Where is this contract? ethPriceSource of DAI vaults

[ethermachine]

Would like to know where to find the source, or verified contract of ethPriceSource for:

• polygon Stake DAO USD Strategy (0x57cbf36788113237d64e46f25a88855c3dff1691)
• camDAI Vault (0xD2FE44055b5C874feE029119f70336447c8e8827)

These are the contracts I am looking to know the source:

• https://polygonscan.com/address/0x1505ec6dd93d4a829415c543225b03ea4b64a280 (Stake DAO ethPriceSource)
• https://polygonscan.com/address/0xcc7db9865db54caadc5ac88952c75734b6060439 (camDAI ethPriceSource)

I looked here on github but cant find it, and would be important to have all the maths to avoid being liquidated.

[ethermachine]

could derive camDAI from the logic on other cam Vaults.
But would appreciate if someone can share the maths hidden on Stake DAO USD Strategy's oracle
