tegwick 64796f7b3a research: Notion deep dive (closed block-DB SaaS, external REST API only, database-as-pages); UC-57/58/59

The closed/hosted/schema-rich extreme: everything is a block (UUID id,
type, properties, ordered child content, single parent), pages are blocks
and database rows are pages with a schema, Postgres-backed hosted SaaS.
Databases add typed properties + relations + rollups + formulas across
many views = the apex of wiki-page-as-structured-record. Extension model
has no in-app plugin runtime; the only extensibility is the external REST
API (+ webhooks 2026) inside a tight envelope (~3 rps, eventual
consistency, recursive child fetch, scoped/revocable per-page grants).
Adds the third attachment mode (external-API-only) alongside file-store
(Obsidian/TWiki) and in-engine host (Roam/XWiki); Notion enforces no
silent remote mutation via scoped grants. Added UC-57 (attach closed
external-API-only shard w/ operational envelope + scoped grant), UC-58
(typed database w/ schema+relations+views, no flattening), UC-59
(lossy-aware translation w/ fidelity report); enriched
UC-31/34/36/39/50/51/52/54/56. Boundary: one external-API candidate shard,
best as projection/mirror/overlay/backup, not a substrate 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 deep dives (`research/260614-*/`)
Demand	NetKingdom integration asks captured, not yet negotiated
Spec	Architecture blueprint drafted; UseCaseCatalog 59 UCs from research; PRD/TSD scaffolds
Work	`SHARD-WP-0001` active (6 tasks); `SHARD-WP-0002` active (10 tasks)

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.
