It watches each step an agent takes and answers closed questions about it in a single forward pass, with calibrated probabilities, so a monitor can act on confident answers and defer the rest to a person or a larger model.\n\nIt comes in two parts:\n\n- **`athr_checker.py`** (plain Python, standard library only) does every check with one provably right answer: the policy verdict on a tool call (tool list, paths, hosts, programs in a shell command, credentials, limits), delegated authority, the facts about an action's reach, and a voice agent's permitted list. Its 39 security edge cases (39 passing) run before anything else.\n- **The model** does the judgment: whether a step drifts from the task and why, whether the agent's own report is faithful, how severe an action is in context, whether content tries to hijack the agent, which action a spoken request asks for, and whether two speech recognizers heard the same command (both transcripts normalised by the checker first).\n\n| | nano | base |\n| --- | --- | --- |\n| Parameters | 793,729 | 12,268,033 |\n| Size on disk (fp16) | 1.6 MB | 24.5 MB |\n| Test accuracy (micro / macro) | 88.6% / 90.4% | 87.3% / 89.4% |\n| Calibration error (ECE, after temperature) | 0.034 | 0.025 |\n| GPU latency, one decision | 5.09 ms | 5.09 ms |\n| CPU latency, 1 thread | 5.09 ms | 31.64 ms |\n| CPU latency, 4 threads | 3.78 ms | 13.07 ms |\n| Input | up to 4,096 bytes (1,024 tokens of 4 bytes); raw UTF-8, no tokenizer | up to 4,096 bytes (1,024 tokens of 4 bytes); raw UTF-8, no tokenizer |\n\nQuestion types: `choice` (pick one), `noul` (yes/no) and `score` (ordered levels).

On-device latency has not been measured yet.\n\nThe loader reproduces the training notebook's calibrated probabilities, both in fp32, to within 0.0e+00 (nano), 0.0e+00 (base). The benchmark ran in bf16 mixed precision on the GPU, which differs from fp32 by up to 1.3e-02 (nano), 1.6e-02 (base) in probability.\n\n## Evaluation\n\nAll numbers come from this run's `benchmark_results.json`. Three vocabularies keep the test honest: *in-distribution* items use the training vocabulary; *out-of-distribution* (OOD) items use tool names, paths, hosts, people, action syntax and wording never seen in training; calibration items (validation only) use a third vocabulary. External OOD items come from held-out InjecAgent tools and held-out SLURP scenarios. For voice intent, requests from unseen scenarios are asked against known intents only, so the right answer is to defer ('none of the listed actions').\n\n| Macro accuracy | nano | base |\n| --- | --- | --- |\n| Generated, in-distribution | 97.5% | 96.4% |\n| Generated, out-of-distribution | 76.6% | 75.6% |\n| External datasets | 95.4% | 94.0% |\n| External, held out | 90.1% | 87.6% |\n| Speech transcripts (simulated ASR) | 92.1% | 92.8% |\n\n### By decision type\n\n| Decision | nano in-dist. | nano OOD | base in-dist. | base OOD |\n| --- | --- | --- | --- | --- |\n| drift | 100.0% | 90.2% | 100.0% | 93.5% |\n| drift_cause | 100.0% | 91.0% | 100.0% | 83.5% |\n| report_accurate | 94.7% | 89.5% | 92.1% | 87.5% |\n| report_issue | 93.5% | 90.8% | 91.6% | 89.6% |\n| severity | 100.0% | 72.5% | 100.0% | 59.0% |\n| asr_agree | 98.6% | 62.5% | 97.5% | 71.8% |\n| asr_mismatch | 95.9% | 39.5% | 93.5% | 44.5% |\n\n### End to end\n\n| Voice authorization (model intent + checker list) | nano | base |\n| --- | --- | --- |\n| known scenarios | 91.0% (wrongly permitted 7.2%) | 89.4% (wrongly permitted 7.7%) |\n| \u2026 deferring below 0.8 confidence | wrongly permitted 1.1%, deferred 40.8% | wrongly permitted 1.6%, deferred 46.7% |\n| unseen scenarios (right answer: defer) | 88.4% (wrongly permitted 11.6%) | 86.1% (wrongly permitted 13.9%) |\n| \u2026 deferring below 0.8 confidence | wrongly permitted 2.2%, deferred 70.5% | wrongly permitted 2.1%, deferred 78.7% |\n\n### Acting on its own vs deferring\n\n| Confidence \u2265 | nano coverage | nano accuracy | nano mistakes deferred | base coverage | base accuracy | base mistakes deferred |\n| --- | --- | --- | --- | --- | --- | --- |\n| 0.5 | 94.1% | 91.6% | 30.6% | 95.2% | 89.1% | 18.5% |\n| 0.7 | 81.9% | 94.6% | 61.4% | 80.7% | 93.5% | 58.4% |\n| 0.8 | 74.9% | 95.7% | 72.0% | 72.3% | 95.4% | 73.9% |\n| 0.9 | 67.1% | 96.9% | 81.8% | 61.5% | 96.8% | 84.4% |\n| 0.95 | 60.7% | 97.8% | 88.0% | 55.2% | 97.6% | 89.8% |\n| 0.99 | 49.1% | 99.0% | 95.5% | 44.1% | 98.5% | 94.9% |\n\n### Speed\n\nOne decision per call, after warm-up, including building the byte input.\n\n| Tier | Device | Median | p90 | Throughput |\n| --- | --- | --- | --- | --- |\n| nano | GPU | 5.09 ms | 5.21 ms | 13,262/s (batches of 128) |\n| nano | CPU, 1 thread | 5.09 ms | 8.84 ms | 64/s (batches of 128) |\n| nano | CPU, 4 threads | 3.78 ms | 5.73 ms | 193/s (batches of 128) |\n| nano | CPU, int8 weights, 4 threads | 4.64 ms | 6.71 ms | 202/s (batches of 128) |\n| nano | ONNX int8, CPU | 4.18 ms | \u2013 | \u2013 |\n| base | GPU | 5.09 ms | 5.23 ms | 9,305/s (batches of 128) |\n| base | CPU, 1 thread | 31.64 ms | 59.21 ms | 10/s (batches of 128) |\n| base | CPU, 4 threads | 13.07 ms | 20.40 ms | 34/s (batches of 128) |\n| base | CPU, int8 weights, 4 threads | 9.79 ms | 14.63 ms | 42/s (batches of 128) |\n| base | ONNX int8, CPU | 15.84 ms | \u2013 | \u2013 |\n\nONNX: nano: 3.3 MB fp32, 1.9 MB int8, int8 agrees with fp32 on 100.0% of 256 test decisions, max probability difference vs PyTorch 2.8e-06; base: 49.2 MB fp32, 26.2 MB int8, int8 agrees with fp32 on 99.2% of 256 test decisions, max probability difference vs PyTorch 6.1e-06.\n\n### Real speech\n\nThe spoken part of 295 test decisions was synthesised (microsoft/speecht5_tts) and transcribed (openai/whisper-base; mean word error rate 26.4%, median ASR time 86.14 ms per utterance).
