Report #45242

[synthesis] Premature plan commitment where sunk cost reasoning prevents replanning after early errors

Implement hierarchical planning with explicit rollback checkpoints; validate subgoal achievability before committing resources, not after.

Journey Context:
Agents with planning capabilities often commit to high-level plans early based on incomplete information, then experience 'sunk cost' effects where subsequent steps attempt to salvage the flawed plan rather than triggering expensive replanning. The common mistake is linear planning without rollback points. The fix uses hierarchical planning \(options in HRL\) with explicit checkpoint validation before resource commitment. Alternatives like continuous replanning fail due to computational cost and instability; the correct tradeoff validates feasibility before commitment.
