tegwick e00c160a43 research: Joplin deep dive (SQLite-local/Markdown-on-sync, interchange-format attach, E2EE content opacity); UC-60/61
Architecturally distinct from the Obsidian/Roam/Notion trio: content is
Markdown, the local store is SQLite, and the sync representation is a
folder of per-item Markdown+metadata files on a backend of choice
(filesystem, WebDAV, Nextcloud, Dropbox, OneDrive, S3, Joplin
Server/Cloud). Two new findings: (1) attach the sync/interchange mirror,
not the app or the SQLite store, offline and app-independent, landing on
INTENT's WebDAV/Nextcloud/S3 backends (UC-60, distinct from native
on-disk store UC-40 and app-files UC-53); (2) E2EE => content opacity, a
proposed twelfth capability spectrum for encrypted-at-rest shards (UC-61).
Also: Joplin is the file-sync-daemon boundary case (attach the mirror as
pages, never re-sync); store-minted page-level :/id links (addressing
spectrum middle); dual surface (plugin host + local Data API on
localhost:41184). Enriched UC-31/36/38/40/51/55. Catalog now 61 UCs.
Architecture for SHARD-WP-0002 T11/T14: interchange-format attach,
content-opacity field, local-REST sub-mode, format-aware file-store
profiles.

# 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 deep dives & shard-spectrum synthesis (`research/260614-*/`) |
| Demand | NetKingdom integration asks captured, not yet negotiated |
| Spec | Architecture blueprint drafted; UseCaseCatalog 61 UCs from research; PRD/TSD scaffolds |
| Work | `SHARD-WP-0001` active (6 tasks); `SHARD-WP-0002` active (16 tasks: T1T10 federation + T11T16 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.
