v0.275.0: a backup's data and its version travel together (R-696, 07 §6.6, D4 option A); R-695, R-691, R-694

The unit's data files are stamped with the versions that wrote them; the capture keeps the definition the data belongs to; a restore never starts data under another version's definition (unit restores refuse a mismatch; the off-site restore writes the snapshot's definition); every tier's time is its data's; the conversion-copy release needs a dump on the new engine. File-browser sync single-flight + no empty kept folder (R-695); the kept view joins the folder's owning group, language switch resyncs (R-691); a restore-generated login is not shown as the password (R-694). Red-proofs in felhom.eu/documentation/audits/version-travel-2026-09-26/.
