| 2 | + |
| 3 | +**Test #:** 05 (launch-hygiene re-validation) · **Run date:** 2026-06-19 |
| 4 | +**Branch:** `chore/launch-hygiene` · **Host:** local dev sandbox (`jinn-dev`) |
| 5 | +**See also:** [`BENCHMARKS-01.md`](BENCHMARKS-01.md) · [`BENCHMARKS-02.md`](BENCHMARKS-02.md) · [`BENCHMARKS-03.md`](BENCHMARKS-03.md) · [`BENCHMARKS-04.md`](BENCHMARKS-04.md) |
| 6 | + |
| 7 | +> Purpose: re-run the full **userspace** test + benchmark suite after the |
| 8 | +> launch-hygiene pass (advisory-ID rename, README register fix, doc cleanups — |
| 9 | +> all docs/comments, **no logic**) to confirm behavior and performance are |
| 10 | +> unchanged. This host runs the **same CPU family and kernel** as Run 01 |
| 11 | +> (AMD Ryzen 5 7520U / Debian 13 / kernel 6.12), so the numbers are directly |
| 12 | +> comparable to that baseline. |

| 16 | +## Environment |
| 17 | + |
| 18 | +| | | |
| 19 | +|---|---| |
| 20 | +| CPU | **AMD Ryzen 5 7520U** (8 threads, scaling ~83%, max 4.38 GHz) — same model as Run 01 | |
| 21 | +| Distribution | **Debian 13** (trixie family) | |
| 22 | +| Kernel | **Linux 6.12.90+deb13.1-amd64** | |
| 23 | +| RAM | ~5.75 GiB | |
| 24 | +| `/tmp` | **tmpfs** — audit log + lineage are CPU-isolated from disk-fsync latency (as in Run 03/04) | |
| 25 | +| Toolchain | rustc/cargo **1.95.0**, release profile, clang 19 | |
| 26 | +| Privilege | **uid 1000, no `bpftool`** → kernel-LSM Tier 4 (armed allow/deny) **not run here** | |
| 27 | + |
| 28 | +> **Scope note.** Kernel in-kernel allow/deny enforcement (Tier 4) requires root + |
| 29 | +> BPF load and is **not** exercised on this unprivileged sandbox. It is already |
| 30 | +> validated on three real hosts in [`BENCHMARKS-01..04`](BENCHMARKS-04.md) |
| 31 | +> (Debian 6.12, Ubuntu 6.17, AlmaLinux 5.14 — 2,500–2,750 ops, 0 fail-open). |
| 32 | +> This run covers the **full automated suite + userspace performance**. |
| 33 | +
|
| 34 | +--- |
| 35 | + |
| 36 | +## 1. Full automated test suite |
| 37 | + |
| 38 | +`cargo test --workspace --release`: |
| 39 | + |
| 40 | +| Binary | Result | |
| 41 | +|---|---| |
| 42 | +| `ts_checker` (Z3 SMT) | 4 passed | |
| 43 | +| `ts_cli` unit | 87 passed | |
| 44 | +| `integration` | 13 passed | |
| 45 | +| `swarm_attack` (adversarial) | 12 passed | |
| 46 | +| `kernel_lsm` (Tier 4) | 6 **ignored** (env-gated: needs root + BPF) | |
| 47 | + |
| 48 | +> **116 passed · 0 failed · 6 ignored** (122 defined). Identical pass profile to |
| 49 | +> Run 04. The launch-hygiene changes did not alter any behavior. |
| 50 | +
|
| 51 | +## 2. Attack resistance (adversarial suite) |
| 52 | + |
| 53 | +`swarm_attack`: **12/12 passed, 0 fail-open** — replay storm, signature forgery, |
| 54 | +intent injection, quota abuse, anonymous flood, impersonation, path traversal, |
| 55 | +forged delegation, bad-protocol, and the all-at-once mixed assault. |
| 56 | + |
| 57 | +--- |
| 58 | + |
| 59 | +## 3. Userspace latency & throughput (`cargo bench --bench stress_bench`) |
| 60 | + |
| 61 | +### Single-client latency (10,000 sequential, full decision pipeline) |
| 62 | + |
| 63 | +| Percentile | Run 05 (Ryzen 5 7520U) | Run 01 baseline (same CPU) | |
| 64 | +|---|---|---| |
| 65 | +| P50 | **259 µs** | 257 µs | |
| 66 | +| P75 | 304 µs | — | |
| 67 | +| P90 | 435 µs | — | |
| 68 | +| P95 | **533 µs** | 366 µs | |
| 69 | +| P99 | **782 µs** | 463 µs | |
| 70 | +| P99.9 | 1,243 µs | — | |
| 71 | +| Max | 2,962 µs | 1,900 µs | |
| 72 | +| Single-client RPS | **~3,219** | ~3,640 | |
| 73 | + |
| 74 | +> P50 matches Run 01 to within noise (259 vs 257 µs). Tail percentiles (P95/P99) |
| 75 | +> are higher here — this is a **shared, non-CPU-isolated sandbox** at ~83% scaling, |
| 76 | +> not a dedicated host, so tail latency is noisier. The median (the pipeline's |
| 77 | +> real cost) is unchanged. |
| 78 | +
|
| 79 | +### Concurrent throughput (tmpfs `/tmp`; 0 errors at every level) |
| 80 | + |
| 81 | +| Agents | Total RPS | P50 | P95 | Errors | |
| 82 | +|---|---:|---:|---:|---:| |
| 83 | +| 10 | **6,208** | 1,220 µs | 1,874 µs | 0 | |
| 84 | +| 50 | 6,055 | 1,220 µs | 2,432 µs | 0 | |
| 85 | +| 100 | 6,159 | 1,233 µs | 2,535 µs | 0 | |
| 86 | +| 500 | 5,741 | 1,252 µs | 37,107 µs | 0 | |
| 87 | + |
| 88 | +> Peak **~6,208 RPS**, flat to 100 concurrent agents, **0 errors** throughout. |
| 89 | +> At 500 agents throughput holds but the P95 tail balloons (scheduling |
| 90 | +> congestion on 8 threads) — consistent with Run 01 (~6,500 peak). |
| 91 | +
|
| 92 | +### Mixed allow/deny (70/30) |
| 93 | + |
| 94 | +5,000 requests → **3,500 allow / 1,500 deny classified correctly, 0 |
| 95 | +misclassifications** (~3,517 RPS). |
| 96 | + |
| 97 | +### Saturation sweep |
| 98 | + |
| 99 | +| Threads | RPS | P99 | |
| 100 | +|---|---:|---:| |
| 101 | +| 2 | 4,556 | 1 ms | |
| 102 | +| 4 | 4,809 | 1 ms | |
| 103 | +| 8 | 5,111 | 2 ms | |
| 104 | +| 16 | 4,781 | 5 ms | |
| 105 | +| 32 | 4,888 | 9 ms | |
| 106 | +| 64 | **saturated** (P99 > 10 ms) | — | |
| 107 | + |
| 108 | +--- |
| 109 | + |
| 110 | +## 4. Component micro-benchmarks (criterion) |
| 111 | + |
| 112 | +| Path | Median | Throughput | |
| 113 | +|---|---:|---:| |
| 114 | +| Core decision pipeline (in-process) | **73.2 µs** | ~13.6 K/s | |
| 115 | +| UDS framed roundtrip (persistent conn) | **16.2 µs** | ~61.6 K/s | |
| 116 | +| End-to-end serial roundtrip (new conn/request) | **151.1 µs** | ~6.6 K/s | |
| 117 | + |
| 118 | +> The UDS transport (~16 µs) is a small fraction of the full decision (~73 µs+); |
| 119 | +> the pipeline, not the socket, dominates. *(The persistent-connection case in |
| 120 | +> `socket_throughput` hit a `BrokenPipe` in the bench harness mid-run — a |
| 121 | +> harness-robustness quirk, not a daemon fault; the e2e new-connection figure |
| 122 | +> above completed cleanly.)* |
| 123 | +
|
| 124 | +--- |
| 125 | + |
| 126 | +## 5. Scope & honesty notes |
| 127 | + |
| 128 | +- Userspace only; **kernel Tier 4 not run on this unprivileged sandbox** — see |
| 129 | + Runs 01–04 for live in-kernel enforcement. |
| 130 | +- Shared sandbox at ~83% CPU scaling: treat **P50/medians** as representative and |
| 131 | + **tails** as noisier than a dedicated host would show. |
| 132 | +- Still a validated research prototype / controlled-pilot MVP, not independently |
| 133 | + audited. See [`THREAT_MODEL.md`](THREAT_MODEL.md) and |
| 134 | + [`SECURITY/ADVISORIES.md`](SECURITY/ADVISORIES.md). |
| 135 | + |
| 136 | +**Bottom line:** post-launch-hygiene, the suite is **116/116 green (0 fail-open |
| 137 | +in the adversarial suite)** and userspace performance is in line with the Run 01 |
| 138 | +baseline on identical silicon — confirming the docs/comment-only hygiene pass |
| 139 | +changed nothing operational. |
