Paper 26.2 plugin speaking the stock MapSyncer client mod's protocol. Renders Xaero region zips from the world's region files, but only for chunks players have actually been sent (PlayerChunkLoadEvent), seeded once from InhabitedTime. Shared or per-player visibility, background render cycle, per-player streaming with hash/timestamp skipping, Gitea Actions release workflow. Vendors the MCA parser and Xaero writer from upstream MapSyncer (GPL-3.0), see NOTICE.md. Claude-Session: https://claude.ai/code/session_011FePLXwBsCGLTzaSkk1Z6V
