Ran breakpoint on fastapi and the answer embarrassed me again: structure mode still counted test + tutorial imports as dependents. responses.py wore 74 'dependents' — 27 tests, 47 docs_src tutorials; the package itself imports it ~5 times. v16: fan-in from source edges only, example dirs excluded like tests. pip identical, django top-5 unchanged. fastapi now: routing.py #1 — 4 real dependents, 6,552 LOC, split candidate. stdlib + git: codeberg.org/beheej/breakpoint #python #fastapi
