const sahPoolDigestV2Flag: 128 = SQLITE_OPEN_MEMORY;

Defined in: packages/sqlite-wasm/src/SahPool.ts:1292

The flag that marks a header digest as version 2.

Opfs-sahpool before SQLite 3.50 computed every digest as [0, 0] because of an overflow. The fix repurposed SQLITE_OPEN_MEMORY, which never reaches a VFS, to mark headers written with the fixed digest, so older headers stay valid.
