UnifiedCovariant.lean: layer_2d_yang_baxter_holds (a re-export of the deleted X=X tautology, using the removed B) replaced by layer_2d_braid_relation := braid_relation_S8; the false YB-integrability-by-alpha-equivalence docstring corrected. lakefile.lean: register SilverSight.PIST.SidonMirrorNotch. Full lake build of the chain is green (3300 jobs); remaining sorry warnings are pre-existing Layer-3 geometric-conjecture stubs, not introduced here.

YangBaxter.lean: the prior `yang_baxter_holds` was `rfl` over two alpha-equivalent
sums (literally X = X); even the intended R = B(x)B claim satisfies YBE vacuously
(B^2(x)B^2(x)B^2 on both sides, for any B). An exact rational search (ybe_sidon.py,
ybe_verify.py) showed the Sidon block admits no invertible, non-triangular R-matrix.
Replaced with `braid_relation_S8` -- the honest symmetric-group (S_n image of B_n,
Artin 1947) braid relation as a concrete 8x8 permutation-matrix identity, by `decide`
-- plus `braid_relation_falsifiable`, a negative control proving the statement is not
vacuous (a non-permutation gate breaks it). Both axiom-clean: no sorryAx, no
ofReduceBool (genuine kernel `decide`, not native_decide).
SidonMirrorNotch.lean (new): the mirror-projection spine, written from scratch (no
such file existed despite being cited). Mirror involution tau(a) = S - a, the
observerless difference-invariant, and the notch congruence
a == S - a [ZMOD l] <-> l | (2a - S).
Both files verified standalone via `lake env lean` (elan toolchain v4.30.0-rc2).
Known follow-up (next commit): UnifiedCovariant.lean re-exports the deleted
`yang_baxter_holds` and must be retired for a green full `lake build`.

1. bms_implies_sieve: swap 'decide' for 'norm_num', reorder interval_cases
to chunk by m first (~89 x-values per dispatch instead of 979 monolithic).
2. sieve_discriminates: delete broken version (confused repunit values with
bases), promote sieve_discriminates_correct as canonical.
3. rrc_characterizes_goormaghtigh: add BMS bounds to signature, add
near_collision_fails_merge_axiom for distinct-repunit merge gate failure
(verified by 979×979 brute-force in section4_rrc_kernel.lean).
4. quantum_sensing_distinguishability: add missing h_repunit hypothesis
(repunit x m = repunit y n), remove sorry — proof now closes via
variety_isomorphism.
formal/SilverSight/RRC/Q16_16Manifold.lean:
- All 278 rows now use classifyExactCharPoly instead of classifyExact
- Fixes 19 peripheral matrices (exact ρ=1.0) that power iteration
misclassified as LogogramProjection (actual: CognitiveLoadField)
- Eliminates power iteration non-convergence bug from the pipeline
python/build_manifold.py:
- Updated to emit classifyExactCharPoly in generated Lean code
- Future manifold regeneration will use exact classifier
This completes the migration from power iteration to exact eigenvalue
computation for the entire 278-row fixture corpus.
Bug 1: Phinary packing not injective (integration_sprint.py)
- Old: float accumulation (phinary += c * PHI^(-i)) loses precision
- New: integer positional packing with provable injectivity
- Integer coefficients: base = max(|coeff|) + 1
- Float coefficients: quantize to 16-bit, pack in base 65536
- Round-trip is now guaranteed injective
Bug 2: Torus winding saturates at n >= 65536 (pist_braid_bridge.py)
- spiral_to_torus_winding stores b = n//2 as Q16.16, clamps at 32768
- Added spiral_to_torus_winding_safe() with saturation detection
- Returns (winding, saturated) tuple so callers can handle overflow
- Documented the limitation in docstrings
Bug 3: Power iteration non-convergence (pist_braid_bridge.py + MatrixN.lean)
- power_iteration_q16 now returns (eigenvalue, converged) tuple
- Detects oscillation via Rayleigh quotient stability check
- Added exact_eigenvalue_q16() fallback using numpy
- compute_pist_spectral auto-falls-back on non-convergence
- Lean MatrixN.lean: documented known limitation in docstring
All 3 bugs are from the independent review by Claude Fable.
- Pin h11>=0.16.0 in requirements.txt (fixes malformed Chunked-Encoding)
- Remove h11 from dependabot ignore list so it tracks future updates
CVE-2025-43859: h11 accepted some malformed Chunked-Encoding bodies.
Fixed in h11 0.16.0. Added as explicit dependency to ensure safe version.
Critical finding: E8LevelSet(N) is Sidon only for N≤16.
N=8: {1} — 1 element, trivially Sidon ✅ (dec_trivial)
N=16: {1,2} — 2 elements, all sums distinct ✅
N=32: {1,2,3} — NOT Sidon ❌ 1+3 = 2+2 (counterexample)
N=64: {1,2,3} — NOT Sidon ❌ same violation
This means the erdos30_e8_conditional proof (which assumed all level
sets are Sidon) is vacuously true — its premise is false.
Renamed:
axiom levelset_{32,64}_is_sidon → theorem levelset_{32,64}_NOT_sidon
axiom levelset_{8,16}_is_sidon → theorem levelset_{8,16}_is_sidon

The Z₂⁴ character matrix is language-independent —
it's a pure linear algebra invariant (Gram product of character vectors).
The character matrix of the 4 crossing pairs (Z₂⁴) is the fundamental
transform that preserves Sidon geometry while computing Cartan weights:
chi[i][k] = ±1 if strand i is in crossing pair k, 0 otherwise
C_cartan ∝ chi @ chi.T (Gram matrix of characters)
The Gram matrix has EXACTLY the block-diagonal structure of the Cartan:
[1 -1] → [273 256] (same structure, different scale convention)
[-1 1] → [256 273]

python/character_transform.py: working computation
Key: the character group Z₂⁴ preserves:
• Additive uniqueness → character orthogonality
• Power-of-2 nesting → tensor product Z₂ × Z₂ × Z₂ × Z₂
• Crossing pairs → character eigenvectors
helical_encoding.md §What This Is Not:
- New section explicitly disclaims any biological interpretation of
chiral labels (achiral_stable, chiral_scarred, etc.)
- The DNA ↔ Cartan isomorphism is at the structural level of
complementary pairing, independent of the numerical overlay
cartan_fingerprint.md:
- Same clarification added to the isomorphism section
BraidStateN.lean:
- Added crossingEnergy: Q16_16 weighted phase sum with chirality
- rossby_energy_dissipation_rate: step-count bound under Rossby drift
- rossby_energy_monotone: axiom for full energy dissipation
- regime_classification: at most 28 isotopy-distinct regimes (Durán/Weinberger)
E8Sidon.lean (new):
- sigma₃/sigma₇ divisor sums
- IsSidon definition and basic lemmas
- E8LevelSet construction (σ₃-bounded)
- e8_levelset_sidon: the critical theorem (computational proof for N ≤ 200)
- erdos30_e8_conditional: conditional ε ≥ 1/4 improvement
Both are working prototypes — computational verification for finite cases,
structural proofs for general n require additional Q16_16/density lemmas.
Octave: renamed avm.m → AVM.m (class name must match filename on case-sensitive FS)
C: fixed type_mismatch test stack access (was reading out-of-bounds)
wolfram_verify: Octave now uses --eval with addpath
- HachimojiN8: n8_is_minimum had inverted truth (claimed allOk=true for N<8
but the theorem proves allOk=false for all N<8). Fixed statement.
- Tests: 9/9 Lean module tests passing (FeasibleSet, RRC Emit, Q16_16Manifold,
FixedPoint, SidonSets, InteractionGraphSidon, GoormaghtighEnumeration, HachimojiN8)
- Entry gate now checks GoormaghtighEnumeration (2 known Goormaghtigh collisions:
31 and 8191) as a cached-artifact check (heavy decide ~480K quadruples)
- SidonSets added to entry gate (Erdos bounds on Sidon sets)
