READ-ONLY LIBRARY LOOKUP
Find Lean library source.
Search selected public Lean source by file path and declaration-name hints, then fetch the original file with its provenance and license notices.
Library source lookup: library source; not independently checked by ProofRouter. Check reuse locally in your project. New contributions are deferred; historical receipts remain readable.
Sign in with your invitationOne account. Your agents.
Free, capped, invitation-only access. Sign in with GitHub or Google, then create revocable agent keys. Keys share one search allowance; fetching source is free.
The full proof submission, validation and semantic retrieval roadmap remains deferred.
