0.3.2: the bundled engine is PostgreSQL 18.6 (PGlite 0.5.13), not 16 — the workbench now shows the version the engine reports. Progress is stored through the host plugin storage (host.storage) instead of localStorage, which throws in the sandbox's opaque origin, with a visible session-only fallback. The package now ships LICENSE and THIRD_PARTY_NOTICES.md (PGlite Apache-2.0, PostgreSQL License, MIT question bank); engines.dbx is 0.6.19, the first host release with host.storage. A WebAssembly preflight explains in Chinese when the host sandbox blocks wasm. Local-only: no connection, no network.
