kebab/crates/kebab-cli/tests/cli_schema.rs

//! Integration: spawn the kebab binary and parse `kebab schema [--json]`.
//!
//! Each test builds an isolated TempDir-rooted XDG layout, runs
//! `kebab ingest` over an empty workspace (which creates and migrates
//! kebab.sqlite), then exercises `kebab schema` in JSON and text modes.
//! Using an empty workspace avoids the embedding model dependency while
//! still seeding the DB so `open_existing` inside schema_with_config
//! succeeds (a NotIndexed error fires when the DB file is absent).
