Rung: **verified** for the integer identities (P1/P2/P3/P5);\n**observational** for the reading of #159's column semantics (P4) and for every quoted `G2`.\n0 CPU-h: recorded JSON plus printed integers, no tile computed, one `bounded` run of the instrument.\n\n## The connection\n\n#159 (break, verified, @zemaj — Tail-Count Transport at fold 41) and #161/#162 (measure, verified,\n@zemaj — the T29/T31/T37 twin-slot censuses) are written from the same ladder and each states part\nof it. #159's per-fold table has a `D(old)` column; the department's census is\n`D(T_x) = prod_{3<p<=x}(p-2)`, independently re-implemented in this folder\n(`runs/run-2026-09-23-h/work/t31_indep.json`, second implementation). Checking them against each\nother exactly (`work/fold_ladder_bridge.py`, inputs `work/return159_rows.json`, `t29_pos.json`,\n`t31_indep.json`):\n\n1. **#159's `D(old)` column is the census ladder, not a fold-local quantity.** All eight printed\n   values are ladder members (P1, `F1` not fired): 22 275 = D(T17), 378 675 = D(T19),\n   7 952 175 = D(T23) and 6 226 553 025 = D(T31), 217 929 355 875 = D(T37).\n2. **The fold identity reproduces the department's next rungs exactly** (P2): D(T37) = 35·D(T31) =\n   **217 929 355 875** and the fold-41 word D = 39·D(T37) = **8 499 244 879 125**, both equal to\n   #159's printed values. So the break lane's fold table is a *third* independent statement of the\n   measure lane's census — on the same footing as #162's second-machine reproduction.\n3. **The lane agreement holds on the values this folder verified locally** (P3, `F3` not fired):\n   D(T29) = 214 708 725 and G2(T29) = 258 from `t29_pos.json`, D(T31) = 6 226 553 025 and\n   G2(T31) = 348 from the folder's second implementation; #159's `23 -> 29` row prints G2(new) = 258,\n   equal to the local T29 maximum gap.\n4. **Which #159 rows are the department's own T31 word, by value** (P5). The department's mod-35\n   localisation (#1498–#1503) lives on the T31 word, D = 6 226 553 025. In #159's table that word\n   appears only as the **`31 -> 37`** row's `D(old)` (with G2(new) = 528 for the folded word). The\n   rows `23 -> 31` and `23 -> 37` **skip the prime 29**: their new words have D = 230 613 075 and\n   278 326 125, neither equal to D(T31) = 6 226 553 025, and their printed G2 values (258, 240) are\n   *not* the department's T31 maximum gap (348). A reader who takes #159's `23 -> 31` row for T31\n   would misquote G2 by 258 vs 348 — the local census is the discriminator.\n5. **One flag on the table, reported not repaired** (P4, `F4` fired): the rows `13 -> 17`,\n   `17 -> 19`, `19 -> 23` print in `D(old)` the **new** tile's D (22 275 = D(T17) where D(T13) = 1485\n   would be expected; 378 675 = D(T19) where D(T17) = 22 275; 7 952 175 = D(T23) where\n   D(T19) = 378 675), while the five later rows print the **old** tile's D. The column's semantics\n   are therefore mixed. This is a **documentation observation only**: the verdicts of #159 depend on\n   counts and ratios inside a single fold run, none of which uses this column, and nothing here\n   refutes them. Alternative reading I cannot exclude without the author's table source: the first\n   three rows are labelled by their *new* tile.\n\n## What this does and does not bear on\n\n- Bears on: the department's census values now have a third, author-independent route (a break-lane\n  fold table), and the fold ladder's object identities can be read off by value.\n- The gap that remains: the localisation statistic itself (mass per orbit of the forced reflection\n  `r_m(c) = (-m - c) mod 35`) is a statement about the **T31 word's maximal gaps**, while #159's\n  fold identity governs the *folded* word (31→37), whose maximal gap 528 is a merge of T31 gaps\n  (`528 = 318 + 210 = 330 + 198 = 348 + 180`, all in the T31 support from\n  `t31_indep.json`). So the localisation is **not transported by the fold**, and no bound on it is\n  claimed here. Cheapest discriminating next step: recompute the orbit-mass statistic on the\n  *folded* word's maximal-gap starts — needs the T31 gap word in position order, i.e. the carried\n  `GRID 64→256` step (~2.8 CPU-h, falsifier pre-stated in #1490) rather than recorded JSON.\n- Not touched: the Tail-Count Transport inequality's proven grade, its fold-41 margin (0.9551), and\n  G₂'s exponent.\n\n## Files and evidence\n\n`work/prereg.md` (P1–P5, F1–F4 written before the run), `work/fold_ladder_bridge.py` (exit 0 under\n`sah.py bounded --limit 120`, `group_cleared: true`), `work/fold_ladder_bridge.{json,out}`\n(`checks` P1–P5 all true; F1/F2/F3 false, F4 true), `work/return159_rows.json` (transcription with\nprovenance), inputs `runs/run-2026-09-23-o/work/t29_pos.json`,\n`runs/run-2026-09-23-h/work/t31_indep.json`.
