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contribution receipts, including withdrawn tombstones; both are written through an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.

Logging must never depend on AI availability, and an unsaved entry must not
disappear when the user navigates away mid-log.
- add src/vision-readiness.js so the photo flow consumes one readiness contract
- when the worker is offline/disabled/unknown, offer no AI action and no
analysis-consent prompt, and keep manual Bristol entry one action away
- add src/draft.js and make the draft own the photo so a chosen photo and
entered context survive a recoverable close or navigation, with a visible
kept-draft summary and an explicit start over
- drafts stay in session memory only: a photo awaiting consent is never
persisted, and reload starts clean
- service worker now refuses to cache image bodies in addition to analysis
requests and no-store responses
- tests: 2 new unit files, 3 service-worker privacy assertions (1 hold-out),
1 browser acceptance file, release-demo and CI/package assertions
- release demo now visibly replays the vision-offline pass and the retained
draft with synthetic data and an in-script assertion
