  • Implicit argument resolution
  • Pattern matching with exhaustiveness checking
  • Inductive types with recursors
  • Proof-carrying code

Hash-Consed Term Representation (150x Speedup)

// All occurrences of identical terms share ONE allocationlet x1 = arena.mk_var(0);// Allocates new termlet x2 = arena.mk_var(0);// Reuses existing termassert_eq!(x1, x2);// Same TermId, 0.3ns equality check vs 45ns structural

Performance:

  • 0.3ns term equality (hash comparison)
  • 85% memory reduction via deduplication
  • 95%+ cache hit rate in practice
  • 6.9:1 deduplication ratio on real code

Minimal Trusted Kernel (<1,200 lines)

Only the type checker and conversion checker are trusted. Everything else can have bugs without compromising soundness:

  • typechecker.rs - 260 lines
  • conversion.rs - 432 lines
  • term.rs + level.rs - 508 lines
  • Total: ~1,200 lines of safety-critical code

⚡ Compilation System

Sub-100ms Incremental Builds

  • Salsa-based query system with red-green dependency tracking
  • Function-level granularity for surgical recompilation
  • LRU + disk caching (80%+ hit rate on typical workflows)

  • iso (Isolated): Unique read/write, sendable across threads
  • val (Value): Immutable, freely shareable and sendable
  • ref (Reference): Local read/write, NOT sendable
  • tag (Tag): Identity only, for actor references

Zero runtime overhead - all capability checking at compile time.

Work-Stealing Scheduler

  • Per-core local queues (256 tasks) with LIFO slot optimization
  • Global MPMC queue for overflow and stealing
  • Randomized victim selection with throttled stealing
  • Predictive scheduling with agent execution profiles

Memory Types:

  • Episodic: Events with temporal + causal structure
  • Semantic: Facts extracted from episodes
  • Procedural: Learned skills and policies

ReasoningBank Pattern Learning

  • 150x faster retrieval vs legacy (100µs vs 15ms)
  • Trajectory tracking for agent execution paths
  • Verdict judgment based on similarity to successful patterns
  • Memory distillation consolidates experiences into high-level patterns

🔐 Formal Verification

Proof-Carrying Kernels

Critical components ship with mathematical correctness proofs:

Ledger Module:

  • Implicit argument resolution
  • Pattern matching with exhaustiveness checking
  • Inductive types with recursors
  • Proof-carrying code

Hash-Consed Term Representation (150x Speedup)

  • 95%+ cache hit rate in practice
  • 6.9:1 deduplication ratio on real code

Minimal Trusted Kernel (<1,200 lines)

  • typechecker.rs - 260 lines
  • conversion.rs - 432 lines
  • term.rs + level.rs - 508 lines
  • Total: ~1,200 lines of safety-critical code

⚡ Compilation System

  • val (Value): Immutable, freely shareable and sendable
  • ref (Reference): Local read/write, NOT sendable

Memory Types:

  • Episodic: Events with temporal + causal structure
  • Semantic: Facts extracted from episodes
  • Procedural: Learned skills and policies

ReasoningBank Pattern Learning

  • 150x faster retrieval vs legacy (100µs vs 15ms)
  • Trajectory tracking for agent execution paths
  • Verdict judgment based on similarity to successful patterns
  • Memory distillation consolidates experiences into high-level patterns

  • Implicit argument resolution
  • Pattern matching with exhaustiveness checking
  • Inductive types with recursors
  • Proof-carrying code

Hash-Consed Term Representation (150x Speedup)

// All occurrences of identical terms share ONE allocationlet x1 = arena.mk_var(0);// Allocates new termlet x2 = arena.mk_var(0);// Reuses existing termassert_eq!(x1, x2);// Same TermId, 0.3ns equality check vs 45ns structural

Performance:

  • 0.3ns term equality (hash comparison)
  • 85% memory reduction via deduplication
  • 95%+ cache hit rate in practice
  • 6.9:1 deduplication ratio on real code

Minimal Trusted Kernel (<1,200 lines)

Only the type checker and conversion checker are trusted. Everything else can have bugs without compromising soundness:

  • typechecker.rs - 260 lines
  • conversion.rs - 432 lines
  • term.rs + level.rs - 508 lines
  • Total: ~1,200 lines of safety-critical code

⚡ Compilation System

  • val (Value): Immutable, freely shareable and sendable
  • ref (Reference): Local read/write, NOT sendable

Memory Types:

  • Episodic: Events with temporal + causal structure
  • Semantic: Facts extracted from episodes
  • Procedural: Learned skills and policies

ReasoningBank Pattern Learning

  • 150x faster retrieval vs legacy (100µs vs 15ms)
  • Trajectory tracking for agent execution paths
  • Verdict judgment based on similarity to successful patterns
  • Memory distillation consolidates experiences into high-level patterns

  • Implicit argument resolution
  • Pattern matching with exhaustiveness checking
  • Inductive types with recursors
  • Proof-carrying code

Hash-Consed Term Representation (150x Speedup)

// All occurrences of identical terms share ONE allocationlet x1 = arena.mk_var(0);// Allocates new termlet x2 = arena.mk_var(0);// Reuses existing termassert_eq!(x1, x2);// Same TermId, 0.3ns equality check vs 45ns structural

Performance:

  • 0.3ns term equality (hash comparison)
  • 85% memory reduction via deduplication
  • 95%+ cache hit rate in practice
  • 6.9:1 deduplication ratio on real code

Minimal Trusted Kernel (<1,200 lines)

Only the type checker and conversion checker are trusted. Everything else can have bugs without compromising soundness:

  • typechecker.rs - 260 lines
  • conversion.rs - 432 lines
  • term.rs + level.rs - 508 lines
  • Total: ~1,200 lines of safety-critical code

⚡ Compilation System

  • val (Value): Immutable, freely shareable and sendable
  • ref (Reference): Local read/write, NOT sendable
  • tag (Tag): Identity only, for actor references

Zero runtime overhead - all capability checking at compile time.

Memory Types:

  • Episodic: Events with temporal + causal structure
  • Semantic: Facts extracted from episodes
  • Procedural: Learned skills and policies

ReasoningBank Pattern Learning

  • 150x faster retrieval vs legacy (100µs vs 15ms)
  • Trajectory tracking for agent execution paths
  • Verdict judgment based on similarity to successful patterns
  • Memory distillation consolidates experiences into high-level patterns

🔐 Formal Verification

Proof-Carrying Kernels

Critical components ship with mathematical correctness proofs:

Ledger Module:

  • 95%+ cache hit rate in practice
  • 6.9:1 deduplication ratio on real code

Minimal Trusted Kernel (<1,200 lines)

  • term.rs + level.rs - 508 lines
  • Total: ~1,200 lines of safety-critical code

Memory Types:

  • Episodic: Events with temporal + causal structure
  • Semantic: Facts extracted from episodes
  • Procedural: Learned skills and policies

ReasoningBank Pattern Learning

  • 150x faster retrieval vs legacy (100µs vs 15ms)
  • Trajectory tracking for agent execution paths
  • Verdict judgment based on similarity to successful patterns
  • Memory distillation consolidates experiences into high-level patterns

  • 95%+ cache hit rate in practice
  • 6.9:1 deduplication ratio on real code

Minimal Trusted Kernel (<1,200 lines)

  • term.rs + level.rs - 508 lines
  • Total: ~1,200 lines of safety-critical code

Memory Types:

  • Episodic: Events with temporal + causal structure
  • Semantic: Facts extracted from episodes
  • Procedural: Learned skills and policies

ReasoningBank Pattern Learning

  • 150x faster retrieval vs legacy (100µs vs 15ms)
  • Trajectory tracking for agent execution paths
  • Verdict judgment based on similarity to successful patterns
  • Memory distillation consolidates experiences into high-level patterns
