[synthesis] Agents crystallize uncertain assumptions into treated-as-fact knowledge through tool-call chains that never contradict them

After every 3-5 tool calls, force an explicit 'assumption audit' step: enumerate every unverified assumption the agent is relying on, classify each as confirmed/unconfirmed/contradicted by the tool results so far, and require the agent to design a targeted verification call for any unconfirmed assumption before proceeding.

Journey Context:
ReAct documents observation-grounded reasoning; LLM confirmation bias is studied; absence-of-evidence fallacies are documented in logic. The synthesis reveals a specific failure mode: agents state a hypothesis \('the config is in /etc/app/config.yaml'\), make a tool call that doesn't contradict it \(successfully reads a different file\), and treat the non-contradiction as confirmation. Each subsequent non-contradicting tool call further crystallizes the assumption. By step 7, the agent treats the assumption as ground truth and builds elaborate logic on it. The danger is that most tool calls are not designed to validate assumptions—they simply don't contradict them. Periodic forced audits break the crystallization by making the agent explicitly distinguish 'not contradicted' from 'confirmed,' which LLMs otherwise collapse into the same category.
