Target: 10-20x speedup to sub-100us proofs | + +--- + +## 1. Executive Summary + +This ADR proposes integrating the [`lean-agentic`](https://crates.io/crates/lean-agentic) crate (v0.1.0, Apache-2.0) into the RuVector workspace. Lean-Agentic provides a hash-consed dependent type theory kernel with 150x faster equality checking (0.3ns term comparison), formal verification primitives, and an AI optimization layer including JIT compilation, multi-lane LLM routing, and AgentDB vector memory. Integration gives RuVector proof-carrying vectors, formally verified pipeline invariants, and a compile-time safety layer for critical paths like genomic analysis, financial computation, and cognitive containers. + +**Decision**: Add `lean-agentic = "=0.1.0"` as a pinned workspace dependency, creating a new `ruvector-verified` bridge crate (independent versioning at `0.1.0`, initially `publish = false`) that maps RuVector primitives to lean-agentic's type system. All verification is feature-gated — zero impact on existing builds. + +**License note**: lean-agentic is Apache-2.0; the RuVector workspace is MIT. These are compatible (Apache-2.0 can be consumed by MIT projects). The new `ruvector-verified` crate will use `MIT OR Apache-2.0` dual licensing to align with both. + +--- + +## 2.

For `no_std` builds, the arena would need a `hashbrown` replacement -- this is a Phase 4 concern. + +--- + +## 3. Integration Rationale + +### 3.1 Why Lean-Agentic for RuVector + +RuVector's crate ecosystem handles high-stakes computation: genomic analysis, financial risk, graph neural networks, quantum simulation. These domains demand **correctness guarantees** beyond what unit tests alone provide. + +Lean-Agentic provides: + +1. **Proof-Carrying Vectors** -- Attach type-theoretic proofs to HNSW index operations, certifying dimensionality, distance metric correctness, and recall bounds. + +2. **Verified Pipeline Invariants** -- Use dependent types to encode that DNA pipeline stages (ADR-001 through ADR-015) preserve data integrity across transformations. + +3. **Formal Safety for Cognitive Containers** -- RVF containers (ADR-029/030) can carry machine-checked proofs of their behavioral contracts, chaining into the existing WITNESS_SEG format. + +4. **Zero-Cost at Runtime** -- Compile-time proof erasure means zero overhead in release builds. Only the 0.3ns equality check remains for runtime assertions. + +5. **Shared Toolchain** -- Same maintainer, same org, Rust-native. No FFI boundaries or language impedance. + +### 3.2 RuVector Integration Points + +| RuVector Crate | Integration | Lean-Agentic Module | Phase | +|---------------|-------------|---------------------|-------| +| `ruvector-core` (HNSW) | Proven dimensionality/metric invariants | `typechecker`, `term` | 2 | +| `ruvector-attention` | Verified attention mask shapes | `typechecker`, `conversion` | 4 | +| `ruvector-solver` | Proven convergence properties | `unification`, `environment` | 4 | +| `ruvector-coherence` | Formal sheaf consistency proofs | `typechecker`, `level` | 4 | +| `ruvector-gnn` | Verified graph topology invariants | `term`, `arena` | 4 | +| `ruvector-delta-consensus` | Proven CRDT merge commutativity | `conversion`, `unification` | 4 | +| `prime-radiant` | Formal categorical coherence | `level`, `typechecker` | 4 | +| `cognitum-gate-kernel` | Verified gate predicates | `typechecker`, `environment` | 4 | +| `ruvector-temporal-tensor` | Proven temporal ordering invariants | `term`, `conversion` | 4 | +| `ruvector-cognitive-container` | Proof-carrying cognitive containers via `WitnessChain` | Full kernel | 3 | +| DNA pipeline (`examples/dna`) | Verified genomic transformation chain | Full kernel | 3 | + +**Interop note for `ruvector-coherence`**: The coherence crate currently has a `spectral` feature flag and depends only on `serde`/`serde_json`. Sheaf consistency proofs will live in `ruvector-verified` (not in `ruvector-coherence`) to avoid adding lean-agentic as a dependency to the coherence crate. `ruvector-verified` will import `ruvector-coherence` types and wrap them. + +**Interop note for `ruvector-cognitive-container`**: This crate already exports `WitnessChain`, `CoherenceDecision`, and `ContainerWitnessReceipt`. `ruvector-verified` will produce `ProofAttestation` values that serialize into `WitnessChain` entries -- no parallel types, just a producer-consumer relationship. + +--- + +## 4. Design + +### 4.1 Workspace Changes + +#### Diff to `/workspaces/ruvector/Cargo.toml` + +Add to `[workspace.members]` (after `ruvector-cognitive-container`): + +```toml + "crates/ruvector-verified", +``` + +Add to `[workspace.dependencies]`: + +```toml +# Formal verification +lean-agentic = "=0.1.0" +``` + +Note: `optional = true` is NOT valid in `[workspace.dependencies]`. Optionality is declared in each consuming crate's `[dependencies]` section via `optional = true`. + +This adds one entry to `Cargo.lock` (lean-agentic itself, which has zero transitive deps without the `serde` feature). + +#### Version Strategy + +`ruvector-verified` uses **independent versioning** at `0.1.0`, not `version.workspace = true` (which would give it `2.0.4`). Rationale: this is an experimental bridge crate; it should not inherit the mature workspace version until it reaches feature parity with other `2.x` crates. + +### 4.2 New Crate: `ruvector-verified` + +``` +crates/ + ruvector-verified/ + Cargo.toml + src/ + lib.rs # Public API, re-exports, ProofEnvironment + error.rs # VerificationError enum + vector_types.rs # Dependent types for vector operations + proof_store.rs # Ed25519-signed proof attestation + pipeline.rs # Verified pipeline composition + invariants.rs # Pre-built invariant library + benches/ + proof_generation.rs # Criterion benchmarks + arena_throughput.rs +``` + +#### `Cargo.toml` + +```toml +[package] +name = "ruvector-verified" +version = "0.1.0" +edition = "2021" +rust-version = "1.77" +license = "MIT OR Apache-2.0" +description = "Formal verification layer for RuVector using lean-agentic dependent types" +publish = false # Until Phase 2 complete + +[dependencies] +# Core verification kernel (always required -- this crate IS the verification layer) +lean-agentic = { workspace = true } +thiserror = { workspace = true } + +# Optional integrations with RuVector crates +ruvector-core = { path = "../ruvector-core", optional = true, default-features = false } +ruvector-coherence = { path = "../ruvector-coherence", optional = true } +ruvector-cognitive-container = { path = "../ruvector-cognitive-container", optional = true } +rvf-types = { path = "../rvf/rvf-types", optional = true } +rvf-crypto = { path = "../rvf/rvf-crypto", optional = true, features = ["ed25519"] } + +# Serialization (for proof persistence) +serde = { workspace = true, optional = true } +serde_json = { workspace = true, optional = true } + +[dev-dependencies] +criterion = { workspace = true } +proptest = { workspace = true } + +[features] +default = [] +hnsw-proofs = ["dep:ruvector-core", "ruvector-core/hnsw"] +rvf-proofs = ["dep:rvf-types", "dep:rvf-crypto", "dep:ruvector-cognitive-container"] +coherence-proofs = ["dep:ruvector-coherence"] +serde = ["dep:serde", "dep:serde_json", "lean-agentic/serde"] +all-proofs = ["hnsw-proofs", "rvf-proofs", "coherence-proofs"] + +[[bench]] +name = "proof_generation" +harness = false + +[[bench]] +name = "arena_throughput" +harness = false +``` + +#### Feature Propagation + +``` +ruvector-verified + |-- [always] lean-agentic =0.1.0 + |-- [always] thiserror 2.0 + |-- [hnsw-proofs] ruvector-core (hnsw feature) + |-- [rvf-proofs] rvf-types + rvf-crypto (ed25519) + ruvector-cognitive-container + |-- [coherence-proofs] ruvector-coherence + |-- [serde] serde + serde_json + lean-agentic/serde + +Downstream crates opt in: + ruvector-core/Cargo.toml: + [features] + formal-verification = ["dep:ruvector-verified", "ruvector-verified/hnsw-proofs"] +``` + +### 4.3 Error Types + +```rust +// crates/ruvector-verified/src/error.rs + +use thiserror::Error;

Migration Path + +### 9.1 Impact on Existing Users + +| Concern | Answer | +|---------|--------| +| **Existing crate APIs change?** | No. Zero changes to any existing public API. | +| **Default features change?** | No. No existing crate gains new default features. | +| **New transitive dependencies?** | Only if `formal-verification` feature is enabled. Otherwise, `Cargo.lock` gains one entry (`lean-agentic`), but it is never compiled. | +| **SemVer implications** | Adding `formal-verification` as a non-default feature to `ruvector-core` is a minor version bump (2.0.4 -> 2.1.0) under Rust SemVer conventions. | +| **Breaking changes** | None. The new crate is a leaf with no reverse dependencies initially. | + +### 9.2 Adoption Path + +1. **Phase 1-2**: `ruvector-verified` exists as an independent crate. Users who want verification add it explicitly: `cargo add ruvector-verified --features hnsw-proofs`. +2. **Phase 3+**: Downstream crates (e.g., `ruvector-core`) gain optional `formal-verification` feature flags. Users enable with: `cargo build --features ruvector-core/formal-verification`. +3. **No existing behavior changes** at any phase. Verification is purely additive. + +### 9.3 Publishing Sequence + +1. `lean-agentic` is already published (v0.1.0 on crates.io). No action needed. +2. `ruvector-verified` starts with `publish = false`. +3. When Phase 2 is complete and API stabilizes: set `publish = true`, publish as `ruvector-verified = "0.1.0"`. +4. `ruvector-verified-wasm` (Phase 4): publish after `ruvector-verified`. + +--- + +## 10. Implementation Plan + +### Phase 1: Foundation (Week 1-2) + +1. Add `lean-agentic = "=0.1.0"` to `[workspace.dependencies]` +2. Add `"crates/ruvector-verified"` to `[workspace.members]` +3.

Implement `ProofEnvironment` (Section 4.4) +6. Implement `vector_types.rs`: `mk_vector_type`, `mk_nat_literal`, `prove_dim_eq` +7. Implement `invariants.rs`: `register_builtins` for Nat, RuVec, Eq.refl +8. Unit tests (Section 7.1): all 5 tests passing +9. Benchmark: `arena_throughput` bench running, baseline established + +**Exit criteria**: `cargo test -p ruvector-verified` passes. `cargo bench -p ruvector-verified` runs. + +### Phase 2: Core Integration (Week 3-4) + +1. Enable `hnsw-proofs` feature, implement `verified_insert` +2. Add `rvf-proofs` feature, implement `proof_store.rs` (Section 4.5) +3. Implement `to_witness_entry()` and `sign_attestation()` +4. Integration tests (Section 7.2): verified insert round-trip, witness chain round-trip +5. Property-based tests (Section 7.3): proptest generators +6. Negative tests (Section 7.4): soundness verification +7. CI: create `.github/workflows/build-verified.yml` (Section 8.1) +8. Benchmark: `proof_generation` bench, verify < 1ms per op + +**Exit criteria**: `cargo test -p ruvector-verified --features all-proofs` passes. CI green. + +### Phase 3: Pipeline Verification (Week 5-6) + +1. Implement `pipeline.rs`: `VerifiedStage`, `compose_stages` (Section 4.4) +2. Map DNA pipeline stages (examples/dna ADR-001..015) to verified chain +3. Integrate with `ruvector-cognitive-container` via `WitnessChain`: + - `ProofAttestation` -> `to_witness_entry()` -> `WitnessChain::push()` +4. Implement proof serialization for `.rvf` containers via `rvf-types` +5. Tests: pipeline composition soundness, container round-trip + +**Exit criteria**: DNA pipeline stages compose without type errors.

CRDT commutativity proofs (`ruvector-delta-consensus`) +4. Create `ruvector-verified-wasm` with `wasm-bindgen` exports +5. WASM CI with binary size assertion (< 80KB) +6.

Ultra-Optimization: RuVector Performance Primitives for the Kernel + +### 15.1 Motivation + +lean-agentic's kernel achieves 0.3ns term equality via hash-consing, but the surrounding operations -- arena allocation, WHNF reduction, substitution, unification constraint solving -- use vanilla `HashMap` and `Vec` data structures.

Each `intern()` call may trigger HashMap resizing and Vec growth with per-element drop overhead. + +**Solution**: Replace the backing store with `ruvector-solver`'s `SolverArena` pattern -- a bump allocator with O(1) reset. + +```rust +// crates/ruvector-verified/src/fast_arena.rs + +use std::cell::RefCell; + +/// High-performance term arena using bump allocation. +/// Modeled after ruvector-solver's SolverArena (crates/ruvector-solver/src/arena.rs). +/// +/// Key differences from lean-agentic's default Arena: +/// - Single contiguous allocation (cache-friendly) +/// - O(1) reset reclaims all memory +/// - 64-byte cache-line alignment for SIMD access +/// - No per-term drop overhead +pub struct FastTermArena { + /// Backing buffer: contiguous, cache-aligned + buf: RefCell>, + /// Bump pointer + offset: RefCell, + /// Term count (for TermId generation) + count: RefCell, + /// Hash-consing cache: open-addressing with linear probe + /// Layout: [hash: u64, term_id: u32, padding: u32] x capacity + cache_buf: RefCell>, + cache_mask: usize, // capacity - 1 (power of 2) +} + +impl FastTermArena { + /// Pre-allocate for expected term count. + /// Typical: 4096 terms for a dimension proof, 65536 for pipeline verification. + pub fn with_capacity(max_terms: usize) -> Self { + let term_bytes = max_terms * std::mem::size_of::(); + let cache_cap = (max_terms * 2).next_power_of_two(); // 50% load factor + + Self { + buf: RefCell::new(vec![0u8; term_bytes]), + offset: RefCell::new(0), + count: RefCell::new(0), + cache_buf: RefCell::new(vec![0u64; cache_cap * 2]), // hash + id pairs + cache_mask: cache_cap - 1, + } + } + + /// Intern a term with open-addressing hash lookup. + /// Uses FxHash (multiply-shift) for speed over SipHash. + #[inline] + pub fn intern_fast(&self, kind: &TermKind) -> TermId { + let hash = fx_hash(kind); + let mask = self.cache_mask; + let cache = self.cache_buf.borrow(); + + // Linear probe with 4-wide unroll + let mut slot = (hash as usize) & mask; + for _ in 0..4 { + let stored_hash = cache[slot * 2]; + if stored_hash == hash { + // Potential hit -- verify structural equality + let id = cache[slot * 2 + 1] as u32; + return TermId(id); + } + if stored_hash == 0 { + break; // Empty slot -- cache miss + } + slot = (slot + 1) & mask; + } + drop(cache); + + // Cache miss: allocate via bump pointer + self.alloc_and_cache(kind, hash, slot) + } + + /// O(1) reset -- reclaim all terms. + /// Called between proof obligations. + pub fn reset(&self) { + *self.offset.borrow_mut() = 0; + *self.count.borrow_mut() = 0; + self.cache_buf.borrow_mut().fill(0); + } +} + +/// FxHash: multiply-shift hash (used by rustc internally). +/// 5x faster than SipHash for small keys. +#[inline] +fn fx_hash(kind: &TermKind) -> u64 { + // Hash the discriminant + first 8 bytes of payload + let discriminant = std::mem::discriminant(kind); + let mut h = 0xcbf29ce484222325u64; // FNV offset + h = h.wrapping_mul(0x100000001b3); // FNV prime + h ^= unsafe { std::mem::transmute_copy::<_, u64>(&discriminant) }; + h +} +``` + +**Performance**: Eliminates heap allocation in hot path. Reset between proofs is O(1) vs O(n) drop. + +### 15.4 Optimization 2: SIMD-Accelerated Hash-Consing + +**Problem**: Hash-consing equality check requires computing hash of `TermKind`, then comparing against cached candidates. Default `HashMap` uses SipHash (DoS-resistant but slow). + +**Solution**: Apply `ruvector-core`'s SIMD distance pattern for hash-table probing. + +```rust +// 4-wide parallel hash probe using the ILP pattern from +// ruvector-solver/src/cg.rs (dot_product_f64 with 4 accumulators) + +#[inline] +fn probe_4wide(cache: &[u64], hash: u64, mask: usize, start: usize) -> Option { + let s0 = start & mask; + let s1 = (start + 1) & mask; + let s2 = (start + 2) & mask; + let s3 = (start + 3) & mask; + + // 4 independent loads -- CPU can execute in parallel + let h0 = cache[s0 * 2]; + let h1 = cache[s1 * 2]; + let h2 = cache[s2 * 2]; + let h3 = cache[s3 * 2]; + + // 4 independent comparisons + if h0 == hash { return Some(cache[s0 * 2 + 1] as u32); } + if h1 == hash { return Some(cache[s1 * 2 + 1] as u32); } + if h2 == hash { return Some(cache[s2 * 2 + 1] as u32); } + if h3 == hash { return Some(cache[s3 * 2 + 1] as u32); } + + None // Continue probing +} +``` + +**On AVX2 targets** (feature-gated): + +```rust +#[cfg(all(feature = "simd", target_arch = "x86_64"))] +#[target_feature(enable = "avx2")] +unsafe fn probe_avx2(cache: &[u64], hash: u64, mask: usize, start: usize) -> Option { + use std::arch::x86_64::*; + + // Broadcast search hash to 4 lanes + let needle = _mm256_set1_epi64x(hash as i64); + + // Load 4 consecutive hash entries + let s = start & mask; + let ptr = cache.as_ptr().add(s * 2) as *const __m256i; + let entries = _mm256_loadu_si256(ptr); // [h0, id0, h1, id1] + + // Compare: yields 0xFFFF... on match + let cmp = _mm256_cmpeq_epi64(entries, needle); + let bitmask = _mm256_movemask_epi8(cmp); + + if bitmask != 0 { + let lane = bitmask.trailing_zeros() / 8; + let id_offset = s * 2 + (lane as usize) + 1; + return Some(cache[id_offset] as u32); + } + None +} +``` + +**Expected speedup**: 3-5x over `HashMap::get()` for the hash-consing hot path. + +### 15.5 Optimization 3: Fused Substitution + Shift Kernel + +**Problem**: WHNF substitution `t[x := s]` requires traversing the term, shifting De Bruijn indices, and rebuilding. The default implementation makes 3 passes: traverse, shift, rebuild. + +**Solution**: Apply `ruvector-solver/neumann.rs` fused residual pattern -- do it in one pass. + +```rust +/// Fused substitute-and-shift in a single traversal. +/// Modeled after ruvector-solver's fused_residual_norm_sq which combines +/// SpMV + subtraction + norm into one memory pass. +/// +/// Instead of: +/// pass 1: find variables to substitute +/// pass 2: shift remaining indices +/// pass 3: rebuild term +/// +/// We do all three in a single recursive descent. +pub fn fused_substitute_shift( + arena: &mut FastTermArena, + term: TermId, + var_idx: u32, // De Bruijn index to substitute + replacement: TermId, // The replacement term + shift: i32, // Current shift amount +) -> TermId { + match arena.kind(term) { + TermKind::Var(n) => { + if *n == var_idx { + replacement // Substitute + } else if *n > var_idx { + // Shift down: variable was bound above the substitution + arena.intern_fast(&TermKind::Var((*n as i32 + shift) as u32)) + } else { + term // Below substitution point -- unchanged (return same TermId) + } + } + TermKind::App(f, a) => { + let f2 = fused_substitute_shift(arena, *f, var_idx, replacement, shift); + let a2 = fused_substitute_shift(arena, *a, var_idx, replacement, shift); + // Short-circuit: if nothing changed, return original (hash-consing dedup) + if f2 == *f && a2 == *a { return term; } + arena.mk_app(f2, a2) + } + TermKind::Lam(binder, body) => { + let ty2 = fused_substitute_shift(arena, binder.ty, var_idx, replacement, shift); + // Under a binder: increment var_idx and shift + let body2 = fused_substitute_shift(arena, *body, var_idx + 1, replacement, shift); + if ty2 == binder.ty && body2 == *body { return term; } + let new_binder = Binder { ty: ty2, ..binder.clone() }; + arena.intern_fast(&TermKind::Lam(new_binder, body2)) + } + TermKind::Pi(binder, body) => { + let ty2 = fused_substitute_shift(arena, binder.ty, var_idx, replacement, shift); + let body2 = fused_substitute_shift(arena, *body, var_idx + 1, replacement, shift); + if ty2 == binder.ty && body2 == *body { return term; } + let new_binder = Binder { ty: ty2, ..binder.clone() }; + arena.intern_fast(&TermKind::Pi(new_binder, body2)) + } + // Sort, Const, Lit, MVar: no variables to substitute + _ => term, + } +} +``` + +**Key trick**: The `if f2 == *f && a2 == *a { return term; }` short-circuit leverages hash-consing -- if sub-terms are unchanged, the parent term is also unchanged, saving allocation. + +### 15.6 Optimization 4: Thread-Local Resource Pools + +**Problem**: Each proof obligation creates fresh `Context`, constraint `VecDeque`, and `HashSet` for unification. These allocate and drop on every call. + +**Solution**: Apply `ruvector-mincut/pool/mod.rs` pattern -- thread-local pools with auto-return. + +```rust +// Thread-local pool for proof-checking resources. +// Pattern from ruvector-mincut's BfsPool (90%+ hit rate after warmup). + +use std::cell::RefCell; +use std::collections::{VecDeque, HashSet}; + +thread_local! { + static PROOF_POOL: RefCell = RefCell::new(ProofResourcePool::new()); +} + +struct ProofResourcePool { + contexts: Vec, + constraint_queues: Vec>, + visited_sets: Vec>, + acquires: usize, + hits: usize, +} + +impl ProofResourcePool { + fn new() -> Self { + Self { + contexts: Vec::new(), + constraint_queues: Vec::new(), + visited_sets: Vec::new(), + acquires: 0, + hits: 0, + } + } +} + +/// Acquire pooled resources for a proof obligation. +/// Auto-returns to pool when `ProofResources` is dropped. +pub fn acquire_proof_resources() -> ProofResources { + PROOF_POOL.with(|pool| { + let mut p = pool.borrow_mut(); + p.acquires += 1; + + let ctx = p.contexts.pop().unwrap_or_else(Context::new); + let queue = p.constraint_queues.pop().unwrap_or_default(); + let visited = p.visited_sets.pop().unwrap_or_default(); + + if !p.contexts.is_empty() || !p.constraint_queues.is_empty() { + p.hits += 1; + } + + ProofResources { ctx, queue, visited } + }) +} + +pub struct ProofResources { + pub ctx: Context, + pub queue: VecDeque, + pub visited: HashSet, +} + +impl Drop for ProofResources { + fn drop(&mut self) { + // Clear but retain capacity, then return to pool + self.ctx.clear(); + self.queue.clear(); + self.visited.clear(); + + PROOF_POOL.with(|pool| { + let mut p = pool.borrow_mut(); + p.contexts.push(std::mem::take(&mut self.ctx)); + p.constraint_queues.push(std::mem::take(&mut self.queue)); + p.visited_sets.push(std::mem::take(&mut self.visited)); + }); + } +} +``` + +**Expected**: After warmup, 90%+ pool hit rate.
