Occupies the point the other modern tools leave empty: block-graph semantics (UUID-addressable, embeddable, queryable blocks) stored as plain Markdown/Org files on disk, with a DataScript graph derived from the files (files canonical, index derived). The bridge between Roam (block-DB) and Obsidian (file-over-app). Headline finding: Logseq resolves the addressing-spectrum tension — block-level addressing that is also git-diffable in-file text (id:: property) — and proves a file-backed shard can serve rich Datalog queries via a derived index. Also: file->SQLite "DB graph" migration is a live UC-43 (substrate swap under stable identity); whiteboards = non-Markdown content; dual-attachable (file-store direct with a Logseq format profile, or in-app plugin). Added UC-62 (attach block-graph-on-plain-files shard), UC-63 (serve structured queries over a file shard via a derived index shard-wiki builds — converse of UC-52); enriched UC-32/34/43/50/51/52/55. Catalog now 63 UCs. Architecture for SHARD-WP-0002 T11/T14/T16: Logseq format profile, derived-query-index capability, substrate-migration tolerance, in-file block addressing as the T16 span-address target.

Exploration results for the problem and solution space.
Each exploration uses a yymmdd- prefix on the markdown file or subdirectory
when multiple files or sources are involved. Findings here inform spec/ and
SCOPE.md; they do not directly authorize implementation until promoted.
