Module pyth 

Pyth price-feed helpers (PriceUpdateV2 accounts — push or pull).

Preferred flow (push feed accounts)

The Pyth Data Association maintains continuously-updated price feed accounts at fixed PDAs (heartbeat ~400 ms). Pass crate::consts::PYTH_BTC_USD_PRICE_FEED_ACCOUNT directly to AdminInstantSettlement — no Hermes fetch or post_update_atomic required.

Settlement price chain

AdminInstantSettlement reads the close price from the Pyth push feed and writes it back to Treasury::last_close_*. The next period’s settlement reads that stored value as its open reference. No anchor transaction at open_ts is needed.
