synthetic-cross-day expectations (synthetic)

A cumulative row spans 2026-09-23T10:00:00Z–2026-09-25T18:30:00Z, with token=1000, api_call_count=3 and only first_seen/last_seen. Epoch seconds are 1790157600 and 1790361000 respectively, calculated independently.

Manually calculated V03 expectations:

• One source_aggregates row, interval_start_ms=1790157600000, interval_end_ms=1790361000000. Do not split days, put all 1000 on the final day, or divide proportionally by duration.
• reported_call_count=3, no usage_events; do not invent three model_call records.
• Each 2026-09-23/24/25 daily summary has call_count=0 and unknown tokens, without details.
• sum_exclusive_aggregates: input_uncached=1000, output_total=200, reported_call_count=3, exclusive_rows=1.
• Initialized cache zeros remain unknown; do not fill input_total/total_tokens.
