Windows has carried SQLite as winsqlite3.dll since Windows 10, and programs such as winget keep their package index in it. scripts/provision-sqlite.py builds the pinned public-domain amalgamation (3.54.1, SHA3-256 checked) with MinGW, exporting the unsuffixed sqlite3_* interface; the runtime places it in the system directory like its other components. Only the 64-bit library for now: Windows' 32-bit winsqlite3 uses the standard calling convention for its interface and callbacks, which the published amalgamation does not declare. Assisted-by: Claude Code:claude-opus-5-5 AI-Scope: provisioning script, CMake wiring, license records and the sqlite_client test
