[synthesis] Agent loops alternate between progress and regression, or diverge into tangents after 5\+ iterations without clear failure

Measure information gain per iteration; halt when entropy reduction < epsilon for 2 consecutive steps; require explicit 'state delta' output showing what changed

Journey Context:
Without a convergence metric, agents iterate based on 'feels done' heuristics or arbitrary step limits. Information-theoretic entropy of the context window reveals whether each loop reduces uncertainty \(converging\) or introduces new variables \(diverging\). When an agent adds more 'TODOs' than it resolves, or restates the problem differently without narrowing the solution space, entropy increases and further loops amplify noise. This synthesis reveals that agent loops are thermodynamic systems: they require negative entropy flow \(information gain\) to stabilize, and without explicit measurement, they naturally tend toward heat death \(circular reasoning\). The threshold is determined by whether the loop's output is added to context with 'epistemic markers' \(confidence, source, timestamp\) vs raw data. Explicit 'state delta' requirements force the agent to articulate what concrete progress was made, preventing the illusion of progress through rephrasing. This distinguishes between 'active reasoning' and 'circular reasoning.'
