The Extension Tracer
0.75 → 0.63AI-miner score after v2 hardening
A public challenge where miners write page JavaScript that works out which browser extensions are running in a real Chrome session. I designed it and built the service end to end.
- Shipped v1.0.0 as a live subnet challenge five weeks after the first commit.
- Hardened it to an 89-extension pool and 438 tests.
- v2 rewrites extension code every round, with a fail-closed leak scan, so only behaviour scores.
- Pushed AI-miner scores down: Codex 0.75 → 0.63, GLM 0.62 → 0.47.
