 ## Project Structure & Module Organization
 Zeph is a Rust workspace (`Cargo.toml`) with the CLI entrypoint in `src/` and domain crates in `crates/` (for example: `zeph-core`, `zeph-llm`, `zeph-memory`, `zeph-tools`, `zeph-tui`).
-Top-level integration tests live in `tests/`, while crate-specific tests and benches live under each crate’s `tests/` and `benches/` directories. Documentation sources are in `docs/src/` (mdBook), runtime defaults are in `config/default.toml`, and container assets are in `docker/`.

 - Prefer zero-warning `clippy`; avoid `unwrap`/`expect` in production code when proper error propagation is possible.
 - Any user-facing change must update relevant docs, config defaults, and `CHANGELOG.md` (`[Unreleased]` section).
 - For new functionality, provide all integration points: config section, CLI subcommand/argument, TUI command palette entry, `--init` wizard, `--migrate-config` migration step, live testing playbook in `.local/testing/playbooks/`, and coverage row in `.local/testing/coverage-status.md`.

 ## Coding Style & Naming Conventions
-Use Rust 2024 edition and MSRV `1.88`. Follow `rustfmt` defaults (4-space indentation) and keep Clippy warnings at zero where practical.

 Use `snake_case` for functions/modules/files, `PascalCase` for types/traits, and `SCREAMING_SNAKE_CASE` for constants. Prefer small modules with explicit responsibilities; keep public APIs in `lib.rs` minimal and re-export intentionally.
