+- The injected config's `headers` ARE the credential — `X-MCP-Server-ID`,

+  session-bound, so it cannot be carried anywhere and re-used later; and it sits

+**What is a memory, and what is a session's weather.** A memory records what is

+claim would change depending on which permission mode the session is in, it is

+environment where the claim is simply false. Measured twice: a bullet in
+`mem:connector-allowlist-recovery` was quoted to refuse a design it did not
+describe, and one in `mem:prior-art-and-issue-hygiene` contradicted the standing
