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.
