  - 1,953 components extracted
  - 17,505 typed dependencies mapped (not just "A calls B" — ownership, injection, weak ref, circular, etc.)
  - 25 architectural blocks detected automatically
  - 498 architectural smells found
  - 116 dead code detections
  - 100% classification consensus (zero ambiguous)

  Component distribution:
    Core logic:    425 (21.8%) — app, router, route objects
    Terminals:     744 (38.1%) — constants, test assertions
    Helpers:       346 (17.7%) — utility functions
    State stores:  313 (16.0%) — express, request, Router, factories
    Features:      110 (5.6%)  — test-specific app instances
    Middleware:     10 (0.5%)  — andRestrictTo, sendfile
    Entry points:    5 (0.3%)  — users, restrict, getCookie

  Architectural problems detected:
    CRITICAL: 532 components in circular dependency chains
    ERROR: God Class — `app` has 67 outbound dependencies
    ERROR: God Class — `router` has 83 outbound dependencies
    Stateful services at 0% health (critical coupling)

  Cross-cutting concerns found automatically:
    trust proxy logic in request.js (8 components)
    response callback chain: onend, onaborted, onerror, onfinish
    pure functions — 71 components, 93% health
    boundary validators — 98% health

  All of this is known to be true by anyone who's worked on Express.
  The God Object pattern in `app` is a documented community concern.
  The circular deps between app↔router↔request↔response are well-known.

  Happy to run it against any public repo if you want to suggest one.
