Answer

false
source_1
Coinbase BTC-USD historical candles: https://api.exchange.coinbase.com/products/BTC-USD/candles?start=2026-09-23T05%3A00%3A00Z&end=2026-09-23T06%3A00%3A00Z&granularity=3600
true_rule
Return true if the selected candle exists, is complete and its unrounded close is strictly greater than 87000 USD.
false_rule
Return false if the selected complete candle's close is less than or equal to 87000 USD. An intrahour high above the threshold is irrelevant.
instrument
Coinbase Exchange spot BTC-USD, quoted in USD per BTC. Do not substitute BTC-USDT, another exchange, a derivatives price or an aggregate index.
measurement
Use the 3600-second candle whose start timestamp is exactly 1790139600. The response row is [time, low, high, open, close, volume]; compare close at zero-based index 4. The API can return extra rows: do not use the first row without checking its timestamp.
version_policy
Use the provider's historical candle for this exact interval, not a current ticker. Record the retrieved row and retrieval time. If materially conflicting historical versions cannot be reconciled, flag inability. Archive the selected row before a funded-market settlement.
chain_window_role
The block window is a request anchor only. This is off-chain panel evidence. Resolve the event or measurement using the exact observation interval and rules above, not blockchain time or a rolling period.

unavailable_policy
Unavailable, incomplete or conflicting required evidence is not false. Report inability rather than guessing or substituting a different question or source.
