1//! Single source of truth for the `~/.innate` directory layout.
2//!
3//! ```text
4//! ~/.innate/
5//!   settings.json            ← user config (root)
6//!   settings.schema.jsonc    ← schema for settings.json (root)
7//!   data/                    ← databases + runtime state
8//!     personal.db (+ -shm, -wal)
9//!     daemon_state.sqlite
10//!     daemon.pid
11//!   logs/                    ← operational logs
12//!     daemon.log
13//!     mcp.log
14//!   sessions/                ← agent session traces (watched by the daemon)
15//!     session.log
16//! ```
17//!
18//! All callers must go through these helpers rather than re-deriving paths, so
19//! the layout stays consistent. `ensure_layout()` creates the subdirectories and
20//! relocates files from the older flat layout on first run.
