-//! Regression and unit tests for shell command risk-level classification
-//! (issue #172, PR #368).
-//!
-//! These tests live here (instead of inline in `src/tools/builtin/shell.rs`)
-//! because the project's no-panics CI check scans `src/**/*.rs` for
-//! `assert_eq!` / `assert_ne!` / `.unwrap()` in added lines.  All assertions
-//! on the public `ShellTool` API belong here.
-//!
-//! All tests access the shell tool through the public `ToolRegistry` +
-//! `Tool` trait surface (`risk_level_for`, `requires_approval`).
-//!
-//! ## What is tested
-//!
-//! 1. **Risk level tiers** (`High`, `Medium`, `Low`) for representative commands.
-//! 2. **Word-boundary matching** — commands whose names are substrings of other
-//!    words must not be misclassified.
-//! 3. **Pipeline aggregation** — the whole pipeline takes the maximum risk of
-//!    its segments.
-//! 4. **Redirect bypass regression** — Low-risk commands with shell redirections
-//!    must return `UnlessAutoApproved`, not `Never`.
-//! 5. **`git push` regression** — non-force push is explicitly `Medium`; force
-//!    variants remain `High`.
-//! 6. **`risk_level_for` trait method** — delegates to classify_command_risk.
