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. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
