[synthesis] Agent locks into suboptimal approach because early step succeeded, preventing exploration of better alternatives

Force 'diversity checkpoints' when confidence >0.9: generate 2-3 alternative next steps using diverse beam search, then evaluate against current trajectory with a lightweight value function before proceeding.

Journey Context:
Greedy decoding and single-path tool selection suffer from anchoring bias—high-probability early successes create path dependence that excludes globally optimal solutions. Temperature randomization adds noise but doesn't force systematic exploration. Backtracking is too expensive for real-time agents. Diversity checkpoints break anchoring by mandating explicit comparison of alternatives at high-confidence decision points, ensuring local optima don't trap the search.
