Executive Summary + +This ADR documents the findings of a comprehensive architectural review of the ruvector ecosystem as it relates to EXO-AI and proposes a unified multi-paradigm integration architecture that wires together six distinct computational substrates: + +1. **Classical vector cognition** — HNSW, attention, GNN (`ruvector-core`, `ruvector-attention`, `ruvector-gnn`) +2. **Quantum execution intelligence** — circuit simulation, coherence gating, exotic search (`ruQu`, `ruqu-exotic`) +3. **Biomolecular computing** — genomic analysis, DNA strand similarity, pharmacogenomics (`examples/dna`, `ruvector-solver`) +4. **Neuromorphic cognition** — spiking networks, HDC, BTSP, circadian routing (`ruvector-nervous-system`, `meta-cognition-spiking-neural-network`) +5. **Consciousness substrate** — IIT Φ, Free Energy, TDA, Strange Loops (`examples/exo-ai-2025`) +6. **Universal coherence spine** — sheaf Laplacian gating, formal proofs, adaptive learning (`prime-radiant`, `ruvector-verified`, `sona`) + +**Critical finding**: Across 100+ crates and 830K+ lines of Rust code, the same mathematical primitives have been independently implemented three or more times without cross-wiring. This document identifies 7 convergent evolution clusters and proposes a canonical integration architecture that eliminates duplication while enabling capabilities that are currently impossible because the components do not speak to each other. + +**Honest assessment of what works today vs. what requires integration work**: see Section 4. + +--- + +## 2. Context + +### 2.1 EXO-AI 2025 Architecture + +`examples/exo-ai-2025` is a 9-crate, ~15,800-line consciousness research platform built on rigorous theoretical foundations: + +| Crate | Role | Key Theory | +|-------|------|-----------| +| `exo-core` | IIT Φ computation, Landauer thermodynamics | Tononi IIT 4.0 | +| `exo-temporal` | Causal memory, light-cone queries, anticipation | Temporal knowledge graphs, causal inference | +| `exo-hypergraph` | Persistent homology, sheaf consistency, Betti numbers | TDA, Grothendieck sheaf theory | +| `exo-manifold` | SIREN networks, gradient-descent retrieval, strategic forgetting | Manifold learning | +| `exo-exotic` | 10 cognitive experiments (Dreams, Free Energy, Morphogenesis, Collective Φ, etc.) | Friston, Hofstadter, Hoel, Eagleman, Turing | +| `exo-federation` | Byzantine PBFT, CRDT reconciliation, post-quantum Kyber | Distributed systems | +| `exo-backend-classical` | SIMD backend (8–54× speedup) | ruvector-core integration | +| `exo-wasm` | Browser/edge deployment | WASM, 2 MB binary | +| `exo-node` | Node.js NAPI bindings | napi-rs | + +EXO-AI has 11 explicitly listed research frontiers that are currently unimplemented stubs: +`01-neuromorphic-spiking`, `02-quantum-superposition`, `03-time-crystal-cognition`, +`04-sparse-persistent-homology`, `05-memory-mapped-neural-fields`, +`06-federated-collective-phi`, `07-causal-emergence`, `08-meta-simulation-consciousness`, +`09-hyperbolic-attention`, `10-thermodynamic-learning`, `11-conscious-language-interface` + +**Key insight**: Every one of these research frontiers already has a working implementation elsewhere in the ruvector ecosystem.

Problem Statement: Convergent Evolution Without Integration + +### 3.1 The Seven Duplication Clusters + +The following primitives have been independently implemented multiple times: + +#### Cluster 1: Elastic Weight Consolidation (EWC / Catastrophic Forgetting Prevention) +| Implementation | Location | Variant | +|----------------|----------|---------| +| EWC | `ruvector-gnn/src/` | Standard Fisher Information regularization | +| EWC++ | `crates/sona/` | Enhanced with bidirectional plasticity | +| EWC | `ruvector-nervous-system/` | Integrated with BTSP and E-prop | +| MicroLoRA + EWC++ | `ruvector-learning-wasm/` | <100µs WASM adaptation | + +**Impact**: Four diverging implementations with no shared API. Cross-crate forgetting prevention impossible. + +#### Cluster 2: Coherence Gating (The Universal Safety Primitive) +| Implementation | Location | Mechanism | +|----------------|----------|-----------| +| ruQu coherence gate | `crates/ruQu/` | Dynamic min-cut (O(nᵒ⁽¹⁾)), PERMIT/DEFER/DENY | +| Prime-Radiant | `crates/prime-radiant/` | Sheaf Laplacian energy, 4-tier compute ladder | +| Nervous system circadian | `ruvector-nervous-system/` | Kuramoto oscillators, 40Hz gamma, duty cycling | +| λ-gated transformer | `ruvector-mincut-gated-transformer/` | Min-cut value as coherence signal | +| Cognitum Gate | `cognitum-gate-kernel/`, `cognitum-gate-tilezero/` | 256-tile fabric, e-value sequential testing | + +**Impact**: Five independent safety systems that cannot compose. An agent crossing subsystem boundaries has no coherent safety guarantees. + +#### Cluster 3: Cryptographic Witness Chains (Audit & Proof) +| Implementation | Location | Primitive | +|----------------|----------|-----------| +| PermitToken + WitnessReceipt | `crates/ruQu/` | Ed25519 | +| Witness chain | `prime-radiant/` | Blake3 hash-linked | +| ProofAttestation | `ruvector-verified/` | lean-agentic dependent types, 82-byte | +| RVF witness | `crates/rvf/rvf-crypto/` | SHAKE-256 chain + ML-DSA-65 | +| Container witness | `ruvector-cognitive-container/` | Hash-linked ContainerWitnessReceipt | +| TileZero receipts | `cognitum-gate-tilezero/` | Ed25519 + Blake3 | + +**Impact**: Six incompatible audit trails. Cross-subsystem proof chains impossible to construct. + +#### Cluster 4: Sheaf Theory (Local-to-Global Consistency) +| Implementation | Location | Application | +|----------------|----------|-------------| +| Sheaf Laplacian | `prime-radiant/` | Universal coherence energy E(S) = Σ wₑ·‖ρᵤ-ρᵥ‖² | +| Sheaf consistency | `exo-hypergraph/` | Local section agreement, restriction maps | +| Manifold sheaf | `ruvector-graph-transformer/` | Product geometry S⁶⁴×H³²×ℝ³² | + +**Impact**: Prime-Radiant's sheaf engine and EXO-AI's sheaf hypergraph implement the same mathematics with no shared data structures. + +#### Cluster 5: Spike-Driven Computation +| Implementation | Location | Energy Reduction | +|----------------|----------|-----------------| +| Biological module | `ruvector-graph-transformer/` | 87.2× vs dense attention | +| Spiking nervous system | `ruvector-nervous-system/` | Event-driven, K-WTA <1µs | +| Meta-cognition SNN | `examples/meta-cognition-spiking-neural-network/` | LIF+STDP, 18.4× speedup | +| Spike-driven scheduling | `ruvector-mincut-gated-transformer/` | Tier 3 skip: 50-200× speedup | + +**Impact**: EXO-AI's `01-neuromorphic-spiking` research frontier is listed as unimplemented. Three working implementations exist elsewhere. + +#### Cluster 6: Byzantine Fault-Tolerant Consensus +| Implementation | Location | Protocol | +|----------------|----------|---------| +| exo-federation | `exo-ai-2025/exo-federation/` | PBFT (O(n²) messages) | +| ruvector-raft | `crates/ruvector-raft/` | Raft (leader election, log replication) | +| delta-consensus | `ruvector-delta-consensus/` | CRDT + causal ordering | +| Cognitum 256-tile | `cognitum-gate-kernel/` | Anytime-valid, e-value testing | + +**Impact**: EXO-AI's federation layer re-implements consensus that `ruvector-raft` + `cognitum-gate` already provide with stronger formal guarantees. + +#### Cluster 7: Free Energy / Variational Inference +| Implementation | Location | Algorithm | +|----------------|----------|-----------| +| Friston FEP experiment | `exo-exotic/` | KL divergence: F = D_KL[q(θ\|o)‖p(θ)] - ln p(o) | +| Information Bottleneck | `ruvector-attention/` | VIB: KL divergence (Gaussian/Categorical/Jensen-Shannon) | +| CG/Neumann solvers | `ruvector-solver/` | Sparse linear systems for gradient steps | +| BMSSP multigrid | `ruvector-solver/` | Laplacian systems (free energy landscape) | + +**Impact**: EXO-AI's free energy minimization uses manual gradient descent. The solver crate already has conjugate gradient and multigrid solvers that are 10–80× faster for the underlying sparse linear problems. + +--- + +## 4.

The canonical format is the `RvfWitnessReceipt` (SHAKE-256 + ML-DSA-65) with subsystem-specific extension fields: + +```rust +/// Unified cross-subsystem witness — all subsystems emit this +pub struct CrossParadigmWitness { + /// RVF base receipt (SHAKE-256 chain link) + pub base: RvfWitnessSegment, + /// Formal proof from ruvector-verified (82 bytes, lean-agentic) + pub proof_attestation: Option, + /// Quantum gate decision from ruQu (Ed25519 PermitToken or deny) + pub quantum_gate: Option, + /// Prime-Radiant sheaf energy at decision point + pub sheaf_energy: Option, + /// Cognitum tile decision (PERMIT/DEFER/DENY + e-value) + pub tile_decision: Option, + /// IIT Φ at decision substrate (from exo-core) + pub phi_value: Option, + /// Genomic context if relevant (`.rvdna` segment hash) + pub genomic_context: Option<[u8; 32]>, +} +``` + +**Decision**: The RVF witness chain (SHAKE-256 + ML-DSA-65) is the canonical root. All other witness formats are embedded as optional extension fields. This preserves backward compatibility while enabling cross-paradigm proof chains. + +### 5.3 The Canonical Coherence Gate + +Replace the five independent coherence gating implementations with a single `CoherenceRouter` that delegates to the appropriate backend: + +```rust +pub struct CoherenceRouter { + /// Prime-Radiant sheaf Laplacian engine (primary — mathematical) + prime_radiant: Arc, + /// ruQu coherence gate (quantum substrates) + quantum_gate: Option>, + /// Cognitum 256-tile fabric (distributed AI agents) + cognitum: Option>, + /// Nervous system circadian (bio-inspired, edge deployment) + circadian: Option>, +} + +pub enum CoherenceBackend { + /// Mathematical proof of consistency — use for safety-critical paths + SheafLaplacian, + /// Sub-millisecond quantum circuit gating + Quantum, + /// 256-tile distributed decision fabric + Distributed, + /// Energy-efficient bio-inspired gating (edge/WASM) + Circadian, + /// Composite: all backends must agree (highest confidence) + Unanimous, +} + +impl CoherenceRouter { + pub async fn gate( + &self, + action: &ActionContext, + backend: CoherenceBackend, + ) -> Result; +} +``` + +**Decision**: `prime-radiant` is the canonical mathematical backbone for all coherence decisions on CPU-bound paths. `cognitum-gate` handles distributed multi-agent contexts. `ruQu` handles quantum substrates. `CircadianController` handles edge/battery-constrained deployments. + +### 5.4 The Canonical Plasticity System + +Replace four independent EWC implementations with a single `PlasticityEngine`: + +```rust +pub struct PlasticityEngine { + /// SONA MicroLoRA: <1ms instant adaptation + instant: Arc, + /// EWC++ Fisher Information regularization (shared) + ewc: Arc, + /// BTSP behavioral timescale (1-3 second windows, from nervous-system) + btsp: Option>, + /// E-prop eligibility propagation (1000ms credit assignment) + eprop: Option>, + /// ReasoningBank pattern library (SONA) + reasoning_bank: Arc, +} +``` + +**Decision**: SONA's EWC++ is the production implementation. `ruvector-nervous-system`'s BTSP and E-prop add biological plasticity modes not in SONA. `ruvector-gnn`'s EWC is deprecated in favor of this shared engine. + +### 5.5 The Canonical Free Energy Solver + +EXO-AI's Friston free energy experiment currently uses naive gradient descent. Replace with the solver crate: + +```rust +/// Bridge: Free Energy minimization via sparse linear solver +/// F = D_KL[q(θ|o) || p(θ)] - ln p(o) +/// Gradient: ∇F = F^{-1}(θ) · ∇ log p(o|θ) [Natural gradient via Fisher Info] +pub fn minimize_free_energy_cg( + model: &mut PredictiveModel, + observation: &[f64], + budget: &ComputeBudget, +) -> Result { + // Build Fisher Information Matrix as sparse CSR + let fim = build_sparse_fisher_information(model); + // Gradient of log-likelihood + let grad = compute_log_likelihood_gradient(model, observation); + // Conjugate gradient solve: F^{-1} * grad (natural gradient step) + let cg_solver = ConjugateGradientSolver::new(budget); + cg_solver.solve(&fim, &grad, budget) +} +``` + +**Expected speedup**: 10–80× vs. current manual gradient descent, based on solver benchmarks. + +--- + +## 6. Component Integration Contracts + +### 6.1 ruQu Exotic → EXO-AI Pattern Storage + +**Interface**: `ruqu-exotic` emits `QuantumSearchResult` containing amplitude-weighted candidates. EXO-AI's `Pattern` type receives these as pre-scored candidates with `salience` derived from `|amplitude|²`. + +```rust +/// Implemented in: crates/ruqu-exotic/src/interference_search.rs +pub struct QuantumSearchResult { + pub candidates: Vec<(PatternId, Complex64)>, // (id, amplitude) + pub collapsed_top_k: Vec<(PatternId, f32)>, // post-measurement scores + pub coherence_metric: f64, +} + +/// Integration: exo-temporal receives quantum-filtered results +impl TemporalMemory { + pub fn store_with_quantum_context( + &mut self, + pattern: Pattern, + antecedents: &[PatternId], + quantum_context: Option, + ) -> Result; +} +``` + +**Quantum decay integration**: `ruqu-exotic::quantum_decay` replaces EXO-AI's current TTL-based eviction. Embeddings decohere with T₁/T₂ time constants instead of hard deletion. This enables EXO-AI's `02-quantum-superposition` research frontier. + +### 6.2 ruvector-nervous-system → EXO-AI Neuromorphic Backend + +**Interface**: Expose `NervousSystemBackend` as an implementation of EXO-AI's `SubstrateBackend` trait: + +```rust +pub struct NervousSystemBackend { + reflex_layer: ReflexLayer, // K-WTA <1µs decisions + memory_layer: MemoryLayer, // HDC 10,000-bit hypervectors + Hopfield + learning_layer: LearningLayer, // BTSP one-shot + E-prop + EWC + coherence_layer: CoherenceLayer, // Kuramoto 40Hz + global workspace +} + +impl SubstrateBackend for NervousSystemBackend { + fn similarity_search(&self, query: &[f32], k: usize, filter: Option<&Filter>) + -> Result> { + // Route: reflex (K-WTA) → memory (HDC/Hopfield) → learning + self.reflex_layer.k_wta_search(query, k) + } + + fn manifold_deform(&self, pattern: &Pattern, lr: f32) + -> Result { + // BTSP one-shot learning (1-3 second window) + self.learning_layer.btsp_update(pattern, lr) + } +} +``` + +**Enables**: EXO-AI `01-neuromorphic-spiking` (BTSP/STDP), `03-time-crystal-cognition` (circadian), `10-thermodynamic-learning` (E-prop eligibility). + +### 6.3 prime-radiant → Replace exo-federation + +**Rationale**: `exo-federation` implements PBFT with O(n²) message complexity and custom Kyber handshake. `prime-radiant` + `cognitum-gate` + `ruvector-raft` provides the same guarantees with: +- Mathematical consistency proofs (sheaf Laplacian) rather than voting +- Anytime-valid decisions with Type I error bounds +- Better scaling (cognitum 256-tile vs. PBFT O(n²)) +- Existing production use in the ecosystem + +**Migration path**: + +```rust +// BEFORE: exo-federation Byzantine PBFT +impl FederatedMesh { + pub async fn byzantine_commit(&self, update: &StateUpdate) -> Result; +} + +// AFTER: prime-radiant + cognitum route +impl FederatedMesh { + pub async fn coherent_commit(&self, update: &StateUpdate) -> Result { + // 1.

Emit unified witness + Ok(CrossParadigmWitness::from(energy, decision, log_entry)) + } +} +``` + +**Preserve**: `exo-federation`'s post-quantum Kyber channel setup and CRDT reconciliation are novel and should be retained.

Alternatives Considered + +### Alternative A: Monolithic EXO-AI Rewrite + +Build all capabilities from scratch inside `examples/exo-ai-2025`. + +**Rejected**: The ecosystem already contains 830K+ lines of working, tested Rust. EXO-AI's 15,800 lines would need to replicate 10× more code. The duplication problem would worsen. + +### Alternative B: Keep Subsystems Isolated + +Do not integrate; let EXO-AI, ruQu, ruDNA, and the SOTA crates develop independently. + +**Rejected**: The convergent evolution of EWC, coherence gating, sheaf theory, and cryptographic witnesses shows the subsystems are solving the same problems differently. Without unification, maintenance cost grows O(n²) with ecosystem size. Cross-paradigm capabilities (quantum-genomic-neuromorphic fusion) are impossible without integration. + +### Alternative C: Build a New "Integration Crate" + +Create `ruvector-multiparadigm` that imports all subsystems and exposes a unified API. + +**Partially adopted**: The `CoherenceRouter`, `PlasticityEngine`, and `CrossParadigmWitness` are effectively this, but implemented as trait + adapter layers rather than a monolithic new crate. This avoids a single large dependency that all other crates must adopt. + +### Alternative D: Replace Prime-Radiant with ruQu as Primary Coherence Gate + +Use ruQu's coherence gate (min-cut, 468ns P99) as the single coherence primitive. + +**Rejected**: ruQu is optimized for quantum substrate health monitoring. Prime-Radiant's sheaf Laplacian provides mathematical proofs applicable to arbitrary domains (AI agents, genomics, financial systems). Both are needed; CoherenceRouter selects based on context. + +--- + +## 13.

Decision + +**Adopted**: Proceed with phased integration as described in Section 10. + +The multi-paradigm fusion architecture is the correct path. The ruvector ecosystem has independently developed world-class implementations of quantum coherence gating, neuromorphic computation, genomic AI, and consciousness theory. These are not competing implementations — they are complementary computational substrates that, when composed, enable a form of machine cognition unavailable in any single paradigm. + +The canonical unification primitives (`CoherenceRouter`, `PlasticityEngine`, `CrossParadigmWitness`) are minimal by design. Each subsystem retains its identity and can be used independently. Integration is additive. + +**The central claim of this ADR**: A system that computes IIT Φ weighted by genomic pharmacogenomics, retrieves via quantum amplitude interference, learns via BTSP one-shot plasticity, corrects reasoning errors via surface-code QEC, and proves consistency via sheaf Laplacian mathematics does not exist anywhere in the AI research landscape. It can be built now from components that are already working. + +--- + +## Appendix A: Crate Dependency Graph (Integration Architecture) + +``` +exo-ai-2025 (consciousness substrate) +├── ruvector-core (HNSW, embeddings) +├── ruvector-nervous-system [NEW] (neuromorphic backend) +├── ruqu-exotic [NEW] (quantum search, decay, QEC) +├── prime-radiant [NEW, replaces exo-federation consensus] +├── cognitum-gate-kernel + tilezero [NEW, replaces exo-federation PBFT] +├── ruvector-raft [NEW, replaces exo-federation PBFT] +├── ruvector-verified [NEW] (formal proofs for Φ computation) +├── sona [NEW] (learning system) +├── ruvector-graph-transformer [NEW] (manifold + temporal + biological modules) +├── ruvector-solver [NEW] (free energy CG, morphogenesis BMSSP, sparse TDA) +├── ruvllm + mcp-gate [NEW] (language interface + action gating) +└── examples/dna [NEW] (genomic pattern source via .rvdna conversion) + +Preserved as-is: +├── exo-core (IIT Φ engine) +├── exo-temporal (causal memory) +├── exo-hypergraph (persistent homology) +├── exo-manifold (SIREN networks) +├── exo-exotic (10 cognitive experiments) +├── exo-backend-classical (SIMD backend) +├── exo-wasm (browser deployment) +└── exo-node (Node.js bindings) +``` + +## Appendix B: Key Research References + +| Algorithm | Paper | Year | Used In | +|-----------|-------|------|---------| +| Dynamic Min-Cut Subpolynomial | El-Hayek, Henzinger, Li (arXiv:2512.13105) | Dec 2025 | ruQu, ruvector-mincut, subpolynomial-time example | +| IIT 4.0 | Tononi, Koch | 2023 | exo-core consciousness.rs | +| Free Energy Principle | Friston | 2010+ | exo-exotic free_energy.rs | +| Surface Code QEC | Google Quantum AI (Nature) | 2024 | ruqu-algorithms surface_code.rs | +| BTSP (Behavioral Timescale Plasticity) | Bittner et al. | 2017 | ruvector-nervous-system | +| E-prop | Bellec et al. | 2020 | ruvector-nervous-system | +| BitNet b1.58 | Ma et al. | 2024 | ruvllm | +| Flash Attention 2 | Dao | 2023 | ruvector-attention, ruvllm | +| Sheaf Laplacian | Hansen, Ghrist | 2021 | prime-radiant | +| Persistent Homology | Edelsbrunner, Harer | 2010 | exo-hypergraph | +| CRYSTALS-Kyber | NIST FIPS 203 | 2024 | exo-federation | +| ML-DSA-65 | NIST FIPS 204 | 2024 | rvf-crypto | +| Causal Emergence | Hoel et al. | 2013 | exo-exotic emergence.rs | +| Strange Loops | Hofstadter | 1979 | exo-exotic strange_loop.rs | +| Landauer's Principle | Landauer | 1961 | exo-core thermodynamics.rs | +| Turing Morphogenesis | Turing | 1952 | exo-exotic morphogenesis.rs | +| Hyperdimensional Computing | Kanerva | 2009 | ruvector-nervous-system | +| Modern Hopfield Networks | Ramsauer et al. | 2021 | ruvector-nervous-system | +| HNSW | Malkov, Yashunin (TPAMI) | 2018 | ruvector-core | +| VQE | Peruzzo et al. | 2014 | ruqu-algorithms | +| QAOA | Farhi, Goldstone, Gutmann | 2014 | ruqu-algorithms | +| Grover Search | Grover | 1996 | ruqu-algorithms | +| Horvath Epigenetic Clock | Horvath | 2013 | examples/dna epigenomics.rs | +| Smith-Waterman | Smith, Waterman | 1981 | examples/dna alignment.rs | +| Forward Push PPR | Andersen, Chung, Lang (FOCS) | 2006 | ruvector-solver | From 4061e1b1c7defef1e47a79fa5ef54f352cd3c917 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 27 Feb 2026 03:04:07 +0000 Subject: [PATCH 02/18] =?UTF-8?q?feat(exo-core):=20ADR-029=20Phase=201=20c?= =?UTF-8?q?anonical=20primitives=20=E2=80=94=20CoherenceRouter,=20Plastici?= =?UTF-8?q?tyEngine,=20CrossParadigmWitness?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - CoherenceRouter: π-scaled spectral gap estimation, 5 backend variants - PlasticityEngine: unified EWC++, BTSP, E-prop with Φ-weighted protection - CrossParadigmWitness: hash-chained audit type for multi-paradigm stack - All tests passing, gate latency <1ms confirmed https://claude.ai/code/session_019Lt11HYsW1265X7jB7haoC --- .../crates/exo-core/src/coherence_router.rs | 330 ++++++++++++++++++ .../exo-ai-2025/crates/exo-core/src/lib.rs | 8 + .../crates/exo-core/src/plasticity_engine.rs | 306 ++++++++++++++++ .../crates/exo-core/src/witness.rs | 208 +++++++++++ 4 files changed, 852 insertions(+) create mode 100644 examples/exo-ai-2025/crates/exo-core/src/coherence_router.rs create mode 100644 examples/exo-ai-2025/crates/exo-core/src/plasticity_engine.rs create mode 100644 examples/exo-ai-2025/crates/exo-core/src/witness.rs diff --git a/examples/exo-ai-2025/crates/exo-core/src/coherence_router.rs b/examples/exo-ai-2025/crates/exo-core/src/coherence_router.rs new file mode 100644 index 000000000..d07e55cda --- /dev/null +++ b/examples/exo-ai-2025/crates/exo-core/src/coherence_router.rs @@ -0,0 +1,330 @@ +//!

charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 2 — exo-manifold/src/transfer_store.rs TransferManifold stores (src, dst) transfer priors as 64-dim deformable patterns via ManifoldEngine::deform. Sinusoidal domain-ID hashing gives meaningful cosine distances for retrieve_similar. Phase 3 — exo-temporal/src/transfer_timeline.rs TransferTimeline records transfer events in the temporal causal graph. Each event is linked to its predecessor so the system can trace full transfer trajectories. anticipate_next() returns CausalChain + SequentialPattern hints. Phase 4 — exo-federation/src/transfer_crdt.rs TransferCrdt propagates transfer priors across the federation using LWW-Map (cycle = timestamp) + G-Set for domain discovery. Merges are idempotent and commutative. promote_via_consensus runs PBFT Byzantine commit before accepting a prior. Phase 5 — exo-exotic/src/domain_transfer.rs StrangeLoopDomain implements the Domain trait: self-referential tasks whose solutions are scored by meta-cognitive keyword density. CollectiveDomainTransfer couples CollectiveConsciousness with DomainExpansionEngine — arm rewards flow into the substrate and collective Φ serves as the cycle quality metric. EmergentTransferDetector wraps EmergenceDetector to surface non-linear capability gains from cross-domain transfer. All 4 crates gain the ruvector-domain-expansion path dep. 36 new tests, all green alongside the existing suite. https://claude.ai/code/session_019Lt11HYsW1265X7jB7haoC --- examples/exo-ai-2025/Cargo.lock | 4 + .../exo-ai-2025/crates/exo-exotic/Cargo.toml | 1 + .../crates/exo-exotic/src/domain_transfer.rs | 343 ++++++++++++++++++ .../exo-ai-2025/crates/exo-exotic/src/lib.rs | 1 + .../crates/exo-federation/Cargo.toml | 1 + .../crates/exo-federation/src/lib.rs | 5 +- .../exo-federation/src/transfer_crdt.rs | 222 ++++++++++++ .../crates/exo-manifold/Cargo.toml | 1 + .../crates/exo-manifold/src/lib.rs | 1 + .../crates/exo-manifold/src/transfer_store.rs | 202 +++++++++++ .../crates/exo-temporal/Cargo.toml | 1 + .../crates/exo-temporal/src/lib.rs | 1 + .../exo-temporal/src/transfer_timeline.rs | 196 ++++++++++ 13 files changed, 977 insertions(+), 2 deletions(-) create mode 100644 examples/exo-ai-2025/crates/exo-exotic/src/domain_transfer.rs create mode 100644 examples/exo-ai-2025/crates/exo-federation/src/transfer_crdt.rs create mode 100644 examples/exo-ai-2025/crates/exo-manifold/src/transfer_store.rs create mode 100644 examples/exo-ai-2025/crates/exo-temporal/src/transfer_timeline.rs diff --git a/examples/exo-ai-2025/Cargo.lock b/examples/exo-ai-2025/Cargo.lock index e2efea588..aea7df801 100644 --- a/examples/exo-ai-2025/Cargo.lock +++ b/examples/exo-ai-2025/Cargo.lock @@ -781,6 +781,7 @@ dependencies = [ "petgraph", "rand 0.8.5", "rayon", + "ruvector-domain-expansion", "serde", "serde_json", "thiserror 1.0.69", @@ -800,6 +801,7 @@ dependencies = [ "pqcrypto-kyber", "pqcrypto-traits", "rand 0.8.5", + "ruvector-domain-expansion", "serde", "serde_json", "sha2", @@ -856,6 +858,7 @@ dependencies = [ "exo-core 0.1.0 (registry+https://github.com/rust-lang/crates.io-index)", "ndarray", "parking_lot", + "ruvector-domain-expansion", "serde", "thiserror 1.0.69", ] @@ -887,6 +890,7 @@ dependencies = [ "exo-core 0.1.0 (registry+https://github.com/rust-lang/crates.io-index)", "parking_lot", "petgraph", + "ruvector-domain-expansion", "serde", "thiserror 2.0.17", "tokio", diff --git a/examples/exo-ai-2025/crates/exo-exotic/Cargo.toml b/examples/exo-ai-2025/crates/exo-exotic/Cargo.toml index ad8362d00..acabfa236 100644 --- a/examples/exo-ai-2025/crates/exo-exotic/Cargo.toml +++ b/examples/exo-ai-2025/crates/exo-exotic/Cargo.toml @@ -15,6 +15,7 @@ readme = "README.md" [dependencies] exo-core = { path = "../exo-core" } exo-temporal = "0.1" +ruvector-domain-expansion = { path = "../../../../crates/ruvector-domain-expansion" } # Serialization serde = { version = "1.0", features = ["derive"] } diff --git a/examples/exo-ai-2025/crates/exo-exotic/src/domain_transfer.rs b/examples/exo-ai-2025/crates/exo-exotic/src/domain_transfer.rs new file mode 100644 index 000000000..2eb77a34c --- /dev/null +++ b/examples/exo-ai-2025/crates/exo-exotic/src/domain_transfer.rs @@ -0,0 +1,343 @@ +//!
