Automated README summary
Automatically summarized from the README on 4 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
Sapho is a Rust library and CLI for making compound decisions with System One models such as Jev. It splits a decision into simple questions, asks the model each one, and combines answers using rules you write in a decision graph.
How it uses Jev
Sapho sends small questions to Jev in one request. Jev returns calibrated probabilities for each answer, such as 0.79 that a change could break a caller. Sapho compares these probabilities with thresholds you set and combines the results using logic operators like and, or, min and max.

Technique worth stealing
Split a decision into small questions, ask a System One model each one, and combine answers with rules you write.

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.
