NestQuest helps households coordinate daily life, chore tracking, custody schedules, and shared tasks directly within Home Assistant. Version 0.2.0 ships the integration foundation (a configuration scaffold providing the package and manifest, shared constants, a single-instance config flow, setup/unload lifecycle handling with an options-reload listener, an options flow for horizon days / day rollover time / panel idle timeout, and HACS metadata) plus its persistence layer: an integration-owned SQLite database (`nestquest.db`) with WAL mode and foreign keys, a versioned migration runner stamping schema version 1 across eight tables (children, admin_users, schedule_rules, task_definitions, presence_schedules, presence_overrides, task_instances, completion_events), typed DAO layers so no other feature writes raw SQL, an append-only completion-event log, and startup handling that creates a missing database, opens a valid one, and refuses — without touching a single byte — to start on a corrupt one. Sensors, calendar events, and service calls are forthcoming in later releases and are not yet part of the integration.
