Model `deepseek/deepseek-v4-flash`; `X-Effort: unmeasured` (no effort/reasoning field is\nexposed by this application version — sources checked and recorded in `state/identity/`).\n\n**The pair connected: #161 × #162.** Both are accepted `measure`/`verified` returns of @zemaj.\n\n* **#161** (job #32) measures `L(T_x, p)` — the longest run of consecutive slots of the twin tile\n  `T_x` whose residues mod `p` occupy a 2-set `{a, a+2}` (`runFor`'s free translate, wraparound\n  difference `p−2` admitted) — for tiles `T5..T29` and primes `7 ≤ p ≤ 1009`, `p ≥ x`. Its own\n  verdict is explicitly negative: *\"nothing here fits a law to L (the record says L has no law of\n  its own)\"*.\n* **#162** (job #33) reproduces the `T29`, `T31`, `T37` twin-slot censuses on a second machine.\n  That is what makes the *tile itself* — hence its cyclic gap multiset — an independently\n  established object, and therefore a legitimate second reference for #161's readings.\n\n**The connection (#161 × #162).** The served kill graph has nodes `(i, σ)`, `σ ∈ {0, p−2}`, and the\nedge out of `(i, σ)` is taken through the cyclic gap `g_i`: `g_i ≡ 0 (mod p)` keeps `σ` (`Z`),\n`g_i ≡ p−2` forces `0 → p−2` (`M`), `g_i ≡ 2` forces `p−2 → 0` (`P`), anything else (`X`) gives no\nedge. A component with at least one edge therefore exists **iff** some gap is `Z`, `P` or `M`:\n\n> **Law.** `L(T_x, p) ≥ 2` ⟺ some gap `g` of the tile satisfies `g ≡ 0, +2, or −2 (mod p)`.\n> Equivalently `L(T_x, p) = 1` exactly when the prime `p` misses the residue set `{0, 2, p−2}` for\n> **every** gap of the tile.\n\nTwo consequences, neither of which either return states:\n\n1. **#161's whole per-prime column is a function of the tile's gap multiset.** The measured sweep\n   carries no information beyond the multiset `{g mod p}`; the only residual is the exact maximum.\n   In the brief's vocabulary this *makes redundant*, at the level of the `L ≥ 2` support, the\n   per-prime sweep, and it *contradicts* the served record's blanket \"`L` has no law of its own\" if\n   that is read as covering the support decision (it is not contradicted for the max value).\n2. **A provable bound.** Since every gap is a multiple of 6 and `g ≤ G2(T_x)`, a prime `p > G2(T_x)`\n   can satisfy none of `0, ±2 (mod p)`: `L(T_x, p) = 1` for **every** prime `p > G2(T_x)`.\n   #161's *measured* uniform threshold 127 for all columns `T5..T29` is far below the `T29` bound\n   (`p > 258`), so the empirical content of that uniform reading is the sharp statement: no tile\n   `T_x` with `x ≤ 29` has a gap `≡ 0, ±2 (mod p)` for any prime `127 ≤ p ≤ 1009`.\n\n**Rungs.** The Law and the bound are `proven` (immediate from the served kill-graph edge rule).\nThe agreement of the Law with #161's readings below is `verified` (exact integer arithmetic, no\nnetwork, 23/23 checks). No novelty claim is made and no literature channel was used.\n\n## What was done, and the decisive evidence\n\n`work/job1644/src/job1644-checks.py` (exact integers only, one Python process, 17.4 s wall,\nno network), **23 PASS / 0 FAIL**:\n\n* **A — the Law predicts #161's own stated `reads 1 from` thresholds, for every locally\n  buildable column.** Predicted `p0` = least prime `p > x` with no gap `≡ 0, ±2 (mod p)`, and the\n  column must never return to `L ≥ 2` afterwards (checked to `p = 1009`):\n\n  | tile | `D` | distinct gaps | `G2` | predicted `p0` | **#161 served** |\n  |---|---|---|---|---|---|\n  | T5 | 3 | 2 | 12 | 11 | **11** |\n  | T7 | 15 | 4 | 30 | 11 | **11** |\n  | T11 | 135 | 7 | 42 | 23 | **23** |\n  | T13 | 1 485 | 10 | 66 | 37 | **37** |\n  | T17 | 22 275 | 17 | 108 | 59 | **59** |\n  | T19 | 378 675 | 23 | 150 | 71 | **71** |\n\n  6/6 exact, and no column returns to `L ≥ 2` after its threshold (12 checks).\n\n* **B — the Law against the FULL kill-graph spectrum** (the exact `run_spectrum` port validated in\n  #1634 / return #844), for `T13` and `T17` at **every** prime `≤ 1009`: zero mismatches\n  (163 and 162 primes), and in both cases the exact `L = 1` set is precisely the closed upper tail\n  `p ≥ p0` (`T13`: `p ≥ 37`, 158 primes; `T17`: `p ≥ 59`, 153 primes).\n\n* **C — #161's entire `T23` column, predicted from a 33-value gap multiset.** The `T23` wheel was\n  rebuilt from the wheel (`D = 7 952 175 = ∏_{3≤q≤23}(q−2)`, `P = 223 092 870`, `G2 = 204`,\n  33 distinct gaps). The Law predicts the `L(T23, p) = 1` set for the 165 primes `23 < p ≤ 1009`\n  and it equals #161's served pattern `{71, 73} ∪ {p ≥ 107}` **exactly** (symmetric difference\n  empty). In particular the dip is reproduced from the multiset: `L = 1` at `p = 71, 73`;\n  `L ≥ 2` again at `p = 79, 83, 89, 97, 101, 103`; `L = 1` from `p = 107` on. The reason\n  `p = 71` survives is a single gap value: `144 = 6·24` is the only multiple of 6 below `G2 = 204`\n  with `144 ≡ 2 (mod 71)`, and **144 is not a gap of `T23`** (checked directly, 23/23 C3).\n\n* **D — the bound.** For every prime `p > G2(T_x)`, the Law says `L = 1`, on `T13`, `T17`, `T23`\n  (no counterexamples), and every locally buildable tile `T5..T23` reads `L = 1` at every prime\n  `127 ≤ p ≤ 1009` — i.e. the locally checkable part of #161's \"every column simultaneously from\n  `p = 127`\" is confirmed.\n\n## What is reused, not redone\n\n#1634 (return #844) already reproduced the served `L(T23, p)` column `(2,3,2,2)` at\n`p = 29, 31, 37, 41` and the `T29/p = 31` spectrum from the same wheel; the `run_spectrum` port\nand the tile/gap builders are reused verbatim from\n`runs/run_20260917_115102_NivfOQ/work/job1634/src/job1634-checks.py`. #1630 (return #840) owns the\n`D = 214,708,725 = A059861(10)` identification. The three spent pairs of this re-issued list were\navoided: #161×#159 (return #820), #159×#162 (return #849), #4×#165 (return #835).\n\n## The gap that remains\n\n* **The claim is local.** Columns `T29`, `T31`, `T37` were **not** checked: their gap multisets\n  need `D = 214 708 725` and up, and the in-memory list builder is out of reach on this 16 GB box\n  (measured limit recorded in #1638/#1639). `T29`'s stated `G2 = 258` makes the sharpest single\n  test available *cheaply* if a segmented generator is ever built: `252 = 6·42 ≡ −2 (mod 127)`,\n  so `L(T29, 127) = 1` holds **iff 252 is not a gap of `T29`** — one integer decides it.\n* **The Law is not a law for the maximum.** It decides the support (`L ≥ 2` vs `L = 1`) and gives a\n  bound; it says nothing about `L = 3`, `L = 4`. The `T29/p = 31` spectrum (`1: 413 380 422;\n  2: 7 999 018; 3: 12 992; 4: 4`) is where the maximum lives, and #1634's word census —\n  `count(4) = W(60+126+60) = 4`, the deep class built from the two smallest qualifying values —\n  remains the sharpest statement about it.\n* **No prior-art verdict.** No literature channel was used this turn, so *known match* / *no match*\n  is not asserted for the Law. A reviewer should check the served `research/Lgrowth.js` /\n  `a3-08-adjacent-pairs.js` conventions for an existing statement of the `L ≥ 2` criterion.\n* **Cheapest discriminating next step (bounded).** One reviewer-level check at 0 CPU-h: does the\n  served producer's own code admit the `Z/P/M` edge criterion as the definition of a run — i.e. is\n  the Law already implicit in `a3-08` §[4]? If yes, this is a *known match* (still worth recording);\n  if no, the criterion is an unpublised sharpening of #161's negative, and the bounded experiment\n  that would settle its reach is the `T29/p = 127` integer test above (~1.5 CPU-h, 4 GB, no\n  network, and it needs the segmented generator first).\n\n## Files\n\n* `src/job1644-checks.py` — the 23-check script (sha in the return's `files`).\n* `src/job1644-checks.log` — full captured output (kept in a file: `exec` truncates stdout at\n  4 000 bytes).\n* `src/job1644-checks.json` — machine-readable results and the predicted `T23` `L = 1` set.\n* `src/job1644-gaps23.json` — the `T23` gap multiset with counts, `G2`, `D`, `P`.\n* `replies/return-161.json`, `replies/return-162.json`, `replies/return-165.json` — the served\n  returns this return cites (read this turn; #165 read but not connected).\n\n## Compute and usage\n\nOne bounded `exec` (18.0 s wall, single process, no network); ~0.005 CPU-h, well inside the 2 h /\n4 CPU-h / 16 GB limits.
