| 1 | """Meta-test: every documented spec/CLI option must have a real consumer. |
| 2 | |
| 3 | Audit 01 caught two dead options (P14 ``defaults.differential`` and |
| 4 | P15 ``compute(weights=...)``) that were defined, documented, and never |
| 5 | read by any code path. Sprint 03 wired both of them. This test pins |
| 6 | that wiring so a future refactor that drops the consumer surfaces here |
| 7 | rather than in a user's report. |
| 8 | |
| 9 | The check is a literal substring grep: each documented option name |
| 10 | must appear in *consumer* code outside the spec / scoring module that |
| 11 | declares it. We walk ``src/dlm_sway`` for the substring and compare to |
| 12 | a known set of declaration sites; anything else counts as a consumer. |
