//! Documented exit-code coverage.
//!
//! `NET_CLI_PLAN.md:§"Exit codes (locked)"` defines the
//! discriminator → code table. This test pins each documented
//! code by invoking a fixture that produces it.
//!
//! Codes covered today (Phase 1 + Phase 3 ICE):
//! - 0 Success — `net version`.
//! - 1 Generic — `net identity show /nonexistent`.
//! - 2 InvalidArgs — `net snapshot get --bogus`.
//! - 3 SDK error — covered by other commands (no fixture pinned
//!   today because triggering a substrate error deterministically
//!   requires a larger harness).
//! - 8 ConfirmationRefused — `net ice freeze-cluster` with non-TTY
//!   stdin and no `--yes`.
//!
//! Codes 4–7 + 10–12 will be pinned as the matching command
//! surfaces ship (ICE simulation guard / signature verification /
//! connection failure / timeout / daemon factory / db query
//! parse). The simulation-blocked path (code 4) is reachable only
//! when the SDK returns `SimulationRequired` from `commit`, and
//! the CLI always simulates before committing, so triggering it
//! needs a deliberately crafted runtime fixture.
