homeassistant_cli/commands/
registry.rs

1//! `ha registry entity` commands.
2//!
3//! Registry operations are config mutations that reshape the Home Assistant
4//! database (distinct from the read-only state commands in `ha entity`).
5//! Safety defaults:
6//! - `--dry-run` short-circuits before opening a WebSocket connection.
7//! - Interactive confirmation is required when stdout is a TTY and `--output`
8//!   is not `json`. JSON mode and non-TTY stdout both auto-confirm.
9//! - Partial failures (some removals succeeded, some failed) exit with
10//!   [`exit_codes::PARTIAL_FAILURE`] so agents can detect mixed outcomes.
