Module compressed_vfs 

Schema-neutral compressed SQLite VFS.

The facade defines the shared container model. Codec policy, on-disk format, container mutation, file callbacks, and VFS registration are implemented in focused modules.

Encrypted containers use authenticated format v2. Header fields, complete chunk entries, physical record locations, and commit records are bound to a per-file identity. A valid whole-file snapshot rollback remains outside the format’s threat boundary because it requires an external freshness anchor.
