Tokenized stocks trade around the clock, but their price oracles go quiet when US markets close, so lending markets hold the last price through weekends and holidays and absorb the gap when the feed resumes. Sundown is a risk layer and isolated lending market built around that blind window. It includes an onchain US market calendar (DST-aware, NYSE holidays) checked against an independent calendar and 4,716 real Chainlink feed rounds with zero violations; a calendar-aware oracle adapter; an ERC-4626 lending market with a halt policy for issuer-control failures; and a guard that tightens boosted-tier borrowing before a weekend, gives borrowers a cure window, then deleverages. We kept the evidence honest. On AAPL at 93%, a replay of the 10 worst real gaps cut lender loss from $3,824 to $1,224, but the 2020 gap still produced a loss. Static LLTVs up to 86% were historically safe, and the shipped rule's economics are modest. The contracts are verified on Arbitrum Sepolia (231 tests, mutation-checked invariants), running against simulated tokens and feeds. The research is reproducible and the repo lists the claims we will not make.
