Use the same rules as kimi-code. One valid turn {200,60,800,10} imports with input_total=1010 and total=1070. Negative usage produces usage_shape_deviation; usageScope=“lifetime” produces usage_scope_unknown; seconds-like time=1767225600 is skipped with timestamp_unparseable, without guessing by multiplying by 1000. Expected: one event, three diagnostics, degraded.
