Prior art and IP research with a receipted search trail
The evidentiary problem in patent work is rarely the finding; it is proving what was searched, when, and how thoroughly. When agents run prior art sweeps through the Crux Daemon, every retrieval call mints a receipt recording the query, the corpus, and the moment it ran, hash-chained into an append-only spine. If the completeness of a search is later challenged in prosecution or litigation, the trail replays rather than relying on an analyst's recollection.
Wide sweeps stay affordable because every retrieval call carries a hard token budget and the daemon trims to fit. On the open ScoreCrux benchmark, budgeted retrieval returns far fewer tokens than naive top-K with near-identical answer quality, which is the difference between a landscape you can afford to run monthly and one you run once.
Sensitive material stays put. The daemon runs locally, so unfiled invention disclosures and privileged analysis never leave your infrastructure, and receipts verify offline. For documents that will be filed or shared, C2PA output attestation is available behind a default-off flag.
