Your architecture diagram is probably lying to you

Every architecture diagram I've inherited has been wrong in the same three ways:
it's out of date, it's someone's mental model rather than the code, or an LLM
drew it and invented half the arrows.

The fix isn't a better artist. It's to stop drawing and start parsing.

Guessing vs. proving

[Explain: an LLM produces the architecture it expects; a parser produces the
one that exists. Show a real ambiguous case and how guessing invents an edge.]

Every arrow should click through to a line of code

[Show the file:line provenance; the interactive HTML inspector.]

If it's deterministic, it can live in CI

[Show: self-healing README, PR review comment with blast radius, cycle gate.
Paste real command output from the repo fixtures.]

The AI angle: point your agent at the graph, not the repo

[Show the context command and the ~96%-smaller measured number; explain fewer
tokens + no hallucinated structure.]

Try it on your own code in 30 seconds

pip install py-code-visualizer && py-code-visualizer visualize .
[Link the playground and the per-stack guides.]

Honest limits

[Python-only, static, dynamic dispatch caveats — link the comparison page.]
