prompt full-shot first claim
The extracted camera-ready paper text does not match the user-supplied ranking counts, so the ranking claims are partially supported only for the current-paper version.
Mechanism verified in released code
- 8-layer, 8-head Transformer-style encoder with RoPE.
- Separate reconstruction and anomaly heads are present.
- Zero-shot wrapper returns anomaly logits, not reconstruction error alone.
| Head | Loss |
|---|---|
| reconstruction | MSE |
| anomaly | cross entropy |
Generator stages present
- Univariate templates with trend, seasonality, noise, and local changes.
- Multivariate DAG sampling with ARX-style parent dynamics.
- Endogenous/exogenous anomaly paths and token-level labels.

Reduced cloud cross-check
A T4 Hugging Face Job cloned the public repos, generated official synthetic samples, and ran a transparent contextual-anomaly proxy.

toy RCD proxy F1
The proxy favors relative context over one-step reconstruction, but it is not a substitute for the released checkpoint benchmark.
