Automated README summary
Automatically summarized from the README on 20 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A companion measurement lab for dspy-typesafeify and other callers that use TypeSafe decisions inside DSPy-style pipelines. It provides reproducible calibration, confidence-gating, latency, and modeled-cost benchmarks, plus offline replay.
How it uses Jev
Jev makes Choice decisions on support-ticket routing state, returning a selected owner and confidence. The benchmark applies a confidence gate: decisions below the threshold become predicted: null and abstained: true. Metrics like coverage, accuracy among answered, selective risk, Brier score, and ECE are computed from these gated decisions.
Primitives:choicenoul
Technique worth stealing
Confidence-gated abstention with leakage-safe Platt scaling calibration fitted only after the gate is declared.

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.
