Combined cohort memo for the three open-source local-first all-in-one workspaces, studied together because they share the trait none of the prior eleven systems had: the store is a CRDT (Anytype any-sync, AFFiNE Yjs/y-octo, AppFlowy Yrs). The cohort thesis: CRDT changes the adapter math — the backend performs conflict-free merge itself (shard-wiki must not impose git/text merge; speak the CRDT via a replica or stay projection/overlay), history is a CRDT update log (supplement not git), and the attach surface is a replica or self-host sync endpoint, with Anytype adding P2P (no single endpoint) + E2EE (opaque). Added UC-64 (CRDT-synced shard with native merge), UC-65 (P2P/decentralized shard, no single canonical endpoint); enriched UC-36/47/48/51/55/57/58/61. Catalog now 65 UCs. Architecture for SHARD-WP-0002 T11/T14: merge-model capability (proposed 13th spectrum: none/git/native-CRDT), CRDT-replica substrate + P2P/no-central-endpoint attach mode, endpoint-model capability, MCP as an integration surface. Boundary: CRDT local-first candidate shards — attach a replica/projection as pages, respect native merge, never re-drive their sync; not substrates and not the federation layer.
