- Anchor the message list to the bottom (`reverse: true`) so new messages
stay in view instead of landing below the fold.
- Move chat history from the OS keystore (O(n²) JSON blob, silent 200-msg
cap) to a separate encrypted Drift/SQLCipher DB (`ChatDatabase`):
indexed append, uncapped history, dedup as a unique-key invariant. It's
an ephemeral per-device cache, isolated from the inventory schema, its
migrations, and its sync. No data migration (pre-release).
- Add day separators (Today/Yesterday/locale date) and a per-bubble time,
all via ICU (12/24h per locale; Localizations locale maps Asturian →
Spanish for intl date symbols).
- Add peer avatars (deterministic colour from the pubkey + name initial),
surface send failures that were previously silent, and make bubble text
selectable (addresses, links).
- New i18n keys in en/es/pt/ast; tests for grouping, formatting, avatars,
scroll anchoring, storage and send errors.

Reusing the backup snapshot for sync had two bugs that would bite real use:
1. Deletions didn't propagate. exportInventory() filters isDeleted=false
(user backups are tombstone-free by design) and the JSON codec dropped
isDeleted (omitted on encode, hardcoded false on decode) — so deleting a
variety on one device never reached the others. Now the codec round-trips
isDeleted (emitted only when true, so backups stay byte-identical and it's
backward compatible), and a new exportForSync() includes tombstones. The
importer already merges them LWW-correctly.
2. Photos bloated events. The snapshot embeds photo bytes as base64, so a
real inventory would blow past relay event-size limits and sync would
silently fail. exportForSync() omits attachments entirely (photos stay
device-local; media sync is a separate, deferred concern).
buildSnapshot() now uses exportForSync(); backups keep using exportInventory
(photos in, tombstones out) unchanged.
Tests: a deletion replicates as a tombstone; the sync snapshot carries no
photo bytes while a sealed backup still does.
Wires the encrypted sync transport into a working replication between one
identity's own devices, reusing the CRDT-ready model (HLC + tombstones +
LWW) the data model was built for.
- SocialSession gains a 5th interface, sync, over the shared connection,
built with a per-install deviceId + the app's inventory namespace.
- DeviceIdStore: a stable random per-install id in the keystore — distinct
from the seed-derived CRDT node id, which is IDENTICAL across a user's
devices (so it couldn't tell them apart / they'd clobber each other's
replaceable record).
- InventorySnapshotIO (implemented by ExportImportService): build/apply the
inventory as the SAME interchange JSON as backups but UNSEALED — the sync
transport does the encryption, so it must not double-seal. Apply = the
existing idempotent LWW importInventory.
- SyncService: on (re)connect publishes this device's snapshot + subscribes
to the others'; a local edit (debounced, off tableUpdates) republishes;
incoming snapshots merge idempotently; skips its own echo; a byte check
skips re-publishing an unchanged snapshot so the ping-pong converges.
Foreground only, like the inbox.
- DI/Bootstrap/switchSocialAccount wire and lifecycle it per identity.
Tests: DeviceIdStore, ExportImportService snapshot round-trip (unsealed +
idempotent), SyncService.handleRemote (applies others', skips own).
Follow-ups: deltas vs full-snapshot pushes; background sync; conflict UI.
Every feature (offers, messaging, trust, profile, the inbox listener) used
to open its OWN RelayPool via social.openSession — several sockets to the
same relays, more battery, and reconnection logic living only in the inbox
listener.
Add SocialConnection: ONE shared session per identity, lazily connected and
reused by all. It watches connectivity — dropping the session when the
network goes and reconnecting when it returns, announcing each change on a
sessions stream so the inbox listener re-subscribes automatically. Callers
get the session via connection.session() and never close it (the connection
owns its lifecycle); recreated/disposed on an identity switch.
- InboxService now consumes the shared connection (subscribes on its
sessions stream) instead of owning its own socket + connectivity code.
- createOffersCubit + the chat/market/profile screens use the shared
connection; dead createMessagesCubit/createTrustCubit factories removed.
- DI registers SocialConnection per identity; Bootstrap starts it (after
the inbox subscribes); switchSocialAccount disposes + recreates it.
Tests: SocialConnection lifecycle (reuse, concurrent connect, offline drop +
reconnect, unreachable retry) with a fake opener + online stream; inbox test
updated. nostr added as a dev_dependency for the channel fake.
Market offers carry a small base64 data-URI thumbnail embedded in the Nostr
event (no media server); full photo stays in the encrypted inventory. Blossom
alternative parked on branch parked/offer-photos-blossom.
# Conflicts:
# apps/app_seeds/lib/i18n/strings.g.dart
Replace the Blossom media-server approach with a fully decentralized one:
generate a small (~320px) JPEG thumbnail from the lot's cover photo and
embed it in the offer event as a data: URI, so photos ride the relays with
no server and no IP leak. The full photo stays in the encrypted inventory.
- offer_thumbnail.dart: downscale-until-it-fits data-URI builder + decoder
- market_widgets: render data: URIs from memory, http(s) URLs from network
- offers_cubit: publish a thumbnail (best-effort) in place of an upload
- drop MediaTransport/Blossom from commons_core (http/crypto deps) and the
media-server setting; parked on branch parked/offer-photos-blossom
Relay event-size limits cap the image to a thumbnail; higher-res sharing
would need the parked Blossom path.
Wire the Blossom MediaTransport into publishing: shareable lots carry
their varietyId, publishLots uploads the lot's cover photo and puts the
returned URL on the offer (best-effort — a hosting failure still publishes
the offer, just without a photo). Add a configurable media server (Comunes
default, empty to opt out) to settings and the market advanced config.
Private messages (NIP-17) arrived in the foreground with no signal: no
unread count, no badge, no OS notification. Hook both into the single
InboxService.ingest choke point.
- UnreadService: per-peer "last read" in the keystore (timestamps+pubkey
only, no message text), live count via a changes stream, active-peer
suppression so the open chat never badges or notifies.
- UnreadBadge: reusable, RTL-aware (Flutter Badge) — on the home hamburger,
the drawer "Chat" item, and per-conversation in the messages list.
- Mark-read on chat open (ChatScreen).
- NotificationService over flutter_local_notifications: generic
"New message from <name>" (no message text, for privacy), payload = pubkey,
tap opens /chat/:pubkey. No-op on web/Windows; Android POST_NOTIFICATIONS.
- i18n notifications.newMessageFrom (en/es/pt/ast).
Background/push stays out of scope (foreground-only by design).
Tests: UnreadService, NotificationService (mock plugin), InboxService hooks
(new peer notifies/counts; duplicate, own, and open-chat do not), and a
UnreadBadge widget test. dart analyze clean; commons_core green.
Slice 4 of Block 2. The pure rule was already parameterised; this adds the
policy, cold-start and UI around it.
- commons_core: WotParams (sigQty/stepMax/sigValidity, Duniter defaults) +
WebOfTrust.membersWith; npubToHex helper (NIP-19 decode) for adding roots.
- WotSettings (keystore): the active parameters, configurable — a young
network loosens them and tightens as it grows, as Ğ1 did. Defaults Duniter.
- TrustReferents: the bootstrap 'seeds' membership is measured from — a
bundled asset (empty until real founders are curated, no invented keys)
unioned with referents the user adds by npub/QR. Honest cold-start.
- TrustCubit: computes the full membership verdict against referents+params
alongside the personal circle, and exposes a TrustTier (networkMember >
inYourCircle > vouched > unknown). Certifications issued with the active
validity (they expire and renew, Duniter rule).
- UI: chat trust badge by tier; a 'Network of trust' screen (manage roots +
advanced params) reached from the profile. i18n en/es/pt/ast.
Tests: WotParams/membersWith, npubToHex, TrustReferents, WotSettings, and
TrustCubit tiers/membership. Resolves the WoT-parameters decision
(open-decisions §B). Trust net stays empty/undetermined until seeded — by
design; users bootstrap their own roots.
Adds pseudonymous, switchable social identities derived from the SAME root
seed via an account index (NostrKeyDerivation.deriveFromSeed(seed, account)).
HKDF is one-way so accounts are unlinkable to the Ğ1 key; account 0 is the
original identity, byte-for-byte unchanged (no rotation for current users),
and every account regenerates from the single seed — so switching adds
nothing to back up.
- SocialAccountStore: keystore-backed active account + max created.
- Per-identity stores (chats, profile, name cache) namespaced by account
scope (account 0 = legacy keys, no migration) so identities never mix.
- switchSocialAccount() re-derives the identity, re-scopes the stores and
restarts the inbox listener; RestartWidget rebuilds the tree to pick up
the new social singletons. DB/inventory untouched.
- Profile 'Your identities' switcher: list, create, switch (with a note
that messages/contacts are kept separate per identity). i18n en/es/pt/ast.
Tests: account-indexed derivation (legacy 0 unchanged, accounts distinct
yet deterministic, negatives rejected); SocialAccountStore; per-identity
store scope isolation. Resolves the flagged 'change identity' decision
(open-decisions §B).
Known: switching resets navigation to home (full tree rebuild).
Add multi-select to the inventory and a "Print labels" flow that renders a
PDF sheet of labels (small stickers or large cards), each carrying the seed's
common name, variety, scientific name, year/origin and a tanemaki://seed QR
that holds the seed's data offline (future scan-to-import).
- SeedLabelCodec: compact, versioned tanemaki://seed URI (encode/decode)
- LabelSheetService: pure-Dart PDF grid (pdf + barcode + DejaVu), RTL-aware
- VarietyRepository.labelRows: one row per lot, locale-picked common name
- InventoryCubit selection mode; contextual app bar + label print sheet
- i18n en/es/pt (printLabels.*)
Tests: codec, PDF service (both formats + RTL), labelRows, selection cubit,
inventory widget selection.
The vecino/market view had three gaps:
- Publishing inventory duplicated the listing. discover() appended every
offer the relay streamed, but relays legitimately resend an addressable
NIP-99 event (stored copy + live echo on publish). Merge by
(authorPubkeyHex, id) so each offer appears once; two authors reusing a
lot id stay distinct.
- No product detail. Tapping a card jumped straight to chat. Add a
read-only "product page" (MarketOfferDetailScreen) with title, mode,
category, eco badge, coarse location, price, a "Shared by" seller
section (profile fetched by pubkey) and the message button. Reached via
a new /market/offer route; cards are now fully tappable. Shows only what
the network already carries — no photos/description added to the wire.
- No filters. Add a filter bar (type, category, eco) mirroring inventory,
each chip group shown only when a discovered offer can match it. To make
the eco filter real, publish the organic flag on the wire: Offer.isOrganic
-> NIP-99 'organic' tag -> OfferMapper -> ShareableLot.
Tests: commons_core organic round-trip; app-side dedup, two-author
separation, filter logic, mapper passthrough; detail-screen widget tests.
i18n keys added to en/es/pt/ast and slang regenerated.
Reception only ran inside an open ChatScreen for a known peer, so a first
message from a new peer was invisible: nothing in local storage -> nothing
in the inbox list -> you never opened the chat -> you never subscribed.
Add InboxService: one long-lived NIP-17 inbox subscription for the whole
app (foreground), persisting every incoming message to MessageStore and
firing a 'changes' signal the inbox list live-reloads on. Reconnects when
the network returns; degrades to nothing offline. Started from main when a
social identity exists.
Make MessageStore.append idempotent (dedup by sender+timestamp+text) and
serialized behind a write lock — the global listener and an open chat's own
subscription now write the same conversation concurrently and relays
re-deliver stored gift wraps on every resubscribe. Tests for both.
Known trade-offs (follow-ups): foreground-only (no push yet); each of
InboxService/ChatScreen/MarketScreen opens its own RelayPool (a shared
connection is a later optimization).
Discovery searched the full 5-char geohash (~2.4 km) with an exact Nostr tag
match, so two devices in adjacent cells never found each other even though
publish emits the full NIP-52 prefix ladder. Search now coarsens the area to a
configurable precision (SocialSettings.searchPrecision, default 4 ~20 km) via
searchPrefix(), with a human-worded 'how far' selector (Very close / Around
here / My region -> 5/4/3) in the market setup sheet.
Also: surface a clear 'couldn't reach the servers' message when no relay
accepts a share (instead of 'shared 0'), and add wss://relay.comunes.org as the
first default relay (reliable community home; public relays are backup).
Tests: settings precision (default/clamp/roundtrip), searchPrefix helper,
neighbour-cell discovery regression (offers_cubit + commons_core nostr
transports), and the range-selector widget test.
Adds Asturianu, translated in full (345 strings), plus the wiring to
make a minority language work end to end — the OS language picker is an
unreliable way to reach it, so the in-app choice must be explicit and
remembered.
- Model Asturian as the real `ast` locale (honest, international-by-design),
not a fake `es-AST` region — slang rejects a 3-letter region anyway.
- Flutter ships no Material/Cupertino/intl localizations for `ast`, so map
the framework chrome to Spanish (`materialLocaleFor`); the app's own text
stays Asturian via slang. Fixes an "Invalid locale ast" crash when the
auto-backup date was formatted with intl.
- Persist the picked language in the keystore (LocaleStore) and restore it
at startup so it survives restarts and wins over the device locale.
- Settings: add the Asturianu tile; compare the full AppLocale so `es` and
`ast` aren't both marked selected.
Tests: LocaleStore round-trip, locale switch + Spanish-chrome fallback,
and a regression for the intl date crash under Asturian.
From on-device feedback:
- Area is no longer shown as a raw geohash 'name'. 'Use my location' is the
primary action; a human status line says whether your area is set (coarse,
never exact). The geohash code + the relay servers moved under 'Advanced'
(code field labelled 'a code like sp3e9 — not a place name'), which also
brings back node/relay selection that had been fully hidden.
- Location denial no longer yanks you into system settings — returns quietly
with an actionable inline message.
- Discovery no longer spins forever when nobody's sharing nearby: a timeout
resolves 'searching' to the empty state.
- Home card 'Open market' -> 'Market' + 'Discover and share seeds nearby'
(the word 'open' confused).
i18n en/es/pt; analyzer clean; the use-my-location test asserts the status flip.
The optional Ğ1 (free currency) integration, per g1-integration.md.
- Profile: an optional 'Ğ1 address' field, persisted locally and published in
your NIP-01 kind:0 metadata (separate from the Nostr key).
- commons_core: UserProfile/ProfileTransport carry a 'g1' field (round-trip
tested).
- Chat: when the peer published a Ğ1 address, a 'Pay in Ğ1' app-bar action opens
their wallet (url_launcher) so value moves in the wallet, not the app — copies
the address as a fallback. No payment rails in-app (sharing-model §4.3).
NOTE (vjrj): the wallet deep-link uses the Cesium web wallet as a universal
fallback; swap the URI in chat_screen._payG1 for the Ğ1nkgo/Ğecko scheme you
prefer. Analyzer clean (both packages); profile transport test covers g1.
Closes the profile loop — peers now appear by name, not a raw key.
- ProfileCache: keystore-backed cache of peers' published display names (works
offline) + shortPubkey() fallback.
- Chat: the app bar shows the peer's name (cached first, then freshened from
their kind:0 over the session); falls back to a short key.
- Inbox: each conversation shows the cached name, and missing names are resolved
over one session and cached.
- Wired via DI + TaneApp(profileCache).
Analyzer clean; ProfileCache covered by a plain test.
Drawer 'Profile' is now live.
- commons_core: ProfileTransport + UserProfile + NostrProfileTransport (kind:0
publish/fetch), exposed as SocialSession.profile. Round-trip tested against the
in-process relay (fast dart test).
- app: ProfileStore (local name/about, keystore) + ProfileScreen — shows your
shareable npub with copy, edits display name + 'about', saves locally and (when
online) publishes kind:0 so peers can recognise you instead of a raw key.
- Drawer 'Profile' -> /profile (gated like Market/Chat).
- i18n en/es/pt. ProfileStore + profile transport covered by plain/dart tests.
Analyzer clean (both packages).
Chat was only reachable via an offer's 'Message' button, and the drawer 'Chat'
sat on 'coming soon' — so messaging/trust were effectively hidden.
- MessageStore keeps a conversation index (the keystore has no key enumeration)
and exposes conversations() — peers newest-active-first with their last line.
- ChatListScreen: the messages inbox (tap a conversation → /chat/:pubkey).
- Drawer 'Chat' is now a live destination -> /messages (gated like Market).
- i18n en/es/pt. conversations() covered by a plain test (no widget hang).
Analyzer clean.
Messages were in-memory only — gone on leaving the conversation.
- MessageStore: keystore-backed (no plaintext), a capped per-peer JSON list
(last 200). Simple; the encrypted Drift DB is the eventual home at scale.
- MessagesCubit: loads saved history on start (subscribes FIRST, then loads, so
a message arriving during the load isn't dropped) and persists every sent and
received message. Wired via DI + TaneApp(messageStore).
Tests (plain 'test', no hang risk): MessageStore round-trip/per-peer/cap, and a
cubit test that reopens a fresh cubit and sees the saved conversation. Analyzer
clean; run 'flutter test' locally to confirm.
Three feedback fixes:
- Servers are fully hidden now — relays are managed automatically (default
community servers; the pool skips dead ones). Sharing setup shows only 'your
area'; no jargon-y URL field. (3 default relays for redundancy.)
- Drawer 'Market' is a live destination (was stuck on 'coming soon'), gated on
the social layer being wired like the home card.
- My own listings in the market carry a 'You' badge (and no 'message yourself'
button), so it's clear which offers are mine.
Analyzer clean. Note: could not run the flutter widget suite here (10+ min
compile after the geolocator native dep in this sandbox) — run 'flutter test'
locally to confirm; the You-badge test was simplified to be robust.
Feedback: the blank 'web address' field was unusable — nobody knows what to put,
so the market never worked at first launch.
- SocialSettings ships default public relays (nos.lol, relay.damus.io), applied
automatically for new users so the market works day one. An explicitly empty
choice still turns the network off (privacy). Exposure is minimal: offers are
opt-in and carry only a coarse geohash.
- Sharing setup now shows the servers as a short PICK-LIST (checkboxes, pre-
selected) instead of a blank field; a community's own server goes under a small
'add another' escape hatch. Intro reworded — no need to know a community.
- Tests updated (defaults) and pinned offline (setRelayUrls([])) so widget tests
don't hit the network. 22 green, analyzer clean.
Reported: sheet overflowed 7.7px with the keyboard up, and 'use my location'
seemed to do nothing.
- Config sheet is now scrollable (SingleChildScrollView) — no keyboard overflow.
- 'Use my location' shows an inline spinner + inline error (the old snackbar was
hidden BEHIND the bottom sheet, so failures were invisible). Message is now
actionable ('check location is on and the permission is granted').
- Provider hardening: request permission first; on permanent denial open app
settings; if location services are off open location settings; time-limit the
fix and fall back to last-known position so it doesn't hang indoors.
Analyzer clean; market tests green.
Sender-side offline delivery hardening.
- OfferOutbox: a keystore-backed (no plaintext) queue of lot ids to publish
later. Stores ids, not offers, so on flush each offer is rebuilt from the
lot's CURRENT state — an offline edit is respected, a deleted lot drops out.
- flushOutbox(): on reconnect, republishes queued lots and clears them (no-op
offline; drops ids whose lot is gone).
- Market screen: sharing offline parks the lots ('we'll share these when you're
connected'); opening the market online auto-flushes the queue first.
- Wired via DI + TaneApp(outbox); i18n en/es/pt.
Tests: 4 outbox + 3 flush + market UI, 20 green. Analyzer clean for new code.
Relay-strategy hardening (network-trust §3): don't hang on one relay.
- NostrChannel interface: what the transports need (sign, publish, subscribe,
reqOnce). Implemented by NostrConnection (single relay) and the new RelayPool.
- RelayPool: connects to all configured relays (skips unreachable ones, throws
only when none are reachable), publishes to every live relay (accepted if any
accepts), merges discovery deduped by event id, and survives a relay dropping.
- Transports now depend on NostrChannel, not a concrete connection.
- SocialService.openSession takes ALL configured relays (was relays.first);
createOffersCubit passes the whole list.
commons_core 63 tests green (3 new pool tests over two in-process relays);
app_seeds social/market 18 green.
Makes the coarse area human, per feedback that a typed code is jargon.
- CoarseLocationProvider interface + geolocator-backed impl (BSD-3): low
accuracy only, returns null on any denial/error (degrades quietly). Behind an
interface so it's fakeable and the plugin stays at the composition root.
- Config sheet: a 'Use my approximate location' button (shown only when a
provider is wired) fills the area from the device position, reduced to a
5-char geohash via commons_core's Geohash — a precise fix never leaves the
device. 'Couldn't get your location' on failure.
- Threaded via TaneApp(location); main wires GeolocatorCoarseLocation.
- Platform: ACCESS_COARSE_LOCATION (Android) + NSLocationWhenInUseUsageDescription
(iOS), both scoped to the coarse-area use.
- i18n en/es/pt. Widget test fills the area from a fake location. 8 tests green.
A silent safety net against in-app data loss or DB corruption, with zero
friction. Driven off the app lifecycle (startup + when hidden), it writes a
sealed .tanemaki copy into the app's private storage once a week, keeping the
newest 3 (rotating). Reuses the manual backup's encryption via the extracted
ExportImportService.buildSealedBackup(); never throws, so a failed copy can't
crash startup or backgrounding. Not registered on web (no file storage).
Settings shows a quiet reassurance line with the date of the last automatic
copy (localised via intl), hidden where no automatic backup exists.
Persistence + wiring the offers screen needs, per the product decisions:
- SocialSettings (keystore-backed, no plaintext): coarse area geohash +
configurable relay URLs, both empty by default (no bundled public relays —
don't leak metadata to third parties). Registered in DI.
- createOffersCubit(): opens a SocialSession on the first configured relay when
online, else a null-transport cubit that degrades gracefully. OffersCubit now
closes the owning session on dispose.
4 settings tests green; offers/social suites still green.
The testable core of the offers UI slice, transport-agnostic:
- OfferMapper: pure app-sharing-intent (OfferStatus) -> network Offer/OfferType
mapping; keeps price only for sales, refuses to publish private lots.
- OffersCubit: discover(geohash) streams results; publish() reports the verdict;
depends on the OfferTransport interface (fake in tests) and degrades
gracefully offline (null transport = social layer unavailable, never throws).
8 tests green (fake in-memory transport, no relay). Screen/routing/i18n come
next — they need two product decisions (coarse-area capture, relay list).
Third slice: bridge Block 1's root seed to the Block 2 transport foundation.
- SocialService: derives the secp256k1 Nostr identity from the SAME root seed
the recovery QR backs up (no extra backup), exposes npub/pubkey, and opens a
SocialSession = one shared connection carrying all three transports.
- injector.dart: registers SocialService in get_it. Local-first — derivation is
cheap + offline; no relay is contacted at startup. Replaces the old
"nodeId slice of the seed is the social pubkey" placeholder; keeps the CRDT
author id distinct (unifying it would rewrite authorship — a later decision).
- Test: deterministic identity from the seed hex, matches commons_core, rejects
malformed hex. 5 tests green; app_seeds analyzes clean (0 errors).
'Save a backup' now writes a sealed .tanemaki file (AES-256-GCM under a
key HKDF-derived from the root seed; format TANEBK v1, open and stable).
Restoring on the same identity is silent; a copy sealed by another
identity asks for the printed recovery code (TANE1 base32, typo-tolerant)
and adopts that seed — recovering your bank recovers you. Legacy plain
exports still restore. Settings gains a recovery sheet (QR + code PDF).
BackupBox/RecoveryCode live in commons_core, pure Dart, TDD.
The local half of the original Fase 2 (no network, no Offer entity yet):
- Lot sheet gains a 'do you share it?' choice (gift/swap first, sale last,
never the default); declaring plenty of abundance reveals it with a nudge.
- Lot lines and list tiles badge shared batches; an 'I share' filter and
a printable PDF catalog (paper bridge for fairs) round out the view.
- Catalog PDF embeds DejaVu (Latin-ext/Cyrillic/Greek); fonts are a
per-locale resource like the OCR packs.
Lower the bulk-digitization cliff with two more routes on top of the
already-landed CSV import and "save and add another":
- Photo-first drafts (capture now, catalogue later): burst-capture
photos (camera or multi-gallery) into unnamed draft varieties, shown
in a "to catalogue" tray, hidden from the main list until named.
Adds Variety.isDraft (schema), addDraftVariety/watchDrafts/nameDraft,
the triage sheet and the inventory banner.
- On-device OCR label suggestion (Tesseract, offline, no Google): a
"Suggest name from photo" button in the naming dialog behind a
LabelTextExtractor interface (Tesseract on Android/iOS, no-op
elsewhere). Reads the largest print via hOCR bounding boxes, drops
boilerplate/low-confidence noise, preprocesses (grayscale, contrast,
upscale) and sweeps rotations (0-315 deg) so tilted packets still
read. Bundles tessdata_fast eng+spa; validated on-device against real
packets. The photo is written to a temp file deleted immediately in a
finally block (the plugin needs a path) - a bounded, documented
exception to no-plaintext-at-rest.
This commit also carries the co-developed schema evolution v5 to v8 that
shares these files (organic flag, species viability years, crop
calendar, lot provenance/abundance/preservation format, condition
checks) plus their exports/migrations and i18n.
Tests: CSV/draft/OCR unit + widget + migration green in isolation.
Note: the full widget suite currently hangs (>10 min) - under investigation.
Import a spreadsheet list (the same 21-column schema the CSV export
already produces) as new varieties/lots. Tolerant reader: columns
matched by header name in any order, only variety_label required,
unknown enums fall back to a safe default, rows sharing variety_id
collapse into one variety with several lots. Species re-linked by
scientific name. Additive by design (fresh ids + HLC), so it never
overwrites existing rows; JSON stays the canonical id-reconciling import.
Adds a hand-rolled RFC 4180 parser (no new dependency), an importCsv
path in VarietyRepository/ExportImportService, an 'Import from CSV'
tile in the backup section, and en/es strings.
Note: i18n .g.dart also carries pre-existing About/intro strings from
the working tree (regenerated by slang).
Interchange export/import for Phase 1 (data-model §7):
- JSON: canonical, versioned envelope (formatVersion 1) with all sync
metadata verbatim, photos embedded as base64, tombstones excluded.
Species are re-resolved on import by scientific name (catalog ids are
per-install). Reader tolerates unknown fields/enum values (§5.2) and
rejects newer format versions with a clear error.
- CSV: export-only spreadsheet flatten, one row per lot, RFC 4180
escaping, never any photo bytes.
- Import merges by UUIDv7 id in one transaction: insert-if-unknown
preserving original stamps, last-writer-wins by packed HLC for known
mutable rows, append-only movements; afterwards the local clock
receiveEvent()s the newest imported stamp so it never runs behind.
- Settings gains a Backup section (export CSV/JSON, import JSON with
confirmation); file dialogs behind a FileService interface backed by
file_picker (MIT).
- Tests: codec round-trip and tolerance, reconciler LWW, repository
export→import round-trip (fresh DB, idempotent re-import, newer-local
wins, clock monotonicity, species re-resolution), backup widget flows.
