"""Executable spec for postmortem.subagent_terminal_status.

Run directly: `python3 postmortem/tests/test_terminal_status.py`.
Exits 0 on pass, 1 on failure. No pytest dependency — the plugin has
no test harness, and a status-classifier is small enough to pin with
plain asserts.

Pins issue #3: the terminal-status text-scan over-reports BLOCKED for
shipped implement runs, because `\\bBLOCKED\\b` fires on the end-report's
own template lines (`BLOCKED file:     BLOCKED.md`, `Blocked detail:`)
and on prose narrating a surmounted blocker. The authoritative signal is
the structured `Status:` line of the end-report, not any keyword
occurrence in the body.
