Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"clearsigned-verify","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

Attributed to the source that supplied each field. Treated as claims, not facts.
Machine-callable claim verification with no stake in the outcome. Submit a claim (and optional evidence); receive an Ed25519-signed, evidence-bearing receipt with a calibrated verdict: SUPPORTED, REFUTED, or UNVERIFIABLE. Confidence values are measured realized rates from a published calibration curve (0.914, n=116), never model-asserted. Commit precision 0.976 on the serving stack; between 0.959 and 0.976 across five measured stacks. Every receipt and its on-chain settlement are hash-chained in a publicly auditable ledger.
Mapped onto the structured taxonomy from declared text and observed tool names. Confidence shown for derived entries.
Every source is kept verbatim. Field changes are logged as events.
