AEC-DS: Adaptive Erasure Coding with PDP-Triggered Reputation and QoS-Aware Migration for Decentralized Storage

arXiv:2607. 17460v1 Announce Type: new Abstract: In decentralized storage systems, audit results are often not used directly to guide later redundancy and shard-placement decisions, which can lead to inefficient resource allocation and delayed recovery.

AuditFL: A Contract-Backed Clearing Layer for Open Federated Learning

AuditFL introduces a contract-backed clearing layer that enables auditable federated learning in open settings by keeping training and aggregation off chain while recording only content identifiers and economic state on chain. Clients reserve update tickets with deposits, publish update identifiers, and claim refunds or rewards, while the task coordinator publishes global checkpoints and finalizes rounds through deterministic settlement rules. Experiments on MNIST with up to 200 clients show that AuditFL preserves the learning trajectory with manageable overhead and remains robust under stress tests, keeping accuracy changes within a few tenths of a percentage point.

Trustworthy Runtime Error Healing in Real-World Repositories: A Benchmark and Guardrail

The paper introduces HealBench, a benchmark of 265 runtime errors from 18 real-world repositories, and HealGuard, a safety framework that restricts healing code to an analyzable subset of Python and applies static and dynamic taint analysis. Using these tools, the authors evaluate a dedicated healing method and three general coding agents powered by different LLM backbones, achieving a 38.11% resume rate and a 28.68% test‑pass rate, while HealGuard flags 17.4% of successful healings as potentially unsafe. The study demonstrates that current LLM agents can meaningfully repair real repository crashes, but also highlights significant safety concerns that the Guardrail framework can detect, albeit with a high false‑positive rate.

The Acknowledgment Point Is the System: Durable Policy-Decision Receipts for AI Audit Evidence

The paper presents RuntimeGuard‑AI, a prototype that links each deterministic AI policy decision to its source code, writes a privacy‑minimizing record at a chosen synchronization point, and returns an Ed25519‑signed receipt indicating whether the write succeeded. After a crash, the system validates the integrity of records, manifests, shard placement, sequence continuity, and replay identity, while an independent attestation path chains committed records into signed Merkle epochs for auditor verification. Performance results on an Apple M4 Pro show high throughput (up to 27,193 requests/s) with low latency when buffering, but throughput drops and latency rises when per‑record data and full synchronization are used, illustrating a clear durability‑latency trade‑off.
