Current detection is strong for translation-unit-local mistakes, but it is not whole-program unused-code detection. The two PRs expose different gaps, so no single extra compiler flag will solve both.

Mechanism	Currently catches	Main gaps
Compiler warnings + -Werror	Scalars, internal functions, some private members, unreachable code	Non-trivial value objects; public/external/virtual methods; unused parameters intentionally disabled
clang-tidy	Unused using declarations, selected ignored return values	No configured non-trivial-local or cross-TU dead-declaration check
IWYU	Unnecessary includes in an enforced subset	Not functions/types; much of wallet, tests, fuzz, Qt, and IPC is non-enforcing
Ruff/ShellCheck	Python imports/locals and shell variables	Python functions/classes; C++ declarations
LTO/dead stripping	Removes unreachable emitted code in selected builds	Does not fail CI, misses source-only code, and vtables can retain unused virtual methods
