A bundled, curated knowledge layer — the differentiator of a serious
seed app. For a variety's crop it shows how the plant reproduces and what
it takes to keep the variety true: life cycle, pollination (self/cross +
insect/wind), isolation distance, how many plants to save from, dry/wet
processing, a difficulty pill, and a short tip — all in human words.
- assets/catalog/seed_saving.json: curated public-domain data (Seed to
Seed / Seed Savers), keyed by botanical FAMILY (defaults) with
per-species/genus OVERRIDES that win — so e.g. Vicia faba is correctly
insect-cross-pollinated despite the selfing Fabaceae default, and maize
is wind-pollinated with a large population. Notes are locale-keyed
(es/en), extensible to any language — a starter set, not a ceiling.
- domain/seed_saving.dart (pure): enums + SeedSavingGuide (merge, note
fallback) + SeedSavingData.guideFor (species → genus → family).
- data/seed_saving_catalog.dart: loads the asset once into an in-memory
singleton (no DB table, no migration); injector loads it at startup.
- VarietyDetail gains (from the linked species — the reliable
key, vs the editable category); detail screen shows a _SeedSavingView
when a guide resolves.
- i18n seedSaving block (labels + enum values + params) in en/es/pt/ast.
- Tests: domain lookup/merge, the real asset's key corrections, and the
detail section shows/hides. 314 suite tests green; analyze clean.
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.
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.
Add a small curated catalog of Iberian horticultural species and let a variety
be linked to it from the edit sheet.
- assets/catalog/species.json: 14 species with botanical family and ES/EN
common names (wikidata_qid/gbif_key deferred to the varilla enrichment).
- SpeciesRepository: idempotent seedBundled (is_bundled rows, keyed by
scientific name) + search by scientific/common name with a locale-best label.
Seeded on startup from DI.
- VarietyRepository.linkSpecies: sets species_id and prefills category from the
species' family when empty (never overwrites an existing category).
VarietyDetail now carries the scientific name.
- Edit sheet gains a live species-search field; the detail view shows the
scientific name (italic). i18n strings added (ES/EN).
Tests: catalog parse, idempotent seeding, search by scientific/common name,
linkSpecies prefill semantics, and a widget test for the autocomplete → link →
scientific-name-shown flow. Full suite: 32 passing, 0 skipped.
