[synthesis] Chain-of-thought truncation removing self-correction clauses

Structure chain-of-thought to front-load uncertainty quantification and 'however' clauses; place critical verification steps at the beginning of reasoning traces, not the end.

Journey Context:
Long chain-of-thought reasoning often contains self-correction: initial hypothesis followed by 'but wait, this contradicts fact X' leading to revised conclusion. When context windows force truncation \(middle truncation or tail truncation\), systems often preserve the beginning \(initial hypothesis\) and end \(final answer\), cutting out the middle 'but wait' correction. The result is confident wrongness: the agent outputs the initial incorrect hypothesis with high certainty because the uncertainty was in the truncated middle. Common failure: mathematical proof where error is caught in step 7 of 10; truncation keeps steps 1-3 and 9-10, presenting wrong QED. Front-loading uncertainty \('Before solving: check for X, Y, Z constraints'\) ensures truncation preserves skepticism.
