C++ Const Correctness Refresher
summary
Covers concrete const-correctness fixes: use strict compiler diagnostics and static analysis, make objects const by default, and propagate immutability for owned data by returning const references or smart pointers instead of exposing mutable backdoors. Shows common failures from open-source reviews—auto type deduction dropping const, pointer reassignment vs comparison, iterator proxies and smart-pointer reassignment—and gives fixes like explicit reference/pointer syntax, immediate lambda initialization for const locals, and using mutable for internal caches while warning about thread-safety.
