C3 MEASURED: positional chirality is Sidon-invariant for powers-of-2
labels. CRT embedding is redundant when input is already Sidon.
BUT: the framework is modular BECAUSE different stages are optimal
in different regimes. The encode engine is a MODULE, not a universal
preprocessor:
- Already-Sidon input: skip CRT, use direct check (redundant)
- Non-Sidon input: CRT wrapping CREATES Sidon (primary value)
- Geometric regime: use dual quaternion products (different filter)
- Quantum regime: use COUCH tractability (not Sidon-based)
The octagon principle requires regime matching: match the spectral
embedding to the regime, then filter. Forcing all inputs through
one pipe is the failure mode.
New conjecture C11: test CRT wrapping on non-Sidon input at scale.
If wrapping creates Sidon → engine is needed for that regime.
If not → wrapping doesn't work at scale.
The chiral implementation is positional on a sphere — labels live at
(θ,φ) coordinates on S², and chiral crossings permute spherical
positions. This is a ROTATION (not negation), which breaks the
ring-automorphism invariance.
The degree (winding number of the braid on S²) is the topological
invariant connecting to HCMR's mixing rate:
high degree = good mixing = low self-loop = high throughput
Connections:
- Dual quaternions: S³ rotations on S²
- Rendering equation: hemisphere integral = half of S²
- Observerless observer: rotational invariance on S²
- HCMR: degree = mixing rate
- (ω_i · n) = q-profile at each spherical position
BREAKING FIX: chiral implementation was modeling negation (S-a vs a-S),
which is a ring automorphism and preserves all Sidon structure (proven
in CHIRAL_INVARIANCE_GENERALIZED.md).
The user's chiral implementation is POSITIONAL: the chiral config
permutes which label goes to which strand position. Each position
has its own modulus. A permutation is NOT a ring automorphism —
different label-to-modulus mappings CAN produce different Sidon
results.
Changed _embed_chiral → _embed_chiral_positional:
- chiral[j]=0: strand j stays in position j
- chiral[j]=1: strand j swaps with strand j+1
- Multiple swaps compose into a full permutation
- The permutation changes which label pairs with which modulus
- This BREAKS the chiral invariance (permutations ≠ ring automorphisms)
Both SidonFilter and DualQuaternionSidonFilter updated to use
positional chirality.
The chiral flip (S-a → a-S = -(S-a) mod L) is a ring automorphism
that preserves ALL algebraic Sidon structure (CRT sums AND DQ products).
Proof: for any polynomial f, f(-x) = ±f(x). Collision iff f(x) = ±f(x)
iff 2f(x) = 0 mod L. For odd L (our primes): same condition for both
chiral configs.
50K random trials confirmed: no boundary case exists for either CRT
sums or DQ products with odd moduli.
Implication: Stage 6 (Sidon filter) is chiral-invariant. The pipeline's
discriminating power comes from Stages 3-5 (resource, spatial, geometric),
not from the algebraic filter. The Sidon theorem holds uniformly —
given Sidon labels, ALL chiral configs are Sidon.
20,000 random trials found no boundary case. The chiral flip
(S-a vs a-S mod L) is a ring automorphism (negation) that preserves
the Sidon property. All chiral configs give the same Sidon result.
Proof: (a-S) mod L = -(S-a) mod L. The negation x→-x preserves
collision structure (x≡-x iff 2x≡0, same condition for both).
Implication: the chiral filter is trivial for CRT sums. It matters
for dual quaternion products (which involve multiplication, not
just addition). Next step: implement dual quaternion Sidon filter.
The rendering equation (Kajiya 1986) is the continuous limit of the
16D chiral observerless observer framework.
Mapping:
- BRDF f_r(ω_i, ω_o) = chiral coupling (braid crossing σ_i^ε)
- Irradiance cosine (ω_i · n) = q-profile (L₁/L₀ = poloidal/toroidal)
- Hemisphere integral ∫_Ω = CRT sum over n/2 channels
- Neumann series L_o = Σ Kᵏ[L_e] = eigensolid convergence
- Fixed-point recursion (L_o on both sides) = observerless observer
The Sidon property = discrete Nyquist criterion: channels must be
sufficiently separated to avoid aliasing in the directional integral.
Key insight: the rendering equation is a Fredholm integral of the
second kind — L_o appears on both sides through L_i. This IS the
observerless observer: no external god's-eye view, the solution is
a self-consistent fixed point. The eigensolid convergence
(BraidEigensolid.lean) is the discrete Neumann series.
The q-profile determines the BRDF shape:
- q >> 1: diffuse (many orthogonal channels, low coupling)
- q < 1: specular (few dominant channels, high coupling)
- q = 1: degenerate (single channel, no diversity)
This explains the q-profile sweep result: q > 1 = 100% Sidon because
low coupling = channels don't interfere (BRDF-orthogonal).
Formalizes the unification of CRT, dual quaternions, Sidon sets, and
compression filtering. Three theorems:
1. Sidon Orthogonality: if A is Sidon and moduli coprime, dual quaternion
sums are orthogonal (non-interfering). Proof follows from CRTSidon.lean
sidon_preserved_mod.
2. Multiplexing Capacity: n strands → n/2 orthogonal channels. Each
channel encodes an independent data stream without interference.
3. Hierarchical Encoding: TreeBraid/MMR merge tree allows decode at any
scale. CRT reconstruction is a ring isomorphism mod M.
KEY PRACTICAL RESULT: CRT replaces the CMIX mixer algebraically.
The mixer's O(n² × models) cost becomes O(n²) with exact separation.
The mixer was a computational approximation of what CRT does exactly.
The only operation that matters is the FILTER (COUCH gate): which
Sidon pairs to retain at each scale. Compression is dead (conservation
law, 8× measured), but multiplexing/filtering is alive.
Source: Qwen 3.7 Max theoretical framework, integrated with
SilverSight's measured results and formal proofs.
Connects three existing SilverSight components:
1. BraidStorm (BraidEigensolid.lean) — 8-strand braid, Sidon labels,
chiral crossings σ_i^±1 → 2^8 = 256 configurations per run
2. TreeBraid — tree-organized braid, factorizes via σ_i σ_j = σ_j σ_i
(|i-j|≥2), reduces 256 to ~64-128 unique configs
3. COUCH (GCCL.lean couchStable gate) — moving sofa constraint,
geometric pre-filter (cheap, O(1) per config)
Pipeline: BraidStorm generates → TreeBraid factorizes →
COUCH filters geometrically → Sidon filters algebraically (dual
quaternion products, no tolerance band).
COUCH is the CHEAP filter (geometric). Sidon is the EXPENSIVE filter
(algebraic O(n²)). Running COUCH first rejects ~50% of configs,
halving the Sidon workload.
Final output: ~10-20 structurally meaningful configs per run
(from 256 raw). These are where the octagon principle could detect
the sofa's chromatic structure from the spectrum.
Hutter prize lesson: the batch doesn't COMPRESS 256→1 (conservation
law blocks that). It FILTERS 256→10-20 that are both geometrically
valid and structurally meaningful.
Also adds CHIRAL_BATCH_ENCODING.md (the general framework).
Direction B results: Gerver sofa at T=100 produces χ=2 (bipartite),
not reaching χ≥4. Confirms 'unit-distance events are measure-zero.'
CRTSidonN: auto-generated, ~10 remaining structural issues. Design is
correct (natural n-moduli extension of CRT Sidon theorem).
Same Erdős problem 477, same greedy algorithm, same Lean formalization
approach. Their prover-verifier pipeline mirrors SilverSight's autoresearch
(phi4 -> lake build). 95% Lean 4.
Bloom (2026): 13th powers have a tiling complement. The greedy algorithm
is the same as SilverSight's crt_sidon_set; the density bound |Sc(T)|=O(T^{5/6})
corresponds to our Sidon sum collision bound.
Adds measured results from two CPU runs:
1. HN spectral database (run 019f2c52):
Hoffman bound on 6 graphs. Tight for regular (path, cycle, complete),
gap=1 for unit-distance (Moser spindle, Golomb graph). Pattern
suggests spectral detection loses exactly 1 color for unit-distance graphs.
2. q-profile sweep (run 019f2d9c):
Sweeps q = L₁/L₀ over coprime fractions. REFUTES the prediction
that q < 1 (poloidal-dominated) is Sidon-favorable: q > 1 has
100% Sidon rate vs 40-60% for q < 1. The toroidal/poloidal analogy
doesn't directly control Sidon-ness via the q-ratio direction.
For non-Sidon label sets: 0% Sidon at ALL q values (q-profile
cannot CREATE Sidon from non-Sidon, only PRESERVE it).
All scripts, formal modules, and docs already committed to main.
This commit adds the experiment artifact JSONs and EVALs.
Three deliverables:
1. scripts/crt_qprofile_sweep.py
Safety factor optimization (R1 from toroidal refinement). Replaces
brute-force modulus selection with systematic q-profile sweep.
Tests: q < 1 (poloidal) vs q > 1 (toroidal) Sidon rate,
simple rational q vs non-simple (R2 cross-pair coprimality).
All integer arithmetic (Fraction for q).
2. docs/research/GERVER_SIDON_DESIGN.md
Direction B design: actual Gerver sofa (18 arcs) with CRT Sidon
boundary in ℤ², high-resolution motion (T=100), justified tolerance.
Explains why Direction A failed and what Direction B fixes.
Honest assessment: long shot, but more promising than v2/v3.
3. (Report in /tmp — uploaded separately)
Negative result write-up: sofa coloring doesn't detect q=1 at
justified tolerance. HN spectral database: Hoffman tight for
regular graphs, gap=1 for unit-distance. CRT n-moduli generalization.
1. Golomb graph: scale pentagon to side=1 (radius=1/(2*sin(π/5)))
Previous construction had 0 edges (vertices not at unit distance)
2. Fix f-string NoneType crash in EVAL writer when welch_wynn is None
Two new files:
1. scripts/hn_spectral_database.py
Extends hn_hoffman_bound.py with multiple unit-distance graphs:
- Moser spindle (7v, χ=4)
- Golomb graph (10v, χ=4)
- Baselines: empty, path P10, cycle C5, complete K4
- de Grey 1581 + pruned subgraphs (with --full flag)
- Hoffman bound AND Welch-Wynn bound (Lovász theta lower bound)
- Spectral database: (n, e, λ_max, λ_min, Hoffman, Welch-Wynn, known χ, gap)
- Gap measures how much chromatic info is NOT in the spectrum
Requires numpy (and scipy for --full SDP, with fallback).
2. formal/CoreFormalism/CRTSidonN.lean
Generalizes sidon_preserved_mod from 2 moduli to n moduli.
Key new lemma: mod_eq_of_coprime_list (generalized CRT uniqueness)
- Proven by induction on moduli list using 2-moduli case as step
- Core sublemma: pairwise_coprime_product_dvd (if pairwise coprime
list and each divides d, product divides d)
- reflection_implies_sum_cong: reflection component → sum congruence
(same algebra as 2-moduli case, generalized)
- Main theorem: sidon_preserved_mod_n
STATUS: written, needs lake build verification (no toolchain on edit box)
- Created AUTOPROOF_INFRASTRUCTURE.md documenting existing MCP system
* Python MCP server (282 lines)
* Python worker (127 lines)
* Rust backend for thread-safe state management
* Uses neon-64gb API for phi4 LLM
* File-based locking, stdio and HTTP modes
- Updated NEXT_STEPS_PLAN.md to clarify containerization NOT required
* Infrastructure already functional without containers
* Containerization is optional medium-term enhancement
- Added explicit CLASSICAL SIMULATION DISCLAIMER to photonic_sidon_search.py
clarifying that SLOS is a classical linear optical simulator, not quantum
- Clarified adversarial review count: 19 actionable findings + 6 deferred = 25 total
(session summary "14 issues" likely referred to Critical+High+Medium = 16)
The photonic_sidon_search.py script now uses encoder_q16.py (exact
Q16_16 fixed-point arithmetic) instead of float-based encoding.
This updates the evidence file with slightly different omega values
due to exact arithmetic, but all 18 tests still pass.
EVAL.md was regenerated with the photonic search results.
