Plan steps · 4 ops

Navigate to /api/matches and read the first match id from the response

Navigate to /match-odds/<first-id>.json using the captured id (the per-match odds artifact)

Inspect the books array and read each book's devigged.home, devigged.draw and devigged.away values

Verify that for every book in the artifact the three de-vigged probabilities (home + draw + away) sum to 1.0 within a tolerance of plus or minus 0.001. Any book whose de-vigged probabilities sum to more than 1.001 (the bookmaker margin was not removed) fails this test.
