Stand up the Tanemaki monorepo and the first end-to-end vertical slice of Block 1 (offline, encrypted inventory): add a seed → see it in a categorized, searchable list → it persists → reopen and it's still there. Architecture (state management like G1nkgo, adapted to Tane's reality): - flutter_bloc (Cubit-first), but the encrypted Drift DB is the single source of truth; cubits stream from repositories (no hydrated_bloc/Hive, which would write plaintext at rest). - get_it composition root; go_router; slang i18n (ES/EN, Weblate-friendly JSON). Workspace & core: - pub workspace: packages/commons_core (pure Dart) + apps/app_seeds (Flutter). - commons_core primitives: UUIDv7 IdGen, Hybrid Logical Clock, Quantity value type (+ plant-aware QuantityKind), IdentityService root-seed stub. Data & security: - Drift schemaVersion=1 with all 10 Block-1 tables + common CRDT columns (HLC updated_at, last_author, tombstones); Movement append-only. - SQLCipher via an injectable executor that refuses to open a plaintext DB; DB key + root seed in the OS keystore (separate secrets). - Exported drift_schema_v1.json + migration scaffold. Tests (near-TDD; nothing merges without tests): - commons_core units (24), Drift migration test, "no plaintext at rest" security guard (runs where SQLCipher is present, skips otherwise), repository, widget, full quick-add flow, file-reopen persistence, and a no-hardcoded-strings i18n guard. GitLab CI: format + analyze + test + coverage. Follow-on Block-1 stories (item detail/edit, species catalog, germination UI) and all of Block 2 remain out of scope.
