A backup is the person's own record and has to keep working as the AI fields evolve. - Export stamps schema version 2 and carries the confirmed logs plus the training contribution receipts, including withdrawn tombstones; both are written through an allowlist so unknown keys and credentials never leave the device. - Import accepts version 1 and 2. A version 1 file is upgraded, the notice names the version it came from, and entries that predate provenance stay null instead of being given a source they never recorded. - A file from a newer Timmy is refused with an update instruction, malformed, oversized and over-limit files fail closed, and a refused import leaves the ledger unchanged. - A log saved from a confirmed or corrected AI suggestion records its provenance (source, suggested visible fields, model, confirmedAt) and the entry sheet states it. - Service worker shell cache v5 -> v6 so installed clients actually receive the change. Evidence: tests/portability.test.js (7 unit cases), tests/portability.acceptance.mjs (real browser: v1 upgrade, future refusal with unchanged ledger, provenance recorded, export v2, round trip), release demo scenes with on-camera caption proof, and the release builder gate portable_backup_restore.
