 **Flow** is the authoring layer for combined schedules and automations. The full-screen editor stores a block graph as the source of truth and compiles it automatically: a pure weekday + time-range + thermostat path becomes a native schedule, while richer logic becomes a generated automation. Generated schedule/automation rows carry their Flow provenance and are read-only in the legacy editors.
 
+The reusable Flow preset library is stored as standalone JSON files in `presets/`. Each file contains its name, description and complete Flow graph, while the UI loads the embedded preset catalog dynamically instead of hard-coding graphs in JavaScript.
+
 Available blocks include weekday/time/date ranges, the application Night mode, outdoor/device/zone temperature, house/device/zone/group state, arbitrary Home Assistant state/numeric/attribute/availability checks, a constant diagnostic source, AND/OR/NOT, thermostat actions, direct GREE actions and group actions. The GREE action uses the existing `DeviceCommand` fields (power, mode, target, fan, swing, quiet, turbo, light, air, xfan, health and sleep). Multiple branches can feed an action; the compiled runtime preserves the graph logic.
 
 Quick preset/setpoint overrides normally hand control back at the next schedule boundary. Temporary Quick Thermostat adds explicit start/finish rules such as duration, exact time, temperature reached/stable or next schedule boundary.

+
+Presets are data files, not JavaScript definitions. Every preset lives in `presets/<id>.json` and contains `id`, `category`, localized `name`, localized `description`, and the complete `flow` graph (`nodes` + `edges`). `build.rs` validates and embeds the directory, exposes `/presets/index.json` plus `/presets/<file>.json`, and the Flow editor loads that library dynamically. Device/zone/group placeholders such as `$zone1`, `$zone2`, `$device1` and `$group1` are resolved when a preset is applied. Adding a preset therefore does not require adding graph-building code to `web/js/flows.js`.
 
 The canvas supports multi-selection (Shift/Ctrl/Cmd), `Ctrl/Cmd+A`, Select all / Clear selection toolbar actions, and dragging the whole selected group while preserving relative positions.
