ZOMBIE CODE DETECTION
The dead code your scanner swears is alive.
Zombie code compiles, imports cleanly and calls itself in a tidy little loop — and no entry point in your app ever reaches it. Mapnostics builds the call graph, walks it from every real entry point, and hands you the whole orphaned cluster to delete.
Reachability, not reference counts
A dead-code scan stops when every function has a caller. Zombie detection keeps going — it asks whether anything outside the cluster ever calls in.
The whole chain, named
Every finding shows the call chain behind it, so you delete the orphaned group in one commit instead of breaking the next function along.
Feature flags included
A flag hard-off for a year is the most common zombie. Mapnostics splits flags into decided-in-code and set-at-runtime, so you know which are safe to act on.

Common questions
What is zombie code?
Code that runs but for no reason: it is reached only by other unused code, so the whole cluster is effectively orphaned even though each piece looks referenced.
How is zombie code different from dead code?
Dead code is never executed because nothing references it. Zombie code is executed, but only by other unreachable code. A scanner that only checks "is this referenced?" misses it.
How does Mapnostics find zombie code?
It walks the call graph from every real entry point — routes, pages, jobs, CLI commands — and reports the connected clusters that nothing reachable ever enters.
