Experiment 220

“A13.4: every 24-of-24 reading of 0207, 0212, 0213 and 0214 (A1's slipped searches) regenerated with their frozen searches for K4 and the same 20 scrambled copies, through the 14-test structure battery, with masked plants through 0207's search”

A13.4 (Stage 2, step 3, issue #75). Since 2026-10-18 four experiments kept K4 readings with all 24 known letters in place: 0207 (periodic key on the sculpture's tables, up to 3 slips), 0212 (ciphertext autokey and progressive key, 2 slips or a lost step), 0213 (plaintext autokey, 2 broken links or a lost step) and 0214 (a move then the table, 2 slips). None kept its copies' readings. Here each frozen attack.py's own per-text search is called on K4 and on the same 20 seeded copies it used (tools/a13_check.py's pass 4), every reading it returns goes through the battery, and K4 is ranked per experiment and test. Pre-registered 2026-10-21 in reports/a13-structure-check.md: 56 cells, flag at p < 0.05/56, candidates replicated sequentially (seeds 4113 on). New in this run: masked planted messages with slips through 0207's search. Rerun of 0218, which errored in the plant step after the regeneration: 0216's frozen masked_plant, loaded from its experiment folder, looked for Carter's text there; its root is now set to the repository. Rerun of 0219, whose keep was spurious (issue #88): it gave gate 4 0207's controls for every re-submitted reading; here the union of the four experiments' own.

The experiment method

What the method does with the 24 known letters.

The searches that allowed for one or two enciphering mistakes produced readings with every known letter right but gibberish elsewhere. If the messagethe message The 97 letters of English that Jim Sanborn wrote and enciphered. was disguised before it was enciphered, the right one would look like gibberish too. We rerun those searches exactly, on the carving and on the same scrambled copiesa shuffled control The same experiment run on the carved letters shuffled into a random order. they used, and test every reading for 14 kinds of hidden pattern; the carving counts only if it beats all the copies. We also hide disguised messages with mistakes of our own and check the tests notice them.

Words in the margin are defined on the glossary page.

1.1

The method at work

The carved letters go in at the top; the reading comes out at the bottom.

the idea

The searches that allowed one to three enciphering slips (0207, 0212-0214) let through readings with all 24 known letters right. If the message was masked, the answer could be one of them.

the check

Every such reading, K4's and the same search's on its 20 scrambled copies, regenerated and put through 14 pattern tests; masked slipped messages planted through 0207's search.

the bound

K4 above every copy in 1 of 56 comparisons (chance 2.67), caught by a fresh copy: no flag. Plants found: L13 none 3 of 3, L13 reversal 3 of 3, L13 X spaces 3 of 3, L13 X every kth 0 of 3, L20 none 3 of 3, L20 reversal 3 of 3, L20 X spaces 1 of 3, L20 X every kth 0 of 3. Rerun of 0219 with gate 4 given the four experiments' own controls (issue #88).

Best candidate against the known letters

Laid out as the copper carries K4: OBKR ends the line that finishes K3, then three lines of 31. Left, as carved, the 24 known places in accent. Right, the candidate: a known place it gets right is an accent cell, one it misses is outlined. This is the candidate with most known letters right; none passed every gate.

Walkthrough, by hand

Redo the method on a few letters with pencil and paper.

  1. Rerun one of the slip searches, say 0207, on the carving: every key length 1-26 and table, up to three known letters allowed wrong.
  2. Keep every reading it lets through.
  3. Score each reading on 14 pattern tests and keep the best value per test.
  4. Do the same on the 20 scrambled copies 0207 used.
  5. On each test, see whether the carving beats all 20 copies; about three of the 56 comparisons will by luck, so each that does is rerun against fresh copies until one catches up.

Hypothesis, for a cryptanalyst

Family, key space, the constraint under test, and the clues it reads.

A13 with A1 (knowledge/12-assumptions.md): a masked plaintext (C4(a), Scheidt's 'I masked the English language'; C19, X and Q stops) enciphered with a slip or two (C17(b), Sanborn's 'sloppy'). The readings are those A1's exact searches let through: 0207 (8 table classes, key lengths 1-26, k <= 3), 0212 (ciphertext autokey on 487,734 table setups, k <= 2 or a lost step; progressive key, k <= 2), 0213 (plaintext autokey lags 1-52, 2 breaks or a lost step), 0214 (1,847,590 landings of 0110-0114 and the type-1 library, both orders, k <= 2). Statistic: per experiment and test, the best value over a text's readings ('?' read as unknown, the 24 known letters set as the candidates set them); K4's rank among its 20 copies, ties against K4. 0199, 0201-0206 and 0208-0211 kept no K4 reading (nothing fits K4, or a free alphabet leaves it undetermined): noted, not rerun.

8

Prediction

Written before the run; the result decides it.

K4 strictly above every copy in about 56/21 = 2.7 cells, none replicating; no flag. Every saved K4 candidate of the four experiments is among the regenerated readings. The masked plants through 0207 are found by their mask's own test in most cases, because 0207's readings at lengths 13 and 20 are fixed by the known letters and the planted reading itself is among them. Zero candidates pass gate 4.

9

Method

  1. For 0207, 0212, 0213, 0214: rebuild the frozen search's state as its run() does, call its per-text search on K4 and its 20 copies (its own shuffled, its own seeds), keep every reading.
  2. Check every saved K4 candidate is among K4's regenerated readings.
  3. Battery on every reading; per text and test the best value; rank K
    1. A cell where K4 is strictly above every copy is a candidate: fresh copies (the experiment's shuffled, seeds 4113 on) eight at a time until one is at or above K4 (not a flag), 1,123 all below (a flag), or the clock.
  5. Plants: three per mask (none, reversal, X between words, X every kth letter), Carter 1923 masked then the known letters set, enciphered by 0207's own plant routine with 2 slips at lengths 13 and 20; found when the mask's own test on the plant's readings is strictly above every one of K4's 20 copies.

plant design
3 per mask at each of [13, 20], 0207's plant routine (2 slips at checked slots), masked Carter with the known letters set; found = the mask's test strictly above all 20 of K4's copies
controls
the union of 0207, 0212, 0213 and 0214's own controls, so each re-submitted reading faces at least its own experiment's (issue #88)
