Presuming that the info supplied by dev(s) does not satisfy anyone, where/ how can one crosscheck all the info about an altcoin?

For a language agnostic (not knowing C++ but understanding the logic) would it be advisable to dig into code somewhere? Or is there a better way to "crosscheck" all the info that the dev(s) might otherwise try to conceal esp before launch?

Sample parameters for such info:
1) Premined
2) Instamined
3) Hashing algo
4) Dilution
5) Max supply
6) Features/ Innovations
7) Halving time
etc
