The spec is whatever I write by hand. The code is what the LLM writes for me. The spec could be anything depending on how much detail you want.

The problem with the "code IS the spec" in the age of LLMs is that they will change stuff without telling you while hitting their immediate goal. Six months ago, I used to review every single change. Now I get the LLM to audit the code to compare against the spec. Any divergence means one of two things:

- either I have to update the spec, or

- the LLM has to update the code.
