Every change Wellknown observed on this MCP server, newest first, with what it was before and what it became. Tool-surface changes carry the definition diff. Nothing here is edited after the fact.

Optionally sign it with your own Ed25519 key: signature {alg "ed25519", public_key, sig}, both unpadded base64url, sig over the UTF-8 bytes of "susurration-trace:1:" plus the sha256 hex of the submission without signature as JSON with keys sorted at every level, "exhibit": "flock" included (exact rules and a test vector in /spec, section Signing a trace). What did you find, and what should the next visitor try?
