+# Effect Drizzle SQLite Adapter
+
+This subtree is an upstream-derived Drizzle ORM fork adapted to run SQLite query
+builders over Effect's generic `SqlClient`. It is maintained source, not
+generated output.
+
+## Provenance
+
+The implementation is derived from Drizzle ORM's Effect SQLite driver/session,
+SQLite Effect query builders, and shared query-builder utilities. The
+corresponding upstream source families are `drizzle-orm/src/effect-sqlite`,
+`drizzle-orm/src/sqlite-core`, and `drizzle-orm/src/utils.ts`.
+
+The exact upstream revision originally copied into this repository is unknown.
+The currently pinned `drizzle-orm` version is a compatibility dependency, not
+copy provenance.
+
+## Local Boundary
+
+The supported local entrypoint is `@opencode-ai/core/database/drizzle`, exposed
+as the `EffectDrizzleSqlite` namespace. OpenCode's database service consumes that
+facade from `database/database.ts`.
+
+Material local adaptations include:
+
+- a runtime-independent driver over Effect's generic `SqlClient`
+- local cache, mapping, and runtime-inspection helpers
+- suppressed statement tracing beneath the database operation boundary
+- explicit SQLite transactions and savepoints
+- native transaction delegation for Durable Object SQLite
+- deliberate query-builder variance annotations
+
+Preserve these adaptations when comparing or synchronizing upstream code.
+Focused regression coverage is in `test/database-drizzle.test.ts` and
+`test/sqlite-workerd.test.ts`.
