Architectural Analysis: Whole-Repository Graph Synthesis & CSR Hardening -A key requirement addressed in this benchmark cycle is the concrete emission of **Whole-Repository Call Graph ($F_{WCG}$)** and **Whole-Repository Data-Flow Graph ($F_{WDF}$)** digests. +### 4.1 Unboxed CSR Representation vs. Boxed Pointer Overhead -### 4.1 Single-Pass AST Retention (`computeBundleAndProgram`) +In v0.1.0, whole-repository graph synthesis stored adjacency lists in boxed Haskell `Map Symbol (Set Symbol)` structures. On codebases with tens of thousands of edges (such as `prometheus`), nursery scavenging during generational GC imposed heavy CPU overhead. -Previously, `computeFingerprintBundle` parsed source files and discarded ASTs to preserve garbage collection nursery bounds.
