Formal Verification

Status: Typing.v: 0 Admitted, ShadowPrices.v: 4 Admitted (deep LP theory)

Component Theorems Admitted Proof Assistant
Type System (Typing.v) 4 0 Coq
Shadow Prices (ShadowPrices.v) 8 4 Coq
Resource Tracking (ResourceTracking.agda) 9 0 Agda

Key Theorems Proved

Type System (Coq - all proved):

  1. Progress theorem (well-typed programs don't get stuck)
  2. Preservation theorem (evaluation preserves types)
  3. Soundness theorem (combination of progress + preservation)
  4. Dimensional type safety

Shadow Prices (Coq - 4/8 proved, 4 Admitted):

  • Proved: non-negativity, convergence, economic optimality, budget relationship
  • Admitted: strong duality, dual variables, complementary slackness, positive/binding (deep LP theory requiring Farkas' lemma)

Resource Tracking (Agda - all proved):

  1. Tracking soundness (tracked usage = actual usage)
  2. Usage monotonicity
  3. Deterministic tracking
  4. Budget enforcement correctness
  5. Resource leak freedom
  6. Consumption associativity
  7. Zero consumption identity
  8. Budget inheritance
  9. Multi-resource tracking independence

What Does NOT Work Yet

  • WASM GC: Bump allocator defined but not wired to linear memory
  • LLVM end-to-end linking: Static library exists, automatic linking not wired
  • Runtime OS metrics: Scheduler/profiler/carbon implemented but not wired to real OS metrics (except RSS on Linux)
  • Macro expansion in MIR: MacroCall lowered to HIR but MIR emits Nop
  • Measured benchmarks: None — all performance claims are projections
  • Registry deployment: Server stub exists, not deployed
  • ShadowPrices.v: 4 Admitted proofs (deep LP theory)

Next Steps

  1. Wire WASM GC — connect bump allocator to linear memory
  2. Automate LLVM linking — integrate rt-native into build command
  3. Wire OS metrics — connect runtime to real system metrics
  4. Deploy registry — package registry server
  5. Complete ShadowPrices.v — resolve remaining 4 Admitted proofs
  6. Add benchmarks — measure actual performance

Honest assessment: Eclexia is a working alpha compiler with a functional pipeline from source to bytecode VM, with three real code-generation backends (WASM, LLVM, Cranelift). The economics-as-code concepts (shadow prices, adaptive functions, resource tracking) are implemented in the runtime with real defaults and tests. All 18 SONNET-TASKS completion tasks are done. Not production-ready. Not feature-complete. Active development.

  • Done - Implemented and tested
  • In Progress - Partially implemented
  • Planned - Not started yet
  • Blocked - Waiting on dependencies
