Call `passiveTPPEngine?.processPoll(current:previous:)` + +The previous poll is already fetched inside `persistPoll()` (line 70), but it's not returned. Two approaches: +- **Option A (preferred):** Query `getLastPoll()` BEFORE the new poll is inserted. Since `persistPoll` already does this internally, the engine can do the same query before calling persistPoll. +- **Option B:** Get the two most recent polls from DB after persist and use the older one as "previous." + +**Use Option A:** In the PollingEngine fire-and-forget Task, query `getLastPoll()` before `persistPoll()`, then after persist, create the "current" poll from the response and pass both to the passive engine. + +**IMPORTANT:** The passive engine must receive the poll timestamps, NOT `Date()` — use the same `Int64(Date().timeIntervalSince1970 * 1000)` pattern as `HistoricalDataService.persistPoll()`. + +### Reset Detection in Passive Engine + +The passive engine uses a SIMPLER reset detection than `HistoricalDataService`: +- Just check: `previous.fiveHourUtil - current.fiveHourUtil >= 50` +- No `resets_at` timestamp comparison needed -- the engine only cares about large utilization drops, not the exact reset mechanism +- This is consistent with the epic spec: "5h utilization reset is detected (utilization drops by >=50%)" + +### Confidence Assignment Logic + +| Condition | Confidence | +|-----------|-----------| +| Single model, 5h delta >= 3% | `medium` | +| Single model, 5h delta 1-2% | `low` | +| Multiple models in window | `low` (always) | +| Delta-only record (no tokens) | `low` | + +### TPP Computation + +```swift +let tppFiveHour: Double? = fiveHourDelta >= 1 ?
