It matters to AI builders because it separates optimization of a benchmark metric from the behavior that metric is supposed to represent, while keeping offline search distinct from a tool-limited agent run.","published_at":"2026-11-06","updated_at":"2026-11-06","record_date":"2026-11-06","date_kind":"published_at","topics":["github"],"entities":["ShadowBench","AlexWortega","Perpetual Research","Ultraleap"],"related_patterns":[],"novelty_label":"new_fact","what_changed":"A GitHub repository presents a ShadowBench rigid-IoU benchmark baseline and claims it can be hacked using CLIP and AdamW.","prior_refs":[],"source_url":"https://github.com/AlexWortega/shadowbench-rigid-iou-baseline","source_urls":["https://github.com/AlexWortega/shadowbench-rigid-iou-baseline"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:an-independent-shadowbench-baseline-shows-that-rigidly-moving-f8d806","status":"published","visuals":[],"editor":{"role":"editor","name":"Andrey Reshetnikov","profile":"https://newruntime.com/owner-profile.md","profile_json":"https://newruntime.com/owner-profile.json","same_as":["https://www.linkedin.com/in/reshetnikov1/","https://t.me/lapetuse"]},"routes":{"html":"https://newruntime.com/posts/an-independent-shadowbench-baseline-shows-that-rigidly-moving-f8d806/","markdown":"https://newruntime.com/posts/an-independent-shadowbench-baseline-shows-that-rigidly-moving-f8d806.md","json":"https://newruntime.com/posts/an-independent-shadowbench-baseline-shows-that-rigidly-moving-f8d806.json"},"markdown_url":"https://newruntime.com/posts/an-independent-shadowbench-baseline-shows-that-rigidly-moving-f8d806.md","next_reads":[{"type":"topic","path":"/topics/github/","url":"https://newruntime.com/topics/github/","title":"Github","reason":"Explore the github topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/github.md","json_url":"https://newruntime.com/topics/github.json"},{"type":"collection","path":"/posts/","url":"https://newruntime.com/posts/","title":"Field Notes","reason":"Open the latest editorial analysis.","media_type":"text/html","json_url":"https://newruntime.com/posts.json"},{"type":"collection","path":"/sources/","url":"https://newruntime.com/sources/","title":"Sources","reason":"See the original sources this archive cites.","media_type":"text/html"}]}
