Round 10 review, finding 6. The cross-repo contract still documented carrier 1 as "any value other than false/0 is truthy" after R10-4 made pixelpass match it exactly. A future producer following the fixture could emit "true" and silently lose the carrier. Committed byte-identical with pixelpass's copy in the same session, as the file's own rules require.
