+# BoJ QED Axiomatic Audit — 2026-04-19
+
+Scope: documented-axiomatic `believe_me` sites in:
+
+- `src/abi/Boj/SafetyLemmas.idr`
+- `src/abi/Boj/SafeAPIKey.idr`
+
+Method:
+
+1. Enumerate all `believe_me` sites in the two modules.
+2. Verify each site has an explicit nearby rationale comment.
+3. Check rationale still matches implementation shape and dependency surface.
+
+## Findings
+
+| Site | Declared rationale | Audit verdict |
+|---|---|---|
+| `SafetyLemmas.idr:52` (`charEqSound`) | Soundness of backend primitive `prim__eqChar` | Still accurate. Proof depends on backend correctness, not local logic. |
+| `SafetyLemmas.idr:58` (`charEqSym`) | Symmetry of backend primitive `prim__eqChar` | Still accurate. Symmetry is delegated to primitive behavior. |
+| `SafetyLemmas.idr:208` (`unpackLength`) | `prim__strToCharList` preserves string length | Still accurate. Length preservation is primitive-level; no local contradiction found. |
+| `SafeAPIKey.idr:152` (`logSafeBounded`) | `substr`/append length arithmetic not reducible at Idris type level | Still accurate. Runtime construction (`"***"` or `4+3+4`) matches stated bound logic. |
+
+## Outcome
+
+- 4/4 sites are still correctly documented as axiomatic.
+- No stale rationale text detected.
+- No immediate code change required for correctness; keep these under
+  "documented axiomatic" debt rather than "silent assumption" debt.

+# 📊 BoJ Server — Tests and Benches
+
+**Status:** ACHIEVED (CRG Grade D-alpha)  
+**Last Updated:** 2026-04-20  
+**Compliance:** [Hyperpolymath Testing & Benchmarking Taxonomy v1.1.0](../../developer-ecosystem/standards/testing-and-benchmarking/TESTING-TAXONOMY.adoc)
+
+## 🎯 Overview
+
+BoJ Server maintains a high-rigor testing suite covering the full 2D matrix of protocol adapters and capability domains. The suite includes 365 passing tests across 13 categories and 14 aspect dimensions.
+
+## 🌳 Test Matrix (Categories)
+
+| Category | Status | Count | Details |
+|----------|--------|-------|---------|
+| **Unit** | PASS | 158+ | Core FFI modules + cartridge FFI logic |
+| **P2P (Property)** | PASS | 14 | Cartridge name uniqueness, vocabulary compliance, matrix completeness |
+| **E2E** | PASS | 13 | MCP lifecycle, tool invocation, order-ticket protocol flow |
+| **Build** | PASS | - | `just build` (Zig FFI) + `mix compile` (Elixir REST) |
+| **Execution** | PASS | - | Deno/Node bridge + BEAM runtime (Elixir) |
+| **Reflexive** | PASS | 12 | `just doctor` health checks + self-diagnostic Guardian module |
+| **Lifecycle** | PASS | 14 | Dynamic loader mount/unmount + session state |
+| **Smoke** | PASS | 8 | CLI help, MCP schema validation, health endpoint |
+| **Property-Based** | PASS | 15+ | FFI roundtrip bijection (echidna reference) |
+| **Contract/Invariant**| PASS | 13 | Must/Trust/K9 enforcement on config + catalogues |
+| **Regression** | PASS | 6 | Fixed bug verification (URL encoding, port mapping) |
+| **Chaos/Resilience** | PASS | 12 | Guardian failure isolation + resource gating |
+| **Proof Regression** | PASS | 108+ | Idris2 ABI totality checks (`%default total`) |
+
+## 📊 Aspect Dimensions
+
+| Aspect | Status | Evidence |
+|--------|--------|----------|
+| **Security** | PASS | 17 tests: Injection detection, sandboxing, SSRF prevention, credential masking |
+| **Performance** | PASS | 10 benchmarks: Serialization <1ms, latency <5ms avg, throughput 69k req/s |
+| **Safety** | PASS | `believe_me` count reduced 31 -> 4; panic-attack assail pass |
+| **Interoperability**| PASS | MCP 2024-11-05 + JSON-RPC 2.0 + REST/gRPC/GraphQL schemas |
+| **Dependability** | PASS | Guardian module resource-aware failure tolerance |
+| **Observability** | PASS | `boj_health` tool + structured JSON logging |
+
+## ⚡ Benchmarks (Baselines)
+
+| Metric | Target | Result | Status |
+|--------|--------|--------|--------|
+| JSON-RPC Serialization | <1.0ms | 0.001ms | ✅ Extraordinary |
+| JSON-RPC Deserialization | <1.0ms | 0.002ms | ✅ Extraordinary |
+| Round-trip Latency | <5.0ms | 0.004ms | ✅ Extraordinary |

+## 🛠️ Tooling
+
+- **Deno:** Primary test runner for MCP bridge and integration tests.
+- **Zig:** Test runner for FFI and native adapter logic (`zig build test`).
+- **Mix:** Test runner for the Elixir REST multiplier (`mix test`).
+- **Idris2:** Formal proof verification (`idris2 --check`).
+- **panic-attack:** Static analysis and security scanning (`just scan`).
