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.

SCOPE
One-Liner
Git-based Markdown wiki orchestrator and federation layer — early-stage scaffold with intent, research, and specification groundwork; domain model not yet implemented.
Mode Of Operation
Close the gap between this file and INTENT.md by exploring the problem space
(research/), reviewing inbound demand (demand/), refining specifications
(spec/), and implementing through registered workplans (workplans/).
Learnings update both SCOPE and INTENT where necessary.
Current Status
| Layer | State |
|---|---|
| Code | Python package scaffold (src/shard_wiki/, smoke tests only) |
| Intent | INTENT.md established; authorization-in-core amendments drafted |
| Research | yawex prior art; c2 origins; federation concepts; wikiengines overview (research/260608-*/); XWiki/TWiki/Foswiki deep dives (research/260613-*/); Xanadu + ZigZag + Roam + Obsidian + Notion + Joplin + Logseq + local-first workspaces (Anytype/AFFiNE/AppFlowy) deep dives & shard-spectrum synthesis (research/260614-*/) |
| Demand | NetKingdom integration asks captured, not yet negotiated |
| Spec | Architecture blueprint drafted; UseCaseCatalog 65 UCs from research; PRD/TSD scaffolds |
| Work | SHARD-WP-0001 active (6 tasks); SHARD-WP-0002 active (16 tasks: T1–T10 federation + T11–T16 adapter contract) |
In Scope (today)
- Establishing repository documentation structure and specification groundwork.
- Federation design informed by yawex prior art (page resolution, namespaces, derived views, provenance, overlays).
- Authorization model design (delegated authentication, core authorization).
- Shard adapter contract and wiki page model (to be specified, then implemented).
- Git-backed coordination journal for information spaces.
- State Hub workplan registration and consistency sync.
Out Of Scope (today)
- A standalone wiki engine UI or rendering pipeline.
- Authentication, credential storage, or user directory implementation.
- Hard-coded editorial, sync, or conflict-resolution policy.
- Generic file mirroring independent of wiki-page semantics.
- Production deployment, multi-tenant operations, or enterprise IAM rollout.
Boundary Rule
shard-wiki orchestrates wiki-shaped content across heterogeneous shards. It
provides mechanisms (federation, projection, overlay, patching, reconciliation);
policy (canonical source, conflict preference, access rules) remains explicit and
configurable. Identity comes from pluggable providers; authorization decisions
live in core.
Current Planning
Design work is tracked in workplans/SHARD-WP-0001-yawex-requirements.md
(yawex-derived resolution, namespaces, overlays) and
workplans/SHARD-WP-0002-federation-architecture.md (federation architecture,
decisions, tradeoffs). Specification outputs land in spec/. Inbound
integration asks remain in demand/ until reviewed and promoted into spec or
workplans.
