Study H · Interface reliability
The crossover, found: above ~300 nodes, only anchored patches hold
300–1000 nodes
Study Overview
Rewrite Hits a Ceiling
Whole-tree rewrite becomes frontier-only at scale (gemini-flash: 0/15 at ~1000 nodes; sonnet needs a streaming transport and ten minutes per rewrite).
Anchored Patches Hold
Anchored patches hold 87–100% for both tiers at every size; $0.26 and 4 seconds per solved 1000-node edit.
Positional Patches Collapse
Positional patches decay to ~10%. Solid lines: sonnet-4.5; dashed: gemini-3.5-flash.
