Walks the local store and maps it onto the cloud object model per the design doc: captures, generations (+ version wavs), profiles (+ samples, avatar), and the settings singletons. Records carry the full row (paths storage-relative so restores re-anchor under the destination data dir); audio travels as per-asset ciphertext blobs. Envelopes are randomized, so a new cloud_sync_state table remembers both the plaintext fingerprint (did content actually change?) and the ciphertext hash the server holds (re-declare unchanged blobs without re-encrypting or re-uploading). updated_at is excluded from fingerprints - its onupdate trigger fires as a side effect of applying pulls and would bounce synced objects otherwise. Push runs before pull; conflicts are last-writer-wins per object. Own pushes echoing back through the feed are recognized by ciphertext hash and skipped. Tests simulate two machines (own DB, data dir, keychain) syncing through an in-process fake cloud: full backup/restore with byte-identical audio, incremental edit (only the record blob re-uploads), delete propagation, LWW convergence, and the blindness check that server storage only ever holds VBX1 envelopes.
