This record is unclaimed

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":"pith","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

Tools observed via MCP handshake

get_review — Pith's review of one specific paper, in one call: the verdict, confidence, novelty and correctness scores, one-line summary, weakest assumption, and the
search_papers — Search Pith-reviewed papers by title and abstract. Call this when the user names a research topic, phenomenon, method, or paper title without an identif
latest_reviews — The papers Pith reviewed most recently, newest first. Call this when the user asks what is new, notable, or recently reviewed in a field or overall. day
analyze_paper_claims — The structured argument of one specific paper: what it actually asserts, the premises it assumes, the machinery connecting those premises to the claim,
get_claims — Alias of analyze_paper_claims: the same ledger of what the paper asserts, its premises, machinery, and falsifier, in argument order.
search_claims — Full-text search over every scientific claim Pith has extracted, across all reviewed papers. Call this when the user asks who claims something, whether
get_paper_falsifier — The falsifier for one specific paper's core claim: the concrete observation, experiment, or computation that would settle or disprove it, plus how many
get_falsifier — Alias of get_paper_falsifier: the same falsifier and watcher count.
get_signed_reviews — Published human signed reviews of one paper: reviewer identity, axis deltas against the machine review, claim verdicts, defects, predictions, and who pa
get_reviewer_record — A reviewer's published signed reviews and, when present, their calibration record (Brier score, open predictions, positivity skew). Call this when the u
get_record — The compiled record of one paper: the authors' own sentences, arranged with typed labels. It carries the main claim in the authors' words, each abstract
resolve_paper — Turn a pasted arXiv id, arXiv URL, DOI, or Pith Number into the arXiv id the other tools key on. ``resolved`` is false when the input did not become an
paper_packet — One paper's compiled record, small enough to hold beside others: the main claim and contribution in the authors' words, each abstract sentence with its
citation_neighbors — One hop from a paper: every reference entry with its resolved work identity, the papers that cite it, and, where a record exists, the citing sentences w
paper_bridge — Whether either paper cites the other, the resolved works both cite (on or off arXiv), and the papers that cite both.
paper_connections — What other arXiv papers do with this paper, and what it does with the arXiv papers it cites: builds on, uses the method or tool, uses the data, compares
check_claim — Which arXiv papers support a scientific statement, which contradict it, and which study it without deciding, each with the paper's own main claim quoted
verify_citation — Whether the cited paper's own sentences support what a sentence attributes to it: supports, partly supports (a condition is missing), contradicts, or no
find_passages — Author sentences the classifier labeled with one role, across every stored record, each with its probability and paper. Abstract-tier records cover limi
