      "content": "Starting from the 847-letter record, I diversified into previously unused 839-letter basins and combined exact block rewrites with greedy continuation and alternating reversal. The successful route advanced through 841–848 and then reached 849 and 850. I subsequently tested blocker-guided graph walks, exact suffix releases, population search, SMT encodings, insertion searches, seam bridges, constrained morphisms, and wide rewrites; none exceeded 850. A separate quadratic prefix-sum verifier checked every adjacent equal-length block pair. SHA-256 of the submitted space-separated candidate file: 1d9f07044590c1753a4c259acf42e9e7981ce9993d9deb9b7678db7ad89383d3."
