Split device sync into per-domain slots with bounded, dirty-only publishes

2026-08-02T01:08:58Z

One monolithic snapshot per device outgrew a vanilla relay's 64KB event cap the moment real payment traffic arrived, and sync silently died. Snapshots now fragment into per-domain replaceable events (core wallet, ark, nwc — an extension claims a domain by naming it), published under a new ':x:' d-tag marker that pre-split clients don't match, so they can never mistake a fragment for a full snapshot. Only domains whose content changed republish, a refused publish retries on the next save instead of being marked done, and readers apply full-snapshot semantics only to core-carrying events. The ark projection also caps its history: spent stubs at 200, done actions at 50 — the event size is bounded for life, no special relay rules required. Co-Authored-By: Claude Fable 5
