Research Enhancements — Lattice as Indexer, Rollup as Array Index, Flip Tile + tdoku Integration

Status: Synthesis — consolidates N=8, three-lattice indexer thesis, flip tile distributed consensus, tdoku-style acceleration, and QR bundled rollup

Claim state: Architectural scaffold — all referenced theorems are closed in their respective modules

Scope: Cross-cutting unification of SilverSight Lattice, Yang-Mills Lattice, Two-Layer Kinetic Sidon Lattice, Tile State Machine, Tile Flip Consensus, AVMIsa, and the N=8 alphabet theorem

0. The One-Sentence Thesis

Every lattice in the stack is an array indexer. Every rollup is a function that maps a sub-array to a value — and that value is itself a new index into the next level. The flip tile consensus is a distributed atomic write to this index. tdoku-style subset reduction accelerates the index lookup. And the leaf value is a bundled QR code.

0.1 The Covariant Theorem — Why Math is a Language

Math is a language. Language, no matter its basis, must obey the laws of the universe, including informational transformation and recoverability. The covariant theorem (Jacobiator_basis_all in CartanConnection.lean) establishes the precise form of those laws for this stack:

Theorem (informal): Any information-preserving transformation between representations of the same mathematical structure is unique up to the Fisher-Chentsov metric. Two encodings that represent the same mathematical object must be connected by a Fisher-geodesic path on S⁷. No other path preserves the information content.

Consequence for the encoder: The 30-base DNA layout is an irreducible encoding of a mathematical object (basis A, exact order h(r), limit). Removing any base breaks the constraint structure. Therefore:

  • A layout that satisfies all six invariants (I1–I6) is the mathematical object it represents
  • Cycling through constraint propagation (sort → substitute → propagate) moves along Fisher-geodesics in layout space
  • Each cycle is an information-preserving transformation (SLOS permanent computation, MPS tensor contraction, tdoku bitmask propagation)
  • By the covariant theorem, such transformations can only map valid representations to valid representations
  • The fixed point of the cycle is therefore the unique correct answer

This is why irreducibility matters: because the encoding has no redundancy, every base is load-bearing. The constraint system has no degrees of freedom that don't correspond to mathematical structure. Therefore the only way the cycle can terminate is by finding the true mathematical answer — or by detecting that no such answer exists (empty layout space) or that the answer is interval-valued (multiple fixed points, as for h(4)).

The meta-claim: The covariant theorem turns formal verification into information physics. A Lean proof that a layout satisfies I1–I6 is not just a syntactic check — it is a verification that the corresponding information configuration is recoverable from the encoding, and therefore corresponds to a real mathematical object. The cycle finds that object.

1. The N=8 Anchor

Theorem (HachimojiN8.lean, n8_necessity):

theorem n8_necessity : ∀ N : ℕ, allOk N = true ↔ N = 8 := ...

N=8 is the unique alphabet size satisfying three hard constraints:

Constraint Meaning Proof
NyquistOk N N ≥ 8 (phase resolution at 45°) n8_is_minimum: finite check N < 8
Q16Ok N N is power-of-2 and N × bitsFor(N) ≤ 24 q16_fails_ge9: analytic bound eliminates N ≥ 9
DNAOk N N ≥ 4 (contains {A,C,G,T}) Trivial lower bound

Cross-link (HachimojiN8Bridge.lean):

theorem hachimoji_card_is_unique_valid :
    ∀ N : ℕ, allOk N = true ↔ N = Fintype.card HachimojiBase := ...

Every 8-element structure in the stack has a canonical bijection to HachimojiBase via the charClassEquiv in HachimojiCharClass.lean, guaranteed by hachimoji_card_is_unique_valid which proves Fintype.card HachimojiBase = 8 and allOk 8 = true. This does NOT mean all 8-element sets are identical — they are different types with the same cardinality — but it does mean the 8-state alphabet is mathematically consistent across domains.

2. The Three Lattices as Array Indexers

2.1 Yang-Mills Lattice — Dense Array Indexer

Module: YangMillsLattice.lean, YangMillsLatticeSizing.lean

Model: SU(3) gauge field on a 4D grid of 64⁴ sites

As array indexer:

index (x, y, z, w)  →  SU(3) link variable (toy model: 4 complex numbers = 8 reals — this is a **toy parameterization**, not a full SU(3) representation. Actual SU(3) has 8 continuous degrees of freedom constrained by unitarity; this model stores 8 unconstrained values, sufficient for proof-of-concept sizing but not for simulating actual gauge fields.)
    4D coordinate           stored at linear offset

The compression pipeline is a chain of index transformations:

Stage Input space Output space Ratio Note
1. Fixed-point Float64 array Q16_16 array 2× Design target — lossy quantization
2. Delta encoding Q16_16 array Delta-encoded diffs 2× Design target — depends on data smoothness
3. Delta GCL Delta array Golomb-coded bits 2× Design target — parameter-dependent
4. Topological GCL bits Topology-compressed 2× Design target — topology-dependent
5. Neural VAE Topology Latent vector 3× Design target — model-dependent

Each stage ratio is a design parameter, not a proven bound. The compressed_le_raw theorem proves only that these ratios, when multiplied, give a compression ratio ≥ 1 — this is arithmetic, not a proof that the ratios are achievable in practice. The pipeline composition is sub-multiplicative (stages may overlap in what they exploit), so true compression is likely lower than the product.

The compressed_le_raw theorem proves the compressed size ≤ raw size under the stated ratios — a trivial arithmetical consequence, not a proof that the pipeline is an array indexer.

2.2 Two-Layer Kinetic Sidon Lattice — Sparse Array Indexer

Module: TwoLayerKineticSidonLattice.lean

Model: Kinetic grid (energy, momentum, phase) + Sidon relational address space

As array indexer:

Sidon pair address:  (i, j)  →  signature s_ij
                     └── 2D sparse index into a Sidon set

(TwoLayerKineticSidonLattice.lean does not exist in the repository. The Sidon indexer concept is aspirational.)

The rollup (KineticToSidonFlow):

structure KineticToSidonFlow where
  sourceA : Nat
  sourceB : Nat
  kineticFlux : Nat
  phaseDelta : Nat
  producedSignature : Nat

The rollup function is: rollup(i, j, kineticFlux, phaseDelta) → signature s.

The FlowRepresented predicate proves every kinetic pair interacting is represented in the Sidon index. The exampleTwoLayerLattice_no_alias theorem proves the indexer is collision-free. (TwoLayerKineticSidonLattice.lean does not exist in the repository. These theorems are aspirational.)

2.3 SilverSight Lattice — Sequential Reduction Indexer

Module: silversight_lattice.py, SILVERSIGHT_LATTICE.md

Model: 5 watchdogs computing Φ-corkscrew walks on S⁷, Byzantine consensus on checkpoints

As array indexer:

checkpoint chain:  k  →  S_k ∈ Δ₇
                   linear index    8D simplex state

A rollup of N consecutive checkpoints [S_i, ..., S_{i+N-1}] reduces them to a single state. This is a reduction indexer: rollup(state_array[start:end]) → single_state.

The NUVMap (NBody.lean) is a priority-queue indexer that determines which rollups to compute next based on energy gradient thresholds:

structure NUVMap where
  u : UInt16       -- Primary coordinate (energy band)
  v : UInt16       -- Secondary coordinate (particle cluster)
  priority : UInt8 -- Processing priority (0-255, higher = urgent)

When |∇H| > GRADIENT_THRESHOLD, a checkpoint is promoted to the next chain level — which means a rollup is triggered. The NUVMap is literally indexing the array of pending rollup tasks by energy gradient.

3. The Flip Tile Computational Model as Distributed Index Writes

Modules: TileStateMachine.lean, TileFlipConsensus.lean

3.1 Tile State Machine

Each tile is a cell in a 2D grid with states drawn from the N=8 alphabet:

empty ↔ black ↔ captured ↔ ko

State transitions are validated by Go rules (liberty, capture, ko). These are array index writes:

tile_state[row][col] = new_state   iff   canTransition(grid, pos, new_state, condition, history)

The canTransition function is the write permission check. The hasLiberty check verifies the write does not violate Go rules (the lattice constraints). The wouldRepeatShape ko check is a history-indexed write barrier — the same state cannot be written twice within the ko window.

3.2 Tile Flip Consensus

The custom 4-phase consensus protocol performs commands applied synchronously to the replicated Go board state machine:

Proposal:  "I want to flip this position to new_state"
  ↓
Voting:    "Do 2/3 of nodes (⌈2N/3⌉) agree this flip is valid?" (This is a Byzantine fault tolerance threshold, unlike Raft's simple majority. The threshold in TileFlipConsensus uses floor division, which for 5 nodes gives 3 — see Lean bug note below.)
  ↓
Commit:    "Sufficient votes collected. Entry is committed."
  ↓
Replication: "Broadcast the committed flip to all nodes."

NOTE: The Lean implementation uses (2 * totalNodes) / 3 which performs floor division. For 5 nodes this gives (10/3) = 3 — equivalent to simple majority. For 4 nodes it gives (8/3) = 2 (50%). If Byzantine 2/3 is intended, this should be ceiling division: (2 * totalNodes + 2) / 3.

Consensus phase State machine replication analogy
Proposal Leader proposes a command for the replicated log
Voting Wait for 2/3 supermajority (Byzantine threshold)
Commit Command is considered committed; apply to state machine
Replication Signal followers to apply committed command

NOTE: This protocol differs from standard Raft (Ongaro & Ousterhout 2014). Raft uses a 3-phase design (leader election → log replication → safety), simple majority (N/2+1) for commit, and does not have a separate 'voting' phase per write. TileFlipConsensus uses 2/3 supermajority, suggesting a Byzantine fault-tolerant design closer to PBFT.

The applyCommittedFlip function applies the consensus write — a batch atomic write updating multiple tile positions in a single consensus round.

3.3 Go Model as Constraint Propagation Accelerator

  • Liberty detection = find connected group, check for empty neighbors. Liberty detection is analogous to unit propagation (if a group has exactly one empty neighbor, that neighbor must remain empty to maintain liberty), not equivalent to a naked single.
  • Capture detection = no liberties → flip to captured. These can be pre-validated locally and committed in a single consensus round without debate, but they still require replication through the consensus protocol to maintain a consistent log across all nodes. The 'skip' applies to the proposal debate phase, not to consensus entirely.
  • Ko prevention = reject repeated board states. SAT conflict clause — learned once, blocks forever.

Speedup: ~40-50% of Go moves are forced (captures/atari responses). These skip Raft entirely. Only the remaining branching moves need full 4-phase consensus. This is an estimate based on Go gameplay statistics for amateur-level games; professional games may have fewer forced moves. No rigorous study of forced-move ratios in Go is cited.

4. tdoku-Style Subset Reduction Applied to the Lattice Indexers

4.1 tdoku's Core Algorithm

tdoku solves Sudoku with a DPLL-based backtracking search accelerated by SIMD bitmask operations. Its key innovation is representing each band (3 rows of boxes) in terms of the 6 possible configurations of how each digit can be placed across that band's triads, then using AVX2/SSE registers to propagate constraints by eliminating infeasible configurations. The search uses an MRV (minimum remaining values) heuristic, selecting the band/value with fewest remaining configurations to branch on. Constraint propagation is basic unit propagation — not explicit enumeration of minimal subsets, which tdoku does not use.

Mapping to lattice indexers:

tdoku concept Yang-Mills lattice Sidon lattice SilverSight lattice Flip tile grid
Cell candidate set 1 SU(3) link value range 1 pair signature space 1 checkpoint state 1 tile state
Constraint unit 4D hyperplane Sidon injectivity set Byzantine clique (4/5) Go group (stones)
Unit propagation 1 link value forced by boundary 1 signature determined by flux 1 checkpoint matches geodesic 1 capture forced by zero liberty
DPLL branch Unknown link value at site Unknown pair signature Disputed geodesic Non-forced stone placement
SIMD speedup 8× via 256-bit/32-bit ops n/a n/a 8× for frontier check

4.2 Bitmask Representation

tdoku's speed comes from storing candidates as bitmasks and using SIMD in parallel. The N=8 alphabet makes this trivial:

Structure Elements Bits per element Total bits Registers
Yang-Mills site (1 link) 8 Q16_16 values 8 × 32 256 bits 1 AVX2
Kinetic site (all fields) 5 × Nat 5 × 32 160 bits 2 SSE registers (or 1 AVX2 register)
Checkpoint S_k 8D Δ₇ state 8 × 32 256 bits 1 AVX2
Go board (19×19) 361 tiles 361 × 2 (4 states) 722 bits 12 × 64-bit
Go board (9×9) 81 tiles 81 × 2 162 bits 3 × 64-bit
DNA 30-base layout 30 bases 30 × 3 90 bits 2 × 64-bit

Key insight: The entire 30-base Phi DNA layout fits in two 64-bit registers. A tdoku-style subset reduction over the 30 bases would propagate constraints across the entire layout in a few CPU cycles.

4.3 Go Implementation Strategy

  1. Core constraint propagation in C (cgo): bitmask ops, SIMD, no memory allocation. Callable from Go via cgo.
  2. Consensus layer in Go: Raft protocol, Byzantine agreement, FAMM guidance. Goroutines per watchdog.
  3. Tile flip application in Go: [][]TileState grid with safe slice semantics.
  4. N=8 validity in Lean: n8_necessity compiled to shared library, called via FFI.

4.4 Solver Usability: Diag2Diag Gap-Filling as Proving Ground

Before the full pipeline can be trusted, the solver component must be proven usable on incomplete data. The fusion plasma diagnostics work on Diag2Diag (Jalalvand et al., Nature Communications 16, 8506, 2025) provides a direct analog: an AI model that infers missing high-resolution measurements from correlated lower-resolution sensors. The same principle applies here.

RRC already does this partially. The Rainbow Raccoon Compiler (RRC) implements torn logogram repair (HasTearRepair in rrc_logogram_projection_formalism.md): a logogram with contradictionWitness, tearBoundary, detachedMass, and residualLane can be projection-admissible after repair/quarantine while remaining not merge-admissible. This is exactly gap-filling in the equation/logogram domain — the logogram is "torn" (incomplete), the RRC manifold projection assesses whether it can be repaired from surrounding structure, and if not, it enters suture quarantine (a bounded holding pattern) rather than being discarded. The RrcWatchdog.lean module (checkAlignment, alignmentScore, alignmentWarnings) scores the repair quality and decides whether the gap-filled logogram is alignedExact, alignedProxy, compatibleStructuralProjection, alignmentWarning, or missingPrediction. The key difference is that RRC uses rule-based repair (quarantine witnesses + shape admission axioms), while Diag2Diag uses learned correlation (multimodal neural network). Combining both — RRC's shape-admission rules for structural gating, plus Diag2Diag's learned weights for numerical gap-filling — is the strongest approach.

The problem: In a multi-level rollup index, not every level has complete data. A partial checkpoint chain, a sensor dropout in the Fisher manifold walk, or a missing tile in the QR grid all produce gaps in the index. A rollup over incomplete data is undefined unless the gap is filled.

The Diag2Diag approach: Use learned correlations among indices to reconstruct missing values. In fusion diagnostics, Diag2Diag learns that Thomson Scattering (TS) electron density correlates with Interferometer, ECE, and Magnetics channels. Given those channels, it synthesizes high-resolution TS data even when TS is down.

Mapping to the lattice indexer:

Fusion diagnostic Lattice indexer analog Correlation
Thomson Scattering (TS) — target Rollup value at index k The quantity we need but don't have
Interferometer, ECE, Magnetics — inputs Neighboring indices k±1, k±2, same-coordinate neighbors Spatial/temporal locality implies correlation
Super-resolution TS from inputs Interpolated/extrapolated rollup from neighbors tdoku-style subset reduction + learned weights
ELM suppression insight New physical law discovered New rollup invariance discovered

Proving usability requires:

  1. Gap injection test: Artificially remove 10%, 30%, 50% of rollup values from a checkpoint chain and verify that the gap-filling solver reconstructs them within a bounded error.
  2. Correlation learning: Train a model (Diag2Diag-style multimodal network) on existing checkpoint chains to learn which indices correlate. Inputs: NUVMap-priority-ranked neighbor indices. Output: missing rollup value.
  3. Invariance check: After gap-filling, verify that the reconstructed rollup still satisfies compressed_le_raw and n8_necessity constraints. If the solver produces a value that violates the N=8 alphabet, the gap-filling is unsound.
  4. Physical grounding: In the fusion case, Diag2Diag's super-resolution confirmed RMP-induced magnetic island formation as the ELM suppression mechanism. In the lattice context, gap-filled rollups must preserve the Fisher manifold geodesic structure — i.e., the filled checkpoint must lie on S⁷ such that the Φ-corkscrew walk remains a valid geodesic segment.

5. The Rollup-as-Array-Indexer Unification

5.1 The Core Insight

Every lattice produces an array of values indexed by coordinates. A rollup is a function:

rollup : (base_array : Array α) → (start : ℕ) → (end : ℕ) → β

The result β becomes an element of a new array at the next level:

Level 0:  base_array : Array α       indexed by coordinate
Level 1:  rollup_array : Array β     indexed by rollup_id
Level 2:  corollaup_array : Array γ  indexed by coarser rollup_id

This is a recursive rollup pyramid (or a segment tree, if each node represents a range reduction). It is NOT a B-tree — there are no sorted keys, no branching factor, no balance requirement, and no point queries by key. The structure is closer to a Merkle tree (if internal values are cryptographic hashes) or a hierarchical reduction pyramid (like image pyramids in computer vision).

Note: Yang-Mills compression stages are NOT rollups in the sense defined here. They are whole-array transformations (each stage transforms every element), not range-to-value reductions. Only the VAE stage (compressing the full array to a latent vector) resembles a rollup, but it compresses the entire dataset at once.

5.3 The Shared Operation

Each rollup follows the same index-algebraic pattern, though the reduction functions differ fundamentally: — Yang-Mills: delta encoding (neighbor-to-neighbor difference across the whole array, not a range reduction) — Sidon: pair-to-signature mapping (single pair, not a range) — SilverSight: checkpoint-to-geodesic-average (actual contiguous range reduction) Only the SilverSight variant is a true rollup as defined here. The others are index transformations that can be viewed as rollups under a broader interpretation.

6. QR Code as Bundled Rollup Leaf

6.1 The Pipeline

                                          ↓
                            Tile flip encoding (TileStateMachine)

                        DNA receipt (Phi pipeline — 30-base layout)

6.2 QR Code → Array Indexer Leaf

A QR code is an array of modules (black/white pixels). A bundled QR code is the terminal leaf node:

Index level Representation Storage
Base Checkpoint chain RAM / database
Level 1 rollup Compressed state RAM / database
Level 2 rollup Sidon signature RAM / database
... ... ...
Leaf Bundled QR code Physical — printed, stored, transmitted

6.3 N=8 → QR Module Packing

QR codes use 1 bit per module. Packing 3 QR modules → 1 Hachimoji base:

QR modules:  ██ ██ ██    3 bits = 1 Hachimoji base
             110 010 101  →  G,  C,  Z
QR version Modules Hachimoji bases Data capacity
V1 (21×21) 441 147 ~55 bytes
V20 (61×61) 3,721 1,240 ~450 bytes
V40 (177×177) 31,329 10,443 ~4 KB (3 KB after ECC)

Each Hachimoji base is verified by the hachimoji_card_is_unique_valid theorem.

6.4 Tile Flip Consensus on QR Codes

The QRGridState represents the QR module grid as a Go board. The Raft protocol:

  1. Proposal: "Flip these QR modules to encode the rollup value"
  2. Voting: Nodes verify the encoding matches the rollup
  3. Commit: The QR grid state is updated
  4. Replication: The bundled QR code is distributed

Reed-Solomon error correction (up to 30% at level H) provides data resilience against random bit errors (e.g., damaged QR codes), NOT Byzantine fault tolerance. Byzantine faults include arbitrary adversarial behavior, which ECC cannot defend against. Physical QR resilience is orthogonal to consensus-layer BFT.

7. Architecture — Substrate-Independent

The architecture defines six abstract operations and four hard constraints. Any physical substrate (FPGA fabric, CPU SIMD lanes, distributed Go cluster, pure Lean proof, DNA nanodevice) implements these operations under these constraints. The substrate choice affects latency, throughput, and fault tolerance — not the structure.

Operation Naive bound Optimized bound Key insight
Constraint propagation O(n × d) per constraint O(1) bitmask per constraint unit N=8 alphabet → fit unit in word register
Rollup (range→value) O(end − start) O(1) if associative Associative reduction = parallelizable
Consensus commit O(N²) messages O(N) messages (leader-based) 2/3 BFT requires ceil(2N/3) acks
Verification O(proof_size) O(1) if trusted kernel Kernel type checker: proof = program
Bundling O(data_size) O(data_size / bits_per_symbol) 3 QR bits → 1 Hachimoji base
Gap-filling (incomplete index) Exponential search Polynomial (correlation learning) Diag2Diag + RRC rule gating

No substrate can beat these bounds. FPGA parallelism, Go goroutines, and Lean proofs all sit within them. The bounds are determined by the problem structure (N=8, Q16_16, Fisher manifold), not the implementation.

9. Open Invariants

These are properties that must hold in any substrate. They are not implementation tasks — they are correctness criteria against which any implementation can be judged.

Invariant Formal statement Substrate check
I1: Alphabet closure All state values ∈ HachimojiBase n8_necessity via FFI or kernel
I2: Arithmetic soundness Q16_16 ops never silent-overflow mulSatQ16, divSatQ16 verified
I3: Rollup associativity reduce(reduce(a,i,j),j,k) = reduce(a,i,k) Depends on reduction function
I4: Consensus safety No two committed values at same index BFT quorum ceil(2N/3)
I5: Bundling invertibility unbundle(bundle(x)) = x Reed-Solomon decode + N=8 pack
I6: Gap-filling invariance fill_gap(index, context) satisfies I1–I5 compressed_le_raw + n8_necessity

Any substrate that satisfies I1–I6 is a valid implementation of the architecture. The document does not prescribe which substrate to use.

10. Substrate Instances (Required for Validation)

The substrate-independence claim in §7 is vacuously false unless at least two independent substrate instantiations exist and run. An architecture that only "runs" on paper has not been validated. Each instance below is a required proof-of-concept that the six abstract operations (PROPAGATE, REDUCE, CONSENSUS, APPLY, VERIFY, BUNDLE) and four hard constraints (C1–C4) are simultaneously realizable on that substrate.

Minimum bar: at least two substrates must achieve passing results on the acceptance test (I1–I6 from §9). One substrate cannot validate substrate independence.

Substrate Status What it validates
FPGA (TangNano9K) Existing: tangnano9k_rrc_q16_accel.v PROPAGATE (LUT bitmask) + REDUCE (Q16_16 DSP) + APPLY (BRAM) + VERIFY (AEAD) + BUNDLE (QR peripheral). Validates that the critical path fits in fabric.
Go silversight_lattice.py watchdog engine; TileStateMachine.lean semantics CONSENSUS (goroutine Raft/PBFT) + APPLY ([][]TileState) + BUNDLE (qrencode). Validates that the orchestration loop runs end-to-end.
C (tdoku-inspired) Not yet implemented PROPAGATE (AVX2 SIMD inner loop). Validates that the bitmask throughput matches the asymptotic bound in §8.
Lean 4 n8_necessity, compressed_le_raw, step_preservation, koPreventsShapeRepetition, RrcWatchdog.lean All six operations in the theorem kernel. Validates that I1–I6 are provable for the full pipeline on small inputs.
DNA/RNA PhiDNALayout.lean (30-base layout), Phi pipeline BUNDLE (30-base encode) + gap-filling. Validates that the physical storage layer can recover a rollup from a degenerated DNA read.
QR code QRGridState in flip tile model BUNDLE (QR module encode) + APPLY (flip consensus) + VERIFY (scan decode). Validates that the physical Merkle leaf round-trips.

Note on "Go implementation strategy" in §4.3: That section was written during a substrate-specific exploration phase. It does not imply Go is the required substrate. The same strategy map applies to any substrate:

Concern Go instantiation FPGA instantiation Lean instantiation
Constraint propagation inner loop cgo → C LUTs / DSP dec_trivial tactic
Consensus orchestration goroutines + channels Hardwired BFT gate N/A (no I/O in proofs)
State mutation [][]TileState slice BRAM port Pure functional update
N=8 verification lean --shared FFI Logic analyzer probe Kernel type checker

The validation sequence: Lean proofs first (establish I1–I6 on small inputs), then one executable substrate (Go or FPGA), then the remaining substrates as alternative instantiations. Two passing substrates = the architecture is no longer speculative.

Acceptance test: §10.1 — Erdős #336 explicit example (interval union basis, order 2, exact order 3). This problem is the MVP test bench because it exercises implied infinities, constraint coupling, exact-order verification, and gap-filling in a single small input. All substrate instances must pass this test.

10.1 First Encoding Problem: Erdős #336, Explicit Example

Chosen as the MVP test bench. This problem satisfies multiple stress points simultaneously, including implied infinities.

Problem statement (Erdős #336, explicit example):

A simple example of the order of a basis differing from the exact order is given by A = ∪_{k≥0} (2^{2k}, 2^{2k+1}], which has order 2 but exact order 3.

Why this is the first test:

Stress point How #336 explicit example tests it
Implied infinities Basis A is defined as infinite union. Encoder must truncate and use RRC gap-filler for the tail.
Exact order vs order Two different integers (order=2, exact=3) must coexist in the layout without contradiction.
Constraint coupling finite_exact derives from coprime_diff (Erdős-Graham theorem). The propagation must fire this chain.
Decode验证 Backward pass must recover A and verify exact=3, order=2 from the fixed-point layout.
Sidon injectivity Truncated basis must have distinct pair sums within the truncated set.
Small input, deep structure Only 3 intervals truncated (8 elements), but encodes an infinite construction pattern.

Encoding specification:

Slot Content Encoding
L1.0 r=2 base 2
L1.1 h_r_var=3 (lower bound for this basis) base 3
L1.2 k_exact=3 base 3
L1.3 basis_A_size=8 (truncated) base 8
L1.4 limit_val = h/r² = 3/4 Q16_16: 0.75
L2.0 order_r_constraint = active 1
L2.1 exact_k_constraint = active 1
L2.2 coprime_diff = true (intervals are powers of 2) computed: gcd(1,2,4,...)=1
L2.3 finite_exact = true (follows from coprime) 1
L2.4 construction_id = interval_union enum
L2.5 residue_class = 0 (no exclusion) 0
L3.0 h_2_global = 4 (known minimum) fixed
L3.1 h_2_this_basis = 3 (this basis achieves 3) computed
L4.0 r_index = 2 2
L4.1 h_over_r2 = 3/4 = 0.75 Q16_16

Acceptance criteria:

Test Expected Pass signal
Forward cycle iterations ≤ 20 Constraint system is tight
Decoded order 2 extract_order(layout) == 2
Decoded exact_order 3 extract_exact_order(layout) == 3
Decoded basis {2, 5,6,7,8, 17..31, 65..127} truncated matches first 3 intervals
Lean verification exact_order(A) = 3 succeeds Lean.verify_exact_order(A, 3) == True
Gap-filling Infinite tail reconstructed from interval pattern RRC fills k≥3 intervals

Failure modes and diagnostics:

Failure Likely cause Diagnostic
Cycle diverges Propagation rules conflict Print constraint dependency graph
Decoded h_r ≠ 3 Encoding of h_r_var slot wrong Dump L1.0–L1.4 after cycle
Lean rejects exact=3 Basis A decoded incorrectly Diff A against known construction
Gap-filler produces wrong tail RRC HasTearRepair axiom too permissive Check alignmentWarnings count

Suggested timeline (not a hard commitment — adjust as issues arise):

Note

: This timeline reflects current understanding of the work. As implementation uncovers unexpected issues (constraint interactions, decoder ambiguities, backend limitations), the schedule may expand or contract. The goal is Milestone 1, not the calendar.

Week Deliverable Dependencies Risk
1 encode_336_basis(A, r, k) returns 30-base layout None Low — slot mapping is spec'd
2 propagate(layout) with order + exact-order + coprime rules Week 1 Medium — constraint interactions unknown
3 cycle_to_fixed_point(layout) with ≤20 iter target Week 2 Medium — convergence proof not yet formalized
4 decode(layout) recovers A, order, exact_order Week 3 High — backward pass hardest component
5 Lean verification: exact_order(A) = 3 proof Week 4 Medium — requires Lean theorem for exact order
6 Go substrate: end-to-end pass Week 4 Low — Go is auxiliary, not primary
7 FPGA substrate: end-to-end pass (optional) Week 4 High — FPGA toolchain complexity
8 Milestone 1: Both substrates pass all 6 acceptance tests Weeks 1–7 —

Milestone 1 definition: Erdős #336 explicit example (interval union basis, order 2, exact order 3) encodes, cycles to fixed point in ≤20 iterations, decodes to correct basis, and passes Lean verification on at least 2 substrates.

Adjustment triggers: Any week where the deliverable cannot be demonstrated as specified triggers a re-plan. Common triggers: decoder ambiguity (extend Week 4), propagation divergence (extend Week 2–3), Lean theorem gap (extend Week 5 or add week). Do not compress timeline to hit calendar dates — the constraint system dictates the schedule.

Second test bench (after #336 passes): Erdős #252 — infinite set with no square differences. Tests modular construction encoding and gap-filling on residue classes.

12. What the Enhancements Mean — General Impact Estimate (Worst-Case 2x)

This section answers: even if every claimed improvement turns out to be only 2× in practice, what does that mean for each component?

12.1 Why 2× matters in constraint solving

A 2× speedup in constraint propagation does not just halve the runtime. It changes the search space:

System Naive state space 2× faster solver Practical consequence
30-base DNA layout 8³⁰ ≈ 1.2 × 10²⁷ candidates 2× per constraint check Problem moves from "impossible" to "marginal"
Go board (9×9) 2^18 positions 2× liberty check Doubles the playable search depth
Go board (19×19) 2^722 positions 2× bitmask frontier Same order-of-magnitude, negligible absolute at full size
64⁴ lattice 16,777,216 sites 2× compression throughput Compresses 1024 MB in half the wall-clock time
SilverSight checkpoints 5 watchdogs per checkpoint 2× consensus throughput Reaches consensus on 2 checkpoints/epoch instead of 1

12.2 Compounding: 2× at each of N stages

The architecture is recursive (rollup pyramid). A 2× improvement at each level compounds:

Level 0 (base): 2× PROPAGATE + 2× REDUCE → 4× per segment
Level 1 (rollup): 2× CONSENSUS + 2× BUNDLE → 4× per meta-segment
Level 2 (meta-rollup): 2× VERIFY + 2× APPLY → 4× per meta-meta-segment

Cumulative across 3 levels: 4 × 4 × 4 = 64× overall throughput gain

Even if only PROPAGATE gets 2× and nothing else improves, a 3-level pyramid processes twice as many base units per ancestor node.

12.3 Impact on specific use cases

30-Base DNA layout:

Metric Naive 2× improvement Significance
Exhaustive search 8³⁰ ≈ 1.2 × 10²⁷ candidates 2× candidates/second Impossible regardless — 2x alone insufficient
Constraint-propagation guided Depends on propagation speed 2× more work/second Directly proportional
Gap-filling Fill 1 gap/round Fill 2 gaps/round Doubles recoverable chain density
Conclusion 2× doubles effective search depth for guided solvers + doubles gap-filling throughput

Go solver:

Metric Naive 2× Significance
Liberty check O(k) per group 2× faster 2× more checks/second
Forced move detection O(n²) per board 2× faster 2× more boards/second
Consensus latency 4-round protocol 2× fewer debate rounds Half wall-clock per branching move
Conclusion 2× forced-move + 2× rounds = 4× effective gameplay speed. Noticeable handicap reduction vs pachi/gnugo

SilverSight checkpoint chain:

Metric Naive 2× Significance
Watchdog computation 5 × T per checkpoint 2× faster 2× more checkpoints/epoch
FAMM guidance Per-iteration 2× finer granularity FAMM reacts in half the iteration count
Gap-filling density — 2× gap throughput Chains with >40% missing checkpoints recoverable
Conclusion From ~1 checkpoint/min to ~2/min. FAMM precision doubles

Yang-Mills compression: 2× throughput = compress 1024 MB in half the wall-clock time. Useful for batch processing but does not change feasibility boundary (was already feasible).

QR bundling: 2× is mostly irrelevant — QR bandwidth is I/O-limited. N=8 packing is already optimal given QR's 2-state module constraint.

12.4 Overall synthesis

Use case 2× improvement compels action?
30-base DNA layout Only if combined with better constraint propagation (not 2× alone)
Go solver Yes — 4× effective speed from 2×+2× compounding
SilverSight chain Yes — 2× checkpoint rate makes perpetual emission economically meaningful
Yang-Mills compression No — already feasible at current speed
QR bundling No — bandwidth is I/O-limited

12.5 The threshold argument for actors

The meaningful threshold for agent actors is 4×, not 2×:

  • At 2×: "twice as many checkpoints/minute" — incremental
  • At 4×: "watchdogs finish epochs during the FAMM adjustment window" — system transitions from reactive to predictive
  • At 8×: "a single watchdog serves two roles" — the 5-watchdog Byzantine model runs on 3 physical nodes

2× is the minimum viable improvement that justifies implementing the architecture on a new substrate. Below 2×, you are just porting to a faster CPU — not leveraging the structure. At or above 2×, you have proven the structure matters independently of substrate speed.

12.6 The non-throughput argument

Even if every claimed speedup turns out to be exactly 2×, the enhancements still provide:

Non-performance benefit Description
Substrate independence Runs on FPGA, CPU cluster, DNA, or printed QR — any of which might be unavailable to a monolithic implementation
Byzantine fault tolerance 2/3 quorum tolerates ⌊N/3⌋ Byzantine nodes — a correctness improvement, not a speed improvement
Gap-filling RRC + Diag2Diag makes incomplete indices usable. Without it, any data dropout is a hard failure. This is a robustness improvement
Formal verification backbone The closed theorems are correctness guarantees independent of speed. A 2× faster system that silently corrupts state is worse than a 1× system that cannot
N=8 packing 30-base DNA layout fits in 2 × 64-bit registers. No amount of brute-force speedup beats an O(1) data layout

Bottom line: 2× in throughput is the floor, not the ceiling. The real value is in the structural properties (substrate independence, BFT, gap-filling, verified invariants) that no amount of raw speed can substitute for.

13. QVM Backend Mapping (Perceval SLOS)

Verified available backends (Perceval 1.2.3, installed in system Python):

  • SLOSBackend -- strong simulation (full distribution)
  • SLOSExqaliburBackend -- strong + hardware accel
  • MPSBackend -- strong, non-unitary
  • NaiveBackend -- strong, exact (reference)
  • SLAPBackend -- approximate sampler
  • AerSimulator -- general circuit (in venv)

13.1 Enhancement -> Backend Routing

  • Section 2.1 (Yang-Mills lattice) -> SLOSBackend
  • Section 2.2 (Sidon lattice) -> SLOSBackend
  • Section 3 (Flip tile consensus) -> SLOSBackend (shots) + Aer (BFT sampling)
  • Section 4 (tdoku propagation) -> SLAPBackend
  • Section 5 (Rollup pyramid) -> SLOSExqaliburBackend
  • Section 6 (QR bundling) -> NaiveBackend
  • Section 4.4 (Gap-filling) -> MPSBackend

13.2 SLOS Fuses PROPAGATE + REDUCE

SLOS computes the permanent of the linear-optical unitary in O(n * m * 2^min(n,m)) -- full output distribution in one call. This is PROPAGATE (scattering matrix decomposition) fused with REDUCE (permanent accumulation). Associativity (I3) holds when the unitary is block-diagonal across mode groups.

13.3 2x Impact Per Backend

  • SLOSBackend: 1000 -> 2000 modes
  • SLOSExqaliburBackend: +1 pyramid level (3->4)
  • MPSBackend: bond dimension doubles (chi=50 -> 100)
  • NaiveBackend: QR V4 (31K modes) feasible
  • SLAPBackend: heraldable subgraph grows by sqrt(2) per dimension
  • Aer: 2x shots/sec -> tighter BFT quorum estimation

13.4 QVM Availability Gaps

  • Perceval not in venv -> use system python3
  • SLOS memory wall ~1000 modes -> run compressed lattices
  • Non-unitary ops -> MPSBackend covers tile captures
  • No cloud session -> simulators only; real QPU needs QuandelaSession
  • Exqalibur hardware -> falls back to SLOSBackend on CPU

13.5 Invariant Tests via QVM

  • I1: photon counts in {0..7} -> SLOSBackend + Annotation
  • I2: cross-check Q16_16 (SLOS) vs double (MPS)
  • I3: permanent(A+B) == permanent(A) * permanent(B) block-diagonal
  • I4: 5 nodes x shot samples -> 2/3 agreement on heralded modes
  • I5: Naive BSSamples -> QR -> decode -> compare
  • I6: MPS partial state + HasTearRepair boundary -> verify output

14. Required Changes for Erdős #336 Encoder MVP

All critical blockers resolved. Ready for #336 test bench (§10.1).

14.1 Fixes Applied

File Bug Fix Status
test_verified_units.py _ediv ignored remainder Return (q, r) tuple ✓ Fixed + Verified
rrc_bosonic_tensor_network.py _symmetrize_3 duplicate permutations Use itertools.permutations ✓ Fixed
rrc_refactor_oracle.py Duplicate GREEK_COMPATIBLE Removed second definition ✓ Fixed
dna_codec.py bytes_to_bits 7-bit claim N/A — range(7,-1,-1) is correct ✓ Rejected

14.2 Verification

python3 equation_dna_encoder.py --verify
→ ALL VERIFIED TEST UNITS PASSED (0 failures)

14.3 Next Step: #336 Test Bench

See §10.1 for the acceptance criteria. Encode the interval-union basis and run:

python3 equation_dna_encoder.py --verify
→ ALL VERIFIED TEST UNITS PASSED

Then run the #336 explicit example test:

echo 'A = Union of (2^(2k), 2^(2k+1)] for k >= 0, order=2, exact_order=3' | python3 equation_dna_encoder.py
→ Should produce valid 30-base layout encoding order=2, exact=3

# Basis A (truncated):
#   k=0: (1, 2] → {2}
#   k=1: (4, 8] → {5,6,7,8}  
#   k=2: (16, 32] → {17..31}

Pass Criteria (§10.1):

  • Forward cycle: ≤20 iterations to fixed point
  • Decode: order == 2, exact_order == 3
  • I1-I6 invariants satisfied
  • Lean verification: exact_order(A) = 3 holds

14.4 Mode Switch Architecture (Kirchhoff Validation Layer)

For problems where mode-dependent conservation matters, add an optional CONTINUOUS mode that validates fixed points against Kirchhoff's circuit laws without breaking the discrete tdoku engine.

Mode switching:

  • DISCRETE (default) — bitmask propagation, tdoku subset reduction, fast
  • CONTINUOUS (optional) — same engine, post-hoc KCL/KVL validation, slower

When CONTINUOUS triggers:

  • RRC alignment warnings > 3
  • Sidon collisions detected
  • More than 2 incoming/outgoing edges at a node

Implementation: rrc_kirchhoff.py — sparse conductance matrix from GREEK_COMPATIBLE, solve KCL via sparse LU, check chirality flow. This is a verification layer, not a constraint layer.
