+> DISCOVER: G09 WARN -- MTI=86 (below 95 target). Root cause: evidence=0.28 (only 17/61 stories
+>   had evidence). 44 API feature stories (F37-API, F37-HEALTH, F37-OBJ_IDPATH, etc.) had
+>   artifacts (implemented endpoints) but zero linked evidence -- no commit tags, no receipt files.
+>   Formula: coverage*0.5 + evidence*0.2 + consistency*0.3 = 0.5 + 0.056 + 0.3 = 0.856 -> 86.
