"""Seam test for scripts/repo_gates.py.

Run:  python3 scripts/test_repo_gates.py

WHY THIS EXISTS. An entry point is a seam by definition: a runner that LISTS a gate but never
executes it is inert and fully green, and this project has shipped an inert seam four times. So
the assertion is on each member gate's OWN distinctive stdout — never on the runner's summary
line, which the runner can print without ever calling anything — plus the exit code, which is a
runner's actual effect.

Red-proofed 2026-08-02: replacing run_gate's body with `return 0` (the inert runner) turns
test_every_member_gate_actually_ran red while the summary still prints "all felhom.eu gates OK".
