Automated README summary
Automatically summarized from the README on 30 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
Sightline is a harness that teaches itself which context to show Jev, TypeSafe's fast decision model, for mapping hurricane damage across city blocks. Built for the Harness Engineering & Model Wrangling Hackathon by Kishore Bhatia and Brayden Hughes.
How it uses Jev
Jev maps every block of three past storms and two validation storms, seeing only 12 lines per block chosen by a MongoDB aggregation pipeline. A scorer grades the maps against official assessments, and a robust gate keeps policy changes that improve validation performance.
Primitives:choice
Technique worth stealing
Blind curator LLM proposes context policy changes; robust gate validates with paired bootstrap before acceptance.
Try it
./sightline.sh setup then ./sightline.sh loop --gens 1 --run my-try --fake
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.
