GoldSrc (HL1 engine) is very much not open source (or even source available). There's at least one open source remake (which is possibly illegal due to using the SDK) but no official release.

https://github.com/ValveSoftware/halflife is the HL1 engine, is it not?
That's just the SDK - which does include the game code but not the engine. Xash3D is the reverse engineered engine alluded to above.
