Exercise: EX-12 — The analyzer audit · difficulty 🟡

What this exercise asks

Read the exercise first; this thread is for when you are stuck, not instead of it.

Three ways people get stuck on this one

1. Auditing the tokenizer on prose only. The failure lives in identifiers, versions, paths and error codes — that is #1.

2. Adding . to tokenchars, which stops sentence-ending periods separating tokens and breaks far more than it fixes.

3. Not measuring per-class afterwards, so the fix cannot be shown to have worked.

How to ask here

Post the numbers you got, the config that produced them, and what you already tried.
A question with a measurement in it gets answered in one round trip; a question without one
takes three.

If you have finished it, post the write-up in Show and Tell with the
[solution · EX-12] prefix rather than here — this thread stays for people who are stuck.
