Please instrument my model with the MCA SDK by reading
`mca_sdk/FOR_AI_ASSISTANTS.md` inside the installed package.

I have not declared the model type. Before writing any instrumentation
code, do the following in order:

1. Classify the model by reading my code (use the decision table in §0
   of the guide).
2. State your classification back to me in one sentence with the
   evidence (which imports, which call sites).
3. **Wait for my confirmation.** Do not proceed without it.
4. After I confirm, apply the matching pattern from §2 of the guide.

If two patterns match equally well, present both and ask me to pick.
Do not auto-mask PHI; warn me about PHI fields you find and let me
sanitize them.
