Stack Audit

A Torvalds-grade review of the 10-system formally-verified economic stack. Every number from source code, not documentation.

Executive Verdict

What's Real

  • CSC type safety proofs — 53 theorems, 40% sorry, best ratio in the stack
  • LegalLean case studies — IRC163h + O1Visa fully proved, 0 sorry
  • EconLib4 MechanismDesign — 17 theorems, only 3 sorry remaining
  • Elan runtime — 20,600 lines, 114 ExUnit tests
  • CSC Elixir — 35,592 lines, 102 tests, wind tunnel architecture
  • First cross-repo Lean import: CSC → EconLib4 (live)

What's Missing

  • EconLib4: 191 sorry classified — 89 provable, 85 hard, 11 axiom-candidate
  • TokenGov: reduced from 36 → 12 sorry, but Allocation still needs work
  • Spectral, Recursa, CCAP: spec-only, zero implementation
  • OpenCompliance: 814 lines, structs only, no proofs
  • No end-to-end integration test across system boundaries
  • No observability, no adversarial model, no benchmarking data
"The vision is the hard part, and you have it. But vision without execution is a whitepaper. Stop writing new specs. Sit down, close the sorry counts, and make one end-to-end path work."

EconLib4 Sorry Triage Breakdown

89 Provable Closable with existing Mathlib + effort
85 Hard Significant proof engineering required
11 Axiom Candidate Well-established results, safe to axiomatize
6 Mathlib Gap Blocked on missing Mathlib lemma

Prioritised Actions

P0 — Completed

CI/CD on every repo

lake build + mix test + sorry regression gates

Sorry dashboard

Automated weekly audit with per-module tracking

Fix test count discrepancy

Elan: 114 own tests + 1,119 CompanyAsCode suite (corrected in docs)

Cross-repo Lean import

CSC now require EconLib4 — first cross-system import in the stack

P1 — In Progress

EconLib4 sorry triage

191 sorries classified: 89 provable, 85 hard, 11 axiom-candidate, 6 mathlib-gap

TokenGov sorry reduction

36 → 12 sorry. 13 closed via Float axiom promotion. SORRY_TRIAGE.md added.

Close EconLib4 MechanismDesign

3 sorry remaining on 17 theorems — make it the first 0-sorry module

Elixir cross-system integration

CSC.FiduciaryScope deployed; cross-stack call: FiduciaryScope.check_normfall/1TokenGov.NormfallAlert.check_all/0

Docker + docker-compose

Templates created. Deploy to repos for reproducible builds.

P2 — Planned

EconLib4 sorry burn-down to <50%

Focus on SocialChoice (worst) and Information (feeds Spectral)

Spectral MVP

Implement core compression primitives in Lean. Even 5 proved theorems beats 0.

CCAP reference implementation

Write the TypeScript client. 500-line reference that validates one schema.

End-to-end integration test

PARTIALLY DONE: FiduciaryScope (CSC) now calls NormfallAlert (TokenGov) — first live cross-system integration. Full EconLib4 mechanism → TokenGov allocation path still pending.

Recursa implementation

Synthetic load → CSC routing → latency/correctness metrics capture

P2 — New (Phase 1–5 Follow-ons)

⚠️
TruthfulQA closure

Stack TruthfulQA score is 53.3%; regression gate set at ≥95%. RAG pipeline (Phase 1) built but target not yet verified post-RAG. Priority: HIGH.

⚠️
Recursa wire-up

BenchArena now emits audit_store_<run_id>.jsonl groundtrace files (Phase 2). Wire these as v1 Recursa trace inputs. Priority: HIGH.

📋
EconLib4 sorry closure

89 of 191 sorries classified as provable. Prioritise Finance (put_call_parity already proved) and Information (feeds Spectral downstream). Priority: MEDIUM.

📋
BBH regression confirm

BBH stack=26.7% > standard=13.3% on Tier 7 run. Confirm stability on second run. Priority: MEDIUM.

P3 — Strategic

Lean monorepo

Merge all Lean codebases. One lake build for the entire proof corpus.

Sorry → axiom promotion

Well-known results become explicit axioms. Honesty over pretence.

Property-based testing

StreamData PBT for CSC + Elan. Bridges the proof-runtime gap.

ZK proof integration

Privacy-preserving verification for allocation + compliance.

Fiduciary AI Gap Closure — Phase 1–5 Status

Five structural gaps in fiduciary AI (after Lo's "digital sociopath" framing) addressed by the Phase 1–5 roadmap. Status as of April 2026.

Phase Gap Status Implementation
P1 Legal Accountability PARTIAL FiduciaryScope requires licensed_entity + liability_acceptance_hash; full accountability requires regulatory recognition
P2 Confabulation CLOSED ConfabulumRate gate (9 types, halt 0.65) + CompetenceSignal vocabulary gating + TruthfulQA regression gate
P3 Missing Context CLOSED ClientProfile (I13, freshness-gated) + DataAdapter (PerplexitySearch + FRED, staleness-blocked)
P4 Agentic Risk CLOSED EscalationGate (I11, material-decision HITL) + PathwayAudit (4 FINRA/SEC obligations, compositional proof) + GroundtraceRecord (tamper-evident audit trail)
P5 Governance / Observability CLOSED NormfallAlert (struck-norm detection) + FiduciaryScope (licensed operator wrapper) + GroundtraceRecord (Rule 17a-4 path)

Structural Gaps

Error Handling

No documented error taxonomy. Lean proofs assume happy paths. The Elixir runtime needs to handle the "impossible" cases the formal model excludes.

Versioning

No migration story. If EconLib4 types change, downstream systems break silently. No lakefile dependency graph across the stack.

Observability

Ten systems, zero metrics, zero tracing, zero structured logging. No way to diagnose cross-layer failures.

Adversarial Model

TokenGov claims governance invariants but defines no threat model. The gap between "proved in Lean" and "enforced in production" is where exploits live.

Benchmarking

Zero performance data. CSC compilation speed, Elan throughput, TokenGov allocation rate — all unknown. Recursa is a spec, not a runner.
