I’ve started studying low-level networking to understand full network behavior in depth. The clear conclusion so far is that a TLS fingerprint cannot be formed solely by BAS (Chromium). TLS fingerprinting also depends on system-level OS behavior, where the browser + OS + network stack + hardware timing together create the final observable fingerprint.
In this process, the protocol-level fingerprint (from Chrome/Chromium) stays consistent, but OS-level packet timing, TCP implementation, congestion control, jitter, and data buffering influence the actual TLS identity.
I do see one possible direction — but this would require building a larger ecosystem where the proxy environment can either emulate or preserve OS-level network characteristics. That’s ongoing R&D, and we’ll see how it evolves.
At least one confusion is now clearly resolved: as per my current knowledge, modifying only BAS (Chromium) to produce different realistic TLS fingerprints does not seem practically feasible unless the OS-level signals are also replicated or manipulated.
