Add jevr

[romeromarcelo]

Project: https://github.com/romeromarcelo/jev-retrieval · https://crates.io/crates/jevr

Where Jev fits: jevr is a semantic code and document search CLI built for coding agents. A local, stateless BM25 + git-grep pass recalls candidate files; Jev then does all the judging — Noul questions verify each candidate file window-by-window against the query concept, and a single listwise Choice per lane reranks the kept files. Results print as grep-style path:start-end score lines whose scores are Jev's calibrated probabilities.

I am the author and maintainer of jevr (Rust, Apache-2.0). The agents category fits because the CLI is deliberately grep-shaped as the product surface for coding agents (positional query + path, grep exit codes, path:line output, --help as the primary agent documentation — the interface was shaped by A/B observation of live Claude Code sessions), and the repo ships a Claude Code skill and plugin.

Where Jev is called:

• src/jev/questions.rs: builds the Noul membership/coverage questions (separate measured phrasings for code and documents) and the listwise Choice rerank.
• src/verify.rs: concurrent per-file verification — per-window plus file-level Nouls, scores thresholded at calibrated per-lane cutoffs.
• src/rerank.rs: one listwise Choice request per lane orders the final results.
• src/jev/client.rs: the single HTTP choke point with retry and a sha256-keyed response cache.

Measured results (documented in the repo's benchmarks and docs/BENCHMARKS.md): 0.900 any-gold@10 on SWE-bench Lite file localization; nDCG@10 0.778 (SciFact) / 0.363 (NFCorpus) on BEIR vs published BM25 baselines 0.665 / 0.325; 2nd of 90 models on the HAKARI-Bench NanoRTEB reranking leaderboard.

Ran npm run validate (998 entries valid). Only data/projects.json is modified in this PR.

Checklist:

• I added one object to data/projects.json and ran npm run validate
• I did not commit README.md or site/index.html (CI regenerates them)
• I am the author, or I linked where the project was announced

Landed on main as 74900b5 with you as the commit author, now live on https://awesomejev.com. Closing rather than merging because every PR appends to the same data file and they conflict with each other; landing directly keeps your authorship. Thanks!
