+## Component Readiness Assessment
+
+| Field | Value |
+|-------|-------|
+| Component | julia-the-viper (JTV) |
+| Version | 0.1.0 |
+| Date | 2026-04-04 |
+| Assessor | Claude (automated) + Jonathan D.A. Jewell |
+| CRG Grade | **C+** (approaching B) |
+| Release Stage | Alpha (home context) |
+
+## Test Evidence Summary
+
+- **339 passing tests** across 6 test suites
+- **41 property-based tests** (proptest) covering all 7 number systems
+- **35 security/boundary tests** validating Harvard Architecture separation
+- **20 contract tests** verifying addition-only, purity, and reversibility invariants
+- **2 fuzz targets** (libfuzzer) for parser safety
+- **2 benchmark suites** (parser throughput + interpreter performance)
+- **80K Lean 4 proofs** (security, type soundness, algebraic properties)
+- **4.7K Idris2 ABI proofs** (dependent type definitions)
+- **51 conformance programs** (30 valid + 21 invalid)

+## 14 Aspect Dimensions
+
+| Aspect | Grade | Notes |
+|--------|-------|-------|
+| Security | A | Grammatical injection impossibility (Lean proof + 35 tests) |
+| Safety | A | Addition-only + purity enforced at type level, no dangerous patterns |
+| Functionality | B | 339 tests, 2 conformance gaps (string/range) |
+| Performance | B | Benchmarked, baselines not yet tracked in CI |
+| Dependability | C | Overflow handled, no crash recovery tests |
+| Maintainability | B | Modular crates, deep annotation, `just doctor` |
+| Reproducibility | C | flake.nix present, not fully tested |
+| Interoperability | C | WASM target exists, FFI untested |
+| Portability | C | Linux CI only |
+| Observability | C | Debug crate exists |
+| Usability | C | LSP exists, untested |
+| Versability | D | No version matrix |
+| Accessibility | N/A | CLI tool |
+| Privacy | N/A | No user data |
+
+## Formal Proof Coverage
+
+| Property | Prover | File | Status |
+|----------|--------|------|--------|
+| Code injection impossibility | Lean 4 | JtvSecurity.lean | Proven (Theorem 2.3) |
+| Type soundness | Lean 4 | JtvTypes.lean | Proven |
+| Data language totality | Lean 4 | JtvTheorems.lean | Proven |
+| Operational semantics | Lean 4 | JtvOperational.lean | Proven |
+| Algebraic properties | Lean 4 | JtvExtended.lean | Proven |
+| Harvard Architecture separation | Idris2 | Types.idr | Proven |
+| Tropical semiring laws | Idris2 | TropicalSemiring.idr (007/) | Proven |
+| CNO identity | Idris2 | CNO.idr (007/) | Proven (0 sorry) |
+| Reversibility round-trip | Rust proptest | property_tests.rs | 4 properties |
+
+## Gaps to CRG B
+
+1. Mutation testing (cargo-mutants, >80% kill rate)
+2. Fix 2 conformance failures (string in data_expr, for-in range syntax)
+3. Version compatibility testing
+4. Cross-platform CI (macOS, Windows)
+5. Zig FFI integration tests
+6. Coverage reporting
+
+## Specialist JTV Properties Covered
+
+| Property | Test Type | Count | Coverage |
+|----------|-----------|-------|----------|
+| Addition-only invariant | Contract + Grammar | 20 | DataExpr enum exhaustive, grammar rejects */÷/% |
+| 7 number systems | Property + Unit | 49+ | All types: commutativity, associativity, identity, inverse |
+| Harvard boundary | P2P + Security | 35 | Data cannot contain control, control reads data one-way |
+| Reversibility identity | Property + Contract | 8+ | forward+reverse=identity across types and multi-variable |
+| Purity lattice | Contract | 7 | Total < Pure < Impure, enforcement tested |
+| Code injection impossibility | Security + Lean proof | 10+ | No eval/exec, strings are data, keywords reserved |
+| Overflow safety | Property | 4 | Never panics on arbitrary i64 input |
