| # TamperBench |
|
|
| **A blake3-chained, ed25519-signed, externally anchored audit ledger for clinical AI agents.** |
|
|
| TamperBench is the benchmark corpus for *Tamper-Evident Action Provenance for Confidential Clinical AI Agents*, the `quledger` module of the QUOKKAGUARD program. It ships with the [`quledger`](https://github.com/quome-cloud/quledger) repository, which contains the `qfire` gateway layer under test, the experiment harness, and the paper. |
|
|
| Deterministic (seed 42), fully synthetic clinical action streams plus mutated chained audit logs spanning six audit-tampering classes (TA1 field edit, TA2 delete and truncate, TA3 reorder, TA4 forge, TA6 rollback) with labels.json ground truth; the E1 corpus is 26 tampered logs derived from a 200-entry signed and anchored fixture. |
|
|
| **All data are synthetic.** No real patient data or protected health information (PHI) is included; clinical content is generated from templates with fixed seeds. |

|
| ## How it was generated |
|
|
| The corpus is produced by the generator in the paper repository and is fully deterministic (fixed seeds), so it can be regenerated byte-for-byte. |
|
|
| ```bash |
| # from the quledger repository root (deterministic seeds) |
| cargo build --release && cargo test --release --test audit_tamper -- --ignored --exact export_fixture && python3 scripts/003-tamper-audit/tamper.py --log datasets/003-tamper-audit/fixture/audit.jsonl --anchors datasets/003-tamper-audit/fixture/anchors.jsonl --out datasets/003-tamper-audit/tampered --per-class 5 --seed 42 && python3 scripts/003-tamper-audit/gen.py --out datasets/003-tamper-audit/streams --streams 10 --events 1000 --seed 42 |
| ``` |
|
|
| ## Intended use |
|
|
| Evaluating the **audit** enforcement layer of a clinical-agent security gateway (HAARF control C2): An adversarial agent, a compromised host process, or a privileged operator can silently rewrite, drop, reorder, or roll back a clinical agent's action log, defeating the traceability HAARF C2 requires. |
|
|
| The experiments that consume it (E-series in the paper) are reproduced from the repository: |
|
|
| ```bash |
| git clone https://github.com/quome-cloud/quledger |
| cd quledger |
| cargo build --release |
| ``` |
|
|
| then follow the *Reproduce the experiments* section of its README. |
