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.
