Second production slice: the concrete Nostr backend on the shared connection,
using the vetted nostr package's crypto (NIP-44 spec-vector tested, gift wrap).
- NostrConnection: one dart:io WebSocket + identity + EVENT/OK, REQ/EOSE via
the library's Event/Filter/Request. Pure Dart, no Flutter.
- NostrOfferTransport (NIP-99 kind 30402) + Nip99Codec: geohash coarsened to a
NIP-52 prefix ladder on the wire; Offer stays inventory/location-agnostic.
- NostrMessageTransport (NIP-17): send/inbox via the library's DirectMessage
gift-wrap onion.
- NostrTrustTransport (custom addressable kind 30777): certify/revoke/discover.
- MiniRelay test support + integration tests: offers, messaging (metadata
privacy), WoT membership + revoke, and trust-filters-offers — all over ONE
shared connection, hermetic in-process relay.
Renamed the core offer lifecycle enum OfferStatus -> OfferLifecycle to avoid
colliding with app_seeds' sharing-intent OfferStatus (no Block 1 code touched;
app_seeds analyzes clean, 0 errors). commons_core: 55 tests green.
Typing in the edit sheet ran heavy DB work on every keystroke: a SQL
LIKE search on the species field, and a full species-catalog load plus
O(n^2) label matching on the name field. That made typing laggy.
Debounce both lookups (250ms) so they only run once the grower pauses,
and drop stale results with a per-field query counter so an earlier
response can't flicker an outdated suggestion back in.
The de-risking spike validated the whole social happy path, so Block 2 moves
from "do NOT start" to STARTED. Records the build order (transport foundation in
commons_core first, on the vetted pure-Dart nostr lib) and marks open-decisions
D.3/D.7 as resolved by the spike.
Infer the catalog species a free-text variety label names ("Maiz de la
abuela" -> Zea mays) and prefill the category from the species family.
- Pure, testable matcher (domain/species_autoclassify.dart): whole-word,
accent/case-insensitive, Unicode-aware (any script), longest-name-wins,
ambiguous names left unclassified, light plural fold.
- Quick-add and draft naming auto-link the species when the field is empty
(non-destructive; an explicit category is kept).
- Edit sheet offers a one-tap suggestion from the typed name.
Tests: matcher unit, repository integration, SpeciesRepository.classifyLabel,
and an edit-sheet widget test.
The variety edit sheet grew with v8 fields (organic, needs-reproduction,
crop calendar) and its Save button, sitting at the bottom of the
SingleChildScrollView, dropped below the fold — the species-linking
widget test could not reach it (tap landed off-screen, species never
linked). Move the fields into a Flexible scroll area and pin the
Cancel/Save row as a fixed footer so Save is always visible and tappable.
Full suite green (233 tests).
Adds TrustTransport as the third interface on the shared NostrConnection,
completing the social-layer happy path in the spike:
- WebOfTrust: pure, Flutter-free Duniter membership rule (N certs from members +
within distance D of bootstrap referents), iterated to a fixpoint. The
commons_core-worthy piece; TDD'd (threshold, distance cutoff, transitive
growth, expired/revoked/self exclusion).
- NostrTrustTransport: certifications as a custom addressable kind (30777,
keyed by issuer+subject) — certify renews, revoke replaces, certs expire.
- Trust filters spam (network-trust §2): seeds certify Alice; Eve stays
uncertified; Bob discovers both offers and annotates authors — Alice known,
Eve unknown — all over ONE shared connection.
Findings updated: WoT risk High -> Medium (policy/bootstrap, not feasibility);
overall scope Medium-High -> Medium — all three transport contracts now proven.
30 tests green, analyzer clean, Block 1 untouched.
Extends the Block 2 spike to attack the highest-risk unbuilt piece (private
messaging) and to prove the Q2 architecture recommendation with running code:
- NostrConnection: one shared socket+key+sign+REQ/EOSE lifecycle. Refactored
NostrOfferTransport onto it; added NostrMessageTransport — two thin contracts
on ONE connection (the 'one connection, three interfaces' shape).
- NIP-44 v2 encryption (secp256k1 ECDH -> ChaCha20 + HMAC, length-hiding pad).
- NIP-17/NIP-59 gift-wrap: rumor(14) -> seal(13) -> wrap(1059, ephemeral key).
Alice->Bob DM round-trips through the relay: encrypted, sender authenticated,
and metadata-private (relay/eavesdropper sees only ciphertext, an ephemeral
author and the recipient p-tag — Alice stays hidden).
Findings updated: NIP-17 risk drops Medium-High -> Medium (hardening, not
feasibility); next de-risking target is the web of trust. NIP-44 not yet
vector-verified (noted). 20 tests green, analyzer clean, Block 1 untouched.
The slang aggregator fell out of tracking through merge resolutions while its
per-locale siblings (strings_en/es/pt.g.dart) and database.g.dart stayed
tracked, so it kept showing as an untracked file on main. Track it too for
consistency with the repo's commit-generated-code convention.
The repository clock started fresh at Hlc.zero on every launch and was
never re-seeded from the database. After a restart, if the device wall
clock lagged behind stamps already stored (e.g. rows imported from a
peer whose clock ran ahead), a local edit was stamped *older* than the
row it edited and silently lost last-writer-wins — so lot changes made
on one device did not update when the backup was imported on another.
Re-seed the clock lazily from the newest stored `updatedAt` before the
first local stamp of the session, mirroring what importInventory already
does with the incoming max. _stamp() is now async.
Tests: add a lot-level LWW re-import test (the variety case was covered,
the lot case was not) and a restart-regression test that reproduces the
lagging-wall-clock scenario.
Grow the bundled species catalog from 14 hand-curated entries to ~1200
edible/cultivated species, internationalized in 13 languages (es, en, fr,
de, it, pt, ca, gl, eu, ar, zh, ja, ru — Latin + Arabic RTL + CJK + Cyrillic).
- Add a reproducible generator (tool/gen_species_catalog.dart) that queries
Wikidata (CC0, no attribution burden) in two phases, filters out
non-vernacular noise (author citations, ranks, initials) and applies a
relevance floor, then merges hand-curated, authoritative core-crop data
(tool/curated_overrides.json: names, family, viability_years). GBIF is used
only as an identifier. The generated species.json (v3) is committed.
- Carry wikidata_qid and gbif_key through the parse/seed pipeline; the columns
already existed, so no DB migration.
- Rewrite seedBundled to one read + one batch (was a SELECT per species on
every startup — a real cost at ~1200 rows) and keep it idempotent with
backfill of the new reference fields.
- Move species search filtering to SQL (LIKE) so a large catalog is not pulled
into memory on every keystroke.
- Cover the generator transform, the generated asset, and the new fields with
tests.
Throwaway research spike (spike/ branch, outside pub workspace, no prod deps
touched). Validates the open Block 2 decisions before committing a funded round:
1. Deterministic one-way secp256k1 (Nostr) key derived from the Ğ1 root seed
via HKDF — user still backs up ONE thing. Reproducible + signs (BIP340).
2. OfferTransport abstraction over Nostr NIP-99 (kind 30402); Offer stays
inventory/location-agnostic, geohash coarsened on the wire (tested).
3. publish->discover-by-geohash proven end-to-end against an in-process
hermetic mini-relay (~34ms round-trip).
Findings + risks + recommendation in docs/design/spike-block2-findings.md.
Block 1 suite untouched. 14 tests green, analyzer clean.
- Android release signing reads a gitignored key.properties, falling back
to debug keys so contributors can still build --release.
- CHANGELOG.md (human, newest-first) + Fastlane/F-Droid metadata (en/es)
with descriptions derived from docs/intro.md.
- docs/release.md: the by-hand build + manual smoke checklist (no CI yet).
- inventory_scale_test guards the list query against N+1 at 3000 varieties.
- Add rtl_smoke_test covering inventory, detail (lot sheet) and settings
under Directionality.rtl, with an Arabic label and vernacular name.
- Ship pt.i18n.json (Portuguese) as proof the locale pipeline scales beyond
es/en; wire its language tile in Settings.
- docs/i18n.md documents the Weblate-ready flow for adding locales.
Add a read-only "Learn more" section on the variety detail that surfaces
verified external references for the linked species, built deterministically
from bundled identifiers — no titles bundled, no network, offline-first:
- GBIF taxon page from the backbone key
- Wikipedia via Wikidata Special:GoToLinkedPage (locale-aware, RTL-safe,
falls back to the Wikidata item when a language lacks the article)
- Wikispecies from the scientific name
Enrich the bundled catalog (species.json v3) with gbif_key + wikidata_qid for
all 14 species, cross-checked (each QID carries GBIF ID P846 = the key).
Schema already had the columns; seedBundled now persists and backfills them.
The grower's own manual links stay but are demoted (progressive disclosure):
the section only shows when links exist and "Add link" is a low-emphasis
button, since hand-adding a link is the rarer power move.
Pure-Dart link builder is unit-tested; repo persistence/backfill and the
detail-screen section are covered too.
'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.
InventoryCubit subscribed to watchInventory() and watchDrafts()
separately — two overlapping StreamGroups (both watching attachments)
re-emitted in a tight loop that starved the event loop and hung widget
tests' pumpAndSettle for 10+ minutes (home/inventory/quick-add all
timed out). Replace both with a single watchInventoryView() stream that
loads the catalogued list and the draft tray from one StreamGroup.
Full widget suite no longer hangs: 165 pass. One unrelated failure
remains in the v8 variety edit sheet (Save button pushed off-screen by
new fields).
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.
The quick-add sheet no longer closes on every save: a new 'Save & add
another' action saves the seed, clears the form (keeping the chosen lot
type), refocuses the name field and shows an 'N added' running count, so
a whole shelf can be entered without reopening the sheet each time.
Plain Save still closes it. Adds a dedicated label field with its own
controller, submitAndAddAnother() on the cubit, and cubit + widget tests.
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).
seedMuted (hints, card subtitles, search placeholder) was #8A9880 —
2.62:1 on the canvas and 3.05:1 on white, failing AA for the 13px text
it colours. Darkened to #617057: 5.30:1 on white, 4.56:1 on canvas,
4.88:1 on the field fill, same muted green-grey hue.
The new contrast test also caught the app-bar green: white titles on
#3E8C38 were 4.19:1, so it is nudged to #3A8434 (4.64:1) — a barely
visible change.
test/ui/theme_contrast_test.dart pins the WCAG relative-luminance math
and asserts every text/background pair the palette actually uses.
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.
Add an "About" entry to the navigation drawer (below Settings) so the
About screen is reachable without opening Settings first.
Recolour the launcher icon and native splash to a white sprout on brand
green (#2F7D34) — the previous dark-green-on-light-green had almost no
contrast. Regenerate Android, iOS and web icons and the light/dark splash.
Add filter chips above the inventory list, one per category in use and
one per lot form actually held; results apply search ∧ category ∧ form.
An active filter that empties the list shows a distinct 'no matches'
state and a clear-filters button. VarietyListItem now carries the set of
lot forms it holds (one aggregate query), and the stream re-emits on lot
changes.
Accessibility: category headers use the text theme so they honour the
system font scale; the list avatar is excluded from semantics (the tile
title already announces the name); the edit action uses the green action
colour (≥3:1 on the canvas, up from 2.62:1). Add category/form/clear
filter tests and a tap-target-size guideline test.
Apply a Material 3 seed-green palette and rounded components across the
home, inventory, quick-add, quantity picker and variety-detail screens.
The full-screen photo viewer can now set any photo as the cover (via
attachment sort order) and delete after confirmation. Lot forms and
packaging surface as choice chips.
Extract About out of Settings into its own screen (app version via
package_info_plus, website link). Add es/en strings for the new lot
types, presentation, home tagline and About. Update Seedees v2 mockups.
Add flutter_launcher_icons + flutter_native_splash config (green sprout
on the #E7F1E0 canvas, light & dark) and regenerate Android/iOS assets.
Enable the web platform (favicon, manifest, PWA icons). Add
package_info_plus for the version string shown on the About screen.
Expand LotType from {seed, plant} to six append-only forms (seed,
seedling, plant, tree, bulb, cutting) and add an optional Presentation
attribute (pot/tray/plug/bareRoot/rootBall) kept separate from quantity
so 'how many' and 'in what packaging' never conflate.
Add attachments.sortOrder so the cover photo is the lowest-ordered one,
enabling reordering from the full-screen viewer. Expand QuantityKind
with the new plant-aware forms.
Migrations are additive (v1→v5 all covered by migration_test); enum
values are stored by name and appended only, keeping CRDT sync safe.
Flutter disables pointer-drag on scrollables/PageViews on desktop by default,
so the small photo carousel (and lists) couldn't be swiped with a mouse. Add an
app-wide ScrollBehavior that includes mouse/trackpad/stylus drag devices.
54 tests green; Linux runs.
- Adding a photo (quick-add and detail) now offers a Camera / Gallery chooser
(shared pickPhoto helper); camera errors on desktop degrade gracefully.
- Full-screen viewer: pinch-to-zoom pans only while zoomed, so a plain
horizontal swipe pages between photos again.
54 tests green; Linux runs.
- Bundle the real sprout logo (docs/logo.png → assets/logo.png) and show it on
the home menu instead of a Material icon.
- Settings screen: switch language (Español / English / system) via slang, plus
an About tile (logo, app name, one-line description). Drawer "Settings" is now
active and routes to /settings.
Tests: drawer Settings opens the screen and shows the language options. 54 green.
- Photo carousel dots are now tappable (jump to that photo) with a larger hit
area, so you can browse all images even when swiping the small thumbnail is
awkward.
- The quantity unit scale is a Wrap instead of a horizontal scroll, so every
unit stays visible instead of being cut off.
- Each lot shows a Seeds/Plantel chip (green vs teal, with icon) so mixed
seed-and-plant varieties read clearly at a glance.
- Germination is hidden on plant lots (it only applies to seeds).
- Tapping a photo in the detail carousel opens a full-screen, swipeable,
pinch-to-zoom viewer.
Tests: plant lot shows the Plants chip and hides germination. 53 green; Linux runs.
Add Wikipedia/forum-style URLs to a variety:
- Repository: addExternalLink/removeExternalLink (soft delete); watchVariety
loads links and re-emits on external_links changes; ExternalLinkItem model
(title preferred over URL for display).
- Cubit: addExternalLink/removeExternalLink.
- Detail: a "Links" section with tappable link chips (open via url_launcher,
http(s):// prepended if missing), delete per chip, and an "Add link" dialog
(URL + optional title).
Tests: repo add/remove + widget add/remove. 52 green; Linux runs.
The app now opens on a main menu instead of straight into the list:
- HomeScreen (mockup 02): sprout logo over a faint seed-glyph watermark, with
big "Your inventory" (→ /inventory) and "Open market" (Block 2, "coming soon")
destinations.
- AppDrawer (mockup 03): Inventory is live; the social items (market, profile,
chat, wishlist, following, settings) are shown disabled with a "coming soon"
tag so the roadmap is visible. Drawer is available on home and inventory.
- Routing: / → home, /inventory → list, /variety/:id → detail.
Tests: home shows the menu + navigates; drawer opens + navigates. quick-add flow
updated to go home → inventory. 50 green; Linux runs.
Photos:
- Repository addPhoto/removePhoto; VarietyDetail.photos (list); loads all photos.
- Detail: a 140×140 photo carousel with page dots, delete-current, and add-photo
(gallery); empty state shows an add-photo button.
- watchInventory now re-emits on attachment + species changes (StreamGroup), so
a photo added on the detail screen refreshes the inventory avatar immediately
(fixes avatars not updating).
Also carries the concurrent harvest-date work: lots gain an optional harvest
month (schemaVersion 3 + from2To3 migration, drift_schema_v3 exported), a
month/year harvest picker, and localized month names.
48 tests green (add/remove photos, avatar reactivity, v1→v3 migration); Linux runs.
Replace the free-text harvest year with a themed month/year picker:
a tappable field opens a green-styled dialog with month and year grids
(navigable, paginated years), month optional. Lots now read e.g.
"September 2021" or just "Year 2021".
- schema v3: add nullable Lot.harvest_month (1..12) + migration + tests
- repo/cubit propagate harvestMonth; localized month names (en/es) via slang
The "also known as" names were read-only; now they can be added and removed:
- Repository: addVernacularName + removeVernacularName (soft delete);
VarietyDetail.vernacularNames carries ids (new VernacularName model).
- Cubit: addVernacularName / removeVernacularName.
- Detail: deletable name chips + an "Add name" chip opening a small dialog;
the section is always visible so names can be added when empty.
Tests: repo add/remove + widget add/remove. 44 green.
Lots could only be created; now they can be edited and removed:
- Repository: updateLot (LWW) + softDeleteLot (tombstone).
- Cubit: updateLot / deleteLot.
- The add-lot sheet is now a shared add/edit sheet — tapping a lot opens it
prefilled (type, year, quantity), with a trash action to delete. The reactive
detail view refreshes on save/delete.
Tests: repo updateLot/softDeleteLot + widget edit-lot and delete-lot. 42 green.
