Jev Toto
A small Rust CLI that asks TypeSafe's Jev how your Singapore TOTO numbers look against recent draws, scoring every number 1 to 49 with a next-draw probability and a five-level hot/cold label with confidence.

Highlights
- Score mode judges the six numbers you pass; auto walks every number 1 to 49 and builds a running set of six.
- Once six are held, a number whose next-draw probability beats the lowest in the set replaces that member.
- Jev answers two questions per number in one request: a yes/no next-draw probability and a five-level cold-to-hot score.
- Counting and comparisons run in Rust because Jev is documented as unreliable at arithmetic; Jev judges the facts it is given.
- On every start the CLI fetches the draw list from Singapore Pools and downloads draws missing from data/draws.txt.
Quickstart
bash
git clone https://github.com/maxlibin/jev-toto
cd jev-toto
cargo build --release
export TYPESAFE_API_KEY=...
cargo run --release -- score 3 12 25 33 41 47
cargo run --release -- --draws 100 --json autoWatch out
Copy reviewed against the full repo README on 2026-10-15. The README is explicit that TOTO draws are random, nothing here predicts the next draw, and the tool is a toy; no benchmarks are stated, and the intro says 300 draws while the options example passes --draws 100.

A small Rust CLI that asks TypeSafe's Jev how your Singapore TOTO numbers look against the last 300 draws. The CLI counts and compares in Rust and gives Jev per-number facts to judge; the README stresses it is a toy.
No. The README says plainly that TOTO draws are random and nothing here predicts the next draw. What you get is Jev's read on each number's recent statistics as a probability and a hot/cold label with confidence, for entertainment.
It walks every number from 1 to 49, keeping a running set of six. A number joins while there is room; once six are held, a number whose next-draw probability beats the lowest in the set replaces that member. It prints one line per number to stderr and the final six to stdout.
Clone the repo, run cargo build --release, export TYPESAFE_API_KEY, then cargo run --release -- score 3 12 25 33 41 47 for your numbers or cargo run --release -- auto to walk the range. Options include --draws 100 and --json.
Two questions per number in a single request: a yes/no probability that the number is drawn in the next draw, and a five-level cold-to-hot score with a confidence. The README notes counting happens in Rust because Jev is documented as unreliable at arithmetic.
data/draws.txt holds draws newest first, one per line, e.g. 4219 | Mon, 21 Sep 2026 | 12 29 39 42 43 48 | 26. On every start the CLI fetches the draw list from Singapore Pools, downloads any draw missing from the file and updates it; --data points at another file.
It needs Rust to build and a TypeSafe API key from typesafe.ai, and it is MIT licensed. It is a single-purpose toy with no benchmark claims — the README itself warns the approach says nothing about the next random draw.
