Web4: Verifiable Presence for AI
AI is already taking actions in the world. We can’t prove what it did. Web4 is the open standard that closes that gap.
An open standard for verifiable AI presence — proposed by Metalinxx Inc., owned by no one. Research-stage. web4-core v0.3.0 public on crates.io + PyPI (web4-trust-core at v0.2.0); reference implementation + a runnable society hub public; no production deployment yet. STATUS.md is the calibration — read it before judging the claims below.
Proof point: 0% → 94.85% on ARC-AGI-3 with the same Claude Opus 4.6, structured around Web4 patterns via the SAGE harness. Public scorecard. The model didn’t change — the structure around it did. Read precisely: this is real capability under affordances a strict competition run withholds — the harness analyzed the games’ public engine source to build solver cartridges, so it shows what the model does given engine-level context, not blind from-observation solving.
