adlee-was-taken	0b59b94a0b	test(core): populated-vault round-trip for backup	2026-04-27 22:34:36 -04:00
adlee-was-taken	08086b9a9e	feat(core): backup module — empty-vault round-trip ... pack_backup / unpack_backup ship the magic header, format version, Argon2id KDF, XChaCha20-Poly1305 AEAD, and zstd-compressed JSON envelope. Empty-vault round-trip is the foundation; later tasks add items, attachments, image, and git history.	2026-04-27 22:29:10 -04:00
