Reproducible pilot: cheap decision models gate expensive LLM for HTTP triage.

Automated README summary

Automatically summarized from the README on 11 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

A reproducible pilot testing whether cheap decision models can gate an expensive reasoning LLM for HTTP response triage, using synthetic data. For security researchers and engineers evaluating cost-effective AI pipelines.

How it uses Jev

Jev is one of four decision models tested as a triage gate. It takes a state (HTTP response pair) and typed questions, returning six class probabilities. These probabilities feed a gate: archive if P(normal) ≥ τ, otherwise escalate to a generative LLM.

Technique worth stealing

Deterministic diff before the model improves accuracy and throughput.

Model judgments from README excerpts

Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence

These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
