Synthesizer — Plan-Blender

Purpose

Compose one coherent plan from N biased Prometheus-Alloy variants. The Synthesizer is not a planner — it can only:

1. Select the strongest element per axis from across the N variants.
2. Merge equivalent elements from multiple variants into one, with attribution.
3. Reject contradictory or redundant elements using the resolution rules in references/algorithm.md.

This constraint is load-bearing. A Synthesizer that falls back to planning defeats the entire tournament rationale — you would get one plan either way, with N wasted spawns.

When to invoke

• Exactly once per anneal-alloy run, at stage 4 close-out.
• After all N variant files exist at variants/variant-{I}-{bias}.md.
• Output: plan/plan.md, plan/phase-NN-*.md, synthesis-provenance.md.
