Misspelling-derived tableau reconstruction

From five misspelled-letter swaps

In plain English: From five misspelled-letter swaps, using a method based on non-standard or physically-inspired methods. 364 thousand key/parameter combinations were tested. This record is negative within the tested scope.

NOISE Tier 3

How to read this record

Verdict – ELIMINATED (ruled out within the tested scope), NOISE (nothing beyond what chance produces for a search of this size; also shown when a record stored no verdict of its own), INCONCLUSIVE (the test left candidates or options standing, or could not decide, so it does not rule the method out), INTERESTING (slightly above random, almost certainly coincidence), SIGNAL (statistically unusual, warrants investigation), or FULL MATCH (all 24 known letters correct).
Confidence Tier – Tier 1 = mathematical proof, valid while its stated assumptions hold. Tier 2 = every possibility within the stated scope tested. Tier 3 = partially tested or sampled. Tier 4 = not yet properly tested.
Configs Tested – How many different key/parameter combinations were tried.
Best Score – How many of the 24 known plaintext letters the best attempt matched (out of 24). N/A means no such score could be read from this record.
Keystream Consistency (Bean) – Whether the key values at different positions are mathematically consistent with each other. The check only holds when the known letters stay in their carved positions (no letters rearranged or removed), and the full set used here assumes the standard A to Z alphabet.
Scope Limitations – What this elimination does not rule out.

Configs Tested: 363,726
Best Score: 8 / 24 known letters matched · low, no sign of a solution
Confidence: Tier 3: Partial or statistical. May warrant re-testing under different assumptions.
Date Tested: 2026-02-20

Scope Limitations

This elimination does not rule out:

Only tests tableau changes built from five letter swaps (S to C, L to Q, O to U, E to A, I to E). The O to U swap comes from UNDERGRUUND, which was a carving error, not a deliberate change. The running-key part used copies of the K2 and K3 plaintexts that stop matching the real texts (K3 after 44 letters, K2 after 115), so most of its running-key tests did not use the real texts. Does not eliminate arbitrary tableau modifications.

Assumptions

Test hypothesis: the misspelled letter pairs encode tableau column shifts or substitutions

Reproduce
