Turns out the tokenizer was seeing output as a token, which caused it to think if it closed the output tag, the output_list tag is also closed. The way we tokenize and generate embeddings has an outsize impact on the output consistency when it comes to rules.

The most fascinating thing I've worked on in the last 8 months building @isotopes_ai is how tokens are split and why that matters. We had a serious issue when asking a model to close XML tags </outputs_list> and </output>, which seemed very odd as it would "forget" the list tag.
