Persistent memory for AI coding agents, shared across every project and harness.
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":"arcane-mcp","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.

Agents save the decisions, bugs and patterns they work through. The next session, in any harness, finds them again with keyword and semantic search. Everything stays on your machine: one SQLite database plus a Markdown copy you can read and grep. Secrets are redacted before anything is written or sent to the embedding model. ```bash arcane search "why were cus…
