OpenChainGraph Suite · Calibration

Decision Boundary Explorer

Pick a compliance node or a gated workflow already in the suite, sweep one or two of its numeric inputs across a range, and see exactly where the decision flips. This is calibration evidence: fair-lending threshold testing, pre-deployment testing, or just understanding how sensitive a policy is to its inputs, before an agent runs it for real.

Read-only over existing kernels: this page re-runs the same deterministic compute() logic each node already ships, it does not change any node, add a kernel, or touch chaingraph.json. The target list below is a curated subset (numeric-threshold nodes and one gated workflow), not the full catalog.

Signature (§16 eddsa-jcs-2022, ephemeral did:key)
Not signed yet. Signing generates a fresh Ed25519 keypair in this tab only — it is not persisted anywhere and proves "this browser produced this calibration," not a durable identity.
Anchoring links out to anchor.ainumbers.co (a separate site, opened by your click, not fetched by this page) to timestamp the execution hash. If a sweep found several flip points, export the artifact and paste its flip_points hashes into anchor.ainumbers.co's batch tool (anchor_batch) to anchor all of them in one Merkle-batched call.
