Principaux constats
L'information utile ne se resume pas toujours au premier rang global.
Support tasks exposed unsafe promises.
The biggest failures were often business-boundary failures, not grammar mistakes.
Japanese writing separated grammar from natural tone.
Correct Japanese was not enough. Natural, concise business phrasing mattered.
Extraction revealed the widest reliability gap.
Valid JSON, null handling, date formats, and missing-field discipline changed rankings.
