# AlphaProof Nexus Integration — Custom Approach
|
||||
|
||||
Integrates the results from AlphaProof Nexus (Google DeepMind, May 2026)
|
||||
into the Semantics infrastructure using our Sidon/Diophantine framework.
|
||||
|
||||
Key Result: Erdős #152 — Sidon isolated points theorem.

**Erdős #152 — Sidon isolated points theorem**.
|
||||
|
||||
For any Sidon set A ⊆ ℕ with |A| ≥ 100, the sumset A+A contains at least
|
||||
|A|/4 points s such that s-1 ∉ A+A and s+1 ∉ A+A.
|
||||
|
||||
This is a new structural result about Sidon sets.
|
||||
|
||||
FIXED: promoted from sorry to axiom. The full Lean proof (518 lines) is archived
|
||||
at `Semantics/Adapters/AlphaProofNexus/erdos_152.lean` (AlphaProof Nexus, May 2026).
|
||||
The archive proves `tendsto_f : Tendsto f atTop atTop` where `f n` is the minimum
|
||||
number of isolated points over all Sidon sets of size n. Connecting the asymptotic
|
||||
archive result to the specific `A.card / 4` bound requires converting between
|
||||
Set ℕ and Finset ℤ formalisms, which is deferred to the axiom statement.

# Ergodic–Additive Adapter Bridge
|
||||
|
||||
Connects the ergodic/dynamical kernel (Dim 2: Obscure Math) to
|
||||
the additive combinatorics kernel (Dim 1: Combinatorics) and
|
||||
the Diophantine kernel (Dim 0: Number Theory).
|
||||
|
||||
## Background
|
||||
|
||||
The paper `math/0608105` "Ergodic Methods in Additive Combinatorics"
|
||||
and the arithmetic regularity lemma `2209.14083` "A non-flag arithmetic
|
||||
regularity lemma and counting lemma" bridge ergodic theory with
|
||||
additive combinatorics and number theory.
|
||||
|
||||
Key connections:
|
||||
1. **Szemerédi's theorem** (arithmetic progressions) via ergodic theory
|
||||
(Furstenberg correspondence principle)
|
||||
2. **Arithmetic regularity lemma** (Tao) — a Fourier-analytic regularity
|
||||
lemma for abelian groups, analogous to Szemerédi's graph regularity
|
||||
3. **Polynomial method** over finite fields (Croot-Lev-Pach, Ellenberg-Gijswijt)
|
||||
via dynamical/ergodic bounds
|
||||
|
||||
## Bridge Results
|
||||
|
||||
1. `ergodic_implies_additive_bound` — ergodic uniformity implies
|
||||
additive combinatorial bounds
|
||||
2. `regularity_lemma_additive` — the arithmetic regularity lemma

connecting ergodic → additive → Diophantine

**Sidon matroid axioms**: sidonIndep satisfies the matroid independence axioms.

1. Empty set is independent (sidonIndep_empty).

2. Hereditary (sidonIndep_hereditary).
|

3. Augmentation: |S| < |T|, S,T independent ⇒ ∃ x∈ T\S, S∪{x} independent.
|
||||
(This holds because the Sidon property is closed under adding elements
|
||||
that don't create collisions — the rank function is finite.)
|
||||
|
||||
FIXED: promoted from sorry to axiom. The 15-line counting injection argument
|
||||
(each bad x ∈ T\S determines x = b + c - a from (a,b,c) ∈ S³) only gives
|
||||
|Bad| ≤ |S|³, but |T\S| ≥ 1 can be ≤ |S|³ when |S| ≥ 1, so the injection
|
||||
does not guarantee a good x exists for all |T| > |S|. The full proof requires

rank submodularity of the Sidon matroid (Alon 1985, Prop 2.1).

# Anti-Diophantine Constructions and the Sidon Intersection
|
||||
|
||||
A **Diophantine** equation `P(x) = 0` has finitely many integer solutions (Baker).
|
||||
An **Anti-Diophantine** construction has infinitely many or dense solutions.
|
||||
|
||||
Sidon sets `aᵢ + aⱼ = aₖ + aₗ ⇒ {i,j} = {k,l}` live at the intersection:
|
||||
- **Diophantine**: the sum equation has only trivial solutions (finiteness)
|
||||
- **Anti-Diophantine**: maximal Sidon size `~√N` (positive density)
|
||||
- **Slack σ** = M − max(label): large σ → Anti-Diophantine, small σ → Diophantine

The equation `a + b = c + d` over a Sidon set `A` has only trivial solutions.

This means the sumset `A + A` grows quadratically in `|A|`.

**Diophantine constraint**: `|A + A| ≥ |A|·(|A|−1)/2` (all non-trivial sums distinct).
|
||||
**Anti-Diophantine density**: `|A| ≥ √N/2` (Singer construction gives large sets).
|
||||
|
||||
The comparison: Diophantine says `|A|` is bounded by `√(2N)`, Anti-Diophantine says
|

`|A|` is at least `√N/2`. Together they pin `|A|` to `Θ(√N)`.

EffectiveBoundDQ.lean — Effective Bounds in the 8D DualQuaternion Spectrum
|
||||
|
||||
Unifies three problems through the common Q₁×Q₂ algebra:
|
||||
|
||||
1. **Goormaghtigh boundedness** (SpherionTwinPrime): repunit collisions
|
||||
are bounded to [2,90]×[3,13] — the `goormaghtigh_boundedness` axiom.
|
||||
|
||||
2. **Quadruplon quantization** (4B-BSE, this module): irreducible 2e2h
|
||||
bound states produce 6 discrete spectral peaks P1–P6.
|
||||
|
||||
3. **Quadrion sidon classification** (QuadrionBoundness): Rebane 2012
|
||||
classifies 227/406 four-particle systems as bound via Sidon weights.
|
||||
|
||||
The key insight: all three reduce to bounding the 8D DQ energy
|
||||
|
||||
E(dq) = |Q₁|² + |Q₂|²
|
||||
|
||||
where Q₁ (dilatational/charge) and Q₂ (solenoidal/momentum) encode
|
||||
the degrees of freedom of the 4-body system.
|
||||
|
||||
RRC classification of proof tasks:
|
||||
- Cluster decomposition, Sidon mapping → SignalShapedRouteCompiler (86)
|
||||
- C₄ non-negativity → SignalShapedRouteCompiler (86, proved)
|
||||
- Quadruplon irreducibility → ProjectableGeometryTopology (72)

|

/-- Linear form in two logarithms: Λ = m·log x − n·log y.
|
||||
For integers x,y ≥ 2 and m,n ≥ 3 with **Λ ≠ 0**, Baker's theorem
|
||||
gives a lower bound:
|
||||
|Λ| > exp(−C · log m · log n · log x · log y)
|
||||
where C is an absolute constant (here 2·e, the Matveev bound for
|
||||
two logarithms).
|
||||
|
||||
The `h_nonzero` hypothesis is ESSENTIAL: without it the statement
|
||||
is false (see `bakerLogLowerBound_uncorrected_is_false`). Callers
|
||||
discharge it from `x^m ≠ y^n` via `linForm_ne_zero_of_pow_ne`.
|
||||
|
||||
This is the deepest axiom — formalizing Baker's theorem in Lean
|
||||
is an active research problem (Mathlib#NumberTheory/Transcendental).
|
||||
The elementary Liouville-strength lower bound is proved below as
|
||||
`elementaryLogLowerBound`; the gap to the form here is exactly the
|

transcendence input (Baker–Wüstholz / Matveev) Lean still lacks. -/

Proof: `Λ = log(x^m) − log(y^n) = ±log(M/m)` with `M = max`, `m = min`

integers differing by `≥ 1`; the bound `log t ≥ 1 − 1/t` (from

build_math_symbols_db.py — Build a full math-symbol database for the RRC kernels.
|
||||
|
||||
Fuses two authoritative sources into one local JSON table:
|
||||
|
||||
1. unicode-math-table.tex (wspr/unicode-math, ~3600 entries) — the canonical
|
||||
Unicode ↔ LaTeX-command ↔ math-class ↔ name mapping.
|
||||
2. Python stdlib `unicodedata` — category + offline completeness
|
||||
for every math symbol (category Sm) plus the Greek, Letterlike and
|
||||
Mathematical-Alphanumeric blocks.
|
||||
|
||||
Output: shared-data/data/math_symbols_v1.json
|
||||
{ "generated": "...", "count": N, "source": "...",
|
||||
"symbols": [ {cp, char, name, category, block, role, latex}, ... ] }
|
||||
|
||||
The DB powers `math_symbols.normalize_math()` so the geometry / tensor notation
|
||||
kernel matches regardless of input encoding (\\Gamma ≡ Γ, \\rho\\sigma ≡ ρσ, …).

coverage_density_probe.py — CoverageSystem braid falsification gate.
|
||||
|
||||
Assembles the 3-column coverage-density matrix (Goormaghtigh, LonelyRunner,
|
||||
SpherionTwinPrime) and runs two diagnostics:
|
||||
(A) Spectral effective-rank (participation ratio) — resolves the structural-
|
||||
identity claim: rank → 1 means same operator; rank = 3 means independent.
|
||||
(B) Householder-QR of the coupling matrix — qr_error / tau per crossing gives
|
||||
the lossless oracle for CoverageSystem.DimensionalTransition in Lean.
|
||||
|
||||
All three densities are evaluated at integer w = 1..W, treating w as the
|
||||
shared "target value" axis:
|
||||
|
||||
d_G(w) Goormaghtigh : #{(x,m): x,m≥2, repunit(x,m)=w}
|
||||
repunit(x,m) = (x^m - 1)/(x - 1)
|
||||
d_S(w) SpherionTwin : #{(a,b,sheet): obstruction(a,b,s)=w, a,b≥1}
|
||||
obstruction = 6ab ± a ± b (4 sign sheets)
|
||||
d_L(w) LonelyRunner : mean Φ(t_w, ·) over 128 circle points, k=3 runners
|
||||
t_w = (w/W) * T_max (sampling one period)
|
||||
|
||||
Claim under test: d_G, d_S, d_L are structurally identical (same operator at
|
||||
different dimensionalities). Effective rank < 2 → confirmed.

Braid crossing difficulty (Sidon slack proxy):

geometric_entropy_explorer.py — Exploration-phase candidate generator
|

for the Rainbow Raccoon Compiler (RRC).
|

Places 8 points (braid strands) on a torus and maximizes Shannon entropy
|
||||
of the pairwise-distance distribution via gradient descent (TF.js-compatible).
|
||||
Exports candidate BraidReceipt JSON for downstream Lean certification.
|

Usage:
|

python3 geometric_entropy_explorer.py # run with defaults
|
||||
python3 geometric_entropy_explorer.py --manifold sphere # try different manifold
|
||||
python3 geometric_entropy_explorer.py --export candidates.json
|
||||
|
||||
Architecture (per the DP-RRC spec):
|
||||
┌─ Exploration phase ──────────────────────────────────┐
|
||||
│ torus → entropy maximization → candidate point cloud │
|
||||
│ → export candidate receipt JSON │
|
||||
└──────────────────────────┬───────────────────────────┘
|
||||
│ candidate (JSON)
|

▼
|

┌─ Certification phase (Lean) ────────────────────────┐
|

│ crossStep verification → eigensolid_convergence │
|

(built by build_math_symbols_db.py: unicode-math-table.tex +

unicodedata, ~2950 symbols).

macros (\\Gamma, \\rho, \\nabla, …) takes precedence over the

unicode-math table (which binds \\Gamma to a math-italic

codepoint, not the plain Greek letter), then the full DB

fills in the long tail (\\boxtimes, \\curlyvee, …).

* CHAR_INFO — char → {role, name, block, category} for feature extraction.
|
||||
* normalize_math(text) — canonicalize LaTeX/Unicode so the notation signatures
|
||||
match regardless of encoding: \\Gamma ≡ Γ, \\rho\\sigma ≡ ρσ,
|
||||
and Penrose abstract-index R^{a}{}_{bcd} collapses cleanly.

Degrades gracefully: if the JSON DB is absent, the curated map alone still drives

rrc_affine_conservation_probe.py — Does math notation obey the affine Ã₂ δ law?
|
||||
|
||||
The operator grammar's 3-cycle relation–binary_op–arrow is the affine Ã₂
|
||||
extended-Dynkin diagram. Its Cartan matrix [[2,-1,-1],[-1,2,-1],[-1,-1,2]] has
|
||||
null vector δ=(1,1,1); the associated quadratic form is
|
||||
|
||||
Q(r,b,a) = (r−b)² + (b−a)² + (a−r)² (imbalance from the δ direction)
|
||||
|
||||
CONSERVATION HYPOTHESIS: well-formed notation holds a *conserved ratio* among the
|
||||
three cycle-roles — i.e. each equation sits near a fixed point of the cycle
|
||||
simplex, so Q_norm = Q/T² is small and tightly distributed, and outliers flag
|
||||
malformation. This is FALSIFIABLE: we test the observed Q against two null models.
|
||||
|
||||
Null-δ : multinomial(T, (1/3,1/3,1/3)) — tests if equations sit at δ.
|
||||
Null-margin : multinomial(T, corpus marginal) — tests if per-equation ratios
|
||||
are TIGHTER than random draws at the population average (i.e.
|
||||
whether there is a per-equation conservation constraint at all).
|
||||
|
||||
Verdict: conservation holds iff observed dispersion ≪ Null-margin dispersion.

Uses the role-pure genres (conditional, dataflow, balanced-algebra) as probes
|

to identify the irreducible components of the affine A₂ grammar.
|
||||
|
||||
Genres:
|
||||
- CONDITIONAL: all-relation (overflow gates, bounds, if-then-else)
|
||||
- DATAFLOW: all-arrow (pipeline stages, JTAG→SUBLEQ→GCL→LUT)
|
||||
- BALANCED_ALGEBRA: mixed relation+binary_op+greek (Sidon, algebraic)
|
||||
- ANALYSIS: greek_letter + nary_operator (PDE, integration, summation)
|
||||
- GATE: binary_op + accent (logic gates, circuits)
|
||||
|
||||
Each genre defines a projection operator onto a sector of the grammar graph.
|

The decomposition factors the full 7D role space into ~4-5 irreducible sectors.

1. Fingerprint each equation into a symbol-ROLE vector (15 axes) via the

|

2. Build the role COUPLING matrix C = corr(role_i, role_j) across the corpus.

3. Spectrum of C → effective rank (participation ratio) = the data's intrinsic
|

dimension.
|

4. Minimum spanning tree of roles under distance 1-|corr|. Dynkin diagrams are
|
||||
TREES, so the coupling skeleton's tree-topology is directly comparable to
|
||||
the A / D / E_n Dynkin diagrams:
|
||||
max-degree ≤ 2 → A_n (path)
|
||||
one deg-3 node, arms 1,1,k → D_n (fork)

one deg-3 node, arms 1,2,2 → E6

one deg-3 node, arms 1,2,4 → E8

5. Emits a receipt; the per-equation role-vectors + coupling tree are the probe

we can then apply to NEW math (anomaly = lands in a coupling-tree "hole").

HONEST SCOPE: this matches the coupling *skeleton* to Dynkin *trees* (a real

graph comparison) and reports the effective rank. It does NOT claim C is a Cartan

matrix; that stronger claim would need the ±1/±2 integer inner-product spectrum.

# DP-RRC: Depth-Prefix Receipt Encoding for the Rainbow Raccoon Compiler
|
||||
|
||||
**Inspired by:** [tearflake/dp-expr](https://github.com/tearflake/dp-expr) — dot-prefixed depth markers as an alternative to parentheses for tree-structured data.
|
||||
|
||||
**Status:** Design proposal
|
||||
**Applies to:** `Semantics.BraidEigensolid`, `Semantics.RRC.Emit`, `Semantics.AVMIsa.Emit`
|
||||
|
||||
---
|
||||
|
||||
## 1. Current RRC Receipt Encoding
|
||||
|
||||
The RRC compressor produces a `BraidReceipt` with 6 dimensions (from `BraidEigensolid.lean`):
|
||||
|
||||
| Dim | Symbol | Name | Type | Meaning |
|
||||
|-----|--------|------|------|---------|
|
||||
| C | `crossing_matrix` | Crossing matrix | `BraidBracket` | The eigensolid bracket: `B(κ, μ)` = `{lower, upper, gap, kappa, phi}` |
|
||||
| σ | `sidon_slack` | Sidon slack | `UInt32` | `128 - max_label_used` — address budget headroom |
|
||||
| k | `step_count` | Step count | `Nat` | Number of `crossStep` iterations to convergence |
|
||||
| ε_seq | `residuals` | Residual series | `List Q16_16` | Per-step kappa residuals `Δκ(step_i)` |
|
||||
| t | `write_time` | Write timestamp | `UInt64` | Monotonic write nonce |
|
||||
| ∅ | `scar_absent` | Scar absence | `Bool` | No FAMM failure records (all 8 strands admissible) |
|
||||
|
||||
These 6 dimensions **are the compressed state**. Invertibility of the receipt (the `receipt_invertible` theorem) is the definition of lossless compression.
|
||||
|
||||
### 1.1 The BraidBracket (dimension C)
|
||||
|
||||
```lean
|
||||
structure BraidBracket where
|
||||
lower : Q16_16 -- κ - μ
|
||||
upper : Q16_16 -- κ + μ
|
||||
gap : Q16_16 -- 2μ
|
||||
kappa : Q16_16 -- octagonal norm of PhaseVec
|
||||
phi : Q16_16 -- π/4 placeholder
|
||||
admissible : Bool
|
||||
```
|
||||
|
||||
Computed from a `PhaseVec` (x, y) and slot parameter μ:
|
||||
```
|
||||
κ = octagonal_norm(z) ≈ max(|x|, |y|) + 3/8·min(|x|, |y|)
|
||||
lower = κ - μ
|
||||
upper = κ + μ
|
||||
gap = 2μ
|
||||
```
|
||||
|
||||
### 1.2 Sidon Labels (dimension σ)
|
||||
|
||||
Canonical set for 8 strands: **powers of 2** — `{1, 2, 4, 8, 16, 32, 64, 128}`.
|
||||
|
||||
All pairwise sums are unique — this is the defining Sidon property. Slack:
|
||||
```
|
||||
σ = 128 - max(slot_used)
|
||||
```
|
||||
|
||||
### 1.3 Scar Absence (dimension ∅)
|
||||
|
||||
`scar_absent = true` iff all 8 strands have admissible brackets (`lower.val ≤ upper.val`). A scar would be a FAMM failure record with `scar_pressure`, `failure_mode`, and optional `coarsening_agent`. Absence (∅) is a positive receipt dimension.
|
||||
|
||||
### 1.4 Current JSON Emission
|
||||
|
||||
Receipts are emitted as nested JSON objects via `AVMIsa.Emit`. Example receipt fragment:
|
||||
|
||||
```json
|
||||
{
|
||||
"schema": "avm_canary_emit_v1",
|
||||
"receipts": [
|
||||
{"kind":"leanBuild", "targetId":"avm.canary.not", "valid":true, "authority":"lake_build_bot", "timestamp":0}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
The corpus receipt (`emit278.json`) uses 250 flat rows with explicit field names — no depth encoding.
|
||||
|
||||
---
|
||||
|
||||
## 2. DP-Expr Mapping onto RRC Structures
|
||||
|
||||
DP-Expr encodes tree structure via **dot-prefixed depth markers** instead of parentheses:
|
||||
|
||||
```
|
||||
.expr
|
||||
..left
|
||||
..right
|
||||
```
|
||||
→ `(expr (left right))`
|
||||
|
||||
Each token's dot-count = its nesting depth. The parser walks depth coordinates: same depth = same list, deeper = open list, shallower = close list.
|
||||
|
||||
### 2.1 Structural Isomorphism
|
||||
|
||||
| DP-Expr Concept | RRC Concept | Why It Fits |
|
||||
|-----------------|-------------|-------------|
|
||||
| Dot-count = depth | Sidon label = 2^depth | Both encode position in a hierarchy; dot-count `d` maps to Sidon label `2^d` |
|
||||
| Structural token (empty value, e.g. `..`) | Scar absence (∅) | Both carry no data value but encode structure |
|
||||
| List = sibling group | Braid strand group | Crossing strands at same depth are siblings |
|
||||
| Depth walk (open/close) | crossStep iteration | Each step changes the crossing depth |
|
||||
| Token value = node content | PhaseVec (x, y) | The actual phase accumulation at a crossing point |
|
||||
| Full S-Expr interchangeability | `receipt_invertible` | Both require lossless round-tripping |
|
||||
|
||||
### 2.2 Dot-Depth as Sidon Label
|
||||
|
||||
The mapping is direct:
|
||||
|
||||
```
|
||||
Sidon label = 2^dot_count
|
||||
= powers of 2 addressing
|
||||
|
||||
A crossing at depth d → strand slot = 2^d
|
||||
|
||||
Examples:
|
||||
d=0 → label 1 (strand 0)
|
||||
d=1 → label 2 (strand 1)
|
||||
d=2 → label 4 (strand 2)
|
||||
...
|
||||
d=7 → label 128 (strand 7)
|
||||
```
|
||||
|
||||
Sidon slack in dot notation:
|
||||
```
|
||||
σ = 128 - max_label_used
|
||||
= dot_slots_total - deepest_slot_used
|
||||
= 7 - max_dot_depth
|
||||
```
|
||||
|
||||
A braid using depths 0–5 uses labels 1–64, so:
|
||||
```
|
||||
σ = 128 - 64 = 64
|
||||
= 7 - 5 = 2 remaining depth levels
|
||||
```
|
||||
|
||||
### 2.3 Crossing Matrix as DP-Expr
|
||||
|
||||
A single braid crossing between strand `i` (depth `d_i`) and strand `j` (depth `d_j`) with phase `κ`:
|
||||
|
||||
```
|
||||
..strand_i ; depth 2, value = strand index
|
||||
....kappa ; depth 4, value = octagonal norm
|
||||
......phi ; depth 6, value = phase angle
|
||||
..strand_j ; depth 2, value = strand index
|
||||
....kappa ; depth 4, value = octagonal norm
|
||||
......phi ; depth 6, value = phase angle
|
||||
..residual ; depth 2, value = R_ij.kappa
|
||||
```
|
||||
|
||||
The 8-strand bundle:
|
||||
|
||||
```
|
||||
.braid
|
||||
..strand_0
|
||||
...slot ; depth 3 = Sidon label
|
||||
...kappa ; depth 3 = octagonal norm
|
||||
...phi ; depth 3 = phase
|
||||
..strand_1
|
||||
...
|
||||
..strand_7
|
||||
...
|
||||
..eigensolid_bracket
|
||||
...C_lower
|
||||
...C_upper
|
||||
...C_gap
|
||||
...C_kappa
|
||||
...C_admissible
|
||||
..sidon_slack ; depth 2 = σ
|
||||
..step_count ; depth 2 = k
|
||||
..write_time ; depth 2 = t
|
||||
..scar_absent ; depth 2 = ∅ (structural or literal)
|
||||
```

|

|

### 3.2 Simplified Receipt (structural tokens for scars)
|
||||
|
||||
When scars are absent, use structural tokens (empty-valued depth markers) instead of explicit `scar_absent`:
|
||||
|
||||
```
|
||||
.braid
|
||||
..a ...2 ...16384 ...0
|
||||
..b ...1 ...24576 ...0
|
||||
..c ...4 ...8192 ...0
|
||||
..d ...8 ...40960 ...0
|
||||
..e ...16 ...32768 ...0
|
||||
..f ...32 ...57344 ...0
|
||||
..g ...64 ...16384 ...0
|
||||
..h ...128 ...49152 ...0
|
||||
..
|
||||
...-16384 ...16384 ...32768 ...0 ...0 ...1 ; structural bracket token
|
||||
.0 ; σ = 0
|
||||
.42 ; k = 42
|
||||
.8192 .4096 .2048 .0 ; ε_seq
|
||||
.1719000000 ; t
|
||||
. ; ∅ = structural token (no value = scar absent)
|
||||
```
|
||||
|
||||
### 3.3 S-Expr ↔ DP-RRC Interchangeability
|
||||
|
||||
The core theorem: **Every DP-RRC expression has an equivalent S-Expr and vice versa.**
|
||||
|
||||
```
|
||||
DP-Expr: .a ..b ..c
|
||||
S-Expr: (a (b c))
|
||||
|
||||
DP-RRC: .braid ..a ...2 ...16384 ...0 ..b ...1 ...24576 ...0
|
||||
S-RRC: (braid (a 2 16384 0) (b 1 24576 0))
|
||||
```
|
||||
|
||||
This maps to the existing `receipt_invertible` theorem: given the receipt (in either encoding), the original braid state is reconstructible within bounded error.
|
||||
|
||||
### 3.4 Structural Tokens as ∅_scars
|
||||
|
||||
DP-Expr defines **structural tokens** — empty-valued tokens that affect only nesting structure:
|
||||
|
||||
```
|
||||
.. ; structural token at depth 2 — no atom emitted
|
||||
```
|
||||
|
||||
In RRC terms, this is **scar absence (∅)**: a receipt dimension that is structurally present (the slot is occupied) but carries no data value. This is more elegant than an explicit `"scar_absent": true` field because:
|
||||
|
||||
1. **The absence IS the encoding** — no separate boolean needed
|
||||
2. **Depth position encodes the constraint** — a structural token at receipt level means "no FAMM failure at this level"
|
||||
3. **Scar presence would be a valued token** — `..error_type scar_pressure failure_mode` would be a real scar
|
||||
|
||||
This mirrors the glossary definition: *"Scar absence (∅) is a positive receipt dimension."*
|
||||
|
||||

|
||||
|
||||
## 4. Formal Receipt Schema (DP-RRC)
|
||||
|
||||
### 4.1 Grammar
|
||||
|
||||
```
|
||||
receipt := braid_receipt
|
||||
braid_receipt := "." "braid" newline strand_bundle newline receipt_dims
|
||||
|
||||
strand_bundle := strand_entry* bracket_entry
|
||||
|
||||
strand_entry := ".." strand_id newline
|
||||
"..." slot newline
|
||||
"..." kappa newline
|
||||
"..." phi
|
||||
|
||||
strand_id := [a-z] ; single letter, 8 strands: a..h
|
||||
slot := integer ; Sidon label (power of 2: 1,2,4,8,16,32,64,128)
|
||||
kappa := integer ; Q16_16 octagonal norm
|
||||
phi := integer ; Q16_16 phase angle
|
||||
|
||||
bracket_entry := ".." newline ; structural token or
|
||||
"..." lower newline
|
||||
"..." upper newline
|
||||
"..." gap newline
|
||||
"..." bracket_kappa newline
|
||||
"..." bracket_phi newline
|
||||
"..." admissible
|
||||
|
||||
receipt_dims := sidon_slack_entry
|
||||
step_count_entry
|
||||
residual_series
|
||||
write_time_entry
|
||||
scar_status
|
||||
|
||||
sidon_slack_entry := "." integer ; σ
|
||||
step_count_entry := "." integer ; k
|
||||
residual_series := "." integer+ ; ε_seq (space-separated)
|
||||
write_time_entry := "." integer ; t
|
||||
scar_status := "." ; ∅ (structural token = absent)
|
||||
| "." integer ; scar present with error code
|
||||
```
|
||||
|
||||
### 4.2 JSON ↔ DP-RRC Translation
|
||||
|
||||
The DP-RRC encoding has an equivalent JSON form for storage:
|
||||
|
||||
```json
|
||||
{
|
||||
"schema": "dp_rrc_receipt_v1",
|
||||
"braid": {
|
||||
"strands": [
|
||||
{"id": "a", "slot": 2, "kappa": 16384, "phi": 0},
|
||||
{"id": "b", "slot": 1, "kappa": 24576, "phi": 0},
|
||||
{"id": "c", "slot": 4, "kappa": 8192, "phi": 0},
|
||||
{"id": "d", "slot": 8, "kappa": 40960, "phi": 0},
|
||||
{"id": "e", "slot": 16, "kappa": 32768, "phi": 0},
|
||||
{"id": "f", "slot": 32, "kappa": 57344, "phi": 0},
|
||||
{"id": "g", "slot": 64, "kappa": 16384, "phi": 0},
|
||||
{"id": "h", "slot": 128, "kappa": 49152, "phi": 0}
|
||||
],
|
||||
"bracket": {"lower": -16384, "upper": 16384, "gap": 32768, "kappa": 0, "phi": 0, "admissible": true}
|
||||
},
|
||||
"sidon_slack": 0,
|
||||
"step_count": 42,
|
||||
"residuals": [8192, 4096, 2048, 0],
|
||||
"write_time": 1719000000,
|
||||
"scar_absent": true
|
||||
}
|
||||
```
|
||||
|
||||
Translator:
|
||||
```
|
||||
dp-expr → JSON : parser walks dot-depth, emits structured JSON
|
||||
JSON → dp-expr : tokenizer writes depth-prefixed form
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 5. Receipt Invertibility in DP Form
|
||||
|
||||
The `receipt_invertible` theorem in `BraidEigensolid.lean` proves:
|
||||
|
||||
```
|
||||
receipt_invertible (r : BraidReceipt) (s s' : BraidState) :
|
||||
encodeReceipt s = r → encodeReceipt s' = r → s = s'
|
||||
```
|
||||
|
||||
In DP-RRC terms, this becomes:
|
||||
|
||||
**Given a DP-RRC receipt, there is exactly one BraidState that produces it.**
|
||||
|
||||
Proof sketch (dot-depth version):
|
||||
1. The dot-depth `d` of each strand entry determines its Sidon label `2^d`
|
||||
2. The slot values in the receipt fix the strand ordering
|
||||
3. The bracket parameters (kappa, phi) fix the PhaseVec
|
||||
4. The residual series ε_seq fixes the convergence trajectory
|
||||
5. Structural tokens fix scar status
|
||||
6. Any two states producing the same DP-RRC receipt must agree on all 6 dimensions → they are equal
|
||||
|
||||

|
||||
|
||||
## 6. Concrete Corpus278 Example
|
||||

|
||||

||||
"status": "candidate",
|
||||
"alignment_score": 100,
|
||||
"promotion": "not_promoted"
|
||||
}
|
||||
```
|
||||
|
||||
Equivalent DP-RRC form:
|

||||
|
||||
## 7. Why DP-RRC for Sidon Collision and Compression
|
||||
|
||||
### 7.1 Dot-Depth = Sidon Label (Direct)
|
||||
|
||||
The dot-count hierarchy **is** the Sidon address space:
|
||||
|
||||
```
|
||||
d=0 → label 1 → strand 0
|
||||
d=1 → label 2 → strand 1
|
||||
d=2 → label 4 → strand 2
|
||||
d=3 → label 8 → strand 3
|
||||
d=4 → label 16 → strand 4
|
||||
d=5 → label 32 → strand 5
|
||||
d=6 → label 64 → strand 6
|
||||
d=7 → label 128 → strand 7
|
||||
```
|
||||
|
||||
A DP-Expr parser for RRC can compute Sidon slack on the fly:
|
||||
```python
|
||||
slack = 128 - (1 << max_depth_seen)
|
||||
```
|
||||
|
||||
### 7.2 Collision Detection via Depth Mismatch
|
||||
|
||||
A **collision** occurs when two tokens with the same dot-count appear where one is expected:
|
||||
```
|
||||
.a ..b ..c ; valid — siblings
|
||||
.a ..b ..b ; collision — duplicate depth-2 token
|
||||
```
|
||||
|
||||
This maps to Sidon collision: two strands attempt the same label. The pairwise-sum uniqueness of Sidon sets means a collision is immediately detectable as a depth violation.
|
||||
|
||||
### 7.3 Compression via Depth Run-Length
|
||||
|
||||
Consecutive tokens at the same depth can be run-length encoded:
|
||||
```
|
||||
; Before (13 tokens):
|
||||
.0 .1 .2 .3 .4 .5 .6
|
||||
; After (2 tokens + count):
|
||||
.0 ..7
|
||||
```
|
||||
|
||||
This compresses the convergence trajectory ε_seq: a run of `k` steps with identical residual magnitude collapses to `depth + count`.
|
||||
|
||||
### 7.4 Scar Absence as Structural Token
|
||||
|
||||
Most receipts will have `scar_absent = true`. Encoding this as a structural token (`.`) rather than a boolean field (`"scar_absent": true`) saves bytes and, more importantly, makes the encoding homomorphic with the state: **an empty slot in the receipt corresponds to an empty slot in the braid state**.
|
||||
|
||||
---
|
||||
|
||||
## 8. Implementation Path
|
||||
|
||||
### 8.1 Parser/Translator (Python shim)
|
||||
|
||||
A lightweight Python translator `4-Infrastructure/shim/dp_rrc_translate.py`:
|
||||
|
||||
```python
|
||||
def parse_dp_expr(text):
|
||||
"""DP-Expr → nested list (S-Expr form)."""
|
||||
tokens = text.strip().split()
|
||||
stack = [[]]
|
||||
current_depth = 0
|
||||
for tok in tokens:
|
||||
depth = len(tok) - len(tok.lstrip('.'))
|
||||
val = tok[depth:]
|
||||
while depth > current_depth:
|
||||
stack.append([])
|
||||
current_depth += 1
|
||||
while depth < current_depth:
|
||||
closed = stack.pop()
|
||||
stack[-1].append(closed)
|
||||
current_depth -= 1
|
||||
stack[-1].append(val)
|
||||
while len(stack) > 1:
|
||||
stack[-2].append(stack.pop())
|
||||
return stack[0]
|
||||
|
||||
def emit_dp_expr(sexpr, depth=0):
|
||||
"""S-Expr → DP-Expr string."""
|
||||
if not isinstance(sexpr, list):
|
||||
return '.' * depth + str(sexpr)
|
||||
lines = []
|
||||
for item in sexpr:
|
||||
lines.append(emit_dp_expr(item, depth + 1))
|
||||
return '\n'.join(lines)
|
||||
```
|
||||
|
||||
### 8.2 Lean Theorem
|
||||
|
||||
A new theorem in `BraidEigensolid.lean`:
|
||||
|
||||
```lean
|
||||
theorem dp_receipt_invertible (r : BraidReceipt) (s s' : BraidState) :
|
||||
encodeReceiptDP r = encodeReceiptDP r' → r.depthEncoding = r'.depthEncoding → s = s' :=
|
||||
by
|
||||
-- dot-depth uniquely determines Sidon label assignment
|
||||
-- structural tokens uniquely determine scar status
|
||||
-- therefore receipt is invertible
|
||||
```
|
||||
|
||||
### 8.3 Integration into AVMIsa.Emit
|
||||
|
||||
Add a `dp_rrc_corpus278_v1` schema alongside the existing `avm_rrc_corpus278_v1`. The AVM canary check is the same; only the output format changes. The DP-Expr form can be emitted as a `#eval` string in the existing JSON bundle under a `"dp_expr"` key.
|
||||
|
||||

|
||||
|
||||
## 9. Summary
|
||||
|
||||
| Aspect | Current RRC | DP-RRC Proposed |
|
||||
|--------|-------------|-----------------|
|
||||
| Receipt encoding | JSON objects with explicit field names | Dot-prefixed depth markers |
|
||||
| Sidon labels | Slots stored as integers `[1,2,4,8,16,32,64,128]` | Implicit from dot-depth `2^d` |
|
||||
| Scar absence | `"scar_absent": true` boolean | Structural token `.` — no value emitted |
|
||||
| Convergence | `residuals` as JSON array | Run-length encoded depth stream |
|
||||
| Nesting | Explicit JSON `{}` nesting | Implicit depth coordinate walk |
|
||||
| Round-trip | `receipt_invertible` theorem | Dot-count + structural token invertibility |
|
||||
| Corpus format | 250-row flat JSON | Hierarchical DP-Expr with row bundling |
|
||||
|
||||
The DP-Expr encoding does not replace the existing JSON format — both are interchangeable. It provides a compact, depth-native representation that makes the Sidon label assignment explicit in the syntax itself, which is the key insight for collision detection and compression path analysis.
