+- Host id after pairing: \`${pairing.hostId}\`

+1. Read the JSON discovery file and use its loopback \`host\` and \`port\`. Refuse any non-loopback address.
+2. POST this exact JSON to \`http://HOST:PORT/pair\` with \`Content-Type: application/json\`:
+
+\`\`\`json
+{"code":"${pairing.pairingCode}"}
+\`\`\`
+
+3. The successful response contains \`credential\`. Save only that value, followed by a newline, in a new private local file owned by the current user. On POSIX systems set the file mode to \`0600\`. Never print, quote, log, or place the credential in chat, Skill text, shell history, source control, or the MCP JSON itself.
+4. Replace the placeholder below with that credential file's absolute path, then merge this MCP server into this Harness's local MCP configuration while preserving all other servers:
+
+\`\`\`json
+${JSON.stringify(mcp, null, 2)}
+\`\`\`
+
+5. Restart or reload this Harness's MCP services if required. Run one real MemHub recall query and report whether the tool was discovered and the authenticated query succeeded. Do not report success merely because files were written.
+
+The pairing code is single-use. If pairing fails or the code has expired, stop and ask the user to generate a new Skill in MemHub. Do not guess codes, reuse another Harness's credential, disable authorization, or broaden permissions.
