cde57423e04812fe2c939fdf983e3b45a77fd82d Mon Sep 17 00:00:00 2001 From: Christophe Besson Date: Wed, 16 Sep 2026 11:17:46 +0200 Subject: mnp 3.1: per-account blobs the node cannot read MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit One row per playlist plus a manifest, so starring a track rewrites that playlist rather than the whole collection. blob_enc is a BLOB, not base64 TEXT: these run to hundreds of kilobytes. user_id comes from the session and never from the message; kind is validated against a pattern; every cap refuses with a stated reason rather than truncating. Additive, so MNP_MIN_SUPPORTED does not move — a 3.0 node answers "unknown message type" and the client writes to the next one it reaches.
