The closest existing engine to shard-wiki's own design: DB-canonical (Postgres/MySQL/SQLite) but with a pluggable storage-module abstraction that bidirectionally syncs clean Markdown (+ YAML frontmatter) to Git (also FS/S3/Azure), each provider acting as backup or source of truth. Two big findings: (1) the storage-module interface is concrete adapter-contract prior art alongside Foswiki::Store, and the closer one (medium = Markdown in Git); (2) the engine-maintained bidirectional Git mirror is the ideal file-store attach (clean MD + git history) and, being bidirectional, makes git commit a write path (overlay/patch as a commit, no API). Also GraphQL API (introspection = capability discovery; selective fields = efficient projection) and authn-delegated auth modules + path-based rule ACL. Added UC-68 (engine-maintained bidirectional Git mirror, write-by-commit), UC-69 (typed/introspectable API for schema discovery + selective projection); enriched UC-06/36/38/40/42/57. Catalog now 69 UCs. Architecture for SHARD-WP-0002 T11/T14: storage-module abstraction as 2nd adapter-contract prior art, engine-maintained Git mirror as attach+write surface, GraphQL introspection for capability discovery.

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.
