ob_ai_call is the only input to V2 pricing, and it was dropping the two numbers needed to interpret its own cost column. tokens_reasoning was captured from the provider response but never written to the table, so the cost of thinking mode was invisible once it left the process. Folding it into tokens_out was not an option either -- it is billed at the output rate, and mixing the two hides exactly the difference we now have to watch. rate_tier records which price list applied. Without it a row's cost_cents cannot be rechecked: DeepSeek's peak rate is double off-peak from 2026-08-17, so recomputing an old row at "the current rate" silently produces a different answer than what was actually billed. Migration 0002 adds both columns. tokens_reasoning defaults to 0 rather than NULL so cost aggregates do not collapse to NULL on historical rows; rate_tier stays nullable because rows written before this change genuinely have an unknown tier, and NULL says that more honestly than a guessed 'flat'. The smoke script now asserts both: reasoning tokens must be 0 (a non-zero value means a provider default re-enabled thinking mode behind our backs) and rate_tier must be present. Verified against the real API -- tokens_reasoning=0, rate_tier=off_peak, 3.9s round trip.
