tegwick 3e0c05a2b3 research: local-first workspaces cohort deep dive (Anytype/AFFiNE/AppFlowy) — CRDT substrate; UC-64/65 
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.
