//! Regression guard for #5987: `zeph_commands::COMMANDS` (the static list `/help` renders
//! from) has drifted from the real `CommandRegistry` registrations in `Agent::run` at
//! least 4 times. This asserts every handler registered in either of the two production
//! registries (`build_session_debug_registry`, `build_agent_command_registry`) has a
//! matching name in `zeph_commands::COMMANDS`, so a future handler addition without a
//! matching `COMMANDS` entry fails CI instead of silently hiding the command from `/help`.

use crate::agent::slash_commands::{build_agent_command_registry, build_session_debug_registry};

/// Registered in `#[cfg(test)]` builds only (`build_session_debug_registry`) to exercise
/// the non-fatal `CommandError` dispatch path — not a real user-facing command, so it is
/// intentionally excluded from the drift check below.
