Introduces the Token-In-Token-Out (TITO) design principle in the Miles RL framework: three common failure modes (detokenize-retokenize mismatch, chat-template cut-thinking, lossy re-rendering) and the four-component implementation (inference session server, append-only enforcement at three levels, pluggable TITO tokenizer with per-model splice-point patches, and a token-sequence comparator with CI verification).

(only the
toolrole is supported for v4)
I think it is strange to put this note here. Consider moving it below.

| For each model, TITO is verified to handle the following combinations of message roles a harness may append after the first assistant turn: |

Perhaps note "(except Deepseek-v4)" here.

| Deepseek-v4 currently supports only the `{tool}` surface. | ||

| Adding a new model is usually a fixed Jinja template plus a small [`merge_tokens`](https://github.com/radixark/miles/blob/3270915550fcd69dce788f382fa8c12548a63618/miles/utils/chat_template_utils/tito_tokenizer.py) override. |

- Combine this with the previous paragraph.
- Should convey the idea that supporting a model is easy.
- Currently it feels that the blog post is cut off. Make the blog post properly ended.
